Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wire insertion device for sequentially inserting wires such as jumper wires into predetermined positions on a board.

2. Description of the Related Art Conventionally, this type of wire insertion device has been constructed as shown in FIGS. 8 and 9.

That is, a supply roller 3 that sends out a predetermined amount of the wire 2 supplied on the reel 1, a pulse motor 4 that rotates the supply roller 3 by a predetermined amount, and movement of the wire 2 between the feeding position and the forming position. A supply unit 7 has a swingable nozzle 6 for performing the swinging, a rotary cylinder 6 for swinging the nozzle 5, and a supply unit 7 for controlling the position of the wire rod 2 in the direction perpendicular to the axial direction of the fed wire rod 2. A pusher 10 has a V-groove 8 for receiving the wire rod 2 and pushes the wire rod 2 into the substrate 9 during insertion, and prevents the wire rod 2 from falling out of the V-groove 8 of the pusher 10 during cutting and molding of the wire rod 2, and an inserting guide 13 for forming the wire rod 2 and guiding the wire rod 2 into a predetermined hole 12 of the substrate 9, and an insertion guide 13 for guiding the wire rod 2 into a predetermined hole 12 of the substrate 9. The structure includes an insertion unit 16 having a fixed blade 14 and a movable blade 15 for cutting to a size of .

Problems that the invention sought to solve However, under such a configuration, the fed wire rod 2 is cantilevered by the nozzle 5, so its tip 17 is not regulated in position, and the nozzle 6 is After moving from the position to the forming position, vibrations remain at the tip 17 of the wire. This phenomenon increases as the insertion pitch becomes longer or the wire diameter of the wire rod 2 becomes smaller.
The time for vibration damping to an acceptable level also increases, which has a negative effect on shortening the insertion takt.

In addition, since the wire rod 2 often has some bend left, the tip of the wire rod 2
7 may not be positioned correctly under the V-groove 8 of the pusher 10, which may cause molding defects. This phenomenon also increases as the insertion pitch becomes longer and the diameter of the wire rod 20 becomes smaller.

As described above, during long-pitch insertion or high-speed tact insertion, the material 2 cannot be reliably positioned directly under the V-groove 8 of the pusher 1o, leading to insertion failure due to molding defects and reducing the pushing reliability.

The present invention solves the above-mentioned problems.Even when inserting a long pitch, high tact, and thin wire, the position of the tip of the wire is reliably regulated and formed to ensure insertion reliability. It provides equipment.

Means for Solving the Problems In order to achieve the above object, the present invention provides a supply section that feeds out a predetermined amount of wire, an insertion section that inserts the wire after forming it into a predetermined shape, and a regulation section that regulates the position of the wire. The feeding section includes means for moving the wire in two positions: a feeding position and a forming position, and the tip of the wire is pressed against the regulating part in an elastically abutting state. It is structured as follows.

Operation The present invention secures insertion reliability by reliably regulating and shaping the position of the tip end of the wire even during long-pitch insertion and high-tact insertion with the above-described configuration.

The special molding position 56 of the nozzle 27 is on , the swing center 53 of the nozzle 27 and the pusher 31
Since it is on the line 68 connecting the center of the V-groove 34L on the left side of the figure, the tip of the wire 19 should be moved by x = 3.5 twn more than the V-groove 34R of the pusher 31 on the right side of the figure. And so. However, because of the regulation plate 51, the wire rod 19 is elastically deformed while being pressed against it. Due to this elastic force, the tip of the wire 19 is
Stable positioning is possible at a position directly below the V-groove 34 of No. 1 (see FIG. 4).

Next, the insertion operation will be explained.

The pusher 31 starts moving toward the substrate 32 by the cylinder 36 via the pusher rod 37, and the groove 34 receives the wire 19. The pusher 31 has a V groove 34 and the wire 1
The cylinder 36 continues to move while receiving the molding lever 9, and the movement is stopped by stopping the cylinder 36 intermediately at the point where it comes into contact with the tip of the forming lever 44. At the same time, the cylinder 6o moves the movable blade 48 toward the substrate 32 and intersects the fixed blade 49, thereby cutting the wire 19 into a predetermined size.

Further, the insertion guide 38 is moved toward the substrate 32 by the cylinder 42 via the insertion guide rod 43, and the V groove 4o formed in the insertion guide 38 is controlled by the forming lever 44, and the V groove 4o formed in the insertion guide 38 moves the wire 19 Bending and forming.

The insertion guide 38 continues to move while receiving the bent wire 19 in the V-groove 40, and then stops when its tip abuts against the substrate 32 (see FIG. 6).

Next, the cylinder 46 starts moving the molding lever rod 47 in the direction away from the substrate 32, thereby causing the molding lever 44 to swing in the direction of arrow a. At the same time,
The bushing 31 is moved by the cylinder 36 via the bushing rod 37 toward the substrate 32 while receiving the bent wire 19 in the V-groove 34, and by contacting the substrate 32, the bushing 31 moves the wire 19 to the substrate 32. (see Fig. 7).

Finally, the pusher 31, insertion guide 38, forming lever 44, and movable blade 48 return to their original positions.

During the above insertion operation, immediately after the fixed blade 49 and the movable blade 48 cut the material 19, the nozzle 27 moves to the position 6 at the time of forming.
6 to the supply position 67, the wire rod 19 is fed out by the supply roller 22 by the length necessary for the next insertion, and the wire rod 19 is moved to a standby state.

By repeating such a cycle, the wire can be continuously inserted into the predetermined hole 33 of the substrate 32.
