  The number of electrical components such as an IC chip that is finally bonded to an electrical work such as an LCD via an ACF is determined according to the type and function of the electrical work. For this reason, some electrical workpieces have one electrical component that is permanently crimped to the electrical workpiece via the ACF in the width direction of the cushioning tape. Some may have more than one in the direction.

  These electrical workpieces having different numbers of electrical components are sent to the first and third steps described above. For this reason, in order to be able to work on these electrical workpieces, in the work of the first step and the work of the third step, using a wide cushioning material tape having a large width dimension, As a result, it is possible to cope with an electrical work having the maximum number of electrical parts.

  According to this, for an electrical work having a small number of electrical parts, most of the cushioning material tape becomes a useless part that is not effectively used.

  An object of the present invention is to provide a connecting device for a shock-absorbing tape supply device that can reduce wasteful portions that are not used effectively, and can improve the effective use efficiency of the shock-absorbing tape. There is a place to do.

  The connecting device of the buffer material tape supply device according to the present invention is for connecting the electrical component to the electrical work to which the electrical component is crimped via the ACF, or to the electrical work. A buffer material tape is disposed between the electrical work and a head member that is movable toward the electrical work for attaching the ACF, and a source of the buffer material tape A shock-absorbing tape supply device is provided, which includes a feeding shaft on which a side portion is wound, and a take-up shaft for winding a destination-side portion of the shock-absorbing tape, and the shock-absorbing tape supply device A plurality of the buffer material tape supply devices having a space in which the buffer material tape supply devices are arranged in the width direction of the buffer material tape. Respectively it is characterized in that is detachable.

  The apparatus according to the present invention is provided with a space in which a plurality of buffer material tape supply devices are arranged and set in the width direction of the buffer material tape. Each of the tape supply devices is detachable. For this reason, the buffer material tape supply apparatus to be used can be selected, and the selected buffer material tape supply apparatus can be set to the apparatus which concerns on this invention. Thereby, it is possible to effectively cope with each electrical work in which the number of electrical parts to be crimped to the electrical work via the ACF is different in the width direction of the buffer tape. And the useless part which is not used effectively, which occurs in the buffer material tape can be reduced, and the effective utilization efficiency of the buffer material tape can be improved.

  In order to run the buffer material tape of the buffer material tape supply device from the feeding shaft side to the winding shaft side, the device according to the present invention rotates the winding shaft in the direction of winding the buffer material tape. A take-up shaft rotation drive member is provided. The number of the rotation drive members for the take-up shaft may be a plurality provided for each shock-absorbing tape supply device, or may be a common one for these shock-absorbing tape supply devices. Good.

  In the latter case, the apparatus according to the present invention is provided with one take-up shaft rotation drive member for rotating the take-up shaft of the shock-absorbing material tape supply device in the direction of winding up the shock-absorbing material tape. The length direction of the take-up shaft rotation drive member is defined as the width direction of the buffer material tape. As a result, the buffer material tape can be wound around the winding shafts of the plurality of buffer material tape supply devices arranged in the width direction of the buffer material tape from one rotary shaft rotation drive member. A rotational driving force can be transmitted.

  According to this, since it is not necessary to provide the take-up shaft rotation drive member for each shock-absorbing tape supply device in the device according to the present invention, the structure of the device according to the present invention can be simplified.

  Further, when the rotational driving force for winding the buffer material tape is transmitted from one rotary shaft rotation drive member to the winding shaft of each buffer material tape supply device, this rotational drive for the winding shaft The structure for rotating each winding shaft by the member may be an arbitrary structure. An example of this structure is a rotational drive for winding a cushioning material tape from a single winding shaft rotation driving member to each winding shaft via a cushioning material tape wound around these winding shafts. It is to allow power to be transmitted.

  When this structure is adopted, each take-up shaft can be moved forward and backward to the feed shaft side.

  According to this, even if the winding diameter of the buffer material tape on the take-up shaft increases due to the take-up shaft winding up the buffer material tape, the take-up shaft moves forward to the feed shaft side, so that one winding A rotational driving force for winding the buffer material tape can be transmitted from the rotary drive member for the winding shaft to the respective winding shafts via the buffer material tape wound around the winding shaft.

  In the apparatus according to the present invention, the above-described head member is moved backward after moving forward toward the above-described electrical work while pushing the buffer material tape of the buffer material tape supply device, so that the buffer material is loosened. Will occur. This slack must be removed by the time the head member moves forward and backward.

  In addition, the buffer material tape is connected to each of the supply shafts of the plurality of buffer material tape supply devices from the single rotation drive member for the supply shaft via the torque limiter provided for each of the buffer material tape supply devices. The rotational driving force for winding up is transmitted. Furthermore, when the head member moves forward toward the electric work while pushing the cushioning material tape, when the head member moves backward after moving forward, and when the head member stops at the retracted position reached by moving backward. When the head member is at least in the retracted position, the feed shaft rotation drive member is rotated.

  According to this, when the buffer material tape is slack, by rotating the feeding shaft rotation drive member, the buffer material tape is slack and this buffer material tape is not in tension, The rotation driving force of the rotation driving member for the feeding shaft is transmitted to each feeding shaft via the torque limiter. As a result, the shock-absorbing tape is wound around these feed shafts, and the slack of the shock-absorbing tape is removed. On the other hand, when the take-up shaft winds up the buffer material tape, the buffer material tape is in a tension state, and therefore, the torque drive between the rotary drive member for the feed shaft and the respective feed shafts is disconnected. The feed shaft performs rotation for feeding the buffer material tape.

  When the head member advances toward the electrical work by providing a one-way clutch that prevents the take-up shaft from rotating in the direction in which the buffer tape is fed out, the buffer tape when the head member advances toward the electrical workpiece. Is not fed out from the take-up shaft, and the buffer tape can be fed out from the feed shaft by the rotation of the feed shaft. Even when this feeding is performed, the buffer material tape is in a tensioned state, and therefore, the torque drive is disconnected between the feeding shaft rotary drive member and each feeding shaft.

  The arrangement position of each buffer material tape supply device in the apparatus according to the present invention may be a predetermined fixed position, or the arrangement position of each buffer material tape supply device is adjusted in the width direction of the buffer material tape. It may be free.

  According to the latter, since the arrangement position of the buffer material tape supply device can be adjusted in the width direction of the buffer material tape, each electric work in which the arrangement position of the electrical parts is different in the width direction of the buffer material tape is used. On the other hand, it can deal effectively.

  Further, each buffer material tape supply device may be set directly in the device according to the present invention, or each buffer material tape supply device is individually held in the device according to the present invention. By providing a plurality of holding members and holding the buffer material tape supply device on these holding members, each of the buffer material tape supply devices may be indirectly set in the device according to the present invention.

  When the latter is adopted and the arrangement position of each buffer material tape supply device in the device according to the present invention can be adjusted in the width direction of the buffer material tape, the device according to the present invention includes the buffer material tape. By providing at least one bar member having the width direction as the length direction and guiding each holding member to the bar member, the arrangement position of each holding member can be adjusted in the width direction of the cushioning tape. To do.

  Moreover, it is preferable that each holding member is provided with a position fixing means for fixing the arrangement position of these holding members to the position in the length direction of the bar member.

  According to this, the position of each holding member can be fixed at a predetermined position in the length direction of the bar member where the buffer material tape supply device held by these holding members should be arranged by the position fixing means, Thereby, each buffer material tape supply apparatus can be fixedly arranged at an accurate position in the length direction of the bar member.

  The apparatus according to the present invention can be used for the operation of crimping an electrical component to an electrical work via an ACF, and the apparatus according to the present invention can be used for attaching an ACF to an electrical work. Can also be used.

FIG. 8 shows a state where the take-up shaft 53 has advanced to the feed shaft 49 side.

  As shown in FIG. 7, a guide member 57 is fixed to the main body 41 in front of the slide arrangement space of the slide member 55, and the guides provided for the two left and right plate members 42 and 43 are provided. A bar member 58 is slidably inserted into the member 57, and a rear end portion of the bar member 58 is coupled to the slide member 55. A coil spring 59 is wound around the outer periphery of the bar member 58 between the slide member 55 and the guide member 57. For this reason, the slide member 55 is always slidably biased by the coil spring 59 in a direction in which the slide member 55 comes into contact with the stop portion 60 provided at the rear end of the main body 41.

  Further, guide rollers 61 to 64 are rotatably spanned between the two left and right plate members 42 and 43, and the cushioning material tape between the feeding shaft 49 and the winding shaft 53 of the cushioning material tape 52. The travel of 52 is guided by guide rollers 61-64. The buffer material tape 52 is a tape made of a buffer material formed of an elastic material such as urethane rubber.

  As shown in FIG. 6, the driven gear 65 is disposed on one side surface of the feeding shaft 49 between the two left and right plate members 42, 43, in other words, inside the main body 41 of the cushioning tape supply device 40. It is arranged on the side. The feed shaft 49 and the driven gear 65 are arranged coaxially, and the feed shaft 49 and the driven gear 65 are freely rotatable with respect to each other. Further, as shown in FIG. 7, a friction type torque limiter 66 for connecting the feeding shaft 49 and the driven gear 65 is disposed between the feeding shaft 49 and the driven gear 65. The limiter 66 is incorporated in the feed shaft 49.

  For this reason, when the buffer material tape 52 is not in a tension state, in other words, when the buffer material tape 52 is slackened, the driven gear 65 causes the feeding shaft 49 to wind the buffer material tape 52. 7, the shock-absorbing material tape 52 is taken up by the feeding shaft 49 to which the rotational driving force of the driven gear 65 is transmitted by the frictional force of the torque limiter 66. . When the driven gear 65 rotates in the direction A in FIG. 7 when the cushioning tape 52 is in a tension state, the driven gear 65 is illustrated with respect to the feeding shaft 49 due to slip generated in the torque limiter 66. 7 idles in the A direction. Further, when the tension state of the buffer material tape 52 is caused by the winding of the buffer material tape 52 by the winding shaft 53, the driven gear 65 that rotates in the direction A in FIG.

The anti-rotation means 70 includes a pin 71 spanned between the two plate members 42 and 43 and an anti-rotation member 72 that is rotatable about the pin 71. The rotation stopping member 72 has upper and lower two end portions 72A and 72B which are disposed on substantially opposite sides with respect to the pin 71. As shown in FIG. 7, when the upper end portion 72 </ b> A is engaged with the teeth of the driven gear 65, the driven gear 65 is prevented from rotating by the rotation stopping means 70. At this time, due to the position of the center of gravity of the rotation stopper member 72, the lower end 72 </ b> B of the rotation stopper member 72 reaches the same position as the position of the recess 47 formed in the main body 41.

  In the normal time described above, the feeding shaft 49 and the driven gear 65 are connected to each other by the frictional force of the torque limiter 66, so that the upper end portion 72 </ b> A of the rotation stopping member 72 is engaged with the teeth of the driven gear 65. Thus, the feeding shaft 49 can be prevented from rotating in the direction in which the buffer material tape 52 is fed out.

  Further, as shown in FIG. 7, between the winding shaft 53 and the central shaft 54 of the winding shaft 53, the winding shaft 53 is a direction in which the cushioning material tape 52 is fed out. A one-way clutch 73 is provided for preventing rotation in the B direction. By this one-way clutch 73 incorporated in the winding shaft 53, the winding shaft 53 rotates only in the direction opposite to the direction B in FIG.

  Next, the operation | work which crimps | bonds an electrical component to an electrical workpiece | work via ACF using the connecting apparatus 1 which concerns on this embodiment is demonstrated. In this operation, as shown in FIG. 1, three electrical components 81 are crimped to an electrical work 80 via an ACF 82.

  First, the respective head members 9 described above are moved to positions corresponding to the positions of the electrical components 81 by moving the respective slide structures 4 in the left-right direction. The positions of the holding members 26 described above are also moved to positions corresponding to the positions of the electrical components 81 by guiding the holding members 26 with the bar members 14 and 15 described above. The position of the above-described drive gear 31 disposed inside is also moved to a position corresponding to the position of the electrical component 81 by guiding the drive gear 31 to the drive shaft 21. Further, the position of the holding member 26 is fixed by the position fixing means 30 described above, and the position of the drive gear 31 is fixed by screwing the screw 32 described above. Thereafter, the buffer material tape supply device 40 formed as a cassette type is inserted and set in the internal space of each holding member 26.

  As shown in FIG. 2, the insertion set includes the bar member 15 in the recess 46 formed in the main body 41 of each device 40, the bar member 14 in the recess 47 formed in the main body 41, and the like. The driving shaft 21 is inserted into the recess 48 formed in the main body 41, respectively.

  FIG. 9 shows a case where the buffer material tape supply device 40 is inserted and set in the internal space of the holding member 26 as described above. In FIG. 9, the holding member 26 is omitted. When the device 40 is inserted and set into the internal space of the holding member 26, in other words, when the device 40 is held by the holding member 26, the bar member 14 that has entered the recess 47 is placed on the lower side of the anti-rotation member 72. Since the end portion 72B hits, the rotation preventing member 72 arranged in the device 40 swings around the pin 71, and the upper end portion 72A is disengaged from the teeth of the driven gear 65. That is, the rotation stopping of the driven gear 65 by the rotation stopping means 70 is released.

  When the device 40 is held by the holding member 26, the drive gear 31 disposed in the internal space of the holding member 26 meshes with the driven gear 65. Further, since the slide member 55 and the winding shaft 53 provided in the device 40 are always urged rearward by the coil spring 59 described above, when the device 40 is held by the holding member 26, the winding is performed. The shaft 53 contacts the drive roller 25 described above. When the portion on the destination side of the cushioning material tape 52 is wound around the winding shaft 53, the winding shaft 53 comes into contact with the driving roller 25 via the portion on the destination side of the cushioning material tape 52. .

  For this reason, the rotational driving force of the drive shaft 21 can be transmitted to the driven gear 65 of the device 40 held by each holding member 26 via the drive gear 31. Further, the rotational driving force of the driving roller 25 can be transmitted to the winding shaft 53 of the device 40 held by each holding member 26. Accordingly, the drive shaft 21 serves as a feed shaft rotation drive member for transmitting a rotational drive force to the feed shaft 49 of the device 40 via the drive gear 31, the driven gear 65, and the torque limiter 66, respectively. Reference numeral 25 denotes a take-up shaft rotation drive member for transmitting a rotation drive force to the take-up shaft 53 of each device 40.

  The feed shaft rotation drive member 21 and the take-up shaft rotation drive member 25 have a length in which the width direction of the cushioning material tape 52 disposed in the device 40 is the length direction. Become. The length direction of the bar members 14 and 15 is the width direction of the buffer material tape 52.

  Further, when the devices 40 are held by the respective holding members 26, these devices 40 are arranged in the width direction of the cushioning material tape 52. Furthermore, these devices 40 are set by being connected to the connecting device 1 by holding the devices 40 on the respective holding members 26, and these devices 40 can be driven by the connecting device 1. It becomes a state. The arrangement positions of these devices 40 in the left-right direction in the connecting device 1 correspond to the positions in the left-right direction of the respective electric components 81 arranged on the electric work 80.

  In the following, the operation of the connecting device 1 executed by a computer for controlling the above-described cylinder 8 and the drive sources such as the first and second electric motors 16 and 17 will be described in the work set by the computer program. The description will be given in order.

  When the start switch of the connecting apparatus 1 is turned on, as shown in FIGS. 1 and 2, the slide table 83 on which the electrical work 80 is positioned and fixed is fixed to the holding member 26 by a transfer device (not shown). Sent to the space below. When the position of the electrical component 81 arranged on the electrical work 80 reaches a position directly below the head member 9, the movement of the slide table 83 stops. At this time, the electrical component 81 is temporarily crimped to the electrical workpiece 80 via the ACF 82 by the temporary crimping operation which is the work of the previous process.

  As described above, when the slide table 83 is sent to the space below the holding member 26 by the transfer device (not shown), the drive of the first electric motor 16 is started, whereby the drive shaft 21 rotates. Begin to. The rotation of the drive shaft 21 is performed until the predetermined work on the electric work 80 is completed, that is, the electric work 80 in which the electric component 81 is pressure-bonded via the ACF 82 is moved by the movement of the slide table 83. Continue until exhausted from the space below 26. And the rotation direction of the drive shaft 21 is a direction which rotates each driven gear 65 to the A direction of FIG.

  Further, when the position of the electrical component 81 arranged on the electrical work 80 reaches a position directly below the head member 9, each head member 9 is lowered by the operation of the cylinder 8, and these head members 9 are Then, it moves toward the electric work 80 while pushing the buffer material tape 52 of the buffer material tape supply device 40. As a result, as shown in FIG. 9, the electrical component 81 is pressed against the electrical workpiece 80 via the ACF 82 by the pressing force of the head member 9 via the cushioning material tape 52. Since the head member 9 is heated at this time, the conductive force in the ACF 82 existing between the electrode of the electrical component 81 and the electrode of the electrical work 80 is caused by the pressing force and heat from the head member 9. The particles are overlapped so as to connect these electrodes. Thereby, a conductive path for connecting the electrodes is formed in the ACF 82.

  Further, since the pressing force of the head member 9 acts on the electrical component 81 and the ACF 82 via the buffer material tape 52, the electrical component 81 is uniformly crimped to the electrical work 80 via the ACF 82. .

  When the above-described pressure bonding is performed by lowering each head member 9 to the lowest position, each head member 9 is raised by the operation of the cylinder 8 to return to the original position, in other words, with respect to the electric work 80. Return to the raised position.

  As described above, when the head member 9 moves up and down, the drive shaft 21 continues to rotate, and this rotation is transmitted to the driven gear 65 as rotating the driven gear 65 in the direction A in FIG. Therefore, the buffer material tape 52 is in a tensioned state due to the winding action of the feeding shaft 49 to which the rotational driving force from the driven gear 65 is transmitted via the torque limiter 66. Since the buffer material tape 52 in the tension state is pushed toward the electric work 80 by the descending head member 9, the torque limiter 66 disposed between the drive shaft 21 and the feeding shaft 49 is applied to the torque limiter 66. When the slip occurs, in other words, the drive shaft 21 and the feed shaft 49 are disconnected by the torque limiter 66, so that the feed shaft 49 is pulled by the tensile force acting on the tensioned shock absorbing tape 52. 7 rotates in the opposite direction to the A direction. For this reason, when the head member 9 is lowered, the cushioning material tape 52 is fed out from the feeding shaft 49.

  Since the take-up shaft 53 is provided with the one-way clutch 73 for preventing the take-up shaft 53 from rotating in the direction B in FIG. The buffer material tape 52 is not fed out from the take-up shaft 53.

  As described above, when the buffer material tape 52 is fed out from the feed shaft 49 by the head member 9 being lowered, the buffer material tape 52 is slackened when the head member 9 is raised. This slack must be removed by the time the head member 9 moves up and down to crimp the next electrical component to the electrical workpiece via the ACF.

  In the present embodiment, the drive shaft 21 rotates when the head member 9 moves up and down and when the head member 9 rises and stops at the original position. For this reason, the rotational driving force of the drive shaft 21 is continuously transmitted to the feed shaft 49 via the torque limiter 66. When the cushioning tape 52 is slackened when the head member 9 starts to rise, the drive shaft 21 and the feeding shaft 49 are connected by the torque limiter 66, so that the head member 9 reaching the lowest position is moved. When the head member 9 is raised to the original position and when the head member 9 is stopped at the original position, the slack of the cushioning material tape 52 causes the feeding shaft 49 to rotate in the direction A in FIG. Is removed. Further, after this removal is completed, the cushioning tape 52 is in a tension state, so that the driven gear 65, to which the rotational driving force is continuously transmitted from the drive shaft 21, is moved by the disconnection action of the torque limiter 66. It rotates idly with respect to 49, and the rotation of the feeding shaft 49 stops.

  When the above operations are completed, the slide table 83 is sent out from the space below the holding member 26 by the transfer device described above. Thereafter, the next slide table with another electric work positioned and fixed on the upper surface is sent to the space below the holding member 26, and the electric work positioned and fixed on the slide table is sent to the slide table. Thus, the head member 9 moves up and down, that is, moves forward and backward in the same manner as described above, so that the electrical component is crimped to the electrical work via the ACF. Then, this operation is repeated.

  As described above, when the slide table fed into the space below the holding member 26 is replaced, the drive roller 25 described above rotates by a predetermined amount by the drive of the second electric motor 17 described above. This rotation is transmitted to the winding shafts 53 of the respective buffer material tape supply devices 40 as rotating the winding shafts 53 in the direction opposite to the direction B in FIG. Also at this time, the buffer material tape 52 is in a tension state, the winding shaft 53 is wound, the torque limiter 66 is disconnected, and the feeding shaft 49 with respect to the driven gear 65 is moved in the direction opposite to the direction A in FIG. Due to the rotation, the cushioning tape 52 travels from the feeding shaft 49 side to the winding shaft 53 side by a predetermined amount. As a result, a new location of the buffer material tape 52 is supplied to a position directly below the head member 9.

  Further, when the cushioning material tape 52 is wound around the winding shaft 53 in this way, the winding diameter of the cushioning material tape 52 on the winding shaft 53 increases. As described above, the take-up shaft 53 can be moved back and forth toward the feed-out shaft 49 by the sliding action of the slide member 55, so that the cushioning tape 52 wound around the take-up shaft 53 is interposed therebetween. When the winding diameter increases, the winding shaft 53 to which the rotational driving force from the driving roller 25 is transmitted follows the increase in the winding diameter by advancing toward the feeding shaft 49 side. Will be able to. Then, the rotational driving force of the drive roller 25 is transmitted to the take-up shaft 53 through the portion of the cushioning material tape 52 taken up by the take-up shaft 53.

  FIG. 10 shows a case where an electrical work 80 in which two electrical components 81 are arranged is positioned and fixed to a slide table 83 that is fed into the space below the holding member 26. At this time, the operation of one head member 9 among the three head members 9 is stopped. Of the three cassette type buffer material tape supply devices 40 held by the three holding members 26, one device 40 is taken out from the holding member 26.

  Further, in FIG. 10, the interval between the two electrical components 81 is different from the interval between the two left and right electrical components 81 in each combination in FIG. For this reason, in the case of FIG. 10, the adjustment work for the distance in the left-right direction between the two head members 9 to be operated is performed by the movement in the left-right direction of the slide structure 4 including these head members 9. Also, the adjustment work for the distance in the left-right direction between the two holding members 26 that hold the buffer material tape supply device 40 is also performed by the movement of these holding members 26 in the left-right direction.

  As a result, the same work as described above with reference to FIGS. 1 and 2 can be performed on the electrical work 80 in which the two electrical components 81 are arranged.

  According to the connecting device 1 of the present embodiment described above, the connecting device 1 is provided with a space in which a plurality of buffer material tape supply devices 40 are set in the width direction of the buffer material tape 52. These buffer material tape supply devices 40 are detachable from the connecting device 1. For this reason, the buffer material tape supply apparatus 40 to be used can be selected, and the selected buffer material tape supply apparatus 40 can be set in the connecting apparatus 1. Thereby, it is possible to effectively cope with each electrical work 80 in which the number of electrical components 81 to be crimped via the ACF 82 is different in the width direction of the cushioning material tape 52. And the useless part which is not used effectively can be reduced generated in the buffer material tape 52, and the improvement of the effective use efficiency of the buffer material tape 52 can be aimed at.

  Further, in the present embodiment, the winding shaft 53 of each buffer material tape supply device 40 is moved by one drive roller 25 having a length in which the width direction of the buffer material tape 52 is the length direction. The cushioning material tape 52 is rotated in the winding direction. For this reason, the drive member for rotating these winding shafts 53 is sufficient with one drive roller 25, and the structure of the continuous attachment apparatus 1 can be simplified accordingly.

  In addition, a rotational driving force for winding the buffer material tape 52 is transmitted from the drive shaft 21 to the feed shaft 49 of each buffer material tape supply device 40 via the torque limiter 66. For this reason, the slack that occurs in the cushioning material tape 52 due to the head member 9 moving back and forth toward the electrical work 80 can be removed by the rotation of the feeding shaft 49.

  When removing the slack of the buffer material tape 52, the winding shaft 53 of each device 40 may be rotated in the direction opposite to the direction B in FIG. According to this, the slackness of the buffer material tape 52 can be removed by the rotation of both the feeding shaft 49 and the winding shaft 53. According to this, it is possible to remove slack at a high speed in a short time, and it is possible to improve the efficiency of work by the continuous device 1.

  Furthermore, in this embodiment, the feeding shaft 49 of each buffer material tape supply device 40 is moved by one drive shaft 21 having a length in which the width direction of the buffer material tape 52 is the length direction. The cushioning tape 52 is rotated in the winding direction. For this reason, only one drive shaft 21 is sufficient for the drive member that rotates these feed shafts 49, and the structure of the connecting device 1 can be further simplified.

  Further, the position of each buffer material tape supply device 40 can be adjusted in the width direction of the buffer material tape 52. For this reason, it is possible to effectively cope with each electrical work 80 in which the arrangement position of the electrical component 81 is different in the width direction of the cushioning material tape 52.

  In addition, each buffer material tape supply device 40 is set to the holding member 26 that can adjust the position of the buffer material tape 52 in the width direction. For this reason, by changing the arrangement position of each holding member 26 in the width direction of the buffer material tape 52, the arrangement position of each buffer material tape supply device 40 is changed to the arrangement position of the electrical component 81. It can be adjusted corresponding to each electrical work 80 that is different in the width direction.

  Furthermore, since each holding member 26 is provided with the position fixing means 30, the holding member 26 and the buffer material tape supply device 40 can be fixed at an accurate position in the width direction of the buffer material tape 52.

  The connecting device 1 according to the embodiment described above is used for crimping the electrical component 81 to the electrical work 80 via the ACF 82. However, the connecting device 1 is also used when attaching the ACF to the electrical work. The device 1 can be used.
