Abstract

The invention discloses a correction method of a laser drilling machine and the laser drilling machine adopting the correction method. The laser drilling machine comprises a galvanometer machining system, a visual positioning system in linkage with the galvanometer machining system and a workbench, and the workbench is provided with a correction area and a machining area. The correction method comprises the following steps: acquiring a correction period and a correction position; automatically controlling the galvanometer machining system to process a graph in the correction area according to the correction period and the correction position, and controlling the galvanometer machining system to move by a preset distance after machining is completed so as to enable the visual positioning system to obtain the offset of the graph; automatically updating an offset parameter between the galvanometer machining system and the visual positioning system according to the offset; and conducting continuous positioning machining on a workpiece to be machined in the machining area through the laser drilling machine by using the updated offset parameters. Therefore, the machining precision and the machining efficiency of the laser drilling machine can be improved.

Description

technical field

[0001] The invention relates to the technical field of laser drilling machines, in particular to a calibration method for a laser drilling machine and a laser drilling machine using the same. Background technique

[0002] In related technologies, with the development of society, people have higher and higher requirements for processing precision while requiring improvement in production efficiency. Laser drilling machine is an industrial production equipment that needs to take into account both high production efficiency and high precision.

[0003] However, when the laser drilling machine uses the laser to process the workpiece, with the long-term use of the galvanometer, its accuracy will change due to external factors such as ambient temperature, humidity, vibration, and its own temperature drift, and there will be overall drift, such as : A certain type of galvanometer will drift 0.6mrad under long-term work for 8 hours. According to the calculation of t...
