Abstract

The embodiments of this application provide a winding pin, a winding apparatus, a battery manufacturing device, and a winding method. The winding apparatus includes a winding pin, a pair of first clamp pins, and at least one second clamp pin. The pair of first clamp pins are configured to move away from each other after the winding pin is withdrawn from an electrode assembly to stretch the electrode assembly, and the second clamp pin is configured to support an upper half portion of the electrode assembly in a process of stretching the electrode assembly by the pair of first clamp pins. The winding pin includes a winding pin body, an outer peripheral surface of the winding pin body is provided with a pair of first grooves, the first groove is configured to accommodate the first clamp pin, the pair of first grooves are spaced apart along a circumferential direction of the winding pin body, and the outer peripheral surface of the winding pin body is further provided with at least one second groove, the second groove is configured to accommodate the second clamp pin, and the second groove is spaced apart from the first grooves along the circumferential direction of the winding pin body. The technical solutions provided in this application can improve the reliability of the battery.
