Appearance selection machine selects the CCD camera to transform the target to be inspected into an image signal, based on the pixel distribution and brightness, color and other information, into digital signals, digital image processing system for these signals to carry out all kinds of operations to extract the characteristics of the target, such as the area, the number of locations, length, and then based on the pre-set permissible degree and other standards output results, including the height of the multiple segments, the width of the multi-degree, detecting Plug hole screening machine, broken needles, plug holes, tooth bottom diameter, tooth outer diameter, tooth spacing, oblique teeth, rubbing teeth abnormal, screw length, head plating, chamfering, plug holes, eccentricity, teeth and so on, thus completing the role of automated detection and identification.

Appearance selection machine selection of CCD visual inspection equipment imaging technology, to complete the production of a variety of products interchangeable manufacturing, the use of high-definition CCD industrial camera, light source and full-featured data processing software, to meet the quality of production quality monitoring regulations, according to the customer's product specifications and characteristics of the inspection provisions of the independent settings, based on the data of the test products, the product selection, divided into good, defective and re-inspection of the product, the product. The equipment system can bring the quality inspection report of the tested products, the equipment is very easy to operate for production change, and the utilization rate of production change is high.
