Abstract

The embodiment of the invention provides a wire welding machine. The wire welding machine comprises an axial driving device, a welding head, a rotation driving device, a flexible transmission device and a connecting device. The welding head is connected with the axial driving device; the flexible transmission device is connected with the rotation driving device; the connecting device is fixedly connected with the welding head and the flexible transmission device; the rotation driving device drives the flexible transmission device to rotate, and the axial driving device drives the flexible transmission device to carry out telescopic movement when driving the welding head to move in the axial direction of the welding head. In this way, loads can be prevented from increasing when the wire welding machine moves axially, and the wire welding precision of the welding head is improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a wire welding machine. Background technique [0002] Wire bonding machines include gold wire machines, aluminum wire machines, ultrasonic wire bonding machines, etc. The wire bonding machine is mainly used in high-power devices: light-emitting diodes, laser tubes, small and medium-sized power triodes, integrated circuits and inner lead welding of some special semiconductor devices. [0003] During the wire welding process, the wire bonding machine needs to continuously adjust the direction of the wire, that is, the welding head needs to be rotated to ensure the smooth progress of the wire welding process. In the prior art, the welding head rotation is realized by the drive device transmitting torque through a rigid shaft. However, this way of transmitting torque makes the distance between the driving device and the welding head relatively fixed. When the welding head needs to ...
