Description

Technical Field

[0001] This utility model relates to the field of glass welding technology, and more specifically, to a glass welding vacuum fixture. Background Technology

[0002] Glass laser welding involves stacking two layers of glass together. An ultrafast laser is focused onto the lower layer of material to be welded through a focusing lens. The short pulse and high frequency of the ultrafast laser generate nonlinear absorption within the glass material, forming a low-density plasma. After melting the material at high temperature, the plasma rapidly solidifies, forming a weld pool (filling the gap). During the relative movement between the focal point and the material to be welded, the weld pool is distributed along the movement trajectory, ultimately forming the welding trajectory.

[0003] This application addresses the shortcomings of existing technologies. Glass is a brittle and fragile material, and glass welding differs from metal welding. Common glass welding platforms are typically solid platforms with flat surfaces or vacuum adsorption platforms that only adsorb the bottom single-layer glass. The upper layer of glass is welded by pressing it down with pressure blocks. Under inertia, the pressure blocks are prone to slipping, which affects the glass welding effect. Furthermore, the air gap between the two layers of glass prevents them from being completely adhered, which also seriously affects the glass welding effect. It is not convenient to firmly fix the double-layer glass, thus affecting the welding effect. Utility Model Content
