Description

1 TARIFF LASER GLASS CUP CUTTING MACHINE TECHNICAL FIELD The invention is specifically designed for cutting glass cups on mass production lines. It is related to laser cutting machines. STATE OF THE ART In glass manufacturing, cutting usually occurs after the molten glass mass has been poured into a mold. or the excess parts called "burrs" after inflation are removed in a controlled manner 10 It is the process of separating the cup from its stem. This process standardizes the cup size and It ensures that the rim of the glass becomes smooth. Applied in the technical field. The basic cutting methods are hot cutting, cold cutting, and annealing-grinding. These are the methods. The hot cutting method is also called flame cutting and is used in production. In the production line, especially in automatic machines, the hot cup coming out of the mold is at the desired 15 The excess upper dimension is removed with the help of a high-temperature flame (oxygen-gas burners). It is melted and separated from the stem. After hot cutting, the rim of the glass is slightly rounded. And it becomes smooth. In the cold cutting method, the marking is usually done with diamond or laser. The process is carried out. It is applied after the glass has completely cooled and solidified. This is the method. A diamond cutter makes a thin cut from the top of the glass with a diamond-tipped blade. 20 (The mark) is removed. Then, a sudden heat shock (hot and cold water) is applied to completely remove the scratch from the glass. It is made to crack and separate in a controlled manner. In laser cutting, however, it is much more... Laser beams for glassmaking of thin-walled crystal glasses requiring high precision. Micro-cracks are created on its surface, resulting in a perfect cut. In edge finishing methods, the cutting process also includes annealing and grinding. 25 Afterwards, the rim of the glass becomes microscopically very sharp and rough. This To remove the sharpness and make the glass ready for use, rim the cup It is passed through sanding belts or brushes (grinding). To polish the edges. It is passed through a very high flame again, so that the edge of the glass becomes smooth. (polishing / fire-finishing). 30 Document number US11964898B2 describes "a glass made of clear oxide glass." The plate cutting method uses a laser from a mid-infrared (mid-IR) laser source. 2 It involves directing the beam of light onto the main surface of the glass plate. The wavelength of the laser beam... By adjusting the settings, the absorption depth of the laser beam on the glass plate is controlled. The glass plate, It is summarized as "cut using a laser beam." Here, laser-induced glass cutting is used. a desired temperature profile on the glass surface and within the glass thickness for the separation process This involves the use of a mid-infrared (mid-IR) laser to generate Laser 5. mid-IR radiation to achieve a desired penetration depth through the thickness of the glass The ability to adjust the laser wavelength provides flexibility in the separation process. Mid-IR Wavelength control within this range, for example, approximately depending on the thickness of the glass. Changing the depth of the heating zone in the glass from μm to approximately 30 cm. It provides the possibility of controlling the depth of the heating zone in the glass, with 10 different options. It allows for different heating profiles for laser separation processes. Document number WO2022253064A1, “A separation for laser-cut glass” method and separation device. The method includes the following steps: The first step is to put the glass (18) After cutting the desired closed shape with a laser, a closed 15 is cut in the glass (18). Heating the outer ring region of the orbit (20) (19), a closed cut in the glass (18) heating the outer region of the orbit (19) (22) or a closed cut in the glass (18) heating the outer region (22) and the inner ring region (21) of the orbit (19) and in the glass (18) to cool the inner ring region (21) of a cut closed orbit (19) so that the glass (18) A crack formed by cutting penetrates inwards. Heating and cooling 20 The combination leads to an increasing temperature gradient in the cutting region of the glass (18). by opening it, the cracks formed during the laser cutting process can quickly penetrate inside. It encourages further cracking to form a wider crack, thus under the applied mechanical external forces, the thicker glass (18) It can be cut off.” This has been summarized as follows: 25 Document number WO2024079172A1, “This invention is for cutting glass sheets.” It relates to a laser cutting machine used and includes: the surface to be cut on. a work surface on which at least one glass plate is placed; that at least one glass plate to engrave on it, the first laser beam and 30 at the said engraving point producing a second laser beam to make a precise cut in at least one glass plate. at least one laser generator (10); where at least one laser generator (10) is in question, movement on the working surface according to three perpendicular Cartesian axes 3 It can be made that at least one laser generator (10) is involved in the study. When moved across its surface, the first laser beam and the second laser beam together It obtains at least one cut in at least one glass plate; at least three linear cuts. The actuator (5a, 5b, 5c, 5d) is directly connected to at least one of the laser generators (10). or acts indirectly and is essentially perpendicular to the work surface in question, with a related 5 It operates according to the axis of motion; thus, at least three linear actuators in question (5a, 5b, 5c, 5d) Modifying the extension along the relevant axis of motion, at least one laser generator (10) and the first laser beam and the second laser It changes the angle of the light beam relative to the working surface in question; therefore, in use, The first laser beam and the second laser beam make an oblique cutting motion on the work surface in question. 10 Depending on its surface, at least one cut is obtained on at least one glass plate in question. It allows for..." as summarized.
