Description

A kind of lithium battery negative pressure formation device
Technical field
The utility model belongs to technical field of battery production, specifically a kind of lithium battery negative pressure formation device.
Background technology
Monomer lithium ion battery is in activation process first, due to the formation of SEI film, it can produce a large amount of gas, and therefore battery can not at once by battery seal after injection electrolyte, generally all adopt open formation, to ensure that the gas changing into period generation can be discharged in time.So, can carry partial electrolyte liquid out when changing into the gas overflowing of generation, if do not take appropriate measures means, these electrolyte overflowed and the gas produced when changing into can pollute whole workshop, affect environment.The way of current most of producer puts a fritter foamed glue or absorbent cotton after fluid injection to tie up an adhesive tape again above overflow to prevent electrolyte at liquid injection port place, but poor effect and the spilling of electrolyte can not be stopped completely, and whole process is more and loaded down with trivial details, efficiency is very low, mention a kind of square aluminum-shell lithium battery negative pressure in utility model patent CN203553288U and change into servicing unit, but the collection process of the gas be pumped when unresolved negative pressure changes into and waste electrolyte.
Utility model content
For the technical problem existed in prior art, the purpose of this utility model is to provide a kind of lithium battery negative pressure formation device, the collection solving waste liquid is convenient to focus on, after changing into end, fill a certain amount of nitrogen again to ensure the consistency of battery inner and outer air pressure simultaneously, thus ensure that battery with two side terminals better.
The utility model can be implemented by the following technical programs:
A kind of lithium battery negative pressure formation device, comprise body, described body the first half is hollow cuboid, the latter half is open inverted triangles, valve is provided with bottom open inverted triangles, body side is provided with several drainage tubes, drainage tube quantity is corresponding with the number of batteries changed into, body opposite side is deflecting gas tube, deflecting gas tube is connected with triangle valve, triangle vavle door is by controlling the folding of vacuum tube and nitrogen tracheae thus the mutual switching that control between vacuum and nitrogen, described hollow cuboid centre position is provided with a gas-liquid baffler, described gas-liquid baffler connects the front-back of hollow cuboid top and hollow cuboid, for the corrosion-resistant shape sheet of cuboid netted plastic.
Preferably, body is electrolyte resistance corrosion material, disposable injection molded.
Preferably, drainage tube and deflecting gas tube are corrosion-resistant material.
The beneficial effects of the utility model: the utility model is simple to operate, in process of production, the energy centralized collection such as the waste liquid that Battery formation produces, are convenient to cleaning, and also improve formation workshop environment, support personnel, product and device security improve production efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, Reference numeral implication is as follows:
1, body, 2, gas-liquid baffler, 3, drainage tube, 4, del converges liquid bath, 5, valve, 6, vacuum tube, 7, triangle valve, 8, nitrogen tracheae, 9, hollow cuboid, 10, open inverted triangles, 11, deflecting gas tube.
Embodiment
Below in conjunction with the utility model execution mode, be clearly and completely described the technical scheme in the utility model execution mode, obviously, described execution mode is only the utility model part execution mode, instead of whole execution modes.
The utility model provides a kind of lithium battery negative pressure formation device, as shown in Figure 1, comprise body 1, described body 1 the first half is hollow cuboid 9, the latter half is open inverted triangles 10, described open inverted triangles 10 top down, open inverted triangles 10 is inner is taper remittance liquid bath 4, be convenient to the convergence of waste electrolyte, described open inverted triangles 10 top is provided with valve 5, body 1 side is provided with several drainage tubes 3, drainage tube 3 quantity is corresponding with the number of batteries changed into, body 1 opposite side is deflecting gas tube 11, deflecting gas tube 11 is connected with triangle valve 7, triangle valve 7 is by controlling vacuum tube 6 and nitrogen tracheae 8 folding thus the mutual switching that control between vacuum and nitrogen, described hollow cuboid 9 centre position is provided with a gas-liquid baffler 2, described gas-liquid baffler 2 connects the front-back of hollow cuboid 9 top and hollow cuboid 9, described gas-liquid baffler 2 is cuboid plastic corrosion-resisting shape sheet, under negative pressure condition, gas-liquid baffler 2 prevents electrolyte from entering in vacuum tube 6.
Body 1 is electrolyte resistance corrosion material, disposable injection molded; Drainage tube 3 and deflecting gas tube 11 are corrosion-resistant material.
The utility model lower end arranges del remittance liquid bath 4, fundamentally solve the collection problem of waste liquid, waste liquid is convenient to focus on by del remittance liquid bath 4, hollow cuboid 9 inside is provided with gas liquid baffler 2, when avoiding vacuumizing, waste liquid is directly taken away, after changing into end, fill a certain amount of nitrogen again to ensure the consistency of battery inner and outer air pressure simultaneously, thus ensure that battery with two side terminals better.
When formation of Li-ion batteries is under negative pressure condition, waste gas in side deflecting gas tube 11 and electrolyte, be sprayed onto on gas liquid baffler 2, electrolyte along with own wt, can flow to del below and converges in liquid bath 4, mainly prevent electrolyte from entering vacuum tube 6, when in del converges liquid bath 4, waste liquid reaches a certain amount of, open valve 5, reclaim in time, simple to operation.
Below only have expressed a kind of execution mode of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
