The appearance defect detection system is mainly used to quickly identify the appearance defects of samples, such as pits, cracks, warps, gaps, stains, sand, burrs, bubbles, uneven color, etc. The tested samples can be transparent or opaque. Next, we will take you through the details of what appearance defect detection is.
In the past, product appearance detection is generally identified by the naked eye, so human factors may lead to inconsistent measurement standards, and long-term detection due to visual fatigue will cause misjudgment. With the deep cooperation of computer technology and optical, mechanical, electrical and other technologies, it has the characteristics of rapid and accurate detection.
If the local physical or chemical properties of the product appearance and other areas are different, the appearance and function of the product will cause a great impact, such as scratches, spots, holes on the metal surface, paper surface color difference, indentation, glass and other non-metallic surface inclusion, damage, stains and so on. Surface defects not only affect the beauty and comfort of products, but also bring adverse effects on their performance. Therefore, manufacturers attach great importance to the detection of surface defects of products in order to find them in time, so as to effectively control the quality of products. They can also analyze some problems existing in the production process according to the detection results, so as to eliminate or reduce the occurrence of defects. At the same time to prevent potential trade disputes, maintain the honor of the enterprise.
Optical detection technology through the light source system, image acquisition system, image processing system, mechanical action system, data statistics management system, etc. to the product to be tested, the characteristics of product surface defects appear, so that the camera can take photos. Common light sources are halogen lamps, fluorescent lamps and light emitting diodes (leds). LED light source has been widely used for its advantages of small size, low power consumption, fast response speed, good luminous monochrome, high reliability, uniform light stability, easy integration and so on.
