Description

  • Field of the invention
  • The present utility model relates to laser processing of non-metallic, transparent materials used in structural glass products designed for transportation, aerospace, construction, and also used in the manufacture of armored glasses, marine glasses, and the like. In particular, the utility model relates to a table for processing non-metallic, transparent materials by laser radiation, in particular for removing metallic coatings, for example low-emission coatings, and other coatings from the glass.
  • State of the art
  • Table structures for processing fragile, non-metallic, transparent materials by laser radiation are known from the prior art.
  • The most relevant state of the art is one in the EP 1864950 A1 discloses a device that removes a coating along the peripheral edges of a windowpane. The apparatus has a bench with a material that forms a cover layer for positioning a glass sheet to be processed such that the removed coating on the glass was directed upwardly toward the laser head, which removes the coating from the surface of the disk. In this technical solution, the energy of the laser beam is adjusted so that no secondary effect is caused in the glass or in the cover layer of the bank on which the disk is arranged. Therefore, the prior art provides for adjusting the energy of the laser beam; however, the cover layer does not scatter the laser radiation, either completely or partially, ie it does not act as a non-adherent, scattering cover layer. Consequently, there is no way to increase the energy of the laser beam without risking damaging the cover layer.
  • Presentation of the invention
  • The object of the present utility model is to provide a capping layer on a table surface to allow processing of non-metallic, transparent materials (low emission coating glass) by focused, pulsed laser radiation (having a wavelength of 300 nm to 3000 nm ) while eliminating damage to the layer, table top and surface of the glass article.
  • The object is achieved by a table for working non-metallic, transparent materials comprising a frame with a work surface formed thereon and at least one cover layer positioned on the work surface for positioning the machined material, the at least one cover layer being formed of a material that is in Depending on the type of laser radiation used for processing for laser radiation in the wavelength range of 300 nm to 3000 nm is transparent, and is an elastically flexible foam material having a closed cell structure and strong intermolecular bonds.
  • The technical effect provided by this combination of features is that in the course of processing a material, for example, removing a low-emission coating from a glass article, by a focused laser beam passing through the glass volume, the laser beam in the cap layer completely and partially at a low power density W / cm 2 is scattered. Therefore, the cover layer acts as a non-adherent, diffusing cover.
  • The term "closed cell structure" as used herein refers to a structure having cells that are completely closed by plastic. Cellular plastics can be present in two basic structures: closed-cell or open-cell. Closed-cell materials have individual cavities or cells that are completely enclosed by plastics, and gas transport through the cell walls occurs by diffusion (see "Handbook of Plastics, Elastomers, and Composites" by Charles A. Harper, The McGraw-Hill Companies, 2004, p. 87 ).
  • The material structure is essential for the present technical solution, because the air-filled, closed cells act in the physical sense as negative lenses with refractive index K = 1, at their interfaces, with the starting material having a refractive index K in the range of 1.4-1.5, the pulsed laser radiation depending on the thickness and the foaming multiplicity is completely or partially broken and scattered.
  • In addition, the cross-linked, closed cell structure, which forms a solid space framework with strong intermolecular bonds that ensure the strength of the cell walls, makes the material elastically flexible. The term "elastically flexible material" as used herein refers to a material that resumes its former shape after removal of stress. Such a material typically has strong intermolecular bonds, ie, outer electrons of atoms in the material form covalent bonds. It It is believed that the main difference between strong bonds and weak bonds is that covalent interactions occur when there is a substantial overlap between the electron clouds of the subsystems.
  • The term "non-metallic materials" also refers generally to materials having covalent bonds, which in effect precludes the presence of electron gas in the product and therefore, provides poor thermal and electrical conductivity properties. Another difference to metallic materials is a significantly lower density of non-metallic materials. Therefore, the density of plastics is half that of aluminum. Non-metallic materials include, but are not limited to, organic and inorganic polymers, various types of plastics, non-metallic composite materials, rubber, adhesives, sealants, graphite, inorganic glasses, and ceramics.
  • The term "transparent to laser radiation" is well known to those skilled in the art and means that the material exhibits transparency in the wavelength range corresponding to the type of laser radiation used for processing.
  • "Foam material" refers to a material having a foam or cell structure obtained by any foaming process, for example, by adding a foaming agent to polymers.
  • The elastically flexible foam material is preferably physically or chemically crosslinked. Methods for chemical and physical crosslinking are also well known to those skilled in the art.
  • In particular, the term "cross-linked" refers to polymers in which all chains of covalent bonds are linked together in a three-dimensional network (see FIG "Handbook of Plastics, Elastomers, and Composites" by Charles A. Harper, The McGraw-Hill Companies, 2004, p. 3 ).
  • Further, the elastically flexible foam material has a foaming multiplicity of 5 to 35. The "foaming multiplicity" is the ratio of the initial foam volume to the volume of blowing agent used to obtain the foam material.
  • The cover layer preferably has a residual stress of less than 4%, is non-toxic in the operating temperature range and does not emit substances harmful to humans.
  • The elastically flexible foam material of the cover layer preferably has a density of 20 kg / m 3 to 200 kg / m 3 and a residual stress of less than 4%.
  • An example of the elastically flexible foam material is Penolon.
  • The cover layer preferably has a thickness of 1 mm to 50 mm.
  • In one embodiment, the cover layer may be supported by an aluminum foil.
  • The material of the at least one covering layer for pulsed laser radiation in the wavelength range of 1030 nm-1120 nm and particularly preferably at 1070 nm is preferably transparent.
  • The table is preferably configured as a frame on which a work surface is formed, and preferably includes a system for generating an air cushion effect when the material is positioned, the system having air outlets in the table.
  • Brief description of the drawings
  • Other objects and advantages of the present technical solution will be apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings, wherein:
  • 1 schematically shows a laser processing system in which a table according to the present utility model can be used, and
  • 2 an enlarged view of a portion of a support surface of the table with a cover layer according to the present utility model is.
  • Detailed description of embodiments
  • As in 1 As shown, an apparatus for processing non-metallic, transparent materials by laser radiation has a table 1 for processing the materials by laser radiation on, which is a frame 2 (preferably, a strong steel structure) having a work surface formed thereon in the shape of a substantially rectangular plate. The work surface is the support for depositing a workpiece to be machined, eg, a glass sheet from which a low-emission coating is to be removed.
  • Like also in 1 As shown, the device has one on the frame 2 , cutting bridge mounted parallel to the short side of the frame, which is preferably a steel construction. The cutting bridge can be along the long side of the frame 2 be moved and carries a laser cutting head 3 which can be moved along the bridge by a drive (not shown). The laser cutting head 3 may have various embodiments and preferably comprises a focusing lens and a scanning unit. In this case, it can be perpendicular to the surface of the table 1 be raised and lowered.
  • The frame 2 can with means (not shown) for moving the machined material (glass) before and after the machining process (cutting) and for positioning the material on the table 1 be provided.
  • As in 2 shown, the frame points 2 Further, an upper plate 4 on, on the at least one cover layer 5 is provided for positioning the material. In one embodiment, an aluminum foil 6 arranged under the cover layer.
  • The plate 4 may also be adapted to provide the air cushion effect. In this case are air outlets 7 for compressed air, which is supplied to these outlets, so in a certain pattern in the plate 4 formed that friction between the glass and the plate 4 (especially on the sides where the disc is not covered by the cover layer) when the disc is positioned is avoided.
  • According to the present utility model, the at least one covering layer 5 formed of a material which is transparent to laser radiation in the wavelength range of 300nm-3000nm, depending on the type of laser radiation used for processing, and which is an elastically flexible foam material having a closed-cell structure and strong intermolecular bonds.
  • An example of this material is Penolon. However, the class of usable foamed plastics is extremely broad, and any material with the same basis (and produced under other names and trademarks) based on foamed polyethylene or copolymers thereof can be used.
  • For example, penoizole (heat-insulating carbamide foam) is also a promising material. This material shows low thermal conductivity (less than 0.04 W / mK), low density (10 kg / m 3 -15 kg / m 3 ), is easy to process, refractory, durable and resistant to microorganisms and most organic solvents.
  • Polyethylene foam may also be mentioned under thermal insulation foam polymers. Polyethylene foam is a resilient, flexible, porous and waterproof, chemically resistant and environmentally friendly material.
  • This group also includes: Teploy, Vilaterm, Penofleks, Stenofon, Azurizol. Each of these materials is a thermal insulator.
  • An example of a laser used for processing is an Ytterbium fiber laser with a wavelength of 1030 nm-1120 nm, a pulse duration of 70 ns-90 ns, a pulse repetition rate of 30 kHz-1000 kHz and an average power of 20 W-50 W. The wavelengths of about 1070 nm are preferred because they provide better absorption by the low emission coating and less absorption by glass.
  • The following is an example in which the present table is used for processing fragile, non-metallic, transparent materials by laser radiation.
  • The example of machining a material by laser radiation involves the removal of a low-emission coating of glass articles using an in-line 1 illustrated laser processing system.
  • Preferably, the method includes the following sequence of steps:
    First, a glass article with the low emission coating to be processed is turned up onto a cover layer 5 according to the present technical solution, wherein the disc is positioned on the air cushion (in the air layer) and by abutment elements;
    then a machining program is activated to a laser head 3 and the focused laser beam removes the low emission coating (which is not transparent to the laser radiation) from predetermined portions on the glass surface.
  • If necessary, the disc is scanned before being processed by a television system (depending on the complexity of the shape).
  • The speed of the laser beam is preferably 2 mm / sec-4,000 mm / sec at a power density of not less than W = 30 × 10 3 W / mm 2 , and the diameter of the heating spot is at least 20 μm. The cover layer 5 may withstand even "heavier" heating conditions, but these are not used in the described method, since the machined glass article in this case is strongly heated and thermal stresses may occur in it, which is unacceptable.
  • In the example above, the resulting product is glass with a hard (k) or soft (l) low emission coating from which is evaporated (ablated) a metallized layer or low emission coating which is exposed to a focused laser beam to perform process cuts and the coating material completely to achieve required for the glass article heat properties. After electrical contacts have been soldered to the beginning and end of a conductive path, a ready-to-use, electrically heated glass is then created, to which a voltage is applied, rated for a predetermined temperature and the area of the glass.
  • In addition to electrical heating, the hard and soft coating is used for its primary energy saving purpose, i. for the reflection of infrared rays inside and ultraviolet rays outside, reducing the heat loss in cold weather, and reducing the penetration of excessive heat in warmer weather.
  • The removal of a low emission coating is performed at locations calculated by a suitable program to permit the manufacture of glass products having heating parameters predetermined over the surface of the glass article, for a variety of applications, for structural optics, automobiles, aviation, bulletproof glass or electrically heatable architectural structures enable.
  • It will be apparent to those skilled in the art that the present invention is not limited to the embodiments described above, and that it may be modified within the scope of the claims set forth below. Where necessary, the distinguishing features described in connection with other distinguishing features may also be used separately.
