Description
Technical field
The present invention relates to battery processing device technical field, particularly relate to a kind of battery liquid-filling device 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 a kind of battery liquid-filling device 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: a kind of battery liquid-filling device 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, described first through hole and the interior laminating of the second through hole are equipped with described injection needle, described injection needle lower end is rotatably connected to the moving block of the composition seal that cooperatively interacts, described vaccum case lower surface is provided with aspirating hole.The priming device of this structure is when fluid injection, injection needle moves downward relative to vacuumizing housing, vacuumize the liquid injection hole that housing lower end props up battery, the moving block of injection needle lower end is opened, now vacuum extractor carries out vacuum pumping, injection needle carries out fluid injection operation, when completing fluid injection operation, first injection needle moves upward, in the process that injection needle moves upward, moving block enters in the second through hole, moving block closes composition seal, so residual in injection needle electrolyte is difficult to drippage, which prevent electrolyte and drop onto outside batteries, effectively raise the fail safe in battery transport and use procedure.
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.
