As described above, each of the fixing part, the upper jaw, the pressing handle, and the return link is hinged to form a four-section link mechanism. When the pressing handle 630 is operated, the upper jaw 620 is interlocked to open the state as shown in FIG. 10. And between closed states as shown in FIG. 11. In particular, in the closed state, the lower jaw 660 fixed to the upper surface of the frame 530 is engaged with the upper jaw 620, and the lower jaw 660 lowers the clip of the clip ribbon interposed between the upper jaw 620 and the lower jaw 660. The upper jaw 620 serves to support the pressing from the upper side of the clip. Therefore, the feeding tape is supplied so that the widthwise end where the index hole of the feeding tape is formed between the upper jaw 620 and the lower jaw 660 is positioned, and the clip ribbon C is placed so that the through hole of the clip overlaps the index hole. After supplying together, the pressing handle 630 is pressed to the closed state as shown in FIG. 11, and the teeth of the clip are bent as shown in FIG. 7 while the clip is pressed by the upper jaw 620 and the lower jaw 660. The ends of the two feeding tapes can be connected with a clip. When the force applied to the pressure handle is removed in the closed state, the splicing tool 600 returns to the open state by the restoring force of the elastic member 650. At this time, in order to secure the clip to be connected to the feeding tape in the correct position, as shown in Figure 14, the lower jaw 660 has an index pin 661 in accordance with the interval of the through hole of the clip, as in a typical splicing tool It is preferable that it is formed.

When the ratchet lever 546 reciprocates in accordance with the shape of the swing cam 545 rotating together with the feeding sprocket 540, the swing roller 547 in contact with the other end of the ratchet lever 546 moves up and down. Therefore, when the clip ribbon C passes by the swinging roller 547, the clip ribbon C is periodically moved up and down. The swing cam 545, the ratchet lever 546, and the swing roller 547 index the through holes of the clip when the index pin 661 is formed in the lower jaw 660 of the splicing tool 600. It is for convenience to insert the pin.

On the other hand, if the clip ribbon (C) used in this embodiment is the same as the first embodiment of the clip ribbon for feeding tape connection according to the present invention as described above, the splicing tool 600 is returned to the open state After the tape is removed, the feeding tape is connected. And if the clip ribbon (C) used in this embodiment is the same as the second embodiment of the clip ribbon for feeding tape connection according to the present invention as described above, the upper jaw 620 of the splicing tool 600 It is preferable to install the cutter 690 in the). It is preferable that the cutter 690 has a blade shape and is disposed in the width direction of the clip of the clip ribbon C to cut the notch 310 of the clip. The cutter 690 cuts the notch portion of the clip ribbon C when the splicing tool 600 is closed as shown in FIG. 14, thereby completing the connection of the feeding tape without the need for additional post processing. can do. At this time, since the teeth of the clip ribbon are already inserted into the index holes at the ends of the two feeding tapes, the two feeding tapes may be partially cut. However, even if the feeding tape is cut together, the cut portion is only a part of the widthwise edge, so the function of the feeding tape is maintained as it is. If the clip ribbon (C) used in the present embodiment is the same as the third embodiment of the clip ribbon for feeding tape connection according to the present invention, the cutter 690 is disposed in the longitudinal direction of the clip portion 400 to be cut It is preferable to cut 410. As described above, in this case, the feeding tape can be avoided to be cut together.

Since the present embodiment includes a pair of splicing tools 600 and a pair of clip drums 520 for providing a clip ribbon C to each splicing tool, index holes are formed at both ends in the width direction, respectively. In the case of connecting the feeding tape, a pair of splicing tools 600 are all used, and in the case of connecting the feeding tape in which the index hole is formed only at one end in the width direction, only one necessary splicing tool 600 is used.

FIG. 15 is a front view of a second embodiment of a surface mounting electronic component feeding tape connection device according to the present invention, FIG. 16 is a left side view of the embodiment of FIG. 15, FIG. 17 is an enlarged view of a portion A of FIG. 18 is a partial rear view of the embodiment of FIG. 15, and FIG. 20 is an enlarged view of the cutter of FIG. 18.

This embodiment further includes a friction disk 511 and a ball plunge 710 in the first embodiment. In addition, instead of using the feeding sprocket 540, swinging cam 545, ratchet lever 546 and rocking roller 547 to feed the clip to the splicing tool 600, the feeding sprocket 740, fixed disk 741 and spin drum 749 are used. In addition, the position of the cutter 790 is different from the case of the first embodiment. Therefore, except for the following case, since the structure is the same as that of the first embodiment, the first embodiment will be described and a detailed description thereof will be omitted.

The friction disk 511 is fixed to the frame 530 to contact the side of the component drum 510. Accordingly, the friction disk 511 provides a friction force on the side of the component drum 510 to prevent the component drum 510 from rotating under a certain limit. Since the component drum 510 is rotatably supported by the frame 530, the component drum 510 is rotated when the feeding tape is supplied to the splicing tool 600. In this case, even when the feeding tape is stopped to the splicing tool 600, the component drum 510 continues to rotate due to inertia. However, when the friction disk 511 is installed on the side of the component drum 510, since the friction force acts on the component drum 510, the supply of the feeding tape is stopped so that the component drum 510 does not have a rotational force. Rotation of 510 is also stopped. When the feeding tape is supplied to the splicing tool 600, the rotational force acts on the component drum 510, and the rotational force exceeds the frictional force acting between the friction disk 511 and the component drum 510. The component drum 510 rotates.

The ball plunge 710 is fixed to the frame 530 to apply a constant load to the side of the clip drum 520 to prevent the clip drum 520 from rotating under a certain limit rotation force. The ball plunger 710 has a housing 719, a ball 711, a spring 713, and an adjustment nut 715. The housing 719 has a through hole formed at an edge thereof and is fixed to the frame 520 and positioned at a side of the clip drum 520. The ball 711, the spring 713, and the adjusting nut 715 are located inside the through hole of the housing 519. The ball 711 applies a constant force to the clip drum 520 by the elastic force of the spring 713. The adjusting nut 715 may be coupled to the housing by screwing. Therefore, the elastic force of the spring 713 can be adjusted using the adjustment nut 715, it is possible to adjust the force applied to the clip drum 520. In addition, a separation prevention jaw 717 may be formed at the inlet of the through hole so that the ball 711 is not separated from the ball plunge 719.

The clip drum 520 is rotatably supported by the frame 530 similarly to the component drum 510 so that the clip ribbon C is continuously rotated by inertia even when the supply of the clip ribbon C to the splicing tool 600 is stopped. However, when the ball plunge 719 is installed to apply force to the clip drum 520, the rotation of the clip drum 520 is also stopped when the supply of the clip ribbon C is stopped.

In the first embodiment, the feeding sprocket 540, the swing cam 545, the ratchet lever 546, and the swing roller 547 are used to supply the clips to the splicing tool 600 one by one. In the following, a feeding sprocket 740, a fixed disk 741, and a spin drum 749 are used.

In the feeding sprocket 740, pins are formed on the outer circumferential surface at regular intervals so that the feeding sprocket 740 can be inserted into the index hole of the feeding tape and the through hole of the clip ribbon C as in the first embodiment, and rotates on the frame 530. It is possibly fixed. The fixed disk 741 is fixed to the frame 530 coaxially with the feeding sprocket 740. In addition, grooves 743 are formed on the outer surface of the fixed disk 741 at regular intervals on the concentric circles. The spacing between the grooves 743 is formed so that one clip can be supplied to the splicing tool 600 when the feeding sprocket 740 rotates from one groove to another neighboring groove. Therefore, when five grooves 743 are formed in the fixed disk 741 as in the embodiment, when the feeding sprocket 740 rotates once, five clips may be supplied to the splicing tool 600. Spin drum 749 is fixed coaxially to the feeding sprocket 740 between the feeding sprocket 740 and the fixed disk 741. Accordingly, when the feeding sprocket 740 rotates, the spin drum 749 also rotates in the same manner. The spin drum 749 is provided with a spring 745 and a spin ball 747 at positions corresponding to the grooves 743 of the fixed disk 741. The spin ball 747 is placed in the groove 743 of the fixed disk 741 by the elastic force of the spring 745. Rotating the feeding sprocket 740 also rotates the spin drum 749 together. Accordingly, the spin ball 747 mounted on the groove 743 of the fixed disk 741 is separated from the groove 743 and rotates along the outer surface of the fixed disk 741. At this time, when the feeding sprocket 740 continues to rotate to the next neighboring groove 743, the spinball 747 is placed on the next neighboring groove 743 and one clip is supplied to the splicing tool 600. . Therefore, the clips can be supplied to the splicing tool 600 one by one.

In this embodiment, the cutter 790 is installed in the lower jaw 660. The shape of the cutter 790 is the same as that of the first embodiment, and is disposed in the width direction of the clip ribbon (C). In addition, the elastic jaw 791 is installed in the upper jaw 620 at a position corresponding to the cutter 790. Therefore, when the splicing tool 600 is in the closed state, the elastic jaw 791 presses the clip ribbon C downward, and the notch portion of the clip ribbon C is cut by the cutter 790. Here, the elastic jaw 791 is preferably formed of an elastic material such as urethane.
