Abstract
Verfahren zur Reparatur von verformten oder defekten Oberflächen (Oberflächen mit einer „Delle”), insbesonders von Kraftfahrzeug-Karosserien. Dabei wird die Delle mittels eines aufgebrachten Formstückes konturgetreu ausgefüllt. Das Formstück wird durch dreidimensionale Berechnung bestimmt und mittels 3D-Drucker gefertigt, unter Verwendung eines geeigneten Druckmaterials. In die dreidimensionale Berechnung gehen die Ist-Kontur der Delle und die Soll-Kontur des beschädigten Karosseriebereiches und fertigungsbedingte Korrekturgrößen ein. Eine vorteilhafte Ausgestaltung ist die Herstellung der gewünschten Oberflächenqualität und -Farbe direkt beim 3D-Druckprozess. Kann dasdort nicht vollständig erreicht werden, so kann eine geeignete Nachbearbeitung des hergestellten Formstückes noch vor der Montage durchgeführt werden.Method for repairing deformed or defective surfaces (surfaces with a "dent"), in particular motor vehicle bodies. The dent is filled contour by means of an applied fitting. The molding is determined by three-dimensional calculation and manufactured by means of 3D printers, using a suitable printing material. In the three-dimensional calculation, the actual contour of the dent and the desired contour of the damaged body area and manufacturing-related correction values enter. An advantageous embodiment is the production of the desired surface quality and color directly in the 3D printing process. If this can not be achieved completely there, a suitable post-processing of the molded article produced can be carried out prior to assembly.
Description
Herkömmlicherweise werden kleinere und mittlere Blechschäden an Kraftfahrzeugen („Dellen”) ausgespachtelt, geschliffen und lackiert. Das sind mehrere Arbeitsschritte, und sie werden im Einzelfall sogar mehrfach ausgeführt. Das ist zeit- und damit auch kostenaufwendig, und kann im Einzelfall besonders aufwendig sein, je nachdem, wie sich der Verlauf der soll-Kontur im Bereich der beschädigten Stelle darstellt.Conventionally, small and medium-sized sheet metal damage to vehicles ("dents") are filled, sanded and painted. These are several work steps, and they are even executed several times in individual cases. This is time-consuming and thus costly, and can be particularly costly in individual cases, depending on how the course of the target contour in the area of the damaged area.
Aufgabe der vorliegenden Erfindung ist die Verbesserung des Reparaturverfahrens: genauer und/oder schneller und/oder kostengünstiger.Object of the present invention is the improvement of the repair process: more accurate and / or faster and / or cheaper.
Erfindungsgemäßer Lösungsansatz:Inventive Approach:
Anstatt wie bisher Füllmaterial auf der Delle aufzubringen und nach dem eventuell notwendigen Aushärtungsprozess zurechtzuschleifen, wird ein optimal konturiertes Füllstück auf die Delle gesetzt (geklebt oder verschraubt oder vernietet usw.), das mittels 3D-Drucker passgenau hergestellt wurde.Instead of applying filler material to the dent and grinding it down after the necessary curing process, an optimally contoured filler is placed on the dent (glued or screwed or riveted, etc.), which has been produced precisely using a 3D printer.
Dazu wird die Form der Delle dreidimensional gescannt (die „Unterseite”; z. B. mittels handelsüblichen 3D-Scannern oder Verwendung der Microsoft Kinect®). Durch rechnerischen Vergleich der Soll-Kontur der „Oberseite” (z. B. vom Fahrzeughersteller geliefert oder per 3D-Scan an einem unbeschädigten Muster ermittelt) mit der Ist-Kontur der Delle („Unterseite”) wird die dreidimensionale Kontur (Ausformung) des Füllstückes ermittelt. Eventuelle notwendige Konturkorrekturen werden eingerechnet (z. B. wegen der Dicke eines evtl. zur Montage verwendeten Klebstoffes auf der „Unterseite”, und/oder wegen Schrumpf- und Schwindmaßen).For this purpose, the shape of the dent is scanned three-dimensionally (the "bottom", eg using commercially available 3D scanners or using the Microsoft Kinect® ). By computational comparison of the desired contour of the "top" (eg, supplied by the vehicle manufacturer or determined by 3D scan on an undamaged pattern) with the actual contour of the dent ("bottom") is the three-dimensional contour (shape) of Filler determined. Any necessary contour corrections are included (eg due to the thickness of any adhesive used for mounting on the "underside", and / or due to shrinkage and shrinkage).
Stehen dann die 3D-Daten des Füllstückes fest (also seine räumliche Form), so wird es unter Verwendung eines geeigneten Druckmateriales am 3D-Drucker ausgedruckt. Das Druckmaterial kann je nach Anforderung variieren, oft wird es Kunststoff oder Metall sein.If the 3D data of the filler is then fixed (ie its spatial form), it is printed using a suitable printing material on the 3D printer. The print material can vary depending on the requirement, often it will be plastic or metal.
Schließlich kann das Füllstück mit der „Unterseite” auf die Delle aufgebracht und befestigt werden. Je nach Oberflächenanforderungen an die zu reparierende Stelle kann nachfolgend ein Finishing- und/oder Lackierprozess für die „Oberfläche” notwendig werden.Finally, the filler can be applied and fixed with the "bottom" on the dent. Depending on the surface requirements of the site to be repaired, a finishing and / or painting process for the "surface" may subsequently be necessary.
Eine erfindungsgemäße Weiterentwicklung/Ausgestaltung ist es, das Füllstück bereits beim Druckprozess in der benötigten Oberflächenfarbe herzustellen (passende Einfärbung des verwendeten Druckmaterials oder entsprechende Lackierung nach dem Druck, aber noch vor der Montage).An inventive development / refinement is to produce the filler already in the printing process in the required surface color (suitable coloring of the printing material used or appropriate painting after printing, but even before installation).
