[0002] X-ray industrial CT non-destructive imaging is an important means of quality imaging in modern industrial production and is widely used in aerospace, aviation, railway systems, and the manufacturing of heavy machinery.

[0003] In industrial settings, assembly and debugging work is primarily performed while standing. To accommodate this posture, most industrial X-ray CT imaging systems, both domestically and internationally, employ a vertical design. To ensure equipment stability, the height of the equipment is limited to prevent a high center of gravity from affecting stability. This limitation also restricts the size of the objects that can be mounted in a vertical CT imaging system.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a desktop horizontal CT imaging system to increase the maximum imaging size of the CT imaging system.

[0006] The technical solution of this utility model is as follows: The desktop horizontal CT imaging system includes a platform, an imager, an imaging fixation plate, a horizontally mounted X-axis linear module for carrying an object, a radiation source slidably connected to the X-axis linear module, a stage, and a sliding support plate. The imager is movably mounted on the sliding support plate. The imaging fixation plate connects both the platform and the imager. An adjusting bolt perpendicular to the sliding direction of the X-axis linear module is provided between the imaging fixation plate and the imager. The adjusting bolt connects both the imaging fixation plate and the imager. The stage is positioned between the imager and the radiation source. The stage carries the imaging object. The imager and the imaging object are positioned along the radiation path of the radiation source.

[0007] A further technical solution is that the platform is also provided with an imaging fixation bracket and a ray fixation bracket; the imaging fixation bracket is movably mounted on the sliding support plate, and the imager is mounted on the imaging fixation bracket; the ray fixation bracket is slidably connected to the X-axis linear module of the object carrier, and the ray source is mounted on the ray fixation bracket.

[0008] A further technical solution is that a radiation fixation plate is also provided on the platform; the radiation fixation plate connects both the platform and the radiation fixation bracket.

[0009] A further technical solution is that, along the sliding direction of the X-axis linear module of the object carrier, a positioning hole is opened on the platform; positioning components are respectively provided on the imaging fixing plate and the ray fixing plate to connect the positioning hole.

[0010] A further technical solution is that a load support base is provided on the platform; a load Y-axis linear module is horizontally arranged on the load support base; the load platform is slidably connected to the load Y-axis linear module; and the load Y-axis linear module adopts a screw drive mechanism.

[0011] A further technical solution is that a load support frame is provided on the load support base; the load support frame is slidably connected to the load Y-axis linear module, and a load Z-axis linear module is vertically provided on the load support frame; the load platform is slidably connected to the load Z-axis linear module; the load Z-axis linear module adopts a screw drive mechanism.

[0012] A further technical solution is that a turntable is provided on the load support frame; the turntable is slidably connected to the load Z-axis linear module; and the load platform is disposed on the turntable.

[0014] A further technical solution is that the lead screw transmission mechanism includes a lead screw, a power source connected to the lead screw, and a sliding nut.

[0015] The beneficial technical effects of this utility model are as follows: (1) In the tabletop horizontal CT imaging system of this utility model, the stage, X-ray source, and imager are slidably connected to the platform by a linear X-axis module. The linear X-axis module allows for easy adjustment of the distance between the stage, X-ray source, and imager, improving the imaging flexibility of the tabletop horizontal CT imaging system. Furthermore, the X-ray source and imager are positioned laterally for imaging. When mounting the imaging object, the object can be positioned laterally on the stage, facilitating imaging of objects with a large aspect ratio. Additionally, with the imaging object positioned laterally and the support point located in the middle of the object, the length of the lever arm extending from both ends of the object is reduced, and the fixing point is close to the center of gravity of the workpiece, enhancing the stability of the imaging object. The large contact area between the laterally positioned platform and the placement plane disperses the force, enhancing the overall stability of the tabletop horizontal CT imaging system.

[0016] (2) Furthermore, the imaging fixation bracket is mounted on the sliding support plate and connected to the platform via the imaging fixation plate. Adjusting the adjusting bolts can adjust the positional relationship between the imaging fixation bracket and the imaging fixation plate, thereby fine-tuning the position of the imaging fixation bracket on the platform, enhancing the flexibility of the desktop bedroom CT imaging system, and facilitating the imaging of a complete view of the object being detected.

[0017] (3) Furthermore, a Y-axis linear module, a Z-axis linear module and a turntable are also provided between the platform and the stage. Through the Y-axis linear module, the Z-axis linear module and the turntable, the front and rear position, height and angle of the stage relative to the platform can be flexibly adjusted, further enhancing the flexibility of the desktop bedroom CT imaging system and facilitating the imaging of more angle views.

[0024] Figure 1 A three-dimensional structural schematic diagram of a desktop horizontal CT imaging system according to an embodiment of the present disclosure is shown. Figure 2 A three-dimensional structural diagram of a desktop horizontal CT imaging system according to an embodiment of the present disclosure is shown, with the protective cover removed. Please refer to... Figure 1 and Figure 2 The desktop horizontal CT imaging system includes a platform 1, a horizontally mounted X-axis linear module 13, a stage 2 slidably connected to the X-axis linear module 13, an imaging fixation bracket 11, and a radiation fixation bracket 12. The stage 2 is positioned between the imaging fixation bracket 11 and the radiation fixation bracket 12. The stage 2 carries the imaging object. A radiation source 5 is positioned on the side of the radiation fixation bracket 12 closest to the imaging fixation bracket 11. An imager 4 is positioned on the side of the imaging fixation bracket 11 closest to the radiation fixation bracket 12. The imager 4 and the imaging object are positioned in the radiation path of the radiation source 5. The X-axis linear module 13 allows for easy adjustment of the distance between the stage 2, the radiation source 5, and the imager 4, improving the imaging flexibility of the desktop horizontal CT imaging system. Furthermore, the radiation source 5 and the imager 4 are positioned horizontally for imaging. When mounting the imaging object, the object can be positioned horizontally on the stage 2, facilitating imaging of objects with a large aspect ratio. Furthermore, the imaging object is positioned laterally, with the support point located in the middle of the imaging object. This reduces the length of the lever arms extending from both ends of the imaging object, and the fixed point is close to the center of gravity of the workpiece, enhancing the stability of the imaging object setup. The laterally positioned platform 1 has a large contact area with the placement plane, distributing the force and enhancing the overall stability of the desktop bedroom CT imaging system.

[0025] In some embodiments, the imager 4 can be a commercially available Iray NDT / Mercu series high frame rate flat panel detector, and the X-ray source 5 can be a commercially available Iray Libra series microfocus X-ray source 5. Specifically, during imaging, the X-ray source 5 generates X-rays, which are captured by the imager 4. Imaging is achieved by utilizing the different absorption / scattering degrees of X-rays at different densities and thicknesses when the X-ray beam penetrates the object being inspected. A protective cover 3 can also be provided, with the platform 1 and stage 2 housed inside. The protective cover 3 is made of lead plate, forming a shielded lead room to shield against ionizing radiation generated during imaging, prevent radiation leakage, and protect operators and the external environment.

[0026] Figure 3 A partial enlarged view at point A is shown of a desktop horizontal CT imaging system according to an embodiment of this disclosure. Please refer to... Figure 2 and Figure 3 Platform 1 is also equipped with an imaging fixation plate 112 and a radiation fixation plate 121. The imaging fixation plate 112 connects both platform 1 and the imaging fixation bracket 11, and the radiation fixation plate 121 connects both platform 1 and the radiation fixation bracket 12. The imaging fixation bracket 11 and the radiation fixation bracket 12 are fixed on platform 1 by the imaging fixation plate 112 and the radiation fixation plate 121, preventing the imaging fixation bracket 11 and the radiation fixation bracket 12 from sliding along the slide rail 64 and enhancing the stability of the tabletop horizontal CT imaging system.

[0027] Preferably, a sliding support plate 111 is also provided on platform 1. The sliding support plate 111 is slidably connected to the X-axis linear module 13 of the object carrier. The imaging fixation bracket 11 is provided on the sliding support plate 111. An adjusting bolt 113 is provided on the imaging fixation bracket 11, and the adjusting bolt 113 is also connected to the imaging fixation plate 112. By adjusting the adjusting bolt 113, the positional relationship between the imaging fixation bracket and the imaging fixation plate 112 can be adjusted, thereby fine-tuning the position of the imaging fixation bracket on platform 1, enhancing the flexibility of the desktop bedroom CT imaging system, and facilitating the imaging device 4 to image a complete view of the object being detected. Specifically, the adjusting bolt 113 is threadedly connected to the imaging fixation bracket. A nut (not shown in the figure) can be provided on the adjusting bolt 113, and the imaging fixation plate 112 is located between the head of the adjusting bolt 113 and the nut. By rotating the nut around the adjusting bolt 113, the nut cooperates with the adjusting bolt 113 to clamp the imaging fixation plate 112, fixing the position between the imaging fixation plate 112 and the imaging fixation bracket. When adjusting the position between the imaging fixing plate 112 and the imaging fixing frame, first rotate the nut to loosen the imaging fixing plate 112 and the adjusting bolt 113, then rotate the adjusting bolt 113 around the imaging fixing frame to adjust the distance between the imaging fixing plate 112 and the imaging fixing frame by changing the distance between the head of the adjusting bolt 113 and the imaging fixing frame, and then rotate the nut to tighten the adjusting bolt 113 and the imaging fixing plate 112.

[0028] More preferably, positioning holes 14 are provided on the platform 1 along the sliding direction of the X-axis linear module 13. Positioning members 114 are respectively provided on the imaging fixing plate 112 and the X-ray fixing plate 121 to connect to the positioning holes 14. By fixing the positioning members 114 in different positioning holes 14, the positions of the imaging fixing plate 112 and the X-ray fixing plate 121 fixed on the platform 1 can be quickly adjusted. In some embodiments, the positioning member 114 can be a screw, and the positioning hole 14 can be a screw hole.

[0029] Please refer to Figure 2 A support base 21 is mounted on platform 1. A Y-axis linear module 211 is horizontally mounted on the support base 21. The stage 2 is slidably connected to the Y-axis linear module 211. The Y-axis linear module 211 can be driven by a screw drive mechanism 6. The positional relationship between the stage 2 and platform 1 can be quickly adjusted along the sliding direction of the Y-axis linear module 211, facilitating the adjustment of the imaging object to a suitable imaging position and improving the flexibility of the desktop bedroom CT imaging system.

[0030] Preferably, a carrier support frame 22 is provided on the carrier support base 21. The carrier support frame 22 is slidably connected to the carrier Y-axis linear module 211, and a carrier Z-axis linear module 221 is vertically provided on the carrier support frame 22. The carrier stage 2 is slidably connected to the carrier Z-axis linear module 221. The carrier Z-axis linear module 221 can adopt a lead screw drive mechanism 6. Along the sliding direction of the carrier Z-axis linear module 221, the positional relationship between the carrier stage 2 and the platform 1 can be quickly adjusted, which facilitates the adjustment of the imaging object to a suitable imaging position and further improves the flexibility of the desktop bedroom CT imaging system.

[0031] More preferably, a turntable 23 is provided on the load support frame 22. The turntable 23 is slidably connected to the load Z-axis linear module 221. The load stage 2 is disposed on the turntable 23. The imaging object can be rotated along the rotation axis of the turntable 23, which facilitates the imager 4 to image views from more angles. In some embodiments, the turntable 23 is connected to a torque motor (not shown in the figure), and the torque motor drives the turntable 23 to rotate, thereby driving the imaging object to rotate.

[0032] Please refer to Figure 2 The X-axis linear module 13 includes a lead screw drive mechanism 6 and a slide rail 64. The stage 2 is connected to both the lead screw drive mechanism 6 and the slide rail 64. The slide rail 64 guides the stage 2, enhancing its stability during movement and thus reducing imaging errors. The imaging fixing bracket 11 and the X-ray fixing bracket 12 are respectively connected to the slide rail 64. Specifically, the stage support 21, the imaging fixing bracket 11, and the X-ray fixing bracket 12 are each provided with a groove (not shown in the figure) for the slide rail 64 to engage. A rolling element (not shown in the figure) can be provided between the slide rail 64 and the groove to reduce friction between them.

[0033] Preferably, the screw drive mechanism 6 includes a drive screw 61, a power source 62 connecting the drive screw 61, and a sliding nut 63. Specifically, the power source 62 can be a motor. A helical raceway is machined on the surface of the drive screw, and a corresponding internal thread raceway is provided inside the sliding nut 63 to engage with the helical raceway. The internal thread raceway and the helical raceway cooperate to convert the rotational motion of the drive screw 61 into the linear motion of the sliding nut 63. Ball bearings can also be provided between the helical raceway and the internal thread raceway to reduce friction. Taking the sliding connection between the platform 1 and the load support 21 as an example, the drive screw 61 is rotatably mounted on the platform 1, and the sliding nut 63 is connected to the load support 21. The power source 62 drives the drive screw to rotate, drives the sliding nut 63 to move along the drive screw, and thus drives the load support 21 to slide along the platform 1.

[0034] The specific workflow of this utility model is as follows: The operator places the object to be imaged on stage 2. The relative positions of the imaging fixture 11, the X-ray fixture 12, and the stage 2 are slid along the X-axis linear module 13. During adjustment, the nut on the adjusting bolt 113 can be rotated away from the imaging fixture 112, and then the adjusting bolt 113 can be rotated again to adjust the distance between the head of the adjusting bolt 113 and the imaging fixture 11, thereby fine-tuning the position of the imaging fixture 11 along the direction perpendicular to the X-axis linear module 13. Simultaneously, the position of stage 2 in the horizontal and vertical directions can be further adjusted using the Y-axis linear module 211 and the Z-axis linear module 221. Then, the imager 4 and the X-ray source 5 can be activated for imaging. During imaging, the object can be rotated via the turntable 23 to image from more angles.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
