Description

Technical Field

[0001] The utility model relates to the technical field of cover plate detection, and more specifically, to an automatic cover plate detection device. Background Art

[0002] With the rapid development of automotive electronic technology, in-vehicle displays have become an indispensable part of modern cars. These displays not only provide entertainment and navigation functions for drivers and passengers, but also carry important vehicle information and safety tips. Therefore, the reliability and quality requirements of in-vehicle displays are becoming increasingly stringent. The reliability of in-vehicle displays depends to a large extent on the cover plate that is in direct contact with it. As a protective layer of the display, the cover plate not only needs to have excellent light transmittance and weather resistance, but also needs to maintain a high degree of flatness and consistency during the bonding process. However, in the existing in-vehicle cover plate manufacturing process, a common challenge is the arch warping of the cover plate after chemical tempering treatment.

[0003] Chemical tempering is an important step to enhance the strength and durability of glass, but this process often leads to inconsistent stress on the front and back sides of the glass, resulting in arch warping. In the subsequent ink screen printing process, the ink may be randomly printed on the concave or convex surface, resulting in uneven ink distribution and affecting the display effect. What is more serious is that when these cover plates are sent to the client for full display lamination, due to the inconsistent arch direction, bubbles and debonding will occur during the lamination process, seriously affecting the yield and reliability of the product;

[0004] At present, in order to solve this problem, some manufacturers try to manually detect and adjust the arch direction of the cover plate, but manual detection is greatly affected by subjective factors and it is difficult to ensure the accuracy and stability of the detection. Therefore, we make improvements on this and propose an automatic detection device for cover plates. Utility Model Content
