Abstract
Description
Die Erfindung betrifft ein Verfahren für die Fertigung mit Hilfe von Robotern sowie einen Transportroboter, der zum Einsatz in einem solchen Verfahren geeignet ist.The The invention relates to a method for the production with the aid of Robots and a transport robot, which are used in one suitable for such processes.
Der Einsatz derartiger Transportroboter wird in zunehmendem Maße anstelle von fest installierten Förderanlagen in Betracht gezogen, um Fertigungsstationen mit zu bearbeitenden Werkstücken zu versorgen.Of the Use of such transport robots is increasingly taking place of permanently installed conveyor systems considered to work with manufacturing stations workpieces to supply.
Wenn ein Werkstück an einer solchen Fertigungsstation unter Ausübung einer Kraft auf das Werkstück bearbeitet werden soll, so ist dies nur mit einer geeigneten Fixierung des Werkstückes möglich. Die Fixierung des Werkstücks mit Hilfe von Fixierungsmitteln der Fertigungsstation erfordert eine Übergabe des Werkstücks von einem Transportroboter, der es herangeschafft hat, an die Fertigungsstation vor der Durchführung des Fertigungsschritts und eine erneute Übergabe des bearbeiteten Werkstücks an den gleichen oder einen anderen Transportroboter zur Weiterbeförderung des Werkstücks nach der Bearbeitung.If a workpiece machined at such a manufacturing station while exerting a force on the workpiece This is only with a suitable fixation of the workpiece possible. The fixation of the workpiece with the help of fixing the production station requires a handover of the workpiece from a transport robot who brought it to the manufacturing station before the implementation of the manufacturing step and a renewed transfer of the machined workpiece to the same or another transport robot for onward transport of the workpiece after processing.
Um derartige Übergabevorgänge ausführen zu können, muss entweder der Transportroboter oder die Fertigungsstation mit geeigneten Werkzeugen zum Handhaben des Werkstücks ausgestattet sein, die die Fertigungsstation oder den Transportroboter verkomplizieren und verteuern; außerdem erfordern die eventuell mit hoher Präzision auszuführenden Übergabevorgänge eine beträchtliche Zeit, die die Effektivität der Fertigung beeinträchtigt.Around to perform such transfer operations can, must be either the transport robot or the manufacturing station with suitable tools for handling the workpiece to be equipped complicate the manufacturing station or transport robot and more expensive; Furthermore require the possibly with high precision to carry out a transfer operations considerable Time, the effectiveness affected the production.
Aus
Aufgabe der vorliegenden Erfindung ist, ein Fertigungsverfahren und einen Transportroboter für ein solches Verfahren zu schaffen, die eine schnelle und präzise Fertigung ermöglichen.task The present invention is a manufacturing method and a Transport robot for one to create such a process, which allows fast and accurate production enable.
Die Aufgabe wird zum einen gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1 und einen Transportroboter mit den Merkmalen des Anspruchs 7 oder 9.The Task is solved on the one hand by a method having the features of claim 1 and a Transport robot with the features of claim 7 or 9.
Der Erfindung liegt zunächst die Idee zugrunde, die zeitraubende Übergabe eines Werkstücks vom Transportroboter an die Bearbeitungsstation dadurch überflüssig zu machen, dass das Werkstück auch während des von der Station durchzuführenden Fertigungsschritts von dem Transportroboter gehalten bleibt, der es zu der Bearbeitungsstation gebracht hat.Of the Invention is initially based on the idea, the time-consuming transfer of a workpiece from Transport robot to the processing station thereby unnecessary make that piece too while of the manufacturing step to be performed by the station is held by the transport robot, which it to the processing station has brought.
Herkömmliche Knickarmroboter, bei denen eine Beweglichkeit eines freien Endes in mehreren Freiheitsgraden dadurch erreicht wird, dass mehrere jeweils durch Gelenke verbundene Armstücke „in Reihe" montiert sind, sind zu diesem Zweck nicht sehr gut geeignet. Einerseits sind Knickarmroboter sehr schwer, wodurch sich für die mobile Robotik ein ungünstiges Nutzlastverhältnis ergibt. Andererseits erreichen Knickarmroboter, dadurch dass die Armstücke und die Gelenke zwischen ihnen durch eine auf das freie Ende des Arms wirkende Kraft biegebelastet werden, nicht die erforderliche Steifigkeit, die erforderlich ist, um ein Werkstück während des Fertigungsschritts entgegen einer eventuell variablen, von der Fertigungsstation ausgeübten Kraft exakt in Position zu halten. Eine Konstruktion mit mehreren, im weiteren Sinne „parallel" montierten Linearstellgliedern, wie in dem genannten US-Patent beschrieben, erreicht ein hohes Maß an Steifigkeit mit geringem Aufwand, da die einzelnen Stellglieder nur Zug- oder Druckkräften ausgesetzt sind. Hierbei sind alternativ zu der im US-Patent gezeigten Hexapod-Konstruktion auch Anordnungen möglich, welche sich insbesondere in der Anzahl der verwendeten Linearstellglieder unterscheiden.conventional Articulated robots, where a mobility of a free end achieved in several degrees of freedom, that several each Arms connected by joints are mounted "in series" not very suitable for this purpose. On the one hand articulated robots are very hard, which makes up for the mobile robotics an unfavorable payload ratio results. On the other hand reach articulated robot, thereby that the arm pieces and the joints between them through one on the free end of the Arms acting force are flexed, not the required Stiffness required to hold a workpiece during the manufacturing step against a possibly variable force exerted by the production station to hold exactly in position. A construction with several, in other meaning "parallel" mounted linear actuators, as described in said US patent achieves a high degree of rigidity with little effort, since the individual actuators only train or compressive forces are exposed. Here, as an alternative to that shown in the US patent Hexapod design also arrangements possible, which in particular in the number of linear actuators used differ.
Zweckmäßigerweise wird der gleiche Transportroboter, der ein Werkstück zu der Bearbeitungsstation geschafft und während der Bearbeitung gehalten hat, auch zum Weitertransport des Werkstücks nach der Bearbeitung eingesetzt.Conveniently, is the same transport robot, which is a workpiece to the Machining station managed and held during processing has also been used for further transport of the workpiece after processing.
Dieser Weitertransport kann zu einer zweiten Bearbeitungsstation führen, wo der Transportroboter abermals dazu dient, das Werkstück während der Bearbeitung zu halten.This Further transport may lead to a second processing station where the transport robot again serves to the workpiece during processing to keep.
Vor der Bearbeitung wird zweckmäßigerweise eine tatsächliche Stellung des Werkstücks erfasst und mit einer erwarteten Bearbeitungsstellung verglichen. Im Falle einer Abweichung zwischen tatsächlicher und erwarteter Stellung wird die tatsächliche Stellung mit Hilfe der Linearstellglieder korrigiert.In front the processing is expediently an actual Position of the workpiece recorded and compared with an expected processing position. In case of a difference between actual and expected position becomes the actual position corrected with the help of linear actuators.
Um die Erfassung durchzuführen, ist der Transportroboter erfindungsgemäß vorzugsweise mit einem Umgebungssensor ausgestattet. Bei dem Umgebungssensor kann es sich beispielsweise um einen Triangulationssensor, Laserscanner oder eine Kamera handeln, welche 2D- oder 3D-Daten erfasst. Hierbei ist der jeweilige Umgebungssensor vorzugsweise mit einem Prozessor des Transportroboters verbunden und erfasst die tatsächliche Stellung des Werkstücks. Ein solcher Umgebungssensor kann dem Transportroboter auch dazu dienen, die Position eines Referenzmerkmals der Bearbeitungsstation zu erfassen und das Werkstück in Bezug auf dieses Referenzmerkmal in eine vorgegebene, für die durchzuführende Bearbeitung geeignete Stellung zu bringen.In order to perform the detection, the transport robot according to the invention is preferably equipped with an environmental sensor. The environment sensor may be, for example, a triangulation sensor, a laser scanner or a Acting camera that captures 2D or 3D data. Here, the respective environmental sensor is preferably connected to a processor of the transport robot and detects the actual position of the workpiece. Such an environmental sensor may also serve the transport robot to detect the position of a reference feature of the processing station and to bring the workpiece with respect to this reference feature in a predetermined, suitable for the processing to be performed position.
Umgekehrt kann ein solcher Umgebungssensor auch Teil der Fertigungsumgebung sein, in der der Transportroboter arbeitet, und der Transportroboter verfügt über Kommunikationsmittel, die es ihm ermöglichen, die Erfassungsergebnisse des Umgebungssensors abzufragen und für seine Steuerung zu nutzen.Vice versa Such an environmental sensor may also be part of the manufacturing environment be in which the transport robot works, and the transport robot has communication tools, that enable him to query the detection results of the environmental sensor and for his To use control.
