Description
Technical field
The utility model belongs to battery production equipment field technology, is specially a kind of flexible liquid injecting mouth.
Background technology
, it is necessary to inject the electrolyte into inside battery when making lithium battery, contain metal ion in electrolyte, electric energy is risen
Conduction, so the quality of electrolyte and reservoir quantity directly determine the quality quality of lithium battery.
It is substantially all in the industry using vacuum liquid filling method in lithium battery fluid injection now.It is difficult in the fluid injection at the same time of multiple lithium batteries
Exempt to cause to contact between some liquid injection ports and battery liquid-filling mouth not enough, make its poor sealing, very because battery is scale error
To vacuum environment is destroyed, cause electrolyte to inject, seriously affect the batch quality of lithium battery.
Consequently, it is desirable to a kind of reliable and practical new departure is worked out to solve the above problems.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is that design provides a kind of flexible fluid injection
The technical solution of mouth, when multiple lithium batteries are in same station fluid injection, liquid injecting mouth is first contacted with cell cover, and liquid injecting mouth is being noted
Slided on liquid head, buffer spring is compressed, and the distance of flexible liquid injecting mouth automatic adjusument liquid injecting mouth and battery liquid-filling mouth, avoids
Liquid injecting mouth contacts not enough with battery liquid-filling mouth, and sealing is bad to be caused to can not achieve the generation of fluid injection such case.
A kind of flexible liquid injecting mouth, it is characterised in that including filling head, liquid injecting mouth, buffer spring, set in filling head
A through hole is put to be connected with liquid injecting mouth fitting as electrolyte passage, filling head, buffer spring be installed on filling head, liquid injecting mouth it
Between.
A kind of flexible liquid injecting mouth, it is characterised in that filling head lower part sets boss, and buffer spring connects with boss gear
Coordinate.
A kind of described flexible liquid injecting mouth, it is characterised in that one section of ring groove is set in the middle part of filling head, it is right on liquid injecting mouth
O-shaped sealing bulge loop should be set, and liquid injecting mouth, filling head are slidably matched by O-shaped sealing bulge loop, ring groove sealing.
A kind of flexible liquid injecting mouth, it is characterised in that filling head top sets inlet, and inlet is horn mouth knot
Structure.
A kind of flexible liquid injecting mouth, it is characterised in that liquid injecting mouth head sets V-groove.
A kind of flexible liquid injecting mouth, it is characterised in that the setting of liquid injecting mouth head connects tubaeform with electrolyte passage
Liquid outlet.
A kind of above-mentioned flexible liquid injecting mouth, when multiple lithium batteries are in same station fluid injection, liquid injecting mouth elder generation and cell cover
Contact, liquid injecting mouth slides on filling head, and buffer spring is compressed, and flexible liquid injecting mouth automatic adjusument liquid injecting mouth is noted with battery
The distance of liquid mouth, liquid injecting mouth and battery liquid-filling mouth sealing effect are good, have ensured the quality of lithium battery.
Brief description of the drawings

Embodiment
A kind of preferred solution of the utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in the figure, the flexibility liquid injecting mouth, including filling head 1, liquid injecting mouth 2, buffer spring 3, filling head 1 is interior to set one to lead to
Hole is connected as electrolyte passage 102, filling head 1 with 2 fitting of liquid injecting mouth, buffer spring 3 be installed on filling head 1, liquid injecting mouth 2 it
Between.1 lower part of filling head sets boss 104, and buffer spring 3 connects cooperation with the gear of boss 104, and boss 104 is led as buffer spring 3
To location structure.The middle part of filling head 1 sets one section of ring groove 103, and O-shaped sealing bulge loop 203, ring are correspondingly arranged on liquid injecting mouth 2
Sliding rail of the type groove 103 as liquid injecting mouth 2, O-shaped sealing bulge loop 203 are used as dynamic seal, and liquid injecting mouth 2, filling head 1 pass through
O-shaped sealing bulge loop 203, the sealing of ring groove 103 are slidably matched.1 top of filling head sets inlet 101, and inlet 101 is loudspeaker
Mouth structure.2 head of liquid injecting mouth sets V-groove 201, and V-groove 201 is used to increase the leakproofness between liquid injecting mouth 2 and battery.Fluid injection
2 head of mouth sets the tubaeform liquid outlet 202 connected with electrolyte passage 102.
The utility model has clear advantage and beneficial effect compared with prior art.Specifically, by above-mentioned technology
Scheme is understood, in fluid injection, liquid injecting mouth 2 is first contacted with cell cover, and liquid injecting mouth 2 slides on filling head 1,3 quilt of buffer spring
Compression, the distance of flexible liquid injecting mouth automatic adjusument liquid injecting mouth 2 and battery liquid-filling mouth.Electrolyte passes through 1 inlet of filling head
At 101 horn mouth, liquid injecting mouth 2 is entered by electrolyte passage 102, finally by 202 note of tubaeform liquid outlet of liquid injecting mouth 2
Enter into battery.Filling head 1 realizes dynamic sealing with liquid injecting mouth 2 by O-shaped sealing bulge loop 203, ring groove 103, is on liquid injecting mouth 2
V-groove 201 so that liquid injecting mouth 2 gets a promotion with the leakproofness at cell cover liquid injection port.
