Description

[0001] technical field [0002] The invention relates to the field of robot spot welding automation technology, in particular to a car body robot automatic welding system. Background technique [0003] With the application of the spot welding process in the automobile manufacturing industry, spot welding is now the main connection process method for automobile bodies and other components, and it plays an irreplaceable important role in the automobile manufacturing industry. The quality problems of spot welding are becoming more and more serious. In the car body manufacturing process, the quality of the welded joints not only directly determines the manufacturing deviation of the car body welding assembly process, but also determines the reliability and safety of the car. Generally speaking, the car body About 4000-6000 spot welds are needed, so the connection quality of the spot welding of the car body determines the overall structural rigidity and integrity of the car. ...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the car body welding is still done by manual operation. There are working conditions such as harsh environment, high labor intensity, and unstable product quality. If the problem is not discovered until it is assembled on the assembly line, repair welding, leak repair, correction, and deformation are required, which will affect the progress of the assembly line, and then affect the economic benefits and core competitiveness of the enterprise. Therefore, eliminating welding defects is of great significance to automobile assembly. Based on this, it is still necessary to design an automatic welding system for car body robots.
