[0028] Please refer to Figure 1 and Figure 2 As shown, this preferred embodiment provides an on-line X-ray dual-system detection device, which includes a lead room and a conveying system and an imaging system arranged in the lead room, wherein:

[0029] The conveying system includes a chain conveying track 1, and the chain conveying track 1 is used for conveying the material to be inspected 5;

[0030] The imaging system includes a radiation source motion module 2 and an imager motion module 3. The radiation source motion module 2 includes a first three-axis drive mechanism 21 and two radiation sources 22. The two radiation sources 22 are independently driven by the first three-axis drive mechanism 21 and can move arbitrarily above the chain conveyor track 1. The imager motion module 3 includes a second three-axis drive mechanism 31 and two flat panel detectors 32. The two flat panel detectors 32 are independently driven by the second three-axis drive mechanism 31 and can move arbitrarily below the chain conveyor track 1.

[0031] Thus, the on-line X-ray dual-system detection device designs a detection structure with a single track and dual sources, that is, two sets of radiation sources 22 and flat panel detectors 32 are designed above and below a single chain conveyor track 1. The two sets of radiation sources 22 and flat panel detectors 32 cooperate in detection simultaneously, effectively improving the detection efficiency, increasing the production capacity of the whole line, and providing a new design idea for high-efficiency material detection equipment.

[0032] Particularly, the first three-axis drive mechanism 21 and the second three-axis drive mechanism 31 here have the same or similar structures. Taking the first three-axis drive mechanism 21 as an example, it includes an x-direction driver 211. The x-direction driver 211 is provided with dual output ends, and y-direction drivers 212 are respectively arranged on the dual output ends. The output ends of the two y-direction drivers 212 are respectively provided with z-direction drivers 213. The two radiation sources 22 are correspondingly installed on the output ends of the two z-direction drivers 213 of the first three-axis drive mechanism 21, and the two flat panel detectors 32 are correspondingly installed on the output ends of the two z-direction drivers 213 of the second three-axis drive mechanism 31.

[0033] Thus, the two radiation sources 22 can move arbitrarily in the space above the material to be inspected 5 through the first three-axis drive mechanism 21, and the two flat panel detectors 32 can move arbitrarily in the space below the material to be inspected 5 through the second three-axis drive mechanism 31. Moreover, the two radiation sources 22 and the two flat panel detectors 32 can operate independently of each other without interference. Therefore, single detection and cooperative detection can be realized, and the detection efficiency is increased by more than 1.5 times.

[0034] Preferably, the driving direction of the x-direction driver 211 is the same as the conveying direction of the chain conveyor track 1, the driving direction of the y-direction driver 212 is perpendicular to the conveying direction of the chain conveyor track 1 in the horizontal plane, and the driving direction of the z-direction driver 213 is perpendicular to the conveying direction of the chain conveyor track 1 in the vertical plane.

[0035] Specifically, the x-direction driver 211 adopts two double-moving-sub straight-line motor modules arranged side by side. The y-direction driver 212 is horizontally mounted on a set of moving sub of the two double-moving-sub straight-line motor modules, forming a gantry dual-drive structure with higher stability and accuracy.

[0036] Preferably, the y-direction driver 212 and the z-direction driver 213 respectively adopt linear modules, which are characterized by high flexibility and precise movement, and other linear drive mechanisms can also be applicable.

[0037] Particularly, the chain conveyor track 1 includes two track frames 11 arranged side by side. Conveyor chains 12 are respectively arranged on the opposite sides of the two track frames 11. The conveyor chains 12 on both sides form supports along the two sides of the material to be inspected 5. This conveying method can minimize the interference of the conveying system on the inspection results and meet the conveying requirements.

[0038] Furthermore, the conveying system further includes a width adjustment mechanism 4. The width adjustment mechanism 4 is used to drive one track frame 11 to approach or move away from the other track frame 11, so that the distance between the two conveyor chains 12 matches the width dimension of the material to be inspected 5, in order to adapt to materials to be inspected 5 of more sizes.

[0039] Specifically, the width adjustment mechanism 4 includes two adjustment drivers 41 arranged side by side. One track frame 11 is horizontally mounted on the output ends of the two adjustment drivers 41, and the other track frame 11 is located at the ends of the two adjustment drivers 41. Here, the adjustment driver 41 can also adopt a linear module to realize the function of linearly moving one track frame 11 towards the other track frame 11.

[0040] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
