Problems solved by technology

In view of the model change, there is a problem of difficulty in injecting liquid during the research and development process, because the current liquid injection machine is mainly designed for industrial production, and its advantages are high liquid injection efficiency, high pass rate, and strong specificity. One filling machine can only fill the same type of battery, different types of batteries need different filling machines, the cost is too high

Abstract

The invention proposes a square shell battery manual liquid injection fixture, which includes a support frame and a plurality of liquid injection components; The plate is located above the base and its two ends are respectively connected with two connection plates; multiple liquid injection components are installed on the mounting plate at intervals and the distance between any two adjacent liquid injection components is adjustable. The invention can effectively utilize the atmospheric pressure to increase the pressure of the electrolyte solution during liquid injection, thereby effectively improving the liquid injection efficiency. If the battery model is replaced, only the liquid injection head that matches the battery needs to be replaced, and multiple types of batteries can be processed. Injection.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a manual liquid injection jig for a square shell battery. Background technique [0002] Lithium-ion batteries are widely used in mobile communications, notebooks, electric vehicles and other industries due to their advantages such as high energy density, light weight, long service life, low self-discharge rate, and no memory effect. However, while lithium-ion batteries are widely used, there are also requirements for its energy density, especially for passenger cars, which put forward higher requirements for mileage. [0003] Energy density is a very important control item of the battery. To improve the energy density of the battery is mainly through the change of the material and the change of the battery model. In view of the model change, there is a problem of difficulty in injecting liquid during the research and development process, because the current liquid injection ma...
