Description
Die Erfindung betrifft eine Ultraschall-Schweißvorrichtung gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to an ultrasonic welding apparatus according to the preamble of Claim 1.
Das Ultraschallschweißen ist ein seit langem bekanntes Fügeverfahren zur elektrischen Kontaktierung elektronischer Schaltkreise, zur Herstellung von Draht-Draht-Verbindungen sowie zur mechanischen Verbindung von massiven Kunststoff- und Metallkomponenten. Während des Schweißprozesses werden die zu verfügenden Werkstücke durch Reibungskräfte und plastische Verformung auf atomaren Abstand gebracht, so dass eine Festkörperschweißverbindung entsteht. Bei der Bearbeitung nur eines Werkstückes können die erzeugten Schwingungen auch dazu benutzt werden, das Werkstück zu verformen oder zu schneiden. Die mechanischen Schwingungen der Sonotrode werden in den bekannten Vorrichtungen von einem elektromechanischen, in der Regel aus einem piezoelektrischen Kristall bestehenden Konverter erzeugt, der von einem Ultraschallgenerator mit einem elektrischen Wechselstromkreis angeregt wird. Der Konverter schwingt dabei mit einer vorgegebenen Amplitude bei einer entsprechenden Ultraschall-Resonanzfrequenz, wobei ein typischer Wert z. B. 35 kHz für die Frequenz ist. Das aus Konverter und Sonotrode bestehende Schwinggebilde ist so eingerichtet, dass es ebenfalls in der oder nahe der Resonanzbedingung schwingt und die für die Bindungsbildung nötige Energie den zu fügenden Werkstücken zuführt. Als Gegenwerkzeug zu der Sonotrode ist ein Werkstückhalter vorgesehen, welcher gewöhnlich aus einem Amboss und einem Ambosshalter besteht, so dass sich auf das Werkstück oder die Werkstücke zwischen der Sonotrode und dem Amboss eine Klemmkraft ausüben lässt.The ultrasonic welding is a long-known joining process for electrical contacting of electronic circuits, to Production of wire-wire connections as well as mechanical connection of massive plastic and metal components. During the welding process will be the ones to have workpieces by friction forces and plastic deformation brought to atomic distance, so that a solid-state welding connection arises. When machining only one workpiece, the generated vibrations also be used to deform or cut the workpiece. The mechanical vibrations of the sonotrode are known in the art Devices of an electromechanical, usually one piezoelectric crystal existing converter generated by an ultrasonic generator with an electrical AC circuit is stimulated. The converter oscillates with a given Amplitude at a corresponding ultrasonic resonance frequency, where a typical value z. B. 35 kHz for the frequency. The end Converter and sonotrode existing vibrating structures is set up that it also vibrates in or near the resonance condition and the for the binding formation necessary Energy to be joined workpieces supplies. As a counter tool to the sonotrode is a workpiece holder which is usually provided made up of an anvil and an anvil holder, so that up the workpiece or the workpieces between the sonotrode and the anvil exert a clamping force.
Maßgebend für die Bindungsbildung während des Schweißprozesses ist die Relativbewegung zwischen den Werkstücken, der Sonotrode und dem Werkstückhalter in der Bindungsfläche, welche durch die Amplitude der Sonotrodenschwingung bestimmt wird. Aus dem Stand der Technik sind lediglich Vorrichtungen bekannt, bei welchen die mechanische Fixierung der Werkstücke über einen dynamisch passiven Werkstückhalter erfolgt, bei dessen Konstruktion man darauf abzielt, die Werkstücke möglichst stabil in einer Position zu halten. Bei diesen Vorrichtungen fließt der größte Teil der Schwingungsenergie durch die Bindungsstelle in den Werkstückhalter und weiter in dessen Verankerung und geht dadurch verloren.authoritative for the Bond formation during of the welding process is the relative movement between the workpieces, the sonotrode and the workpiece holder in the binding area, which is determined by the amplitude of the sonotrode vibration. From the prior art, only devices are known in which the mechanical fixation of the workpieces via a dynamically passive Workpiece holder takes place, the construction of which aims at the workpieces as possible stable in one position. Most of these devices flow the vibrational energy through the binding site in the workpiece holder and further in its anchoring and is thereby lost.
Aufgabe der Erfindung ist es deshalb, eine Ultraschall-Schweißvorrichtung anzugeben, bei welcher der Werkstückhalter so konstruiert wird, dass eine Prozessoptimierung beim Ultraschweißprozess insbesondere von metallischen und polymerbasierten Komponenten hinsichtlich der Stabilität der Bindungsbildung, der Güte der Schweißverbindung, der mechanischen und elektrischen Zuverlässigkeit und Langzeitstabilität als auch des Verschleißes von Ultraschallwerkzeugen bewirkt wird. Insbesondere soll die erfindungsgemäße Ultraschall-Schweißvorrichtung beim Ultraschallschweißen von Folienflachleitern (FFC, FPC) in der Automobilindustrie einsetzbar sein.task The invention is therefore an ultrasonic welding device indicate where the workpiece holder is constructed so that a process optimization in the ultrasonic welding process in particular of metallic and polymer-based components with regard to the stability of bond formation, the goodness the welded connection, the mechanical and electrical reliability and long-term stability as well of wear of ultrasonic tools is effected. In particular, the ultrasonic welding device according to the invention in ultrasonic welding of film flat conductors (FFC, FPC) can be used in the automotive industry.
Erfindungsgemäß wird diese Aufgabe mittels einer Ultraschall-Schweißvorrichtung mit den im Anspruch 1 genannten Merkmalen gelöst.According to the invention this Task by means of an ultrasonic welding device with the in the claim 1 mentioned features solved.
Dadurch, dass der Werkstückhalter, insbesondere aufgrund seiner Geometrie und Massenverteilung, während des Schweißprozesses als mechanisches Schwingsystem wirkt, welches die Bindungsbildung an der Schweißstelle unterstützt, ist es vorteilhaft möglich, Ultraschallenergie, die ansonsten als Verlustleistung im Werkstückhalter in Wärmeenergie umgewandelt wird, in die Schweißstelle zurückzuführen, und so den Wirkungsgrad des Prozesses unmittelbar zu erhöhen. Die mittels Ultraschall in das Werkstück eingekoppelte mechanische Leistung wird ohne Modifikation der Schwingungsamplitude der Sonotrode erhöht.Thereby, that the workpiece holder, in particular due to its geometry and mass distribution, during the welding process acts as a mechanical vibration system, which the bond formation at the weld support it is advantageously possible Ultrasonic energy, otherwise as power dissipation in the workpiece holder converted into heat energy is, in the weld due, and thus immediately increasing the efficiency of the process. The by means of ultrasound coupled into the workpiece mechanical Performance is without modification of the vibration amplitude of the sonotrode elevated.
Durch die aktive Unterstützung der Bindungsbildung durch den Werkstückhalter ist
- – eine Verkürzung der Schweiß- und damit der gesamten Prozesszeit,
- – eine Reduzierung der Prozessparameter, insbesondere von Anpressdruck und Energie,
- – eine Erhöhung der Standzeit von Ultraschallwerkzeugen infolge geringerer Belastung und
- – eine Erhöhung der Prozesstoleranz bei kontaminierten und verschmutzten Werkstücken
- - a shortening of the welding and thus the entire process time,
- A reduction of the process parameters, in particular of contact pressure and energy,
- - An increase in the service life of ultrasonic tools due to lower load and
- - An increase in the process tolerance for contaminated and contaminated workpieces
Zwei Ausgestaltungen der Erfindung sind hierbei zu unterscheiden, wobei im Einzelfall in Abhängigkeit des herzustellenden Produktes zu entscheiden ist, welche der Ausgestaltungen vorzuziehen ist.Two Embodiments of the invention are to be distinguished here, wherein depending on individual case to decide the product to be produced, which of the embodiments is preferable.
Im ersten, speziellen Fall ist vorgesehen, dass das entstehende mechanische Schwingsystem eine Resonanzfrequenz aufweist, welche der Frequenz der Ultraschallschwingungen der Sonotrode im Wesentlichen entspricht. Dies bedeutet, dass bei geeigneter Wahl der Geometrie des Werkstückhalters dieser durch die Schwingungen der Sonotrode zu phasenverschobenen Resonanzschwingungen angeregt wird. Dies bietet sich besonders an, wenn große Amplituden der Relativbewegung an der Schweißstelle benötigt werden. Allerdings muss hier wegen einer etwaigen Resonanzüberhöhung eine vorsichtige Kontrolle des Schweißprozesses erfolgen.in the first, special case is provided that the resulting mechanical Oscillation system has a resonant frequency, which is the frequency the ultrasonic vibrations of the sonotrode substantially corresponds. This means that with a suitable choice of the geometry of the workpiece holder this phase-shifted by the vibrations of the sonotrode Resonant vibrations is excited. This is especially appropriate if big Amplitudes of relative movement at the weld are needed. However, must Here, because of any resonance overshoot a careful control of the welding process respectively.
Der zweite, allgemeinere Fall entspricht dem Nichtresonanzfall, in dem ebenfalls eine Verbesserung der Bindungsbildung erzielt wird, indem es zu einer Reflexion der in den Werkstückhalter induzierten Schwingungen und zu einer Konzentration der mechanischen Energie in der Spitze des Werkstückhalters nahe der Schweißstelle kommt. Dieser Effekt ist bei geeigneter Wahl der Geometrie des Werkstückhalters bei jeder Anregungsfrequenz vorhanden.Of the second, more general case corresponds to the non-resonant case in which also an improvement of bond formation is achieved by it is a reflection of the vibrations induced in the workpiece holder and to a concentration of mechanical energy in the top of the workpiece holder near the weld comes. This effect is with a suitable choice of the geometry of the workpiece holder present at every excitation frequency.
Insbesondere ist bevorzugt, dass der Werkstückhalter eine wulstartige Verdickung aufweist, welche als Reflektor für die von der Sonotrode erzeugten Ultraschallschwingungen wirkt.Especially it is preferred that the workpiece holder has a bead-like thickening, which serves as a reflector for the the sonotrode produces ultrasonic vibrations.
Der Werkstückhalter wird hierbei überwiegend schlank gestaltet, mit Ausnahme der wulstartigen Verdickung, welche eine vergrößerte Massenanhäufung in der Mitte des Werkstückhalter darstellt, an welcher die Ultraschallschwingungen reflektiert werden. Verschiedenste Ausführungen dieser Massenanhäufung sind denkbar, z. B. kugelförmig oder in der Form einer Scheibe.Of the Workpiece holder is here predominantly slender, with the exception of the bead-like thickening, which an increased mass accumulation in the middle of the workpiece holder represents, on which the ultrasonic vibrations are reflected. Different versions this mass accumulation are conceivable, for. B. spherical or in the form of a disc.
Die optimale Werkstückhalter-Form hängt stark von Werkstoff, Geometrie und Struktur der zu verbindenden Werkstücke ab. Dabei sind die Schwingeigenschaften der Werkstücke und der Sonotrode als konstant anzusehen, während die Eigenschaften des Werkstückhalters, insbesondere Material, Geometrie und Massenverteilung, und insbesondere die Massenverteilung entlang der Symmetrieachse im Falle einer zylindersymmetrischen Ausgestaltung des Werkstückhalters, als Variablen eines Optimierungsproblems behandelt werden.The optimal workpiece holder shape depends strongly of material, geometry and structure of the workpieces to be joined. The swinging properties of the workpieces and the sonotrode are constant to look at while the properties of the workpiece holder, in particular material, geometry and mass distribution, and in particular the mass distribution along the axis of symmetry in the case of a cylindrically symmetric Embodiment of the workpiece holder, treated as variables of an optimization problem.
Grundsätzlich ist es vorteilhaft, dass der Werkstückhalter im Wesentlichen aus homogenem Material angefertigt ist. Dadurch werden ungewünschte und schwer kontrollierbare Reflexionen an Materialgrenzflächen unterdrückt. Andererseits ist zumindest eine Ausführung vorgesehen, in welcher der Werkstückhalter einen Massenring aufweist, welcher axial verschiebbar ist, durch welchen eine Feinanpassung der Frequenz erfolgen kann, mit welcher der Werkstückhalter schwingt.Basically It is advantageous that the workpiece holder essentially made of homogeneous material. Thereby will be unwanted and difficult to control reflections at material interfaces suppressed. on the other hand is at least one execution provided in which the workpiece holder has a mass ring, which is axially displaceable, through which a fine adjustment the frequency can be done with which the workpiece holder swings.
Weiter ist bevorzugt, dass das mechanische Schwingsystem durch die Schwingungen der Sonotrode zu elliptischen Schwingungen anregbar ist. Im Werkstückhalter ergibt sich also eine überlagerte Schwingung mit vertikalen und horizontalen Anteilen. Um dies zu erreichen, müssen zumindest kleine Abweichungen in der Symmetrie bei der Konstruktion des Werkstückhalters vorgesehen sein. Durch die elliptischen Schwingungen kann ein Transport von Fremdpartikeln aus der Bindungszone induziert werden. Dies ist besonders beim Schweißen von stark verschmutzten Werkstoffen erwünscht.Further it is preferred that the mechanical vibration system by the vibrations the sonotrode is excitable to elliptical vibrations. In the workpiece holder So there is a superimposed oscillation with vertical and horizontal proportions. To achieve this, have to at least small deviations in the symmetry in the construction of the Workpiece holder be provided. Due to the elliptical vibrations can be a transport be induced by foreign particles from the binding zone. This is especially when welding desired from heavily contaminated materials.
Das erfindungsgemäße Verfahren zum Design eines geeigneten Werkstückhalters ist dadurch gekennzeichnet, dass die Geometrie des Werkstückhalters mathematisch und/oder messtechnisch optimiert wird, damit der Werkstückhalter während des Schweißprozesses in einer Form schwingt, welche die Bindungsbildung während der Schweißung aktiv unterstützt.The inventive method for the design of a suitable workpiece holder is characterized that the geometry of the workpiece holder is mathematically and / or metrologically optimized so that the workpiece holder while of the welding process vibrates in a form that enhances bond formation during the process welding actively supported.
Dabei ist bevorzugt, die optimale Form des Werkstückhalters in einem iterativen Prozess aus ingenieurwissenschaftlich mathematischen Verfahren, insbesondere durch Anwendung einer Finite-Elemente-Methode oder einer elektromechanischen Analogie, und schwingungstechnischer Analyse, insbesondere durch Laserinterferometrie, zu ermitteln. Insbesondere ist hierbei die Ankopplung und mechanische Fixierung des Werkstückhalters im Restsystem des Schweißautomaten mit entsprechenden Dämpfungs- und Federelementen zu berücksichtigen.there is preferred, the optimal shape of the workpiece holder in an iterative Process of engineering mathematical methods, in particular by applying a finite element method or an electromechanical analogy, and vibration analysis, in particular by laser interferometry, to investigate. In particular, in this case the coupling and mechanical Fixation of the workpiece holder in the remainder of the welding machine with corresponding damping and spring elements to be considered.
Weitere bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den übrigen, in den Unteransprüchen genannten Merkmalen.Further preferred embodiments of the invention will become apparent from the others, in the subclaims mentioned features.
