With the rapid growth of industrial production, more and more companies are gradually moving towards the international market. In the highly competitive international market, low cost and high quality are the keys to determining product life. How to improve product quality and how to achieve zero defects have gradually attracted people's attention. For various products, the methods of ensuring quality are also different. Let us discuss the application of "machine vision technology" in this field.

Machine vision is the "eye" of industrial automation, mainly composed of industrial cameras, light sources, industrial computers and corresponding image analysis software systems.
The working principle of machine vision is very simple. It is very similar to a single-function industrial robot. For example, it uses a camera to obtain the image of the detected object, and the special light source enables the features of the detected object to be enhanced in the image, such as size features, surface defects Features etc.
The images with clear characteristics are transmitted to the industrial computer at a high speed, and the characteristics are calculated by professional image analysis and processing software. According to the calculation results, the industrial computer can control the actuator to perform classification, rejection, alarm and other actions. If you compare it with humans, then cameras are like human eyes, industrial computers are like human brains, and software is like human thoughts. Then the actuators are like human hands and feet. In fact, the machine vision system is like a person with fast thinking, quick actions, and tirelessness.

Advantages of industrial computer：
Take IPC-6041 industrial computer as an example
Fast speed: The surface of strip steel moving at 1000m per minute can be fully inspected with an accuracy of 0.1mm, and the size of complex parts can be precisely measured and collected at a speed of thousands of pieces per minute.
Stable quality: The biggest drawback of manual inspection is that the quality is unstable, while the Yanhong industrial computer does not. The Yanhong industrial computer has the characteristics of reliability and stability. The machine vision can work uninterrupted for 24 hours with the set tasks, and ensure that the product inspection is complete.
Unrestricted by the environment: Humans cannot work in environments such as high temperatures and small spaces in industrial production, but machine vision is not restricted.

High precision: For the quality inspection of very small electronic components, connectors, etc., workers often need to use microscopes and other means, and the efficiency is low, while machine vision can quickly measure any small size with the help of high magnification lenses.
