Description

Technical Field

[0001] The utility model relates to the technical field of glass production and detection, in particular to a scratch-resistant glass testing device. Background Art

[0002] Glass is the most mainstream exterior material for smartphones or car displays. According to consumer survey data, scratch resistance is a major consideration for consumers when purchasing mobile phones, and they are more willing to pay for improved performance. With the expansion of the surface glass coverage of smartphone screens and the improvement of aesthetics, higher requirements are placed on the scratch resistance of glass. The market demand for scratch-resistant glass is growing, and its quality requirements are also getting higher and higher. The requirements for the scratch resistance of glass are also becoming more and more stringent. Scratch-resistant glass needs to be tested for scratch resistance before leaving the factory to ensure that the product quality meets the product quality requirements.

[0003] For example, a scratch-resistant glass and its testing device with application number 202111016998.0, the scratch-resistant glass and its preparation method disclosed in the device select a glass matrix of specific components and adopt a secondary chemical strengthening treatment to obtain glass with excellent scratch resistance. The base carrier of the scratch-resistant glass testing device has an adjustable reciprocating speed along the longitudinal direction, the glass placement table has an adjustable reciprocating speed along the transverse direction, and the detection pressure of the pressurizing device is adjustable. However, after analyzing the above-mentioned comparative patents and most of the existing testing devices, it was found that most testing devices need to use other auxiliary tools to measure the size of the glass when testing the scratch resistance of the glass, and most of them use rigid fastening when tightening, which can easily cause the glass to break and affect the normal test results.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a scratch-resistant glass testing device is proposed. Utility Model Content
