Abstract
A non-stop constant-speed efficient winding machine for separator relates to the technical field of lithium ion cell manufacturing. The non-stop constant-speed efficient winding machine for separator includes a base plate, an electrode feeding mechanism, a winding mechanism, a separator cutting mechanism, and a separator compounding mechanism. The winding mechanism includes a winding head and three winding needles rotatably provided on the winding head. By additionally providing the separator compounding mechanism between the electrode feeding mechanism and the winding mechanism, thermal compounding of the separator is realized, and through rolling separator cutting of the separator cutting mechanism, the separator cutting is realized. The winding needle located at the winding position can adsorb a separator end after the cutting, and wind the separator end on an outer circumferential surface of the corresponding winding needle.
