Classification:
360 ° light source
The utility model relates to a 360 ° light source surrounding irradiation type line light source structure for machine vision inspection, which comprises a ring-shaped mounting bracket and a plurality of word line light sources fixedly installed on the ring-shaped mounting bracket. The irradiation direction of the word line light sources faces the workpiece to be detected located inside the ring-shaped mounting bracket, and the word line is arranged around the workpiece to be detected. Compared with the prior art, the utility model has the following advantages and beneficial effects: when the light source of the utility model is used to irradiate the workpiece to be detected, the convergent light emitted from different angles shines on the surface of the workpiece to be detected. Since the light planes of the light sources are parallel or nearly parallel to each other, and the irradiation height is the same or nearly the same, a circle of bright light is formed on the surface of the object to be detected, the specified range of the object to be detected is illuminated in all directions of 360 °, and only the local height range is illuminated, so as to avoid the scattered light from being irradiated to other positions to interfere with the detection.
