Abstract

The invention relates to an automatic light source adjusting device for a machine vision system. The light source device comprises a sleeve fixing module, a support ring sliding module and a control module; the sleeve fixing module is provided with a linear motor stator part, and is fixed in a groove in the inner wall of a sleeve; the support ring sliding module includes a support ring and an LED lamp module; a linear motor mover part is fixed in a groove in the outer wall of a support ring; a servo motor and a speed reducer integrated module are provided and connected to a characteristic sinking groove and an LED lamp module tail hole; the control module controls a linear motor to drive a mover module to move on a stator module so as to drive the support ring sliding module to move to realize adjustment of a light source distance; and the control module controls the servo motor and the speed reducer integrated module to work so as to drive the LED lamp module to rotate to realize adjustment of a light source angle. The device satisfies application of one light source to different vision detecting systems, can adjust optimal illuminating distance and angle, and improves the illuminating uniformity and the lighting quality.

Description

[0001] The invention relates to the lighting field, in particular to an automatic adjustment light source lighting device for a machine vision system. Background technique [0002] The machine vision system converts the captured target into an image signal through image acquisition hardware (camera, lens, light source, etc.), and transmits it to a dedicated image processing system. The image processing system extracts the features of the target according to information such as pixel brightness and color distribution, and makes corresponding judgments, and then controls the on-site equipment according to the results. The final realization is to make the machine have human-like visual functions, so as to realize various detection, judgment, identification, measurement and other functions. [0003] Machine vision system has the characteristics of high efficiency, high flexibility and high automation. In the process of mass production, if artificial vision is used to check produc...
