Automated inspection equipment offers high accuracy, high efficiency, and 24/7 operation that human inspectors cannot match. Automatic inspection equipment utilizes CCD industrial cameras to replace most manual visual inspections, finding widespread applications in inspecting appearance, dimensions, defects, scratches, oil stains, blemishes, and other imperfections.
Compared to manual inspection, automated visual inspection equipment offers the following advantages:
1. High efficiency and high precision
Automated visual inspection equipment can quickly photograph, locate, track, and analyze products. For example, high-speed inspection equipment for precision small metal parts can use 12 sets of 5-megapixel camera lenses simultaneously, achieving an accuracy of up to 0.007mm and a detection speed of up to 4000 pieces/hour. Some inspection equipment uses high-pixel lenses, achieving micron-level detection accuracy, while the naked eye can only detect down to the millimeter level, let alone someone with severe myopia like me, whose vision is blurry without glasses.
2. Objectivity and high repeatability
Humans have subjective judgment; the quality of a product is judged based on subjective human perception. Automated visual inspection equipment, however, operates based on a fixed program, repeatedly performing the same action. In other words, humans are subjective, while machines are objective. The machine's judgment is objective; it doesn't have emotions and won't be affected by mood swings, thus maintaining consistent quality and accuracy. It also doesn't experience visual fatigue and can work continuously for extended periods.
3. Low cost
Factories incur high costs in recruiting, training, and providing salaries and benefits for inspection workers. Personnel turnover further increases these costs. One inspection machine is equivalent to several human workers. It doesn't require training, there's no concern about personnel turnover, it doesn't need breaks, and it can work continuously, offering a significant advantage in inspection efficiency compared to manual inspection.
