Description

Technical Field

[0001] The present invention belongs to the field of detection technology, and particularly relates to a mobile phone screen toughness detection device. Background Art

[0002] Traditional mobile phone screens are mostly made of rigid materials such as glass or hard plastics. The toughness evaluation of such screens is mainly completed through hardness tests, impact tests, and bending tests. However, with the development and popularization of curved screens, flexible screens, and foldable screen technologies, new problems have emerged for the detection methods and devices for these new display technologies.

[0003] Firstly, traditional toughness detection devices are mainly designed based on flat screens. When performing bending tests, the direction of the applied force is usually fixed. This means that when applied to the testing of curved screens with complex bending characteristics, the effectiveness of traditional devices is significantly limited. Given that curved screens have various different bending radii and specifications, traditional testing devices lacking flexibility are difficult to adjust the direction and magnitude of the applied force according to the unique characteristics of each curved screen, thus unable to comprehensively and accurately evaluate all types of curved screens.

[0004] Furthermore, although the single-direction force in traditional bending tests is suitable for evaluating the bending resistance of flat screen materials, for curved screens with different bending radii and shapes, this testing method is insufficient. The designs of curved screens range from slightly curved to fully wrapped forms, and each design requires specific bending test conditions to accurately reflect its durability and reliability. If the testing device cannot flexibly adjust the direction and position of the applied force, it cannot accurately simulate the various stress situations that a curved screen may encounter during actual use. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a mobile phone screen toughness detection device to solve the problems existing in the above background art.

[0006] To solve the above technical problems, a technical solution of the present invention is a mobile phone screen toughness detection device, including a detection platform and a fixture for fixing the screen, and a control arm. The two ends of the control arm are respectively a swing end and an output end. The swing end of the control arm is rotatably installed on the detection platform, and the output end of the control arm is connected to the fixture; by the directional movement of the output end of the control arm to drive the fixture, the directional bending toughness detection of the screen is realized; by the rotation of the swing end of the control arm on the detection platform to change the orientation of the output end of the control arm, the bending toughness detection of the screen in different directions is thus realized.

[0007] Preferably, the control arm includes a guiding structure, and the output direction of the output component is changed by the swing of the guiding structure on the detection platform to realize the control of the orientation of the output end of the control arm; an output component, which can convert rotational motion into linear motion, and the output component is composed of a rotating part and a sliding part, the sliding part is arranged on the guiding structure, and the sliding part is connected to the fixture.

By switching the docking part between the first driving port and the second driving port, the switching between the swing of the control arm and the directional movement of the output end of the control arm is realized; when the docking part is connected to the first driving port, the driving motor controls the swing of the control arm; when the docking part is connected to the second driving port, the driving motor controls the directional movement of the output end of the control arm.

[0009] Furthermore, a control component is arranged between the detection platform and the swing arm, and the control component is composed of a guide rail and a mounting block.

[0010] Furthermore, a clamping component is arranged between the guiding structure and the detection platform, and the clamping component is used to fixedly connect the guiding structure and the detection platform to ensure that the orientation of the output end of the control arm remains unchanged when performing the directional bending toughness test on the screen; the clamping component can be switched between a clamping state and a loosening state, and the clamping component is composed of a clamping block and a spring; the clamping block is arranged on the first driving port and can be pushed by the docking part to make the clamping component enter the loosening state; the spring is used to control the clamping component to enter the clamping state to avoid unnecessary movement; when the docking part is connected to the first driving port, the clamping component is in the loosening state.

[0011] Further, the output component is a crank-slider mechanism, the rotating member is a rotating disk, the sliding member is a sliding block, a connecting rod is arranged between the rotating disk and the sliding block, and the rotating disk, the sliding block and the connecting rod are hinged; when the output component is a crank-slider mechanism, driving the rotating member to rotate can enable the control arm to perform a directional reciprocating bending toughness test on the screen.

[0012] Further, the output component is a gear-rack mechanism, the rotating member is a rotating gear, the sliding member is a sliding rack, and the rotating gear and the sliding rack are meshed; when the output component is a gear-rack mechanism, driving the rotating member to rotate can enable the control arm to perform a directional large-stroke bending toughness test on the screen.

[0013] To solve the above technical problems, the second technical solution of the present invention is a usage method of the mobile phone screen toughness detection device described in the first technical solution, and the usage method includes the following steps:

[0014] S1. Position adjustment of the swing arm on the detection platform: Switch the docking member to the third drive port, and through the drive system composed of the driving member and the transmission shaft, cooperate with the roller to drive the control arm to move along the guide rail, and complete the position adjustment of the swing arm on the detection platform to meet the detection requirements for screens of different sizes and specifications;

[0015] S2. Determination of the bending direction: Switch the docking member to the first drive port, and change the orientation of the output end of the control arm by rotating the swing end of the control arm on the detection platform, so as to select the bending toughness of different directions of the screen for detection;

[0018] To solve the above technical problems, the third technical solution of the present invention is a usage method of the mobile phone screen toughness detection device when the output component adopts a crank-slider mechanism in the first technical solution, and the usage method includes the following steps: As the rotating disk rotates, the connecting rod drives the sliding block to perform a directional reciprocating movement along the direction of the guiding structure, simulating the bending force applied to the mobile phone screen, and the mobile phone screen will be repeatedly bent during the process.

[0019] To solve the above technical problems, the fourth technical solution of the present invention is a method for using the mobile phone screen toughness detection device when the output component in the first technical solution adopts a rack and pinion mechanism. The method includes the following steps: As the rotating gear rotates, due to the meshing connection between the rotating gear and the sliding rack, the sliding rack will move directionally along the direction of the guiding structure, simulating the bending force applied to the mobile phone screen. During the process, a directional large-stroke bending force will be applied to the mobile phone screen; when the rotating gear rotates in reverse, the bending force applied to the mobile phone screen will be cancelled.

[0020] The technical effects of the present invention are mainly reflected in the following aspects:

[0021] The present invention integrates multiple driving modes and an automatic switching mechanism, such as the switching of the docking component between different driving ports, realizing highly automated device operation; users can quickly switch different operation modes according to specific test requirements without manual intervention, which not only improves work efficiency but also simplifies the operation process and reduces the possibility of human errors.

[0022] Traditional detection devices are limited by the single-direction bending force application method and are difficult to meet the detection requirements of complex-shaped screens such as curved screens. Through the rotational design of the swinging end of the control arm on the detection platform, the present invention can flexibly adjust the direction of the output end of the control arm, thereby realizing accurate bending toughness testing for screens with different directions and curvatures; enabling the device to simulate various stress conditions in actual use and significantly improving the accuracy and reliability of test results.

[0023] Considering the diversity of curved screen, flexible screen, and foldable screen designs, ranging from slight arcs to fully wrapped forms, the present invention allows for adjusting the direction and magnitude of the bending force according to the unique characteristics of each screen through the combined design of the guiding structure and the output component; not only improving the flexibility of the test process but also ensuring a comprehensive evaluation of different types of screen materials and meeting the growing demand for diverse display technologies in the market.

[0024] By using a crank-slider or rack and pinion mechanism as the output component, the present invention can efficiently convert rotational motion into linear motion and apply a force with a specific direction and magnitude to the screen; this directional bending can not only simulate bending in the plane but also include complex spatial curve bending, helping to more comprehensively understand the toughness and durability of the screen material; especially when using a rack and pinion mechanism, it can also achieve large-stroke bending tests, greatly expanding the application range of the device.

[0034] Embodiment 1

[0035] Refer to Figure 1, this embodiment discloses a mobile phone screen toughness detection device, including a detection platform 1 and a fixture 2 for fixing the screen, and a control arm 3. The two ends of the control arm 3 are respectively a swing end and an output end. The swing end of the control arm 3 is rotatably installed on the detection platform 1, and the output end of the control arm 3 is connected to the fixture 2; the fixture 2 is driven by the directional movement of the output end of the control arm 3 to realize the directional bending toughness detection of the screen; the orientation of the output end of the control arm 3 is changed by the rotation of the swing end of the control arm 3 on the detection platform 1, so as to realize the bending toughness detection of the screen in different directions.

[0036] The advantages of the toughness detection device in this embodiment: Traditional toughness detection devices can only provide bending force in a single direction, while the present invention allows the output end of the control arm 3 to move in multiple directions, which benefits from the rotational design of the swing end of the control arm 3 on the detection platform 1; this enables the present invention to adjust the direction of the bending force for curved screens with different curvatures and shapes, thereby more accurately simulating the stress conditions in actual use. Since the designs of curved screens vary widely, from slightly curved to fully wrapped forms, the present invention can meet the design requirements of various different screens by flexibly adjusting the control arm 3; at the same time, by using the directional movement of the output end of the control arm 3, a force with a specific direction and magnitude can be applied to the screen, and then the bending resistance performance of the screen under these specific conditions can be evaluated. This directional bending is not limited to simple in-plane bending, but also includes complex spatial curve bending, which helps to comprehensively understand the toughness and durability of the screen material.

[0037] See Figures 2 to 5 , the control arm 3 includes a guiding structure 31. The output direction of the output component 32 is changed by the swing of the guiding structure 31 on the detection platform 1 to realize the control of the orientation of the output end of the control arm 3; a first driving port 311 is provided at the connection between the guiding structure 31 and the detection platform 1, and the first driving port 311 is used to drive the guiding structure 31 to swing; an output component 32, the output component 32 can convert rotational motion into linear motion. The output component 32 is composed of a rotating member 321 and a sliding member. The sliding member is arranged on the guiding structure 31, and the sliding member is connected to the fixture 2. A second driving port 322 for driving the rotation of the rotating member 321 is provided on the rotating member 321; the first driving port 311 and the second driving port 322 are coaxially arranged; the control arm 3 is provided with a driving shaft, and a docking member 34 is slidably arranged on the driving shaft. By switching the docking member 34 between the first driving port 311 and the second driving port 322, the switching between the swing of the control arm 3 and the directional movement of the output end of the control arm 3 is realized;

[0038] See Figures 2 to 5, when it is necessary to adjust the orientation of the output end of the control arm 3, the transmission shaft 33 of the driving motor will align and connect the docking member 34 to the first driving port 311. At this time, the operation of the driving motor will cause the guiding structure 31 to swing around its axis, thereby changing the direction of the output end of the control arm 3 to meet the requirements of curved screens of different shapes. When it is necessary to apply a bending force in a specific direction to the screen, the driving motor will switch the docking member 34 to the second driving port 322. In this way, the energy of the driving motor is transmitted to the rotating member 321, causing it to rotate. The rotational motion of the rotating member 321 is mechanically converted into a linear motion of the sliding member, and finally drives the fixture 2 to move in a predetermined direction to perform an accurate bending toughness test on the screen. It not only realizes the effective test of traditional flat screens, but also can flexibly cope with curved screens, flexible screens and folding screens of various complex shapes.

[0039] See Figures 2 to 5 , a control component 36 is arranged between the detection platform 1 and the swing arm. The control component 36 is composed of a guide rail 361 and a mounting block 362. A roller 363 is arranged on the mounting block 362. The mounting block 362 is slidably arranged on the guide rail 361 and is driven by the roller 363; the swing arm is rotatably arranged on the mounting block 362, and a connecting shaft is arranged between the swing arm and the mounting block 362; a transmission shaft 33 and a driving member 364 that are coaxially driven with itself are arranged on the roller 363. The transmission shaft 33 passes through the connecting shaft and is coaxially arranged with the connecting shaft. The driving member 364 has a third driving port 365, and the third driving port 365 is coaxially arranged with the second driving port 322; when the docking member 34 is connected to the third driving port 365, the driving motor controls the control arm 3 to move on the guide rail 361.

[0040] Specifically, when adjusting the swing direction of the control arm 3, the docking member 34 is connected to the first driving port 311; for directional bending toughness detection, the docking member 34 is connected to the second driving port 322; and when it is necessary to adjust the overall position of the control arm 3, the docking member 34 is connected to the third driving port 365.

[0041] See Figures 3 to 5, a clamping member 35 is provided between the guiding structure 31 and the detection platform 1. The clamping member 35 is used to fixedly connect the guiding structure 31 and the detection platform 1 to ensure that when performing the directional bending toughness test on the screen, the orientation of the output end of the control arm 3 remains unchanged; the clamping member 35 can be switched between a clamped state and a released state, and the clamping member 35 is composed of a clamping block 351 and a spring; the clamping block 351 is arranged on the first driving port 311 and can be pushed by the docking member 34, so that the clamping member 35 enters the released state; the clamping block 351 is located on the first driving port 311 and can be pushed into the released state by the docking member 34, so that the guiding structure 31 can swing freely; and under the action of no external force, the spring will urge the clamping block 351 to enter the clamped state to prevent unnecessary movement. The spring is used to control the clamping member 35 to enter the clamped state to avoid unnecessary movement; when the docking member 34 is connected to the first driving port 311, the clamping member 35 is in the released state.

[0042] When it is necessary to adjust the orientation of the output end of the control arm 3, the docking member 34 is first connected to the first driving port 311. At this time, the clamping member 35 is pushed to the released state, allowing the guiding structure 31 to swing relative to the detection platform 1, thereby changing the direction of the output end of the control arm 3; after the direction adjustment is completed, the docking member 34 leaves the first driving port 311, and the clamping member 35 automatically returns to the clamped state under the action of the spring, firmly fixing the guiding structure 31 on the detection platform 1 to avoid displacement during the test. When performing the directional bending toughness test on the screen, the docking member 34 needs to be switched to the second driving port 322 to make the rotating member 321 start to rotate and drive the sliding member to move linearly.

[0043] See Figure 6 , the output member 32 is a crank-slider mechanism 4, the rotating member 321 is a rotating disk 41, the sliding member is a sliding block 42, a connecting rod 43 is arranged between the rotating disk 41 and the sliding block 42, and the rotating disk 41, the sliding block 42 and the connecting rod 43 are hinged; when the output member 32 is a crank-slider mechanism 4, driving the rotating member 321 to rotate can enable the control arm 3 to perform a directional reciprocating bending toughness test on the screen.

[0044] Specifically, when the drive motor is connected to the second drive port 322 through the docking member 34 and starts to work, it drives the rotating disk 41 to rotate; the rotation of the rotating disk 41 is transmitted to the slider 42 through the connecting rod 43, causing the slider 42 to perform a linear reciprocating motion in a specific direction. Since the slider 42 is directly connected to the fixture 2, this linear reciprocating motion can apply a directional bending force to the screen, simulating the stress conditions in actual use. By controlling the rotation speed of the rotating disk 41, the moving distance and frequency of the slider 42 can be precisely adjusted, thereby performing bending tests on the screen with different intensities and frequencies; it is suitable for evaluating the durability and reliability of flexible screen or foldable screen materials because it can simulate various bending situations that these screens may encounter during actual use.

[0045] See Figure 7 , the output member 32 is a rack and pinion mechanism 5, the rotating member 321 is a rotating gear 51, the sliding member is a sliding rack 52, and the rotating gear 51 and the sliding rack 52 are meshed; when the output member 32 is a rack and pinion mechanism 5, driving the rotating member 321 to rotate can enable the control arm 3 to perform a directional large-stroke bending toughness test on the screen.

[0046] Specifically, when the drive motor is connected to the second drive port 322 through the docking member 34 and starts to work, it drives the rotating gear 51 to rotate; the rotation of the rotating gear 51 meshes with the sliding rack 52, causing the sliding rack 52 to perform a linear motion in a specific direction. Since the sliding rack 52 is directly connected to the fixture 2, this linear motion can apply a large-stroke bending force to the screen, simulating the stress conditions in actual use. By controlling the number of rotations and speed of the rotating gear 51, the moving distance and frequency of the sliding rack 52 can be precisely adjusted, thereby performing bending tests on the screen with different intensities and strokes; it is suitable for flexible screen or foldable screen materials that require large-stroke bending tests because it can provide a larger bending angle and a longer bending path to comprehensively evaluate the durability and reliability of the screen material.

[0050] S2. Determination of bending direction: Switch the docking part 34 to the first drive port 311, and change the orientation of the output end of the control arm 3 by rotating the swinging end of the control arm 3 on the detection platform 1, so as to select the bending toughness of the screen in different directions for detection;

[0051] S3. Directional bending test: Switch the docking part 34 to the second drive port 322, start the drive motor to make the output end of the control arm 3 move directionally, and then drive the fixture 2 to realize the detection of the directional bending toughness of the screen;

[0052] S4. Multi-directional bending test: If it is necessary to test different directions of the screen, repeat S2 and S3, and conduct a new bending test each time after adjusting the direction.

[0053] Embodiment III

[0054] This embodiment discloses a method for using the mobile phone screen toughness detection device when the output component 32 in Embodiment I adopts the crank-slider mechanism 4. The method includes the following steps:

[0055] When the crank-slider mechanism 4 is adopted, as the rotating disk 41 rotates, the connecting rod 43 drives the sliding block 42 to perform a directional reciprocating motion along the direction of the guiding structure 31, simulating the bending force applied to the mobile phone screen, and the mobile phone screen will be bent repeatedly during the process. This method is particularly suitable for simulating various dynamic stress situations that the screen may experience in actual use.

[0056] Embodiment IV

[0057] This embodiment discloses a method for using the mobile phone screen toughness detection device when the output component 32 in Embodiment I adopts the gear-rack mechanism 5. The method includes the following steps:

[0058] When the gear-rack mechanism 5 is used as the output component 32, as the rotating gear 51 rotates, due to the meshing connection between the rotating gear 51 and the sliding rack 52, the sliding rack 52 will move directionally along the direction of the guiding structure 31, simulating the bending force applied to the mobile phone screen, and a directional large-stroke bending force will be applied to the mobile phone screen during the process; when the rotating gear 51 rotates in reverse, the bending force applied to the mobile phone screen is cancelled. This method is applicable to situations where large-range bending tests are required, and can comprehensively evaluate the durability and reliability of flexible screens or folding screens.

[0059] In addition; as common knowledge in this industry; for the gear-rack mechanism 5 and the crank-slider mechanism 4 mentioned above, the drive shaft is provided with an independent drive motor. The above is common knowledge; therefore, the principle and structure thereof will not be described in detail.

[0060] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
