PRODUCT PARAMETERS
Description
Automatic Winding Machine for Cylinder & Pouch Cells | 3-Needle Design | ≥10PPM
Product Overview
Our Automatic Winding Machine is a high-speed, precision-engineered solution designed for the automatic winding of digital lithium battery cells. As one of the key pieces of equipment in battery production, it features a three-winding needle and three-station winding design for coordinated operation, fast winding speeds, and extremely low failure rates.
The machine utilizes a servo system with closed-loop tension control for the positive electrode, negative electrode, and separator. This ensures consistent tension coil-by-coil throughout the winding process, effectively preventing deformation of the battery core during downstream processes.
With a precision of ±0.3mm and production efficiency of ≥10PPM, this CE-certified winding machine is ideal for manufacturers producing high-quality cylindrical and pouch cells.
The PLC interface is designed to be humanized and scientific, with clear fault location display for easy troubleshooting and minimal downtime.

How It Works
- Material Loading: Positive electrode, negative electrode, and separator materials are loaded onto the machine’s unwinding shafts.
- Three-Needle Winding: The unique three-winding needle design operates across three stations simultaneously. The coordinated movement ensures continuous, high-speed production with minimal idle time.
- Closed-Loop Tension Control: Servo motors provide real-time, closed-loop control of tension for all three materials (cathode, anode, separator). This ensures tension remains consistent from the first turn to the last, preventing deformation.
- Completed Cell Ejection: Once the programmed number of windings is complete, the finished jelly roll is automatically ejected and transferred to the next process (such as taping or housing insertion).
- Fault Monitoring: The PLC system continuously monitors machine status. If an issue occurs, the fault location is displayed on the HMI for immediate attention.
