Die DE 37 10 367 A1 beschreibt beispielsweise ein solches Verfahren für die Reinigung von metallischen Kleinteilen wie Schrauben, Presslingen, Drehteilen und dergleichen, bei dem Druckluft verwendet und das bei der Reinigung anfallende Öl abgeschieden und gegebenenfalls zurückgewonnen wird.Methods for de-oiling or degreasing of are known from the prior art Metal parts are known, in which these are acted upon with compressed air, for example. DE 37 10 367 A1 describes such a method for cleaning, for example of small metallic parts such as screws, compacts, turned parts and the like the compressed air used and the oil obtained during cleaning separated and possibly recovered.
Ein Verfahren zur Reinigung verschiedener Materialien, unter anderem auch von Metallen, bei dem diverse Reinigungsmedien verwendet werden ist in der DE 42 21 706 A1 beschrieben. Dort wird unter anderem auch die Verwendung von Heißluft als Reinigungsmedium vorgeschlagen, wobei jedoch zusätzlich eine mechanische Reinigung über Bürsten, Schaber oder dergleichen vorgesehen ist. Auch andere Reinigungsmedien wie Wasser, Säuren, Ultraschall werden in dieser Druckschrift vorgeschlagen. Es ist davon auszugehen, daß dieses Verfahren sehr unspezifisch ist, da zum einen sehr verschiedene zu reinigende Materialien aufgeführt werden und zum anderen sehr unterschiedliche Reinigungsmedien für eine kontaktlose Reinigung genannt werden und dazu noch eine mechanische Reinigung für notwendig gehalten wird.A process for cleaning various materials, including those from Metals, in which various cleaning media are used in the DE 42 21 706 A1 described. Among other things, the use of Hot air is proposed as a cleaning medium, but an additional one mechanical cleaning via brushes, scrapers or the like is provided. Also other cleaning media such as water, acids, ultrasound are described in this document suggested. It can be assumed that this method is very unspecific because on the one hand, very different materials to be cleaned are listed, and on the other other very different cleaning media for contactless cleaning be mentioned and also considered mechanical cleaning necessary becomes.
Ausgehend von dem genannten Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren zur Verfügung zu stellen, das für die kontaktlose Reinigung metallischer Oberflächen wie zum Beispiel von Blechteilen für den Karosseriebau spezifisch geeignet ist, um diese zu entölen beziehungsweise zu entfetten, bevor weitere nachfolgende Arbeitsschritte erfolgen können.Based on the prior art mentioned, the present invention is the Task to provide a method available for the contactless Cleaning metallic surfaces such as sheet metal parts for the Body construction is specifically suitable to de-oil or to degrease before further subsequent work steps can take place.
Die Lösung dieser Aufgabe liefert ein erfindungsgemäßes Verfahren der eingangs genannten Gattung mit den kennzeichnenden Merkmalen des Hauptanspruchs. An inventive method of the introduction provides the solution to this problem mentioned genus with the characterizing features of the main claim.
Erfindungsgemäß ist vorgesehen, daß die metallische Oberfläche ein für eine Fahrzeugkarosserie bestimmtes Blechteil ist und daß das Beaufschlagen dieses Blechteils mit dem Medium vor einem weiteren Verfahrensschritt erfolgt, in dem ein Kleberauftrag vorgenommen wird.According to the invention it is provided that the metallic surface for one Vehicle body is a specific sheet metal part and that the loading of this Sheet metal part with the medium takes place before a further process step in which a Glue application is made.
Das Medium, mit dem das Blechteil beaufschlagt wird, ist vorzugsweise ein Luftstrahl. Besonders geeignet ist für eine effektive Entfettung oder Entölung die Verwendung eines Heißluftstrahls. Alternativ dazu oder gleichzeitig kommt aber auch im Rahmen des erfindungsgemäßen Verfahrens die kontaktlose Reinigung des Blechteils mittels eines Laserstrahls in Betracht. Dieses Beaufschlagen des Blechteils mittels eines Laserstrahls kann auch vor oder nach der Reinigung mittels eines Luftstrahls erfolgen.The medium with which the sheet metal part is applied is preferably an air jet. The use of a is particularly suitable for effective degreasing or deoiling Hot air jet. Alternatively or at the same time, the inventive method the contactless cleaning of the sheet metal part by means of a Laser beam into consideration. This action on the sheet metal part by means of a laser beam can also be done before or after cleaning with an air jet.
Vorzugsweise erfolgt das Beaufschlagen des Blechteils mit dem Medium gemäß einer Weiterbildung der Erfindung unmittelbar vor dem Kleberauftrag. Man kann beispielsweise mittels des erfindungsgemäßen Verfahrens Bauelemente für eine Fahrzeugkarosserie aus den verschiedensten Materialien, zum Beispiel aus Kunststoff oder Metall nach dem Kleberauftrag an dem zuvor gereinigten Blechteil befestigen. Durch die vor dem Kleberauftrag vorgenommene Reinigung, zum Beispiel durch einen Heißluftstrahl haftet der aufgetragene Kleber fester und nachhaltiger auf dem Untergrund. Die Verwendung eines Luftstrahls hat gegenüber einem Heißluftstrahl den Vorteil, daß ersterer weniger energieintensiv ist. Da es immer ein grundsätzliches Anliegen ist Energie zu sparen, empfiehlt es sich, einen Heißluftstrahl nur dann zu verwenden, wenn die Art beziehungsweise der Umfang der zu entfernenden Öle oder Fette dies erfordern. Insbesondere bei Verunreinigungen mit niedrigeren Siedepunkten kann ein einfacher Luftstrahl genügen.The sheet metal part is preferably loaded with the medium according to a Development of the invention immediately before the adhesive application. One can, for example using the method according to the invention, components for a vehicle body made of different materials, for example plastic or metal according to the Attach the adhesive to the previously cleaned sheet metal part. By before Adhesive applied cleaning, for example by a hot air jet adheres the applied adhesive is stronger and more sustainable on the surface. The usage an air jet has the advantage over a hot air jet that the former is less is energy intensive. Since it is always a fundamental concern to save energy, it is advisable to use a hot air jet only if Art or the extent of the oils or fats to be removed. Especially with impurities with lower boiling points, an easier one Air jet is enough.
Die kontaktlose Reinigung mittels zum Beispiel eines Luftstrahls hat gegenüber den eingangs genannten Verfahren, die zusätzlich eine mechanische Reinigung vorsehen, den Vorteil, daß die für die Reinigung erforderliche Vorrichtung erheblich einfacher aufgebaut sein kann und auch die Handhabung in der Regel einfacher ist.The contactless cleaning by means of, for example, an air jet has compared to the the methods mentioned at the outset, which additionally provide mechanical cleaning, the advantage that the device required for cleaning is considerably easier can be constructed and handling is usually easier.
Eine Weiterbildung des erfindungsgemäßen Verfahrens sieht vor, daß das Beaufschlagen des Blechteils mit dem Medium und der Kleberauftrag sowie die anschließende Befestigung eines Bauelements an dem Blechteil mittels des Klebers erfolgt, bevor das daraus resultierende Bauteil in einem nachfolgenden Verfahrensschritt transportiert wird zu einem Verbauort, der von dem Ort an dem die Reinigung und Befestigung des Bauelements erfolgt verschieden ist. Die Anwendung des erfindungsgemäßen Verfahrens ist dabei insbesondere vorteilhaft beispielsweise in Fertigungsstätten, in denen komplexe Produkte aus einer Vielzahl von Einzelteilen in aufeinanderfolgenden Fertigungsschritten an verschiedenen Fertigungsplätzen montiert werden, wie dies zum Beispiel bei der Montage von Fahrzeugkarosserien in einem Automobilwerk der Fall ist.A further development of the method according to the invention provides that Applying the medium to the sheet metal part and the adhesive application as well as the then attaching a component to the sheet metal part using the adhesive takes place before the resulting component in a subsequent process step is transported to a place of installation that is from the place where the cleaning and Attachment of the component is different. The application of the The method according to the invention is particularly advantageous, for example, in Manufacturing facilities in which complex products made from a large number of individual parts successive manufacturing steps assembled at different manufacturing locations like, for example, the assembly of vehicle bodies in one Automobile plant is the case.
Die in den Unteransprüchen genannten Merkmale betreffen bevorzugte Weiterbildungen des erfindungsgemäßen Verfahrens.The features mentioned in the subclaims relate to preferred further developments of the method according to the invention.
