CCD vision inspection equipment uses machine vision technology and detects based on CCD industrial camera. According to the system control, the error is not big, and the detection efficiency is high, which can exceed 400- 1200 per minute. Some small parts may exceed the speed of thousands or even hundreds of thousands.
Second, the quantum power is high.
This is its greatest advantage. The average quantum power of CCD visual inspection is 30% to 50%, and the highest quantum power can be as high as 90%, which is about 100 times that of ordinary film.
Third, save labor costs and be able to carry out highly repetitive work.
CCD vision inspection can work stably for a long time, but it is difficult for human eyes to observe the same object for a long time. Machine vision can perform measurement, analysis and recognition tasks for a long time. However, manual detection is prone to miss detection and false detection. One visual inspection equipment can undertake the daily inspection tasks of multiple employees, and it is not easy to be interrupted, sick and need no rest. It can work continuously with high toughness and has low requirements on the natural environment of application, which not only saves the product cost, but also greatly improves the productivity.
Fourthly, it has a wider spectral response range.
The spectral response of CCD is 400- 1 100nm, which is much longer than the near-infrared effective band (350-700nm) of conventional photography. Using infrared measurement invisible to human eyes, the visual range of human beings is expanded.
Fifth, the detection range is wide, which can detect appearance defects and size measurement.
Machine vision technology can accurately measure the profile, specifications, appearance defects, length-width ratio and other performance parameters of the product to be detected at one time according to the multi-station inspection method; Manual detection has different reactions to different detection contents. Just according to the coordination of multiple sites, different personnel have different detection standards, which is prone to false detection.
Sixth, improve product quality and error rate.
Based on system control, CCD vision inspection equipment distinguishes good products from bad products through automatic inspection technology, and then automatically places them in different parts. Compared with manual inspection, ccd vision inspection equipment reduces the error rate, greatly improves the product quality, and improves the company's trust and comprehensive strength.
7. CCD visual inspection has good linearity.
The imaging intensity is directly proportional to the incident luminous flux and has a good linear relationship.
