This line is a soft pack power battery module assembly PACK line 3D drawing double VDA battery assembly line. The drawings and models of this line total about 2GB, with about ten thousand various parts diagrams. The 3D model of this equipment is designed using SolidWorks 2016 software. The structural parameters of the 3D model drawings are modifiable. This line is mainly developed for soft pack power battery modules and is divided into three major sections: 1. Cell Processing, 2. Module Assembly, 3. Pack Assembly._x000D_
_x000D_
The working principle and process flow of the equipment include:_x000D_
1. Cell Feeding: Automatic cell feeding (manual film peeling), double-sided film peeling of the cell protection film, cell frame supply frequency > 20min, using small AGV carts to feed materials with plastic frames standing upright._x000D_
2. Cell Scanning: Reading cell barcodes, recording in the MES system, reading incoming cell parameters._x000D_
3. Cell Testing: Measuring positive and negative terminal voltage, internal resistance, side voltage, and polarity judgment, recording in the MES system, comparing with incoming cell parameters; automatically rejecting defective products, the system records defective items and can correspond to barcodes._x000D_
4. Tab Trimming: Cutting positive and negative tabs according to processing requirements._x000D_
5. Tab Shaping: Mainly to prevent cell tab deformation._x000D_
6. Cell Unloading: Delivering cells to the module assembly section, 1P/2P cells are respectively conveyed to the dual-channel module assembly section, including defective product discharge stations; defective tests do not proceed with trimming._x000D_
7. Support Plate Feeding (Brackets): 1P/2P support plate feeding, support plate material cart magazine feeding, material frequency > 20min._x000D_
8. Module Assembly: 1P sequence: Cell-Support Plate, 2P sequence: Cell-Support Plate-Cell._x000D_

Cell Stacking: Assemble and stack small module cells; stack modules according to requirements, differentiate positive and negative terminals, features flip and rotate functionality, assembly methods: 1P12S/2P6S/3P4S/4P3S; stacking methods: 1P*12/(1P+2P)*4/(1P+2P+1P)*3; cushioning foam is provided between cells; special attention to positive and negative terminal differentiation and insulation protection._x000D_
14. Metal Frame Assembly Welding: Install and laser weld module bases and protection plates; 4000W continuous laser welding, can appropriately increase weld scar count for improved reliability, penetration depth > 1.2mm (vertical peel force > 300N)._x000D_
15. Busbar Copper Bar Connection._x000D_
16. Module Inspection Offline._x000D_
The entire line includes all processes and equipment structures to achieve various functions in soft pack VDA battery assembly. The process and structural design for power batteries are excellent, especially the end cap laser welding and cell transfer structures. The dual channel at the front end of the device effectively improves the efficiency of the entire line. The compatibility of feeding various components with AGV cart feeding is quite prestigious due to the extensive drawing content; detailed structures and specifics require downloading the drawings for further understanding.
