Abstract
Description
Die Erfindung betrifft ein Verfahren zum Bearbeiten zumindest eines Werkstücks nach dem Oberbegriff von Patentanspruch 1.The invention relates to a method for processing at least one workpiece according to the preamble of
Ein solches Verfahren ist aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art bereitzustellen, welches eine schnelle, nebenzeitarme Bearbeitung von Werkstücken ermöglicht, für die das Klinschen eine ungeeignete Bearbeitungsmethode darstellt.The present invention has for its object to provide a method of the type mentioned above, which allows fast, low-temporal machining of workpieces for which clinching represents an inappropriate method of processing.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a method having the features of
In einem solchen Verfahren zum Bearbeiten zumindest eines Werkstücks mit einem Werkzeug wird das wenigstens eine Werkstück mittels eines Roboters kontinuierlich bewegt und das Werkzeug während der Durchführung eines Bearbeitungsvorgangs an einem Bearbeitungsort des wenigstens einen Werkstücks synchron mit dem wenigstens einen Werkstück geführt. Nach dem Bearbeitungsvorgang wird das Werkzeug relativ zu dem wenigstens einen Werkstück an einen weiteren Bearbeitungsort bewegt, wobei erfindungsgemäß vorgesehen ist, dass als Werkzeug ein Punktschweißwerkzeug eingesetzt wird.In such a method for machining at least one workpiece with a tool, the at least one workpiece is continuously moved by means of a robot and the tool is guided synchronously with the at least one workpiece during a machining operation at a machining location of the at least one workpiece. After the machining operation, the tool is moved relative to the at least one workpiece to a further processing location, wherein it is provided according to the invention that a spot welding tool is used as the tool.
Hierdurch können auch beim Punktschweißen zeitaufwendige Start-Stopp-Bewegungen des Roboters vermieden werden, was zu der gewünschten Reduktion der Nebenzeiten führt. Die Bewegungen von Werkstück und Werkzeug sowie die Bearbeitungsvorgänge am Werkstück werden hierbei durch die Steuerung zeitlich aufeinander abgestimmt. Durch die schnelle Rückpositionierung des Werkzeugs, die insbesondere durch eine Linearbewegung erfolgen soll, wird dabei die Verfahrensdurchführung beschleunigt und somit kostengünstiger ausgestaltet. Durch die schnelleren Prozessabläufe entstehen zudem Kostenvorteile, da in Fertigungslinien insgesamt weniger Arbeitszellen zum Durchführen zum Punktschweißvorgänge vorgesehen werden müssen.As a result, time-consuming start-stop movements of the robot can also be avoided during spot welding, which leads to the desired reduction of non-productive times. The movements of the workpiece and the tool as well as the machining operations on the workpiece are coordinated with each other in time by the controller. Due to the rapid repositioning of the tool, which is to take place in particular by a linear movement, while the process implementation is accelerated and thus designed more cost-effective. The faster process flows also cost advantages, since in production lines less total work cells must be provided for performing the spot welding operations.
In einer bevorzugten Ausführungsform der Erfindung wird das Werkzeug mittels eines Schlittens linear in einer Führungseinrichtung bewegt. Dies ermöglicht besonders schnelle Werkzeugbewegungen und damit eine besonders gute Nebenzeitreduktion.In a preferred embodiment of the invention, the tool is moved by means of a carriage linearly in a guide device. This allows particularly fast tool movements and thus a particularly good reduction in idle time.
Vorzugsweise wird nach Beendigung aller Bearbeitungsvorgänge an dem wenigstens einen Werkstück das Werkzeug mittels des Schlittens in eine vorgegebene Ausgangsposition zurückbewegt. Damit wird eine besonders schnelle Übergabe zwischen Bearbeitungsvorgängen von mehreren Werkstücken ermöglicht, so dass auch hier Zeiten, in denen keine tatsächliche Bearbeitung stattfindet, reduziert werden.Preferably, after completion of all machining operations on the at least one workpiece, the tool is moved back into a predetermined starting position by means of the carriage. This enables a particularly quick transfer between machining operations of several workpieces, so that here too times in which no actual processing takes place are reduced.
In weiterer Ausgestaltung der Erfindung wird während des Bearbeitungsvorgangs des wenigstens eines Werkstück durch den Roboter lediglich in derjenigen Raumrichtung bewegt, in welcher der Schlitten bewegt wird. Dies ermöglicht eine besonders einfache Synchronisierung zwischen Bewegungen des Werkstückes und Werkzeugs während des eigentlichen Bearbeitungsvorgangs.In a further embodiment of the invention is moved during the processing operation of at least one workpiece by the robot only in that spatial direction in which the carriage is moved. This allows a particularly simple synchronization between movements of the workpiece and tool during the actual machining operation.
