Liquid injection device for lithium battery production

Abstract

The invention discloses a liquid injection device for lithium battery production, belonging to the technical field of lithium battery production equipment, comprising a fixed bottom plate, a support frame is installed on both sides of the upper end of the fixed bottom plate, a top plate is connected to the upper end of the support frame, and a drive box is installed in the middle of the right end of the top plate , the upper end of the drive box is installed with a rotating cylinder, the lower end of the rotating cylinder is in contact with the lifting cylinder, and the middle part of the right end of the lifting cylinder is provided with a lifting groove, and a lifting block is installed inside the lifting groove, and the lifting block is fixed on the inner wall of the driving box. Liquid rod, the lower end of the liquid injection rod is connected to the liquid injection piston, the liquid injection cylinder is installed on the outside of the liquid injection piston, the rotating shaft is installed in the middle of the upper end of the rotating cylinder, the upper end of the rotating shaft passes through the drive box and is connected to the first pulley, the first pulley The right end is connected with a second pulley through a belt, and the lower end of the second pulley is connected with a transmission shaft. The present invention realizes the intermittent rotation of the rotary table, and at the same time realizes the liquid injection effect on the lithium battery on the rotary table, which not only ensures the liquid injection efficiency, but also improves the liquid injection quality.

Description

technical field [0001] The invention relates to the technical field of lithium battery production equipment, in particular to a liquid injection device for lithium battery production. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream now. [0003] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeabl...

Problems solved by technology

[0005] Chinese patent (notification number: CN108110204A) discloses a liquid injection device for lithium battery production, including a casing, a sealed door assembly, a battery casing delivery assembly, a liquid injection assembly, a vacuum pump, and an inlet and outlet. There are inlets and outlets on each surface, and the sealed door assembly is assembled inside the inlet and outlet. The sealed door assembly includes a sealed door panel, a groove, a moving groove, a pull rod and a positioning column. The battery case delivery assembly is installed inside the casing. Although this device ensures the liquid injection of lithium batteries to a certain extent, the liquid injection method is a single lifting and one-time injection of multiple lithium batteries. Once one of them is not adjusted properly, all lithium battery injections will fail. , therefore, further improvement is required
