Description

Tape guide and parts feeder

This specification relates to tape guides and component supply devices.

Conventionally, a tape guide provided in a component supply device is known (see Patent Document 1, for example). A component supply device is a device that supplies electronic components to a component supply position by transporting a carrier tape in a transport direction while electronic components are accommodated in a cavity of the carrier tape. The carrier tape has a base tape provided with a cavity, and a cover tape provided on the surface of the base tape to close the cavity of the base tape.

The tape guide includes a guide main body portion that guides the carrier tape when the carrier tape is conveyed in the conveying direction, and a tongue portion that is inserted between the base tape and the cover tape to expose the electronic components in the cavity. have. The tongue is fixed to the guide main body by welding or the like, and extends in the counter-conveying direction opposite to the conveying direction. The tongue portion is arranged such that its tip portion is fixed at a height position where it is inserted between the base tape and the cover tape of the carrier tape guided by the guide body portion. After the tongue is inserted between the base tape and the cover tape, the blade then cuts and splits the cover tape, thereby exposing the electronic components in the cavity.

JP 2016-26415 A

By the way, in the tape guide described in Patent Document 1, as described above, the tongue is fixed to the guide main body, and the tip of the tongue is inserted between the base tape and the cover tape of the carrier tape. It is fixed at a height position (hereinafter referred to as an insertion height position). Therefore, even after the tip of the carrier tape in the transport direction reaches the tip of the tongue while the carrier tape is being transported and the tip of the tongue is inserted between the base tape and the cover tape, the tip of the tongue is Since the bottom surface of is kept in contact with the top surface of the base tape, the corners of the tip of the tongue are more likely to come into contact with the electronic components in the cavity of the base tape.

On the other hand, in order to make it difficult for the electronic parts in the base tape cavity to come into contact with the corners of the tip of the tongue, a structure is considered in which the tip of the tongue is fixed at a position higher than the above insertion height position. be done. However, with this structure, it becomes difficult to insert the tip of the tongue between the base tape and the cover tape at the tip of the carrier tape in the conveying direction, thus properly exposing the electronic components in the cavity of the base tape. may become difficult.

Therefore, in order to avoid the above inconvenience, it is conceivable to have a structure in which the tip of the tongue can be moved vertically between a high position and a low position lower than the high position. In such a structure, the tip of the tongue is moved from the high position to the low position, and is inserted between the base tape and the cover tape at the tip of the carrier tape in the conveying direction. When the tip is moved from the low position to the high position and the carrier tape is transported, the tip of the tongue is appropriately inserted between the base tape and the cover tape, and after that insertion, the tip of the tongue is moved. can be avoided from contacting electronic components in the cavities of the base tape.

In the structure in which the tip of the tongue can be moved vertically between the high position and the low position, the tip of the tongue can be accurately moved when the tip of the tongue is moved from the high position to the low position. In order to fix the position at the low position, it is preferable to provide a stopper portion with which the tongue abuts and movement is restricted when the tip of the tongue reaches the low position.

However, depending on the type of carrier tape and the state of the tip in the transport direction, the height of the boundary between the base tape and the cover tape at the tip in the transport direction of the carrier tape being transported is not limited to a constant height and may fluctuate up and down. Therefore, the structure in which the low position of the tip of the tongue when the tongue contacts the stopper is limited to one height position cannot be applied to various carrier tapes and lacks versatility. , workability is reduced. On the other hand, by changing the magnitude of the force pushing down the tongue from above, it is possible to adjust the low position of the tip of the tongue when the tongue contacts the stopper without limiting to one position. , the tip of the tongue cannot be stably fixed in a low position.

In this specification, by changing the tip height of the tip of the tongue regardless of the magnitude of the force pushing down the tongue from above, the tip of the tongue can be used as a base tape to correspond to various carrier tapes. An object of the present invention is to provide a tape guide and a component supply device that can be appropriately inserted between a cover tape.

In this specification, a carrier tape having a base tape provided with a cavity for storing electronic components and a cover tape provided on the surface of the base tape so as to close the cavity is transported in the transport direction. a guide main body portion for guiding; and a tongue portion that is elastically deformable cantilevered by applying an external force from above to the guide main body portion and is inserted between the base tape and the cover tape during transport of the carrier tape. and a stopper portion that is disposed below the tongue portion and abuts against the tongue portion when the tongue portion is elastically deformed beyond a predetermined level, wherein the stopper portion and the tongue portion are arranged on the upper surface of the tongue portion. Disclosed is a tape guide formed so that the tip height of the tongue portion when the tongue portion abuts against the stopper portion changes depending on the external force application position at which the external force is applied.

According to the present disclosure, the tip height of the tongue when the tongue contacts the stopper can be changed according to the external force applying position on the upper surface of the tongue. Therefore, by changing the tip height of the tip of the tongue regardless of the magnitude of the force pushing down the tongue from above, the tip of the tongue can be used as a base tape or a cover tape to correspond to various carrier tapes. can be properly inserted between

A plurality of feed holes 85 are provided along the longitudinal direction of the tape, and are arranged in a row at predetermined intervals. The cavities 83 and the feed holes 85 are arranged in two rows in the width direction of the tape and along the longitudinal direction of the tape.

The cover tape 82 is releasably adhered to the surface of the base tape 81 . The cover tape 82 is adhered to both end portions in the width direction of the base tape 81 except for the central portion in the width direction of the tape where the cavity 83 is provided. The cover tape 82 is adhesively fixed to the base tape 81 to cover and close the opening of the cavity 83 . The cover tape 82 has a function of preventing the electronic component 2 housed in the cavity 83 from protruding to the outside. The cover tape 82 is made of a transparent polymer film or the like.

The cover tape 82 may have a tape width substantially the same as the tape width of the base tape 81. For example, as shown in FIG. The tape width of the base tape 81 may be smaller than that of the base tape 81 . Also, the tape width of the cover tape 82 may vary according to the type of the carrier tape 80 , that is, the tape width of the base tape 81 .

The tape transport path 31 is a transport path for transporting the carrier tape 80 pulled out from the tape reel 89 toward the component supply position P. The tape transport path 31 is provided inside the cassette case 10 . The tape transport path 31 linearly extends from the outlet of the carrier tape 80 in the tape reel 89 toward the component supply position P. As shown in FIG. The tape transport path 31 contacts and supports the lower surface of the carrier tape 80 . The tape conveying path 31 is formed to have an inclined portion that gradually rises from the upstream side to the downstream side in the conveying direction X, and a horizontal portion that extends horizontally at the most downstream portion.

The backup leaf spring 32 is a spring body that supports the lower surface of the carrier tape 80 (specifically, the base tape 81) on the tape transport path 31. The backup leaf spring 32 urges the carrier tape 80 on the tape transport path 31 upward to generate an urging force that presses the upper surface of the carrier tape 80 against a tape guide 50 which will be described later. The backup leaf spring 32 is provided inside the cassette case 10 and arranged downstream in the transport direction X with respect to the tape transport path 31 . The backup leaf spring 32 extends in the transport direction X along the tape transport path 31 and is elastically deformably supported by the cassette case 10 at one end.

The support leaf spring 33 is a spring body that supports the lower surface of the lower wall of the cavity 83 of the carrier tape 80 when the carrier tape 80 on the tape transport path 31 is an embossed tape. The support plate spring 33 generates a force that prevents the lower wall of the cavity 83 of the carrier tape 80 on the tape transport path 31 from dropping under its own weight.

It is a device that allows Component exposure device 40 includes a tape guide 50 .

The tape guide 50 is a member that guides the carrier tape 80 conveyed on the tape conveying path 31 . The tape guide 50 is arranged downstream in the transport direction X of the tape transport path 31 . The tape guide 50 is supported at the front end of the cassette case 10 so as to be vertically swingable. The tape guide 50 can hold the upper surface of the carrier tape 80 on the tape transport path 31 . In particular, the tape guide 50 is urged and pressed downward against the cassette case 10, and even if the tape thickness of the carrier tape 80 changes, the carrier tape 80 is lifted by pressing the upper surface of the carrier tape 80. It is possible to reliably engage the feed hole 85 with the sprocket.

The tape guide 50 can insert a later-described tongue portion 52 between the base tape 81 and the cover tape 82 of the carrier tape 80 while pressing the upper surface of the carrier tape 80 on the tape transport path 31 . At the same time, it is possible to peel off the cover tape 82 from the base tape 81 just before the component supply position P to expose the electronic component 2 in the cavity 83 . As shown in FIGS. 4, 5, 6, 7, 8, 9, and 10, the tape guide 50 includes a guide body portion 51, a tongue portion 52, a blade portion 53, and a stopper portion 54. , and a mark display portion 55 .

The guide body portion 51 is a portion that guides the carrier tape 80 when the carrier tape 80 is transported in the transport direction X. The guide main body 51 extends along the transport direction X and has a U-shaped cross section. The guide body portion 51 has an upper wall portion 56 and a pair of side wall portions 57 .

The upper wall portion 56 is a portion arranged above the tape transport path 31 and faces the upper surface of the carrier tape 80 transported in the transport direction X. The upper wall portion 56 has a function of restricting upward movement of the carrier tape 80 and preventing the carrier tape 80 from floating. The pair of side wall portions 57 respectively extend downward from the width direction end portions of the upper wall portion 56 and face the side surfaces of the carrier tape 80 that is transported in the transport direction X. As shown in FIG. The side wall portion 57 is arranged on the left side with respect to the transport direction X and has a function of restricting leftward movement of the carrier tape 80 on the tape transport path 31 . The side wall portion 57 is arranged on the right side with respect to the transport direction X and has a function of restricting the rightward movement of the carrier tape 80 on the tape transport path 31 .

The tongue portion 52 is a portion inserted between the base tape 81 and the cover tape 82 while the carrier tape 80 is being conveyed. The blade portion 53 is a portion that partially peels off the cover tape 82 from the base tape 81 and exposes the electronic component 2 in the cavity 83 by being inserted into the bonding portion between the base tape 81 and the cover tape 82 . .

The upper wall portion 56 of the guide main body portion 51 has an opening portion 56a. The opening 56a is formed by cutting out a portion of the upper wall portion 56 . The tongue portion 52 is arranged so as to be exposed to the outside while covering part of the opening portion 56a. The tongue portion 52 is formed in a plate shape so as to extend along the transport direction X. As shown in FIG. The lower surface of the tongue portion 52 is substantially flat without steps. The tongue portion 52 is held such that its plate surface is substantially horizontal or inclined with the tip portion 52a facing downward. The tongue portion 52 is fixed to the guide main body portion 51 by welding or the like at one end, that is, the end portion on the downstream side in the transport direction X, and is cantilevered by the guide main body portion 51 . The tongue portion 52 is arranged with the tip portion 52a directed toward the upstream side in the transport direction X. As shown in FIG.

The tongue portion 52 can be elastically deformed in the vertical direction by applying an external force F from above while being supported by the guide main body portion 51 at one end. Specifically, the tongue portion 52 is normally held such that the plate surface is substantially horizontal from the support point for the guide main body portion 51 . 11 to 13, when an external force F is applied downward by a worker's (operator's) pressure against the portion exposed to the outside through the opening 56a, the tongue portion 52 is formed into the tip portion 52a. bends downward, and when the application of the external force F is released by releasing the pressure, the distal end portion 52a is elastically deformed to return to its original state, as shown in FIG.

The elastic deformation of the tongue portion 52 corresponds to at least the range in which the height of the boundary between the base tape 81 and the cover tape 82 varies depending on the type of the carrier tape 80 and the state of the leading end in the conveying direction X, and the leading end portion 52a becomes the base. The height position of the tip portion 52a (hereinafter referred to as tip height) is moved up and down so that it can be inserted between the tape 81 and the cover tape 82 . The tip height of the tip portion 52a of the tongue portion 52 is normally a reference height, and becomes lower than the reference position as the external force F applied to the upper surface of the tongue portion 52 increases. When the height of the boundary between the base tape 81 and the cover tape 82 of the carrier tape 80 is the lowest height, the tongue portion 52 is elastically deformed according to the lowest height, and the tip portion 52a is the lowest height. It is lowered to a height (hereinafter referred to as the minimum tip height) that matches the height.

The tongue portion 52 has a predetermined length from one end that is cantilevered by the guide main body portion 51 to the tip portion 52a. This predetermined length is set to a length that allows the tip portion 52a of the tongue portion 52 to move downward from the reference height to the minimum tip height. The external force F applied to the tongue portion 52 by the operator to position the tip portion 52a of the tongue portion 52 at the lowest tip height is such that the tip portion 52a of the tongue portion 52 is moved to the lowest tip height by the finger force of the operator. It is sufficient if the force is set so that it can be positioned at a height.

The tongue portion 52 has a predetermined width in the tape width direction of the carrier tape 80 . This predetermined width is set to be smaller than the tape width of the carrier tape 80 . As shown in FIG. 9, the tongue portion 52 is located on one tape width direction end portion side (specifically, feed hole 85 is arranged so as to be biased toward the side opposite to the side on which 85 is provided.

The tongue portion 52 is formed in a mountain shape so that the center portion in the width direction protrudes toward the upstream side in the conveying direction X from the end portions in the width direction, and the tip portion 52a is formed at one end portion in the width direction (specifically, , is formed so as to be biased toward the width direction end where the feed hole 85 is provided. The tongue portion 52 is arranged such that the tip portion 52 a is located directly above the cavity 83 of the base tape 81 . A distal end portion 52a of the tongue portion 52 is formed in a tapered shape such that the lower surface thereof is inclined upward from the downstream side in the conveying direction X to the upstream side in the conveying direction X. As shown in FIG. In order to improve the insertability of the tip portion 52a between the base tape 81 and the cover tape 82, the lower surface of the tip portion 52a is elastically deformed by pressing the tongue portion 52 downward. It may be horizontal when positioned at the lowest tip height of the

The blade portion 53 is inserted between the base tape 81 and the cover tape 82 that are adhered to each other at one tape width direction end of the carrier tape 80 on the upstream side in the transport direction X from the component supply position P, This is a portion where the cover tape 82 is partially peeled off from the base tape 81 to expose the electronic component 2 in the cavity 83 of the base tape 81 . The blade portion 53 is located at one end of the tongue portion 52 in the width direction, specifically, at both ends of the tape width direction where the cover tape 82 is adhered to the base tape 81 of the carrier tape 80 . It is provided so as to correspond to one of the tape width direction end portions (specifically, the side opposite to the side where the feed hole 85 is provided).

The stopper portion 54 is a portion with which the tongue portion 52 abuts when the tongue portion 52 is elastically deformed more than a predetermined amount. The stopper portion 54 restricts the downward movement of the tip portion 52a of the tongue portion 52 after the tip portion 52a abuts thereon. The stopper portion 54 is the upper portion of one of the pair of side wall portions 57 of the guide main body portion 51 (specifically, the right side wall portion 57 with respect to the transport direction X). The stopper portion 54 is provided adjacent to a portion of the upper wall portion 56 where the opening portion 56a is provided.

As described above, the tongue portion 52 of the tape guide 50 is arranged so as to be exposed to the outside through the opening portion 56a. The tongue portion 52 has a facing portion 52b that faces the stopper portion 54 in the vertical direction. The opposing portion 52b is formed integrally with the body portion of the tongue portion 52 so as to protrude from the body portion in the tape width direction. The opposing portion 52b abuts against the stopper portion 54 when the tongue portion 52 is elastically deformed by the application of the external force F, thereby restricting the movement of the tongue portion 52 beyond it.

The stopper portion 54 and the tongue portion 52 are arranged at the tip portion of the tongue portion 52 when the opposing portion 52b of the tongue portion 52 contacts the stopper portion 54 according to the external force application position where the external force F is applied on the upper surface of the tongue portion 52. The tip height of 52a is formed to vary. Specifically, the lower surface of the tongue portion 52 (specifically, the opposing portion 52b) that contacts the stopper portion 54 is formed flat. The upper surface of the stopper portion 54 with which the tongue portion 52 abuts is formed in a stepped shape.

The stopper portion 54 has a stepped portion 54a as shown in FIG. The stepped portion 54a is formed such that the height of the upper surface of the stopper portion 54 decreases stepwise from one end side of the tongue portion 52, that is, from the root side to the tip side. As shown in FIGS. 8 and 11 to 13, the stepped portion 54a is formed so as to have, for example, three substantially horizontal planar portions, namely upper, middle and lower portions. Hereinafter, it is assumed that the stepped portion 54a has three flat portions, and these three flat portions are referred to as an upper step portion 54aH, a middle step portion 54aM, and a lower step portion 54aL in order from the upper step side.

For example, as shown in FIG. 11, when the external force applying position where the external force F is applied is the root side of the tongue portion 52, the opposing portion 52b of the tongue portion 52 contacts the upper step portion 54aH of the stepped portion 54a of the stopper portion 54. It can be flexed and elastically deformed until it touches, and after the opposing portion 52b contacts the upper step portion 54aH, even if the external force F is further increased, it cannot be flexed downward beyond it. When the opposing portion 52b contacts the upper step portion 54aH, the tip height of the tip portion 52a of the tongue portion 52 becomes the upper step height.

Further, as shown in FIG. 12, when the above-mentioned external force applying position is intermediate between the base side and the tip side of the tongue portion 52, the tongue portion 52 is such that the opposing portion 52b is the middle step portion 54aM of the stepped portion 54a of the stopper portion 54. After the opposing portion 52b abuts against the middle step portion 54aM, even if the external force F is further increased, the opposing portion 52b cannot be bent downward beyond it. When the opposing portion 52b abuts on the middle step portion 54aM, the tip height of the tip portion 52a of the tongue portion 52 becomes the middle step height.

Further, as shown in FIG. 13, when the above external force applying position is the distal end side of the tongue portion 52, the tongue portion 52 is bent until the opposing portion 52b comes into contact with the lower step portion 54aL of the stepped portion 54a of the stopper portion 54. It can be elastically deformed, and after the opposing portion 52b abuts against the lower step portion 54aL, even if the external force F further increases, it cannot be bent downward beyond it. When the opposing portion 52b abuts on the lower portion 54aL, the tip height of the tip portion 52a of the tongue portion 52 becomes the lower step height.

The mark display portion 55 indicates the correspondence relationship between the external force application position where the external force F is applied and the tip height reached by the tip portion 52a of the tongue portion 52 when the tongue portion 52 comes into contact with the stopper portion 54 due to the application of the external force F.

2. Operation of Component Feeding Device and Tape Guide In the component feeding device 1, the tape guide 50, as shown in FIG. The tip height of the tip portion 52a is at the reference height.

Before the tip of the carrier tape 80 inserted into the tape entrance of the component supply device 1 in the transport direction X reaches the tongue portion 52 of the tape guide 50, the operator moves the tongue portion 52 from above through the opening portion 56a of the tape guide 50 from below. Then, the tip height of the tip portion 52a of the tongue portion 52 is shifted to a position lower than the reference height.

Specifically, the operator operates the manual handle 36 to rotate the manual sprocket 35, thereby conveying the carrier tape 80 inserted into the tape inlet of the component supply device 1 in the conveying direction X, and opening the opening. The position of the boundary between the base tape 81 and the cover tape 82 and the state of the cover tape 82 relative to the base tape 81 are checked by visually checking the forward end of the carrier tape 80 that has reached the portion 56a. Then, the operator selects the external force application position to which the external force F is to be applied from among the mark display portions 55 on the upper surface of the tongue portion 52 in accordance with the boundary height position and the like. An external force F is applied to make the tip height of the tip portion 52a lower than the reference height.

The external force F is applied until the opposing portion 52b of the tongue portion 52 contacts the stopper portion 54, and the tongue portion 52 is applied between the base tape 81 and the cover tape 82 at the tip of the carrier tape 80 in the transport direction X. The contact state is maintained until the timing when the distal end portion 52a is inserted.

For example, when it is confirmed that the boundary height position is relatively high, the position of the "H" mark display portion 55 is selected as the external force applying position, and the external force F is applied to that position, The portion 52 contacts the upper step portion 54 aH of the stopper portion 54 . Further, when it is confirmed that the boundary height position is relatively low, the position of the mark display portion 55 of "L" is selected as the external force application position, and the external force F is applied to that position. The portion 52 abuts on the lower portion 54aL of the stopper portion 54. As shown in FIG. When the tongue portion 52 is in contact with the stopper portion 54, even if the external force F is further increased, further downward movement of the tongue portion 52 is restricted.

When the manual sprocket 35 is further rotated while the tongue portion 52 is in contact with the stopper portion 54 by applying the external force F, and the carrier tape 80 is conveyed in the conveying direction X, the base tape at the tip of the carrier tape 80 in the conveying direction X A tip portion 52 a of the tongue portion 52 is inserted between 81 and the cover tape 82 . Therefore, even when the boundary height position between the base tape 81 and the cover tape 82 or the state of the cover tape 82 with respect to the base tape 81 changes, the distal end portion 52a of the tongue portion 52 is adjusted to the boundary height position or the like. By changing the tip height of the carrier tape 80, the tip portion 52a of the tongue portion 52 can be appropriately inserted between the base tape 81 and the cover tape 82 at the tip of the carrier tape 80 in the X direction.

After the tip 52a of the tongue 52 of the tape guide 50 is inserted between the base tape 81 and the cover tape 82 at the tip of the carrier tape 80 in the X direction, the operator applies an external force downward on the tongue 52. Release the F grant. When the application of the external force F is released, the tongue portion 52 is elastically deformed downward and is deformed back to its original substantially horizontal state, and the tip height of the tip portion 52a returns to the reference height.

With the tip height of the tip portion 52a of the tongue portion 52 returning to the reference height by releasing the application of the external force F as described above, the carrier tape 80 is moved in the conveying direction X by rotating the manual sprocket 35 or the automatic sprocket 37. When conveyed, the tongue portion 52 is kept inserted between the base tape 81 and the cover tape 82, and the blade portion 53 is positioned at one end in the width direction of the tape where the base tape 81 and the cover tape 82 are adhered. It is inserted into the adhesive part at the part. Therefore, when the tip height of the tip portion 52a of the tongue portion 52 returns to the reference height, the blade portion 53 is used to separate the cover tape 82 from the base tape 81, so that the inside of the cavity 83 of the base tape 81 is Electronic component 2 can be exposed.

As described above, in the tape guide 50 , the stopper portion 54 and the tongue portion 52 are arranged such that the opposite portion 52 b of the tongue portion 52 is attached to the stopper portion 54 in accordance with the external force applying position on the upper surface of the tongue portion 52 to which the external force F is applied. The tip height of the tip portion 52a of the tongue portion 52 at the time of contact is formed to vary. Specifically, the lower surface of the tongue portion 52 (specifically, the opposing portion 52b) that contacts the stopper portion 54 is formed flat, and the upper surface of the stopper portion 54 that the tongue portion 52 contacts is It is formed stepwise. That is, the stopper portion 54 has a stepped portion 54a formed so that the height of the upper surface of the stopper portion 54 decreases stepwise from one end side of the tongue portion 52, that is, from the root side to the tip side.

In such a configuration, the position where the external force F is applied on the upper surface of the tongue portion 52 changes in the extending direction of the tongue portion 52, so that the tip of the tongue portion 52 when the tongue portion 52 abuts against the stopper portion 54 is changed. The tip height of the portion 52a can be changed up and down. For this reason, unlike the structure in which the tip height of the tip portion 52a of the tongue portion 52 when the tongue portion 52 abuts against the stopper portion 54 is limited to one, the tongue portion 52 can be adapted to various carrier tapes 80. Since the tip height of the tip portion 52 a can be changed, the tip portion 52 a can be appropriately inserted between the base tape 81 and the cover tape 82 .

Further, the above-described variable tip height of the tip portion 52a of the tongue portion 52 is not realized by changing the magnitude of the external force F applied to the upper surface of the tongue portion 52. This is realized by changing the contact position of the step portion 54a of the stopper portion 54 against which the tongue portion 52 abuts due to the application of the external force F while changing the position where the external force F is applied in the extending direction of the tongue portion 52.

Therefore, the tip height of the tip portion 52a of the tongue portion 52 can be changed regardless of the magnitude of the external force F that pushes down the tongue portion 52 and elastically deforms it. can be maintained and fixed. Therefore, according to the tape guide 50, the tip portion 52a of the tongue portion 52 can be accurately and appropriately inserted between the base tape 81 and the cover tape 82 corresponding to various carrier tapes 80. FIG.

Further, the tip portion 52a of the tongue portion 52 of the tape guide 50 is positioned at a tip height lower than the reference height just before the carrier tape 80 is inserted between the base tape 81 and the cover tape 82, After that, it is returned to the reference height. In such a configuration, the tip height of the tip portion 52a of the tongue portion 52 is maintained lower than the reference height even after the carrier tape 80 is inserted between the base tape 81 and the cover tape 82. , after the tip 52a of the tongue 52 is inserted between the base tape 81 and the cover tape 82 of the carrier tape 80, the tip 52a of the tongue 52 and the electronic component 2 in the cavity 83 of the base tape 81 move up and down. The difference in altitude between directions can be increased. Therefore, it is possible to prevent the electronic component 2 from contacting the corners of the distal end portion 52 a of the tongue portion 52 .

Therefore, according to the tape guide 50, the tongue portion 52 is appropriately inserted between the base tape 81 and the cover tape 82 at the tip of the carrier tape 80 in the transport direction X, and the tip portion 52a of the tongue portion 52 after the insertion. Contact of the electronic component 2 in the cavity 83 of the base tape 81 can be suppressed. For this reason, the tip portion 52a of the tongue portion 52 is inserted between the base tape 81 and the cover tape 82 at the leading end of the carrier tape 80 in the X direction, and the blade portion 53 separates the cover tape 82 from the base tape 81 to remove the base tape. After exposing the electronic component 2 in the cavity 83 of the tape 81 , the electronic component 2 can be prevented from being damaged due to contact with the tongue portion 52 .

Also, the stopper portion 54 is the upper portion of the side wall portion 57 of the guide body portion 51 . Therefore, a structure for restricting the positional movement of the tongue portion 52 can be easily realized without preparing a component other than the guide main body portion 51 .

Further, on the upper surface of the tongue portion 52, there is an external force application position where the external force F is applied by the operator and a tip height reached by the tip portion 52a when the tongue portion 52 contacts the stopper portion 54 due to the application of the external force F. A mark display portion 55 indicating the correspondence is provided. Therefore, the stopper portion 54 with which the tongue portion 52 abuts is formed in a stepped shape, and the tip height of the tip portion 52a of the tongue portion 52 at the time of contact with the stopper portion 54 can be varied up and down. can be indirectly notified, and an index indicating where on the upper surface of the tongue portion 52 should be pushed down in order to shift the tip height of the tip portion 52a of the tongue portion 52 from the reference height to the desired height position can be conveyed in an easy-to-understand manner. Therefore, it is convenient for an operator to apply an external force F to the upper surface of the tongue portion 52 in order to elastically deform the tongue portion 52 of the tape guide 50 and insert it between the base tape 81 and the cover tape 82 of the carrier tape 80 . can improve sexuality.

3. Modifications By the way, in the above embodiment, the cover tape 82 is adhered to the base tape 81 and the electronic component 2 in the cavity 83 is covered with the cover tape 82. The electronic component 2 is exposed by inserting it into the adhesive portion between the tape 81 and the cover tape 82 and partially peeling off the cover tape 82 from the base tape 81 .

However, the present disclosure is not limited to this, and in order to expose the electronic component 2 in the cavity 83, the cover tape 82 is opened without peeling off the cover tape 82 from the base tape 81 at the adhesive portion. It may be applied to For example, instead of peeling the cover tape 82 from the base tape 81 by the blade 53 provided on the tongue 52, the cover tape 82 is split in the tape width direction using a cutter whose blade is directed vertically. may be used to expose the electronic component 2 in the cavity 83 .

Further, in the above embodiment, the upper surface of the stopper portion 54 with which the tongue portion 52 abuts is formed in a stepped shape, and the stopper portion 54 has the stepped portion 54a consisting of three plane portions. However, the present disclosure is not limited to this, and the stopper portion 54 may have a stepped portion 54a consisting of two or four or more planar portions.

It is good also as forming in a stepped shape. In this modified form, the tongue portion 52 has a stepped portion 52c formed so that the height of the lower surface increases stepwise from the base side to the tip side of the tongue portion 52 . As shown in FIG. 14, the step portion 52c is formed such that there are, for example, three substantially horizontal plane portions, upper, middle and lower. These three plane portions are an upper step portion 52cH, a middle step portion 52cM, and a lower step portion 52cL in order from the upper step side. The stepped portion 52c may be formed at the facing portion 52b where the tongue portion 52 abuts against the stopper portion 54. As shown in FIG.

In the modified form described above, when the external force applying position where the external force F is applied is on the root side of the tongue portion 52, the tongue portion 52 bends and elastically deforms until the lower step portion 52cL contacts the stopper portion 54. After the contact, even if the external force F is further increased, it cannot be bent downward beyond it. In this contact state, the tip height of the tip portion 52a of the tongue portion 52 is the upper step height. Further, when the external force applying position is intermediate between the base side and the tip side of the tongue portion 52, the tongue portion 52 can bend and elastically deform until the middle step portion 52cM contacts the stopper portion 54. After the abutment, even if the external force F is further increased, it cannot be bent downward beyond it. In this contact state, the tip height of the tip portion 52a of the tongue portion 52 is the middle height. Further, when the external force application position is the distal end side of the tongue portion 52, the tongue portion 52 can bend and elastically deform until the upper step portion 52cH abuts against the stopper portion 54, after which the external force is applied. Even if F is further increased, it cannot be deflected downward beyond it. In this contact state, the tip height of the tip portion 52a of the tongue portion 52 is the lower step height.

Also in the above-described modified form, the position of the external force F applied to the upper surface of the tongue portion 52 is changed in the extending direction of the tongue portion 52, so that the tongue portion 52 when the tongue portion 52 abuts against the stopper portion 54 The tip height of the tip portion 52a can be changed up and down, thereby obtaining the same effect as the above embodiment.

As shown in FIG. The clamp guide portion 57a is formed to be inclined or curved so that the position of the tongue portion 52 decreases from the root side to the tip side.

The clamp portion 58 is held so as to be slidable in the extending direction of the tongue portion 52 . A lower wall portion 58b of the clamp portion 58 is supported below the clamp guide portion 57a along the clamp guide portion 57a. The upper wall portion 58c of the clamp portion 58 is supported above the tongue portion 52 along the upper surface of the tongue portion 52 . The clamp portion 58 presses the tongue portion 52 against the stopper portion 54 between the lower wall portion 58b and the upper wall portion 58c to generate an external force F that clamps the tongue portion 52 and the stopper portion 54 .

When the holding position where the clamp portion 58 is held in the extending direction of the tongue portion 52 changes, the external force application position where the external force F is applied to the upper surface of the tongue portion 52 by the clamp portion 58 changes, and the tongue portion 52 hits. The position of the stepped portion 54a of the contacting stopper portion 54 changes, and the tip height of the tip portion 52a of the tongue portion 52 when the tongue portion 52 contacts the stopper portion 54 changes. Therefore, even in this modified form, the same effect as the above modified form can be obtained.

In the modified form described above, the stopper portion 54 and the tongue portion 52 are arranged so that the tongue portion 52 contacts the stopper portion 54 depending on the external force application position on the upper surface of the tongue portion 52 where the external force F is applied. The tip height of the tip portion 52a of the portion 52 is formed to vary. Specifically, the stopper portion 54 has a stepped portion 54a, and the tongue portion 52 is pressed against the stepped portion 54a of the stopper portion 54 using the clamp portion 58. The position of the step portion 54a of the stopper portion 54 with which the tongue portion 52 abuts is changed by changing the holding position.

In the modified form described above, the clamp portion 90 is formed to have a U-shaped cross section, and includes a side wall portion 90a, a lower wall portion 90b extending from the lower end of the side wall portion 90a, and a lower wall portion extending from the upper end of the side wall portion 90a. and an upper wall portion 90c facing the portion 90b. The clamp portion 90 is configured so that the lower wall portion 90b and the upper wall portion 90c do not elastically deform, that is, the distance between the two

wall portions

90b and 90c does not change.

The guide main body portion 51 of the tape guide 50 has a clamp guide portion 57b that holds the clamp portion 58 slidably in the extending direction of the tongue portion 52 .

Further, the upper wall portion 90c of the clamp portion 90 is supported on the upper side of the tongue portion 52 along the upper surface of the tongue portion 52 . The distance between the lower wall portion 90b and the upper wall portion 90c of the clamp portion 90 is made smaller than the distance between the upper surface of the tongue portion 52 and the lower surface of the clamp guide portion 57b in the normal state where elastic deformation does not occur. is set to The clamp portion 90 applies an external force F elastically deforming the tongue portion 52 to the upper surface of the tongue portion 52 with the upper wall portion 90c while being supported by the clamp guide portion 57b with the lower wall portion 90b. The external force F applied to the tongue portion 52 by the clamp portion 90 is a reaction force accompanying elastic deformation of the tongue portion 52 .

When the holding position where the clamp portion 90 is held in the extending direction of the tongue portion 52 changes, the external force application position where the external force F is applied to the upper surface of the tongue portion 52 by the clamp portion 90 changes, and the tip of the tongue portion 52 changes. The tip height of the portion 52a changes. Specifically, the tip height of the tip portion 52a of the tongue portion 52 becomes lower as the external force application position is closer to the tip side of the tongue portion 52 .
