Visual inspection system of bogie

The embodiment of the invention provides a visual inspection system for a bogie. The visual inspection system comprises: a mounting frame; mechanical arms, which are mounted on the mounting frame, and can move along the mounting frame in at least one linear direction; and image acquisition devices, which are fixed to the open ends of the mechanical arms, and can adjust the angle and the posture along with the mechanical arms so as to reach a detection position of the bogie and acquire a fastener image at the detection position. According to the embodiment of the invention, the technical problem of low detection efficiency due to the fact that traditional anti-loose mark detection basically depends on manual inspection after the bogie is assembled is solved. 本申请实施例提供了一种转向架的视觉检测系统，包括：安装框架；机械臂，安装于所述安装框架，所述机械臂至少在一个直线方向能够沿所述安装框架移动；图像采集装置，固定于所述机械臂的开放端，所述图像采集装置能够随着所述机械臂调整角度和姿态，以到达转向架的检测位置，采集检测位置处的紧固件图像。本申请实施例解决了传统的转向架装配后防松标记检测基本依靠人工检查，检测效率低的技术问题。
