Zusammenfassung:The invention discloses a calibration method and system of a photoelectric encoder, and the method comprises the steps: carrying out the initial positioning of a code disc and a photoelectric sensor; placing a corner reflecting prism on one side of the code channel scribed line on the code disc and a sensor pattern for alignment on the photoelectric sensor, and observing the code channel scribed line and the sensor pattern based on the reflected light of the corner reflecting prism; and adjusting the position when the relative position of the code channel scribed line and the sensor graph does not meet the preset requirement. The technical scheme provided by the invention aims to solve the technical problems of low efficiency and complex operation of the existing photoelectric encoder. 本发明公开一种光电编码器的校准方法和系统,其中,所述方法包括:对码盘和光电传感器进行初定位;在所述码盘上的码道刻线和所述光电传感器上用于对位的传感器图形朝向的一侧放置角反射棱镜,基于所述角反射棱镜的反射光观察所述码道刻线和所述传感器图形;在所述码道刻线和所述传感器图形的相对位置不符合预设要求时进行位置调节。本发明提供的技术方案旨在解决现有的光电编码器低效且操作复杂的技术问题。
