Description

Technical Field

[0001] The utility model belongs to the technical field of ultra-thin flexible glass. Specifically, the utility model relates to an impact performance testing instrument for an ultra-thin flexible glass cover plate. Background Technique

[0002] With the replacement of electronic products, glass has been widely used in the electronic industry. The market's requirement for the thickness of touch screen glass cover plates and protective glass is getting thinner and thinner. The ultra-thinning of glass has become one of the important development trends of glass. Ultra-thin glass cover plates have received more and more attention from listed companies in the electronic display industry and are mainly used in folding mobile phones, folding laptops, and various wearable electronic devices. Ultra-Thin Glass (UTG) refers to glass with a thickness less than 100 μm and flexibility. Due to its advantages such as high transparency, stability, and impact resistance, UTG is widely used in various electronic industries. Its bendable characteristic has marked a major milestone in the folding display screen industry and has become an important player in the field of foldable flexible cover plates after CPI cover plates.

[0003] One of the most important properties of UTG as a glass cover plate is its impact resistance (ball drop, pen drop). Since the basic thickness of currently studied ultra-thin glass is 30 - 100 μm, due to its thinness, it has a certain degree of flexibility. When tempering ultra-thin flexible glass, based on the properties required for its end-use fields, the commonly used method is the low-temperature ion exchange method. The glass is placed in a molten alkali salt solution, and the strength of the glass is increased through ion exchange. During the actual production process, the glass needs to be inserted into a specific tempering tooling, cleaned, and then sent to a tempering furnace for tempering. However, in the current tempering process, uneven points may occur. The reason for this defect is that small particle contaminants adhere to the glass surface during cleaning or tempering, affecting ion replacement and forming an uneven surface on the glass with one side concave and the other side convex. Due to the special performance requirements and usage scenarios of UTG products, tempering must be carried out to enhance the surface stress of the glass to ensure the impact resistance of UTG. To ensure that the impact performance of UTG products is qualified, impact performance testing is generally carried out after UTG production is completed. The impact performance includes ball drop performance and pen drop performance.

[0004] A Chinese patent with the application number 202210361788.3 discloses a performance testing device for cover glass. The testing device includes a test bench, an impact resistance testing device, and an anti-friction testing device. A support member is provided on the top of the test bench; the impact resistance testing device includes a storage box located above the glass to be tested, and the sphere outlet of the storage box is opposite to the position to be tested on the glass to be tested. A release device is provided on the storage box; the anti-friction testing device includes a test brush and a first driving component, and the first driving component is used to drive the test brush to reciprocate on the surface to be tested of the glass to be tested.

[0005] It is desired to provide an improved impact performance testing instrument for ultra-thin flexible glass covers, especially a device that can meet the testing requirements for the impact resistance performance of UTG. Summary of the Utility Model

[0018] Next, with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present utility model will be further described in detail. The purpose is to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present utility model, and to facilitate its implementation.

[0019] As shown in Figure 1 and Figure 2 The present utility model provides an impact performance testing instrument for an ultra-thin flexible glass cover plate, including a carrier platform 1 for placing the glass cover plate, a partition for supporting the testing tool, and a height frame 2 provided on the carrier platform 1. A positioning groove 4 for accommodating the partition and a through hole for allowing the testing tool to pass through are provided on the height frame 2, and the through hole is located above the carrier platform 1.

[0020] Specifically, as shown in Figure 1 and Figure 2 The carrier platform 1 is horizontally arranged, and the top surface of the carrier platform 1 is a horizontal plane for placing the glass cover plate. The height frame 2 is vertically arranged on the top surface of the carrier platform 1. A plurality of positioning grooves 4 are provided, and all the positioning grooves 4 are arranged in sequence along the vertical direction. The through hole is vertically penetrated through the height frame 2 and penetrates through all the positioning grooves 4. The through hole is a circular hole. A scale line 3 for marking the height position of the partition is provided on the height frame 2. The scale line 3 marks the height positions of the respective positioning grooves 4. The partition can be selectively inserted into one of the positioning grooves 4. The height position of the partition can be accurately judged through the scale line 3, which is convenient for placing the partition at a set height, and further the height position of the testing tool can be accurately judged. The testing tool is spherical or pen-shaped.

[0021] As shown in Figure 1 and Figure 2 The height frame 2 includes a connected first support portion and a second support portion. The lower end of the first support portion is fixedly connected to the carrier platform 1, the upper end of the first support portion is fixedly connected to the lower end of the second support portion. The width of the first support portion is smaller than the width of the second support portion. The positioning groove 4 and the scale line 3 are provided on the second support portion. The positioning groove 4 is a groove formed by extending horizontally from one side surface of the second support portion towards the inside of the second support portion. The through hole extends vertically downward from the top surface of the second support portion to the bottom surface of the second support portion. There is a certain distance between the bottom surface of the second support portion and the top surface of the carrier platform 1. The through hole guides the testing tool to fall straight down to ensure the reliability of the test.

[0022] As Figure 1 and Figure 2 shown, the impact performance testing instrument for the ultra-thin flexible glass cover plate of the present utility model further includes a plurality of reinforcing plates 5 connected to the carrier 1 and the height frame 2.

[0023] As Figure 1 and Figure 2 shown, the reinforcing plate 5 is an L-shaped structure. The reinforcing plate 5 is fixedly connected to the first support portion and the carrier 1. The setting of the reinforcing plate 5 can improve the connection strength between the carrier 1 and the height frame 2 and enhance the bearing capacity.

[0024] When testing the performance of the dropped ball or pen, prepare the glass cover plate and place it on the top surface of the carrier 1. Place the partition into the positioning groove 4 of the height frame 2 with a specific scale. Place the test tool into the through hole of the height frame 2. The test tool is supported by the partition below. After confirming that the spherical / pen-shaped test tool is stationary and vertical, pull out the partition. The test tool falls along the through hole onto the glass cover plate below. Finally, determine whether the impact resistance performance of the glass cover plate meets the requirements.
