The invention discloses a machine vision-based automatic detection device for the base corner of a polymer soft package lithium battery. The device comprises an image acquisition module used for acquiring a first base corner image of the polymer soft package lithium battery, an image processing module which is connected with the image acquisition module and is used for preprocessing the first base corner image to obtain a second base corner image, a detection module which is connected with the image processing module and is used for carrying out base corner damage detection on the second base corner image to obtain a detection result, and a rejecting module which is connected with the detection module and is used for rejecting the polymer soft package lithium battery with the damaged base corner according to the detection result. Compared with a human eye identification method, the machine vision-based automatic detection device for the base corner of the polymer soft package lithium battery has the beneficial effects that the labor cost is saved, and the accuracy, the efficiency and the flexibility are very high.
Description
technical field [0001] The invention relates to the technical field of lithium battery detection, in particular to a machine vision-based automatic detection device for the bottom corner of a polymer soft-pack lithium battery. Background technique [0002] Polymer flexible packaging lithium batteries have the advantages of good safety performance, light weight, large capacity and small internal resistance. They are 40% lighter than steel-cased lithium batteries of the same capacity, 20% lighter than aluminum-cased batteries, and have a higher capacity than steel-cased batteries of the same size. 10-15% higher, 5-10% higher than aluminum shell batteries, and the minimum internal resistance can be less than 35mΩ, which greatly reduces the self-consumption of the battery. However, during the production process, cracks and damage to the bottom corner of lithium batteries in polymer flexible packaging are common. At present, the detection of cracks in the bottom corners of polym...
