Laser machining system and method

Abstract

The invention provides a laser machining system and method. The laser machining system comprises at least two lasers, focusing modules and a beam combining module, wherein the lasers are used for generating at least two laser beams; the focusing modules are arranged corresponding to at least two lasers in a one-to-one mode, and are used for adjusting the focusing positions of the laser beams generated by the corresponding lasers; and the beam combining module is used for receiving at least two laser beams with the adjusted focusing positions and coaxially outputting at least two laser beams. According to the system, the cutting quality of a to-be-machined workpiece can be improved, the reject ratio of the to-be-machined workpiece can be effectively reduced, meanwhile, the application rangeof the lasers can be expanded, and the flexibility of adjusting the focusing positions of the laser beams generated by the lasers can be improved.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a laser processing system and method. Background technique

[0002] Due to its excellent characteristics such as precision, process flexibility, non-contact processing type, and thermal influence on materials, laser cutting is rapidly expanding in the application field of the entire industry. The energy density of the laser beam has a maximum value at the very center of the focus point of the laser beam, and the energy density gradually decreases from the center to the outside.

[0003] Therefore, when the thickness of the workpiece to be processed is greater than the thickness of the area where the energy of the laser beam is focused, multiple times of laser processing are required to cut the workpiece to be processed. However, in the process of multiple times of laser cutting the workpiece to be processed, there is a problem that the large offset of the laser cutting li...
