Description

The present invention relates to a tape feeder that conveys a carrier tape containing parts and supplies the parts to a parts supply position, and a component mounting device that mounts the parts supplied by the tape feeder on a substrate.

Conventionally, a component mounting device is known as a device that picks up parts supplied by a parts feeder by a mounting head and mounts them on a positioned board. The tape feeder, which is often used as a parts feeder for component mounting devices, transports carrier tape containing parts in each of a plurality of pockets arranged side by side in a transport path formed in a frame to supply parts. It is configured to supply parts to.

In order to ensure that the mounting head can take out the parts supplied by the tape feeder with such a configuration to the parts supply position by the nozzle, the parts in the carrier tape are regular when they reach the parts supply position. It must be in a posture (horizontal posture). However, if the parts run wild in the pocket while the carrier tape is being conveyed, the parts are not in the proper posture when the parts supply position is reached, and a pickup error due to the mounting head may occur. Especially in the embossed type carrier tape, pick-up mistakes due to such rampage of parts tend to occur particularly easily. For this reason, conventionally, a suction block made of a hollow block-shaped member having a suction port on the upper surface is installed on the frame, and a vacuum pressure is supplied to the internal space of the suction block to generate a suction force in the suction port. It is known that the parts in the carrier tape approaching the parts supply position by the carrier tape are pulled downward to suppress the runaway of the parts (see, for example, Patent Document 1 below).

Japanese Unexamined Patent Publication No. 2005-35637

However, in order for the suction block to suck the parts, a pipeline (vacuum tube) for supplying vacuum pressure to the suction block is required, and this vacuum tube is arranged along the side surface of the frame. I had no choice but to do it. For this reason, there is a problem that the size of the tape feeder as a whole becomes large, and when the tape feeders are mounted side by side, the number of tape feeders that can be equipped is reduced, and the productivity may be reduced accordingly.

Therefore, an object of the present invention is to provide a tape feeder having a suction block but a compact size, and a component mounting device provided with the tape feeder.

The tape feeder of the present invention is a tape feeder that transports a carrier tape containing a component and supplies the component to a component supply position, and is provided on the frame in which the carrier tape transport path is formed and the frame. A suction force is generated in the tape transport portion that transports the carrier tape in the transport path so as to pass through the component supply position and the suction port provided on the upper surface by supplying vacuum pressure, and the tape transport is performed. A suction block that sucks the parts in the carrier tape that reach the component supply position by the transport of the carrier tape by the unit, a vacuum tube that supplies vacuum pressure to the suction block, and the transport path in the frame. A vacuum tube installation passage extending along the transport path is provided below the vacuum tube, and the vacuum tube is installed in the vacuum tube installation passage.

The component mounting device of the present invention includes the tape feeder of the present invention and a mounting head that picks up the components supplied by the tape feeder to the component supply position by a nozzle and mounts the components on the substrate.

According to the present invention, it is possible to provide a tape feeder having a suction block but having a compact overall size, and a component mounting device including the tape feeder.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a component mounting device 1 according to the first embodiment of the present invention. The component mounting device 1 is a device that executes component mounting work for mounting the component BH on the board KB, and includes a base 11, a board transport unit 12, a carriage 13, a tape feeder 14, a mounting head 15, a head moving mechanism 16, and a component. It includes a recognition camera 17 and a control device 18.

In FIG. 1, the substrate transport portion 12 is provided on the base 11, and the substrate KB is supported and transported from below by a pair of horizontally extending conveyors 12a. In the present embodiment, for convenience of explanation, the transport direction of the substrate KB by the substrate transport unit 12 is the X direction (horizontal direction), and the vertical direction is the Z direction. Further, the direction orthogonal to both the X direction and the Z direction is defined as the Y direction (front-back direction).

In FIG. 1, the bogie 13 is connected to the end of the base 11 in the Y direction. A feeder base 13F is provided on the upper part of the carriage 13. A plurality of tape feeders 14 are provided side by side in the lateral direction (X direction) of the feeder base 13F. Below the feeder base 13F, a reel RL around which the carrier tape CT containing the component BH is wound is held. Each tape feeder 14 draws the carrier tape CT from the reel RL and conveys the carrier tape CT in the direction (forward) along the Y direction toward the substrate conveying portion 12. As the tape feeder 14 conveys the carrier tape CT forward, the component BH housed in the carrier tape CT is sequentially supplied to the predetermined component supply position 14K (FIGS. 1 and 2 (a)).

In FIG. 1, the mounting head 15 includes a plurality of nozzles 15N extending downward. The mounting head 15 raises and lowers each nozzle 15N individually and rotates it around the Z axis. The mounting head 15 can generate an attractive force at the lower end of the nozzle 15N by supplying a vacuum pressure into the nozzle 15N. The head moving mechanism 16 is composed of, for example, an XY table mechanism, and moves the mounting head 15 in a horizontal plane (in the XY plane). As a result, the mounting head 15 picks up the component BH supplied by the tape feeder 14 to the component supply position 14K above the tape feeder 14 by the nozzle 15N, and then passes above the component recognition camera 17 and moves above the substrate KB. Then, the picked up component BH is mounted on the board KB.

In FIG. 1, the component recognition camera 17 is attached to the base 11 in a posture in which the image pickup optical axis is directed upward. When the mounting head 15 that picks up the component BH passes above the component recognition camera 17, the component BH is imaged from below.

The control device 18 (FIG. 1) of the component mounting device 1 controls the operation of each part of the component mounting device 1 based on the component mounting program stored in advance, and causes the board KB to execute the component mounting operation of mounting the component BH. In the component mounting work, first, the board transport unit 12 receives and transports the board KB sent from the upstream of the component mounting device 1, and positions the board KB at the work position. When the board transfer unit 12 positions the board KB at the working position, the head moving mechanism 16 reciprocates between the tape feeder 14 and the board KB on the mounting head 15, and the component BH supplied by the tape feeder 14 is moved on the board KB. The mounting turn to be mounted on the vehicle is repeatedly executed.

One mounting turn by the mounting head 15 is performed by the operation of picking up the component BH supplied by the tape feeder 14 to the component supply position 14K by the nozzle 15N and passing above the component recognition camera 17 while holding the picked up component BH. It comprises an operation of causing the component recognition camera 17 to image the component BH and an operation of mounting the component BH imaged by the component recognition camera 17 on the target mounting coordinates on the substrate KB. When the component BH is mounted at the target mounting coordinates, the position of the mounting head 15 (nozzle 15N) is corrected based on the recognition information of the component BH obtained by imaging the component BH by the component recognition camera 17.

When all the component BHs to be mounted on the board KB are mounted by repeatedly executing the mounting turn by the mounting head 15, the board transport unit 12 operates to carry out the board KB from the component mounting device 1. This completes the component mounting work per board KB.

In the component mounting device 1 having such a configuration, the tape feeder 14 is characterized in the present embodiment, and the tape feeder 14 will be described below. First, the configuration of the carrier tape CT will be described.

In FIGS. 3 and 4 (FIG. 4 is a cross-sectional view taken along the line V1-V1 in FIG. 3), the carrier tape CT has a configuration in which the top tape TT is attached to the upper surface of the base tape BT. The base tape BT is provided with a plurality of pockets (embossed portions EB) recessed downward in a row in the longitudinal direction, and a plurality of feed holes SH are arranged in a row in parallel with the row of the embossed portions EB. It is provided in.

As shown in FIG. 4, the component BH is housed in each embossed portion EB. The component BH in each embossed portion EB is in a state of being enclosed in the embossed portion EB by attaching the top tape TT to the base tape BT. At the bottom of each embossed portion EB, an air hole EH having an inner diameter of a minute dimension is provided (see also FIG. 3).

In FIG. 2A, the tape feeder 14 includes a frame 21, a cover member 22, a tape transport section 23, and a top tape recovery section 24. The frame 21 has a thin box shape that extends in the YZ plane as a whole. A slider 21T projecting downward is formed on the lower surface of the frame 21, and the slider 21T is slid into a slot (not shown) provided on the upper surface of the feeder base 13F to cause the tape feeder 14 to move to the feeder base 13F. Attached to.

In FIGS. 2 (a) and 2 (b) (FIG. 2 (b) is an enlarged cross-sectional view of the region R1 in FIG. 2 (a)), the frame 21 has a transport path 21L for guiding the transport of the carrier tape CT. It is formed. The transport path 21L extends from the rear end portion to the front end portion of the frame 21, and is open to each of the lower rear end portion and the upper front end portion of the frame 21. The lower rear opening of the transport path 21L is the inlet opening 21A into which the carrier tape CT is inserted, and the upper opening on the front side of the transport path 21L is the outlet opening 21B into which the carrier tape CT is discharged.

In FIG. 2A, the transport path 21L extends substantially horizontally from the entrance opening 21A at the rear end of the frame 21 toward the downstream, and then becomes an uphill in the middle portion of the frame 21, and from the end of this uphill. It has a shape that extends almost horizontally to reach the outlet opening 21B. A certain area of the transport path 21L immediately before the outlet opening 21B of the frame 21 is in a state of being opened above the frame 21.

In FIG. 2A, the cover member 22 is provided on the upper part of the front end of the frame 21 and covers at least a part of the transport path 21L opened upward from above. As shown in FIGS. 5 and 6 (V2-V2 cross-sectional view in FIG. 5), the cover member 22 has a horizontal upper wall portion 22a and left and right side wall portions 22b extending downward from both left and right ends of the upper wall portion 22a. It has a channel-shaped shape that extends in the front-rear direction (Y direction) of the frame 21 and opens downward.

In FIGS. 5 and 6, when the cover member 22 covers a part of the upper part of the frame 21, the upper wall portion 22a of the cover member 22 is located above the frame 21, and the left and right side wall portions 22b are the frame 21. Located on the outside of the left and right sides of the. The upper wall portion 22a of the cover member 22 is provided with a component outlet 22G penetrating the upper wall portion 22a in the thickness direction (FIGS. 5 and 6). The component outlet 22G is an opening for allowing the mounting head 15 to take out the component BH from the inside of the embossed portion EB of the carrier tape CT located at the component supply position 14K by the nozzle 15N.

In FIG. 2A, the tape transport unit 23 includes a sprocket 31 provided on the frame 21 and a drive motor 32 for rotationally driving the sprocket 31. The sprocket 31 is rotatably provided in the upper region of the front end portion of the frame 21 around an axis parallel to the X direction. The sprocket 31 has engaging pins 31P on its outer peripheral edge at regular intervals (FIG. 3). Among these engagement pins 31P, those located directly above the rotation center of the sprocket 31 (referred to as "top engagement pin 31G") are carrier tape CTs located in the upper region of the sprocket 31 in the transport path 21L. It engages with the feed hole SH from below (FIG. 3).

When the drive motor 32 is operated to rotate the sprocket 31, the uppermost engaging pin 31G of the sprocket 31 moves forward. As a result, the entire carrier tape CT is towed forward and is conveyed forward in the transport path 21L.

In FIGS. 5 and 6, a portion of the cover member 22 located directly above the center of rotation of the sprocket 31 is provided with a relief opening 22M extending in the front-rear direction (Y direction) of the frame 21. Since the uppermost engaging pin 31G of the sprocket 31 moves within the clearance opening 22M, the sprocket 31 can rotate without interfering with the cover member 22.

In FIG. 2A, the top tape collecting portion 24 is provided on the upper side of the intermediate portion in the front-rear direction of the frame 21. The top tape collecting unit 24 includes a pair of feed rollers 24a and a tension applying unit 24b.

As shown in FIGS. 5 and 7 (FIG. 7 is an enlarged cross-sectional view of the region R2 in FIG. 2A), the top tape TT of the carrier tape CT has a frame 21 rather than the component supply position 14K (component outlet 22G). The top tape drawer portion 22T (or the trailing edge of the component outlet 22G) provided at the rear position of the above is set as the peeling position 22H, and the top tape is peeled from the base tape BT and folded back. Then, it is sandwiched between the pair of feed rollers 24a, and an appropriate tension is applied by the tension applying portion 24b.

When the sprocket 31 rotates and the carrier tape CT is conveyed forward, the pair of feed rollers 24a rotate in synchronization with the rotation of the sprocket 31. As a result, the top tape TT is pulled backward by the pair of feed rollers 24a (arrow P shown in FIGS. 2A and 5), and the top tape storage space 21K formed at the rear of the frame 21 (FIG. 2A). )) Will be sent to and collected. The top tape TT housed in the top tape storage space 21K can be taken out of the frame 21 by opening the top tape take-out door 21D (FIG. 2A) provided at the rear end of the frame 21.

As described above, since the top tape TT of the carrier tape CT is peeled off from the base tape BT before reaching the component supply position 14K, each embossed portion EB is opened upward when the component supply position 14K is reached. It will be in a state of being. Therefore, the mounting head 15 can take out (pick up) the component BH located at the component supply position 14K from the component outlet 22G by the nozzle 15N (FIGS. 3 and 7). The carrier tape CT (base tape BT) that has passed through the lower region of the cover member 22 is discharged to the outside of the frame 21 from the outlet opening 21B (FIG. 2A).

As described above, in the tape feeder 14 of the present embodiment, the carrier tape CT is conveyed by the tape conveying unit 23 so that the carrier tape CT in the conveying path 21L passes through the component supply position 14K.

In FIGS. 8 and 9, a bracket 41 extending in the Y-axis direction is provided in the region covered by the cover member 22 of the frame 21. The bracket 41 has a horizontal mounting surface 41H, and a suction block 44 is attached to the mounting surface 41H via a base body 42 and a spacer 43. The base body 42 is attached to the bracket 41 by the screw S1, and the suction block 44 is attached to the base body 42 together with the spacer 43 by the screw S2 (FIG. 9).

In FIG. 9, each of the base bodies 42 has a shape elongated in the Y direction. The base body 42 is a block-shaped member having a flat lower surface and an upper surface, and the upper surface 42a serves as a pedestal for supporting the suction block 44. The spacer 43 is a plate-shaped member having a flat upper surface and a lower surface. The spacer 43 adjusts the vertical position of the upper surface 44a of the suction block 44, and the required number (including 0) according to the thickness of the carrier tape CT (depth of the embossed portion EB) is the base body 42. It is installed in a state of being sandwiched between the suction block 44 and the suction block 44.

As shown in FIGS. 6 and 7, the suction block 44 is made of a hollow block-shaped member extending in the Y direction and having an internal space of 44V. The suction block 44 has a flat upper surface 44a and a flat lower surface 44b. The upper surface 44a and the lower surface 44b are parallel to each other. The upper surface 44a of the suction block 44 is provided with a slit-shaped suction port 44S that opens upward and extends in the Y direction. The slit width HH (FIG. 6), which is the width direction (X direction) of the suction port 44S, has a size slightly larger than the inner diameter of the air hole EH provided at the bottom of the embossed portion EB, and has a size slightly larger than the inner diameter of the air hole EH. It is designed to be located directly below.

A vacuum tube 45 is connected to the suction block 44. The vacuum tube line 45 is made of a tubular member and is connected to the internal space 44V from the side surface of the suction block 44. In this way, by connecting the vacuum tube 45 to the side surface of the suction block 44 instead of the lower surface 44b, the spacer 43 can be sandwiched between the lower surface 44b and the upper surface 42a of the base body 42 without being disturbed by the vacuum tube 45. As shown in FIG. 2A, a vacuum tube line installation passage 51 extending along the transport path 21L is provided below the transport path 21L, and the vacuum tube line 45 is installed in the vacuum tube line installation passage 51. There is.

The vacuum tube installation passage 51 is as shown in FIGS. 2 (a) and 2 (b) and FIG. 10 (a) (FIG. 10 (a) is a cross-sectional view taken along the line V3-V3 in FIG. 2 (b)) in the present embodiment. In addition, the transport passage 21L is composed of a lower half region of the upper and lower regions formed by being partitioned by the partition member 52. In the present embodiment, since the transport path 21L is partitioned by the partition member 52 in this way, the embossed portion EB of the carrier tape CT is not the original bottom surface 21M of the transport path 21L, but the upper surface of the partition member 52 as a guide surface. As 52M, the vehicle travels in the transport path 21L (with the bottom surface of the embossed portion EB in contact with the guide surface 52M).

10 (b) and 10 (c) show another example of how to provide the vacuum tube installation passage 51. FIG. 10 (b) is the same as in the case of FIG. 10 (a) in that the transport path 21L is composed of the lower half of the upper and lower regions formed by the partition member 52, but is the same as in the case of FIG. 10 (a). The width direction (X direction) dimension of the installation passage 51 is smaller than the width direction dimension of the transport path 21L. Therefore, the region of the vacuum tube 45 that can move in the vacuum tube installation passage 51 is limited as compared with the case of FIG. 10A, and the position of the vacuum tube 45 in the vacuum tube installation passage 51 can be stabilized.

FIG. 10C is an example in which the vacuum tube installation passage 51 is formed without partitioning the transport path 21L by the partition member 52, and the height of the transport path 21L is higher than that in the cases of FIGS. 10A and 10B. After lowering the height, a vacuum tube installation passage 51 as a dedicated passage for installing the vacuum tube 45 is formed below the transport path 21L. In FIG. 10C, the transport passage 21L and the vacuum pipeline installation passage 51 are vertically communicated with each other by the communication passage 53, and the dimension in the width direction (X direction) of the communication passage 53 is the width direction of the embossed portion EB. By making the size smaller than the size of the above, it is possible to prevent the embossed portion EB from falling into the vacuum pipeline installation passage 51 from the communication passage 53. It should be noted that the continuous passage 53 does not necessarily have to be provided.

In FIG. 2A, the rear end of the vacuum tube 45 installed in the vacuum tube installation passage 51 extends rearward (outside the frame 21) from the rear end of the frame 21, and the end thereof is It is connected to an extension portion 21E formed by extending downward from the rear portion of the frame 21 (FIG. 2A). The vacuum tube 45 extends from the rear of the frame 21 to the outside of the frame 21, but extends from below the inlet opening 21A formed in the frame 21 to the outside of the frame 21, so that it does not interfere with the carrier tape CT and is a carrier tape. It does not affect the transport of CT.

In FIG. 2A, a diffuser / speakon unit 21S is provided in the extending portion 21E, and the vacuum tube 45 is connected to the diffuser / speakon unit 21S. The diffuser / speakon unit 21S is a mechanism for converting positive pressure supplied from the outside of the tape feeder 14 through the pipeline VT into negative pressure.

When vacuum pressure is supplied to the internal space 44V of the suction block 44 through the diffuser / speed controller unit 21S and the vacuum tube 45, a suction force is generated in the upper region of the suction block 44 through the suction port 44S of the suction block 44. The diffuser / speed controller unit 21S is provided with a control knob 21C (FIG. 2A), and the operator operates the control knob 21C to switch the magnitude of the negative pressure in the upper region of the suction port 44S. The generated suction force can be changed.

When a suction force is generated in the upper region of the suction port 44S, the component BH in the embossed portion EB passing above the suction port 44S is provided with an air hole EH provided at the bottom of the embossed portion EB in which the component BH is housed. Pulled down through. Therefore, the component BH in the embossed portion EB is in close contact with the upper surface of the embossed portion EB, and the violence of the component BH in the embossed portion EB is suppressed.

In the present embodiment, the suction port 44S extends in the Y direction in a region including a fixed region on the upstream side of the component supply position 14K and the component supply position 14K, and travels in the region covered by the cover member 22. Of the component BHs in the tape CT, several component BHs approaching the component supply position 14K are drawn downward (FIG. 7). Therefore, when the component BH in the carrier tape CT reaches the component supply position 14K, the component BH has a stable posture in which the rampage in the embossed portion EB is suppressed.

As described above, the tape feeder 14 in the present embodiment includes a suction block 44 that generates a suction force in the suction port 44S provided on the upper surface 44a by supplying a vacuum pressure to the internal space 44V. By the block 44, the component BH in the carrier tape CT approaching the component supply position 14K is sucked (pulled) downward by the carrier tape CT being transported by the tape transport unit 23. As a result, the component BH in the embossed portion EB is suppressed from rampaging when it reaches the component supply position 14K, so that the mounting head 15 can reliably suck the component BH located at the component supply position 14K by the nozzle 15N. Is.

Further, in the tape feeder 14 of the present embodiment, the vacuum tube 45 for supplying the vacuum pressure to the suction block 44 is provided so as to extend below the transfer path 21L in the frame 21 along the transfer path 21L. It is configured to be installed in the passage 51. Therefore, the lateral dimension of the tape feeder 14 is the same as that without the suction block 44 (that is, without the vacuum tube 45), and is compact (slim) with the suction block 44 (and the vacuum tube 44). It has become a thing.

Next, the height adjustment of the suction block 44 will be described. In the present embodiment, a plurality of the above-mentioned spacers 43 are prepared in advance, and one or a plurality of spacers 43 are selected from the plurality of spacers 43 according to the thickness of the carrier tape CT. , Is installed below the suction block 44. The plurality of spacers 43 include those having different thicknesses, for example, five spacers having thicknesses of 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, and 1.0 mm. 43 is prepared.

FIG. 11 shows an example of a combination of the depth (referred to as embossing depth) of the embossed portion EB of the carrier tape CT conveyed by the tape feeder 14 and the spacer 43 used correspondingly thereof. In this example, a plurality of spacers 43 having different thicknesses (five spacers 43 having the above thicknesses of 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, and 1.0 mm) are combined. By stacking them vertically, the total thickness of the spacer 43 (referred to as the spacer thickness) can be set to the optimum thickness. Here, the "optimal thickness" is a suction force capable of sucking the component BH in the air hole EH by reducing the distance between the upper surface 44a, which is the suction surface of the suction block 44, and the bottom surface of the embossed portion EB of the carrier tape CT. It is a thickness (spacer thickness) for ensuring. The "optimal thickness" includes setting the spacer thickness to a height at which the upper surface 44a just contacts the bottom surface of the embossed portion EB of the carrier tape CT, but the upper surface 44a and the embossing are embossed as in the present embodiment. It is preferable to secure a slight gap between the bottom surfaces of the portion EB to reduce the resistance during transport of the carrier tape CT.

As described above, in the tape feeder 14 of the present embodiment, the carrier tape CT is provided by installing one or more spacers 43 selected from the plurality of spacers 43 prepared in advance below the suction block 44. The height of the suction block 44 can be adjusted according to the thickness of the embossed portion EB. Therefore, only one type of suction block 44 is required, and only a plurality of spacers 43 need to be prepared. Therefore, the height of the suction block 44 can be adjusted according to the thickness of the carrier tape CT with an inexpensive configuration. Can be done. Further, the height of the suction block 44 can be adjusted by a simple operation of replacing the spacer 43, so that the workability is good.

In the tape feeder 14 of the present embodiment, among the plurality of spacers 43 prepared in advance, the spacers 43 other than the spacer 43 installed below the suction block 44 are shown in FIGS. 12 (a) and 12 (b). As described above, the holding screw 62 can be attached to the spacer holding hole 61 as the spacer holding portion formed in the rear portion of the frame 21. Therefore, the unused spacer 43 can be held integrally with the frame 21, and the spacer 43 can be prevented from being lost. Further, since the spacer 43 that needs to be used can be quickly taken out, the height adjustment work of the suction block 44 can be performed in a short time.

As described above, in the tape feeder 14 included in the component mounting device 1 of the present embodiment, the vacuum tube 45 for supplying the vacuum pressure to the suction block 44 is provided in the transport path 21L below the transport path 21L in the frame 21. It is configured to be installed in the vacuum tube installation passage 51 extending along the line. Therefore, the lateral dimension of the tape feeder 14 is the same as that without the suction block 44 (that is, without the vacuum tube 45), and is compact (slim) with the suction block 44 (and the vacuum tube 45). Can be.

Although the embodiments of the present invention have been described so far, the present invention is not limited to the above-mentioned ones, and various modifications and the like are possible. For example, the shape of the suction block 44 shown in the above embodiment is an example, and a suction force is generated in the suction port 44S provided on the upper surface 44a by supplying a vacuum pressure to the internal space 44V, and the tape is conveyed. The shape and the like are not particularly limited as long as the component BH in the carrier tape CT approaching the component supply position 14K can be sucked downward by the transport of the carrier tape CT by the portion 23. Further, the suction block 44 may form a unit (suction block unit) together with the bracket 41, the base body 42 and the spacer 43, and may be attached to and detached from the frame 21 in the unit unit.

Further, in the above-described embodiment, the spacer 43 is held by attaching it to the spacer holding hole 61 by using the holding screw 62, but this is an example, and a storage space is formed in the frame 21. An unused spacer 43 may be stored in the storage space.

Further, in the above-described embodiment, the bracket 41 is provided in the area covered by the cover member 22 of the frame 21, and the suction block 44 is attached to the bracket 41 via the base body 42 and the spacer 43. However, the suction block 44 only needs to be able to suck the component BH in the carrier tape CT approaching the component supply position 14K downward by transporting the carrier tape CT by the tape transport section 23, and does not necessarily require the bracket 41 or the base body 42. is not. For example, a part of the frame 21 may be projected below the transport path 21L, and the suction block 44 may be attached to the protruding upper surface via the spacer 43. That is, a part of the frame 21 may be used as a pedestal for mounting the suction block 44. Further, the type (thickness) of the spacer 43 shown in the above-described embodiment is an example, and a spacer 43 having another thickness may be used. Further, the combination of the spacers 43 shown in FIG. 11 is only an example, and the spacers 43 may be assembled by a method different from that of FIG.

Although the carrier tape CT has been described as being an embossed type in the above-described embodiment, the present invention can also be applied to a carrier tape CT that is not an embossed type.
