Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] Such as figure 1 As shown, a method of applying laser drilling to the drilling of sapphire sheets comprises the following steps:

[0039] S1: Fix the sapphire sheet on the workbench 1 of the laser equipment (the workbench 1 has a table top 2 holding the sapphire sheet), so that the laser emitting head 4 of the laser equipment is aligned with the pre-punched position of the sapphire sheet;

[0040] S2: Set the parameters of the laser equipment according to the thickness of the sapphire sheet. This step can be divided into 5 steps:

[0041] a: Set the parameters of the laser equipment according to the thickness of the sapphire sheet and the formula ;

[0042] E=1.6...

Abstract

The invention relates to a method for applying laser drilling to sapphire slice drilling. The method comprises a first step of fixing a sapphire slice on an operating platform of a laser device and enabling a laser emission head of the laser device to be aligned to a position to be drilled on the sapphire slice, a second step of setting parameters of the laser device according to the thickness of the sapphire slice, and a third step of starting the laser device to enable the laser device to emit laser beams towards the position to be drilled on the sapphire slice, wherein the second step comprises a first step of setting parameters of the laser device according to the thickness of the sapphire slice and a formula (1), a second step of determining laser emission frequency of the parameters of the laser device according to determined energy in the parameters of the laser device and a formula (2), a third step of determining feed rate of the parameters of the laser device according to determined laser emission frequency of the parameters of the laser device and a formula (3), a fourth step of setting 0.3-0.5 ms as the wave width of the parameters of the laser device, and a fifth step of adjusting Hgt% of the parameters of the laser device to enable average power of the laser device to be 255 W.

Description

technical field [0001] The invention relates to a method for applying laser drilling to the drilling of sapphire sheets. Background technique [0002] Laser drilling is the earliest practical laser processing technology, and it is also one of the main application fields of laser processing. With the rapid development of modern industry and science and technology, more and more materials with high hardness and high melting point are used, while traditional processing methods can no longer meet certain process requirements. Existing sapphire sheets are mainly punched by engraving machines. The so-called engraving machines refer to CNC milling machines that use small tools, high power and high-speed spindle motors. The existing engraving machines have the following defects: [0003] 1. The high-efficiency processing materials of Jingdiao machine are low-hardness materials such as stainless steel and copper, and the hardness of sapphire is second only to diamonds; Jingdiao cons...
