A visual detection light source and tab detection equipment are described. The visual detection light source is configured to irradiate a side face of a tab portion, and includes a main light source and a supplementary light source; the main light source and the supplementary light source are arc-shaped light sources, the main light source and the supplementary light source are disposed concentrically, and the main light source is disposed outside the supplementary light source; the main light source is configured to irradiate the side face of the tab portion at an inclined irradiation angle; and the supplementary light source is configured to vertically irradiate the side face of the tab portion.

Visual detection light source and tab detection equipment

This application discloses a tab detection mechanism and a tab detection device. The tab detection mechanism may be configured to detect a tab portion on an electrode core. The tab detection mechanism may include a visual camera; a prism disposed below the visual camera and configured to reflect light on a side surface of the tab portion to the visual camera; and a first driver, connected to the visual camera and configured to drive the visual camera to move in a vertical direction. The visual camera is capable of shooting a plurality of images while moving.

Tab detection mechanism and tab detection device

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.
