Description

Die Erfindung betrifft ein Verfahren zum Befestigen einer lichtdurchlässigen Abschlussscheibe an einem Blendrahmen einer Beleuchtungseinrichtung, insbesondere eines Fahrzeugscheinwerfers, bei der der Blendrahmen aus einem teilkristallinen Kunststoffmaterial hergestellt ist.The The invention relates to a method of attaching a translucent Cover lens on a frame of a lighting device, in particular a vehicle headlamp, wherein the frame is made of a semi-crystalline plastic material.

Ferner betrifft die Erfindung ein Halbzeug für eine Beleuchtungseinrichtung eines Fahrzeugs enthaltend eine lichtdurchlässige Abschlussscheibe aus einem Kunststoffmaterial und einen Blendrahmen aus einem teilkristallinen Kunststoffmaterial, die in einem randseitigen Befestigungsbereich miteinander verbunden sind.Further The invention relates to a semi-finished product for a lighting device a vehicle containing a translucent lens made of a plastic material and a frame made of a semi-crystalline Plastic material in a marginal mounting area connected to each other.

Aus der DE 43 10 048 C2 ist es bereits bekannt, zur Befestigung einer lichtdurchlässigen Abschlussscheibe an einem gehäuseseitigen Tragelement ein stiftförmiges Arretierungsmittel einzusetzen, wobei das stiftförmige Arretierungsmittel in einer überlappenden Solllage eines Randes der Abschlussscheibe und des Tragelementes quer zu denselben eingetrieben wird. Die Lage der Abschlussscheibe relativ zu dem Tragelement ist somit justiert, so dass ein unerwünschtes Wandern des Randes der Abschlussscheibe in einer mit einem Klebebett (aushärtbaren Dichtungsmittel) versehenen Aufnahme des Tragelementes weitgehend verringert wird. Durch das erwärmte Arretierungsmittel erfolgt beim Eintreiben eine partielle Plastifizierung der Eintreibstelle, so dass im Innern der Abschlussscheibe keine Verspannungskräfte auftreten, die zu einer unerwünschten Rissbildung der Abschlussscheibe führen könnten. Es hat sich jedoch herausgestellt, dass diese Art der Arretierung nicht geeignet ist für die Verbindung der lichtdurchlässigen Abschlussscheibe mit einem Blendrahmen aus einem teilkristallinen Kunststoffmaterial. Bei dem Blendrahmen kommt es in der Eintreibstelle zu Brüchen, die offensichtlich aufgrund des spröden Materials des Blendrahmens zurückzuführen sind. Die Befestigung der Abschlussscheibe an dem Blendrahmen wurde daher bisher auf andere Art und Weise durchgeführt.From the DE 43 10 048 C2 It is already known to use a pin-shaped locking means for fixing a translucent cover plate on a housing-side support member, wherein the pin-shaped locking means is driven transversely to the same in an overlapping desired position of an edge of the cover plate and the support element. The position of the cover plate relative to the support element is thus adjusted, so that an undesired migration of the edge of the lens in a provided with an adhesive bed (curable sealant) receiving the support element is largely reduced. Due to the heated locking means, a partial plastification of the drive-in point takes place during driving, so that no bracing forces occur in the interior of the cover disk which could lead to undesired cracking of the lens. However, it has been found that this type of locking is not suitable for the connection of the translucent lens with a frame of a semi-crystalline plastic material. In the frame there are breaks in the drive point, which are obviously due to the brittle material of the frame. The attachment of the lens to the frame has therefore been carried out in other ways.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zum Befestigen einer lichtdurchlässigen Abschlussscheibe an einem Blendrahmen einer Beleuchtungseinrichtung bzw. ein Halbzeug bestehend aus Abschlussscheibe und Blendrahmen derart anzugeben, dass eine einfache und kostengünstige Befestigung ohne Bruchgefahr des Blendrahmens gewährleistet ist.task The present invention is a method for fastening a translucent lens on a frame a lighting device or a semi-finished product consisting of lens and specify the frame so that a simple and inexpensive attachment without risk of breakage of the frame is guaranteed.

Der besondere Vorteil des erfindungsgemäßen Verfahrens besteht darin, dass durch das Erwärmen eines mit einer Abschlussscheibe zu verbindenden Blendrahmens die Duktilität des teilkristallinen Kunststoffmaterials des Blendrahmens soweit erhöht wird, dass es nicht zur Materialbrüchen infolge des Eintreibens des Arretierungsmittels kommt. Vorteilhaft kann somit eine an sich bewährte einfache und kostengünstige Befestigungsart auch für aus einem teilkristallinen Kunststoffmaterial bestehende Bauteile verwendet werden. Beispielsweise kann das so gebildete Halbzeug bestehend aus lichtdurchlässiger Abschlussscheibe und einem Blendrahmen als Vormontagegruppe bereitgestellt und dann zur Herstellung eines Scheinwerfers randseitig in eine Aufnahmenut eines gehäuseseitigen Tragelementes eingesetzt und mit demselben dichtend verklebt werden.Of the particular advantage of the method according to the invention is that by heating one with a Cover glass to be connected frame the ductility of the semi-crystalline plastic material of the frame so far it is increased that it does not cause the material to break comes due to the driving of the locking means. Advantageous can thus be a proven simple and inexpensive Mounting also for a semi-crystalline plastic material existing components are used. For example, it can do that formed semi-finished product consisting of translucent lens and a frame provided as a pre-assembly group and then for producing a headlamp edge in a receiving groove a housing-side support element used and with be glued to the same sealing.

Erweichungstemperatur des Blendrahmenmaterials, so dass der Befestigungsbereich des Blendrahmens beim Eintreiben des Arretierungsmittels ein entropieelastisches (duktiles) Materialverhalten aufweist. Dadurch, dass das Arretierungsmittel zumindest unter partieller Erwärmung des Blendrahmens in den Befestigungsbereich auf die Arretie rungstemperatur eingetrieben wird, können unerwünschte Sprödbrüche des Blendrahmens nach Abschluss des Arretiervorgangs vermieden werden.To a preferred embodiment of the invention is at least the mounting portion of the frame to such a locking temperature preheated, which is equal to or higher than one given glass transition temperature or softening temperature of the frame material, so that the mounting area of the frame when driving the locking means an entropy-elastic (ductile) material behavior. In that the locking means at least under partial heating of the frame in the Mounting area driven to the Arretie tion temperature can be unwanted brittle fractures of the frame after completion of the locking operation can be avoided.

Nach einer Weiterbildung der Erfindung wird zumindest ein im Befestigungsbereich liegender Rand des Blendrahmens durch Laserstrahlung oder durch Infrarotstrahlung oder durch Heißluft vorerwärmt, so dass nachfolgend das Arretierungsmittel unter einer ausreichend hohen Arretierungstemperatur in den Blendrahmen eingetrieben werden kann. Vorteilhaft kann die Vorerwärmung durch Laserstrahlung oder durch Infrarotstrahlung oder durch Heißluft auf einfache Weise in einem vorherigen Prozessschritt erfolgen.To a development of the invention is at least one in the attachment area lying edge of the frame by laser radiation or by Infrared radiation or preheated by hot air, so that below the locking means under a sufficient high locking temperature are driven into the frame can.

Vorteilhaft wird hierbei die nach außen liegende Oberfläche der Abschlussscheibe nicht durchstoßen, so dass ein hohes Maß an Dichtigkeit gegeben ist. Nach einer Weiterbildung der Erfindung werden die miteinander arretierte Abschlussscheibe und der Blendrahmen randseitig in eine Aufnahmenut eines gehäuseseitigen Tragelementes eingesetzt, das mit einem Dichtungsmittel (Klebebett) versehen ist, so dass nachfolgend eine sichere, feste und dichte Verbindung zwischen der Abschlussscheibe und dem Blendrahmen einerseits und dem Tragelement andererseits gewährleistet ist.According to a development of the invention, the locking means is driven into an interior of the lighting device facing the inside of the frame, wherein the locking means is driven only partially into the edge of the lens. The advantage here is the outward surface of the conclusion not pierced, so that a high degree of tightness is given. According to a development of the invention, the locked-together lens and the frame are inserted into the edge of a receiving groove of a housing-side support member, which is provided with a sealant (adhesive bed), so that subsequently a secure, firm and tight connection between the lens and the frame on the one hand and the support element is guaranteed on the other hand.

Nach einer Weiterbildung der Erfindung kann das Arretierungsmittel in dem Bereich einer Randlasche der Abschlussscheibe bzw. Randlappens des Blendrahmens, die später in eine Aufnahmenut des Tragelementes eingesetzt worden ist, einerseits oder in einem zu demselben benachbarten Randabschnitt, der nicht in einer Aufnahmenut des Tragelementes eingefasst ist, eingetrieben werden. Vorteilhaft kann somit die Befestigung der drei Bauteile Abschlussscheibe, Blendrahmen und Tragelement in zwei Befestigungsschritten erfolgen. Im ersten Schritt wird die Abschlussscheibe mit dem Blendrahmen durch Eintreiben des Arretierungsmittels in dem Befestigungsbereich derselben verbunden. Im zweiten Schritt wird die Abschlussscheibe zusammen mit dem Blendrahmen in die Aufnahmenut des Tragelementes eingesetzt, wobei nach Aushärten des Klebebettes eine dichte und feste Verbindung zwischen dem aus der Abschlussscheibe und dem Blendrahmen gebildeten Halbzeug einerseits und dem Tragelement andererseits geschaffen wird.To a development of the invention, the locking means in the area of a marginal flap of the lens or edge flap of the frame, which later in a receiving groove of the support element has been used, on the one hand or in an adjacent to the same edge portion, which is not enclosed in a receiving groove of the support element, be driven.
