[0002] X-ray imaging inspection systems are specialized inspection equipment based on digital imaging technology. They primarily utilize X-rays to penetrate the object being inspected and generate images, enabling non-destructive testing of internal defects in materials. These systems feature high precision, high resolution, and automated analysis capabilities. The resolution of an X-ray imaging system is a comprehensive and crucial indicator, its performance depending on several core factors, including the characteristics of the X-ray source, the source resolution (i.e., focal size), the detector resolution, and the relative spatial relationships between the source, detector, and object under test. In the current field of inspection technology, testing methods for X-ray source resolution (focal size) and detector resolution have become relatively mature and standardized.

The radiation source drive module 5 is located at one end of the reference platform 1. The radiation source 2 is fixedly mounted at the output end of the radiation source drive module 5, which drives the radiation source 2 to move linearly. The detector 3 is fixedly mounted at the output end of the detector drive module 6, which drives the detector 3 to move linearly in the horizontal and / or vertical directions. The loading platform 4 is fixedly mounted at the output end of the loading platform drive module 7, and is located between the radiation source 2 and the detector 3. The loading platform drive module 7 drives the loading platform 4 to move. The X-ray source drive module 5, the platform drive module 7, the detector drive module 6, and other components are all electrically connected to an external motion control system. The motion control system controls the movement speed, movement distance, or rotation angle of these motion drive modules 611 and provides timely feedback on the position parameters of each component. This helps to control the relative positions of components such as the X-ray source 2, the platform 4, and the detector 3, preventing them from colliding with each other. At the same time, by precisely controlling the movement of components such as the X-ray source 2, the platform 4, and the detector 3, CT scanning is achieved.
[0015] like Figure 2As shown, the X-ray source driving module 5 is fixedly mounted at one end of the reference platform 1 along the width direction of the reference platform 1. The X-ray source driving module 5 includes a first lifting linear module 51, a base plate 52, and a first guide post 53.

The X-ray source 2 is fixedly mounted at the output end of the first lifting linear module 51. The output end of the first lifting linear module 51 is inserted into the first guide post 53 and moves along the first guide post 53 under the drive of the servo motor, thereby driving the X-ray source 2 to perform linear motion and realizing the vertical position adjustment of the X-ray source 2.

The detector 3 is fixedly mounted on the output end of the second lifting linear module 621, and the output end of the second lifting linear module 621 is inserted into the second guide post 623 and moves along the second guide post 623 under the drive of the servo motor, thereby driving the detector 3 to move linearly in the vertical direction. Through the coordinated action of the horizontal motion module 61 and the vertical motion module 62, the detector 3 can move flexibly in both the horizontal and vertical directions to meet the needs of different test positions.
[0016] The platform drive module 7 includes a linear motion module 71 and a third guide post 72; wherein, the third guide post 72 is parallel to the linear motion module 71 and is disposed on the output end of the horizontal motion module 61 along the length direction of the output end of the horizontal motion module 61; the platform 4 is fixedly disposed on the output end of the linear motion module 71, and the linear motion module 71 can drive the platform 4 to move linearly along the width direction of the reference platform 1.
