Program Overview

Gas-tight inspection machine is an essential inspection process in the production of lithium-ion batteries, which is used for testing the sealing of the top cover of power batteries after welding.
After the battery top cover is welded and evacuated, a certain pressure of helium gas is flushed into it, and a vacuum space with a certain degree of vacuum is outside the tested battery, which is connected to the leakage port of the helium detector. If there is a leak in the tested product, the helium gas leaking into the vacuum space can be measured by the helium detector, and the leak means the product is not sealed properly.
