Rotary disc type liquid-filling machine for battery

Abstract

The invention relates to a rotating disk type battery liquid injection machine. The invention is characterized in that four symmetrically distributed through holes are formed on a rotating disk, a plurality of liquid injection tubes are fixed regularly side by side through a fixing plate, the fixing plate is embedded in the through holes of the rotating disk, a positioning plate is arranged at the upper part of a battery fixture, a plurality of liquid injection needles are fixed on the positioning plate, a bottom plate and a plurality of bases are arranged at the lower part of the battery fixture, elastic parts are arranged below the bases, a vacuum box and a pressing plate are connected with an actuating cylinder, seal rings are arranged on the vacuum box and a pressing plate, and a decollator controls the rotating disk to rotate 90 degrees every time. The rotating disk type battery liquid injection machine has the advantages that a plurality of working procedures are carried out simultaneously, therefore, the working efficiency is greatly enhanced, the fluid injection accuracy is guaranteed, the operation is simple, and the performance is stable.

Description

technical field [0001] The invention relates to a battery liquid injection machine, in particular to a turntable type battery liquid injection machine. Background technique [0002] At present, there are semi-automatic turntable type liquid injection machines for lithium-ion battery injection in China, that is, there is a circle of liquid injection device on the turntable, and there is a battery clamping tool below. By clamping the batteries one by one, the turntable rotates to work. The working efficiency of the method is too low, and the high rotation frequency of the turntable makes the machine easy to be damaged and repaired frequently. There is also a back suction type liquid injection, that is, the battery to be injected is put into a vacuum container, and then evacuated, the vacuum in the vacuum container is used to inhale the electrolyte, and then the electrolyte is inhaled into the battery shell alternately with a vacuum and a desiccator. This kind of battery liqui...

Problems solved by technology

[0002] At present, there are semi-automatic turntable liquid injection machines for lithium-ion battery injection in China, that is, there is a circle of liquid injection devices on the turntable, and there is a battery clamping tool below. By clamping the batteries one by one, the turntable rotates and works. This kind of liquid injection is used. The working efficiency of the method is too low, and the high rotation frequency of the turntable makes the machine easy to be damaged, and the maintenance times are many

There is also a suction-type liquid injection, that is, the battery to be injected is put into a vacuum container, and then vacuumed, the vacuum in the vacuum container is used to inhale the electrolyte, and then the electrolyte is sucked into the battery case alternately with a vacuum and a dryer. This kind of battery liquid injection machine has low efficiency of liquid injection and slow absorption, and a large amount of electrolyte remains in the battery shell, resulting in waste of resources and corrosion of the shell, and the electrolyte is in contact with air for a long time and is easy to absorb water.
