Automatic packaging method of lithium battery

Abstract

The invention relates to the technical field of battery processing, and discloses an automatic packaging method of a lithium battery. The automatic packaging method comprises a base, wherein a rotating oil cylinder is fixedly mounted in the middle of the top of the base, a fixed cylinder is fixedly mounted at the top of the rotating oil cylinder, a supporting frame is fixedly mounted at the periphery of the top of the base, a limiting disc is fixedly mounted in the middle of the supporting frame, a fixing disc is fixedly mounted at the top of the supporting frame, and pressing devices are movably clamped in the fixing disc. According to the automatic packaging method of the lithium battery, the purpose of a good packaging effect is achieved by arranging a hydraulic rod, the pressing devices, the fixing disc and the like, the eight pressing devices are arranged at the bottom of the hydraulic rod, and the pressing rods of the pressing devices are different at a certain height. When a shell and a top cover need to be packaged, in cooperation with intermittent rotation of the upper rotating oil cylinder, the eight pressing devices sequentially press the upper rotating oil cylinder fromshallow to deep at the moment, and on the one hand, the control is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of battery processing, in particular to an automatic packaging method for lithium batteries. Background technique [0002] Lithium batteries use lithium metal or lithium alloy as the anode material and use non-aqueous electrolyte solutions. The difference between lithium batteries and lithium-ion batteries is that the former is a primary battery and the latter is a rechargeable battery. Due to the chemical characteristics of lithium metal are very Lively, the processing, storage, and use of lithium metal have very high environmental requirements, so lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment is increasing, which puts forward very high demands on the power supply. Lithium batteries have entered a large-scale practical stage. [0003] As the demand for lithium batteries becomes more and more v...

Problems solved by technology

[0003] As the demand for lithium batteries becomes more and more vigorous, its processing also needs to be automated. There are many automatic processing steps for lithium batteries, and packaging is an important step. There are certain problems: the existing equipment for the packaging of lithium batteries, especially the packaging of the top cover and the shell, basically uses a stamping equipment for stamping processing, but simply adjusts the frequency and degree of stamping, which is still very difficult. It is easy to damage and twist the top of the shell by pressing, and it is easy to leak the material when it is squeezed later
