Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a component mounting system, a feeder cart, and a component supplying method that picks up components supplied from a tape feeder and mounts them on a board. [Background technology]
[0002] A component mounting system is comprised of a component supply unit with a part feeder that supplies components, and a component mounting unit with a mounting head that picks up the components supplied by the part feeder and mounts them on a board. Tape feeders that use component supply tape are often used as part feeders. The component supply tape is configured to have a cover tape attached to a carrier tape that stores components in pockets, and the tape feeder is configured to pull the component supply tape supplied from a reel through a tape inlet and transport it using a sprocket. The cover tape of the transported component supply tape is peeled off just before it reaches the component removal position, allowing the mounting head to pick up the components at the component removal position (see, for example, Patent Document 1 below). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] International Publication No. 2017 / 056262 Summary of the Invention [Problem to be solved by the invention]
[0004] In the tape feeder, components are usually movable within pockets. However, if a component in a pocket becomes charged with static electricity or the like and sticks to the cover tape, the component may fly out of the pocket when the cover tape is peeled off, leaving the pocket empty and preventing the mounting head from picking up a component from the pocket positioned at the component pick-up position.
[0005] Therefore, the present disclosure aims to provide a component mounting system, a feeder cart, and a component supply method that allows the mounting head to reliably pick up components at the component removal position even if the components are stuck to the cover tape within the pocket of the component supply tape. [Means for solving the problem]
[0006] The component mounting system of the present disclosure is a component mounting system comprising: a component mounting unit that picks up components using a mounting head and mounts them on a substrate; and a component supply unit that supplies components to the component mounting unit. The component supply unit comprises: a tape feeder that supplies components to a component removal position by drawing in and transporting a component supply tape, which is composed of a carrier tape with components stored in pockets and a cover tape attached thereto, from a tape inlet; and a vibration application unit that applies vibration to a portion of the component supply tape drawn into the tape feeder before it reaches the tape inlet.
[0007] The feeder cart disclosed herein is a feeder cart equipped with a tape feeder that supplies components to a component removal position by pulling in and transporting a component supply tape, which is made up of a carrier tape with components stored in a pocket and a cover tape attached thereto, from a tape inlet, and is equipped with a vibration application unit that applies vibration to the portion of the component supply tape that is pulled into the tape feeder before it reaches the tape inlet.
[0008] The component supply method disclosed herein is a component supply method using a tape feeder that supplies components to a component removal position by pulling in and transporting a component supply tape composed of a carrier tape with a cover tape attached to it that stores components in a pocket from a tape inlet, and by applying vibration to the part of the component supply tape that is pulled into the tape feeder before it reaches the tape inlet, components that were attached to the cover tape in the pocket are separated from the cover tape. [Effects of the Invention]
[0009] According to the present disclosure, a component mounting system, a feeder cart, and a component supply method are provided that enable a mounting head to reliably pick up a component at a component removal position even if the component is stuck to a cover tape within a pocket of the component supply tape.

DETAILED DESCRIPTION OF THE INVENTION
[0011] Hereinafter, with reference to the drawings as appropriate, detailed descriptions of each embodiment that specifically disclose the configuration and operation of a printing device according to the present disclosure will be provided. However, unnecessary detailed descriptions may be omitted. For example, detailed descriptions of well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure and are not intended to limit the subject matter recited in the claims.
[0012] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Figures 1 and 2 show a component mounting system 1 according to an embodiment of the present disclosure. The component mounting system 1 has the function of mounting components BH on a board KB delivered from outside and delivering the board, and is configured with a component mounting unit 2 and a component supply unit 3. In this embodiment, the left-right direction as seen from the operator OP is defined as the X direction, the front-rear direction as seen from the operator OP (the horizontal direction perpendicular to the X direction) is defined as the Y direction, and the up-down direction is defined as the Z direction.
[0013] Fig. 1 is a perspective view of a portion of a component mounting system according to an embodiment of the present disclosure, and Fig. 2 is a side view of the component mounting system according to an embodiment of the present disclosure.
[0014] 1 and 2, the component mounting unit 2 is provided with a board transport unit 12 consisting of a pair of conveyor mechanisms mounted on a base 11. The board transport unit 12 transports the board KB in the X direction and positions it at a predetermined working position. A mounting head 13 is provided above the base 11. The mounting head 13 is moved horizontally by a head movement mechanism 14 consisting of, for example, an XY movement mechanism. The mounting head 13 is provided with a plurality of nozzles 13N extending downward. The mounting head 13 can generate a vacuum suction force at the bottom end of each nozzle 13N.
[0015] 1 and 2, the component supply unit 3 includes a plurality of tape feeders 21 that supply components BH to the mounting head 13, and a feeder cart 22 that holds these plurality of tape feeders 21. Each tape feeder 21 transports a component supply tape BT that stores components BH, and supplies the components BH to a component take-out position 21T that is set at the end on the far side (the side closer to the board transport unit 12, considered the downstream side) as seen from the operator OP. The feeder cart 22 is a cart on which the tape feeders 21 are mounted, and is moved along the floor surface FL and connected to the base 11 of the component mounting unit 2.
[0016] When the component mounting system 1 performs a component mounting operation to mount components BH on a board KB, the board transport unit 12 first operates to carry in the board KB supplied from outside the component mounting unit 2 and position it at a predetermined work position. Once the board KB has been positioned, each tape feeder 21 operates to supply components BH to each component removal position 21T. The mounting head 13 is moved back and forth between the tape feeders 21 and the board KB by the head moving mechanism 14, repeatedly performing the component mounting operation.
[0017] In one component mounting operation, the mounting head 13 uses the nozzle 13N to pick up and suck up a component BH supplied by the tape feeder 21, and then mounts the component BH at a predetermined target component mounting position on the board KB. When the mounting head 13 repeats the component mounting operation and all of the components BH to be mounted on the board KB have been mounted, the board transport unit 12 operates to transport the board KB out of the component mounting unit 2.
[0018] In the component mounting system 1 configured as above, the present embodiment is characterized by the configuration of the component supply unit 3, which will be described below. In Figures 1 and 2, a block-shaped feeder base 31 is provided on the top of the feeder cart 22, and the tape feeder 21 is detachably attached to the top surface of the feeder base 31. A plurality of tape feeders 21 can be attached to the feeder base 31 and lined up in the X direction. Below the feeder base 31, reel holders 32 are provided in two tiers, upper and lower. Each reel holder 32 holds a plurality of reels RL lined up in the X direction, and a component supply tape BT is wound around each reel RL.
[0019] FIG. 3 is a perspective view showing a component supply tape, together with a reel, used in the component mounting system according to the embodiment of the present disclosure.
[0020] In Figure 3, the component supply tape BT is composed of a carrier tape CT and a cover tape TT. The carrier tape CT has pockets PK that open upward and are arranged in a row at equal intervals along the length, and each pocket PK stores one component BH. The cover tape TT is attached to the top surface of the carrier tape CT, so that the components BH in the pockets PK are sealed within the pocket PK. A number of feed holes KH are arranged in a row at equal intervals in a position parallel to the row of pockets PK on the carrier tape CT.
[0021] 3, the tip of the cover tape TT is processed so that it extends a certain length beyond the tip of the carrier tape CT. Hereinafter, the portion of the cover tape TT extending from the tip of the carrier tape CT will be referred to as the "extension ES" of the cover tape TT.
[0022] FIG. 4 is a side view of a tape feeder provided in the component mounting system according to the embodiment of the present disclosure.
[0023] 4, tape feeder 21 is configured with a main body 41 as a base, which is detachably attached to feeder base 31. Inside main body 41, a transport path 42, which is a passage for transporting component supply tape BT, is formed. A tape inlet 42A is provided on the end face of main body 41 on the front side (upstream side) as seen from operator OP, into which component supply tape BT pulled out from reel RL is inserted.
[0024] A tape outlet 42B is provided at the downstream end face of the main body 41 as seen from the operator OP, from which the component supply tape BT (more specifically, the carrier tape CT from which the cover tape TT has been peeled off) that has traveled through the transport path 42 is discharged. The component removal position 21T described above is set at a downstream position above the main body 41.
[0025] 4, two sprockets 43 (upstream sprocket 43A and downstream sprocket 43B) serving as a tape transport unit, a transport unit drive motor 44 serving as a tape transport unit drive unit, and a feeder control unit 45 (FIG. 4) are provided within main body 41. Transport unit drive motor 44 is controlled by feeder control unit 45, and drives the two sprockets 43 to rotate synchronously in the same direction (arrow A shown in FIG. 5; FIG. 5 is an enlarged view of area RY shown in FIG. 4).
[0026] Each of the two sprockets 43 rotates with the feed pins 43P on the outer periphery engaged with the feed holes KH of the component supply tape BT in the conveying path 42. This causes the component supply tape BT to advance downstream in the conveying path 42. When the sprockets 43 rotate and pull the component supply tape BT into the main body 41, that amount of the component supply tape BT is pulled out from the reel RL, and the reel RL is pulled by the pulled-out component supply tape BT and rotates (rotates in place) within the reel holder 32.
[0027] As shown in Figures 1 and 2, two component supply tapes BT are inserted into tape inlet 42A of tape feeder 21, each pulled out from two upper and lower reel holders 32 provided on feeder cart 22. The component supply tape BT pulled in and transported by tape feeder 21 is the component supply tape BT pulled out from the upper reel RL, and will be referred to as the "current tape BT1" hereinafter. The component supply tape BT pulled out from the lower reel RL is a replenishment component supply tape BT that is transported after current tape BT1 has been transported to its terminal end and the current tape BT1 runs out of components, and will be referred to as the "next tape BT2" hereinafter (Figure 2).
[0028] FIG. 5 is a side view of a portion of a tape feeder included in the component mounting system according to the embodiment of the present disclosure.
[0029] 4 and 5, a tape cover 46 is provided on the upper part of the main body 41. The tape cover 46 covers part of the component supply tape BT (current tape BT1) conveyed on the conveying path 42 from above.
[0030] 4 and 5, a component removal opening 46K is provided near the downstream end of the tape cover 46. The component removal opening 46K is located above the component removal position 21T. A cover tape pull-out opening 46H is provided in the tape cover 46 at a position upstream of the component removal opening 46K (FIGS. 5 and 6(a) and 6(b)). The cover tape pull-out opening 46H is a slit-shaped opening extending in the width direction (X direction) of the tape cover 46 for pulling out the cover tape TT peeled off from the carrier tape CT upward.
[0031] 6(a) and 6(b) are explanatory diagrams illustrating the operation of a cover tape retracting section provided in a tape feeder provided in a component mounting system according to an embodiment of the present disclosure.
[0032] 4, 5, 6(a) and 6(b), an air blowing unit 47 is provided inside the main body 41. The air blowing unit 47 is provided below the cover tape pull-out opening 46H. The air blowing unit 47 is controlled by the feeder control unit 45 to operate and blows positive pressure air AR from below to above (into) the conveying path 42 (FIG. 6(a)).
[0033] 4, 5, and 6(a) and (b), a cover tape retraction section 48 is provided above the air ejection section 47 inside the main body section 41. The cover tape retraction section 48 is composed of a drive roller 48a and two driven rollers 48b. The two driven rollers 48b are in contact with the drive roller 48a and rotate in the opposite direction to the drive roller 48a. The drive roller 48a is driven by the rotational power of the two sprockets 43 transmitted via a gear mechanism (not shown).
[0034] 4, a conveyance detection unit 49 is provided near the middle position of the conveyance path 42 inside the main body 41. The conveyance detection unit 49 projects and receives inspection light (not shown) at a predetermined position inside the conveyance path 42, and detects whether the component supply tape BT is progressing inside the conveyance path 42, i.e., whether the tape feeder 21 is conveying the component supply tape BT, by detecting a state in which the inspection light is turned on and off at regular intervals by the components BH.
[0035] When causing the tape feeder 21 configured as described above to perform the supply operation of components BH, the operator first inserts the leading end of the component supply tape BT, which has the extension portion ES formed on the cover tape TT, from the tape inlet 42A into the conveying path 42. The leading end of the component supply tape BT inserted into the conveying path 42 is first conveyed downstream by the upstream sprocket 43A, and then handed over to the downstream sprocket 43B for further conveyance downstream.
[0036] As shown in Fig. 5, the cover tape pull-out opening 46H and the air jetting unit 47 are located between the positions where the leading end of the component supply tape BT is transferred from the upstream sprocket 43A to the downstream sprocket 43B. When the extension ES of the cover tape TT approaches the cover tape pull-out opening 46H, the air jetting unit 47 is controlled by the feeder control unit 45 to jet positive pressure air AR (Fig. 6(a)). As a result, the extension ES of the cover tape TT is blown up by the positive pressure air AR, passes upward through the cover tape pull-out opening 46H, and moves to the upper surface side of the tape cover 46 (Fig. 7). Fig. 7 is a cross-sectional view of a portion of a tape feeder provided in a component mounting system according to an embodiment of the present disclosure.
[0037] Once the extension portion ES of the cover tape TT has moved above the tape cover 46, the cover tape retraction portion 48 pulls the extension portion ES of the cover tape TT upward while sandwiching it between the drive roller 48a and two driven rollers 48b, moving the extension portion ES upstream along a path that follows the outer periphery of the drive roller 48a (FIG. 6(b)). This pull-up operation of the cover tape TT is performed in synchronization with the transport operation of the component supply tape BT. In other words, the cover tape TT is peeled off in parallel with the transport of the component supply tape BT.
[0038] In this way, the position where the cover tape TT is peeled off from the carrier tape CT is located upstream of the component removal opening 46K, so the pocket PK is uncovered by the tape cover 46 before it reaches the component removal position 21T. Therefore, the component BH in the pocket PK that has reached the component removal opening 46K is exposed upward through the component removal opening 46K. Therefore, the mounting head 13 can suck and remove (pick up) the component BH located at the component removal position 21T by inserting the nozzle 13N through the component removal opening 46K.
[0039] As the tape feeder 21 transports the current tape BT1, when the end of the current tape BT1 separates from the reel RL, the tape feeder 21 transports the current tape BT1 that has separated from the reel RL to the end and discharges it from the tape outlet 42B. If this causes the current tape BT1 to run out of components, the tape feeder 21 moves the next tape BT2 to the transport path 42 and transports it as the new current tape BT1 to continue the component supply operation.
[0040] Once the next tape BT2 has become the current tape BT1 as described above, the operator OP performs the work of replacing the reel RL. In the work of replacing the reel RL, the operator OP first removes the empty reel RL (the reel RL on which the previous current tape BT1 was wound) from the upper reel holder 32, and then moves the lower reel RL that has become the new current tape BT1 to the upper reel holder 32. Then, the operator OP places the new replenishment reel RL in the lower reel holder 32, pulls out the component supply tape BT from that reel RL, and inserts it into the tape inlet 42A of the tape feeder 21 as the new next tape BT2.
[0041] 1 and 2, a vibration applying unit 60 is provided on the feeder cart 22. The vibration applying unit 60 applies vibration to a portion of the component supply tape BT (current tape BT1) being pulled into the tape feeder 21 before it reaches the tape inlet 42A, and includes a pair of rotating member support arms 61, a rotating member 62, and a rotating member drive motor 63. In this embodiment, a vibration control unit 64 that controls the operation of the vibration applying unit 60 is also provided on the feeder cart 22 (FIG. 2).
[0042] The pair of rotating member support arms 61 each extend from the feeder cart 22 toward the front side of the operator OP. The rotating member 62 extends in the X direction (i.e., the direction in which the multiple tape feeders 21 are lined up) and is rotatably supported by the pair of rotating member support arms 61. Therefore, the rotating member 62 is rotatable about an axis 62J (FIG. 1) that is the central axis of the rotating member 62 itself and extends in the X direction (a substantially horizontal axis). The rotating member drive motor 63 functions as a vibration applying actuator, and is controlled by a vibration control unit 64 to drive the rotating member 62 to rotate about the axis 62J.
[0043] 1 and 2, the rotating member 62 is in contact from below with each of the multiple component supply tapes BT (i.e., current tapes BT1) that are pulled out from the upper reels RL and inserted into the tape inlets 42A of the tape feeders 21 located immediately above them. That is, the rotating member 62 is in contact with all of the current tapes BT1 from below (from the carrier tape CT side).
[0044] In this embodiment, the vibration control unit 64 operates the rotating member drive motor 63 in parallel with the transport operation of the component supply tape BT by the tape feeder 21, and applies vibration to the component supply tape BT via the vibration application unit 60. Here, the vibration control unit 64 rotates the rotating member 62 regardless of the operating state of the multiple tape feeders 21 attached to the feeder base 31. As a result, all current tapes BT1 are constantly vibrated by the vibration application unit 60.
[0045] FIG. 8 is a side view of the vicinity of the vibration applying unit included in the component supply system according to the embodiment of the present disclosure.
[0046] In FIG. 8, the rotating member 62 has a plurality of protrusions 71 arranged at intervals along its outer circumferential surface, and these protrusions 71 are adapted to come into contact with the underside of the component supply tape BT (i.e., the carrier tape CT). In this example, the protrusions 71 are formed as protruding portions 72 formed on the outer circumferential surface of the rotating member 62. The protruding portions 72 have two flat portions 72h extending in the X direction and have an overall triangular (triangular prism) shape, but this is merely an example. When driven by the rotating member drive motor 63 controlled by the vibration control unit 64, the rotating member 62 rotates around its axis 62J in a direction in which the upper surface faces from the front side to the rear side of the operator OP (clockwise in FIG. 8; indicated by the arrow R in FIG. 8).
[0047] When the rotating member 62 driven by the rotating member drive motor 63 rotates around the axis 62J, multiple protrusions 71 (protruding portions 72) formed on its outer circumferential surface continuously strike the component supply tape BT from below, causing the component supply tape BT to bounce up in a direction away from the rotating member 62. Meanwhile, the component supply tape BT attempts to return in a direction approaching the rotating member 62 due to its own stiffness and its own weight. As a result, the component supply tape BT repeatedly moves away from and towards the protruding portions 72, i.e., vibrates in an out-of-plane direction (arrow F shown in FIG. 8).
[0048] As a result of the component supply tape BT vibrating in the out-of-plane direction, the components BH in each pocket PK of the component supply tape BT are vibrated within that pocket PK. This corrects any statically charged components BH in each pocket PK that may have been stuck to the cover tape TT (see the component BH marked with the symbol "BHa" in FIG. 8 ). The component BH returns to its normal position (i.e., a position where the component BH is in contact with the bottom of the pocket PK due to its own weight) (see the component BH marked with the symbol "BHb" in FIG. 8 ). Therefore, when the cover tape TT is subsequently peeled off the current tape BT1, the components BH do not pop out of the pocket PK (e.g., pop out of the cover tape pull-out opening 46H of the tape cover 46 toward the top surface of the tape cover 46). This prevents the pocket PK from becoming empty before reaching the component take-out position 21T, allowing the mount head 13 to reliably pick up the components BH at the component take-out position 21T.
[0049] 2, in this embodiment, the vibration control unit 64 is connected to the feeder control unit 45 in terms of signal transmission. Therefore, the vibration control unit 64 can control the rotation of the rotating member 62 based on the transport information of the component supply tape BT detected by the transport detection unit 49 of each tape feeder 21 attached to the feeder base 31 (whether or not each tape feeder 21 is transporting the component supply tape BT).
[0050] In this embodiment, the vibration control unit 64 is configured to operate the rotating member drive motor 63 to rotate the rotating member 62 while it detects that at least one of the plurality of tape feeders 21 is feeding the component supply tape BT, based on the feed information of the component supply tape BT detected by the feed detection unit 49 of each of the plurality of tape feeders 21 attached to the feeder base 31. Thereafter, if it detects that none of the plurality of tape feeders 21 is feeding the component supply tape BT, it stops the rotation of the rotating member 62.
[0051] In the above control, the vibration control unit 64 functions as a determination unit that determines whether a predetermined condition is satisfied, and the vibration application unit 60 applies vibration to the component supply tape BT while the vibration control unit 64 as a determination unit determines that the predetermined condition is satisfied. In this case, the vibration control unit 64 as a determination unit determines that the predetermined condition is satisfied when the conveyance detection unit 49 detects that the tape feeder 21 is conveying the component supply tape BT (here, a state in which at least one of the multiple tape feeders 21 is conveying the component supply tape BT), and applies vibration to the component supply tape BT by the vibration application unit 60 while the tape feeder 21 is conveying the component supply tape BT (at least one of the multiple tape feeders 21 is conveying the component supply tape BT). Then, when the tape feeder 21 is not conveying the component supply tape BT (none of the multiple tape feeders 21 is conveying the component supply tape BT), the vibration application unit 60 stops applying vibration to the component supply tape BT.
[0052] In such a configuration, when none of the multiple tape feeders 21 is transporting the component supply tape BT, the application of vibration to the component supply tape BT (rotation of the rotating member 62) can be stopped, thereby reducing power consumption, which is preferable in terms of operating costs.
[0053] FIG. 9 is a side view of the vicinity of a vibration applying unit showing a first modified example of a component supply system according to an embodiment of the present disclosure.
[0054] 8 has two flat surfaces 72h and an overall triangular (triangular prism) shape, but as shown in Fig. 9 (first modified example), the two flat surfaces 72h in Fig. 8 may be replaced with two curved surfaces 72k. Giving the protrusion 72 a shape with such curved surfaces 72k is preferable because it can reduce damage to the component supply tape BT when the component supply tape BT is flipped up, and also reduce damage to the protrusion 72 from the component supply tape BT.
[0055] FIG. 10 is a side view of the vicinity of the vibration applying unit showing a second modified example of the component supply system according to the embodiment of the present disclosure.
[0056] Alternatively, the protrusion 71 may be a protruding member 73 provided (attached) on the outer circumferential surface of the rotating member 62. For example, as shown in FIG. 10 (second modified example), the protruding member 73 may be configured to include a support member 73s whose base end is attached to the outer circumferential surface of the rotating member 62 and a tapping member 73k supported at the tip of the support member 73s. Here, the tapping member 73k is formed of a sphere or a cylinder extending in the X direction, and is supported on the surface of the rotating member 62 by the elastic support member 73s. The shape of the tapping member 73k is not particularly limited. In this second modified example, the elastic force of the support member 73s causes the tapping member 73k to whip (knock up) the component supply tape BT from below. This effectively shakes the components BH in the pocket PK, thereby more reliably separating the components BH from the cover tape TT.
[0057] As described above, the component mounting system 1 in this embodiment includes a component mounting unit 2 that picks up components BH using a mounting head 13 and mounts them on a board KB, and a component supply unit 3 that supplies components BH to the component mounting unit 2. The component supply unit 3 is configured to include a tape feeder 21 that supplies components BH to a component removal position 21T by drawing in and transporting a component supply tape BT, which is composed of a carrier tape CT that stores components BH in a pocket PK and has a cover tape TT attached thereto, from a tape inlet 42A, and a vibration application unit 60 that applies vibration to the portion of the component supply tape BT that is drawn into the tape feeder 21 before it reaches the tape inlet 42A.
[0058] The component mounting system 1 configured as described above can employ a component supply method in which components BH stuck to the cover tape TT in the pocket PK are separated from the cover tape TT by applying vibration to a portion of the component supply tape BT before it reaches the tape inlet 42A as it is drawn into the tape feeder 21. With this component supply method, even if components BH in the pocket PK are charged with static electricity or the like and stuck to the cover tape TT, this can be corrected and the components BH can be returned to their normal position (a position in which they contact the bottom surface of the pocket PK under their own weight).
[0059] Therefore, according to the component mounting system 1 (feeder cart 22, component supply method) of this embodiment, the component BH does not fly out of the pocket PK when the cover tape TT is peeled off from the current tape BT1, and the pocket PK does not become empty before it reaches the component take-out position 21T. Therefore, the mounting head 13 can reliably pick up the component BH by suction at the component take-out position 21T.
[0060] FIG. 11 is a side view illustrating a third modified example of the component supply system according to the embodiment of the present disclosure.
[0061] In the above-described embodiment, the tape feeder 21 is configured to spray positive pressure air AR onto the extension portion ES of the cover tape TT of the component supply tape BT, causing it to pass through the cover tape pull-out opening 46H provided in the tape cover 46, and then peeling the extension portion ES from the carrier tape CT by pulling it upward with the cover tape retraction portion 48. However, as shown in FIG. 11 (third variant), the cover tape TT may be folded back toward the front (upstream side) at a position slightly upstream of the component removal position 21T, and then pinched and pulled by a pinch roller 41P provided on the top of the main body 41, thereby peeling the cover tape TT from the carrier tape CT.
[0062] 11, in a reel replacement operation when the component supply tape BT (current tape BT1) is about to run out, first, the end portion of the current tape BT1 is separated from the upper reel RL. Then, the reel RL from which the current tape BT1 has been separated is removed from the upper reel holder 32, and the leading end of the next tape pulled out from the lower replacement reel RL is spliced to the end portion of the current tape BT1, after which the lower reel RL is moved to the upper reel holder 32. For this reason, in this example, the situation in which the next tape is pulled out from the lower reel RL and inserted into the tape inlet 42A of the tape feeder 21, as in the previously described embodiment, does not occur, and therefore the next tape is not installed in front of the current tape BT1.
[0063] 11, the rotating member 62 of the vibration applying unit 60 can be brought into contact with the component supply tape BT from the cover tape TT side. In the example shown in Fig. 11, the rotating member support arm 61 is provided with a tape guide 61G that restricts the movement range of the component supply tape BT so that the component supply tape BT, which is vibrated by the rotation of the rotating member 62, does not move too far away from the rotating member 62.
[0064] 11, the component supply unit 3 is provided with a vibration application unit installation body 80 that is separate from the feeder cart 22, and the vibration application unit 60 is installed on the vibration application unit installation body 80. The vibration application unit installation body 80 is provided with casters 81 on its underside so that it can be moved freely on the floor surface FL, and can be positioned in front of the feeder cart 22 only when necessary. In the example shown in FIG. 11, not only the vibration application unit 60 but also the vibration control unit 64 is installed on the vibration application unit installation body 80, but the vibration control unit 64 may also be installed on the feeder cart 22.
[0065] As described above, according to the component mounting system 1 (feeder cart 22, component supply method) of this embodiment, even if a component BH in a pocket PK becomes charged with static electricity or the like and sticks to the cover tape TT, this can be corrected, and the mounting head 13 can reliably pick up the component BH at the component removal position 21T.
[0066] While the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above and various modifications are possible. For example, in the above-described embodiments, the vibration application unit 60 is installed on the feeder cart 22 or on the vibration application unit installation body 80 that is separate from the feeder cart 22, but it may be attached to the tape feeder 21 as an attachment. Furthermore, in the above-described embodiments, the vibration application unit 60 is configured to apply vibration to multiple component supply tapes BT taken in by multiple tape feeders 21 using a single rotating member 62, but it may also be configured to include multiple vibration application units 60, and to apply vibration individually to each component supply tape BT using these multiple vibration application units 60.
[0067] Although various embodiments have been described above with reference to the accompanying drawings, the present disclosure is not limited to such examples. It is clear that those skilled in the art can conceive of various modifications, alterations, substitutions, additions, deletions, and equivalents within the scope of the claims, and it is understood that these also fall within the technical scope of the present disclosure. Furthermore, the components of the various embodiments described above may be combined in any manner without departing from the spirit of the invention. [Industrial Applicability]
