Glass cutting machine based on laser guide cutting

Abstract

The invention discloses a glass cutting machine based on laser guide cutting, which comprises a laser guide cutting device, a cooler, a cutting knife body and a dust exhaust apparatus which are sequentially suspended on the bracket in parallel along the cutting motion direction, wherein the laser guide cutting device emits a laser beam on the glass surface to be cut to form a guide cutting groove; the cooler comprises a first air nozzle which is arranged on the first supporting plate bottom surface and faced with the guide cutting groove; the first air nozzle inputs cooling gas via a gas input pipe; the cutting knife body comprises a cutting rack connected with the bracket, and a cutting knife wheel connected to the bottom of the cutting rack through a wheel pin; the dust exhaust apparatus comprises a first dust exhaust head which is arranged on a second supporting plate bottom surface and faced with the cutting knife wheel; and the vacuum pull of the first dust exhaust head is supplied by an electric exhaust blower through a dust exhaust hose. The glass cutting machine implements laser guide cutting and guide cutting groove quick cooling, enhances the cutting precision and reduces the horizontal cracks and glass chippings. The glass cutting machine can perform quickly dust exhausting on the glass chippings so as to prevent the glass chippings from being attached to the glass surface, thereby reducing the pollution.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a glass cutting machine based on laser cutting. Background technique [0002] At present, the demand for glass in the market is increasing day by day, and there are more and more types and sizes of widely used glass. This puts forward higher requirements for the performance and dimensional accuracy of the glass. Small size, high strength and rigidity, uniform material, and require high efficiency and speed in glass cutting and production. [0003] Usually, in glass cutting, a roller made of diamond sintered body or superhard alloy with a diameter of several millimeters and a ridgeline on its circumference moves while applying a certain pressure on the glass surface; It moves while penetrating into the glass surface, and moves while forming horizontal scratches with a width of several micrometers in depth and width, and at the same time, forms tens of μm perpendicular to the glass surface ins...

AI Technical Summary

Problems solved by technology

[0004] Among them, vertical cracks are a necessary condition for the subsequent glass separation process. However, the horizontal scratches generated during the scribing process will not only affect the edge quality of the glass after separation, that is, the fracture surface is not smooth enough after the glass is broken, but also excess glass debris will appear.

Glass debris will adhere to the glass surface and cause scratches or pollution to the glass surface in the subsequent process, thus directly affecting the quality of the product; at the same time, the raised glass debris will also pollute the environment of the clean workshop
