Abstract

The present invention discloses a device for detecting the straightness of an edge of a pole piece, which includes a pole piece conveying device and a pole piece edge detection mechanism. The pole piece conveying device passes through the pole piece edge detection mechanism. The pole piece edge detection device includes a plurality of groups of detection mark processing devices. The detection mark processing devices are arranged directly above or directly below the pole piece conveying device. The plurality of groups of detection mark processing devices are arranged side by side along the conveying direction of the pole piece conveying device. The pole piece conveying device conveys the pole piece into the pole piece edge detection mechanism in a segmented manner. The detection mark processing device is aligned with the side edge of the pole piece conveyed by the pole piece conveying device. The detection mark processing device detects the straightness of the side edge of the pole piece and marks the pole piece segment detected to be uneven. The pole piece edge straightness detection device of the present invention can automatically perform a full inspection on the pole piece. In addition, the present invention also discloses a battery cell winding production line.
