Description

Technical Field

[0002] In traditional processing, coil processing is generally achieved by manual winding. However, manual winding is not only slow, but also leads to high labor intensity and labor costs for workers.

Not only can it still not solve the problems of low production efficiency and low capacity, it also leads to high purchase costs for enterprises, which does not meet the requirements of large-scale batch production of enterprises.
