Description

Technical Field

[0001] The present invention relates to the technical field of X-ray, and particularly to a detection system and a performance detection method for an X-ray generating device. Background Art

[0002] As an X-ray output source, the X-ray tube generates X-rays that can be used for non-destructive testing of the interior of an object and is widely used in various fields such as medical treatment, security inspection, and industrial flaw detection. The X-ray tube generates electrons at the cathode, accelerates them to high speed through the high-voltage electric field between the cathode and anode, and then hits the anode target surface. X-rays are generated through the bremsstrahlung mechanism. The external high voltage outputs a stable high-voltage electric field between the cathode and anode through a high-voltage power supply, and the external housing is vacuum-sealed to provide a high-vacuum environment, enabling the electron impact event to operate continuously and stably, and finally obtaining continuously and stably output X-rays.

[0003] Due to the characteristics of small focus and small dose of the micro-focus X-ray tube, the window material of it is a beryllium window with a small wall thickness. Beryllium is highly toxic to the human body and requires strict control during the processing. Secondly, due to the beryllium window being too thin, its surface should not be touched during the entire production process of the X-ray tube to avoid deformation or damage, which may affect the performance of the X-ray tube.

[0004] The X-ray tube belongs to an electric vacuum device. After the entire tube is produced, it is necessary to detect the performance of the X-ray tube. Usually, the X-ray tube is immersed in transformer oil for detection. The external power supply is connected to both ends of the X-ray tube through wires. After the test is completed, the X-ray tube is taken out from the oil tank, and then the oil stain on its surface is cleaned and removed. Similarly, before the X-ray tube is assembled into an integrated X-ray generating device, it is also necessary to confirm the performance quality of the X-ray tube first to avoid rework due to problems with the X-ray tube after being assembled into the whole machine. Before the X-ray tube is assembled into the X-ray generating device, the performance of the X-ray tube must also be detected and confirmed. As described above, this detection also requires immersing the entire X-ray tube in transformer oil and then connecting a high-voltage power supply for testing.

[0005] The above tests all monitor the integrity of the quality of the X-ray tube by collecting the tube voltage, tube current of the X-ray tube, and whether there are any faults during the operation process, and cannot directly reflect the effect of the X-ray tube at the actual application end, that is, the effect of the final X-ray transmission image. Moreover, after the test is completed, the main purpose of cleaning the X-ray tube is to remove the transformer oil on the surface of the X-ray tube. If the entire X-ray tube is immersed in transformer oil, once accidentally touched during the cleaning process, it is very easy to cause deformation or even damage to the window, and finally lead to the failure of the X-ray tube and it cannot be used. In addition, due to the high toxicity of beryllium to the human body, special control is required. If the X-ray tube is immersed in transformer oil and cleaning solution, the beryllium window of the X-ray tube comes into contact with the immersed solution, there is a risk of beryllium contaminating the solution, which is not conducive to environmental protection.

[0006] In addition, when developing or repairing and testing the power supply that is matched with the X-ray tube, it is also necessary to perform performance tests on various types of board components to confirm whether their performance meets the requirements. Currently, when assembling the high-voltage power supply board components in the form of a whole machine, the disassembly steps are complex and the work efficiency is low. Once a problem occurs with the board components, it is very difficult to troubleshoot.

[0007] Therefore, how to improve the accuracy and safety of X-ray tube detection, reduce the damage to the X-ray tube during the detection process, and at the same time improve the convenience of testing the high-voltage power supply board components has become one of the problems that need to be urgently solved by those skilled in the art.

[0008] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the present application and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art just because these solutions are described in the background art part of the present application.

[0062] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0063] Please refer to Figures 1 to 2 . It should be noted that the illustrations provided in this embodiment only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0064] The present invention proposes a method for detecting the performance of an X-ray tube and a high-voltage power supply board. For the X-ray tube, detection is performed before the X-ray tube is stored in the warehouse and before the X-ray generating device is installed, to ensure that the performance of the X-ray tube meets the usage requirements. For the high-voltage power supply board, performance detection is performed during the development of the board and when fault repair is confirmed, in order to confirm the state of the board. The specific solution is as follows:

[0065] As Figure 1 and Figure 2 shown, the present invention provides a detection system for an X-ray generating device. The detection system for the X-ray generating device includes:

[0066] An oil tank 1, a tubular mounting bracket 2, a horizontal support block 7a, a vertical support block 7b, a detector 3, an X-ray tube 4, and a high-voltage power supply board 5.

[0067] As Figure 1 and Figure 2 shown, the oil tank 1 includes a cover plate 11 and a box body 12. The cover plate 11 is hermetically connected to the top opening of the box body 12; the oil tank 1 contains transformer oil 13 and is provided with a core mounting port on the side.

[0068] Specifically, the top opening of the box body 12 is used for filling the transformer oil 13, and the transformer oil 13 plays an insulating role. The cover plate 11 and the box body 12 are sealed with a sealing structure to ensure that the inside of the oil tank 1 is not affected by the external environment, so as to maintain the long-term use performance of the transformer oil 13. In this embodiment, in order to prevent the transformer oil 13 from overflowing, the transformer oil 13 does not fill the oil tank 1; further, the space in the oil tank 1 that is not filled with the transformer oil 13 is evacuated to a vacuum. As an example, the vacuum negative pressure is between -0.095 Mpa and -0.1 Mpa, so that the insulating performance of the transformer oil 13 can maintain long-term effectiveness.

[0069] Specifically, a power interface 111 is provided on the cover plate 11 for supplying power to the components inside the fuel tank 1. A sealing arrangement is also required between the power interface 111 and the cover plate 11 to maintain the long-term performance of the transformer oil 13. In actual use, the power interface 111 can be set at any position as required, not limited to this embodiment.

[0070] Specifically, in this embodiment, the cover plate 11 is removable to facilitate the filling of the transformer oil 13 and the arrangement of the components inside the fuel tank 1. As an example, the cover plate 11 is also connected to an automatic lifting device (not shown in the figure) for easy operation.

[0071] Specifically, as an example, the cover plate 11 and the box body 12 are made of a transparent plastic material, including but not limited to plexiglass. Firstly, it serves as an insulating function; secondly, it is convenient for observing the plate components, and it can be directly observed when the high-voltage power supply plate component 5 ignites; in actual use, any material that can meet the requirements is applicable to the present invention.

[0072] As Figure 1 and Figure 2 shown, the anode 42 of the X-ray tube 4 passes through the tubular mounting bracket 2 and is immersed in the transformer oil 13, and the cathode and beryllium window 41 of the X-ray tube 4 are arranged in the external environment. The position of the X-ray tube 4 can be adjusted through the bellows 22, greatly improving the flexibility.

[0073] Specifically, the X-ray tube 4 is a single-ended anode X-ray tube, and the high voltage is all applied through the anode. The cathode part is a low-voltage power supply and can be connected separately in the air environment. The high-voltage part at the anode end must be led out in an insulating medium, otherwise there will be a breakdown discharge phenomenon and detection cannot be carried out. Therefore, in the present invention, the anode of the X-ray tube 4 is immersed in the transformer oil for insulation treatment.

[0074] As Figure 1 and Figure 2 shown, the tubular mounting bracket 2 includes a first mounting portion 21, a bellows 22, and a second mounting portion 23. The first mounting portion 21 is hermetically fixed to the outer side of the fuel tank 1 and is aligned with the tube core mounting opening; the second mounting portion 23 is hermetically connected to the cathode end housing of the X-ray tube 4; one end of the bellows 22 is connected to the first mounting portion 21, and the other end is connected to the second mounting portion 23.

[0075] Specifically, in this embodiment, the first mounting portion 21 is fixed to the fuel tank 1 by screws and sealed by a sealing structure; the second mounting portion 23 is fastened to the X-ray tube 4 by screws and sealed by a sealing structure; to prevent the transformer oil 13 from leaking out. The bellows 22 is telescopic and can freely adjust its orientation and length as needed. The flexibility is greatly improved.

[0076] As Figure 1 and Figure 2 shown, the second mounting portion 23 is connected to the horizontal support block 7a so that the X-ray tube 4 is in a horizontal placement state; or the second mounting portion 23 is connected to the vertical support block 7b so that the X-ray tube 4 is in a vertical placement state.

[0077] Specifically, as Figure 1 shown, when the detection system of the X-ray generating device is in a test state, the horizontal support block 7a is fixed to the outer side wall of the fuel tank 1, that is, one end of the horizontal support block 7a is fixed to the fuel tank 1 and the other end is fixed to the second mounting portion 23, so that the X-ray tube 4 is in a horizontal placement state.

[0078] Specifically, as Figure 2 shown, when the detection system of the X-ray generating device is in a state of replacing the X-ray tube 4, the vertical support block 7b is fixed to the ground, that is, one end of the vertical support block 7b is fixed to the ground and the other end is fixed to the second mounting portion 23, so that the X-ray tube 4 is in a vertical placement state, and the height of the second mounting portion 23 is higher than the oil level of the transformer oil 13 in the fuel tank 1, so that the transformer oil 13 will not flow out during disassembly.

[0079] It should be noted that, in this embodiment, the vertical support block 7b is a split structure in two halves, which is convenient for putting in and taking out the X-ray tube 4. When the X-ray tube 4 is in a vertical placement state, due to the tensile elastic force of the bellows 22, the support block 7b can be clamped, and there is no need for threaded fastening between the vertical support block 7b and the second mounting portion 23. When the X-ray tube 4 is in a horizontal placement state, the bellows 22 and the wire 6 become horizontal; when the X-ray tube 4 is in a vertical placement state, the bellows 22 and the wire 6 become vertical, and other structures remain unchanged.

[0080] As Figure 1 and Figure 2 shown, the high-voltage power supply board 5 is immersed in the transformer oil 13 in the fuel tank 1 through the high-voltage power supply board mounting bracket 51. The power supply end of the high-voltage power supply board 5 is connected to the power interface 111, and the high-voltage output end is connected to the anode of the X-ray tube 4.

[0081] Specifically, in this embodiment, the high-voltage power supply board mounting bracket 51 is disposed on the lower surface of the cover plate 11, and is used to stably suspend the high-voltage power supply board 5 in the transformer oil 13, so that the distances between the high-voltage power supply board 5 and all directions of the fuel tank 1 meet the high-voltage insulation requirements (the specific distances are set according to actual situations), and to avoid breakdown and arcing phenomena. The high-voltage power supply board mounting bracket 51 rises and falls following the rise and fall of the cover plate 11. By rising the cover plate 11, the high-voltage power supply board mounting bracket 51 and the high-voltage power supply board 5 can be taken out from the fuel tank 1, thereby facilitating the replacement of the high-voltage power supply board 5 and avoiding operations such as line connection in the transformer oil 13 to contaminate the transformer oil.

[0082] Specifically, the high-voltage power supply board 5 is electrically connected to the X-ray tube 4 through a wire 6. As an example, the wire 6 is a retractable spiral shape and can be retracted or extended as needed, with great flexibility.

[0083] As Figure 1 and Figure 2 shown, the detector 3 is disposed in the X-ray emission direction of the X-ray tube 4.

[0084] Specifically, in this embodiment, the detector 3 is vertically disposed and is fixed and adjusted in position (including but not limited to height and distance) through a detector mounting bracket 31. In actual use, the distance between the detector 3 and the X-ray tube 4 can be set according to needs (including but not limited to magnification ratio and radiation area size).

[0085] The present invention also provides a performance detection method for an X-ray generating device. The performance detection method for the X-ray generating device includes:

[0086] 1) Provide a detection system for the X-ray generating device, fix the second mounting portion 23 of the tubular mounting bracket 2 at a position higher than the oil level of the transformer oil 13 in the fuel tank 1, place the anode of the X-ray tube 4 in the tubular mounting bracket 2, and hermetically connect the cathode end housing of the X-ray tube 4 to the second mounting portion 23.

[0087] Specifically, as Figure 2 shown, in this embodiment, the vertical support block 7b is used to mount the X-ray tube 4; when the X-ray tube 4 needs to be replaced, the same method is adopted, which will not be elaborated here one by one.

[0088] 2) Subsequently, fix the second mounting portion 23 on the side of the fuel tank 1, so that the X-ray tube 4 is in a horizontal placement state, place the detector 3 in the X-ray emission direction of the X-ray tube 4, and place the object to be measured between the X-ray tube and the detector.

[0089] Specifically, as Figure 1 shown, after the X-ray tube 4 is installed, adjust the X-ray tube 4 to a horizontal placement state. At this time, it is achieved by using the horizontal support block 7a.

[0090] Specifically, the object to be measured is placed in the middle of the X-ray tube 4 and the detector 3, and its specific position can be adjusted arbitrarily based on the requirements of the magnification factor.

[0091] 3) The high-voltage power supply board 5 generates high voltage. The X-ray tube 4 emits X-rays under the action of the high voltage. The detector 3 collects the X-rays passing through the object to be measured and forms a corresponding image, and judges the performance of the X-ray generating device according to the collected image.

[0092] It should be noted that the performance of the X-ray generating device described in the present invention refers to the performance of the X-ray tube 4 and the high-voltage power supply board 5.

[0093] Specifically, as an example, confirm whether there are artifacts in the X-ray emission of the X-ray tube by whether there are abnormal black dots or black blocks in the image. As another example, confirm the X-ray dose by the gray value of the image; further, adjust the voltage value of the high voltage generated by the high-voltage power supply board 5, load and expose the X-rays, and then confirm the state of the high-voltage power supply board 5 based on the gray value of the image (that is, the gray value of the image is positively correlated with the voltage value of the high voltage). As yet another example, set the object to be measured as a resolution test card (JIMA), and determine the focal spot size of the X-ray tube 4 based on the image of the resolution test card collected by the detector 3.

[0094] It should be noted that the entire detection device is placed in a lead room or a lead box to prevent X-rays from causing harm to the detection personnel. The detection system of the X-ray generating device can also be used as an X-ray detection device for detecting various parts, products and other materials, which will not be elaborated here one by one.
