Semi-Automatic Pouch Cell Winding Machine SAPW-724 ATOMFAIR®

This machine requires a stable single-phase AC220V±10% power supply and a compressed air source of 0.5–0.8 MPa. The winding process demands precise electrode alignment and vacuum-assisted holding to maintain winding precision within ±0.5 mm.

• Electrode Alignment: Manual electrode feeding requires precise alignment with the guide plate to prevent misalignment during winding.
• Vacuum Holding: Vacuum-assisted electrode holding is essential during winding to prevent electrode slippage and maintain uniformity.
• Tension Control: Passive tension control with adjustable tension must be set appropriately to avoid separator stretching or wrinkling.
• Needle Retraction: Trapezoidal interlocking winding needles must retract automatically after winding to avoid damaging the wound cell.

This procedure outlines the steps to set up and operate the semi-automatic winding machine for pouch cell production. It covers power and air connection, parameter setting, and the winding cycle.

Required Equipment: Touch screen PLC control, Vacuum pump, Compressed air supply

1. Connect utilities
   Connect the machine to a single-phase AC220V±10% power supply and a compressed air source of 0.5–0.8 MPa.
2. Set winding parameters
   Set the winding speed, cell dimensions, and other parameters on the touch screen PLC interface.
3. Load separator and electrodes
   Load the separator roll onto the feeding shaft and manually place the sheet electrodes onto the guide plate with vacuum holding engaged.
4. Initiate winding cycle
   Start the automatic winding cycle; the machine will pull the separator, insert the winding needle, and wind the cell.
5. Monitor the winding process
   Monitor the winding process to ensure electrode alignment and tension are maintained; adjust if necessary.
6. Remove the wound cell
   After winding, the needle retracts automatically; remove the wound cell from the winding area.

The Atomfair-SAPW-724 semi-automatic pouch cell winder provides a practical bridge between manual and fully automatic winding, delivering consistent winding precision (≤0.5 mm) and a wide cell size range (30–100 mm length, 30–80 mm width, up to 10 mm thickness) for R&D and pilot-scale production. Its roll-type separator feeding with passive tension control and vacuum-assisted electrode holding supports uniform winding, while the PLC touchscreen enables precise parameter setting and step-back functionality. However, the machine requires a compressed air supply (0.5–0.8 MPa) and manual electrode placement, which limits throughput and introduces operator dependency, and the standard 60 mm winding needle width may not suit all electrode widths without customization.

Positive

• High winding precision and uniformity: Winding precision is ≤0.5 mm, and the combination of passive tension control, vacuum-assisted electrode holding, and trapezoidal interlocking needles ensures consistent, uniform winding—critical for electrode alignment and cell performance in R&D.
• Wide cell size compatibility: Cell width adjusts from 30–80 mm and length from 30–100 mm (max thickness 10 mm), enabling flexible processing of various prismatic/pouch cell formats without dedicated tooling changes.

Trade-offs

• Requires compressed air supply: The machine needs a clean, dry compressed air source at 0.5–0.8 MPa, adding infrastructure and maintenance requirements in the lab or production environment.
• Manual electrode placement limits throughput: Electrodes are loaded manually, which reduces cycle speed and introduces operator-dependent variability, making the machine less suitable for high-volume production despite its semi-automated winding.
