Description
Die Erfindung betrifft eine Vorrichtung zum Beschichten überlanger flächenhafter Substrate, insbesondere Glasscheiben in einer Vakuum-Beschichtungsanlage.The invention relates to a device for coating overlong sheet-like substrates, in particular glass sheets in a vacuum coating system.
Die magnetfeldunterstützte Kathodenzerstäubung (Magnetron Sputtering) hat Eingang gefunden in viele Bereichen der modernen Oberflächentechnik. Ausgehend von Anwendungen in der Halbleiterelektronik ist die magnetfeldunterstützte Kathodenzerstäubung heute als industrielles Beschichtungsverfahren für Architekturglas, Flachbildschirme, Brillengläser, Bandmaterialien, Werkzeug, dekorative Gegenstände und funktionelle Bauteile etabliert. Die größten Vakuum-Beschichtungsanlagen, und damit oftmals auch die Anlagen mit dem höchsten Energiebedarf, sind die typischen horizontalen In-Line-Anlagen für die Architekturglas-Beschichtung. Im Laufe der Entwicklung haben sich Standardscheibenformate sowohl für die Beschichtung als auch für die weitere Verarbeitung und Logistik etabliert. Die Beschichtungsanlagen werden in der Regel für die Standardscheibenformate (z. B. Länge 6,00 m × Breite 3,21 m) ausgelegt. Zusätzlich werden in den Beschichtungsanlagen übergroße Scheibenformate beschichtet. Der prozentuale Anteil diese übergroßen Scheibenformate am gesamten Produktionsvolumen ist eher gering, so das mittels technischer und steuerungstechnischer Anpassungen der Anlage Möglichkeiten geschaffen werden, auch überlange Scheibenformate (z. B. Länge 12,00 m × Breite 3,21 m) ohne nennenswerte Investitionen zu beschichten. Gemäß dem Stand der Technik werden spezifische Anordnungen von Vakuumpumpen bzw. Vakuumpumpständen und auch Strömungsblenden innerhalb von Vakuumkammern benutzt, um eine Beschichtungsanlage sowohl für Standardscheiben als auch für überlange Scheibenformate benutzen.Magnetic field assisted sputtering (magnetron sputtering) has found its way into many areas of modern surface technology. Starting from applications in semiconductor electronics, magnetic field assisted sputtering is established today as an industrial coating method for architectural glass, flat screens, spectacle lenses, strip materials, tools, decorative objects and functional components. The largest vacuum coating systems, and thus often the most energy-demanding systems, are the typical horizontal in-line systems for architectural glass coating. In the course of development, standard disc formats have become established both for coating and for further processing and logistics. The coating systems are usually designed for the standard disc formats (eg length 6.00 m × width 3.21 m). In addition, oversized disc formats are coated in the coating equipment. The percentage of these oversized disc formats in the total production volume is rather low, so that possibilities are created by means of technical and control-technical adaptations of the system, even overlong disc formats (eg length 12.00 m × width 3.21 m) without significant investments coat. In the prior art, specific arrangements of vacuum pumps and also flow diaphragms within vacuum chambers are used to utilize a coating equipment for both standard and long wafer formats.
