In the spot welding production process of solar cell panels silver foil electrodes and wires, manual methods have always been mainly relied on to align welding gun electrodes and solder joints. Due to factors such as the large welding work area (more than 3.5m× 2m), the small size of the wires to be welded, and the strong background reflection of the silver foil electrode, the alignment of the solder joints is very inconvenient, which seriously affects the welding production efficiency and welding quality., which in turn becomes a safety hazard for whether solar panels can work reliably for a long time in an unmanned environment. The successful development of this technology has solved the above problems well.

 The solar cell automated welding technology guidance automation system based on visual guidance uses image recognition methods instead of manual identification of weld points, and uses motion control technology and human-computer interaction technology to guide the welding gun to reach the weld points to improve production efficiency and ensure welding quality. It greatly simplifies the solder joint alignment work during resistance spot welding of solar panels, improves the welding production efficiency while ensuring that the alignment accuracy meets production requirements, and also greatly reduces the labor intensity of welding workers. This system has great practical application value for improving the automation level of solar panel resistance spot welding systems.

 This system has great practical application value for improving the automation level of resistance spot welding of solar panels. It can be applied to resistance spot welding of large solar cells for aerospace use. After transformation, it can be applied to the automated welding field of other types of solar cells, as well as automated fields that require precise positioning and movement control.
