Abstract: Disclosed are a pole piece labeling control method and device, electronic equipment, and a storage medium. The method includes: acquiring a pole piece image, including a pole piece mark hole image, of a target pole piece; determining a defect detection result according to the pole piece image; determining a first distance according to the pole piece mark hole image; determining a second distance according to the first distance; determining a labeling delay of the target pole piece according to the second distance; and controlling the labeling of the target pole piece according to the labeling delay and the defect detection result. The real-time position of the pole piece transferred on a compression roller is identified through the pole piece mark hole image, so that the accuracy of the labeling delay is improved, and the labeling position based on the labeling delay is more accurate.

Abstract: A detection method includes acquiring a first shot image of a long-side weld of a battery cell under detection by using a first structured light camera on a long side of the battery cell under detection, acquiring a second shot image of a short-side weld of the battery cell under detection by using a second structured light camera on the short side of the battery cell under detection, detecting a defect of the long-side weld of the battery cell under detection based on the first shot image, and detecting a defect of the short-side weld of the battery cell under detection based on the second shot image.
