Abstract
The utility model discloses battery electrolyte injection equipment capable of preventing electrolyte dripping. The equipment comprises an electrolyte injection needle and a vacuumized shell, wherein the vacuumized shell is provided with a channel connected with a vacuumizing device; a cavity is formed inside the vacuumized shell; a first through hole is formed in the upper end face of the vacuumized shell; the electrolyte injection needle is arranged in the first through hole in a penetrating manner; a sealing surface is arranged at the bottom of the electrolyte injection needle; a second through hole is formed in the sealing surface; the sealing surface pushes against a lower end face of the vacuumized shell; a third through hole matched with the second through hole is formed in the lower end face; a bleeder hole is also formed in the lower end face. The equipment effectively prevents the residual electrolyte in the electrolyte injection needle from dripping, thus preventing the electrolyte from dripping outside the battery and effectively improving the safety in the battery transport and using processes.
Description
Technical field
The utility model relates to the battery processing device technical field, relates in particular to a kind of battery liquid-filling equipment of antidrip.
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 be attached thereto, as shown in Figure 1, fluid injection pin 1 is through 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 electrolyte that the 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, for the prior art deficiency, provides a kind of battery liquid-filling equipment of antidrip, 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: a kind of battery liquid-filling equipment of antidrip, 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, the described housing upper surface that vacuumizes is provided with the first through hole, be equipped with described fluid injection pin in described the first through hole, described fluid injection pin bottom is provided with sealing face, be provided with the second through hole on described sealing face, described sealing face props up the described lower surface that vacuumizes housing, be provided with the third through-hole coordinated with described the second through hole on described lower surface, also be provided with aspirating hole on described lower surface.The priming device of this structure is when fluid injection, the fluid injection pin is with to vacuumize the vertical relative position of housing constant all the time, vacuumize the liquid injection hole that the housing lower end props up battery, now the second through hole communicates with third through-hole, now vacuum extractor carries out vacuum pumping, the fluid injection pin carries out the fluid injection operation, when completing the fluid injection operation, the fluid injection pin turns to the second through hole and does not communicate with third through-hole, fluid injection pin and vacuumize housing and move upward simultaneously afterwards, when the fluid injection pin with when vacuumizing housing and leaving the battery liquid-filling hole, because the second through hole communicates with third through-hole, 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 aim at 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 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.

The cutaway view that Fig. 1 is background technology.
The cutaway view that Fig. 2 is the utility model embodiment state one.
The cutaway view that Fig. 3 is the utility model embodiment state two.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 2 to Fig. 3, a kind of battery liquid-filling equipment of antidrip, comprise fluid injection pin 1 and vacuumize housing 2, described vacuumizing on housing 2 is provided with the passage 22 that connects vacuum extractor, described housing 2 inside that vacuumize are a cavity 21, described housing 2 upper surfaces 23 that vacuumize are provided with the first through hole a, be equipped with described fluid injection pin 1 in described the first through hole a, described fluid injection pin 1 bottom is provided with sealing face 11, be provided with the second through hole b on described sealing face 11, described sealing face 11 props up the described lower surface 24 that vacuumizes housing 2, be provided with the third through-hole c coordinated with described the second through hole b on described lower surface 24, also be provided with aspirating hole d on described lower surface 24.
Described housing 2 lower surfaces 24 that vacuumize are provided with boss 3, and described the second through hole b is arranged on described boss 3.Boss 3 is set makes the liquid injection hole 51 of battery 5 easily aim at this priming device.
Described boss 3 arranged outside have sealing ring 4.Sealing ring 4 is set and improves the sealing that vacuumizes housing 2 and battery 5, improve vacuumizing effect.
