In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0030] The present invention first provides a dynamic binocular X-ray detection device, such as Figure 1-Figure 3 As shown, it includes a radiation protection device 1 and a detection device arranged inside the radiation protection device 1, and the detection device includes a radiation source component 2, a detector component 3, a spiral CT observation platform 4, a drop machine 5 and a drop platform 6. The radiation protection device 1 adopts a lead room with an automatic lead door 11 for isolating radiation. Two radiation source components 2 and two detector components 3 are provided to form binocular X-ray detection. The ray source assembly 2 includes a first arc guide rail 22 and a ray emitting module 21 slidably mounted on the first arc guide rail 22; the detector assembly 3 includes a second arc guide rail 32 and a detector module 31 slidably mounted on the second arc guide rail 32, the center positions of the first arc guide rail 22 and the second arc guide rail 32 coincide with each other and their openings are opposite to each other, the first arc guide rail 22 and the second arc guide rail 32 are arranged at intervals to form an X-direction channel, and the X-direction channel is arranged through the center position of the circle; the two detector modules 31 correspond to the two ray emitting modules 21 one by one and face the center position of the circle; in the preferred embodiment, the first arc guide rail 22 and the second arc guide rail 32 are located on two arcs on the same circle to facilitate the centering adjustment of the ray source assembly 2 and the detector assembly 3. The spiral CT observation platform 4 is used to clamp the product 100 to be tested and drive the product 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 100 to the center position, where the center position includes the position where the center of the first arc guide rail 22 and the second arc guide rail 32 is located and any position on the Z direction axis where the center of the circle is located, ensuring that the ray source assembly 2 and the detector assembly 3 can obtain the image of the product 100 to be tested. 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 100 to be tested, so as to facilitate rapid positioning. The product 100 to be tested can be a product that needs to undergo a drop test, such as an electronic product mobile phone, tablet, etc. The drop machine 5 is used to absorb the product 100 to be tested in the X-direction channel and drive the product 100 to be tested to rise and fall along the Z-direction. When the product 100 to be tested rises to a specified height along the Z-direction and faces the center of the circle, the drop machine 5 releases the product 100 to be tested and makes it fall; the drop platform 6 can move in the XZ plane to receive the fallen product 100 to be tested, wherein 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.

[0031] The dynamic binocular X-ray detection device provided by the present invention combines a drop machine 5, a ray source assembly 2 and a detector assembly 3. The drop machine 5 is used to perform a drop operation on the product to be tested 100. The ray source assembly 2 and the detector assembly 3 are used to detect the dynamic damage process of the dropped product to be tested 100, thereby realizing dynamic binocular multi-angle X-ray detection of the product to be tested 100, and the detection parameters are more comprehensive and complete; by setting the movement of the spiral CT observation platform 4, the drop machine 5 and the drop platform 6 in the XZ plane, the product to be tested 100 can be detected. 00 is loaded, dropped and received at the center position, so that the product to be tested 100 can fall 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 radiation source component 2 and the detector component 3 for high-frequency image acquisition (picture acquisition) to obtain dynamic damage information of the product to be tested 100 during the falling process, which is beneficial to study the dynamic damage mechanism of the product to be tested 100, and provide a test parameter basis for the optimal design of the product to be tested 100, which can greatly reduce the number of tests, shorten the development cycle and reduce costs.

[0032] In some embodiments, the radiation source assembly 2 also includes a first base 23, a first mounting base plate 24 and a first linear module 25, wherein the first base 23 is provided with two first arc-shaped guide rails 22; two first mounting base plates 24 are provided, and the two first mounting base plates 24 are respectively slidably connected to the two first arc-shaped guide rails 22; two first linear modules 25 are provided, and the two first linear modules 25 are respectively provided on the two first mounting base plates 24, and the axis extension line of the first linear module 25 passes through the center of the circle; two radiation emitting modules 21 are respectively provided on the two first linear modules 25.

[0033] like Figure 4 and Figure 5 As shown, the two ray source assemblies 2 share a first base 23, and the sliding arrangement of the two ray emission modules 21 is realized by setting two first arc-shaped guide rails 22 on the first base 23. The two first arc-shaped guide rails 22 can be a protrusion with an I-shaped cross section or a slide groove, which is used to limit the sliding track of the ray emission module 21. When the ray emission module 21 slides on the first arc-shaped guide rail 22 to adjust the position, the emission direction of the ray emission module 21 is always toward the center position of the circle, that is, along the diameter direction of the first arc-shaped guide rail 22, so as to cooperate with the corresponding detector module 31. By setting the first linear module 25, it is convenient to adjust and control the distance between the ray emission module 21 and the product 100 to be tested, so as to adjust different magnifications and meet the detection requirements of products 100 of multiple sizes to be tested. In order to realize the automatic movement of the ray emission module 21, the first mounting base plate 24 and the first linear module 25 are respectively provided with a first electric drive mechanism.

[0034] In some embodiments, the detector assembly 3 also 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 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 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 extended line of the axis of the second linear module 35 passes through the center of the circle; the two detector modules 31 are respectively arranged on the two second linear modules 35.

[0035] The arrangement and connection 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 facilitates processing and simplifies design costs. The first base 23 and the second base 33 are arranged at intervals to form an X-direction channel, which is used for conveying, loading and dropping of the product 100 to be tested. 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 drive mechanism.

[0036] like Figure 3 and Figure 4 As shown, by setting the first arc guide 22 and the second arc guide 32, the ray emission module 21 and the detector module 31 form two imaging systems in the circumferential direction, and the two imaging systems rotate synchronously to meet the detection of different angles and realize the binocular function. The detection angle range is 60-120°. By setting two first arc guides 22 and two second arc guides 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 limited respectively. Preferably, scale values ​​are provided on one side or both sides of the first arc guide 22 and the second arc guide 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.

[0037] 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 axis 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 100 to be tested.

[0038] like Figure 7As shown, the fourth linear module 42 slides on the third linear module 41 along the X direction, and can drive the product 100 to move toward and away from the center of the circle. The lifting and lowering mounting plate 45 moves up and down along the Z direction on the fourth linear module 42, and can drive the product 100 to move up and down along the Z direction, thereby avoiding objects in the moving direction, and can lift the product 100 to a suitable height so that it can be connected with the drop machine 5 to transfer the product 100 to be tested, so that the drop machine 5 can absorb the product 100 to be tested for the drop test. A rotary motor 46 is fixed on the lifting and lowering mounting plate 45, and the output shaft of the rotary motor 46 is upward along the Z direction. The rotating base plate 43 is installed at the output end of the rotary motor 46. The rotary motor 46 can drive the rotating base plate 43 to rotate, thereby driving the product 100 to be tested on the clamp 44 to rotate to a suitable angle, so as to cooperate with the drop machine 5 to transfer the product 100 to be tested. After the spiral CT observation platform 4 clamps the product 100 to be tested on the outside of the X-direction channel away from the center position of the circle, it passes through the X-direction channel along the X-direction and adjusts the lifting height and rotation angle after reaching the center position of the circle, so that the drop machine 5 can absorb the product 100 to be tested; then the spiral CT observation platform 4 moves in the opposite direction to leave the center position of the circle, and is reset to prepare to clamp the next product 100 to be tested.

[0039] In some embodiments, the dropping 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 slide plate 64 is slidably installed on the fifth linear module 61. The bottom end of the lifting assembly 62 is arranged on the slide plate 64. The top end of the lifting assembly 62 is provided with a lifting base 65. The lifting base 65 is used to receive the fallen product to be tested 100; the protective net 63 is arranged above the lifting base 65 to limit the fallen product to be tested 100 on the lifting base 65.

[0040] like Figure 7As shown, the fifth linear module 61 is used to drive the slide plate 64 to move along the X direction, so that the lifting base 65 can be adjusted to the center position to face the falling product 100 to receive the product 100. The fifth linear module 61 can also be driven by a motor by a combination of a track and a slider. The lifting assembly 62 is used to adjust the height of the lifting base 65, and then cooperate with the drop machine 5 to adjust the falling height of the product 100 to be tested, 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 detection. In this embodiment, the lifting assembly 62 includes a drop drive member 621, a third mounting base plate 622 and a guide shaft 623. The drop drive member 621 takes a linear drive mechanism as an example (it can be an electric cylinder, a pneumatic cylinder or an oil cylinder, etc.). The bottom end of the drop drive member 621 is fixed, and the top end is penetrated by a third mounting base plate 622 connected to the lifting base 65 for driving the lifting base 65 to perform a lifting movement. The third mounting base plate 622 is fixedly assembled with the main body of the drop drive member 621. More than two guide shafts 623 are provided. The top ends of the multiple guide shafts 623 are fixedly connected to the lifting base 65, and the bottom ends are slidably penetrated on the third mounting base plate 622. When the drop drive member 621 drives the lifting base 65 to move up and down, the multiple guide shafts 623 slide along the third mounting base plate 622 to achieve a guiding effect on the lifting base 65. The function of the protective net 63 is to limit the product 100 to be tested within the range of the lifting base 65 when the product 100 falls on the lifting base 65 and bounces up, so that it can be captured by the radiation source assembly 2 and the detector assembly 3 for image acquisition and 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 higher than the upper surface of the lifting base 65 by a certain height in the Z direction to form a limited space area. The protective net 63 is generally a net bag structure.

[0041] In some embodiments, the drop platform 6 further includes a shock absorber 66, which is disposed between the slide plate 64 and the lifting assembly 62. Figure 7 A shock absorber 66 is disposed between the slide plate 64 and the lifting assembly 62 , and when the product 100 to be tested falls on the lifting base 65 , it plays a shock absorbing role to protect the falling driving member 621 and the fifth linear module 61 and other components.

[0042] In some embodiments, the drop machine 5 includes a sixth linear module 51, a lifting rail 52 and a suction cup assembly 53. The sixth linear module 51 is arranged along the X direction and is used for positioning the initial position, so as to facilitate the adjustment of the X-direction drop position of the adsorbed product to be tested 100.

The lifting movement of the suction cup assembly 53 is conducive to approaching the spiral CT observation platform 4 to absorb the product 100 to be tested during the descent process, and then rising to raise the product 100 to the test height.

[0044] In some embodiments, the drop machine 5 also includes a rotating driving member 54, which is slidably arranged on the lifting guide rail 52, and the output end of the rotating driving member 54 is arranged along the Y direction. The suction cup assembly 53 is arranged at the output end of the rotating driving member 54, and the rotating driving member 54 is configured to drive the suction cup assembly 53 to rotate.

[0045] like Figure 8 The rotating driving member 54 is used to adjust the inclination angle of the suction cup assembly 53, combined with Figure 7 , the product to be tested 100 is clamped on the clamping claw 44, the spiral CT observation platform 4 can adjust the rotation angle and height of the product to be tested 100, and the rotating driving member 54 can adjust the inclination angle of the suction cup assembly 53, so that the suction cup assembly 53 can adsorb the appropriate position on the product to be tested 100 to achieve stable adsorption. At the same time, the rotating driving member 54 can adjust the initial position of the adsorbed product to be tested 100, so that the product to be tested 100 is released and dropped at a specified angle to meet the diverse needs of the drop test. The rotating driving member 54 can use a rotating output motor. The suction cup assembly 53 can use a vacuum adsorption assembly to achieve adsorption.

[0046] In some embodiments, the drop machine 5 further includes a lifting drive member 55 , an output end of which is connected to the rotation drive member 54 , and the lifting drive member 55 is configured to drive the rotation drive member 54 to slide on the lifting guide rail 52 .

[0047] like Figure 8 and Fig. 9 Taking the lifting drive member 55 using a rotary drive motor as an example, the lifting drive member 55 is arranged at the bottom end of the lifting guide rail 52, and the output end of the lifting drive member 55 is driven and connected to the rotary drive member 54 by a conveyor belt, a transmission chain or a screw drive.
