Laser-based glass cutting, coating removal, and final processing method

Abstract

The invention proposes a method for cutting glass, removing coatings, and performing final processing using a laser, comprising the following steps: applying a coating solution to prevent chemical contact with one or both sides of a raw ultrathin glass sheet for selective chemical treatment; drying this coating solution to form a coating film on one or both sides of the raw ultrathin glass sheet; cutting the raw ultrathin glass sheet into cut-cell ultrathin glass for use in electrical and electronic products; The laser-cut ultrathin glass surface is restored through selective chemical treatment; the ultrathin glass is cleaned, then all coatings on the surface are removed; and chemical restoration is applied to the surface of the ultrathin glass after all coatings have been removed to remove defects or scratches on the glass surface.
