It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only parts related to the present utility model rather than all structures are shown in the attached drawings.

Moreover, the first feature being "above", "above the top of", and "on the top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below the bottom of", and "under the bottom of" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature.

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for differentiation in description and have no special meaning.

[0030] Please refer to Figures 1 to 3 As shown, this preferred embodiment provides an on-line X-ray double-track and double-source detection device, which includes a conveying system and an imaging system, wherein:

[0031] The conveying system includes two chain conveying tracks 1 arranged side by side, and the chain conveying tracks 1 are used for conveying materials to be inspected;

[0032] The imaging system includes a ray source movement module 2 and an imager movement module 3. The ray source movement module 2 includes a first three-axis drive mechanism 21 and two ray sources 22. The two ray sources 22 are independently driven by the first three-axis drive mechanism 21 and can move arbitrarily above the chain conveying track 1; the imager movement 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 conveying track 1.

[0033] Thus, this on-line X-ray double-track and double-source detection device designs a double-track and double-source detection structure, that is, a total of two sets of ray sources 22 and flat panel detectors 32 are designed above and below the two chain conveying tracks 1. The double-chain conveying tracks 1 and the double ray sources 22 cooperate to detect simultaneously, effectively improving the detection efficiency and the production capacity of the whole line, and providing a new design idea for high-efficiency material detection equipment.

[0034] 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 a y-direction driver 211. The y-direction driver 211 is provided with double output ends, and an x-direction driver 212 is provided on the double output ends. The output ends of the two x-direction drivers 212 are respectively provided with z-direction drivers 213. The two ray sources 22 are respectively 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 respectively installed on the output ends of the two z-direction drivers 213 of the second three-axis drive mechanism 31.

[0035] Thus, the first three-axis drive mechanism 21 enables the two ray sources 22 to move arbitrarily in the space above the material to be inspected, and the second three-axis drive mechanism 31 enables the two flat panel detectors 32 to move arbitrarily in the space below the material to be inspected. Moreover, the two ray sources 22 and the two flat panel detectors 32 can operate independently of each other without interference. Therefore, single detection and collaborative detection can be achieved, and the detection efficiency is increased by more than twice.

[0036] Preferably, the driving direction of the x-axis driver 212 is the same as the conveying direction of the two chain conveying tracks 1, the driving direction of the y-axis driver 211 is perpendicular to the conveying direction of the two chain conveying tracks 1 in the horizontal plane, and the driving direction of the z-axis driver 213 is perpendicular to the conveying direction of the two chain conveying tracks 1 in the vertical plane.

[0037] Specifically, the y-axis driver 211 adopts two double-moving sub linear motor modules arranged side by side. The x-axis driver 212 is horizontally mounted on a set of moving parts of the two double-moving sub linear motor modules, forming a gantry double-drive structure, which has higher stability and accuracy.

[0038] Preferably, the x-axis driver 212 and the z-axis driver 213 respectively adopt linear modules, which are characterized by high flexibility and precise movement, and other linear drive mechanisms can also be applicable.

[0039] Particularly, each chain conveying track 1 includes two track frames arranged side by side. Conveying chains 13 are respectively arranged on the opposite sides of the two track frames. The conveying chains 13 on both sides form supports along the two sides of the material to be inspected. This conveying method can reduce the interference of the conveying system on the detection result as much as possible and meet the conveying requirements.

[0040] Furthermore, the conveying system further includes a width adjustment mechanism 4. One of the two track frames in each chain conveying track 1 is a fixed track frame 11, and the other is a movable track frame 12. The width adjustment mechanism 4 is used to drive the movable track frame 12 to approach or move away from the fixed track frame 11, so that the distance between the two conveying chains 13 in each chain conveying track 1 matches the width dimension of the material to be inspected, in order to adapt to materials to be inspected with more sizes.

[0041] Specifically, the width adjustment mechanism 4 includes two adjustment drivers 41 arranged side by side. The movable track frame 12 is horizontally mounted on the output ends of the two adjustment drivers 41, and the fixed 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 the linear movement of the movable track frame 12 towards the fixed track frame 11.

[0042] Specifically, the fixed track frames 11 of one chain conveying track 1 and the fixed track frames 11 of another chain conveying track 1 are distributed at both ends of two adjusting drivers 41, and the movable track frames 12 of the two chain conveying tracks 1 are driven by the adjusting drivers 41 to reciprocate towards the corresponding fixed track frames 11 respectively.

[0043] In addition, the on-line X-ray double-track and double-source detection device further includes a lead chamber. The conveying system and the imaging system are both arranged in the lead chamber. The lead chamber is provided with feeding and discharging openings corresponding to the two chain conveying tracks 1, and lead curtains are arranged on the feeding and discharging openings to achieve isolation and protection of X-rays.

[0044] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting 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 in the protection scope of the claims of the present invention.
