With the development of artificial intelligence, vision technology is becoming more and more mature, especially within the industrial field with prominent applications, such as vision robotics, vision measurement, etc. Vision robotics can distinguish, select, discriminate, pick up, avoid and other actions on the distinguished objects; while vision measurement technology judges the size and accuracy of the objects and quickly makes the corresponding measurement display. This technology is especially applicable in microelectronics, optics, and small precision parts industries, and can assist quality inspectors in quickly completing quality full inspection of batch accuracy tolerances. It can completely replace the CMM, which not only improves the efficiency of batch inspection, but also saves the cost of quality control.
Description of vision measurement machine: HPT intelligent vision measuring instrument adopts industrial grade 20 million pixels and X0.26 double telecentric lens with φ50mm parallel light source + φ80mm annular light source. Equipped with precision lifting slide (5um), servo motor and motion control card. The carrier stage adopts full-plane sapphire glass, which can reach 0.005mm level inspection accuracy.
Advantage comparison.
(1) The traditional manual measurement method or quadratic measurement method, its general accuracy is not high, generally at about 20 microns, can not meet the measurement of precision products, quality can not be fully controlled. And the HPT vision measuring instrument has a detection accuracy of 5 microns, which can meet the measurement needs of high precision products.
(2) The efficiency of CMM is 5 minutes/pc on average, which can't meet the comprehensive inspection of all products. While the speed of HPT vision measurement is about 2 to 5 seconds/pc, and its high efficiency can meet the batch full inspection. It can also be equipped with joint or truss manipulator, which can fully realize unmanned automatic inspection.
