  • Publication number: 20240150149
    Abstract: Provided are an electrode plate wrinkling detection apparatus and cell production equipment, pertaining to the field of battery technologies. The electrode plate wrinkling detection apparatus includes an image detection mechanism and a moving mechanism. The moving mechanism is configured to drive the image detection mechanism to move on a winding machine within a region directly facing a cell and adjust a shooting angle of the image detection mechanism. The image detection mechanism includes an image capture device and a detection module that are interconnected. The image capture device is configured to photograph a cell to obtain a picture of the cell and transmit the picture of the cell to the detection module. The detection module is configured to examine the picture of the cell to detect presence of electrode plate wrinkling using a grayscale algorithm and output a detection result.
