Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Beschichten von sekundärbeschichteten Lichtwellenleitern (LWL) in einem kontinuierlich laufenden Prozeß. Nach der umfangreichen Modifizierung einer vorhandenen Anlage zum Färben von LWL, hat sich die Möglichkeit zur Anwendung verschiedener Methoden zur Beschichtung der LWL-Fasern ergeben.The present invention relates to a method for coating secondary-coated optical fibers (LWL) in a continuously running Process. After extensive modification of an existing dyeing system of LWL, has the possibility to use different methods for LWL fibers are coated.
Durch die Anwendung einer vom Erfinder gebauten Vorrichtung ist das Aufbringen einer oder mehrerer, blasenfreier Beschichtungen möglich.By using a device built by the inventor, the application of a or several, bubble-free coatings possible.
Es werden kontinuierlich, auf der gesamten Länge des LWL-Bändchens, Beschichtungen aufgetragen. Die Stabilität des Bändchens wird durch das Aufbringen einer zusätzlichen Außenschicht aus Fasern und ultraviolett härtbarem Tränkmaterial wesentlich erhöht. Durch eine weitere, jedoch extrudierte Umhüllung, kann dieses Faserbändchen als fertiges Kabel Verwendung finden (siehe Anlage 1).Coatings are applied continuously along the entire length of the optical fiber ribbon applied. The stability of the ribbon is ensured by the application of an additional one Outer layer made of fibers and ultraviolet curable impregnation material significantly increased. With a further, but extruded sheath, this fiber ribbon can be finished Find cables (see Appendix 1).
Die aufgetragenen, strahlungshärtbaren Beschichtungen, deren Konsistenz weich, mittel oder hart sein können, werden als Puffer für die Lichtwellenleiter benutzt.The applied, radiation-curable coatings, whose consistency is soft, medium or can be hard are used as buffers for the optical fibers.
In einem weiteren Prozeßsegment werden die verschiedenen Beschichtungen, sowohl Silicone oder auch Harze mit mehreren UV-Härteeinrichtungen bei hoher Geschwindigkeit ausgehärtet. Bei diesem Faserbändchen können verschiedene optische Fasern, Singlemode oder Multimode, gefärbt oder ungefärbt zur Anwendung kommen.In another process segment, the different coatings, both Silicones or resins with multiple UV curing devices at high speed hardened. This fiber ribbon can use different optical fibers, single mode or multimode, colored or uncolored.
Es ist zusätzlich möglich, durch das Einbringen von einem oder mehreren nichtmetallischen Zugentlastungselementen die Verwendung dieses Faserbbändchens als Kabel zu erreichen.It is also possible to introduce one or more non-metallic strain relief elements the use of this ribbon as Cable to reach.
Die Benutzung spezieller Formgebungseinheiten ermöglicht es kundenspezifische lineare Matrixprofile herzustellen.The use of special shaping units enables customer-specific linear To produce matrix profiles.
Das LWL-Bändchen durchläuft in gesamter genannter Faserlänge horizontal die Anlage. Es ist möglich, durch Variation der Temperatur des Matrixmaterials, die für den Beschichtungsprozeß optimale Viskosität des Beschichtungsmaterials einzustellen. Die Härtungskammern sind permanent mit UV-Licht durchstrahlt, innen verspiegelt, wobei die aufgetragene Beschichtung innerhalb kürzester Zeit aushärtet. The fiber optic ribbon runs horizontally through the entire length of the fiber. It is possible, by varying the temperature of the matrix material, for the Coating process to set the optimum viscosity of the coating material. The curing chambers are permanently irradiated with UV light, mirrored on the inside, the applied coating hardens within a very short time.
Je nach Beschichtungsmaterial, Schichtdicke und Ziehgeschwindigkeit können, in unterschiedlichen Variationen mehrere unterschiedliche UV-Lampen programmgesteuert kombiniert werden.Depending on the coating material, layer thickness and drawing speed, in different variations several different UV lamps under program control be combined.
Im Anschluß daran werden in einem Apparatursegment mit Hilfe von Messeinrichtungen die Abmessungen des bearbeiteten LWL-Bändchens gemessen.Subsequently, in an apparatus segment with the help of measuring devices the dimensions of the processed optical fiber ribbon measured.
Bekannt ist die Abhängigkeit der Schichtdicke von der Ziehgeschwindigkeit der Faser durch ein Beschichtungsbad. Die Ziehgeschwindigkeit des Faserbändchens wird in Abhängigkeit der Viskosität des Matrixmaterials, des Matrixaufbaus, der Matrixgröße und der Anzahl der Härtungseinrichtungen gewählt. Diese Härtungseinrichtungen sind gekennzeichnet durch ihre verschiedenen Strahlerleistungen, Strahlerarten und Strahlerdimensionen.The dependence of the layer thickness on the drawing speed of the fiber is known through a coating bath. The pulling speed of the fiber ribbon is in Dependence of the viscosity of the matrix material, the matrix structure, the matrix size and the number of hardening devices selected. These hardening devices are characterized by their different lamp outputs, lamp types and Spotlight dimensions.
Zeitlich parallel erfolgt eine kontinuierliche Protokollierung folgender Daten: Datum, Uhrzeit, Abmessungen des LWL-Bändchens, Mittelwert, Standardabweichung, Faserlänge und Bearbeitungsnummer.The following data is continuously logged in parallel: Date, time, dimensions of the fiber optic ribbon, mean value, standard deviation, Fiber length and processing number.
Die Protokollierung erfolgt im On-Line Betrieb und kann nach Belieben über einen angeschlossenen Drucker als Produktionsprotokoll ausgedruckt werden. Erzielt wird eine ständige Kontrolle der Fertigungsqualität und der wichtigsten Produktparameter, sowie die größtmögliche Fertigungstransparenz für den Kunden.The logging is done in online mode and can be done via a connected printer can be printed out as a production report. A constant control of the manufacturing quality and the most important ones is achieved Product parameters, as well as the greatest possible manufacturing transparency for the customer.
