Laser equipment for cutting glass and cutting method

Abstract

The invention discloses laser equipment for cutting glass and a cutting method. A laser generator and a galvanometric scanning system are in data communication with an industrial personal computer through a communication system so as to control a galvanometer to generate strip laser spots during a straight line machining process and generate arc-shaped laser spots during an arc line machining process, so that the laser machining spots precisely coincide with a preset cutting path. A cooling fluid nozzle is mounted below the galvanometer and is used for spraying fluids to cool regions on which the laser heating is carried out, so that a workpiece to be machined is cracked along the preset cutting path under the actions of cold and hot pressures. The workpiece to be machined is adsorbed by an adsorption platform which is mounted on a DD ((Direct Drive) motor; the DD motor is mounted on a Y-shaft moving system; and the galvanometer is mounted on a Z-shaft moving system which is mounted on an X-shaft moving system. When the arc line machining is carried out, the industrial personal computer controls the DD motor to drive the workpiece to rotate and is matched with the motions of an X shaft and a Y shaft at the same time, so that the rendezvous point of the laser spots and the cooling fluids is accurately positioned on the preset cutting path always. Thus, the precision cutting of an arc line position of the glass is realized.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, and more specifically relates to a laser device and a cutting method for glass cutting. Background technique [0002] In the glass processing industry, the traditional method of cutting glass is to first use a diamond wheel to cut a large piece of glass into an approximate finished size, and then use a milling machine / grinder to process the glass in the previous process to the set size. This technology has the problems of complex process, many procedures, low yield rate, long working hours, low precision and heavy pollution. Using laser cutting technology can effectively solve the above problems. [0003] At present, the mainstream laser cutting glass solutions mostly use laser spot to directly heat the glass and vaporize the glass to split the glass. Such a processing method will cause micro-cracks on the edge of the cut, and the section is not smooth, which will affect the strength of t...
