Abstract

The plate (1) has an inner side, on which an inscription and/or ornamentation (5) is formed by a laser beam (3) and due to structural changes of the plate materials. The laser beam can be a red laser with a wave band of about 1064 nanometers or a green laser with a wave band of about 532 nanometers. The inner side of plate has transparent reflecting surfaces for incident light.

Description

Die Erfindung richtet sich auf eine mit einer Beschriftung und/oder mit Ornamenten versehene Glaskeramikscheibe.The Invention is directed to a with a label and / or ornate glass ceramic pane.

Glaskeramikscheiben werden beispielsweise als Schutz- und Aufsichtsfläche bei Feuerstellen für Privatwohnungen eingesetzt, d.h. insbesondere da, wo es zu sehr hohen thermischen Belastungen kommt, wobei gleichzeitig eine gute Transparenz der Scheibe erwünscht ist, d.h. eine Aufsicht auf die Feuerstelle soll jederzeit möglich sein.Ceramic discs become, for example, a protective and supervisory surface Fire pits for Private homes used, i. especially where it is too much high thermal loads, while a good Transparency of the disc desired is, i. a supervision of the fireplace should be possible at any time.

Es gibt Einsatzfälle derartiger Scheiben, in denen es erwünscht ist, diese z.B. mit einem Firmenlogo und/oder mit Ornamenten zum einen aus Hinweiszwecken, zum anderen aus Dekorationszwecken zu versehen, wobei es bekannt ist, Schablonen auf die Scheibenoberfläche zu legen und diese dann sandzustrahlen, was zum Teil aber nicht zu den gewünschten Erfolgen führt, zum anderen sind diese Scheiben für manche herkömmliche Behandlungsarten wenig geeignet, da es zu Zerstörungen kommen kann. Dies insbesondere, da Glaskeramiken als spröde Werkstoffe im technischen Sinne einzuordnen sind, in denen keinerlei Fließvorgänge stattfinden, so dass es bei Kontakt mit harten Werkoberflächen, etwa mit den Partikeln aus Sandstrahlvorgängen, zu Oberflächenverletzungen in Form kleiner Kerben und Risse kommen kann.It There are applications of such discs, in which it is desired, these e.g. with a Company logo and / or with ornaments for reference purposes, on the other for decoration purposes to provide, where it is known is to put stencils on the disk surface and then sandblast them, which leads but partly not to the desired success, for others are these slices for some conventional Types of treatment little suitable, since it can lead to destruction. This particular because glass ceramics as brittle Materials are to be classified in the technical sense, in which no Flow processes take place, making it in contact with hard work surfaces, such as with the particles from sandblasting processes, to surface injuries can come in the form of small nicks and cracks.

Eine andere Art der Beschriftung oder Verzierung der Oberflächen derartiger Scheiben ist wenig zufriedenstellend, etwa das Aufbringen von Aufdrucken mittels Lack od. dgl.A other type of labeling or decoration of the surfaces of such Slices is not very satisfactory, such as the application of imprints by means of lacquer od. Like.

Hier setzt die Erfindung an, deren Ziel es ist, Glaskeramikscheiben mit dauerhaften Beschriftungen zerstörungsfrei zu versehen.Here sets the invention, whose goal is to glass ceramic discs with permanent labels non-destructive to provide.

Diese Aufgabe wird mit einer Glaskeramikscheibe der eingangs bezeichneten Art dadurch gelöst, dass die Schriftzeichen und/oder die Ornamentik von im Scheibeninneren mittels eines Laserstrahles hervorgerufenen Strukturänderungen des Scheibenmateriales gebildet ist.These Task is with a glass ceramic disk referred to above Sort of solved by that the characters and / or ornamentation of inside the disc Structural changes caused by a laser beam the disc material is formed.

Es hat sich gezeigt, dass die Behandlung der Scheibe mit einer gezielten Laserbehandlung zur Änderung z.B. in der Scheibenmitte führt, wobei die dort auftretenden Strukturänderungen der Scheibe die Oberfläche nicht zerstören, so dass auch Schmutzpartikel in der Regel nicht eindringen können, so dass es nicht zu den die mechanischen Eigenschaften derartiger Scheiben störenden Risse und Sprünge kommen kann.It has been shown to treat the disc with a targeted Laser treatment to change e.g. in the middle of the disc, the structural changes of the disc occurring there do not affect the surface to destroy, so that dirt particles usually can not penetrate, so that it is not the mechanical properties of such discs disturbing Cracks and cracks can come.

Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Dabei kann es zweckmäßig sein, wenn die durch die Laserstrahlen hervorgerufenen Strukturänderungen im Inneren der ansonsten transparenten Glaskeramikscheibe Reflexionsflächen für einfallendes Licht aufweisen, wie dies die Erfindung ebenfalls vorsieht.refinements The invention will become apparent from the dependent claims. It may be appropriate when the structural changes caused by the laser beams Inside the otherwise transparent glass ceramic disc reflection surfaces for incident Have light, as the invention also provides.

Besonders vorteilhaft kann es darüber hinaus in weiterer Ausgestaltung sein, wenn die das optische Erscheinungsbild einer Schrift bzw. eines Ornamentes hervorrufenden Innenstrukturen von einem Rotlaser (Wellenbereich 1064 nm) oder einem Grünlaser (Wellenbereich 532 nm) hervorgerufen sind.Especially it can be advantageous over it Be in a further embodiment, if the visual appearance a script or an ornament causing interior structures from a red laser (wave range 1064 nm) or a green laser (waveband 532 nm).

Ein weiterer Vorteil der Erfindung besteht darin, dass es gleichgültig ist, welche Form die mit Schrift oder Ornamenten versehenen Bereiche der Glaskeramik aufweisen, etwa als ebene Flächen oder als gekrümmte Flächen ausgebildet sind.One Another advantage of the invention is that it does not matter which form the areas provided with writing or ornaments having the glass ceramic, formed approximately as flat surfaces or as curved surfaces are.

Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aufgrund der nachfolgenden Beschreibung sowie anhand der Zeichnung. Diese zeigt in stark vereinfachter Darstellung lediglich als Prinzipskizze einen Ausriss aus einer Glaskeramikscheibe mit einem mittels Laserstrahl eingebrachten Ornament.Further Features, details and advantages of the invention will become apparent the following description and with reference to the drawing. These shows in a simplistic representation only as a schematic diagram an eruption of a glass ceramic disc with a laser beam introduced ornament.

Eine allgemein mit 1 bezeichnete, nur im Ausriss dargestellte Glaskeramikscheibe wird im dargestellten Beispiel, wiederum nur symbolisch dargestellt, mittels einer Laserstrahlquelle 2 aus gepulstem Laser 3 beaufschlagt.A general with 1 designated, only in the form of a breakaway glass-ceramic disc is shown in the example shown, again only symbolically, by means of a laser beam source 2 from pulsed laser 3 applied.

Der Laser ist so eingestellt, dass er etwa in der mit 4 bezeichneten Mittelebene der Glaskeramikscheibe 1 Strukturänderungen in Form der gewünschten Beschriftung oder des gewünschten Ornamentes, allgemein mit 5 bezeichnet, auslöst, derart, dass einfallendes Licht dort entsprechend reflektiert wird und so die Ornamente bzw. die Beschriftung für den Menschen sichtbar erzeugt.The laser is set to be around in the 4 designated center plane of the glass ceramic disc 1 Structural changes in the form of the desired lettering or the desired ornament, generally with 5 designated, triggers, such that incident light is reflected there accordingly and so the ornaments or the caption produced visible to humans.
