The applied research on a new type of photoelectricity automatic positioning system

Abstract

With the high-speed development of the social economy, the requirements of the positioning precision and response speed of product on the production line become higher and higher. A new type of photoelectricity automatic positioning system is developed, which consists of vision sensor charge coupled device (CCD), digital image processing and stepper motor controller. They form a closed loop control system, which captures the images by the optical system, achieves photoelectric signal conversion by data image processing and controls the movements of worktable along the X and Y directions by stepper motors. As a result, it achieves fast automatic positioning and compensates the systematic errors effectively, which improves the positioning precision dramatically. In the photoelectric on-line of detecting throttle position sensor resistor, as an example of design, the photoelectric positioning system proves the correctness of the novel photoelectricity automatic positioning system. The positioning time of the system is 0.7s and the positioning precision of the system is 0.35mm, which get ideal results. The experiment of the application has proved that the new type of photoelectric automatic positioning system can be applied in the correlative production line, which has vital significance to improve the accuracy of product processing, reduce the processing time, and increase economic efficiency.
