Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of folding screen terminal testing, and in particular to a folding screen terminal fixture and a folding screen terminal detection device. Background Art

[0002] With the explosive growth of electronic devices, electronic devices have more and more functions. The display screen of an electronic device is used to present image information to the user. In some usage scenarios, users expect the display screen of an electronic device to have a larger display area. At present, electronic devices are single-screen displays, and a larger display area means that the size of the electronic device is larger, which makes the electronic device lose portability. In order to balance the size and display area of ​​the electronic device, the electronic device can adopt a folding structure. The electronic device includes a folding device and a flexible display screen. The folding device is used to carry the flexible display screen. The folding device includes a hinge device and a screen support body. The screen support body is rotatably connected to the hinge device. A part of the flexible display screen is connected to the screen support body. The folding device in the folding screen terminal has a complex structure and a large number of parts. The folding screen terminal has problems such as abnormal noise, jamming or damping sense deviation during the folding process. Or, during the use of the folding screen terminal, the flexible display screen has problems such as bad pixels or black screen. Therefore, it is necessary to detect the folding screen terminal to analyze the causes of the above problems, so as to improve the product quality of the folding screen terminal. However, the related art lacks a fixture dedicated to the folding screen terminal, which affects the detection efficiency. Summary of the invention

[0003] The embodiment of the present application provides a folding screen terminal fixture and a folding screen terminal detection device. The folding screen terminal fixture of the embodiment of the present application has good adaptability, which is conducive to ensuring that the detection results are reliable and accurate, and effectively improving the detection efficiency.

[0004] A first aspect of an embodiment of the present application provides a folding screen terminal clamp, which includes a base, a fixed clamping mechanism, a driving assembly and an opening and closing clamping mechanism.

[0005] The fixed clamping mechanism is connected to the base. The fixed clamping mechanism includes a first bearing bracket and a first clamping unit. The first bearing bracket includes a first non-metallic carrier. The first clamping unit is connected to the first bearing bracket. The first clamping unit has a first clamping space. The first clamping space is arranged corresponding to the first non-metallic carrier. The driving assembly is connected to the base. The driving assembly includes a power output part. The opening and closing clamping mechanism is connected to the power output part. The opening and closing clamping mechanism includes a second bearing bracket and a second clamping unit. The second bearing bracket includes a second non-metallic carrier. The second clamping unit is connected to the second bearing bracket. The second clamping unit has a second clamping space. The second clamping space is arranged corresponding to the second non-metallic carrier. The driving assembly is used to drive the opening and closing clamping mechanism to rotate relative to the fixed clamping mechanism so that the second clamping space is close to or away from the first clamping space.

[0006] In the embodiment of the present application, when the folding screen terminal fixture clamps the folding screen terminal, one frame of the folding screen terminal can be placed in the first clamping space, and the other frame is placed in the second clamping space, and the first clamping unit and the second clamping unit can clamp the corresponding frame respectively, so as to ensure that the position of the folding screen terminal remains stable and is not easy to change position during the detection process. The driving component can drive the opening and closing clamping mechanism to rotate relative to the fixed clamping mechanism so that the folding screen terminal can be folded and unfolded, so as to effectively simulate the folding and unfolding process of the folding screen terminal in the actual application scenario. The corresponding frame can be controlled to hover at any angle through the opening and closing clamping mechanism to realize the corresponding detection operation of the folding screen terminal under any opening and closing angle of the folding screen terminal. The folding screen terminal fixture of the embodiment of the present application has good adaptability, meets the requirements of the detection work, and is conducive to ensuring that the detection results are reliable and accurate. When the folding screen terminal fixture of the embodiment of the present application is applied to the detection process, the detection efficiency can be effectively improved. When the folding screen terminal fixture clamps the folding screen terminal, the first non-metallic carrier and the second non-metallic carrier of the folding screen terminal fixture can be respectively set corresponding to the two frames of the folding screen terminal. When the folding screen terminal detection device of the embodiment of the present application is used to detect and analyze the folding screen terminal, the first non-metallic carrier and the second non-metallic carrier are not easy to produce interference images under the action of radiation, which is beneficial to reduce the possibility of superposition of the image generated by the folding screen terminal fixture and the image of the folding screen terminal, and is beneficial to ensure that the image generated by the folding screen terminal collected by the folding screen terminal detection device is clear, accurate and true, which is beneficial to reduce the difficulty of data analysis work, improve the efficiency of data analysis work, and improve the accuracy of data analysis results.

[0007] In a possible embodiment, the first bearing bracket includes a first mounting seat and a second mounting seat arranged at intervals. The first mounting seat is connected to the base. The first mounting seat and the second mounting seat are respectively connected to the first non-metallic carrier. The second bearing bracket includes a third mounting seat and a fourth mounting seat arranged at intervals. The third mounting seat is connected to the power output part. The third mounting seat and the fourth mounting seat are respectively connected to the second non-metallic carrier. The second mounting seat is rotatably connected to the fourth mounting seat. The rotation axis of the second mounting seat coincides with the rotation axis of the power output part.

[0008] The first mounting seat and the second mounting seat can be processed and manufactured separately, which is convenient for structural design according to product requirements, ensuring that the mechanical strength and shape of the structure meet product requirements, which is conducive to reducing the overall processing difficulty of the first load-bearing bracket.

[0009] The fixed clamping mechanism and the opening and closing clamping mechanism are connected by the second mounting seat and the fourth mounting seat, which is beneficial to improving the position stability between the fixed clamping mechanism and the opening and closing clamping mechanism, keeping the relative position of the fixed clamping mechanism and the opening and closing clamping mechanism from changing easily, making it difficult for the opening and closing clamping mechanism to shift position relative to the fixed clamping mechanism during rotation, thereby reducing the possibility of pulling or squeezing the folding screen terminal due to position shift of the opening and closing clamping mechanism.

[0010] In a possible implementation, the second non-metallic carrier is slidably connected to the third mounting seat along a first direction. The second non-metallic carrier is slidably connected to the fourth mounting seat along a first direction. The first direction is perpendicular to the rotation axis of the power output unit.

[0011] When the folding screen terminal clamp of the embodiment of the present application clamps the folding screen terminal, since the second non-metallic carrier can slide relative to the third mounting seat and the fourth mounting seat, the opening and closing clamping mechanism will not form a limit constraint on the frame of the folding screen terminal. During the process of the frame driven by the opening and closing clamping mechanism to rotate, the frame of the folding screen terminal can apply a force to the second non-metallic carrier to make the second non-metallic carrier slide relative to the third mounting seat and the fourth mounting seat along the first direction, so as to ensure that during the detection process, when the folding screen terminal switches between the folded state and the unfolded state, the frame can still change its position relative to the hinge device normally, thereby avoiding the flexible display screen, frame and hinge device of the folding screen terminal from being pulled or squeezed during the rotation of the opening and closing clamping mechanism, reducing the possibility of deformation or structural damage of the flexible display screen, frame and hinge device affecting the authenticity and accuracy of the detection results, which is conducive to improving the reliability and accuracy of the detection results.

[0012] In a possible embodiment, the third mounting seat includes a first adapter and a second adapter. The second non-metallic carrier is slidably connected to the first adapter along a first direction. The first adapter is slidably connected to the second adapter along a second direction. The second adapter is connected to the power output part. In a direction perpendicular to the rotation axis of the power output part, the sliding connection position of the first adapter and the second adapter is spaced from the power output part.

[0013] The fourth mounting seat includes a third adapter and a fourth adapter. The second non-metallic carrier is slidably connected to the third adapter along the first direction. The third adapter is slidably connected to the fourth adapter along the second direction. The second mounting seat is rotatably connected to the fourth adapter. The first direction is perpendicular to the second direction.

[0014] Along the second direction, the position of the second non-metallic carrier can be flexibly adjusted to ensure that when the folding screen terminal fixture clamps the folding screen terminal in the unfolded state, the first non-metallic carrier and the second non-metallic carrier are in the predetermined position, so as to avoid the problem that the folding screen terminal cannot be in the normal unfolded state or over-folds due to the large bending moment caused by the position error of the second non-metallic carrier in the second direction. Over-folding refers to an over-expanded state that exceeds the normal unfolded position. In addition, since the thickness of folding screen terminals in the folded state of different models is different, by adjusting the position of the second non-metallic carrier along the second direction, the distance between the first non-metallic carrier and the second non-metallic carrier in the folded state can be adjusted to adapt to the thickness of the folding screen terminal in the folded state to be tested, thereby ensuring that the folding screen terminal can be folded normally.

[0015] In a possible implementation, the material of the first mounting seat, the material of the second mounting seat, the material of the third mounting seat, and the material of the fourth mounting seat are all non-metallic materials, which helps to reduce the possibility of the folding screen terminal fixture generating interfering images under the action of radiation.

[0016] In a possible embodiment, the first clamping unit and the second clamping unit both include a first clamping module and a second clamping module. The first clamping module is close to the base. The second clamping module is far away from the base. The second clamping module includes a position adjustment component and a first clamping member. The first clamping member is connected to the position adjustment component. The position adjustment component is used to drive the first clamping member to move closer to or away from the first clamping module.

[0017] In a possible embodiment, the position adjustment assembly includes a support seat, a slider and a driving member. The first bearing bracket and the second bearing bracket are respectively provided with support seats. The slider is slidably connected to the support seat. The driving member is connected to the slider. The first clamping member is connected to the slider. The driving member is used to drive the slider to slide relative to the support seat so that the first clamping member moves closer to or away from the first clamping module.

[0018] In a possible implementation, the driving member includes a screw rod and a nut connected to each other. The screw rod is rotatably connected to the support seat. The slider is threadedly connected to the screw rod. The nut is used to drive the screw rod to rotate, and the slider moves relative to the screw rod.

[0019] The threaded connection between the slider and the screw rod is conducive to improving the position adjustment accuracy of the slider, thereby improving the position adjustment accuracy of the first clamping member, so that the first clamping member can relatively accurately apply a force of appropriate size to the frame.

[0020] In a possible implementation, the support seat includes a middle receiving hole and an axial hole. The axial hole is connected to the middle receiving hole. The slider is arranged in the middle receiving hole. The screw rod is rotatably connected to the axial hole.

[0021] The support seat can form a good limit constraint on the slider, ensuring that the slider slides smoothly and stably, and avoiding the problem of jamming between the slider and the screw.

[0022] In a possible implementation, the material of the support base and the material of the slider are both non-metallic materials, which helps to reduce the possibility of the folding screen terminal fixture generating interfering images under the action of radiation.

[0023] In a possible implementation, the first clamping module includes an adapter seat and a second clamping member. The first bearing bracket and the second bearing bracket are respectively provided with the adapter seat. The second clamping member is connected to the adapter seat.

[0024] In a possible implementation, the material of the first clamping member is a non-metallic material, and the material of the second clamping member is a non-metallic material, which helps to reduce the possibility of the folding screen terminal clamp generating interfering images under the action of radiation.

[0025] In a possible embodiment, the first clamping member has a first clamping groove and a first avoidance groove. The first clamping groove is connected to the first avoidance groove. The first clamping groove and the first avoidance groove are distributed successively along the first direction. The first avoidance groove is arranged away from the power output part. The second clamping member has a second clamping groove and a second avoidance groove. The second clamping groove is connected to the second avoidance groove. The second clamping groove and the second avoidance groove are distributed successively along the first direction. The second avoidance groove is arranged away from the power output part. The first clamping groove is arranged facing the second clamping groove. The first avoidance groove is arranged facing the second avoidance groove.

[0026] When the folding screen terminal clamp is clamped by the folding screen terminal, the frame of the folding screen terminal can be located in the first clamping groove and the second clamping groove, so that the first clamping member and the second clamping member can form an effective limiting constraint on the frame, effectively preventing the folding screen terminal from falling out from between the first clamping member and the second clamping member.

[0027] When the folding screen terminal clamp clamps the folding screen terminal with an outward folding design, the first avoidance groove and the second avoidance groove can avoid the increased thickness part of the frame corresponding to the rear camera module, thereby facilitating the smooth clamping of the folding screen terminal with an outward folding design, and also avoiding interference between the first clamping part and the second clamping part and the increased thickness part of the frame.

[0028] In a possible implementation, the folding screen terminal fixture further includes a pad mounting plate. The first bearing bracket and the second bearing bracket are respectively provided with a pad mounting plate. The pad mounting plate is provided between the first clamping module and the second clamping module. The pad mounting plate is provided close to the second clamping module.

[0029] There are differences in the frame sizes of different types of folding screen terminals. When the driving member drives the first clamping member to move closer to the second clamping member, and the first clamping member moves to the extreme position, the first clamping member fails to contact the frame. At this time, it is necessary to set an additional pad between the frame and the first clamping member so that the first clamping member presses the frame through the pad. The additional pad can be installed and fixed on the pad mounting plate to avoid the problem that the pad is in a non-connected state, which makes it easy for the pad to fall out from between the first clamping member and the frame.

[0030] In a possible implementation, the folding screen terminal fixture further includes a support block. The first non-metallic carrier and the second non-metallic carrier are respectively provided with support blocks. The support block is provided between the pad mounting plate and the first clamping module.

[0031] When the folding screen terminal clamp is clamping the folding screen terminal, the support blocks arranged on the first non-metallic carrier and the second non-metallic carrier can respectively contact the corresponding frames, so that the support blocks can provide support to the corresponding frames, reducing the possibility of position displacement of the folding screen terminal.

[0032] In a possible implementation, the folding screen terminal fixture further includes a stopper. The stopper includes a position adjustment plate, a connecting plate, and a stopper block. The position adjustment plate is slidably connected to the first bearing bracket. The stopper block is disposed at an end of the connecting plate away from the position adjustment plate. The stopper block is disposed corresponding to the first clamping space. The material of the stopper block is a non-metallic material.

[0033] When the folding screen terminal fixture needs to clamp the folding screen terminal, the position of the stop block is adjusted in advance through the position adjustment plate. Then the folding screen terminal is clamped on the folding screen terminal fixture, and the frame of the folding screen terminal can contact the stop block to achieve accurate positioning of the folding screen terminal, which is conducive to improving the clamping work efficiency, improving the clamping position accuracy of the folding screen terminal, and ensuring that the opening and closing clamping mechanism can smoothly fold the frame during the detection process.

[0034] In a possible implementation, the folding screen terminal fixture further includes a center positioning rod, which is disposed on the power output part, and whose axis coincides with the rotation axis of the power output part.

[0035] When the folding screen terminal fixture needs to clamp the folding screen terminal, the center positioning rod is used to assist in positioning the folding screen terminal to achieve accurate positioning of the folding screen terminal, which is beneficial to improve the clamping work efficiency, improve the clamping position accuracy of the folding screen terminal, and ensure that the opening and closing clamping mechanism can smoothly fold the frame during the detection process.

[0036] The second aspect of the embodiment of the present application provides a folding screen terminal detection device, which includes a ray source, a detector, a rotating bearing platform and a folding screen terminal fixture. The ray source is used to generate rays. The detector is set corresponding to the ray source. The detector is used to receive rays. The rotating bearing platform is set between the ray source and the detector. The folding screen terminal fixture is set on the rotating bearing platform. The first clamping space and the second clamping space are both set corresponding to the ray source.

[0037] In a possible implementation, the folding screen terminal detection device further includes a control device, which is electrically connected to the driving assembly.

[0038] In a possible implementation, the folding screen terminal detection device further includes a wireless controller, which is communicatively connected to the control device.

[0039] In a possible implementation, the folding screen terminal detection device further includes a slip ring and a mounting platform. The rotating bearing platform is arranged on the mounting platform. The slip ring includes a rotor, a stator and a conductive brush. The rotor is arranged on the rotating bearing platform. The stator is arranged on the mounting platform. The conductive brush is arranged on the stator. The conductive brush is electrically connected to the rotor. The driving assembly is electrically connected to the rotor. BRIEF DESCRIPTION OF THE DRAWINGS

[0111] The electronic device in the embodiment of the present application can be called user equipment (UE) or terminal, etc. For example, the electronic device can be a tablet computer (portable android device, PAD), a personal digital assistant (personal digital assistant, PDA), a handheld device with wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a virtual reality (virtual reality, VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid (smartgrid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smartcity), a wireless terminal in smart home (smart home) and other mobile terminals or fixed terminals. In the embodiment of the present application, the form of the terminal device is not specifically limited.

[0112] In the embodiment of the present application, the electronic device is a handheld device with a wireless communication function as an example for description. The handheld device with a wireless communication function may be, for example, a foldable screen terminal. The foldable screen terminal may be a foldable mobile phone including a foldable flexible display screen.

[0113] Figure 1 The structure of the foldable screen terminal 10 in the unfolded state is schematically shown. Figure 2 The structure of the foldable screen terminal 10 in a half-folded state is schematically shown. Figure 3 The structure of the folding screen terminal 10 in the folded state is schematically shown. Figures 1 to 3 As shown, the folding screen terminal 10 includes a housing 20 and a flexible display screen 30. The housing 20 includes a frame 40 and a hinge device 50. The frame 40 is connected to the hinge device 50. The frame 40 can be respectively provided on opposite sides of the hinge device 50. The flexible display screen 30 is connected to the frame 40.

[0114] The frame 40 can be rotated and folded relative to the hinge device 50. In the present application, the folding screen terminal 10 includes two frames 40 as an example for explanation. When the two frames 40 are stacked on each other, the folding screen terminal 10 is in a folded state. When the two frames 40 move away from each other from the stacked state and unfold to the same plane, the folding screen terminal 10 is in an unfolded state. The process of the frame 40 from the folded state to the unfolded state is the unfolding process, and the process from the unfolded state to the folded state is the folding process.

[0115] In some practicable embodiments, the frame 40 may include a middle frame, and the frame 40 may be connected to the hinge device 50 via the middle frame.

[0116] Figure 4 The partially exploded structure of the foldable screen terminal 10 is schematically shown. Figure 4 As shown, the flexible display screen 30 includes a display unit for displaying image information. The flexible display screen 30 itself has a bendable performance and can be folded after being acted upon by an external force. When the folding screen terminal 10 is in the unfolded state, the display unit of the flexible display screen 30 unfolds to present image information to the user. The display unit may include a first display area 31, a second display area 32, and a third display area 33. The first display area 31 and the second display area 32 are respectively arranged corresponding to the two frames 40. The third display area 33 can be arranged corresponding to the hinge device 50.

[0117] When the two frames 40 are in the folded state, the display unit is in the bent state. The first display area 31 and the second display area 32 of the display unit can be stacked on each other, and the third display area 33 can be bent into an arc state.

[0118] When the two frames 40 are in the unfolded state, the display unit is in the unfolded state, and the first display area 31, the second display area 32 and the third display area 33 can be flat. The folding screen terminal 10 can change its overall size by folding or unfolding, and can also have a larger display area in the unfolded state.

[0119] The two frames 40 of the folding screen terminal 10 may be respectively provided with electronic devices, for example, the electronic devices may include but are not limited to a processor, a memory or a camera module. In some examples, a main board is provided in the frame 40. The electronic devices are provided on the main board. The main board may be a printed circuit board (PCB).

[0120] See also Figures 1 to 3 As shown, the folding screen terminal 10 is an inwardly folding folding screen terminal 10. When the folding screen terminal 10 is in the folded state, the flexible display screen 30 is folded inwardly and is in a state that is not easily observed. Figure 4 The structure of the foldable screen terminal 10 in the unfolded state is schematically shown. Figure 5 The structure of the folding screen terminal 10 in the folded state is schematically shown. Figure 4 and Figure 5 As shown, the folding screen terminal 10 is an external folding design folding screen terminal 10. When the folding screen terminal 10 is in a folded state, the flexible display screen 30 is folded outward and is in an observable state. The external folding design folding screen terminal 10 has a rear camera module 170. The thickness of the frame 40 increases at the position of the rear camera module 170.

[0121] In the related art, since the hinge device 50 itself includes a large number of parts, has a high structural complexity, and has high assembly precision requirements, the hinge device 50 is relatively prone to abnormal noise, jamming, poor damping, and other problems during the folding and unfolding process of the folding screen terminal 10. In the case where the assembly precision of the flexible display screen 30 and the housing 20 is poor, the flexible display screen 30 is relatively prone to problems such as bad pixels or black screens after the flexible display screen 30 has been bent and unfolded for a large number of times. For example, the third display area 33 of the flexible display screen 30 is relatively prone to problems such as bad pixels or black screens. Therefore, it is necessary to detect the folding screen terminal 10 to analyze the causes of the above problems, so as to improve the product quality of the folding screen terminal 10. During the detection process, it is necessary to simulate the folding and unfolding process of the folding screen terminal 10 by folding at least one of the frames 40. However, the related art lacks a fixture dedicated to the folding screen terminal 10, which affects the detection efficiency.

[0122] The folding screen terminal fixture of the embodiment of the present application can be a special fixture for folding screen terminal detection. During the detection process, the folding screen terminal fixture can clamp one frame 40 of the folding screen terminal 10 through a fixed clamping mechanism, and clamp another frame 40 of the folding screen terminal 10 through an opening and closing clamping mechanism. The driving component can drive the opening and closing clamping mechanism to rotate, so that the opening and closing clamping mechanism drives the corresponding frame 40 to fold, so that the folding screen terminal 10 switches between the folded state and the unfolded state. The fixed clamping mechanism and the opening and closing clamping mechanism can stably clamp the folding screen terminal 10. Folding one of the frames 40 through the opening and closing clamping mechanism to simulate the folding and unfolding process of the folding screen terminal 10. The frame 40 can be controlled to hover at any angle through the opening and closing clamping mechanism to realize the corresponding detection operation of the folding screen terminal 10 at any opening and closing angle of the folding screen terminal 10. The folding screen terminal fixture of the embodiment of the present application has good adaptability, meets the requirements of the detection work, and is conducive to ensuring that the detection results are reliable and accurate. When the folding screen terminal fixture of the embodiment of the present application is applied to the detection process, the detection efficiency can be effectively improved.

[0123] The following is an explanation of the implementation method of the folding screen terminal detection device provided in the embodiment of the present application.

[0124] Figure 6 The partial structure of the folding screen terminal detection device 60 is schematically shown. Figure 6 As shown, the folding screen terminal detection device 60 of the embodiment of the present application includes a radiation source 70, a detector 80, a rotating support platform 90 and a folding screen terminal fixture 100.

[0125] The ray source 70 is used to generate rays. For example, the rays can be X-rays or gamma rays with a certain energy and intensity. The detector 80 is set corresponding to the ray source 70. The detector 80 is used to receive rays. The detector 80 is used to collect scanning data. For example, the detector 80 can be a flat-panel detector. The rotating support table 90 is used to carry the folding screen terminal fixture 100. The rotating support table 90 can be used to drive the folding screen terminal fixture 100 to rotate. The folding screen terminal fixture 100 is used to carry the folding screen terminal 10 to be detected.

[0126] The foldable screen terminal detection device 60 of the embodiment of the present application can perform non-destructive testing on the foldable screen terminal 10. The foldable screen terminal detection device 60 can clearly, accurately and directly display the internal structure, composition and defects of the foldable screen terminal 10 in the form of two-dimensional tomographic images or three-dimensional stereo images without damaging the foldable screen terminal 10. In some examples, the foldable screen terminal detection device 60 can be a computerized tomography (CT) device.

[0127] In some feasible ways, the folding screen terminal 10 to be detected is first clamped and fixed on the folding screen terminal fixture 100. Then the detection parameters of the folding screen terminal detection device 60 are set. The folding screen terminal fixture 100 is controlled so that the opening and closing angle of the folding screen terminal 10 is a first angle. The opening and closing angle of the folding screen terminal 10 may refer to the angle between the first display area 31 and the second display area 32 of the flexible display screen 30. Start the ray source 70 and the detector 80 to collect projection data of the folding screen terminal 10 at the current opening and closing angle. The rotating bearing table 90 can drive the folding screen terminal fixture 100 and the folding screen terminal 10 to rotate synchronously. In some examples, the rotating bearing table 90 can drive the folding screen terminal fixture 100 and the folding screen terminal 10 to rotate synchronously by 360°, and the folding screen terminal detection device 60 scans the folding screen terminal 10 to obtain the image of the folding screen terminal 10.

[0128] After completing the projection data collection for the folding screen terminal 10 with the first opening angle, the folding screen terminal fixture 100 is controlled to make the opening angle of the folding screen terminal 10 be the second opening angle. Then, the projection data collection is performed for the folding screen terminal 10 with the second opening angle. And so on, until the projection data collection is completed for the folding screen terminal 10 with the Nth opening angle, where N is an integer.

[0129] Finally, the collected projection data information is reconstructed to form a corresponding two-dimensional tomographic image or a three-dimensional stereoscopic image, and the folding screen terminal 10 is analyzed through the corresponding two-dimensional tomographic image or the three-dimensional stereoscopic image.

[0130] In some examples, the folding screen terminal detection device 60 can reconstruct the collected projection data information to produce a three-dimensional dynamic video of the opening and closing of the folding screen terminal 10, so as to facilitate dynamic analysis of the folding and unfolding process of the folding screen terminal 10, so as to accurately and comprehensively analyze the causes of problems such as abnormal noise, jamming, poor damping, dead pixels or black screen on the flexible display screen 30, etc. in the folding screen terminal 10.

[0131] In some examples, when the foldable screen terminal 10 is in the unfolded state, the opening and closing angle of the foldable screen terminal 10 is the first angle. When the foldable screen terminal 10 is in the folded state, the opening and closing angle of the foldable screen terminal 10 is the Nth angle. Alternatively, when the foldable screen terminal 10 is in the unfolded state, the opening and closing angle of the foldable screen terminal 10 is the Nth angle. When the foldable screen terminal 10 is in the folded state, the opening and closing angle of the foldable screen terminal 10 is the first angle.

[0132] In other examples, the first angle at which the foldable screen terminal 10 is opened and closed is 40°. The Nth angle at which the foldable screen terminal 10 is opened and closed is 30°. Alternatively, the first angle at which the foldable screen terminal 10 is opened and closed is 30°. The Nth angle at which the foldable screen terminal 10 is opened and closed is 40°.

[0133] Figure 7 The partial structure of the folding screen terminal detection device 60 is schematically shown. Figure 8 The partial structure of the folding screen terminal fixture 100 is schematically shown. Fig. 9 The partial structure of the foldable screen terminal fixture 100 clamping the foldable screen terminal 10 is schematically shown. Fig. 9 The folding screen terminal 10 shown in FIG. 1 is a folding screen terminal 10 with an inner folding design. Figure 7 , Figure 8 and Fig. 9 As shown, the folding screen terminal fixture 100 of the embodiment of the present application includes a base 110, a fixed clamping mechanism 120, a driving assembly 130 and an opening and closing clamping mechanism 140. Figure 8 The opening and closing clamping mechanism 140 is shown in the deployed position. Fig. 9 The foldable screen terminal 10 shown in FIG. 1 is in an unfolded state.

[0134] The base 110 is used to provide a mounting base for other structural members. The folding screen terminal fixture 100 can be connected to the rotating bearing platform 90 in the folding screen terminal detection device 60 through the base 110 .

[0135] The fixed clamping mechanism 120 is connected to the base 110. During the detection process, the fixed clamping mechanism 120 and the base 110 maintain a relative position that does not change, that is, the fixed clamping mechanism 120 is connected and fixed to the base 110 to keep the fixed clamping mechanism 120 itself in a fixed position. The fixed clamping mechanism 120 includes a first bearing bracket 121 and a first clamping unit 122. The first clamping unit 122 is connected to the first bearing bracket 121. The first bearing bracket 121 includes a first non-metallic carrier 123. The first clamping unit 122 has a first clamping space 122a. In the case where the folding screen terminal fixture 100 clamps the folding screen terminal 10, a frame 40 of the folding screen terminal 10 can be placed in the first clamping space 122a, and the first clamping unit 122 can clamp the frame 40. The first clamping space 122a is set corresponding to the first non-metallic carrier 123. When the folding screen terminal fixture 100 is arranged on the rotating bearing platform 90, the first clamping space 122a is arranged corresponding to the radiation source 70. The first clamping space 122a is located on the propagation path of the radiation.

[0136] In some examples, the material of the first non-metallic carrier 123 may be a transparent material. For example, the material of the first non-metallic carrier 123 may be polymethyl methacrylate (PMMA), which is not specifically limited in the embodiment of the present application.

[0137] The driving assembly 130 is connected to the base 110. The driving assembly 130 includes a power output part 131. The power output part 131 can perform rotational motion. The power output part 131 has a rotation axis S.

[0138] The opening and closing clamping mechanism 140 is connected to the power output part 131. The opening and closing clamping mechanism 140 includes a second bearing bracket 141 and a second clamping unit 142. The second clamping unit 142 is connected to the second bearing bracket 141. The second bearing bracket 141 includes a second non-metallic carrier 143. The second clamping unit 142 has a second clamping space 142a. In the case where the folding screen terminal fixture 100 clamps the folding screen terminal 10, a frame 40 of the folding screen terminal 10 can be placed in the second clamping space 142a, and the second clamping unit 142 can clamp the frame 40. The second clamping space 142a is set corresponding to the second non-metallic carrier 143. When the folding screen terminal fixture 100 is set on the rotating bearing platform 90, the second clamping space 142a is set corresponding to the radiation source 70. The second clamping space 142a is located on the propagation path of the radiation.

[0139] In some examples, the material of the second non-metallic carrier 143 may be a transparent material. For example, the material of the second non-metallic carrier 143 may be polymethyl methacrylate (PMMA), which is not specifically limited in the embodiment of the present application.

[0140] Fig.10 The partial structure of the folding screen terminal fixture 100 is schematically shown. Fig.10 The opening and closing clamping mechanism 140 is shown in the folded position. Figure 8 and Fig.10 As shown, the fixed clamping mechanism 120 is arranged on the rotation path of the opening and closing clamping mechanism 140. The driving assembly 130 is used to drive the opening and closing clamping mechanism 140 to rotate relative to the fixed clamping mechanism 120, so that the second clamping space 142a of the second clamping unit 142 is close to or away from the first clamping space 122a of the first clamping unit 122. Under the driving action of the driving assembly 130, the opening and closing clamping mechanism 140 can switch between the unfolded position and the folded position. When the opening and closing clamping mechanism 140 is in the unfolded position, the fixed clamping mechanism 120 and the opening and closing clamping mechanism 140 are in the unfolded state, so that the first clamping space 122a is located on one side of the second clamping space 142a, so that the folding screen terminal 10 clamped by the folding screen terminal fixture 100 is also in the unfolded state. The driving assembly 130 can drive the opening and closing clamping mechanism 140 to rotate, and when the opening and closing clamping mechanism 140 is in the folded position, the fixed clamping mechanism 120 and the opening and closing clamping mechanism 140 are in a folded state. At this time, the first clamping space 122a faces the second clamping space 142a, so that the folding screen terminal 10 clamped by the folding screen terminal clamp 100 is also in a folded state.

[0141] In the embodiment of the present application, when the folding screen terminal fixture 100 clamps the folding screen terminal 10, one frame 40 of the folding screen terminal 10 can be placed in the first clamping space 122a, and the other frame 40 can be placed in the second clamping space 142a, and the first clamping unit 122 and the second clamping unit 142 can respectively clamp the corresponding frame 40, so as to ensure that the position of the folding screen terminal 10 remains stable and is not prone to position changes during the detection process. The driving component 130 can drive the opening and closing clamping mechanism 140 to rotate relative to the fixed clamping mechanism 120 so that the folding screen terminal 10 folds and unfolds, thereby effectively simulating the folding and unfolding process of the folding screen terminal 10 in the actual application scenario. The opening and closing clamping mechanism 140 can control the corresponding frame 40 to hover at any angle, so as to realize the corresponding detection operation of the folding screen terminal 10 under any opening and closing angle of the folding screen terminal 10. The folding screen terminal fixture 100 of the embodiment of the present application has good adaptability, meets the requirements of the detection work, and is conducive to ensuring that the detection results are reliable and accurate. When the folding screen terminal fixture 100 of the embodiment of the present application is applied to the detection process, the detection efficiency can be effectively improved. When the folding screen terminal fixture 100 clamps the folding screen terminal 10, the first non-metallic carrier 123 and the second non-metallic carrier 143 of the folding screen terminal fixture 100 can be respectively set corresponding to the two frames 40 of the folding screen terminal 10. When the folding screen terminal detection device 60 of the embodiment of the present application is used to detect and analyze the folding screen terminal 10, the first non-metallic carrier 123 and the second non-metallic carrier 143 are not easy to produce interference images under the action of rays, which is conducive to reducing the possibility of the image generated by the folding screen terminal fixture 100 and the image of the folding screen terminal 10 being superimposed on each other, which is conducive to ensuring that the image generated by the folding screen terminal 10 collected by the folding screen terminal detection device 60 is clear, accurate, and true, which is conducive to reducing the difficulty of data analysis, improving the efficiency of data analysis, and improving the accuracy of data analysis results.

[0142] In some practicable embodiments, the material of the first non-metallic carrier 123 and the material of the second non-metallic carrier 143 may both be transparent materials, which is beneficial to further reduce the possibility of the first non-metallic carrier 123 and the second non-metallic carrier 143 generating interfering images under the action of radiation.

[0143] In some possible implementations, see Figure 8 and Fig.10As shown, the first bearing bracket 121 includes a first mounting seat 124 and a second mounting seat 125 arranged at intervals. The first mounting seat 124 is connected to the base 110. The first mounting seat 124 can be detachably connected to the base 110. For example, the first mounting seat 124 can be connected to the base 110 by fasteners such as screws. The first mounting seat 124 and the second mounting seat 125 can be processed and manufactured separately, which is convenient for structural design according to product requirements, ensuring that the mechanical strength and shape of the structure meet the product requirements, which is conducive to reducing the overall processing difficulty of the first bearing bracket 121.

[0144] The first mounting seat 124 and the second mounting seat 125 are connected to the first non-metallic carrier 123, respectively. The first mounting seat 124 and the second mounting seat 125 can be respectively arranged on both sides of the first non-metallic carrier 123. The first mounting seat 124 and the second mounting seat 125 can be detachably connected to the first non-metallic carrier 123, respectively. For example, the first mounting seat 124 and the first non-metallic carrier 123, and the second mounting seat 125 and the first non-metallic carrier 123 can be connected by fasteners such as screws. The first mounting seat 124 and the second mounting seat 125 are respectively located on both sides of the first clamping space 122a, so that the first mounting seat 124 and the second mounting seat 125 both avoid the first clamping space 122a, reducing the possibility of the first mounting seat 124 and the second mounting seat 125 generating interfering images under the action of radiation.

[0145] In some examples, the first mounting base 124 may be a plate, the second mounting base 125 may be a plate, and the first non-metallic carrier 123 may be a plate.

[0146] In some examples, the material of the first mounting seat 124 and the material of the second mounting seat 125 can be different from the material of the first non-metallic carrier 123. The material of the first mounting seat 124 and the material of the second mounting seat 125 can both be non-metallic materials, which is conducive to reducing the possibility of interference images generated by the folding screen terminal fixture 100 under the action of radiation. Exemplarily, the material of the first mounting seat 124 can be, but not limited to, polyvinyl chloride (PVC). The material of the second mounting seat 125 can be, but not limited to, polyvinyl chloride.

[0147] See also Figure 8 and Fig.10As shown, the second bearing bracket 141 includes a third mounting seat 144 and a fourth mounting seat 145 that are spaced apart. The third mounting seat 144 is connected to the power output part 131 of the driving assembly 130. The third mounting seat 144 is detachably connected to the power output part 131. For example, the third mounting seat 144 and the power output part 131 can be connected by fasteners such as screws. Along a direction perpendicular to the rotation axis S of the power output part 131, there is a spacing between the power output part 131 and the second non-metallic carrier 143. The power output part 131 can drive the opening and closing clamping mechanism 140 to rotate through the third mounting seat 144.

[0148] The third mounting seat 144 and the fourth mounting seat 145 are connected to the second non-metallic carrier 143, respectively. The third mounting seat 144 and the fourth mounting seat 145 are respectively arranged on both sides of the second non-metallic carrier 143. The third mounting seat 144 and the fourth mounting seat 145 can be detachably connected to the second non-metallic carrier 143, respectively. For example, the third mounting seat 144 and the second non-metallic carrier 143, and the fourth mounting seat 145 and the second non-metallic carrier 143 can be connected by fasteners such as screws. The third mounting seat 144 and the fourth mounting seat 145 are respectively located on both sides of the second clamping space 142a, so that the third mounting seat 144 and the fourth mounting seat 145 avoid the second clamping space 142a, reducing the possibility of the third mounting seat 144 and the fourth mounting seat 145 generating interfering images under the action of radiation.

[0149] In some examples, the third mounting base 144 may be a plate, the fourth mounting base 145 may be a plate, and the second non-metallic carrier 143 may be a plate.

[0150] In some examples, the material of the third mounting seat 144 and the material of the fourth mounting seat 145 may be different from the material of the second non-metallic carrier 143. The material of the third mounting seat 144 and the material of the fourth mounting seat 145 may both be non-metallic materials, which is conducive to reducing the possibility of interference images generated by the folding screen terminal fixture 100 under the action of radiation. Exemplarily, the material of the third mounting seat 144 may be, but not limited to, polyvinyl chloride. The material of the fourth mounting seat 145 may be, but not limited to, polyvinyl chloride.

[0151] The second mounting seat 125 is rotatably connected to the fourth mounting seat 145. The rotation axis of the second mounting seat 125 coincides with the rotation axis S of the power output portion 131. The fixed clamping mechanism 120 and the opening and closing clamping mechanism 140 are connected through the second mounting seat 125 and the fourth mounting seat 145, which is conducive to improving the position stability between the fixed clamping mechanism 120 and the opening and closing clamping mechanism 140, and keeping the relative position of the fixed clamping mechanism 120 and the opening and closing clamping mechanism 140 from changing, so that during the rotation of the opening and closing clamping mechanism 140, it is not easy to shift relative to the fixed clamping mechanism 120, and reduce the possibility of pulling or squeezing the folding screen terminal 10 due to the position shift of the opening and closing clamping mechanism 140.

[0152] In some examples, the second non-metallic carrier 143 is slidably connected to the third mounting seat 144 along the first direction X. The second non-metallic carrier 143 is slidably connected to the fourth mounting seat 145 along the first direction X. The first direction X is perpendicular to the rotation axis S of the power output portion 131. When the second non-metallic carrier 143 slides along the first direction X, the second non-metallic carrier 143 approaches or moves away from the first non-metallic carrier 123.

[0153] For the folding screen terminal 10 with an external folding design, when the frame 40 cannot normally change its position relative to the hinge device 50, after the frame 40 transitions from the folded state to the unfolded state, the frame 40 will apply a force from the edge of the flexible display screen 30 to the center area of ​​the flexible display screen 30, so that the third display area 33 of the flexible display screen 30 is squeezed and there is a possibility of bulging, resulting in the unevenness of the flexible display screen 30 in the unfolded state, which has an adverse effect on the structure of the flexible display screen 30 itself. After the frame 40 transitions from the unfolded state to the folded state, the frame 40 will apply a force from the center area of ​​the flexible display screen 30 to the edge of the flexible display screen 30, so that the flexible display screen 30 as a whole is pulled and over-tensioned, which will have an adverse effect on the structure of the flexible display screen 30 itself.

[0154] For the folding screen terminal 10 with an inner folding design, when the frame 40 cannot normally change its position relative to the hinge device 50, after the frame 40 transitions from the folded state to the unfolded state, the frame 40 will apply a force from the center area of ​​the flexible display screen 30 to the edge, so that the third display area 33 of the flexible display screen 30 may be pulled and over-tensioned, resulting in an adverse effect on the structure of the flexible display screen 30 in the unfolded state. After the frame 40 transitions from the unfolded state to the folded state, the frame 40 will apply a force from the edge of the flexible display screen 30 to the center area of ​​the flexible display screen 30, so that the flexible display screen 30 is squeezed as a whole, which will have an adverse effect on the structure of the flexible display screen 30.

[0155] For the folding screen terminal 10 with an external folding design or an internal folding design, when the frame 40 cannot normally change its position relative to the hinge device 50, there is a pulling or squeezing force between the frame 40 and the hinge device 50 when the folding screen terminal 10 switches between the folded state and the unfolded state, which will have an adverse effect on the structure of the frame 40 and the hinge device 50.

[0156] Therefore, when the folding screen terminal clamp 100 of the embodiment of the present application clamps the folding screen terminal 10, since the second non-metallic carrier 143 can slide relative to the third mounting seat 144 and the fourth mounting seat 145, the opening and closing clamping mechanism 140 will not form a limiting constraint on the frame 40 of the folding screen terminal 10. When the opening and closing clamping mechanism 140 drives the frame 40 to rotate, the frame 40 of the folding screen terminal 10 can apply a force to the second non-metallic carrier 143 to make the second non-metallic carrier 143 slide relative to the third mounting seat 144 and the fourth mounting seat 145 along the first direction X, so as to ensure that during the detection process, when the folding screen terminal 10 switches between the folded state and the unfolded state, the frame 40 can still change its position relative to the hinge device 50 normally, thereby avoiding the flexible display screen 30, the frame 40 and the hinge device 50 of the folding screen terminal 10 from being pulled or squeezed during the rotation of the opening and closing clamping mechanism 140, reducing the possibility of deformation or structural damage of the flexible display screen 30, the frame 40 and the hinge device 50 affecting the authenticity and accuracy of the detection results, which is conducive to improving the reliability and accuracy of the detection results.

[0157] For some examples, see Figure 8 , Fig. 9 and Fig.10 As shown, the third mounting seat 144 includes a first adapter 146 and a second adapter 147. The second non-metallic carrier 143 is slidably connected to the first adapter 146 along the first direction X. The first adapter 146 is slidably connected to the second adapter 147 along the second direction Y. The second direction Y is perpendicular to the rotation axis S of the power output part 131. The first direction X is perpendicular to the second direction Y. The second adapter 147 is connected to the power output part 131 of the driving assembly 130. In the direction perpendicular to the rotation axis S of the power output part 131, the sliding connection position formed between the first adapter 146 and the second adapter 147 is spaced from the power output part 131. The fourth mounting seat 145 includes a third adapter 148 and a fourth adapter 149. The second non-metallic carrier 143 is slidably connected to the third adapter 148 along the first direction X. The third adapter 148 is slidably connected to the fourth adapter 149 along the second direction Y. The second mounting base 125 is rotatably connected to the fourth adapter 149 .

[0158] The second non-metallic carrier 143 and the first adapter 146 can slide synchronously relative to the second adapter 147, and the second non-metallic carrier 143 and the third adapter 148 can slide synchronously relative to the fourth adapter 149. Therefore, along the second direction Y, the position of the second non-metallic carrier 143 can be flexibly adjusted to ensure that when the folding screen terminal fixture 100 clamps the folding screen terminal 10 in the unfolded state, the first non-metallic carrier 123 and the second non-metallic carrier 143 are in a predetermined position, avoiding the problem that the folding screen terminal 10 cannot be in a normal unfolded state or is over-folded due to a large bending moment caused by the position error of the second non-metallic carrier 143 in the second direction Y. Over-folding refers to an over-expanded state that exceeds the normal unfolded position. In addition, since the thickness of different models of folding screen terminals 10 in a folded state is different, by adjusting the position of the second non-metallic carrier 143 along the second direction Y, the distance between the first non-metallic carrier 123 and the second non-metallic carrier 143 when they are in the folded state can be adjusted to adapt to the thickness of the folding screen terminal 10 in the folded state currently to be tested, thereby ensuring that the folding screen terminal 10 can be folded normally.

[0159] In some examples, the first adapter 146 includes a first plate 146a and a second plate 146b connected to each other. The first plate 146a and the second plate 146b are arranged to intersect. The second non-metallic carrier 143 is slidably connected to the first plate 146a along the first direction X. The first plate 146a is provided with a slide rail 300, and the second non-metallic carrier 143 includes a slide groove that slidably cooperates with the slide rail 300. The second plate 146b is slidably connected to the second adapter 147 along the second direction Y. The second adapter 147 is provided with a slide rail 300, and the second plate 146b is provided with a slide groove that slidably cooperates with the slide rail 300.

[0160] The third adapter 148 includes a third plate 148a and a fourth plate 148b connected to each other. The third plate 148a and the fourth plate 148b are arranged to intersect. The second non-metallic carrier 143 is slidably connected to the third plate 148a along the first direction X. The third plate 148a is provided with a slide rail 300, and the second non-metallic carrier 143 includes a slide groove that slidably cooperates with the slide rail 300. The second plate 146b is arranged facing the fourth plate 148b. The fourth plate 148b is slidably connected to the fourth adapter 149 along the second direction Y. The fourth adapter 149 is provided with a slide rail 300, and the fourth plate 148b is provided with a slide groove that slidably cooperates with the slide rail 300.

[0161] In some examples, the material of the first mounting seat 124, the material of the second mounting seat 125, the material of the third mounting seat 144 and the material of the fourth mounting seat 145 are all non-metallic materials, which helps to reduce the possibility of the folding screen terminal fixture 100 generating interfering images under the action of radiation.

[0162] In some possible implementations, see Figure 8 , Fig. 9 and Fig.10 As shown, the first clamping unit 122 and the second clamping unit 142 both include a first clamping module 150 and a second clamping module 160. The first clamping module 150 is close to the base 110. The second clamping module 160 is away from the base 110. The second clamping module 160 includes a position adjustment component 161 and a first clamping member 162. The first clamping member 162 is connected to the position adjustment component 161. A corresponding clamping space is formed between the first clamping member 162 and the first clamping module 150. The position adjustment component 161 is used to drive the first clamping member 162 to move closer to or away from the first clamping module 150 to adjust the size of the clamping space.

[0163] The first clamping module 150 is connected and fixed to the first load-bearing bracket 121. The position of the first clamping module 150 relative to the first load-bearing bracket 121 is fixed. The first clamping module 150 is connected and fixed to the second load-bearing bracket 141. The position of the first clamping module 150 relative to the second load-bearing bracket 141 is fixed. Before the folding screen terminal fixture 100 clamps the folding screen terminal 10, the first clamping member 162 is driven to move away from the first clamping module 150 through the position adjustment component 161, so that the distance between the first clamping member 162 and the first clamping module 150 is greater than the size of the frame 40, so as to facilitate the frame 40 to be placed between the first clamping member 162 and the first clamping module 150.

[0164] Place the frame 40 between the first clamping member 162 and the first clamping module 150, and then drive the first clamping member 162 to move closer to the first clamping module 150 through the position adjustment component 161 to reduce the distance between the first clamping member 162 and the first clamping module 150. Finally, the first clamping member 162 and the first clamping module 150 press the frame 40 from both sides of the frame 40 to complete the clamping work of the folding screen terminal 10.

[0165] After the detection is completed, the first clamping member 162 is driven to move away from the first clamping module 150 through the position adjustment component 161 to increase the distance between the first clamping member 162 and the first clamping module 150, thereby facilitating the removal of the folding screen terminal 10 from between the first clamping member 162 and the first clamping module 150.

[0166] In some examples, the position adjustment assembly 161 includes a support seat 163, a slider 164, and a driving member 165. The first bearing bracket 121 and the second bearing bracket 141 are respectively provided with a support seat 163. The support seat 163 can be detachably connected to the first bearing bracket 121. The support seat 163 can be detachably connected to the second bearing bracket 141. The slider 164 is slidably connected to the support seat 163. The first direction X and the second direction Y are both perpendicular to the sliding direction of the slider 164. The driving member 165 is connected to the slider 164. The first clamping member 162 is connected to the slider 164. For example, the first clamping member 162 can be detachably connected to the slider 164 by fasteners such as screws. The driving member 165 is used to drive the slider 164 to slide relative to the support seat 163, so that the first clamping member 162 moves closer to or away from the first clamping module 150.

[0167] Exemplarily, the driving member 165 includes a connected screw rod 165a and a nut 165b. The screw rod 165a is rotatably connected to the support seat 163. The slider 164 is threadedly connected to the screw rod 165a. The screw rod 165a is driven to rotate by the nut 165b. The slider 164 moves relative to the screw rod 165a. When the position of the first clamping member 162 needs to be adjusted, the nut 165b is screwed using a tool. The nut 165b drives the screw rod 165a to rotate relative to the support seat 163. The screw rod 165a can drive the slider 164 to move along the axial direction of the screw rod 165a. The slider 164 drives the first clamping member 162 to move synchronously. The way in which the slider 164 is threadedly connected to the screw rod 165a is conducive to improving the position adjustment accuracy of the slider 164, thereby helping to improve the position adjustment accuracy of the first clamping member 162, so that the first clamping member 162 can relatively accurately apply a force of appropriate size to the frame 40.

[0168] Exemplarily, the support seat 163 includes a middle receiving hole and an axial hole. The axial hole is connected to the middle receiving hole. The slider 164 is disposed in the middle receiving hole. The screw rod 165a is rotatably connected to the axial hole. The support seat 163 can form a good limit constraint on the slider 164, ensuring that the slider 164 slides smoothly and stably, and avoiding the problem of jamming between the slider 164 and the screw rod 165a. Exemplarily, the support seat 163 can be a ring structure.

[0169] In some examples, the material of the support base 163 and the material of the slider 164 are both non-metallic materials, which is conducive to reducing the possibility of interference images generated by the folding screen terminal fixture 100 under the action of radiation. Exemplarily, the material of the support base 163 and the material of the slider 164 are both polyvinyl chloride.

[0170] In some examples, the first clamping module 150 includes an adapter 151 and a second clamping member 152. The first bearing bracket 121 and the second bearing bracket 141 are respectively provided with adapters 151. The adapter 151 is detachably connected to the first bearing bracket 121. The adapter 151 is detachably connected to the second bearing bracket 141. The second clamping member 152 is connected to the adapter 151. Exemplarily, the second clamping member 152 can be detachably connected to the adapter 151 by fasteners such as screws. A corresponding clamping space is formed between the first clamping member 162 and the second clamping member 152.

[0171] A first clamping space 122 a is formed between the first clamping member 162 and the second clamping member 152 disposed on the first supporting bracket 121 . A second clamping space 142 a is formed between the first clamping member 162 and the second clamping member 152 disposed on the second supporting bracket 141 .

[0172] In some examples, the material of the first clamping member 162 is a non-metallic material, and the material of the second clamping member 152 is a non-metallic material, which is conducive to reducing the possibility of the folding screen terminal fixture 100 generating interfering images under the action of radiation. Exemplarily, the material of the first clamping member 162 is rubber. The material of the second clamping member 152 is rubber.

[0173] In some examples, Fig.11 The partial structure of the folding screen terminal fixture 100 is schematically shown. Fig.12 The partial structure of the foldable screen terminal fixture 100 clamping the foldable screen terminal 10 is schematically shown. Fig.12 The folding screen terminal 10 shown in FIG. 1 is a folding screen terminal 10 of an outward folding design. Figure 8 , Fig.11 and Fig.12 As shown, the first clamping member 162 has a first clamping groove 1621. The second clamping member 152 has a second clamping groove 153. Along the rotation axis S of the power output part 131, the first clamping groove 1621 is arranged facing the second clamping groove 153. When the folding screen terminal fixture 100 clamps the folding screen terminal 10, the frame 40 of the folding screen terminal 10 can be located in the first clamping groove 1621 and the second clamping groove 153, so that the first clamping member 162 and the second clamping member 152 can form an effective limit constraint on the frame 40, effectively preventing the folding screen terminal 10 from coming out from between the first clamping member 162 and the second clamping member 152.

[0174] The first clamping member 162 has a first avoidance groove 1622. The first clamping groove 1621 is connected to the first avoidance groove 1622. The first clamping groove 1621 and the first avoidance groove 1622 are distributed successively along the first direction X. The first avoidance groove 1622 is arranged away from the power output part 131. The second clamping member 152 has a second avoidance groove 154. The second clamping groove 153 is connected to the second avoidance groove 154. The second clamping groove 153 and the second avoidance groove 154 are distributed successively along the first direction X. The second avoidance groove 154 is arranged away from the power output part 131. The first avoidance groove 1622 is arranged facing the second avoidance groove 154. The folding screen terminal 10 with an external folding design includes s170. The thickness of the frame 40 increases at the position of the rear camera module 170. When the folding screen terminal fixture 100 clamps the folding screen terminal 10 with an outward folding design, the first avoidance groove 1622 and the second avoidance groove 154 can avoid the increased thickness portion of the frame 40 corresponding to the rear camera module 170, thereby facilitating the smooth clamping of the folding screen terminal 10 with an outward folding design, and also avoiding interference between the first clamping member 162 and the second clamping member 152 and the increased thickness portion of the frame 40.

[0175] For some examples, see Figure 8 and Fig.11 As shown, the folding screen terminal fixture 100 also includes a pad mounting plate 180. The first bearing bracket 121 and the second bearing bracket 141 are respectively provided with a pad mounting plate 180. The pad mounting plate 180 is provided between the first clamping module 150 and the second clamping module 160. The pad mounting plate 180 is provided close to the second clamping module 160.

[0176] There are differences in the size of the frame 40 of different types of folding screen terminals 10. When the driving member 165 drives the first clamping member 162 to move close to the second clamping member 152, and the first clamping member 162 moves to the extreme position, the first clamping member 162 fails to contact the frame 40. At this time, it is necessary to additionally set a pad between the frame 40 and the first clamping member 162 so that the first clamping member 162 presses the frame 40 through the pad. The additional pad can be installed and fixed on the pad mounting plate 180 to avoid the problem that the pad is in a non-connected state, which makes it easy for the pad to fall out from between the first clamping member 162 and the frame 40. Exemplarily, the pad can be detachably connected to the pad mounting plate 180 by fasteners such as screws.

[0177] In some examples, the folding screen terminal fixture 100 also includes a support block 190. The first non-metallic carrier 123 and the second non-metallic carrier 143 are respectively provided with support blocks 190. The support block 190 is arranged between the pad mounting plate 180 and the first clamping module 150. The support block 190 is detachably connected to the first non-metallic carrier 123. The support block 190 is arranged corresponding to the first clamping space 122a. The position of the support block 190 on the first non-metallic carrier 123 can be adjusted. The support block 190 is detachably connected to the second non-metallic carrier 143. The support block 190 is arranged corresponding to the second clamping space 142a. The position of the support block 190 on the second non-metallic carrier 143 can be adjusted.

[0178] When the folding screen terminal clamp 100 clamps the folding screen terminal 10, the support blocks 190 provided on the first non-metallic carrier 123 and the second non-metallic carrier 143 can respectively contact the corresponding frame 40, so that the support blocks 190 can provide support to the corresponding frame 40, reducing the possibility of position displacement of the folding screen terminal 10.

[0179] In some possible implementations, see Figure 8 and Fig.12 As shown, the folding screen terminal fixture 100 also includes a stopper 200. The stopper 200 includes a position adjustment plate 201, a connecting plate 202 and a stopper 203. The position adjustment plate 201 and the connecting plate 202 are arranged to intersect. The position adjustment plate 201 is slidably connected to the first bearing bracket 121. The position adjustment plate 201 can slide relative to the first bearing bracket 121. The stopper 203 is arranged at the end of the connecting plate 202 away from the position adjustment plate 201. Along the first direction X, the stopper 203 is arranged corresponding to the first clamping space 122a. The material of the stopper 203 is a non-metallic material, which is conducive to reducing the possibility of the stopper 203 generating an interfering image under the action of radiation.

[0180] When the folding screen terminal fixture 100 needs to clamp the folding screen terminal 10, the position of the stop block 203 is adjusted in advance through the position adjustment plate 201. Then the folding screen terminal 10 is clamped on the folding screen terminal fixture 100, and the frame 40 of the folding screen terminal 10 can contact the stop block 203 to achieve accurate positioning of the folding screen terminal 10, which is conducive to improving the clamping work efficiency, improving the clamping position accuracy of the folding screen terminal 10, and ensuring that the opening and closing clamping mechanism 140 can smoothly fold the frame 40 during the detection process.

[0181] In some examples, the position adjustment plate 201 has a guide hole 2011. A screw is disposed on the first support bracket 121. The rod of the screw passes through the guide hole 2011. The cap of the screw is used to press the position adjustment plate 201 to fix the position of the position adjustment plate 201. When the position of the position adjustment plate 201 needs to be changed, the screw is screwed so that the cap releases the position adjustment plate 201, and the position adjustment plate 201 can slide relative to the rod. After adjusting the position of the position adjustment plate 201, the screw is screwed so that the cap presses the position adjustment plate 201 again.

[0182] In some examples, the position adjustment plate 201 and the connecting plate 202 are integrally formed. The stop block 203 is detachably connected to the connecting plate 202 .

[0183] In some examples, the first clamping module 150 includes an adapter 151 and a second clamping member 152. The position adjustment plate 201 is slidably connected to the adapter 151. The position adjustment plate 201 can slide along the first direction X relative to the adapter 151.

[0184] In some possible implementations, see Figure 8 and Fig.12 As shown, the folding screen terminal fixture 100 also includes a center positioning rod 210. The center positioning rod 210 is arranged on the power output part 131 of the driving assembly 130. The axis of the center positioning rod 210 coincides with the rotation axis S of the power output part 131. When the folding screen terminal fixture 100 needs to clamp the folding screen terminal 10, the center positioning rod 210 is used to assist in positioning the folding screen terminal 10, so as to achieve accurate positioning of the folding screen terminal 10, which is conducive to improving the clamping work efficiency, improving the clamping position accuracy of the folding screen terminal 10, and ensuring that the opening and closing clamping mechanism 140 can smoothly fold the frame 40 during the detection process. In some examples, the end of the center positioning rod 210 facing away from the power output part 131 is tapered. Exemplarily, a positioning mark point is set on the hinge device 50 in advance. When the center positioning rod 210 is used for positioning, the axis of the center positioning rod 210 can be aligned with the positioning mark point on the hinge device 50 to assist in accurately positioning the position of the folding screen terminal 10.

[0185] In some possible implementations, see Figure 7 , Figure 8 and Fig.12 As shown, the drive assembly 130 also includes a motor 132 and a coupling 133. The power output part 131 is an output shaft. The rotating shaft of the motor 132 itself can be connected to the power output part 131 through the coupling 133 to achieve power transmission. The opening and closing clamping mechanism 140 is connected to the power output part 131. In some examples, the third mounting seat 144 includes a first adapter 146 and a second adapter 147. The second adapter 147 is connected to the power output part 131.

[0186] In some examples, the base 110 is provided with an avoidance hole 111 so that the rotating shaft of the motor 132 can pass through the avoidance hole 111. The folding screen terminal fixture 100 also includes a stand 220. The stand 220 is arranged on the base 110. The stand 220 is used to carry the opening and closing clamping mechanism 140, so as to avoid the motor 132 from bearing the gravity of the opening and closing clamping mechanism 140, and avoid the possibility of damage to the motor 132 due to bearing a large force. The power output part 131 is rotatably connected to the stand 220. The coupling 133 is arranged between the stand 220 and the base 110. The second adapter 147 is arranged on the side of the stand 220 facing away from the motor 132.

[0187] By adopting the driving mode of the motor 132, the motor 132 can accurately control the rotation angle of the opening and closing clamping mechanism 140. For example, the angle control accuracy can be 0.1°, 0.2° or 0.3°, which is not specifically limited in the embodiment of the present application.

[0188] By adopting the driving mode of the motor 132, the motor 132 can also accurately control the opening and closing speed of the opening and closing clamping mechanism 140. For example, the opening and closing speed can be 0.1° / second, 0.2° / second, 1° / second or 2° / second, which is not specifically limited in the embodiment of the present application.

[0189] In some examples, motor 132 may be a servo motor.

[0190] When the folding screen terminal fixture 100 is arranged on the rotating bearing platform 90, the base 110 of the folding screen terminal fixture 100 can be connected to the rotating bearing platform 90 through the support frame 230. The motor 132 is arranged on the rotating bearing platform 90. The motor 132 is arranged in the support frame 230. Exemplarily, the support frame 230 is detachably connected to the rotating bearing platform 90. For example, the support frame 230 can be connected to the rotating bearing platform 90 by fasteners such as screws. Exemplarily, the rotation axis of the rotating bearing platform 90 can coincide with the rotation axis S of the power output unit 131.

[0191] In some achievable ways, Fig.13 The partial structure of the folding screen terminal detection device 60 is schematically shown. Fig.13 As shown, the motor 132 can be electrically connected to the external circuit through a cable to facilitate power supply to the motor 132 and signal interaction. The cable can include a power line and a signal line. The folding screen terminal detection device 60 also includes a control device. The motor 132 can be electrically connected to the control device through a cable.

[0192] In some achievable ways, Fig.14 The partial structure of the folding screen terminal detection device 60 is schematically shown. Fig.15The partial structure of the folding screen terminal detection device 60 is schematically shown. Fig.14 and Fig.15 As shown, the folding screen terminal detection device 60 also includes a slip ring 240 and a mounting platform 250. The rotating bearing platform 90 is arranged on the mounting platform 250. The slip ring 240 includes a rotor 241, a stator 242 and a conductive brush 243. The rotor 241 is arranged on the rotating bearing platform 90. The rotor 241 can rotate synchronously with the rotating bearing platform 90. The stator 242 is arranged on the mounting platform 250. The stator 242 can be connected to the mounting platform 250 through a bracket 400 and a screw. The stator 242 is connected to the bracket 400. The screw connects the bracket 400 and the mounting platform 250. The conductive brush 243 is arranged on the stator 242. The conductive brush 243 is electrically connected to the rotor 241. The drive assembly 130 is electrically connected to the rotor 241. When the rotating bearing platform 90 and the rotor 241 rotate synchronously, the rotor 241 and the conductive brush 243 move relative to each other and the rotor 241 and the conductive brush 243 always maintain a contact and electrical connection state. Specifically, the motor 132 of the driving assembly 130 is electrically connected to the rotor 241. The motor 132 can be powered and signal exchanged through the rotor 241, the stator 242 and the conductive brush 243.

[0193] When the rotating platform 90 rotates itself and drives the folding screen terminal fixture 100 to rotate synchronously as a whole, the rotor 241 of the slip ring 240 rotates relative to the stator 242. Since there is no constraint between the rotor 241 and the stator 242, the rotating platform 90 can freely rotate a predetermined angle, thereby improving the rotation flexibility and stability of the rotating platform 90.

[0194] The folding screen terminal detection device 60 also includes a control device 260. The stator 242 of the slip ring 240 can be electrically connected to the control device 260 through a cable.

[0195] In some achievable embodiments, the control device 260 is electrically connected to the drive assembly 130. Specifically, the control device 260 may be electrically connected to the motor 132. The control device 260 may exchange signals with the drive assembly 130. The control device 260 may control the rotation speed or rotation position of the opening and closing clamping mechanism 140.

[0196] The control device 260 can control the folding screen terminal fixture 100 to control the opening and closing angle of the folding screen terminal 10 to be at a first angle. After completing the projection data acquisition for the folding screen terminal 10 with the opening and closing angle of the first angle, the control device 260 can control the folding screen terminal fixture 100 to control the opening and closing angle of the folding screen terminal 10 to be a second angle. Then, the projection data is collected for the folding screen terminal 10 with the opening and closing angle of the second angle. And so on, until the projection data acquisition is completed for the folding screen terminal 10 with the opening and closing angle of the Nth angle.

[0197] In some examples, the opening and closing angle of the folding screen terminal 10 can be automatically controlled by the control device 260, which is beneficial to improving the efficiency of detection work.

[0198] In some examples, Fig.16 The partial structure of the folding screen terminal detection device 60 is schematically shown. Fig.16 As shown, the folding screen terminal detection device 60 also includes a wireless controller 270. The wireless controller 270 is connected to the control device 260 for communication. The control device 260 can be arranged inside the folding screen terminal detection device 60. The operator can realize signal interaction between the wireless controller 270 and the control device 260 outside the folding screen terminal detection device 60. The operator can send a signal to the control device 260 through the wireless controller 270 outside the folding screen terminal detection device 60, so that the control device 260 can control the folding screen terminal fixture 100 to control the opening and closing angle of the folding screen terminal 10 to be at a first angle. After completing the projection data acquisition of the folding screen terminal 10 with an opening and closing angle of the first angle, continue to send a signal to the control device 260 through the wireless controller 270, so that the control device 260 can control the folding screen terminal fixture 100, so that the opening and closing angle of the folding screen terminal 10 is a second angle. Then the projection data acquisition is performed on the folding screen terminal 10 with an opening and closing angle of the second angle. And so on, until the projection data collection of the folding screen terminal 10 with the opening and closing angle of the Nth angle is completed.

[0199] Exemplarily, the wireless controller 270 may have a touch screen to facilitate operators to set parameters and perform related operations.
