Abstract
Description
Die Erfindung betrifft ein Verfahren zur Entfernung von überschüssigen, nichtausgehärteten Klebern, insbesondere Epoxidharzklebern, von den Bördelkanten von Werkstücken, die durch Bördeln und Verkleben von Einzelteilen gebildet werden, wie Türen, Heckklappen und Motorhauben von Automobilen.The invention relates to a method for removing excess, uncured adhesives, in particular epoxy resin adhesives, from the flanged edges of workpieces which are formed by flanging and gluing individual parts, such as doors, tailgates and bonnets of automobiles.
In der Automobilindustrie geht man mehr und mehr dazu über, die Innen- und Außenteile von Türen, Heckklappen und Motorhauben nicht mehr durch Punktschweißen zu verbinden, sondern zu verkleben. Hierzu werden Epoxidharzkleber verwendet. Auch die Herstellung derartiger Klebeverbindungen wird in zeitgesteuerten Fertigungsstraßen eingegliedert. Beispielsweise wird mit sogenannten "Arbeitsrobotern" in mehreren Arbeitsgängen der Epoxidharzkleber in die offene Bördelfalz dosiert und eingespritzt. Bei geraden oder leicht gekrümmten Bördelkanten läßt sich der Kleber so exakt dosieren, daß bei der letzten Bördelung kaum Kleber aus der Falz austritt. Dies trifft jedoch nicht zu für die Ecken der Werkstücke. Da eine hohe Qualität der Verbindung gefordert wird, muß hier der Kleber überdosiert werden. Beim Bördelvorgang tritt daher ein Teil des Klebers aus der Naht hervor. Dieser überschüssige Kleber muß gründlich entfernt werden, da er andernfalls den nachfolgenden Arbeitsprozeß beeinträchtigen würde.In the automotive industry, there is a growing tendency to no longer connect the inner and outer parts of doors, tailgates and bonnets by spot welding, but to glue them together. Epoxy resin adhesives are used for this. The production of such adhesive connections is also integrated in time-controlled production lines. For example, with so-called "work robots", the epoxy resin adhesive is placed in the open in several work steps Flare fold dosed and injected. With straight or slightly curved flanged edges, the adhesive can be dosed so precisely that hardly any glue escapes from the fold during the last flanging. However, this does not apply to the corners of the workpieces. Since a high quality of the connection is required, the adhesive must be overdosed here. During the flanging process, part of the adhesive emerges from the seam. This excess glue must be removed thoroughly, otherwise it would impair the subsequent work process.
Derzeit wird der überschüssige Kleber von Hand entfernt. Ein derartiger Arbeitsgang ist lohnintensiv und dem Bestreben entgegengerichtet, den Fertigungsvorgang möglichst weitgehend zu automatisieren.The excess adhesive is currently being removed by hand. Such an operation is cost-intensive and opposes the effort to automate the manufacturing process as much as possible.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Entfernung von überschüssigen Klebemzu schaf- fen, welches in eine zeitgesteuerte Fertigungsstraße eingegliedert werden kann.The invention is therefore based on the object of providing a method for removing excess adhesive which can be incorporated into a time-controlled production line.
Es wurde nun ein Verfahren zur Entfernung von überschüssigen, nichtausgehärteten Klebern, insbesondere Epoxidharzklebern, von den Bördelkanten von Werkstücken, die durch Bördeln und Verkleben von Einzelteilen gebildet werden, wie Türen, Heckklappen und Motorhauben von Automobilen, gefunden, bei dem gemäß der Erfindung der Kleber durch ein tief- kaltes verflüssigtes Gas vorübergehend versprödet und durch mechanische Einwirkung vom Werkstück abgesprengt wird.A method has now been found for removing excess, uncured adhesives, in particular epoxy resin adhesives, from the flanged edges of workpieces which are formed by flanging and gluing individual parts, such as doors, tailgates and bonnets of automobiles, in which, according to the invention, the adhesive temporarily embrittled by a cryogenic liquefied gas and blasted off the workpiece by mechanical action.
Es ist an sich bekannt, daß sich Flüssigkeiten und Pasten, also auch Klebstoffe, bei genügender Abkühlung verspröden lassen. Es ist auch bekannt, daß sich Verbundmaterialien, wie beispielsweise Elektrokabel oder Altreifen von Antomobilen durch Kältezufuhr und nachfolgende mechanische Einwirkung verspröden und voneinander trennen lassen. Es war jedoch nicht zu erwarten, daß sich auch ein Klebstoff auf diese Weise vom Grundmaterial wieder würde entfernen lassen. Insbesondere war nicht zu erwarten, daß sich die Entfernung des Klebestoffes ohne Beeinträchtigung der Rostschutzschicht würde bewerkstelligen lassen. Derartige Rostschutzschichten befinden sich auf den Karosserieblechen von Türen, Heckklappen und Motorhauben im Automobilbau. Ferner war nicht zu erwarten, daß sich die mechanische Einwirkung durchführen lassen würde, ohne die Oberfläche des dünnen und daher empfindlichen Karosserieblechs zu beschädigen.It is known per se that liquids and pastes, including adhesives, can become brittle if they are cooled sufficiently. It is also known that composite materials, such as electrical cables or used tires from antomobiles, are caused by the cold supply and subsequent mechanical ones Brittle action and let it separate. However, it was not to be expected that an adhesive could also be removed from the base material in this way. In particular, it was not to be expected that the removal of the adhesive would be possible without impairing the rust protection layer. Such rust protection layers are located on the body panels of doors, tailgates and bonnets in automotive engineering. Furthermore, it was not to be expected that the mechanical action could be carried out without damaging the surface of the thin and therefore sensitive body panel.
Da darüber hinaus angestrebt wurde, das erfindungsgemäße Verfahren zu automatisieren und in eine zeigesteuerte Fertigungsstraße einzugliedern, kam als weiteres Erschwernis hinzu, daß sich das gesamte Verfahren in der heute üblichen kurzen Taktzeit von etwa 30 Sekunden durchführen lassen mußte. Für die Verfahrensschritte Verspröden und mechanisches Einwirken standen daher nur jeweils etwa 12 Sekunden Zeit zur Verfügung. Unter den vorgegebenen Bedingungen erwies sich flüssiger Stickstoff als optimales Kühlmedium da dieses tiefsiedende verflüssigte Gas eine sehr intensive Kühlung ermöglicht und in genügender Menge preiswert zur Verfügung steht. Eine besonders intensive Kühlwirkung wird mit einer Vorrichtung erreicht, die im wesentlichen aus einem geschlossenen, geschlitzten Rohr besteht, dessen Schlitz die Bördelkante aufnimmt und in welches flüssiger Stickstoff eingeleitet wird. In dem Rohr wird ein Bad aus flüssigem Stickstoff aufrecht erhalten. Wenn von oben der flüssige Stickstoff zugeführt wird, wird auf diese Weise die Bördelkante von beiden Seiten mit flüssigem Stickstoff beaufschlagt. Der verdampfte tiefkalte Stickstoff entweicht mit großer Geschwindigkeit durch den Schlitz was zu einer zusätzlichen intensiven Kühlung der Bördelkante führt. Derartige Rohre können zudem durch Pneumatikzylinder in die Arbeitsposition geführt werden, so daß der Verfahrenschritt automatisiert werden kann.In addition, since the aim was to automate the method according to the invention and to integrate it into a production line controlled by a pointer, a further difficulty was that the entire method had to be able to be carried out in the short cycle time of about 30 seconds which is customary today. For the process steps embrittlement and mechanical action, there was therefore only about 12 seconds each available. Under the given conditions, liquid nitrogen proved to be the optimal cooling medium, since this low-boiling liquefied gas enables very intensive cooling and is cheaply available in sufficient quantities. A particularly intensive cooling effect is achieved with a device which essentially consists of a closed, slotted tube, the slot of which receives the flanged edge and into which liquid nitrogen is introduced. A bath of liquid nitrogen is maintained in the tube. If the liquid nitrogen is fed in from above, the flanged edge is acted upon from both sides with liquid nitrogen. The evaporated cryogenic nitrogen escapes through the slot at high speed, which results in additional intensive cooling of the Flanged edge leads. Such tubes can also be guided into the working position by pneumatic cylinders, so that the process step can be automated.
Die mechanische Einwirkung zum Absprengen des versprödeten Klebers kann an sich vielfältiger Art sein. So bringen bereits einige Schläge oder eine geringe Fallenergie den versprödeten Kleber zum Abplatzen. Dies führt aber zu Beschädigungen des Bleches. Auch das Vorbeiziehen eines Schraubenziehers reicht aus, um den überflüssigen Kleber zu entfernen. Es ist jedoch in jedem Fall eine Sichtkontrolle erforderlich, um sicherzustellen, daß hierdurch weder das Blech noch seine Rostschutzschicht beschädigt worden ist. Für eine Automatisierung ist diese Art der mechanischen Einwirkung daher ungeeignet. Dasselbe gilt auch für die Verwendung von Hand- Drahtbürsten, der mit denen überflüssige Kleber ebenfalls zufriedenstellend entfernt werden kann. Werden dagegen anstelle von Hand-Drahtbürsten maschinell angetriebene Topfbürsten verwendet, so wird zuviel Energie zugeführt, der Kleber verschmiert sofort.The mechanical action for blasting off the embrittled adhesive can in itself be diverse. Even a few blows or a low fall energy will cause the brittle adhesive to flake off. However, this leads to damage to the sheet. Pulling a screwdriver past is also sufficient to remove the superfluous glue. However, a visual inspection is always required to ensure that neither the sheet nor its rust protection layer has been damaged. This type of mechanical action is therefore unsuitable for automation. The same applies to the use of hand wire brushes, which can also be used to remove excess glue satisfactorily. On the other hand, if machine-operated pot brushes are used instead of hand wire brushes, too much energy is applied and the adhesive smears immediately.
Als sehr gut geeignet für die mechanische Einwirkung haben sich dagegen druckluftgetriebene Nadelpistolen erwiesen. Die Nadelpistolen können ohne Schwierigkeit mittet eines Industrieroboters in einer zeitgesteuerten Fertigungsstraße verwendet werden. An den Nadelpistolen können zudem Düsen befestigt werden, aus denen kaltes verdampftes Gas ausgeblasen wird. Hierdurch werden die abgesprengten versprödeten Kleberteile vom Blech entfernt, bevor sie wieder erweichen und erneut am Blech festhaften. Die weggeblasenen Kleberteile können aufgefangen und nach Erweichung erneut als Kleber verwendet werden. Ein Ausführungsbeispiel der'Erfindung soll anhand der beigefügten Zeichnungen erläutert werden.In contrast, compressed air-driven needle guns have proven to be very well suited for mechanical action. The needle guns can be used in a time-controlled production line without difficulty using an industrial robot. In addition, nozzles can be attached to the needle guns, from which cold evaporated gas is blown out. As a result, the brittle, embrittled adhesive parts are removed from the sheet before they soften again and adhere again to the sheet. The blown away parts of the glue can be collected and reused as glue after they have softened. An embodiment of the ' invention will be explained with reference to the accompanying drawings.

Die in Fig.1 gezeigte Ecke einer Bördelkante besteht aus dem Blechunterteil 1, dem Blechoberteil 2, der Bördelnaht 4 und dem überschüssigen Kleber 3.The corner of a flanged edge shown in FIG. 1 consists of the sheet metal lower part 1, the sheet metal upper part 2, the flanged seam 4 and the
In Fig.2 ist die Ecke von einem geschlitzten Rohr 5 zwecks Beaufschlagung mit flüssigem Stickstoff aufgenommen. Die Stickstoffzufuhr erfolgt durch Anschlußstutzen 6. Der flüssige Stickstoff sammelt sich am Boden des geschlitzten Rohres 5 als Stickstoffbad 7. Die Bördelnaht 4 wird daher beidseitig von flüssigem Stickstoff beaufschlagt. Der verdampfte Stickstoff 8 entweicht durch den Schlitz 9 und trägt auf diese Weise zur Kühlung der Bördelkante bei.. In Fig.2 ist das geschlitzte Rohr 5 mit der Bördelkante im Vordergrund im Schnitt dargestellt.In Figure 2, the corner is taken up by a slotted

In einer zeitgesteuerten Fertigungsstraße spielt sich das erfindungsgemäße Verfahren so ab, daß zunächst durch Pneumatikzylinder an jede der vier Ecken der Bördelkante ein geschlitztes Rohr 5 geführt wird. Sobald die Ecken von den geschlitzten Rohren 5 aufgenommen sind, erfolgt während 8 bis 15 Sekunden die Zufuhr von flüssigem Stickstoff. Danach werden die geschlitzten Rohre 5 zurückgenommen und druckluftbetriebene Nadelpistolen 11 durch Arbeitsroboter über die Bördelnaht 4 geführt. Der überschüssige versprödete Kleber wird abgesprengt und weggeblasen. Dieser Arbeitsvorgang dauert 8 bis 12 Sekunden, so daß sich das gesamte erfindungsgemäße Verfahren in einem Arbeitstakt von 30 Sekunden durchführen läßt.In a time-controlled production line, the method according to the invention takes place in such a way that a
Ähnliche Schwierigkeiten wie beim Bördeln und Verkleben von beispielsweise Türen und Motorhauben von Automobilen treten auf, wenn rechtwinklig abgebogene Bleche mit kurzem Schenkel stumpf gegeneinander geklebt werden sollen. Auch hierbei läßt sich das erfindungsgemäße Verfahren sinngemäß anwenden.Difficulties similar to flanging and gluing, for example, doors and bonnets of automobiles occur when right-angled sheets with short legs are to be butted against each other. Here, too, the method according to the invention can be applied analogously.
