[0002] A touchscreen, also known as a touch panel, is a sensor-based liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the haptic feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display. During its manufacturing process, a flatness inspection process is required. Current testing methods typically use manual methods, but this method suffers from poor accuracy and low efficiency due to the touchscreen's tendency to shake during inspection.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0016] Example

[0017] To address the aforementioned technical problems, this embodiment provides a device for detecting the flatness of a touchscreen, such as... Figure 1 As shown, the device includes a worktable 10, a limiting groove 11 for accommodating a touchscreen, limiting components 20 on both sides of the limiting groove 11, a pressing detection component 30 at the top of the worktable 10, and a first detection probe 12 within the limiting groove 11. By providing the limiting groove 11 and the limiting components 20 on both sides, the touchscreen can be positioned within the limiting groove 11 by the limiting components 20. Furthermore, the pressing detection component 30 at the top of the worktable 10 and the first detection probes 12 within the limiting groove 11 allow for the determination of touchscreen flatness by observing whether the pressing detection component 30 can touch the first detection probes 12 when pressed against the touchscreen. This effectively improves detection efficiency and ensures accurate flatness detection.

[0018] Specifically, such as Figure 2 As shown, the limiting assembly 20 includes a slide groove 21 disposed on the worktable 10. A limiting block 22 is slidably disposed in the slide groove 21. A push rod 23 extending to the outer side of the worktable 10 is threadedly connected to the limiting block 22. An elastic element 24 is sleeved on the outer periphery of the push rod 23. The two ends of the elastic element 24 abut against the inner side of the limiting block 22 and the slide groove 21, respectively. By sliding the limiting block 22 in the groove 21 and threading the push rod 23 extending to the outer side of the worktable 10 onto the limiting block 22, the limiting assembly 20 achieves its purpose. This allows the limiting block 22 to slide within the slide groove 21 according to the top rod 23, thereby adapting to the limiting block 22 to fix touch screens of different sizes. Furthermore, by providing an elastic element 24 around the top rod 23, with both ends of the elastic element 24 abutting against the inner sides of the limiting block 22 and the slide groove 21 respectively, the limiting block 22 can provide clamping force through the elastic element 24 when adjusting and clamping the touch screen, ensuring that the touch screen cannot shake during the flatness detection process, thus achieving the limiting and fixing of the touch screen to be tested.

[0019] In the above scheme, the pressing detection component 30 includes several sets of support rods 31 disposed on the worktable 10. A top plate 32 is connected to the support rods 31. A first driving component 33 is disposed on the top plate 32. A lower pressure plate 34 is connected to the driving end of the first driving component 33. A second detection probe 35 matching the first detection probe 12 is disposed on the lower pressure plate 34. By connecting the top plate 32 to the support rods 31, the first driving component 33 is disposed on the top plate 32, the lower pressure plate 34 is connected to the driving end of the first driving component 33, and the second detection probe 35 matching the first detection probe 12 is disposed on the lower pressure plate 34, so that when the first driving component 33 drives the lower pressure plate 34 to press down for detection, the lower pressure plate 34 can abut against the surface of the touch screen placed in the limiting groove 11. Then, by checking whether the second detection probe 35 abuts against the first detection probe 12, the flatness of the touch screen is determined to be qualified, thereby realizing the detection of the flatness of the touch screen.

[0020] Furthermore, the pressing detection component 30 also includes a test indicator light 36 disposed on the top plate 32. The first detection probe 12 and the second detection probe 35 are electrically connected to the control system, and the test indicator light 36 and the first drive component 33 are communicatively connected to the control system. By providing the test indicator light 36 on the top plate 32, the first detection probe 12 and the second detection probe 35 are electrically connected to the control system, and the test indicator light 36 and the first drive component 33 are communicatively connected to the control system, in this solution, three sets of first detection probes 12 are disposed in the limiting groove 11. When one of the first detection probes 12 and the second detection probe 35 does not touch, the test indicator light 36 is red. When the first drive component 33 drives the lower pressure plate 34 to press down for detection, and each of the first detection probes 12 and the second detection probe 35 can abut against each other, the test indicator light 36 is green. The operator can judge whether the flatness of the touch screen surface is qualified according to the color of the test indicator light 36, thereby realizing the judgment of whether the flatness of the touch screen to be tested is qualified.

[0021] In order to prevent the pressure plate 34 from scratching the touch screen, as a preferred embodiment, a soft buffer layer is also provided on the side of the top plate 32 facing the limiting groove 11, so that when the pressure plate 34 touches the touch screen surface, the soft buffer layer can provide effective buffering force to prevent the pressure plate from damaging or scratching the touch screen.

[0022] Specifically, the lower pressure plate 34 is matched with the limiting groove 11. By matching the lower pressure plate 34 with the limiting groove 11, misalignment of the first detection probe 12 and the second detection probe 35 during the detection process is effectively avoided, ensuring the detection accuracy of the flatness of the touch screen.

[0023] In summary, in one or more embodiments of this application, this application provides a device for testing the flatness of a touch screen, including a worktable, a limiting groove for accommodating the touch screen on the worktable, limiting components on both sides of the limiting groove on the worktable, a pressing detection component on the top of the worktable, and a first detection probe in the limiting groove. By providing a limiting groove for accommodating the touch screen on the worktable and setting limiting components on both sides of the limiting groove on the worktable, the touch screen can be limited and set in the limiting groove by the limiting components. Furthermore, by setting a pressing detection component on the top of the worktable and setting several sets of first detection probes in the limiting groove, the device can determine whether the flatness of the touch screen is qualified by observing whether the pressing detection component can touch the first detection probe when it presses down against the touch screen, thereby effectively improving the testing efficiency and ensuring the accuracy of flatness testing.
