Abstract

The invention provides film sampling equipment, which comprises a first film fixing device, a second film fixing device and a cutting device located between the first film fixing device and the second film fixing device, the cutting device comprises a driving device, a first pressing base and a second pressing base, the first pressing base and the second pressing base are in transmission connection with the driving device, and a cutter is arranged on the first pressing base; the driving device is used for driving the first pressing base and the second pressing base to be away from the non-working position or close to the working position, so that the cutter can be matched with the second pressing base to cut a film at the working position. According to the sampling equipment for the film, the to-be-cut film is fixed through the first film fixing device and the second film fixing device, the film does not need to be manually fixed and cut, and the safety of operation and use is improved; meanwhile, the automatic sampling can be achieved through the cutting device, so that the sampling steps are simplified, and therefore the film sampling equipment has the advantages of being safe, reliable and convenient to operate.

Description

technical field [0001] The present application belongs to the technical field of sampling equipment, and more specifically relates to membrane sampling equipment. Background technique [0002] As the "third pole" in the lithium-ion battery, the diaphragm plays the role of providing ion transmission channels, isolating the positive and negative electrodes, and preventing the internal short circuit of the battery during the charging and discharging process of the battery. It is crucial to ensure the electrical performance and safety performance of the battery. important. The parameter detection items of the separator for lithium batteries include the separator width, thickness, air permeability, puncture strength, heat shrinkage, tensile strength and tensile elongation, etc., and the parameter range directly affects the performance of the battery product. [0003] During production, most of the diaphragms used are products with a certain width after slitting, and the size is ...
