Automatic Winding Machine For Cylindrical Cell Production

 


1. Device Description

The equipment is used for the production of cylindrical lithium-ion battery cells and is one of the key equipment for battery production. The working process is roughly as follows: after the active unwinding, the positive and negative pole pieces and diaphragms made by the film making mechanism go through tension control, dust removal, process deviation correction, iron removal, diaphragm electrostatic removal, quality monitoring and other operations, and enter the winding part under the guidance of the guide wheel and pole piece guide mechanism. After the winding production is completed, the electric core is removed by the manipulator for short-circuit detection, and is sent to the collection platform by the conveyor belt after photoelectric counting. If nonconforming products are detected during the manufacturing process, they will be removed and entered into the nonconforming product collection box during the transportation process.


2. Incoming Material Requirements

2.1 Positive and Negative Plates
1) Tolerance of Wide Slitting
A: Within 0.1mm

Deviation of Coating Width Direction

Thickness: Within 3%


2) Waveform, Bending, Warping

No waveform (Refers to the defect of the end face);
Warping (After cutting, the pole piece of the cutting part curls);
Serpentine Error: The serpentine error of the length of the pole piece unit is less than 0.3mm/1m.
3) Red or green and other obvious color tapes shall be used for tape connection to facilitate
detection, and a single roll shall be discharged at the winding place.
4) Final Marking: The signal used up as the material of the original reel and the uncoated part

of the terminal are more than 1m.


2.2 Isolating Membrane
1) Slitting Width Tolerance: ± 0.05mm
2) Visual judgment of waveform, bending and skirt shape is excluded.

3) Final Marking: The final mark can be marked in green or black for the signal of exhaustion
