In FIG. 1, 101 is a setting device that sets the dimensions of the wire rod 31 to be inserted, and 102 is a setting device that adjusts the motor 36 based on commands from the setting device 101 to control the feeding amount of the wire 31 to the set amount. This is a control device that controls the motor 56 to be driven in synchronization with the motor 36 after a predetermined amount of wire feeding operation.

Next, the operation of the above configuration will be explained.

First, in the initial state, the wire 3 supplied from the reel 32
1 is in a state where the straightness in the direction perpendicular to the axis has been removed by the strainer part 33, and its tip is as shown in Fig. 5 (a).
), the fixed blade 53 and the movable blade 54 are located at the same position, and the guide block 66 is located at the fixed side guide block 6.
5 side, the molding lever 50 is at the position closest to the molding lever 49. The 0th order motor 36 is the control device! 1
02, the rotation is controlled until the feed amount set in the setting device 101 is reached, and the rotation is transmitted to the shaft 38 via the coupling 37, and the gear 40.41
Rotation is also transmitted via shafts 39 to feed rollers 34.39 attached to respective shafts 38.39.
35 rotate in opposite directions to each other. Then, the tip of the wire 31 is attached to the forming lever 5 as shown in FIG. 5(b).
0 and is fed out by a predetermined amount until it reaches the lower part of the movable guide 55, the control device 102 controls the motor 56.
are rotated in synchronization with the motor 36, and the couplings 57,
The ball screw 62 is rotated via the shaft 58, belt 59, and pulleys 60, 61. Then carrier 63
is regulated by the slide shaft 71 and moves in the axial direction of the wire rod 31. With this movement of carrier 63,
The bracket 64 and the guide block 66 move in the direction of the arrow, so that the pusher 48 and the insertion guide 5
2. The movable guide 55 and molding lever 50 are shown in FIG.
As shown in C), it moves in synchronization with the movement of the wire rod 31. Then, when the wire rod 31 moves by an arbitrary feed amount setting, the wire rod 31, the pusher 48, the insertion kite 52, the movable guide 55, and the forming lever 50 stop at the same time.

Next, the insertion operation will be explained. The pushers 47 and 48 are regulated by the shaft 70 due to the lowering of the block 69.
begins to descend, and the grooves 45 formed in the pushers 47 and 48 receive the wire 31. Upon receiving the wire 31, the pusher 47.48 abuts the forming lever 49.50;
As shown in FIG. 6(a), the movement is restrained. At the same time, as the block 67 descends, the insertion guide 51.52 regulated by the shaft 68 descends, and the movable blade 54, which descends in conjunction with this insertion guide 51.52,
By intersecting the blade 3, the wire 31 is cut into a predetermined size. Further, as the insertion guide 51.52 is lowered, the groove 77 formed at the tip of the insertion guide 51.52 regulates the wire 31, and as shown in FIG. 6(b), the forming lever 49.50 The wire rod 31 is bent and formed. The insertion guides 51 and 52 are bent wire rods 3.
1 is received in the groove 77, and as shown in FIG. 6 fc), the tip comes into contact with the printed circuit board 46 and stops.

At this time, due to the lowering of the guide plate 76 supported by the guide blocks 65 and 66, the forming levers 49 and 50 are moved through the roller 72 link 73 and the pin 74 to the state shown by the two-dot chain line in FIG. The wire rod 31
to open. Then, the downward restraint of the pushers 47 and 48 is released, and the pushers 47 and 48 descend, pushing down the bent wire 31 while receiving it in the V-shape 45.
By coming into contact with the printed circuit board 46, as shown in FIG.
As shown in FIG. 3, the wire 31 is inserted into the printed circuit board 46. The inserted wire 31 is processed to prevent extraction by a lower die (not shown).

Note that the conditions for synchronizing the motor 36 in the feeding unit 30 and the motor 56 in the insertion unit 44 are when the wire is fed beyond a predetermined length or when the wire diameter of the wire is thinner than a predetermined value. In this case, in order to increase the insertion speed and improve productivity, the motor 36 may be driven to supply the wire, and the motor 56 may be driven to change the insertion pitch.

As described above, according to this embodiment, the forming lever and the insertion guide pusher can be moved in synchronization with respect to the feeding of the wire rod by the feeding unit 1. In this case, it is possible to insert the wire more reliably by forming the wire rod more reliably, thereby improving productivity.

Effects of the Invention As described above, according to the present invention, a means is provided for synchronizing the motor that drives the feed roller of the feed unit and the motor that drives one of the movable molding levers, the insertion kite, and the pusher of the insertion unit. As a result, even when the wire rod feed rate is large or the wire diameter is small, the wire rod can be moved stably by the forming lever, regardless of bending of the wire tip or vibration due to equipment vibration.
More reliable molding enables reliable insertion, improving machine operating rates and productivity.
