The invention provides a battery shell welding leakage test system, which enables a set of helium detection instrument to test products in a plurality of sets of test jigs respectively, the utilization rate of the helium detection instrument is high, and the cost is reduced. And the sealing pressure is controlled and monitored by the side plug structure, so that the damage to the product caused by overlarge pressure is effectively avoided, and the yield of the product is ensured. The battery case welding leakage test system is characterized by comprising an installation seat, a plurality of detection stations, a plurality of detection terminals, a plurality of detection terminals and a plurality of detection terminals, the portal frame comprises a cross beam, and the cross beam is located over a straight line formed by arranging the detection stations; and a plurality of groups of detection station device assemblies, wherein each detection station device assembly comprises a jig base, a test jig, a pressing mechanism and a side sealing mechanism. A corresponding detection station device assembly is assembled on each detection station; the jig base comprises a base fixing block, a base, a cavity valve terminal, a product valve terminal and a helium detection control valve.
Description
technical field [0001] The invention relates to the technical field of leakage testing, in particular to a battery shell welding leakage testing system. Background technique [0002] After the existing battery shell is welded, it is necessary to carry out the leakage welding test. The existing operation process is: manually put the product into the test fixture, and test the product with the equipment. The equipment has one or two stations, and the product is tested by the cylinder. seal. The utilization rate of its helium detection instrument is low, the cylinder sealing pressure is difficult to control, and the product is deformed after overpressure, causing the product to be scrapped, and the equipment testing time is long, the efficiency is low, the cost is high, and the product scrapping rate is too high. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides a battery shell welding leak test system, which enables a set of hel...
