Abstract:

In this work, according to the characteristics of analytes, using XXY table and angular displacement tables to construct an automatic verticality measurement and correction system for three axes. For the purpose of measuring and correcting the spatial verticality of analytes in three axial directions, in this study, using a XXY table and angular displacement tables to set up a simulate carrier, these tables are driven by a four axes motion controller to adjust their posture, and then utilizing five laser displacement meters and self-developed signal processing program to carry out the measurement work. The system sets five laser displacement sensors in the surroundings of analytes respectively, and using the measured data by laser displacement sensors to calculate the yaw, pitch and roll angles of the analytes. Finally, by the four axes motion controller to adjust the motion of these tables, let laser light perpendicular to the surface of analytes as far as possible to achieve the goal of this system. After the experimental verification, the average error is not more than 0.0417 degrees.
