[0002] As a special type of motor, the chain motor has unique features in the design and structure of the stator core. The stator core of the chain motor is usually composed of a series of ring-shaped or chain-shaped cores, which are precisely connected together to form a closed ring structure. The main function of this structure is to provide a magnetic circuit and fix the stator coil to ensure the efficient and stable operation of the motor. Each core maintains a high degree of consistency in shape and size to ensure the overall performance and quality of the motor.

[0003] In the current production process, after the core is inserted into the chain plate fixture, the whole forms a chain plate fixture assembly. Then, operations such as winding copper wire, circular welding, wire arranging, wire shearing, paint stripping, crimping electrical terminals, and hanging copper wire on the terminals need to be carried out on the product. After the above processes, wire clamping and wire shearing are also required. Currently, both wire clamping and wire shearing rely on manual operation.
