A plurality of air ejection holes 43b formed in the support surface 43a eject air in a direction perpendicular to the support surface 43a when viewed from the X-axis direction.

When the component is a rectangular parallelepiped, the width of the component alignment section 43 in the Y-axis direction is larger than the length of the shortest side of the component and smaller than the length of the longest side of the component, but is not limited to this. Moreover, when the component is a rectangular parallelepiped, the width of the component alignment section 43 in the Y-axis direction may be smaller than twice the length of the shortest side of the component. Also, the width of the component alignment portion 43 in the Y-axis direction may be determined including the dimensional tolerance of the components.

The support surface of the return transport unit 48 may be, for example, an inclined surface that inclines upward (Z-axis plus direction) from the turning unit 47 toward the component supply position 42 . In other words, the parts may be transported from the turning part 47 to the part supply position 42 at a position higher than the turning part 47 by the return transfer part 48 .

The second conveying portion 40 a 2 includes a return conveying section 48 . The second conveying portion 40a2 opens onto a supporting surface (an example of a third supporting surface) on which the components of the second conveying portion 40a2 are supported, and is configured to be capable of ejecting air upward in a second direction. It can also be said that it has a plurality of air ejection holes (an example of the second air ejection holes).

The side walls 49a and 49c and the partition wall 49b are walls extending in the first direction to form the first conveying portion 40a1 and the second conveying portion 40a2. The side wall 49a and the partition wall 49b form the first conveying portion 40a1, and the partition wall 49b and the side wall 49c form the second conveying portion 40a2. Also, the partition wall 49b functions as a partition that prevents the air jetted from one of the first conveying portion 40a1 and the second conveying portion 40a2 from flowing to the other.

The side walls 49a and 49c and the partition wall 49b may be integrally formed, for example. In other words, no gap need be formed between the first conveying portion 40a1 and the second conveying portion 40a2.

Further, for example, when parts are transported by vibration between the first transport portion 40a1 and the second transport portion 40a2, the vibration conditions are different from each other. A gap is formed between them. As a result, problems such as an increase in the size of the conveying unit in the width direction and parts being caught in gaps may occur.

On the other hand, in the conveying portion 40 according to the present embodiment, as described above, no gap is formed between the first conveying portion 40a1 and the second conveying portion 40a2. 2 can be brought closer to each other, and the width (the length in the Y-axis direction) of the transport section 40 can be reduced. That is, the component supply device 30 can be miniaturized. In addition, it is possible to prevent the component from being caught in the gap. For example, it is possible to smoothly turn the parts in the turning section 47 .

As described above, the transport section 40 has a first transport section 40a1 that transports components in the first direction toward the supply section 50, and is provided along the first transport section 40a1. and a second conveying portion 40a2 for conveying the parts in a second direction opposite to the first direction. An annular path is formed by the first transport portion 40a1 and the second transport portion 40a2.

Note that the first conveying portion 40a1 is not formed in the supply portion 50. As shown in FIG. That is, the length in the first direction of the first conveying portion 40a1 is the total length in the first direction of the component aligning portion 43 and the component rectilinear advancing portion 53 (an example of the length of the aligning portion in the first direction). shorter.

Next, the supply unit 50 will be described further with reference to FIGS. 6A and 6B. FIG. 6A is a sectional view showing the VIa-VIa section shown in FIG. 4(a). FIG. 6B is a perspective view showing the portion of the dashed frame VIb shown in FIG. 4(a). 6A and 6B omit illustration of a plurality of air ejection holes formed in the support surface (bottom surface). Further, in FIG. 6B, illustration of the side wall 54a is omitted.

As shown in FIG. 3, the supply section 50 of the component supply device 30 has a body section 50a and a lid section 50b. The lid portion 50b covers the main body portion 50a and is fixed to the main body portion 50a by a fastening member 38 such as a screw.

As shown in FIGS. 3 and 4, the body portion 50a has a first sensor 51 (see FIG. 2), a component rectilinear portion 53, and side walls 54a and 54b. The first sensor 51 is provided, for example, in the vicinity of the inlet of the component straight advancing section 53 (near the supply section inlet 52), and detects the components passing through the supply section inlet 52. FIG. Sidewalls 54a and 54b are examples of side members.

The parts rectilinear advancing section 53 is connected to the parts aligning section 43, and supplies the parts to the picking-up position by conveying the aligned parts from the conveying section 40 to the picking-up position. The component rectilinear portion 53 is provided extending in the first direction.

As shown in (c) of FIG. 4 , a plurality of air ejection holes 53b are formed in the support surface 53a of the part rectilinear portion 53 . The parts rectilinear advance section 53 sequentially transports a plurality of parts by air ejected from a plurality of air ejection holes 53b. The parts rectilinear advance section 53 can convey a plurality of parts at the same time through a plurality of air ejection holes 53b. 4(c), a part of the air passage for communicating the second air supply portion 63 and the air ejection hole 53b on the positive side of the X axis is illustrated by a dashed line. there is

As shown in FIG. 6A, the component rectilinear portion 53 is a concave groove extending in the first direction. A support surface 53a of the component rectilinear portion 53 is formed by the bottom surface of the groove and supports the component. The support surface 53a is connected to the support surface 43a of the component alignment section 43 and is on the same plane as the support surface 43a. The support surface 53a is formed with a plurality of air ejection holes 53b for floating and conveying the component in the first direction. A plurality of air ejection holes 53b formed in the support surface 53a are formed so as to be able to eject air upward in a first direction. That is, the plurality of air ejection holes 53b formed in the support surface 53a eject air obliquely upward in the first direction when viewed in the Y-axis direction. A plurality of air ejection holes 53b formed in the support surface 53a eject air in a direction perpendicular to the support surface 53a when viewed from the X-axis direction.

When the component is a rectangular parallelepiped, the width (length in the Y-axis direction) of the component rectilinear portion 53 is greater than the length of the shortest side of the component and smaller than the length of the longest side of the component. The width of the component rectilinear portion 53 may be the same as the width of the component alignment portion 43 . As a result, the parts are prevented from coming into contact with the wall surface or the like at the boundary (connection point) between the part rectilinear portion 53 and the part alignment portion 43, which is effective in suppressing blackening of the parts.

The component rectilinear portion 53 has two side walls 54a and 54b arranged to face each other with a gap in the width direction of the support surface 53a. One of the two sidewalls 54a and 54b (the sidewall 54b in the example of FIGS. 6A and 6B) is the other sidewall of the two sidewalls 54a and 54b (the sidewall in the example of FIGS. 6A and 6B). 54a) has a plurality of air ejection holes 54b2 for ejecting air. When the part rectilinear advance portion 53 is a groove, the plurality of air ejection holes 54b2 are formed by one of the mutually facing wall surfaces 54a1 and 54b1 (in the example of FIGS. 6A and 6B, the wall surface 54b1). A plurality of air ejection holes 54b2 are provided along the first direction on the wall surface 54b1. During the period when air is jetted from the plurality of air jet holes 53b of the support surface 53a of the component rectilinear advance portion 53, air is also jetted from the plurality of air jet holes 54b2.

A plurality of air ejection holes 54 b 2 are provided so as to be able to eject air onto the component being floated and conveyed by the component rectilinear advancing portion 53 . The plurality of air ejection holes 54b2 are provided, for example, at a height at which air can be ejected to the component. The pressure or flow rate of air ejected from the air ejection holes 54b2 may be smaller than the pressure or flow rate of air ejected from the air ejection holes 53b. The air ejection hole 54b2 is an example of a third air ejection hole.

In addition, as shown in FIG. 6B , the component rectilinear advance portion 53 has a wall portion 55 at the end of the component rectilinear advance portion 53 in the first direction that contacts the end surface of the component in the first direction. The wall portion 55 abuts on the component to stop the component from being conveyed in the first direction. The wall portion 55 has the function of positioning the component at the take-out position 56 .

The wall portion 55 is formed with suction holes 55a for sucking air. The component is firmly positioned on the wall portion 55 by sucking the first direction side surface of the component conveyed to the take-out position 56 by the suction holes 55a. The part is thereby fixed in the pick-up position. Further, the transportation of the component to the pick-up position 56 may be assisted by air suction through the suction holes 55a. The component may be drawn to the pick-up position 56 by sucking air through the suction holes 55a. In this way, the suction holes 55a may have the function of transporting the component in addition to the function of positioning the component.

For example, the air ejection holes 53b are formed up to the extraction position 56. As shown in FIG. In other words, suction holes for fixing the component cannot be provided at the extraction position on the support surface 53a of the component rectilinear advance portion 53 . Even in such a case, by providing the suction holes 55a in the wall portion 55, the component can be fixed at a desired position without hindering the levitation and transportation of the component.

The suction hole 55a is an example of a suction portion that suctions the end face of the component on the first direction side (the end face on the plus side of the X axis). Note that the adsorption section is not limited to adsorbing a component by air suction, and may be configured to adsorb a component by any of electrostatic force, magnetic force, and adhesive force. Any existing configuration may be used as the configuration for attracting the component by any of electrostatic force, magnetic force, and adhesive force. For example, when a component is attracted by electrostatic force, the attraction section includes one or more electrodes for generating electrostatic force. Then, the control unit 61 may apply a DC voltage to one or more electrodes to cause the component to be attracted (for example, in close contact) to the wall 55 by an electrostatic force between the one or more electrodes and the component.

It should be noted that an aligning section in the component supply device 30 is formed by the component rectilinear advancing section 53 and the component aligning section 43 . The aligning section aligns the components supplied from the case 10 and conveys them to the pick-up position. For example, the plurality of air ejection holes are configured to be capable of ejecting air upward in a first direction from the case 10 toward the removal position 56 on each of the alignment portion and the first inclined surface 44 . The plurality of air ejection holes here includes air ejection holes 43b, 44b and 53b. For example, the air ejection holes 43b and 53b are an example of first air ejection holes, and the air ejection hole 44b is an example of a second air ejection hole. In addition, the component rectilinear advancing portion 53 constitutes a downstream portion of the aligning portion on the take-out position 56 side in the first direction.

Note that the control unit 61 may turn off air suction by the suction holes 55a at the timing when the component is picked up by the mounting head 107 .

FIG. 7 is a block diagram showing the functional configuration of the component supply device 30 according to this embodiment.

As shown in FIG. 7, the component supply device 30 includes, as a functional configuration, the first sensor 51, the second sensor 41, the control section 61, the first air supply section 62, and the and a second air supply portion 63 .

[2. Operation of parts supply device]
Next, the operation of the component supply device 30 configured as described above will be described with reference to FIGS. 8 to 9D. FIG. 8 is a flow chart showing the operation of the component supply device 30 according to this embodiment.

As shown in FIG. 8, the control unit 61 determines whether or not production requiring the operation of the component supply device 30 has started (S10). For example, the control unit 61 may determine that production has started when the mounting system to which the component supply device 30 is attached has started operation, or information indicating that production has started from a higher-level control device. It may be determined that production has started by obtaining

Next, when production is started (Yes in S10), the control section 61 controls the transportation of the parts in the transportation section 40 and the transportation of the parts in the supply section 50 independently of each other (S20). In other words, the control unit 61 does not uniformly control the transportation of components in the transportation unit 40 and the supply unit 50 . In the present embodiment, the control unit 61 controls the air transportation of the components in the transportation unit 40 and the air transportation of the components in the supply unit 50 independently of each other.

Next, the control unit 61 determines whether or not production has ended (S30). For example, the control unit 61 may determine that the production has ended when the operation of the component mounting apparatus to which the component supply device 30 is attached has ended, or the upper control device indicates that the production has ended. By acquiring the information, it may be determined that the production is finished, or when the number of parts detected by the first sensor 51 exceeds a predetermined number, it may be determined that the production is finished.

Next, when the production is completed (Yes in S30), the control unit 61 stops controlling the transportation of the parts in the transportation unit 40 and the transportation of the parts in the supply unit 50 (S40). If not (No in S30), the process returns to step S20 to continue the processing of step S20.

Next, after executing the process of step S40, or when production has not started (No in S10), the control unit 61 ends the operation.

Here, the control of step S20 will be described with reference to FIGS. 9A to 9D. FIG. 9A is a diagram showing a first example of step S20 shown in FIG. FIG. 9A shows the operation in a state where the supply of air in the conveying section 40 is stopped. Air may be supplied to the supply unit 50 during the operation shown in FIG. 9A.

The control unit 61 acquires a detection result indicating whether or not there is a component in the supply unit 50 from the first sensor 51 (S21). For example, the control unit 61 acquires the detection result from the first sensor 51 at predetermined time intervals.

Next, if there is no component in the supply unit 50 based on the detection result (No in S22), the control unit 61 supplies air to the transport unit 40 (S23). It can be said that the control unit 61 starts supplying air to the conveying unit 40, for example, when the result of step S22 is No. Specifically, the control unit 61 controls the first air supply unit 62 and the like to eject air from the air ejection holes of the conveying unit 40 . The control unit 61 controls, for example, air flow in each of the component supply position 42, the component alignment unit 43, the first inclined surface 44, the second inclined surface 45, the turning unit 47, and the return conveying unit 48. Control supply integrally. For example, in step S23, the control section 61 causes air to be jetted from all of the multiple air jetting holes formed in the conveying section 40 .

In this manner, the control section 61 may control the conveyance of components in the conveyance section 40 based on the detection result of the first sensor 51, for example. When the control unit 61 acquires from the first sensor 51 a detection result indicating that there is no component in the supply unit 50 (for example, a detection result indicating that there is no component at a predetermined position in the supply unit 50), 40 is caused to transport the parts.

FIG. 9B is a diagram showing a second example of step S20 shown in FIG.

As shown in FIG. 9B, when production is started (Yes in S10), the control unit 61 supplies air to the supply unit 50 (S24). Specifically, the control unit 61 controls the second air supply unit 63 and the like to eject air from at least the air ejection holes 53b of the supply unit 50 . For example, in step S24, the control section 61 causes air to be ejected from each of the air ejection holes 53b and 54b2. The controller 61 may integrally control the supply of air to each of the air ejection holes 53b and 54b2. In step S24, the controller 61 may cause the suction holes 55a to suck air.

In this manner, the control unit 61 may control the conveyance of components in the supply unit 50 without depending on the detection result of the first sensor 51, for example. For example, when the component mounting apparatus 100 (to be described later) is in operation, the control section 61 may always perform control for supplying components to the pick-up position of the supply section 50 . For example, the control section 61 may perform control to supply air from the second air supply section 63 to the plurality of air ejection holes 53b when the component mounting apparatus 100 is in operation.

FIG. 9C is a diagram showing a third example of step S20 shown in FIG.

As shown in FIG. 9C, the controller 61 may perform steps S25 to S27 in addition to the operations shown in FIG. 9A. If there is no component in the supply unit 50 (No in S22), the control unit 61 supplies air to the supply unit 50 for a predetermined period (S25). For example, when the determination in step S22 is No, the control unit 61 continues supplying air to the supply unit 50 for a predetermined period without causing the transport unit 40 to supply air immediately. At this time, air is not supplied to the conveying section 40 .

Next, the control section 61 acquires the detection result after the air is supplied from the first sensor 51 to the supply section 50 (S26). Based on the detection result obtained in step S26, if there are no parts in the supply unit 50 (No in S27), the control unit 61 supplies air to the transport unit 40 (S23), and if there are parts in the supply unit 50 ( Yes in S27), air is not supplied to the conveying unit 40;

In this manner, for example, when there is no component at a predetermined position in the supply unit 50, the control unit 61 causes the supply unit 50 to carry the component for a predetermined period of time, and after the predetermined period of time, the component is not at the predetermined position. In this case, the transport unit 40 may be caused to transport the components.

As a result, the parts are conveyed by the conveying section 40 only when there is no part by the supplying section 50, so that blackening of the parts due to contact of the parts in the conveying section 40 or the like can be further suppressed.

FIG. 9D is a diagram showing a fourth example of step S20 shown in FIG.

As shown in FIG. 9D, when production is started (Yes in S10), the control section 61 may supply air to the aligning section and the first conveying section 40a1 (S28).

Further, the control unit 61 may perform control to supply components from the case 10 based on the detection result of the second sensor 41, for example. For example, when the control unit 61 acquires from the second sensor 41 a detection result indicating that there is no component in the transport unit 40 (for example, a detection result indicating that there is no component at a predetermined position of the transport unit 40), , parts are supplied to the parts supply position 42 by vibrating the case 10 or the like. Further, for example, when there is no component at a predetermined position on the transport unit 40, the control unit 61 causes the transport unit 40 to transport the component for a predetermined period of time. Since there are no parts in the transport section 40 , the parts may be supplied from the case 10 to the part supply position 42 .

In this way, the control unit 61 controls the conveyance of the parts in the conveying unit 40 based on the detection result of the second sensor 41, and Conveyance of parts may be controlled.

[3. Configuration of Component Mounting Device]
Next, the component mounting apparatus 100 to which the supply unit 80 having the component supply apparatus 30 described above is attached will be described with reference to FIG. FIG. 10 is a diagram showing the configuration of a component mounting apparatus 100 according to this embodiment. An example in which the component mounting apparatus 100 is an apparatus that mounts components on the board 103 will be described. The component mounting apparatus 100 has a function of picking up a component from a component feeder and transferring and mounting the component onto a board 103 . Note that the substrate 103 is an example of an object on which components are mounted.

As shown in FIG. 10, the component mounting apparatus 100 includes a supply unit 80, a base 101, a board transfer mechanism 102, a component mounting mechanism 108 including a mounting head 107, a board recognition camera 109, and a component recognition camera 110. and a power supply unit (not shown).

The substrate transfer mechanism 102 is arranged near the center of the base 101 along the X-axis (the transfer direction of the substrate 103). The substrate transport mechanism 102 transports the substrate 103 carried in from the upstream side in the direction along the X-axis, and positions and holds it on the mounting stage set for executing the component mounting work. The board transfer mechanism 102 is an example of a board holding section that holds the board 103 on which the component held by the mounting head 107 is mounted.

The supply unit 80 is detachably attached to a supply unit attachment section (not shown) of the base 101 which is the main body of the component mounting apparatus 100 . More specifically, the carriage 70 that constitutes the supply unit 80 is attached to the supply unit attachment portion. In this embodiment, the supply unit mounting portions are provided on both sides of the substrate transport mechanism 102 , and the supply units 80 are also arranged on both sides of the substrate transport mechanism 102 . A plurality of feeders 20 can be arranged in parallel along the Y-axis in each supply unit 80, and at least one feeder 20 (bulk feeder) is mounted in parallel. Moreover, by attaching the supply unit 80 to the base 101, each functional unit (for example, the first air supply unit 62 and the second air supply unit 63, etc.) of the supply unit 80 and the power supply unit are electrically connected. , and power is supplied from the power supply unit to each functional unit of the supply unit 80 .

The feeder 20 arranged in the supply unit 80 supplies components to a pick-up position (pick-up position 56 shown in FIG. 6B) by the mounting head 107 of the component mounting mechanism 108 . Note that the mounting head 107 is an example of a head.

An X-axis moving table 105 having a linear drive mechanism is arranged in the X-axis direction at the end in the Y-axis negative direction on the upper surface of the base 101. The X-axis moving table 105 is similarly linearly driven. Two Y-axis moving tables 106 equipped with mechanisms are coupled so as to be movable in the X-axis direction. A mounting head 107 is mounted on each of the two Y-axis moving tables 106 so as to be movable in the Y-axis direction.

The mounting head 107 mounts (mounts) the component held by the feeder 20 arranged in the supply unit 80 on the substrate 103 . The mounting head 107 mounts the component on the board 103 based on the detection result of the third sensor 64, for example.

Mounting head 107 is equipped with component suction nozzles 107a that can suction and hold components and can move up and down individually. The mounting head 107 includes a Z-axis elevating mechanism for elevating the component suction nozzle 107a and a θ-axis rotating mechanism for rotating the component suction nozzle 107a around the nozzle axis. The component suction nozzle 107a is an example of a holding unit that holds a component.

By driving the X-axis moving table 105 and the Y-axis moving table 106, the mounting head 107 moves in the X-axis direction and the Y-axis direction. As a result, the two mounting heads 107 take out the components from the take-out positions of the feeders 20 arranged in the corresponding supply units 80 by the component suction nozzles 107a. A component mounting mechanism 108 is configured by the substrate transport mechanism 102 , the X-axis moving table 105 , the Y-axis moving table 106 and the mounting head 107 . The X-axis movement table 105 and the Y-axis movement table 106 are examples of a driving section that moves the mounting head 107 .

A component recognition camera 110 is arranged between each of the upper and lower carriages 70 and the board transfer mechanism 102 . When the mounting head 107 that has taken out the component from the feeder 20 arranged in the supply unit 80 moves above the component recognition camera 110 , the component recognition camera 110 images the component held by the mounting head 107 . A processing unit (not shown) recognizes and processes the imaging result by image recognition, thereby identifying and detecting the position of the component.

The mounting head 107 is equipped with a board recognition camera 109 which is located on the lower surface side of the Y-axis moving table 106 and moves integrally with the mounting head 107 . As the mounting head 107 moves, the board recognition camera 109 moves above the board 103 positioned by the board transfer mechanism 102 and picks up an image of the board 103 . The position of the substrate 103 is detected by similarly recognizing the imaging result by the image recognition of the processing unit.

The power supply section supplies power to each functional section of the component mounting apparatus 100 . The power supply unit supplies power to, for example, the supply unit 80 arranged in the substrate transport mechanism 102 . Specifically, the power supply section supplies electric power to the first air supply section 62 and the second air supply section 63 of the supply unit 80 and the like. Also, the power supply unit may be connected to an external power supply.

[4. effects, etc.]
A component supply device 30 according to an aspect of the present disclosure supplies components stored in a case 10 (an example of a component storage unit) in a bulk state to an extraction position 56 where a holding unit that holds the components extracts the components. It is a device. The parts supply device 30 includes a parts aligning section 43 and a parts rectilinear advance section 53 (an example of an aligning section) for aligning and conveying the parts supplied from the case 10 to a pick-up position 56 , and and a first conveying portion 40a1 having a first slanted surface 44 that slopes downward toward a component alignment portion 43 and a component rectilinear advance portion 53. As shown in FIG. The parts aligning portion 43, the parts straight advancing portion 53, and the first conveying portion 40a1 are composed of the parts arranging portion 43, the parts straight advancing portion 53, and the first inclined surface 44 on which the parts of the first conveying portion 40a1 are supported. a plurality of air ejection holes 43b, 44b and 53b (an example of first air ejection holes) that open to the have The plurality of air ejection holes 43b, 44b and 53b are arranged in the first direction (X axis positive direction) and upwardly.

For example, when a propulsive force is applied to a part by vibration, the propulsive force is applied in the negative direction of the X axis, the direction of the Y axis, etc. in addition to the positive direction of the X axis. Contact and the like can occur. Also, when aligning the parts by bringing them into contact with an alignment wall (for example, a tapered wall in a plan view), contact between the parts and the wall may occur. That is, when parts are transported using vibration or alignment walls, blackening of the parts can occur during transport of the parts.

On the other hand, in the component supply device 30 according to the present embodiment, the components are conveyed in the first direction (X-axis positive direction) and by the upward air, so that the components are transported in the first direction (X-axis positive direction). Propulsion can be reliably given only by For example, since it is possible to suppress the movement of the parts in the negative direction of the X-axis or the like compared to the case where the propulsive force is applied to the parts by vibration, it is possible to suppress the contact of the parts. In addition, since air is also ejected to the first inclined surface 44, the parts on the first inclined surface 44 are moved to the parts alignment part 43 while suppressing the friction between the parts and the first inclined surface 44. can be moved and aligned. For example, it is possible to prevent the parts from coming into contact with a structure such as a wall, as compared with the case where the parts are aligned using the alignment wall. Therefore, the component supply device 30 according to one aspect of the present disclosure can suppress blackening of the components during transport of the components.

Further, for example, the first conveying portion 40 a 1 may further have a second inclined surface 45 that slopes downward in the opposite direction to the component alignment section 43 and the component rectilinear advance section 53 . The second inclined surface 45 may be provided downstream of the first inclined surface 44 in the first direction.

As a result, it is possible to suppress the clogging of components downstream of the component alignment section 43 and the component rectilinear advance section 53 (for example, the component rectilinear advance section 53).

Further, for example, the component alignment section 43 and the component straight advancing section 53 are arranged with a predetermined gap from the supporting surfaces 43a and 53a (an example of the first supporting surface) on which the components of the component aligning section 43 and the straight straight advancing section 53 are supported. A cover 46 covering a portion of the upper portion may be further provided. The length in the first direction of first conveying portion 40a1 is shorter than the length in the first direction of component aligning portion 43 and component rectilinear advancing portion 53, and cover 46 is located in the first direction of first conveying portion 40a1. may be provided at a position corresponding to the end on the take-out position 56 side.

As a result, when the parts are transported while overlapping each other in the vertical direction, the overlapping of the parts can be released by the cover 46 .

In addition, for example, it is connected to the second inclined surface 45 and is provided along the first conveying portion 40a1 to move the component in a second direction (minus direction of the X-axis) opposite to the first direction. A second conveying portion 40a2 for conveying may be further provided. The second conveying portion 40a2 opens onto a support surface (an example of a third supporting surface) on which the components of the second conveying portion 40a2 are supported, and is configured to be capable of ejecting air upward in a second direction. may have a plurality of air ejection holes (an example of second air ejection holes).

As a result, the parts that have not been conveyed by the parts aligning section 43 and the parts rectilinear advance section 53 can be conveyed by the air even in the second conveying portion 40a2. It can be returned to the upstream side of the component alignment section 43 and the component rectilinear advance section 53 while suppressing the occurrence of friction. Therefore, it is possible to return the component to the upstream side while suppressing blackening of the component.

Further, for example, the downstream portion of the component aligning portion 43 and the component straight advancing portion 53 on the take-out position 56 side in the first direction is the width direction (Y-axis direction) of the support surfaces 43a and 53a of the component aligning portion 43 and the straight component advancing portion 53. ) spaced apart and facing each other (an example of a side member). One side wall 54b of the two side walls 54a and 54b has a plurality of air ejection holes 54b2 (an example of a third air ejection hole) for ejecting air toward the other side wall 54a of the two side walls 54a and 54b. ).

As a result, in the downstream portion of the component alignment portion 43 and the component straight advancing portion 53 (for example, the component straight advancing portion 53), the parts can be brought closer to the side wall 54a (positioned) by the air, so that the components can be moved by the structure such as the wall portion. contact with other objects can be suppressed as compared with the case of moving the side wall 54a. Therefore, the component supply device 30 can bring the components closer to the side wall 54a while suppressing blackening of the components during transport of the components.

Further, for example, the component aligning portion 43 and the component rectilinear advance portion 53 have a wall portion 55 at the terminal end of the component aligning portion 43 and the component rectilinear advance portion 53 in the first direction, the wall portion 55 coming into contact with the end face of the component on the first direction side. , the wall portion 55 may have a suction portion (for example, a suction hole 55a for sucking air) for sucking the end surface of the component.

As a result, even if the support surfaces 43a and 53a (for example, the support surface 53a) are formed with a plurality of air ejection holes and the suction portion cannot be formed on the support surface 53a, the air ejection holes can be formed on the wall portion 55. The component can be fixed at the pick-up position 56 by the sucking portion (for example, the sucking hole 55a).

Further, for example, a suction hole 55a for sucking air is formed in the wall portion 55, and a third sensor 64 (an example of a sensor) for measuring the flow rate or degree of vacuum in the air path connected to the suction hole 55a is further provided. may

Thereby, it is possible to determine whether or not there is a component at the pick-up position 56 based on the flow rate or degree of vacuum in the air path. That is, it is possible to determine whether or not there is a component without contact. Therefore, it is possible to suppress the blackening of the parts as compared with the case where the presence or absence of the parts is determined by a contact sensor.

Further, for example, the component alignment portion 43 and the component rectilinear advance portion 53 may be grooves extending in the first direction.

This allows the grooves to effectively align the parts.

Further, the parts supply method according to one aspect of the present disclosure is a parts supply method in the parts supply device 30 that supplies the parts stored in the case 10 in a bulk state to the pick-up position 56 where the parts are picked up by the holding unit that holds the parts. is. The component supply device 30 is provided along the component aligning unit 43 and the component straight advancing unit 53 for aligning the components supplied from the case 10 and conveying them to the take-out position 56, and along the component aligning unit 43 and the component straight advancing unit 53. A first conveying portion 40 a 1 having a portion 43 and a first inclined surface 44 that slopes downward toward the parts rectilinear advance portion 53 may be provided. In addition, the component aligning portion 43, the component rectilinear advance portion 53, and the first conveying portion 40a1 form a first inclined surface on which the components of the component aligning portion 43, the component rectilinear advance portion 53, and the first conveying portion 40a1 are supported. a plurality of air ejection holes 43b, 44b, and 53b (an example of first air ejection holes) that open to and 44, and are for ejecting air to levitate and convey parts. and 53b. The component supply method is such that air is jetted upward in the first direction toward the take-out position 56 from the case 10 at each of the component alignment portion 43, the component rectilinear advance portion 53, and the first inclined surface 44. may contain.

As a result, the same effect as that of the component supply device 30 described above can be obtained.

Further, the component supply device 30 according to one aspect of the present disclosure is a component supply device that supplies the components stored in the case 10 in a bulk state to the extraction position 56 where the components are extracted by the holding unit that holds the components. The component supply device 30 includes a transport unit 40 that aligns and transports the components supplied from the case 10, and a supply unit that is connected at one end to the transport unit 40 and supplies the components transported from the transport unit 40 to the pickup position 56. 50 , and a control unit 61 that independently controls the transport of components in the transport unit 40 and the transport of components in the supply unit 50 .

As a result, the transport of components in the transport unit 40 and the transport of components in the supply unit 50 are controlled independently of each other. can be suppressed. Therefore, the component supply device 30 according to one aspect of the present disclosure can suppress blackening of the components during transport of the components.

Further, for example, a first sensor 51 (an example of a first detection unit) that detects the amount of components accommodated in the supply unit 50 may be provided. Then, the control section 61 may control the transportation of the component in the transportation section 40 based on the detection result of the first sensor 51 .

As a result, since the conveyance of the parts in the conveying section 40 is controlled according to the amount of the parts in the supply section 50, the conveyance of the parts can be reduced compared to the case where the conveyance section 40 is controlled regardless of the amount of the parts in the supply section 50. The number of transfers or transfer time of parts in the section 40 can be reduced. In other words, since excessive conveyance of the components in the conveying section 40 is suppressed, contact of the components during conveyance in the conveying section 40 can be suppressed. Therefore, the component supply device 30 according to one aspect of the present disclosure can further suppress blackening of the components during transport of the components.

Further, for example, the first sensor 51 detects the presence or absence of a component at a predetermined position of the supply unit 50, and the control unit 61 receives a detection result from the first sensor 51 indicating that there is no component at the predetermined position. When it is obtained, the transport unit 40 may be caused to transport the component.

Accordingly, when there is no component at a predetermined position of the supply unit 50, that is, when the component needs to be transported from the transport unit 40 to the supply unit 50, the transport unit 40 transports the component. In other words, when there is a component at a predetermined position of the supply unit 50, that is, when the component need not be transported from the transport unit 40 to the supply unit 50, the transport unit 40 does not transport the component. Therefore, it is possible to limit the parts to be conveyed by the conveying unit 40 when there is no part at a predetermined position in the supply unit 50, thereby suppressing the blackening of the parts caused by the contact of the parts in the conveying unit 40. can do.

Further, for example, when there is no component at a predetermined position, the control unit 61 further causes the supply unit 50 to convey the component for a predetermined period of time. may be made to transport the parts.

As a result, it is possible to cause the conveying unit 40 to convey the parts only when there is no part reliably at the predetermined position. Therefore, it is possible to further suppress the occurrence of blackening of components in the transport section 40 .

Further, for example, the control unit 61 may control the conveyance of components in the supply unit 50 regardless of the detection result of the first sensor 51 .

Thereby, the supply unit 50 can convey the component under a constant condition regardless of the detection result of the first sensor 51 . Therefore, the supply unit 50 can more reliably supply the components to the pick-up position 56 .

Further, for example, the conveying unit 40 has a plurality of air ejection holes 43b that open in a support surface 43a (an example of a first support surface) that supports the components, and ejects air to float and transport the components. , and the supply unit 50 has a plurality of air ejection holes 53b that open to a support surface 53a (an example of a second support surface) that supports components, and ejects air. It may have a plurality of air ejection holes 53b for levitating and conveying the component. Then, the control section 61 may independently control the air ejected from the plurality of air ejection holes 43b and the air ejected from the plurality of air ejection holes 53b.

As a result, the component is levitated and conveyed, so that friction between the component and the support surfaces 43a and 53a can be suppressed. Further, since the air ejected from the plurality of air ejection holes 43b and the air ejected from the plurality of air ejection holes 53b are controlled independently of each other, compared to the case where the two airs are integrally controlled, either It is possible to perform flexible control such as stopping the supply of one air. By stopping the supply of air, it is possible to suppress the contact of parts in the component. Therefore, the component supply device 30 according to one aspect of the present disclosure can further suppress blackening of the components during transport of the components.

Further, for example, the transport unit 40 is connected to a first transport portion 40a1 that transports components in a first direction from the case 10 to the supply unit 50, and is connected to the first transport portion 40a1. A second transport portion 40a2 may be provided along the portion 40a1 for transporting components from the first transport portion 40a1 in a second direction opposite to the first direction.

As a result, the components that have not been transported from the transporting section 40 to the supplying section 50 can be returned to the upstream side of the transporting section 40 (the minus side of the X axis).

Further, for example, the transport section 40 may further include a component alignment section 43 that is provided along the first transport portion 40a1 and that aligns the components transported in the first direction.

As a result, the components aligned by the component alignment section 43 can be supplied to the supply section 50 .

Further, for example, a second sensor 41 (an example of a second detection section) that detects the amount of components in the first transport portion 40a1 may be further provided. Then, the control section 61 may perform control for supplying components from the case 10 based on the detection result of the second sensor 41 .

As a result, the density of the parts at the position where the parts are supplied from the case 10 is increased, and contact between the parts can be suppressed.

Further, the parts supply method according to one aspect of the present disclosure is a parts supply method of the parts supply device 30 that supplies the parts stored in the case 10 in a bulk state to the pick-up position 56 where the parts are picked up by the holding unit that holds the parts. is. The component supply device 30 includes a transport unit 40 that aligns and transports the components supplied from the case 10, and a supply unit that is connected at one end to the transport unit 40 and supplies the components transported from the transport unit 40 to the pickup position 56. 50. The component supply method may include controlling the component transport in the transport unit 40 and the component transport in the supply unit 50 independently of each other.

As a result, the same effect as that of the component supply device 30 described above can be obtained.

Further, the component mounting apparatus 100 according to one aspect of the present disclosure includes the component supply device 30 described above, the mounting head 107 (an example of a head) for holding the component supplied by the component supply device 30, and the mounting head 107 and a Y-axis moving table 106 (an example of a driving unit), and a substrate transport mechanism 102 (a part of the substrate holding unit) that holds the substrate 103 on which the components held by the mounting head 107 are mounted. example).

As a result, the component mounting apparatus 100 can mount on the substrate 103 a component whose blackening is suppressed.
