Abstract

The invention discloses a detection device for surface defects of a curved workpiece, which has a simple structure and is portable, and ensures the quality of collected images. The detection device includes a portable detection device mechanical structure, a miniature digital zoom microscope system, a light source system, an object stage, an embedded ARM software system and an LCD liquid crystal display, and the center of the top of the object stage is provided with an image acquisition window, so The above-mentioned stage is composed of upper and lower layers of metal panels, there is a sawtooth slot between the two metal panels, and a rotatable position adjustment knob is provided on the side of the metal panel of the above-mentioned stage.

Description

technical field [0001] The invention relates to a detection device for surface defects of curved surface workpieces, in particular to a detection device for surface defects of curved surface workpieces with simple structure and portable, which is coordinated with multiple angle light source illumination and the height and position of the light sources can be adjusted. Background technique [0002] With the progress of society and the development of science and technology, people have higher and higher requirements for product quality and craftsmanship. Due to the mass production of the factory assembly line, there will be some defects on the surface of the curved workpiece, such as scratches, spots, pits, inclusions, and cracks. At present, most of the inspections are performed by human eyes, which is inefficient. In response to this situation, a detection device for surface defects of curved workpieces can liberate human eyes, replace human eyes to observe workpieces and co...
