Abstract

Handteil zum manuellen Laserschweißen, dadurch gekennzeichnet, dass das Handteil mit einer Vorrichtung für den automatischen Vorschub des Handteils ausgestattet ist, die für eine gleichmäßige Bewegung des Handteils auf der Werkstückoberfläche und für einen konstanten Abstand zwischen Handteil-Laserobjektiv und Werkstückoberfläche sorgt.Handpiece for manual laser welding, characterized in that the handpiece is equipped with a device for automatic feeding of the handpiece, which ensures a smooth movement of the handpiece on the workpiece surface and for a constant distance between the handpiece laser lens and the workpiece surface.

Description

Stand der Technik:State of the art:

Es ist bekannt, Lasersysteme mit flexiblem Handteil zum manuellen Laserschweißen einzusetzen.It is known to use laser systems with a flexible handpiece for manual laser welding.

Problem:Problem:

Der vorliegenden Erfindung liegt folgendes Problem zugrunde:
Beim automatisierten Schweißprozess (z. B. von Karosserieteilen) entstehen gelegentlich Fehlstellen, die (vor Ort) repariert werden müssen. D. h. die in der Schweißnaht entstandenen Fehlstellen (z. B. Lücken, Poren, Durchschüsse oder versetzten Nähte) müssen manuell nachgeschweißt werden, da ein automatisches Schweißen der Fehlstellen aus Kostengründen nicht vertretbar ist.The present invention is based on the following problem:
The automated welding process (eg of body parts) occasionally causes defects that have to be repaired (on site). Ie. the defects in the weld (eg gaps, pores, bullet holes or staggered seams) must be rewelded manually, as automatic welding of the defects is not justifiable for cost reasons.

Für diese manuellen Schweißarbeiten wird ein Handschweißlaser nach dem Vorbild einer Heißklebepistole benötigt, d. h. ein Lasergerät mit besonders leichtem, flexiblem Handteil, das am Einsatzort die Reparaturschweißung in optimaler Qualität durchführt.For these manual welding work, a manual welding laser is needed, similar to a hot glue gun, i. H. a laser device with a particularly light, flexible handpiece, which performs the repair welding in optimum quality on site.

Bei diesem Bearbeitungsprozess besteht das Problem insbesondere darin, das Schutzgas und den Schweißdraht gezielt an die Bearbeitungsstelle auf dem Werkstück zu führen, das Handteil in einem konstanten Abstand zum Werkstück zu führen, und dem Benutzer durch gute Sichtkontrolle in 3D-Qualität und durch gute Handhabbarkeit des Handteils die Ausführung optimaler Schweißnähte zu ermöglichen.In this machining process, the problem is in particular to guide the protective gas and the welding wire targeted to the processing point on the workpiece, to guide the handle at a constant distance from the workpiece, and the user through good visual control in 3D quality and good handling of the Handpiece to allow the execution of optimal welds.

Lösung:Solution:

Diese Probleme werden durch die in den Patentansprüchen 1–5 aufgeführten Merkmale gelöst.These problems are solved by the features listed in the claims 1-5.

Erreichte Vorteile:Achieved benefits:

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass sich das Handteil während des Schweißvorgangs automatisch mit konstantem Abstand zum Werkstück und in konstanter Geschwindigkeit fortbewegt und der Schweißdraht dabei automatisch zugeführt wird. Außerdem wird das benötigte Schutzgas automatisch über eine Düse im Handteil direkt an die Schweißstelle zugeführt. Zudem kann das Handteil zur Visualisierung des Schweißvorgangs an eine 3D-Brille (siehe Patent mit Aktenzeichen 10 2014 017 835.8) angeschlossen werden. Die dreidimensionale Darstellung hat den Vorteil, dass Erhöhungen und Vertiefungen am Werkstück für den Benutzer deutlicher zu erkennen sind, als bei einer zweidimensionalen Darstellung.The advantages achieved by the invention are in particular that the handpiece moves automatically during the welding process at a constant distance from the workpiece and at a constant speed and the welding wire is thereby automatically supplied. In addition, the required protective gas is supplied automatically via a nozzle in the handle directly to the weld. In addition, the handpiece for visualizing the welding process to a 3D glasses (see patent with file number 10 2014 017 835.8) can be connected. The three-dimensional representation has the advantage that elevations and depressions on the workpiece are more clearly recognizable to the user than with a two-dimensional representation.

Ausführungsbeispiel:Embodiment:

In 1 ist ein Ausführungsbeispiel der Erfindung dargestellt, das im Folgenden erläutert wird.In 1 an embodiment of the invention is shown, which will be explained below.

1. zeigt einen Benutzer mit Handteil (2), 3D-Brille (12) und Laserversorgungeinheit (13). 1 , shows a user with handset ( 2 ), 3D glasses ( 12 ) and laser supply unit ( 13 ).

Das Handteil ist über Kabel (1) mit der Laserversorgungeinheit (13) und der 3D-Brille (12) verbunden.The handpiece is via cable ( 1 ) with the laser supply unit ( 13 ) and the 3D glasses ( 12 ) connected.

Um den Schweißvorgang zu starten, legt der Benutzer das Handteil (2) auf das Werkstück (8) und betätigt die Start-Taste (10). Während des Schweißvorgangs tritt der Laserstrahl (5) auf das Werkstück, und das Handteil wird automatisch mit konstantem Abstand und voreingestellter Geschwindigkeit mittels Handteil-Vorschub (7) über das Werkstück bewegt. Während des Schweißvorgangs werden Schweißdraht und Schutzgas automatisch durch eine Düse (6) an die Bearbeitungsstelle geführt. Die im Handteil integrierte 3D-Kamera (9) überträgt die bewegten Bilder der Schweißstelle in Echtzeit und mit dem gewünschten Vergrößerungsfaktor in die 3D-Brille (12) des Benutzers, dessen Augen durch die Brille vor der Laserstrahlung geschützt sind.To start the welding process, the user places the handpiece ( 2 ) on the workpiece ( 8th ) and press the start button ( 10 ). During the welding process, the laser beam ( 5 ) on the workpiece, and the handpiece is automatically moved with constant distance and preset speed by means of handpiece feed ( 7 ) moves over the workpiece. During the welding process, welding wire and inert gas are automatically passed through a nozzle ( 6 ) led to the processing station. The 3D camera integrated in the handpiece ( 9 ) transfers the moving images of the weld in real time and with the desired magnification factor into the 3D glasses ( 12 ) of the user whose eyes are protected by the glasses from the laser radiation.

Über Regler am Handteil können Durchmesser des Laserstrahls (3) und die Einstellungen für die Schweißdrahtzufuhr und den automatischen Vorschub (11) reguliert werden.The diameter of the laser beam ( 3 ) and the settings for the welding wire feed and the automatic feed ( 11 ) are regulated.

Über die motorische Fokusverstellung (Autofokus) (4) wird der Abstand zwischen Laserobjektiv und Werkstück geregelt.About the motor focus adjustment (Autofocus) ( 4 ) controls the distance between the laser lens and the workpiece.
