Abstract

The invention relates to the technical field of lithium battery processing, in particular to a battery cell turnover mechanism for lithium battery production. A turnover mechanism and a pushing mechanism arranged in the side of the turnover mechanism and used for pushing a battery cell are included , the turnover mechanism comprises a springback roller type assembly used for clamping the battery cell, a pressing air cylinder assembly used for driving the springback roller type assembly to clamp the battery cell and a turnover driving air cylinder used for driving the springback roller type assembly to turn over; the pushing mechanism comprises a first-stage pushing air cylinder, a second-stage pushing air cylinder and a pushing air cylinder. According to the invention, the turnover mechanism is arranged, and through the 180-degree turnover mechanism, the problem of collapse of battery cell tabs due to the gravity of a first circle of the battery cell diaphragm is solved, and the battery cell yield is improved; and meanwhile, a turnover platform adopts an automatic rebound low-resistance roller structure design, so that when the battery cell passes through the turnover platform, theeffect of preventing friction scratch on the surface of the battery cell is achieved.

Description

technical field [0001] The invention relates to the technical field of lithium battery processing, in particular to a cell turning mechanism for lithium battery production. Background technique [0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution. The difference between lithium battery and lithium ion battery is that the former is a primary battery and the latter is a rechargeable battery. Due to the very active chemical properties of lithium metal, 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 day by day, which puts forward high requirements on power supply, and lithium batteries have entered a large-scale practical stage. [0003] At present, in the lithium b...
