Description

Technical Field

[0001] The invention belongs to the field of battery manufacturing, and in particular relates to a vibrating negative pressure component. Background Art

[0002] In the existing production process of large cylindrical lithium batteries, a negative pressure formation process is required, that is, the battery is continuously re-discharged and the waste gas generated inside the battery is extracted through a negative pressure nozzle, thereby activating the electrode material and generating a solid electrolyte interface membrane.

[0003] Because there are many batteries on a single tray, the negative pressure equipment also needs a corresponding number of negative pressure caps to guide the batteries. The existing negative pressure caps have the problem of frequent battery jamming due to large friction or viscous residual electrolyte after negative pressure formation. Since manual entry into the equipment is too cumbersome and poses a safety hazard, there is a need to solve the battery jam problem. Summary of the invention

[0004] In view of the above problems, the present invention proposes a vibrating negative pressure assembly. The design concept is to add a vibrator to the negative pressure assembly for extracting exhaust gas from the battery. After the charging and discharging process is completed, the vibrator is started to shake the batteries in the negative pressure caps onto the tray, thereby avoiding the problem of the negative pressure caps getting stuck in the batteries.

[0005] The vibrating negative pressure assembly includes a transverse negative pressure support frame 4, a plurality of negative pressure cups 2 are connected to the lower end of the top frame of the negative pressure support frame 4 in the transverse direction, and a plurality of negative pressure caps 1 are connected to the lower surface of the bottom frame of the negative pressure support frame 4; the positions of the negative pressure cups 2 and the negative pressure caps 1 correspond to each other up and down; the negative pressure caps 1 have a vertical cavity inside, which can accommodate cylindrical batteries in the vertical direction; a plurality of vibrator units 3 are arranged in the transverse direction on the upper edge of the bottom frame of the negative pressure support frame 4; the negative pressure support frame 4 is connected to an external lifting cylinder.

[0006] More specifically, the number of the 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 present invention is as follows: the external lifting cylinder drives the negative pressure support frame 4 to descend, and the cylindrical battery on the battery tray is inserted into the negative pressure cap 1, so that the liquid filling port on the top of the battery contacts the negative pressure cup 2, and then the battery is charged and discharged through the external circuit. At this time, the negative pressure cup 2 extracts exhaust gas from the inside of the battery; after the heavy discharge is completed, the vibrator unit 3 is started to shake the battery still stuck in the negative pressure cap 1 to the battery tray.

[0009] The beneficial effect of the present invention is that the battery is separated from the negative pressure cap by the vibrator unit after the negative pressure formation is completed, thereby avoiding the problem of the battery being stuck in the negative pressure device and reducing the production cost of the battery.
