Abstract
The invention discloses the battery liquid-filling device of antidrip, comprise housing, the upper and lower two ends of described housing are respectively arranged with the first through hole and the second through hole, described housing is also provided with passage, described expanding channels has height above sea level pump, pin of bleeding is equipped with in described first through hole and the second through hole, described pin upper end of bleeding is connected with vacuum extractor, described pin lower end of bleeding exceeds described second through hole, described pin lower end of bleeding is provided with the first flange, the external diameter of described first flange is greater than the aperture of described second through hole, described pin top of bleeding is provided with the second flange, spring is provided with between described second flange and described housing.The present invention can effectively prevent electrolyte from dropping onto the outside of battery, improves 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 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, injection needle is through cavity, injection needle upper end connects height above sea level pump, injection needle lower ending opening, cavity is provided with passage and is connected with vacuum extractor, a fixed gap is provided with between cavity lower end and injection needle, the vacuum pumping of inside battery is carried out by this space, when carrying out fluid injection operation, injection needle and the cavity of this device 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 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: the battery liquid-filling device of antidrip, comprise housing, the upper and lower two ends of described housing are respectively arranged with the first through hole and the second through hole, described housing is also provided with passage, described expanding channels has height above sea level pump, pin of bleeding is equipped with in described first through hole and the second through hole, described pin upper end of bleeding is connected with vacuum extractor, described pin lower end of bleeding exceeds described second through hole, described pin lower end of bleeding is provided with the first flange, the external diameter of described first flange is greater than the aperture of described second through hole, described pin top of bleeding is provided with the second flange, spring is provided with between described second flange and described housing.When fluid injection, the lower surface of housing props up the liquid injection hole of battery, pin of bleeding carries out air suction process, and due to atmospheric effect, pin of bleeding moves downward Compress Spring, bleed between pin lower end and housing and produce gap, electrolyte in housing is injected in battery, and when fluid injection completes, pin of bleeding stops bleeding, second through hole is blocked by bleed the first flange of pin lower end of the elastic force due to spring, and pin of bleeding afterwards moves upward together with housing.Outside batteries is dropped onto like this with regard to effectively prevent electrolyte residual in injection needle.
In technique scheme, preferably, the first sealing ring is provided with above described first flange.First sealing ring is set and can improves the sealing of bleeding between pin and housing.
In technique scheme, preferably, described housing lower surface is provided with boss, and 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 the second sealing ring.Second sealing ring is set to improve the sealing of housing and battery, improves fluid injection effect.
The present invention compared with prior art, has following beneficial effect: the present invention can effectively prevent electrolyte from dropping onto the outside of battery, improves the fail safe in battery transport and use procedure.
