Abstract
The utility model discloses a liquid injecting device for a battery. The liquid injecting device for the battery comprises a liquid injecting needle and a vacuumizing shell, wherein the vacuumizing shell is provided with a channel connected with a vacuumizing device, the interior of the vacuumizing shell is provided with a cavity, and a first through hole and a second through hole which are coaxial are respectively formed at the upper end surface and lower end surface of the vacuumizing shell, the liquid injecting needle is arranged inside the first through hole and the second through hole in a penetrating manner, the diameter of the lower end of the liquid injecting needle is less than that of the upper end of the liquid injecting needle, and a turning block is arranged at the lower end of the liquid injecting needle, the side wall of the turning block is jointed with the inner wall of the liquid injecting needle, the lower end of the turning block exceeds the lower end of the liquid injecting needle, and a spiral channel is arranged inside the turning block. According to the liquid injecting device for the battery provided by the utility model, during liquid injecting, an electrolyte is ejected from the spiral channel of the turning block, so that the turning block is pushed to rotate, a sprinkling effect is formed, and the electrolyte injecting area is expanded, the electrode absorbing speed of an electrode plate is quicker, electrolyte stacking is reduced, and the liquid injecting efficiency is improved.
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.
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, because electrolyte compares thickness, when carrying out fluid injection, battery lead plate Electolyte-absorptive speed is slower, and electrolyte will be deposited on the battery lead plate of fluid injection pin below, makes fluid injection efficiency very low.
Summary of the invention
The utility model, for the prior art deficiency, provides a kind of battery liquid-filling equipment, and this kind of battery liquid-filling equipment can enlarge the spray area of electrolyte, effectively improves fluid injection efficiency.
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, 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 pin lower end diameter is less than upper end diameter, described fluid injection pin lower end is provided with switch block, described switch block sidewall and the laminating of described fluid injection pin inwall, described switch block lower end exceeds described fluid injection pin lower end, be provided with spirality channel in described switch block.This liquid-injection equipment is when fluid injection, and electrolyte sprays in the spirality channel of switch block, promotes switch block and rotates, forming spray effect makes the injection area of electrolyte increase, thereby make the speed of battery lead plate Electolyte-absorptive accelerate, reduce electrolyte and pile up, thereby improve fluid injection efficiency.
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, have following beneficial effect: the utility model is when fluid injection, electrolyte sprays in the spirality channel of switch block, the promotion switch block rotates, forming spray effect makes the injection area of electrolyte increase, thereby make the speed of battery lead plate Electolyte-absorptive accelerate, reduce electrolyte and pile up, thereby improve fluid injection efficiency.
