Electrode burrs refer to the stretching and bending of the substrate surface caused by electrode punching. Controlling the size of burrs during punching, reducing dust generated during punching, and avoiding burr generation during electrode transfer have become the main challenges facing these two processes. To solve these problems, it is necessary to first understand the causes of burr and dust generation.
There are three main reasons for the generation of electrode burr dust: 1) the punching method; 2) the structure of the punching die; and 3) the material and processing precision of the punching die.
Based on the causes of burrs and dust generation, future solutions can be improved in the following aspects:
1. Optimize the existing mold structure;
2. Improve the precision of mold manufacturing and assembly;
3. Select a laser die-cutting machine;
4. The die-cutting and stacking machine is adopted. After the electrode is punched, it can directly enter the stacking platform, avoiding collision and friction between the electrode and the material box, and completely solving the potential risk of electrode defects.
