    摘要: A method for processing a transparent workpiece including directing a laser beam in a first orientation along a first beam pathway where a first portion of the laser beam includes a first laser beam focal line and generates an induced absorption to produce a first defect segment within the transparent workpiece. The method further includes adjusting the laser beam to a second orientation along a second beam pathway where a second portion of the laser beam includes a second laser beam focal line and generates the induced absorption to produce a second defect segment within the transparent workpiece. Each of the first and second laser beam focal lines include a circular angular spectrum within the transparent workpiece; and at least one of the laser beam focal lines include an internal focal line angle of greater than 10° relative to a plane orthogonal to the impingement surface at the impingement location.

    摘要: A display device includes a pair of glass substrates. On the side of each of the pair of glass substrates, a press mark is formed between a first end of each of the pair of glass substrates and a position at least 0.3 mm but no more than 3 mm away from the first end, another press mark is formed between a second end of each of the pair of glass substrates and a position at least 0.3 mm but no more than 3 mm away from the second end, a scribing groove having a predetermined scribing amount is formed between the press marks, and there are rib marks in the scribing groove.

    摘要: A moil crack-off system for a funnel is provided, wherein a pick-up apparatus is arranged intersectionally above a conveyor that is extended from the shaping process of the funnel, and a pair of ware transfers are arranged in parallel on either side of the conveyor. The funnel that is riding on the conveyor is absorbed at a predetermined position by vacuum pads that are loaded on the carriers of the pick-up apparatus, and is moved in a three-dimensional manner to either of the ware transfers. The ware transfers deliver the three-dimensionally moved funnel to a scoring part and a two-step fire polishing part, which are arranged within the ware transfers, so that the moil of the funnel is cracked off automatically.

    摘要: A laser cutting method for a glass material, includes steps of forming a continuous scribing line at least on one side face of the glass material, and projecting a laser beam onto the scribing line. A laser cutting apparatus for effecting the laser cutting method, includes a laser oscillating source for emitting the laser beam, a light condensing device for condensing the laser beam onto a surface of the glass material, a scribing device for forming the scribing line on the surface of the glass material, and a displacing device for displacing the laser beam on the scribing line following movement of the scribing point.

    摘要: A fluid for use in a glass cutting operation contains two portions. A first portion of the fluid is a highly volatile, nonresidue forming, cutting tool lubricant. The second portion of the fluid is a non-volatile material either dissolved in or carried by the tool lubricant. The non-volatile material is one which forms an encapsulating film along a score placed on a glass surface by a glass cutting tool. This film binds any wing chips to the edge of the score to prevent spalling.
