Burr detection mechanism

Abstract

The invention relates to a burr detection mechanism, which comprises a base plate and a positioning mechanism, wherein the base plate is arranged on a frame body, the positioning mechanism is arranged on one side of the base plate, a vertical camera and two oblique cameras which are obliquely arranged are arranged on the base plate, the two oblique cameras are symmetrically arranged on the two sides of the vertical camera, lens extension lines of the vertical camera and the two oblique cameras are intersected to be an intersection point, and the intersection point is arranged on the positioning mechanism. The vertical camera and the two oblique cameras which are arranged on a detection platform can detect workpieces from different angles, and are extremely comprehensive in detection surfaces without dead angles. The positioning mechanism can steadily and accurately fix the workpieces on the positioning mechanism by matching pushing blocks and positioning columns, the positions of the workpieces and the positions of camera lenses are relatively extremely accurate at the moment, and comparison between the shooting images of the cameras and standard images are relatively accurate, thereby improving detection efficiency and quality.

Description

technical field [0001] The invention relates to a detection device for fine workpiece surface, in particular to a burr detection mechanism. Background technique [0002] Electronic products, especially mobile phones or tablet computers, are usually made of metal casings. During the processing of such metal casing workpieces, burrs are usually generated on the surface. Larger burrs on the surface can be detected by the naked eye. Differentiation can be processed, but due to certain structures of the shell, burrs are at the corners, etc., making it difficult to observe and handle with the naked eye. In addition, due to the small size of the burrs, it is difficult to identify with the naked eye, and special settings are required. , such as CCD camera for identification and detection, and further through the equipment of the prior art, due to the angle, the burr is not easy to detect, and it needs multi-angle simultaneous detection to be realized. In addition, it is necessary t...
