A laser engraving machine for processing wooden combs and a method for engraving wooden combs

Abstract

The invention discloses a laser engraving machine for machining a wooden comb. The laser engraving machine comprises a working table, wherein the working table comprises a base capable of moving in X-axis and Y-axis directions; a rectangular machining groove is formed in the center of the base; such curing agents as resins fill in the machining groove, and can be softened under a heating condition; holes are formed in four inner wall surfaces of the machining groove; four heating rods extend out from the holes of the inner walls of the machining groove, penetrate through the curing agents, and extend to the center position of the machining groove; the heating rods comprise resistance wires and covers; the thicknesses of the covers are gradually decreased in the direction from the inner wall to the center of the machining groove; a thermocouple for measuring the temperature of the center position of the machining groove is arranged in the machining groove, and is connected with a temperature control device for feeding the temperature of the center position of the machining groove back to the temperature control device in real time; and the temperature control device can adjust the power amplitude of the heating rods in real time. The laser engraving machine cannot damage the surface of the wooden comb, is simple in structure, needs no fixture, and is excellent in fixing effect.

Description

technical field [0001] The invention belongs to the field of laser engraving, in particular to a laser engraving machine for processing wooden combs and a method for engraving wooden combs. Background technique [0002] Sculpture art is a craft with a long history. Carving patterns and characters on the surface of objects can significantly improve the artistic taste of objects. Traditional carving methods mostly use craftsmen's hand-carving methods, which have extremely high requirements for craftsmen's technical level and have a time cycle. Long, low efficiency, etc., and the level is uneven, it is difficult to be guaranteed. Therefore, in modern wood carving processing, laser processing technology is applied to meet the needs of modern production. The principle of laser engraving is to use the laser beam as a heat source. The light beam is focused on the surface of the workpiece and releases energy. The released energy can generate heat energy on the surface of the workpie...

[0002] Sculpture art is a craft with a long history. Carving patterns and characters on the surface of objects can significantly improve the artistic taste of objects. Traditional carving methods mostly use craftsmen's hand-carving methods, which have extremely high requirements for craftsmen's technical level and have a time cycle. Long, low efficiency, etc., and the level is uneven, it is difficult to be guaranteed. Therefore, in modern wood carving processing, laser processing technology is applied to meet the needs of modern production. The principle of laser engraving is to use the laser beam as a heat source. The light beam is focused on the surface of the workpiece and releases energy. The released energy can generate heat energy on the surface of the workpiece, and locally melt the workpiece. By moving the position of the laser beam, the engraving of the workpiece can be achieved. Purpose, the laser engraving machine can improve the engraving efficiency, make the surface of the engraved place smooth and round, rapidly reduce the temperature of the engraved non-metallic material, and reduce the deformation and internal stress of the engraved object; it can be widely used for various The field of fine engraving of non-metallic materials

[0003] In the laser engraving process of wooden combs, the wooden comb is generally placed on the working platform and fixed with a fixture to fix the laser beam for processing, and the worktable is moved along the XY axis to complete the engraving. The current working platform has a fixture The structure is complex, the fixing effect is not good, and it is easy to loosen, which affects the processing effect
