Description
Technical field
The present invention relates to a kind of lithium battery froth in vacuum device.
Background technology
Lithium battery, especially cylindrical lithium battery, it also remains some gas by after battery core drying, sabot, fluid injection in battery core
Bubble needs to remove bubble (subsequent processing repeatedly by way of vacuumizing in the glove box of froth in vacuum device：Sealing).Hand
In casing, to prevent electrolyte moisture absorption from air, it is also necessary to the gas in vacuum glove box is kept relatively low by dehumidifier
Humidity, lithium battery is carried out by adsorption box after once adsorbing, it is necessary to by injecting N2 (nitrogen) in adsorption box to balance
Pressure in adsorption box, it is convenient to unpack.In this course, it is necessary to using substantial amounts of N2, with the 18650 of an annual output 100000
Exemplified by type cylindrical lithium battery, it needs to use 30 bottles of N2 (40L, 12.5MPa) daily, its is of high cost up to more than 40 ten thousand.Therefore, it is necessary to
A kind of new froth in vacuum device carries out de-bubble processing to lithium battery, to cancel N2 uses.
The content of the invention
The technical problems to be solved by the invention are to provide for a kind of defoaming device without using nitrogen, realize above-mentioned purpose
Technical solution it is as follows：
Lithium battery froth in vacuum device, including glove box, placement tray in glove box, places battery core on pallet, battery core
Installation driving device nearby, the driving device connect adsorption box, and driving device drives adsorption box lifting, while adsorption box connects
Vacuum extractor, wherein, adsorption box can fasten or separate with pallet, and adsorption box absorbs the bubble in battery core, and is stored in
In adsorption box, after adsorption box and pallet fastening, the vacuum extractor extracts the dry gas in adsorption box, the glove box
Interior installation booster pump, the booster pump are connected with adsorption box, after vacuum extractor extracts the dry gas in adsorption box, supercharging
Pumping takes the dry gas in glove box, and the dry gas of extraction is transported in adsorption box, increases the pressure in adsorption box,
Adsorption box is set to be separated with pallet.
The present invention saves substantial amounts of N2 use costs completely without using N2.

Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
Lithium battery froth in vacuum device, including glove box 1, placement tray 2 in glove box 1, the top of pallet 2 place one or
Several battery cores 3, driving device 4 is installed near battery core 3, and driving device 4 can be suspended in glove box 1 by fixed plate, institute
State driving device 4 and connect adsorption box 5, driving device 4 drives adsorption box 5 to lift, adsorption box 5 is declined and hold pallet 2, make
Space between pallet 2 and adsorption box 5 is confined space, and after pallet 2 closes up with adsorption box 5, adsorption box 5 starts to extract battery core
Bubble in 3, bubble, which detaches completion, to be needed to fill dry gas toward in confined space, adsorption box 5 is separated with pallet 2.In the present invention,
The battery core 3 is all to be already equipped with the product of electrolyte, and fluid injection is carried out for battery core 3 using the priming device 6 in glove box 1.
Adsorption box 5 connects vacuum extractor 7 at the same time, is controlled and connected by controller between vacuum extractor 7 and adsorption box 5
Connect.After electrolyte injects, start driving device 4, adsorption box 5 declines to be snapped together with pallet 2, and adsorption box 5 is inhaled afterwards
The bubble in battery core 3 is taken, the bubble of absorption is stored in adsorption box 5, and controller starts vacuum extractor 7, by the air of absorption
Detach away, after air detaches, negative pressure is formed in adsorption box 5, adsorption box 5 is not readily disengaged from pallet 2, it is impossible to carries out next round
Work, therefore the installation booster pump 8 in the glove box 1, the booster pump 8 are connected with adsorption box 5, the extraction glove box 1 of booster pump 8
Interior dry gas, and the dry gas of extraction is transported in adsorption box 5, increase the pressure in adsorption box 5, make adsorption box 5
It can be separated with pallet 2.
After the completion of vacuum extractor 7 works, start booster pump 8, booster pump 8 extracts the dry gas in glove box 1, and will
The dry gas of extraction is transported in adsorption box 5, increase adsorption box 5 in pressure, when the pressure in adsorption box 5 close to or
Equal to outside (in glove box) pressure when, adsorption box 5 can be separated with pallet 2, and adsorption box 5 can be drawn in other battery core
Bubble, carry out above-mentioned work again.
The present invention provides pressure using itself dry gas in glove box for adsorption box, although being only simply to improve,
But nitrogen or other gases are no longer needed in whole workflow, can just with the dry gas in glove box
Realize the disengaging between adsorption box and pallet, save material, avoid wasting.
During work, many battery cores 3 can be put wait and be adsorbed, therefore in order to save manually, in work-yard
Conveyer belt 9 is set, and pallet 2 is all placed on conveyer belt 9, and after the completion of the bubble absorption of some battery core 3, control conveyer belt 9 moves
It is dynamic, next pallet and battery core 3 is moved to the lower section of adsorption box 5, reduce the work of worker.
It these are only the preferred embodiment of the embodiment of the present invention, be not intended to limit the invention embodiment, it is all at this
Within the spirit and principle of inventive embodiments, any modification, equivalent replacement, improvement and so on, should be included in of the invention real
Apply in the protection domain of example.
