Design of arc welding robot workstation with dual station detection based on vision

At present, commonly used arc welding robot workstations mainly include three working surfaces: loading, welding, and unloading during welding operations. The process flow is as follows: the handling robot clamps the weldment for loading, the fixture fixes the weldment, the arc welding robot welds the weldment, and the handling robot clamps the weldment for unloading. The quality of weld seam is mainly determined by the precision of equipment such as positioner, fixtures, and arc welding robot. The welding quality of the weld seam is determined by the pass rate of the sampling samples. This testing method cannot obtain the true product pass rate, nor can it timely remove unqualified products for necessary repairs. Based on this situation, we have designed a arc welding robot workstation with dual station detection based on vision in this paper, which solves the problems of weld seam tracking and post weld seam quality inspection, synchronization of welding robots and handling robots, and welding and inspection of all welds in the flat welding position, achieving the effect of improving quality and efficiency.
