Problems solved by technology

However, for super-large-capacity soft-pack batteries, due to their relatively large weight and liquid injection volume, they are manually injected when they are injected. It takes a long time to set up, and the pre-packaging is also manually packaged under normal pressure with a simple device, which has an impact on the safety performance of the battery. Artificial also has some influence
In the process of manual handling of batteries, not only is the labor intensity high, but frequent handling also affects the pole pieces inside the battery, thus affecting the performance of the battery

Abstract

A power battery liquid-injection sealing machine of the invention belongs to a device for liquid injection, vacuum standing, and prepackaging of large capacity soft-pack lithium batteries. The machine comprises a guide rail mechanism, a main driving mechanism surrounding the guide rail mechanism, a carrier trolley mechanism, a transferring trolley mechanism, and orderly-disposed pre-liquid injection pre-vacuum pumping mechanism, an angular adjustment liquid injection mechanism, a post-liquid injection vacuum standing mechanism, and a prepackaging mechanism. The guide rail mechanism plays a guiding role, and allows the carrier trolley to be transported smoothly; the main driving mechanism is used to drive the carrier trolley; the carrier trolley mechanism is used to load a large capacity battery; the transferring trolley mechanism is used to realize the transferring of the carrier trolley. The device realizes liquid injection and prepackaging of large capacity batteries in a semi-automatic state, which reduces manual operation cost. A battery is allowed to be vacuumized and to stand with an optimal angle, and the electrolyte permeation efficiency is better.

Description

technical field [0001] The invention belongs to the field of design machinery manufacturing, and in particular relates to a large-power liquid injection machine for liquid injection and prepackaging of large-capacity soft-pack lithium batteries. Background technique [0002] At present, the outer casing of batteries is generally divided into metal casing and flexible packaging. In comparison, batteries prepared using flexible packaging can significantly reduce the manufacturing cost of batteries and increase the energy density and power density of batteries. However, for super-large-capacity soft-pack batteries, due to their relatively large weight and liquid injection volume, they are manually injected when they are injected. It takes a long time to set up, and the pre-packaging is also manually packaged under normal pressure with a simple device, which has an impact on the safety performance of the battery. Artificial also has a certain influence. The manual handling of...
