Technical Field

[0001] The utility model relates to an alignment device for high-precision X-ray imaging, belonging to the technical field of X-ray imaging. Background Art

[0002] X-rays are electromagnetic waves with extremely high frequencies, extremely short wavelengths, and large energies. The frequencies and energies of X-rays are second only to gamma rays. X-rays have penetrability. However, there are differences in density and thickness among human tissues. When X-rays pass through different human tissues, the absorption degrees are different, and different images can be obtained after imaging processing.

[0003] In factories with high confidentiality requirements, X-rays are often used to detect the items carried by employees. Usually, employees will place the carried objects in one place. However, when the carried items are placed in a messy manner, it will cause the X-ray detection equipment to be unable to accurately align with the items to be detected, thus affecting the accuracy of the images obtained after detection.

[0004] Therefore, an alignment device for high-precision X-ray imaging is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides an alignment device for high-precision X-ray imaging to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

A conveyor belt 206 is movably connected to the surfaces of the five first servo motors 208. The first servo motor 208 is arranged on the left side of the front side of the detection rack 1. The output end of the first servo motor 208 is connected to a first lead screw 209. A first nut 210 is threadedly connected to the surface of the first lead screw 209.

The output end of the DC motor 201 is connected to a connecting rod 202. Driving bevel gears 203 are installed on the surfaces of the connecting rod 202. The surfaces of the five driving bevel gears 203 are all meshed with the surfaces of the five driven bevel gears 204. The frame 207 is installed on the left side of the detection rack 1. The frame 207 is installed on the front side of the frame 207. An L-shaped rod 211 is installed at the top of the first nut 210. A moving frame 212 is installed on the right side of the L-shaped rod 211. The second servo motor 213 is installed on the left side of the moving frame 212.

[0031] By providing the adjustment mechanism 2, through the output of the DC motor 201, the driven bevel gear 204 rotates, and the conveyor belt 206 moves, moving the items on its top to the inside of the detection rack 1. Subsequently, through the outputs of the first servo motor 208 and the second servo motor 213, the first nut 210 and the second nut 215 have the characteristic of moving, so that the X-ray probe 4 can move in the front-back, left-right directions, enabling the X-ray probe 4 to automatically align with different items, avoiding the situation where the X-ray probe 4 cannot accurately align with the items to be detected, thus affecting the normal forming work of the detection pattern, resulting in inconvenient use of the equipment and affecting the operation of the operator.

[0032] Embodiment 2

[0033] In one embodiment, a limiting groove 217 is formed at the top of the moving frame 212. The second screw block 215 penetrates through the inner cavity of the limiting groove 217 and extends to the top of the moving frame 212. A sliding groove 218 is formed at the bottom of the moving frame 212. The sliding block 216 is slidably connected to the inner cavity of the sliding groove 218. Moving grooves 219 are formed on the surfaces of the left and right sides of the detection frame 1. The left and right sides at the bottom of the moving frame 212 are slidably connected to the inner cavities of the two moving grooves 219. A limiting rod 220 is installed in the inner cavity of the frame 207. The inner surface of the first screw block 210 is slidably connected to the surface of the limiting rod 220.

[0034] By providing the limiting groove 217, the movement of the second screw block 215 can be limited to prevent the second screw block 215 from shifting during movement, thus affecting the alignment work of the X-ray probe 4. By providing the sliding groove 218, the movement of the sliding block 216 can be limited to prevent the direction of the sliding block 216 from changing during movement, thus affecting the alignment effect of the X-ray probe 4. By providing the moving grooves 219, the movement of the moving frame 212 can be limited to ensure the accuracy of the movement of the moving frame 212, improving the convenience of the movement alignment work of the X-ray probe 4. By providing the limiting rod 220, the movement of the first screw block 210 can be limited to prevent the first screw block 210 from rotating synchronously with the first lead screw 209, thereby affecting the adjustment and alignment work of the X-ray probe 4.

[0035] When the present utility model is in operation: through the output of the DC motor 201, the connecting rod 202 drives the driving bevel gear 203 to rotate. At this time, through the mutual cooperation of the driving bevel gear 203 and the driven bevel gear 204, the roller 205 drives the conveyor belt 206 to move. Subsequently, an item is placed on the top of the conveyor belt 206, and after all the items enter the inside of the detection frame 1, the output of the DC motor 201 is turned off to stop the movement of the conveyor belt 206. Subsequently, through the output of the first servo motor 208, the first lead screw 209 drives the first screw block 210 to move in the front-back direction. As the first screw block 210 moves, the L-shaped rod 211 and the moving frame 212 move synchronously, and the components in the moving frame 212 move synchronously with the X-ray probe 4 in the front-back direction. Subsequently, through the output of the second servo motor 213, the second lead screw 214 rotates, thereby driving the second screw block 215 to move in the left-right direction. At this time, the second screw block 215 drives the sliding block 216 and the X-ray probe 4 to move in the left-right direction synchronously, so that the X-ray probe 4 aligns with the item placed on the top of the conveyor belt 206 for detection and imaging work. When the detection is completed, the DC motor 201 outputs again to move the conveyor belt 206 and move the item on the top of the conveyor belt 206 out of the inside of the detection frame 1.

[0036] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
