Abstract

This research is on the design and performance test for decreasing defect rate and improving the production speed of stacking machines used to build secondary battery electrodes. The key parameter that affects production speed and defect rate is the electrode film feeding system. There are two feeding system methods: gripper and belt. We chose the belt feeding method for the low-noise and high-speed production. However, the belt feeding method has a slip problem, which lowers production speed and increases the defect rate on the electrode film. Therefore, we designed a slipless belt feeding system to reduce slip. Removing slip to ensure accurate position leads to increased production speed, uniform size of electrodes, and lower defect rate. We designed the system and then manufactured to test target performance. The feed rate, cutting position accuracy, and zigzag displacement of the electrode were tested and evaluated.
