Abstract: The present application discloses a winding shaft fixture, a winding device, and a method for preparing an electrode assembly. The winding shaft fixture includes a clamping mechanism and a tensioning mechanism. The clamping mechanism is used to clamp or release an end of a winding shaft. The tensioning mechanism is connected to the clamping mechanism, and the tensioning mechanism is configured to apply a pulling force to the clamping mechanism when the clamping mechanism clamps the end of the winding shaft, so as to apply the pulling force to the winding shaft. According to the technical solutions of the present application, the winding shaft can be allowed to have a higher winding speed to improve the production efficiency of the electrode assembly.
