Definitions

  • the present invention relates to a method for writing on or marking automobile glazing by means of a laser beam.
  • an ultraviolet laser beam can be used for which the intermediate layer of plastic material is opaque.
  • a pulsed laser beam is preferably used.
  • the known methods serve to mark laminated glazings in which the more absorbent layer is arranged, in the form of a polymer layer, between two sheets of glass.
  • an additional radiation absorbing layer may be provided, made of an organic material, for example of a light color.
  • the known methods are intended only for marking or writing a control or manufacturing number in the factory which manufactured the glazing.
  • the possibility of individually providing the glazing for a vehicle with a brand or an inscription directly related to this vehicle arouses considerable interest.
  • the registration of the vehicle chassis number or of another individual designation on the various glazing units may give the possibility of identifying stolen vehicles even if the chassis number, as such, has been removed or modified.
  • the invention proposes to apply the method of marking a glazing by a laser beam to a glazing already mounted by gluing in a bay of the vehicle body, this glazing being provided with an enamel strip, in particular with a peripheral strip forming a decorative frame, by focusing the laser beam which passes through at least part of the glazing on a part of the strip which is inaccessible for any subsequent modification.
  • a part of the enamel strip which is covered in particular by an element belonging to the glazing such as a sheet of glass or of plastic material, a plastic profile, or by an element used for the final assembly of the glazing, in particular a bead of glue or by any other element forming a body with the glazing and not detachable from said glazing mounted in the bodywork bay.
  • an element belonging to the glazing such as a sheet of glass or of plastic material, a plastic profile, or by an element used for the final assembly of the glazing, in particular a bead of glue or by any other element forming a body with the glazing and not detachable from said glazing mounted in the bodywork bay.
  • the part treated by laser radiation for marking the glazing is a part covered by the bead of glue used for the mounting of the glazing or by any other profile or cord integral with the glazing such as an extruded or encapsulated profile.
  • the part which can be marked is limited to the part described above.
  • the marking by the laser beam is carried out from the outside, through the glazing.
  • the glazing is a laminated glazing formed from at least one sheet of glass and at least one layer of plastic material
  • the enamel strip which can be marked according to the invention can not only be placed on the face of the sheet of glass oriented inward but also be arranged on an inner face of a glass sheet of the glazing.
  • the part to be marked can be located not only opposite the adhesive or profiled bead but also, it can be offset because in this arrangement the entire enamel strip is covered by a sheet of plastic material or by a sheet of glass and it is "inaccessible".
  • a pulsed YAG laser is preferably used.
  • the marking or the inscription can be adapted individually to the vehicle in question, which is not possible, for logistical reasons, when the glazing is not yet fitted in this vehicle.
  • the use in accordance with the invention takes advantage in particular of the fact that the glazings which are mounted by gluing in the vehicle are provided in their peripheral part in which the bead of mounting adhesive is located or opposite this bead, an opaque decorative frame for visible light and for ultraviolet, consisting of at least one layer of enamel.
  • the marking according to the invention therefore offers the decisive advantage that it is not possible to remove or modify the inscription without removing the glazing from the body. In this way, the same tamper-proof marking can therefore be obtained on a surface of the glazing, both for simple glazing and for laminated glazing.
  • the implementation of the method of the invention is also carried out in a known manner and with known means, by passing the laser beam over the glazing, by means of movable deflecting mirrors.
  • the control of the return mirrors in the X and Y directions is done using an appropriate process computer, as described in document DE 31 47 385 C2.
