Die Erfindung . ezieht sich auf eine Vorrichtung zurr. Verbinden eines schitalen, eine Frontscheibe umfassenden Kuns-srcffrahrr.ens mit einer hinter der Frontscheibe liegenden Kunststoffabdeckblende von größerer Masse unter Anwendung von Ultraschall energie.The invention . Retracts to a device. associate a schitalen, a front window encompassing plastic frame with a plastic cover panel located behind the windshield of greater mass using ultrasonic energy.

Die Ultraschallschv.'eißung wird bei Kunststoff teilen verschiedener Art und Große in schnell steigendem Umfang eingesetzt. Sie ermöglicht eine erhebliche Arbeitszeiteinsparung gegenüber der. Verkleben und anderen bekannten Verbindungstechniker.. Die zuUltrasonic welding is different for plastic parts Type and size used to a rapidly increasing extent. It enables a considerable saving of working time compared to the. Gluing and other well-known connection technicians .. The too

verbindenden Teile müssen durch besondere Formgebung der. Ultraschallschweißverfahren angepaßt werden. Die Fachliteratur (VDI-Taschenbuch T8, Kunststoffe II, 1965, Seite liy) fordert, daß der Abstand zwischen Sonotrode und Schweißnaht, möglichst: klein sein soll. Es ist daher allgemein üblich, das größere Werkstück in einer Aussparung des Amboß zu fixierer, und das Energie abstrahlende Horn auf das kleinere Werkstück aufzupressen. Bei dieser Methode wird die kleinere Mriibe so weit beschleunigt, daß an den Reibungsstellen mit dem größerer. Werkstück ein Schweißvorgang einsetzt, der zu einer innigen Verbindung der beiden Kunststoffteile führt.connecting parts have to be shaped by the special shape of the. Ultrasonic welding process can be adapted. The specialist literature (VDI-Taschenbuch T8, Kunststoffe II, 1965, page liy) calls for that the distance between the sonotrode and the weld seam, if possible: should be small. It is therefore common practice to fix the larger workpiece in a recess in the anvil, and that Pressing the energy-emitting horn onto the smaller workpiece. With this method, the smaller membrane becomes so wide accelerates that at the points of friction with the larger. Workpiece starts a welding process, which leads to an intimate Connection of the two plastic parts leads.

Der Erfindung liegt die Aufgabe zugrunde, die für Me.:gi.-rätegehäuse oder dgl. bestimmten Kunststoffror.trar.raer. unter Einfügung einer Frontscheibe aus Glas mit einer Kunststoffabdeckblende zu verschweißen. Der die Glasscheibe umfassende Fror.tr ahme η weist dabei nur einen Bruchteil der Masse- der Kur.st.stof fabdeckblende auf. Bei einer SchweißarOrdnung, bei der das Horn entsprechend der Lehre der Fachliteratur auf den dünnen Frontrahmen aufliegt, gelang es nicht, einwandfreie Schweißverbindungen herzustellen. Eine zur Verbesserung des Scr.v.-eißvorganges erforderliche Erhöhung des Anpreßdruckes führte dazu, daß ein großer Teil der Glasscheiben unter der Belastung zerbrach.The invention is based on the object that for Me.:gi.-ratsegehäuse or the like. Certain Kunststoffror.trar.raer. with the insertion of a front pane made of glass with a plastic cover panel to weld. The frost frame η encompassing the glass pane has only a fraction of the mass of the fabric cover panel on. With a welding order where the horn according to the teaching of the specialist literature on the thin front frame rests on, it was not possible to produce perfect welded joints. One necessary to improve the scr.v.-icing process An increase in the contact pressure resulted in a large part of the glass panes breaking under the load.

Gemäß der Erfindung werden diese Schwierigkeiten dadurch beseitigt, daß der Kunststoffrahmen in einer Aussparung des Amboß ruht und daß das die Ultraschallenergie übertragende Korn auf der Abdeckblende aufliegt.According to the invention, these difficulties are eliminated by that the plastic frame in a recess in the anvil rests and that the grain transmitting the ultrasonic energy rests on the cover panel.

Null zurückging.Zero decreased.

Eine besonders vorteilhafte Weiterbildung der Erfindung besteht darin, daß der Amboß mittels eines KugeiKalottenlagers nach allen Richtungen begrenzt schwenkbar gelagert; ist. Durch diese Maßnahme erreicht man über den gesamten Unfang des Werkstückes unter Eliminierung der Werkstückstoleranzen einen gleichmäßigen Anpreßdruck und damit eine gute Schweißnaht.A particularly advantageous further development of the invention consists in that the anvil by means of a spherical ball bearing after all Directions can be pivoted to a limited extent; is. By this measure a uniform contact pressure is achieved over the entire circumference of the workpiece while eliminating workpiece tolerances and thus a good weld seam.

tine weitere zweckmäßige Ausgestaltung der Vorrichtung besteht darin, daß die den Kunststoffrahmen aufnehmende Aussparung des Amboß mit einem weichen Leder ausgekleidet ist. Hierdurch vermeidet man jede Beschädigung der Ansichtfläche des Kunststoffrahmens. There is another useful embodiment of the device in that the recess of the anvil receiving the plastic frame is lined with a soft leather. This avoids any damage to the face of the plastic frame.

Die Erfindung wird an Hand eines Ausführungsbeirpieles gemäß Figur 1 bis 6 der Zeichnung erläutert:The invention is based on an exemplary embodiment according to Figure 1 to 6 of the drawing explains:

In Figur 1 ist mit 1 das Ultraschall abstrahlende Horn oder die Sonotrode bezeichnet. Dieses Horn ist mit dein nicht: dargestellten Ultraschallerzeuger verbunden und kann hydraulisch oder pneumatisch in Richtung des Pfeiles Io verstelle werden. Der Arbeitstisch der Schweißmaschine ist mit 2 bezeichnet. Au: diesem Arbeitstisch ruht ein Amboß 3, der eine Auss^ar-r.u zu: Aufnahme des Werkstückes 4 aufweist. Zwischen Arbeitstisch 2 und Amboß 3 ist ein Kugelkalottenlager 5 vorgeseher., das- nach allen Richtungen begrenzt schwenkbar ist. Die das Werkstück aufnehmende Aussparung des Amboß "\ ist allseitig mit weichem Leder 6 ausgekleidet. Gut bewähr- h-t sich hierfür normales Fensterleder.In FIG. 1, 1 denotes the horn which emits ultrasound or the sonotrode. This horn is connected to the ultrasonic generator (not shown) and can be adjusted hydraulically or pneumatically in the direction of the arrow Io. The work table of the welding machine is denoted by 2. On this work table rests an anvil 3, which has an outer surface to receive the workpiece 4. A spherical cap bearing 5 is provided between work table 2 and anvil 3, which can be pivoted to a limited extent in all directions. The workpiece receiving recess of the anvil "\ sides is lined with soft leather. 6 Well proven ht this purpose are normal window leather.

Das Werkstück 4 besteht aus dem Kunststoffrahmen 4a und der Kunststoffabdeckblende 4b. Die ebene Unterseite des Horr.es 1 ruht mit einstellbarem Anpreßdruck auf der Kunststoffabdeckblende 4b. Der wesentlich leichtere und flachere Kunststoffrahmen 4a liegt in der Aussparung des Amboß 3. Bei dieser Anordnung der Teile hat also die mit strichpunktierten Linien angedeutete Schweißnaht 7 einen wesentlich größeren AV.stand von dem Horn 1 als bei umgekehrter Lage der Teile. Entgegen der Lehre der Fachleute liefert die dargestellte Vorrichtung bei den zu verbindenden Teilen die einzig brauchbaren Schweissungen. The workpiece 4 consists of the plastic frame 4a and the Plastic cover 4b. The flat underside of the Horr.es 1 rests with adjustable contact pressure on the plastic cover panel 4b. The much lighter and flatter plastic frame 4a lies in the recess of the anvil 3. With this arrangement of the parts, it has the dot-dash lines indicated weld seam 7 a much larger AV. stand of the horn 1 than when the parts are reversed. Contrary to the teaching of those skilled in the art, the device shown provides the only usable welds on the parts to be connected.

Aus Figur 2 ist zu ersehen, daß zwischen dem Kunststoffrahmen 4a und der Kunststoffabdeckblende 4b eine Glasscheibe ? angc-Ο-ν.Γ.οί" ist.. Die Glasscheibe 8 wird seitlich von eir.o" urr.lf.uftr.-den Steg der Kunststoffabdeckblendo 4b gehalten. Der 7rcntrahmen 4a liegt mit einer umlaufei.-en Lippe au: der G^erseite der Glasscheibe auf und dichtet sie gegen das Eindringen von Fremdkörpern ab.From Figure 2 it can be seen that between the plastic frame 4a and the plastic cover 4b a pane of glass? angc-Ο-ν.Γ.οί " is .. The glass pane 8 is laterally by eir.o "urr.lf.uftr.-den Web of the plastic cover blendo 4b held. The 7rcntrahmen 4a lies with a circumferential lip on the front side the glass pane and seals it against the ingress of foreign bodies.

Figur 3 zeigt einen vergrößerten Ausschnitt aus Figur 2, Der umlaufende Steg der Kunststoffabdeckbler.de 4b ist an einiger. Stellen mit angespritzten Noppen 4c versehen, die der. Ausgleich der Außentoleranz der Glasscheibe 8 dienen. Der u~laufer.deFigure 3 shows an enlarged section from Figure 2, Der circumferential web of the Kunststoffabdeckbler.de 4b is on some.

Die Energieübertragung vom Horn 1 auf das Werkstück 4 kann erheblich verbessert werden, wenn man das Horn mit einer dünnen Schicht aus Silikonpaste versieht. Diese Silikonpaste vermeidet störende Luftschichten zwischen Metall und Kunststoff und sorgt ; für eine gleichmäßige Schalleinleitung in das Werkstück. Es ist zweckmäßig, diese Schicht nach jedem Schweißvorgang zu erneuern.The energy transfer from the horn 1 to the workpiece 4 can be considerably improved if the horn is provided with a thin layer of silicone paste. This silicone paste avoids disturbing layers of air between metal and plastic and ensures ; for an even introduction of sound into the workpiece. It is advisable to renew this layer after each welding process.

Da Uitraschallerzeuger auch Frequenzen im hörbaren Bereich ab- : strahlen, wird das gesamte schwingende System mit einer Haube \ aus dämpfendem Material umgeben. Hierdurch gelingt es, die während der Schweißzeit auftretenden schrillen Geräusche auf einen nicht mehr störenden Pegel zu reduzieren.Since Uitraschallerzeuger also frequencies in the audible range off: rays, the whole oscillating system is surrounded by a hood \ of damping material. This makes it possible to reduce the shrill noises occurring during the welding time to a level that is no longer disruptive.

Die Erfindung ist nicht auf das Verschweißen eines Frontrahmens mit einer Abdeckblende beschränkt. Sie kann vielmehr überall dort mit Erfolg angewandt werden, wo größere Kunststoffteile unrcrschiedlir-.ier Masse oder Dicke miteinander zu verschweißen sind.The invention is not limited to welding a front frame to a cover panel. Rather, it can be used anywhere can be used with success where larger plastic parts to be welded to one another independently of the mass or thickness are.
