Method for carrying out special-shaped cutting on glass by utilizing ultrashort-pulse double-light-path laser

Abstract

The invention relates to a device for carrying out special-shaped cutting on glass by utilizing an ultrashort-pulse double-light-path laser. The device comprises a laser (1), wherein laser lights emitted by the laser (1) are incident to surface of a semi-transmission and semi-reflection mirror (4) after passing through an optical shutter (2) and a beam expander (3), the laser lights reflected by the semi-transmission and semi-reflection mirror (4) are vertically incident to a platform (9) by virtue of an optical scanning system, the laser lights transmitted by the semi-transmission and semi-reflection mirror (4) are reflected by a total-reflection mirror (5) and then are vertically incident to the platform (9) by virtue of the optical scanning system, the optical scanning system comprises a galvanometer system (6) and a focus lens (7), and the laser lights which enter into the optical scanning system pass through the galvanometer system (6) and then are focused and emergent by virtue of the focus lens (7). The device for carrying out the special-shaped cutting on the glass by utilizing the ultrashort-pulse double-light-path laser disclosed by the invention has high processing efficiency and good processing effect.

Description

technical field [0001] The present invention relates to a device and method for cutting glass using an ultrashort pulse laser in the form of dual optical paths, in particular to a device capable of cutting Gorilla (gorilla glass), Sodalime (soda lime glass) and Dragontrail glass (Dragontrail glass). The invention relates to a device and a cutting method for special-shaped cutting, belonging to the technical field of cover glass, touch screen and glass micromachining. Background technique [0002] Gorilla (Gorilla Glass), Sodalime (Soda Lime Glass) and Dragontrail (Dragon Trail Glass) tempered glass are widely used in display devices due to their high permeability and high strength. Traditional glass cutting is mainly knife wheel cutting, rod grinding and carbon dioxide laser cutting. Knife wheel cutting can only perform straight line cutting and curved cutting with a large radius on untempered glass. After cutting, slitting is required to obtain a complete shape. For tempe...

AI Technical Summary

Problems solved by technology

For tempered Gorilla (Gorilla Glass), Sodalime (soda lime glass) and Dragontrail (Dragon Trail Glass) glass, it is difficult for the knife wheel to cut

For the cutting of the closed area inside the glass, you can only drill a small hole with a drill bit, and then use a different grinding rod to grind it to the required size. The grinding rod is very worn out and the efficiency is very low.

Carbon dioxide laser cutting can only cut ordinary glass and glass with a lower degree of tempering. After cutting, it also needs a slitting process, and it cannot process internal closed areas.

[0004] With the continuous growth of electronic display industries such as mobile phones and tablet computers, Gorilla (Gorilla Glass), Sodalime (soda-lime glass) and Dragontrail (Dragontrail) glass are used as high-end applications, and traditional processing methods can no longer meet the demand. Therefore, special needs A non-traditional Gorilla (gorilla glass), Sodalime (soda lime glass) and Dragontrail (Dragon trail glass) glass special-shaped processing method and device, and laser, as an advanced processing method in modern industry, has attracted more and more attention from various industries. The feasibility and practicability of glass cutting through lasers have been increasingly verified, but there is no one that can perform Gorilla (Gorilla Glass), Sodalime (soda lime glass) with high efficiency, high quality and high precision. ) and Dragontrail tempered glass special-shaped cutting equipment and process
