Description

Technical Field

[0001] This invention relates to the field of X-ray inspection, and more specifically to a dedicated leak detection device and method for X-ray tube assemblies. Background Technology

[0002] An X-ray tube is a vacuum component that operates under high voltage. It is widely used in medicine for diagnosis and in industrial technology for non-destructive testing of materials, structural analysis, spectral analysis, and film exposure. During the operation of an X-ray tube, a special channel is used to extract X-rays to irradiate objects and obtain images. In the process of extracting X-rays, materials such as lead are needed to shield against X-ray leakage from other directions, which could harm the surrounding human body. Therefore, after the X-ray tube is manufactured, the manufacturer needs to conduct a leakage test on the X-ray tube to ensure that there is no leakage problem.

[0003] The currently disclosed Chinese patent CN202221981548.5 discloses a device for X-ray leakage testing of a X-ray tube, which includes a rotating assembly, a carriage guide assembly, and a C-arm assembly. The rotating assembly is mounted on the ground via a base, and the C-arm assembly is fixed to the ground via a column square tube. The C-arm in the C-arm assembly is semi-circular, and the rotating assembly is located at one end of the C-arm. The output end of the rotating assembly is arranged radially along the C-arm and faces the center of the semi-circular ring formed by the C-arm. The carriage guide assembly is mounted on the ground, located diagonally in front of the rotating assembly, and faces parallel to the output end of the rotating assembly.

[0004] According to the aforementioned patent, the patent ensures that all positions of the X-ray tube under test, except for the emission port that emits X-rays, are exposed within the coverage area of ​​the X-ray detector mounted on the C-arm when the tube rotates with the rotating shaft, thus ensuring that the presence of leaking X-rays can be detected at all positions. However, this patent cannot guarantee comprehensive detection of the X-rays emitted by the X-ray tube assembly, and there are still cases where leaking X-rays are not detected, resulting in incomplete detection. Therefore, there is currently a need for a detection device that can comprehensively detect leaking X-rays. Summary of the Invention

By moving and rotating the X-ray tube assembly body along a circular track, the straight radiation emitted from inside the tube and the straight radiation emitted from outside the tube body can be detected by the first radiation sensor and the second radiation sensor, respectively, thereby improving the detection effect.

[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present invention provides a dedicated leakage detection device for X-ray tube assemblies, comprising a base frame for mounting the X-ray tube assembly body, an annular track on the base frame, a slider on the annular track, the X-ray tube assembly body mounted on the slider, a sliding driver on the base frame for driving the slider to slide along the annular track, a rotation driver on the slider for driving the X-ray tube assembly body to rotate, a ring coaxial with the annular track on the base frame, a plurality of first X-ray sensors evenly distributed along the circumference of the ring, the working end of each first X-ray sensor facing outward, the working end of the X-ray tube assembly body facing the working end of the first X-ray sensor, a plurality of bars evenly distributed in the ring, a plurality of second X-ray sensors evenly spaced along the length of each bar, the working end of each second X-ray sensor facing outward, and a distance control component on the base frame for driving the movement of the plurality of bars to control the distance between the second X-ray sensors and the X-ray tube assembly body.

[0008] Preferably, the sliding driver has a ring-shaped rotating frame, which is rotatably mounted on the base frame. The rotating frame and the ring are coaxial. A first bearing is connected between the rotating frame and the inner side of the base frame, and a second bearing is connected between the rotating frame and the outer side of the base frame. A first rotary motor for driving the rotating frame to rotate is provided on the base frame. The ring is fixedly connected to the rotating frame. There are multiple X-ray tube assembly bodies, which are evenly distributed along the circumference of the annular track. A slider for mounting each X-ray tube assembly body is provided on the annular track, and a connecting plate is fixedly connected between each slider and the rotating frame.

[0009] Preferably, the rotary driver is provided with a collar, which is fixedly mounted on the slider. A rotating ring is fixedly mounted at the tail end of the X-ray tube assembly body. The axis of the rotating ring is in the same plane as the axis of the working end of the first X-ray sensor. The rotating ring is coaxial and rotatably mounted in the collar. A third bearing is connected between the rotating ring and the collar. A gear is coaxially mounted and fixedly mounted on the rotating ring. A gear ring coaxial with the ring is fixedly mounted on the outer ring of the base frame. The gear and the gear ring mesh with each other.

[0010] Preferably, the distance control component includes a fixed ring, which is fixedly mounted on the base frame. The fixed ring is coaxial with the circular ring. Multiple bars are evenly distributed around the fixed ring, and one end of each bar is hinged to the fixed ring. The fixed ring has a hinge portion for hinged at the end of each bar. The distance control component also includes a movable ring, which is coaxial and movably mounted above the fixed ring. Each bar is connected to the movable ring, and the fixed ring is equipped with a movable driver for driving the movable ring to move vertically.

[0011] Preferably, a diaphragm is provided around the multiple bars, the diaphragm is fixedly connected to the inner side of each bar, and the lower end of the diaphragm is fixedly sleeved on a fixing ring.

[0012] Preferably, the connector is provided with an auxiliary rod, one end of which is fixedly connected to the bar, and the other end of which extends toward the fixed ring. The bar wall of the auxiliary rod is attached to the inner wall of the diaphragm. The connector is also provided with a push-pull rod, one end of which is hinged to the lower end of the auxiliary rod, and the other end of which extends upward and is hinged to the movable ring. The movable ring has a hinge portion for hinged at the end of each push-pull rod.

[0013] Preferably, the movable driver is provided with a threaded rod, which is coaxial and rotatably mounted on the fixed ring. The movable ring is threaded onto the threaded rod, and the fixed ring is provided with a second rotary motor for driving the threaded rod to rotate.

[0014] Preferably, the upper end of the threaded rod is fixedly fitted with an anti-disengagement ring to prevent the movable ring from sliding upward and disengaging from the threaded rod.

[0015] Preferably, the straight rays passing through the tube opening at the working end of the X-ray tube assembly body are directed toward and sensed by the first X-ray sensor.

[0016] Preferably, the straight rays passing through the tube opening at the working end of the X-ray tube assembly body are directed toward and sensed by the second X-ray sensor.

[0017] Secondly, based on the aforementioned dedicated X-ray leakage detection equipment, this invention further proposes a method for detecting X-ray leakage in X-ray tube assemblies, comprising the following steps:

[0018] S1. Debugging: Adjust the distance between the second X-ray sensor and the X-ray tube assembly body. Drive the movable ring to move vertically through the movable driver, which will drive the connected connector to move, thereby pushing multiple bars to swing on the fixed ring at the same time, causing the second X-ray sensor on the bar to move closer to or further away from the X-ray tube assembly body, until the second X-ray sensor is within the predetermined range for detecting leaked X-rays.

[0019] S2. Start: Start the sliding driver. The sliding driver drives the X-ray tube assembly body to revolve around the circular track while the X-ray tube assembly body maintains its own rotation.

[0020] S3. Detection: The straight rays emitted from the X-ray tube assembly are received by several first-ray sensors distributed in a circular array along the circumference of the ring; the leaking rays emitted outward through the tube wall from the X-ray tube assembly are received by several second-ray sensors distributed in a straight array at the center of the ring.

[0021] The advantages of this invention compared to the prior art are:

[0022] 1. This invention achieves comprehensive detection of leakage radiation from the X-ray tube assembly by moving and rotating the assembly body along a circular track, thereby enabling the direct radiation emitted from the tube and the direct radiation emitted from outside the tube to be detected by the first radiation sensor and the second radiation sensor, respectively. This improves the detection effect.

[0023] 2. This invention uses the rotation of the rotating frame to drive the slider to move in the annular track. With the arrangement of multiple X-ray tube assembly bodies in the annular track, multiple X-ray tube assembly bodies can be detected simultaneously by the first X-ray sensor, improving detection efficiency. Furthermore, the leakage X-ray emitted from the outside of the X-ray tube assembly body can be detected by the second X-ray sensor, achieving comprehensive detection of leakage X-rays and improving the detection effect.

[0024] 3. This invention utilizes the cooperation of gears and gear rings. As the slider moves along the circular track, the gears roll along the gear rings, thereby causing the X-ray tube assembly to rotate. This ensures that all leaked X-rays emitted from the X-ray tube assembly are irradiated onto the second X-ray sensor, guaranteeing that all leaked X-rays are detected and improving the detection effect.

[0025] 4. This invention uses the swing of the bar on the fixed ring to move the second X-ray sensor on the bar closer to or further away from the X-ray tube assembly body, so that the leakage X-ray emitted by the X-ray tube assembly body can be detected within the emission range, realizing the detection of the leakage X-ray emission distance, ensuring that the leakage X-ray is fully detected, and improving the detection accuracy.

Detailed Implementation

[0038] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] See Figures 1-6As shown, a dedicated leakage detection device for X-ray tube assemblies includes a base frame 1 for mounting the X-ray tube assembly body 2. The base frame 1 has an annular track 3, and a slider 31 is mounted on the annular track 3. The X-ray tube assembly body 2 is mounted on the slider 31. The base frame 1 has a sliding driver 32 for driving the slider 31 to slide along the annular track 3. The slider 31 has a rotary driver 33 for driving the X-ray tube assembly body 2 to rotate. The base frame 1 has a circular ring 41 coaxial with the annular track 3. Several first-ray sensors 4 are mounted on the circular ring 41. Sensors 4 are evenly distributed along the circumference of the ring 41. The working end of each first X-ray sensor 4 faces outward. The working end of the X-ray tube assembly body 2 faces the working end of the first X-ray sensor 4. Multiple bars 51 are evenly distributed in the ring 41. Multiple second X-ray sensors 5 are equally spaced along the length of each bar 51. The working end of each second X-ray sensor 5 faces outward. The base frame 1 is also equipped with a distance control component 6 for driving the movement of multiple bars 51 to control the distance between the second X-ray sensor 5 and the X-ray tube assembly body 2.

[0041] During X-ray leakage detection, the X-ray tube assembly 2 is rotated around the annular track 3 by the sliding driver 32. Since the X-ray source of the X-ray tube assembly 2 is directed towards the first X-ray sensor 4, several first X-ray sensors 4 on the ring 41 can detect the straight X-rays emitted from the tube. Furthermore, since the slider 31 is equipped with a rotary driver 33 that cooperates with the X-ray tube assembly 2, the X-ray tube assembly 2 rotates as it moves along the annular track 3. The X-rays emitted from the X-ray tube assembly 2 through the tube wall irradiate the second X-ray sensor 5, thus detecting the leakage of X-rays from the X-ray tube assembly 2. Through the arrangement of several first X-ray sensors 4 and several second X-ray sensors 5, both the straight X-rays inside and outside the tube emitted by the X-ray tube assembly 2 can be detected during its rotation, ensuring comprehensive leakage detection.

[0042] See Figures 3-8As shown, the sliding driver 32 is provided with a ring-shaped rotating frame 321. The rotating frame 321 consists of two inner and outer rings and a connecting rod that is fixedly connected to the two inner and outer rings. The rotating frame 321 is rotatably mounted on the base frame 1. The rotating frame 321 is coaxial with the ring 41. A first bearing 3211 is connected between the rotating frame 321 and the inner side of the base frame 1, and a second bearing 3212 is connected between the rotating frame 321 and the outer side of the base frame 1. A first rotary motor 322 is provided on the base frame 1 to drive the rotating frame 321 to rotate. The ring 41 is fixedly connected to the rotating frame 321. There are multiple X-ray tube assembly bodies 2, and each X-ray tube assembly body 2 is mounted on the annular track 3 by a separate slider 31. A connecting plate 311 is fixedly connected between each slider 31 and the rotating frame 321.

[0043] As the sliding driver 32 drives the X-ray tube assembly body 2 to move along the annular track 3, the first rotary motor 322 drives the rotating frame 321 to rotate, and the ring 41 rotates accordingly. The slider 31 moves in the annular track 3. Due to the arrangement of multiple X-ray tube assembly bodies 2 on the annular track 3, several first X-ray sensors 4 on the ring 41 can simultaneously detect multiple X-ray tube assemblies and detect the straight X-rays emitted from their tubes, thereby improving the detection efficiency.

[0044] See Figures 3-8 As shown, the rotary driver 33 is provided with a collar 331, which is fixedly mounted on the slider 31. The tail end of the X-ray tube assembly body 2 is fixedly provided with a rotating ring 332. The axis of the rotating ring 332 is in the same plane as the axis of the working end of the first X-ray sensor 4. The rotating ring 332 is coaxial and rotatably mounted in the collar 331. A third bearing 3321 is connected between the rotating ring 332 and the collar 331. A gear 333 is coaxially mounted and fixedly mounted on the rotating ring 332. A gear ring 334 coaxial with the ring 41 is fixedly mounted on the outer ring of the base frame 1. The gear 333 and the gear ring 334 mesh with each other.

[0045] As the X-ray tube assembly 2 moves along the annular track 3 on the slider 31, the X-ray tube assembly 2 is rotated within the collar 331 via the rotating ring 332. The gear 333 on the rotating ring 332 meshes with the outer gear ring 334 of the annular track 3, causing the gear 333 to rotate along the gear ring 334 as the slider 31 moves along the annular track 3. This rotation drives the X-ray tube assembly 2 to rotate, ensuring that all the emitted leakage rays are irradiated onto the second X-ray sensor 5, achieving comprehensive detection.

[0046] See Figures 3-10As shown, the distance control component 6 is provided with a fixed ring 61, which is fixedly mounted on the base frame 1. The fixed ring 61 is coaxial with the circular ring 41. Multiple bars 51 are evenly distributed around the fixed ring 61, and one end of each bar 51 is hinged to the fixed ring 61. The fixed ring 61 has a hinge part for hinged to the end of each bar 51. The distance control component 6 is also provided with a movable ring 62, which is coaxial and movably mounted above the fixed ring 61. A connector 621 is provided between each bar 51 and the movable ring 62. The fixed ring 61 is provided with a movable driver 63 for driving the movable ring 62 to move vertically.

[0047] When the distance control component 6 adjusts the distance between the second X-ray sensor 5 and the X-ray tube assembly body 2, in order to ensure that the emission of leaky X-rays can be detected by the second X-ray sensor 5, it is necessary to adjust the range between the two until the emission of leaky X-rays is detected. The distance at which the leaky X-rays are emitted is detected by the movable driver 63 driving the movable ring 62 to move vertically, thereby driving the connected connector 621 to move, thereby pushing multiple bars 51 to swing simultaneously on the fixed ring 61, causing the second X-ray sensor 5 on the bar 51 to gradually move closer to or away from the X-ray tube assembly body 2, thereby effectively detecting the emission range of leaky X-rays.

[0048] See Figures 3-10 As shown, a diaphragm 64 is provided around a plurality of bars 51. The diaphragm 64 is fixedly connected to the inner side of each bar 51, and the lower end of the diaphragm 64 is fixedly sleeved on a fixing ring 61.

[0049] When X-rays leak from the emitting tube of the X-ray tube assembly 2, in order to prevent X-rays from penetrating between two adjacent bars 51 and affecting the detection of the second X-ray sensor 5, a diaphragm 64 is set up so that when X-rays irradiate the diaphragm 64, it has an anti-penetration effect, so that the X-rays and the working end of the second X-ray sensor 5 are kept on the same plane, which is beneficial to the accurate detection of the second X-ray sensor 5.

[0050] See Figures 3-10 As shown, the connector 621 is provided with an auxiliary rod 6211. One end of the auxiliary rod 6211 is fixedly connected to the bar 51, and the other end of the auxiliary rod 6211 extends toward the fixed ring 61. The rod wall of the auxiliary rod 6211 is attached to the inner wall of the diaphragm 64. The connector 621 is also provided with a push-pull rod 6212. One end of the push-pull rod 6212 is hinged to the lower end of the auxiliary rod 6211, and the other end of the push-pull rod 6212 extends upward and is hinged to the movable ring 62. The movable ring 62 has a hinge portion for hinged at the end of each push-pull rod 6212.

[0051] When the movable ring 62 moves, it drives the push-pull rod 6212 to move. Since the push-pull rod 6212 is hinged to the auxiliary rod 6211, the push-pull rod 6212 pushes the rod 51 when it moves, thereby causing the bar 51 to swing on the fixed ring 61, realizing the distance control between the second X-ray sensor 5 and the X-ray tube assembly body 2.

[0052] See Figures 3-10 As shown, the movable driver 63 is provided with a threaded rod 631, which is coaxially and rotatably mounted on the fixed ring 61. The movable ring 62 is threaded onto the threaded rod 631, and the fixed ring 61 is provided with a second rotary motor 632 for driving the threaded rod 631 to rotate.

[0053] When the active driver 63 is started, the second rotary motor 632 drives the threaded rod 631 to rotate. The threaded rod 631 is threadedly engaged with the movable ring 62, thereby driving the movable ring 62 to move.

[0054] See Figures 3-10 As shown, the upper end of the threaded rod 631 is fixedly fitted with an anti-disengagement ring 6311 to prevent the movable ring 62 from sliding upward and disengaging from the threaded rod 631.

[0055] When the movable ring 62 moves on the threaded rod 631, in order to prevent the movable ring 62 from moving upward and disengaging from the threaded rod 631, the movement range of the movable ring 62 is limited by the anti-disengagement ring 6311 at the end of the threaded rod 631, so that the movement range of the movable ring 62 is between the anti-disengagement ring 6311 and the fixed ring 61.

[0056] See Figures 3-10 As shown, the straight rays passing through the tube opening at the working end of the X-ray tube assembly 2 are directed toward and sensed by the first X-ray sensor 4.

[0057] When the X-ray tube assembly 2 emits a straight ray from the tube, in order to ensure that the first X-ray sensor 4 can accurately detect the straight ray, the X-ray tube assembly 2 and the first X-ray sensor 4 are set on the same plane. This ensures that the straight ray inside the tube irradiates the first X-ray sensor 4, thereby detecting whether the straight ray inside the tube of the X-ray tube assembly 2 is accurate.

[0058] See Figures 3-10 As shown, the straight rays passing through the tube opening from the working end of the X-ray tube assembly 2 are directed toward and sensed by the second X-ray sensor 5.

[0059] When the X-ray tube assembly 2 emits leaking X-rays from outside the tube, the leaking X-rays are emitted toward the second X-ray sensor 5. As the X-ray tube assembly 2 rotates, the second X-ray sensor 5 can detect the leaking X-rays emitted in the circumferential direction outside the tube.

[0060] Example 2

[0061] This embodiment provides a method for detecting leakage radiation using a dedicated leakage radiation detection device for X-ray tube assemblies, comprising the following steps:

[0062] S1. Debugging: Adjust the distance between the second X-ray sensor 5 and the X-ray tube assembly body 2. Drive the movable ring 62 to move vertically through the movable driver 63, which will drive the connected connector 621 to move, thereby pushing multiple bars 51 to swing on the fixed ring 61 at the same time, causing the second X-ray sensor 5 on the bar 51 to move closer to or further away from the X-ray tube assembly body 2, until the second X-ray sensor 5 is within the predetermined range for detecting leaked X-rays.

[0063] S2, Start: Start the sliding driver 32. The sliding driver 32 drives the X-ray tube assembly body 2 to revolve around the annular track 3 while the X-ray tube assembly body 2 maintains its own rotation.

[0064] S3. Detection: The straight rays emitted from the X-ray tube assembly body 2 are received by a number of first X-ray sensors 4 distributed in a circular array along the circumference of the ring 41; the leaking rays emitted outward through the tube wall from the X-ray tube assembly body 2 are received by a number of second X-ray sensors 5 distributed in a straight array at the center of the ring 41.

[0065] The present invention improves the detection effect by moving and rotating the X-ray tube assembly body 2 along the annular track 3, so that the straight rays emitted from the tube and the straight rays emitted from the outside of the tube can be detected by the first X-ray sensor 4 and the second X-ray sensor 5 respectively.

[0066] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
