Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that in order to better illustrate the contents of the drawings, some of the drawings are turned 90 ° to the left for reading; however, when directions such as "left", "right", "up", "down", etc. are described in the drawings, the directions of the numerals in the drawings are used as the standard; that is, when the reference numerals are set to the left in the drawing, the orientation is based on the case where the drawing is turned 90 ° to the right.

First, referring to fig. 5, there is illustrated a thermal press mechanism 30 including: the hot-pressing table 31 is used for receiving the battery cell 1; a hot press plate 32 provided opposite to the hot press table 31; and a hot pressing driving part 33 for driving the hot pressing table 31 and the hot pressing plate 32 to move relatively, so as to press or loosen the battery cell 1.

In the figure, the hot pressing table 31 and the hot pressing plate 32 are arranged oppositely in the vertical direction, the hot pressing table 31 arranged below is used for receiving the built battery cell 1, and the hot pressing plate 32 arranged above is connected with the hot pressing driving member 33. The cell 1 is in place, and the hot pressing driving part 33 drives the hot pressing plate 32 to move towards the hot pressing table 31, so as to clamp the cell 1 between the hot pressing table 31 and the hot pressing plate 32. Heating elements (such as resistors, heating rods and the like) are arranged in the hot pressing table 31 and the hot pressing plate 32, the heating elements work, heat is applied to the battery cell 1 through the hot pressing table 31 and the hot pressing plate 32, and finally the battery cell 1 is shaped and activated. After the hot pressing, the hot pressing driving member 33 drives the hot pressing plate 32 to move away from the hot pressing table 31 to loosen the cell 1, so that the cell 1 can be taken away by a blanking mechanism (not shown).

The hot pressing table 31 and the hot pressing plate 32 may be block structures with flat surfaces or block structures with grooves on the surfaces according to the surface treatment requirement of the battery core 1. The hot press driving unit 33 may be a driving member such as an air cylinder or an electric cylinder. The blanking mechanism can adopt clamping jaws, sucking discs and the like to extract and carry components.

In other embodiments, the hot pressing driving member 33 may be connected to the hot pressing stage 31 to drive the hot pressing stage 31 to move closer to or away from the hot pressing plate 32. Alternatively, the hot press driving member 33 may include two sets of the hot press stage 31 and the hot press plate 32, which are connected to each other, respectively, and thereby drive them to approach or separate from each other.

Further, the heat pressing stage 31 has an anti-sticking layer 10 thereon. The anti-sticking layer 10 is used to separate the battery cell 1 from the hot-pressing stage 31, thereby preventing the battery cell 1 from sticking to the hot-pressing stage 31. Antiseized layer 10 can cover partial hot pressing platform 31 at least, when accepting electric core 1, avoid electric core 1 direct contact hot pressing platform 31 surface.

When the anti-sticking layer 10 is used, the anti-sticking layer needs to be tensioned so as to avoid the phenomenon that the surface of the anti-sticking layer is wrinkled to influence the surface quality of the electric core 1 after hot pressing; meanwhile, the anti-sticking layer 10 is prevented from being deformed and affecting the feeding and discharging of the battery cell 1 under the influence of external force. In addition, make antiseized layer 10 laminating hot pressing platform 31 surface, can ensure that hot pressing platform 31 accurately does work to electric core 1 to further guarantee the stable state of antiseized layer 10, avoid antiseized layer 10 shake, displacement or deformation.

The release layer 10 may be made of a release material, or the surface of the release layer that receives the battery cell 1 may be coated with a release material. The release material may be ceramic, Teflon, PET, etc. In order to prevent the thickness of the anti-adhesion layer 10 from affecting the heat transfer, the anti-adhesion layer 10 may be provided in a sheet shape.

For convenient dress anti-adhesion layer 10 of tearing open, this application provides an anti-adhesion layer quick change mechanism, anti-adhesion layer 10 sets up on hot pressing platform 31 through anti-adhesion layer quick change mechanism.

Antiseized layer quick change mechanism includes: at least one detachment assembly 20; the detachment assembly 20 includes: a supporting plate 21 for receiving the first side edge of the anti-sticking layer 10; the lug 22 is arranged on the supporting plate 21; a fixing frame 23 fixedly arranged on one side of the hot pressing table 31; the elastic piece 24 is arranged between the supporting plate 21 and the fixed frame 23; wherein, the first side edge is provided with a mounting hole 11; when the anti-sticking layer 10 is installed, the bump 22 penetrates into the installation hole 11, the internal force of the anti-sticking layer 10 interacts with the elastic force of the elastic element 24, the elastic element 24 deforms, and the anti-sticking layer 10 is tensioned; when the anti-sticking layer 10 is detached, the bump 22 is made to penetrate through the mounting hole 11, so that the anti-sticking layer 10 can be removed easily.

Depending on the size of the anti-adhesion layer 10 and the position of the anti-adhesion layer 10 on the hot press table 31, the detaching unit 20 may be provided on the hot press table 31, on the side of the hot press table 31, or outside the hot press table 31, as long as the anti-adhesion layer 10 can be connected and the anti-adhesion layer 10 can be tightened to be attached to the surface of the hot press table 31.

For this reason, it is necessary to ensure that the connection position of the bump 22 and the supporting plate 21 is not higher than the surface of the heat pressing table 31 for receiving the battery cell 1. Thus, the anti-sticking layer 10 is sleeved on the bump 22 through the mounting hole 11, and after the first side edge of the anti-sticking layer 10 moves to the lowest position along the bump 22 and contacts the supporting plate 21, the anti-sticking layer 10 can be tightly attached to the hot-pressing table 31.

In order to prevent the arrangement of the detaching unit 20 from affecting the structure of the heat pressing stage 31, one side (i.e., the first side) of the anti-adhesion layer 10 may protrude from the heat pressing stage 31. At this time, the detaching unit 20 is disposed outside the heat pressing stage 31 to be connected to the side of the release layer 10 from which it protrudes.

Wherein the first side edge can be either side of the release layer 10. For example, in the embodiment shown in fig. 1, 2 or 4, the release layer 10 has a regular quadrilateral shape overall, and the first side is the left side of the release layer 10. The other side opposite the first side is a second side, e.g., the second side is a right side in the embodiments shown in fig. 1, 2, or 4.

It will be readily appreciated that to tension the release layer 10, it is at least necessary to move the opposing side edges of the release layer 10 away from each other until the release layer 10 is flattened.

In one embodiment, when the first side of the release layer 10 is attached to the detachment assembly 20, the second side may be fixedly disposed on the heat pressing stage 31. For example, the second side may be bonded to the hot press table 31, may be fastened to the hot press table 31 by a fastener such as a screw, or may be fixed to the hot press table 31 by a member capable of picking up the anti-sticking layer 10 such as a jig or a suction cup. So, antiseized layer 10 of second side relatively fixed through shirking subassembly 20 reverse tension first side for the second side is kept away from to first side, can be convenient, accurately tensioning antiseized layer 10.

To achieve the reverse stretch of the detachment assembly 20, the elastic member 24 is deformed such that the elastic force or pulling force generated by the elastic member for restoring the original shape is in the same direction as the direction required for tensioning the release layer 10 (i.e., the first side is away from the second side). For example, referring to fig. 2, the second side of the release layer 10 is fixed to the right side of the hot pressing stage 31, and the first side protrudes outward from the left side of the hot pressing stage 31 and is connected to the detaching assembly 20; at this time, the fixing frame 23 is arranged at the left side of the first side; after the first side edge is sleeved in the bump 22, the elastic element 24 is stretched under the influence of the internal force of the anti-sticking layer 10; the elastic members 24 have a tendency to contract, which creates a pulling force that pulls the first side edge to the left, thereby tensioning the release layer 10.

For another example, referring to fig. 3, the second side of the release layer 10 is fixed to the right side of the hot pressing stage 31, and the first side protrudes outward from the left side of the hot pressing stage 31 and is connected to the detaching assembly 20; at this time, the fixing frame 23 is arranged at the right side of the first side; after the first side edge is sleeved in the bump 22, the elastic element 24 is compressed under the influence of the internal force of the anti-sticking layer 10; at this time, the elastic member 24 has a tendency to bounce, and the elastic force generated by it stretches the first side edge leftward, thereby tensioning the release layer 10.

It is contemplated that the protrusions 22 may be regular blocks (e.g., cylinders, cubes, cuboids, etc.) to facilitate movement of the mounting holes 11 along the protrusions 22, contact the retainer 21, or move away from the protrusions 22. Correspondingly, the mounting hole 11 may be a through hole with a uniform shape and aperture corresponding to the bump 22. At this time, in order to facilitate the insertion of the projection 22 into the mounting hole 11, the mounting hole 11 may be larger than a cross-sectional area of the insertion end of the projection 22. In this case, when the hot pressing table 31 moves and/or the battery cell 1 is loaded or unloaded, the mounting hole 11 is easily separated from the bump 22, so that the anti-sticking layer 10 is displaced or separated, which affects the normal use of the hot pressing mechanism 30.

To this end, in one embodiment, the mounting hole 11 includes a hole a and a hole B in communication, the hole a being larger than the hole B; the projection 22 comprises a first portion and a second portion, the first portion being disposed on the second portion, the second portion being disposed on the pallet 21; the first part is able to move in hole a but cannot enter hole B; the second part is movable in the hole B; securing the release layer 10 such that the first portion passes through the aperture a and the second portion is ultimately defined by the aperture B as the release layer 10 is tensioned; when the release layer 10 is removed, the carrier plate 21 is pushed towards the aperture a so that the projections 22 pass out of the aperture a.

Wherein, hole B is the aperture of keeping away from the second side, and along with antiseized layer 10 is by the tensioning gradually, the first side is kept away from the second side gradually, and the lug 22 of inserting mounting hole 11 moves from hole A to hole B until the edge of hole B and lug 22 interact.

Since the first portion of the bump 22 cannot pass through the hole B, even if the anti-adhesion layer 10 moves upward under the influence of an external force after the bump 22 enters the hole B, the bump 22 is blocked by the first portion, thereby preventing the anti-adhesion layer 10 from being separated from the detaching assembly 20. When the anti-sticking layer 10 needs to be detached, the supporting plate 21 or the bump 22 is pushed towards the hole A, so that the first part is aligned with the hole A, and the anti-sticking layer 10 can be conveniently taken down.

For example, in the embodiment shown in fig. 1 or 3, hole B is to the left of hole a. When the device is installed, the first side edge is pulled leftwards, and the supporting plate 21 or the lug 22 is pulled rightwards, so that the hole A is opposite to the first part; the anti-sticking layer 10 is sleeved on the bump 22, and the first part can pass through the hole A; the first side edge falls on the pallet 21; the second part is in the mounting hole 11; as the elastic force of the elastic member 24 interacts with the internal force of the anti-adhesion layer 10, the second portion enters the hole B and abuts against the left side edge of the hole B; when the elastic member 24 reaches the equilibrium state, the release layer 10 is tensioned.

In one embodiment, the protrusion 22 may be a screw, including a nut and a threaded rod; it will be appreciated that the nut is a first, structurally larger part which is disposed above, while the screw is a second, structurally smaller part which is disposed below, and which connects the support plate 21. Correspondingly, a threaded hole is formed in the supporting plate 21, a screw is in threaded connection with the threaded hole, and the distance of the movement of the mounting hole 11 on the bump 22 can be adjusted after the anti-sticking layer 10 is tensioned by controlling the depth of the screw screwed into the threaded hole. For example, after the anti-adhesion layer 10 is tensioned, the screw can be screwed in continuously until the nut is pressed against the supporting plate 21; at this moment, nut cooperation layer board 21 can compress tightly antiseized layer 10 to avoid antiseized layer 10 to follow the motion of lug 22, guarantee that antiseized layer 10 hugs closely hot pressing platform 31 all the time.

Because the elastic force direction of the elastic element 24 is uncertain, in order to avoid that the anti-sticking layer 10 is driven to deviate from the preset position when the elastic element 24 deforms, the detaching assembly 20 further comprises a guide element 25 which is fixedly arranged on the fixed frame 23 and arranged along the tensioning direction; the supporting plate 21 is slidably disposed on the guide 25 and can move along the guide 25 toward or away from the fixing frame 23.

Wherein, the tensioning direction is the direction that the first side edge is close to or far away from the second side edge. The guide 25 may be a guide member such as a guide rod or a guide rail.

In one embodiment, referring to fig. 1, 2, 3 or 4, the guide 25 is disposed in a left-right direction to guide the first side edge away from the second side edge rapidly during tensioning of the release layer 10.

In one embodiment, the elastic member 24 is a spring, and the guide member 25 is a guide rod; the spring is sleeved on the guide rod, one end of the spring is connected with the supporting plate 21, and the other end of the spring is connected with the fixing frame 23. Referring to fig. 1 or fig. 3, the left end of the guide rod is fixed on the fixing frame 23, and the right end of the guide rod passes through the supporting plate 21 and protrudes out of the right side of the supporting plate 21; the pallet 21 is slidably arranged on the guide 25 by means of linear bearings. Because the spring sleeve is on the guide arm, the guide arm can be injectd the deformation direction of spring. When the anti-sticking layer 10 is tensioned, the right end of the spring is pulled away by the support plate 21 and has a tendency to move to the left.

Further, in order to ensure that the anti-sticking layer 10 is tensioned everywhere, a plurality of bumps 22 are arranged on the supporting plate 21 at intervals along the extending direction of the first side edge, a plurality of mounting holes 11 are formed in the first side edge, and the mounting holes 11 correspond to the bumps 22 one by one. Referring to fig. 1, 2, 3 or 4, the first side edge extends in the up-down direction and has a certain length; three mounting holes 11 are formed in the first side edge at intervals, one of the mounting holes is close to the upper corner of the first side edge, the other mounting hole is close to the lower corner of the first side edge, and the last mounting hole is located in the middle of the first side edge, so that the fact that all parts of the first side edge are tensioned is guaranteed.

In another embodiment, the anti-adhesion layer quick-change mechanism comprises two detachment assemblies 20, and the two detachment assemblies 20 are oppositely arranged and respectively act on the first side edge and the second side edge of the anti-adhesion layer 10. Through setting up two and shirking the subassembly 20, single operating personnel during operation no matter be in which position, can both shirk and change the antiseized layer 10 nearby, further convenient processing. In addition, through two take-off assemblies 20, can stretch anti-sticking layer 10 from two directions, ensure that anti-sticking layer 10 is by the tensioning to further guarantee that anti-sticking layer 10 opposite both sides atress is balanced.

Referring to fig. 4, a detachment assembly 20 is disposed at the left side of the hot-pressing station 31, and a first side of the anti-sticking layer 10 is connected to the detachment assembly; the other detaching unit 20 and the second side edge to which the anti-sticking layer 10 is attached are provided on the right side of the hot press table 31. The two detachment assemblies 20 are arranged in mirror image, so that the detachment assembly 20 on the left side stretches the first side edge leftwards, and the detachment assembly 20 on the right side stretches the second side edge rightwards, so that the anti-sticking layer 10 is tensioned, and the anti-sticking layer 10 is tightly attached to the hot-pressing table 31.

In other embodiments, multiple or even all of the side edges of the release layer 10 may be attached to a single release member 20.

Further, in order to limit the position of the battery cell 1 on the hot pressing table 31 and ensure that the hot pressing table 31 and the hot pressing plate 32 are accurately hot-pressed, the hot pressing mechanism 30 further includes a limiting component, and the limiting component includes a first limiting plate 34 and a second limiting plate 35 which are oppositely disposed on two sides of the hot pressing table 31, and is used for limiting the position of the battery cell 1 placed in the hot pressing table 31.

The first and

second stopper plates

34 and 35 may be provided on the hot press stage 31, or may be provided outside the hot press stage 31 and extend toward a position where the hot press stage 31 receives the cell 1. When the battery core 1 is loaded, the battery core 1 is placed between the first limiting plate 34 and the second limiting plate 35; on one hand, the first limiting plate 34 and the second limiting plate 35 can abut against two sides of the battery cell 1, so that the battery cell 1 is fixed and the displacement of the battery cell 1 in the hot pressing process is avoided; on the other hand, the first limiting plate 34 and the second limiting plate 35 can limit the feeding position of the battery cell 1, and other mechanisms are guaranteed to accurately act on the battery cell 1.

In an embodiment, referring to fig. 4 or 5, the first limiting plate 34 and the second limiting plate 35 are respectively disposed on the fixing frame 23 of the set of detachment assemblies 20, and the limiting portion for contacting the battery cell 1 is located above the anti-adhesion layer 10 and directed to the hot-pressing stage 31. For this purpose, the anti-sticking layer 10 is correspondingly notched so that the first and second limiting

plates

34 and 35 contact the fixing frame 23.

Furthermore, the first limit plate 34 and the corresponding fixing frame 23 are respectively provided with a waist-shaped hole and a threaded hole which are matched with each other, and the waist-shaped hole points to the second limit plate 35; through the exposed position of adjustment screw hole in waist type hole, can adjust the interval of first limiting plate 34 and second limiting plate 35, when guaranteeing first limiting plate 34 and second limiting plate 35 accuracy and injecing electric core 1 position, can also improve equipment's suitability. And/or, waist-shaped holes and threaded holes which are matched with each other are respectively formed in the second limiting plate 35 and the corresponding fixing frame 23, and the setting conditions of the second limiting plate and the first limiting plate 34 are similar, and are not repeated here.

Further, the hot-press mechanism 30 further includes a first test board 36 and a second test board 37 which are oppositely disposed, and can respectively contact the tab on one side of the electric core 1, so as to perform a voltage withstand insulation test on the electric core 1.

Referring to fig. 4, the cell 1 main body is a substantially long hair body, and tabs are projected on the side faces constituted by the width and height thereof. When the voltage-resistant insulation test is carried out, the test plate is required to be connected with the lug and input test voltage to the electric core 1, so that the electric leakage condition of the electric core 1 is tested.

When the hot-press mechanism 30 includes the limiting plates (the first limiting plate 34 and the second limiting plate 35) and the testing plates (the first testing plate 36 and the second testing plate 37), the limiting plates are used to limit two sides of the battery cell 1 where no tab is disposed, and the testing plates are used to contact two sides of the battery cell 1 where a tab is disposed. For example, in the embodiment shown in fig. 4, the first and

second test plates

36 and 37 are disposed on the upper and lower sides of the hot press stage 31, and the first and second stopper plates 34 and 3 are disposed on the left and right sides of the hot press stage 31. During feeding, two sides of the battery cell 1 without the tabs are opposite to the limiting plates, and finally the battery cell 1 is placed between the first limiting plate 34 and the second limiting plate 35; at this moment, first limiting plate 34 and second limiting plate 35 not only can inject the position of electric core 1 on hot pressing platform 31, can also inject the state of electric core 1 for the both sides that electric core 1 does not possess the utmost point ear on hot pressing platform 31 just survey test panel 36 and second to the first test panel 37, so that two test panels of utmost point ear contact, finally realize hot pressing and withstand voltage insulation test.
