[0031] In the following, exemplary embodiments of the present application will be described with reference to the drawings. In the description, not all features of a practical implementation are described in order to be clear and concise. It should be appreciated, however, that many implementation-specific decisions can have to be made in order to develop any such practical implementation, to implement developer-specific goals, such as compliance with system- and business-related constraints, which will vary from one implementation to another. Moreover, it should be appreciated that a development effort, to develop a practical implementation, can be complex and time-consuming, but can nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0032] It should also be noted that, in the description, only the device structures and / or processing steps closely related to the scheme according to the present application are shown in the drawings, and other details not closely related to the present application are omitted, in order to avoid obscuring the present application with unnecessary details.

[0033] In the related art, when testing with an X-ray machine, multiple radiation qualities can need to be replaced. In order to avoid a large radiation dose from manual operation, a wheel disc type filtering device is usually used to automatically replace the radiation quality. The wheel disc type filtering device includes a rotatable wheel disc, multiple radiation qualities arranged at intervals along the circumferential direction of the wheel disc, a driving piece for driving the wheel disc to rotate by a certain angle, and a control piece for controlling the rotation angle of the wheel disc. In operation, the rotation angle of the wheel disc is controlled by inputting an angle or a radiation quality number in the control piece, so as to select a target radiation quality to be aligned with the beam outlet of the X-ray machine.

[0034] The number of radiation qualities in the wheel disc type filtering device is restricted by the radius of the wheel disc. If more radiation qualities are needed to be installed on the wheel disc, a wheel disc with a larger size is needed. When installing, the maximum size of the wheel disc is restricted by the site environment, and the number of radiation qualities is also restricted. In addition, the wheel disc with a too large size will cause other structures such as the shielding body of the X-ray machine to be large, and will also affect the installation of other structures such as the diaphragm. Moreover, the inventors of the present application find that due to the large beam energy of the beam exit of the X-ray machine, the wheel disc with a large size may cause large scattering before the beam exit, which will increase the background level of the laboratory and affect the accuracy of the test.

[0035] In view of the above problems, the embodiments of the present application provide a radiation quality switching device suitable for an X-ray machine.

[0036] Referring to Figure 1 and Figure 2 which show a schematic diagram of filtering the X-rays emitted by the X-ray machine by using the radiation quality switching device provided by the embodiments of the present application, Figure 1 in which the target radiation quality is in a waiting position, Figure 2 in which the target radiation quality is located at a position aligned with the beam exit of the X-ray machine.

[0037] The radiation quality switching device 100 suitable for the X-ray machine provided by the embodiments of the present application can include a platform 10, a holding moving assembly 20 and a grabbing moving assembly 30. The X-ray machine 300 is arranged on the platform 10; the holding moving assembly 20 is arranged on the platform 10 and is used for holding a plurality of radiation qualities 200 and is arranged to be able to drive the plurality of radiation qualities 200 to move relative to the platform 10 to move the target radiation quality to the waiting position; and the grabbing moving assembly 30 is used for grabbing the target radiation quality 200 in the waiting position and moving the target radiation quality 200 to a position aligned with the beam exit 301 of the X-ray machine 300.

[0038] The radiation quality switching device 100 provided by the embodiments of the present application can hold a large number of radiation qualities 200 by using the holding moving assembly 20, and move the target radiation quality 200 to be replaced to the waiting position; and can grab the target radiation quality 200 in the waiting position by using the grabbing moving assembly 30, and move the target radiation quality 200 to the position aligned with the beam exit 301 of the X-ray machine 300, which is beneficial to reduce the space occupied by the structural members near the beam exit 301, thereby being beneficial to reduce the scattering of X-rays near the beam exit 301 caused by the radiation quality switching device 100 and to reduce the background level.

[0039] In some embodiments, the X-ray machine 300 comprises an X-ray machine body and a shielding member 302, the X-ray machine body is disposed in the shielding member 302, the beam outlet 301 is formed in the shielding member 302, the X-ray machine body is used to emit an X-ray beam, and the X-ray beam emitted by the X-ray machine body can pass through the beam outlet 301 to the outside of the shielding member 302. The shielding member 302 is made of, for example, aluminum.

[0040] In some embodiments, the platform 10 can be made of aluminum.

[0041] Referring to Figure 1 and Figure 2 In some embodiments, the grabbing moving assembly 30 can comprise a grabbing member 31, a first moving member 32, and a first driving member 33. The grabbing member 31 is used to grab the target radiation quality 200; the first moving member 32 is arranged to be capable of driving the grabbing member 31 to move relative to the platform 10 to a position such that the grabbing member 31 can grab the target radiation quality 200 in the waiting position; or to a position such that the target radiation quality 200 grabbed by the grabbing member 31 is aligned with the beam outlet 301 of the X-ray machine 300. The first driving member 33 is arranged to drive the first moving member 32 to move relative to the platform 10. In such embodiments, the grabbing member 31 can be arranged at the beam outlet 301 of the X-ray machine 300, thereby greatly reducing the space occupied by structural members near the beam outlet 301, thereby facilitating the reduction of X-ray scattering near the beam outlet 301 caused by the radiation quality switching device 100, and reducing the background level.

[0042] In some embodiments, the first driving member 33 is, for example, a stepping motor or a pneumatic cylinder.

[0043] In some embodiments, the holding moving assembly 20 can be arranged on one side of the front of the X-ray machine 300, thereby avoiding the scattering of X-rays by the holding moving assembly 20 as much as possible.

[0044] Referring to Figures 3 to 5 , Figures 3 to 5 respectively from different angles Figure 1 The schematic diagram of the radiation quality switching device and the X-ray machine is shown. In some embodiments, the holding moving assembly 20 can comprise a holding member 21, a second moving member 22, and a second driving member 23. The holding member 21 is used to hold a plurality of radiation qualities 200; the second moving member 22 is arranged to be capable of driving the holding member 21 to move relative to the platform 10; and the second driving member 23 is arranged to drive the second moving member 22 to move relative to the platform 10, so as to move the target radiation quality 200 to the waiting position capable of being grabbed by the grabbing member 31. In such embodiments, the first moving member 32 is driven by the second driving member 23 to move, so as to move the holding member 21 to the waiting position such that the target radiation quality 200 can be grabbed by the grabbing member 31, thereby facilitating the grabbing member 31 to grab the target radiation quality 200.

[0045] Referring to Figures 1 to 5 In some embodiments, the radiation quality 200 can include a radiation quality body 201, a frame 202 for fixing the radiation quality body 201, and an operation part 203 connected with the frame 202, the dimension of the operation part 203 along the thickness direction of the radiation quality body 201 is smaller than the dimension of the frame 202 along the thickness direction of the radiation quality body 201. The holder 21 forms a plurality of holding grooves 210, the dimension of the holding groove 210 along the thickness direction of the radiation quality body 201 is greater than the dimension of the operation part 203 along the thickness direction of the radiation quality body 201, and smaller than the dimension of the frame 202 along the thickness direction of the radiation quality body 201, the operation part 203 can pass through one holding groove 210 downwardly so that the frame 202 can be hung on the holder 21. In such embodiments, the holder 21 is equivalent to a comb shape, and the radiation quality 200 is hung between two adjacent comb teeth. In this way, the structure of the holder 21 is simple, and the number of the radiation qualities 200 held by the holder 21 can be increased only by increasing the number of the holding grooves 210 of the holder 21.

[0046] In some embodiments, the grabbing part 31 is used to grab the operation part 203 of the target radiation quality 200 below the holder 21. The first moving part 32 is arranged to be movable along the extension direction of the holding groove 210, so as to move the radiation quality body 201 of the target radiation quality 200 to a position aligned with the beam outlet 301 of the X-ray machine 300. In such embodiments, since the operation part 203 can pass through one holding groove 210 downwardly so that the frame 202 can be hung on the holder 21, the operation part 203 of the target radiation quality 200 is grabbed by the grabbing part 31, and then the grabbing part 31 is moved by the first moving part 32, so that the target radiation quality 200 can be transferred from the holder 21 to the grabbing part 31, and moved to a position aligned with the beam outlet 301 of the X-ray machine 300. In this way, only the grabbing part 31 and the target radiation quality 200 are located near the beam outlet 301, further reducing the scattering of X-rays near the beam outlet 301 caused by the radiation quality switching device 100, and reducing the background level.

[0047] In addition, when the radiation quality 200 is replaced, the first moving part 32 only needs to move the grabbing part 31 in the opposite direction to a position where the radiation quality 200 currently grabbed by the grabbing part 31 is in the standby position, and then the grabbing part 31 is released, so that the radiation quality 200 can be hung on the holding groove 210. As can be seen, in such embodiments, the first moving part 32 of the grabbing and moving assembly 30 only has one degree of freedom, which simplifies the structure of the grabbing and moving assembly 30, and also makes the transfer operation of the radiation quality 200 very simple.

[0048] The radiation quality body 201 can be circular. It is easily understood that when the radiation quality body 201 of the target radiation quality 200 is aligned with the beam outlet 301 of the X-ray machine 300, the radiation quality body 201 of the target radiation quality 200 is coaxial with the beam outlet 301 of the X-ray machine 300.

[0049] In some embodiments, the radiation quality body 201 can be made of lead, tin, aluminum or copper, for example. The radiation quality body 201 of different materials and different thicknesses has different filtering effects on X-rays, and different specifications of the radiation quality 200 can be selected according to different filtering needs.

[0050] It is easily understood that although the thicknesses of the radiation quality bodies 201 of the plurality of radiation qualities 200 are not completely the same, the sizes of the operation portions 203 of the radiation qualities 200 are completely the same. In this way, it is beneficial to simplify the structure of the grabbing member 31 and the operation.

[0051] In some embodiments, the holding member 21 can be made of brass. Since the brass is smooth in texture, in such embodiments, the holding member 21 made of brass facilitates the synchronous movement of the radiation quality 200 with the grabbing member 31 to leave or return to the holding groove 210.

[0052] In some embodiments, the platform 10 is provided with a rack 101 extending along the axial direction of the beam outlet 301 of the X-ray machine 300, and the second moving member 22 is provided with a gear 222 engaged with the rack 101, and through the engagement of the gear 222 and the rack 101, the second moving member 22 can move relative to the platform 10.

[0053] In some embodiments, the second moving member 22 is provided with a rack 101 extending along the axial direction of the beam outlet 301 of the X-ray machine 300, and the platform 10 is provided with a gear 222 engaged with the rack 101, and through the engagement of the gear 222 and the rack 101, the second moving member 22 can move relative to the platform 10.

[0054] In some embodiments, the second moving member 22 can include a moving body 221, and the holding member 21 and the rack 101 are both arranged on the moving body 221, and through the engagement of the gear 222 and the rack 101, the moving body 221 can move relative to the platform 10, thereby driving the holding member 21 to move relative to the platform 10.

[0055] In some embodiments, the moving body 221 can include a first plate 2211 and a second plate 2212 fixedly connected, the holder 21 and the rack 101 are arranged on the first plate 2211, the first plate 2211 is arranged perpendicularly to the holder 21, and the second plate 2212 is arranged parallel to the holder 21. Through the meshing action of the gear 222 and the rack 101, the first plate 2211 can move relative to the platform 10, thereby driving the second plate 2212 and the holder 21 to move relative to the platform 10.

[0056] In some embodiments, the first plate 2211 and the holder 21 can be connected by using a right-angle connecting block.

[0057] The first plate 2211 and the second plate 2212 are made of, for example, carbon steel.

[0058] In some embodiments, the second driving member 23 is, for example, a stepper motor.

[0059] Referring to Figure 1 and Figure 3 In some embodiments, the radiation quality switching device 100 can further include a mounting portion 40 arranged below the platform 10, the mounting portion 40 being provided with a sliding fitting portion 401. The first moving member 32 includes a body 321 and a sliding portion 322 connected to the body 321, the sliding portion 322 being in sliding fitting with the sliding fitting portion 401. The platform 10 forms a sliding groove 102, the body 321 is connected to the grabbing member 31 by passing through the platform 10 from bottom to top, and when the sliding portion 322 slides relative to the sliding fitting portion 401, the body 321 slides in the sliding groove 102. In such embodiments, the body 321 slides in the sliding groove 102 to drive the grabbing member 31 and the target radiation quality 200 grabbed by the grabbing member 31 to move to a position aligned with the beam outlet 301 of the X-ray machine 300. Since the mounting portion 40 is arranged below the platform, the body 321 of the first moving member 32 passes through the platform 10 from bottom to top to be connected to the grabbing member 31, which is beneficial to reduce the part of the first moving member 32 above the platform, and is further beneficial to reduce the scattering of X-rays near the beam outlet 301 caused by the first moving member 32, thereby reducing the background level.

[0060] In some embodiments, the sliding part 322 can be a sliding block, and the sliding fitting part 401 can be a sliding rail. The grabbing moving assembly 30 can further include two limiters 34, which are respectively arranged at two ends of the sliding rail 401, and are used for limiting the sliding block 322, so that the first moving part 32 can drive the target radiation quality 200 to move to a position aligned with the beam outlet 301 of the X-ray machine 300 or a position (i.e. a standby position) hung on the holding part 21. In such embodiments, by limiting the sliding block 322 through the limiters 34, the position of the target radiation quality 200 is facilitated to be positioned, so as to ensure that the target radiation quality 200 can move to the position aligned with the beam outlet 301 of the X-ray machine 300 or the position hung on the holding part 21.

[0061] The limiters 34 are, for example, metal blocks fixed to the mounting part 40, and the two ends of the sliding rail 401 are respectively connected with the two metal blocks.

[0062] In some embodiments, the body 321 can be composed of rod parts, so as to further reduce the scattering of X-rays caused by the first moving part 32 near the beam outlet 301.

[0063] In some embodiments, the body 321 can include a first rod part 3211 connected with the sliding part 322 and extending upward through the sliding groove 102, a second rod part 3212 extending from an upper end of the first rod part 3211 towards a direction close to the holding moving assembly 20, and the second rod part 3212 is connected with the grabbing part 31. In such embodiments, above the platform 10, the structure located in front of the X-ray machine 300 only includes an upper part of the first rod part 3211, the second rod part 3212, the grabbing part 31 and the radiation quality 200, so as to greatly reduce the scattering of X-rays caused by the radiation quality switching device 100 near the beam outlet 301, and facilitate to reduce the background level of the test environment.

[0064] In some embodiments, the operating part 203 is provided with a position monitoring part, and the second driving part 23 drives the second moving part 22 to move to a standby position in which the target radiation quality 200 is aligned with the grabbing part 31 according to monitoring data of the position monitoring part. In such embodiments, the above-mentioned arrangement facilitates to realize the accurate positioning of the target radiation quality 200 and the grabbing part 31, and then facilitates the grabbing part 31 to grab the target radiation quality 200.

[0065] In some embodiments, the position monitoring part is, for example, a limit photoelectric switch or a magnetic grating ruler.

[0066] Referring to Figure 6 , Figure 6is a structural schematic diagram of the grabbing member 31 of an embodiment of the present application. In some embodiments, the grabbing member 31 can form a grabbing groove 310 that is shaped to match the shape of the operation part 203 of the radiation quality 200, and the operation part 203 can enter the grabbing groove 310 to achieve grabbing. Since the grabbing member 31 grabs the operation part 203 instead of the frame 202 of the radiation quality 200, the grabbing member 31 is away from the beam outlet 301 of the X-ray machine 300, and the scattering caused by the grabbing member 31 is reduced.

[0067] The grabbing member 31 is made of, for example, aluminum. To ensure that the target radiation quality 200 will not be separated from the grabbing member 31 when grabbed by the grabbing member 31, an anti-skid layer can be added to the wall surface of the grabbing groove 310. In some embodiments, the anti-skid layer can be formed of rubber.

[0068] In some embodiments, the grabbing member 31 can include two grabbing elements 311 that are oppositely arranged, and the surfaces of the two grabbing elements 311 that face each other form half grooves that are shaped to match the shape of the operation part 203, and the half grooves formed by the two grabbing elements 311 together form the grabbing groove 310.

[0069] In some embodiments, the shape of the grabbing member 31 can be determined according to actual grabbing needs. In some embodiments, the grabbing stroke of the grabbing member 31 is greater than the diameter of the operation part 203.

[0070] In some embodiments, the radiation quality switching device 100 can further include a grabbing driving member for driving the grabbing member 31 to grab the target radiation quality 200. The grabbing driving member is, for example, an electromagnet or a pneumatic device.

[0071] The radiation quality switching device 100 provided by the embodiments of the present application can reduce the participation of the operator, reduce the radiation dose received by the operator, improve the switching efficiency of the radiation quality 200, reduce the scattering of X-rays caused by the setting of the radiation quality switching device 100, reduce the background level, and improve the test accuracy.

[0072] In addition, the radiation quality switching device 100 provided by the embodiments of the present application has a compact structure, is convenient to integrate and install on site.

[0073] In some embodiments, the radiation quality switching device 100 provided by the embodiments of the present application can be arranged in an X-ray machine standard measurement laboratory.
