Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a multi-wiring device for inserting and wiring coated wires of different diameters into an electronic circuit board.

Conventional structure and its problems Conventionally, devices for wiring to electronic circuit boards have a supply section that supplies one type of coated wire and an insertion head that inserts one type of wire. When inserting and wiring wires, it is necessary to have a special insertion head and replace the wire by an operator.
For the same electronic circuit board, it is necessary to perform the insertion process twice using the same device, and electronic circuit board design is constrained by consideration of the wiring order, making it difficult to support high-density wiring and cost reduction of electronic circuit boards. Moreover, the number of man-hours required for designing the electronic circuit board and replacing the insertion head is inevitably increased, and this method has the drawback of lacking speed.

OBJECTS OF THE INVENTION The present invention aims to eliminate the above-mentioned conventional drawbacks and provide a multi-wiring device that can freely insert and wire coated wires of different diameters into electronic circuit boards.

Structure of the Invention The multi-wiring device of the present invention has an X/Y/θ table that can hold and position an electronic circuit board, cut a coated wire, strip the sheathing, and simultaneously form it into an L shape, and at regular intervals. A pair of cutter units provided, a chuck unit pulls out a coated wire having a desired diameter from a plurality of coated wires of different diameters, and the other end of the wire is chucked with a fixed chuck unit to cut the cutter. The electronic circuit board has two sets of a supply device for supplying wire rods to the terminal unit and the pair of cutter units, an insertion head for inserting the lead wire into the electronic circuit board, and a caulking fixation of the lead wire inserted into the board. The cutter unit has an anvil portion consisting of a pair of cutter units, and a moving means for moving the two sets of cutter units to predetermined positions depending on the type of the wire rod.

This configuration eliminates the need to replace the insertion head, making it possible to wire different wire diameters in a single insertion process, allowing for flexible board design and speed, reducing the cost of the board and increasing the cost. This makes it possible to handle high-density wiring.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a board 1 according to one implementation method of the present invention, and FIG. 2 shows a multi-type wiring device. The operation of the multi-wiring device, which is provided with a θ table 3, an insertion head 4 for receiving and inserting a wire, an anvil portion 5 for caulking and fixing a lead wire, and a supply device 6 for supplying the wire, will be described below.

As shown in FIG. 3, a swinging frame 10 that can rotate around gears 8 and 9 is attached to the insertion head 4, and a motor 11 is attached to the swinging frame 10.
As a driving source, timing pulleys 12 and 13
and the ball screw 15 via the timing belt 14.
is installed so that it can be rotated and positioned.

Attached to the ball screw 15 are cutter units 18 and 19 for the small diameter wire 17 and cutter units 21 and 22 for the large diameter wire 20, which are slidable at a constant interval using the guide rail 16 as a guide. The motor 11 moves the wire parallel to the small diameter wire 17 and the large diameter wire 20 at a constant interval, and the cutter unit 21 can be switched to the cutter unit 18, and the cutter unit 22 can be switched to the cutter unit 19. creating a structure. Further, the small diameter wire 17 and the large diameter wire 20 are supplied by guides 24 and 25 fixed onto a slide plate 23, and the slide plate 23 can be switched using guide rods 26 and 27 as guides. First, the small diameter wire 17 is connected to the chuck unit 2.
8, it is pulled out by a certain distance in the chuck state, and at the same time, the fixed chuck unit 29 performs chuck to bring it into the tensioned state.
By raising the insertion head 7, the swinging frame 10 connects to the hit blocks 30, 31 with the racks 32, 33.
The lever 35 attached to the cutter units 18, 19, 21, 22 hits the shaft 34 fixed to the insertion head, and is guided by the cam 36 and rotates through the gears 8 and 9.
7 is pushed out below the cutter units 18, 19, 21, 22, and lowers the upper cutters 38, 39, thereby cutting the small diameter wire 17 while chucking it at the pushers 40, 41, 42, 43.
After performing and stripping and L-shape forming, the small diameter wire 17 is received. After the receiving is completed, the insertion head 7 is lowered, and the swing frame 10 is moved to the racks 32, 33,
The lower cutter 37 is returned to the vertical state via the gears 8 and 9, and the lower cutter 37 is also returned to the vertical state via the cam 36. Lower the insertion head 7 again to the top of the board 1, insert the L-shaped receiving lead wire into the insertion hole made in the board 1 with pushers 40, 41, 42, and 43, and expose it below the board. The lead wire is bent by the clinch claws 46, 47 of the clinch units 44, 45 of the anvil portion, and the insertion is completed. Thereafter, the cutter unit 1 is moved by the ball screw 15 using the motor 11 as a driving source.
8, 19 and cutter units 21, 22 are switched. On the other hand, the small diameter wire 17 and the large diameter wire 20 are switched via a ball screw 49 using a motor 48 as a driving source, and the chuck unit 2 is connected to the small diameter wire 17 similarly to the small diameter wire 17.
8, the upper cutters 50, 51 of the drawer cutter units 21, 22 are pulled out in the chuck state, and the lower cutters 52, 53 are used to push the pushers 54, 55,
At 56 and 57, the large-diameter wire 20 is held in a chuck-and-hold state and is cut, covered with a strip, and formed into an L-shape to complete the insertion and wiring into another insertion hole in the substrate 1.

Effects of the invention As described above, by having a cutter unit for wires with different diameters and switching them in a controlled manner, it is possible to easily perform various types of wiring, reduce the number of board design steps, and achieve high-density wiring and low board design. Can fully cope with cost reduction.
