Model: MR-SJR (18650, 21700, 26650 & 32650)
Profile:
Working Process
Manually guide the cathode and anode electrodes into the winding part, and separated stacking with the separator, and the winding will be carried out according to the requirements of the process, automatically attaching the termination tape, and the cell will automatically feed.
Function and Features
Technological Process:
The equipment meets the winding process standard of cylindrical lithium-ion battery: the diaphragm completely wraps the negative sheet, and the negative sheet wraps the positive sheet. The process flow is as follows:
1) Diaphragm pre coiling: Adopting tooth cutter technology can save the length of pre coiling diaphragm;
2) Draw in the negative electrode: Manually guide the negative electrode sheet into the winding part; Draw in the positive electrode: Manually guide the positive pole piece into the winding part;
3) Winding;
4) Shift station;
5) Cut off the diaphragm, paste the termination glue and blanking.
