Machine vision automatic screening is the use of machines instead of human eyes to make a variety of measurements and judgments. On the production line, human beings making such measurements and judgments will cause errors and errors due to fatigue, differences between individuals, etc., but the machine will carry on tirelessly and steadily. Generally speaking, machine vision system includes lighting system, lens, camera system and image processing system.
Machine vision automatic screening machine from objects/bar code identification, product detection, appearance size measurement to mechanical arm/transmission equipment positioning, are machine vision technology can play the stage, so its application range is very wide, industry application field is more to dazzling.
Detection is one of the main application of machine vision automatic screening machine industry, almost all products need to test, the application of machine vision detection equipment in image detection is also very wide, in fact, sorting application is based on the object identification, detection after a link, through the image processing, machine vision systems to implement sorting.
Machine vision automatic screening and detection can improve the detection accuracy and production efficiency, in the case of a large number of products, the detection accuracy is not high, manual detection efficiency is low, and the accuracy is far less than the machine, so more and more machine vision detection equipment began to replace manual. Such as area, length, quantity, position, and then according to the preset allowable degree and other conditions output results, including size, Angle, number, qualified/unqualified, yes/no, CCD detection equipment, automatic identification function.
Application scope of automatic screening and detection:
Precision screws, precision nuts, buttons, metal stamping parts, probe connectors, electronic components, plastic products (such as O-ring, Y-ring, flat washer), applicable to a wide range of industries.
Main workflow of visual automatic screening:
1. Sensor signals are sent to the camera.
2. The camera starts taking pictures through the switch.
3. The acquired image is sent to the computer software for analysis and judgment.
4. Send the software analysis results to the machine and equipment.
With the increasing maturity of the related basic technology, many manufacturing enterprises at home and abroad use machine vision technology for positioning, measurement, identification and defect detection and other functions, in order to greatly improve the automatic production efficiency, reduce production costs, reduce production risks.
