Cell Pilot Winder - CPW
The Digatron Systems CPW is designed to support the production of cylindrical cells, including 18650, 21700, 26650 and 46XX formats. It comes equipped to handle one cell size, with additional tooling sets available for other sizes upon request.
Our CPW winds jelly rolls for cylindrical cells, handling from unwinding electrodes and separators, cutting and welding tabs (optional), to winding the roll and securing it with tape before ejecting the finished cell.
The machine unwinds the rolls of electrodes and separators, cuts, and welds tabs onto both the anode and cathode electrodes. The electrodes and separators are aligned using dedicated edge position control systems, with their tension programmable for optimal performance. The machine precisely feeds the electrodes onto the winding mandrel and proceeds to wind the jelly roll, securing it with tape. Once the winding is complete, the finished cell is automatically ejected from the mandrel into a buffer container.
This efficient and fully automated process ensures high precision and consistency in cell manufacturing, significantly reducing the need for manual intervention and increasing overall productivity.
