Description

Technical Field

[0001] The utility model relates to the field of ultra-thin flexible glass, in particular to the field of equipment for producing, testing and inspecting ultra-thin flexible glass. Background Art

[0002] In the ever-changing world of technology, glass is widely used in the electronics industry. Market demand for increasingly thinner cover glass for touch screens and protective glass has made ultra-thin glass a key development trend. UTG (Ultra-Thin Glass) has become a key enabler for future flexible active-light-emitting organic displays. UTG is a high-strength, ultra-thin glass material used in the manufacture of foldable screens and other flexible display devices. Its high strength and ultra-thinness, combined with excellent transparency and durability, make it an ideal material for flexible displays. The manufacturing process for UTG is complex and requires high-tech equipment and techniques. First, the glass material is heated to a high temperature and then stretched into a specific shape. This shape enables UTG to bend and twist strongly while maintaining its transparency. The technology for manufacturing UTG is constantly evolving, and its applications will expand in the future. It will be used to manufacture more complex flexible display devices, such as wearables, foldable e-books, and bendable smartphones. In short, UTG ultra-thin glass is the helmsman of future flexible displays. Its powerful properties make it an ideal material for manufacturing flexible displays. For example, the public document with announcement number CN113060941A, publication date 2021-07-02, and patent name "Ultra-thin flexible glass and its preparation method and application" discloses ultra-thin flexible glass.

[0003] Since the basic thickness of the ultra-thin flexible glass currently under research is 30-150μm, it has a certain degree of toughness and softness. After some special designs, ultra-thin flexible glass of unequal thickness is obtained by grooving and thinning one side of the original glass. This type of ultra-thin flexible glass has thicker plates on both sides and thinner plates in the middle. The thinner part in the middle is called the groove area. After strengthening, the ultra-thin flexible glass monomers of unequal thickness are covered with PE film for performance testing and appearance testing. The qualified products are cleaned and then covered with a layer of protective film before being circulated to the rear for coating. The coating operation is performed on the groove surface. Therefore, when applying the protective film on the front end, it is necessary to ensure that the groove surface and the glass surface are correctly distinguished. The existing method of distinction is manual distinction, which is achieved by touching and feeling the concave and convex feeling of the critical difference in thickness of different areas of the glass to distinguish the groove surface and mark it on the PE film. The disadvantages of manual differentiation are obvious. The operation efficiency is slow and the difficulty of differentiation is different due to the differences in glass raw materials, groove area thickness difference design, preparation process, etc. Theoretically, there must be errors in differentiation by touch, and differentiation and confirmation must be carried out before and after coating the protective film to ensure that the protective film coated on the groove surface is a heavy film, which is time-consuming and labor-intensive. Wrong rework of the protective film will consume a large amount of film material, and the circulation of products with incorrect groove surface differentiation to the back-end process will cause the glass to be scrapped after the coating operation, which greatly increases the cost. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to realize a device capable of efficiently distinguishing groove surfaces of ultra-thin flexible glass with unequal thicknesses.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a device for distinguishing the groove surface of ultra-thin flexible glass, the device is provided with a loading platform for placing the ultra-thin flexible glass, and a ranging unit is provided directly above the loading platform for obtaining distance information from the loading platform downward. The ranging unit is connected to and outputs a distance signal to a controller, and the controller is connected to output prompt information to a warning light.

[0006] The distance measuring unit is fixed above the object platform through a bracket or a frame connected to the object platform, and the distance measuring unit is a laser distance measuring device.

[0007] The warning light is fixed to the outside of the shell through a bracket or a frame connected to the loading platform.

[0008] The controller is connected to an interaction unit, and the interaction unit includes a display screen for displaying distance measurement data.

[0009] The loading platform is provided with a limiting protrusion for limiting the placement position of the ultra-thin flexible glass, and the distance measuring unit detects the position in the groove area of ​​the ultra-thin flexible glass.

[0010] The carrier platform is wrapped in a shell, and an opening for taking and placing the ultra-thin flexible glass is arranged on one side of the shell.

[0011] The interaction unit comprises a button for controlling the operation of the distance measuring unit.

[0012] Compared with the traditional manual distinguishing method, the uneven-thickness ultra-thin flexible glass groove face distinguishing device is more practical, makes the distinguishing of the ultra-thin flexible glass groove face simpler, realizes single-person rapid operation and can realize a high-efficiency operation mode with a very high distinguishing accuracy, and can greatly reduce the problem of low efficiency caused by multiple rework of the uneven-thickness ultra-thin flexible glass cover plate in the process of covering the PET protective film, thereby greatly saving the production cost.

[0017] The specific embodiments of the utility model are further described in detail as follows by comparing the drawings and through the description of the embodiments, the shape, structure, mutual position and connection relationship between the parts, the action and working principle of each component involved, manufacturing process and operation and use method, etc., to help the skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the utility model.

[0018] The ultra-thin flexible glass groove face distinguishing device simplifies and facilitates the personnel operation in the operation process, effectively solves the problems of slow groove face distinguishing speed, high difficulty, low operation efficiency, etc. in the process of covering the protective film after the uneven-thickness ultra-thin flexible glass monomer is strengthened, simultaneously speeds up the product circulation speed, reduces various raw material losses and glass monomer damage quantities caused by groove face distinguishing errors, greatly saves the product preparation cost, and the specific structure is shown in Figure 1 .

[0019] The ultra-thin flexible glass groove surface distinguishing device is provided with a stage 1 for placing the ultra-thin flexible glass. The stage 1 is a horizontal table. The ultra-thin flexible glass can be directly placed on the stage 1 for testing. The core device of the test is a distance measuring unit 2 provided directly above the stage 1 for downward acquisition of distance information from the stage 1. The distance measuring unit 2 preferably adopts a laser distance measuring device.

[0020] In order to prevent other factors from interfering with the test, the stage 1 is set in a sealed shell with only one side open. The opening is used to take and place the ultra-thin flexible glass. The distance measuring unit 2 is inside the shell and is fixed directly above the stage 1 through a bracket or a frame connected to the stage 1. The stage 1 is provided with a limit bump to limit the placement of the ultra-thin flexible glass. The detection position of the distance measuring unit 2 is in the groove area of ​​the ultra-thin flexible glass. By measuring the time it takes for the laser beam to reflect back, the surface difference of the object is detected and calculated, and the groove surface of the glass is distinguished. This makes it easier for employees to distinguish the groove surface, solves the problem of difficulty in distinguishing the front and back before applying the protective film, and the low accuracy, and ensures that the back-end coating can operate correctly. The ultimate goal is to solve the problem of single unit damage and raw material loss caused by incorrect distinction of the groove surface of ultra-thin flexible glass of unequal thickness, greatly saving product costs.

[0021] During the test, first, place the ultra-thin flexible glass (pictured) with an unknown groove surface and uneven thickness flat inside the device, ensuring that the front end fits into the internal limit bump and that the laser emitter can correspond to the groove in the middle of the glass; then press the button to turn on the laser emitter to detect the glass. The laser emitter emits laser light to illuminate the surface of the object being tested, and the sensor receives the reflected light beam. The time difference is calculated to detect the drop on the surface of the object. The distance between the unit and the emitter is analyzed based on the data measured by the internal laser receiver to determine whether the upward surface is the groove surface. Because the detection distance of the groove surface and the non-groove surface is different, a warning light 3 is installed on the outside of the shell for efficient prompting. If the detection is a groove surface, the green light will be on, and if it is a non-groove surface, the red light will be on. It is simple and clear.

[0022] The entire device can be equipped with a controller 4. The distance measuring unit 2 is connected to and outputs a distance signal to the controller 4. The controller 4 is connected to output prompt information to the warning light 3. The controller 4 processes the data. The controller 4 is connected to an interactive unit 5. The interactive unit 5 includes a display screen that displays the distance measurement data and buttons that control the operation of the distance measuring unit 2. The controller 4, interactive unit 5, warning light 3, etc. can be fixed to the outside of the housing via a bracket or a frame connected to the loading platform 1.

[0023] The ultra-thin flexible glass groove surface differentiation device simplifies employee operations and reduces operational difficulty. It can effectively reduce the damage rate of product bending after manual touch differentiation and the resulting performance abnormalities; it has a very high yield and excellent performance; through laser sensing detection instead of traditional manual touch, it can quickly and accurately distinguish ultra-thin flexible glass groove surfaces of unequal thicknesses, which can greatly improve product preparation efficiency, reduce damage and material loss in the process, and ultimately achieve the goal of reducing costs.

[0024] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
