The advanced aspects of aoi automated optical inpsection
"Industry 4.0" "Internet +" artificial intelligence... These terms frequently appear in people's information field of view, whether it is active response or passive acceptance, an unstoppable historical trend is coming on the back, and behind all these rapid changes, In the industrial field, they all point to a common goal - smart manufacturing. As the intelligent manufacturing industry with high integration of automation and information technology, the biggest difference from the previous industrial production methods is the high degree of technology intensiveness, and the integration of a large number of intellectual resources and research and development environment has become the primary threshold for entering the industry.
The AOI automated optical inspect equipment uses a transmissive digital micro-module for small-area imaging, and uses ultra-high-precision motion platform to drag the sample, step-by-step motion, and achieve splicing of the image to achieve high precision and full range of the sample. measuring. The back-end application uses high-performance intelligent digital image processing related technology to analyze images and automatically identify various defects of parts. Provide support for the post-processing of parts production and production process improvement.
Because the motion precision of the AOI equipment is very high, and it is interfered with by the adjacent station handling and cutting equipment in the production line, an optical isolation platform is used to effectively isolate the ground disturbance. The selected three-dimensional air spring type vibration-removing table is a honeycomb table made of clean and high rigidity. The honeycomb table is made of honeycomb steel on the inner honeycomb material, and the upper and lower surfaces of the honeycomb table are processed before forming. Therefore, there is no cutting oil and chip residue inside, which is very clean; the vibration-removing part adopts an all-round corresponding air spring to achieve a high level of vibration-removing performance.
In the calculation method of automatic intelligent recognition of part defects, after the precise positioning of the parts is completed, the adaptive binarization algorithm is used to distinguish the foreground and the background and the Canny operator for edge detection, and the edge graphics are coordinately located according to the Hough variation.
AOI automated optical inpsection is a device that detects common defects encountered in production based on optical principle. It is a relatively standardized branch of visual inspection and has been widely used in various industries.
