In the removal process after splicing, the splicing device lifts the pair of carrier tapes with the splicing tape attached to the pair of carrier tapes and the base tape. As a result, the splicing tape is peeled off from the base tape while maintaining the state of being attached to the pair of carrier tapes. The splicing apparatus is required to perform a good splicing process so that the splicing tape does not peel off poorly in the take-out process.

It is an object of the present specification to provide a splicing apparatus capable of successfully peeling a slicing tape from a base tape in a splicing process.

In the present specification, a carrier tape transport device that transports a pair of carrier tapes in a direction of approaching each other along a tape transport path and a splicing tape that is attached across the back surfaces of the pair of carrier tapes are arranged at predetermined intervals. The base tape transport device that transports the base tape in a direction intersecting the transport direction of the pair of carrier tapes, and the pair of carrier tapes that are positioned at splicing positions in the tape transport path by the carrier tape transport device. The tape affixing device to which the splicing tape is affixed and the pair of carrier tapes to which the splicing tape is affixed by the tape affixing device are lifted upward from the tape transport path to peel the splicing tape from the base tape. When the portion and the lifting portion lift the pair of carrier tapes, the pair comes into contact with portions of the upper surface of the base tape located on both ends of the splicing tape in the width direction of the base tape. Disclosed is a splicing device including a regulating unit that regulates the upward movement of the base tape when the carrier tape is lifted.

According to such a configuration, when the lifting portion lifts the pair of carrier tapes, the restricting portion restricts the upward movement of the base tape. As a result, the splicing tape is maintained in a state of being attached to the pair of carrier tapes, and is gradually peeled off from the base tape whose upward movement is restricted. As a result, the splicing device can successfully strip the splicing tape from the base tape during the splicing process.

Hereinafter, embodiments in which the splicing apparatus is embodied will be described with reference to the drawings. The splicing device splices the pair of carrier tapes by sticking the splicing tapes on both sides with the ends of the pair of carrier tapes abutted against each other. The pair of carrier tapes, for example, one is an old tape in use and the other is a new tape for replenishment.

1. 1. Configuration of Splicing Device 10 As shown in FIG. 1, the splicing device 10 includes a device main body 11, an upper cover 12, a carrier tape transport device 13, a cutting device 14, a supply tape transport device 15, and a tape sticking device 16. And a control device 17. The device main body 11 is formed in a rectangular parallelepiped shape as an overall shape. The apparatus main body 11 is formed with insertion ports 111 into which carrier tape 90 (see FIG. 3) is inserted on both sides in the longitudinal direction (left-right direction in FIG. 1).

The two insertion ports 111 communicate with each other by a tape transport path 112 formed inside the apparatus main body 11. The tape transport path 112 is a groove extending in the left-right direction of the splicing device 10. The tape transport path 112 supports a pair of carrier tapes 90 to be spliced inserted from the respective insertion ports 111.

The upper cover 12 is a cover member that opens and closes with respect to the device main body 11. The upper cover 12 constitutes the upper surface of the tape transport path 112 in the closed state. The upper cover 12 opens a pair of spliced carrier tapes 90 so that they can be taken out in the open state. In the present embodiment, the upper cover 12 is provided with a pair of lifting portions 121. Each of the pair of lifting portions 121 is located below the tape transport path 112 in the closed state of the upper cover 12, as shown by the solid line in FIG. Further, as shown by the alternate long and short dash line in FIG. 2, the pair of lifting portions 121 rise together with the upper cover 12 when the upper cover 12 is changed from the closed state to the open state.

The carrier tape transport device 13 transports a pair of carrier tapes 90 inserted from the two insertion ports 111 along the tape transport path 112, respectively. Here, as shown in FIG. 3, the carrier tape 90 is a tape member that houses a large number of parts 93. The carrier tape 90 has a base tape 91 and a cover tape 92. A cavity 911 is formed in the base tape 91 at the center in the width direction (vertical direction in FIG. 3).

The cavity 911 is formed in a concave shape having a bottom. Cavities 911 are formed at regular intervals in the longitudinal direction of the base tape 91 (left-right direction in FIG. 3). Each cavity 911 houses one component 93. Further, the base tape 91 is formed with a feed hole 912 at one edge in the width direction. The feed holes 912 are formed at regular intervals in the longitudinal direction of the base tape 91. The feed hole 912 engages with the teeth of the sprocket 131 of the carrier tape transport device 13 and is used for transporting the carrier tape 90.

The cover tape 92 is formed of a thin film-like polymer film. Both ends of the cover tape 92 in the width direction are adhered to the upper surface of the base tape 91. As a result, the cover tape 92 closes the opening of the cavity 911. As a result, the component 93 housed in the cavity 911 of the base tape 91 is prevented from falling off.

The carrier tape transport device 13 rotates the sprocket 131 to transport the pair of carrier tapes 90 along the tape transport path 112. As a result, the carrier tape transfer device 13 positions the cut portion of the carrier tape 90 at the cutting position Pc. Further, the carrier tape conveying device 13 conveys the pair of cut carrier tapes 90 in a direction in which they approach each other, and positions the respective ends of the pair of carrier tapes 90 at the splicing position Ps. The above-mentioned "splicing position Ps" is a position provided at the central portion in the left-right direction of the splicing device 10, and is a position where the pair of carrier tapes 90 are connected by splicing.

The cutting device 14 cuts the pair of carrier tapes 90 inserted from the respective insertion ports 111 at predetermined cutting points. In the present embodiment, the cutting device 14 cuts the pair of carrier tapes 90 in a series of operations by the cutters 141 arranged corresponding to the two cutting positions Pc on the tape transport path 112. The cutting device 14 discards an unnecessary portion of the carrier tape 90 generated by the cutting process from a duct (not shown).

The supply tape transfer device 15 conveys the supply tape 80 (see FIG. 4) and exposes the splicing tape 83 from the supply tape 80 so that it can be attached in the splicing process. Here, the supply tape 80 is a tape member having a three-layer structure in which a plurality of splicing tapes 83 are sandwiched between the base tape 81 and the cover tape 82 (shown by a broken line in FIG. 4). The base tape 81 has an adhesive region At that holds a pair of splicing tapes 83 arranged at predetermined intervals, and a non-adhesive region An that is on both ends of the adhesive region At in the width direction of the base tape 81 and has no adhesiveness. And have.

Two of the front surface splicing tape 831 and the back surface splicing tape 832 (hereinafter, simply referred to as "a pair of splicing tapes 83") are attached to the adhesive region At of the base tape 81 at predetermined intervals. A plurality of feed holes 811 are formed at regular intervals along the longitudinal direction of the base tape 81 in the non-adhesive regions An located at both ends in the width direction of the base tape 81. The feed hole 811 engages with the teeth of the sprocket (not shown) of the base tape transfer device 151 of the supply tape transfer device 15 and is used for transporting the supply tape 80. The base tape transport device 151 transports the base tape 81 in a direction intersecting the transport direction (left-right direction in FIG. 1) of the pair of carrier tapes 90.

In the base tape 81, positioning holes 812 are formed along the width direction of the base tape 81. The positioning hole 812 is used to position the supply tape 80 with respect to the pair of carrier tapes 90 to be spliced. The cover tape 82 is a film member attached so as to cover a plurality of sets of splicing tapes 83 attached to the adhesive region At of the base tape 81. The cover tape 82 is conveyed, for example, by a cover tape conveying device 152 that rotates a pair of rollers that sandwich the cover tape 82.

Here, as shown in FIGS. 5 and 6, the supply tape transfer device 15 is provided with a guide member 153 at a predetermined position with respect to the device main body 11. The guide member 153 defines a peeling position Pe for peeling the cover tape 82 in the transport direction of the base tape 81 (left-right direction in FIG. 6). When the cover tape 82 is peeled from the base tape 81 at the peeling position Pe, the pair of splicing tapes 83 exposes the adhesive surface to the pair of carrier tapes 90 upward and is positioned at the splicing position Ps. It is in a state of straddling both ends of the carrier tape 90.

The tape sticking device 16 sticks a pair of splicing tapes 83 to the front surface and the back surface of the pair of carrier tapes 90. Specifically, the tape application device 16 folds back a part of the supply tape 80 with the pair of splicing tapes exposed (see FIG. 8). Then, the tape sticking device 16 presses the pair of splicing tapes 83 against the front surface and the back surface of the pair of carrier tapes 90 positioned at the splicing position Ps. As a result, the pair of splicing tapes 83 are in a state of being adhered to the pair of carrier tapes 90 by applying a predetermined pressing force.

After that, the pair of splicing tapes 83 are peeled off from the base tape 81 in the removal process after splicing, and are taken out from the splicing device 10 together with the pair of spliced carrier tapes 90. Details of the application processing and the removal processing of the pair of splicing tapes 83 will be described later.

The control device 17 is mainly composed of a CPU, various memories, and a control circuit. The control device 17 executes the splicing process based on a preset program or parameter. In the splicing process, the control device 17 appropriately sets the transport amount and the cutting portion of the carrier tape 90 based on the information output from various sensors, and controls the operation of the carrier tape transport device 13 and the cutting device 14.

2. 2. Detailed configuration of the tape affixing device 16 The tape affixing device 16 has a back surface pressing member 20 and a front surface pressing member that press the pair of splicing tapes 83 straddling both sides of the pair of carrier tapes 90 positioned at the splicing position Ps. 30 is provided. The back surface pressing member 20 presses the back surface splicing tape 832 attached to the back surface of the pair of carrier tapes 90. The surface pressing member 30 presses the surface splicing tape 831 attached to the surface of the pair of carrier tapes 90.

As shown in FIG. 5, the back surface pressing member 20 is fixed to the first elevating table 42, which will be described later. The back surface pressing member 20 contacts the back surface splicing tape 832 in the splicing process to apply a pressing force. The surface pressing member 30 is fixed to the swivel base 54 of the swivel device 50 described later. The surface pressing member 30 contacts the surface splicing tape 831 in the splicing process to apply a pressing force.

The back surface pressing member 20 and the front surface pressing member 30 are formed of, for example, a resin such as urethane, and are elastically deformed according to the pressing force applied to the pair of splicing tapes 83. A plurality of pin holes 21 and 31 are formed in the back surface pressing member 20 and the front surface pressing member 30, respectively. Second positioning pins 55 provided on the swivel base 54 are inserted into the plurality of pin holes 21 of the back surface pressing member 20. First positioning pins 43 provided on the first elevating table 42 are inserted into the plurality of pin holes 31 of the surface pressing member 30.

As shown in FIG. 5, the tape application device 16 includes a drive device 40. The drive device 40 moves the back surface pressing member 20 and the front surface pressing member 30 in the splicing process. The drive device 40 includes a cam drum 41 that is rotated by a motor (not shown) that is a drive source. The cam drum 41 is rotatably supported by the apparatus main body 11 around an axis parallel to the transport direction of the carrier tape 90. The rotation speed and angle of the cam drum 41 are controlled by controlling the driving state of the motor by the control device 17.

A plurality of cam surfaces 411 are provided on the side surface of the cam drum 41. The plurality of cam surfaces 411 are formed in different shapes from each other, and raise and lower the first elevating table 42 and the second elevating table 44 and drive the swivel device 50. The first lift 42, the second lift 44, and the swivel device 50 each return to the initial state at the origin angle of the cam drum 41. The first lift 42 is arranged below the splicing position Ps.

The back surface pressing member 20 is fixed to the upper surface of the first lift 42. Further, a plurality of first positioning pins 43 are provided on the upper surface of the first lift 42. The plurality of first positioning pins 43 engage with the positioning holes 812 (see FIG. 3) of the base tape 81 and the feed holes 912 of the carrier tape 90 that penetrate the back surface splicing tape 832 in the splicing process.

The swivel device 50 swivels the front surface pressing member 30 with respect to the back surface pressing member 20. The back surface pressing member 20 and the front surface pressing member 30 can be switched between a state in which the pressing surfaces face each other and a state in which the pressing surfaces do not face each other by driving the swivel device 50. The swivel device 50 includes a rack base 51, a rack 52, a pinion gear 53, a swivel base 54, and a second positioning pin 55.

The rack base 51 is attached so that the vertical movement with respect to the second elevating base 44 is restricted and the horizontal movement is permitted. The rack base 51 moves in the horizontal direction when an arm (not shown) that engages with one of the plurality of cam surfaces 411 rotates due to the rotation of the cam drum 41. Further, the rack base 51 moves in the vertical direction as the second lift 44 moves up and down.

The rack 52 is fixed to the upper part of the rack base 51 so as to extend in the horizontal direction. The pinion gear 53 is rotatably provided on the second lift 44. The pinion gear 53 meshes with the rack 52 and rotates with the linear motion of the rack 52 that moves integrally with the rack base 51. Both ends of the swivel base 54 are supported so as to be able to swivel around the pinion gear 53 as the swivel center.

The surface pressing member 30 is fixed to the swivel base 54. Further, the swivel base 54 is provided with a plurality of second positioning pins 55. The plurality of second positioning pins 55 are arranged at positions different from the plurality of first positioning pins 43 of the first elevating table 42 in the transport direction of the carrier tape 90. The plurality of second positioning pins 55 engage with the positioning holes 812 (see FIG. 4) of the base tape 81 and the feed holes 912 of the carrier tape 90 formed side by side with the surface splicing tape 831 in the splicing process.

According to the above configuration, the rack base 51 moves in the horizontal direction integrally with the rack 52 as the cam drum 41 rotates. Then, the pinion gear 53 that meshes with the rack 52 rotates, and the swivel base 54 rotates with the rotation of the pinion gear 53. As a result, the front surface pressing member 30 rotates with respect to the back surface pressing member 20. As a result, the front surface pressing member 30 is switched to a state facing the back surface pressing member 20.

The second elevating table 44 uses the front surface pressing member 30 facing the back surface pressing member 20 as a part of the swivel device 50 (rack base 51, rack 52, pinion gear 53, swivel table 54, and second positioning pin 55). It is configured to be integrally movable with relative movement. The second lift 44 is arranged above the splicing position Ps in the splicing process. The second lift 44 moves integrally in the vertical direction together with a leg (not shown) that engages with one of the plurality of cam surfaces 411.

3. 3. Splicing process by the splicing device 10 The splicing process by the splicing device 10 will be described with reference to FIGS. 2, 6-9. Note that, in FIGS. 7-9, the thicknesses of the supply tape 80 and the carrier tape 90 are exaggerated (the same applies in FIG. 10). The splicing process is mainly composed of a cutting process for cutting a pair of carrier tapes 90, a sticking process for attaching the splicing tape 83 to the carrier tape 90 after cutting, and a taking-out process after splicing. The pasting process and the taking-out process in the splicing process will be described below.

Here, it is assumed that the ends of the pair of carrier tapes 90 are positioned at the splicing position Ps. In this state, when the supply tape 80 is moved in the transport direction by driving the supply tape transport device 15, the cover tape 82 is peeled from the base tape 81 at the peeling position Pe, as shown in FIGS. 6 and 7. It is folded back by the guide member 153. As a result, only the pair of splicing tapes 83 used in the sticking step executed immediately after is exposed. Further, the pair of splicing tapes 83 are positioned at predetermined positions in the transport direction.

Specifically, the feed hole 912 of the pair of carrier tapes 90 and the positioning hole 812 of the base tape 81 penetrating the back surface splicing tape 832 are positioned so as to be engaged with the first positioning pin 43. Further, the positioning hole 812 of the base tape 81 formed alongside the surface splicing tape 831 is positioned at a position where it can be engaged with the second positioning pin 55 of the swivel device 50.

The control device 17 rotates the cam drum 41 at a low speed. As a result, first, the first elevating table 42 and the second elevating table 44 rise, and the first positioning pin 43 and the second positioning pin 55 engage with the positioning hole 812 of the base tape 81. Next, as the rack base 51 moves horizontally, the swivel base 54 rotates, and the front surface pressing member 30 faces the back surface pressing member 20. At the same time, the surface splicing tape 831 is in a state of straddling the pair of carrier tapes 90.

The control device 17 further rotates the cam drum 41. As a result, the first lift 42 is further raised, and the second lift 44 and the swivel 54 are lowered. As a result, as shown in FIG. 8, the pair of carrier tapes 90 and the pair of splicing tapes 83 are sandwiched between the back surface pressing member 20 and the front surface pressing member 30. At this time, a predetermined pressing force is applied to the pair of splicing tapes 83, and they are attached to the back surface and the front surface of the pair of carrier tapes 90.

The control device 17 further rotates the cam drum 41. As a result, each member of the tape application device 16 operates in substantially the reverse order. As a result, as shown in FIG. 9, the back surface pressing member 20 moves so as to return to the initial position, and the first positioning pin 43 is separated from the positioning hole 812 of the base tape 81. Further, the surface pressing member 30 moves so as to return to the initial position, and the surface splicing tape 831 is peeled off from the base tape 81. Further, the second positioning pin 55 is separated from the positioning hole 812 of the base tape 81.

When the application process of the pair of splicing tapes 83 is completed as described above, the control device 17 executes the take-out process after splicing. This take-out process is a process of switching the upper cover 12 from the closed state to the open state so that the pair of carrier tapes 90 spliced from the apparatus main body 11 can be taken out. Further, the splicing device 10 lifts the pair of carrier tapes 90 upward from the tape transport path 112 in the take-out process.

The above-mentioned lifting in the take-out process corresponds to a peeling process of peeling the back surface splicing tape 832 attached to the base tape 81 from the base tape 81 immediately after the sticking process. More specifically, the control device 17 unlocks the upper cover 12 so as to switch the upper cover 12 from the closed state to the open state in the take-out process. As a result, the upper cover 12 is opened by the elastic force of the elastic member (not shown) arranged between the upper cover 12 and the apparatus main body 11.

As shown by the alternate long and short dash line in FIG. 2, the lifting portion 121 provided on the upper cover 12 rises together with the upper cover 12 when the upper cover 12 is opened, thereby transporting the pair of carrier tapes 90 to the tape. Lift upward from road 112. At this time, a certain amount of tension is applied to the base tape 81, and the back surface splicing tape 832 is peeled off from the base tape 81. When the peeling process is completed, the pair of spliced carrier tapes 90 are ready to be taken out from between the apparatus main body 11 and the upper cover 12.

4. Configuration of the regulating unit 154 and action in the peeling process In the peeling process, when the pair of carrier tapes 90 are lifted, the back surface splicing tape 832 is not peeled off from the pair of carrier tapes 90, and the back surface splicing is performed from the base tape 81. The tape 832 needs to be peeled off. Therefore, the back surface splicing tape 832 is managed so that the adhesive force with the carrier tape 90 is larger than the adhesive force with the base tape 81.

Further, the pair of splicing tapes 83 are managed so that the adhesive force with the base tape 81 is larger than the adhesive force with the cover tape 82. This is to prevent the pair of splicing tapes 83 from peeling from the base tape 81 together with the cover tape 82 when the cover tape 82 is peeled from the base tape 81. Therefore, the adhesive strength between the base tape 81 and the back surface splicing tape 832 needs to be secured to a extent that exceeds the adhesive strength between the cover tape 82 and the pair of splicing tapes 83.

However, depending on the storage state of the supply tape 80, the operating environment of the splicing device 10, the state of dirt on the back surface of the carrier tape 90, etc., the adhesive force between the base tape 81 and the back surface splicing tape 832 may be the result of the peeling process. May affect. Therefore, the splicing device 10 of the present embodiment adopts a configuration including a regulating portion 154 in order to satisfactorily peel the back surface splicing tape 832 from the base tape 81.

In the present embodiment, the regulation unit 154 is integrally provided with the guide member 153 of the supply tape transfer device 15 as shown in FIGS. 5 and 6. The regulating portion 154 extends from both ends of the guide member 153 in the width direction of the base tape 81 (vertical direction in FIG. 6) in the transport direction of the base tape 81 (horizontal direction in FIG. 6). In the present embodiment, the guide member 153 and the regulation portion 154 are integral members formed in a plate shape.

In the peeling process, the regulating portion 154 contacts the upper surface of the base tape 81 in the range Lp in which the back surface splicing tape 832 is arranged in the transport direction of the base tape 81. More specifically, the regulating unit 154 can come into contact with the base tape 81 in the contact range Lr extending from the peeling position Pe of the cover tape 82 defined by the guide member 153 in the transport direction of the base tape 81. Further, the regulating portion 154 contacts only the non-adhesive region An on which the feed hole 811 is formed on the upper surface of the base tape 81.

Further, the regulating unit 154 is arranged outside the movable range of the back surface pressing member 20 that gradually rises in the splicing process and the movable range of the front surface pressing member 30 that rises, turns, and descends in the splicing process. Further, the regulation unit 154 is arranged outside the movable range of the swivel device 50 that swivels the surface pressing member 30. With such a configuration, the regulating unit 154 is fixed at a position (outside the movable range) that does not interfere with the back surface pressing member 20, the front surface pressing member 30, and the swivel device 50 during the execution of the splicing process.

As shown in FIG. 10, the restricting unit 154 having the above configuration has both ends of the back surface splicing tape 832 in the width direction of the base tape 81 when the lifting unit 121 lifts the pair of splicing tapes 83 in the take-out process. Contact the part located on the side. As a result, the regulating unit 154 regulates the upward movement of the base tape 81 as the back surface splicing tape 832 is lifted.

Here, in the configuration without the regulating portion 154, when the pair of splicing tapes 83 to which the back surface splicing tape 832 is attached is lifted, the upward movement of the base tape 81 is restricted by the tension applied to the base tape 81. To. Then, the back surface splicing tape 832 is peeled from the base tape 81 from the long side parallel to the width direction of the base tape 81 toward the center of the short side.

On the other hand, in the configuration having the regulation portion 154 as in the present embodiment, when the pair of splicing tapes 83 to which the back surface splicing tape 832 is attached are lifted, they come into contact with both ends in the width direction of the base tape 81. The upward movement of the base tape 81 is regulated by the regulating unit 154. Then, the back surface splicing tape 832 is gradually peeled from the base tape 81 from the short side parallel to the transport direction of the base tape 81 toward the center of the long side.

As described above, if the peeling progress direction of the back surface splicing tape 832 with respect to the base tape 81 is different, the time from the start to the end of the peeling of the back surface splicing tape 832 is different. Therefore, in the embodiment in which the upward movement of the base tape 81 is restricted by the regulating unit 154, the amount of the back surface splicing tape 832 peeled off per unit time can be reduced. Therefore, in the peeling process, the force acting to peel off the back surface splicing tape 832 from the pair of carrier tapes 90 can be reduced.

According to such a configuration, a good adhesive state can be maintained even if the adhesive force between the pair of carrier tapes 90 and the back surface splicing tape 832 is reduced to some extent. As described above, the splicing device 10 of the present embodiment includes the regulating portion 154 that regulates the upward movement of the base tape 81 accompanying the lifting of the pair of carrier tapes 90 in the peeling process, so that the back surface splicing tape 832 is provided in the peeling process. Can be satisfactorily peeled off from the base tape 81.

Further, the regulating unit 154 contacts the base tape 81 in the contact range Lr including the range Lp in which the back surface splicing tape 832 is arranged in the base tape 81. According to such a configuration, the regulating unit 154 secures a sufficient length in the transport direction of the base tape 81, and can reliably regulate the upward movement of the base tape 81.

Further, the regulating portion 154 contacts only the non-adhesive region An on which the feed hole 811 is formed on the upper surface of the base tape 81. As a result, the regulating unit 154 regulates the upward movement of the base tape 81 without contacting the adhesive region At of the base tape 81. Therefore, when the base tape 81 is conveyed after the back surface splicing tape 832 is peeled off from the base tape 81, the regulating portion 154 can be prevented from adhering to the base tape 81.

5. Modifications of the Embodiment In the embodiment, the regulation unit 154 contacts the base tape 81 in the contact range Lr including the range Lp in which the back surface splicing tape 832 is arranged in the base tape 81. On the other hand, the regulating unit 154 sets various contact ranges Lr as long as it can contact the portions of the upper surface of the base tape 81 located on both ends of the back surface splicing tape 832 in the width direction of the base tape 81. Can be done.

Further, the regulating unit 154 may come into contact with a part of the adhesive region At of the base tape 81 as long as it does not affect the transportation of the base tape 81 or is small. However, from the viewpoint of more reliably reducing the influence on the transport of the base tape 81, the embodiment illustrated in the embodiment is preferable.

Further, the regulation unit 154 is appropriately set at a position where it is arranged as long as it does not interfere with the back surface pressing member 20 or the front surface pressing member 30. In the embodiment, the regulation unit 154 is configured to be integrally provided with the guide member 153.
