Cylindrical Battery Semi-Automatic Winding Machine

Model: XE-SJR (18650, 21700, 26650 & 32650)

Profile:

Semi-Automatic Winding Machine is mainly used for the precision winding of core of the cylinder battery. This machine can be applied for 18650, 21700, 26650 and 32650 together

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

1. Adopt single needle counterwinding needle structure.
2. Manual lead-in electrode, automatic winding, automatic change needle, automatic tape ending tape and automatic unloading;
3. The adhesive tape adopts the horizontal paste (the tape is perpendicular to the tab), the adhesive is flat, and the adhesive position can be controlled accurately without tightening the cell; the adhesive is stable and reliable;
4. winding needle speed was adjustable;
5. Two rolls of separator active to unwinding, tension push switch control technology can adjust tension automatically during winding.
6. It has a dust removal device;
7. Separator outer pack end.
8. The cell after winding without damage, core pulling and electrode dislocation phenomenon;
9. Easy to operate,adjust and replace;

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.
