It drives the first rotating shaft 17 to rotate through the first driving motor 16, thereby driving the movable mounting seat 21 mounted thereon to precisely move in the x-axis direction. At the same time, the z-axis motion module 8 also starts to work. It drives the second rotating shaft 19 to rotate through the second driving motor 18, causing the mounting plate 20 to precisely move in the z-axis direction. This combination of x-axis and z-axis movements enables the industrial scanning camera 22 and the 2D vision camera 23 mounted on the movable mounting seat 21 to cover all areas of the die-casting, achieving comprehensive detection. At the same time, the 3D line scanning camera 13 and the auxiliary scanning camera 14 also start to work. The 3D line scanning camera 13 captures the three-dimensional data of the die-casting through its high-resolution scanning head, while the auxiliary scanning camera 14 provides additional visual information such as color and texture. These data are transmitted to the device control system for subsequent processing and analysis. In the result output stage, the device control system will analyze and statistically process the detected defect data and generate corresponding detection reports. These reports can be directly displayed to the operator through the display screen or exported through the connected host computer software, facilitating subsequent quality management and production control.
