[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Through the design of the present invention, the reliance on the skills of the X-ray operator can be reduced, the time spent on placing the workpiece can be reduced, and the repeatability and consistency of the X-ray detection process can be ensured. The more important advantage is that by reducing the position change of the five-axis motion system composed of the X-ray machine, the stage and the imaging plate during the multi-workpiece detection process, the time required for X-ray transillumination of multiple workpieces is significantly reduced, and the detection efficiency is improved; at the same time, it can ensure that the imaging structure of the left part of the workpiece and the right part of the workpiece on the tooling remains consistent at the same detection position, avoiding the need for re-adaptation caused by the change of the imaging image, which not only facilitates the inspector's assessment of defects, but also facilitates the accurate positioning of defects on the workpiece, thereby further improving the detection efficiency; in addition, it can accommodate multiple workpieces at the same time and is also suitable for a variety of drawing numbers.
