The reasonable use of machine vision light source can better present the product in the form of pictures through different color temperature and chromatography, and can make the machine compare the product object with the picture, so as to accurately detect the product quality. So, in the process of using the top machine vision light source, what common problems perplex us? Here are the answers one by one.



Common problems of machine vision light source



1. What are the light source controllers?



The controller of machine vision light source can make it better for the detection of objects, so that the detection of products can obtain the best effect. In general, the light source controller has the following types: analog controller, digital controller and high-power analog controller, in addition to linear light source special analog and digital controller. There are some functional differences between each controller, so we should choose according to the actual needs.



2. What light source should be used for rough or reflective objects?



If the surface of the object to be tested is rough, the coaxial light source and the visual light source with diffuse reflection effect should be used when selecting the machine vision light source, so as to make the illumination of the object surface more uniform, so as to make the imaging effect more clear; if the surface can reflect the object needs to be detected, then the light field light source should be used, which can avoid The surface of the measured object is reflected by light.



3. How to choose the shape and size of the light source?



Machine vision light source is mainly divided into three forms: square, strip and round. Generally, the light source consistent with the shape of the object under test should be selected, but the final selection result should be based on the test effect. At the same time, it should be noted that when selecting the size of light source, it is necessary to ensure that the light source is uniform in the whole inspection field, and it is better to be slightly larger than the field of vision.



The above is the use of machine vision light source in a few common questions and their answers. I hope that through the answers to these common questions, we can better understand the first-class machine vision light source, because only when we fully understand the various functions and adaptability of machine vision light source as well as the scope of application, can we make better use of it to carry out high-efficiency detection of products.
