Description
Technical field
The present invention relates to the battery processing device technical field, relate 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 that is attached thereto, as shown in Figure 1, fluid injection pin 1 passes cavity 21, fluid injection pin 1 upper end connects the 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, be provided with a fixed gap between cavity 21 lower ends and fluid injection pin 1, carry out the vacuum pumping of battery 5 inside by this space, when carrying out the 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 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 device 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 device, comprise the fluid injection pin and vacuumize housing, described vacuumizing on housing is provided with the passage that connects vacuum extractor, the described enclosure interior that vacuumizes is a cavity, describedly vacuumize the housing upper surface and lower surface is provided with the first coaxial through hole and the second through hole, be equipped with described fluid injection pin in described the first through hole and the second through hole, described fluid injection needle end part sealing, described fluid injection pin sidewall is provided with at least one third through-hole, be provided with groove on described the second through-hole side wall, be provided with slide block in described groove, 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, the fluid injection pin moves downward with respect to vacuumizing housing, vacuumize the liquid injection hole that the housing lower end props up battery, this moment, electrolyte was injected into inside battery from third through-hole, vacuumize the housing operation of bleeding, when completing the fluid injection operation, at first the 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 the 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, the described housing lower surface that vacuumizes is provided with boss, and described the second through hole is arranged on described boss.Boss is set makes the liquid injection hole of battery easily with this priming device, aim at.
In technique scheme, preferred, described boss arranged outside has sealing ring.Sealing ring is set improves the sealing that vacuumizes 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 the 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.
