Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a rotor injection molding mechanism and a production line for producing vehicle rotors. Background Art

[0002] As a device that can convert electrical energy into driving torque, the motor is widely used in various fields, including the new energy field and the automotive field. The motor consists of two parts, the rotor and the stator. It is a device used to realize the conversion of electrical energy to mechanical energy and mechanical energy to electrical energy. The rotor is generally formed by embedding a magnetic steel sheet with a certain number of pole pairs on the surface of the iron core or embedded in the iron core. During the process, glue injection molding is required to fix the magnetic steel sheet to the iron core to prevent the magnetic steel sheet from moving or falling off.

[0003] During the production process, after the magnetic steel sheet is inserted into the iron core, the pre-assembled iron core and magnetic steel sheet are sent from the assembly line to the injection molding machine for injection molding. The transfer method is generally clamped by claws. During the clamping process, the magnetic steel sheet is easy to fall off the iron core, resulting in injection molding failure or defective products. Utility Model Content
