AI Technical Summary
Existing negative pressure caps are prone to causing frequent battery jamming after negative pressure formation due to high friction or viscous residual electrolyte, resulting in cumbersome manual operation and potential safety hazards.
A vibratory negative pressure assembly was designed. By adding a vibrator unit to the negative pressure support frame, the vibrator is activated after the negative pressure formation is completed to shake the battery down to the tray, thus preventing the negative pressure cap from jamming the battery.
This effectively avoids the problem of batteries getting stuck in negative pressure equipment, thus reducing battery production costs.

[0006] More specifically, the number of vibrator units 3 on the negative pressure support frame 4 is three.
[0007] More specifically, the vibration mode of the vibrator unit 3 is up and down vibration.
[0008] The working process of the utility model is as follows: the external lifting cylinder drives the negative pressure support frame 4 to descend, the cylindrical battery on the battery tray is clamped into the negative pressure cap 1, the liquid injection port at the top of the battery is in contact with the negative pressure cup 2, then the battery is charged and discharged through an external circuit, at this time, the negative pressure cup 2 extracts the waste gas from the inside of the battery; after the recharging is finished, the vibrator unit 3 is started to shake the battery still clamped in the negative pressure cap 1 to the battery tray.
[0009] The utility model discloses beneficial effect lies in: the battery is separated from the negative pressure cover cap after the negative pressure formation ends through vibrator unit, avoid the problem of negative pressure equipment card battery, reduce the production cost of battery.
