Semi-automatic Winding Machine for Supercapacitor Manufacturing

 Products Description 

The XW-15060YZ Battery Winding Machine is a semi-automatic device designed for precision winding of cylindrical lithium batteries. Its operational workflow consists of the following steps: operators manually feed the cathode and anode electrodes into the winding section, where they are properly separated by the separator. The machine then performs the winding process according to specified technical parameters, automatically applies termination tape, and finally ejects the completed battery cell automatically.

Device function and features

1. Adopt single needle structure

2. Artificial feeding electrode, automatic winding, automatic needle change, automatic termination of adhesive tape and automatic blanking.

3. Adopt horizontal way to stick tape(Termination of the tape is perpendicular to the tab), tape stick flat, tape stick location can be precisely controlled and will not tighten batteries core; tape stick is stable and reliable.

4. Jelly roll winding speed adjustable

5. Two rolls of separator take the initiative to unwind, tension close-spaced switch control technology, tension can be automatically and smoothly adjusted during winding process.

6. With electrode dust removal system；

7. Separator epiboly wind up；

8. Winding finished of core without damaged, loose core and electrode dislocation phenomenon.

Easy to operate, adjust and replace the specifications simple and fast.

Technological process

The device meets the cylindrical lithium-ion battery winding technology standards: the separator is fully wrapped negative electrode, negative electrode wrapped positive electrode.

The technological process is as follows：

1. Separator preroll：Tooth cutter technology can save preroll separator length；

2. Cathode：artificial feed the positive electrode into the winding department；

Anode：artificial feed the negative electrode into the winding department；

3. Winding；

4. Changing station；

5. Separator cut off, stick termination of tape and blanking.
