2D 비전시스템의 정밀 교정을 위한 고정밀 3축 직교로봇의 기계장치 설계

초록

In this paper, we designed and fabricated a mechanical device for a precision 3-axis Cartesian robot capable of calibrating a high-precision 2D vision system for accurate object dimension measurements. The 3-axis Cartesian robot was conceptually designed to allow system calibration by moving the vision system attached to the end-effector along the x, y, and z axes. Structural analysis was performed using the SolidWorks software program to minimize displacement along the x, y, and z axes. The 3-axis Cartesian robot was fabricated based on the design results. Characteristic tests of the fabricated robot revealed maximum travel distances of 240, 240, and 300 mm along the x, y, and z axes, respectively, and minimum travel distances (resolution) of 0.185, 0.185, and 0.007 µm, respectively. Therefore, the 3-axis Cartesian robot fabricated in this study is expected to be capable of precisely calibrating 2D vision systems.
