Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a radial taping component in which a lead wire of a radial lead type electronic component is taped with a backing tape and an adhesive tape, and a feed hole is provided in the tape portion. The present invention relates to a cutting device for radial taping parts, which cuts electronic components from a tape part of the tape part and also cuts the tape part into small pieces to facilitate the disposal of tape waste.

Generally, radial taping components are made by taping the lead wires 4 of a radial lead type electronic component (hereinafter referred to as radial component) 3 with a mount tape 1 and an adhesive tape 2, as shown in FIG. The structure was such that a feeding hole 5 was provided in the tape portion consisting of 2.

A conventional cutting device for cutting the radial component 3 of this type of radial taping component from the tape portion and supplying the radial component 3 for insertion into a printed wiring board has been constructed as shown in FIG.

That is, the rod 7 of the cylinder 6 pushes the lever 8, the feed pawl 9 provided on the opposite side of the lever 8 rotates the latch 10 by a certain angle, and the roller 12 having the pin 11 coaxially connected to the latch 10 is rotated. is rotated, the pin 11 is engaged with the feeding hole 5 of the tape part, and the radial taping part is conveyed.The radial part 3 that has been sent to the chucking position is moved by the chuck claw 14 of the transfer chuck 13 as indicated by the arrow C, respectively. When closing in the D direction, a cutter 15 attached to the tip of the chuck claw 14 cuts the lead wire 4 of the radial component 3 to separate it from the taped state.

According to such a cutting device for radial taping parts, tape waste 16 is generated by cutting off the radial part 3 as shown in FIG.
No. 6 was bulky and therefore extremely difficult to process.

Furthermore, since the cutter 15 is provided at the tip of the chuck pawl 14 of the transfer chuck 13, the structure becomes complicated and adjustment becomes difficult, and the cutter 15 generates sufficient force to cut the lead wire 4. Therefore, the dimensions of each part become larger, and the transfer chuck 13
Since the moment of inertia around the rotating shaft 17 also increases, the structure is disadvantageous for high-speed operation.

The present invention eliminates the drawbacks of the prior art as described above.

Embodiments of the present invention will be described below with reference to FIGS. 4 to 11.

First, the basic configuration of the present invention will be explained with reference to FIG. A lead cutter 20 is arranged and slides in the H direction and cuts the lead wire 4 of the radial component 3 with the flat cutter 19, and a lead cutter 20 is arranged in the vertical direction and slides in the I direction to cut the lead wire 4 of the radial component 3.
The flat cutter 19 includes a cylinder 22, a piston 23, and a compression spring 24. When air is supplied from the air inlet 25 of the flat cutter 19, the piston 23 releases the compression spring. A rod 26 is provided integrally with the piston 23 by sliding elastically on the piston 24.
When the rod 26 is made to protrude from the cut surface of the flat cutter 19 and the air supply is cut off, the piston 23 slides in the opposite direction due to the elastic force of the compression spring 24, and the rod 26 is moved into the flat cutter 1.
It is configured to be retracted from the cutting surface 9, and is configured to simultaneously cut radial taping parts that are intermittently conveyed to this cutting surface along the A-A line and the B-B line.

Note that both the lead cutter 20 and the tape cutter 21 are configured so that their tips are at an acute angle of 90 degrees or less,
Furthermore, in order to improve cutting reliability and facilitate adjustment, the lead cutter 20 and the tape cutter 21 are configured to slide independently.
Further, a transfer chuck 28 is disposed near the cutting portion and swings within a range of approximately 90 degrees around the rotating shaft 27.

The operation of such a cutting device for radial taping parts will be explained with reference to FIGS. 5 to 10.

When the radial component 3 is conveyed to the chucking position by some conveying device as shown in FIG. 5, the transfer chuck 28 closes to chuck the lead wire 4 as shown in FIG. followed by the seventh
As shown in the figure, the flat cutter 19 advances in the direction of arrow G and stops at a position where it touches the backing tape 1, and as shown in FIG.
1 moves forward in the directions of arrows H and J and cuts the L of the flat cutter 19.
The lead wire 4 and the tape portions 1 and 2 are cut by colliding with the letter-shaped protrusion 18 . Although the cut tape parts 1 and 2 may fall, they often do not fall because of the adhesive of the adhesive tape 2.

Therefore, as shown in FIG. 9, air is supplied to the cylinder 22 to move the piston 23, and the rod 2
6 is projected in the direction of arrow J, and the tape parts 1 and 2 are pressed in the direction of arrow J. Then, as shown in FIG. 10, the transfer chuck 28 transports the radial part 3 in the direction of arrow K, and when the rod 26 slides back to its original position, the tape parts 1 and 2 fall downward. Next, the flat cutter 19, the lead cutter 20, and the tape cutter 2.
1 slide back in directions opposite to the directions of arrows G, H, and I, respectively.

Further, FIG. 11 shows tape waste 29 cut by the above-mentioned cutting device, which is cut into extremely small pieces to facilitate post-processing.

Although it is possible to cut the lead wire 4 and the tapes 1 and 2 by integrating the lead cutter 20 and tape cutter 21 into an L-shaped cutter, in that case, the entire L-shaped tip of the integrated cutter Bringing the tip of the cutter 18 into contact requires precision, and if the precision is poor, either the lead wire 4 or the tapes 1 and 2 will not be cut. Furthermore, even if an integrated cutter can be manufactured with high precision, the lead wire 4, which is metal, and the tapes 1 and 2, which are not made of metal, are cut with the same cutter, so the tip of the cutter is likely to deform, and precision adjustment may be required many times. It becomes necessary. The present invention also solves the above problems by making the lead cutter 20 and tape cutter 21 separate.

Since the radial taping component cutting device of the present invention is configured as described above, it has the following effects.

(a) In the present invention, since the lead wire portion and the tape portion of the radial taping component are cut at the same time, the lead wire cutting device and the tape cutting device can be combined into one unit, making it possible to make the device compact. And, you only need one power source, etc.
The structure has become simpler. In addition, the cutting waste on the tape section was cut into pieces, making it very easy to dispose of it afterwards.

(b) In the present invention, the lead wire part and the tape part of the radial taping part are cut at the same time, so it may be difficult to adjust the cutters, but one cutter is integral, and the other cutter is a lead cutter and a tape cutter. Since the cutter is divided into two parts, each of which moves independently, adjustment is easy, the cutter is highly reliable, and the cutter can be easily resharpened.

(c) In the present invention, a cutter with a flat tip and a cutter with an acute angle of 90° or less are used to butt each other for cutting, which is likely to result in adhesive residue from the adhesive tape, but it is possible to incorporate a tape waste removal mechanism into one of the cutters. This actually improves reliability.

The present invention has the above-mentioned effects and advantages, and can be widely used for cutting radial taping parts, and at the same time can be widely applied to cutting in other fields.
