Instructions for Operating Procedures for the Negative Pressure Vacuum System
1. Begin by inserting the battery into the self-clamping tray; next, align the battery injection port in the prescribed uniform direction, and it is ready for testing.
2. With the battery inserted into the equipment, switch on the driving cylinder switch. The cylinder drives the probe fixture assembly and vacuum suction cup assembly to operate an up and downward gripping action of the battery, while the battery's injection port connects in gapless and seamless docking with the vacuum suction cup.
3. Upon completion of the clamping and docking of the battery probe fixture and docking of the vacuum suction cup with the injection port, switch on the vacuum regulating valve; set the vacuum valve to -90kps; or the process setting value can steplessly set the negative pressure value operating in the STEPS range of -100Kpa to 0Kpa throughout the negative pressure process. The vacuum gauge value should be checked within the prescribed time (if the gauge does not read -90kps, please check if there was an air leakage at the connection of the battery injection port to the vacuum suction cup or other attachment). A pressure gauge is bypassed in the pipeline of the negative pressure unit to read the pressure value, and it is installed in an area that is easy to readily view.
4. When confirming the airtightness is qualified, start the formation charging step process and the negative pressure vacuum system process.
5. In the instance the process ends formation charging, or the equipment has a problem under an alarm, you would first close the vacuum valve to release the vacuum state, then unload the battery or other necessary steps to address the alarm issue.
6. At the conclusion of the formation charging period, you would close the vacuum regulating valve, next, close the pneumatic switch of the fixture, and next, remove the battery tray to complete the formation process.
7. With long-term use of the equipment, please check on a regular basis if there is a crystallization phenomenon in the vacuum suction cup and vacuum pipeline. If there is a crystallization phenomenon, please clean or replace any necessary parts to avoid air leakage.
8. Vacuuming speed ≥50KPa/min; vacuum break speed ≥20KPa/s; leakage rate ≤1KPa/min (after pumping negative pressure and stabilizing pressure).
