Description

Technical Field

[0001] This application relates to the field of foldable screen terminal testing technology, and in particular to a foldable screen terminal fixture and a foldable screen terminal testing device. Background Technology

[0002] With the explosive growth of electronic devices, their functions are becoming increasingly diverse. 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. Currently, electronic devices are single-screen displays; a larger display area means a larger size, thus compromising portability. To balance the size and display area of ​​electronic devices, a foldable structure can be adopted. Electronic devices include a folding mechanism and a flexible display screen. The folding mechanism supports the flexible display screen. The folding mechanism includes a hinge and a screen support. The screen support is rotatably connected to the hinge. A portion of the flexible display screen is connected to the screen support. The folding mechanism in a foldable screen terminal has a complex structure and a large number of components. Foldable screen terminals suffer from problems such as abnormal noises, jamming, or damping deviations during the folding process. Alternatively, during use, the flexible display screen may exhibit dead pixels or black screen issues. Therefore, it is necessary to test foldable screen terminals to analyze the causes of these problems and improve product quality. However, the lack of dedicated fixtures for foldable screen terminals in related technologies affects testing efficiency. Summary of the Invention

[0003] This application provides a foldable screen terminal fixture and a foldable screen terminal testing device. The foldable screen terminal fixture of this application has good adaptability, which helps to ensure reliable and accurate testing results and effectively improves testing efficiency.

[0004] The first aspect of this application provides a foldable screen terminal clamp, which includes a base, a fixing clamping mechanism, a driving component, and an opening and closing clamping mechanism.

[0005] A fixed clamping mechanism is connected to a base. The fixed clamping mechanism includes a first support bracket and a first clamping unit. The first support bracket includes a first non-metallic carrier. The first clamping unit is connected to the first support bracket. The first clamping unit has a first clamping space. The first clamping space is disposed corresponding to the first non-metallic carrier. A drive assembly is connected to the base. The drive assembly includes a power output section. An opening and closing clamping mechanism is connected to the power output section. The opening and closing clamping mechanism includes a second support bracket and a second clamping unit. The second support bracket includes a second non-metallic carrier. The second clamping unit is connected to the second support bracket. The second clamping unit has a second clamping space. The second clamping space is disposed corresponding to the second non-metallic carrier. The drive 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 moves closer to or further away from the first clamping space.

[0006] In this embodiment, when the foldable screen terminal is held by the foldable screen terminal fixture, one frame of the foldable screen terminal can be placed in the first clamping space, and the other frame can be placed in the second clamping space. The first clamping unit and the second clamping unit can respectively clamp the corresponding frames, thereby ensuring that the position of the foldable screen terminal remains stable and is not prone to positional changes during the testing process. The driving component can drive the opening and closing clamping mechanism to rotate relative to the fixed clamping mechanism, so that the foldable screen terminal can be folded and unfolded, thereby effectively simulating the folding and unfolding process of the foldable screen terminal in actual application scenarios. The opening and closing clamping mechanism can control the corresponding frames to hover at any angle, so as to realize the corresponding testing operation on the foldable screen terminal under any opening and closing angle. The foldable screen terminal fixture of this embodiment has good adaptability, meets the requirements of the testing work, and helps to ensure reliable and accurate testing results. When the foldable screen terminal fixture of this embodiment is applied to the testing process, it can effectively improve the testing efficiency. When the foldable screen terminal fixture is held by the foldable screen terminal fixture, the first non-metallic carrier and the second non-metallic carrier of the foldable screen terminal fixture can be respectively set for the two frames of the foldable screen terminal. When the foldable screen terminal testing device according to the embodiments of this application is used to test and analyze the foldable screen terminal, the first non-metallic carrier and the second non-metallic carrier are less likely to generate interference images under the action of radiation. This helps to reduce the possibility of the images generated by the foldable screen terminal fixture and the images of the foldable screen terminal superimposed on each other. It also helps to ensure that the images generated by the foldable screen terminal collected by the foldable screen terminal testing device are clear, accurate and real. This also helps to reduce the difficulty of data analysis, improve the efficiency of data analysis, and improve the accuracy of data analysis results.

[0007] In one possible implementation, the first support bracket includes a first mounting base and a second mounting base spaced apart. The first mounting base is connected to a base. The first and second mounting bases are respectively connected to a first non-metallic carrier. The second support bracket includes a third mounting base and a fourth mounting base spaced apart. The third mounting base is connected to a power output unit. The third and fourth mounting bases are respectively connected to the second non-metallic carrier. The second mounting base is rotatably connected to the fourth mounting base. The rotation axis of the second mounting base coincides with the rotation axis of the power output unit.

[0008] The first and second mounting bases can be manufactured separately, which facilitates structural design according to product requirements, ensures that the mechanical strength and shape of the structure meet product requirements, and helps to reduce 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 base and the fourth mounting base, which helps to improve the positional stability between the fixed clamping mechanism and the opening and closing clamping mechanism, and keeps the relative position of the fixed clamping mechanism and the opening and closing clamping mechanism from changing easily. This makes it less likely for the opening and closing clamping mechanism to shift relative to the fixed clamping mechanism during rotation, and reduces the possibility of pulling or squeezing the foldable screen terminal due to the positional shift of the opening and closing clamping mechanism.

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

[0011] In the case of the foldable screen terminal clamping fixture of this application embodiment, since the second non-metallic carrier can slide relative to the third and fourth mounting seats, the opening and closing clamping mechanism does not impose limiting constraints on the frame of the foldable screen terminal. During the rotation of the frame driven by the opening and closing clamping mechanism, the frame of the foldable screen terminal can apply a force to the second non-metallic carrier, causing the second non-metallic carrier to slide relative to the third and fourth mounting seats along the first direction. This ensures that during the testing process, when the foldable screen terminal switches between the folded and unfolded states, the frame can still normally change position relative to the hinge device. This avoids the flexible display screen, frame, and hinge device of the foldable screen terminal being stretched or squeezed during the rotation of the opening and closing clamping mechanism, reducing the possibility of deformation or structural damage to the flexible display screen, frame, and hinge device affecting the authenticity and accuracy of the test results, and improving the reliability and accuracy of the test results.

[0012] In one possible implementation, the third mounting base includes a first adapter and a second adapter. A 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 unit. The sliding connection points of the first and second adapters are spaced apart from the power output unit along a direction perpendicular to the rotation axis of the power output unit.

[0013] The fourth mounting base includes a third adapter and a fourth adapter. A second non-metallic carrier is slidably connected to the third adapter along a first direction. The third adapter is slidably connected to the fourth adapter along a second direction. The second mounting base 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 foldable screen terminal fixture holds the foldable screen terminal in its unfolded state, both the first and second non-metallic carriers are in predetermined positions. This avoids problems such as the foldable screen terminal failing to unfold properly or over-folding due to excessive bending moment caused by errors in the position of the second non-metallic carrier in the second direction. Over-folding refers to an unfolded state beyond the normal unfolded position. Furthermore, since the thickness of different models of foldable screen terminals in their folded state varies, adjusting the position of the second non-metallic carrier along the second direction can adjust the distance between the first and second non-metallic carriers in their folded state to accommodate the thickness of the foldable screen terminal being tested, thus ensuring that the foldable screen terminal can fold normally.

[0015] In one possible implementation, the materials of the first mounting base, the second mounting base, the third mounting base, and the fourth mounting base are all non-metallic materials, which helps to reduce the possibility of interference images generated by the foldable screen terminal fixture under the action of radiation.

[0016] In one possible implementation, both the first clamping unit and the second clamping unit include a first clamping module and a second clamping module. The first clamping module is located near the base. The second clamping module is located away from the base. The second clamping module includes a position adjustment assembly and a first clamping member. The first clamping member is connected to the position adjustment assembly. The position adjustment assembly is used to move the first clamping member closer to or further away from the first clamping module.

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

[0018] In one possible implementation, the drive component includes a connected screw and a nut. The screw is rotatably connected to a support. A slider is threadedly connected to the screw. The nut is used to drive the screw to rotate, causing the slider to move relative to the screw.

[0019] The threaded connection between the slider and the screw improves the accuracy of slider position adjustment, which in turn improves the accuracy of first clamping member position adjustment, allowing the first clamping member to apply an appropriate force to the frame relatively accurately.

[0020] In one possible implementation, the support base includes a central receiving hole and a shaft hole. The shaft hole communicates with the central receiving hole. A slider is disposed within the central receiving hole. A screw is rotatably connected to the shaft hole.

[0021] The support base can provide good limiting constraints for the slider, ensuring smooth and stable sliding of the slider and avoiding jamming between the slider and the screw.

[0022] In one possible implementation, both the support base and the slider are made of non-metallic materials, which helps to reduce the possibility of interference images generated by the foldable screen terminal fixture under the action of radiation.

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

[0024] In one possible implementation, both the first clamping member and the second clamping member are made of non-metallic materials, which helps to reduce the possibility of interference images generated by the foldable screen terminal clamp under the action of radiation.

[0025] In one possible embodiment, the first clamping member has a first clamping groove and a first clearance groove. The first clamping groove and the first clearance groove are connected. The first clamping groove and the first clearance groove are successively distributed along a first direction. The first clearance groove is disposed away from the power output part. The second clamping member has a second clamping groove and a second clearance groove. The second clamping groove and the second clearance groove are connected. The second clamping groove and the second clearance groove are successively distributed along the first direction. The second clearance groove is disposed away from the power output part. The first clamping groove faces the second clamping groove. The first clearance groove faces the second clearance groove.

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

[0027] When the foldable screen terminal clamp holds the outward-folding foldable screen terminal, the first clearance groove and the second clearance groove can avoid the thickened part of the frame corresponding to the rear camera module, which facilitates the smooth clamping of the outward-folding foldable screen terminal and can also avoid interference between the first clamping member and the second clamping member and the thickened part of the frame.

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

[0029] Different types of foldable screen terminals have different frame sizes. When the driving component moves the first clamping member closer to the second clamping member, and the first clamping member fails to contact the frame when it reaches its limit position, an additional pad needs to be placed between the frame and the first clamping member to allow the first clamping member to press against the frame through the pad. The additional pad can be mounted and fixed on a pad mounting plate to prevent the pad from easily detaching from the first clamping member and falling off when it is not connected.

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

[0031] When the foldable screen terminal is held by the foldable screen terminal fixture, the support blocks provided on the first non-metallic carrier and the second non-metallic carrier can contact the corresponding frame respectively, so that the support blocks can provide support to the corresponding frame and reduce the possibility of the foldable screen terminal shifting position.

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

[0033] When the foldable screen terminal fixture needs to hold the foldable screen terminal, the position of the stop block is pre-adjusted using the position adjustment plate. Then, the foldable screen terminal is clamped onto the fixture. The frame of the foldable screen terminal can contact the stop block to achieve accurate positioning of the foldable screen terminal. This helps improve clamping efficiency, increases the clamping position accuracy of the foldable screen terminal, and ensures that the opening and closing clamping mechanism can smoothly fold the frame during the testing process.

[0034] In one possible implementation, the foldable screen terminal fixture further includes a central positioning rod. The central positioning rod is disposed on the power output unit. The axis of the central positioning rod coincides with the rotation axis of the power output unit.

[0035] When the foldable screen terminal fixture needs to hold the foldable screen terminal, the central positioning rod is used to assist in positioning the foldable screen terminal to achieve accurate positioning of the foldable screen terminal. This helps to improve the efficiency of the clamping work, improve the clamping position accuracy of the foldable screen terminal, and ensure that the opening and closing clamping mechanism can smoothly fold the frame during the testing process.

[0036] A second aspect of this application provides a foldable screen terminal testing device, which includes an X-ray source, a detector, a rotating support stage, and a foldable screen terminal fixture. The X-ray source generates X-rays. The detector is positioned corresponding to the X-ray source and receives X-rays. The rotating support stage is positioned between the X-ray source and the detector. The foldable screen terminal fixture is positioned on the rotating support stage. Both a first clamping space and a second clamping space are positioned corresponding to the X-ray source.

[0037] In one possible implementation, the foldable screen terminal testing device further includes a control unit. The control unit is electrically connected to the drive assembly.

[0038] In one possible implementation, the foldable screen terminal testing device further includes a wireless controller. The wireless controller is communicatively connected to the control device.

[0039] In one possible implementation, the foldable screen terminal testing equipment further includes a slip ring and a mounting platform. A rotating support stage is disposed on the mounting platform. The slip ring includes a rotor, a stator, and conductive brushes. The rotor is disposed on the rotating support stage. The stator is disposed on the mounting platform. The conductive brushes are disposed on the stator. The conductive brushes are electrically connected to the rotor. A drive assembly is electrically connected to the rotor. Attached Figure Description

[0111] The electronic devices in this application embodiment can be referred to as user equipment (UE) or terminals, etc. For example, electronic devices can be portable Android devices (PADs), personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, in-vehicle devices, wearable devices, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, and other mobile or fixed terminals. This application embodiment does not specifically limit the form of the terminal device.

[0112] In this embodiment, a handheld device with wireless communication capabilities is used as an example for explanation. A handheld device with wireless communication capabilities can be, for example, a foldable screen terminal. A foldable screen terminal can be a foldable mobile phone including a foldable flexible display screen.

[0113] Figure 1 The structure of the foldable screen terminal 10 in its unfolded state is shown schematically. Figure 2 The diagram illustrates the structure of the foldable screen terminal 10 in its semi-folded state. Figure 3 This schematically illustrates the structure of a foldable screen terminal in its folded state. See also... Figures 1 to 3 As shown, the foldable 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. Frames 40 may 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 rotate and fold relative to the hinge device 50. In this application, the foldable screen terminal 10 comprising two frames 40 is used as an example for description. When the two frames 40 are stacked on top of each other, the foldable 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 foldable screen terminal 10 is in an unfolded state. The process of the frame 40 moving from the folded state to the unfolded state is the unfolding process, and the process of moving from the unfolded state to the folded state is the folding process.

[0115] In some possible implementations, the frame 40 may include a middle frame. The frame 40 may be connected to the hinge device 50 via the middle frame.

[0116] Figure 4 A partial exploded view of the foldable screen terminal 10 is schematically shown. See also... Figure 4 As shown, the flexible display screen 30 includes a display section for displaying image information. The flexible display screen 30 itself is bendable and can be folded under external force. When the foldable screen terminal 10 is in the unfolded state, the display section of the flexible display screen 30 unfolds to present image information to the user. The display section 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 disposed corresponding to two frames 40. The third display area 33 may be disposed corresponding to the hinge device 50.

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

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

[0119] Electronic components can be housed in the two frames 40 of the foldable screen terminal 10. These electronic components may include, but are not limited to, a processor, memory, or camera module. In some examples, a motherboard is housed within the frame 40. The electronic components are mounted on the motherboard. The motherboard can be a printed circuit board (PCB).

[0120] See Figures 1 to 3 As shown, the foldable screen terminal 10 is an inward-folding foldable screen terminal 10. When the foldable screen terminal 10 is in the folded state, the flexible display screen 30 is folded inward and is not easily observed. Figure 4 The structure of the foldable screen terminal 10 in its unfolded state is shown schematically. Figure 5 This schematically illustrates the structure of a foldable screen terminal in its folded state. See also... Figure 4 and Figure 5 As shown, the foldable screen terminal 10 is an outward-folding foldable screen terminal 10. When the foldable screen terminal 10 is in the folded state, the flexible display screen 30 folds outward and is in a visible state. The outward-folding foldable screen terminal 10 has a rear camera module 170. The frame 40 is thicker at the location of the rear camera module 170.

[0121] In related technologies, due to the large number of components, high structural complexity, and high assembly precision requirements of the hinge device 50, problems such as abnormal noise, jamming, and poor damping are relatively prone to occur during the folding and unfolding process of the foldable screen terminal 10. If the assembly precision between the flexible display screen 30 and the housing 20 is poor, the flexible display screen 30 is relatively prone to defects such as dead pixels or black screens after undergoing numerous bends and unfoldings. For example, the third display area 33 of the flexible display screen 30 is relatively prone to defects such as dead pixels or black screens. Therefore, it is necessary to inspect the foldable screen terminal 10 to analyze the causes of the above problems and improve the product quality of the foldable screen terminal 10. During the inspection process, it is necessary to simulate the folding and unfolding process of the foldable screen terminal 10 by folding at least one of the frames 40. However, the related technologies lack a fixture specifically designed for the foldable screen terminal 10, affecting the inspection efficiency.

[0122] The foldable screen terminal fixture of this application embodiment can be a dedicated fixture for testing foldable screen terminals. During the testing process, the foldable screen terminal fixture can clamp one frame 40 of the foldable screen terminal 10 through a fixed clamping mechanism, and clamp the other frame 40 of the foldable 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, thereby switching the foldable screen terminal 10 between a folded state and an unfolded state. The fixed clamping mechanism and the opening and closing clamping mechanism can stably clamp the foldable screen terminal 10. Folding one of the frames 40 through the opening and closing clamping mechanism simulates the folding and unfolding process of the foldable screen terminal 10. The opening and closing clamping mechanism can control the frame 40 to hover at any angle, so as to realize the corresponding testing operation of the foldable screen terminal 10 under any opening and closing angle. The foldable screen terminal fixture of this application embodiment has good adaptability, meets the requirements of testing work, and helps to ensure reliable and accurate testing results. When the foldable screen terminal fixture of this application embodiment is applied to the testing process, it can effectively improve the testing efficiency.

[0123] The implementation of the foldable screen terminal testing device provided in the embodiments of this application is described below.

[0124] Figure 6 A partial structure of the foldable screen terminal testing device 60 is schematically shown. See also Figure 6 As shown, the foldable screen terminal testing device 60 of this application embodiment includes an X-ray source 70, a detector 80, a rotating support stage 90, and a foldable screen terminal fixture 100.

[0125] A radiation source 70 is used to generate radiation. Exemplarily, the radiation can be X-rays or gamma rays with a certain energy and intensity. A detector 80 is provided corresponding to the radiation source 70. The detector 80 is used to receive radiation. The detector 80 is used to acquire scan data. Exemplarily, the detector 80 can be a flat panel detector. A rotating platform 90 is used to support the foldable screen terminal fixture 100. The rotating platform 90 can be used to drive the foldable screen terminal fixture 100 to rotate. The foldable screen terminal fixture 100 is used to support the foldable screen terminal 10 to be tested.

[0126] The foldable screen terminal testing device 60 of this application embodiment can perform non-destructive testing on the foldable screen terminal 10. The foldable screen terminal testing 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 stereoscopic images without damaging the foldable screen terminal 10. In some examples, the foldable screen terminal testing device 60 can be a computed tomography (CT) device.

[0127] In some feasible methods, the foldable screen terminal 10 to be tested is first clamped and fixed to the foldable screen terminal fixture 100. Then, the detection parameters of the foldable screen terminal detection device 60 are set. The foldable screen terminal fixture 100 is controlled so that the opening angle of the foldable screen terminal 10 is a first angle. The opening angle of the foldable screen terminal 10 can refer to the angle between the first display area 31 and the second display area 32 of the flexible display screen 30. The X-ray source 70 and detector 80 are activated to collect projection data of the foldable screen terminal 10 at the current opening angle. The rotating platform 90 can drive the foldable screen terminal fixture 100 and the foldable screen terminal 10 to rotate synchronously. In some examples, the rotating platform 90 can drive the foldable screen terminal fixture 100 and the foldable screen terminal 10 to rotate synchronously 360°, while the foldable screen terminal detection device 60 scans the foldable screen terminal 10 to obtain an image of the foldable screen terminal 10.

[0128] After completing the projection data acquisition for the foldable screen terminal 10 with an opening angle of the first angle, the foldable screen terminal fixture 100 is controlled to make the opening angle of the foldable screen terminal 10 the second angle. Then, projection data acquisition is performed on the foldable screen terminal 10 with the opening angle of the second angle. This process is repeated until the projection data acquisition is completed for the foldable screen terminal 10 with the opening angle of the Nth angle, where N is an integer.

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

[0130] In some examples, the foldable screen terminal detection device 60 can reconstruct the collected projection data information to create a three-dimensional dynamic video of the opening and closing of the foldable screen terminal 10. This facilitates dynamic analysis of the folding and unfolding process of the foldable screen terminal 10, and allows for accurate and comprehensive analysis of the reasons for problems such as abnormal noise, stuttering, poor damping, dead pixels or black screen on the flexible display screen 30.

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

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

[0133] Figure 7 A partial structure of the foldable screen terminal testing device 60 is shown schematically. Figure 8 A partial structure of the foldable screen terminal fixture 100 is shown schematically. Figure 9 A partial structure of the foldable screen terminal clamp 100 holding the foldable screen terminal 10 is shown schematically. Figure 9 The foldable screen terminal 10 shown is an inward-folding design. See also... Figure 7 , Figure 8 and Figure 9 As shown, the foldable screen terminal fixture 100 of this application embodiment includes a base 110, a fixing clamping mechanism 120, a driving component 130, and an opening and closing clamping mechanism 140. Figure 8 The opening and closing clamping mechanism 140 shown is in the unfolded position. Figure 9 The foldable screen terminal 10 shown is in the unfolded state.

[0134] The base 110 provides a mounting foundation for other structural components. The foldable screen terminal fixture 100 can be connected to the rotating support platform 90 in the foldable screen terminal testing equipment 60 via the base 110.

[0135] A fixed clamping mechanism 120 is connected to a base 110. During the testing process, the fixed clamping mechanism 120 and the base 110 maintain a constant relative position; that is, the fixed clamping mechanism 120 is fixedly connected to the base 110 to maintain its own fixed position. The fixed clamping mechanism 120 includes a first support bracket 121 and a first clamping unit 122. The first clamping unit 122 is connected to the first support bracket 121. The first support bracket 121 includes a first non-metallic carrier 123. The first clamping unit 122 has a first clamping space 122a. When the foldable screen terminal clamp 100 clamps the foldable screen terminal 10, a frame 40 of the foldable 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 corresponds to the first non-metallic carrier 123. With the foldable screen terminal fixture 100 positioned on the rotating support stage 90, the first clamping space 122a is positioned corresponding to the X-ray source 70. The first clamping space 122a is located along the X-ray propagation path.

[0136] In some examples, the material of the first non-metallic carrier 123 can be a transparent material. Exemplarily, the material of the first non-metallic carrier 123 can be polymethyl methacrylate (PMMA), but this application embodiment does not specifically limit this.

[0137] The drive assembly 130 is connected to the base 110. The drive assembly 130 includes a power output section 131. The power output section 131 is capable of rotational motion. The power output section 131 has a rotation axis S.

[0138] The opening and closing clamping mechanism 140 is connected to the power output unit 131. The opening and closing clamping mechanism 140 includes a second support bracket 141 and a second clamping unit 142. The second clamping unit 142 is connected to the second support bracket 141. The second support bracket 141 includes a second non-metallic carrier 143. The second clamping unit 142 has a second clamping space 142a. When the foldable screen terminal clamp 100 clamps the foldable screen terminal 10, a frame 40 of the foldable 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 provided corresponding to the second non-metallic carrier 143. When the foldable screen terminal clamp 100 is mounted on the rotating support stage 90, the second clamping space 142a is provided corresponding to the radiation source 70. The second clamping space 142a is located on the radiation propagation path.

[0139] In some examples, the material of the second non-metallic carrier 143 can be a transparent material. Exemplarily, the material of the second non-metallic carrier 143 can be polymethyl methacrylate (PMMA), but this application embodiment does not specifically limit this.

[0140] Figure 10 A partial structure of the foldable screen terminal fixture 100 is shown schematically. Figure 10 The opening and closing clamping mechanism 140 shown is in the folded position. See also Figure 8 and Figure 10 As shown, the fixed clamping mechanism 120 is disposed on the rotation path of the opening and closing clamping mechanism 140. The driving component 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 moves closer to or further away from the first clamping space 122a of the first clamping unit 122. Under the driving action of the driving component 130, the opening and closing clamping mechanism 140 can switch between an unfolded position and a 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, and thus the foldable screen terminal 10 clamped by the foldable screen terminal fixture 100 is also in the unfolded state. The drive component 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 the 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 the folded state.

[0141] In this embodiment, when the foldable screen terminal 10 is held by the foldable screen terminal fixture 100, one frame 40 of the foldable 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. The first clamping unit 122 and the second clamping unit 142 can respectively clamp the corresponding frame 40, thereby ensuring that the position of the foldable screen terminal 10 remains stable and is not prone to positional changes during the testing 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 foldable screen terminal 10 folds and unfolds, thereby effectively simulating the folding and unfolding process of the foldable screen terminal 10 in actual application scenarios. The opening and closing clamping mechanism 140 can control the corresponding frame 40 to hover at any angle, so as to realize the corresponding testing operation on the foldable screen terminal 10 under any opening and closing angle. The foldable screen terminal fixture 100 of this embodiment has good adaptability, meets the requirements of testing work, and helps to ensure reliable and accurate testing results. When the foldable screen terminal fixture 100 of this application is applied to the inspection process, it can effectively improve the inspection efficiency. When the foldable screen terminal fixture 100 holds the foldable screen terminal 10, the first non-metallic carrier 123 and the second non-metallic carrier 143 of the foldable screen terminal fixture 100 can be respectively set corresponding to the two frames 40 of the foldable screen terminal 10. When the foldable screen terminal inspection equipment 60 of this application is used to inspect and analyze the foldable screen terminal 10, the first non-metallic carrier 123 and the second non-metallic carrier 143 are less likely to produce interfering images under the action of radiation. This helps to reduce the possibility of the images generated by the foldable screen terminal fixture 100 and the images of the foldable screen terminal 10 overlapping, which helps to ensure that the images generated by the foldable screen terminal 10 collected by the foldable screen terminal inspection equipment 60 are clear, accurate, and realistic. This also helps to reduce the difficulty of data analysis, improve the efficiency of data analysis, and improve the accuracy of data analysis results.

[0142] In some feasible ways, the materials of the first non-metallic carrier 123 and the second non-metallic carrier 143 can both be transparent materials, which helps 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] See also some of the possible implementation methods. Figure 8 and Figure 10As shown, the first support bracket 121 includes a first mounting base 124 and a second mounting base 125 spaced apart. The first mounting base 124 is connected to the base 110. The first mounting base 124 can be detachably connected to the base 110. For example, the first mounting base 124 can be connected to the base 110 using fasteners such as screws. The first mounting base 124 and the second mounting base 125 can be manufactured separately, which facilitates structural design according to product requirements, ensures that the mechanical strength and shape of the structure meet product requirements, and helps reduce the overall processing difficulty of the first support bracket 121.

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

[0145] In some examples, the first mounting base 124 can be a sheet metal. The second mounting base 125 can be a sheet metal. The first non-metallic carrier 123 can be a sheet metal.

[0146] In some examples, the materials of the first mounting base 124 and the second mounting base 125 may differ from the material of the first non-metallic carrier 123. The fact that both the first mounting base 124 and the second mounting base 125 are made of non-metallic materials helps reduce the possibility of interference images generated by the foldable screen terminal fixture 100 under radiation. For example, the material of the first mounting base 124 may be, but is not limited to, polyvinyl chloride (PVC). The material of the second mounting base 125 may be, but is not limited to, polyvinyl chloride.

[0147] See Figure 8 and Figure 10As shown, the second support bracket 141 includes a third mounting base 144 and a fourth mounting base 145 spaced apart. The third mounting base 144 is connected to the power output section 131 of the drive assembly 130. The third mounting base 144 and the power output section 131 are detachably connected. For example, the third mounting base 144 and the power output section 131 can be connected by fasteners such as screws. A gap exists between the power output section 131 and the second non-metallic carrier 143 along a direction perpendicular to the rotation axis S of the power output section 131. The power output section 131 can drive the opening and closing clamping mechanism 140 to rotate via the third mounting base 144.

[0148] The third mounting base 144 and the fourth mounting base 145 are respectively connected to the second non-metallic carrier 143. The third mounting base 144 and the fourth mounting base 145 are respectively disposed on both sides of the second non-metallic carrier 143. The third mounting base 144 and the fourth mounting base 145 can be detachably connected to the second non-metallic carrier 143. For example, the third mounting base 144 and the second non-metallic carrier 143, and the fourth mounting base 145 and the second non-metallic carrier 143, can be connected by fasteners such as screws. The third mounting base 144 and the fourth mounting base 145 are located on both sides of the second clamping space 142a, thus avoiding the second clamping space 142a and reducing the possibility of interference images generated by the third mounting base 144 and the fourth mounting base 145 under the influence of radiation.

[0149] In some examples, the third mounting base 144 can be a sheet metal. The fourth mounting base 145 can be a sheet metal. The second non-metallic carrier 143 can be a sheet metal.

[0150] In some examples, the materials of the third mounting base 144 and the fourth mounting base 145 may differ from the material of the second non-metallic carrier 143. The fact that both the third mounting base 144 and the fourth mounting base 145 are made of non-metallic materials helps reduce the likelihood of interference images generated by the foldable screen terminal fixture 100 under radiation. For example, the material of the third mounting base 144 may be, but is not limited to, polyvinyl chloride (PVC). The material of the fourth mounting base 145 may be, but is not limited to, polyvinyl chloride (PVC).

[0151] The second mounting base 125 is rotatably connected to the fourth mounting base 145. The rotation axis of the second mounting base 125 coincides with the rotation axis S of the power output unit 131. The fixed clamping mechanism 120 and the opening and closing clamping mechanism 140 are connected by the second mounting base 125 and the fourth mounting base 145, which helps to improve the positional stability between the fixed clamping mechanism 120 and the opening and closing clamping mechanism 140, keeping the relative positions of the fixed clamping mechanism 120 and the opening and closing clamping mechanism 140 less prone to change. This makes it less likely that the opening and closing clamping mechanism 140 will shift relative to the fixed clamping mechanism 120 during rotation, reducing the possibility of pulling or squeezing the folding screen terminal 10 due to positional 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 base 144 along the first direction X. The second non-metallic carrier 143 is also slidably connected to the fourth mounting base 145 along the first direction X. The first direction X is perpendicular to the rotation axis S of the power output unit 131. When the second non-metallic carrier 143 slides along the first direction X, the second non-metallic carrier 143 moves closer to or further away from the first non-metallic carrier 123.

[0153] For the outward-folding screen terminal 10, if the frame 40 cannot change position normally relative to the hinge device 50, after the frame 40 transitions from the folded state to the unfolded state, the frame 40 will exert a force on the flexible display screen 30 from the edge to the center area. This may cause the third display area 33 of the flexible display screen 30 to be compressed and bulge, resulting in an uneven flexible display screen 30 in the unfolded state and adversely affecting 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 exert a force on the flexible display screen 30 from the center area to the edge, causing the flexible display screen 30 to be stretched and over-tensioned, which will also adversely affect the structure of the flexible display screen 30 itself.

[0154] For the foldable screen terminal 10 with an inward folding design, if the frame 40 cannot change position normally relative to the hinge device 50, after the frame 40 transitions from the folded state to the unfolded state, the frame 40 will exert a force on the flexible display screen 30 from the center area towards the edge. This may cause the third display area 33 of the flexible display screen 30 to be stretched and become over-tensioned, resulting in adverse effects on the structure of the flexible display screen 30 itself in the unfolded state. After the frame 40 transitions from the unfolded state to the folded state, the frame 40 will exert a force on the flexible display screen 30 from the edge towards the center area, causing the flexible display screen 30 to be compressed as a whole, which may also adversely affect the structure of the flexible display screen 30 itself.

[0155] For foldable screen terminals 10 with outward or inward folding designs, if the frame 40 cannot change position normally relative to the hinge device 50, there will be pulling or squeezing forces between the frame 40 and the hinge device 50 when the foldable screen terminal 10 switches between the folded and unfolded states, which will have an adverse effect on the structure of the frame 40 and the hinge device 50.

[0156] Therefore, when the foldable screen terminal clamp 100 of this application holds the foldable screen terminal 10, since the second non-metallic carrier 143 can slide relative to the third mounting base 144 and the fourth mounting base 145, the opening and closing clamping mechanism 140 will not impose a limiting constraint on the frame 40 of the foldable screen terminal 10. During the rotation of the frame 40 driven by the opening and closing clamping mechanism 140, the frame 40 of the foldable screen terminal 10 can apply a force to the second non-metallic carrier 143, so that the second non-metallic carrier 143 slides relative to the third mounting base 144 and the fourth mounting base 145 along the first direction X. This ensures that during the testing process, when the foldable 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. This avoids the flexible display screen 30, the frame 40, and the hinge device 50 of the foldable screen terminal 10 being pulled or squeezed during the rotation of the opening and closing clamping mechanism 140, reducing the possibility of deformation or structural damage to the flexible display screen 30, the frame 40, and the hinge device 50, which would affect the authenticity and accuracy of the test results. This is beneficial to improving the reliability and accuracy of the test results.

[0157] See in some examples Figure 8 , Figure 9 and Figure 10 As shown, the third mounting base 144 includes a first adapter 146 and a second adapter 147. A second non-metallic carrier 143 is slidably connected to the first adapter 146 along a first direction X. The first adapter 146 is slidably connected to the second adapter 147 along a second direction Y. The second direction Y is perpendicular to the rotation axis S of the power output section 131. The first direction X is perpendicular to the second direction Y. The second adapter 147 is connected to the power output section 131 of the drive assembly 130. A sliding connection position formed between the first adapter 146 and the second adapter 147 is spaced apart from the power output section 131 along a direction perpendicular to the rotation axis S of the power output section 131. The fourth mounting base 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 foldable screen terminal clamp 100 holds the foldable screen terminal 10 in its unfolded state, the first non-metallic carrier 123 and the second non-metallic carrier 143 are in predetermined positions. This avoids the problem of the foldable screen terminal 10 failing to be in a normal unfolded state or over-folding due to excessive bending moment caused by an error in the position of the second non-metallic carrier 143 in the second direction Y. Over-folding refers to an over-folded state exceeding the normal unfolded position. In addition, since the thickness of different models of foldable screen terminals 10 in the folded state is different, the distance between the first non-metallic carrier 123 and the second non-metallic carrier 143 in the folded state can be adjusted by adjusting the position of the second non-metallic carrier 143 along the second direction Y, so as to adapt to the thickness of the foldable screen terminal 10 in the folded state to be tested, thereby ensuring that the foldable 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 together. The first plate 146a and the second plate 146b are intersecting. A second non-metallic carrier 143 is slidably connected to the first plate 146a along a first direction X. The first plate 146a is provided with a slide rail 300, and the second non-metallic carrier 143 includes a groove that slidably engages with the slide rail 300. The second plate 146b is slidably connected to a second adapter 147 along a second direction Y. The second adapter 147 is provided with a slide rail 300, and the second plate 146b is provided with a groove that slidably engages with the slide rail 300.

[0160] The third adapter 148 includes a third plate 148a and a fourth plate 148b connected together. The third plate 148a and the fourth plate 148b are intersecting. A second non-metallic carrier 143 is slidably connected to the third plate 148a along a first direction X. The third plate 148a is provided with a slide rail 300, and the second non-metallic carrier 143 includes a groove that slidably engages with the slide rail 300. The second plate 146b faces the fourth plate 148b. The fourth plate 148b is slidably connected to the fourth adapter 149 along a second direction Y. The fourth adapter 149 is provided with a slide rail 300, and the fourth plate 148b is provided with a groove that slidably engages with the slide rail 300.

[0161] In some examples, the materials of the first mounting base 124, the second mounting base 125, the third mounting base 144, and the fourth mounting base 145 are all non-metallic materials, which helps to reduce the possibility of interference images generated by the foldable screen terminal fixture 100 under the action of radiation.

[0162] See also some of the possible implementation methods. Figure 8 , Figure 9 and Figure 10 As shown, both the first clamping unit 122 and the second clamping unit 142 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 move the first clamping member 162 closer to or further 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 support bracket 121. The position of the first clamping module 150 relative to the first support bracket 121 remains fixed. The first clamping module 150 is connected and fixed to the second support bracket 141. The position of the first clamping module 150 relative to the second support bracket 141 remains fixed. Before the foldable screen terminal clamp 100 clamps the foldable screen terminal 10, the position adjustment component 161 moves the first clamping member 162 away from the first clamping module 150 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, making it easier to place the frame 40 between the first clamping member 162 and the first clamping module 150.

[0164] The frame 40 is placed between the first clamping member 162 and the first clamping module 150. Then, the position adjustment component 161 moves the first clamping member 162 closer to the first clamping module 150 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 against the frame 40 from both sides to complete the clamping of the foldable screen terminal 10.

[0165] After the test is completed, the position adjustment component 161 moves the first clamping member 162 away from the first clamping module 150 to increase the distance between the first clamping member 162 and the first clamping module 150, so that the foldable screen terminal 10 can be removed 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 base 163, a slider 164, and a drive member 165. A first support bracket 121 and a second support bracket 141 are respectively provided with the support base 163. The support base 163 can be detachably connected to the first support bracket 121. The support base 163 can be detachably connected to the second support bracket 141. The slider 164 is slidably connected to the support base 163. Both the first direction X and the second direction Y are perpendicular to the sliding direction of the slider 164. The drive member 165 is connected to the slider 164. A 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 drive member 165 is used to drive the slider 164 to slide relative to the support base 163, so that the first clamping member 162 moves closer to or further away from the first clamping module 150.

[0167] Exemplarily, the drive component 165 includes a connected screw 165a and a nut 165b. The screw 165a is rotatably connected to the support base 163. The slider 164 is threadedly connected to the screw 165a. The nut 165b drives the screw 165a to rotate. The slider 164 moves relative to the screw 165a. When the position of the first clamping member 162 needs to be adjusted, the nut 165b is tightened using a tool. The nut 165b drives the screw 165a to rotate relative to the support base 163. The screw 165a can drive the slider 164 to move axially along the screw 165a. The slider 164 drives the first clamping member 162 to move synchronously. The threaded connection between the slider 164 and the screw 165a helps to improve the position adjustment accuracy of the slider 164, thereby improving the position adjustment accuracy of the first clamping member 162, so that the first clamping member 162 can apply an appropriate force to the frame 40 relatively accurately.

[0168] Exemplarily, the support base 163 includes a central receiving hole and a shaft hole. The shaft hole communicates with the central receiving hole. The slider 164 is disposed within the central receiving hole. The screw 165a is rotatably connected to the shaft hole. The support base 163 can provide good limiting constraints for the slider 164, ensuring smooth and stable sliding of the slider 164 and preventing jamming between the slider 164 and the screw 165a. Exemplarily, the support base 163 can be a ring structure.

[0169] In some examples, the materials of the support base 163 and the slider 164 are both non-metallic, which helps to reduce the possibility of interference images generated by the foldable screen terminal fixture 100 under the action of radiation. For example, the materials of the support base 163 and 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 adapter 151 is respectively disposed on the first support bracket 121 and the second support bracket 141. The adapter 151 is detachably connected to the first support bracket 121. The adapter 151 is detachably connected to the second support 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 122a is formed between the first clamping member 162 and the second clamping member 152 disposed on the first support bracket 121. A second clamping space 142a is formed between the first clamping member 162 and the second clamping member 152 disposed on the second support bracket 141.

[0172] In some examples, both the first clamping member 162 and the second clamping member 152 are made of non-metallic materials, which helps to reduce the possibility of interference images generated by the foldable screen terminal fixture 100 under the action of radiation. Exemplarily, the first clamping member 162 is made of rubber. The second clamping member 152 is made of rubber.

[0173] In some examples, Figure 11 A partial structure of the foldable screen terminal fixture 100 is shown schematically. Figure 12 A partial structure of the foldable screen terminal clamp 100 holding the foldable screen terminal 10 is shown schematically. Figure 12 The foldable screen terminal 10 shown is an outward-folding foldable screen terminal 10. See also... Figure 8 , Figure 11 and Figure 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. The first clamping groove 1621 is disposed facing the second clamping groove 153 along the rotation axis S of the power output section 131. When the folding screen terminal clamp 100 clamps the folding screen terminal 10, the frame 40 of the folding screen terminal 10 can be located within the first clamping groove 1621 and the second clamping groove 153, thereby the first clamping member 162 and the second clamping member 152 can form an effective limiting constraint on the frame 40, effectively preventing the folding screen terminal 10 from coming out between the first clamping member 162 and the second clamping member 152.

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

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

[0176] Different types of foldable screen terminals 10 have different frame sizes 40. When the drive unit 165 moves the first clamping member 162 closer to the second clamping member 152, and the first clamping member 162 moves to its limit position but fails to contact the frame 40, an additional pad needs to be provided between the frame 40 and the first clamping member 162 to press the first clamping member 162 against the frame 40. The additional pad can be installed and fixed on the pad mounting plate 180 to prevent the pad from easily detaching from the first clamping member 162 and falling off when it is not connected. For example, the pad can be detachably connected to the pad mounting plate 180 by fasteners such as screws.

[0177] In some examples, the foldable 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 the support block 190. The support block 190 is disposed 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 disposed corresponding to the first clamping space 122a. The position of the support block 190 on the first non-metallic carrier 123 is adjustable. The support block 190 is detachably connected to the second non-metallic carrier 143. The support block 190 is disposed corresponding to the second clamping space 142a. The position of the support block 190 on the second non-metallic carrier 143 is adjustable.

[0178] When the foldable screen terminal clamp 100 clamps the foldable 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 the foldable screen terminal 10 shifting position.

[0179] See also some of the possible implementation methods. Figure 8 and Figure 12 As shown, the foldable screen terminal fixture 100 also includes a stop member 200. The stop member 200 includes a position adjustment plate 201, a connecting plate 202, and a stop block 203. The position adjustment plate 201 and the connecting plate 202 are intersecting. The position adjustment plate 201 is slidably connected to the first support bracket 121. The position adjustment plate 201 can slide relative to the first support bracket 121. The stop block 203 is disposed at the end of the connecting plate 202 away from the position adjustment plate 201. Along the first direction X, the stop block 203 is disposed corresponding to the first clamping space 122a. The material of the stop block 203 is a non-metallic material, which helps to reduce the possibility of the stop block 203 generating interfering images under the action of radiation.

[0180] When the foldable screen terminal fixture 100 needs to clamp the foldable screen terminal 10, the position of the stop block 203 is pre-adjusted by the position adjustment plate 201. Then, the foldable screen terminal 10 is clamped onto the foldable screen terminal fixture 100. The frame 40 of the foldable screen terminal 10 can contact the stop block 203 to achieve accurate positioning of the foldable screen terminal 10. This helps to improve the clamping efficiency, improve the clamping position accuracy of the foldable screen terminal 10, and ensure that the opening and closing clamping mechanism 140 can smoothly fold the frame 40 during the testing process.

[0181] In some examples, the position adjustment plate 201 has a guide hole 2011. A screw is provided on the first support bracket 121. The shank of the screw passes through the guide hole 2011. The head of the screw is used to press the position adjustment plate 201 to fix its position. When it is necessary to change the position of the position adjustment plate 201, the screw is turned to release the head of the position adjustment plate 201, at which point the position adjustment plate 201 can slide relative to the shank. After the position of the position adjustment plate 201 is adjusted, the screw is turned to re-press the head of the position adjustment plate 201.

[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. A position adjustment plate 201 is slidably connected to the adapter 151. The position adjustment plate 201 can slide relative to the adapter 151 along a first direction X.

[0184] See also some of the possible implementation methods. Figure 8 and Figure 12 As shown, the folding screen terminal clamp 100 also includes a central positioning rod 210. The central positioning rod 210 is disposed on the power output part 131 of the drive assembly 130. The axis of the central positioning rod 210 coincides with the rotation axis S of the power output part 131. When the folding screen terminal clamp 100 needs to clamp the folding screen terminal 10, the central 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 beneficial to improve clamping efficiency, improve the clamping position accuracy of the folding screen terminal 10, and ensure that the opening and closing clamping mechanism 140 can smoothly fold the frame 40 during the testing process. In some examples, the end of the central positioning rod 210 facing away from the power output part 131 is tapered. Exemplarily, positioning marks are pre-set on the hinge device 50. When using the central positioning rod 210 for positioning, the axis of the central positioning rod 210 can be aligned with the positioning marks on the hinge device 50 to assist in accurately positioning the position of the folding screen terminal 10.

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

[0186] In some examples, the base 110 is provided with a clearance hole 111, allowing the shaft of the motor 132 to pass through the clearance hole 111. The folding screen terminal fixture 100 also includes a frame 220. The frame 220 is disposed on the base 110. The frame 220 is used to support the opening and closing clamping mechanism 140, thereby preventing the motor 132 from bearing the weight of the opening and closing clamping mechanism 140 and avoiding the possibility of damage to the motor 132 due to bearing a large force. The power output unit 131 is rotatably connected to the frame 220. A coupling 133 is disposed between the frame 220 and the base 110. A second adapter 147 is disposed on the side of the frame 220 opposite to the motor 132.

[0187] The motor 132 drives the opening and closing clamping mechanism 140, allowing for precise control of its rotation angle. For example, the angle control accuracy can be 0.1°, 0.2°, or 0.3°; however, this embodiment does not impose a specific limitation on this.

[0188] The motor 132 can precisely control the opening and closing speed of the clamping mechanism 140 by driving it. For example, the opening and closing speed can be 0.1° / second, 0.2° / second, 1° / second or 2° / second, and this embodiment does not specifically limit it.

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

[0190] When the foldable screen terminal fixture 100 is mounted on the rotating support platform 90, the base 110 of the foldable screen terminal fixture 100 can be connected to the rotating support platform 90 via the support frame 230. The motor 132 is mounted on the rotating support platform 90. The motor 132 is housed within the support frame 230. Exemplarily, the support frame 230 is detachably connected to the rotating support platform 90. For example, the support frame 230 can be connected to the rotating support platform 90 using fasteners such as screws. Exemplarily, the rotation axis of the rotating support platform 90 can coincide with the rotation axis S of the power output unit 131.

[0191] In some feasible ways, Figure 13 A partial structure of the foldable screen terminal testing device 60 is schematically shown. See also Figure 13 As shown, the motor 132 can be electrically connected to an external circuit via a cable to facilitate power supply and signal interaction. The cable may include power lines and signal lines. The foldable screen terminal testing device 60 also includes a control device. The motor 132 can be electrically connected to the control device via a cable.

[0192] In some feasible ways, Figure 14 A partial structure of the foldable screen terminal testing device 60 is shown schematically. Figure 15A partial structure of the foldable screen terminal testing device 60 is schematically shown. See also Figure 14 and Figure 15 As shown, the foldable screen terminal testing device 60 also includes a slip ring 240 and a mounting platform 250. A rotating support table 90 is disposed 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 disposed on the rotating support table 90. The rotor 241 can rotate synchronously with the rotating support table 90. The stator 242 is disposed on the mounting platform 250. The stator 242 can be connected to the mounting platform 250 via a bracket 400 and screws. The stator 242 is connected to the bracket 400. Screws connect the bracket 400 and the mounting platform 250. The conductive brush 243 is disposed 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 support table 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 electrical connection. Specifically, the motor 132 of the drive assembly 130 is electrically connected to the rotor 241. Power can be supplied to the motor 132 and signals can be exchanged through the rotor 241, stator 242 and conductive brushes 243.

[0193] When the rotating platform 90 rotates and drives the folding screen terminal fixture 100 to rotate synchronously, 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 rotate freely by a predetermined angle, improving the rotational flexibility and stability of the rotating platform 90.

[0194] The foldable screen terminal testing equipment 60 also includes a control device 260. The stator 242 of the slip ring 240 can be electrically connected to the control device 260 via a cable.

[0195] In some implementations, 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 rotational speed or rotational position of the opening and closing clamping mechanism 140.

[0196] The control device 260 can control the foldable screen terminal clamp 100 to control the opening angle of the foldable screen terminal 10 to a first angle. After completing the projection data acquisition for the foldable screen terminal 10 with the opening angle of the first angle, the control device 260 can control the foldable screen terminal clamp 100 to control the opening angle of the foldable screen terminal 10 to a second angle. Then, projection data is acquired for the foldable screen terminal 10 with the opening angle of the second angle. This process continues until the projection data acquisition for the foldable screen terminal 10 with the opening angle of the Nth angle is completed.

[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 helps to improve the efficiency of the inspection work.

[0198] In some examples, Figure 16 A partial structure of the foldable screen terminal testing device 60 is schematically shown. See also Figure 16 As shown, the foldable screen terminal testing device 60 also includes a wireless controller 270. The wireless controller 270 is communicatively connected to the control device 260. The control device 260 can be located inside the foldable screen terminal testing device 60. An operator can interact with the control device 260 from outside the foldable screen terminal testing device 60 via the wireless controller 270. The operator can send signals from outside the foldable screen terminal testing device 60 to the control device 260 via the wireless controller 270, enabling the control device 260 to control the foldable screen terminal clamp 100, thereby controlling the opening angle of the foldable screen terminal 10 to a first angle. After completing the projection data acquisition of the foldable screen terminal 10 with the opening angle at the first angle, the operator continues to send signals from the wireless controller 270 to the control device 260, enabling the control device 260 to control the foldable screen terminal clamp 100, causing the opening angle of the foldable screen terminal 10 to be a second angle. Then, projection data is acquired from the foldable screen terminal 10 with the opening angle at the second angle. This process continues until projection data acquisition is completed for the foldable screen terminal 10 with an opening angle of the Nth angle.

[0199] For example, the wireless controller 270 may have a touch display screen to facilitate operators in setting parameters and performing related operations.
