It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings rather than all structures.

Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0065] The present invention first provides a dynamic binocular X-ray detection device, such as Figures 1-3As shown in the figure, it includes a radiation protection device 1 and a detection device arranged inside the radiation protection device 1. The detection device includes a radiation source assembly 2, a detector assembly 3, a spiral CT observation platform 4, a drop tester 5 and a drop platform 6. Among them, the radiation protection device 1 adopts a lead house with an automatic lead door 11 for isolating radiation. There are two radiation source assemblies 2 and two detector assemblies 3 respectively to form binocular X-ray detection. The radiation source assembly 2 includes a first arc-shaped guide rail 22 and a radiation emission module 21 slidably installed on the first arc-shaped guide rail 22; the detector assembly 3 includes a second arc-shaped guide rail 32 and a detector module 31 slidably installed on the second arc-shaped guide rail 32. The center positions of the first arc-shaped guide rail 22 and the second arc-shaped guide rail 32 coincide and the openings face each other. The first arc-shaped guide rail 22 and the second arc-shaped guide rail 32 are arranged at intervals to form an X-direction channel, and the X-direction channel is arranged through the center position; the two detector modules 31 and the two radiation emission modules 21 correspond to each other one by one and face the center position; in a preferred solution, the first arc-shaped guide rail 22 and the second arc-shaped guide rail 32 are on two arcs of the same circle, so as to facilitate the centering adjustment of the radiation source assembly 2 and the detector assembly 3. The spiral CT observation platform 4 is used to clamp the product to be tested 100 and drive the product to be tested 100 to move along the X direction in the X-direction channel; since the X-direction channel passes through the center position, the spiral CT observation platform 4 can send the product to be tested 100 to the center position. The center position here includes the position where the centers of the first arc-shaped guide rail 22 and the second arc-shaped guide rail 32 are located and any position on the Z-axis passing through the center. It is only necessary to ensure that the radiation source assembly 2 and the detector assembly 3 can obtain the image of the product to be tested 100. By defining the center position and the X-direction channel passing through the center position, it is beneficial to control the moving direction of the product to be tested 100, so as to facilitate rapid positioning. The product to be tested 100 can be a product that needs to undergo a drop test, such as an electronic product mobile phone, tablet, etc. The drop tester 5 is used to adsorb the product to be tested 100 in the X-direction channel and drive the product to be tested 100 to lift and lower along the Z direction. When the product to be tested 100 rises to a specified height along the Z direction and faces the center position, the drop tester 5 releases the product to be tested 100 to make it drop; the drop platform 6 can move in the XZ plane to receive the dropped product to be tested 100. Among them, the X direction is along the horizontal direction, the Z direction is along the vertical direction, and the X direction and the Y direction are perpendicular to each other and are both in the horizontal direction.

[0066] The dynamic binocular X-ray detection device provided by the present invention combines a drop tester 5, an X-ray source assembly 2, and a detector assembly 3. The drop tester 5 is used to perform a drop operation on a product under test 100. The X-ray source assembly 2 and the detector assembly 3 are used to detect the dynamic damage process of the dropped product under test 100, thereby realizing the dynamic binocular multi-angle X-ray detection of the product under test 100, and the detection parameters are more comprehensive and complete. By setting the movement of the spiral CT observation platform 4, the drop tester 5, and the drop platform 6 in the XZ plane, the feeding, dropping, and receiving of the product under test 100 at the center position are realized, so that the product under test 100 can drop at the common center position of the first arc guide rail 22 and the second arc guide rail 32, and then can be captured by the X-ray source assembly 2 and the detector assembly 3 for high-frequency image acquisition (image taking) to obtain the dynamic damage information of the product under test 100 during the dropping process, which is beneficial to studying the dynamic damage mechanism of the product under test 100, providing a test parameter basis for the optimized design of the product under test 100, being able to greatly reduce the number of tests, shorten the development cycle, and reduce costs.

[0067] In some embodiments, the X-ray source assembly 2 further includes a first base 23, a first mounting base plate 24, and a first linear module 25. Among them, the first base 23 is provided with two first arc guide rails 22; there are two first mounting base plates 24, and the two first mounting base plates 24 are respectively slidably connected to the two first arc guide rails 22; there are two first linear modules 25, and the two first linear modules 25 are respectively arranged on the two first mounting base plates 24, and the extension line of the axis of the first linear module 25 passes through the center position; the two X-ray emission modules 21 are respectively arranged on the two first linear modules 25.

[0068] As Figure 4 and Figure 5 shown, the two X-ray source assemblies 2 share a first base 23. By setting two first arc guide rails 22 on the first base 23, the sliding setting of the two X-ray emission modules 21 is realized. The two first arc guide rails 22 can be bumps with an I-shaped cross-section or chutes, which are used to define the sliding trajectory of the X-ray emission module 21. When the X-ray emission module 21 slides on the first arc guide rail 22 to adjust the position, the emission direction of the X-ray emission module 21 always faces the center position, that is, along the diameter direction of the first arc guide rail 22, so as to facilitate cooperation with the corresponding detector module 31. By setting the first linear module 25, it is convenient to adjust and control the distance between the X-ray emission module 21 and the product under test 100, so as to adjust different magnification ratios and meet the detection requirements of products under test 100 of different sizes. In order to realize the automatic movement of the X-ray emission module 21, the first mounting base plate 24 and the first linear module 25 respectively have a first electric drive mechanism.

[0069] In some embodiments, the detector assembly 3 further includes a second base 33, a second mounting base plate 34, and a second linear module 35. The second base 33 is provided with two second arc-shaped guide rails 32; there are two second mounting base plates 34, and the two second mounting base plates 34 are respectively slidably connected to the two second arc-shaped guide rails 32; there are two second linear modules 35, and the two second linear modules 35 are respectively arranged on the two second mounting base plates 34, and the extension line of the axis of the second linear module 35 passes through the center position; the two detector modules 31 are respectively arranged on the two second linear modules 35.

[0070] The setting method and connection method of the second base 33, the second mounting base plate 34, and the second linear module 35 are the same as those of the first base 23, the first mounting base plate 24, and the first linear module 25 in the ray source assembly 2, which is convenient for processing and simplifies the design cost. The first base 23 and the second base 33 are arranged at intervals to form an X-direction channel, and the X-direction channel is used for the conveying, loading, and drop receiving of the product to be tested 100. In order to realize the automatic control movement of the detector module 31, the second mounting base plate 34 and the second linear module 35 respectively have a second electric driving mechanism.

[0071] As Figure 3 and Figure 4 As shown, by setting the first arc-shaped guide rail 22 and the second arc-shaped guide rail 32, the ray emission module 21 and the detector module 31 form two imaging systems in the circumferential direction. The two imaging systems rotate synchronously to meet different included angle detections, realize the binocular function, and the detection angle range is 60 - 120°. By setting two first arc-shaped guide rails 22 and two second arc-shaped guide rails 32 with segmented intervals, position interference between the two ray emission modules 21 and between the two detector modules 31 can be avoided, and the movement endpoints of the two ray emission modules 21 and the two detector modules 31 can be respectively restricted. Preferably, scale values are provided on one side or both sides of the first arc-shaped guide rail 22 and the second arc-shaped guide rail 32 to facilitate the adjustment of the initial detection angle position. The detection angle refers to the angle formed by the ray emission directions of the two ray emission modules 21.

[0072] In some embodiments, the spiral CT observation platform 4 includes a third linear module 41, a fourth linear module 42, a rotating base plate 43, and a clamp 44. The third linear module 41 is arranged along the X direction, the fourth linear module 42 is arranged along the Z direction, the fourth linear module 42 is slidably arranged on the third linear module 41, and a lifting mounting plate 45 is slidably arranged on the fourth linear module 42; the rotating base plate 43 is rotatably arranged on the lifting mounting plate 45, and the rotating shaft of the rotating base plate 43 is arranged along the Z direction; the clamp 44 is arranged on the rotating base plate 43 for clamping the product to be tested 100.

[0073] As Figure 7As shown, the fourth linear module 42 slides along the X direction on the third linear module 41, which can drive the product under test 100 to move towards and away from the center position. The lifting mounting plate 45 moves up and down along the Z direction on the fourth linear module 42, which can drive the product under test 100 to move up and down along the Z direction. Furthermore, it can avoid the objects in the moving direction and can lift the product under test 100 to an appropriate height to connect it with the drop tester 5 to transfer the product under test 100, facilitating the drop tester 5 to adsorb the product under test 100 for the drop test. A rotary motor 46 is fixedly installed on the lifting mounting plate 45, and the output shaft of the rotary motor 46 faces upward along the Z direction. The rotary bottom plate 43 is installed at the output end of the rotary motor 46. The rotary motor 46 can drive the rotary bottom plate 43 to rotate, and then drive the product under test 100 on the jaw 44 to rotate to an appropriate angle, so as to cooperate with the drop tester 5 for the transfer of the product under test 100. After the spiral CT observation platform 4 clamps the product under test 100 outside the X-direction channel at a position far from the center, it moves along the X direction through the X-direction channel and after reaching the center position, adjusts the lifting height and rotation angle, so that the drop tester 5 can adsorb the product under test 100; then the spiral CT observation platform 4 moves in the reverse direction away from the center position, and after resetting, it is ready to clamp the next product under test 100.

[0074] In some embodiments, the drop platform 6 includes a fifth linear module 61, a lifting assembly 62, and a protective net 63. The fifth linear module 61 is arranged along the X direction. A sliding plate 64 is slidably installed on the fifth linear module 61. The bottom end of the lifting assembly 62 is arranged on the sliding plate 64, and the top end of the lifting assembly 62 is provided with a lifting base 65 for receiving the dropped product under test 100; the protective net 63 is arranged above the lifting base 65 to limit the dropped product under test 100 on the lifting base 65.

[0075] As Figure 7As shown, the fifth linear module 61 is used to drive the sliding plate 64 to move in the X direction, and thus can adjust the lifting base 65 to the center position to face the to-be-tested product 100 that has fallen to receive the to-be-tested product 100. The fifth linear module 61 can also adopt the cooperation mode of a track and a slider to achieve sliding drive through motor drive. The function of the lifting assembly 62 is to adjust the height of the lifting base 65, and thus cooperate with the dropping machine 5 to adjust the dropping height of the to-be-tested product 100, and can be adjusted according to the detection height of the radiation source assembly 2 and the detector assembly 3, so as to facilitate image acquisition for detection. In this embodiment, the lifting assembly 62 includes a dropping drive member 621, a third mounting base plate 622, and a guide shaft 623. The dropping drive member 621 takes a linear drive mechanism as an example (which can be an electric cylinder, a pneumatic cylinder, an oil cylinder, etc.). The bottom end of the dropping drive member 621 is fixed, and the top end passes through the third mounting base plate 622 and is connected to the lifting base 65 for driving the lifting base 65 to perform lifting motion. The third mounting base plate 622 is fixedly assembled with the body of the dropping drive member 621. There are more than two guide shafts 623. The top ends of the multiple guide shafts 623 are fixedly connected to the lifting base 65, and the bottom ends slide through the third mounting base plate 622. When the dropping drive member 621 drives the lifting base 65 to perform lifting motion, the multiple guide shafts 623 slide along the third mounting base plate 622 to realize the guiding function for the lifting base 65. The function of the protective net 63 is to limit the to-be-tested product 100 within the range of the lifting base 65 when the to-be-tested product 100 bounces after falling on the lifting base 65, so as to be captured by the radiation source assembly 2 and the detector assembly 3 for image acquisition for detection. It can be understood that the bottom end of the protective net 63 is connected to the edge of the lifting base 65, and the protective net 63 is a certain height higher than the upper surface of the lifting base 65 in the Z direction to form a limited space area. The protective net 63 is generally of a net pocket structure.

[0076] In some embodiments, the dropping platform 6 further includes a shock absorber 66, and the shock absorber 66 is arranged between the sliding plate 64 and the lifting assembly 62. As Figure 7 , a shock absorber 66 is arranged between the sliding plate 64 and the lifting assembly 62. When the to-be-tested product 100 falls on the lifting base 65, it plays a shock-absorbing role to protect components such as the dropping drive member 621 and the fifth linear module 61.

[0077] In some embodiments, the dropping machine 5 includes a sixth linear module 51, a lifting guide rail 52, and a suction cup assembly 53. The sixth linear module 51 is arranged in the X direction and is used for initial position positioning to facilitate the adjustment of the X-direction dropping position of the adsorbed to-be-tested product 100. A connecting plate 511 is slidably arranged on the sixth linear module 51. The lifting guide rail 52 is arranged in the Z direction, and the lifting guide rail 52 is arranged on the connecting plate 511; the suction cup assembly 53 is slidably arranged on the lifting guide rail 52 to drive the to-be-tested product 100 to lift, so as to realize the adjustment of the Z-direction position of the to-be-tested product 100 before dropping.

[0078] AsFigure 7 and Figure 8 As shown in, in combination with Figure 2 , the lifting guide rail 52 can be arranged on one side of the sixth linear module 51 facing the dropping platform 6 through the connecting plate 511, and the suction cup assembly 53 is arranged on one side of the lifting guide rail 52 facing the dropping platform 6, so that the product 100 to be tested can be adjusted to directly above the center position for the dropping test. The lifting movement of the suction cup assembly 53 is conducive to approaching the spiral CT observation platform 4 during the descending process to adsorb the product 100 to be tested, and then rising to lift the product 100 to the test height.

[0079] In some embodiments, the dropping machine 5 further includes a rotation driving member 54. The rotation driving member 54 is slidably arranged on the lifting guide rail 52. The output end of the rotation driving member 54 is arranged along the Y direction. The suction cup assembly 53 is arranged at the output end of the rotation driving member 54, and the rotation driving member 54 is configured to drive the suction cup assembly 53 to rotate.

[0080] As Figure 8 shown, the rotation driving member 54 is used to adjust the inclination angle of the suction cup assembly 53. In combination with Figure 7 , the product 100 to be tested is clamped on the clamping jaw 44. The spiral CT observation platform 4 can adjust the rotation angle and height of the product 100 to be tested. The rotation driving member 54 can adjust the inclination angle of the suction cup assembly 53, so that the suction cup assembly 53 can adsorb the product 100 to be tested at a suitable position to achieve stable adsorption. At the same time, the rotation driving member 54 can adjust the initial position of the adsorbed product 100 to be tested, so that the product 100 to be tested is released and dropped at a specified angle, meeting the diverse requirements of the dropping test.
