Abstract
Description
Die Erfindung betrifft einen Flächengreifer mit einem Gehäuse, welches an einen Manipulator, zum Beispiel an einen Roboterarm, anschließbar ist, und eine Saugseite aufweist, mit der Werkstücke ansaugbar sind, wobei an der Saugseite eine Saugplatte befestigbar ist.The invention relates to a surface gripper a housing, which is connected to a manipulator, for example a robot arm, connectable is, and has a suction side with which workpieces can be sucked in, at a suction plate can be attached to the suction side.
Aus der
Des Weiteren sind Vorrichtungen bekannt, bei denen eine Saugplatte mittels Halteklipse angeklipst werden. Diese Halteklipse umgreifen die Längsseiten des Grundkörpers, was den Nachteil hat, dass diese Grundkörper nun nicht mehr lückenlos nebeneinander gesetzt werden können.Devices are also known for which a suction plate are clipped on using clips. This Retaining clips encompass the long sides of the basic body, which has the disadvantage that these basic bodies are no longer complete can be placed side by side.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Flächengreifer bereitzustellen, bei dem die Saugplatten lediglich von unten an den Grundkörper befestigt werden und zum Befestigen und Wechseln keine Werkzeuge erforderlich sind.The invention is therefore the object based on a surface grab To provide, in which the suction plates only from below the basic body are fastened and no tools for fastening and changing required are.
Diese Aufgabe wird mit einem Flächengreifer der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass die Saugplatte über Magnetkräfte an der Saugseite des Gehäuses befestigbar ist.This task is carried out with a surface gripper initially mentioned type according to the invention solved in that the suction plate over Magnetic forces the suction side of the housing is attachable.
Dieser erfindungsgemäße Flächengreifer hat den wesentlichen Vorteil, dass zum Befestigen und zum Wechseln der Saugplatte kein Werkzeug mehr erforderlich ist, da die Haltekraft von einem oder von mehreren Magneten bereitgestellt wird. Außerdem werden die Seitenflächen des Flächengreifers nicht übergriffen, so dass mehrere Flächengreifer modulartig lückenlos nebeneinander aufgereiht werden können.This surface gripper according to the invention has the main advantage that for attaching and changing The suction plate no longer requires any tools because of the holding force is provided by one or more magnets. Also be the side faces of the area grab not attacked so multiple area grabs modularly seamless can be lined up side by side.
Bei einer Weiterbildung ist vorgesehen, dass die Saugplatte einen mehrlagigen Aufbau aufweist. Dabei dienen die Lagen unterschiedlichen Zwecken, zum Beispiel dient die eine Lage zum Befestigen der Saugplatte, wohingegen die andere Lage als Dichtmittel bezüglich des Werkstücks dient, indem diese Lage dichtend und Unebenheiten in der Oberfläche ausgleichend, am Werkstück anliegt.In the case of further training, that the suction plate has a multilayer structure. Serve the layers serve different purposes, for example one serves Position for attaching the suction plate, whereas the position other than Sealant regarding of the workpiece serves by sealing this layer and compensating for unevenness in the surface, on the workpiece is applied.
Gemäß einer Weiterbildung der Erfindung ist eine der Lagen der Saugplatte als Haltelage ausgebildet und besteht zumindest in ersten Abschnitten aus einem magnetisierten oder einem ferromagnetischen Material. Auf einfache und kostengünstige Weise wird dies dadurch bewerkstelligt, dass diese Haltelage von einem ferromagnetischen Blech (Stahlblech) gebildet wird, an welchem die Saugmatte beziehungsweise Dichtmatte befestigt ist. Dieses Blech kann als Lochblech oder Gitter ausgebildet sein.According to a development of the invention is one of the layers of the suction plate designed as a holding position and consists at least in the first sections of a magnetized or a ferromagnetic material. In a simple and inexpensive way this is accomplished by the fact that this stop position by a ferromagnetic sheet (steel sheet) is formed, on which the Suction mat or sealing mat is attached. This sheet can be designed as a perforated plate or grid.
Erfindungsgemäß besteht die Saugseite des Gehäuses zumindest in zweiten Abschnitten aus einem ferromagnetischen oder einem magnetisierten Material. Wird die Saugplatte an der Saugseite des Gehäuses befestigt, dann liegen die ersten und zweiten Abschnitte einander gegenüber, so dass die magnetischen Kräfte ihre Wirkung entfalten und die Saugplatte festhalten können.According to the invention, there is at least the suction side of the housing in second sections made of a ferromagnetic or a magnetized material. If the suction plate is attached to the suction side of the housing, then lie the first and second sections facing each other so that the magnetic personnel can take effect and hold the suction plate.
Gemäß einer Weiterbildung ist vorgesehen, dass die Haltelage zwischen einer Dichtmatte und einer Schaummatte angeordnet ist. Die Dichtmatte hat den wesentlichen Vorteil, dass sie die Funktion der Abdichtung der mehreren Ansaugöffnungen im Flächengreifer übernimmt, wodurch der Vorteil erzielt wird, dass bei angesaugtem Gegenstand die Saugplatte mit angesaugt und am Gehäuse festgehalten wird. Die Magnetkraft ist deshalb nur dann zum Halten der Saugplatte erforderlich, wenn kein Gegenstand angesaugt ist.According to a further development, it is provided that the holding position between a sealing mat and a foam mat is. The sealing mat has the main advantage that it has the function sealing the several suction openings in the area gripper, whereby the advantage is achieved that when the object is sucked in the suction plate is sucked in and held on the housing. The Magnetic force is therefore only required to hold the suction plate, if no object is sucked in.
Eine einfache Variante sieht vor, dass in die Saugseite Magnete eingelassen sind. Diese Magnete sind in ihrer Zahl so bemessen, dass die Saugplatte mit Sicherheit festgehalten wird. Dabei können preiswerte Magnete Verwendung finden, so dass auch bei einer höheren Anzahl von Magneten die Herstellungskosten des Flächengreifers nahezu unverändert bleiben.A simple variant provides that magnets are embedded in the suction side. These are magnets dimensioned in such a way that the suction plate is held securely becomes. It can be inexpensive Magnets are used so that even with a higher number of magnets the manufacturing costs of the area gripper remain almost unchanged.
Dabei können als Magnete Permanentmagnete oder Elektromagnete Einsatz finden. Wie bereits erwähnt, sind Permanentmagnete relativ preiswert, wobei bei der Verwendung von Elektromagneten eventuell ein einziger Magnet ausreicht, um die Saugplatte festzuhalten.Permanent magnets can be used as magnets or electromagnets are used. As mentioned earlier, are Permanent magnets relatively inexpensive, with the use of Electromagnets possibly a single magnet is sufficient to hold the suction plate hold.
Bei einer Weiterbildung ist vorgesehen, dass die Saugseite Querkräfte abstützende Mittel aufweist. Dabei werden die Mittel von die Saugseite übergreifenden Zapfen gebildet, die in in der Saugplatte vorgesehene Aufnahmen eingreifen.In the case of further training, that the suction side has transverse forces supporting Has means. The funds are from the suction side Cones formed in the receptacles provided in the suction plate intervention.
Hierdurch wird verhindert, dass die Saugplatte zwar festgehalten wird, aber seitlich abrutscht, falls das Werkstück einseitig gegriffen wird. Außerdem können Schwenk- und translatorische Bewegungen des Manipulators problemlos auf das Werkstück übertragen werden, ohne dass die Gefahr besteht, dass das Werkstück mit Saugplatte abrutscht.This prevents the Suction plate is held, but slips sideways if the workpiece is gripped on one side. Moreover can Swivel and translational Transfer movements of the manipulator to the workpiece without any problems without the risk that the workpiece with suction plate slip.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung ein besonders bevorzugtes Ausführungsbeispiel im Einzelnen dargestellt ist. Dabei können die in der Zeichnung dargestellten und in den Ansprüchen und in der Beschreibung erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein.Further advantages, features and details of the invention result from the following description, in which a particularly preferred embodiment with reference to the drawing example is shown in detail.
