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 grip portion 11i is gripped and the tape pressing portion 11c is pulled upward by the operator. As a result, a gap is created between the tape receiving portion 11a and the tape pressing portion 11c. Next, the operator places the end of the component supply tape 2 on the Y1 direction side in the tape receiving portion 11a through the generated gap. At this time, the end of the component supply tape 2 on the Y1 direction side is attached to 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 holes 2e of the component supply tape 2 engage with each other. Will 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 Y1 direction end of the component supply tape 2 arranged in the tape receiving portion 11a is moved upward by the tape pressing portion 11c. It is held down. As a result, the end of the component supply tape 2 on the Y1 direction side is held by the tape pressing portion 11c and the tape receiving portion 11a. Next, the tape holding portion 12b is moved in the Y1 direction by the operator, so that the end portion of the component supply tape 2 on the Y2 direction side is inserted into the groove portion 12d of the tape holding portion 12b and held by the groove portion 12d. To be 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 on 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 arranging section 10 is moved in the X1 direction by the tape driving section 30 until the starting end 2d is detected by the tape detecting section 40 (up to the welding position). .. As a result, in step S4, as shown in FIG. 13, the terminal end 1d of the component supply tape 1 and the starting end 2d of the component supply tape 2 are brought into contact and abutted. Further, in the state where the end 1d of the component supply tape 1 and the start end 2d of the component supply tape 2 are butted against each other, the top tape 1c after cutting is cut because the end of the top tape 1c and the start end of the top tape 2c are cut. A cutting portion 81 having a predetermined cutting length L1 is formed between the end of the tape and the starting end of the top tape 2c after cutting.

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

In step S5, first, the tip 51c of the welding portion body 51b of the welding portion 51 is moved from the lowered position where the tip 51c of the welding portion body 51b is not pressed against the contact portion 3 (butting portion 4) to the contact portion 3 ( The welding portion 51 is moved upward (in the Z1 direction) by the welding portion vertical drive portion 52 to a raised position where it is pressed against the butted portion 4). Next, with the tip 51c of the welding portion main body 51b of the welding portion 51 being pressed against the contact portion 3 (butting portion 4), under the control of the control portion 60, the ultrasonic transducer 51a of the welding portion 51 performs ultrasonic waves. Sound waves are generated. That is, with the tip 51c of the welding portion main body 51b of the welding portion 51 being pressed against the contact portion 3 (butting portion 4), the welding portion main body 51b is vibrated by the vibration of the ultrasonic transducer 51a of the welding portion 51. Next, when a preset welding time elapses, the generation of ultrasonic waves by the ultrasonic transducer 51a of the welding portion 51 is stopped. That is, the vibration of the ultrasonic transducer 51a of the welded portion 51 is stopped, so that the vibration of the welded portion main body 51b is stopped. As a result, with the cut portion 81 formed, the contact portion 3 (butting portion 4) between the end of the carrier tape 1b and the start of the carrier tape 2b is welded from the carrier tape 1b and 2b side (Z2 direction side). It Thereby, the carrier tape 1b and the carrier tape 2b are connected.

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

In step S5, the contact portion 3 (butting portion 4) is welded by the welding portion 51 with a welding width W3 smaller than the tape width W1 of the component supply tape 1(2).

The contact portion 3 (butting portion 4) is welded by the welding portion 51 only by pressing the tip 51 c of the contact portion 3 against the contact portion 3. Therefore, in this case, the welding portion 51 is not moved in the Y direction by the welding portion lateral drive portion 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 portion width W2 of the welding portion 51. The welding portion 51 is moved in the Y direction by the welding portion lateral drive portion 53 so that the contact portion 3 (butting portion 4) is welded with the welding width W3. At this time, the welding portion 51 is moved in the Y direction by the welding portion lateral drive portion 53 at a preset moving speed.

Further, in step S5, after welding by the welding portion 51, the tip 51c of the welding portion main body 51b of the welding portion 51 is pressed against the contact portion 3 (butting portion 4) from the rising position to the welding portion main body 51b of the welding portion 51. The welding portion vertical drive unit 52 moves the welding portion 51 downward (Z2 direction) to a lowered position where the tip 51c is not pressed against the contact portion 3 (butting portion 4).

Next, in step S6, the welded component supply tape 1 (2) rotates the sprocket 21 of the tape drive unit 20 in the reverse direction (arrow) so that the contact portion 3 (butting portion 4) is discharged to the outside of the splicing device 100. It is moved in the X1 direction by being rotated in the direction opposite to the A1 direction). At this time, the sprocket 31 of the tape drive unit 30 idles.

Next, in step S7, as shown in FIG. 14, the operator attaches the connecting tape 82 to the top tape 1c and the top tape 2c 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 example in which the connection tape 82 is attached has been described. However, in the present embodiment, the connection tape 82 may be attached while the contact portion 3 (butting portion 4) is arranged in the splicing device 100. In this case, first, the contact portion 3 (butting portion 4) is moved in the splicing device 100 from below the holding portion 11g of the tape holding portion 11b to a position where the connecting tape 82 can be attached. That is, the contact portion 3 (butting portion 4) is moved from the position covered from above by the holding portion 11g of the tape holding portion 11b to the position exposed above. Then, in a state where both ends in the width direction are held by the splicing device 100, the connecting tape 82 is attached to the top tape 1c and the top tape 2c so as to straddle the contact portion 3 (butting portion 4) exposed above. Pasted by. This makes it possible to further improve the workability of the work of attaching the connecting tape 82.
