It buttresses, hand is revolved in rotation right arm (3), blocks battery with locating slot, adjusts good position, and battery cephalosome exposes, screws rotation hand, then revolve
Turn forearm (4) rotation hand, sealing ring (44) allowed to hold out against battery tail portion, into the water by battery and device, opens high pressure gas valve,
Air pressure is adjusted to designated value, battery cephalosome state is observed, is completed.
Due to the market demand of high-energy density to be adapted to, pier envelope technique, neck are finally mostly used when cylindrical battery seals
It almost no longer interspaces at pilot trench, it is fixed can not block as before when sealing sealing and security test notch at neck
Position.The device of the utility model can efficiently solve problem above, make the leakproofness and safety of high-energy density cylindrical battery
Valve security test is easy to operate, simple and effective.
