Design of microcontroller System for Surface Scanning of Micro-Steel Ball

摘要

Based on the detection requirements of surface and sub-surface of micro steel ball, control system of defect scanning is studied, aiming at the problem of unfolded surface of steel ball, STC89S52 microcontroller is considered as the control core, then the feasible method of speed and direction control of step motor that driven by detection device, and hardware interface circuit and design of software solutions of the system are put forward, principles of unfolded surface of steel ball and control system of defect scanning and signal about defect scanning are analyzed, then the result are verified valid through the experiment. The results indicate that unfolded mechanics could be driven and flawed steel balls could be detected by the system of surface scanning of micro steel ball, which meet the design requirements.
