Abstract
Description
Technical Field
[0001] This utility model generally relates to the field of ultra-thin glass, specifically to the testing of ultra-thin glass, and particularly to a device for testing the limit bending of ultra-thin glass. Background Technology
[0002] With the increasing popularity of LCD monitors, smartphones, and tablets, display products are gradually becoming thinner and lighter. The corresponding electronic glass also needs to be thinner and lighter, leading to the development of ultra-thin glass. Ultra-thin glass (UTG), as its thickness decreases, exhibits better mechanical properties such as flexibility, making it potentially valuable for applications in flexible displays and other fields.
[0003] UTG glass excels in abrasion resistance, surface texture, ultra-thinness, and flexibility, boasting superior durability. It can withstand thousands of bends without damage and remain flat. Bending life is crucial during production. An ultimate bending test is conducted by applying pressure to the bent UTG glass. During this test, the UTG glass is placed on a testing platform after bending. However, the glass is prone to movement during this process, leading to incorrect pressure application and inaccurate test results that do not accurately reflect the glass's ultimate bending capacity, thus affecting the assessment of UTG glass performance. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a device for testing the limit bending of ultrathin glass.
[0005] In a first aspect, a device for testing the limit bending of ultrathin glass is provided, comprising:
[0006] Support platform
[0007] A mobile platform is disposed opposite to the supporting platform and can move in a direction that approaches or moves away from the supporting platform.
[0008] A telescopic rod is disposed on the opposite surfaces of the moving platform and the supporting platform, and moves telescopically on the moving platform and the supporting platform. When extended, the telescopic rod abuts against the edge of the ultra-thin glass to be tested.
[0009] As an alternative implementation, the starting point of the telescopic rod's stroke is located within the support platform or the moving platform, and the ending point of the stroke extends beyond the support platform or the moving platform by a predetermined distance.
[0010] When the distance between the mobile platform and the support platform is less than or equal to a set distance, the telescopic rod moves to the starting position of the travel.
[0011] Alternatively, the telescopic rods on the mobile platform and the support platform can be arranged parallel to each other, or the telescopic rods on the mobile platform and the support platform can be arranged perpendicular to each other.
[0012] As an implementation method, the telescopic rod on the mobile platform abuts against the first edge of the ultra-thin glass when extended, and the telescopic rod on the support platform abuts against the second edge of the ultra-thin glass when extended, with the first edge and the second edge located on both sides of the bending area of the ultra-thin glass.
[0013] As a possible implementation, the mobile platform and / or the support platform are provided with a plurality of telescopic rods, which are arranged sequentially on the mobile platform and / or the support platform.
[0014] As feasible methods, the following also include:
[0015] A pressure bar is disposed on the side of the moving platform away from the supporting platform, and drives the moving platform to move closer to the supporting platform until the ultra-thin glass between the moving platform and the supporting platform breaks.
[0016] As an alternative, the pressure bar is equipped with a pressure sensor, which is used to detect the pressure on the mobile platform in real time.
[0017] As an alternative implementation, a controller is also included, which receives the pressure value from the pressure sensor and uses the pressure at which the ultrathin glass breaks as the current limit bending detection value of the ultrathin glass.
[0018] As an implementation method, both the support platform and the mobile platform are provided with multiple vacuum holes, which are configured to be vacuumed for adsorbing ultra-thin glass on the support platform and / or the mobile platform.
[0019] As a possible implementation, multiple vacuum hole arrays are distributed on the support platform or the mobile platform.
[0020] According to the technical solution provided in the embodiments of this application, a telescopic rod is set on the glass placement platform. When the telescopic rod extends out of the platform surface, it abuts against the edge of the ultra-thin glass to be tested, thereby determining the position of the ultra-thin glass. After the position of the ultra-thin glass is determined, the moving platform is controlled to move, pressing the ultra-thin glass to test its limit bending. When the moving platform moves, the ultra-thin glass will not shift or slide. The testing position of this testing device ensures that the ultra-thin glass is in the bending area of the glass, thus ensuring the accuracy of the limit bending test of the ultra-thin glass.

[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.
[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0034] Please refer to Figure 1 and Figure 3 This embodiment provides a limit bending detection device 10 for ultra-thin glass 20, comprising:
[0035] Support platform 11,
[0036] The mobile platform 12 is disposed opposite to the supporting platform 11 and can move in a direction that approaches or moves away from the supporting platform 11.
[0037] Telescopic rod 13 is disposed on the opposite surfaces of the moving platform 12 and the supporting platform 11, and moves telescopically on the moving platform 12 and the supporting platform 11. When extended, the telescopic rod 13 abuts against the edge of the ultra-thin glass 20 to be tested.
[0038] The detection device provided in this embodiment uses a telescopic rod 13 on a glass placement platform. When the telescopic rod 13 extends out of the platform surface, it abuts against the edge of the ultra-thin glass 20 to be tested, thus determining the position of the ultra-thin glass 20. After the position of the ultra-thin glass 20 is determined, the moving platform 12 is controlled to move, pressing the ultra-thin glass 20 to test its limit bending. When the moving platform 12 moves, the ultra-thin glass 20 will not shift or slide. The detection device ensures that the position of the ultra-thin glass 20 being tested is within the bending area of the glass, thus guaranteeing the accuracy of the limit bending test of the ultra-thin glass 20.
[0039] Ultra-thin glass (UTG) is a thinner type of glass with flexible, bendable properties. The bending area is typically distributed in different regions of the UTG depending on the specific electronic product being used, such as in bi-fold phones or tri-fold phones. Figure 5 The ultra-thin glass 20 shown has a bending area A in the middle, with non-bending areas B on either side. Therefore, the ultra-thin glass 20 is typically folded in half and placed on the ultimate bending test device 10. This device applies pressure to the bending area of the ultra-thin glass 20 until it breaks. The test device consists of two opposing platforms with relatively flat surfaces, typically made of stainless steel. The platform surfaces do not affect the ultimate bending test. The upper platform is a movable platform 12, and the lower platform is a supporting platform 11. The movable platform 12 moves up and down to perform the bending test. Alternatively, the two opposing platforms can be placed side-by-side, with the two platforms moving relative to each other to perform the ultimate bending test on the ultra-thin glass 20.
[0040] In this embodiment, movable telescopic rods 13 are provided on the support platform 11 and the moving platform 12. When the telescopic rods 13 extend out of the platform surface, the edge of the ultra-thin glass 20 can abut against the telescopic rods 13. The position of the ultra-thin glass 20 is fixed and restricted by the telescopic rods 13. Subsequently, the moving platform 12 is moved to press and fix the ultra-thin glass 20, so that the ultra-thin glass 20 will not shift or slide during the subsequent extreme bending and pressing process. The position where the device performs pressure and extreme bending detection is always the bending area of the ultra-thin glass 20, which ensures the accuracy of the detection and / or the accuracy of the data.
[0041] Optionally, the starting point of the travel of the telescopic rod 13 is located within the support platform 11 or the moving platform 12, and the ending point of the travel exceeds a set distance from the support platform 11 or the moving platform 12.
[0042] When the distance between the mobile platform 12 and the support platform 11 is less than or equal to a set distance, the telescopic rod 13 moves to the starting position of the travel.
[0043] In this embodiment, the telescopic rod 13 on the support platform 11 and the moving platform 12 abuts against the ultra-thin glass 20, but it should not affect the ultimate bending test of the device. Therefore, when the support platform 11 and the moving platform 12 on the testing device move relative to each other to a set distance between the two platforms, the telescopic rod 13 needs to be retracted into the platform to make the surfaces of the support platform 11 and the moving platform 12 flat, so as not to affect the subsequent ultimate bending test. Preferably, the starting point of the travel of the telescopic rod 13 is set inside the support platform 11 or the moving platform 12, so that the telescopic rod 13 can be completely returned to the platform and not exposed; the telescopic rod 13 stops when it extends out of the platform by a set distance. This extension distance can be adjusted according to different situations to adapt to different needs and conditions.
[0044] In this embodiment, the position of the ultra-thin glass 20 is fixed by the contact between the telescopic rod 13 and the edge of the ultra-thin glass 20. The telescopic rod 13 is preferably configured as a long strip, forming a shape like... Figure 1 or Figure 3 The structure shown allows the elongated telescopic rod 13 to accommodate glass of different sizes. Alternatively, each telescopic rod 13 can be designed as an intermittent unit to achieve contact and fixation with the ultra-thin glass 20.
[0045] Optionally, the telescopic rods 13 on the mobile platform 12 and the support platform 11 are arranged parallel to each other, or the telescopic rods 13 on the mobile platform 12 and the support platform 11 are arranged perpendicular to each other.
[0046] The configuration of the telescopic rod 13 on each platform is unrestricted. The telescopic rod 13 is used to abut and fix the side edge of the ultra-thin glass 20 to be tested, ensuring that the ultra-thin glass 20 does not shift. Therefore, the corresponding telescopic rod 13 can be configured as follows: Figure 1 or Figure 3 The various arrangements shown include, for example, telescopic rods 13 being arranged opposite each other, with the telescopic rods 13 abutting against the opposite side edges of the ultra-thin glass 20; or telescopic rods 13 being arranged vertically, with the telescopic rods 13 abutting against the perpendicular side edges of the ultra-thin glass 20.
[0047] Optionally, the telescopic rod 13 on the mobile platform 12 abuts against the first edge of the ultra-thin glass 20 when extended, and the telescopic rod 13 on the support platform 11 abuts against the second edge of the ultra-thin glass 20 when extended, with the first edge and the second edge located on both sides of the bending area of the ultra-thin glass 20.
[0048] In this preferred embodiment, the telescopic rods 13 on the two platforms are arranged in a relatively parallel manner. The telescopic rods 13 abut against the first edge 21 and the second edge 22 of the ultrathin glass 20. The first edge 21 and the second edge 22 are located at... Figure 2 The edges on both sides of the bending area of the ultra-thin glass 20 shown are illustrated. The detection device provided in this embodiment can be used to detect ultra-thin glass 20 of different sizes. It is only necessary to place the telescopic rods 13 corresponding to the opposite edges of the ultra-thin glass 20.
[0049] Alternatively, the telescopic rod 13 on the mobile platform 12, in its extended state, abuts against the first edge 21 of the ultra-thin glass 20, and the telescopic rod 13 on the support platform 11, in its extended state, abuts against the third edge 23 of the ultra-thin glass 20, wherein the first edge 21 and the third edge 23 are... Figure 4 The ultra-thin glass 20 shown has two perpendicular sides. The current configuration of the telescopic rod 13 allows for the testing of ultra-thin glass 20 of different sizes and folding configurations, for example... Figure 4 The bending zone of the ultra-thin glass 20 is not in the middle position. In order to ensure the accuracy of the test, pressure needs to be applied to the bending zone for extreme testing. The two perpendicular sides of the ultra-thin glass 20 are respectively abutted against the telescopic rod 13, and bent in the bending zone and placed between the support platform 11 and the moving platform 12 for fixation, and then the subsequent extreme bending test is carried out.
[0050] Optionally, the mobile platform 12 and / or the support platform 11 are provided with a plurality of telescopic rods 13, and the plurality of telescopic rods 13 are arranged sequentially on the mobile platform 12 and / or the support platform 11.
[0051] In the above embodiments, both the mobile platform 12 and the support platform 11 are equipped with only a single telescopic rod 13 for movement. Figure 1 The device shown can also be equipped with multiple telescopic rods 13 on the mobile platform 12 and / or the support platform 11. Different ranges are formed by the different telescopic rods 13 on the upper and lower platforms, so that the ultra-thin glass 20 with different bending areas abuts against the different telescopic rods 13, ensuring that the pressure area for the limit bending test is in the bending area of the corresponding ultra-thin glass 20.
[0052] In the above embodiments, the movement of the telescopic rod 13 can be driven in a variety of ways, such as by screw drive, chain or gear drive, hydraulic drive, or pneumatic drive, and no limitation is made here.
[0053] Furthermore, it also includes:
[0054] A pressure rod 14 is disposed on the side of the moving platform 12 away from the support platform 11, and drives the moving platform 12 to move closer to the support platform 11 until the ultra-thin glass 20 between the moving platform 12 and the support platform 11 breaks.
[0055] like Figure 1 and Figure 3 As shown, a pressure rod 14 is also connected to the moving platform 12. The moving platform 12 is moved by the pressure rod 14, and the pressure rod 14 drives the moving platform 12 to apply pressure to the ultra-thin glass 20 in order to detect the ultimate breakage of the ultra-thin glass 20.
[0056] Furthermore, a pressure sensor is provided on the pressure rod 14, which is used to detect the pressure on the mobile platform 12 in real time.
[0057] In this embodiment, pressure is applied to the placed ultra-thin glass 20 by the moving platform 12 until the ultra-thin glass 20 breaks. The pressure value applied to the ultra-thin glass 20 during the process is detected and recorded. Preferably, a pressure sensor is set on the pressure rod 14, and the data is detected in real time by the sensor.
[0058] Optionally, a controller is also included, which is used to receive the pressure value of the pressure sensor and use the pressure at which the ultrathin glass 20 breaks as the current limit bending detection value of the ultrathin glass 20.
[0059] The detection device in this embodiment is equipped with a controller, which is communicatively connected to the pressure sensor. The controller receives the detection data from the pressure sensor and feeds back the current limit bending detection data of the ultra-thin glass 20 to the user. This data is the pressure value when the ultra-thin glass 20 breaks, which is generally the maximum pressure value transmitted by the pressure sensor.
[0060] The controller is also connected to the drive devices of the telescopic rod 13 and the pressure rod 14. When an extreme bending test is required, the controller drives the pressure rod 14 to move until the distance between the moving platform 12 and the support platform 11 is the set value, and drives the telescopic rods 13 on both platforms to extend out of the platform. Under the current conditions, the ultra-thin glass 20 is bent and placed between the two platforms, and the edge of the ultra-thin glass 20 abuts against the telescopic rod 13. Then, the controller controls the pressure rod 14 to move downward a certain distance to clamp and fix the bent ultra-thin glass 20. Then, the controller drives the telescopic rods 13 on both platforms to retract into the platform, so that the two platforms become flat surfaces again. Then, the controller controls the pressure rod 14 to continue to move downward, applying pressure to the ultra-thin glass 20 until the ultra-thin glass 20 breaks. The pressure value when the ultra-thin glass 20 breaks is the required test value.
[0061] Furthermore, both the support platform 11 and the mobile platform 12 are provided with a plurality of vacuum holes 15, which are vacuum-drawing holes 15 for adsorbing the ultra-thin glass 20 on the support platform 11 and / or the mobile platform 12.
[0062] like Figure 1 and Figure 3 As shown, in this embodiment, vacuum holes 15 are provided on the support platform 11 and the moving platform 12. The ultra-thin glass 20 placed on the platform is adsorbed through the vacuum holes 15, which further ensures the stability of the ultra-thin glass 20 during the detection process and makes it less likely to shift.
[0063] Optionally, a plurality of the vacuum holes 15 are arrayed on the support platform 11 or the moving platform 12.
[0064] In this embodiment, by distributing the vacuum holes 15 in an array, the adsorption force on the ultrathin glass 20 is relatively uniform when the vacuum holes 15 adsorb the glass. This vacuum hole 15 structure further ensures the accuracy of the ultimate bending test of the ultrathin glass 20.
[0065] The above embodiment adds a telescopic rod 13 structure to the extreme bending test platform. The telescopic rod 13 abuts against the edge of the ultra-thin glass 20 to fix the position of the ultra-thin glass 20. The ultra-thin glass 20 is also adsorbed through the vacuum hole 15 to ensure that the glass does not shift or slide during the extreme bending test, making the extreme bending test data of the ultra-thin glass 20 more accurate.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.
[0067] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.
