Der Cobot als flexibler Schweißer

von Dagmar Dieterle

Cobots sind sicher, kompakt und flexibel. Zudem liefern sie in Kombination mit intelligentem Schweißequipment perfekte und jederzeit wiederholbare Schweißnähte. Fronius Perfect Welding stattet den kollaborativen Helfer mit einer Sicherheitseinhausung, einem Schweißtisch sowie einer Schweißrauchabsaugung aus und ergänzt ihn um Schweißstromquelle und Brenner. Spezielle Kenntnisse zum Programmieren der Schweißabläufe sind für die exklusiv in Deutschland erhältliche Fronius SmartCell nicht notwendig.

Das „Teachen“ des Cobots geht schnell: Im ersten Schritt bewegt der Bediener den am Roboterarm montierten Brenner manuell zu den gewünschten Punkten. Per Tastendruck speichert er die Start- und Endpunkte sowie die einzelnen Positionspunkte für den Schweißvorgang ab und übermittelt sie an das Schweißprogramm. Ist der Cobot einmal programmiert, schweißt er Bauteil für Bauteil in gleicher Qualität. Das Bestücken sowie das Starten der Schweißprogramme erfolgen nach wie vor manuell.

Die SmartCell ist dank der SmartArc-Benutzeroberfläche leicht und intuitiv bedienbar. Zentrales Steuerungs- und Bedienelement ist der SmartArc Extension Pack-Handgriff am Roboterarm. Um den Schweißprozess zu beschleunigen, hält ein Wendepositionierer das Bauteil in verschiedenen Positionen fest, so dass das Umspannen entfällt. Auch das Assistenzsystem WireSense spart Zeit: Es tastet das Werkstück vor dem Schweißen punktgenau ab und liefert dem Roboter damit die aktuelle Bauteilposition.

Parameter auf Knopfdruck

Mit der WeldConnect-App unterstützt Fronius den Bediener beim Finden der Schweißparameter. Schritt für Schritt erfragt die Anwendung Verfahren, Grundmaterial, Nahtform und Schutzgas ab. Nach der Eingabe berechnet der „Wizard“ die optimalen Parameter. Doch die Applikation für Smartphone und Tablet kann noch mehr: Sie kommuniziert drahtlos mit verbundenen Schweißsystemen. So kann der Nutzer Jobs abrufen, bearbeiten, speichern und teilen. Zudem zeigt die WeldConnect-App Informationen zum Schweißgerät wie Seriennummer, IP-Adresse, Status oder die Softwareversion.
