Flared liquid injection structure based on liquid injection device

Abstract

The invention relates to a flared liquid injection structure based on a liquid injection device. The flared liquid injection structure comprises a transverse movement component and a lifting componentarranged at the bottom of the transverse movement component, wherein a butt joint component is arranged at the bottom of the lifting component, and comprises at least one group of symmetrically arranged flared suction nozzles, the flared suction nozzles are arranged on a connecting plate at the bottom of the lifting component in a relative sliding way, a liquid injection needle is arranged between the two flared suction nozzles, the top end of the liquid injection needle is connected with a liquid hopper, and the liquid hopper is connected with the lifting component by virtue of a lifting screw. The flared liquid injection structure provided by the invention has the advantages that the flared suction nozzles are in fit with the liquid injection needle, liquid injection difficulty is greatly reduced, the neglected loading rate of an NG product is reduced, and production efficiency is improved; meanwhile, structure is simple, maintenance and repair are facilitated, and cost is low.

Description

technical field [0001] The invention relates to the field of battery cell liquid injection, in particular to a flared liquid injection structure based on a liquid injection device. Background technique [0002] Lithium-ion battery is a new generation of green high-energy battery with excellent performance, and has become one of the focuses of high-tech development. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, small internal resistance, less self-discharge, and more cycles. Due to the above characteristics, lithium-ion batteries are widely used in many civilian and military fields such as mobile phones, notebook computers, and tablet computers. [0003] In the production process of soft-packed lithium batteries, it is generally necessary to package the battery cells. In the traditional lithium battery production process, the technology and method of battery packaging are us...

AI Technical Summary

Problems solved by technology

The traditional production method of artificially injecting liquid into the battery has become increasingly unable to meet the development requirements of the times due to its low production efficiency and low product quality.

[0005] In addition, in the prior art, multiple production line-type mechanisms are used to cooperate in the production and processing of battery cell injection, which occupies a large area and is inconvenient to move. The process is integrated in the same machine
