Pole piece winding coverage detection method and device

The invention provides a pole piece winding coverage detection method and device, and the method comprises the steps: respectively collecting an image of a first side surface of a negative pole pieceand an image of a positive pole piece through a first image collection device after the winding of the negative pole piece and during the winding of the positive pole piece, and obtaining a head sideline of the head paste coating of the first side surface of the negative pole piece and a head side line of the head paste coating of the positive pole piece, and determining a first coverage length.The pole piece image is acquired and processed through the image acquisition device and the image processing device to obtain the head covering length of the roll core, and compared with the prior artthat the head covering length can only be obtained through destructive disassembly, the detection effect is better. 本发明提供一种极片卷绕覆盖检测方法及设备，其中，所述方法包括：通过第一图像采集装置在所述负极极片入卷后和所述正极极片入卷时分别采集所述负极极片的第一侧面的图像和所述正极极片的图像，以获取所述负极极片的第一侧面的头部涂膏头部
