Der sechste Freiheitsgrad kann nicht erfaßt werden.In US-PS 43 16 329 is an optoelectronic Measuring arrangement with one or more light sources and analogue, position-sensitive receiving diodes as a signal generator to describe the location of a Measuring body in one of two coordinate axes and up existing five-dimensional to three angles of rotation Coordinate system described. However, as from the Description emerges, the system is based on five Degrees of freedom limited. The sixth degree of freedom cannot be recorded.

Der Erfindung liegt daher die Aufgabe zugrunde, eine optoelektronische Meßanordnung zu schaffen, mit der die Lage des Meßkörpers in sechs Dimensionen, nämlich in drei Translations- und drei Rotationsdimensionen, angebbar ist.The invention is therefore based on the object To create optoelectronic measuring arrangement with which the Position of the measuring body in six dimensions, namely in three translation and three rotation dimensions, can be specified is.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß an dem Referenzkörper drei, jeweils zweidimensional messende und durch ihre Flächennormale ein räumliches Koordinatensystem aufspannende positionsempfindliche Empfangsdioden angeordnet sind, auf die im Ruhezustand der Meßanordnung vom Meßkörper aus drei Lichtbündel senkrecht gerichtet sind und aus deren Signalpaaren sechs Lagesignale entsprechend den sechs Freiheitsgraden des Meßkörpers angebbar sind.This object is achieved according to the invention in that on the reference body three, each two-dimensional measuring and spatial due to its surface normal Coordinate system spanning position sensitive Receiving diodes are arranged on the at rest of the Measuring arrangement from the measuring body from three light beams perpendicular are directed and from their signal pairs six position signals corresponding to the six degrees of freedom of the measuring body can be specified.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend an Hand der Zeichnung näher beschrieben. Es zeigtAn embodiment of the invention is described below with reference to Drawing described in more detail. It shows

Fig. 1 eine Prinzipdarstellung von Sende- und Empfangsdioden, und Fig. 1 shows a schematic diagram of transmit and receive diodes, and

Fig. 2 eine vereinfachte Darstellung einer Meßanordnung. Fig. 2 is a simplified representation of a measuring arrangement.

In der Prinzipdarstellung der Fig. 1 senden drei Sendedioden 1, die räumlich gleichmäßig voneinander angeordnet sind, je einen Lichtstrahl 2 einer kohärenten Lichtquelle - beispielsweise einer Laserlichtquelle - auf jeweils gegenüberliegend angebrachte Empfangsdioden 3. Die Lichtstrahlen 2 sind durch Linsen 4 so fokussiert, daß sie auf den Empfangsdioden 3 einen scharf begrenzten Lichtpunkt 5 erzeugen. Die Empfangsdiode 3 weist eine senkrecht zum Lichtstrahl 2 ange­ ordnete Empfangsfläche 6 auf. Im Ruhezustand der Anordnung ist der Lichtpunkt 5 in der Mitte der Fläche 6, die Nullpunkt eines gedachten Koordinatensystems mit der Abszisse x und der Ordinate y ist. Die Bestimmung des Ortes des Lichtpunktes 5 im Koordinatensystem kann z. B. so durchgeführt werden, daß der Stromverlauf über die Fläche 6 gemessen und integriert wird, wodurch eine Schwerpunktsbestimmung der Ausleuchtung erfolgt. . In the schematic diagram of Figure 1 to send three transmitting diodes 1 arranged spatially uniform another, are each a light beam 2 of a coherent light source - for example, a laser light source - in each case oppositely brought receiving diodes 3. The light beams 2 are focused by lenses 4 so that they produce a sharply delimited light spot 5 on the receiving diodes 3 . The receiving diode 3 has a receiving surface 6 arranged perpendicular to the light beam 2 . When the arrangement is at rest, the light point 5 is in the middle of the surface 6 , which is the zero point of an imaginary coordinate system with the abscissa x and the ordinate y . The determination of the location of the light point 5 in the coordinate system can, for. B. be carried out so that the current profile over the surface 6 is measured and integrated, thereby determining the center of gravity of the illumination.

In der vereinfacht dargestellten praktischen Ausführungsform einer Meßanordnung 10 sind drei Sendedioden 1 auf dem Mantel eines Meßkegels 11, der einen Kegelwinkel von 90° aufweist, so angeordnet, daß sie auf einer zu der Grundfläche des Kegels 11 parallelen Ebene 11 a in glei­ chen Abständen liegen. Die Achsen der Sendedioden 1 treffen sich dabei in einem Punkt 11 b auf der Kegelachse 11 c. Gegenüber den Sendedioden 1 sind die Empfangsdioden 3 an einem Meßkäfig 12 angebracht, der den Meßkegel 11 umschließt. Der Meßkegel 11 wird durch sowohl am Meßkä­ fig 12 als auch am Meßkegel 11 befestigte, die Sendedioden 1 und die Empfangsdioden 3 umhüllende Federbälge 13 elastisch in annähernder Null­ lage gehalten. In der Gesamtdarstellung der Meßanordnung 10 in der Fig. 2 ist eine der Meßkomponenten, bestehend aus der Sendediode 1, der Empfangsdiode 3 und dem Federbalg 13, der Anschaulichkeit halber um 60° versetzt dargestellt. In the simplified practical embodiment shown of a measuring arrangement 10 are three transmit diode 1 on the jacket of a Meßkegels 11 having a cone angle of 90 °, so arranged as to a lie in sliding surfaces intervals on a plane parallel to the base of the cone 11 Level 11 . The axes of the transmitter diodes 1 meet at a point 11 b on the cone axis 11 c . Compared with the transmitting diodes 1, the receiving diodes 3 are mounted on a measuring cage 12 which surrounds the measuring cone. 11 The measuring cone 11 is held by both on the Meßkä fig 12 and on the measuring cone 11 , the transmitting diodes 1 and the receiving diodes 3 enveloping bellows 13 elastically held in approximately zero position. In the overall representation of the measuring arrangement 10 in FIG. 2, one of the measuring components, consisting of the transmitter diode 1 , the receiver diode 3 and the bellows 13 , is shown offset by 60 ° for the sake of clarity.

Die Meßanordnung wird von einem allseitig bewegbaren Handhabungsge­ rät 14 gehalten, das mit Greifern 15 a einer Kupplung 15 einen hinte­ ren Flansch 11 d des Meßkegels 11 umfaßt. Zur Vermeidung von Beschädi­ gungen der Meßanordnung 10 beim automatischen Heranfahren der Greifer 15 a an den Flansch 11 d ist an dem Meßkäfig 12 ein Schutzring 9 ange­ setzt, der mit einem Labyrinth zur Positionseinfädelung versehen ist und der bei Berührung durch den Greifer 15 a eine Stromunterbrechung in der Steuerung des Handhabungsgerätes 14 veranlaßt. Wenn nun bei der Überprüfung des Referenzpunktes oder bei einer Fehlersuche in der Steuerung des Handhabungsgerätes 14 der Meßkegel 11 sich außerhalb der Nullage befindet, treffen die Lichtstrahlen 2 von einer oder meh­ reren Sendedioden 1 nicht mehr auf den Koordinatenmittelpunkt der Fläche 6 der zugehörigen Empfangsdioden 3. Es werden dann Signale von den Empfangsdioden 3 über Leitungen 16 zu einer Auswerteeinheit 17 übertragen und je Empfangsdiode 3 zu x-, y-Koordinaten entspre­ chend der Stellung des jeweiligen Lichtpunktes 5 auf der Fläche 6 um­ gewandelt (siehe auch Fig. 1). Die ermittelten x-, y-Koordinaten werden daraufhin an einen Auswerterechner 18 übertragen, der aus dem durch die Koordinaten x und y gegebenen Istzustand der Stellungen der Sendedioden 1 Translationsvektoren für eine Koordinaten-Korrektur er­ mittelt und die Korrekturwerte über eine Leitung 22 in eine Steuer­ einheit 21 eingibt, die die Kupplung 15 über eine Leitung 23 und von dieser über mechanische Mittel zu einer Korrekturbewegung des Meß­ kegels 11 veranlaßt. Dieser Korrekturvorgang wiederholt sich so oft, bis die exakte Nullage des Meßkegels 11 oder zumindest ein vorge­ gebenes Toleranzfeld um die Nullage erreicht ist. Die Sendedioden 1 können auch von einer in der Greiferkupplung 15 angeordneten kohärenten Lichtquelle 20 ersetzt werden.The measuring arrangement is advised by a manipulator 14 which can be moved on all sides and which, with grippers 15 a of a coupling 15, comprises a rear flange 11 d of the measuring cone 11 . To avoid damage to the measuring arrangement 10 during the automatic approach of the gripper 15 a to the flange 11 d , a protective ring 9 is placed on the measuring cage 12 , which is provided with a labyrinth for threading the position and which has a current interruption when touched by the gripper 15 a caused in the control of the handling device 14 . If the measuring cone 11 is now outside the zero position when checking the reference point or when troubleshooting the control of the handling device 14 , the light beams 2 from one or more transmitting diodes 1 no longer strike the coordinate center of the surface 6 of the associated receiving diodes 3 . Signals are then transmitted from the receiving diodes 3 via lines 16 to an evaluation unit 17 and converted for each receiving diode 3 to x, y coordinates corresponding to the position of the respective light spot 5 on the surface 6 (see also FIG. 1). The determined x, y coordinates are then transmitted to an evaluation computer 18 , which determines translation vectors for a coordinate correction from the actual state of the positions of the transmitter diodes 1 given by the coordinates x and y , and the correction values via a line 22 into a control Unit 21 enters the clutch 15 via a line 23 and from this via mechanical means for a corrective movement of the measuring cone 11 . This correction process is repeated until the exact zero position of the measuring cone 11 or at least a pre-given tolerance range around the zero position is reached. The transmission diodes 1 can also be replaced by a coherent light source 20 arranged in the gripper coupling 15 .
