1. The importance of debugging the liquid injection machine

The liquid injection machine is an important equipment in the manufacturing process of lithium batteries, and the accuracy of its debugging directly affects the performance and safety of the battery.

Through debugging, it can be ensured that the various parameters of the infusion machine are set reasonably, ensuring the stability and consistency of the infusion process, thereby improving the quality and production efficiency of the battery.

2. Operation process

a. Equipment inspection: Conduct a comprehensive inspection of the battery electrolyte filling machine, including electrical systems, pneumatic systems, pipeline connections, etc., to ensure that the equipment is in good condition.

b. Parameter setting: According to the production process requirements, set the various parameters of the injection machine, such as injection volume, injection speed, pressure, etc.

c. Debugging and operation: Start the liquid injection machine under no-load conditions, check whether the equipment runs smoothly and whether all functions are normal. Then conduct a load test to observe whether the

equipment can operate normally according to the set parameters.

d. Production verification: Select a small amount of batteries for liquid injection testing to verify the consistency of liquid injection effect and battery performance.

e. Optimization and adjustment: Based on the production verification results, fine tune the parameters of the injection machine to achieve the best effect.

3. Parameter settings

a. Injection volume: Set an appropriate injection volume based on the battery model and capacity requirements to ensure battery performance and safety.

b. Liquid injection speed: Reasonably set the liquid injection speed to ensure uniform internal structure of the battery and avoid problems caused by too fast or too slow liquid injection.

c. Temperature: Set an appropriate temperature according to the production process requirements to ensure the stability of lithium battery materials and injection media.

4. Precautions

1. Safe operation: During the debugging process, safety operating procedures should be to ensure personnel safety and equipment stability.

2. Parameter monitoring: closely monitor the changes in various parameters of the injection machine, and promptly handle any abnormalities found.

3. Cleaning and maintenance: Keep the infusion machine and its surrounding environment clean, and regularly maintain the equipment.

4. Recording and reporting: Detailed recording of the debugging process, timely reporting of abnormal situations for traceability and analysis of problems.

5. Common problems and solutions

a. Inaccurate liquid injection volume: It may be caused by sensor failure or pipeline blockage. Sensors and pipeline connections should be checked to ensure their normal operation.

b. Unstable liquid injection speed: It may be caused by pressure fluctuations in the pump or pipeline. The pump and piping system should be checked to ensure stable pressure.

c. Uneven internal structure of the battery: It may be caused by improper parameter settings of the injection machine or unreasonable pipeline layout. Parameter settings and pipeline layout should be optimized to improve the uniformity of the liquid injection process.

d. High equipment failure rate: may be caused by improper equipment maintenance or harsh usage environments. We should strengthen equipment maintenance and improve the operating environment of the equipment.

6. Summary

The debugging of the injection machine for lithium battery manufacturing process is a key link to ensure battery performance and production efficiency. In practical operation, it is necessary to follow the operating procedures and precautions, set various parameters reasonably, and solve common problems in a timely manner to ensure the quality of the battery and the stability of production. By continuously optimizing the debugging process and improving operational level, we aim to enhance the competitiveness and market share of lithium batteries, and contribute to the development of new energy vehicles and mobile devices.
