Two-station Lithium Cylindrical Cell Battery Cap Pressure Tester and Air Tightness Testing Machine
It is mainly composed of two sets of cylinder-driven testing fixture components, single-stage gas booster pump, digital pressure transmitter, high-pressure solenoid valve, PLC touch screen and other control electrical appliances, computer and supporting test data acquisition system.
One is to conduct random inspection of the outage pressure and bursting pressure of the incoming materials of the cap, and the other is to check the empty shell lithium battery, samples are randomly inspected for outage pressure value, burst pressure value and sealing air tightness. The empty shell lithium battery used for sampling refers to the finished product of the normally produced non-filled lithium battery, or the sample specially used for testing without battery cells. It is necessary to drill a small hole in the center of the bottom of the negative electrode of the empty shell lithium battery, and at the same time, ensure that the negative electrode of the cap is connected to the shell to perform the test. Through a special fixture component, the air tightness of the lithium battery is detected by visual inspection.
