Design of bit quality inspection system based on image
Description
In the drilling operation, the quality of drill will directly affect and determine the drilling quality, thus affecting the product quality and production cost. Therefore, it is necessary to detection of new drill and after grinding drill surface shape, so as to ensure the quality of processed products. The task of this project is to design the automatic detection system to determine the shape of the cutting edge of the middle and small size drills. The research status of automatic optical inspection method and technology is analyzed and studied, the overall scheme of the system is determined, the analysis and design of detection system and mechanical structure system are analyzed and the structure diagram is drawn. The main content of this thesis is based on visual technology in small drill bit blade surface of the automatic optical detection methods of analysis and design, the overall design of the system, mechanical structure design, drive control design, general post data processing method. The diameter of the drill is in the range of 1mm~5mm, and the accuracy is 10um. In this paper, the most important part of the design of mechanical analysis, and the optical detection system is briefly described.
