Abstract
Description
Zur Laserbearbeitung einer Oberfläche, z. B. Beschriften oder Nahtlöten, wird der Strahl berührungslos entlang der gewünschten Strecke gefahren. Diese Bewegung wird in der Regel durch das Ansteuern eines XY- Tisches oder durch die Auslenkung des Laserstrahls erreicht.For laser processing a surface, e.g. B. Label or seam soldering, the beam is moved along without contact traveled the desired route. This movement is usually controlled by controlling an XY Table or by deflecting the laser beam reached.
Die auftretenden Probleme werden durch den Spalt zwischen den Fügeteilen verursacht. Selbst ein geringer Spalt kann im oberen Material zu einem Wärmestau und dadurch zur Zerschmelzung der oberen Fügeteile führen. Dieser Effekt ist bei kleineren Fügeteilen deutlicher zu beobachten.The problems that arise are caused by the gap between the parts to be joined. Even a little Gap can build up heat in the upper material and thereby melting the upper parts to be joined to lead. This effect is with smaller parts to be joined to observe more clearly.
Das Problem der schlechten thermischen Ankupplung wird durch das Zusammendrücken der Fügeteile mit der Kugel gelöst.The problem of poor thermal coupling is achieved by compressing the parts to be joined with the Ball released.
Der Vorteil dieses Verfahrens liegt darin, daß bei kontinuierlicher Bewegung des Strahls ein gleichzeitiges Zusammendrücken der Proben möglich ist. Dieses wird durch die Rollbewegung der Kugel erreicht. Der Rollwiderstand wird durch die Strömung eines Mediums reduziert. Dieses Medium kann aus Inert- oder Reaktionsgasen bestehen.The advantage of this method is that continuous movement of the beam simultaneous compression of the samples possible is. This is due to the rolling motion of the ball reached. The rolling resistance is caused by the flow of a medium reduced. This medium can be made Inert or reaction gases exist.
