Verfahren zum Verschweißen einer Kunststofflinse mit einer Kunststoffassung Die Erfindung betrifft ein Verfahren zum Versohweißen und Justieren einer Kunststofflinse mit einer Kunststoffassung mittels Ultraschall und nach diesem Verfahren verschweißte Linsen.Method for welding a plastic lens to a plastic frame The invention relates to a method for welding and adjusting a plastic lens welded with a plastic frame by means of ultrasound and according to this process Lenses.
Gewöhnlich werden Linsen aus organischem Glas mit Kunststofffassungen entweder verklebt oder durch Wärmebehandlung durch Umbördeln verbunden oder mit Wärmestempeln zusammengepreßt.Lenses are usually made from organic glass with plastic frames either glued or connected by heat treatment by flanging or with Heat stamps pressed together.
Dabei gibt es keine Möglichkeit, die Linsen in einer beispielsweise gegenUber einer Auflagefläche, die mit einer kameraseitigen Auflagefläche verbunden wird, justierten Lage an der Fassung zu befestigen, so daß die Justierung von Kunststoffobjektiven in Kameras oft erhebliohe Schwierigkeiten bereitet.There is no way of using the lenses in one example opposite a support surface that is connected to a camera-side support surface is to attach adjusted position on the mount, so that the adjustment of plastic lenses often causes considerable difficulties in cameras.
Der Erfindung liegt die Aufgabe zugrunde, Kunststofflinsen beim Verschweißen mit der Kunststoffassung gegenüber einer Auflagefläche der Fassung, die an einer kameraseitigen Auflage zur Anlage kommt, derart zu justieren, daß beim Einbau der Fassung in eine Kamera die Linse den Sollabstand von der Filmbahn in der Kamera hat. Zur Lösung dieser Aufgabe eignet sich besonders das an sich bekannte Ultraschallschweißverfahren, bei dem die miteinander zu verbindenden Kunststoffteile infolge der Erwärmung durch die Ultraschalleinwirkung miteinander verfließen. Gemäß der Erfindung wird zwecks gleichzeitigen Verschweißens und Justierens einer Kunststofflinse in einer Kunststoffassung mittels Ultraschall vorgeschlagen, daß Linse und Fassung nur im Bereich von zum Verschweißen vorgesehenen Bünden-beschallt werden und daß der axiale Auflagesollwert der Linse gegenüber einer Auflagefläche an der Fassung, die an einer Auflagefläßhe einer Kamera zur Anlage kommt, vor Verschweißen mittels eines optischen Prüfgerätes duroh die Sonotrode beobachtet und eingestellt und die Sonotrode bei Erreichen dieses Auflagesollwertes abgeschaltet wird. Da die Fassung beim Verschweißen nicht an die Auflagefläche der zugehörigen Kamera angelegt werden -kann, ist es zweckmäßig, daß die Fassung auf eine mit der Sonotrode zu einem Gerät vereinigte Auflage aufgesetzt wird und das optische Prüfgerät gegenüber der Auflage in einer zur Bestimmung des Auflagesollwertes det~Linse gegenüber der Au£-lage an der Fasiung geeigneten Lage angeordnet ist. na die Justierung bei der Ultraschallschweißung durch Verfließen der Bünde bis zur Erreichung des Auflagesollwertes erzielt wird, sollen die Bünde vor der Ultraschallbehandlung einen größeren Abstand als den Auflagesollwert von der Auflage haben.The invention is based on the object of welding plastic lenses with the plastic socket opposite a support surface of the socket that is attached to a camera-side support comes to the plant to adjust such that when installing the Mount the lens in a camera at the target distance from the film web in the camera Has. The known ultrasonic welding process is particularly suitable for solving this task, in which the plastic parts to be joined together as a result of the heating through the effects of ultrasound flow together. According to the invention is for the purpose simultaneous welding and adjustment of a plastic lens in a plastic frame suggested by means of ultrasound that lens and frame only in the area of the Welding provided collars are sonicated and that the axial support target value of the lens opposite a support surface on the frame, which is on a support surface a camera comes to rest before welding by means of an optical test device duroh the sonotrode observed and adjusted and the sonotrode when it is reached Support setpoint is switched off. Since the socket does not adhere to the Support surface of the associated camera can be created, it is advisable that the socket placed on a support combined with the sonotrode to form a device and the optical tester compared to the edition in a to determine the Setpoint value of the lens against the support on the bevel is a suitable position is arranged. well that Adjustment for ultrasonic welding is achieved by flowing the frets until the target value is reached, Before the ultrasound treatment, the frets should have a greater distance than the nominal contact value have from the edition.
Eine nach diesem Verfahren in einer Kunststoffassung angeordnete Kunststofflinse ist dadurch gekennzeichnet, daß die Fassung einen Bund zum Verbinden mit einem Bund der Linse und eine Auflage zum Anlegen an eine geräteseitige Auflage aufweist und daß die beiden Bünde mittels Ultraschall verschweißt und dabei mit ihrem Auflagemaß gegenüber der Auflage justiert sind.A plastic lens arranged in a plastic mount using this method is characterized in that the socket has a collar for connecting to a collar the lens and a support for placing on a device-side support and that the two collars are welded by means of ultrasound and at the same time with their flange focal length are adjusted in relation to the support.
Das erfindungsgemä#e Verfahren hat gegenüber den bekannten Verfahren zur Verbindung von Kunststofflinsen mit Kunststofffassungen den Vorteil, daß die Herstellung der Verbindung und die Justierung in einem einzigen Arbeitsgang möglich sind, ohne daß Werkzeugspuren an der Linse oder der Fassung auftreten, Beilagscheiben oder Zwischenringe eingesetzt werden müssen oder Material an der Auflagefläche In der Kamera oder eines anderen Gerätes, in das die Fassung el. ng setzt werden soll, weggenommen werden mu# oder ähnliche au Justierzwecken übliche Verfahren angewendet werden müssen.The method according to the invention has advantages over the known methods for connecting plastic lenses with plastic frames the advantage that the Establishing the connection and adjustment possible in a single operation are without tool marks on the lens or the frame, washers or intermediate rings must be used or material on the contact surface In the camera or another device in which the socket el. ng is to be placed, must be removed or similar procedures usual for adjustment purposes must be used Need to become.
Die Erfindung. wird anhand einer Zeichnung näher erläutert.The invention. is explained in more detail with reference to a drawing.
Die einzige Figur zeigt eine schematische Darstellüng naah der Erfindung, teilweise im Schnitt.The only figure shows a schematic representation near the Invention, partly in section.
In der Figur ist eine aus Kunststoff bestehende Objektivfassung mit 1 und eine Linse, die aus organischem Glas besteht, mit 2 bezeichnet. Die Fassung 1 weist eine Auflage 1a und einen Bund 1b, auf welchem die Linse 2 aufliegen soll; auf.A lens mount made of plastic is shown in the figure 1 and a lens made of organic glass, denoted by 2. The version 1 has a support 1a and a collar 1b on which the lens 2 is intended to rest; on.
Da die Auflage 1a in einer fotografischen Kamera befestigt werden soll, deren Filmbahn festliegt, muß der Abstand zwischen der Auflage 1a und dem Bund 1b gleich dem Auflagemaß der Linse 2 abzüglich dem Abstand zwischen der Auflage 1a in der Kamera und der Filmbahn in der Kamera sein.Since the support 1a can be fixed in a photographic camera should, the film path is fixed, the distance between the support 1a and the Bund 1b equal to the flange focal length of the lens 2 minus the distance between the bead 1a in the camera and the film web in the camera.
Der Erfindung liegt nun die Aufgabe zugrunde, Fassung 1 und Linse 2 auf möglichst einfache Weise zu verbinden und dabei zu justieren. Zur Lösung dieser Aurgabe bietet sich das an sich bekannte Verfahren der Ultraschallverschweißung an, wobei miteinander zu verbindende Kunststoffteile mit einem Ultraschall sender bestrahlt werden und dabei ineinander verflie#en. Um nach der Erfindung jedoch eine Verformung der 1, ins e 2 selbst zu vermeiden und Linse 2 und Fassung 1 zugleich justierren zu können, ist an der Linse 2 ein Bund 2a vorgesehen,. der auf den Bund ib der Passung 1 aufgelegt wird. Die S'onotrode 3 zum Beschallen ist als Zylinderring ausgebildet, der etwa Durchmesser und breite des Bundes 2a hat, so daß die Linse 2 nur an den mit der Fassung 1 zu verschweißenden Stellen dem Ultraschall ausgesetzt wird. Außerdem ermöglicht die Ausbildung der Sonotrode 3 als Zylinderring ein Hindurchsehen duroh die Linse 2 und Sonotrode 3, insbesondere vor der Verschweißung der Linse 2 mit der Fassung 1. Mit der Sonotrode 3 wird daher ein Gerät 4 verbunden, das eine Auflage 4a für die Auflage la der Fassung 1 aufweist. Darüber hinaus ist mit dem Gerät 4 ein gegenüber der Auflage 4a justiertes Prüfgerät 5a, 5b, beispielsweise ein Autokollimator, mit einer abmessungsmäßig gegenüber der Auflage 4a der Filmbahn in der Kamera entsprechenden Ebene verbunden. Vor Verschweißen von Linse 2 und Fassung 1 wird die Fassung 1 mit der Auflage la auf die Auflage 4a gelegt. Dann wird die Linse mit ihrem Bund 2a auf den Bund ib gelegt. Zugleich wird der Kollimator 5a, 5b auf die Linse 2 seharfeingestellt. Um den DiRferenzbetrag zwischen der der Bildbahn in der Kamera entsprechenden Ebene des optischen Gerätes und der tatsächlich einzustellenden Brennebene der Linse 2 müssen die Bünde 2a, 1b beim Verschweißen abgetragen werden. Daher ist mit dem Kollimator 5a ein Anschlag 6 für die Sonotrode 3 verbunden. Ist die Brennweite der Linse 2 zu kurz, so wird der Anschlag 6 mehr in Riohtung des Pfeil es 7 verstellt als bei relativ langer Brennweite der Linse 2.The invention is based on the object, frame 1 and lens 2 to be connected in the simplest possible way and to be adjusted in the process. To solve this Aurgabe offers the known method of ultrasonic welding on, with plastic parts to be connected to one another with an ultrasonic transmitter are irradiated and merge into one another. To according to the invention, however, a Avoid deformation of 1, into e 2 itself and lens 2 and frame 1 at the same time To be able to adjust, a collar 2a is provided on the lens 2. the one on the covenant ib of fit 1 is placed. The S'onotrode 3 for sonication is a cylinder ring formed, which has approximately the diameter and width of the collar 2a, so that the lens 2 only to the one to be welded to the socket 1 Ask the ultrasound is exposed. In addition, the sonotrode 3 is designed as a cylinder ring looking through the lens 2 and sonotrode 3, especially before welding the lens 2 with the socket 1. A device 4 is therefore connected to the sonotrode 3, which has a support 4a for the support 1 a of the version 1. In addition, is with the device 4 a test device 5a, 5b adjusted with respect to the support 4a, for example an autocollimator, with a dimensionally opposite support 4a of the film web connected to the corresponding level in the camera. Before welding lens 2 and frame 1, the version 1 with the support la is placed on the support 4a. Then the Lens placed with its collar 2a on the collar ib. At the same time, the collimator 5a, 5b sharply focused on lens 2. To the amount of difference between that of the image path in the camera corresponding level of the optical device and the one actually to be set The focal plane of the lens 2, the collars 2a, 1b must be removed during welding. A stop 6 for the sonotrode 3 is therefore connected to the collimator 5a. is the focal length of the lens 2 is too short, the stop 6 is more in the direction of the Arrow 7 adjusts it than with a relatively long focal length of lens 2.
Durch die Ultraschalleinwirkung verfließen die Bünde 2a, ib miteinander, so daß sie nach dem Erstarren fest miteinander verbunden sind. Dabei wird Je nach Stellung des anschlages 6 der Bund ib gegenüber der Auflage la abgetragen. Der Bund Ib muß vor dem Verschweißen also das eigentlich erforderliche Auflagemaß übersteigen. Beim Verschweißen ist die Sonotrode 3 so lange in Betrieb, bis sie auf den Anschlag 6 trifft.Due to the action of ultrasound, the frets 2a, ib flow together, so that after solidification they are firmly connected to one another. Depending on Position of the stop 6 the Bund ib removed from the edition la. The collar Ib must therefore have the actually required flange length before welding exceed. When welding, the sonotrode 3 is in operation until it hits the stop 6.
Beim Auftreffen auf den Anschlag 6 wird ein nicht näher beschriebener Schalter betätigt, der die Sonotrode 3 abschaltet.When it hits the stop 6, it is not described in detail Actuated switch that switches off sonotrode 3.
Sind aber die Bünde 2a, ib bis zum Anschlag 6 verflossen, so ist auch die Linse 2 gegenüber ihrer Ausgangslage um den zur Scharfeinstellung auf die der Filmbahn der Kamera entaprechenden Ebene erforderlichen Betrag in Richtung des Pfeiles 7 gegenüber der Auflage ia zurüokversetzt. Somit ist es nach dem erfindungsgemäßen Verfahren möglioh, Linse und Fassung zu verschweißen und dabei zugleich zu justieren, wobei Brennweitenabwe iehungen der Linse 2 und Toleranzen an der Fassung 1 berücksichtigt werden können.But if the frets 2a, ib have flown as far as the stop 6, then it is also the lens 2 compared to its starting position around the focus on the Film path of the camera corresponding level required amount in the direction of the arrow 7 set back compared to the edition. Thus it is according to the invention Process possible to weld lens and frame and adjust them at the same time, where focal length deviations of the lens 2 and tolerances on the mount 1 are taken into account can be.
Als optisches Prüfgerät 5a, 5b kommt ein Autokollimator in Frage-, dessen paralleler Strahlengang in der Brennebene der Linse 2 bzw. in der der Filmbahn der Kamera entsprechenden reflektierenden Ebene des Prüfgerätes 5a gesammelt und in sich selbst zurückgeworfen wird. Bei Abweichungen des reflektierten Strahlengangs vom ursprünglichen Strahlengang, ist der Kollimator nicht auf die Linse scharf eingestellt. Der Verstellweg des Kollimators von der Einstellung auf die der Filmbahn entsprechenden Ebene auf die Brennebene der Linse 2 wird zur Einstellung des anschlages 6 verwendet. Natürlich wäre es aber auch möglich, in der der Filmbahn der Kamera entsprechenden Ebene des Gerätes 4 eine Mattscheibe vorzusehen und durch die Linse 2 hindurch vor dem Beschallen eine in ausreichender Entfernung aufgestellte Testwand zu beobachten. Die Mattscheibe wird dann so lange verstellt, bis das Bild der Testwand durch die Linse 2 hindurch scharf erscheint. Der Verstellweg dient wieder zur Einstellung des Anschlages für die Sonotrode 3. Es ist jedoch exakter, zur Linsenjustierung einen Kollimator zu verwenden. Es wäre aber auch möglich, eine Vorrichtung zu verwenden, die automatisdh, z. B. mittels lichtelektrischer Wandler, die Scharfeinstellung der Linse 2 registriert und bei Erreichen der Scharfeinstellung die Bewegung des Anschlages 6 stoppt.An autocollimator can be used as the optical test device 5a, 5b, its parallel beam path in the focal plane of the lens 2 or in that of the film path the reflecting plane of the test device 5a corresponding to the camera and collected is thrown back in itself. In the event of deviations in the reflected beam path from the original beam path, the collimator is not focused on the lens. The adjustment path of the collimator from the setting to that corresponding to the film path Plane on the focal plane of the lens 2 is used to set the stop 6 used. Of course, it would also be possible in the film path of the camera corresponding level of the device 4 to provide a ground glass and through the lens 2 put a test wall at a sufficient distance through it before sonication to observe. The screen is then adjusted until the picture of the test wall appears sharp through lens 2. The adjustment path is again used for setting of the stop for the sonotrode 3. However, it is more precise for lens adjustment to use a collimator. But it would also be possible to use a device the automatisdh, z. B. by means of photoelectric converters, the focus the lens 2 registered and when the focus is reached the movement of the Stop 6 stops.
Entfernungsmeßvorriohtungen, die für diesen Zweck geeignet sind, sind bereits in verschiedenen Ausführungsformen bekannt.Distance measuring devices suitable for this purpose are already known in various embodiments.
Selbstverständlich ist das erfindungsgemäße Verfahren nicht auf Kameraobgektive beschränkt, sondern auch auf ObJektive und Objektivfassungen fUr andere optische Geräte anwendbar.It goes without saying that the method according to the invention does not apply to camera objectives limited, but also to lenses and lens mounts for other optical Applicable devices.
