Abstract

The invention relates to a cutting method for a circular hole of a panel workpiece, and the cutting method comprises the following steps of: rough cutting and precise cutting. The invention also relates to a cutting system for the circular hole of the panel workpiece. The cutting system comprises a three-dimensional mobile platform, a workpiece sucker, a CCD (charge coupled device) camera and a laser focus component, wherein the laser focus component is arranged above the workpiece sucker which is connected with the three-dimensional mobile platform, and the CCD camera is arranged above the workpiece sucker. According to the cutting method and the cutting system for the circular hole of the panel workpiece, the incision quality and yield of tempered glass with the cutting thickness between 0.3mm and 5mm are greatly improved, and subsequent technological processes are simplified.

Description

technical field [0001] The invention relates to a round hole cutting system and a cutting method for panel workpieces. Background technique [0002] At present, touch panels are basically used in mobile devices and consumer electronics products. The traditional processing method is CNC mechanical cutting. of scrap products. In mechanical cutting, a grinding wheel or a mechanical wheel is used to score the glass, which generates tangential tension along the cutting direction, so that the glass is cracked along the scratch. The edge of this cut is not smooth and has tiny cracks. The material The upper local stress can easily cause the product to break and affect the cutting yield. Therefore, it is necessary to grind or polish the edge after cutting. Some specially tempered glass also requires heat treatment to strengthen the edges. [0003] Laser cutting technology has now become a mature industrial processing technology. In addition to the traditional metal as the main ob...
