Description
Technical field
The present invention relates to the battery processing device technical field, relate in particular to battery liquid-filling equipment.
Background technology
General lithium battery fluid injection operation adopts manually fluid injection in drying box or glove box, and efficiency is low, absorption is slow.Adopt vacuum liquid filling effectively to address the above problem, general vacuum electrolyte filling device comprises vacuum extractor and priming device, priming device comprises height above sea level pump and the fluid injection pin that is attached thereto, the fluid injection pin passes cavity, fluid injection pin upper end connects the height above sea level pump, fluid injection pin lower ending opening, cavity is provided with passage and is connected with vacuum extractor, be provided with a fixed gap between cavity lower end and fluid injection pin, carry out the vacuum pumping of inside battery by this space, when carrying out the fluid injection operation, fluid injection pin and the cavity of this device move simultaneously.
When adopting said apparatus to carry out fluid injection, surface tension due to electrolyte, the electrolyte of understanding some is attached on the fluid injection pin, the fluid injection pin is extracted above rear from inside battery the electrolyte that adheres to and is easily dropped at outside batteries, and electrolyte has very strong corrosivity, so has very large potential safety hazard in this transportation after battery and use procedure.
Summary of the invention
The present invention is directed to the prior art deficiency, battery liquid-filling equipment is provided, this kind battery liquid-filling device can prevent effectively that electrolyte from dropping onto the outside of battery, improves the fail safe in battery transportation 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, two ends, described housing up and down are respectively arranged with the first tapped through hole and the second through hole, also be provided with passage on described housing, described passage is connected with the height above sea level pump, be equipped with the pin of bleeding in described the first tapped through hole and the second through hole, the described pin upper end of bleeding is connected with vacuum extractor, be provided with the external screw thread that coordinates with described the first tapped through hole on the described pin of bleeding, the described diameter of pin lower end diameter greater than described the second through hole of bleeding.During this air extractor fluid injection, do not fit with housing in the bleed lower end of pin, the pin of the bleeding operation of bleeding, electrolyte in housing is injected in battery, and when fluid injection was completed, the pin of bleeding rotated the inner surface gluing, sealing that extend into lower end and housing, the pin of bleeding afterwards moves upward again together with housing, the pin of bleeding before housing leaves liquid injection hole has so just been blocked the second through hole, prevents that effectively electrolyte from dropping onto the battery outside, the fail safe that has improved the battery transportation and used.
In technique scheme, preferred, described housing lower end is taper.Taper is arranged in the housing lower end can effectively improves the efficiency of fluid injection.
In technique scheme, preferred, described housing lower end and battery liquid-filling mouth contact position are provided with the first sealing ring.The first sealing ring is set in order to improve sealing property, make battery bleed and the fluid injection process in efficiency higher.
In technique scheme, preferred, the described pin lower end of bleeding is provided with the second sealing ring.The second sealing ring is set makes the sealing of bleeding between pin and housing improve, prevent solution leakage.
The present invention compared with prior art, has following beneficial effect: the present invention can prevent effectively that electrolyte from dropping onto the outside of battery, improves the fail safe in battery transportation and use procedure.
