Description

{Battery Cell Activation System that Significantly Shortens Battery Cell Transfer Time}

The present invention relates to a battery cell activation system that significantly reduces the transport time of battery cells.

The material described in this section merely provides background information for the present embodiment and does not constitute prior art.

In general, secondary batteries are rechargeable and can be expanded in capacity, and representative examples include nickel cadmium, nickel hydrogen, and lithium ion batteries. Secondary batteries can be manufactured in a flexible pouch type, in which case they have the advantage of being relatively free in shape.

A secondary battery includes a pouch and a battery cell. A secondary battery is configured to have a cell pouch with battery cells placed inside, and a polymer outer material corresponding to the pouch surrounds the battery cell.

Meanwhile, inspections must be conducted to determine whether the manufactured secondary battery has the electrical characteristics as designed and whether there are any short-circuits in each cell. Accordingly, the manufactured secondary battery cells are transferred from the cell tray to the activation device, and are placed in the activation device to be activated.

At this time, since the secondary battery cells have a considerably thin film form, there is a risk of damage or detachment during the transport process. Accordingly, in the past, when transporting the manufactured secondary battery cells from the cell tray to the activator, only a small number of secondary battery cells were gripped and the transport was performed at a relatively significantly slow speed. For example, when transporting the battery cells to the activator that performs activation by settling 36 battery cells at a time, the battery cells were gripped and transported two at a time from the cell tray and placed (transported) to the activator. Accordingly, in order for the activator to activate the characteristics of the battery cells, the battery cells had to be transported a total of 18 times before activation could be performed. Since the shape of the battery cell cannot be changed, the above-mentioned problem could not be avoided in the past.

One embodiment of the present invention aims to provide a battery cell activation system capable of significantly reducing the transport time of battery cells.

According to one aspect of the present invention, a battery cell activation system is provided, comprising: a cell tray transport device which receives a cell tray storing battery cells to be activated, and enables the battery cells to be gripped and transported; a battery cell transport device which grips and transports battery cells to be activated from a cell tray arranged at a position close to the cell tray transport device; a transport tray on which battery cells transported by the battery cell transport device are placed; a battery cell activator which activates electrical characteristics of battery cells mounted on the cell tray in a preset environment; and a stacker crane which grips the transport tray and transports it as a whole to the battery cell activator and places it therein.

FIG. 1 is a plan view of a battery cell activation system according to one embodiment of the present invention, and FIG. 2 is a front view of a battery cell activation system according to one embodiment of the present invention.

Referring to FIGS. 1 and 2, a battery cell activation system (100) according to one embodiment of the present invention includes a cell tray transport device (110), a battery cell transfer device (120), a transfer tray (130), a stacker crane (140), a battery cell activation device (150), and a control device (not shown).

The battery cell activation system (100) activates battery cells, particularly battery cells loaded into a pouch-type battery. The battery cell activation system (100) applies preset pressure and temperature to the battery cells, and causes each battery cell to repeat charging and discharging in a situation where the temperature and pressure are applied, thereby imparting or activating electrical characteristics to the battery cells.

At this time, the battery cell activation system (100) transfers all battery cells to be activated at once using the transfer tray (130) when transferring the battery cells in the cell trays transported from the cell tray transport device (110) to the battery cell activator (150) to activate them, rather than transferring the battery cells one by one. Since the battery cells to be activated are transported while being secured in the transfer tray (130), the occurrence of damage or detachment during the transport process can be fundamentally prevented. In addition, since there is no concern about damage or detachment during the transport process, the battery cell activation system (100) can transfer the battery cells at a significantly faster speed than in the past when transferring them to the battery cell activator (150) to activate them.

The cell tray transport device (110) receives cell trays storing battery cells to be activated, and allows the battery cell transport device (120) to grip and transport them. The cell tray transport device (110) includes a space in which the cell trays can be placed, and includes a transport means for transporting the placed cell trays, such as a conveyor belt or rollers. Accordingly, the cell tray transport device (110) receives the aforementioned cell trays to a location (112 or 118), and moves the introduced cell trays clockwise (in the direction of 114, 116, and 118 when introduced through 112) or counterclockwise (in the direction of 116, 114, and 112 when introduced through 118) from the location. For example, a situation in which a cell tray is introduced to a first location (118) in the cell tray transport device (110) will be described. When a cell tray is introduced into the first position (118), the cell tray transport device (110) moves the battery cell transport device (120) to the second position (116), which is a position where the battery cells in the cell tray can be gripped. As the battery cells are transported, the empty cell tray moves to the third position (114) and the fourth position (112) and is discharged to the outside. If the cell tray is introduced into the fourth position (112) in the cell tray transport device (110), the reverse is true.

When a cell tray is introduced or discharged to the first position (118) or the fourth position (112) of the cell tray transport device (110), the cell tray may be positioned at the corresponding position and then moved up and down. For example, assuming that the cell tray is introduced to the first position (118) and discharged from the fourth position (112), the first position (118) of the cell tray transport device (110) may initially be lowered. Thereafter, when the cell tray including the battery cell for activation moves to the first position (118), the first position (118) of the cell tray transport device (110) is raised and lowered. The cell tray transport device (110) raises and lowers the first position (118) and then moves the cell tray to the second position (116). Conversely, when the empty cell tray moves to the fourth position (112), the cell tray transport device (110) lowers the fourth position (112) and discharges the empty cell tray to the outside.

The battery cell transport device (120) picks up and transports battery cells to be activated from a cell tray placed at a location (114 or 116) close to the device.

The battery cell transfer device (120) grips battery cells that are relatively densely arranged within a cell tray, distributes the battery cells at appropriate intervals, and transfers them to a transfer tray (130). A description of each component of the battery cell transfer device (110) will be described later with reference to FIGS. 3 to 9 and FIGS. 19 to 21.

The transfer tray (130) places battery cells to be transferred by the battery cell transfer device (120). The transfer tray (130) places battery cells (requiring activation) inside itself, and places them in the state in which the battery cells for activation should be placed in the battery cell activator (150). Accordingly, when the transfer tray (130) is transferred as a whole by the stacker crane (140) and settled in the battery cell activator (150), activation can be performed on all battery cells placed in the transfer tray (130) in the battery cell activator (150). As the battery cells are placed in the transfer tray (130), all battery cells requiring activation can be transferred at once, and damage or detachment can not occur during the transfer process. The specific structure of the transfer tray (130) will be described later with reference to FIGS. 10 and 11.

The stacker crane (140) picks up the transfer tray (130) and transports it as a whole to the battery cell activator (150). The stacker crane (140) moves back and forth between the position where the transfer tray (130) is arranged and the position where each battery cell activator (150) is arranged, and transports the transfer tray (130) to each battery cell activator (150). As shown in FIGS. 1 and 2, each battery cell activator (150) is arranged within a certain space and can be arranged in an m*n configuration. The stacker crane (140) moves on three axes, picks up the arranged transfer tray (130), and settles the picked transfer tray (130) to the battery cell activator at an appropriate position. The specific structure of the stacker crane (140) will be described later with reference to FIGS. 12 to 14.

The battery cell activator (150) creates a preset environment for a plurality of battery cells to be installed and activates electrical characteristics. The battery cell activator (150) receives each transport tray (130) transferred by the stacker crane (140). Since the transport tray (130) is received by the stacker crane (140) moving on three axes, it can be placed in a stacked form without having to be placed on only one plane as in the related art. Accordingly, in order for the plurality of activators to activate the battery cells in parallel, a plurality of activations can be performed simultaneously in a relatively narrow area without having to secure a space having an excessively large area as in the related art.

The battery cell activator (150) electrically connects to the installed battery cell, and then applies a preset pressure and a preset temperature to the battery cell. The battery cell activator (150) can apply relatively uniform pressure and temperature to each battery cell compared to the prior art. In a state where pressure is applied to each battery cell, the battery cell activator (150) supplies power to each battery cell. The battery cell activator (150) repeatedly charges and discharges the battery cell in the aforementioned situation. When the battery cell is repeatedly charged and discharged in the aforementioned environment, the battery cell is given electrical characteristics and activated. The battery cell activator (150) activates the battery cell by performing the aforementioned operation. A description of each component of the battery cell activator (150) will be described later with reference to FIGS. 15 to 18.

A control device (not shown) controls the aforementioned operations of each component within the battery cell activation system (100).

FIG. 3 is a perspective view of a battery cell transport device according to one embodiment of the present invention.

Referring to FIG. 3, a battery cell transfer device (110) according to one embodiment of the present invention includes a first rail (310), a second rail (315), a first motor (320), a second motor (323), a third motor (326), a guide body (330), a screw (340), a nut (350), a first shaft (360), a battery cell transfer (370), and a fixed frame (380).

The first rail (310) is formed as an axis (x-axis, hereinafter referred to as 'first axis') connecting the cell tray transport device (110) and the arranged transport tray (130). The first rail (310) is arranged on a support (305) having a preset height (z-axis direction) so that the guide body (330) can move along the first axis.

The first rails (310) are positioned so that two guide bodies (330) can be placed on each of the first rails (310). The first rails (310) are positioned so that a fixed frame (380), a second rail (315), and a guide body (330) can be placed therebetween, so that the guide body (330) is placed, thereby allowing the fixed frame (380) and a battery cell transfer (370) connected thereto to be placed.

The second rail (315) is connected to one side of the guide body (330) and is formed with an axis (z-axis, hereinafter referred to as “second axis”) that moves the fixed frame (380) connected thereto closer to or further away from the cell tray or transfer tray (130) placed at the second position (116) or the third position (114) of the cell tray transport device (110). The second rail (315) is connected to one side of the guide body (330) and moves together with the guide body (330) moving along the first rail (310). Meanwhile, the second rail (315) is connected to the fixed frame (380) on the other side so that the fixed frame (380) and the battery cell transfer (370) connected thereto can move in the first axis direction together with the guide body (330). At the same time, the second rail (315) allows the fixed frame (380) and the battery cell transfer (370) to move on the second axis.

The second rail (315) is also arranged in two pieces facing each other so that a fixed frame (380) can be arranged on each second rail (315). The second rails (315) are positioned apart from each other by the length (on the second axis) of the fixed frame (380) so that the fixed frame (380) and the battery cell transfer (370) connected thereto can be arranged.

The first motor (320) supplies power to the guide body (330) to move along the first axis on the first rail (310). The first motors (320) can be placed on each of the first rails (310), and the two can be linked to each other to supply power of the same size.

The second motor (323) supplies power to the fixed frame (380) connected to one side of the second rail (315) to raise and lower on the second axis. The second motor (323) can also be placed on each of the second rails (315), and the two can be linked to each other to supply power of the same size.

The third motor (326) supplies power to move the two battery cell transfers (370) closer to or further away from each other along the first shaft (360) (moving on the first axis).

The guide body (330) is connected to the first rail (310) on one side and to the second rail (315) on the other side, and moves the second rail (315) along the first axis. For example, the guide body (330) is implemented in an ‘L’ shape, and is connected to the first rail (310) on the lower side (the side facing the activator or tray) and to the second rail (315) on the side. In particular, a guide part (not shown) that can move along the first rail (310) is formed on the lower side, and can move along the first axis by receiving power from the first motor (320). Meanwhile, since the guide body (330) is connected to the second rail (315) on the other side, the second rail (315) and the fixed frame (380) that moves along the second rail (315) move together along the first axis. Accordingly, the fixed frame (380) and the battery cell transfer (370) connected thereto can be moved along the first axis by the guide body (330) to approach the tray (140) or to approach the battery cell activator (150).

The screw (340) and nut (350) are powered by the third motor (326) to move each battery cell transfer (370) away from or closer to each other on the first axis.

The screw (340) is powered by the third motor (326) and rotates. The screw (340) is placed on a fixed frame (380) and is fixed so that it can rotate without being displaced from its original position. Meanwhile, the nut (350) is located outside (farther from the center) than the connection part (413, described later with reference to FIG. 4) inside the battery cell transfer (370) with respect to the center of the screw (340), and moves closer to or farther from the center of the screw (340) as the screw (340) rotates. The connection part (413) inside the battery cell transfer (370) is placed at a position of the screw (340) and moves together with the movement of the nut (350).

The first shaft (360) is arranged coaxially with the screw (360) on the fixed frame (380) to support the battery cell transfer (370). The connection part (416) inside the battery cell transfer (370) is mounted on the first shaft (360). The connection part (416) moves on the first shaft (360) along with the movement of the battery cell transfer (370) (by the nut (350)). Accordingly, the weight of the battery cell transfer (370) is not applied entirely to the screw (340), but is distributed to the first shaft (360) and the screw (340). The first shaft (360) supports the weight of the battery cell transfer (370) and increases the life of the screw (340).

The battery cell transfer (370) moves along the first axis by the guide body (330) and along the second axis by the fixed frame (380), and captures and transfers battery cells in the tray (140) or the battery cell activator (150). The battery cell transfer (370) moves along the first axis by the guide body (330) moving along the first rail (310), and along the second axis by the fixed frame (380) moving along the second rail (315). Accordingly, it can move to and toward the tray (140) containing the battery cells for activation or the battery cell activator (120) that has completed activation.

Meanwhile, the battery cell transfer (370) is connected to the screw (340) and the first shaft (360) and grips the battery cell. The battery cell transfer (370) moves to the cell tray or the transfer tray (130) according to the operation of the above-described configuration. However, the respective battery cells arranged within the two are arranged with different widths (lengths along the axes perpendicular to both the first axis and the second axis). Accordingly, the battery cell transfer (370) can move the respective grippers (Gripper, described later with reference to FIG. 9) along the axis perpendicular to both the first axis and the second axis (y-axis, referred to as the 'third axis' hereinafter) to grip the battery cells within the cell tray or to place the gripped battery cells on the transfer tray (130). Since the spacing between battery cells in the tray (140) or battery cell activator (150) is determined respectively, each gripper is positioned at the same spacing as each spacing to grip each battery cell. A specific description of the battery cell (370) will be described later with reference to FIG. 9 and FIGS. 19 to 21.

The fixed frame (380) is connected to each second rail (315) and fixes the screw (340), the nut (350), the first shaft (360) and the battery cell transfer (370). The fixed frame (380) is connected to each second rail (315) between the second rails (315), moves along the second axis along the second rail (315), and moves along the first axis along the guide body (330) connected to the second rail (315), allowing the parts fixed to it to move together with it.

FIGS. 4 and 5 are perspective views of a battery cell transfer according to one embodiment of the present invention.

Referring to FIGS. 4, 5a and 5b, a battery cell transfer (370) according to one embodiment of the present invention includes a frame (410), a first connecting portion (413), a second connecting portion (416), a rail (420, 425), a sliding groove (430), a sliding coupling portion (435), a first link member connecting portion (440), a second link member connecting portion (445), a link member (450), a battery cell gripper (460), a motor (470), a screw (480), a nut (485), a first sensor (490) and a second sensor (495).

The frame (410) provides a space for each component within the battery cell transfer (370) to be located or operated, and is connected to the fixed frame (380) to support each component within the battery cell transfer (370).

The two frames (410) are positioned to face each other with respect to the fixed frame (380), so that two battery cell transfers (370), including the frame itself, can be positioned to face each other with respect to the fixed frame (380).

The first connecting portion (413) is a structure that protrudes from the frame (410) toward the fixed frame (380), and is combined with the screw (340) to move the battery cell transfer (370) on the first axis. The first connecting portion (313) is implemented in a shape that can be combined with the screw (340), for example, a shape that includes a hollow portion (not shown) having a cross-sectional area equal to or larger than the cross-sectional area of the screw (340) inside, and is connected to the screw (340). The first connecting portion (313) is combined with the screw (340), and allows itself (313) and the entire frame (410) to move accordingly by the operation of the screw (340) and the nut (350). Accordingly, the first connecting portion (313) moves the battery cell transfers (370) facing each other in a direction closer to or farther away from each other.

The second connecting portion (316) is a structure that protrudes from the frame (410) toward the fixed frame (380) like the first connecting portion (313), and is coupled with the first shaft (360) to support the weight of the battery cell transfer (370). The second connecting portion (316) is coupled with the first shaft (360) and moves together with the first connecting portion (313) on the first shaft (360) according to the movement of the first connecting portion (313). The second connecting portion (316) is not moved by a separate power source, but is passively moved by the movement of the first connecting portion (313). The second connecting portion (316) is coupled with the first shaft (360) and supports the weight of the battery cell transfer (370) by distributing it together with the first connecting portion (313).

Rails (420, 425) are formed at corresponding positions centered on the sliding groove (430) on the frame (410) to prevent the battery cell gripper (460) from coming off and move it. The battery cell gripper (460) is connected to the rail (420, 425) by a guide part (916, described later with reference to FIG. 9) and moves along the rail (420, 425) along the third axis. That is, each gripper (460) moves in the same direction along the third axis and moves in a direction closer to or farther away from each other.

However, a pair of rails is not formed as only one within the frame (410), but two or more rails may be formed. As described above, the guide part (916) within the battery cell gripper (460) is connected to the rail and moves on the rail. However, in order to grip the battery cells arranged within the tray (140), the gap between each battery cell gripper (460) must be significantly narrowed. The gap between each battery cell gripper (460) may have to be narrower than the guide part (916). At this time, if only one pair of rails is formed within the frame (410), a problem occurs in that each battery cell gripper (460) does not have the gap required to grip the battery cells arranged within the tray (140). To solve this problem, two or more pairs of rails are formed within the frame (410), and adjacent battery cell grippers (460) are connected to different rails via the guide part (916) and move on the rail. Accordingly, any spacing may be provided between each battery cell gripper (460).

A sliding home (430) is formed in a third axis shape within the frame (410), so that the sliding joint (435) moves along the third axis within itself.

The sliding coupling part (435) moves closer to or further away from each other within the sliding groove (430) by the operation of the motor (470), the screw (480), and the nut (485). The screw (480) is arranged on the third axis, and the nut (485) is arranged on the screw (480) and is coupled with a part of the sliding coupling part (435) and moves together with it. Power is supplied from the motor (470) and the screw (480) rotates, and the sliding coupling part (435) moves closer to or further away from each other along the sliding groove (430) according to the rotation of the screw (480). A part of the sliding coupling part (435) can protrude from the inside of the frame (410) (in the direction in which the two frames face each other) to the outside of the frame (410) (in the direction in which the two frames do not face each other) through the sliding groove (430). As the sliding joint (435) protrudes, the link member can be connected to the protruding portion of the sliding joint (435).

The first link member connecting portion (440) has a hinge structure and fixes the link member (450) and the battery cell gripper (460) so that the link member (450) rotates. The first link member connecting portions (440) at both ends close to the sliding coupling portion (435) are connected to the link member (450) and the battery cell gripper (460), but are connected to the sliding coupling portion (435), so as to receive a force in the third axis direction from the sliding coupling portion (435) and transmit it to the link member (450) and the battery cell gripper (460).

Meanwhile, the second link member connecting portion (445) has a hinge structure and is connected to each of the link members (450a and 450b) to allow the link members (450) to rotate.

Link members (450a, 450b) are arranged in a pair that intersects in an 'X' shape, and a first link member connection part (440) is connected to the intersection (center) of the two members, and a second link member connection part is connected to each end of the link member (450). A more specific structure is described with reference to FIGS. 6 to 8.

FIG. 6 is an enlarged view of a link member and a link member connecting portion according to one embodiment of the present invention, FIG. 7 is a cross-sectional view of a first link member connecting portion according to one embodiment of the present invention, and FIG. 8 is a cross-sectional view of a second link member connecting portion according to one embodiment of the present invention.

Referring to FIG. 6(a) and FIG. 6(b), when the link member (450) and the link member connecting portions (440, 445) are connected in this manner, and when the first link member connecting portion (440) receives an external force in the third axis direction from the sliding connecting portion (435), each link member (450) connected to the first link member connecting portion (440) rotates. The link members (450) rotate so as to move away from each other (the angle therebetween increases) or closer to each other. For example, when the link members (450) connected to the first link member connecting portion (440) move away from each other, each link member connected to the second link member connecting portion (445) moves closer to each other (the angle therebetween decreases). In this way, as the link members connected to the first link member connecting portion (440) move away from each other and the link members connected to the second link member connecting portion (445) move closer to each other, the sliding coupling portion (435) moves closer to each other and the gap between the respective battery cell grippers (460) connected to the first link member connecting portion (440) decreases. Conversely, when the link members (450) connected to the first link member connecting portion (440) move closer to each other, the respective link members connected to the second link member connecting portion (445) move away from each other. In this way, as the link members connected to the first link member connecting portion (440) move closer to each other and the link members connected to the second link member connecting portion (445) move away from each other, the sliding coupling portion (435) moves away from each other and the gap between the respective battery cell grippers (460) connected to the first link member connecting portion (440) increases. As the link member (450) and each link member connecting portion (440, 445) are combined as described above, the gap between each battery cell gripper (460) is adjusted using the force transmitted from the sliding connecting portion (435).

At this time, since each link member (450) is intersected and connected in an 'X' shape, a link member (450b) that is positioned relatively close to the frame (410) and a link member (450a) that is positioned farther from the frame (410) are distinguished at any link member connection portion (440, 445). At this time, the link member (450b) includes a protrusion (610) that protrudes in a direction toward the link member (450a) at both ends (in a direction away from the frame (410). A joining hole (615) into which a joining member (not shown) such as a screw can be joined is implemented within the protrusion (610). The joining member (not shown) is joined to the joining hole (615), and the joining member (not shown) comes into physical contact with the link member (450a) connected to the second link member connection portion (445). By using this, the joining member (not shown) joined to the joining hole (615) can adjust the degree to which the link member (450a) rotates at the second link member connecting portion (445). Even if the link member (450) and the link member connecting portions (440, 445) are manufactured under the same process conditions and in the same environment, a microscopic tolerance inevitably occurs. As a result, even if the gap between each battery cell gripper (460) is adjusted to be as close as possible (by moving the sliding connecting portions (435) to each other as close as possible), the gap between each battery cell gripper (460) may vary slightly due to the tolerance described above. This may not be fatal if the gap between battery cells is above a certain level, such as in the battery cell activator (150). However, if the gap between battery cells is below a certain level, such as the gap between battery cells arranged in the tray (140), the error described above may be fatal. To resolve this, the link member (450b) includes a protrusion (610) and a joining hole (615), and the joining member (not shown) can be joined to each joining hole (615) at a preset depth. Here, the preset depth means a depth such that the gap between the first link member joining portions (440) is the same when the link members joined to the second link member joining portions (445) are close to each other. The depth at which the joining member (not shown) is joined to the joining hole (615) in each link member (450b) may be different from each other. Accordingly, even if a tolerance occurs in each configuration during the manufacturing process, this can be resolved by joining the joining member (not shown) to each joining hole (615) at a preset depth.

Meanwhile, the first link member connecting portion (440) is connected to the link member (450) and the battery cell gripper (460) as shown in FIG. 7.

Referring to FIG. 7, the first link member connecting portion (440) is connected to each link member (450a, 450b) and bearings (710a to 710d), and a spacer (720) is arranged for each bearing (710a to 710d). The first link member connecting portion (440) includes the bearing (710) and the spacer (720) so that no tolerance (playback) occurs in the direction of the rotation axis.

On the other hand, the second link member connecting portion (445) is connected to each link member (450a, 450b) as shown in FIG. 8.

Referring to FIG. 8, the second link member connecting portion (445) also includes a bearing (710) and is connected to the link member (450), but instead of including a spacer, it includes a stopper (810) at the outermost side (farthest from the frame) to prevent the bearing (710) from coming off.

Since the link member connecting parts (440, 445) have different shapes, the following advantages are provided. Since the first link member connecting part (440) connects not only the link member but also the battery cell gripper (460), it does not allow any movement in the direction of the rotation axis. However, if the bearings (710) continuously rotate and operate without any play, the bearings (710) may be worn or damaged.

On the other hand, since the second link member connecting portion (445) has axial play, wear and damage like the first link member connecting portion (440) are prevented, and the reduction in lifespan due to fatigue occurring in the bearing (710) in the first link member connecting portion (440) can be buffered.

Referring again to FIGS. 4 and 5, a plurality of battery cell grippers (460) are implemented (as many as the number of battery cells) to grip each battery cell. The specific structure of the battery cell gripper (460) will be described later with reference to FIGS. 9 and 19 to 21.

The motor (470), screw (480) and nut (485) perform the aforementioned operation and move the sliding coupling (435) from the sliding groove (430) to the third axis. As the sliding coupling (435) moves, the link members (450) rotate along with it by the link member connecting members (440, 445) and adjust the spacing between the respective battery cell grippers (460).

The first sensor (490) senses whether the battery cell gripper (460) has completely gripped the battery cell. The first sensor (490) determines whether the second frame (920, described later with reference to FIG. 9 and FIGS. 19 to 21) has risen to a preset height or higher. The first sensors (490) are arranged at both ends of the frame (410), and one of them irradiates light and the other receives light at a preset height (in the second axis direction) based on when the second link frame (920) has descended the most. If the battery cell gripper (460) grips the battery cell without any particular abnormality, the second link frame (920) descends along the slide rail (912, described later with reference to FIG. 9) due to the weight of the battery cell. Unless there is any particular abnormality, the second link frame (920) maintains the state of having descended along the slide rail (912). On the other hand, if a battery cell or other configuration collides with the battery cell gripper (460), the second link frame (920) may rise. The first sensor (490) detects such an abnormal rise of the second link frame (920) within the battery cell gripper (460) and determines whether the battery cell gripper (460) has completely gripped the battery cell or whether an abnormality has occurred.

The second sensor (495), on the other hand, senses whether the battery cell gripper (460) is holding a battery cell. The second sensor (495) is also positioned at both ends of the frame (410) like the first sensor (490), with one sensor irradiating light and the other receiving light. However, unlike the first sensor (490), the second sensor (495) transmits and receives light at a position lower than the height at which the battery cell can be positioned in the second axis direction when the battery cell gripper (460) has held a battery cell. The second sensor (495) transmits and receives light at the corresponding height and senses whether the battery cell gripper (460) has released the battery cell it is holding.

FIG. 9 is a drawing illustrating the configuration of a battery cell gripper according to one embodiment of the present invention.

Referring to FIG. 9, a battery cell gripper (460) according to one embodiment of the present invention includes first to third link frames (910 to 930), a slide rail (912), a link member fixing pin (914), a guide portion (916, 925), a stopper support portion (918), an actuator (940), a cylinder (950), a hinge shaft (960), a bearing (965), a grip portion (970), a grip body (974), a grip protrusion (978), an angle detection sensor (980), an angle adjustment shaft (985), a sensor fixing hole (987), a first stopper (990), and a second stopper (995).

The first link frame (910) is connected to the rails (420, 425) and supports the remaining components within the battery cell gripper (460). The first link frame (910) uses a guide portion (916) to enable the battery cell gripper (460) to be connected to the rails (420, 425) and to move along the third axis along the rails.

The third link frame (930) supports configurations capable of gripping battery cells within the battery cell gripper (460).

The second link frame (920) connects the first link frame (910) and the third link frame (930).

The slide rail (912) is formed within the first link frame (910) so that the second link frame (920) can be raised and lowered (on the second axis) along the guide portion (925). The second link frame (920) is normally lowered by its own weight or by the weight of the battery cell when the grip portion (970) holds the battery cell.

However, if the grip portion (970) fails to hold the battery cell and collides with the battery cell or other components, the second link frame (920) is raised and lowered along the slide rail (912). If the slide rail (912) does not exist, when the grip portion (970) and other components collide, the impact force is directly transmitted to each component. This may cause damage to the grip portion (970) or other components (such as battery cells). The slide rail (912) prevents damage to each component in the aforementioned situation.

As illustrated in FIG. 9c, the link member fixing pin (914) protrudes in the direction in which the first link member connecting portion (440) is coupled to the battery cell gripper (460), thereby fixing the first link member connecting portion (440) to the battery cell gripper (460). Accordingly, the first link member connecting portion (440) can couple the link member (450) and the battery cell gripper (460).

The guide member (916) is connected to the rail (420, 425) and moves the first link frame (910) and all components connected or formed therewith on the real (on the third axis).

A stopper support member (918) is formed at the end far from the rail (420, 425) of the first link frame (910) to provide a space for placing a stopper (990, 995). The stopper support member (918) places and supports the stopper (990, 995).

The actuator (940) is connected to the cylinder (950) and raises and lowers the cylinder (950) (on the second axis) so as to be closer to or further away from the grip projection (978). The actuator (940) is implemented as a pneumatic cylinder or the like and supplies power to raise and lower the cylinder (950) connected to it.

The cylinder (950) is positioned within the third link frame (930) and is raised and lowered by receiving power from the actuator (940). The cylinder (950) is positioned within a guide tube (not shown) formed to have a cross-sectional area equal to or larger than its own cross-sectional area within the third link frame (930), and is raised and lowered without disengagement. Meanwhile, the end (955) close to the grip projection (978) of the cylinder (950) is implemented in a wedge shape. Since the corresponding end (955) of the cylinder (950) is implemented in a wedge shape, the cylinder (950) can naturally enter between the grip projections (978) without resistance while descending.

At this time, the cylinder (950), particularly the end (955) having a wedge shape, may be implemented with a heat-treated component. Conventionally, the cylinder (950) has been implemented with a resin gel or a non-heat-treated component, but there was a problem that it quickly wears out due to many contacts with grip protrusions, etc. To prevent this, the cylinder (950), particularly the end (955), is implemented with a heat-treated component to minimize wear.

The hinge axis (960) allows the grip body (974) to rotate around itself. The hinge axis (960) is located at a point of the grip body (974) and allows the grip body (974) to operate on the principle of a lever. That is, when the grip protrusions (978) are spread apart by the end (955) of the cylinder, the gap between the grip portions (970) narrows, and when the end (955) of the cylinder is separated and the gap between the grip protrusions (978) narrows, the gap between the grip portions (970) widens.

The bearing (965) and the grip body (974) are connected to the hinge axis (960) and rotate around the hinge axis and operate on the lever principle. The grip body (974) is implemented in two pieces, and a part of the position where the hinge axis is to be placed is etched in the shape of the hinge axis (960) so that the hinge axis (960) can be placed. Since two grip bodies (974) must be placed with the hinge axis in the middle, one of the grip bodies (974) is etched in a semicircle. The bearing (965) is placed on the etched portion. The bearing (965) is placed, and the grip body (974) rotates around the hinge axis (960) so that the grip portion (970) and the grip protrusion (978) operate on the lever principle.

Here, the bearing (965) may be implemented as two parts having different diameters at one end and the other end, such as a flange bearing, and having a step. The other ends (ends with relatively smaller diameters) of the two parts may be arranged to face each other, and accordingly, a space is formed in the bearing (965) (between one end of each part) in which a part of the grip body (974) may be arranged. The distance between the one end of each part in the bearing (965) may be implemented to be the same as the thickness of a part of the grip body (974), so that the bearing (965) and the grip body (974) may be prevented from being separated from each other.

The grip portion (970) is formed with a preset area at one end of the grip body (974) and moves closer or farther away from each other depending on the operation of the cylinder (950) to hold the battery cell.

The grip portion (970) is formed with a preset area at one end of the grip body (974). As described above, the grip body (974) is implemented in two pieces, and the grip portion (970) is also formed on each grip body (974). The grip portion (970) has a preset area, so that when a battery cell is located between the gaps between the grip portions (970), the battery cell can be gripped with the area. Accordingly, damage to the grip portion (970) or the battery cell that may occur when gripping at one point is prevented.

The grip projection (978) is formed in a protruding shape at the other end of the grip body (974). The grip projection (978) protrudes in a cylindrical shape so that the end (955) of the cylinder can smoothly enter between the grip projections (978). When the end (955) of the cylinder enters between the grip projections (978), the two (978) spread apart and the gap of the grip portion (970) is reduced.

The angle detection sensor (980) detects whether a battery cell is placed between the grip portions (970). The angle detection sensors (980) are placed on each battery cell gripper (460) and are placed facing each other to irradiate light from one to the other. However, the angle detection sensors (980) are not placed on the same line, but are placed diagonally, such as in the '/' direction, to irradiate and receive light. When the angle detection sensors (980) irradiate light on the same line, there may be cases where the battery cell is not detected. To resolve this, a pair of angle detection sensors (980) are placed diagonally to detect the battery cell.

The angle adjustment shaft (985) adjusts the light emission direction and light reception direction of the angle detection sensor (980). The angle adjustment shaft (985) is arranged adjacent to the angle detection sensor (980) and changes the light emission direction and light reception direction of the angle detection sensor (980) according to its own rotation. In order to grip the battery cell in the tray (140), each battery cell gripper (460) moves to have a relatively narrow gap. Accordingly, light irradiated from the angle detection sensor (980) in one battery cell gripper (460) can proceed to the angle detection sensor (980) in another adjacent battery cell gripper (460). The angle adjustment shaft (985) adjusts the light emission direction and light reception direction of the angle detection sensor (980) in each battery cell gripper (460) to prevent the occurrence of the above-described problem.

The sensor fixing hole (987) enables the angle detection sensor (980) whose angle is adjusted by the angle adjustment shaft (985) to be fixed. The sensor fixing hole (987) receives a fixing means (not shown, for example, a fixing bar, etc.) into its interior so that the angle adjustment shaft (985) prevents the angle detection sensor (980) from tilting (adjusting the light-emitting direction and light-receiving direction) any longer.

The first stopper (990) is arranged on the lower surface of the stopper support (918) facing the third link frame (930) to prevent damage due to collision between the cylinder (950) and the stopper support (918). The cylinder (950) can be raised to the stopper support (918) by receiving power from the actuator (940). At this time, if there is no separate configuration, the cylinder (950) and the stopper support (918) may collide, and a problem may occur in which one or both of them is damaged. To prevent this, the first stopper (990) is arranged on the aforementioned surface of the stopper support (918) to prevent damage to both (918, 950).

The second stopper (995) is arranged between the stopper support (918) and the second link frame (920) on the upper surface of the stopper support (918) (the surface opposite to the surface on which the first stopper is arranged), thereby preventing collision between the second link frame (920) and the stopper support (918), and reducing the lateral moment generated in the guide portion (916) due to movement of the battery cell gripper (460).

The second stopper (995) is positioned at the aforementioned location to prevent damage to both the second link frame (920) and the support member (918) due to collision, like the first stopper (990).

The second stopper (995) reduces the lateral moment occurring in the guide portion (916). The guide portion (916) has a characteristic of being vulnerable to the lateral moment that inevitably occurs. In particular, since the weight of all components of the battery cell gripper (460) is applied to the guide portion (916), the guide portion (916) becomes vulnerable to the lateral moment (moment in the first axis direction and the third axis direction). To prevent this, the stopper support portion (918) and the second stopper (995) have the structure shown in Fig. 9d.

The second stopper (995) includes a groove (997) that is recessed toward its center on a surface facing the stopper support (918). Meanwhile, the stopper support (918) includes a protrusion (999) that protrudes toward the second stopper (995) in a shape corresponding to the groove (997) on a surface facing the second stopper (995). In this way, when the second stopper (995) is placed on the stopper support (918), the groove (997) and the protrusion (999) are additionally combined. Accordingly, the guide part (916) becomes more robust to the moment applied to the first axis (x-axis direction in FIG. 9d) and the third axis (y-axis direction in FIG. 9d) by the combination of the two (997, 999), and (unnecessary and unintended) movement of the second link frame (920) toward the corresponding axis can be minimized.

At this time, the protrusion (999) can be implemented as a headless bolt, and a screw thread can be implemented in the stopper support (918). The protrusion (999) is connected to the stopper support (918) by screw connection, and the degree of protrusion can be adjusted. Accordingly, the bonding strength (fastening force) of the protrusion (999) and the stopper support (918) can be improved, and the degree of protrusion of the protrusion (999) can also be adjusted as needed.

Meanwhile, in Fig. 9d, a groove (997) is implemented in the second stopper (995) and a protrusion (999) is implemented in the stopper support (918), but this is not necessarily limited to this. The groove (997) may be implemented in the stopper support (918) and the protrusion (999) may be implemented in the second stopper (995) and may have the above-described features.

FIG. 19 is a drawing illustrating a configuration of a battery cell gripper according to another embodiment of the present invention, and FIG. 20 is an enlarged view of a portion of a battery cell gripper according to another embodiment of the present invention.

Referring to FIGS. 19 and 20, a battery cell gripper (460) according to another embodiment of the present invention includes first to third link frames (910 to 930), a slide rail (not shown), a link member fixing pin (not shown), a guide portion (not shown), a stopper support portion (not shown), an actuator (940), a plate detection sensor (1910, 1915), a plate fixing portion (1920), a plate (1930), a guide groove (1935), an LM guide (1940), a hinge shaft (960), a bearing (965), a grip portion (970), a grip protrusion (1950), a grip body (1960), an angle detection sensor (980), an angle adjustment shaft (985), a first stopper (990), and a second stopper (995). Here, the first to third link frames (910 to 930), the slide rail (not shown), the link member fixing pin (not shown), the guide portion (not shown), the stopper support portion (not shown), the actuator (940), the hinge shaft (960), the bearing (965), the grip portion (970), the angle detection sensor (980), the angle adjustment shaft (985), the first stopper (990), and the second stopper (995) perform the same operation as the same configuration in the battery cell gripper (460) according to one embodiment of the present invention, and therefore, a detailed description thereof will be omitted.

The plate detection sensor (1910, 1915) detects the movement of the actuator (940) and thus detects the movement of the plate (1930). The plate (1930) is raised or lowered according to the operation of the actuator (940). The plate detection sensor (1910, 1915) detects the actuator (940) that raises or lowers the plate (1930) and thus detects whether the plate (1930) is raised or lowered. According to the physical connection between the grip projection (1950) and the guide groove (1935) in the plate (1930), the grip portion (970) physically moves together with the movement of the plate (1930). That is, detecting the movement status of the plate (1930) is equivalent to detecting the movement status of the grip portion (970). If a foreign substance is located between the grip parts (970) and the gap between the grip parts (970) cannot be narrowed, the movement of the plate (1930) is also restricted. The plate detection sensor (1910, 1915) detects the movement of the plate (1930) in this way and determines whether the gap between the grip parts (970) cannot be narrowed or widened due to a foreign substance, etc.

The plate fixing member (1920) transmits power transmitted from the actuator (940) to the plate (1930). The plate fixing member (1920) is connected to the actuator (940) at one end and to the plate (1930) at the other end, and transmits power transmitted from the actuator (940) to the plate (1930). Accordingly, the plate fixing member (1920) and the plate (1930) are raised or lowered according to the power provided by the actuator (940).

The plate (1930) is raised and lowered by the actuator (940) and the gap between the grip parts (970) is adjusted.

The plate (1930) includes at least two guide grooves (1935) at the opposite end from which the plate fixing member (1920) is positioned. Each guide groove (1935) is formed at the end of the plate (1930) in a direction perpendicular to the direction of movement of the plate (1930), but is formed in the form of an oblique line in which one of the ends approaches the other. A grip projection (1950) is arranged in the guide groove (1935). When the plate (1930) is raised or lowered, the grip projection (1950) moves along the guide groove (1935), and the grip body (974) and the grip portion (970) are rotated by the hinge axis (960). Accordingly, the gap between the grip portions (970) becomes closer or farther apart. In this way, the plate (1930) includes a guide groove (1935), and by arranging a grip projection (1950) within the guide groove (1935), the grip portion (970) etc. rotates.

The LM guide (1940) is arranged between the third link frame (930) and the plate (1930) to assist in the raising and lowering of the plate (1930). The LM guide (1940) assists in the raising and lowering of the plate (1930) at the aforementioned location and prevents the plate (1930) from being deviated from the moving axis.

The grip projection (1950) is formed in a protruding shape at the other end (the end farthest from the grip portion) of the grip body (974), or is connected (to the grip body) in a protruding shape at the other end of the grip body (974) and moves along the guide groove (1935). The grip projection (1950) includes a fixed shaft (2054) and a rotating roller (2058) arranged on the outside thereof. The rotating roller (2058) comes into contact with one surface of the guide groove (1935) and moves along the guide groove (1935) according to the raising and lowering of the plate (1930). As described above, since the guide grooves (1935) are formed diagonally, and one end of each groove is formed so that it approaches the other, the spacing between the grip projections (1950) remains constant even when the plate (1930) is raised and lowered, but the relative positions of the grip projections (1950) before and after the plate (1930) is raised and lowered change. Accordingly, the grip projections (1950) move along the guide grooves (1935), and the grip body (974) and the grip portion (970) rotate by the hinge axis (960).

The grip body (1960) includes a grip portion (970) formed or connected to a predetermined area at one end, and a grip projection (1950) formed or connected to a protruding shape at the other end. The grip body (1960) has a thickness equal to the spacing of the space formed within the bearing (965) as described above, excluding the grip portion (970) and the grip projection (1950). Accordingly, the grip bodies (1960) have a form in which they are stacked one above the other. Accordingly, the grip projections (1950) also have spacing between themselves in the upper and lower directions.

Meanwhile, the grip portion (970) may include a silicone-coated surface (975) as a surface facing each other. The silicone-coated surface (975) is formed by coating a silicone component on the surface facing each other between the grip portions (970), and may improve the gripping force of the grip portion (970) for the battery cell by improving the frictional force. In the past, the silicone was implemented in a form in which it was adhered to the aforementioned surface of the grip portion, but after a certain period of time, the silicone may detach from the grip portion and fall off into the battery, etc. To prevent this, the grip portion (970) may include a silicone-coated surface (975).

FIG. 21 is a drawing illustrating the configuration of a battery cell gripper according to another embodiment of the present invention.

Referring to FIG. 21, a battery cell gripper (460) according to another embodiment of the present invention includes first to third link frames (910 to 930), a slide rail (not shown), a link member fixing pin (not shown), a guide portion (not shown), a stopper support portion (not shown), an actuator (940), a cylinder (950), a grip projection guiding plate (2110), a guide groove (2115), a hinge shaft (960), a bearing (965), a grip portion (970), a grip projection (2130), a grip body (1960), a grip projection fixing portion (2120), an angle detection sensor (980), an angle adjustment shaft (985), a first stopper (990), and a second stopper (995). Here, the first to third link frames (910 to 930), the slide rail (not shown), the link member fixing pin (not shown), the guide portion (not shown), the stopper support portion (not shown), the actuator (940), the hinge shaft (960), the bearing (965), the grip portion (970), the grip body (1960), the angle detection sensor (980), the angle adjustment shaft (985), the first stopper (990), and the second stopper (995) perform the same operation as the same configuration in the battery cell gripper (460) according to one embodiment of the present invention or the battery cell gripper (460) according to another embodiment of the present invention, and therefore, a detailed description thereof will be omitted.

The grip projection guiding plate (2110) is connected to the end (close to the grip projection) of the cylinder (950) and rotates the grip portion (970) according to the movement of the cylinder (950).

The grip projection guiding plate (2110) is connected to the aforementioned end of the cylinder (950) and rises and falls along with the rise and fall of the cylinder (950).

At this time, the grip projection guiding plate (2110) includes at least two guide grooves (2115). The guide grooves (2115) are each formed in the same direction as the moving direction of the grip projection guiding plate (2110), but are formed in the form of an oblique line in which one end of each of the guide grooves approaches each other. The grip projection (2130) is arranged in the guide groove (2115), and the grip portion (970), etc., rotates as described above.

Meanwhile, a grip projection fixing part (2120) is formed at the other end of the grip body (1960), and a grip projection (2130) is formed or connected in a protruding form to the grip projection fixing part (2120). The grip projection fixing part (2120) formed in the grip body (1960) positioned at the bottom has a form protruding upward, and the grip projection fixing part (2120) formed in the grip body (1960) positioned at the top has a form protruding downward. Accordingly, the grip projection fixing part (2120) has a surface in contact with the grip projection guiding plate (2110) having the same area.

As the grip projection fixing portion (2120) is formed, the grip projections (2130) can be positioned at the same height in the direction in which the grip projection guiding plate (2110) moves. The grip projections (2130) are formed at the same height, and move closer or further away from each other along the guide groove (2115) to rotate the grip portion (970).

FIG. 10 is a perspective view of a transport tray according to one embodiment of the present invention.

Referring to FIG. 10, a transport tray (130) according to one embodiment of the present invention includes a frame (1010), a protrusion (1020), a reinforcing frame (1025), a guide portion (1030), a support sheet support portion (1040), a support sheet (1050), and a restoration member (1070).

The frame (1010) provides a space in which the remaining configuration within the transfer tray (130) can be implemented, and allows the battery cell activator (140) to be placed on the configuration. The frame (1010) has a long rectangular shape along one axis, so that the support sheet supports (1040) and the battery cells (1060) to be placed on the support sheet (1050) can be arranged in a parallel manner along the axis.

A protrusion (1020) is implemented along the longitudinal axis of the frame (1010). The protrusion (1020) may have a structure that protrudes in a 'ㄷ' shape from the frame (1010) along the longitudinal axis of the frame (1010). As the protrusion (1020) is implemented, a stacker crane (140) to be described later can grip the protrusion (1020) to transport the transport tray (130).

The reinforcing frame (1025) is connected to the frame (1010) at one end and to the protrusion (1020) at the other end, thereby structurally reinforcing the protrusion (1020). As described above, the protrusion (1020) is a portion that is gripped by the stacker crane (140), and corresponds to a portion where an external force is applied. Accordingly, as the reinforcing frame (1025) is implemented in the form described above, the protrusion (1020) is structurally reinforced, thereby making the protrusion (1020) more resistant to external force.

The guide part (1030) is implemented in a form connected to both ends of the frame (1010) in the long axis direction, so that the support sheet support part (1040) can move along it.

The support sheet support member (1040) is included in a number that is one more than the number of battery cells (1060) to be activated at one time, and supports the support sheet (1050). As the support sheet support member (1040) included in a number that is one more than the total number of battery cells (1060) to be activated included in the cell tray supports the support sheet (1050), each battery cell (1060) can be settled on the support sheet (1050) supported by the support sheet support member (1040).

As the support sheet support member (1040) has the structure illustrated in FIG. 11, it can move along the guide member (1030) and move away from or closer to each other while supporting the support sheet.

FIG. 11 is a perspective view of a support sheet support according to one embodiment of the present invention.

Referring to FIG. 11, a support sheet support member (1040) according to one embodiment of the present invention includes a support sheet support bar (1110), a support sheet link member (1115), a support sheet fixing member (1120), a link frame (1130), a link home (1135), and a guide hole (1140).

The support sheet support bar (1110) supports the support sheet with its upper surface, including the upper and lower surfaces implemented as planes. In order to fully support the support sheet (1050), the upper surface of the support sheet support bar (1110) is implemented as a flat surface. Meanwhile, the lower surface of the support sheet support bar (1110) is also implemented as a flat surface so that it can be fully seated on the battery cell activator (150), more specifically, on the jig plate (1530) described below.

A support sheet link portion (1115) is implemented at both ends (in the longitudinal direction) of a support sheet support bar (1110). The support sheet link portion (1115) is implemented at both ends of the support sheet support bar (1110) and is structurally combined with a link groove (1135) in a link frame (1130) so that the support sheet support bar (1110) can be combined with the link frame (1130). For example, since the support sheet link portion (1115) has a structure that protrudes in the height direction (the axial direction connecting the upper and lower surfaces of the support sheet support bar) from the support sheet support bar (1110), it is combined with a link groove (1135) implemented so that the inlet has a narrower width than the link groove, so that at least the support sheet support bar (1110) does not detach from the link frame (1130) in the longitudinal direction.

The support sheet fixing member (1120) is coupled with the support sheet support bar (1110) and fixes the support sheet (1050). With the support sheet support bar (1110) and the support sheet fixing member (1120) separated, the support sheet (1050) is placed on the support sheet support bar (1110). Thereafter, the support sheet fixing member (1120) is coupled onto the support sheet support bar (1110) and fixes the support sheet (1050).

The link frame (1130) is coupled to both ends of the support sheet support bar (1110) in the longitudinal direction to connect the support sheet support bar (1110) and the guide hole (1140). The link frame (1130) includes a link groove (1135) inside to be coupled with the support sheet support bar (1110), and its upper surface is coupled with the guide hole (1140). Accordingly, the support sheet support part (1040) can be coupled and fixed to the guide part (1030) by the guide hole (1140), and the support sheet support part (1040) can be moved along the guide part (1030).

As described above, the link frame (1130) is coupled with the support sheet support bar (1110), including the link home (1135). The link home (1135) is implemented to have an entrance implemented with a relatively narrow width and an interior implemented with a wider width, so that the support sheet link portion (1115) can be introduced into its interior and coupled with itself. Accordingly, the two components (1115, 1135) are coupled, and the support sheet support bar (1110) and the link frame (1130) are completely coupled in the longitudinal direction.

The guide hole (1140) is coupled with the link frame (1130) at the top of each link frame (1130) and includes a through hole to allow the guide part (1030) to pass through its interior. As the guide part (1030) passes through the guide hole (1140), the support sheet support part (1040) can move closer or further away from each other along the guide part (1030).

Referring again to FIG. 10, the support sheet (1050) is supported by the support sheet support member (1040) so that a battery cell (1060) can be placed thereon.

The restoring member (1070) is arranged between each of the support sheet supports (1040), more specifically, the guide holes (1140) of each of the support sheet supports (1040), to prevent distortion of the two support sheet supports (1040) connected thereto and maintain balance. For example, the restoring member (1070) may be implemented with an elastic material, such as a spring. Accordingly, when each of the support sheet supports (1040) moves closer to or farther away from each other, the restoring member (1070) enables each of the support sheet supports (1040) to move without distortion and while maintaining balance. As described below, the support sheet supports (1040) are moved closer to or farther away from each other by the battery cell activation device (150), and the restoring member (1070) enables the support sheet supports (1040) to move uniformly without distortion.

Additionally, the restoration member (1070) can assist in restoration by applying a restoring force so that the support sheet support members (1040) return to a position close to each other or an initial shape by the battery cell activator (150). As described above, the restoration member (1070) can be implemented with an elastic material. The restoration member (1070) can assist in restoration by applying a restoring force to the support sheet support members (1040), thereby allowing the support sheet support members (1040) to return to a position close to each other or an initial shape more quickly and smoothly by the battery cell activator (150). For example, the support sheet support member (1040) arranged most centrally can be fixed within the frame (1010). In this case, the support sheet supports (1040) can be moved away from each other, and when the movement is completed, they are arranged close to each other with respect to the center of the transfer tray (130) by the restoration member (1070) (as illustrated in FIG. 10). Since the support sheet supports (1040) are arranged close to each other with respect to the center of the transfer tray (130) in a situation where they are not moved, the two ends of the frame (1010) and the support sheet supports (1040) can be positioned apart from each other in the long axis direction. Accordingly, when the transfer tray (130) is settled onto the battery cell activator (150) by the stacker crane (140), it is possible to prevent the battery cell (1060) from colliding with other components in the battery cell activator (150).

FIG. 12a is a perspective view of a stacker crane according to the first embodiment of the present invention.

Referring to FIG. 12A, a stacker crane (140) according to one embodiment of the present invention includes a grip frame (1210), a grip portion (1215), a guide portion (1220), a motor (not shown), a support frame (1230), a connecting portion (1235), a link frame (1240), a roller (1243), a guide portion (1246), a frame contact surface (1249), a crane (1250), a guide rail (1260), a guide body (1270), and a motor (1280).

The grip frame (1210) moves along the third axis or the longitudinal axis of the transport tray (130) along the guide portion (1220) and grips the protrusion (1020) of the transport tray (130) using the grip portion (1215). The grip frame (1210) moves along the third axis or the longitudinal axis of the transport tray (130) and moves closer to or further away from the transport tray (130) in the corresponding axial direction. The operation of the grip frame (1210) and the structure of the grip portion (1215) are illustrated in FIG. 13.

FIGS. 13a and 13b are drawings illustrating an example of operation of a grip frame according to a first embodiment of the present invention, and FIG. 13c is a drawing illustrating a shape in which a grip frame according to the first embodiment of the present invention grips a transport tray.

Referring to FIGS. 13a and 13b, as described above, the phage frame (1210) moves along the guide portion (1220) in the longitudinal axis direction of the transport tray (130), and moves closer to or further away from the transport tray (130) in the axial direction.

Referring to FIG. 13c, the grip frame (1210) includes a grip section (1215), and the grip section (1215) includes a plurality of connecting plates (1310), a grip plate (1320), a first hinge (1330), and a second hinge (1335).

The connecting plate (1310) is connected to the phage frame (1210) on one side and to the phage plate (1320) on the other side, thereby connecting the two (1210, 1320).

The grip plate (1320) is connected to the connecting plate (1310) on one side, and comes into contact with the protrusion (1020) of the transfer tray (130) on the other side, and grips the transfer tray (130). The grip plate (1320) may be implemented as a flat surface, but may include a groove (not shown) having the same shape as the protrusion (1020) within a portion (more preferably, a central portion) thereof. Accordingly, when the grip plate (1320) comes into contact with the protrusion (1020), the protrusion (1020) is settled within the groove (not shown), thereby allowing it to be more completely fixed and gripped.

The first hinge (1330) connects the grip frame (1210) and each connecting plate (1310) with a hinge structure, so that the connecting plate (1310) rotates. Each connecting plate (1310) is connected to the grip frame (1210) by the first hinge (1330), and moves in a direction parallel to the grip frame (1210) or in a direction perpendicular thereto (in the direction toward the protrusion).

The second hinge (1335) connects each connecting plate (1310) and the grip plate (1320) with a hinge structure, so that the grip plate (1320) rotates. Even if each connecting plate (1320) moves (rotates) in the aforementioned direction by the first hinge (1330), the second hinge (1335) causes the grip plate (1320) to continuously rotate in a direction parallel to the protrusion (1020).

As the gripper (1215) has the structure described above and operates, the gripper frame (1210) can grip the protrusion (1020) of the transfer tray (130).

Referring again to FIG. 12, the guide part (1220) allows the grip frame (1210) to move along itself. The guide part (1220) is arranged toward the long axis direction of the third axis or the transport tray (130) and allows the grip frame (1210) arranged on it to move along itself in the same axial direction. The grip frame (1210) may be arranged and connected to the guide part (1220) by a structure such as a rail (not shown).

A motor (not shown) supplies power to the phage frame (1210) to move along the guide member (1220). Accordingly, the phage frame (1210) can move in the long axis direction of the third axis or the transport tray (130).

The support frame (1230) is implemented in an 'L' shape and supports a guide part (1220) or a guide part (1220) and a motor (not shown) on the lower side, and is connected to a link frame (1240) on the side. The support frame (1230) is coupled to a link frame (1240) on the side, particularly, a guide part (1246) formed within the link frame (1240) and a roller (not shown), and moves up and down along the guide part (1246) within the link frame (1240). Meanwhile, the support frame (1230) supports a guide part (1220) or a guide part (1220) and a motor (not shown) on the lower side, and moves up and down the components it supports together with itself. As a result, the grip frame (1210) can move in the second axis direction.

The connecting portion (1235) is implemented at a position within the support frame (1230), more preferably at the upper portion of the side, and is connected to a rope (not shown) within the crane (1250). The connecting portion (1235) is connected to a rope (not shown) within the crane (1250) and allows the support frame (1230) to be raised and lowered by receiving power from the crane (1250).

The link frame (1240) is connected to the support frame (1230) and the guide body (1270), and allows the support frame (1230) to move along with itself, while allowing the support frame (1230) to move together with the movement of the guide body (1270). As described above, the link frame (1240) is connected to the support frame (1230), and is connected to the guide body (1270) by the frame contact surface (1249). Accordingly, the link frame (1240) allows the support frame (1230) to be raised and lowered by the crane (1250) (the gripping frame moves in the second-axis direction), while allowing the support frame (1230) to move in the first-axis direction by the movement of the guide body (1270).

A roller (1243) is implemented at one end of the link frame (1240) (the end furthest from the frame contact surface) so that a rope (not shown) within the crane (1250) can be connected from the crane (1250) to the connecting portion (1235), while at the same time, power can be smoothly transmitted from the crane (1250) to the connecting portion (1235) by the rope (not shown).

The guide part (1246) is implemented on one side of the link frame (1240) and is combined with the support frame (1230) to enable the support frame (!230) to move along the link frame (1240).

The crane (1250) includes a rope (not shown) and applies an attractive force or a repulsive force to a configuration connected to itself by winding the rope (not shown). The crane (1250) is arranged on one side of the link frame (1240) and winds the rope (not shown) including the rope (not shown). At this time, as described above, since the rope (not shown) is connected to the connecting portion (1235) in the support frame (1230), when the crane (1250) winds the rope (not shown), the support frame (1230) can be raised or lowered along the rope (not shown).

The guide rail (1260) is arranged in the first axis direction so that the guide body (1270) arranged on it can move along the first axis.

The guide body (1270) is coupled to the guide rail (1260) on one side and connected to the frame contact surface (1249) of the link frame (1240) on the other side, so that the link frame (1240) connected thereto and the guide body (1270) can move along the guide rail (1260) on the first axis. Accordingly, the grip frame (1210) can move in the first axis direction.

The motor (1280) provides power to enable the guide body (1270) to move along the guide rail (1260).

Since the stacker crane (140) has the structure described above, it can grip the entire transfer tray (130), and can transport the gripped transfer tray (130) in any direction in three dimensions. Accordingly, since the battery cells for activation are not individually transported to the battery cell activator (150), but the entire transfer tray (130) is transported, the problem that occurs when the battery cells are transported individually as in the past can be fundamentally solved. In addition, even if the battery cell activator (150) is stacked and arranged in an m*n form, the stacker crane (140) can easily transport and settle the transfer tray (130) to any battery cell activator (150).

Meanwhile, the stacker crane (140) may have a structure as shown in FIG. 12b and FIG. 14.

FIG. 12b is a perspective view of a stacker crane according to a second embodiment of the present invention.

Referring to FIG. 12b, a stacker crane (140) according to a second embodiment of the present invention has the same configuration as that of the stacker crane (140) according to the first embodiment of the present invention, but includes a gripping portion (1290) instead of a gripping portion (1215) and additionally includes a sensor portion (1295).

The stacker crane (140) also grips the protrusion (1020) of the transport tray (120) using the gripping part (1290). However, unlike the gripping part (1215), the gripping part (1290) operates in a form in which the gripping groove reciprocates along the guide instead of having a hinge structure, and grips the protrusion (1020) of the transport tray (120). The structure and operation of the gripping part (1215) will be described later with reference to FIG. 14.

The sensor unit (1295) is positioned within a preset radius from the gripper unit (1290) to sense the distance between the gripper unit (1290) and the protrusion (1020) of the transport tray (120). The sensor unit (1295) senses the distance between the two to determine whether the gripper unit (1290) has reached a position where it can grip the protrusion (1020). As described below, the length of the gripper groove (1430) in the gripper unit (1290) extended by the gripper groove moving unit (1420) is fixed. Therefore, the sensor unit (1295) determines whether the distance between the two matches the corresponding length (the length to which the gripper groove can be extended). In this case, the gripper groove (1420) extends toward the protrusion (1020) and can grip the protrusion (1020).

FIG. 14a and FIG. 14b are drawings showing an example of operation of a grip frame and a gripping unit according to a second embodiment of the present invention, and FIG. 14c is a drawing showing a gripping unit according to the second embodiment of the present invention gripping a transport tray.

Referring to FIGS. 14a to 14c, the grip part (1290) according to the second embodiment includes a grip home guide (1410), a grip home moving part (1420), and a grip home (1430).

The phage home guide (1410) is implemented on the phage frame (1210) so that the phage home moving part (1420) moves in the short axis direction of the transport tray (130) and moves closer to or further away from the transport tray (130) in the corresponding axis direction. The phage home guide (1410) includes a guide hole that allows the phage home moving part (1420) to flow in and out, so that the phage home moving part (1420) can move as described above.

The phage home moving part (1420) flows within the guide hole of the phage home guide (1410) and is coupled with the phage home (1430) at one end to move the phage home (1430) in the aforementioned direction. Accordingly, the phage home (1430) can move along the phage home guide (1410) by the phage home moving part (1420) to approach the protrusion (1020) of the transport tray (130) or move away from it.

The phage groove (1430) is combined with the transport tray (120), more specifically, the projection (1020), to grasp the transport tray (1020). The phage groove (1430) includes a groove in which the projection (1020) can be seated. The width of the groove (the length in the short axis direction of the transport tray) is implemented to be at least equal to the width of the projection (1020) or greater than the width of the projection (1020). Similarly, the depth of the groove (the length in the direction perpendicular to the short axis direction and the long axis direction of the transport tray) is also implemented to be at least equal to the depth of the projection (1020) or greater than the depth of the projection (1020). Accordingly, the phage groove (1430) can safely seat the projection (1020) within its groove.

Meanwhile, as described above, the grip groove (1430) and the protrusion (1020) are adjusted to be positioned apart by the extendable length of the grip groove moving part (1420) based on the sensing of the sensor (1295). Accordingly, when the grip groove (1430) is extended toward (moved closer to) the protrusion (1020) by the grip groove moving part (1420), the grip groove (1430) settles the protrusion (1020) within its groove and grips it.

FIG. 15 is a perspective view of a battery cell activator according to one embodiment of the present invention, and FIG. 16 is a drawing illustrating a transfer tray mounted on a battery cell activator according to one embodiment of the present invention.

Referring to FIG. 15, a battery cell activator (150) according to one embodiment of the present invention includes a pressurizing member (1510), a jig press plate (1520), a pressurizing plate (1525), a jig plate (1530), a battery cell fixing module (1540), a first rail (1550), a second rail (1555), a frame (1560), a first fixing plate (1564), a second fixing plate (1568), a pressure sensor (1570), a support plate (1580), an elastic member (1585), and a guide cylinder (1590).

The battery cell activator (150) activates battery cells (1060) in a transfer tray (130) that is transferred by a stacker crane (140) and settled on it. As shown in FIG. 6, the frame (1010) of the transfer tray (130) is placed on a pressure member (1510) and a jig press plate (1520), and the battery cells (1060) arranged between the support sheets (1050) in the transfer tray (130) are arranged between the jig plates (1530). That is, the transfer tray (130) is settled by the battery cell activator (150), and an environment in which the battery cells (1060) can be arranged and activated between the jig plates (1530) is formed. In particular, since the restoring member (1070) included in the transfer tray (130) separates the two ends of the frame (1010) and the support sheet support member (1040) from each other, the transfer tray (130) can be installed on the battery cell activator (150) without damage to the battery cell (1060), and activation can proceed smoothly. Accordingly, the battery cell activator (150) can activate the electrical characteristics of the battery cells simply and quickly.

The pressurizing member (1510) receives power from the outside and pressurizes the jig press plate (1520). The pressurizing member (1510) may be implemented as a configuration that receives rotational power, such as a jack screw, and converts it into linear reciprocating motion, or may be implemented as a configuration that receives power and performs linear reciprocating motion.

The jig press plate (1520) receives pressure from the pressurizing member (1510) and applies pressure to each jig plate (1140) and the battery cells arranged between the jig plates. The jig press plate (1520) may include a pressurizing portion (not shown) and a wing portion (not shown).

The jig press plate (1520) is implemented in a rectangular shape with a length that is relatively longer than the height.

The pressurizing member (not shown) is physically connected to the pressurizing member (1510) and receives pressure from the pressurizing member (1510) to pressurize another member.

The wing portion (not shown) is a portion extending in each longitudinal direction from the pressurizing portion (not shown) and disperses the pressure transmitted by the pressurizing member (1510). By dispersing the pressure through the presence of the wing portion (not shown), the jig press plate (1520) can apply uniform pressure to the battery cell positioned between the jig press plate (1520) and the jig plate.

The pressure plate (1525) is placed on the opposite side of the jig press plate (1520) and receives the pressure transmitted through the jig press plate (1520) and the jig plate (1530).

The jig plates (1530) are comprised of one more number of battery cells than the number of battery cells to be activated at one time, and pressurize the battery cells by placing them between them. The jig plates (1530) and the battery cells placed between the jig plates (1530) are illustrated in FIGS. 17 and 18.

FIG. 17 is a perspective view of a jig plate according to one embodiment of the present invention, and FIG. 18 is a side view of a jig plate having a transfer tray mounted thereon according to one embodiment of the present invention.

Referring to FIGS. 17 and 18, a jig plate (1530) according to one embodiment of the present invention includes a jig frame (1710), a guide hole (1714), a rail (1718), a pad (1720), and a pad fixing plate (1730).

The jig frame (1710) provides a space in which other components within the jig plate (1530) are placed or fixed. The jig frame (1710) has a constant area and width (length in the direction in which the pressurizing member applies pressure in FIG. 15) so that each component can be placed and fixed.

Meanwhile, as shown in Fig. 18, when the transfer tray (130) is installed on the battery cell activator (150), the support sheet support member (1040) can be installed on the jig frame (1710). When installed in this manner, the support sheet (1050) and the battery cell (1060) supported by the support sheet (1050) can be placed between the jig frames (1710).

The guide hole (1714) is formed as a through hole in the jig frame (1710) so that the guide cylinder (1590) can pass through the jig plate (1530). As the guide cylinder (1590) passes through the guide hole (1714), the jig plate (1530) moves along the axis (third axis) formed by the cylinder along the guide cylinder (1590).

The rail (1718) is formed along the jig frame (1710) at the lowest end of the jig frame (1710) and moves the battery cell fixing module (1540) coupled to the rail (1718) toward the rail (1718). Since the jig plate (1530) including the jig frame (1710) must pressurize the battery cell mounted thereon, it is arranged to face the first axis and moves along the third axis to pressurize the battery cell. The rail (1718) is formed toward the first axis at the aforementioned position. Accordingly, the battery cell fixing module (1540) coupled to the rail (1718) can move along the rail (1718) along the first axis and move toward or away from the battery cell.

The pad (1720) is placed on a surface facing an adjacent jig plate (1530) within the jig frame (1710) to prevent damage to the battery cell when pressurizing the battery cell. The pad (1720) is made of a material that is elastic or has hardness below a preset standard (not hard) to cushion impact when in contact with the battery cell and prevent damage due to contact.

The pad fixing plate (1730) fixes the pad (1720) to the aforementioned surface of the jig frame (1710). The pad fixing plate (1730) is fixed to the jig frame (1710) by the fixing member (1335). Meanwhile, the pad fixing plate (1730) fixes the pad to one portion (e.g., the center). For example, the pad fixing plate (1730) fixes the pad in various ways, such as including a structure in which a pad can be arranged and coupled to one portion or being engraved in the shape of a pad.

Referring again to FIGS. 15 and 16, the battery cell fixing module (1540) moves on the third axis and the first axis, fixes the battery cell placed between the jig plates (1530), and pressurizes the battery cell. The battery cell fixing module (1540) is included in two pieces and is placed facing each other to fix the battery cell, particularly the electrode within the battery cell, from both sides.

The first rail (1550) is arranged on the third axis on the frame (1560) so that each battery cell fixing module can move closer or further away from each other.

The second rail (1555) is arranged on the first axis at the bottom of the frame (1560) to move each frame (1560) toward or away from each other (the first axis). The second rail (1555) is arranged on the first axis at the bottom of the frame (1560), and the frame (1560) includes a guide part (not shown) at the bottom and is connected to the second rail (1555). Accordingly, the frame (1560) moves along the second rail (1555) on the first axis to move each frame (1560) toward or away from each other.

The frame (1560) supports each battery cell fixing module (1540) and the first rail (1550) and provides a space in which they are arranged. The frames (1560) can be moved closer or further apart from each other along the second rail (1555), and the battery cell fixing modules (1540) can be moved closer or further apart from each other along the rail (1718).

The first fixed plate (1564) fixes the pressurizing member (1510) so that the pressurizing member (1510) can be combined with the jig press plate (1520) without detachment and completely pressurize the jig press plate (1520).

The second fixed plate (1568) fixes the pressure sensor (1570) and maintains a gap between itself and the support plate (1580) at which the pressure sensor (1570) can be placed.

The pressure sensor (1570) senses the pressure applied to the support plate (1580). The pressure sensor (1570) senses the pressure applied to the support plate (1580) between the second fixed plate (1568) and the support plate (1580), and senses the magnitude of the pressure applied to each battery cell. The jig press plate (1520) is pressed by the pressurizing member (1510) and presses each jig plate (1530), and the jig plate (1530) and the battery cells arranged therebetween transmit the pressure to the adjacent jig plate (1530) by the pressurizing and are all compressed toward the support plate (1580). Finally, pressure is transmitted to the support plate (1580) to reduce the gap between the jig plates (1530), and the pressure sensor (1570) senses this.

The elastic member (1585) transmits the pressure transmitted to the pressure plate (1525) to the support plate (1580) while preventing the pressure plate (1525) from being subjected to pressure and colliding with the support plate (1580).

The guide cylinder (1590) is arranged to penetrate the guide hole (1714) of each jig plate (1530) and allows the jig plates (1530) to move along the axis on which the guide cylinder (1590) is arranged. Both ends of the guide cylinder (1590) are fixed to each fixed plate (1164, 1168) and are arranged on the third axis by penetrating the guide hole (1714) of each jig plate (1530). Accordingly, when the jig plate (1530) is pressed by the jig press plate (1520), it can move along the guide cylinder (1590).

The above description is merely an illustrative description of the technical idea of the present embodiment, and those with ordinary skill in the art to which the present embodiment pertains may make various modifications and variations without departing from the essential characteristics of the present embodiment. Therefore, the present embodiments are not intended to limit the technical idea of the present embodiment but to explain it, and the scope of the technical idea of the present embodiment is not limited by these embodiments.
