Abstract

The invention discloses a machining method for punching a small hole on glass, relates to the technical field of glass punching, and aims to solve the technical problems of a current machining method that a low punching yield, a low output yield, hole caving defects and surface heterochrome defects are easily caused. The machining method for punching the small hole on glass comprises the following steps that machining software is started; after a system is reset, a machining interface is entered to select a machining process; the to-be-machined glass is placed on a jig platform of a laser, wherein a BM surface is upward, and an AS surface is downward; the to-be-machined glass clings to a positioning edge of the jig platform, and a negative pressure is adjusted to a preset value, so that the to-be-machined glass is firmly fixed on the jig platform; a small hole negative pressure dust drawing device is started, and a CCD visual system is used for edge grabbing and positioning, so that a green ray is emitted by the laser to perform small hole machining; after the small hole is machined, firstly the small hole is cleaned with clear water, and then a hole wall is cleaned by pointing an air gun at the small hole; and water on the glass is wiped with a dustless dry cloth.

Description

technical field [0001] The invention relates to the technical field of glass punching, in particular to a processing method for punching small holes in glass with a green laser after pressure. Background technique [0002] As glass is more and more widely used in the electronics industry, due to its low cost, high strength after pressurization and high surface tension, it is very suitable for electronic fields such as mobile phones, tablet computers or desktop computers. [0003] The traditional glass micro-processing technology has always been cut by CNC (numerical control machine tool). Since glass is a brittle material, the stress on the glass surface after pressurization is large. Using CNC and other processing can easily lead to chipping in the processing area, which requires additional chamfering Eliminate chipping. In order to solve the above problems, most of the current glass industry adopts laser processing. Compared with the previous CNC processing technology, si...
