Definitions
- the invention relates to a ner driving for the laser-assisted introduction of metal ions by ion exchange and diffusion and for coloring glass (see, for example, III, 121).
- glass has mostly been labeled externally for identification or advertising purposes. As is known, this is done by labeling on the surface of the glass or by processing the glass surface.
- Plastic foils that have been pre-cut are usually glued to the glass surface; Another method for externally applying lettering to glass surfaces is realized by screen printing.
- the glued foils as well as the applied screen printing are subject to all weather influences as well as mechanical influences from the outside.
- the known ner processes for labeling glass surfaces by processing the glass surface describe ner processes such as etching or engraving of the glass surfaces.
- the glass surface coated with a diffusion color is locally melted by means of infrared laser radiation and the diffusion color is convectively mixed into the melted glass areas.
- color ions diffuse from the mixed-in diffusion color into the surrounding glass "... so that they leave an even and permanent trace of color for normal-sighted eyes ".
- the glass or certain sub-areas thereof are heated by absorption of those focused on the glass surface
- the second is due to the advantageous properties typical of the laser material processing tool, such as versatility and speed To carry out the process step in accordance with the solutions representing the state of the art with little effort and to integrate it very well into production processes.
- the first process step of ion exchange is much more complex to implement due to the complicated technology and the considerably longer process times compared to the second process step.
- This second process step is also difficult to integrate into production processes.
- Another method of creating markings, inscriptions and decorations directly under the glass surface using diffusion colors is the use of foils printed with diffusion color in the form of fonts, symbols or images, and how decals are glued to the glass to be labeled.
- the foils printed in this way are therefore also called decals.
- Diffusion colors and decals are described in technical information 131: “Diffusion colors - also called yellow or silver etching - are silver-containing preparations that give the decorated glass a yellow to dark brown transparent color. ... diffusion colors can be transferred to the object to be decorated using a decal. "Another product example are the TRANSCOLOR decals of H. Albert OHG 141. After gluing, the glasses are heated to temperatures up to the transformation temperature T of the glass in order to color the diffusion of the metal ions into the glass, their subsequent reduction to atoms and finally the aggregation of the atoms To cause metal particles and thus the formation of the markings or decorations in the glass.
- the annealing process must be carried out over several hours to produce strong colors.
- the tempering process is often divided into several shorter successive tempering steps with the glass cooling in between.
- this labeling process can only achieve lower resolutions of the labels or decorations compared to the resolutions that can be achieved with laser-assisted interior labeling.
- the process of laser-assisted colored labeling on the inside and the process of tempering glasses with decals differ in the basic process steps of ion exchange, reduction of metal ions and formation of metal particles, including the necessary heating of the glass in the locality.
- a so-called low-temperature ion exchange takes place globally, in a second locally limited heating step there is also a locally limited reduction of the metal ions and formation of the metal particles.
- the invention has for its object to develop a method for the laser-assisted entry of metal ions and for the color inside labeling of glass, which eliminates the disadvantages of the prior art.
- a special embodiment of the method according to the invention is that the local heating of the glass is carried out by means of laser radiation focused on the glass surface in such a way that only ion exchange and diffusion take place without subsequent reduction of the metal ions and their aggregation to metal particles.
- the labeling according to the invention also avoids the disadvantageous global warming of the glass. By avoiding any global warming processes, the new process achieves considerable energy savings compared to the other two labeling processes.
- the new process is characterized by simple technological feasibility and very good integrability in production processes. Its high flexibility is characterized by the fact that, due to the computer control of the laser beam, any, often changing, electronic typeface and image templates can be reproduced.
- the surface of the glass to be provided with a colored inscription can alternatively be coated with pickling pastes or diffusion paints without the use of decals using conventional methods such as painting or spraying.
- Another variant of the inscription method is that several successive inscriptions take place, in which the glass surface is covered with decals which are printed over the surface with pickling pastes or diffusion colors containing different metal ions. In this way, multi-colored lettering or decorations can be created.
- the new labeling process can be advantageously implemented with CO 2 laser radiation.
- the pixels can have a minimum diameter of 100 ⁇ m and a depth of less than 1 ⁇ m directly below the glass surface.
- Electronic font and image templates can be reproduced in the glass with high resolutions. Since the pixels are located in the glass, inscriptions and markings produced in this way are absolutely scratch-resistant, chemically as resistant as the glass itself and temperature-resistant to just below the transformation temperature T of the glass.
- the lettering or markings are also resistant to UV radiation.
- the glass surface glued in this way with the film is coated with a focused CO
- the laser-induced heating takes place according to a motif, which is available as a black and white bitmap file with a resolution of 600 dpi.
- the creation of the motif in the glass surface is carried out line by line by computer-controlled guidance of the laser beam using a commercially available one
- the laser-assisted local heating of the metal ions is used to introduce them
- the film residues are removed from the glass surface.
- the glass now contains this in its surface
- Invisible markings were successfully created with laser powers of less than 10 watts.
- local heating of the black dots on the motif is carried out in such a way that the formation of silver particles in the glass is induced and the glass is colored yellow to brown at these points.
- the surface of the glass now contains the motif in a resolution of 600 dpi. Colorings were successfully generated with laser powers of less than 20 watts.
