[0034] Please refer to Figure 1 and Figure 2 This embodiment discloses an industrial CT imaging device, including a base 100, a first linear module 200, a second linear module 300, a third linear module 400, and a first X-ray source 610. The first linear module 200 is mounted on the base 100, and the length of the first linear module 200 is distributed along a first direction, for example... Figure 1 In the left-right direction shown, the first linear module 200 is provided with a first slide 210 and a second slide 220 located on the same slide rail. The first slide 210 is connected to a first drive member 240, and the second slide 220 is connected to a second drive member 250. For example, both the first slide 210 and the second slide 220 are mounted on the first slide rail 230. The first drive member 240 is used to drive the first slide 210 to move along the direction of the first slide rail 230, and the second drive member 250 is used to drive the second slide 220 to move along the direction of the first slide rail 230, thereby adjusting the distance between the first slide 210 and the second slide 220 in the first direction. Both the first drive member 240 and the second drive member 250 can adopt a motor + lead screw transmission structure, or a motor + belt transmission structure, thereby realizing independent control of the first slide 210 and the second slide 220. The second linear module 300 is mounted on the first slide 210 and is orthogonally connected to the first linear module 200 on the horizontal projection plane, that is, the length of the second linear module 300 is along the second direction (e.g., Figure 1The second linear module 300 and the first linear module 200 are distributed in the front-to-back direction (as shown in the diagram). In the top-view direction, they are perpendicular to each other, thus achieving position adjustment in the orthogonal direction of the horizontal plane. A turntable 310 is mounted on the second linear module 300, and a clamping assembly 320 is provided on the turntable 310. The turntable 310 is a hollow rotating platform, which is stable, reliable, has a fast response speed, and high positioning accuracy. The clamping assembly 320 can be adjusted according to the size of the object being measured, accommodating objects of different sizes and meeting application needs in different scenarios. The third linear module 400 is mounted on the second slide 220 and parallel to the second linear module 300, avoiding positional deviation in the first direction, thus ensuring the independent movement of the third linear module 400 and the second linear module 300. A lifting module 410 is mounted on the third linear module 400, and a bracket 420 is mounted on the lifting module 410. The bracket 420 is provided with multiple assembly areas, such as... Figure 1 As indicated by markings Z1 and Z2, one of the multiple assembly areas is equipped with a radiation detector 500. In application, different models or sizes of radiation detectors 500 can be replaced according to different scenario requirements (see reference). Figure 1 and Figure 3 By setting up multiple assembly areas, it can be compatible with the assembly requirements of different X-ray detectors 500. The lifting module 410 can work with the first linear module 200 and the third linear module 400 to realize the three-dimensional movement of the X-ray detector 500 in the horizontal bidirectional and vertical directions, thereby adapting to the centering adjustment requirements of different X-ray detectors 500. The first X-ray source 610 is connected to the base 100 and is distributed on the opposite sides of the clamping assembly 320 with the X-ray detector 500.

[0035] Thus, the bracket 420 is equipped with multiple assembly areas, which can be used to replace different models of X-ray detectors 500 to meet the needs of different application scenarios. The lifting module 410 can adjust the height of the X-ray detector 500, thereby making it compatible with different models of X-ray detectors 500. The clamping assembly 320 can be compatible with objects of various sizes. The first linear module 200, together with the second linear module 300 and the third linear module 400, realizes the position adjustment of the object in the plane. The structure is simple, the operation is automated, and the position adjustment accuracy is high.

[0036] The structural principle of industrial CT imaging equipment is that X-rays emitted by the first X-ray source 610 penetrate the object being measured, placed on the clamping assembly 320, and are then imaged by the X-ray detector 500. Therefore, the emission center of the first X-ray source 610 should be aligned with the center of the X-ray detector 500. To improve the compatibility of different X-ray detectors 500, multiple assembly areas on the bracket 420 are concentrically arranged. When it is necessary to replace different X-ray detectors 500, the X-ray detector 500 can be easily installed on the bracket 420, reducing the center offset of the X-ray detector 500 and facilitating debugging, maintenance, and use. Each of the multiple assembly areas is provided with assembly holes, through which the X-ray detector 500 is connected to the bracket 420 via fasteners. Multiple assembly areas accommodate multiple commonly used X-ray detectors 500, and corresponding assembly holes are set in the assembly areas. Through the cooperation of assembly holes and fasteners (such as bolts), the X-ray detectors 500 can be easily installed into the corresponding assembly areas, reducing assembly errors of the X-ray detectors 500. The position of the installed X-ray detectors 500 can be finely adjusted by the cooperation of the first linear module 200, the third linear module 400 and the lifting module 410, thereby ensuring compatibility with different X-ray detectors 500 and improving the convenience of replacement.

[0037] Please refer to Figure 2 and Figure 4 To ensure compatibility with various X-ray detectors 500, the bracket 420 is relatively large, necessitating consideration of its assembly strength. Therefore, a connecting frame 430 is installed on the lifting module 410. The connecting frame 430 has a horizontal support surface, and the bracket 420 connects to this surface. The connecting frame 430 supports the bracket 420, improving its assembly strength. Both the connecting frame 430 and the bracket 420 are equipped with reinforcing ribs. For example, the connecting frame 430 has a first reinforcing rib 421 to enhance its load-bearing capacity, while the bracket 420 has a second reinforcing rib 431 to improve its lifting mechanical strength, thus meeting the support requirements for X-ray detectors 500 of different weights.

[0038] To obtain a clear image during application, the object under test should be placed within the radiation irradiation range of the first radiation source 610 and within the imaging detection range of the radiation detector 500. After commissioning, the first radiation source 610 is typically in a relatively stationary state. The horizontal distance between the object under test and the radiation detector 500 relative to the centerline of the first radiation source 610 can be adjusted by the cooperation of the second linear module 300 and the third linear module 400. Using identical linear modules for the second and third linear modules 300 ensures consistent performance between them, thereby improving the synchronization of the position adjustment between the object under test and the radiation detector 500.

[0039] A redundant area is provided between the first slide 210 and the first radiation source 610 (e.g., ...). Figure 3 As shown in the center (marked Z3), the redundant area is suitable for installing a second X-ray source 620. The first X-ray source 610 is a high-pressure X-ray source, which can meet the imaging quality requirements of most scenarios. However, for some applications, such as detecting samples with weak attenuation, a low-pressure X-ray source can be installed in the redundant area as the second X-ray source 620 to improve imaging contrast and enhance application compatibility across different detection scenarios. Either the first X-ray source 610 or the second X-ray source 620 can be selected.

[0040] Please refer to Figure 4 and Figure 5In some application examples, the clamping assembly 320 includes a first clamping part 321 and a second clamping part 322 that are movably connected. The first clamping part 321 is fixedly mounted on the turntable 310, and the gap between the first clamping part 321 and the second clamping part 322 passes through the center of the turntable 310. In use, the object to be measured is placed in the clamping area between the first clamping part 321 and the second clamping part 322. Using the first clamping part 321 as a positioning reference, the object to be measured is confined to one side of the turntable 310. By adjusting the position of the second clamping part 322, the object to be measured can be clamped. Under no-load conditions, the gap between the first clamping part 321 and the second clamping part 322 passes through the center of the turntable 310, thus allowing the object to be clamped and positioned on one side of the turntable 310. Driven by the turntable 310, the object rotates around its center, enabling imaging of various positions of the object to be measured, thus meeting the imaging requirements of objects with a centrally symmetrical structure. Furthermore, the clamping edge of the first clamping part 321 is close to the center line of the turntable 310, resulting in a larger clamping area between the second clamping part 322 and the first clamping part 321. This fully utilizes the space on one side of the turntable 310 and facilitates the compatibility of objects of more sizes. In other application examples, the clamping assembly 320 includes a first clamping part 321 and a second clamping part 322 that are movably connected. Both the first clamping part 321 and the second clamping part 322 are mounted on the turntable 310 and located on the same side of the center of the turntable 310. The first clamping part 321 and the second clamping part 322 can move relative to each other, thereby clamping and fixing the object to be measured on one side of the turntable 310, so that it can rotate around the center of the turntable 310 under the drive of the turntable 310.

[0041] Both the first clamping part 321 and the second clamping part 322 are made of low-density X-ray transmission material. The low-density X-ray transmission material can be titanium alloy, which has high mechanical strength and absorbs less X-rays, thus reducing interference with imaging; or, the low-density X-ray transmission material can be carbon fiber composite material, which has sufficient mechanical strength and does not significantly absorb or refract X-rays, ensuring clear imaging.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
