In this automation system, three KUKA robots cooperate with the end pickup to carry the sheet metal parts and carry out spot welding. One robot (R0) is arranged at the head of the assembly line for feeding; Two robots (R1 and R2) are arranged at the tail of the assembly line, equipped with two spot welding and end pickup for spot welding, blanking and stacking.

Advantage：
①The feeding robot can grasp one type of plates, or alternatively grasp two different types of plates, and automatically detect the types to realize mixed material production, so as to solve the pain point that the left and right parts of the door panel can not be produced in a complete set of automation.
②At the blanking end, two robots weld different positions at the same time to improve the beat and production efficiency. The beat of the whole line is 23S / piece.
③AGVs can automatically connect the plate silo at the feeding end and the spraying line at the blanking end.
