During the welding process, the ultrasonic vibration is generated by the wire bonding machine and transmitted to the splitter. The aluminum wire is stuck in the wedge groove of the splitter. The aluminum wire is welded at the bonding interface of the chip through ultrasonic vibration. Under the action of the welding head, the aluminum wire is pulled to the pin position through the wire guide to complete the welding of the second point, and then moves back to the excess of the cutter to cut the aluminum wire, complete the cutting of the aluminum wire, and finally turn to the welding of the next wire. Therefore, the wire guide will be used in the ultrasonic vibration wedge welding process of aluminum wire.
[0003] The existing wire guide used in the ultrasonic vibration wedge welding process of aluminum wire cannot adjust the distance between the two conveying rollers during use, so that it cannot meet the needs of conveying aluminum wires of different diameters, which in turn leads to a narrow range of use. Secondly, the use height of the device body cannot be adjusted, thereby failing to meet the requirements of different aluminum wire heights.
