Semi-Auto Winding Machine for Lithium-Ion Cylindrical Cells

 


I. Equipment Function Description

This machine is primarily designed for precision winding of cylindrical lithium-ion battery cells.  
Process flow: The operator manually loads the positive and negative electrode sheets into the winding area. These sheets are interleaved with separators and wound in accordance with process specifications. Subsequently, the machine automatically applies termination tape and ejects the wound cell in an automated manner.

 

II. Equipment Functions & Features

1. Single-needle through-shaft winding structure.

2. Manual electrode loading → automatic winding → automatic needle change → automatic termination-tape application → automatic discharge.

3. Termination tape applied horizontally (perpendicular to electrode tabs); flat, accurately positioned, does not tension the cell; stable and reliable.

4. Winding-needle speed adjustable.

5. Dual separator rolls with active unwinding; proximity-switch tension control enables smooth automatic adjustment; upper & lower tension adjustable.

6. Separator wrap-out finish.

7. Finished cells are free of damage, core-pulling, or electrode misalignment.

8. Easy operation; quick specification changeover.

 

III. Process Flow

The machine meets cylindrical-cell winding standards (separator fully wraps anode; anode wraps cathode).

1. Separator pre-winding — toothed-blade method saves separator length.

2. Feed anode manually → Feed cathode manually.

3. Winding.

4. Work-position transfer.5. Separator cutting → termination-tape application → cell discharge.

IV. Main Assembly

· The machine consists of winding units, positiontransfer unit, separatorunwinding units, electrodeguide units, automatic feeding units, tapeapplication unit, discharge unit, and control system.

· Winding units (2 sets): singlehead throughshaft design ensures precision; needles can be replaced easily.

· Positiontransfer unit (1 set): switches between winding station and taping station.

· Separatorunwinding units (2 sets): active unwinding with pneumatic tension control.

· Electrodeguide units (2 sets): singleside adjustable, easy finetuning.

· Tapeapplication & discharge unit (1 set).

· Automatic feeding units (2 sets):

· Operator places sheets on the feed plate; cylinders position them.

· A cylinder pushes the sheet along a guide rail to the winding point.

· During winding, cylinders press the electrodes to ensure uniform pressure.

· Cylinder feeding guarantees identical sheet position and pressure, ensuring consistent tab location, thickness, and sheet length (assuming material consistency).
