Surface defect detection equipment to detect product surface defects belongs to a kind of machine vision detection technology, the use of computer vision to simulate the function of human vision, from the concrete object image acquisition processing, calculation, and finally the actual detection, control and application. The accuracy of its detection will directly affect the final quality of the product. Because the use of artificial detection method has long been unable to meet the needs of production and modern manufacturing process, and the use of machine vision detection to overcome this point, the wide application of surface defect detection system promotes the high quality production of factory products and the development of intelligent automation in manufacturing industry.
CCD visual detection of surface defects adopts imported high-resolution camera, extract surface wrinkles, notch, cracking, dropping, adhesive, bubble, leakage of foil and other defects. And output the corresponding qualified/unqualified signal prompt, which is convenient for the next station to deal with the defective products.
Main functions of surface defect visual detection equipment: 1. Automatic image positioning; 2. 2. Detect defects such as fold, notch, cracking, material dropping, adhesive, bubble and foil leakage on the surface of the product 3. If the product is qualified, OK signal will be given. If the product is unqualified, output NG signal or send alarm signal 4. Can automatically save unqualified requirements of the image 5. Can save the detection data for historical data query
Operating principle of surface defect visual detection equipment: the product passes through the visual detection system in the same direction; A CCD camera is used to scan the product line at the same time. After the product is in place, the photoelectric eye output trigger signal is transmitted to the camera to trigger shooting; The software makes processing judgment and outputs OK/NG signal; The equipment shall be processed accordingly at the next station.
Technical features of surface defect visual detection equipment: 1. The operation interface is clear, simple and easy, and the detection can be performed automatically with simple setting; 2. 2. The detection software and algorithm are fully independently developed, and the system is highly targeted; 3. Local detection can be carried out selectively to improve the flexibility of detection; 4. Professional light source design, imaging clear and uniform, to ensure the completion of detection tasks; 5. Easy installation; Compact structure, easy to operate, maintain and expand; 6. High reliability, stable operation, suitable for various field operating conditions. 7. Based on PC platform, the system is extensible.
The principle of surface defect visual detection equipment is introduced: when the image is positioned well, the surface defects are extracted according to whether there are wrinkles, notch, cracking, material dropping, sticky material, bubble, foil leakage and other defects on the surface of the pole plate in the detection area exceeding the set gray difference value, and the location of the defect and the size of the defect are indicated. Output corresponding detection signal.
