- the invention is useful for improving the cleanability or fouling tendency of components of a paint robot or handling robot (e.g., door opener, hood opener).
- the invention is also suitable for reducing the tendency to fouling or for improving the cleanability of components of a paint booth, such as covers, gratings, conveyors, windows, wall panels or exhaust ducts.

Description
Die Erfindung betrifft ein Lackieranlagenbauteil, insbesondere einen Glockenteller für einen Rotationszerstäuber, gemäß dem Oberbegriff des Anspruchs 1. Weiterhin umfasst die Erfindung ein entsprechendes Herstellungsverfahren.The invention relates to a Lackieranlagenbauteil, in particular a bell cup for a rotary atomizer, according to the preamble of
Zur Lackierung von Kraftfahrzeugkarosseriebauteilen werden üblicherweise Rotationszerstäuber eingesetzt, die als Applikationselement einen rotierenden Glockenteller aufweisen. Problematisch hierbei ist die Tatsache, dass der Glockenteller im Lackierbetrieb sowohl an Außenflächen (z.B. Mantelfläche) als auch an Innenflächen (z.B. Überströmfläche) stark mit dem applizierten Lack verunreinigt wird, wobei der Lack teilweise sehr stark an der Oberfläche des Glockentellers anhaftet. Bei einem Beschichtungsmittelwechsel muss deshalb eine relativ große Menge an Spülmittel verwendet werden, um den Glockenteller von den anhaftenden Resten des alten Beschichtungsmittels zu reinigen, wofür auch relativ viel Zeit erforderlich ist. Dies gilt auch für das sogenannte Kurzspülen, das zwischen der Beschichtung einzelner Beschichtungsobjekte (z.B. Kraftfahrzeugkarosserien) durchgeführt wird. Nachteilig an den herkömmlichen Glockentellern ist also die Verschmutzungsneigung und die unbefriedigende Reinigungsfähigkeit.For painting automotive body components usually rotary atomizers are used, which have a rotating bell cup as the application element. A problem here is the fact that the bell cup is heavily contaminated with the applied paint both on outer surfaces (for example, lateral surface) and on inner surfaces (for example overflow surface) in the painting operation, the paint partially adhering very strongly to the surface of the bell cup. In the case of a coating agent change, therefore, a relatively large amount of rinsing agent must be used to clean the bell cup from the adhering residues of the old coating agent, which also takes a relatively long time. This also applies to so-called short rinsing, which is carried out between the coating of individual coating objects (for example motor vehicle bodies). A disadvantage of the conventional bell plates so the tendency to fouling and unsatisfactory cleaning ability.
Darüber hinaus unterliegen die Oberflächen, insbesondere die Überströmflächen, der herkömmlichen Glockenteller einem Verschleiß durch Korrosion und/oder Abrasion, wodurch die Oberflächenrauhigkeit erhöht wird, was wiederum die Anforderungen an die Reinigung des Glockentellers erhöht.In addition, the surfaces, in particular the overflow surfaces, of the conventional bell cup are subject to wear by corrosion and / or abrasion, whereby the surface roughness is increased, which in turn increases the requirements for cleaning the bell cup.

Der Erfindung liegt deshalb die Aufgabe zugrunde, die Verschmutzungsneigung eines Glockentellers zu verringern und/oder die Reinigungsfähigkeit des Glockentellers zu verbessern.The invention is therefore based on the object to reduce the tendency to foul a bell cup and / or to improve the cleanability of the bell cup.
Diese Aufgabe wird durch einen erfindungsgemäßen Glockenteller gemäß dem Hauptanspruch gelöst.This object is achieved by a bell plate according to the invention according to the main claim.
Im Rahmen der Erfindung ist vorgesehen, dass ein Lackieranlagenbauteil (z.B. Glockenteller) eine Oberflächenschicht aufweist, welche die Verschmutzungsneigung verringert und/oder die Reinigungsfähigkeit verbessert.In the context of the invention it is provided that a Lackieranlagenbauteil (eg bell cup) has a surface layer which reduces the tendency to fouling and / or improves the cleaning ability.
Die Erfindung sieht nun vor, dass die Oberflächenschicht durch das Verfahren der Ionenimplantation hergestellt wird.
Der Grundkörper selbst kann im Rahmen der Erfindung beispielsweise aus Aluminium oder einer Aluminiumlegierung, Titan, Stahl, Edelstahl, Buntmetall (Kupfer und dessen Legierungen), Keramik, Kunststoff oder einer Kombination dieser Materialien bestehen.
Die Oberflächenschicht kann im Rahmen der Erfindung Oxide, Nitride und/oder Karbide enthalten, wobei sich beispielsweise Bor, Molybdän, Tantal, Niob, Vanadium, Zirkonium, Silizium, Chrom, Titan, Kohlenstoff, Nickel und Fluorverbindungen als (Basis-) Materialien für die Oberflächenschicht eignen.The invention now provides that the surface layer is produced by the method of ion implantation.
The main body itself may in the context of the invention, for example, made of aluminum or an aluminum alloy, titanium, steel, stainless steel, non-ferrous metal (copper and its alloys), ceramic, plastic or a combination of these materials.
The surface layer may in the context of the invention contain oxides, nitrides and / or carbides, for example, boron, molybdenum, tantalum, niobium, vanadium, zirconium, silicon, chromium, titanium, carbon, nickel and fluorine compounds as (base) materials for the Surface layer are suitable.
In einem bevorzugten Ausführungsbeispiel der Erfindung besteht die Oberflächenschicht aus einem Material auf Basis von Si-O, Si-OH oder silizium-organischer Verbindungen, insbesondere in Form einer Nanoschicht, wie sie noch detailliert beschrieben wird.
Darüber hinaus ist zu bemerken, dass die Oberflächenschicht vorzugsweise Metalloxide, Metallnitride oder metallorganische Verbindung enthält.
Weiterhin ist zu erwähnen, dass die Oberflächenschicht wahlweise aus einem organischen, insbesondere metall-organischen Material oder aus einem anorganischen Material bestehen kann. Je nach dem zu verwendenden Beschichtungsmittel kann die Oberflächenschicht entweder hydrophil oder hydrophob sein. Eine hydrophile Oberflächenschicht zeichnet sich durch einen Kontaktwinkel gegenüber Wasser aus, der kleiner ist als 90°, 45°, 20°, 10°, 8° oder sogar kleiner als 6°. Darüber hinaus kann die Oberflächenschicht sogar superhydrophil sein, wobei sich die Oberflächenschicht dann durch einen Kontaktwinkel gegenüber Wasser von weniger als 5°, 3°, 2° oder sogar weniger als 1° auszeichnet. Bei einer hydrophoben Oberflächenschicht ist der Kontaktwinkel gegenüber Wasser dagegen vorzugsweise größer als 90°, 110°, 130° oder 150°. Im Rahmen der Erfindung besteht sogar die Möglichkeit, dass die Oberflächenschicht superhydrophob ist, wobei der Kontaktwinkel gegenüber Wasser größer ist als 160°, 180°, 200° oder sogar 220°.
Weiterhin besteht im Rahmen der Erfindung die Möglichkeit, dass die Oberflächenschicht eine sogenannte Nanoschicht ist, die eine Schichtdicke aufweist, die im Nanometerbereich liegt.
Weiterhin besteht im Rahmen der Erfindung die Möglichkeit, dass die Oberflächenschicht eine Mikrostrukturierung aufweist, um die Verschmutzungsneigung zu verringern. Beispielsweise offenbart
Darüber hinaus kann die erfindungsgemäße Oberflächenschicht eine weitere technische Funktion erfüllen, indem die Oberflächenschicht beispielsweise verschleißmindernd ist, was an sich aus der bereits eingangs zitierten Patentanmeldung
In einer Variante der Erfindung bestehen der Grundkörper und die Oberflächenschicht aus demselben Ausgangsmaterial, wobei die Materialeigenschaften der Oberflächenschicht gezielt verändert sind, um die Verschmutzungsneigung des Lackieranlagenbauteils zu verringern und/oder die Reinigungsfähigkeit zu verbessern.In a preferred embodiment of the invention, the surface layer consists of a material based on Si-O, Si-OH or silicon-organic compounds, in particular in the form of a nano-layer, as will be described in detail.
In addition, it should be noted that the surface layer preferably contains metal oxides, metal nitrides or organometallic compound.
It should also be mentioned that the surface layer may optionally consist of an organic, in particular metal-organic material or of an inorganic material. Depending on the coating agent to be used, the surface layer may be either hydrophilic or hydrophobic. A hydrophilic surface layer is characterized by a contact angle with respect to water which is less than 90 °, 45 °, 20 °, 10 °, 8 ° or even less than 6 °. In addition, the surface layer may even be superhydrophilic, with the surface layer then being characterized by a contact angle with water of less than 5 °, 3 °, 2 °, or even less than 1 °. By contrast, in the case of a hydrophobic surface layer, the contact angle with respect to water is preferably greater than 90 °, 110 °, 130 ° or 150 °. In the context of the invention, there is even the possibility that the surface layer is superhydrophobic, wherein the contact angle with respect to water is greater than 160 °, 180 °, 200 ° or even 220 °.
Furthermore, within the scope of the invention, the possibility exists that the surface layer is a so-called nanolayer, which has a layer thickness which is in the nanometer range.
Furthermore, it is within the scope of the invention, the possibility that the surface layer has a microstructuring in order to reduce the tendency to fouling. For example disclosed
In addition, the surface layer according to the invention can fulfill a further technical function in that the surface layer is, for example, wear-reducing, which in itself results from the patent application cited above
In a variant of the invention, the main body and the surface layer consist of the same starting material, wherein the material properties of the surface layer are selectively changed in order to reduce the tendency of the painting component to become soiled reduce and / or improve cleanability.
Zur Erzielung spezieller Oberflächenschichten kann es im Rahmen der Erfindung sinnvoll sein, mehrere übereinander liegende Teilschichten mit unterschiedlichen Materialeigenschaften aufzubringen, wobei sich die übereinander liegenden Teilschichten beispielsweise hinsichtlich Duktilität, Korrosionsbeständigkeit oder Verschleißwiderstand unterscheiden können.
Weiterhin besteht im Rahmen der Erfindung die Möglichkeit, dass die Oberflächenschicht mehrere Bereiche aufweist, die voneinander getrennt sind und unterschiedliche Eigenschaften aufweisen. In einem mechanisch stark belasteten Bereich kann die Oberflächenschicht beispielsweise stärker auf eine möglichst große Abriebfestigkeit hin optimiert werden, wohingegen die gute Reinigungsfähigkeit an derartigen Stellen eine geringere Priorität genießt. In Oberflächenbereichen, die dem Lack stark ausgesetzt und darüber hinaus nur schlecht zugänglich sind, kann die Oberflächenschicht dagegen vorrangig auf eine möglichst geringe Verschmutzungsneigung hin optimiert werden, wohingegen die Abriebfestigkeit in diesen Bereichen nur eine geringere Priorität genießt.
Ferner ist zu erwähnen, dass die Oberflächenschicht aus einem Material mit einer hohen, mittleren oder geringen Grenzflächenreibung bestehen kann.
Das Gleiche gilt sinngemäß auch für die Benetzbarkeit der Oberflächenschicht, die wahlweise aus einem Material mit einer sehr guten, guten oder geringen/schlechten Benetzbarkeit bestehen kann.
Auch hinsichtlich der Duktilität bestehen im Rahmen der Erfindung verschiedene Möglichkeiten, die je nach Anwendungszweck ausgewählt werden können. Beispielsweise kann die Oberflächenschicht aus einem Material mit einer hohen Duktilität bestehen, insbesondere mit einer Bruchdehnung von mehr als 5% oder 10%. Alternativ besteht jedoch die Möglichkeit, dass die Oberflächenschicht aus einem Material mit einer mittleren Duktilität besteht, insbesondere mit einer Bruchdehnung zwischen 0,5 und 5%. Ferner besteht auch die Möglichkeit, dass die Oberflächenschicht aus einem Material mit einer geringen Duktilität besteht, insbesondere mit einer Bruchdehnung von weniger als 0,5%, 0,3% oder 0,1%.To achieve special surface layers, it may be useful in the context of the invention to apply a plurality of sublayers lying one above the other with different material properties, wherein the sublayers lying one above the other are present For example, with regard to ductility, corrosion resistance or wear resistance can differ.
Furthermore, it is within the scope of the invention, the possibility that the surface layer has a plurality of areas which are separated from each other and have different properties. For example, in a mechanically heavily loaded area, the surface layer can be more optimized for the greatest possible abrasion resistance, whereas the good cleanability at such sites is less of a priority. On the other hand, in surface areas which are strongly exposed to the paint and, moreover, poorly accessible, the surface layer can be optimized for the lowest possible tendency to become soiled, whereas the abrasion resistance in these areas is given only a lower priority.
It should also be mentioned that the surface layer may consist of a material with a high, medium or low surface friction.
The same applies mutatis mutandis to the wettability of the surface layer, which may optionally consist of a material with a very good, good or low / poor wettability.
Also in terms of ductility exist within the scope of the invention, various options that can be selected depending on the application. For example, the surface layer may consist of a material with a high ductility, in particular with an elongation at break of more than 5% or 10%. Alternatively, however, it is possible that the surface layer of a material with a middle Ductility, in particular with an elongation at break between 0.5 and 5%. Furthermore, there is also the possibility that the surface layer consists of a material with a low ductility, in particular with an elongation at break of less than 0.5%, 0.3% or 0.1%.
Darüber hinaus kann die Oberflächenschicht aus einem Material mit einer großen Rauheit (z.B. Rz>50pm), einer mittleren Rauheit (z.B. Rz=10µm-50µm) oder einer geringen Rauheit (z.B. Rz<10µm) bestehen.In addition, the surface layer may be made of a material having a large roughness (e.g., Rz> 50pm), average roughness (e.g., Rz = 10μm-50μm), or low roughness (e.g., Rz <10μm).
Auch hinsichtlich der Abriebfestigkeit bestehen verschiedene Möglichkeiten, so dass die Oberflächenschicht wahlweise aus einem Material mit einer hohen, mittleren oder geringen Abriebfestigkeit bestehen kann.Also in terms of abrasion resistance, there are various possibilities, so that the surface layer can optionally consist of a material with a high, medium or low abrasion resistance.
Ferner bestehen auch hinsichtlich der Korrosionsbeständigkeit der Oberflächenschicht je nach Anwendungszweck verschiedene Möglichkeiten, so dass die Oberflächenschicht wahlweise aus einem Material mit einer großen, mittleren oder kleinen Korrosionsbeständigkeit bestehen kann.Furthermore, there are also various possibilities with regard to the corrosion resistance of the surface layer, depending on the application, so that the surface layer can optionally consist of a material with a high, medium or small corrosion resistance.
Die Korrosionsbeständigkeit ist insbesondere dann wichtig, wenn das Lackieranlagenbauteil (z.B. Glockenteller) aus Buntmetall (Kupfer und dessen Legierungen) besteht, da Buntmetalle auch in Verbindung mit vollentsalztem Wasser (VE-Wasser) korrodieren. Dies ist wichtig, weil VE-Wasser in Wasserlacken und Wasserspülmittel enthalten ist, so dass Glockenteller aus Buntmetallen mit einer korrosionsbeständigen Oberflächenschicht überzogen werden müssen.Corrosion resistance is particularly important when the paint shop equipment (e.g., bell cup) is made of non-ferrous metal (copper and its alloys) because non-ferrous metals also corrode in combination with demineralized water (DI water). This is important because demineralised water is contained in water-based paints and water-based detergents, so that non-ferrous metal dish plates must be coated with a corrosion-resistant surface layer.
Die vorstehend genannten Möglichkeiten der Materialeigenschaften können auch gezielt miteinander kombiniert werden, um bestimmte Eigenschaften zu erreichen.The abovementioned possibilities of material properties can also be combined in a targeted manner in order to achieve certain properties.
Für eine möglichst feine Zerstäubung des Beschichtungsmittels ist es beispielsweise vorteilhaft, folgende Materialeigenschaften der Oberflächenschicht miteinander zu kombinieren: Geringe Grenzflächenreibung, geringe Benetzbarkeit, hohe Duktilität, geringe Rauhigkeit, große Abriebfestigkeit und geringe Korrosionsbeständigkeit.For the finest possible atomization of the coating composition, it is advantageous, for example, to combine the following material properties of the surface layer: low interfacial friction, low wettability, high ductility, low roughness, high abrasion resistance and low corrosion resistance.
Zur Erreichung einer möglichst guten Reinigungsfähigkeit ist es dagegen vorteilhaft, folgende Materialeigenschaften miteinander zu kombinieren: Mittlere Grenzflächenreibung, hohe Benetzbarkeit, mittlere Duktilität, geringe Rauhigkeit, geringe Abriebfestigkeit und sehr gute Korrosionsbeständigkeit.In order to achieve the best possible cleaning ability, it is advantageous to combine the following material properties with each other: average interfacial friction, high wettability, average ductility, low roughness, low abrasion resistance and very good corrosion resistance.
Zur Erzielung eines Korrosionsschutzes von Aluminium ist es dagegen vorteilhaft, die folgenden Materialeigenschaften miteinander zu kombinieren: Mittlere Grenzflächenreibung, geringe Benetzbarkeit, hohe Duktilität, geringe Rauhigkeit, geringe Abriebfestigkeit und sehr gute Korrosionsbeständigkeit.In order to achieve corrosion protection of aluminum, however, it is advantageous to combine the following material properties: average interfacial friction, low wettability, high ductility, low roughness, low abrasion resistance and very good corrosion resistance.
In einer Variante der Erfindung überzieht die reinigungsoptimierende Oberflächenschicht die gesamte Oberfläche des Grundkörpers.In a variant of the invention, the cleaning-optimizing surface layer covers the entire surface of the base body.
In einer anderen Variante der Erfindung überzieht die reinigungsoptimierende Oberflächenschicht dagegen nur Außenflächen des Grundkörpers. Bei einem Glockenteller werden dann vorzugsweise die Mantelfläche und/oder die Rückseite des Grundkörpers mit der Oberflächenschicht überzogen.In another variant of the invention, however, the cleaning-optimizing surface layer covers only outer surfaces of the base body. In a bell cup, the outer surface and / or the rear side of the main body are then preferably coated with the surface layer.
In einer weiteren Variante der Erfindung wird dagegen nur eine Innenfläche des Grundkörpers mit der Oberflächenschicht überzogen. Bei einem Glockenteller kann es sich dabei beispielsweise um eine Überströmfläche handeln.In a further variant of the invention, however, only an inner surface of the base body is coated with the surface layer. For example, a bell cup may be an overflow surface.
In einer weiteren Variante der Erfindung überzieht die Oberflächenschicht die Oberfläche des Grundkörpers dagegen nur an Teilbereichen, die einer Optimierung der Reinigungseigenschaften bedürfen. Beispielsweise kann es sich hierbei um die Bereiche der Mantelfläche und der Überströmfläche handeln, die unmittelbar an die Absprühkante angrenzen.In a further variant of the invention, however, the surface layer covers the surface of the base body only on partial areas which require an optimization of the cleaning properties. For example, these may be the areas of the lateral surface and the overflow surface that are directly adjacent to the spray-off edge.
Das erfindungsgemäße Prinzip einer Optimierung der Verschmutzungsneigung bzw. der Reinigungsfähigkeit eignet sich nicht nur für Glockenteller von Rotationszerstäubern, sondern ist auch für andere lackführende Bauteile geeignet, wie beispielsweise Ventilgehäuse oder Ventilnadeln. Darüber hinaus eignet sich die Erfindung auch zur Verbesserung von sonstigen Lackieranlagenbauteilen, die im Betrieb mit einem Beschichtungsmittel in Kontakt kommen, wie beispielsweise Zerstäuber (z.B. Rotationszerstäuber), Roboterhandachsen, Roboterarme oder Flansche. Allgemein eignet sich die Erfindung zur Verbesserung der Reinigungsfähigkeit bzw. der Verschmutzungsneigung von Bauteilen eines Lackierroboters oder eines Handhabungsroboters (z.B. Türöffner, Haubenöffner). Schließlich eignet sich die Erfindung auch zur Verringerung der Verschmutzungsneigung bzw. zur Verbesserung der der Reinigungsfähigkeit von Bauteilen einer Lackierkabine, wie beispielsweise Abdeckungen, Gitterroste, Förderer, Fensterscheiben, Wandelemente oder Abluftkanäle.The inventive principle of optimizing the tendency to fouling or cleanability is not only suitable for bell plates of rotary atomizers, but is also suitable for other paint-carrying components, such as valve housing or valve needles. In addition, the invention is also useful for ameliorating other paint shop components that come in contact with a coating agent during use, such as atomizers (e.g., rotary atomizers), robotic hand axes, robotic arms, or flanges. In general, the invention is useful for improving the cleanability or fouling tendency of components of a paint robot or handling robot (e.g., door opener, hood opener). Finally, the invention is also suitable for reducing the tendency to fouling or for improving the cleanability of components of a paint booth, such as covers, gratings, conveyors, windows, wall panels or exhaust ducts.
Darüber hinaus ist zu erwähnen, dass die Erfindung nicht auf ein einzelnes Lackieranlagenbauteil (z.B. Glockenteller) beschränkt ist, das hinsichtlich seiner Verschmutzungsneigung bzw. Reinigungsfähigkeit optimiert ist. Vielmehr umfasst die Erfindung auch einen Rotationszerstäuber mit einem erfindungsgemäß optimierten Glockenteller sowie einen kompletten Lackierroboter mit einem derartigen Rotationszerstäuber.In addition, it should be noted that the invention is not limited to a single painting plant component (eg bell cup) which is optimized with regard to its tendency to fouling or cleaning capability. Rather, the invention also includes a rotary atomizer with an inventively optimized bell cup and a complete painting robot with such a rotary atomizer.
Schließlich umfasst die Erfindung auch ein Herstellungsverfahren zur Herstellung eines erfindungsgemäß optimierten Lackieranlagenbauteils (z.B. Glockenteller), wie bereits aus der vorstehenden Beschreibung hervorgeht.Finally, the invention also encompasses a production method for producing a coating plant component (for example bell cup) optimized according to the invention, as already apparent from the above description.
