CENO produced electric power slip ring is also often used in lithium battery winding machines.
Lithium battery winding machine is used to wind lithium battery cells. It is a machine that assembles the positive electrode sheet, negative electrode sheet and separator of the battery into a core pack (JRlellyRolI) in a continuous rotating manner.
①Pre-winding: The initial feeding process of the negative electrode sheet. In this process, the positive and negative electrode sheets are clamped by the electrode sheet feeding mechanism and sent to the winding needle at a certain speed. It is necessary to control the rotation angle and speed of the winding needle and the electrode sheet feeding mechanism. match. This process involves two synchronizations: the unwinding speed of the diaphragm is synchronized with the needle winding speed, and the pole piece feeding speed is synchronized with the needle winding speed.
②Winding process: After the initial feeding process of the positive and negative electrodes is completed, the negative electrode is tightly wrapped by the separator and wound around the winding needle, and the continuous winding can be realized by turning the winding needle subsequently. In this process, the unwinding speed of the pole piece unwinding motor is adjusted by detecting the tension of the reel to ensure the constant tension of the reel during the winding process.
In the more than 50 processes of lithium battery production, the cooperation of high-speed rotating conductive slip rings is indispensable. CENO hollow shaft series slip rings can be customized slip rings for lithium battery equipment. At present, several series of slip rings have been used in many lithium batteries production equipment.
