Abstract

The invention relates to a laser machining process for rotary body glass products. The laser machining process for the rotary body glass products acts with the help of a laser machining device for rotary body glass products. The laser machining device comprises a machine frame assembly, a station transmission device, a feeding station, a first laser cutting station, a second laser cutting stationand a discharging station, wherein the station transmission device is longitudinally arranged on the machine frame assembly; the feeding station, the first laser cutting station, the second laser cutting station and the discharging station are distributed on the station transmission device in sequence; a feeding device is arranged at the feeding station, a first laser machining head is arranged atthe first laser cutting station, a second laser machining head with the same structure as the first laser machining head is arranged at the second laser cutting station, and a transverse dischargingdevice and an output device are correspondingly arranged at the discharging station; and the station transmission device comprises longitudinal conveying chains arranged on the machine frame assemblyand workpiece clamping fixtures distributed on the longitudinal conveying chains and used for bearing the rotary body glass products. The laser machining device is reasonable in design, compact in structure and convenient to use.

Description

technical field [0001] The invention relates to a laser processing technology for a glass product of a revolving body. Background technique [0002] At present, the biggest disadvantage of the traditional mechanical cutting method is the need to reprocess the processed edges and the resulting low yield. [0003] In mechanical cutting, an abrasive or mechanical wheel is used to score the glass, creating tangential tension along the cutting direction, causing the glass to crack along the scratch. The edge cut by this method is not smooth, has tiny cracks, residual asymmetric edge stress on the material, and residual debris. For many applications, microcracks caused by debris and localized stress will cause device failure, so post-cut edge grinding and / or polishing, or even heat treatment, is necessary to strengthen the edge. In addition, auxiliary agents are needed to assist cutting in mechanical wheel processing, and auxiliary agents may also stick to the edge of the finish...

AI Technical Summary

Problems solved by technology

This method can only produce very shallow cracks, and subsequent processes are required to crack the glass along the cracks, and this method cannot process complex graphics, such as processing inner holes inside the glass.
