Abstract

The invention discloses a method for controlling energy of a laser drilling machine. The method is characterized by comprising the steps that during laser drilling, non-constant laser power is provided, and the non-constant laser power is utilized for carrying out laser drilling , wherein a method for controlling the non-constant laser power comprises the following steps that 1, waveform parameters are edited, the waveform parameters are sent to a waveform controller, the waveform controller outputs waveform pulse, and the waveform pulse drives a laser to work; and 2, the waveform parameters are changed, the waveform parameters pass through the waveform controller, different kinds of waveform pulse are generated, and the laser is driven to output different kinds of power. According to themethod, a waveform is divided into small sections, the DA values of the small sections are modified, different waveforms are set randomly, different waveforms drive the laser to provide non-constant power, and the drilling taper of laser drilling is improved.

Description

technical field [0001] The invention relates to the field of laser control, in particular to a method for controlling the energy of a laser drilling machine. Background technique [0002] Today, with the continuous advancement of cutting technology, the application of laser technology has greatly improved the efficiency and accuracy of cutting, not only in a wide range of industries, but also in a huge number of materials suitable for processing. With alumina (Al 2 o 3 ) and aluminum nitride (AlN) ceramic products are increasingly used, and the demand for cutting and drilling is also increasing; using laser to drill ceramics is a kind of laser cutting, and the minimum hole diameter that can be processed is 60um; The traditional laser drilling machine uses fixed energy when drilling, the power of the laser is constant, and the taper of the drilled hole is poor. Contents of the invention [0003] The object of the invention of the present invention is to provide a laser d...
