Brief introduction of important processing flow of power lithium battery pack

The processing process from a simple battery cell to a lithium battery pack is also quite complicated, requiring multiple processes, which is not simpler than the manufacturing process of the battery cell. 1. Load the battery cells to the designated position, and the robot will automatically grab and send them to the module assembly line. 2. Give the cells a bath. The plasma cleaning process cleans the surface of each cell. Ion cleaning is used here to ensure that pollutants in the process do not adhere to the bottom of the cell. 3. Assemble the battery cells. Glue the battery cells. Before assembling the battery, apply glue on the surface. In addition to fixing purposes, the application of glue can also serve the purpose of insulation and heat dissipation. High-precision gluing equipment and manipulators can cooperate with each other to apply glue on a set trajectory, while monitoring the glue quality in real time to ensure the glue quality and further improve the consistency of each group of different battery modules. 4. Build a home-end and side-plate welding power lithium battery module for the battery cell. Most of the power lithium battery modules are welded with aluminum end-plates and side-plates, and the lamination and end-plate and side-plate welding are performed by robots. 5. After the wire harness isolation board assembly welding monitoring system accurately locates the welding position, bind the wire harness isolation board material bar code to the MES processing scheduling management system, and generate a separate code for traceability. After coding, the wiring harness isolation board is automatically installed into the module by the manipulator. 6. Complete the series and parallel laser welding of the battery through automatic laser welding, complete the connection of the pole and the connecting piece, and realize the series and parallel connection of the battery.
