Definitions

  • the present invention relates, in general, to a glass cutting apparatus and a method of cutting glass using the glass cutting apparatus and, more particularly, to a glass cutting apparatus which cuts a glass sheet by forming a crack in the glass sheet using a laser beam and lifting the glass sheet using a bending unit, and a method of cutting glass using the glass cutting apparatus.
  • an object of the present invention is to provide a glass cutting apparatus having a bending unit which minimizes friction between a glass sheet and a stage unit when cutting the glass sheet, thus easily cutting the glass sheet using a relatively small amount of energy, and a method of cutting glass using the same.
  • the bending unit is provided such that the upper end thereof is disposed higher than the upper surface of a stage unit, a medial portion of a glass sheet is lifted while opposite ends thereof sag. Thus, stress is concentrated on the medial portion of the glass sheet to be cut. Hence, the glass sheet can be easily cut even using relatively little energy.
  • the bending unit is disposed behind a laser generating unit, so that the bending unit pushes a cut part of the glass sheet upwards, thus making it easy to conduct the cutting process.
  • the degree of bending of the glass sheet can be controlled by adjusting the height of the bending unit. Therefore, depending on the thickness and size of the glass sheet, the intensity of stress applied to a desired part of the glass sheet to be cut can be adjusted.
  • a plurality of air suction holes is formed in the stage unit, so that the glass sheet is prevented from undesirably sliding, and the air suction holes along with the bending unit can further bend the medial portion of the glass sheet, that is, the part to be cut. Therefore, stress is further concentrated on the desired part of the glass sheet, thus the glass sheet can be cut using relatively little energy more easily.

  • a second carrying unit which moves the bending unit forwards and backwards
  • the first and second carrying units are controlled by a control unit such that a laser generating unit and a bending unit are moved at the same speed, therefore a glass sheet can be pushed upwards by the bending unit while the laser generating unit radiates a laser beam onto the glass sheet.

  • the laser beam is radiated onto the glass sheet at an intensity lower than that before the glass sheet is lifted, thus saving energy, that is, cutting the glass sheet using minimum energy, and ensuring superior quality of cut ends of the glass sheet.
  • the laser beam is gradually reduced in intensity from the leading end of the glass sheet to a trailing end, so that the glass sheet can be cut using the minimum energy required to cut the glass sheet, thus saving energy and enhancing the quality of cut ends of the glass sheet.
  • an intensity of laser beam higher than in the case where the trailing end of the glass sheet is cut straight is irradiated onto the glass sheet.
