Advantages of industrial computer all-in-one in machine vision system
Machine vision is a comprehensive technology, including image processing, mechanical engineering technology, control, electric light source lighting, optical imaging, sensors, analog and digital video technology, computer software and hardware technology, mainly composed of industrial cameras, light sources, industrial computer integrated machines and Corresponding image analysis software system composition.
The working principle of machine vision is very simple. It can be regarded as a single-function industrial robot. It uses a camera to obtain the image of the inspected object, and the special light source enables the characteristics of the inspected object to be enhanced in the image, such as size features, surface defect features, etc. The images with clear characteristics are transmitted to the industrial computer all-in-one at high speed, and the characteristics are calculated by professional image analysis and processing software. According to the calculation results, the industrial computer all-in-one can control the actuator to perform classification, rejection, alarm and other actions. If compared with humans, then cameras are like human eyes, industrial computer integrated machines are like human brains, and software is like human thoughts, and then the actuators are like human hands and feet. The machine vision system is like a person with fast thinking, agile movements, and tirelessness. Compared with manual detection, it has the following advantages:
1. Fast speed: The industrial computer integrated machine has fast calculation speed. It can fully inspect the surface of strip steel moving at 1000m per minute with an accuracy of 0.1mm, and it can also accurately measure the size of complex parts at a speed of thousands of pieces per minute.
2. Stable quality: The biggest disadvantage of manual inspection is that the quality is unstable. Industrial computer all-in-one has the characteristics of reliability and stability, which can ensure that the set tasks work uninterrupted for 24 hours, and ensure that there are no omissions in product inspection.
3. Not restricted by the environment: Industrial computer all-in-ones can provide different shapes, processors, storage, I/0 configurations and expansion slots according to the actual needs of machine vision, and can work normally in small spaces, high temperatures and other environments.
4. High precision: For the quality inspection of very small electronic components, connectors, etc., workers often need to resort to 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.
With the rapid development of industrial computer all-in-one technology, relying on the strong support of industrial computer all-in-ones, machine vision technology is increasingly being applied to online inspections in industrial production to achieve rapid and complete inspections of product quality. Achieve zero defects in product quality. At present, machine vision is mainly used in surface quality inspection, size measurement, target positioning, target recognition, target comparison, etc. Involved areas include electronics, lasers, automobiles, metallurgy, food and beverage, pharmaceuticals, printing, packaging, parts assembly, etc.
