Abstract

PURPOSE:To prevent stress from applying to a wire more than required by maintaining a constant linear relation between the drawing out direction of a wire from a wire spool and the position of a bonding head. CONSTITUTION:A wire spool 3 is mounted to a shaft of a rotary motor 4. The rotary motor 4 is threaded with a screw 5 and mounted with a nut 7. The wire spool 3 moves in both directions with the nut 7 by turning the screw 5 mounted to the shaft of a transfer motor 6. This construction makes it possible to keep the constant linear relation between the drawing out direction of a wire 2 and a bonding head 1 by moving the wire spool 3 in conformity with the movement of the bonding head 1.

The wire 2 was automatically fed to the bonding head 1 by rotating the motor 6. That is, the bonding head 1 was provided with the horn 1b to which the capillary 1a was attached, and the wire 2 was supplied from the wire spool 3 to the capillary 1a via the wire shake prevention ring 1d and the clamper 1c.

題点があった。In this conventional wire automatic feeding device, since the motor for feeding the wire is fixed, the bonding head is largely moved left and right in parallel with the X-axis direction to perform bonding. As shown in FIG. 2, since the wire extending direction is not in a linear relationship with the bonding head when viewed from the front, extra stress is applied to the wire, which causes bending of the bonding wire.

FIG. 1A is a front view and FIG. 1B is a side view. The wire spool 3 is attached to the shaft of the rotation motor 4, the motor 4 is attached to the nut 7, and the screw 5 is rotated by rotating the movement motor 6.
The wire spool 3 moves left and right in parallel with the X-axis direction of the bonding head together with the nut 7. The position information of the bonding head 1 moving left and right for the bonding operation is fed back to the motor 6 to rotate the screw 5 and move the wire spool 3 so that the wire 2 is always fed out and the bonding head is moved as shown in FIG. You can make it look like a straight line when viewed from the front.
