The difference between visual inspection machine and manual inspection
Visual inspection machine
The accuracy of visual inspection machine can reach a very high level. It is detected through precise optical imaging system and advanced algorithm, and can identify tiny size deviation, defects, etc. For example, when detecting the spacing of electronic chip pins, it can be accurate to micron level. For some tiny scratches or pits, as long as their size exceeds the set threshold, they can be accurately detected.
Moreover, its accuracy can remain stable during long-term work, and will not fluctuate due to environmental changes or self-fatigue.
Manual inspection
The accuracy of manual inspection is limited by the physiological limit of the human eye. It is difficult for the human eye to detect some extremely tiny defects, such as scratches less than 0.1mm or part differences with size deviations within a small range.
The state of the inspector (such as fatigue, mood, attention, etc.) will have a great impact on the detection accuracy. Long-term inspection work will cause fatigue of the inspector, resulting in reduced detection accuracy, and prone to missed detection or misjudgment.
Working Principle of DenT- Dounble glass table visual inspection machine
The system consists of two workstations which contains inner side and outer side, each with six 2-megapixel or 5-megapixel color cameras distributed at a 60-degree Angle. Each camera uses a low-distortion lens. In addition, the system also features two sets of color lighting systems distributed above and below. It has an independently digitally adjustable lighting system to abnormalities on the basis of detecting the inner and outer defects.
Equipment Advantages of DenT- Double glass table visual inspection machine
Dent is an optical inspection device for dimensional and surface defected detection of round and shaped parts. It can detect rubber, plastic, PTFT and other materials with high precision within its detection range. These materials are tested for defects at a series of inspection using high-precision industrial cameras. The images obtained by the camera are transferred to the computer managed by the real-time system for image processing without data loss and interference: the user can interact with the operating system in a simple and intuitive way through the operating interface. The detection system is stable, reliable, efficient and high-speed.
