Abstract

The invention is applicable to the drilling filed of a hard and crisp material, and provides a laser drilling method for glass. The laser drilling method for the glass comprises the steps of dividing a through hole to be laser drilled into a plurality of processing layers, and processing the glass layer by layer by the laser, wherein the process path of each processing layer is an inner cycloidal path. According to the laser drilling method for the glass, the through hole to be laser drilled is divided into the plurality of processing layers, and the process path of each processing layer is the inner cycloidal path, therefore the operation of frequently turning on or off the laser can be reduced, and the blast points at the drilling place or the glass crisp caused by the sudden change of the first and last pulse delay or power of a laser device can be prevented; meanwhile, and the laser drilling efficiency can be greatly improved due to the operation of reducing turning on or off the laser.

Description

technical field

[0001] The invention belongs to the field of drilling of hard and brittle materials, in particular to a laser drilling method for glass. Background technique

[0002] With the development of industry and the diversity of material processing, many industries need to use hard and brittle materials, but the drilling of hard and brittle materials has become a difficult point in technology and manufacturing. Because hard and brittle materials are easily brittle in the drilling For example, the traditional machining drilling method is a hard contact method, which is very easy to crack the entire material, resulting in relatively lower yields, serious consumption of auxiliary consumables, serious pollution, and poor processing accuracy; while laser processing has become a manufacturing The mainstream processing method in the industry, but the existing laser drilling of glass also has many defects, such as too much laser power, which will cause thermal effects and ca...
