| Abstract: | In terms of the technical requirements on quality detection of the surface and sub-surface of a micro steel ball,this paper analyzed the working principle of the device unfolding the surface of micro steel ball and scanning defect,as well as the principle for processing the defect detection signal.A control system to unfold the surface of micro steel ball and detect defection was designed,involving the step motor speed and direction control method based on the STC89S52 microcontroller,the hardware interface circuit and control programme design.Then the result was verified through the experiment.The experimental results indicated that the unfolded mechanics could be driven and the flawed steel ball could be detected by the system of surface scanning and defect detecting,and thereby the design requirements could be met. |
