Description
Technical field
The present invention relates to battery processing device technical field, particularly relate to battery liquid-filling equipment.
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 battery liquid-filling equipment, 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: battery liquid-filling equipment, comprise housing, the upper and lower two ends of described housing are respectively arranged with the first tapped 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 tapped through hole and the second through hole, described pin upper end of bleeding is connected with vacuum extractor, described pin of bleeding is provided with the external screw thread coordinated with described first tapped through hole, described in pin lower end diameter of bleeding be greater than the diameter of described second through hole.During this air extractor fluid injection, do not fit with housing in the bleed lower end of pin, pin of bleeding carries out air suction process, electrolyte in housing is injected in battery, and when fluid injection completes, pin of bleeding rotates the inner surface gluing, sealing extending into lower end and housing, pin of bleeding afterwards moves upward together with housing again, pin of bleeding before housing leaves liquid injection hole so has just blocked the second through hole, effectively prevents electrolyte from dropping onto outside battery, the fail safe that improve battery transport and use.
In technique scheme, preferably, described housing lower end is taper.Housing lower end is arranged to the efficiency that taper effectively can improve fluid injection.
In technique scheme, preferably, described housing lower end and battery liquid-filling mouth contact position are provided with the first sealing ring.First sealing ring is set in order to improve sealing property, make battery bleed and injection process in efficiency higher.
In technique scheme, preferably, pin lower end of bleeding described in is provided with the second sealing ring.The sealing raising that second sealing ring makes to bleed between pin and housing is set, prevents solution leakage.
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.
