Abstract: A device for automatically detecting a through-hole rate of a honeycomb sandwich composite-based acoustic liner, including a customized tooling, a data acquisition system, a motion mechanism and a data processing system. The data acquisition system is configured to acquire a surface three-dimensional (3D) point cloud data of an acoustic liner using a two-dimensional (2D) laser profile sensor in a manner of parallel movement shooting, and connected with a graphics workstation. The motion mechanism includes an industrial robot, and the 2D laser profile sensor is fixed at an end of the industrial robot. The motion mechanism is configured to support the data acquisition system to perform translational scanning. The data processing system includes the graphics workstation, and plays a role of path planning and data storage. A method for automatically detecting a through-hole rate of a honeycomb sandwich composite-based acoustic liner is also provided.
