[0034] The specific embodiments of the present invention will be described in detail below. It should be noted that the embodiments described herein are only for illustration and are not intended to limit the present invention.

[0037] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0038] The embodiment of the present invention provides a detection device. Before introducing the technical solution provided by the embodiment of the present invention, the related technologies involved in the present invention are first described.

[0039] In the related technology, in the field of industrial inspection, digital X-ray inspection refers to the use of X-rays to scan the workpiece and form an image on the imaging plate to determine whether there are defects inside the workpiece through the image. This technology can obtain information such as the internal structure and density of the object without destroying the object.

[0040] Digital radiography is divided into DR (Digital Radiology) and CT (Computed Tomography). The X-rays generated by the ray source (for example, an accelerator or an X-ray machine) form a fan-shaped X-ray beam under the limitation of the mechanical system. The X-ray beam attenuates after penetrating the workpiece to be inspected, and different degrees of attenuation reflect the internal information of the workpiece to be inspected. The detector and reconstruction inspection system receive the attenuated X-ray beam and convert it into a digital signal to generate an image. DR scanning is to obtain the overall projection data by scanning the workpiece to be inspected through the synchronous translation of the ray source and the detector, and then the acquired projection data is processed and reconstructed to obtain the transmission image of the workpiece to be inspected. CT scanning is to obtain the projection data from multiple angles by synchronous translation of the ray source and the detector to the workpiece to determine the position of the workpiece, and then the acquired projection data is processed and reconstructed to obtain the tomographic image of the workpiece to be inspected. However, the digital ray detection equipment of the related technology has the problems of inconvenient control, single function and small scope of application in practical applications, which need to be further improved or perfected.

[0041] In view of this, an embodiment of the present invention provides a detection device, wherein the device includes: a ray source, which is used to at least form rays suitable for scanning and detecting the object to be inspected; a detector group, which is arranged opposite to the ray source, and a detection area is formed between the ray source and the detector group, and the detector group is used to receive the rays passing through the object to be inspected; a base, which is in a circular ring shape, and a part of the base is located between the ray source and the detector group; a rotating table, which is arranged concentrically with the base, the rotating table is rotatably arranged on the base, and the rotation direction is consistent with the circumference arrangement direction of the base; a plurality of trays, all of which are arranged on the rotating table, and the plurality of trays are arranged at intervals along the circumference direction of the base, and each tray is used to place the object to be inspected; and a detection table, which is arranged in the detection area, and the detection table is used to place the object to be inspected and drive the object to be inspected to rotate.

[0042] Figure 1 is a schematic structural diagram of a detection device according to some exemplary embodiments of the present invention.

[0043] Combine the following Figure 1 The detection device according to the embodiment of the present invention is described in detail.

[0044] like Figure 1 As shown, the device includes a ray source 100, a detector group 200, a workbench and a detection table.

[0045] The radiation source 100 is designed in a vertical position, and can generate an X-ray fan beam that penetrates the object under test. The detector group 200 is also designed in a vertical position, and is arranged opposite to the radiation source 100, and a detection area is formed between the radiation source 100 and the detector group 200, and the detector group 200 can receive X-rays that pass through the object under test.

[0046] It should be noted that the ray source 100 may be an X-ray source of different energies; the detector group 200 may be an arc detector, a flat panel detector or a linear detector. According to different detection requirements, different types of detectors may be selected to match the ray source 100.

[0047] The workbench comprises: a base 1 , a rotating table 2 and a plurality of trays 41 .

[0048] The base 1 serves as a base for supporting other components. The base 1 is in a circular ring shape, the radiation source 100 is located on the outside of the base 1, and the detector group 200 is located on the inside of the base. A portion of the base 1 is located between the radiation source 100 and the detector group 200, and a station to be detected located in the detection area is formed in this portion. The base 1 is independently provided with the radiation source 100 and the detector group 200. The turntable 2 is also in a circular ring shape, and the turntable 2 is concentrically provided with the base 1. The turntable 2 is rotatably provided on the base 1, and the rotation direction is consistent with the circumference layout direction of the base 1. A plurality of trays 41 are provided on the turntable 2, and the plurality of trays 41 are arranged at intervals along the circumference direction of the base 1, and each tray 41 is used to place the object to be inspected.

[0049] The detection table 7 is arranged in the detection area. The detection table 7 is arranged inside the base 1 and is located between the base 1 and the detector group 200. The detection table 7 is used to place the object to be detected, and the detection table 7 can drive the object to be detected to rotate.

[0050] It can be understood that the object to be tested on the tray 41 rotates to the inspection station with the rotating turntable 2, and then the ray source 100 generates X-rays, which penetrate the object to be tested and attenuate. The attenuated X-rays are received by the detector group 200 and processed to generate an image. On the one hand, in the device, the object to be tested is placed on the tray 41, and the turntable 2 drives the object to be tested on the tray 41 to rotate to the detection area, automatically completing the automatic switching of multiple objects to be tested. In the detection area, the ray source 100 and the detector group 200 cooperate to achieve DR detection of a certain angle of the object to be tested on the tray 41, and obtain the DR transmission detection image of the object at this angle. On the other hand, the object to be tested is placed on the detection table 7, and the detection table 7 drives the object to be tested to rotate 360° to achieve detection of multiple angles of the object to be tested, and obtain a CT tomographic image of the internal structure of the object to be tested. In this way, multiple detection methods can coexist, and the applicability of the device is improved.

[0051] According to an embodiment of the present invention, the detection device includes a first working mode and a second working mode.

[0052] In the first working mode, the plurality of trays 41 are rotated to the inspection station in sequence under the rotation drive of the turntable 2 to perform the inspection work, so that the inspected object on the tray 41 is stationary in the inspection area. The ray source 100 emits an X-ray fan beam, and the X-ray penetrates the inspected object at the inspection station from a certain angle. The detector group 200 receives the X-ray that penetrates the inspected object, and cooperates with the mechanical system, the control system and the software system to obtain the transmission image of the inspected object at a certain angle, thereby completing the DR scanning inspection.

[0053] In the second working mode, the object placed on the inspection table 7 is located in the inspection area, and the object rotates 360 degrees driven by the inspection table 7. The ray source 100 emits an X-ray fan beam, and as the object on the inspection table 7 continuously rotates, the X-ray penetrates the object at the inspection station from different angles, and the detector group 200 receives the X-ray that penetrates the object, and cooperates with the control system, mechanical system and software system to obtain a tomographic image of the object, thereby completing the CT scanning test.

[0054] It can be understood that the device combines DR detection and CT detection, and the device can be used to perform both DR scanning and CT scanning on the workpiece, thereby improving the diversity and reliability of detection and having the advantage of flexible control.

[0055] Combine the following Figures 2 to 7B The first working mode of the embodiment of the present invention: the working mode of DR detection is described in detail.

[0056] Figure 2 Schematic diagram of the structure of a turntable according to some exemplary embodiments of the present invention. Figure 3 yes Figure 1 Schematic diagram of the cross-sectional structure at AA in the middle. Figure 4 It is a schematic diagram of the structure of the rotational assembly between the turntable and the base of some exemplary embodiments of the present invention.

[0057] like Figure 2 , Figure 3 and Figure 4 As shown, the device further includes a first driving mechanism. The first driving mechanism 3 is used to drive the turntable 2 to rotate along the circumference direction of the base 1, so that the turntable 2 can perform reciprocating rotational motion along the circumference direction of the base 1 with the center of the circle of the base 1 as the center.

[0058] An inner ring 11 is provided on the side of the base 1 close to the turntable 2, and the inner ring 11 is concentrically arranged with the base 1. An outer ring 21 is provided on the side of the turntable 2 away from the supporting tray 41, and the outer ring 21 is concentrically arranged with the base 1. The outer ring 21 is located on the outer peripheral side of the inner ring 11, and the outer ring 21 and the inner ring 11 are slidably engaged with each other, and the sliding direction is consistent with the circumference layout direction of the base 1.

[0059] Specifically, the first driving mechanism 3 drives the outer ring 21 to rotate in a forward or reverse direction, thereby driving the turntable 2 to reciprocate along the circumference of the base 1 .

[0060] Continue to refer to Figure 3 and Figure 4 The first driving mechanism 3 includes: a ring gear 31, a first gear 32 and a driving member 33.

[0061] The gear ring 31 is arranged on the outer peripheral side of the outer ring 21, and the gear ring 31 is arranged concentrically with the turntable 2. The first gear 32 is rotatably arranged on the base 1, and the first gear 32 is meshed with the gear ring 31. The driving member 33 is arranged on one side of the base 1, and the driving member 33 is used to drive the first gear 32 to rotate.

[0062] Exemplarily, the driving member 33 may be a servo motor, which is vertically fixed on the ground, with the output end of the servo motor facing upward, and the output end of the servo motor is coaxially fixedly connected to the first gear 32 .

[0063] In other embodiments, the driving member 33 may also be a stepping motor.

[0064] It is understandable that during DR testing, multiple workpieces to be processed are placed on multiple trays 41 respectively, and the driving member 33 drives the first gear 32 to rotate, thereby driving the gear ring 31 meshing therewith to rotate. Due to the sliding assembly between the outer ring 21 and the inner ring 11, the turntable 2 can rotate along the circumference of the base 1, so that the multiple trays 41 on the turntable 2 are continuously switched to the positions to be tested / processed, so that the multiple workpieces to be processed can be rotated to the positions to be tested / processed in turn, and the automatic switching of multiple objects to be tested can be realized, batch testing can be performed, and work efficiency can be improved. At the same time, multiple trays 41 are convenient for placing different types of objects to be tested, so that different types of objects to be tested can be tested in the same batch, improving the detection efficiency.

[0065] Figure 5 It is a schematic diagram of the layout structure of multiple support trays in the support tray of some exemplary embodiments of the present invention.

[0066] In some exemplary embodiments of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, the workbench also includes 21 support tray groups 4, and the 21 support tray groups 4 are evenly spaced along the circumference direction of the base 1. Each support tray group 4 includes three support trays 41. The three support trays 41 in each support tray group 4 are evenly spaced along a straight line, and the straight line is the tangent of the turntable surface 2 at the support tray group 4.

[0067] It should be noted that the embodiment of the present invention does not specifically limit the number of the tray groups 4 and the trays 41 in each tray group 4. For example, the tray groups 4 can be set to ten, fifteen, twenty or thirty. The number of trays 41 in each tray group 4 can also be set to one, two, four or five. The number of tray groups 4 and the number of trays 41 in each tray group 4 can be adjusted according to the needs of workpiece processing.

[0068] In some embodiments, a baffle is provided around the edge of each tray 41. The three trays 41 of each tray group 4 are respectively the first tray 411, the second tray 412 and the third tray 413, and the second tray 412 is located between the first tray 411 and the third tray 413. The first tray 411 and the third tray 413 are located at a first height, and the second tray 412 is located at a second height, and the first height is lower than the second height in the vertical direction. That is, the first tray 411 and the third tray 413 are located at different heights from the second tray 412 in the vertical direction.

[0069] It is understandable that the multiple trays 41 in each tray group 4 are arranged at different heights so that when the workpieces to be processed are placed on the trays 41 for testing, they will not interfere with each other, which is conducive to improving space utilization.

[0070] In some embodiments, at least two trays 41 in at least one tray set 4 have different diameters. Specifically, the first tray 411 and the third tray 413 have first diameters, respectively, and the first diameters of the first tray 411 and the third tray 413 are the same. The second tray 412 has a second diameter, which is greater than the first diameter.

[0071] It can be understood that the multiple trays 41 in each tray group 4 are set with different diameters to facilitate the placement of workpieces of different sizes to be processed and meet the detection of workpieces of different sizes, thereby improving the applicability of the workbench.

[0072] It should be noted that the embodiment of the present invention does not specifically limit the diameter and layout height of the multiple trays 41 in each tray group 4. For example, the multiple trays 41 in each tray group 4 can be located at the same height or at different heights. The multiple trays 41 in each tray group 4 can have the same diameter or different diameters. The height and diameter of the trays 41 in each tray group 4 can be adjusted according to the requirements of workpiece processing.

[0073] The device further includes a second driving mechanism 5. The tray 41 is rotatably disposed on the turntable 2, and the rotation axis of the tray 41 is perpendicular to the side of the turntable 2 away from the base 1. When each tray group 4 rotates to a processing station, the second driving mechanism 5 is used to drive multiple trays 41 in each tray group 4 to rotate synchronously.

[0074] It is understandable that, under the condition that the tray 41 can rotate along the circumference of the base 1, each tray 41 can rotate at the processing station, and can realize DR detection of different angles of the workpiece to be processed. For DR detection, when multiple tray groups 4 rotate with the turntable 2, batch detection of workpieces can be realized in batches, thereby improving detection efficiency. At the same time, the tray 41 in each tray group 4 can rotate at the processing station, and can realize DR scanning of different angles of the workpiece to be processed. Further improve the convenience of using the device.

[0075] Fig. 6A is a schematic diagram of the connection structure between the support tray and the second driving mechanism of some exemplary embodiments of the present invention; Figure 6B yes Figure 2 Enlarged view of point B in the middle.

[0076] In some exemplary embodiments of the present invention, Figure 3 , 6A As shown in FIGS. 6B and 6B , the second driving mechanism 5 includes a first synchronous wheel 51 , a second synchronous wheel 52 , a third synchronous wheel 53 and a synchronous component 54 .

[0077] The turntable 2 is provided with a plurality of rotating shaft groups, one rotating shaft group corresponds to one bearing tray group 4, and each rotating shaft group has a plurality of rotating shafts, and the number of rotating shafts in each rotating shaft group is consistent with the number of bearing trays 41 in the corresponding bearing tray group 4. Specifically, each rotating shaft group includes a first rotating shaft, a second rotating shaft and a third rotating shaft, and the first rotating shaft, the second rotating shaft and the third rotating shaft are all vertically rotatably arranged on the turntable 2, and both ends of the first rotating shaft, the second rotating shaft and the third rotating shaft are located on both sides of the turntable 2. The first bearing tray 411 is coaxially fixedly connected to the upper end of the first rotating shaft, the second bearing tray 412 is coaxially fixedly connected to the upper end of the second rotating shaft, and the third bearing tray 413 is coaxially fixedly connected to the upper end of the third rotating shaft. The first synchronous wheel 51 is coaxially fixedly connected to the lower end of the first rotating shaft, the second synchronous wheel 52 is coaxially fixedly connected to the lower end of the second rotating shaft, and the third synchronous wheel 53 is coaxially fixedly connected to the lower end of the third rotating shaft. The synchronization component 54 is used to drive the first synchronization wheel 51 , the second synchronization wheel 52 and the third synchronization wheel 53 to rotate synchronously.

[0078] It can be understood that the synchronization component 54 drives the first synchronization wheel 51, the second synchronization wheel 52 and the third synchronization wheel 53 to rotate synchronously, thereby driving the first support tray 411, the second support tray 412 and the third support tray 413 in each support tray group 4 to rotate simultaneously, saving power source.

[0079] In some embodiments, the synchronous component 54 includes: a fourth synchronous wheel 542 , a first transmission belt 541 , a second transmission belt 543 , a friction wheel 544 and a power assembly 545 .

[0080] The fourth synchronous wheel 542 is coaxially fixedly connected to the lower end of the second rotating shaft, and the fourth synchronous wheel 542 is below the second synchronous wheel 52. The first transmission belt 541 is sleeved on the second synchronous wheel 52 and the third synchronous wheel 53; the second transmission belt 543 is sleeved on the first synchronous wheel 51 and the fourth synchronous wheel 542. The friction wheel 544 is coaxially fixedly connected to the lower end of the second rotating shaft, and the friction wheel 544 is below the fourth synchronous wheel 542. The power assembly 545 is used to drive the friction wheel 544 to rotate.

[0081] It can be understood that the power assembly 545 drives the friction wheel 544 to rotate, driving the second synchronous wheel 52 and the fourth synchronous wheel 542 to rotate, the second synchronous wheel 52 drives the third synchronous wheel 53 to rotate through the first transmission belt 541, and the fourth synchronous wheel 542 drives the first synchronous wheel 51 to rotate through the second transmission belt 543, thereby realizing the simultaneous rotation of the first bearing tray 411, the second bearing tray 412 and the third bearing tray 413 on the first rotating shaft, the second rotating shaft and the third rotating shaft. When the workpiece to be processed on the bearing tray 41 rotates to the station to be detected, the DR scanning of the workpiece to be processed at different angles is realized by rotating the rotating disk.

[0082] In other embodiments, the first synchronous wheel 51, the second synchronous wheel 52, the third synchronous wheel 53 and the fourth synchronous wheel 542 can all be replaced with gears. At the same time, the first transmission belt 541 and the second transmission belt 543 can be replaced with chains meshing with the gears, thereby realizing the synchronous rotation of the first rotating shaft, the second rotating shaft and the third rotating shaft.

[0083] In some embodiments, the power assembly 545 includes: a friction roller 5451a.

[0084] The device also includes a turntable 91. The turntable 91 is slidably arranged on one side of the base 1, and the sliding direction of the turntable 91 is consistent with the radial layout direction of the base 1. The friction roller 5451a is vertically rotatably arranged on the turntable 91 (because the friction roller 5451a and the turntable of the detection table 7 share a common driving method, the rotation method of the friction roller 5451a will be described when introducing the CT detection). When the tray group 4 rotates to the processing station, the turntable 91 slides to make the friction roller 5451a rotate and contact with the friction wheel 544, and the friction roller 5451a rotates, thereby driving the friction wheel 544 in contact with the friction roller 5451a to rotate synchronously; when the tray group 4 does not need to rotate, the turntable 91 slides to make the friction roller 5451a away from the friction wheel 544.

[0085] Furthermore, the workbench further comprises a linear drive and a slide rail, the slide rail is arranged on the ground, a slide groove is provided on the turntable 91, and the slide rail and the slide groove are slidably assembled. The linear drive is arranged on the ground, and the output end of the linear drive is fixedly connected to the workbench.

[0086] Exemplarily, the linear drive member may be a cylinder, and an output end of the cylinder is fixedly connected to the turntable 91 .

[0087] It is understandable that when the tray 41 that needs to be rotated to the inspection station rotates, the linear drive member drives the turntable 91 to slide, so that the friction roller 5451a gradually approaches the friction wheel 544 until the friction roller 5451a contacts the friction wheel 544. The friction roller 5451a rotates, thereby driving the friction wheel 544 in contact with the friction roller 5451a to rotate synchronously. When the tray 41 of the inspection station rotates to different angles to complete the inspection, the linear drive member drives the turntable 91 to slide, so that the friction roller 5451a gradually moves away from the friction wheel 544, so that the turntable 2 continues to rotate to switch the next tray group 4 to the inspection station.

[0088] In some embodiments, in order to prevent the transmission belt from being separated from the synchronous wheel during transmission, a stop edge group 6 is provided on the first synchronous wheel 51, the second synchronous wheel 52, the third synchronous wheel 53 and the fourth synchronous wheel 542, each stop edge group 6 includes two stop edges 61, and the two stop edges 61 are arranged at intervals along the rotation axis of the bearing tray 41, and the first transmission belt 541 and the second transmission belt 543 are both located between the two stop edges 61 of each stop edge group 6.

[0089] Fig. 7A is a schematic diagram of the connection structure between the support tray and the second driving mechanism of other exemplary embodiments of the present invention; Figure 7B It is a schematic diagram of the connection structure between the friction wheel and the synchronous toothed belt of other exemplary embodiments of the present invention.

[0090] In some other exemplary embodiments of the present invention, Fig. 7A and 7B As shown, the difference between the embodiment of the present invention and the above-mentioned embodiment lies in the different implementation methods of the power component 545.

[0091] Specifically, the power assembly 545 includes: a plurality of second gears 5451b and a synchronous toothed belt 5452b.

[0092] The turntable 91 is slidably arranged on one side of the base 1, and the sliding direction of the turntable 91 is consistent with the radial arrangement direction of the base 1. The three second gears 5451b are all vertically rotatably arranged on the turntable 91 (because the second gear 5451b and the turntable of the detection table 7 share a driving mode, the rotation mode of the second gear 5451b will be described when the CT detection is introduced); the synchronous toothed belt 5452b, the transmission sleeve is arranged on the three second gears 5451b, when the tray assembly 4 rotates to the processing station, the synchronous toothed belt 5452b rotates and contacts with the friction wheel 544.

[0093] It is understandable that when the tray 41 that needs to be rotated to the station to be inspected rotates, the linear drive member drives the turntable 91 to slide, so that the synchronous toothed belt 5452b gradually approaches the friction wheel 544 until the synchronous toothed belt 5452b contacts the friction wheel 544. The second gear 5451b rotates, thereby driving the synchronous toothed belt 5452b meshing with the second gear 5451b to rotate synchronously. When the tray 41 of the station to be inspected rotates to different angles to complete the inspection, the linear drive member drives the turntable 91 to slide, so that the synchronous toothed belt 5452b gradually moves away from the friction wheel 544, so that the turntable surface 2 continues to rotate to switch the next tray group 4 to the station to be inspected.

[0094] It should be noted that the number of the second gears 5451b is not specifically limited in the embodiment of the present invention. For example, the number of the second gears 5451b can be set to two, and the synchronous toothed belt 5452b transmission sleeve is set on the two second gears 5451b. The number of the second gears 5451b can be adjusted according to actual design requirements, and it is ensured that the synchronous toothed belt 5452b on the second gear 5451b can contact the friction wheel 544 to drive the friction wheel 544 to rotate.

[0095] Combine the following Figures 8 to 9C The second working mode of the embodiment of the present invention: the working mode of CT detection is described in detail.

[0096] Figure 8 is a schematic structural diagram of a turntable according to some other exemplary embodiments of the present invention; Fig. 9A is a schematic structural diagram of a revolving table from another perspective according to some other exemplary embodiments of the present invention; Fig. 9B is a schematic diagram of the connection structure between the detection platform, the fixing seat and the friction roller according to some exemplary embodiments of the present invention; Fig. 9C Schematic diagram of the connection structure between the detection platform, the fixing base and the second gear according to some other exemplary embodiments of the present invention.

[0097] like Figure 8 , 9A As shown in FIG9B , the device further includes a rotating assembly, which is disposed on the turntable and is used to drive the detection platform to rotate.

[0098] The rotating assembly includes: a fixed base 10, a plurality of support rods 92 and a rotating member 5452a.

[0099] The fixed seat 10 is rotatably set on the turntable 91; a plurality of support rods 92 are arranged at intervals on the side of the fixed seat 10 away from the turntable 91, one end of the plurality of support rods 92 is detachably connected to the fixed seat 10, and the detection platform 7 is arranged on the end of the support rods 92 away from the fixed seat 10; a rotating member 5452a is arranged on the turntable 91, and the rotating member 5452a is used to drive the fixed seat 10 to rotate.

[0100] Exemplarily, the rotating member 5452a may be a servo motor.

[0101] The fixed seat 10 is rotatably arranged on the turntable 91, and the fixed seat 10 is connected to the output end of the rotating member 5452a on the turntable 91, and the rotating member 5452a can drive the fixed seat 10 to rotate. When the power assembly 545 includes a friction roller 5451a, the central axis of the friction roller 5451a coincides with the rotation axis of the fixed seat 10. The detection table 7 is detachably arranged on the side of the fixed seat 10 away from the turntable 91, and three support rods 92 are arranged on the side of the detection table 7 close to the fixed seat 10. The three support rods 92 are arranged at intervals, and a fixing plate is provided at one end of the support rod 92 away from the detection table 7. Bolts are threadedly assembled on the fixing plate, and thread grooves corresponding to the bolts are provided at the corresponding positions of the fixed seat 10 and the support rods 92, and the free ends of the bolts are threadedly assembled with the thread grooves. A vacant station 8 is provided on the inner side of the turntable 2. When CT detection is required, the turntable 2 is rotated so that the vacant station 8 faces the detection table 7. This is so that CT detection equipment can be placed in the vacant workstation 8 to ensure the normal operation of CT detection.

[0102] Specifically, when performing CT inspection, the inspection platform 7 is mounted on the fixed seat 10 by bolts, and the rotating member 5452a is started, and the rotating member 5452a drives the fixed seat 10 to rotate, thereby driving the inspection platform 7 to rotate, so as to realize CT inspection of the workpiece to be processed on the inspection platform 7. When the inspection platform 7 is not needed to work, the bolts are screwed to separate the support rod 92 from the fixed seat 10. This structure can ensure that when the inspection platform 7 is removed, the friction roller 5451a can also work normally.

[0103] In other embodiments, Fig. 9C As shown, when the power assembly 545 includes the second gear 5451b and the synchronous toothed belt 5452b, one second gear 5451b is arranged on the fixing seat 10 and the central axis of the second gear 5451b coincides with the rotation axis of the fixing seat 10, and the remaining second gears 5451b are rotatably arranged on the turntable 91. This structure can ensure that when the detection table 7 is dismantled, the second gear 5451b and the synchronous toothed belt 5452b can also work normally.
