This equipment is composed of a three-axis module, a linkage shaft, a circuit breaker base mobile carrier plate, a torsion spring mechanism, a return conveying line, a moving and static contact carrier lifting and positioning mechanism, and a moving and static contact handling mechanism. Among them, the moving and static contact carrier incoming materials: conveyed by the conveying line of the previous unit to the moving and static contact carrier lifting positioning mechanism, and the lifting positioning cylinder moves the moving and static contact carrier too high away from the belt line, and is positioned at the moving and static contact carrier. On the lifting positioning mechanism of the contact carrier, the material is to be picked up by the conveying mechanism. The moving and static contact carrier reflow is when the 6 groups of moving and static contact components on the moving and static contact carrier are removed, the moving and static contact carrier lifting positioning mechanism is lowered, and the moving and static contact carrier is put back to the previous unit On the conveying line, the conveying line will send it to the return conveying line 1. After the return conveying line is in place, the carrier of the moving and static contacts is separated from the conveying line of the previous unit while the return conveying line is lifted.
