Abstract

The utility model discloses a temporary sealing device for square lithium ion battery opening formation. The square lithium ion battery opening formation temporary sealing device comprises a conduction pipe with running-through inside, wherein the upper end of the conduction pipe is connected with a spray guard, the middle position of the conduction pipe is provided with a supporting hood, a material which easily absorbs electrolyte is installed in the spray guard, and a top cover of the spray guard is uniformly provided with small holes. By adopting the temporary sealing device for square lithium ion battery opening formation, the problem of the electrolyte spray in a battery in the production formation process of the lithium ion battery can be solved; the temporary sealing device is simple in design, capable of being molded in an injection manner through a simple mold, simple to operate, reusable and capable of avoiding the waste of material.

Description

The interim closing device of rectangular lithium ion battery open formation
Technical field
The utility model relates to closing device technical field, relates in particular to a kind of for the interim closing device of lithium ion battery open formation.
Background technology
Due to the appearance of energy resource consumption and problem of environmental pollution, lithium ion battery has been widely used on portable computer, camera, video camera, electric tool, pure battery and hybrid vehicle because of its high-energy-density, wide temperature working range and superior cycle performance, and will aspect artificial satellite, Aero-Space and energy storage, be applied.Lithium ion battery can divide box hat, aluminum hull and soft bag lithium ionic cell according to its outsourcing material.After lithium ion battery needs fluid injection in production process process, lithium ion battery changes into first, box hat and lithium ion battery with aluminum shell adopt open formation technique conventionally at present, be conducive to like this get rid of in formation process due between electrolyte and active material and react the gas producing, but in actual aperture formation process due to the resulting from discharge and can cause the ejection of the unnecessary electrolyte of inside battery of inside battery gas, the electrolyte gushing out can corrode formation device and easily cause the generation of the problems such as environmental pollution.
In manufacture process, conventionally adopt at present foam to encapsulate liquid injection port temporarily and prevent electrolyte hydrojet, but the foam of Interim use is disposable use and can not all solves battery and change into exhaust, electrolyte hydrojet problem; Plant personnel back and forth operates pastes foam labour intensity great Yi generation fatigue and seals foam temporarily follow-up envelope liquid injection port operation is caused to the problems such as new cleaning, therefore for current problem, has designed a kind of for the interim closing device of lithium ion battery open formation.
Utility model content
The purpose of this utility model is to overcome the defect of existing production technology, provides a kind of for the interim closing device of lithium ion battery open formation,
The purpose of this utility model can be achieved through the following technical solutions:
The interim closing device of rectangular lithium ion battery open formation, comprise the conduction pipe of inner conducting, described conduction pipe upper end is connected with spray guard, and medium position is provided with support cover, easy suction electrolyte material is housed in described spray guard, and spray guard top cover is provided with equally distributed aperture.
The radius of described support cover is greater than battery cover board liquid injection hole radius.
Described easy suction electrolyte material is sponge or fiber.
Described conduction pipe, support cover, spray guard are injection molded into mould by polyethylene or polypropylene material through corresponding mould and form.
The diameter of described conduction pipe and battery seal diameter of the steel ball adapt, and described conduction pipe lower end head is oval.
The beneficial effects of the utility model: the utility model has solved lithium ion battery and produced inside battery electrolyte hydrojet problem in formation process process; This utility model simplicity of design, can by the moulding of simple die injection molding and operate simple and easy, can repeatedly use and avoid material waste.
Brief description of the drawings
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the utility model front view.
Fig. 2 is the utility model vertical view.
Embodiment
As shown in Figure 1, the interim closing device of rectangular lithium ion battery open formation, it comprises the conduction pipe 1 of inner upper and lower conducting and the support cover 2 that medium position is provided with, the radius of described support cover 2 is greater than battery cover board liquid injection hole radius, for covering liquid injection hole.Conduction pipe 1 upper end is connected with the spray guard 3 that prevents electrolyte ejection, and spray guard 3 is square.Easy suction electrolyte material 4 is housed in described spray guard 3, easily inhales electrolyte material 4 for sponge or fiber material, and on spray guard 3 top covers, have equally distributed aperture 5.Described conduction pipe, support cover, spray guard are injection molded into mould by polyethylene or polypropylene material through corresponding mould and form.
Operation principle of the present utility model:
As shown in Figure 2, by rectangular cell good fluid injection after fluid injection frame takes off, this utility model conduction pipe 1 lower end oval head is inserted to liquid injection port to support cover 2 and can cover liquid injection port completely, battery its electrolyte inside in formation process enters in spray guard 3 by conduction pipe 1 with the gas producing, and electrolyte absorbs and the uniform small pores eliminating of gas above spray guard through sponge or fiber.Treat directly this utility model closing device to be taken off for next batch battery and changes into use after battery has changed into.This utility model is reciprocally used effective employee's work degree that improved production efficiency, saves production cost and reduced.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, all should belong to protection range of the present utility model.
