Fully Auto Winding Machine For Cylindrical Cell Production

 Products Description 

This winding machine is used for the production of cylindrical lithium-ion battery cells and is one of the key equipment for battery production. The general working process is as follows: after active unwinding, the positive and negative pole pieces and diaphragms made by the film-making mechanism undergo tension control, dust removal, process correction, iron removal, diaphragm static removal, quality monitoring and other operations, and enter the winding section under the guidance of the guide wheel and the pole piece guide mechanism. After the winding production is completed, the battery cell is taken out by the robot for short-circuit detection, and is sent to the collection platform by the conveyor belt after photoelectric counting. If defective products are found during the production process,

 Technical Parameters 

Material requirements:

1. Positive and negative: Width slitting tolerance: within 0.1 mm.
2. Coating width deviation: Thickness: within 3%.
3. Waveform, bending, warping:
   1. No waveform (referring to end surface defects);
   2. Warping (after cutting, the cut part of the pole piece curls);
   3. Serpentine error: the serpentine error of the pole piece unit length is less than 0.3mm/1m.
4. Tape connection should use red or green tape with obvious colors to facilitate detection, and discharge a single roll at the reel.
5. Final mark: used as a signal for the original coil and the uncoated part of the material
   The length of the terminal exceeds 1m.
