[0002] Collector rings are also called conductive rings, slip rings, collector rings, and collector rings. They can be used in any electromechanical system that requires continuous rotation while transmitting power and signals from a fixed position to a rotating position. Slip rings can improve system performance, simplify system structure, and prevent wires from being twisted during rotation.

Moreover, the copper busbar is generally bent by manual control during the process of turning around. However, the bending force and angle cannot be accurately controlled during manual operation, which is easy to affect the subsequent use of the conductive ring and cause waste of materials.
