Description
Technical field
The utility model relates to battery processing device technical field, relates in particular to battery liquid-filling device.
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 being attached thereto, as shown in Figure 1, fluid injection pin 1 is through cavity 21, fluid injection pin 1 upper end connects height above sea level pump, fluid injection pin 1 lower ending opening, cavity 21 is provided with passage 22 and is connected with vacuum extractor, between cavity 21 lower ends and fluid injection pin 1, be provided with a fixed gap, by this space, carry out the vacuum pumping of battery 5 inside, when carrying out fluid injection operation, the fluid injection pin 1 of this equipment and cavity 21 move simultaneously.
When adopting said apparatus to carry out fluid injection, surface tension due to electrolyte, the electrolyte of understanding some is attached on fluid injection pin, the electrolyte that fluid injection pin adheres to above from inside battery is extracted easily drops at outside batteries, and electrolyte has very strong corrosivity, so there is very large potential safety hazard in this transportation after battery and use procedure.
Summary of the invention
The utility model is not enough for prior art, and battery liquid-filling device is provided, and this kind of battery liquid-filling device can effectively prevent 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 utility model is solved by following technical proposals: battery liquid-filling device, comprise fluid injection pin and vacuumize housing, the described passage that is provided with connection vacuum extractor on housing that vacuumizes, the described enclosure interior that vacuumizes is a cavity, describedly vacuumize housing upper surface and lower surface is provided with the first coaxial through hole and the second through hole, in described the first through hole and the second through hole, be equipped with described fluid injection pin, described fluid injection needle end part sealing, described fluid injection pin sidewall is provided with at least one third through-hole, on described the second through-hole side wall, be provided with groove, in described groove, be provided with slide block, described slide block upper surface is an inclined-plane, described slide block is connected with spring, the described spring other end is fixed in described groove, described slide block coordinates with described third through-hole.The priming device of this structure is when fluid injection, fluid injection pin moves downward with respect to vacuumizing housing, vacuumize the liquid injection hole that housing lower end props up battery, now electrolyte is injected into inside battery from third through-hole, vacuumize the housing operation of bleeding, when completing fluid injection operation, first fluid injection pin moves up to slide block and blocks third through-hole, fluid injection pin and vacuumize housing and move upward simultaneously afterwards, therefore in fluid injection pin, residual electrolyte is difficult to drippage, prevented that like this electrolyte from dropping onto outside batteries, effectively raise the fail safe in battery transportation and use procedure.
In technique scheme, preferred, described in vacuumize housing lower surface and be provided with boss, described the second through hole is arranged on described boss.Boss is set easily aims at the liquid injection hole of battery with this priming device.
In technique scheme, preferred, described boss arranged outside has sealing ring.Sealing ring is set and improves the sealing that vacuumizes housing and battery, improve vacuumizing effect.
The utility model compared with prior art, has following beneficial effect: the utility model effectively prevents electrolyte drippage residual in fluid injection pin, has prevented that like this electrolyte from dropping onto outside batteries, effectively raises the fail safe in battery transportation and use procedure.
