In the intricate process of battery manufacturing, mechanical notching plays a crucial role. This step involves shaping the metal foil of electrodes and tabs through cutting or stamping. However, it produces a significant amount of leftover material. To efficiently manage this byproduct, Villo has developed a specialized scrap compressor machine, ensuring the perfect collection and compression of scrap generated during notching.
Once notched, the electrode sheets are conveyed to the stacking machine, where a repeated Z-folding process stacks positive and negative electrode sheets together with a separator to assemble a bare cell. Although minimal dust is generated during this stage, controlling it is essential. Villo's advanced dust collector system provides the necessary suction force, preventing the sheets from shifting during transportation. Additionally, dust removal is implemented either at the suction inlet of the stacking machine or via a side suction hood at the stacking location, maintaining a clean and efficient manufacturing environment.
