Abstract

The fiber positioning robot is an important part of LAMSOT's acquisition of celestial spectra, and the fiber positioning robot is routinely maintained every summer to ensure that its positioning accuracy meets the observation requirements. At present, in the process of maintaining the fiber positioning robot, the cause of the fault is analyzed by manually disassembling the fiber positioning robot, which takes a long time and is inefficient. In order to quickly locate the cause of the fault of the fiber positioning robot, this paper proposes to obtain the repeated positioning accuracy and actual rotation angle data of the fiber positioning robot through the fiber positioning robot motion accuracy experiment. Taking the experimental data as the robot performance diagnosis index, the fault cause of the fiber positioning robot is analyzed, and the performance diagnosis index and the fault cause are corresponded, and the fault diagnosis method of the fiber positioning robot is obtained. This method has high accuracy in identifying the cause of faults, effectively improves the maintenance efficiency of fiber positioning robots, greatly reduces labor and time costs, and has reference value for the maintenance and design of fiber positioning robots using similar double rotary gear transmission.
