Description

Technical Field

[0001] This invention relates to the field of high-voltage module integrated structure technology, specifically a micro X-ray source high-voltage module integrated structure based on carbon nanotube cold cathode. Background Technology

[0002] X-rays are a type of high-energy radiation that can be harmful to the human body. Due to the protection of Earth's atmosphere, X-rays in space are blocked and therefore rarely exist in the natural environment. Generally speaking, X-rays have very strong penetrating power, but different substances absorb them to varying degrees. Utilizing this characteristic, X-rays can be used to detect the internal structure, shape, and even composition of objects. Today, X-rays are widely used in fields such as medical imaging, security inspection, and industrial non-destructive testing.

[0003] According to Chinese Patent Publication No. CN117038419A, a carbon nanotube cold cathode microfocus X-ray tube is disclosed, relating to the field of vacuum micro-nanoelectronics technology. It includes a housing, a cathode electron emitting section, a grid structure, a focusing electrode, and an anode arranged sequentially from bottom to top inside the housing, and a X-ray exit window disposed on the housing. The centers of the cathode electron emitting section, the grid structure, the focusing electrode, the anode, and the X-ray exit window are all aligned on a straight line. The grid structure adopts a hexagonal honeycomb structure. By controlling the variable method to change the side length, thickness, and width of each hexagon in the hexagonal honeycomb structure, a uniform electric field is formed between the grid structure and the cathode electron emitting section under the action of a positive voltage. The focusing electrode adopts a curved structure, which matches the trajectory of electrons when focused. This invention has a simple structure, excellent focusing effect, high current, and smaller focal spot size.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] The invention will be further described below with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1-8 As shown, the integrated structure of the micro X-ray source high-voltage module based on carbon nanotube cold cathode of the present invention includes a voltage regulation structure 100, a housing 200, and a docking post 300. The voltage regulation structure 100 is installed inside the housing 200, and the docking post 300 is installed on the housing 200. The docking post 300 is electrically connected to the voltage regulation structure 100. By connecting the docking post 300 to the circuit, the device can be used. A circuit board is set inside the housing 200, and the docking post 300 is connected to the circuit board to provide power, which is then conducted to the voltage regulation structure 100. The circuit control is performed through the voltage regulation structure 100.

[0035] A voltage regulation structure 100 is used for voltage regulation. The anode ring 4 is the anode, and the carbon nanotube cold cathode 6 is the cathode. A grid mechanism 5 is set between the anode ring 4 and the carbon nanotube cold cathode 6 to control the current and voltage. The telescopic rod 11 is telescopically adjusted on the support rod 12. The position of the grid ring 9 and the grid rod 8 is changed by the docking ring 10 to adjust the height, thereby controlling the contact surface and performing greater current and voltage control. The pressing adjustment seat 15 is connected to the support rod 12 through the hydraulic seat 14 and the connecting seat 13 for adjusting the height of the telescopic rod 11. After adjusting to the appropriate position, the hydraulic seat 14 and the docking fixing screw 16 are fixed by turning the docking fixing screw 16. Several connecting columns 23 are provided and are electrically connected to the anode ring 4, the grid mechanism 5, and the carbon nanotube cold cathode 6 respectively.

[0036] The voltage regulation structure 100 includes a top shell 1, a vacuum protective shell 2, and an adjustment component 3. The vacuum protective shell 2 is fixedly mounted on the adjustment component 3, and the top shell 1 is fixedly mounted on the vacuum protective shell 2.

[0037] The regulating component 3 includes an anode ring 4, a gate mechanism 5, a carbon nanotube cold cathode 6, and a support mechanism 7. The carbon nanotube cold cathode 6 is fixedly located at the center of the support mechanism 7, and the anode ring 4 is fixedly located on the outer ring of the support mechanism 7. The gate mechanism 5 is located between the anode ring 4 and the carbon nanotube cold cathode 6. The lower end of the gate mechanism 5 is fixed to the support mechanism 7. The gate mechanism 5 has a telescopic adjustment function. The connecting post 23 is soldered to the circuit board. Through current control, the connecting post 23 is connected to the anode ring 4, the gate mechanism 5, and the carbon nanotube cold cathode 6 respectively, so that the carbon nanotube cold cathode 6 is the cathode, the anode ring 4 is the anode, and the gate mechanism 5 is located between the anode ring 4 and the carbon nanotube cold cathode 6. It can control the anode and cathode on the gate mechanism 5, thereby changing the movement of internal ions, thereby achieving the purpose of controlling the circuit. When the gate mechanism 5 is the cathode, it repels the ions on the carbon nanotube cold cathode 6, so that the ions do not reach the anode ring 4. When the gate mechanism 5 is the anode, it can adsorb the ions, so that the ions reach the anode ring 4 faster, forming a passage structure, while controlling the current and voltage.

[0038] The gate mechanism 5 includes a gate rod 8, a gate ring 9, a docking ring 10, a telescopic rod 11, a support rod 12, a connecting seat 13, a hydraulic seat 14, a pressing adjustment seat 15, and a docking fixing screw 16. The lower end of the hydraulic seat 14 is telescopically connected to the pressing adjustment seat 15, and the pressing adjustment seat 15 is provided with a docking fixing screw 16. The docking fixing screw 16 is tightly connected to the hydraulic seat 14 by rotation. The side end of the hydraulic seat 14 is connected to the connecting seat 13, and the side end of the connecting seat 13 is connected to several support rods 12. The support rods 12 are telescopically equipped with telescopic rods 11, and the upper end of the telescopic rods 11 is fixedly connected to the docking ring 10. The gate rod 8 is fixedly connected to the docking ring 10, and the gate ring 9 is fixedly connected to the gate rod 8. The housing 200 facilitates the support of the voltage regulation structure 100. The voltage regulation structure 100 is connected to the docking end post 300 through a circuit board to perform current and voltage regulation. The voltage regulation structure 100 consists of a top shell 1, a vacuum... The protective shell 2 and the adjusting component 3 are combined to form a vacuum structure. The top shell 1, the vacuum protective shell 2, and the adjusting component 3 are connected to the anode ring 4, the grid mechanism 5, and the carbon nanotube cold cathode 6, respectively. The anode ring 4 is the anode, and the carbon nanotube cold cathode 6 is the cathode. The grid mechanism 5 can adjust the anode and cathode properties through circuit changes, thereby controlling the ions passing through the anode ring 4 and the carbon nanotube cold cathode 6 to achieve the purpose of current and voltage regulation. At the same time, pressing the adjusting seat 15 changes the pressure in the hydraulic seat 14, so that the hydraulic seat 14 controls the telescopic rod 11 to move on the support rod 12 through the connecting seat 13, changing the height of the grid rod 8 and the grid ring 9, thereby achieving the purpose of control. After the position is determined, the hydraulic seat 14 and the pressing adjusting seat 15 are fixed by turning the connecting fixing screw 16 to prevent subsequent displacement problems. Thus, the grid mechanism 5 can be adjusted according to the actual use to control the movement of internal ions.

[0039] The supporting mechanism 7 includes an anode seat 17, a base 18, a gate groove 19, an anode docking groove 20, a support seat 21, an insulating protective seat 22, and a connecting post 23. The upper end of the insulating protective seat 22 is fixedly connected to the support seat 21. The center of the support seat 21 has an anode docking groove 20. The outer side of the anode docking groove 20 has a gate groove 19. The outer side of the gate groove 19 has an anode seat 17. The lower end of the anode seat 17 is fixed to the base 18. The bottoms of the anode seat 17, the gate groove 19, and the anode docking groove 20 are respectively connected to the connecting post 23. Before installation, the gate mechanism 5 needs to be adjusted. The height should be adjusted according to the actual usage. When the adjustment range is large, press the adjustment seat 15. Pressing the adjusting seat 15 against the hydraulic seat 14 changes the internal pressure of the hydraulic seat 14. This allows the hydraulic seat 14 to control the internal pressure of the support rod 12 via the connecting seat 13, thus controlling the extension of the telescopic rod 11. This, in turn, pulls the docking ring 10 to move, causing the docking ring 10 to drive the gate rod 8 and gate ring 9 to adjust their height. At this time, the gate rod 8 moves and adjusts on the gate groove 19 to perform height stretching. Then, the hydraulic seat 14 and the pressing adjusting seat 15 are fixed by the docking fixing screw 16, allowing for debugging. When the adjustment is small, the position of the pressing adjusting seat 15 is controlled according to the actual situation, and then the docking fixing screw 16 is tightened to determine the position of the gate rod 8 and gate ring 9, achieving the purpose of adjustment and control.

[0040] The carbon nanotube cold cathode 6 is fixed on the anode docking groove 20, the anode ring 4 is fixed on the anode seat 17, the support rod 12 is fixed on the gate groove 19, and the connecting seat 13, the hydraulic seat 14, and the pressing adjustment seat 15 are fixed on the lower end of the insulating protective seat 22.

[0041] The top shell 1, vacuum protective shell 2, and adjustment component 3 constitute a vacuum environment. The voltage adjustment structure 100 is connected to the circuit board inside the outer shell 200 through the connecting post 23, and the circuit board is connected to the docking end post 300.

[0042] The working principle is as follows: When in use, simply connect the docking terminal 300 to the circuit to use the device. The circuit board is set inside the housing 200. The docking terminal 300 is connected to the circuit board to provide power, which is then conducted to the voltage regulation structure 100. The circuit control is performed through the voltage regulation structure 100.

[0043] The connecting post 23 is soldered to the circuit board. Through current control, the connecting post 23 is connected to the anode ring 4, the gate mechanism 5, and the carbon nanotube cold cathode 6 respectively, so that the carbon nanotube cold cathode 6 is the cathode, the anode ring 4 is the anode, and the gate mechanism 5 is located between the anode ring 4 and the carbon nanotube cold cathode 6. It can control the anode and cathode on the gate mechanism 5, thereby changing the movement of internal ions and achieving the purpose of controlling the circuit. When the gate mechanism 5 is the cathode, it repels the ions on the carbon nanotube cold cathode 6, so that the ions do not reach the anode ring 4. When the gate mechanism 5 is the anode, it can adsorb the ions, so that the ions reach the anode ring 4 faster and form a passage structure, while controlling the current and voltage.

[0044] Before installation, the gate mechanism 5 needs to be debugged. The height needs to be adjusted according to actual usage. When the adjustment range is large, press the adjusting seat 15. The adjusting seat 15 will then fit against the hydraulic seat 14, changing the pressure inside the hydraulic seat 14. This allows the hydraulic seat 14 to control the pressure inside the support rod 12 via the connecting seat 13, controlling the extension rod 11 to extend, thereby pulling the docking ring 10. This causes the docking ring 10 to drive the gate rod 8 and gate ring 9 to adjust their height. At this time, the gate rod 8 moves and adjusts on the gate groove 19, undergoing height stretching. Then, the hydraulic seat 14 and the adjusting seat 15 are fixed using the docking fixing screw 16, allowing for debugging. When the adjustment is small, the position of the adjusting seat 15 is controlled according to actual usage, and then the docking fixing screw 16 is tightened to determine the position of the gate rod 8 and gate ring 9, achieving the purpose of adjustment control.

[0045] Example 2

[0046] Based on Example 1, such as Figure 9 As shown, a communication control unit 24 is fixedly installed on the connecting post 23. The communication control unit 24 includes a sleeve frame 25, a fixed sleeve 26, and an insulating connecting ring 27. The fixed sleeve 26 is fixedly installed on the insulating connecting ring 27, and the sleeve frame 25 is fixedly installed on the upper end of the fixed sleeve 26. The connection control unit 24 facilitates docking and adjustment. The connecting post 23 is connected to the guide connecting post 28 through the sleeve frame 25. The lower end of the guide connecting post 28 can be rotated and adjusted by rotating the sleeve ring 30 and the mating pin 31, thereby changing the angle and position of the mating pin 31. It is connected to the circuit board through the connecting seat 13 to provide the power required by the equipment, thereby performing current and voltage control. At the same time, the carbon nanotube cold cathode 6 adopts a carbon nanotube cold cathode setting, which can respond faster and facilitate current and voltage adjustment.

[0047] The communication control unit 24 also includes a guide communication post 28, a rotating sleeve shaft 29, a rotating collar 30, and a mating pin 31. The lower end of the fixed sleeve 26 is fixed to the rotating sleeve shaft 29. The center of the rotating sleeve shaft 29 is fixedly provided with the guide communication post 28. The lower end of the guide communication post 28 is fixedly provided with the rotating collar 30. The lower end of the rotating collar 30 is fixedly connected to the mating pin 31. The rotating collar 30 rotates and adjusts at the lower end of the rotating sleeve shaft 29.

[0048] The sleeve frame 25 is sleeved with the connecting post 23 and subsequently reinforced by welding. The connecting post 23 is connected with the guide connecting post 28 to guide the current. The rotating collar 30, in conjunction with the rotation of the pin 31, adjusts the connection position with the circuit board.

[0049] In use, the connection control unit 24 is placed at the lower end of the connecting post 23 and fixed by soldering. At this time, the connecting post 23 is in contact with the sleeve frame 25 and docks with the guide connecting post 28 in the fixed sleeve 26. The current is conducted to the guide connecting post 28 through the mating pin 31 and the rotating collar 30, thereby achieving the purpose of current diversion. At this time, the mating pin 31 can move on the rotating sleeve shaft 29 through the rotating collar 30, changing the position of the mating pin 31, which is convenient for adjusting the connection point position according to the actual use. The fixed sleeve 26 and the insulating connecting ring 27 are set to facilitate insulation protection. The multiple connecting posts 23 are connected and tightened to improve the connection stability.
