Formula can not all eliminate the variation of influence and volume of the air pressure to flexible package shape.Such as: flexible package test inflation or exhaust process
In, due to the variation of external pressure, the volume of flexible package can change, if also, product have leakage, volume and pressure in packaging
It will change, therefore no matter all not used using pressure detection or volume detection；
2, halogen detection method, VOC detection: by determining whether to let out to volatilization gas, liquid specific molecular and elemental analysis
Dew, this method can not be to carbon-based element molecule and not volatile Molecular Detection.
Utility model content
In order to make up for the defects of the prior art, the utility model provides a kind of flexible-packed battery leak test method and machines
Structure.
The utility model is achieved by the following technical solution:
A kind of flexible-packed battery leak test mechanism, including insulation upper cavity, insulation lower chamber and voltage measuring apparatus, institute
It states in insulation upper cavity and insulation lower chamber and is respectively equipped with conductive sponge, insulate and be equipped with conduction between upper cavity and insulation lower chamber

Further, the insulation upper cavity is equipped with pressure breathing mouth.
Further, the conductive sponge on the insulation upper cavity is connect by the first extraction wire with voltage measuring apparatus.
Further, the conducting block is located on insulation lower chamber, is located at the intracorporal conductive sponge of insulation cavity of resorption and conducting block
Contact, conducting block are connect by the second extraction wire with voltage measuring apparatus.
Further, sealing ring is equipped between the insulation upper cavity and insulation lower chamber.
The beneficial effects of the utility model are: 1) detection efficiency is high: leakage initial stage can detect, without waiting；
2) pollution-free: leakage initial stage detects and stops, and not will cause the external many battery fluids of leakage；
3) solve the problems, such as that current flexible-packed battery industry can not hunt leak after packaging.
Detailed description of the invention
