Description

Multi-axis spot welder structure improvement

This creation is about a spot welder, especially a multi-axis spot welder.

According to the application principle of the automatic spot welding machine, the metal objects are mainly melted and joined by positive and negative electrodes. Up to now, the automatic spot welding machine used in the industry is still in a semi-automatic stage, the main reason is The displacement of the spot welding object and the positioning of the spot welding position are still controlled manually, which causes the manual control of the object displacement and the visual spot welding position. It is difficult to achieve the goal of precise spot welding. The finished spot welding object is also difficult to meet the quality standard, and the production speed is slow. The spot welding machine is only a single-arm type and is equipped with a single-axis positive electrode holder, and can only perform a single-point spot welding state, so that the spot welding object not only needs to perform the X-axis pushing displacement, but also needs to perform Y again. The lateral displacement of the shaft can be applied to the same row of welding operations, making the overall operation complicated and inconvenient, not only greatly increasing the operating cost, but also lacking the working efficiency, which is actually the missing of the conventional spot welding machine.
