Industrial automation machine vision defect detection to identify a variety of appearance defects in the product

Industrial enterprise product manufacturing development process, due to a variety of factors affecting the analysis led to the company's product market some defects defective problems, such as fasteners screws surface quality defects contain more than a dozen kinds of such as; no teeth, rotten teeth, bad teeth, oblique teeth, rubbing the teeth bad, teeth within the burr, lack of material, blocked holes, vision system companiesand other defects management problems.

Machine vision inspection technology can quickly detect product surface defects, has the advantages of fast and accurate. Surface defects inspection uses advanced machine vision inspection technology to detect surface cracks, pits, scratches, color differences, defects and other defects. Machine vision inspection has four main functions in the manufacturing production line, namely measurement, detection, localization and identification, but the traditional manual inspection methods are different due to different perceptions of each individual. The quality of their products cannot be guaranteed consistency and machine vision can be repeated 24 hours a day to avoid subjective factors such as judgment.

Machine vision defect detection technology can automatically complete the synchronization of the workpiece and the camera to obtain images, automatic detection of product surface defects such as scratches, deformation, pits, foreign objects, off-color cracks and so on. Machine vision defect detection technology can select the type of defects to be detected according to the need, the vision system can independently set the size of the defects according to the need, automated inspection system machine vision defect detection technology can quickly locate defects in defective products defect location. Machine vision defect detection technology can automatically store defective images, history query, automatic counting (good, bad, total, etc.). The machine vision defect detection technology can automatically store the defective images for historical inquiry, automatic counting (good products, defective products, total number, etc.), provide acoustic and visual alarms in case of abnormality and control the equipment to stop. Machine vision defect detection technology can be systematically self-learning function, the learning process is simple to operate.

Why use machine vision inspection system in industrial automation?

Machine Vision Automatic Surface Defect Inspection System: The system consists of high-speed CCD camera system, synchronized imaging light source system, storage and graphic analysis server system, automatic visual inspection system and software that automatically adjusts the depth of field, which can realize continuous automatic detection, classification, rating and recording of 2D+3D surface defects. It can quickly and effectively detect a variety of defects, such as cracks, pits, folds, indentations, scars, etc.. It can adapt to the complex modern industrial manufacturing production environment, and can perfectly replace visual inspection to reach the level of unmanned production.

Machine vision technology inspection management system has a clear advantage in terms of accuracy. In accuracy and repeatability, due to the human eye has physical teaching conditions constraints, even if the human eye relies on magnifying glasses or microscopes to detect students to improve, the machine will still be more comprehensive and accurate, because its accuracy requirements can be developed to reach one thousandth of an inch. Machines and equipment can accomplish the target detection research work in the same way the same enterprise product design over and over again without getting tired. In contrast, the human eye is slightly different each time a product is inspected, even if the product is not the same at all.

Speed and cost, the machine can detect products faster. Especially when it comes to detecting objects moving at high speeds, such as on a production line, machines can increase productivity. Because machines are faster than people, an automatic inspection machine can take on the tasks of several people. And the machine does not need to stop, will not get sick, can work continuously, which can greatly improve productivity. Another fatal flaw of human eye testing is the subjectivity that comes with emotion. The results can vary with the employee's emotions, but machines have no emotions, so the results are quite reliable.

Machine vision inspection systems can quickly acquire a large amount of information and are easy to automatically process and integrate design information and processing control information. Therefore, in the modern automated production process, machine vision inspection system is widely used in the monitoring of working conditions, finished product inspection and quality control. Machine vision inspection systems are characterized by improved production flexibility and automation.
