The invention discloses a visual detection method and device for separator paper. The visual detection device for the separator paper comprises a PLC, a visual controller, a camera and a battery shifting mechanism, wherein the PLC is connected with the visual controller and the battery shifting mechanism, and the visual controller is connected with the camera; detection stations for detection of the battery separator paper and removal stations for removal of unqualified battery separator paper are arranged on the battery shifting mechanism, the camera is arranged above the detection stations of the battery shifting mechanism, the axis where shooting of the camera is conducted and the axis of each detection station intersect, and a light source is arranged at the front end of the camera. The visual detection device for the separator paper has the advantages that detection of the battery separator paper is achieved through an image processing method, the battery separator paper can be automatically detected, the detection effect is good, the detection accuracy is high, safety and reliability are high, the working efficiency is improved, the labor intensity is reduced, the structure is simple, and operation is convenient.
Description
technical field [0001] The invention relates to the technical field related to battery preparation, in particular to a visual inspection method and device for separator paper. Background technique [0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Batteries generally use materials containing lithium elements as electrodes, which are representatives of modern high-performance batteries. [0003] Diaphragm paper is also called polyethylene film, PE film. Its role in lithium-ion batteries is to separate th...
