What Is a Cylindrical Battery Winding Machine?
A cylindrical battery winding machine winds electrode sheets and separator into a tight, cylindrical jelly roll – the core of 18650, 21700, and 4680 lithium‑ion cells. Winding quality directly affects cell internal resistance, capacity, and safety. Our semi‑automatic model offers the precision of automated winding while keeping capital costs lower than fully automated lines – perfect for entry‑level production or flexible manufacturing.
Semi‑automatic Cylindrical Battery Winding Machine – Key Features
This semi‑automatic cylindrical battery winding machine includes:
Manual electrode reel loading – Operator loads anode and cathode reels manually.
Automatic winding cycle – One‑button start: tension control, separator insertion, electrode winding, and automatic tape termination.
Adjustable tension control – Closed‑loop feedback ensures consistent winding without stretching or wrinkling.
CCD alignment (optional) – Real‑time edge detection for electrode placement accuracy ≤±0.3mm.
Cycle time – Approximately 6‑10 seconds per cell (operator‑dependent).
Tooling changeover – Quick‑change mandrels and guides for different cell sizes (18650, 21700, 4680).
The semi‑automatic design reduces operator fatigue while maintaining high winding consistency.
