Abstract
The invention discloses the battery liquid-filling equipment of antidrip, comprise injection needle and vacuumize housing, describedly vacuumize passage housing being provided with and connecting vacuum extractor, the described enclosure interior that vacuumizes is a cavity, the described housing upper surface that vacuumizes is provided with the first through hole, described injection needle is equipped with in described first through hole, sealing face is provided with bottom described injection needle, described sealing face is provided with the second through hole, the lower surface of housing is vacuumized described in described sealing face props up, described lower surface is provided with the third through-hole coordinated with described second through hole, described lower surface is also provided with aspirating hole.The present invention effectively prevents electrolyte drippage residual in injection needle, which prevent electrolyte and drops onto outside batteries, effectively raises the fail safe in battery transport and use procedure.
Description
Technical field
The present invention relates to battery processing device technical field, particularly relate to the battery liquid-filling equipment of antidrip.
Background technology
General lithium battery fluid injection operation adopts manual fluid injection in drying box or glove box, and efficiency is low, absorption is slow.Vacuum liquid filling is adopted effectively to solve the problem, general vacuum electrolyte filling device comprises vacuum extractor and priming device, the injection needle that priming device comprises height above sea level pump and is attached thereto, as shown in Figure 1, injection needle 1 is through cavity 21, injection needle 1 upper end connects height above sea level pump, injection needle 1 lower ending opening, cavity 21 is provided with passage 22 and is connected with vacuum extractor, a fixed gap is provided with between cavity 21 lower end and injection needle 1, carried out the vacuum pumping of battery 5 inside by this space, when carrying out fluid injection operation, injection needle 1 and the cavity 21 of this equipment move simultaneously.
When adopting said apparatus to carry out fluid injection, due to the surface tension of electrolyte, the electrolyte some is attached in injection needle, injection needle is extracted from inside battery the electrolyte adhered to afterwards and is easily dropped at outside batteries, and electrolyte has very strong corrosivity, therefore in this transport after battery and use procedure, there is very large potential safety hazard.
Summary of the invention
The present invention is directed to prior art deficiency, provide the battery liquid-filling equipment of antidrip, this kind of battery liquid-filling device can effectively prevent electrolyte from dropping onto the outside of battery, improves the fail safe in battery transport and use procedure.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: the battery liquid-filling equipment of antidrip, comprise injection needle and vacuumize housing, describedly vacuumize passage housing being provided with and connecting vacuum extractor, the described enclosure interior that vacuumizes is a cavity, described housing upper surface and the lower surface of vacuumizing is provided with the first coaxial through hole and the second through hole, in described first through hole, laminating is equipped with described injection needle, the sealing plate be rotationally connected with described lower surface is provided with below described second through hole, described sealing plate is circular plate body, described sealing plate upper surface is provided with fillet, described sealing plate side is provided with flange, described flange both sides are provided with rotating shaft, described rotating shaft is provided with torsion spring installing hole, described lower surface is provided with the groove coordinated with described flange.When fluid injection, lower surface props up the liquid injection hole of battery, injection needle moves downward, back down sealing plate, vacuum extractor carries out vacuum pumping, and injection needle carries out fluid injection, when fluid injection completes, injection needle moves upward, and the torsion spring effect on sealing plate makes sealing plate rotate and blocks the second through hole, and then injection needle moves upward together with vaccum case again.Outside batteries is dropped onto like this with regard to effectively prevent electrolyte residual in injection needle.
In technique scheme, preferably, described in vacuumize housing lower surface and be provided with boss, described second through hole is arranged on described boss.Arranging boss makes the liquid injection hole of battery easily aim at this priming device.
In technique scheme, preferably, described boss arranged outside has sealing ring.Arrange sealing ring to improve the sealing vacuumizing housing and battery, improve vacuumizing effect.
The present invention compared with prior art, has following beneficial effect: the present invention effectively prevents electrolyte drippage residual in injection needle, which prevent electrolyte and drops onto outside batteries, effectively raises the fail safe in battery transport and use procedure.
