Product appearance defect detection device based on machine vision

Abstract

The invention relates to the technical field of product appearance defect detection devices, and discloses a product appearance defect detection device based on machine vision, the product appearance defect detection device comprises a bottom frame, the inner wall of the top of the bottom frame is provided with a rotation detection assembly, and the top of the bottom frame is provided with an article placement assembly. After the visual camera rotates by 360 degrees, the four faces of the object are shot, the mounting support rotates in the same direction to push the inner gear ring to rotate by 30 degrees again, at the moment, the inner gear ring rotates to drive the third gear to rotate, and the third gear rotates to drive the first gear and the second gear to rotate; the rotating shaft I, the rotating shaft II, the outer rubber sleeve I and the outer rubber sleeve II are rotated to drive the article to rotate, at the moment, the top surface and the bottom surface of the article are rotated to the side surfaces, then the mounting bracket is reversely rotated by 30 degrees, and then the mounting bracket is rotated by 180 degrees to photograph and detect the undetected surfaces of the article; therefore, the problems that the surface of the object is easily damaged and the detection time is relatively long when the existing defect detection device is used for detecting the cylindrical object are solved.
