WINDING DEVICE AND METHOD FOR WINDING MATERIALS

Embodiments of the present application relate to the field of battery manufacturing technologies, and particularly to a winding device and a material winding method; the winding device is configured to wind a material and includes: a winding switching mechanism, a compounding mechanism and a breaking mechanism, wherein the winding switching mechanism includes a rotating disc and a plurality of winding pins arranged on the rotating disc at intervals, and the material is wound around one winding pin along a preset path; the compounding mechanism is provided upstream of the winding pin along the preset path and configured to laminate and then compound the plural layers of materials at a preset position; the breaking mechanism is provided between the compounding mechanism and any winding pin along the preset path and configured to break the compounded plural layers of materials at a compounding region. The adoption of the winding device and the material winding method according to the embodiments of the present application can prevent the plural layers of materials from being layered at the breakage moment and after breakage, thereby avoiding or alleviating misalignment between the plural layers of materials.
