Description

technical field [0001] The invention belongs to the technical field of gas discharge tube production, in particular to an automatic welding device for spot welding of gas discharge tubes. Background technique [0002] The production of gas discharge tubes mainly includes the steps of mounting, sealing and welding. Among them, the welding is to attach one end of the two sets of electrode wires to the conductive areas on both sides of the porcelain tube, and then use two sets of spot welding heads to simultaneously weld the contact points on both sides. [0003] With the development of science and technology, the current gas discharge tube production line is becoming more and more automated, especially the welding process. The transmission device directly transmits the porcelain tube and two sets of electrode wires to the spot welding head, and the induction module of the spot welding head After the ceramic tube and electrode wire are sensed, welding will start automatically....

AI Technical Summary

Problems solved by technology

[0004] However, during the welding process of the traditional automatic welding device, the porcelain tube and the electrode wire are static, and the welding head can only weld the contact surface of the porcelain tube and the electrode wire from one direction, which leads to uneven welding points and different contact surfaces. The welding effect of the direction is also good or bad.
