Abstract

The invention provides a laser cutting device which comprises a laser emission module, a focusing lens and a multifocal lens, wherein the multifocal lens is clung to the focusing lens and is arranged between the laser emission module and the focusing lens on the optical path of a laser beam; the laser beam passes through the multifocal lens and the focusing lens and form a plurality of focus points at intervals in the transmission direction of the laser beam. The ultrashort pulse laser beam is modulated through the multifocal lens and the focusing lens, the focus points are focused and formed at intervals in the internal laser beam transmission direction of a transparent material, a filament is formed in the transparent material through ablation by the focus points, a separation path of a filament array is quickly formed in combination with a worktable for moving and bearing the transparent material, and the effects of no fragmentation, high accuracy, high yield, irregular processing and no cumbersome follow-up steps can be achieved. The method has the characteristics of high simplicity in operation, high fineness and good quality of processed samples, high processing efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a laser cutting device and a cutting method. Background technique [0002] Rigid glass has stronger wear resistance and is less likely to shatter in daily collision situations. And as current display devices get thinner, rigid glass becomes a more flexible, lightweight option. In addition, rigid glass is also more suitable for the application of the OGS (one glass solution integrated touch) solution, which provides the function of combining touch and display with a single-layer display material. Then the application of hard glass to actual processing requires technology that can cut these glasses. [0003] Traditional cutting methods include mechanical action and CO2 laser cutting. These methods are only suitable for early hard glass, the thickness can not exceed 20μm, and can not cut the curve, and will cause micro-cracks. The generation of micro-cracks requires carefu...
