Document Type and Number:
WIPO Patent Application WO/2023/155332
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of electrode assembly winding, and in particular to a winding device and a winding method. The device comprises: a winding needle used for winding a coiled material, the winding needle comprising a magnetic portion, and the magnetic portion being disposed in the axis direction of the winding needle; and a magnetic supply assembly used for providing a magnetic field, the magnetic supply assembly being disposed correspondingly to the magnetic portion, and the magnetic field interacting with the magnetic portion to generate magnetic force so as to resist deformation of the winding needle. By means of the winding device, the deformation of the winding needle is reduced, and the risk that an electrode assembly is dislocated or wrinkled in a winding process is reduced.
