Semi-Automatic Winding Machine for Battery Electrode Assembly
1. Equipment Description:
This machine is mainly used for precision winding of cylindrical lithium-ion battery cells.
Working process: Manually feed cathode and anode sheets into the winding section, interleave them with the separator, wind according to process requirements, automatically attach termination tape, and automatically discharge the finished cell.
2. Equipment Functions and Features
*Adopts a single-needle through-shaft winding structure.
*Operational process: Manual electrode feeding, by automatic winding, needle replacement, tape application, and discharging.
*Utilizes a lateral taping method (with termination tape applied perpendicular to the tabs), ensuring flat, precisely positioned tape application without over-tightening the cell, and delivering reliable, stable performance.
*Winding speed is adjustable.
*Equipped with two active separator rolls, featuring proximity switch-controlled tension; enables smooth automatic adjustment during winding, with support for both upper and lower tension adjustments.
*The separator is wrapped externally at the end of the process.
*Wound cells are free from damage, core displacement, or electrode misalignment.
*Offers easy operation and rapid specification switching.
3. Process Flow
The equipment meets the cylindrical lithium-ion battery winding standard: separator fully wraps the anode, anode wraps the cathode.
Process flow:
1. Separator pre-winding: Uses toothed blade to reduce separator length and avoid thread-pulling and cell bulge.
2. Feed anode: Manually feed into winding unit.
3. Feed cathode: Manually feed into winding unit.
4. Winding.
5. Transfer to taping station.
