Abstract
The utility model relates to a liquid injection device and specifically relates to a liquid injection device of a lithium ion battery. The liquid injection device comprises an electric core, an insulation sheet, an upper cover and a housing. The liquid injection device is characterized in that small holes are uniformly distributed on the insulation sheet, wherein the insulation sheet is tightly adhered with the upper part of the electric core in the housing; a groove of the insulation sheet is stuck with a lug edge on the electric core and fixed on the lug edge; a pole post base of the upper cover is arranged between two lugs; the upper cover is connected and fastened with lugs on the electric core by a bolt. The electric core is firmly packaged by a wide adhesive tape, the integral electric core is arranged in the housing, and the electric core and the housing are tightly assembled. According to the liquid injection device of the lithium ion battery, the internal structure of a battery is improved, and an uneven stress phenomenon of the electric core is reduced. The small holes on the insulation sheet are uniformly distributed for guiding electrolyte to flow into the electric core in a balanced manner. Moreover, the realizing way is simple, device investment is not increased and usage cost is low, and therefore, the liquid injection device is easy to realize.
Description
Technical field
The utility model relates to a kind of battery liquid-filling device, specifically a kind of lithium-ion battery liquid injection device.
Background technology
At present, the power vehicle battery is mainly used high-capacity lithium-ion power battery, makes it have energy density high, the advantages such as the life-span is long, although technique and selection are in continuous progress, but still the place had much room for improvement: in the fluid injection process, electrolyte is too concentrated, is not easy to the balanced Electolyte-absorptive of battery core.Existing fluid injection mode is that battery is placed directly on filling machine and vacuumizes a fluid injection, and electrolyte directly injects battery core from liquid injection port.From liquid injection hole, disposable fluid injection meeting causes the battery core imbibition inhomogeneous, and liquid injection port place liquid absorption is many, and pressure is large, causes the inside battery structural change.
Summary of the invention
When the purpose of this utility model is to provide a kind of fluid injection, electrolyte equiblibrium mass distribution, battery core infiltrate uniform lithium-ion battery liquid injection device.
The utility model comprises battery core, insulating trip, upper cover, housing, it is characterized in that the aperture be evenly distributed on insulating trip, battery core top in insulating trip and housing is close to, the groove of insulating trip blocks the lug edge on battery core, and be fixed on the lug limit, the pole base of upper cover is positioned between two lugs, and upper cover is connected fastening with the lug on battery core with bolt.
By wide adhesive tape parcel firmly, whole battery core is positioned at housing to above-mentioned battery core, and battery core and housing tightly assemble.
Above-mentioned insulating trip is the PP material of insulation and electrolyte resistance corrosion.
Using method is as follows: the battery core carrying jig is put into to positioning tooling fixture and fix to clamp, along the lug direction, put into insulating trip, insulating trip and battery core top are close to, the groove of insulating trip blocks the lug edge, be fixed on the lug limit, the pole base of upper cover is put between two lugs, be connected upper cover fastening with bolt with cell polar ear, take off fixture, by battery core with wide adhesive tape parcel firmly, whole battery core is put into housing, and battery core and housing tightly assemble.
The battery container of putting into battery core is placed in filling machine, the priming machine, electrolyte can flow in battery core uniformly along the aperture on insulating trip, is conducive to the formation of SEI film, alleviates the impulse force of electrolyte to battery core.
The utility model has the following advantages compared with prior art:
The utility model has improved the internal structure of battery, reduces the phenomenon of battery core unbalance stress.Aperture on insulating trip is uniformly distributed, the inflow battery core of guiding electrolyte equilibrium.Implementation is simple, does not increase equipment investment, and use cost is low, is easy to realize.
The accompanying drawing explanation
Fig. 1 is perspective view of the present utility model,
Fig. 2 is the schematic diagram of the utility model insulating trip.
In figure: 1. upper cover, 2. insulating trip, 3. aperture, 4. housing, 5. battery core, 6. lug, 7. groove.
Embodiment
The utility model comprises battery core 5, insulating trip 2, upper cover 1, housing 4, the aperture 3 be evenly distributed on insulating trip 2, battery core 5 tops in insulating trip 2 and housing 4 are close to, and the groove 7 of insulating trip 2 blocks lug 6 edges on battery core 5, and be fixed on lug 6 limits on battery core 5, the pole base of upper cover 1 is positioned at 6 of two lugs, and upper cover 1 is connected fastening with lug 6 use bolts on battery core 5, and battery core 5 by wide adhesive tape parcel firmly, whole battery core 5 is positioned at housing 4, and battery core 5 and housing 4 tightly assemble.
Above-mentioned insulating trip is the PP material of insulation and electrolyte resistance corrosion.
Using method is as follows: battery core 5 carrying jigs are put into to positioning tooling fixture and fix to clamp, along lug 6 directions, put into insulating trip 2, insulating trip 2 and battery core 5 tops are close to, the groove 7 of insulating trip 2 blocks lug 6 edges, be fixed on lug limit 6, the pole base of upper cover 1 is put into to 6 of two lugs, be connected upper cover 1 fastening with cell polar ear 6 use bolts with screwdriver, take off fixture, by the wide adhesive tape parcel of battery core 5 use firmly, whole battery core 5 is put into housing 4, and battery core 5 and housing 4 tightly assemble.
The battery container of putting into battery core is placed in filling machine, the priming machine, electrolyte can flow in battery core uniformly along the aperture on insulating trip, is conducive to the formation of SEI film, alleviates the impulse force of electrolyte to battery core.
