AI Technical Summary
In the traditional lithium battery electrode winding process, the tension control system relies on a single sensor, which is susceptible to electromagnetic interference and mechanical vibration, resulting in large detection errors and a high risk of single-point failure. It cannot distinguish between tension-related fluctuations and non-tension-related anomalies, leading to electrode wrinkles and quality problems.
A multi-sensor fusion system is adopted, including a tension monitoring module, a displacement monitoring module, and a visual monitoring module. Data fusion is used to improve monitoring accuracy and control precision, and to distinguish between tension-related fluctuations and non-tension-related anomalies.
This improves the tension control accuracy and system reliability during the lithium battery electrode winding process, reduces electrode wrinkles and positional misalignment, and ensures battery quality and lifespan.
