DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

This machine cuts and forms the linear conductor shown in Fig. 1 on a capobin (see Fig. 2) at a desired center/ter pitch on a printed circuit board, and then inserts and processes it. This is a dedicated insertion machine for barrier pull pitch jumper wires.

Figure 4 is a panoramic view of the V and D insertion machine. Reference numeral 1 designates a bobbin on which the jumper wire 2 shown in FIG. The pitch variable section 4 includes an insertion unit that cuts, shapes, and inserts the jumper wire 2 to an arbitrary pitch, and a jumper wire feeding unit that arbitrarily changes the feed of the jumper wire according to the arbitrary pitch.
The insertion unit and a variable pitch drive unit that changes the stopper of the jumper wire feeding Schnitt to an arbitrary length are integrated.

The insertion unit is given smooth movement by the cam and lever of the insertion head drive section 6. The printed circuit board 6 is placed under the insertion head section 3, and the printed circuit board 6 is placed directly under the insertion head section 3 at an arbitrary location on the printed circuit board. There is an XY table 7 that can bring out the jumper, and under the printed circuit board 6 there is an anobile part 8 that prevents the jumper from coming off and floating after it is inserted into the printed circuit board.

The insertion head will be described in detail with reference to FIG.

1 is the bobbin, 2 is the jumper wire, 3 is the insertion head, 4
is a pitch variable part, and 5 is an insertion head part. The insertion head part 5 is attached via a main body frame 1o and a ball bearing 11 so that it can freely rotate on a plane.

The insertion head section 5 is rotated by a rotatable rond end 13 attached to the head body shaft 12 and a body frame 10.
A rotational movement of 9C9 is performed by driving the cylinder 14 connecting the two. This allows arbitrary insertion in the X and Y directions. The center of the rotational movement is C in FIG. 6, which coincides with C shown in FIGS. 2 and 3, that is, the center of the guide groove 52.
It is the center of a'. That is, even if the insertion head rotates and inserts in the X direction and the Y direction, the rotation center coincides with the insertion hole on one side.

Inside the head body shaft, a lead receiver drive shaft 16 and an insertion unit drive shaft 16 are slidably supported. axis 1
5 and 16, levers 18 and 19 which are swung by rotating cams 17, respectively, can perform smooth up and down movements with regular intervals.

At the tip of the insertion unit drive shaft 1'5, there is a drive bracket 20 and a drive bar 21. As the drive bar 21 moves up and down, the pusher 518.51b of the insertion unit 50 moves up and down, cutting and forming the jumper wire. , perform the insertion.

A detailed view of the insertion unit 60 is shown in FIG.

As the pusher 51=1 supported by the drive bar 21 moves up and down, the insertion guide 52a and the movable blade 53 simultaneously begin to descend, and the jumper wire 2 is first cut by the blade portion 54' of the fixed blade 64 and the movable blade 63. .

After cutting, the insertion guide 52a and the pusher 51a descend together, and the lead holder moves between the tip 55' and the insertion guide 5.
2b, form the jumper wire lead into an L-shape. When the molding is completed, the lead receiver 55 is moved away in the direction of arrow P by the compression spring 57 as the drive cam 56 rises. After the lead receiver 55 escapes, the insertion guide 52b and the pusher 51a descend together to just above the printed circuit board 6, and then only the pusher descends and pushes the printed circuit board 6.
Insert the jumper wire into hole 6'. Plunger 51
The b1 insertion guide 52b and the lead wire guide 58 have roughly the same function as the aforementioned Pushinger 51a, etc., but unlike the movable blade 53, the lead wire guide 58 does not cut the jumper wire 2 as shown in FIG. In order to properly guide the Janno wire, one of which is free, to the guide groove 62ki of the insertion guide 62b, the wire is lowered. The aforementioned process diagram is shown in FIG. FIG. 8a shows the place where the jumper wire is cut, and FIG. 8b (l-i) shows the place where the cut jumper wire 2 is formed. FIG. 8C shows the insertion guide 5.
2a and 52b are directly above the printed circuit board 6,
FIG. 8d shows the state where only the pushers 51a and slb have been lowered and the jumper wire 2 has been inserted. Ball 59, ball groove 59a1, ball 60 cause the button shear, insertion guide, and movable blade to move differently depending on the vertical movement of the drive bar.
．． According to the ball groove 60a.

The vertical movement of the drive cam 56 in the lead receiver shown in FIG.

Although the pusher 51b is supported by the block 62,
The block 62 is fixed to the movable bracket 63 of the variable pitch section 4, and moves in the direction of arrow H shown in FIG.
The insertion pinch of the jumper wire can be varied.

The relationship between the variable pitch section 4 and the insertion unit 5o will be explained with reference to FIG.

A block 62 supporting the pusher 51b and the like is fixed to a bracket 63 that moves on a slide shaft 64, and its pitch changes.

The pusher 51a and the like are similarly supported by the fixed blade 54 and fixed to the variable pitch section main body 65.

The variable pitch drive section 7o will be explained with reference to FIG. FIG. 10 is a front view of FIG. 9, and the insertion unit 5o
This is a diagram with parts removed.

A ball screw 72 is rotated by a pulse motor 71, and the movable bracket 63 is arbitrarily moved via a ball screw nut 73 fixed within the movable bracket 63, thereby realizing a variable pitch.

Next, the jumper wire feeding unit 80 will be explained.

Pulse motor 1 rotated because the insertion pitch was variable, but
This movement is passed through the idle gear 8 to rotate the square screw 82, and the feed stopper 83 is moved in the direction of arrow S in FIG. The amount of movement is the same as that of the moving bracket 63 of the pinch variable section 4. By moving the feed stopper 83, the amount of movement of the jumper wire feeder 84 can be adjusted, and the amount of feed of the jumper wire 2 can also be changed in accordance with changes in the insertion wrench.

The feeder 84 slides on the slide shaft 86 by the movement of the feeder cylinder 85, and can send out only the length of the jumper wire that matches the insertion pitch.

The feeder 84 consists of a tapered portion 87, three to four balls 88, a ball presser 89, and a compression spring 9o. When the cylinder 85 moves in the direction of arrow S in FIG. When it bites in, is sent out in the T direction, and advances in the U direction, it is fixed by the return preventer 91 [the structure is the same as the sender 84], and only the sender 84 returns in the U direction.

Effects of the Invention As described above, the present invention is a jumper wire insertion device that automatically inserts at a desired pitch, and the change in insertion pitch and jumper wire feeding amount can be controlled by driving one motor of the insertion pitch conversion drive unit. The present invention provides an inexpensive and high-speed jumper wire insertion device that has a simple structure, is easy to maintain, and is easy to maintain.

Also, the density of electrical elements attached to printed circuit boards has increased, and C
As the number of circuit designs using AD increases, it is expected that jumper wires will increase in number in the future in order to produce the same effect as double-sided circuit boards. In addition, if the length of the jumper wires can be set and inserted at the appropriate length as shown in Figure 3, the degree of freedom in design will increase, making it easier to assemble circuits and increasing the density. It becomes easier to measure, and has significant practical effects.
