Description

[Technical Field]

[0001] The present invention relates to a component supplying device that transports a carrier tape in which components stored in pockets are covered with a cover tape and supplies the components to a component removal position. [Background technology]

[0002] Conventionally, tape feeders have been known as one type of component supply device used in component mounting devices. Tape feeders supply components stored in pockets to a component removal position by conveying a carrier tape configured such that components are covered with a cover tape. Tape feeders include a main body having a carrier tape conveyance path, and a tape cover provided on the main body to cover a portion of the conveyance path from above. The tape cover has a pull-out opening for pulling out the cover tape peeled off from the carrier tape (see, for example, Patent Document 1 listed below). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-74031 Summary of the Invention [Problem to be solved by the invention]

[0004] Components in the pockets of the carrier tape are usually in contact with the bottom of the pocket due to their own weight, but if the components become charged due to static electricity or the like, they may stick to the cover tape from the inside of the pocket. If the carrier tape is transported on the transport path with components stuck to the cover tape in this state, when the cover tape is peeled off from the carrier tape, the components stuck to the cover tape may collide with the edge on the downstream side of the withdrawal opening and be damaged, or they may pass through the withdrawal opening while still stuck to the cover tape and fall out of the pocket.

[0005] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a component supplying device that can prevent problems that occur when the carrier tape is transported with components in the pockets still attached to the cover tape. [Means for solving the problem]

[0006] The component supply device of the present invention is a component supply device that transports a carrier tape in which components stored in a pocket are covered with cover tape and supplies the components to a component removal position, and comprises: a main body having a transport path for the carrier tape; and a tape cover that is provided on the main body and covers part of the transport path from above, and has a pull-out opening for pulling out the cover tape peeled off from the carrier tape upward, the pull-out opening being formed between an upstream portion that holds the carrier tape before the cover tape is peeled off and a downstream portion that holds the carrier tape after the cover tape has been peeled off, the upstream portion having a protruding piece that protrudes toward the downstream portion, and when the cover tape is peeled off from the carrier tape, the components in the pocket are pressed downward by the tip edge of the protruding piece. [Effects of the Invention]

[0007] According to the present invention, it is possible to prevent problems that occur when the carrier tape is transported with components in the pockets still attached to the cover tape. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a component mounting device equipped with a tape feeder in one embodiment of the present invention. FIG. 1 shows a component mounting device 1 equipped with a tape feeder, which is one embodiment of the component supply device of the present invention. The component mounting device 1 is a device that mounts components BH on a board KB, and is equipped with a board transport unit 12 on a base 11. A mounting head 13 is provided above the base 11. The mounting head 13 is moved horizontally by a head movement mechanism (not shown). The mounting head 13 is equipped with a plurality of nozzles 14 extending downward.

[0010] The substrate transport unit 12 transports the substrate KB horizontally and positions it at a predetermined working position. Hereinafter, the transport direction of the substrate KB by the substrate transport unit 12 is referred to as the X direction, and the horizontal direction perpendicular to the X direction is referred to as the Y direction. The up-down direction is referred to as the Z direction. Furthermore, within the Y direction, the direction toward the center of the base 11 is referred to as the "front," and the direction facing the opposite direction is referred to as the "rear."

[0011] In Figure 1, a carriage 15 is connected to the rear end of base 11. Carriage 15 has a feeder base 15a and a reel holder 15b. A plurality of tape feeders 16 are attached to feeder base 15a and aligned in the X direction. Each tape feeder 16 is detachably attached to feeder base 15a.

[0012] 1, reel holder 15b holds a plurality of reels RL aligned in the X direction, each corresponding to a respective one of a plurality of tape feeders 16 attached to feeder base 15a. Carrier tape CT is wound around each reel RL.

[0013] 2(a) and 2(b) are perspective views of the leading end of a carrier tape fed by a tape feeder according to an embodiment of the present invention. In FIGS. 2(a) and 2(b), a number of pockets PK for storing components are arranged in a row on the carrier tape CT. A number of feed holes KH are arranged in a row on the carrier tape CT parallel to the row of pockets PK. Each pocket PK stores one component BH, and the component BH in the pocket PK is covered with a cover tape TT attached to the top surface of the carrier tape CT and sealed within the pocket PK. In other words, the carrier tape CT is configured such that the components BH stored in the pocket PK are covered with the cover tape TT.

[0014] 2(a), the tip of the cover tape TT is processed so as to extend a certain length beyond the tip of the carrier tape CT. Hereinafter, the part 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.

[0015] 3, tape feeder 16 is configured with a main body 21 as a base, which is detachably attached to feeder base 15a. A transport path 22, which is a passage for transporting carrier tape CT, is formed inside main body 21. The upper surface of transport path 22 is a transport surface 22M of carrier tape CT.

[0016] Figure 3 is a side view of a tape feeder according to an embodiment of the present invention. In Figure 3, a tape insertion opening 23 is formed at the rear end of main body 21, through which carrier tape CT pulled out from reel RL is inserted from its leading end. A tape ejection opening 24 is formed at the front end of main body 21, through which carrier tape CT is ejected after traveling through transport path 22. A component removal position 16T, from which mounting head 13 removes components BH, is set between positioning sprocket 32 and ejection sprocket 33 on the top surface of main body 21.

[0017] 3, a transport mechanism 30 is provided within the main body 21 to transport the carrier tape CT inserted through the tape insertion port 23 along the transport path 22. As shown in Fig. 3, the transport mechanism 30 includes three sprockets (an introduction sprocket 31, a positioning sprocket 32, and a discharge sprocket 33) aligned from rear to front, and a sprocket drive motor 34. The sprocket drive motor 34 is operated under the control of a feeder control unit 35 (Fig. 3) provided within the main body 21, and rotates the three sprockets synchronously in the same direction (clockwise in Fig. 3) via a gear mechanism (not shown).

[0018] Figure 4 is a side view of a portion of a tape feeder according to one embodiment of the present invention. In Figure 4, a plurality of feed pins PN are provided on the outer periphery of each of three sprockets (introduction sprocket 31, positioning sprocket 32, and discharge sprocket 33). When these three sprockets are driven to rotate by sprocket drive motor 34, the feed pins PN of each sprocket engage with feed holes KH provided in the carrier tape CT from below, advancing the carrier tape CT forward (downstream) on the conveying path 22. At this time, the carrier tape CT is delivered in the order of introduction sprocket 31, positioning sprocket 32, and discharge sprocket 33.

[0019] 3 and 4, a tape cover 40 is provided on the upper part of the main body 21. The tape cover 40 covers from above a part of the region between the entrance sprocket 31 and the discharge sprocket 33 of the carrier tape CT transported along the transport path 22. In this manner, in the present embodiment, the tape cover 40 is provided on the main body 21 and covers a part of the transport path 22 from above.

[0020] Fig. 5 is a perspective view of a tape cover provided in a tape feeder according to an embodiment of the present invention. In Fig. 5, tape cover 40 is made up of a single plate-like member, and its lower surface is shaped to generally conform to the upper surface of conveying path 22. The rear portion of tape cover 40 (the portion where carrier tape CT on conveying path 22 enters) forms an inclined portion 41 that is inclined relative to conveying path 22 so that the height from conveying path 22 (conveying surface 22M) increases toward the rear (upstream side) (see also Fig. 6, which is an enlarged view of area AR1 in Fig. 5).

[0021] Fig. 6 is an enlarged perspective view of a portion of a tape cover provided in a tape feeder according to an embodiment of the present invention. In Figs. 5 and 6, a pull-out opening 42 for pulling upward the cover tape TT peeled off from the carrier tape CT is provided in a portion slightly downstream of the base of the inclined portion 41 of the tape cover 40 (i.e., upstream of the component removal position 16T). The pull-out opening 42 is formed between an upstream portion 43 that holds the carrier tape CT before the cover tape TT is peeled off, and a downstream portion 44 that holds the carrier tape CT after the cover tape TT has been peeled off (see also Fig. 7).

[0022] Fig. 7 is a plan view showing a portion of a tape cover provided in a tape feeder according to an embodiment of the present invention, together with a carrier tape. In Figs. 6 and 7, an upstream portion 43 of tape cover 40 is formed with a protruding piece 45 that protrudes toward downstream portion 44. Protruding piece 45 has a shape (in this embodiment, an overall triangular shape) whose width dimension (X-direction dimension) gradually decreases toward the downstream side.

[0023] Fig. 8 is a plan view of a portion of a tape feeder according to an embodiment of the present invention. As shown in Figs. 7 and 8, at least a portion of leading edge 45E of protruding piece 45 is positioned so as to face up and down the upper surface of a part BH that passes below leading edge 45E. In this embodiment, both ends 45P of leading edge 45E of protruding piece 45 are positioned so as to face up and down the upper surface of a part BH that passes below leading edge 45E.

[0024] 6, 7, and 8, in this embodiment, the edge (downstream edge 44E) of the downstream portion 44 extends straight along the width direction (X direction). The downstream edge 44E has the function of guiding the extension portion ES of the cover tape TT extending from the leading end of the carrier tape CT upward (i.e., in a direction away from the conveying path 22).

[0025] 7, i.e., the minimum distance in the transport direction (Y direction) of the carrier tape CT between the downstream edge 44E of the downstream portion 44 and the leading edge 45E of the protruding piece 45, is set to a dimension smaller than the thickness of the carrier tape CT and larger than the thickness of the cover tape TT. Also, the width direction dimension L2 of the pull-out opening 42 shown in FIG. 7 is set to a dimension larger than the width dimension U1 of the cover tape TT and smaller than the width dimension U2 of the carrier tape CT.

[0026] 6 and 7, an air escape section 46 is provided at each of both widthwise ends of the draw-out opening 42. These two air escape sections 46 are connected to both widthwise (X-direction) ends of the draw-out opening 42. In the present embodiment, one of the two air escape sections 46 (the left side in FIG. 7) is provided inside the tape cover 40, and the other (the right side in FIG. 7) is provided facing the side edge of the tape cover 40.

[0027] 5, a component removal opening 40K is provided near the downstream end of tape cover 40. Component removal opening 40K is an opening for removing components BH by nozzle 14 from carrier tape CT transported on transport path 22 by transport mechanism 30, and is located above component removal position 16T described above.

[0028] 5, a sprocket avoidance hole 47 is provided slightly upstream of the component removal opening 40K. The sprocket avoidance hole 47 is an elongated hole extending in the longitudinal direction (Y direction) of the tape cover 40. The sprocket avoidance hole 47 has the function of preventing interference between the feed pin PN of the positioning sprocket 32 and the tape cover 40.

[0029] 3 and 4, an air ejection part 61 that ejects air upward is provided inside the main body part 21. The air ejection part 61 is located below the outlet .

[0030] FIG. 9 is a perspective view showing an air ejection unit provided in a tape feeder according to an embodiment of the present invention, together with a portion of the tape cover. FIG. 10(a) is a side cross-sectional view of a portion of the tape feeder according to an embodiment of the present invention. FIG. 10(b) is a plan view of a portion of the tape feeder according to an embodiment of the present invention. In FIGS. 9 and 10(a), air ejection unit 61 is attached to a main body side base 62 that is a part of the frame that constitutes main body 21. Air ejection unit 61 has two ejection ports 61H that are arranged side by side in the width direction (i.e., X direction) of tape cover 40 (FIGS. 9 and 10(b)). These two ejection ports 61H extend through block-shaped air ejection unit 61 in the thickness direction (Z direction).

[0031] 10(a), a communication space 63 is formed in the main body base 62, opening to the upper surface, and an air pipe 64 is connected to the communication space 63. The communication space 63 is connected to both of the two air outlets 61H. Therefore, when positive pressure is supplied to the air pipe 64, air (positive pressure air) is ejected from each of the two air outlets 61H of the air ejection part 61 through the communication space 63.

[0032] 3, an air plug 66 is provided in the lower rear portion 21K of the main body 21, protruding forward (to the right side of the paper in FIG. 3). An air pipe 64 extends inside the main body 21 and is connected to the air plug 66 via an air ejection control valve 65 provided inside the main body 21.

[0033] When the tape feeder 16 is attached to the feeder base 15a, the air plug 66 fits into an air socket (not shown) provided on the feeder base 15a. The air socket is connected to a positive pressure source (not shown). Therefore, with the tape feeder 16 attached to the feeder base 15a, positive pressure can be supplied to the air pipe 64 via the air socket and air plug, and air can be ejected from each of the two ejection ports 61H by controlling the air ejection control valve 65 from the feeder control unit 35.

[0034] 9, the two outlets 61H of the air ejection unit 61 are positioned opposite the two air escape sections 46 formed in the tape cover 40 in the direction along the flow of the air 67 (substantially the vertical direction). Therefore, the air 67 ejected from each of the two outlets 61H flows above the tape cover 40 through each of the two air escape sections 46, as shown in FIG.

[0035] When the air 67 is blown up, the extension portion ES, which is approaching the pull-out opening 42, is blown up by the air 67 and passes through the pull-out opening 42 and enters above the tape cover 40. As described above, the minimum distance L1 of the pull-out opening 42 shown in FIG. 7 is set to a dimension that is smaller than the thickness of the carrier tape CT and larger than the thickness of the cover tape TT. Therefore, the carrier tape CT transported along the transport path 22 cannot pass through the pull-out opening 42, but the cover tape TT peeled off from the carrier tape CT can pass through the pull-out opening 42.

[0036] In this embodiment, the air ejection section 61 ejects air 67 from below the tape cover 40, blowing up the extension section ES of the carrier tape CT being transported along the transport path 22 and moving it above the tape cover 40 from the withdrawal opening 42 between the downstream edge 44E and the tip edge 45E of the protruding piece 45.

[0037] Figures 11(a) and 11(b) are side views of a portion of a tape feeder according to one embodiment of the present invention. In Figures 3, 4, and 11(a) (Figure 11(a) is an enlarged view of area AR2 in Figure 4), a tape retraction section 74 consisting of three rollers (a first roller 71, a second roller 72, and a third roller 73) is provided within main body 21. These three rollers are located above tape outlet 42 provided in tape cover 40.

[0038] All three rollers are made of gears. The second roller 72 and the third roller 73 each have a smaller diameter than the first roller 71 and are in mesh with the first roller 71. The second roller 72 is located downstream of the first roller 71, and the third roller 73 is located above the first roller 71 (upstream of the second roller 72).

[0039] The driving force of the sprocket drive motor 34 is transmitted to the first roller 71 via a power transmission mechanism (not shown). When the first roller 71 is driven by the sprocket drive motor 34 and rotates, the second roller 72 and the third roller 73 that mesh with the first roller 71 also rotate. At this time, the second roller 72 and the third roller 73 rotate in the opposite direction to the first roller 71. Specifically, the first roller 71 rotates counterclockwise in FIG. 11(a) (indicated by arrow R1 in the figure), and the second rollers 72 and 73 each rotate clockwise in FIG. 11(a) (indicated by arrow R2 in the figure). These three rollers operate at a timing that is linked to the operation of the three sprockets (inlet sprocket 31, positioning sprocket 32, and discharge sprocket 33).

[0040] 11(a), a guide portion 81 is provided on the downstream side of the first roller 71. A guide surface 81M, which is the upstream surface of the guide portion 81 (the surface on the first roller 71 side), is formed in an arc shape along the outer circumferential surface of the first roller 71.

[0041] 4 and 11(a), a partitioning member 82 is provided above the transport path 22. The partitioning member 82 extends in the Y direction within the main body 21, and divides the space above the transport path 22 in the main body 21 into upper and lower sections. The upper region partitioned by the partitioning member 82 serves as a cover tape discharge space 83 into which the cover tape TT is fed after being peeled off from the carrier tape CT.

[0042] When the tape feeder 16 having the above configuration is to supply components BH, the operator first inserts the leading end of the carrier tape CT, on which the extension portion ES of the cover tape TT has been formed, into the tape insertion opening 23. Then, the carrier tape CT is pushed downstream until the leading end of the carrier tape CT abuts against the feed pin PN of the lead-in sprocket 31.

[0043] The operator pushes the carrier tape CT in until the leading end of the carrier tape CT abuts the feed pin PN of the introduction sprocket 31, and then operates an operation start switch (not shown). When the feeder control unit 35 detects that the operation start switch has been operated, it activates the sprocket drive motor 34, causing three sprockets (the introduction sprocket 31, the positioning sprocket 32, and the discharge sprocket 33) to rotate. As a result, the carrier tape CT in the conveying path 22 is conveyed downstream by the three sprockets.

[0044] FIG. 12(a) is a side view of a portion of a tape feeder according to an embodiment of the present invention. FIG. 12(b) is a side view of a portion of a tape feeder according to an embodiment of the present invention. As the carrier tape CT is transported downstream, when the extension portion ES of the cover tape TT enters the area below the inclined portion 41 of the tape cover 40, the feeder control unit 35 activates the air ejection control valve 65 to eject air 67 from the air ejection unit 61 (specifically, two ejection ports 61H) ( FIG. 11(b) ). As a result, the extension portion ES of the cover tape TT approaching the pull-out opening 42 is blown upward by the air 67 ejected from the ejection ports 61H, passes through the pull-out opening 42, and moves toward the upper surface of the tape cover 40 ( FIG. 12(a) ). When the extension portion ES of the cover tape TT passes above the pull-out opening 42, the feeder control unit 35 stops the ejection of air 67 from the air ejection unit 61.

[0045] As the carrier tape CT is further transported after the extension portion ES passes above the tape cover 40 through the pull-out opening 42, the leading end of the carrier tape CT abuts against the underside of the inclined portion 41 of the tape cover 40 (FIG. 12(a)), and advances between the underside of the tape cover 40 and the transport path 22 (transport surface 22M) while pushing up the entire tape cover 40. As a result, the leading end of the extension portion ES of the cover tape TT that has moved above the tape cover 40 through the pull-out opening 42 is sandwiched (caught) by the first roller 71 and second roller 72, which rotate in opposite directions, and is pulled up.

[0046] As described above, the first roller 71 and the second roller 72 operate in a timing that is synchronized with the three sprockets (the lead-in sprocket 31, the positioning sprocket 32, and the discharge sprocket 33). Therefore, the lifting of the cover tape TT by the first roller 71 and the second roller 72 is synchronized with the advancement of the carrier tape CT.

[0047] When the carrier tape CT advances along the transport path 22 with the extension portion ES of the cover tape TT passing upward through the pull-out opening 42, the downstream edge 44E constituting the pull-out opening 42 enters between the carrier tape CT and the cover tape TT. Therefore, as the carrier tape CT advances further, the cover tape TT is peeled off from the carrier tape CT almost in synchronization with the advancement of the carrier tape CT (FIG. 12(b)). In this way, the cover tape TT is peeled off from the carrier tape CT with the pull-out opening 42 (more specifically, the downstream edge 44E) of the tape cover 40 serving as the peeling position.

[0048] When the cover tape TT is pulled upward by the tape retraction portion 74, the pulling force is concentrated on the leading edge 45E of the protruding piece 45. As a result, the cover tape TT is peeled off from the carrier tape CT starting from the leading edge 45E of the protruding piece 45 (arrow H shown in FIG. 8).

[0049] 13 is a side view of a portion of a tape feeder according to an embodiment of the present invention. As described above, at least a portion of the leading edge 45E of the protruding piece 45 is positioned so as to face the top surface of the component BH in the vertical direction. Therefore, at least a portion of the cover tape TT is peeled off from the carrier tape CT starting from directly above the component BH (FIG. 8). Even if the component BH is attached to the cover tape TT, the component BH is forcibly separated from the cover tape TT (FIG. 13). This prevents problems caused by the component BH in the pocket PK of the carrier tape CT attaching to the cover tape TT.

[0050] Furthermore, if the minimum spacing L1 of the withdrawal opening 42 shown in Figure 7 is set to be smaller than the minimum dimension of the component BH, the component BH attached to the cover tape TT will not slip out of the withdrawal opening 42 above the tape cover 40, and the component BH can be prevented from passing through the withdrawal opening 42 and moving above the tape cover 40.

[0051] The cover tape TT, which has been peeled off from the carrier tape CT and passed through the pull-out opening 42 onto the upper surface side of the tape cover 40 as described above, is caught and pulled up by the first roller 71 and the second roller 72, and then guided by the guide surface 81M of the guide portion 81 to move rearward (upstream) along an arc-shaped trajectory that follows the outer peripheral surface of the first roller 71 (FIG. 12(b)). Thereafter, the cover tape TT is sandwiched between the first roller 71 and the third roller 73, which rotate in opposite directions, and transported rearward (upstream), and is sent out into the cover tape discharge space 83 described above.

[0052] As described above, when the cover tape TT is peeled off from the carrier tape CT with the pull-out opening 42 serving as the peeling position, the components BH in the pocket PK are no longer covered by the cover tape TT downstream of the peeling position, but are instead covered from above by the tape cover 40. Therefore, even after passing the peeling position, the components BH in the pocket PK remain stored in the pocket PK until they reach the component removal position 16T (component removal opening 40K).

[0053] When the component BH stored in the carrier tape CT reaches the component removal position 16T, it is exposed upward through the component removal opening 40K of the tape cover 40. Therefore, the mounting head 13 can insert the nozzle 14 through the component removal opening 40K to suck and remove the component BH located at the component removal position 16T (pick up the component BH from inside the pocket PK).

[0054] When component mounting device 1 having tape feeders 16 of this configuration as a component supply device performs a component mounting operation of mounting components BH onto board KB, first, board KB supplied from outside component mounting device 1 is carried in by board transport unit 12 and positioned at a predetermined work position. Once board KB is positioned at the work position, each tape feeder 16 operates to supply component BH to component removal position 16T, and mounting head 13 picks up and removes component BH from tape feeder 16 using nozzle 14. Mounting head 13 then moves the picked-up component BH above board KB and mounts it at a predetermined target component mounting position on board KB.

[0055] Once the mounting head 13 has mounted all of the components BH to be mounted on the board KB in the manner described above, the board transport unit 12 carries the board KB out of the component mounting device 1. This completes the component mounting operation for one board KB.

[0056] As described above, the tape feeder 16 serving as a component supply device in this embodiment has a protruding piece 45 that protrudes from an upstream portion 43 located upstream of the cover tape TT pull-out opening 42 and that presses the carrier tape CT before the cover tape TT is peeled off, toward a downstream portion 44 that presses the carrier tape CT after the cover tape TT is peeled off. When the cover tape TT is peeled off from the carrier tape CT, the protruding piece 45 presses the cover tape TT downward by a leading edge 45E of the protruding piece 45. Because the cover tape TT is peeled off from the carrier tape CT starting from the leading edge 45E of the protruding piece 45, at least a portion of the cover tape TT peels off from the carrier tape CT starting from directly above a component BH. Even if a component BH is attached to the cover tape TT, the component BH is forcibly separated from the cover tape TT. Therefore, the tape feeder 16 in this embodiment can prevent problems caused by a component BH in a pocket PK of the carrier tape CT sticking to the cover tape TT.

[0057] Although the present invention has been described above in terms of an embodiment, the present invention is not limited to the above and various modifications are possible. For example, in the above embodiment, the protruding piece 45 formed on the upstream portion 43 of the tape cover 40 has a shape in which the width dimension gradually decreases toward the downstream side, but the shape does not necessarily have to be such that the width dimension gradually decreases toward the downstream side. Furthermore, when the shape gradually decreases in width toward the downstream side, it is not limited to the triangular shape shown in the above embodiment, and may be a semicircular shape, a semi-elliptical shape, or the like.
