### Comprehensive Process Overview for Battery Pack Storage Assembly

This article provides a detailed breakdown of the battery pack storage assembly process, focusing on each critical step to ensure efficient production and quality control.

#### 1. Loading with Six-Axis Robots

The process begins with loading components onto the assembly line using six-axis robots. These robots handle precise placement of parts, ensuring consistency and accuracy in the initial stage of assembly.

#### 2. OCV Testing

Once loaded, the Open Circuit Voltage (OCV) of the battery cells is tested. This step is crucial for verifying the initial voltage and ensuring that each cell meets the required specifications before proceeding further.

#### 3. Plasma Cleaning and Foam Padding

The battery cells undergo plasma cleaning to remove contaminants and improve adhesion. Following cleaning, foam padding is applied to protect the cells and enhance the overall durability of the battery pack.

#### 4. Manual End Plate Adhesive Application and Loading

End plates are manually fitted with adhesive and loaded into the assembly system. This step is performed with precision to ensure proper adhesion and alignment.

#### 5. Automated Stacking by Robots

Robots then automatically stack the components, arranging them in the correct configuration. This automated stacking enhances efficiency and reduces manual handling.

#### 6. Module Automatic Clamping and Unloading

The assembled modules are clamped automatically by robots to ensure secure positioning. After clamping, the modules are unloaded from the assembly line, ready for the next stage.

#### 7. Side Plate Adhesive Application and Loading

Side plates are equipped with adhesive and loaded onto the assembly line. This step involves applying glue to ensure a strong bond between the plates and the battery cells.

#### 8. End Plate Robot Welding

Robots perform welding on the end plates, joining them to the battery cells. This automated welding ensures precise and consistent welds, crucial for the structural integrity of the battery pack.

#### 9. Post-Welding Inspection

After welding, the battery packs undergo a post-welding inspection. This step verifies the quality of the welds and checks for any defects or inconsistencies.

#### 10. Insulation Resistance Testing

Insulation resistance testing is conducted to ensure that the battery pack’s insulation meets safety standards and prevents electrical leaks.

#### 11. Laser Cleaning of Pole Columns

Pole columns are cleaned using a laser to remove any residues and ensure proper contact for the next assembly stages.

#### 12. Manual Busbar and Busbar Welding

Busbars are manually installed and welded onto the battery pack. This step requires careful handling to ensure secure connections and optimal performance.

#### 13. 6KW Laser Welding

A 6KW laser welding system is used for precise and high-quality welding of critical components. This advanced welding technology ensures strong and reliable joints.

#### 14. Post-Weld CCD Inspection

After laser welding, the battery packs undergo a CCD inspection to detect any defects or issues in the welds, ensuring high-quality standards are met.

#### 15. Manual Visual Inspection and Cleaning

A final manual visual inspection is performed to check for any visible defects or contaminants. The battery packs are cleaned if necessary to maintain quality.

#### 16. End-of-Line (EOL) Testing

End-of-Line testing is conducted to evaluate the overall performance and functionality of the battery packs. This comprehensive testing ensures that each pack meets the required specifications.

#### 17. DC Internal Resistance (DCIR) Testing

DC Internal Resistance testing is performed to measure the internal resistance of the battery cells. This step is essential for assessing the efficiency and performance of the battery pack.

#### 18. Module Unloading

Finally, the completed battery packs are unloaded from the assembly line. They are now ready for packaging and distribution.

Note: These processes can be customized according to customer requirements.

This detailed process ensures that each battery pack is assembled with precision, quality, and reliability, meeting the highest standards for storage battery packs.
