[0039] As shown in Figure 1 , Figure 2 , specifically, the winding mechanism includes a telescopic cylinder 1, a winding assembly 2, a rotating assembly 3, etc. The telescopic cylinder 1 can be provided as an electric cylinder and is installed on the mounting frame. The winding assembly 2 is arranged at the telescopic end of the telescopic cylinder 1, i.e. below the telescopic cylinder 1, and the rotating assembly 3 is arranged below the winding assembly 2. Therefore, under the condition that the telescopic cylinder 1 works, the winding assembly 2 can be controlled to descend, thereby contacting the rotating assembly 3, and the end of the wire can be stably placed relative to the winding assembly 2 and the rotating assembly 3. Under the action of the rotating assembly 3, the winding assembly 2 can be controlled to rotate, and at the same time, the winding assembly 2 can adjust its own state to realize the relative lifting movement of the wire and the winding assembly 2, so that the wire is neatly wound.

[0040] The above-mentioned winding mechanism is installed on the existing winding equipment, i.e. replaces the winding mechanism and lifting assembly of the original winding equipment, and the contact surface of the winding assembly 2 and the rotating assembly 3 faces the wire feeding pipe 12 of the winding equipment, and is connected to the control system of the winding equipment, so as to work with the original traction mechanism, wire cutting assembly, moving mechanism and film wrapping mechanism of the winding equipment to realize the neat winding of the wire. Since the winding equipment is an existing patent technology, the traction mechanism, wire cutting assembly, moving mechanism and film wrapping mechanism will not be introduced here. For details, please refer to the patent disclosed in CN111470129A.

[0044] As shown in Figure 2 , Figure 3 , Figure 4 , in order to realize the winding of the electric wire, the winding assembly 2 comprises a top disc 21 and a plurality of spliced plates 24.
