[0001] This application relates to the field of display screen testing technology, and in particular to a display screen touch press durability testing device. Background Technology

[0002] Display screen testing is conducted to evaluate the performance, reliability, and durability of a display screen.

[0003] In related technologies, display durability testing devices repeatedly scribble, tap, and press on the display surface using drive contacts to simulate long-term user use scenarios. However, existing display durability testing devices suffer from insufficient synchronization between multiple stations during multi-station testing, leading to deviations in test results across multiple stations. Summary of the Invention

[0004] This application provides a display screen touch press durability testing device, which can improve the technical problem in the related art where the lack of synchronization between the various stations during multi-station display screen touch press durability testing leads to deviations in the test results of each station.

[0005] This application provides a display screen touch press durability testing device, including: A rack having a test plane for mounting a display screen; the test plane is perpendicular to the height direction of the rack. A first drive unit is mounted on the frame; A movable stage is mounted on the first driving device and located above the test plane; the first driving device can drive the movable stage to move along the height direction of the frame to change the distance between the movable stage and the test plane; the movable stage can rotate about a first axis to change the angle between the movable stage and the test plane; the first axis is located at the end of the movable stage and is parallel to the width direction of the movable stage. Multiple contact elements are spaced apart on the movable platform; the contact ends of the contact elements protrude from the side of the movable platform facing the test plane and are used to contact the display screen; the contact ends of the contact elements are all located on the same plane parallel to the test plane; the projections of the contact ends of the multiple contact elements on the test plane along the height direction of the frame are spaced apart. Multiple shifting components are movably disposed on the moving platform along the length direction of the moving platform; the multiple shifting components are connected to the contact component in a one-to-one correspondence; The shifting member is used to change the distance of each contact to the first axis when the contact and the test plane form different angles, so that the projection position of the contact end of each contact on the test plane along the height direction of the frame is the same as the projection position of the contact end of each contact on the test plane along the height direction of the frame when the contact and the test plane form different angles.

[0006] The technical solutions described in this application embodiment have at least the following technical effects: The display screen touch press durability testing device provided in this application adjusts the distance between the moving stage and the test plane through a first driving device. The moving stage rotates to change the angle between the contact and the test plane, and the shifting member moves along the length of the moving stage to change the projection position of the contact end of the contact on the test plane along the height direction of the frame. This ensures that when the moving stage rotates to different angles, the projection position of the contact end of the contact on the test plane along the height direction of the frame is the same. This achieves that when the angle of the contact changes, the contact end of the contact abuts the display screen at the same position, effectively correcting the contact point offset caused by angle adjustment. This allows multiple stations to apply the same pressure synchronously, maintains the synchronicity of multiple stations, and improves the consistency of test results.

The elastic force of the multiple elastic elements decreases as the distance from the fixed end of the elastic element to the fixed end of the flipping table increases; the elastic elements are used to make the slide move a different distance toward the fixed end of the flipping table when the angle between the flipping table surface and the test plane is different, thereby making the projection position of the contact end of the contact element on the test plane along the height direction of the frame the same.

[0011] In some embodiments, the contact includes: A connecting rod passes through the movable stage; the contact end of the connecting rod near the test plane protrudes from the side of the movable stage facing the test plane.

[0026] In related technologies, display durability testing devices repeatedly scribble, tap, and press on the display surface using drive contacts to simulate long-term user use scenarios. However, existing display durability testing devices suffer from insufficient synchronization between multiple stations during multi-station testing, leading to deviations in test results across multiple stations.

[0027] Based on this, in order to improve the technical problem that insufficient synchronization of each station leads to deviations in the test results of each station when conducting multi-station display screen touch press durability tests in related technologies, the embodiments of this application provide the following solution.

[0028] Please refer to the following: Figures 1 to 4This application provides a display screen touch press durability testing device 100. The display screen touch press durability testing device 100 includes a frame 10, a first driving device 20, a moving stage 30, multiple contact elements 40, and multiple displacement elements 50. The frame 10 has a test plane 101; the test plane 101 is perpendicular to the height direction of the frame 10; the first driving device 20 is disposed on the frame 10; the moving stage 30 is disposed on the first driving device 20 and located above the test plane 101; the first driving device 20 can drive the moving stage 30 to move along the height direction C of the frame to change the distance between the moving stage 30 and the test plane 101; the moving stage 30 can rotate around a first axis to change the angle between the moving stage 30 and the test plane 101; the first axis is located at the end of the moving stage 30 and is parallel to the width direction of the moving stage 30; multiple contact elements 40 are spaced apart on the moving stage 30; the contact elements... End 401 protrudes from the side of the moving stage 30 facing the test plane 101 and is used to contact the display screen 200; the contact ends 401 of the contact members are all located on the same plane parallel to the test plane 101; the projections of the contact ends 401 of multiple contact members on the test plane 101 along the height direction C of the frame are spaced apart; the shifting member 50 is movably disposed on the moving stage 30 along the length direction of the moving stage 30; multiple shifting members 50 are connected to the contact members 40 one by one; wherein, the shifting member 50 is used to change the distance of each contact member 40 to the first axis when the contact member 40 forms different angles with the test plane 101, so that the projection position of the contact end 401 of each contact member on the test plane 101 along the height direction C of the frame is the same as the projection position of the contact end 401 of each contact member on the test plane 101 along the height direction C of the frame when the contact member 40 forms different angles with the test plane 101.

[0029] It is understood that the frame 10 is a component used to form the test plane 101 and provide an installation position. The frame 10 can be constructed from multiple 4040 aluminum profiles or stainless steel pipes, but is not limited to these. Multiple displays 200 can be placed on the test plane 101 to form multiple workstations, allowing multiple displays 200 to be tested simultaneously. The display 200 to be tested is set on the frame 10, with its surface overlapping the test plane 101. During testing, the display 200 can be connected to a power source for power-on testing or tested without a power source. The display 200 can be fixed to the frame 10 with bolts, or clamps can be set on the frame 10 to hold the display 200, but is not limited to these methods.

[0030] The first drive device 20 is a component used to drive the moving platform 30 to move along the height direction C of the frame. For example, the first drive device 20 may include a motor and a scissor lift mechanism, with the motor driving the scissor lift mechanism for lifting. Alternatively, the first drive device 20 may use an electric push rod, a cylinder, a hydraulic lift, etc., but is not limited to these.

[0031] The moving stage 30 is an assembly used to carry the contact 40 and to position the contact 40 on the same plane. For example, the moving stage 30 may include two plates, one of which is parallel to the test plane 101 and is used to adjust the distance between the contact 40 and the test plane 101, and the other plate is rotatable to form an angle with the test plane 101 and is used to adjust the angle between the contact 40 and the test plane 101; or the moving stage 30 may include a plate that can move along the height direction C of the frame and can rotate about an axis parallel to the test plane 101, but is not limited thereto.

[0032] The contact 40 is a component used to apply test pressure to the surface of the display screen 200. The contact end 401 of the contact 401 is a part that abuts against the surface of the display screen 200. The contact end 401 of the contact 40 can be made of conductive rubber, silicone rubber, or hard alloy, but is not limited to these. The angle between the contact 40 and the test plane 101 is the angle between the direction of the force exerted by the contact 40 on the test plane 101 and the test plane 101. The contact element 40 can be movably mounted on the moving stage 30 along the height direction C of the frame. When the moving stage 30 moves to the point where the contact end 401 of the contact element abuts against the surface of the display screen 200, the moving stage 30 continues to move towards the test plane 101, so that the weight of the contact element 40 is fully applied to the display screen 200. The force exerted by the contact element 40 on the surface of the display screen 200 is determined by its own weight. Alternatively, the contact element 40 can be fixedly mounted on the moving stage 30, with the contact end 401 protruding from the side of the moving stage 30 facing the test plane 101. The force exerted by the contact element 40 on the surface of the display screen 200 is controlled by adjusting the height of the moving stage 30 through the first driving member 201, but is not limited to this. Multiple contact elements 40 can be distributed at intervals at multiple workstations according to a preset testing method to test the same position of the display screen 200 at multiple workstations respectively.

[0033] The shifting component 50 is an assembly used to move the contact 40 on the moving table 30 along the length direction of the moving table 30. The shifting component 50 may include multiple slides 501, and multiple slide grooves are formed on the moving table 30 along the length direction of the moving table 30. The slides 501 are movably arranged in the slide grooves one-to-one and along the length direction of the moving table 30. The contact 40 is disposed on the slides 501 and passes through the slide grooves. Alternatively, the shifting component 50 may include multiple telescopic rods, and multiple slide grooves are formed on the moving table 30 along the length direction of the moving table 30. The fixed end of the telescopic rod is disposed on the moving table 30, and the movable end of the telescopic rod is connected to the contact 40. The contact 40 passes through the slide grooves. However, it is not limited to these two methods.

[0034] In the existing technology, when performing multi-station testing, the existing display screen 200 testing device usually places the contact member 40 vertically in contact with the surface of the display screen 200 to improve the synchronization of multiple stations. However, in order to more realistically simulate the situation of a finger clicking on the display screen 200, when the test angle of the contact member 40 in contact with the surface of the display screen 200 is changed, the contact tip of the contact member 40 will be tilted, causing the position of the contact point to shift. The contact tip may not be able to contact the preset point, or multiple contacts may not be able to contact the surface of the display screen 200 at the same time, making it difficult to achieve synchronous testing of multiple stations. If each contact member 40 is repositioned and adjusted, the testing efficiency will be low.

[0035] The display screen touch press durability testing device 100 provided in this application adjusts the distance between the moving stage 30 and the test plane 101 through the first driving device 20. The moving stage 30 rotates to change the angle between the contact member 40 and the test plane 101. The shifting member 50 moves along the length direction of the moving stage 30 to change the projection position of the contact end 401 of the contact member on the test plane 101 along the height direction C of the frame. This ensures that when the moving stage 30 rotates to different angles, the projection position of the contact end 401 of the contact member on the test plane 101 along the height direction C of the frame is the same. This achieves that when the angle of the contact member 40 abutting against the display screen 200 is changed, the position of the contact end 401 abutting against the display screen 200 is the same. This effectively corrects the contact point offset caused by angle adjustment, enabling multiple stations to apply the same pressure synchronously. This improves the synchronicity of multiple stations of the display screen touch press durability testing device 100 at multiple test angles and enhances the accuracy of the test results.

[0036] In some embodiments, please refer to the following: Figures 1 to 4The moving stage 30 includes a lifting stage 301 and a tilting stage 302. The lifting stage 301 is mounted on the first driving device 20. The fixed end of the tilting stage 302 is hinged to one end of the lifting stage 301. The tilting stage 302 is located on the side of the lifting stage 301 away from the test plane 101. The tilting stage 302 has a tilting surface. The first axis is located at one end of the tilting stage 302. Contact members 40 are respectively inserted through the lifting stage 301 and the tilting stage 302. The contact end 401 of the contact member protrudes from the side of the lifting stage 301 facing the test plane 101. The contact member 40 is perpendicular to the tilting stage 302.

[0037] It can be understood that the lifting platform 301 is a component used to change the distance between the contact member 40 and the test plane 101 under the drive of the first driving device 20. The lifting platform 301 has a lifting plane parallel to the test plane 101. The lifting plane can be used to determine the distance between the contact member 40 and the test plane 101, and can also be used to make the contact ends 401 of the contact member lie on the same plane.

[0038] The tilting table 302 is a component used to change the angle between the contact 40 and the test plane 101. The short side of the tilting table 302 can be hinged to the short side of the lifting table 301. A ratchet can be provided at the hinge between the tilting table 302 and the moving table 30 to keep the tilting table 302 in a rotatable position. Rotating the tilting table 302 changes the angle between the tilting table 302 and the lifting table 301. Alternatively, the moving table 30 may also include a support rod. One end of the support rod is hinged to the side of the lifting table 301 facing the tilting table 302. The support rod can rotate about an axis parallel to the width direction of the tilting table 302. The other end of the support rod abuts against the side of the tilting table 302 facing the lifting table 301. By rotating the support rod, the angle between the tilting table 302 and the lifting table 301 can be changed, but this is not the only possible method.

[0039] With this configuration, the lifting platform 301 is positioned at one end of the first driving device 20, allowing it to move along the height direction C of the frame under the drive of the first driving device 20. The fixed end of the tilting platform 302 is hinged to one end of the lifting platform 301, enabling the tilting platform 302 to rotate and change the angle between the contact element 40 and the test plane 101. This allows the display screen touch press durability test device 100 to test the display screen 200 at multiple different angles, improving the matching degree between the test conditions and actual use, thereby effectively improving the reliability of the test results. Furthermore, the lifting platform 301 ensures that the contact ends 401 of the contact elements remain on the same plane after rotation, which helps maintain the synchronization of multiple contact elements 40, reduces the error of the test results, and improves the accuracy of the test results.

[0040] Optionally, the moving platform 30 further includes a second driving device 303, the fixed end of which is disposed at the other end of the lifting platform 301; the movable end of the second driving device 303 abuts against the movable end of the tilting platform 302; the movable end of the second driving device 303 can move along the height direction C of the frame; the second driving device 303 is used to change the size of the angle formed between the lifting platform 301 and the tilting platform.

[0041] It is understood that the second drive device 303 is a component used to move the movable end of the tilting table 302 to make the tilting table 302 rotate about the hinge. The second drive device 303 may include a cylinder and a roller. One end of the cylinder is located on the side of the lifting platform 301 facing the tilting table 302, and the roller is located on the other end of the cylinder. The roller abuts against the side of the tilting table 302 facing the lifting platform 301. By driving the cylinder to rise and fall, the tilting table 302 is rotated. Alternatively, the second drive device 303 may include an electric telescopic rod. One end of the electric telescopic rod is located on the side of the lifting platform 301 facing the tilting table 302, and the other end of the electric telescopic rod abuts against the side of the tilting table 302 facing the lifting platform 301. By driving the electric telescopic rod to rise and fall, the tilting table 302 is rotated. However, it is not limited to this.

[0042] With this configuration, the fixed end of the second drive device 303 is located at the other end of the lifting platform 301, and the movable end of the second drive device 303 abuts against the movable end of the tilting platform 302. By moving the movable end of the second drive device 303 along the height direction C of the frame, the angle formed between the lifting platform 301 and the tilting platform is changed, thereby changing the angle between the contact element 40 and the test plane 101. By driving the tilting platform 302 to rotate through a single second drive device 303, the angle of the contact element 40 is changed uniformly. This helps to maintain the synchronization of multiple contact elements 40, reduces the difficulty of controlling and adjusting the display screen touch press durability test device 100, and thus reduces the difficulty and cost of maintaining the display screen touch press durability test device 100.

[0043] In some embodiments, please refer to Figures 1 to 4 The flipping table 302 has multiple first slide grooves 3021; ​​the length direction of the first slide grooves 3021 is parallel to the length direction of the flipping table 302; the multiple first slide grooves 3021 are spaced apart; the contact member 40 passes through the first slide groove 3021; ​​the shifting member 50 includes multiple slide tables 501, which are correspondingly arranged in the first slide grooves 3021; ​​the slide tables 501 can move in the first slide grooves 3021 along the length direction of the flipping table 302; wherein, the contact members 40 are correspondingly arranged in the slide tables 501; the slide tables 501 are used to move along the length direction of the flipping table 302 when the flipping table surface and the test plane 101 are at an angle, so as to adjust the projection position of the contact end 401 of the contact member on the test plane 101 along the height direction C of the frame.

[0044] It can be understood that the first slide 3021 is a structure that runs through the tilting table 302, and the long side of the first slide 3021 is parallel to the length direction of the tilting table 302.

[0045] The slide table 501 is a component used to move within the first slide groove 3021 to change the position of the contact member 40. It can have a moving groove along the length of the tilting table 302, or a track can be provided on the inner wall of the first slide groove 3021. A protruding structure is provided on the side of the slide table 501, which can enter the moving groove or be placed on the track, allowing the slide table 501 to move along the length of the tilting table 302, but is not limited to these methods. The contact member 40 can pass through the slide table 501, or can be connected to the side of the slide table 501, but is not limited to these methods.

[0046] With this configuration, multiple first slide grooves 3021 are opened on the tilting table 302. The length direction of the first slide grooves 3021 is parallel to the length direction of the tilting table 302. The slide table 501 is movably set in the first slide grooves 3021 along the length direction of the tilting table 302. When the tilting table 302 rotates, the slider can move along the length direction of the tilting table 302, which compensates for the offset of the contact end 401 of the contact element due to rotation. This keeps the projection position of the contact end 401 of the contact element on the test plane 101 along the height direction C of the frame in the same position, effectively improving the synchronization of multiple contact elements 40, improving the accuracy and reliability of the test results, and eliminating the need for a complex electronic control system. This enhances the automation and adaptability of the display screen touch press durability test device 100.

[0047] Optionally, the lengths of the multiple first slide grooves 3021 can be different. The length of the multiple first slide grooves 3021 increases as the distance from the inner wall of the fixed end away from the tilting table 302 to the fixed end of the tilting table 302 increases. The first slide groove 3021 is used to make the side wall of the slide 501 away from the fixed end of the tilting table 302 fit against the inner wall of the first slide groove 3021 away from the fixed end of the tilting table 302 when the tilting table 302 is parallel to the initial position of the lifting table 301, and the contact end 401 of the contact member is located at the first point. When the tilting table 302 rotates to a preset angle with the lifting table 301, the slide 501 moves to make the side wall of the slide 501 near the fixed end of the tilting table 302 fit against the inner wall of the first slide groove 3021 near the fixed end of the tilting table 302, and the contact end 401 of the contact member is located at the first point.

[0048] This configuration limits the movement distance of the slide table 501 by the length of the first slide groove 3021, ensuring that the position of the contact end 401 of the contact element is the same as when the tilting table 302 is in its initial position, at least when the angle between the tilting table 302 and the lifting table 301 is a preset angle. This effectively improves the synchronization of multiple contact elements 40, enhances the accuracy and reliability of the test results, and eliminates the need for a complex electronic control system, thereby increasing the automation and adaptability of the display screen touch press durability test device 100.

[0049] In some embodiments, please refer to Figures 1 to 4 The shifting component 50 also includes multiple linear bearings 502, which are arranged one-to-one on the slide table 501; the axis of the linear bearing 502 is perpendicular to the flip table surface; the contact element 40 passes through the linear bearing 502.

[0050] It is understood that the linear bearing 502 is a component used to enable the contact line to move in a direction perpendicular to the tilting table surface. The linear bearing 502 may pass through the slide table 501 in a direction perpendicular to the tilting table surface, or it may be disposed on the side of the slide table 501 in a direction perpendicular to the tilting table surface, but is not limited thereto. Optionally, in some embodiments, the linear bearing 502 may be replaced by a guide sleeve, but is not limited thereto.

[0051] This configuration places the linear bearing 502 on the slide 501 with its axis perpendicular to the tilting table surface. The contact element 40 passes through the linear bearing 502, allowing it to move in a direction perpendicular to the tilting table surface. During the rotation of the tilting table 302, the contact element 40 can be moved in this direction, ensuring that the contact ends 401 of the contact element are on the same plane parallel to the test plane 101. This improves the accuracy of the contact element 40's movement in the direction perpendicular to the tilting table surface, reduces friction and wear, increases the sensitivity of the contact element 40's movement, extends its service life, facilitates the disassembly and assembly of the contact element 40, simplifies the maintenance of the display screen touch-press durability test device 100, and improves the accuracy of the results under multi-angle and multi-cycle test conditions.

[0052] In some embodiments, please refer to Figures 1 to 4The shifting component 50 also includes multiple elastic elements 503, which are arranged one-to-one in multiple first slide grooves 3021. The fixed end of the elastic element 503 is connected to the flip table 302. The movable end of the elastic element 503 is connected one-to-one to the slide table 501. The elastic element 503 is used to limit the slide table 501 from moving toward the fixed end of the flip table 302 along the length direction of the flip table 302. The elastic force of the multiple elastic elements 503 decreases as the distance from the fixed end of the elastic element 503 to the fixed end of the flip table 302 increases. The elastic element 503 is used to make the slide table 501 move different distances toward the fixed end of the flip table 302 when the angle between the flip table surface and the test plane 101 is different, so that the projection position of the contact end 401 of the contact element on the test plane 101 along the height direction C of the frame is the same.

[0053] It is understood that the elastic element 503 is a component used to limit the movement of the slide 501 toward the fixed end of the tilting table 302 based on the angle between the tilting table 302 and the lifting table 301. For example, the elastic element 503 can be a helical spring or a gas spring, and a tension spring or a compression spring can be selected according to the installation position, but it is not limited to these.

[0054] When the rotating platform rotates to form an angle with the test plane 101, the offset distance of the contact ends 401 of the multiple contact elements along the length direction A of the frame increases as the distance from the contact element 40 to the fixed end of the rotating platform 302 increases. Therefore, the elastic coefficient of the multiple elastic elements 503 decreases as the distance from the fixed end of the elastic element 503 to the fixed end of the rotating platform 302 increases, thereby causing the distance the contact element 40 moves along the length direction of the rotating platform 302 to increase as the distance from the contact element 40 to the fixed end of the rotating platform 302 increases.

[0055] In this configuration, multiple elastic elements 503 are correspondingly placed in multiple first slide grooves 3021. The elastic force of the multiple elastic elements 503 decreases as the distance from the fixed end of the elastic element 503 to the fixed end of the tilting table 302 increases. As a result, the distance that the contact element 40 moves along the length direction of the tilting table 302 increases as the distance from the contact element 40 to the fixed end of the tilting table 302 increases. This forms a dynamic compensation for the offset of the contact end 401 of the contact element along the length direction A of the frame caused by the rotation of the tilting table 302. This reduces the test deviation caused by the change in the rotation angle of the tilting table surface, effectively improves the synchronization and consistency of the tests at multiple stations, and thus effectively improves the accuracy of the tests.

[0056] In some embodiments, please refer to Figures 1 to 5The contact element 40 includes a connecting rod 402 and a load 403. The connecting rod 402 passes through the moving stage 30. The contact end of the connecting rod 402 near the test plane 101 protrudes from the side of the moving stage 30 facing the test plane 101. The load 403 is detachably connected to the end of the connecting rod 402 away from the test plane 101.

[0057] It is understood that the connecting rod 402 is a rod-shaped component used to transmit mechanical loads. The connecting rod 402 can be made of stainless steel or carbon fiber, but is not limited to these materials. The end of the connecting rod 402 facing the test plane 101 is the contact end. The contact end of the connecting rod 402 can be wrapped with conductive rubber or silicone rubber, and it can contact the display screen 200 through the conductive rubber or silicone rubber, or it can directly contact the display screen 200, but is not limited to these methods. The connecting rod 402 passes through the tilting platform 302 and the lifting platform 301, and the contact end of the connecting rod 402 protrudes from the side of the lifting platform 301 facing the test plane 101, while the other end of the connecting rod 402 protrudes from the side of the tilting platform 302 away from the lifting platform 301.

[0058] The load 403 is a component used to adjust the contact pressure acting on the surface of the display screen 200. The load 403 can be threaded to the end of the connecting rod 402 away from the test plane 101, or a groove can be formed at one end of the load 403, the diameter of which is greater than or equal to the diameter of the connecting rod 402, allowing the load 403 to be fitted onto the end of the connecting rod 402 away from the test plane 101. However, this is not a limitation. The load 403 can be configured with different weight specifications depending on the test conditions, such as 100g, 200g, or 500g, but is not limited to these. Loads 403 located in different workstations can be different, and loads 403 located in the same workstation can be the same, but is not limited to these.

[0059] With this configuration, the connecting rod 402 is inserted through the moving stage 30, with the contact end of the connecting rod 402 protruding from the side of the moving stage 30 facing the test plane 101. The contact end of the connecting rod 402 abuts against the surface of the display screen 200 as the moving stage 30 moves along the height direction C of the frame. The load 403 is detachably set at the end of the connecting rod 402 away from the test plane 101. This allows for quick replacement of the load 403 without affecting the position of the contact end of the connecting rod 402, eliminating the need for recalibration. While maintaining the synchronization of multi-station testing, this improves the flexibility and applicability of the display screen touch press durability testing device 100.

[0060] In some embodiments, please refer to Figures 1 to 5 The contact element 40 also includes a height-fixing element 404, which is disposed on the connecting rod 402. The height-fixing element 404 is located between the contact end of the connecting rod 402 and the load 403. The height-fixing element 404 abuts against the side of the lifting platform 301 away from the test plane 101.

[0061] It can be understood that the height-fixing component 404 is a part used to limit the length of the contact end of the connecting rod 402 protruding from the lifting platform 301 within a preset range. That is, the height-fixing component 404 is used to ensure that the vertical distance from the contact end of each connecting rod 402 to the test plane 101 is equal. The height-fixing component 404 can be a sphere, a rod with its axis perpendicular to the connecting rod 402, or a nut. By threading a thread into the connecting rod 402, the nut can be fitted onto the connecting rod 402. The length of the contact end of the connecting rod 402 protruding from the lifting platform 301 can be adjusted by rotating the nut, but it is not limited to these. The side of the height-fixing component 404 facing the test plane 101 abuts against the side of the lifting platform 301 away from the test plane 101.

[0062] With this configuration, the height-fixing component 404 is placed on the connecting rod 402, positioned between the contact end of the connecting rod 402 and the load 403. The height-fixing component 404 abuts against the side of the lifting platform 301 away from the test plane 101, ensuring that the vertical distance from the contact end of each connecting rod 402 to the test plane 101 is equal. Through the mechanical limiting of the positioning component, no manual adjustment is required, which improves the efficiency of use and maintenance of the display screen touch press durability test device 100, and helps to improve the synchronization of multiple contact components 40, thereby improving the accuracy of the test results of the display screen touch press durability test device 100.

[0063] In some embodiments, please refer to Figures 1 to 4 The lifting platform 301 has multiple second slide grooves 3011 along its own length direction; the contact element 40 is correspondingly inserted into the second slide groove 3011.

[0064] It is understood that the second slide 3011 is a component used to provide space for the contact member 40 to move along the length of the lifting platform 301. The second slide 3011 extends through the lifting platform 301 along the height direction of the lifting platform 301. The width of the second slide 3011 is equal to the diameter of the contact member 40 and smaller than the width of the height-fixing member 404.

[0065] With this configuration, multiple second slides 3011 are provided on the lifting platform 301. The long side of the second slide 3011 is parallel to the length direction of the lifting platform 301. The contact elements 40 are correspondingly inserted into the second slides 3011. The contact ends 401 of the contact elements move along the length direction of the lifting platform 301 through the second slides 3011, preventing the contact elements 40 from deflecting due to test pressure. This allows the contact ends 401 of the contact elements to move stably along a predetermined trajectory, which helps to improve the consistency and synchronization of the contact elements 40 in multiple stations, thereby improving the accuracy of the multi-station test data.

[0066] In some embodiments, please refer to Figures 1 to 4The first driving device 20 includes a first driving member 201 and two forks 202. The first driving member 201 is mounted on the frame 10. The two forks 202 are arranged opposite to each other and spaced apart on both sides of the frame 10 in the width direction. One end of the fork 202 is mounted on the frame 10. The other end of the fork 202 is mounted on the side of the moving stage 30 facing the test plane 101. The forks 202 are connected to the power output end of the first driving member 201. The forks 202 are used to change the distance between the moving stage 30 and the test plane 101 under the drive of the first driving member 201.

[0067] It can be understood that the first drive member 201 is a device for providing driving force along the length direction A of the frame, and the first drive member 201 is located on the side of the test plane 101 away from the lifting platform 301. The first driving component 201 may include a drive motor, a worm gear, a nut, a slider, and a connecting rod. The drive motor is mounted on the frame 10, the worm gear is connected to the power output end of the drive motor, and the worm gear is positioned along the length direction A of the frame. The nut is movably mounted on the worm gear, the slider is mounted on the nut, and the connecting rod passes through the slider along the width direction B of the frame. The two ends of the connecting rod are respectively connected to the ends of the two fork arms 202. The drive motor drives the worm gear to rotate, thereby causing the nut, slider, and connecting rod to move along the length direction A of the frame, driving the fork arms 202 to raise or lower the moving platform 30. Alternatively, the first driving component 201 may include a cylinder and a connecting rod. The cylinder is positioned on the frame 10 along the length direction A of the frame, and the connecting rod is positioned at the movable end of the cylinder along the width direction B of the frame. The two ends of the connecting rod are respectively connected to the ends of the two fork arms 202. The cylinder can extend and retract to move the connecting rod along the length direction A of the frame, thereby causing the fork arms 202 to raise or lower the moving platform 30, but is not limited to this.

[0068] The fork arm 202 is a device that converts the movement along the length direction A of the frame into the movement along the height direction C of the frame. The fork arm 202 may include one or more sets of connecting rods connected end to end. The fork arm 202 is driven to unfold or retract by the first driving member 201 to control the lifting and lowering of the moving table 30.

[0069] With this configuration, the first drive unit 201 is mounted on the frame 10, and two fork arms 202 are positioned opposite each other and spaced apart on both sides of the frame 10 in the width direction. One end of each fork arm 202 is mounted on the frame 10, and the other end is mounted on the side of the moving stage 30 facing the test plane 101. The fork arms 202 are connected to the power output end of the first drive unit 201. The first drive unit 201 simultaneously drives the two fork arms 202 to expand and contract. A single drive source drives the two fork arms 202 to move synchronously, which helps to improve the stability of the display screen touch press durability test device 100, reduce errors caused by movement during the test, and effectively improve the accuracy and reliability of the test data.

[0070] In some embodiments, please refer to Figures 1 to 4 The fork arm 202 includes an active arm 2021 and a driven arm 2022. The movable end of the active arm 2021 is movably disposed on the frame 10 along the length direction A of the frame. The fixed end of the active arm 2021 is disposed on the side of the moving stage 30 facing the test plane 101. The movable end of the active arm 2021 is connected to the power output end of the first drive member 201. The movable end of the driven arm 2022 is movably disposed on the side of the moving stage 30 facing the test plane 101 along the length direction A of the frame. The fixed end of the driven arm 2022 is disposed on the frame 10. The length of the active arm 2021 is equal to the length of the driven arm 2022.

[0071] It can be understood that the active arm 2021 is a rod connected to the first drive device 20, and the driven arm 2022 is a rod hinged to the active arm 2021. The hinge point between the active arm 2021 and the driven arm 2022 is located at the midpoint between the two ends of the active arm 2021, and also at the midpoint between the two ends of the driven arm 2022. The active arm 2021 can be a round rod, a square rod, or a long strip plate structure, but is not limited to these. The driven arm 2022 has the same shape as the active arm 2021.

[0072] With this configuration, the movable end of the active arm 2021 is movably mounted on the frame 10 along the length direction A of the frame. The fixed end of the active arm 2021 is located on the side of the moving stage 30 facing the test plane 101. The movable end of the active arm 2021 is connected to the power output end of the first drive unit 201. The movable end of the driven arm 2022 is movably mounted on the side of the moving stage 30 facing the test plane 101 along the length direction A of the frame. The fixed end of the driven arm 2022 is located on the frame 10. The first drive unit 20 drives the movable end of the active arm 2021 along... The frame moves along the length direction A, causing the movable end of the driven arm 2022 to move along the length direction A of the frame, thereby driving the moving stage 30 to rise or fall, causing the contact element 40 to move toward or away from the test plane 101. The length of the driving arm 2021 is equal to the length of the driven arm 2022, which helps to keep the moving stage 30 parallel to the test plane 101, improves the accuracy of the synchronous lifting and lowering of multiple contact elements 40, improves the synchronization degree of multiple contact elements 40 contacting the surface of the display screen 200, and significantly improves the synchronization accuracy of multi-station testing and the consistency of test results.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
