Description

This specification relates to a tape guide and a component supply device.

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

The above-mentioned tape guide has a guide body that guides the carrier tape when the carrier tape is transported in the transport direction, and a tongue that is inserted between the base tape and the cover tape to expose the electronic components in the cavity. The tongue is fixed to the guide body by welding or the like and extends in the counter-transport direction opposite to the transport direction. The tongue is positioned so that its tip 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. When the tongue is inserted between the base tape and the cover tape, the blade then cuts and divides the cover tape, exposing the electronic components in the cavity.

JP 2016-26415 A

In the tape guide described in the above-mentioned Patent Document 1, as described above, the tongue portion is fixed to the guide body portion, and the tip portion of the tongue portion is fixed at a height position where it is inserted between the base tape and the cover tape of the carrier tape (hereinafter referred to as the insertion height position). Therefore, even after the tip portion of the carrier tape in the transport direction reaches the tip portion of the tongue portion during transport of the carrier tape and the tip portion of the tongue portion is inserted between the base tape and the cover tape, the lower surface of the tip portion of the tongue portion remains in contact with the upper surface of the base tape, so that the electronic components in the cavity of the base tape are likely to come into contact with the corner of the tip portion of the tongue portion.

On the other hand, in order to make it difficult for the corner of the tip of the tongue to come into contact with the electronic components in the cavity of the base tape, a structure in which the tip of the tongue is fixed at a position higher than the above-mentioned insertion height position can be considered. However, with this structure, it becomes difficult to insert the tip of the tongue between the base tape and the cover tape at the leading end of the carrier tape in the transport direction, which may make it difficult to properly expose the electronic components in the cavity of the base tape.

In order to avoid the above-mentioned inconvenience, it is conceivable to provide 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, if the tip of the tongue is moved from the high position to the low position and inserted between the base tape and the cover tape at the leading end of the carrier tape in the transport direction, and the tip of the tongue is moved from the low position to the high position after the insertion to transport the carrier tape, the tip of the tongue can be appropriately inserted between the base tape and the cover tape while preventing the tip of the tongue from contacting the electronic components in the cavity of the base tape after the insertion.

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

However, depending on the type of carrier tape and the state of the leading edge in the transport direction, the height of the boundary between the base tape and the cover tape at the leading edge in the transport direction of the carrier tape during transport is not limited to a fixed height and may fluctuate up and down. For this reason, a structure in which the low position of the leading edge of the tongue when the tongue abuts on the stopper is limited to one height position cannot accommodate various carrier tapes, lacks versatility, and reduces workability. On the other hand, if the magnitude of the force pressing down on the tongue from above is changed, it is possible to adjust the low position of the leading edge of the tongue when the tongue abuts on the stopper without limiting it to one, but it becomes impossible to stably fix the leading edge of the tongue at a low position.

The purpose of this specification is to provide a tape guide and component supply device that can appropriately insert the tip of the tongue between the base tape and the cover tape to accommodate various carrier tapes by changing the tip height of the tongue regardless of the magnitude of the force pressing down on the tongue from above.

This specification discloses a tape guide comprising: a guide body portion that guides a carrier tape having a base tape 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 when the carrier tape is transported in a transport direction; a tongue portion that is cantilevered on the guide body portion so as to be elastically deformable when an external force is applied from above 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 against which the tongue portion abuts when the tongue portion elastically deforms by a predetermined amount or more, wherein the stopper portion and the tongue portion are formed such that the tip height of the tongue portion when it abuts against the stopper portion changes depending on the external force application position on the upper surface of the tongue portion where the external force is applied.

According to the present disclosure, the tip height of the tongue when it abuts against the stopper portion can be changed according to the position of the external force on the upper surface of the tongue. Therefore, by changing the tip height of the tongue regardless of the magnitude of the force pressing down on the tongue from above, the tip of the tongue can be appropriately inserted between the base tape and the cover tape in accordance with various carrier tapes.

This specification discloses a tape guide comprising: a guide body portion that guides a carrier tape having a base tape 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 when the carrier tape is transported in a transport direction; a tongue portion that is cantilevered on the guide body portion so as to be elastically deformable when an external force is applied from above and is inserted between the base tape and the cover tape during transport of the carrier tape; and a clamp portion that is slidably held in the extension direction of the tongue portion and applies an external force to the upper surface of the tongue portion from above to elastically deform the tongue portion, wherein the tip height of the tongue portion changes depending on the external force application position on the upper surface of the tongue portion where the external force is applied.

According to the present disclosure, the tip height of the tongue portion can be changed depending on the position on the upper surface of the tongue portion where an external force is applied. Therefore, by changing the tip height of the tip of the tongue portion regardless of the magnitude of the force pressing down on the tongue portion from above, the tip of the tongue portion can be appropriately inserted between the base tape and the cover tape in accordance with various carrier tapes.

1. Configuration of a component supplying device including a tape guide The configuration of a component supplying device 1 according to an embodiment will be described.
The component supplying device 1 is a tape feeder that supplies electronic components to a component supplying position P by transporting a carrier tape having electronic components stored in cavities in a transport direction X. The component supplying device 1 is incorporated in a component mounting machine that is provided on a board production line and mounts electronic components on boards. Hereinafter, the component supplying device 1 is assumed to be a cassette type tape feeder as shown in FIG.

The carrier tape 80 is a tape member formed in a long shape for supplying the electronic components 2 to a component supply device. The carrier tape 80 has a predetermined width dimension (i.e., tape width). In general, the tape width of the carrier tape 80 varies depending on the type of carrier tape 80 or the size of the electronic components 2 to be stored. This tape width is determined as a standard in advance, and is, for example, 4 mm, 8 mm, 12 mm, 16 mm, 24 mm wide, etc. The electronic components 2 are components such as transistors, diodes, and resistors that constitute electronic circuits. The electronic components 2 may include, for example, microcomponents such as 0201 size (0.2 mm x 0.1 mm).

2 and 3, the carrier tape 80 has a base tape 81 and a cover tape 82. The base tape 81 is a tape provided with a cavity 83 for housing an electronic component 2. The cover tape 82 is a tape provided on the surface (upper surface) of the base tape 81 so as to close the cavity 83.

The base tape 81 is made of a flexible material such as paper or resin. The base tape 81 has a cavity 83. The cavity 83 is a storage space such as a hole or groove that stores the electronic component 2. The carrier tape 80 may be an embossed tape in which the cavity 83 of the base tape 81 protrudes downward, or may be a paper tape with a groove-shaped cavity 83 provided on the surface.

The cavity 83 is provided at approximately the center of the base tape 81 in the tape width direction. A plurality of cavities 83 are provided along the tape longitudinal direction, and are arranged in a row at a predetermined interval. When the cavity 83 is a hole penetrating the base tape 81 as shown in FIG. 3, a bottom tape 84 that covers the bottom of the cavity 83 is further adhered to the lower surface of the base tape 81 to prevent the electronic component 2 from falling out. This bottom tape 84 may be made of a transparent or translucent paper material, a polymer film, or the like.

The base tape 81 also has a feed hole 85. The feed hole 85 is a through hole provided to transport the carrier tape 80 in the tape longitudinal direction, i.e., the transport direction X. The feed hole 85 is an engagement hole that engages with an engagement protrusion of a sprocket, which is described later, of the component supply device 1. The feed hole 85 is formed in a substantially circular or elliptical shape. The feed hole 85 is provided at one end of the base tape 81 in the tape width direction. A plurality of feed holes 85 are provided along the tape longitudinal direction, and are arranged in a row at a predetermined interval. The cavities 83 and the feed holes 85 are arranged in two rows in the tape width direction, each along the tape longitudinal direction.

The cover tape 82 is removably adhered to the surface of the base tape 81. The cover tape 82 is adhered to both ends of the surface of the base tape 81 in the width direction of the tape, excluding the central portion in the width direction of the tape where the cavity 83 is provided. The cover tape 82 covers and closes the opening of the cavity 83 by being adhered and fixed to the base tape 81. The cover tape 82 has the function of preventing the electronic component 2 housed in the cavity 83 from popping out 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 that of the base tape 81, or may be adhered to the base tape 81 except for the portion where the feed holes 85 are provided, as shown in FIG. 3, and may have a tape width smaller than that of the base tape 81. The tape width of the cover tape 82 may differ depending on the type of carrier tape 80, i.e., the tape width of the base tape 81.

As shown in Figures 1 and 4, the part supply device 1 comprises a cassette case 10, a tape loading section 20, a conveying device 30, a part exposure device 40, and a tape discharge section 60.

The cassette case 10 is a case member in which a space is formed capable of accommodating a tape reel 89 around which a carrier tape 80 is wound. The cassette case 10 is formed in a thin rectangular shape from a transparent or opaque plastic plate or metal plate. The cassette case 10 has a cover 11 that opens and closes to expose the above-mentioned space. The cover 11 is provided, for example, on the side of the cassette case 10.

The tape loading section 20 is a section in which the tape reel 89 is removably loaded. The tape loading section 20 is provided inside the cassette case 10. The tape loading section 20 has a support shaft that rotatably supports the tape reel 89 inside the cassette case 10. The tape reel 89 is attached to and detached from the tape loading section 20 when the cover 11 of the cassette case 10 is open, and rotates while supported by the support shaft to pull out the carrier tape 80 and transport it in the transport direction X.

The conveying device 30 is a device that conveys the carrier tape 80 pulled out from the tape reel 89 loaded in the tape loading section 20 in the conveying direction X. As shown in Figures 1 and 4, the conveying device 30 has a tape conveying path 31, a backup leaf spring 32, and a support leaf spring 33.

The tape transport path 31 is a transport path that transports 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 extends linearly from the pull-out outlet of the carrier tape 80 in the tape reel 89 toward the component supply position P. The tape transport path 31 abuts against the underside of the carrier tape 80 to support the underside. The tape transport path 31 is formed to have an inclined portion that gradually becomes higher from the upstream side to the downstream side of the transport 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 underside of the carrier tape 80 (specifically, the base tape 81) on the tape transport path 31. The backup leaf spring 32 generates a biasing force that biases the carrier tape 80 on the tape transport path 31 upward and presses the upper surface of the carrier tape 80 against the tape guide 50 described below. The backup leaf spring 32 is provided in the cassette case 10 and is disposed downstream of the tape transport path 31 in the transport direction X. The backup leaf spring 32 extends in the transport direction X along the tape transport path 31, and is supported at one end by the cassette case 10 in a manner that allows it to elastically deform.

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 on the tape transport path 31 when the carrier tape 80 on the tape transport path 31 is an embossed tape. The support leaf 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 lowering due to its own weight. The support leaf spring 33 is provided inside the cassette case 10 and is disposed downstream of the tape transport path 31 in the transport direction X.

The tape transport path 31 has a groove into which the downwardly protruding cavity 83 in the embossed carrier tape 80 can engage. This groove is formed to a size corresponding to the embossed carrier tape 80 in which the cavity 83 is at its maximum. The support leaf spring 33 is disposed below the groove. One or more support leaf springs 33 are provided (three in FIG. 4). Each support leaf spring 33 extends in the transport direction X along the tape transport path 31, and one end is supported by the cassette case 10 so as to be elastically deformable.

The component exposure device 40 is a device that peels off the cover tape 82 from the base tape 81 of the carrier tape 80 that is being transported in the transport direction X along the tape transport path 31, to expose the electronic components 2 in the cavities 83 of the base tape 81. The component exposure device 40 includes a tape guide 50.

The tape guide 50 is a member that guides the carrier tape 80 transported on the tape transport path 31. The tape guide 50 is disposed downstream of 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 that it can swing up and down. The tape guide 50 can hold down the upper surface of the carrier tape 80 on the tape transport path 31. In particular, the tape guide 50 is biased downward and pressed against the cassette case 10, and by holding down the upper surface of the carrier tape 80 even if the tape thickness of the carrier tape 80 changes, it is possible to prevent the carrier tape 80 from floating up and reliably engage the feed hole 85 with the sprocket.

The tape guide 50 can insert a tongue portion 52 (described later) between the base tape 81 and cover tape 82 of the carrier tape 80 while pressing the top surface of the carrier tape 80 on the tape transport path 31, and can peel 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 Figures 4, 5, 6, 7, 8, 9, and 10, the tape guide 50 has a guide body portion 51, a tongue portion 52, a blade portion 53, a stopper portion 54, and a mark display portion 55.

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

The upper wall portion 56 is a portion disposed 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 the upward movement of the carrier tape 80 to prevent the carrier tape 80 from floating up. The pair of side wall portions 57 are portions extending downward from the widthwise ends of the upper wall portion 56 and face the side surfaces of the carrier tape 80 transported in the transport direction X. The side wall portion 57 is disposed on the left side with respect to the transport direction X and has a function of restricting the movement of the carrier tape 80 to the left on the tape transport path 31. The side wall portion 57 is disposed on the right side with respect to the transport direction X and has a function of restricting the movement of the carrier tape 80 to the right on the tape transport path 31.

The tongue portion 52 is a portion that is inserted between the base tape 81 and the cover tape 82 while the carrier tape 80 is being transported. The blade portion 53 is a portion that is inserted into the adhesion portion between the base tape 81 and the cover tape 82, thereby partially peeling the cover tape 82 from the base tape 81 to expose the electronic component 2 in the cavity 83.

The upper wall 56 of the guide body 51 has an opening 56a. The opening 56a is formed by cutting out a part of the upper wall 56. The tongue 52 is arranged to be exposed to the outside while blocking a part of the opening 56a. The tongue 52 is formed in a plate shape so as to extend along the conveying direction X. The lower surface of the tongue 52 is substantially flat without any steps. The tongue 52 is held so that its plate surface is substantially horizontal or inclined with the tip 52a facing downward. The tongue 52 is fixed to the guide body 51 by welding or the like at one end, i.e., the end on the downstream side of the conveying direction X, and is supported by the guide body 51 in a cantilever manner. The tongue 52 is arranged with the tip 52a facing the upstream side of the conveying direction X.

With one end of the tongue portion 52 supported by the guide body portion 51, the tongue portion 52 can be elastically deformed in the vertical direction by the application of an external force F from above. Specifically, the tongue portion 52 is held so that the plate surface is generally horizontal from the support point for the guide body portion 51 in the normal state. When an external force F is applied downward by the worker (operator) pressing the portion of the tongue portion 52 exposed to the outside through the opening 56a, the tip portion 52a bends downward as shown in Figures 11 to 13, and when the application of the external force F is released by releasing the pressing force, the tip portion 52a elastically deforms to return to its original state as shown in Figure 8.

The elastic deformation of the tongue portion 52 is performed at least in a range in which the height position of the tip portion 52a (hereinafter referred to as the tip height) moves up and down so that the tip portion 52a is inserted between the base tape 81 and the cover tape 82, corresponding to 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 carrier tape 80 and the state of the tip in the transport direction X. The tip height of the tip portion 52a of the tongue portion 52 is a reference height in the normal state, and the greater the external force F applied to the upper surface of the tongue portion 52, the lower the tip height becomes from the reference position. When the height of the boundary between the base tape 81 and the cover tape 82 of the carrier tape 80 is the minimum height, the tongue portion 52 is elastically deformed to match the minimum height, and the tip portion 52a is moved down to a height (hereinafter referred to as the minimum tip height) that matches the minimum height.

The tongue portion 52 has a predetermined length from one end supported by the guide body portion 51 in a cantilever manner 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 that the worker applies to the tongue portion 52 to position the tip portion 52a of the tongue portion 52 at the minimum tip height may be set to a force that allows the tip portion 52a of the tongue portion 52 to be positioned at the minimum tip height with the force of the worker's fingers.

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 arranged so as to be biased toward one of the tape width direction end sides (specifically, the side opposite the side where the feed hole 85 is provided) of both ends in the tape width direction where the cover tape 82 is adhered to the base tape 81 in the carrier tape 80.

The tongue portion 52 is formed in a mountain shape so that the widthwise center protrudes toward the upstream side in the conveying direction X from the widthwise ends, and the tip portion 52a is formed so that it is biased toward one widthwise end (specifically, the widthwise end where the feed hole 85 is provided). The tongue portion 52 is arranged so that the tip portion 52a is located directly above the cavity 83 of the base tape 81. The tip portion 52a of the tongue portion 52 is formed in a tapered shape so that its lower surface is inclined upward from the downstream side in the conveying direction X to the upstream side in the conveying direction X. In addition, the lower surface of the tip portion 52a may be horizontal when the tongue portion 52 is pressed downward and elastically deformed so that the tip portion 52a is positioned at the above-mentioned minimum tip height in order to improve the insertability of the tip portion 52a between the base tape 81 and the cover tape 82.

The blade portion 53 is inserted between the base tape 81 and the cover tape 82, which are bonded to each other at one end of the carrier tape 80 in the conveying direction X, upstream of the component supply position P, and partially peels the cover tape 82 from the base tape 81 to expose the electronic components 2 in the cavities 83 of the base tape 81. The blade portion 53 is provided at a location on the axial tip of the tongue portion 52 that is biased in the width direction, specifically, at one of the end portions in the tape width direction where the cover tape 82 is bonded to the base tape 81 of the carrier tape 80 (specifically, the side opposite to the side where the feed hole 85 is provided).

The stopper portion 54 is a portion against which the tongue portion 52 abuts when the tongue portion 52 elastically deforms to a predetermined degree or more. The stopper portion 54 restricts the tip portion 52 a of the tongue portion 52 from moving downward after the tip portion 52 abuts the stopper portion 54. The stopper portion 54 is an upper portion of one of the pair of side wall portions 57 of the guide body portion 51 (specifically, the right side in the conveying direction X). The stopper portion 54 is provided adjacent to the location where the opening 56 a of the upper wall portion 56 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 56a. The tongue portion 52 has an opposing portion 52b that faces the stopper portion 54 in the up-down direction. The opposing portion 52b is integrally formed with the main body portion of the tongue portion 52 so as to protrude from the main body portion in the tape width direction. When the tongue portion 52 is elastically deformed by the application of an external force F, the opposing portion 52b abuts against the stopper portion 54, thereby restricting the tongue portion 52 from moving beyond it.

The stopper portion 54 and the tongue portion 52 are formed so that the tip height of the tip portion 52a of the tongue portion 52 when the opposing portion 52b of the tongue portion 52 abuts against the stopper portion 54 changes depending on the position at which the external force F is applied on the upper surface of the tongue portion 52. Specifically, the lower surface of the tongue portion 52 (specifically, the opposing portion 52b) that abuts against the stopper portion 54 is formed flat. The upper surface of the stopper portion 54 that abuts against the tongue portion 52 is formed stepped.

As shown in Figure 8, the stopper portion 54 has a stepped portion 54a. The stepped portion 54a is formed so that the height of the top surface of the stopper portion 54 decreases in stages from one end side of the tongue portion 52, i.e., from the base side to the tip side. The stepped portion 54a is formed so that three substantially horizontal flat portions, for example an upper, middle and lower portion, are provided, as shown in Figures 8 and 11 to 13. Hereinafter, the stepped portion 54a is considered to have three flat portions, and these three flat portions are referred to as the upper step portion 54aH, the middle step portion 54aM and the lower step portion 54aL, in order from the top step.

11, when the external force F is applied to the base side of the tongue 52, the tongue 52 can bend and elastically deform until the opposing portion 52b abuts against the upper step 54aH of the stepped portion 54a of the stopper portion 54, and after the opposing portion 52b abuts against the upper step 54aH, it cannot bend downward beyond that point even if the external force F becomes even larger. When the opposing portion 52b abuts against the upper step 54aH, the tip height of the tip 52a of the tongue 52 becomes the upper step height.

12, when the position where the external force is applied is midway between the base side and the tip side of the tongue portion 52, the tongue portion 52 can bend and elastically deform until the opposing portion 52b abuts against the middle step 54aM of the stepped portion 54a of the stopper portion 54, and after the opposing portion 52b abuts against the middle step 54aM, it cannot bend downward beyond that point even if the external force F becomes even larger. When the opposing portion 52b abuts against the middle step 54aM, the tip height of the tip portion 52a of the tongue portion 52 becomes the middle step height.

13, when the position where the external force is applied is the tip side of the tongue portion 52, the tongue portion 52 can bend and elastically deform until the opposing portion 52b abuts against the lower step 54aL of the stepped portion 54a of the stopper portion 54, and after the opposing portion 52b abuts against the lower step 54aL, it cannot bend downward beyond that even if the external force F becomes larger. When the opposing portion 52b abuts against the lower step 54aL, the tip height of the tip portion 52a of the tongue portion 52 becomes the lower step height.

The mark display portion 55 is a mark that indicates the correspondence between the external force application position where the external force F is applied and the tip height that the tip portion 52a of the tongue portion 52 reaches when the tongue portion 52 abuts against the stopper portion 54 due to the application of the external force F. The mark display portion 55 is attached to the upper surface of the tongue portion 52 so as to be visible to the worker. The mark display portion 55 may be a sticker type that is adhered to the upper surface of the tongue portion 52, or may be engraved on the upper surface of the tongue portion 52.

7 and 9, the mark display portion 55 may be marked with "H" indicating that the tip height of the tongue portion 52 is the upper step height, "M" indicating that the tip height is the middle step height, or "L" indicating that the tip height is the lower step height when an external force F is applied to the display position of the mark display portion 55 and the tongue portion 52 abuts against the stopper portion 54. In this case, "H" is marked at the external force application position on the root side of the upper surface of the tongue portion 52, "M" is marked at the external force application position intermediate between the root side and the tip side of the upper surface of the tongue portion 52, and "L" is marked at the external force application position on the tip side of the upper surface of the tongue portion 52. The mark display portion 55 may be marked with a linear scale or a figure according to the possible height of the tip height of the tongue portion 52.

The tape guide 50 also includes a folded portion 59. The folded portion 59 is a portion where one end of the cover tape 82 in the tape width direction on the peeled side of the cover tape 82 is raised and folded back after the blade portion 53 of the tongue portion 52 peels the cover tape 82 from the base tape 81. The folded portion 59 is disposed downstream in the conveying direction X from the blade portion 53 and upstream in the conveying direction X from the component supply position P. The folded portion 59 is formed in a plate shape and is disposed so as to close a part of the opening 56a. The folded portion 59 is formed so that the upstream side in the conveying direction X is pointed and the width increases from the upstream side in the conveying direction X to the downstream side in the conveying direction X.

As shown in FIG. 1, the conveying device 30 also has a manual sprocket 35, a manual handle 36, an automatic sprocket 37, and a motor (not shown).

The manual sprocket 35 is a rotating body that manually feeds the carrier tape 80 along the tape transport path 31 in the transport direction X by an operator. The manual sprocket 35 is formed in a substantially circular plate shape and is rotatably supported relative to the cassette case 10. The manual sprocket 35 is disposed upstream in the transport direction X of the tongue 52 of the tape guide 50 in the tape transport path 31 (specifically, in the inclined portion of the tape transport path 31 whose position gradually increases from the upstream side to the downstream side in the transport direction X). The manual sprocket 35 rotates around a horizontal support shaft provided below the tape transport path 31 relative to the cassette case 10.

The manual sprocket 35 has external teeth that protrude radially outward. The external teeth of the manual sprocket 35 are provided at multiple angular intervals corresponding to the intervals of the feed holes 85 of the carrier tape 80. When the manual sprocket 35 is located near the top end of the manual sprocket 35, the external teeth protrude upward through the through holes of the tape transport path 31. When the external teeth protrude upward from the tape transport path 31, they engage with the feed holes 85 of the carrier tape 80. The manual sprocket 35 is rotated by the operator rotating the manual handle 36 that is integral with the manual sprocket 35. When the manual sprocket 35 rotates with the external teeth of the manual sprocket 35 engaged with the feed holes 85 of the carrier tape 80, the carrier tape 80 is transported in the transport direction X along the tape transport path 31.

The automatic sprocket 37 is a rotating body that automatically feeds the carrier tape 80 in the transport direction X along the tape transport path 31. The automatic sprocket 37 is formed in a substantially circular plate shape and is rotatably supported relative to the cassette case 10. The automatic sprocket 37 is disposed downstream in the transport direction X of the tongue portion 52 of the tape guide 50 in the tape transport path 31 (specifically, near the component supply position P). The automatic sprocket 37 rotates around a horizontal support shaft provided below the tape transport path 31 relative to the cassette case 10.

The automatic sprocket 37 has external teeth that protrude radially outward. The external teeth of the automatic sprocket 37 are provided at multiple angular intervals corresponding to the intervals of the feed holes 85 of the carrier tape 80. When the automatic sprocket 37 is located near the top end of the automatic sprocket 37, the external teeth protrude upward through the through holes of the tape transport path 31. When the external teeth protrude upward from the tape transport path 31, they engage with the feed holes 85 of the carrier tape 80. The automatic sprocket 37 also rotates when the motor engaged via the gear is intermittently driven to rotate a predetermined angle per drive. When the automatic sprocket 37 rotates with the external teeth of the automatic sprocket 37 engaged with the feed holes 85 of the carrier tape 80, the carrier tape 80 is pitch-fed and transported along the tape transport path 31 in the transport direction X.

The tape discharge section 60 is a discharge passage that discharges the carrier tape 80 from which the electronic components 2 have been removed from the cavities 83 of the base tape 81 to the outside of the cassette case 10. The tape discharge section 60 is provided inside the cassette case 10. The tape discharge section 60 is arranged and formed so as to extend from the top to the bottom at the front side of the cassette case 10 (specifically, downstream of the component supply position P in the transport direction X). After the electronic components 2 have been removed from the cavities 83 of the base tape 81 at the component supply position P, the carrier tape 80 is guided to the tape discharge section 60 with the base tape 81 and the cover tape 82 still adhered to each other at the other end in the tape width direction, and is discharged to the outside from the bottom of the cassette case 10.

2. Operation of the component supply device and tape guide In the component supply device 1, as shown in FIG. 8, in a normal state in which no external force F is applied to the tongue portion 52 by the operator, the tip height of the tip portion 52a of the tongue portion 52 is at a reference height.

Before the tip of the carrier tape 80 in the transport direction X inserted into the tape inlet of the component supply device 1 reaches the tongue portion 52 of the tape guide 50, the worker applies an external force F from above to below the tongue portion 52 through the opening 56a of the tape guide 50, thereby shifting the tip height of the tip portion 52a of the tongue portion 52 to a position lower than the reference height.

Specifically, the operator operates the manual handle 36 to rotate the manual sprocket 35 to transport the carrier tape 80 inserted into the tape inlet of the component supply device 1 in the transport direction X, while visually checking the transport direction leading end of the carrier tape 80 that has reached the opening 56a to confirm the boundary height position between the base tape 81 and the cover tape 82 and the state of the cover tape 82 relative to the base tape 81. The operator then selects an external force application position where the external force F should be applied from the mark display portion 55 on the upper surface of the tongue portion 52 according to the boundary height position, etc., and applies the external force F to the selected position to lower the tip height of the tip portion 52a below the reference height.

The application of the external force F is continued until the opposing portion 52b of the tongue portion 52 abuts against the stopper portion 54, and the abutting state is maintained until the tip portion 52a of the tongue portion 52 is inserted between the base tape 81 and the cover tape 82 at the tip of the carrier tape 80 in the transport direction X.

For example, when it is confirmed that the boundary height position is relatively high, the position of the mark display portion 55 marked with "H" is selected as the external force application position, an external force F is applied to that position, and the tongue portion 52 abuts against the upper portion 54aH of the stopper portion 54. When it is confirmed that the boundary height position is relatively low, the position of the mark display portion 55 marked with "L" is selected as the external force application position, an external force F is applied to that position, and the tongue portion 52 abuts against the lower portion 54aL of the stopper portion 54. When the tongue portion 52 abuts against the stopper portion 54, even if the external force F becomes even larger, the tongue portion 52 is restricted from moving further downward.

When the manual sprocket 35 is further rotated with the tongue portion 52 in contact with the stopper portion 54 by the application of an external force F and the carrier tape 80 is transported in the transport direction X, the tip portion 52a of the tongue portion 52 is inserted between the base tape 81 and the cover tape 82 at the tip of the carrier tape 80 in the transport direction X. 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 relative to the base tape 81 changes, the tip height of the tip portion 52a of the tongue portion 52 is changed according to the boundary height position, etc., so that 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 transport direction X.

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 transport direction X, the operator releases the application of the external force F downward to the tongue 52. When the application of the external force F is released, the tongue 52 deforms from its elastically deformed downward state to its original, approximately horizontal state, and the tip height of the tip 52a returns to the reference height.

When the tip height of the tip 52a of the tongue 52 returns to the reference height by removing the external force F as described above, the carrier tape 80 is transported in the transport direction X by the rotation of the manual sprocket 35 or the automatic sprocket 37, while the tongue 52 is maintained inserted between the base tape 81 and the cover tape 82, the blade 53 is inserted into the adhesive portion at one end of the tape width direction where the base tape 81 and the cover tape 82 are adhered. Therefore, when the tip height of the tip 52a of the tongue 52 returns to the reference height, the cover tape 82 is peeled off from the base tape 81 using the blade 53, thereby exposing the electronic component 2 in the cavity 83 of the base tape 81.

In this way, in the tape guide 50, the stopper portion 54 and the tongue portion 52 are formed so that the tip height of the tip portion 52a of the tongue portion 52 when the facing portion 52b of the tongue portion 52 abuts against the stopper portion 54 changes depending on the position where the external force F is applied on the upper surface of the tongue portion 52. Specifically, the lower surface of the tongue portion 52 (specifically, the facing portion 52b) that abuts against the stopper portion 54 is formed flat, and the upper surface of the stopper portion 54 that abuts against the tongue portion 52 is formed in a stepped shape. That is, the stopper portion 54 has a stepped portion 54a that is formed so that the upper surface height of the stopper portion 54 is gradually lowered from one end side of the tongue portion 52, i.e., the base side to the tip side.

In this configuration, the position where the external force F is applied on the upper surface of the tongue portion 52 changes in the extension direction of the tongue portion 52, so that the tip height of the tip portion 52a of the tongue portion 52 when the tongue portion 52 abuts against the stopper portion 54 can be changed up and down. Therefore, unlike a 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 tip height of the tip portion 52a of the tongue portion 52 can be changed to correspond to various carrier tapes 80, so that the tip portion 52a can be appropriately inserted between the base tape 81 and the cover tape 82.

Furthermore, the variation in tip height of tip portion 52a of tongue portion 52 described above is not achieved by changing the magnitude of external force F applied to the upper surface of tongue portion 52, but is achieved by changing the external force application position at which external force F is applied on the upper surface of tongue portion 52 in the extension direction of tongue portion 52, and changing the abutment position of step portion 54a of stopper portion 54 with which tongue portion 52 abuts due to the application of external force F.

Therefore, the tip height of the tip 52a of the tongue 52 can be changed regardless of the magnitude of the external force F that presses down and elastically deforms the tongue 52, so that the tip height can be stably maintained and fixed at each height position. Therefore, the tape guide 50 allows the tip 52a of the tongue 52 to be accurately and appropriately inserted between the base tape 81 and the cover tape 82 in accordance with various carrier tapes 80.

In addition, the tip 52a of the tongue 52 of the tape guide 50 is positioned at a tip height lower than the reference height immediately before insertion between the base tape 81 and the cover tape 82 of the carrier tape 80, and is returned to the reference height after the insertion. In this configuration, the difference in height between the tip 52a of the tongue 52 and the electronic component 2 in the cavity 83 of the base tape 81 can be increased in the vertical direction 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, compared to a structure in which the tip height of the tip 52a of the tongue 52 is maintained lower than the reference height even after insertion between the base tape 81 and the cover tape 82 of the carrier tape 80. Therefore, it is possible to prevent the electronic component 2 from contacting the corner of the tip 52a of the tongue 52.

Therefore, according to the tape guide 50, the tongue portion 52 can be appropriately inserted between the base tape 81 and the cover tape 82 at the leading end of the carrier tape 80 in the transport direction X, while preventing the leading end 52a of the tongue portion 52 from contacting the electronic component 2 in the cavity 83 of the base tape 81 after the insertion. Therefore, after the leading end 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 transport direction X and the blade portion 53 peels the cover tape 82 from the base tape 81 to expose the electronic component 2 in the cavity 83 of the base tape 81, the electronic component 2 can be prevented from being scratched due to contact with the tongue portion 52.

In addition, the stopper portion 54 is the upper portion of the side wall portion 57 of the guide body portion 51. Therefore, a structure that restricts the positional movement of the tongue portion 52 can be easily realized without preparing a part separate from the guide body portion 51.

Furthermore, the upper surface of the tongue portion 52 is provided with a mark display portion 55 that indicates the correspondence between the external force application position where the external force F is applied by the operator and the tip height that the tip portion 52a reaches when the tongue portion 52 abuts against the stopper portion 54 due to the application of the external force F. This indirectly informs the operator that 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 when abutting against the stopper portion 54 is variable up and down, and also clearly conveys an indication of where on the upper surface of the tongue portion 52 to press down in order to move the tip height of the tip portion 52a of the tongue portion 52 from the reference height to the desired height position. This improves the convenience of the operator in applying the 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.

3. Modified Form Incidentally, 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. Then, the blade portion 53 of the component exposure device 40 is inserted into the adhesion portion between the base tape 81 and the cover tape 82 to partially peel off the cover tape 82 from the base tape 81, thereby exposing the electronic component 2.

However, the present disclosure is not limited thereto, and may be applied to a configuration in which the cover tape 82 is opened without peeling the cover tape 82 from the base tape 81 at the adhesive portion to expose the electronic component 2 in the cavity 83. For example, instead of using the blade portion 53 provided on the tongue portion 52 to peel the cover tape 82 from the base tape 81, a cutter with a blade facing in the vertical direction may be used to split the cover tape 82 in two in the tape width direction to expose the electronic component 2 in the cavity 83.

In the above embodiment, the upper surface of the stopper portion 54 against which the tongue portion 52 abuts is formed in a stepped shape, and the stopper portion 54 has a stepped portion 54a made up of three flat portions. However, the present disclosure is not limited to this, and the stopper portion 54 may have a stepped portion 54a made up of two or four or more flat portions.

In addition, in the above embodiment, in order to change the tip height of the tip portion 52a of the tongue portion 52 when the tongue portion 52 abuts against the stopper portion 54 depending on the position at which an external force is applied on the upper surface of the tongue portion 52, the lower surface of the tongue portion 52 that abuts against the stopper portion 54 is formed flat, and the upper surface of the stopper portion 54 that the tongue portion 52 abuts against is formed stepped.

However, the present disclosure is not limited to this. Conversely, the upper surface of the stopper portion 54 against which the tongue portion 52 abuts may be formed flat, and the lower surface of the tongue portion 52 against which the upper surface of the stopper portion 54 abuts may be formed in a stepped shape. In this modified form, the tongue portion 52 has a stepped portion 52c formed so that the lower surface height increases stepwise from the base side to the tip side of the tongue portion 52. As shown in FIG. 14, the stepped portion 52c is formed so that three substantially horizontal flat portions are provided, for example, at the top, middle, and bottom. These three flat portions are, from the top, the upper step portion 52cH, the middle step portion 52cM, and the lower step portion 52cL. The stepped portion 52c may be formed in the opposing portion 52b where the tongue portion 52 abuts against the stopper portion 54.

In the above-described modified form, when the external force F is applied to the base side of the tongue 52, the tongue 52 can bend and elastically deform until the lower step 52cL abuts against the stopper 54, and even if the external force F becomes larger after the abutment, the tongue 52 cannot bend downward beyond that. In this abutment state, the tip height of the tip 52a of the tongue 52 is the upper step height. Also, when the above-described external force application position is halfway between the base side and the tip side of the tongue 52, the tongue 52 can bend and elastically deform until the middle step 52cM abuts against the stopper 54, and even if the external force F becomes larger after the abutment, the tongue 52 cannot bend downward beyond that. In this abutment state, the tip height of the tip 52a of the tongue 52 is the middle step height. Furthermore, when the above-mentioned external force application position is on the tip 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, and after that abutment, it cannot bend downward beyond that point even if the external force F becomes even larger. In this abutment state, the tip height of the tip portion 52a of the tongue portion 52 becomes the lower step height.

Even in the above modified form, the position at which external force F is applied on the upper surface of tongue portion 52 changes in the extension direction of tongue portion 52, so that the tip height of tip portion 52a of tongue portion 52 when tongue portion 52 abuts against stopper portion 54 can be changed up or down, thereby achieving the same effect as in the above embodiment.

In the above embodiment, in order to change the tip height of the tip 52a of the tongue 52 when the tongue 52 abuts against the stopper 54 according to the position of application of an external force on the upper surface of the tongue 52, the lower surface of the tongue 52 that abuts against the stopper 54 is formed in a flat shape, and the upper surface of the stopper 54 that the tongue 52 abuts against is formed in a stepped shape. However, the present disclosure is not limited to this, and as shown in FIG. 15, the lower surface of the tongue 52 that abuts against the stopper 54 may be formed in a flat shape, and the upper surface of the stopper 54 that the tongue 52 abuts against may be formed in an arc-convex shape from the base side to the tip side of the tongue 52. Conversely, the upper surface of the stopper 54 that the tongue 52 abuts against may be formed in a flat shape, and the lower surface of the tongue 52 that abuts against the stopper 54 may be formed in an arc-convex shape from the base side to the tip side of the tongue 52. With this configuration as well, the same effects as those of the above modified embodiment can be obtained.

In the above embodiment, the external force F applied to the upper surface of the tongue portion 52 is a pressing force applied by an operator. However, the present disclosure is not limited to this, and as shown in Figures 16 and 17, the tape guide 50 may include a clamp portion 58 that generates the external force F applied to the upper surface of the tongue portion 52.

In the above-described modified form, the clamp portion 58 generates a force that clamps the stopper portion 54 and the tongue portion 52 in the vertical direction as the above-described external force F. The clamp portion 58 is formed in a U-shaped cross section and has a side wall portion 58a, a lower wall portion 58b extending from the lower end of the side wall portion 58a, and an upper wall portion 58c extending from the upper end of the side wall portion 58a and facing the lower wall portion 58b. The clamp portion 58 is elastically deformable between the lower wall portion 58b and the upper wall portion 58c, and elastically deforms so as to narrow the two wall portions 58b, 58c when the lower wall portion 58b and the upper wall portion 58c are separated from each other by more than a predetermined distance.

The guide body 51 of the tape guide 50 has a clamp guide 57a that holds the clamp 58 slidably in the extension direction of the tongue 52. The clamp guide 57a is provided on the side wall 57 and extends like a rail along the extension direction of the tongue 52, i.e., the transport direction X. The clamp guide 57a is formed to be inclined or curved so that its position becomes lower from the base side to the tip side of the tongue 52.

The clamp portion 58 is held so as to be slidable in the extension direction of the tongue portion 52. The lower wall portion 58b of the clamp portion 58 is supported below the clamp guide portion 57a so as to be aligned with the clamp guide portion 57a. The upper wall portion 58c of the clamp portion 58 is supported above the tongue portion 52 so as to be aligned with the upper surface of the tongue portion 52. The clamp portion 58 generates an external force F that presses the tongue portion 52 against the stopper portion 54 between the lower wall portion 58b and the upper wall portion 58c, thereby clamping the tongue portion 52 and the stopper portion 54.

When the holding position at which the clamp portion 58 is held in the extension direction of the tongue portion 52 changes, the external force application position at which the clamp portion 58 applies the external force F to the upper surface of the tongue portion 52 changes, the position of the step portion 54a of the stopper portion 54 against which the tongue portion 52 abuts changes, and the tip height of the tip portion 52a of the tongue portion 52 when the tongue portion 52 abuts against the stopper portion 54 changes. Therefore, with this modified form, the same effect as with the modified form described above can be obtained.

In the above modified embodiment, the stopper portion 54 and the tongue portion 52 are formed so that the tip height of the tip portion 52a of the tongue portion 52 when the tongue portion 52 abuts against the stopper portion 54 changes depending on the position at which the external force F is applied on the upper surface of the tongue portion 52. 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 stepped portion 54a of the stopper portion 54 against which the tongue portion 52 abuts changes as the holding position of the clamp portion 58 in the extension direction of the tongue portion 52 changes.

However, the present disclosure is not limited thereto, and the tip height of the tip 52a of the tongue 52 may change depending on the position where the external force F is applied on the upper surface of the tongue 52, without providing a stopper portion 54 against which the tongue 52 abuts when it is elastically deformed. For example, as shown in Figures 18 and 19, the tape guide 50 may include a clamp portion 90 that applies an external force F to the upper surface of the tongue 52, causing the tongue 52 to elastically deform.

In the above modified embodiment, the clamp portion 90 is formed in a U-shaped cross section and has a side wall portion 90a, a lower wall portion 90b extending from the lower end of the side wall portion 90a, and an upper wall portion 90c extending from the upper end of the side wall portion 90a and facing the lower wall portion 90b. The clamp portion 90 is configured so that there is no elastic deformation between the lower wall portion 90b and the upper wall portion 90c, i.e., the distance between the two wall portions 90b and 90c does not change.

The guide body 51 of the tape guide 50 has a clamp guide 57b that holds the clamp 58 slidably in the extension direction of the tongue 52. The clamp guide 57b is provided on the side wall 57 and extends like a rail along the extension direction of the tongue 52, i.e., the transport direction X. The clamp guide 57b is formed to be inclined or curved so that its position becomes lower from the base side to the tip side of the tongue 52.

The clamp portion 90 is held slidably in the extension direction of the tongue portion 52. The lower wall portion 90b of the clamp portion 90 is supported on the lower side of the clamp guide portion 57b so as to be aligned with the clamp guide portion 57b. The upper wall portion 90c of the clamp portion 90 is supported on the upper side of the tongue portion 52 so as to be aligned with 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 set to be smaller than the distance between the upper surface of the tongue portion 52 and the lower surface of the clamp guide portion 57b in a normal state in which no elastic deformation occurs. While being supported by the clamp guide portion 57b at the lower wall portion 90b, the clamp portion 90 applies an external force F to the upper surface of the tongue portion 52 at the upper wall portion 90c, which causes the tongue portion 52 to elastically deform. The external force F applied by the clamp portion 90 to the tongue portion 52 is a reaction force accompanying the elastic deformation of the tongue portion 52.

When the holding position at which the clamp portion 90 is held in the extension direction of the tongue portion 52 changes, the external force application position at which the clamp portion 90 applies the external force F to the upper surface of the tongue portion 52 changes, and the tip height of the tip portion 52a of the tongue portion 52 changes. Specifically, the tip height of the tip portion 52a of the tongue portion 52 becomes lower as the external force application position moves closer to the tip side of the tongue portion 52. Therefore, with this modified form as well, the same effect as with the modified form described above can be obtained.

Furthermore, in the above embodiment, the component supply device 1 is a cassette-type tape feeder whose main body is covered by a cassette case 10. However, the present disclosure is not limited to this, and the component supply device 1 may be applied to a tape feeder other than a cassette-type tape feeder.

This disclosure is not limited to the above-described embodiments and variations, and various modifications may be made without departing from the spirit and scope of the invention.
