As a result, the component supply tape 1 arranged on the X1 direction side of the tape placement unit 10 is moved in the X2 direction by the tape drive unit 20 until the end 1d is detected by the tape detection unit 40 (to the welding position). .

  Next, in step S3 (see FIG. 10), as in the case of the component supply tape 1, the start end of the new component supply tape 2 is cut by an operator, so that an unnecessary portion (component E2 of the component supply tape 2 is The recesses 2a that are not arranged are removed. As a result, a start end 2 d for connecting to the end 1 d of the component supply tape 1 is formed on the component supply tape 2. Further, in step S2, the operator starts the top end of the top tape 2c from the contact portion 3 (butting portion 4) to a position separated by a predetermined distance in the direction in which the component supply tape 2 extends from the contact portion 3 (butting portion 4). Disconnected. In step S2, the component supply tape 2 is placed on the tape placement unit 10 of the splicing device 100 by the operator.

  Specifically, as shown in FIG. 12, the component supply tape 2 is arranged on the X2 direction side of the tape arrangement unit 10. More specifically, first, the handle portion 11i is grasped and the tape pressing portion 11c is pulled upward by the operator. As a result, a gap is generated between the tape receiving part 11a and the tape pressing part 11c. Next, the end portion on the Y1 direction side of the component supply tape 2 is placed on the tape receiving portion 11a by the operator through the generated gap. At this time, the end of the component supply tape 2 on the Y1 direction side is brought into contact with the tape receiving portion 11a by the operator so that the teeth of the sprocket 31 of the tape drive unit 30 and the feed hole 2e of the component supply tape 2 are engaged. Be placed. As a result, the component supply tape 2 is arranged in a state of being positioned in the width direction (Y direction). Next, the grip of the handle portion 11i by the operator is released. As a result, the tape pressing portion 11c is moved downward by the urging force of the urging portion 11h, and the end portion on the Y1 direction side of the component supply tape 2 arranged on the tape receiving portion 11a is moved from above by the tape pressing portion 11c. Pressed. As a result, the end portion on the Y1 direction side of the component supply tape 2 is held by the tape pressing portion 11c and the tape receiving portion 11a. Next, when the tape pressing portion 12b is moved in the Y1 direction by the operator, the end portion on the Y2 direction side of the component supply tape 2 is inserted into the groove portion 12d of the tape pressing portion 12b and held by the groove portion 12d. Is done. As a result, the component supply tape 2 is arranged on the X2 direction side of the tape arrangement unit 10.

  Next, in step S4 (see FIG. 10), a positioning start button (not shown) provided in the splicing device 100 is operated by the operator. As a result, the component supply tape 2 arranged on the X2 direction side of the tape placement unit 10 is moved in the X1 direction by the tape drive unit 30 until the start end 2d is detected by the tape detection unit 40 (up to the welding position). . As a result, in step S4, as shown in FIG. 13, the end 1d of the component supply tape 1 and the start end 2d of the component supply tape 2 are brought into contact with each other. Further, in a state where the end 1d of the component supply tape 1 and the start end 2d of the component supply tape 2 are abutted with each other, the end of the top tape 1c and the start end of the top tape 2c are cut, so that the cut top tape 1c is cut. A cut portion 81 having a predetermined cut length L1 is formed between the end of the cut and the start end of the cut top tape 2c.

  Next, in step S5 (see FIG. 10), a welding start button (not shown) provided in the splicing device 100 is operated by the operator. As a result, the contact portion 3 (butting portion 4) between the end 1 d of the component supply tape 1 and the start end 2 d of the component supply tape 2 is welded by the welding portion 51. Thereby, the component supply tape 1 and the component supply tape 2 are connected.

  In step S5, first, the tip 51c of the welded part main body 51b of the welded part 51 is moved from the lowered position where the tip 51c of the welded part main body 51b of the welded part 51 is not pressed against the contacted part 3 (butting part 4). The welded portion 51 is moved upward (in the Z1 direction) by the welded portion vertical drive unit 52 to the raised position where it is pressed against the butted portion 4). Next, in a state where the tip 51c of the welded part main body 51b of the welded part 51 is pressed against the contact part 3 (butting part 4), the ultrasonic vibrator 51a of the welded part 51 performs super Sound waves are generated. That is, in the state where the tip 51c of the welded part main body 51b of the welded part 51 is pressed against the contact part 3 (butting part 4), the welded part main body 51b is vibrated by the vibration of the ultrasonic vibrator 51a of the welded part 51. Next, when a preset welding time has elapsed, the generation of ultrasonic waves by the ultrasonic transducer 51a of the welded portion 51 is stopped. That is, when the vibration of the ultrasonic vibrator 51a of the welding part 51 is stopped, the vibration of the welding part main body 51b is stopped. As a result, the contact portion 3 (butting portion 4) between the terminal end of the carrier tape 1b and the starting end of the carrier tape 2b is welded from the carrier tape 1b and 2b side (Z2 direction side) with the cut portion 81 formed. The Thereby, the carrier tape 1b and the carrier tape 2b are connected.

  Further, when welding is performed by the welding part 51, the vicinity of the contact part 3 (butting part 4) is cooled by the cooling part 70. Specifically, heat in the vicinity of the contact portion 3 (butting portion 4) on the side of the top tape 1c and 2c is radiated by the heat radiating portion 71 configured by the pressing portion 11g of the tape pressing portion 11b. Further, the heat in the vicinity of the contact portion 3 (butting portion 4) on the carrier tapes 1b and 2b side is radiated by the cooling fluid blown out from the cooling fluid blowing portion 72.

  In step S 5, the contact portion 3 (butting portion 4) is welded by the welding portion 51 with a welding width W 3 that is smaller than the tape width W 1 of the component supply tape 1 (2). When welding the smallest component supply tapes 1 and 2 arranged in the splicing device 100, the welded part width W2 of the welded part 51 and the welded width W3 are the same, so the welded part body 51b of the welded part 51 is the same. The contact portion 3 (butting portion 4) is welded by the welded portion 51 simply by pressing the tip 51 c of the contact portion 3 against the contact portion 3. Therefore, in this case, the welded part 51 is not moved in the Y direction by the welded part lateral drive part 53. On the other hand, when welding the component supply tapes 1 and 2 larger than the smallest component supply tapes 1 and 2 arranged in the splicing device 100, the welding width W3 is larger than the welding width W2 of the welding portion 51. The welding part 51 is moved in the Y direction by the welding part lateral drive part 53 so that the contact part 3 (butting part 4) is welded with the welding width W3. At this time, the welding part 51 is moved in the Y direction by the welding part lateral driving part 53 at a preset moving speed.

  Moreover, in step S5, after welding by the welding part 51, from the raise position which presses the front-end | tip 51c of the welding part main body 51b of the welding part 51 to the contact part 3 (butting part 4), the welding part main body 51b of the welding part 51 is shown. The welded portion 51 is moved downward (Z2 direction) by the welded portion vertical drive unit 52 to a lowered position where the tip 51c is not pressed against the contact portion 3 (butting portion 4).

  Next, in step S6, the component supply tape 1 (2) after welding reversely rotates the sprocket 21 of the tape drive unit 20 (arrow) so that the contact portion 3 (butting portion 4) is discharged out of the splicing device 100. (The rotation in the direction opposite to the A1 direction) is moved in the X1 direction. At this time, the sprocket 31 of the tape drive unit 30 idles.

  Next, in step S7, as shown in FIG. 14, the connecting tape 82 is attached to the top tape 1c and the top tape 2c by the operator so as to straddle the contact portion 3 (butting portion 4). As a result, the top tape 1c and the top tape 2c are connected.

  The connecting tape 82 is a tape including a base material 82a that does not have adhesiveness and an adhesive material 82b that has adhesiveness and is formed on the base material 82a. The connecting tape 82 includes an adhesive portion 82c where the adhesive material 82b is formed on the base material 82a, and a non-adhesive portion 82d where the base material 82a is exposed without forming the adhesive material 82b on the base material 82a. Yes. The non-adhesive portion 82d has a length L2 that is greater than a predetermined cutting length L1 of the cutting portion 81.

  In step S7, the non-adhesive portion 82d of the connecting tape 82 is disposed at a position corresponding to the cutting portion 81, and the top tape 1c is disposed such that the adhesive portion 82c is disposed at a position corresponding to the top tapes 1c and 2c. The connecting tape 82 is attached to the top tape 2c by the operator.

  In the above, the contact portion 3 (butting portion 4) is discharged out of the splicing device 100 in step S6, and the contact portion 3 (butting portion 4) is discharged out of the splicing device 100 in step S7. The example in which the connection tape 82 is pasted has been described. However, in the present embodiment, the connection tape 82 may be attached in a state where the contact portion 3 (butting portion 4) is disposed in the splicing device 100. In this case, first, the contact portion 3 (butting portion 4) is moved in the splicing device 100 from the lower side of the pressing portion 11g of the tape pressing portion 11b to a position where the connecting tape 82 can be attached. That is, the contact part 3 (butting part 4) is moved from the position covered from above by the pressing part 11g of the tape pressing part 11b to the position exposed upward. Then, with the both ends in the width direction being held by the splicing device 100, the connecting tape 82 is connected to the top tape 1c and the top tape 2c so as to straddle the contact portion 3 (butting portion 4) exposed upward. Is pasted. As a result, the workability of the attaching operation of the connecting tape 82 can be further improved.

  In step S8, as shown in FIG. 10, the carrier tapes 1b and 2b are connected by welding, and the component supply tape 1 (2) in which the top tapes 1c and 2c are connected by the connecting tape 82 is the operator.
