Abstract

The invention belongs to the field of laser machining, and provides a three-dimensional laser marking method and device and three-dimensional laser machining equipment. The method includes the steps that a curved surface model of an object to be machined is obtained, and the object to be machined is installed on a numerical control rotary worktable; a specific two-dimensional planar texture is mapped to the curved surface model to obtain a mapped curved surface model; a three-dimensional texture mathematic model is obtained after the curved surface model is extracted from the mapped curved surface model; the three-dimensional texture mathematic model is segmented to obtain multiple texture model blocks; the numerical control rotary worktable and the texture model blocks are controlled to rotate by the same angle in the same direction, so that the texture model blocks are sequentially located in a laser machining area of a three-dimensional galvanometer system, and curved surfaces, matched with the texture model blocks, in the laser machining area are sequentially machined. By means of the three-dimensional laser marking method and device and the three-dimensional laser machining equipment, the aim that the curved surfaces in areas of any angle can be machined through lasers can be achieved.

Description

technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a three-dimensional laser marking method, device and three-dimensional laser processing equipment. Background technique [0002] The inherent high-speed, efficient and clean processing methods of laser marking equipment are favored by all walks of life, so they are widely used in many industries such as electronic information, light industry, home appliances, molds, high and low voltage electrical appliances, and jewelry. The processing technology of two-dimensional laser processing equipment that takes the object plane as the marking object has matured day by day. [0003] However, there are still many limitations and defects in the three-dimensional laser processing (marking, etching, engraving, etc., the same below) method that takes the arbitrary curved surface of the object as the laser processing object. For example, a "three-dimensional" laser marking...
