Description

Description: TECHNICAL FIELD The present invention relates to a jumper wire insertion device for inserting a wire into a predetermined position.

2. Description of the Related Art Conventionally, this type of jumper wire insertion device has a configuration as shown in FIG. In FIG. 7, in a feeding section, a wire 2 supplied from a reel 1 is supplied to a strainer section 3.
And a pair of feed rollers 4 (the front side is not shown)
The feed roller 4 is held by a motor 5
It can be driven via a coupling 6, a shaft 7, and a gear 8, and the feed amount of the wire 2 is adjusted by a motor 5.
Further, the wire 2 is provided with a nozzle 9 provided at the position of the sending section.
The position is regulated by inserting. The insertion portion has a V-groove 10 (FIG. 8) for receiving the wire 2 in order to regulate the direction perpendicular to the axis of the sent wire 2 and pushes the wire 2 into the printed circuit board 25 during insertion. A pair of pushers 11 and V-grooves of the pushers 11 when cutting and forming the wire 2
A pair of swingable forming levers 12 for preventing the wire 2 from falling off from 10 and restricting the wire 2 in a direction perpendicular to the axis, and enabling shaping of a predetermined shape; A pusher 11 and an insertion guide 13 are provided with a pair of insertion guides 13 for guiding the wire 2 into predetermined holes of the printed circuit board 25, a fixed blade 14 and a movable blade 15 for cutting the sent wire 2 into predetermined dimensions. And the molding lever 12 are connected to the coupling 17, the shaft 18, the belt 1 by the motor 16 only when the insertion pitch is switched.
9, the pulleys 20 and 21, the ball screw 22, the block 23 and the bracket 24 can move in the pitch direction in conjunction with each other.

However, in such a configuration, the movement of the pusher, the insertion unit, and the forming lever is performed only when the insertion pitch is switched, and the supply-side and insertion-side motors 5, 16 are separately provided. When the wire rod 2 is driven, if the feed amount of the wire rod 2 is large or the wire diameter is small, as shown in FIG. The V-groove 10 of the pusher 11 cannot reliably control the position of the wire 2, which results in poor insertion due to poor molding, which significantly reduces the operation rate of the apparatus. Further, even if the position of the wire 2 is regulated by enlarging the V-groove 10 of the pusher 11, the dead space due to the pusher 11 at the time of insertion is increased, and there is a problem that it cannot be applied to high-density insertion. .

In view of the above problems, the present invention ensures reliable molding by preventing run-out of the wire tip even when the wire feed amount is large or the wire diameter is small, thereby ensuring the reliability of insertion and improving the productivity. It is an object of the present invention to provide a jumper wire insertion device capable of improving the performance.

The movable blade cuts the wire fed from the feed unit with a fixed blade, regulates the wire in a direction perpendicular to the axis, forms the wire into a predetermined shape, and can be inserted into a predetermined position of the substrate. In the jumper wire insertion device including the insertion unit, when feeding the wire rod by the feed unit, the movable guide block is brought closer to the fixed guide block. The wire rod is controlled based on a command from a setting device for setting the dimensions of the wire rod to be inserted, and the wire rod is fed out until it reaches the standby movable lever and the movable guide. After that, a control device for synchronizing the movement of the wire rod and the movement of the movable side guide block to move the wire rod to a predetermined position is provided.

In the initial state, the wire 31 supplied from the reel 32 is in a state in which the strain in the direction perpendicular to the axis is removed by the strainer portion 33, and the tip of the wire 31 is fixed as shown in FIG. The guide block 66 moves toward the fixed guide block 65 at the position of the movable blade 53 and the movable blade 54, and the forming lever 50 is at the position closest to the forming lever 49.
Next, the motor 36 is controlled and rotated until the feed amount set in the setting device 101 is reached by the control device 102, and the rotation is transmitted to the shaft 38 via the coupling 37,
The rotation is also transmitted to the shaft 39 via the gears 40, 41, and the feed rollers 34, attached to the respective shafts 38, 39,
35 rotate in opposite directions to each other. Then, as shown in FIG. 5 (b), when the wire 31 is fed by a predetermined amount until it is supported by the forming lever 50 and reaches below the movable guide 55, the control device 102 turns the motor 56 on. The ball screw 62 is rotated through the coupling 57, the shaft 58, the belt 59, and the pulleys 60 and 61 in synchronization with the rotation of the ball screw 62.

The motor 36 in the feed unit 30 and the insertion unit 44
The conditions for synchronizing with the motor 56 are when the wire is fed over a predetermined length or when the wire diameter of the wire is smaller than a predetermined value.In a normal state, the insertion speed is increased and the productivity is improved. For this purpose, the motor 36 may be driven to supply the wire rod, and the motor 56 may be driven to switch the insertion pitch.

As described above, according to the present embodiment, the forming lever and the insertion guide pusher can be moved in synchronization with the wire supply of the feed unit 1 so that the wire feed amount is large or the wire diameter is small. In this case, reliable insertion of the wire by more reliable molding becomes possible, and productivity can be improved.

As described above, according to the present invention, a means for synchronizing the motor for driving the feed roller of the feed unit and the motor for driving one movable forming lever, insertion guide, and pusher of the insertion unit is provided. Therefore, even when the feed amount of the wire is large or the wire diameter is small, the wire can be moved stably by the forming lever regardless of the bending of the wire tip and the deflection due to the device vibration. This makes it possible to insert the mold securely and improve the machine operation rate and productivity.

In addition, the above configuration uses a mechanism that can variably set the insertion pitch and does not require a completely new mechanism,
It can be realized at low cost.
