Abstract
Description
Die Erfindung bezieht sich auf eine nicht lösbare Laserschweißverbindungsanordnung zwischen einem flach ausgebildeten Stanzgitter und einer nahezu senkrecht zur Längserstreckung des Stanzgitters ausgebildeten Stifts, wobei das Stanzgitter Bohrungen in der Ausbildung von Stanzgitteraugen zur Auflage auf dem Stift aufweist und die Erfindung betrifft ein Verfahren zur Herstellung einer nicht lösbaren Schweißverbindung zwischen einem flachausgebildeten Stanzgitter und einem nahezu senkrecht zur Längserstreckung des Stanzgitters ausgebildeten Stift.The invention relates to a not solvable Laser welded joint arrangement between a flat lead frame and an almost perpendicular to the longitudinal extension of the lead frame formed pin, the lead frame holes in the formation of leadframe eyes to rest on the pen has and the invention relates to a method for manufacturing one cannot be solved welded joint between a flat lead frame and an almost vertical one for longitudinal extension of the lead frame trained pin.
Stanzgitter der vorliegenden Art sind in vielfältigen Ausführungen bekannt. Sie sind hierfür vorgesehen, um Anschlüsse für beispielsweise Wegsensoren, Drehzahlsensoren, insbesondere im Automobilbe reich über längere Strecken zu einer Steuerelektronik herzustellen. Diese Stanzgitter weisen mehrere elektrische Ladebahnen auf und werden in der Regel durch einen Stanzvorgang hergestellt.Punching grid of the present type are in diverse versions known. You are for this provided to connections for example Displacement sensors, speed sensors, especially in the automotive area over long distances to manufacture control electronics. These lead frames show several electric charging tracks on and are usually through made a punching process.
Um diese Stanzgitter zu fixieren, sind sogenannte Stanzgitteraugen vorgesehen, die mit Stiften, die in den Gehäusen angeordnet sind, verbunden werden. Die Stanzgitteraugen sind auf der Stirnseite der Stifte der Steuerelektronik flach ausgebildet und werden ungefähr mittig aufgelegt und dort lasergeschweißt. Der Laserstrahl selbst trifft unmittelbar auf das Stanzgitterauge, wodurch ein vollständiges Aufschmelzen der vollen Blechdicke des Stanzgitters notwendig ist, damit die aufgebrachte und eingekoppelte Schweißenergie den darunter liegenden Stift aus Metall erreicht und diesen in seinen Kernzonen anschmelzt. Die beiden in Schmelze befindlichen Stanzgitter bzw. Stift vereinigen sich nach dem Abschalten des Laserstrahls bzw. Auskühlen der Schmelze.To fix this lead frame, so-called punched grid eyes are provided, which with pins that in the housings are arranged to be connected. The leadframe eyes are open the end face of the pins of the control electronics flat and become roughly placed in the middle and laser welded there. The laser beam itself strikes the lead frame eye, causing a complete melting the full sheet thickness of the lead frame is necessary so that the applied and coupled welding energy the underlying Metal pin reached and melted in its core zones. Combine the two lead frames or pins in the melt after switching off the laser beam or cooling the melt.
Nachteile des Standes der Technikdisadvantage the state of the art
Ein wesentlicher Nachteil des Standes der Technik ist, dass zur Herstellung dieser nicht lösbaren Laserschweißverbindung sehr viel Schweißenergie notwendig ist, um zunächst das Stanzgitter und anschließend auch die stiftartige Ausbildung aufzuschmelzen.A major disadvantage of the stand The technology is that to produce this non-detachable laser welded connection a lot of welding energy is necessary to initially the lead frame and then also melting the pencil-like training.
Aufgabe der ErfindungObject of the invention
Lösung der AufgabeSolution of task
Der Kerngedanke der Lösung der Aufgabe besteht darin, den Laserstrahl derart einzukoppeln, dass ausschließlich der die zum Stift hinweisende Randzone der Innenwandung der Bohrung des Stanzgitters zusammen mit dem Stift aufgeschmolzen wird, so dass es nicht mehr notwendig ist, die gesamte Blechdicke des Stanzgitters mit aufzuschmelzen.The main idea of the solution of The task is to couple the laser beam in such a way that exclusively the edge zone of the inner wall of the bore pointing towards the pin the lead frame is melted together with the pin, so that the entire sheet thickness of the lead frame is no longer necessary to melt with.
Vorteile der ErfindungAdvantages of invention
Der wesentliche Unterschied zu dem bereits im Stand der Technik bekannten Verfahren besteht darin, dass die Bohrungen im Stanzgitterauge einige Zehntel mm kleiner sind als der Außendurchmesser des Außenstiftes, so dass es zu einer flächigen Auflage vorzugsweise auf der Stirnseite des Stifts kommt.The main difference to that Methods already known in the prior art consist in that the holes in the lead frame eye are a few tenths of a millimeter smaller are considered the outside diameter of the External pin, making it a flat Pad preferably comes on the face of the pen.
Zur Herstellung der nicht lösbaren Schweißverbindung wird die Laseroptik vorzugsweise mittig zur jeweiligen Bohrung im Stanzgitterauge ausgerichtet. Die Einstellung des Laserstrahls (Fokus-Abstand) wird derart gewählt, dass nur eine Randzone der Bohrungsinnenwand in Richtung Stirnseite des Stifts aufgeschmolzen wird. Durch die Anordnung des Laserstrahls bzw. dessen Fokussierung oberhalb des Stanzgitters wird auch erreicht, dass eine ringförmige Verbindungsanordnung entsteht, die eine wesentlich höhere mechanische Festigkeit als eine Punktschweißverbindung aufweist.To create the non-releasable weld connection the laser optics is preferably centered on the respective hole in the Lead eye aligned. The setting of the laser beam (focus distance) becomes like this selected that only one edge zone of the bore inner wall towards the front of the pin is melted. By arranging the laser beam or its focusing above the lead frame is also achieved, that an annular Connection arrangement arises, which is a much higher mechanical Strength as a spot weld joint having.
Ein weiterer wesentlicher Vorteil der Erfindung besteht darin, dass sich die Schmelzen beider Teile sehr einfach vereinigen können, da sie innerhalb der Bohrungstiefe des Stanzgitterauges gefangen sind (aufgrund der des Abschlusses der Bohrung durch den Stift).Another major advantage The invention is that the melting of both parts can unite very easily since they are caught within the hole depth of the lead frame eye (due to the completion of the hole by the pin).
Vorzugsweise ist die Bohrung im Stanzgitterauge gestanzt, so dass eine gleichmäßige Einkupplung des Laserstrahls erfolgen kann, wodurch wiederum eine hohe Gleichmäßigkeit der Schweißparameter erreicht wird.The bore is preferably in the lead frame eye punched so that an even engagement of the laser beam can take place, which in turn ensures high uniformity the welding parameter is achieved.
Die Ebenheit des Stanzgitterauges ist von geringer Bedeutung, ebenso die Beschaffenheit der Oberfläche des Stanzgitters.The flatness of the lead frame eye is of little importance, as is the nature of the surface of the Stamped grid.
