Surface defect detection mechanism for button type lithium-manganese battery

The utility model relates to the technical field of button type lithium-manganese battery detection, in particular to a button type lithium-manganese battery surface defect detection mechanism which comprises a working table, a detection mechanism body used for detecting button type lithium-manganese battery surface defects is installed above the working table, and the detection mechanism body comprises a first motor. Through the arrangement of the first motor, the threaded rod, the sliding rod, the U-shaped moving plate, the first electric push rod, the camera and the display screen, the camera is pushed to move through the first electric push rod, after the camera moves to a proper position, the first motor drives the threaded rod to rotate, the threaded rod drives the U-shaped moving plate to move, and the U-shaped moving plate drives the camera to move; the camera moves to inspect the button type lithium-manganese battery, and when the camera works, an image is projected on the display screen, so that the
