Liquid injection machine

Abstract

The invention belongs to the technical field of battery liquid injection, and discloses a liquid injection machine which comprises a material conveying line, liquid injection clamps, a mold separating and closing device, a liquid injection device, a bell jar device and a carrying device, the material conveying line comprises a first conveying mechanism and a second conveying mechanism, and the liquid injection clamps comprise the first liquid injection clamp and the second liquid injection clamp. And when the first liquid injection clamp and the second liquid injection clamp are oppositely closed, the liquid injection cup is communicated with the battery, and the mold separating and closing device can oppositely close or separate the first liquid injection clamp and the second liquid injection clamp. According to the liquid injection machine provided by the invention, the first liquid injection clamp and the second liquid injection clamp are subjected to mold closing, liquid injection is performed through the liquid injection device, after liquid injection is completed, the liquid injection clamps are transferred to the bell jar device through the carrying device for standing, in the process that the electrolyte is absorbed into the battery, the electrolyte in the liquid injection cup can be supplemented into the battery, secondary liquid injection of the battery is not needed, and the production efficiency is improved. And the liquid injection process can be effectively simplified, the manufacturing period of the battery is shortened, and the production cost of the battery is reduced.

Description

technical field [0001] The invention relates to the technical field of battery liquid injection, in particular to a liquid injection machine. Background technique [0002] Lithium-ion battery is a secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. It has the characteristics of fast charging and discharging, high output power and long service life. [0003] The liquid injection of lithium ion batteries has always been the core technical link of battery production. In the prior art, the liquid injection equipment for the lithium ion battery injection process has many and complex processes. After the liquid injection is completed, the lithium ion battery needs to stand still to make the electrolyte Absorbed into the battery, some lithium-ion batteries require secondary injection due to insufficient electrolyte, which prolongs the manufacturing cycle of lithium-ion batt...

[0003] The liquid injection of lithium-ion batteries has always been the core technical link of battery production. In the existing technology, the liquid injection equipment for lithium-ion batteries has many procedures and complicated processes. After the liquid injection is completed, the lithium-ion batteries need to stand still to make the electrolyte Absorbed into the battery, some lithium-ion batteries need secondary injection due to insufficient electrolyte, which prolongs the manufacturing cycle of lithium-ion batteries and greatly increases the production cost of lithium-ion batteries
