Machine vision light source device with light spot shape controllable and implementing method thereof

Abstract

The invention discloses a machine vision light source device with the light spot shape controllable and an implementing method thereof. The machine vision light source device comprises a bottom plate, a shell, moving components, LED modules and a single chip microcomputer. An arc rail is arranged on the bottom plate. The moving components comprise a large inner gear, small gears, small motors, sliding blocks and sliding block rails, wherein the large inner gear is matched with the small gears. The large inner gear is fixed to the shell. The small gears are fixed to the output ends of the corresponding small motors. The small motors are fixed to the corresponding sliding blocks and further connected with the single chip microcomputer. The sliding blocks slide on the sliding block rails. The LED modules are located on the arc rail and connected with the corresponding sliding blocks. The small gears, the small motors, the sliding blocks and the sliding block rails of the moving components and the LED modules are distributed in multiple sets on the round array around the center of the bottom plate. The machine vision light source device has the advantages of being high in adaptability, convenient and high in detection efficiency, and can be widely applied to the optical field.

Description

technical field [0001] The invention relates to the field of optics, in particular to a machine vision light source device with controllable spot shape and its realization method. Background technique [0002] Machine vision technology is an interdisciplinary subject involving many fields. Machine vision is the use of machines instead of human eyes for measurement and judgment. The machine vision system refers to collecting the image signal of the detection target through the image capture device, and then sending it to a dedicated image processing system to obtain the shape information of the detection target, and convert it into the digital signal we need according to the pixel distribution, brightness, color and other information . Because machine vision is detected and judged by machines, it is often used in product quality inspections in mass production processes, dangerous environments that are not suitable for humans, or occasions where human vision is difficult to ...

AI Technical Summary

Problems solved by technology

If a circular spot with a uniform area and limited area is used to illuminate a non-circular part, it will often lead to uneven illumination on the edge of the part and similar features (the same kind of features are generally arranged according to the shape of the part), so that the captured image will pass through the image. After processing, due to the uneven illumination of features in the image, the edge of the part and similar features will appear splitting, making it impossible to extract the required information

[0004] To sum up, the current machine vision lighting source spot shape is fixed, it is difficult to meet the detection requirements of parts with different shapes, the applicability is not wide, it is not convenient enough, and the detection efficiency is low
