The winding apparatus includes a base and at least two winding pins. The base has a winding position and a finishing position, the winding position and the finishing position being each provided with a winding pin, where the winding pin at the winding position is capable of exchanging positions with the winding pin at the finishing position. Each of the winding pins includes a main body portion and a first cutter assembly, where the first cutter assembly includes a first cutter disposed inside the main body portion; and the main body portion is configured to be circumferentially rotatable about an axial direction thereof relative to the first cutter, where an outer periphery of the main body portion is configured as a winding-attaching surface for wind-attaching a material during rotation of the main body portion.
