Abstract

The invention relates to a battery diaphragm cutting and positioning device, in particular to a lithium ion battery diaphragm cutting and positioning device. The lithium ion battery diaphragm cuttingand positioning device provided by the invention is relatively high in safety, relatively high in efficiency and relatively high in percent of pass. The lithium ion battery diaphragm cutting and positioning device comprises a base and a working frame arranged in the middle of the base; a pulling mechanism arranged on the working frame; a sliding mechanism arranged on the working frame, and connected with the pulling mechanism; and a cutting mechanism arranged on the working frame, and matched with the sliding mechanism. Through the design of the pulling mechanism, the sliding mechanism and thecutting mechanism, the lithium battery diaphragm is automatically cut, people do not need to manually cut the lithium battery diaphragm, through the design of the discharging mechanism and the correcting mechanism, the cut lithium battery is automatically discharged, and the lithium battery is more accurately cut.

Description

technical field [0001] The invention relates to a battery diaphragm cutting and positioning device, in particular to a lithium ion battery diaphragm cutting and positioning device. Background technique [0002] Lithium batteries have high power endurance, among which lithium iron phosphate batteries for electric vehicles can charge and discharge at 15-30C, which is convenient for high-intensity start-up acceleration. [0003] At present, when people cut the lithium battery diaphragm, people need to manually open the lithium battery and cut the lithium battery diaphragm manually. During the cutting process, it is easy for people to cut their own hands, and the visual cutting length is not accurate, so it is easy to cut. Offset, so that the product is scrapped, the qualified rate of the product is not high, and the efficiency of manual cutting is low. [0004] In the prior art, the patent application No. CN110197885A discloses a lithium battery diaphragm cutting device, inclu...
