This machine is mainly applicable to the winding of cylindrical lithium-ion battery cells.

1) Artificial monolithic upper electrode piece, automatic winding, automatic change of winding needle, automatic sticking termination tape and cutting, automatic unloading 

2) Separator continuous, separator tension can be adjusted according to need, tension adjustment range: 0.1N-10N, and keep constant.

3) The tension of the electrode piece can be controlled during the winding process.

4) The width of the electrode piece trough can be adjusted to fit different types of electrode pieces widths, with high dimensional accuracy and wear-resisting, smooth surface.

5) This equipment adopts transverse sticking, the length and width of sticking can be adjusted greatly, it is very easy to ensure the appearance and size quality of the electric core.

6) The coil needle made of high-strength materials can be smoothly pulled out without affecting the neatness of the already rolled core, nor will it scratch the separator or cause the core to become spiral shaped

7) Roll needle diameter range: ¢2.5 --- ¢8.0, suitable for winding various specifications and models of cylindrical lithium-ion batteries such as 14500, 14430, 18650, 2665032650, etc

8) separator continuous feeding, PLC and precision potentiometer constant tension control, pressure sensor detection, the electric core winding process is uniform force.

9) Utilization rate： ≥98%

10) The yield rate of the wound battery core can reach 98%, and the error of electrode ear center distance: ≤ ± 0.5mm
