[0002] In the glass manufacturing industry, whether it is laboratory-melted or production-line-melted glass, after processing and strengthening, its scratch resistance is a crucial quality index. This performance is directly related to the service life and safety of glass products. However, traditional methods for evaluating the scratch resistance of glass mainly rely on manual inspection, and this method has many limitations. First of all, the process of manually evaluating the scratch resistance of glass is time-consuming and laborious. Inspectors need to check each piece of glass one by one and judge its scratch resistance through visual inspection or manual scratch tests. With the expansion of production scale and the increase in the variety of glass, this manual inspection method has been difficult to meet the efficient and rapid production requirements. Secondly, manual evaluation is subjective and uncertain. Factors such as the experience, eyesight, and fatigue level of different inspectors may affect the evaluation results, resulting in inconsistencies and inaccuracies in the evaluation results. This subjectivity not only increases the evaluation error but also reduces the reliability of the evaluation results. Summary of the Invention
