The invention discloses a residual power line winding device for screw rod sliding block type stator assembly production. The residual power line winding device for screw rod sliding block type statorassembly production comprises a base, a stable base, a first drive motor, a winding reel, a leading ring and a second drive motor. The stable base is arranged on the lower ends of support rods; the winding reel is rotatably installed between an output shaft of the first drive motor and a connecting shaft through a coupler; and the leading ring is further welded to the upper side of an upper slidesleeve. During winding, the leading ring moves left and right so as to play a role in guiding a power line, so that the occurrence of a twisting phenomenon can be effectively avoided; meanwhile, thepower line can be uniformly wound on the winding reel so as to be prevented from being fully wound at a certain position on the winding reel; and compared with manual winding, the winding speed is faster, the working efficiency is greatly improved, a product takt is accelerated, and the replacement speed is improved.
