The BUSBAR structural stator assembly line is a line with a high degree of automation and guaranteed product quality. It mainly completes the assembly and splicing of the BUSBAR structural stator. It adopts an industrial control acquisition data system to realize the traceability of product production process information. The process flow of this wire : stator core loading → winding, paint removing → piecing together a circle→ laser marking → comprehensive performance test + material collection and other processes.
