Description
Die Schweißdrahtzuführung zum automatischen Schweißen (Robotorschweißen) mit Festkö&phgr;erlaser ist eine Vorrichtung, die sowohl die Positionierung des Lasers als auch die Positionierung des zum Schweißen automatisch und kontinuierlich zuzuführenden Schweißdrahtes beherrscht, um die spezifischen Anforderungen beim Laserschweißen zu erfüllen.The welding wire feeder for automatic welding (robot welding) with solid-state laser is a device that controls both the positioning of the laser and the positioning of the welding wire to be fed automatically and continuously for welding in order to meet the specific requirements of laser welding.
Stand der Technik ist bisher das kontinuierliche genau positonierte Zuführen von Schweiß-draht beim konventionellen MIG- und WIG-Schweißen, das prinzipiell andere Anforderungen an die Schweißdrahtzuführung stellt.The current state of the art is the continuous, precisely positioned feeding of welding wire in conventional MIG and TIG welding, which fundamentally places different demands on the welding wire feed.
Die neue Lösung stellt eine komplexe Vorrichtung, die den kontinuierlich zuzuführenden Schweißdraht in alle gewünschten Richtungen und Abstände bezüglich des Fokuspunktes des Festkörperlasers genau positioniert.The new solution is a complex device that precisely positions the continuously fed welding wire in all desired directions and distances relative to the focal point of the solid-state laser.
Bei der Positionierung (Bild 4) ist es erfolderlich, einen spezifischen Abstand bzw. eine spezielle Richtung abhängig von Fertigungsbedingungen und zu verschweißenden Materialien zwischen den beiden nachfolgend genannten Punkten auf der Werkstückoberfläche zu realisieren:When positioning (Figure 4), it is necessary to achieve a specific distance or a specific direction depending on the manufacturing conditions and the materials to be welded between the two points on the workpiece surface mentioned below:
-F= Fokuspunkt des Lasers (Zentrum)-F= focus point of the laser (center)
-P= Auftreffpunkt des Schweißdrahtes auf der Werkstückoberfläche an dem das Zuschlagmateria! mit dem übrigen zu verbindenen Material verschmilzt.-P= Impact point of the welding wire on the workpiece surface at which the additive material fuses with the remaining material to be joined.
Die komplexe Positioniervorrichtung (vergl. Bild 1 bis 3) ist gemeinsam mit dem Laser (Pos.1) an der Halterung (Pos. 17) befestigt und somit mit dem Roboterarm verbunden. Die Bewegung A wird durch einen elektromotorischen Antrieb (Pos. 5), der die Bewegung A2 ausführt, erzeugt. Die erforderliche Richtungsänderung erfolgt über eine Schnecke (Pos. 6) auf einen Zahnkranz (Pos. 4) einer Drehführung. Die Bewegung der Drehführung ist die gewünschte Bewegungsänderung A1.The complex positioning device (see Figures 1 to 3) is attached to the bracket (item 17) together with the laser (item 1) and is thus connected to the robot arm. The movement A is generated by an electric motor drive (item 5), which carries out the movement A2. The required change in direction is carried out via a worm (item 6) on a gear ring (item 4) of a rotary guide. The movement of the rotary guide is the desired change in movement A1.
An der Drehführung (vergl. Bild 2) ist eine Linearführung (Pos. 7) angeflanscht (Pos. 19). Die Linearbewegung B1 wird wiederum durch einen Elektromotor (Pos. 10) über eine Hubspindel (Pos. 9) auf ein ünearführungselement (Pos. 8) übertragen, daß den Schweißdraht in Vorschubrichtung bewegt.A linear guide (item 7) is flanged (item 19) to the rotary guide (see Figure 2). The linear movement B1 is in turn transmitted by an electric motor (item 10) via a lifting spindle (item 9) to a linear guide element (item 8) that moves the welding wire in the feed direction.
Am LinearführungseJement (Pos. 8) ist ein Klemmelement (Pos. 11) befestigt (Pos. 20), welches schließlich die Schweißdrahtführung (Pos. 3) aufnimmt.A clamping element (item 11) is attached to the linear guide element (item 8) (item 20), which ultimately holds the welding wire guide (item 3).
Das Klemmelement (Pos. 11) positientertxfie Schweifedrahtführung (Pos. 3) durch das Begrenzungseiement (Pos. 15) und den geklemmten Zahnkranz (Pos. 14) stabil. Der feste Halt der Schweißdrahtführung, wird durch die Klemmschrauben (Pos. 21, 22) ermöglicht.The clamping element (item 11) holds the welding wire guide (item 3) in position using the limiting element (item 15) and the clamped gear ring (item 14). The clamping screws (items 21, 22) ensure that the welding wire guide is held securely in place.
Die Drehbewegung C1 kann realisiert werden, wenn die Klemmschrauben (Pos. 21, 22) gelöst werden und die Stellschraube (Pos. 12) mit der Schnecke (Pos. 13) bewegt wird (Bewegung C2). Diese Bewegung wird über den Zahnkranz (Pos. 14) auf die Schweißdrahtführung (Pos. 3) übertragen. Der Drahtvorschub wird wie bei konventionellen Drahtvorschubeinheiten, die außerhalb des Roboters untergebracht sind und über die Roboterarme mehrfach flexibel umgelenkt werden, realisiert.The rotary movement C1 can be realized if the clamping screws (items 21, 22) are loosened and the adjusting screw (item 12) is moved with the worm (item 13) (movement C2). This movement is transferred to the welding wire guide (item 3) via the gear ring (item 14). The wire feed is realized in the same way as with conventional wire feed units, which are housed outside the robot and are flexibly redirected several times via the robot arms.
Durch Wechseln der Drahtführungselemente (Pos. 16), die unterschiedliche Radien R in der Führung des Drahtes aufweisen, kann der in Bild 1 dargestellte Positionierwinkel D geändert werden. Der Winkel zwischen dem Schweißdraht und der Werkstückoberfläche kann somit zwischen 6° und 21° variiert werden.By changing the wire guide elements (item 16), which have different radii R in the guide of the wire, the positioning angle D shown in Figure 1 can be changed. The angle between the welding wire and the workpiece surface can thus be varied between 6° and 21°.
