Abstract
It the utility model is related to technical field of battery production, disclose a kind of battery liquid-filling head device, including fluid injection syringe needle, the tail end of fluid injection syringe needle has the jack of step, the front end of the fluid injection syringe needle has the indent step surface of annular, is disposed with the elastic sponge body and elastic rubber ring of annular from inside to outside in the outside of fluid injection syringe needle around the indent step surface.The present apparatus is provided with the elastic rubber ring of annular in the front end of fluid injection syringe needle, and during fluid injection, elastic rubber ring can be such that priming device and aluminum-shell battery effectively seals, it is therefore prevented that electrolyte leaks；Meanwhile have one layer of elastic sponge body inside elastic rubber ring, if run into the situation of seal failure, elastic sponge body then can effectively absorb the electrolyte of spilling, it is therefore prevented that electrolyte further leaks caused pollution.
Description
Technical field
It the utility model is related to the filling head dress used in technical field of battery production, more particularly to battery liquid-filling technique
Put.
Background technology
For current lithium ion battery with aluminum shell filling head device, when in use, due to priming device and battery case
The sealing problem of body, electrolyte is easily caused to be overflowed out of filling head or battery, because electrolyte has corrosivity, electrolyte
Overflow the pollution of burn into battery that can cause equipment, the destruction of environment and the health for influenceing operating personnel.Therefore, for this
One phenomenon is, it is necessary to design a kind of filling head device of sealed reliable.
Utility model content
In view of this, the application provides a kind of battery liquid-filling head device, ensures that fluid injection fills by using simple structure
The sealing between lithium ion battery with aluminum shell is put, when meeting seal failure, electrolyte can be effectively absorbed, prevented outside electrolyte
Let out caused pollution.
To solve above technical problem, technical scheme provided by the utility model is a kind of battery liquid-filling head device, including
Fluid injection syringe needle, the tail end of fluid injection syringe needle have the jack of step, and the front end of the fluid injection syringe needle has the indent step of annular
Face, the elastic sponge body of annular and elastic rubber are disposed with from inside to outside in the outside of fluid injection syringe needle around the indent step surface
Cushion rubber.
Preferably, the elastic sponge body and elastic rubber ring, its end relative to the fluid injection syringe needle end to
Outer protrusion.
Preferably, the elastic sponge body, it is interference fit between fluid injection syringe needle and elastic rubber ring.
Preferably, the material of the fluid injection syringe needle is corrosion resistant metal.
Preferably, the elastic sponge body is PU sponges, and its inside has some micropores.
Preferably, the jack can be fabricated to plurality of specifications, for being used cooperatively from the liquid-injection equipment of different dimensions.
Compared with prior art, its advantage describes in detail as follows the application：The present apparatus is set in the front end of fluid injection syringe needle
The elastic rubber ring of annular is equipped with, during fluid injection, elastic rubber ring can be such that priming device and aluminum-shell battery effectively seals, it is therefore prevented that electricity
Solution liquid leaks；Meanwhile have one layer of elastic sponge body inside elastic rubber ring, and if run into the situation of seal failure, elasticity sea
Continuous body then can effectively absorb the electrolyte of spilling, it is therefore prevented that electrolyte further leaks caused pollution, and the present apparatus is also
With the advantages of simple in construction, cost is low.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model；
In figure mark for：1- fluid injection syringe needles, 2- elastic sponge bodies, 3- elastic rubber rings, 4- jacks.
Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and have
The utility model is described in further detail for body embodiment.
As shown in figure 1, a kind of lithium ion battery with aluminum shell filling head device of the present utility model, including fluid injection syringe needle 1, noting
The tail end of liquid syringe needle 1 has the jack 4 of step, has the indent step surface of annular in the front end of fluid injection syringe needle 1, interior around this
Concave station terrace is disposed with the elastic sponge body 2 and elastic rubber ring 3 of annular in the outside of fluid injection syringe needle 1 from inside to outside.Bullet
Property cavernous body 2 and fluid injection syringe needle 1 and elastic sponge body 2 and elastic rubber ring 3 between be interference fit.The injection needle
First 1 material is corrosion resistant metal, and described elastic sponge body 2 uses PU sponges, and its inside has some micropores.
Elastic sponge body 2 and elastic rubber ring 3, its end are outwards slightly prominent relative to the end of the fluid injection syringe needle 1
Go out.
The internal diameter of fluid injection syringe needle jack 4 can be fabricated to plurality of specifications, for coordinating from the liquid-injection equipment of different dimensions
Use, this matching design facilitates the replacing and cleaning of filling head device.
During fluid injection, lithium ion battery with aluminum shell is positioned over to the underface of fluid injection syringe needle 1, ensures that fluid injection syringe needle 1 inserts battery
Liquid injection hole in, annular elastic rubber ring 3 and elastic sponge body 2 are brought into close contact with battery, ensure sealing, then again by electricity
Solve liquid injection inside battery.During fluid injection, elastic rubber ring 3 can effectively seal against priming device and aluminum-shell battery, it is therefore prevented that electricity
Solution liquid leaks, if run into the situation of seal failure, elastic sponge body 2 then can effectively absorb the electrolyte of spilling, prevent from being electrolysed
Liquid further leaks caused pollution.
It the above is only preferred embodiment of the present utility model, it is noted that above-mentioned preferred embodiment should not regard
For that should be defined to limitation of the present utility model, the scope of protection of the utility model by claim limited range.For
For those skilled in the art, do not departing from spirit and scope of the present utility model, can also make some
Improvements and modifications, these improvements and modifications also should be regarded as the scope of protection of the utility model.
