Description

Technical Field

[0001] The invention relates to the field of laser cutting equipment, in particular to a longitudinal focus laser invisible cutting device. Background Art

[0002] Laser cutting is required during device processing, and traditional laser cutting focuses the laser on the surface of the material. Due to the edge absorption of the laser, laser processing will produce microcracks or heat-affected zones. In addition, the cutting seams produced by the laser will cause material waste, and the pollution caused by the splashing material deposited on the surface of the material also requires subsequent additional processes to be processed.

[0003] According to a device and processing method for longitudinal multi-focus laser invisible cutting of brittle materials disclosed in the patent document with the existing publication number CN114012249A, the device includes a machine tool working platform, an ultrashort pulse laser, and a laser beam spatial light modulator. The laser beam emitted by the ultrashort pulse laser is spatially shaped and split by the ultrashort pulse laser beam spatial modulator to form ultrashort pulse laser sub-beams with staggered positions in the X or Y direction and different focuses in the Z direction. The machine tool working platform includes a first motion platform and a second motion platform. The first motion platform is installed on the bed base, and the second motion platform is installed on the first motion platform. When the technical solution is used, the laser beam spatial light modulator is used to split the ultrashort pulse laser and cut the brittle material in parallel, so as to achieve both processing efficiency and processing quality. With respect to the above technical solution, although the solution realizes fast cutting, it is not possible to limit and fix the material while dissipating the heat during cutting, which is inconvenient when used.
