Wire welding machine

Abstract

The invention discloses a wire welding machine which comprises a wire welding workbench, a wire tying head above the workbench, a part requiring wire welding and fixed at the lower end of the wire tying head, an optical part disposed above the wire tying head, a control, parallel flat cables connected with the control system and the part requiring wire welding, and a tightening mechanism. By the tightening mechanism, the parallel cables can be tightened during rotation of the wire tying head, no redundant parallel cables are generated, and accordingly rotation of the wire tying head and the part requiring wire welding cannot be affected, and the problem that the interference winding occurs between the parallel cables or the part requiring wire welding, the wire welding effect is affected, and overall stability of equipment is affected is solved.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a wire bonding machine. Background technique [0002] In the design process of the wire bonding machine, since the axis of the wire binding head perpendicular to the working platform needs to be set as an optical path channel, the parallel wiring at the wire binding head cannot communicate with the control system along the optical path channel of the wire binding head axis, so the parallel arrangement One end of the wire needs to be connected to the interface on the signal acquisition board of the wire binding head, and the other end is directly connected to the control system set in the wire bonding machine. However, due to its own gravity, the parallel cable is easy to sag, which will affect the operation of other components. normal work. [0003] In order to ensure that the parallel cable does not sag, the parallel cable is usually wound on the binding head, and th...

Problems solved by technology

However, since the wire bonding machine is in the process of bonding wires, the wire binding head must be continuously rotated to an appropriate angle to ensure that the wire welding process can proceed smoothly, so the parallel cable length between the wire binding head and the control system is constantly occurring. This creates a problem: if the length of the parallel cable arrangement required when the thread-binding head rotates in the maximum forward direction is taken as the length of the parallel cable arrangement, then when the thread-binding head rotates in reverse to the maximum angle, the thread-binding head and the control system The length of the parallel cables between them will far exceed the length of the above-mentioned parallel cables, then those redundant parallel cables will cause the signal lines of the part of the binding head to be irregular or chaotic, resulting in the parallel wiring at the binding head. At the same time, it is easy to interfere with rotating parts such as wire binding head or welding parts, which will affect the effect of welding wire and the overall stability of the equipment
