Description

Technical Field

[0001] This utility model belongs to the field of measurement technology, specifically, it relates to an improvement of the adjustment mechanism for a flat panel detector. Background Technology

[0002] Industrial CT, or computed tomography, is a detection technology applied in industrial fields. This technology can accurately acquire information about the internal and external structure of an object without damaging it, utilizing the penetrating power of X-rays. Through complex reconstruction algorithms, this information is displayed as a three-dimensional image. It has functions such as non-destructive testing, dimensional measurement, and material analysis, and is widely used in the automotive, electronics, and aerospace industries.

[0003] To ensure the quality of the reconstructed 3D images, industrial CT requires system geometric correction. Inaccurate system geometric parameters can lead to image artifacts, thus affecting the detection results. Geometric correction of industrial CT systems is performed using a dedicated standard. After acquiring image data from the standard, the system uses specialized calibration software to calculate and analyze the geometric positional deviations of the three components constituting the industrial CT: the X-ray source, the stage, and the flat panel detector. Based on these deviations, the mechanical positions of these three components are adjusted to correct the system's geometric deviations.

[0004] Existing methods for adjusting the mechanical position of detectors generally employ simple lateral and longitudinal movement mechanisms, which limit the adjustment range and cannot meet the requirements for position correction.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] This invention addresses the aforementioned technical problems existing in the mechanical position adjustment mechanisms of flat panel detectors in the prior art by proposing an adjustment mechanism for flat panel detectors. This mechanism can not only adjust the pitch and yaw angles of the flat panel detector, but also adjust its rotation angle and lateral position, providing more comprehensive position adjustment and meeting the geometric deviation correction requirements of industrial CT systems.

[0007] To achieve the above-mentioned utility model / design objectives, the present utility model adopts the following technical solution: In some embodiments of this application, an adjustment mechanism for a flat panel detector is proposed, comprising a first component, a second component, a third component, and a fourth component connected sequentially from front to back.

[0008] The first component is a first base plate, the second component is a second base plate, the third component is a third base plate, and the fourth component is a fourth base plate. The fourth component is connected and fixed to a vertically arranged support column.

[0009] The first component has a mounting position for mounting the flat panel detector. The flat panel detector is assembled at the mounting position. When fixed, the flat panel detector can be connected and fixed to the first component by screws.

[0010] The pitch and yaw adjustment assembly includes multiple pitch and yaw components for adjusting the pitch and yaw angles of a first component. The multiple pitch and yaw components are arranged circumferentially along the first component, and each pitch and yaw component is connected between the first component and the second component.

[0011] The pitch and yaw adjustment assembly connected between the first component and the second component can adjust the pitch and yaw angles of the first component. Since the flat panel detector is mounted on the first component, the pitch and yaw angles of the flat panel detector can be adjusted.

[0012] In some embodiments of this application, the pitch angle adjustment refers to the adjustment of the rotation angle of the first component along the X-axis direction passing through its horizontal position as the rotation axis; The yaw angle adjustment refers to the adjustment of the rotation angle with the Y-axis direction on the first component as the rotation axis.

[0013] A rotation adjustment assembly, connected between the second and third components, is used to adjust the rotation angle of the second component.

[0014] By using a rotation adjustment assembly connected to the second and third components, the second component can rotate relative to the third component in the horizontal plane, thereby adjusting the rotation angle of the second component. The second component is connected to the first component, which is equipped with a flat panel detector. When the rotation angle of the second component is adjusted, the rotation angle of the flat panel detector is also adjusted.

[0015] A lateral adjustment assembly, connected to the third and fourth components, is used to adjust the lateral position of the third component.

[0016] Because the third component is connected to the second component, when the lateral position of the third component changes relative to the fourth component, the lateral position of the flat panel detector connected to the first component is also adjusted accordingly.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are: The adjustment mechanism for the flat panel detector proposed in this utility model comprises a first component, a second component, a third component, and a fourth component connected in sequence. The flat panel detector is mounted on the first component. A pitch and yaw adjustment component is provided between the first and second components to adjust the pitch and yaw angles of the flat panel detector. A rotation adjustment component is provided between the second and third components to adjust the rotation angle of the flat panel detector. A lateral adjustment component is provided between the third and fourth components to adjust the lateral position of the flat panel detector. Through the cooperation of the pitch and yaw adjustment component, the rotation adjustment component, and the lateral adjustment component, a more comprehensive adjustment of the position of the flat panel detector is achieved, enabling it to meet the geometric deviation correction requirements of industrial CT systems.

[0026] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In some embodiments of this application, an adjustment mechanism for a flat panel detector 700 is proposed, comprising a first component 110, a second component 120, a third component 130, and a fourth component 140 connected sequentially from front to back.

[0028] The first component 110 is the first base plate, the second component 120 is the second base plate, the third component 130 is the third base plate, and the fourth component 140 is the fourth base plate. The fourth component 140 is connected and fixed to a vertically arranged support column 150.

[0029] A mounting position for mounting the flat panel detector 700 is provided on the first component 110. The flat panel detector 700 is assembled at the mounting position. When fixed, the flat panel detector 700 can be connected and fixed to the first component 110 by screws.

[0030] The pitch and yaw adjustment assembly includes multiple pitch and yaw components 200 for adjusting the pitch angle and yaw angle of the first component 110. The multiple pitch and yaw components 200 are arranged circumferentially along the first component 110, and each pitch and yaw component 200 is connected between the first component 110 and the second component 120.

[0031] The pitch and yaw adjustment assembly connected between the first component 110 and the second component 120 can adjust the pitch and yaw angles of the first component 110. Since the flat panel detector 700 is mounted on the first component 110, the pitch and yaw angles of the flat panel detector 700 can be adjusted.

[0032] In some embodiments of this application, the pitch angle adjustment refers to the adjustment of the rotation angle of the first component 110 along the X-axis direction passing through its horizontal position as the rotation axis; The yaw angle adjustment refers to the adjustment of the rotation angle with the Y-axis direction on the first component 110 as the rotation axis.

[0033] A rotation adjustment component 300 is connected between the second component 120 and the third component 130 and is used to adjust the rotation angle of the second component 120.

[0034] By using the rotation adjustment assembly connected to the second component 120 and the third component 130, the second component 120 can rotate relative to the third component 130 in the horizontal plane to adjust the rotation angle of the second component 120. The second component 120 is connected to the first component 110, and the first component 110 is equipped with a flat panel detector 700. When the rotation angle of the second component 120 is adjusted, the rotation angle of the flat panel detector 700 is also adjusted.

[0035] A lateral adjustment component 400 is connected to the third component 130 and the fourth component 140 and is used to adjust the lateral position of the third component 130.

[0036] Since the third component 130 is connected to the second component 120, when the lateral position of the third component 130 relative to the fourth component 140 changes, the lateral position of the flat panel detector 700 connected to the first component 110 is also adjusted accordingly.

[0037] The adjustment mechanism for the flat panel detector 700 proposed in this utility model comprises a first component 110, a second component 120, a third component 130, and a fourth component 140 connected in sequence. The flat panel detector 700 is mounted on the first component 110. A pitch and yaw adjustment assembly is provided between the first component 110 and the second component 120 to adjust the pitch and yaw angles of the flat panel detector 700. A rotation adjustment assembly 300 is provided between the second component 120 and the third component to adjust the rotation angle of the flat panel detector 700. A lateral adjustment assembly 400 is provided between the third component 130 and the fourth component 140 to adjust the lateral position of the flat panel detector 700. Through the cooperation of the pitch and yaw adjustment assembly, the rotation adjustment assembly 300, and the lateral adjustment assembly 400, a more comprehensive adjustment of the position of the flat panel detector 700 is achieved, enabling it to meet the geometric deviation correction requirements of industrial CT systems.

[0038] In some embodiments of this application, the pitch yaw component 200 includes: The adjusting component 210 is screwed into the first component 110, and its end extends out of the first component 110 and extends toward the second component 120; The locking component 220 is screwed into the second component 120 through the adjusting component 210.

[0039] The adjusting component 210 is an adjusting bolt with external threads on its outer surface. The adjusting bolt is hollow inside and is used to pass through the locking component 220.

[0040] A first threaded hole is provided on the first component 110, and the adjusting bolt is threadedly engaged with the threaded hole through the external thread on its outer side.

[0041] The second component 120 is provided with a second threaded hole locking component 220, which is a locking screw that passes through the rear end of the adjusting component 210 and is locked and fixed in the second threaded hole.

[0042] A spherical washer 230, through which the locking component 220 passes, is provided between the locking component 220 and the adjusting component 210, and between the end of the adjusting component 210 and the second component 120.

[0043] When the first component 110 is not adjusted, the end of the locking screw abuts against the spherical washer 230 between itself and the adjusting component 210, and the other end of the adjusting component 210 abuts against another spherical washer 230.

[0044] When the locking component 220 is locked into the second component 120, it will transmit force to the spherical washer 230 located between it and the adjusting component 210, and press the adjusting component 210 tightly through the spherical washer 230. At this time, the adjusting component 210 cannot be rotated for adjustment.

[0045] When adjustment of the first component 110 is required, the locking component 220 can be loosened, and then the adjusting component 210 can be rotated. Since the adjusting component 210 is threadedly engaged with the first component 110, and multiple pitch and yaw components 200 are provided and arranged circumferentially on the first component 110 and the second component 120, when adjusting the adjusting component 210 at one of the positions, the first component 110 cannot rotate due to the limitation of the pitch and yaw components 200 at the other positions, and can only move linearly. When the first component 110 moves linearly, the distance between the first component 110 and the second component 120 at the position of the pitch and yaw component 200 can be adjusted.

[0046] When it is necessary to adjust the pitch or yaw angle of the first component 110, it is necessary to adjust it in conjunction with multiple pitch and yaw components 200 to achieve the desired effect.

[0047] In some embodiments of this application, the first component 110 includes: two opposing first sides 111 and two second sides 112 disposed perpendicular to the first sides 111.

[0048] The pitch and yaw components 200 are provided in three units, which are respectively arranged at one first side 111 and two second side 112 or at one second side 112 and two first side 111.

[0049] Let the first side 111 be a horizontally arranged side, and the second side 112 be a vertical side.

[0050] To facilitate the explanation of the pitch and yaw angles of the pitch and yaw component 200, we will take as an example that one pitch and yaw component 200 is provided on the first side 111 and one pitch and yaw component 200 is provided on each of the two second sides 112.

[0051] When the pitch angle of the first component 110 needs to be adjusted, the pitch tilt component 200 at the first side 111 is adjusted to increase the distance between the two plates at this position by a certain distance. Then, the two pitch tilt components 200 at the second side 112 reduce the distance between the two plates by the same distance as the first side 111. Then the first component 110 will flip downward with the horizontal center line between the two first sides 111 as the center, and vice versa, to achieve the adjustment of the pitch angle of the flat panel detector 700.

[0052] When it is necessary to adjust the tilt angle of the first component 110, the pitch tilt component 200 at the first side 111 is different. Adjusting the distance between the two plates at the position of the pitch tilt component 200 at one of the second sides 112 increases the distance by a certain amount. Adjusting the distance between the two plates at the position of the pitch tilt component 200 at the other second side 112 decreases the moving distance. Decreasing the distance and increasing the distance are the same. Then the first component 110 will flip left and right around the vertical center line between the two second sides 112, thereby adjusting the tilt angle of the flat panel detector 700.

[0053] A locking nut 240 is used to lock the adjusting component 210 and the first component 110 after the adjusting component 210 is adjusted to the correct position. After the adjusting component 210 is screwed into place, the locking nut 240 is tightened against the first component 110 to lock and fix the position of the first component 110.

[0054] When the adjusting component 210 rotates, it moves the first component 110. The first component 110 tilts as it moves. Since the adjusting component 210 is located on the first component 110, it also tilts. The spherical washers 230 provided at both ends of the adjusting component 210 can be used to compensate for the tilt deviation of the adjusting component 210 and ensure that the load is evenly distributed.

[0055] In some embodiments of this application, the adjustment mechanism includes: Support limiting components 500 are provided in at least one set and arranged at the bottom of the first component 110 and the second component 120.

[0056] After the first component 110 is adjusted into place, a vertical upward support force is provided to the first component 110 to ensure the stability of the first component 110 and the flat panel detector 700.

[0057] During setup, two sets of support limiting components 500 can be provided, respectively arranged at the two ends of the first component 110 and the second component 120.

[0058] The support limit component 500 includes: The support base 510 is fixedly connected to the second component 120; The support abutment 520 is screwed into the support base 510, and its end abuts against the bottom of the first component 110; The support locking member 530 is used to lock against the bottom of the support base 510 after the support abutment member 520 is screwed into place.

[0059] The support abutment 520 is a support abutment screw, which is screwed into the support seat 510. It can move up or down relative to the support seat 510 by rotating relative to the support seat 510, so as to match and abut against the first component 110.

[0060] The support locking member 530 is a support locking nut 240, which is used to lock against the bottom position of the first member 110 after the support abutment member 520 has moved into place.

[0061] In some embodiments of this application, the rotation adjustment assembly 300 may be provided in two sets, symmetrically arranged on both sides of the second component 120, and each set of rotation adjustment assemblies 300 includes: The rotating adjustment member 310 is screwed into the third member 130 and its end abuts against the side of the second member 120.

[0062] In some embodiments of this application, a screwing operation portion 131 is formed on the third component 130, and an internal threaded hole is provided in the screwing operation portion 131. An abutment protrusion 121 is formed on the second component 120; The adjusting member is screwed into the internal threaded hole, and its end extends out of the internal threaded hole and abuts against the abutment protrusion 121.

[0063] The screwing operation part 131 is a screwing operation block, and the screwing adjustment part is threadedly engaged with the internal threaded hole.

[0064] The movable limiting member 320 is connected to the second member 120 and the third member 130, and is used to limit the second member 120 to rotate around the movable limiting member 320 when the rotation adjustment member 310 rotates to drive the second member 120 to move.

[0065] In the arrangement, the movable limiting member 320 is positioned at the corner of the second member 120 and the third member 130 opposite to the position of the rotation adjustment assembly 300.

[0066] When it is necessary to adjust the rotation angle of the second component 120, the screw adjustment component can be rotated. The end of the screw adjustment component abuts against the abutment protrusion 121, which will push the second component 120 to move. However, due to the limitation of the movement limit component 320, the second component 120 can only rotate around the movement limit component 320, thereby realizing the adjustment of the rotation angle of the second component 120.

[0067] The locking positioning component 330 is screwed onto the rotary adjusting component 310 to lock the rotary adjusting component 310 after it has been rotated into place.

[0068] The locking and positioning component 330 is a locking and positioning nut. After the adjusting component is screwed into place, the rotating adjusting component 310 is locked.

[0069] In some embodiments of this application, a first through hole 122 is provided on the second component 120, and a second through hole 132 is provided on the third component 130; The movable limiting component 320 includes: a movable limiting screw 321 and a movable locking nut 322; The movable limiting screw 321 includes a head and a rod body. The outer diameter of the head is larger than that of the rod body. The outer diameter of the rod body is the same as the inner diameter of the first through hole 122 and the inner diameter of the second through hole 132. The movable limiting thread passes through the first through hole 122 and the second through hole 132. The movable locking nut 322 is locked to the end of the movable limiting screw 321.

[0070] When it is necessary to adjust the rotation angle of the second component 120, the movable locking nut 322 can be loosened. At this time, the second component 120 can rotate along the movable limit screw 321 when it is under force. After the adjustment is in place, the movable locking nut 322 can be tightened.

[0071] In some embodiments of this application, the adjustment mechanism includes a positioning component 600 connected to the second component 120 and the third component 130, used to press and fix the second component 120 and the third component 130 together after the second component 120 has been rotated into position relative to the third component 130.

[0072] In some embodiments of this application, the positioning component 600 includes a plurality of positioning parts 610, which are arranged circumferentially along the second member 120, and the positioning parts 610 are positioning screws.

[0073] A third through hole 123 is provided on the second component 120, the inner diameter of the third through hole 123 is larger than the outer diameter of the positioning component 610, and a threaded locking hole 133 is provided on the third component 130. The positioning component 610 passes through the third through hole 123 and is locked and fixed in the locking threaded hole.

[0074] When it is necessary to adjust the rotation angle of the second component 120, the positioning component 610 can be loosened to ensure that it does not press and position the second component 120, thus ensuring that the second component 120 rotates normally.

[0075] Furthermore, since the inner diameter of the third through hole 122 is larger than the outer diameter of the positioning component 610, it can be ensured that the second component 120 will not interfere with the second component 120 when it rotates and swings within a certain range.

[0076] In some embodiments of this application, the third component 130 includes: The third component 130 body and the connector 135 connected to the third component 130 body, the connector 135 being connected to the second component 120.

[0077] The third component 130 is a third body plate, and the connector 135 is a connecting rib connected to the third body plate. One end of the connecting rib is connected to the second component 120, and the other end is connected to the third component 130.

[0078] The lateral adjustment assembly 400 includes: a lateral adjustment screw 410, which is rotatably mounted on the fourth component 140 and is threadedly engaged with the connector 135; A limiting component is disposed between the fourth component 140 and the third component 130 to limit the linear movement of the connector 135 and the fourth component 140.

[0079] A mounting base 141 is provided on the fourth component 140, and a slot 142 is provided on the top of the mounting base 141.

[0080] A limiting nut 420 is provided on the transverse adjusting screw 410. When the transverse adjusting screw 410 is locked in the bayonet 142, the limiting nut 420 is located at one end of the bayonet 142. The limiting nut 420 and the head of the transverse adjusting screw 410 cooperate to limit the movement of the transverse screw, so that the transverse adjusting screw 410 can only rotate within the mounting base 141.

[0081] A threaded hole is provided in the connector 135, and the lateral adjusting screw 410 is screwed into it.

[0082] The limiting component includes a limiting elongated hole 136 disposed on the third component 130 and a limiting post 143 disposed on the fourth component 140, with the limiting post 143 inserted into the limiting elongated hole 136.

[0083] When the lateral adjustment screw 410 rotates, it will drive the connector 135 and the third component 130 to move linearly relative to the fourth component 140, thereby realizing the lateral position adjustment of the third component 130 and the second component 120, the first component 110 and the flat panel detector 700 connected to it.

[0084] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
