The movement of the movable blade 37 is performed in conjunction with the insertion guide 27 by a ball 4o that is attached to be movable in the two axial directions of the wire inside the wire groove 39 formed in the insertion guide 27 and the movable blade 37. With a slight movement after crossing, the protrusion 41 of the movable blade 37 comes into contact with the fixed blade 38, and the ball 40 moves because the fixed blade 3B has a line groove 42 that can be removed from the line groove 39 of the insertion guide 27. stops. Further, after the same state, the protrusion 41 of the movable blade 3a is separated from the insertion guide 27. The slider 43 and the stopper 44 are located on the wire rod 2 supply direction side of the insertion guide 27, and have a structure in which the movable blade 37 and the fixed blade 38 are removed, and the movement of the slider 43 is controlled by the stopper 44. A slope 46 is formed on the slider 43 to move the guide 11 in the wire rod 2 supply direction by an amount that releases the wire rod 2 from being received by the guide 11 when the guide 11 is stopped. The cylinder E33 that drives the slide cam 34 is the cylinder E33 that drives the slide cam 34.
4 swings the lever 31 and comes into contact with the bushing rod 21 at the moment when the pusher 24 is released.

The pusher 24 comes into contact with the printed circuit board 17 in a state in which the cylinder E33 has moved furthest toward the printed circuit board 17 side.

The operation of the electronic component insertion device configured as described above will be explained below. First, the original state of each part of the device will be explained. The wire rod 2 supplied in a reel is a strainer 3, a pair of chuck claws A4, a pair of chuck claws BT, and a nozzle 1.
0 and its tip is received in the hole of the guide 11. A pair of chuck claws A4 are driven by a cylinder A6 and clamp the wire 2. The pair of chuck claws BT release the wire rod 2 from being clamped. The guide 11 is close to the nozzle 1o. Further, the piston rod 14 is located at the farthest position from the printed circuit board 17.

Next, feeding of the wire rod 2 will be explained. At the same time as the pair of chuck claws B7 clamp the wire 2 by the cylinder B8, the pair of chuck claws 4 release the wire 2 from being clamped by the cylinder A5. Next, as the pair of chuck claws BT are moved by the cylinder C9, the guide 11 attached to the arm 12 is also moved, and the wire 2 is fed out with its tip received by the guide 11 while its curls are corrected by the strainer 3. .

Next, the insertion operation will be explained. At the same time as the piston rod 14 starts to move toward the printed circuit board 17 side due to the compressed air flowing in from the air hole 19, the bushing rod 21 also moves in the same direction due to the bias of the spring 22, and the bushing rod 24
A V-groove 26 formed in the shape receives the wire 2. When the pusher 24 receives the wire 2, it comes into contact with the tip 36 of the lever 31 and its movement is stopped, and at the same time the insertion guide 27
The wire rod 2 is cut into a predetermined size by the movable blade 37 moving in conjunction with the blades of the fixed blade 3B intersecting with each other. Also, at the same time as the wire rod 2 is cut, the slider 43 moves the guide 11
is moved in the two axial directions of the wire rod 2 to release the reception of the wire rod 2.

Further movement of the piston rod 14 allows the V-groove 3o formed at the tip 29 of the insertion guide 27 to restrict the wire 2 while bending the wire 2 with the lever 31. The insertion guide 27 moves while receiving the bent wire 2 and the V groove 28, and stops when the tip 29 comes into contact with the printed circuit board 17. Next, the cylinder 1C33 is activated, and the slide cam 34 swings the lever 31 in the direction of arrow B via the roller 35, thereby releasing the restriction on the movement of the cylinder 24. At the same time, the bushing rod 21 and the cylinder 1
33 comes into contact. The pusher 24 moves the bent wire 2 into the V groove 2 by the action of the spring 22 and the cylinder E33.
6, move the wire 2 to the printed circuit board 17 side and contact the printed circuit board 17, so that the wire 2 is attached to the printed circuit board 1.
Insert into 7. The inserted wire rod 2 is processed to prevent extraction by a lower die (not shown).

Finally, the origin return operation will be explained. When the cylinder E33 moves away from the printed circuit board 17, the piston rod 14 also moves in the same direction due to the inflow of compressed air from the air hole B20.

As a result, the insertion guide 27 and the pusher 24 move in the same direction and return to the original position. After the movement of the cylinder E33 and the piston rod 14 is completed, the clamping of the wire 2 by the pair of chuck claws BT is released, and at the same time, the clamping of the material 2 by the pair of chuck claws 4 is performed. Thereafter, the guide 11 moves in the same direction via the arm 12 interlocked with the pair of chuck claws BT by operating the cylinder C9, and approaches the nozzle 10. At this point, cylinder C9 also stops operating.

By repeating the above cycle, the wire rods 2 can be continuously inserted into the predetermined holes 26 of the printed circuit board 17.

Effects of the Invention As described above, the present invention provides a feeding unit that feeds a wire rod by an arbitrarily set amount in the axial direction, a guide that regulates the position of the wire rod in a direction perpendicular to the feeding direction, and a feed unit that feeds the wire rod by an arbitrarily set amount in the axial direction. By removing the restriction on the position of the wire and providing an insertion unit that forms the wire into a predetermined shape and inserts it into the predetermined position, the wire rod tip can be prevented from warping even when the wire feed rate is large and the wire diameter is small. By doing so, molding can be performed reliably and insertion reliability can be ensured.
