Cylindrical Electrode Forming and Winding Integrated Machine

Cylindrical Electrode Forming and Winding Integrated Machine

This machine unwinds rolled positive and negative electrode sheets and separators via an unwinding device. After tension control, adhesive application, and alignment, the electrode sheets and separators are sequentially wound onto a winding needle according to set process requirements, forming a cylindrical battery cell. Simultaneously, during or after winding, operations such as tab treatment and termination tape application are performed. The main structural components include: unwinding, electrode forming and adhesive application, tension control, alignment, electrode insertion, winding, adhesive application, unloading, and unloading conveyor.

Industry Challenges

Alt Center Distance:
A tab alignment error greater than ±0.5mm results in battery cell failure.

Tension Control:
Tension fluctuations exceeding ±5% can easily deform the battery cell.

Winding Alignment:
A winding alignment error exceeding ±0.2mm can easily cause short circuits in the battery cell, leading to failure.
