Description

Technical Field

[0001] This utility model relates to the field of X-ray imaging technology, and more specifically to an X-ray imaging device. Background Technology

[0002] X-ray imaging devices are essential medical imaging tools that utilize X-rays and are widely used in clinical diagnosis. These devices primarily include conventional X-ray machines, computed tomography (CR) systems, digital radiography (DR) systems, and CT scanners. Beyond medical applications—using various techniques to acquire two-dimensional or three-dimensional images of the human body to aid in accurate diagnoses—they are also used in manufacturing processes, such as for inspecting weld seams in plates.

[0003] For example, in the prior art publication number CN218481441U, there is a tube sheet weld detector composed of multiple image sensors. The image sensing module of this utility model consists of four groups of image sensors, and each group of image sensors is further composed of N image sensors. Therefore, the value of N can be adjusted according to the size of the tube sheet to be detected.

[0004] However, the above-mentioned existing technology still has the following problems when used: when manually adjusting the X-ray imaging device, manual operation takes time, resulting in low shooting efficiency. Based on this, the present invention provides an automatically rotating X-ray imaging device. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides an X-ray imaging device that uses a hollow rotating platform to drive four image sensors to rotate, performing two imaging operations. This method is more efficient, and because it is electrically controlled, the rotation accuracy is higher, which is more conducive to the implementation of stitching algorithms and results in more accurate images. The use of a ring plate and a rubber sealing ring to cooperate in sealing between the rotating component and the hollow rotating platform prevents dust from affecting the rotation accuracy of the rotating component, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an X-ray imaging device, comprising a hollow rotating platform, a rotating component on the top of the hollow rotating platform, an X-ray imaging assembly fixedly mounted on the top of the rotating component, the X-ray imaging assembly comprising four image sensors arranged in a circular array around the central axis of the hollow rotating platform, a cover plate fitted over the four image sensors on the outside of the hollow rotating platform, a plurality of spring pins fixedly passing through the outer wall of the cover plate, and slots adapted to the spring pins being opened on the outer wall surface of the rotating component, the spring pins being inserted into the slots.

[0007] In a preferred embodiment, an annular plate is fixedly sleeved on the outer wall of the rotating component, and a rubber sealing ring is provided between the inner wall of the annular plate and the hollow rotating platform. The annular plate and the rubber sealing ring play a sealing role between the rotating component and the hollow rotating platform, thereby preventing dust and debris from clogging the gap between the rotating component and the hollow rotating platform.

[0008] In a preferred embodiment, the inner wall of the cover plate is provided with an annular groove, and the annular plate is disposed inside the annular groove to prevent the annular plate from obstructing the rotation of the cover plate.

[0009] In a preferred embodiment, the outer wall surface of the cover plate has multiple openings, and a metal heat-conducting plate is fixedly installed inside each opening. The inner wall of the metal heat-conducting plate is in contact with the outer wall of the rotating part, and the heat on the rotating part and the hollow rotating platform is conducted to the outside by the metal heat-conducting plate, thereby realizing the heat dissipation of the rotating part and the hollow rotating platform.

[0010] In a preferred embodiment, a manual rotation component is fixedly provided at the top of the rotating component. The manual rotation component includes a circular plate, which is fixed at the top of the rotating component. The bottoms of the four image sensors are all fixed to the top of the circular plate. By grasping the cover plate, the cover plate can be manually rotated to adjust the angle of the image sensors.

[0011] In a preferred embodiment, the outer wall of the front end of the cover plate is threaded with a bolt, and the rear end of the bolt penetrates the cover plate and contacts the outer wall of the hollow rotating platform, so that the cover plate can be easily fixed by using bolts.

[0012] In a preferred embodiment, mounting holes are provided at all four corners of the top of the hollow rotating platform.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a hollow rotating platform to drive four image sensors to rotate and take two pictures, which is more efficient. Since it is electrically controlled, the rotation accuracy is higher, which is more conducive to the implementation of the stitching algorithm and the captured pictures are more accurate. The ring plate and rubber sealing ring cooperate to seal between the rotating parts and the hollow rotating platform, preventing dust from affecting the rotation accuracy of the rotating parts.

[0015] 2. The cover plate is easily installed and removed using a spring pin, and bolts are used to fix the cover plate. Loosening the bolts separates the cover plate from the rotating part, allowing the cover plate to be manually grasped and the rotating part to be rotated, thereby manually adjusting the angle of the X-ray imaging component, as an emergency backup.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Refer to the instruction manual appendix Figure 1-5 This utility model provides an X-ray imaging device, including a hollow rotating platform 1. The top of the hollow rotating platform 1 is provided with a rotating component 2. The top of the rotating component 2 is fixedly provided with an X-ray imaging assembly 3. The X-ray imaging assembly 3 includes four image sensors 301, which are arranged in a ring array around the central axis of the hollow rotating platform 1.

[0026] Next, a cover plate 4 is fitted on the outside of the hollow rotating platform 1, and the cover plate 4 is fitted on the outside of the four image sensors 301. Multiple spring pins 5 are fixedly inserted through the outer wall of the cover plate 4. The outer wall surface of the rotating part 2 is provided with a slot 6 that matches the spring pins 5. The spring pins 5 are inserted into the slot 6.

[0027] Furthermore, an annular plate 7 is fixedly sleeved on the outer wall of the rotating component 2, and a rubber sealing ring 8 is provided between the inner wall of the annular plate 7 and the hollow rotating platform 1. The annular plate 7 and the rubber sealing ring 8 play a sealing role between the rotating component 2 and the hollow rotating platform 1, thereby preventing dust and debris from clogging the gap between the rotating component 2 and the hollow rotating platform 1. An annular groove 9 is provided on the inner wall of the cover plate 4, and the annular plate 7 is located inside the annular groove 9 to prevent the annular plate 7 from hindering the rotation of the cover plate 4.

[0028] Moreover, multiple openings 10 are provided on the outer wall surface of the cover plate 4, and a metal heat-conducting plate 11 is fixedly installed inside each opening 10. The inner wall of the metal heat-conducting plate 11 is in contact with the outer wall of the rotating part 2. The heat on the rotating part 2 and the hollow rotating platform 1 is conducted to the outside by the metal heat-conducting plate 11, thereby realizing the heat dissipation of the rotating part 2 and the hollow rotating platform 1.

[0029] The hollow rotating platform 1 has mounting holes 13 at each of its four corners at the top, which are used to firmly fix the hollow rotating platform 1 in use.

[0030] In use, first fix the hollow rotating platform 1, and then use the hollow rotating platform 1 to drive the four image sensors 301 to rotate and take two pictures. The efficiency is higher. Since it is electrically controlled, the rotation accuracy is higher, which is more conducive to the implementation of the stitching algorithm. The pictures are more accurate. The image sensors 301 transmit the captured image signals to the main control board, and the main control board then transmits the acquired image signals to the PC. The PC is then used to display and process the images.

[0031] The cover plate 4 is inserted into the slot 6 on the rotating part 2 via multiple spring pins 5, facilitating the installation and removal of the cover plate 4 for maintenance of the image sensor 301. A ring plate 7 is installed between the cover plate 4 and the rotating part 2. The ring plate 7, in conjunction with a rubber sealing ring 8, provides a seal between the rotating part 2 and the hollow rotating platform 1, preventing dust and debris from clogging the gap between them and reducing resistance. Figure 1-2 As shown in Figures 5 and 6, the square holes on the cover plate 4 correspond to the holes at the center of the splicing of multiple image sensors 301.

[0032] Refer to the instruction manual appendix Figure 1-5 The top of the rotating component 2 is fixedly provided with a manual rotation assembly 12. The manual rotation assembly 12 includes a circular plate 1201. The circular plate 1201 is fixed to the top of the rotating component 2. The bottoms of the four image sensors 301 are all fixed to the top of the circular plate 1201. By grasping the cover plate 4, the cover plate 4 can be manually rotated to adjust the angle of the image sensor 301.

[0033] The outer wall of the front end of the cover plate 4 is threaded with a bolt 1202. The rear end of the bolt 1202 passes through the cover plate 4 and contacts the outer wall of the hollow rotating platform 1. The bolt 1202 is used to fix the cover plate 4.

[0034] By setting bolts 1202 on the cover plate 4, when the cover plate 4 is connected to the rotating part 2 by tightening the bolts 1202, the X-ray imaging component 3 and the cover plate 4 can be rotated together by the hollow rotating platform 1, thereby adjusting the angle of the X-ray imaging component 3. When the bolts 1202 are loosened, the cover plate 4 is separated from the rotating part 2. When the hollow rotating platform 1 malfunctions, the cover plate 4 can be grabbed to rotate the rotating part 2 together, thereby manually adjusting the angle of the X-ray imaging component 3 as an emergency backup.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
