AI Technical Summary

Technical Problem

Existing technologies cannot accurately assess the bonding strength of UTG coatings without damaging the UTG substrate, and the force applied by traditional cross-cutting tools is uncontrollable, resulting in incomplete cutting of the coating or cracking of the UTG substrate, leading to poor repeatability of test results.

Method used

An ultrathin flexible glass coating adhesion testing device was designed. It uses multiple parallel blades and ensures constant pressure cutting through limiting blocks and guide grooves. The cutting force can be adjusted by adjusting components to adapt to different glass types and sizes.

Benefits of technology

It achieves constant and controllable cutting force without damaging the UTG substrate, ensuring uniform cutting and cutting only the coating, thus improving the repeatability of the test and the versatility of the device.

Abstract

The present application belongs to the technical field of ultra-thin flexible glass production, and more particularly relates to an ultra-thin flexible glass coating adhesion testing device. A blade (2) is arranged at the lower part of a device base (1), a rod body (3) is arranged at the upper part of the device base (1), a limiting block (4) is arranged on the rod body (3), and a guide long groove (6) is arranged on a device frame (5). The blade (2) comprises multiple blades, and the multiple blades (2) are arranged in parallel. The ultra-thin flexible glass coating adhesion testing device can control the blade to exert constant pressure on the coating of the ultra-thin flexible glass, realize constant and controllable cutting force, avoid the phenomenon that the UTG substrate is broken or the coating is not cut through due to uneven force, and ensure uniform cutting and cutting of the coating only.
