The detection efficiency is low, and it is impossible to detect whether the battery membrane is bent, so it is impossible to analyze. It is impossible to accurately measure the length of the battery membrane only by naked eye observation or the use of traditional tools, which may cause the battery membrane to not match the size of the installation position. Therefore, a device for accurately detecting the length of the battery membrane is needed. Utility Model Content
