Description

The present specification relates to tape autoloaders.

2. Description of the Related Art Conventionally, there is known an automatic tape loading device that loads a carrier tape into a tape feeder (see, for example, Patent Document 1). The carrier tape has a base tape provided with an accommodation portion for accommodating components, and a cover tape that closes the accommodation portion of the base tape. The cover tape is detachably attached to the base tape so that the components stored in the storage section can be taken out. The carrier tape is wound around a tape reel that can be attached to the tape feeder. The tape feeder pulls out the carrier tape from the mounted tape reel, and separates the cover tape from the base tape of the carrier tape so that the components in the storage section can be adsorbed at the component adsorption position. Also, the tape feeder sends out the cover tape separated from the base tape along a predetermined path and discharges it to the outside.

The automatic tape loading device includes a feeder holder, a conveying device, and a cover tape processing device. The feeder holding base is a pedestal that holds a tape feeder for loading the carrier tape. The conveying device is a device that conveys the carrier tape loaded in the tape feeder in the conveying direction. This conveying device can be slid in a direction approaching the tape feeder held on the feeder holding table while holding the carrier tape. The cover tape processing device is a device that uses a temporary tape to discharge the cover tape separated from the base tape of the carrier tape to the outside of the tape feeder.

WO2013/186848

In the above automatic tape loading device, when the tape feeder is held by the feeder holding base or is approached by the conveying device which slides after being held, the carrier tape is conveyed from the conveying device for loading into the tape feeder. An interfering member that interferes with the transport of the carrier tape may appear on the transport path. This interference member is, for example, a feeder clamp wire that pulls a holding member that holds the tape feeder on the feeder holding base, or a tape guide provided in the component supply portion of the tape feeder that moves upward when the carrier tape is loaded. It is a guide lever that rotates.

If the carrier tape is transported along the transport path as it is without taking any countermeasures when the interference member is present on the transport path, the carrier tape may interfere with the interference member and hinder its transport. In particular, since the carrier tape is generally traverse-wound around a reel, the tape is warped in the width direction, and the amount of warp in the width direction varies greatly depending on the location. For this reason, there is a possibility that the carrier tape may include a portion where it is easy to interfere with the interfering member and a portion where it is difficult to interfere, and there is a possibility that stable transport of the carrier tape may not be ensured.

SUMMARY OF THE INVENTION An object of the present specification is to provide an automatic tape loading device capable of preventing the carrier tape from interfering with an interference member in the process of loading the carrier tape into the tape feeder.

The present specification includes a feeder holding stand that holds a tape feeder, a carrier tape conveying device that loads the tape feeder held by the feeder holding stand, and a carrier tape that is held by the feeder holding stand. and a guide member that guides the carrier tape so that it does not interfere with a predetermined member that may hinder the transport of the carrier tape when the carrier tape is loaded into the tape feeder.

According to the present disclosure, when the carrier tape is loaded into the tape feeder held by the feeder holding base, the guide member provided in the automatic tape loading device causes the carrier tape to interfere with the conveyance of the carrier tape. It is guided so as not to interfere with the member. Therefore, it is possible to prevent the carrier tape from interfering with the predetermined members during the process of loading the carrier tape into the tape feeder.

Then, in the course of the transfer portion 72 rotating from the initial angle to the predetermined transfer completion angle, the leading end portion of the temporary tape 300 moves from the first position P1 corresponding to the second tape holding portion 143 of the tape feeder 100 to the tape feeder 100. 100 to the third position P3 corresponding to the first tape holding portion 133 of the tape feeder 100.

The first extrusion portion 73 is arranged on the front side of the body plate 71 . The first extrusion part 73 is rotatably supported by a rotation fulcrum 73a. The first extruding portion 73 is biased in one circumferential direction (clockwise direction shown in FIG. 9) about the rotation fulcrum 73a by a biasing member, and in the initial state, contacts the contact roller 72f of the transfer portion 72. maintained in condition. An inner support pin mechanism portion 73b and two guide pins 73c are attached to the front side of the first extrusion portion 73, respectively. The inner support pin mechanism portion 73b contacts and supports the temporary tape 300 from the inside. The inner support pin mechanism portion 73b has two support plates that are rotatable with respect to the first extrusion portion 73 about the rotation fulcrum 73a.

A pin for supporting the temporary tape 300 is attached to the tip of each of these support plates so as to protrude in the orthogonal direction Y. As shown in FIG. Each of these pins is rotatable around a rotation fulcrum 73a and is connected by a tension spring. The initial spacing between the two pins is maintained at a predetermined spacing by the elastic force of the tension spring. The initial distance is the distance between the pins when the relative angular deviation of the two support plates about the rotation fulcrum 73a is, for example, about 90 degrees.

The second extrusion portion 74 is arranged on the front side of the body plate 71 . The second extrusion part 74 is rotatably supported by a rotation fulcrum 74a. The second push-out portion 74 is urged in one circumferential direction (clockwise direction in FIG. 9) about a rotation fulcrum 74a by an elastic member (not shown). 72f is maintained in a predetermined phase state. Two guide pins 74b are arranged on the front side of the second extrusion portion 74 . Each guide pin 74b contacts and supports the temporary tape 300 from the inside.

When the transfer portion 72 transfers the leading end portion of the temporary tape 300, the first extruding portion 73 and the second extruding portion 74 contact the contact rollers 72e and 72f at the back portions formed in the curved surfaces, respectively, and move in the circumferential direction. It rotates in the other direction (counterclockwise direction shown in FIG. 9). In this case, the inner support pin mechanism portion 73b and the guide pins 73c of the first extrusion portion 73 and the guide pins 74b of the second extrusion portion 74 move to the outer peripheral side of the body plate 71. As shown in FIG. That is, the first pushing part 73 and the second pushing part 74 push out part of the temporary tape 300 pulled by the transfer of the transfer part 72 to the outer peripheral side in conjunction with the rotation of the transfer part 72 . As a result, the first extrusion section 73 arranges the temporary tape 300 along a path following the transfer path of the cover tape 220 . In addition, the second extruded portion 74 forms a facing portion that faces the tip portion of the cover tape 220 at a portion of the temporary tape 300 that is connected to the cover tape 220 .

In the temporary tape arrangement device 70, in the initial state (that is, in a state where the rotation angle about the rotation fulcrum 72a of the transfer section 72 is zero), as shown in FIG. The first extruded portion 73 and the second extruded portion 74 are each maintained at the initial angle while gripping the tip of the temporary tape 300 protruding from the temporary tape support roller 71e.

Then, when the transfer portion 72 is driven to rotate from the initial state, the temporary tape 300 gripped by the gripping claws 72b is sequentially pulled out from the temporary tape reel 310 by tension, and the leading end of the temporary tape 300 is pulled out from the pair of temporary tape support rollers. Starting from 71e, it is transferred via the first position P1 and the second position P2. Then, when the transfer portion 72 rotates about 140°, the contact rollers 72e and 72f of the transfer portion 72 contact the first pushing portion 73 and the second pushing portion 74 to interlock with each other, as shown in FIG. At this time, the inner support pin mechanism portion 73b and the guide pin 73c of the first extrusion portion 73 gradually push out the temporary tape 300 to the outer peripheral side. The second extrusion part 74 is interlocked by the contact roller 72f, but is in a non-contact state with the temporary tape 300 at this stage.

Further, when the transfer section 72 is rotationally driven to rotate about 165° from the initial state, the leading end of the temporary tape 300 is moved to the third position P3 as shown in FIG. When such processing is executed, the temporary tape 300 is pulled out by the transfer section 72 to a position corresponding to the first tape holding section 133 of the tape feeder 100 . A part of the temporary tape 300 stretched by the transfer is further pushed out by the first pushing part 73, and the temporary tape 300 is routed and molded in a shape along the route following the discharge route of the cover tape 220. be done.

More specifically, the temporary tape 300 is formed into an S-shaped curved shape by the outer support pin mechanism portion 71d of the body plate 71 and the inner support pin mechanism portion 73b of the first extrusion portion 73 . At this time, the inner support pin mechanism portion 73b is maintained by the tension spring such that the distance between the two pins is the initial distance. Then, in a state in which the transfer portion 72 has been rotated about 165° from the initial state, as shown in FIG. While being extruded, it is molded into a U-shape so as to face the cover tape 220 when it is connected to the cover tape 220 later. In this way, the temporary tape arrangement device 70 rotates the transfer unit 72 to interlock the first extrusion unit 73 and the second extrusion unit 74, and forms the temporary tape 300 into a predetermined shape that follows the discharge route. It is routed and held along the path of the predetermined shape.

The connecting device 80 removes the temporary tape 300 held by the temporary tape arrangement device 70 as described above from the base tape 210 of the carrier tape 200 in the first tape holding portion 133 of the tape feeder 100 and separates the cover tape 220 from the cover tape 220 . It is a device that connects to the tip side. The coupling device 80 has a heating element 82 . The heating member 82 can be heated up to a predetermined temperature (for example, 170° C.) by control. The connection between the cover tape 220 and the temporary tape 300 by the connecting device 80 is performed by heat bonding using the heating member 82 .

The heating member 82 is a member that heats and adheres the cover tape 220 and the temporary tape 300 by sandwiching the front end of the cover tape 220 and the front end of the temporary tape 300 with the tape pressing member. The heating member 82 is attached to the main body plate 71 of the temporary tape arrangement device 70 fixed to the pedestal 61 so as to overlap the rotation position of the second extrusion portion 74 of the temporary tape arrangement device 70 . The heating member 82 is separated from the tape pressing member before the heat bonding, and is moved until it comes into contact with the tape pressing member when the heat bonding is requested.

The transfer device 90 is a device that transfers the temporary tape 300 connected to the tip of the cover tape 220 from the temporary tape arrangement device 70 to the tape feeder 100 . The transfer device 90 controls the operation of the temporary tape arrangement device 70 and the operation of the second release device 50 to transfer the temporary tape 300 .

Next, the operation of the automatic tape loading device 1 will be described with reference to FIGS. 13 to 23. FIG.
In the automatic tape loading device 1, in the initial state, as shown in FIG. are separated from the feeder holding table 10 in the orthogonal direction Y with a predetermined distance. Further, the provisional tape arrangement device 70 of the cover tape processing device 60 previously forms and holds the provisional tape 300 in a shape following the discharge route of the cover tape 220 by the operation described above. It is sufficient that the temporary tape 300 is formed or held by the temporary tape arrangement device 70 before it is connected to the cover tape 220 by the connecting device 80. For example, at the same time as the carrier tape 200 is conveyed by the tape feeder 100. may be done.

In the initial state described above, the operator sets the tape feeder 100 on the feeder holder 10 . Specifically, the bottom surface of the feeder main body 110 is mounted between the pair of support guides 13 on the mounting portion 11 and sandwiched therebetween, and the positioning pins and communication connector of the feeder main body 110 are positioned on the positioning portion 15 of the contact portion 12 and the communication connector. Each is inserted into the communication jack 14 . Then, the tape reel 240 is attached to the reel accommodating section 120, and a feeder setting completion button provided as a control device of the automatic tape loading device 1 is pressed.

When the feeder setting completion button is pressed, the first tape conveying device 20 and the second tape conveying device 30 are slid in the orthogonal direction Y to approach the feeder holder 10 by control. Then, as shown in FIG. 13, the first tape conveying device 20 and the second tape conveying device 30 each determine that the position of the guides 21 and 31 in the orthogonal direction Y is the same as the position of the tape feeding guide 111 of the tape feeder 100 in the orthogonal direction Y. Positioned to be equal.

Further, the first opening device 40 is slid in the orthogonal direction Y as the second tape conveying device 30 slides. In this case, the first lift lever 41 of the first opening device 40 is inserted into the lever 138 of the first tape holding portion 133 of the tape feeder 100 on the operation permitting side. Then, when the support base 42 of the first opening device 40 is lifted in the vertical direction Z by control, the first lift lever 41 lifts the lever 138 of the first tape holding portion 133 . When the lever 138 is lifted, the first tape holding portion 133 rotates upward around the rotation fulcrum 133a, so that there is a gap between the first tape holding portion 133 and the sprocket 131 into which the carrier tape 200 can be inserted. It is formed.

Here, the operator pulls out the carrier tape 200 from the tape reel 240 accommodated in the reel accommodation unit 120, and the leading end of the carrier tape 200 (specifically, the leading end of the cover tape 220) is conveyed as the first tape. It is inserted into the rear end of guide 21 of device 20 . When such insertion is performed, the gear motors 24 and 33 and the motor 132 are driven after the tip of the cover tape 220 is detected by a sensor (not shown). When the motors 24, 33, 132 are driven, the carrier tape 200 is fed in the transport direction X and guided by the guides 21, 31 and the tape feed guide 111, and the gap between the first tape holding portion 133 and the sprocket 131 is reached. is transported to a position where it passes through

When the carrier tape 200 is conveyed to the first tape holding portion 133, the motors 24, 33, 132 are stopped, and the support base 42 and the first lift lever 41 of the first opening device 40 are lowered by control. , the lever 138 of the first tape holding portion 133 is lowered. When the lever 138 is lowered, the first tape holding portion 133 rotates downward around the rotation fulcrum 133 a , so that the carrier tape 200 is held between the first tape holding portion 133 and the sprocket 131 . When the motor 132 is driven in such a state, the sprocket 131 is rotated, and the carrier tape 200 is conveyed so that the leading end thereof protrudes from the first tape holding portion 133 in the conveying direction X by a predetermined amount. .

Subsequently, as shown in FIG. 14, each of the first tape conveying device 20 and the second tape conveying device 30 is slid in the orthogonal direction Y away from the feeder holder 10 . Further, the second opening device 50 is slid in the orthogonal direction Y to approach the feeder holder 10 . In this case, the second lift lever 51 of the second opening device 50 is inserted into the lever 146 of the second tape holding portion 143 of the tape feeder 100 on the operation permitting side. Then, when the support table 52 of the second opening device 50 is moved in the conveying direction X by control, the arm 145 of the second tape holding portion 143 is moved by the second lift lever 51 to the rotation fulcrum 145a at the rear end side of the feeder main body 110. is rotated around the In this case, since the gear 144 of the second tape holding portion 143 is separated from the gear 141 of the cover tape delivery mechanism portion 140, the holding state between the gear 144 and the gear 141 is released.

With the gear 144 and the gear 141 of the cover tape delivery mechanism 140 opened, the cover tape processing device 60 is slid in the orthogonal direction Y to approach the feeder holder 10 . At this time, the temporary tape arrangement device 70 is in a state in which the temporary tape 300 is shaped in advance into a shape along the path following the ejection path of the cover tape 220 and is held. Then, the cover tape processing device 60 makes the position of the temporary tape 300 held by the temporary tape arrangement device 70 in the orthogonal direction Y equal to the position of the carrier tape 200 held by the tape feeder 100 in the orthogonal direction Y. positioned to be

As shown in FIG. 15, this positioning is such that the leading end of the temporary tape 300 is positioned below the leading end of the cover tape 220 protruding from the first tape holding portion 133 of the tape feeder 100 in the conveying direction X side. The tip of the temporary tape 300 is made to face the tip of the tape 220 . In addition, the portion of the temporary tape 300 positioned between the two guide pins 73c of the first extrusion portion 73 is located between the gear 141 of the cover tape delivery mechanism portion 140 and the gear 144 of the second tape holding portion 143, which are separated from each other. positioned to pass through the Furthermore, the portion of the temporary tape 300 curved in an S shape by the outer support pin mechanism portion 71d and the inner support pin mechanism portion 73b is located between the two guide rollers 151 and 152 of the cover tape feed guide 150 in the tape feeder 100. positioned to pass through the

After the above positioning is performed, the leading end of the cover tape 220 projecting in the transport direction X side from the first tape holding portion 133 of the tape feeder 100 is gripped. After the gripping, the heating member 82 of the connecting device 80 is moved until it comes into contact with the lower surface of the tape holding member, so that the cover tape 220 and the temporary tape 300 are sandwiched while overlapping each other. Then, the cover tape 220 and the temporary tape 300 are heated by the heating member 82 . When such heating is performed, the adhesive remaining on the peeling surface of the cover tape 220 when it is peeled off from the base tape 210 is softened by the heat treatment and functions as an adhesive again. are adhered to each other by an adhesive at a portion sandwiched by the connecting device 80 .

After the cover tape 220 and the temporary tape 300 are connected to each other, the heating member 82 is separated from the tape pressing member. Further, the gripping of the temporary tape 300 by the gripping claws 72b of the transfer section 72 is released. After that, the temporary tape 300 held by the temporary tape arrangement device 70 is transferred to the tape feeder 100 .

When the temporary tape 300 is transferred to the tape feeder 100 , the transfer device 90 operates the second opening device 50 to hold the temporary tape 300 . When this operation is performed, the support base 52 of the second opening device 50 is moved in the conveying direction X by the urging force of the coil spring 147, so that the arm 145 of the second tape holding portion 143 moves toward the front end side of the feeder main body 110. It rotates around the rotation fulcrum 145a. In this case, the temporary tape 300 is held between the gear 144 of the second tape holding portion 143 and the gear 141 of the cover tape delivery mechanism portion 140 .

Then, the cover tape processing device 60 cuts the temporary tape 300 between the second tape holding section 143 and the temporary tape reel 310 by a tape cutter (not shown). After this cutting, the temporary tape 300 is transferred to the tape feeder 100 as shown in FIG. At this time, the temporary tape 300 may interfere with the carrier tape 200 that is being conveyed. 200 can be prevented.

After the cutting, the cover tape processing device 60 is moved in the orthogonal direction Y away from the feeder holder 10 . Further, after the above cutting, the transfer portion 72 is returned to the initial angle. Further, the motor 132 is driven to rotate the sprocket 131 , thereby locating the component accommodated in the base tape 210 and positioning it at the component suction position L. As described above, automatic setting of the carrier tape 200 to the tape feeder 100 by the automatic tape loading device 1 is completed.

In the automatic tape loading device 1 described above, the first tape conveying device 20 and the second tape conveying device 30 transport the carrier from the reel accommodating section 120 accommodating the tape reel 240 to the tape feeding mechanism section 130 via the tape feeding guide 111 . Tape 200 can be transported. Further, by the cover tape processing device 60, the temporary tape 300 is heat-bonded to the cover tape 220 of the carrier tape 200 and transferred to the tape feeder 100, so that the cover tape 220 is transferred along the discharge path to the feeder main body 110. can be discharged to the outside of the That is, the carrier tape 200 can be automatically loaded into the tape feeder 100 .

By the way, in the automatic tape loading device, when the tape feeder 100 is held by the feeder holding base 10 or is approached by the conveying devices 20 and 30 which have slid after being held, the carrier tape 200 is pulled from the first tape conveying device 20. On the tape feed guide 111 as the tape transport path transported for loading into the feeder 100, an interfering member that can interfere with transport of the carrier tape 200 appears. In particular, since the carrier tape 200 is highly likely to be warped in the tape width direction, interference with the interfering member is likely to occur.

One of the interference members is a feeder clamp wire 5 that pulls a holding member that holds the tape feeder 100 on the feeder holding table 10, as shown in FIG. The feeder clamp wire 5 extends along the transport direction X on one end side of the tape feed guide 111 in the orthogonal direction Y where the carrier tape 200 is transported (for example, on the left side when facing the transport direction X as shown in FIG. extended. Further, as one of the above interference members, for example, as shown in FIG. There is a lever 138 that rotates 133 upward when the carrier tape 200 is loaded. The lever 138 is arranged on one end side of the tape feed guide 111 in the orthogonal direction Y (for example, on the left side when facing the transport direction X as shown in FIG. 17).

On the other hand, the automatic tape loading device 1 causes the carrier tape 200 transported between the guides 21 and 31 and the tape feed guide 111 to interfere with the interference member (marked with "x" in FIGS. 16 and 17). A guide member 400 is provided for guiding so that interference at the location indicated by ) does not occur. The guide member 400 consists of a first guide member 410 for preventing interference between the carrier tape 200 and the feeder clamp wire 5 as shown in FIGS. and a second guide member 420 that prevents interference.

The first guide member 410 is attached to the first tape conveying device 20 as shown in FIG. The first guide member 410 is formed and arranged so as to cover the tape feed guide 111 from above when the first tape conveying device 20 is close to the tape feeder 100 held by the feeder holding table 10 . The first guide member 410 is arranged upstream in the transport direction from a position where the carrier tape 200 can interfere with the feeder clamp wire 5 (hereinafter referred to as a wire interference position). It is preferable that the end of the first guide member 410 on the downstream side in the transport direction is close to the wire interference position where the carrier tape 200 can interfere with the feeder clamp wire 5 in order to avoid such interference.

As shown in FIGS. 20 and 21, the first guide member 410 guides the carrier tape 200 in the tape width direction (that is, the orthogonal direction Y) opposite to the side where the feeder clamp wire 5 exists (for example, the transport direction X). to the right). The first guide member 410 has a mounting portion 411 , a top guide portion 412 and a slope portion 413 .

The attachment portion 411 is a bracket portion attached to the first tape transport device 20 . The mounting portion 411 is formed so that a bolt or the like for fastening with the first tape conveying device 20 can be inserted. The upper surface guide portion 412 is a portion integrally connected to the mounting portion 411, and is arranged above the tape feed guide 111 with a predetermined gap in a state where the first tape conveying device 20 is approaching the tape feeder 100. be done. Note that the gap may gradually decrease from the upstream side to the downstream side in the conveying direction. The upper surface guide portion 412 is a guide portion that guides the carrier tape 200 guided along the tape feeding guide 111 while abutting or supporting the upper surface thereof. The top guide portion 412 extends in the transport direction X substantially parallel to the tape feed guide 111 and has substantially the same width as the width in the orthogonal direction Y of the tape feed guide 111 .

The slope portion 413 is a portion that prevents the carrier tape 200 conveyed on the tape feed guide 111 from leaning toward the side where the feeder clamp wire 5 exists in the orthogonal direction Y (for example, the left side when facing the conveying direction X). is. The slope portion 413 extends obliquely downward from the upper surface guide portion 412 toward the side where the feeder clamp wire 5 exists. Specifically, the slope portion 413 extends obliquely downward from the end of the upper surface guide portion 412 on the side where the feeder clamp wire 5 exists in the orthogonal direction Y, and the lower position is further inclined in the orthogonal direction Y than the upper position. is positioned on the side where the feeder clamp wire 5 is present. The slope portion 413 extends to such an extent that its lower end contacts the tape feed guide 111 .

In addition, it is desirable that the sloped portion 413 is formed so as to be located in the outer region opposite to the inner region where the carrier tape 200 is conveyed with the feeder clamp wire 5 interposed therebetween. The slope portion 413 may be a portion integrally connected to the upper surface guide portion 412, or may be provided separately from the upper surface guide portion 412 and attached and fixed to the upper surface guide portion 412. good too.

Incidentally, the first tape conveying device 20 may be provided with a guide assisting member 415 as shown in FIG. The guide assisting member 415 is arranged on the opposite side of the first guide member 410 from the slope portion 413 with the top guide portion 412 interposed therebetween. The guide assisting member 415 is a wall member erected against the tape feeding guide 111 . The guide assisting member 415 sandwiches the carrier tape 200 in the tape width direction between the slanted portion 413 and guides the side surface of the carrier tape 200 opposite to the side on which the feeder clamp wire 5 exists in the orthogonal direction Y. . The minimum value of the separation distance in the orthogonal direction Y between the guide assisting member 415 and the slope portion 413 is set to be equal to or greater than the tape width of the carrier tape 200 .

In the structure of the automatic tape loading device 1 described above, in a state in which the first tape conveying device 20 is approaching the tape feeder 100 held on the feeder holding base 10, the upper guide portion 412 of the first guide member 410 is It is arranged above the tape feed guide 111 of the tape feeder 100 . Further, on the upstream side of the wire interference position in the transport direction, the inclined surface portion 413 is arranged so as to extend obliquely downward from the upper surface guide portion 412 of the tape feed guide 111 on the side where the feeder clamp wire 5 exists in the orthogonal direction Y.

According to this structure, when the carrier tape 200 is loaded, the slope portion 413 of the first guide member 410 exists on the side of the tape feed guide 111 in the orthogonal direction Y where the feeder clamp wire 5 exists. The guide prevents the carrier tape 200 from leaning toward the side of the feeder clamp wire 5 in the orthogonal direction Y as indicated by the broken line in FIG. 21 (the carrier tape 200 is indicated by the solid line in FIG. 21). In particular, when the carrier tape 200 is conveyed along the tape feeding guide 111 while being supported by the upper surface guide portion 412 , the carrier tape 200 is guided by the upper side of the slope portion 413 to feed the tape feeding guide 111 in the orthogonal direction Y. Since the carrier tape 200 tends to lean to the side opposite to the side where the clamp wire 5 exists, the carrier tape 200 is reliably prevented from leaning to the side in the orthogonal direction Y where the feeder clamp wire 5 exists.

If the carrier tape 200 is conveyed in the conveying direction X in a state in which the first guide member 410 prevents the carrier tape 200 from deviating to the side where the feeder clamp wire 5 exists in the orthogonal direction Y, the carrier tape 200 on the tape feed guide 111 is corrected to the side opposite to the side in the orthogonal direction Y where the feeder clamp wire 5 exists. Therefore, the carrier tape 200 is less likely to interfere with the feeder clamp wire 5 located downstream of the first guide member 410 in the conveying direction.

Therefore, it is possible to prevent the carrier tape 200 from interfering with the feeder clamp wire 5 in the process of loading the carrier tape 200 into the tape feeder 100 by the automatic tape loading device 1, thereby preventing the transport of the carrier tape 200 from being hindered. can be avoided. In particular, even if the carrier tape 200 is warped in the tape width direction due to traverse winding on the tape reel 240, the carrier tape 200 is less likely to interfere with the feeder clamp wire 5. Stable transportation can be ensured, and workability can be improved, or the operating rate of the apparatus can be improved.

22, the second guide member 420 is attached to the second tape conveying device 30. As shown in FIG. The second guide member 420 protrudes from the second tape transport device 30 side to the upper surface of the tape feed guide 111 in a state where the second tape transport device 30 is close to the tape feeder 100 held by the feeder holding base 10. are arranged in such a way that The projecting tip of the second guide member 420 is extended from the boundary position (indicated by the chain double-dashed line in FIG. 23) S of the position where interference with the carrier tape occurs in the lever 138 and the position where interference does not occur. Positioning on the non-interfering side is desirable to avoid that interference.

The second guide member 420 is arranged upstream in the transport direction from a position where the carrier tape 200 can interfere with the lever 138 (hereinafter referred to as a lever interference position). It is preferable that the end of the second guide member 420 on the downstream side in the transport direction be close to the lever interference position where the carrier tape 200 can interfere with the lever 138 in order to avoid that interference. Further, the position where the second guide member 420 protrudes from the tape feed guide 111 of the tape feeder 100 may be a position where the tape feeder 100 itself does not have a guide member for guiding the side surface of the carrier tape 200 .

The second guide member 420 guides the carrier tape 200 to the opposite side of the lever 138 in the tape width direction (that is, the orthogonal direction Y) (for example, to the right side when facing the transport direction X). invite. The second guide member 420 has a side surface extending along the transport direction X. As shown in FIG. The second guide member 420 has a tapered portion 421 that is inclined with respect to the transport direction X, and a support portion 422 that forms side surfaces parallel to the transport direction X. As shown in FIG.

The tapered portion 421 is inclined so as to narrow the path width of the tape feed guide 111 from the upstream side in the feeding direction of the tape feeding guide 111 to the downstream side in the feeding direction. The angle of inclination of the tapered portion 421 is set to an angle that allows the carrier tape 200 to easily move in the transport direction X while being shifted in the tape width direction without being caught after coming into contact with the tapered portion 421 . The tapered portion 421 abuts on the leading end corner portion of the carrier tape 200 conveyed from the upstream side in the conveying direction, and conveys the carrier tape 200 while moving the carrier tape 200 toward the side opposite to the side where the lever 138 exists in the tape width direction. .

The support portion 422 is positioned on the downstream side of the tapered portion 421 in the conveying direction and is formed integrally with the tapered portion 421 . The support portion 422 contacts the side surface of the carrier tape 200 conveyed from the upstream side in the conveying direction, and conveys the carrier tape 200 in parallel along the conveying direction X while supporting the side surface of the carrier tape 200 .

The tape feed guide 111 is formed so that the narrowest portion (specifically, the support portion 422 ) of the tape feed guide 111 is wider than the tape width of the carrier tape 200 . Moreover, as shown in FIG. 23, two or more sets of one taper portion 421 and one support portion 422 may be provided apart from each other in the transport direction X. As shown in FIG.

Incidentally, the second tape conveying device 30 or the first tape conveying device 20 may be attached with a guide assisting member 425 as shown in FIG. The guide assisting member 425 is arranged on the side opposite to the second guide member 420 with the tape feeding guide 111 interposed therebetween. The guide auxiliary member 425 sandwiches the carrier tape 200 in the tape width direction between itself and the second guide member 420, and guides the side surface of the carrier tape 200 opposite to the side where the lever 138 exists in the orthogonal direction Y. . The minimum distance between the guide assisting member 425 and the second guide member 420 in the orthogonal direction Y is set to be equal to or greater than the tape width of the carrier tape 200 .

In the structure of the automatic tape loading device 1 described above, in a state in which the second tape transport device 30 is approaching the tape feeder 100 held by the feeder holding table 10, the second tape feeding device 30 is upstream of the lever interference position in the transport direction. The second guide member 420 is arranged so as to protrude from the side edge of the tape feed guide 111 toward the upper surface thereof. In this arrangement, the second guide member 420 hides the lever 138 when viewed from the upstream side of the second guide member 420 in the transport direction.

According to this structure, when the carrier tape 200 is loaded, the second guide member 420 is present on the side of the tape feed guide 111 in the orthogonal direction Y where the lever 138 is present. 200 is prevented from deviating to the side of the orthogonal direction Y on which the lever 138 resides. If the carrier tape 200 is conveyed in the conveying direction X in a state in which the second guide member 420 prevents the carrier tape 200 from deviating to the side where the lever 138 exists in the orthogonal direction Y, the carrier tape 200 is conveyed on the tape feeding guide 111. The position is corrected to the side opposite to the side on which the lever 138 exists in the orthogonal direction Y along the path indicated by the hatched arrows in FIG. For this reason, the carrier tape 200 is less likely to interfere with the lever 138 located downstream of the second guide member 420 in the transport direction.

Therefore, in the process of loading the carrier tape 200 into the tape feeder 100 by the automatic tape loading device 1, the carrier tape 200 can be prevented from interfering with the lever 138, and the transportation of the carrier tape 200 can be avoided. can do. In particular, even if the carrier tape 200 is warped in the tape width direction due to traverse winding on the tape reel 240, the carrier tape 200 is less likely to interfere with the lever 138, so that the carrier tape 200 is stabilized. Conveyance can be ensured, and workability can be improved, or the operating rate of the device can be improved.

Further, the guide member 400 guides the carrier tape 200 so as not to interfere with the interfering member. and the second tape transport device 30 . This guide member 400 is integral with the first tape transport device 20 and the second tape transport device 30, and when the transport devices 20 and 30 approach the tape feeder 100 held on the feeder holding table 10, a predetermined is placed at the guide position of Therefore, when the carrier tape 200 is loaded into the tape feeder 100, it is not necessary to provide a dedicated mechanism for moving the guide member 400 to position the guide member 400 at a predetermined guide position. Therefore, interference prevention between the carrier tape 200 and the interference member using the guide member 400 can be realized with a simple configuration and at low cost.

In the above embodiment, both the feeder clamp wire 5 and the lever 138 are mentioned as interference members with which the carrier tape 200 interferes when the carrier tape 200 is loaded into the tape feeder 100 . However, the present disclosure is not so limited. Either one of the feeder clamp wire 5 and the lever 138 may be used as the interference member, or another member may be used.

Note that the present disclosure is not limited to the above-described embodiments and modifications, and various modifications can be made without departing from the scope of the present disclosure.
