Introduction: The detection accuracy of helium mass spectrometer leak detection is high and can reach 1×10-7Pa•m3/s. Before the battery is inspected, the air in the battery is removed first, and then helium gas is injected into the battery to detect whether there is leakage of helium gas using a helium-mass spectrometer leak detector to determine whether the airtightness of the battery is intact. The battery inspection is generally in two ways: one is in the middle of the battery production, that is, before the battery is dried and injected, the battery is leaked. The battery is filled with helium in the vacuum box and tested. This method can detect the battery cover. Whether the gas-tightness of the cover welding and the battery shell is up to standard; the other is leak detection in the finished product, the battery is filled outside the box, the battery is filled with the electrolyte and the hernia is filled into the battery. Inside, then place the battery in a vacuum box for leak detection. Technical performance: 1. The vacuum box size is determined according to the size of the battery core; 2. It is generally a three-box linkage system, and the production cycle can meet a single 6PPM-12PPM; 3. Open the door, can be designed according to the user's production process requirements, generally flat-open door type, slide-box type; 4. Manipulators or robots are used for loading and unloading, and no manual operation is required during normal production; 5. The system is equipped with two-dimensional code scanning device, which can store the detection data of each cell correspondingly; 6. Clear function 7. Has helium recovery function (this function is optional) 8. Automatic judgment and corresponding placement (that is, unqualified products placed on the unqualified line, qualified products placed on the qualified line) 9. Different passwords can be set through the touch screen to change the device parameters; 10. Man-machine interaction interface, touch screen to reflect the running status and test data in real time; 11. Failure statistics function 12. The system adopts high-end configuration and standardized design to ensure stable operation and reliable performance.
