Visual inspection development has been more than 20 years of history, his function and application range are also with the development of industrial automation to improve and promote gradually, especially is currently uvled visual check the light source, digital image sensor, CMOS and CCD camera, embedded technology, the rapid development of image processing and pattern recognition technology, greatly promote the development of machine vision.

Uvled visual check the advantage of the light source:

1, non-contact measurement, the observer and the observer will not cause any damage, so as to improve the reliability of the system;

2, has a wide range of spectral response, such as user see invisible infrared measurement, expanded the scope of human eye vision;

3, work stably for a long time, the human long hard time to look at the same object, while machine vision can be a long time for measurement, analysis and recognition task.

Application field of uvled visual inspection of the light source:

1, the printing industry, printing quality detection, printing detection, color character recognition, bar code identification, qr code detection, etc.;

2, electronic industry, semiconductor element characteristics of surface defect detection, character printing the imperfect detection, component damage detection, packaging integrity detection chip pin, terminal; Pin size detection, braiding machine component polarity identification, keyboard characters detection, etc.;

3, automotive electronics: panel printing quality detection, character, color recognition, AOI inspection system, etc.;

4, the health care industry: bottle defect monitoring, pill packaging void detection, capsule packaging quality detection, etc.;

5, the food industry: appearance encapsulation testing, appearance and internal quality of eggs, fruit color judgment, food packaging visual positioning, etc.
