- FFCs are increasingly used today in industry and in particular in the automotive industry over round cables, since they can be processed by machines.
- they make it possible to create electrically conductive connections in the form of branching points by the insulating material is removed around the conductors to be contacted, the two FFCs are placed one above the other, the interconnected interconnects to each other and the junction then with a potting material or insulating tapes or the like is re-isolated.

- the present application relates to the arrangement of at least two lasers, between which there is an FFC in which a window is to be created. Placing two aligned and frontally aligned lasers in the fabrication of windows in FFCs is given because of the small size of the windows and the need to create the windows from both sides. If one moves the machining between stripping the upper side and stripping the underside of the FFC, one achieves the required accuracy of positioning only with disproportionate effort and that only in small clock rates. There is the unfavorable possibility that by moving the FFC from the stripping on the top for stripping on the bottom of a window or vice versa it comes to an offset.

- the two lasers 3, 4, which are shown purely schematically in FIG. 1 and not according to their actual arrangement, are arranged coaxially along an axis 7 and directed against each other. In most applications, the lasers are located some distance from the object, and the laser beams are focused and focussed on their target by means of an optic (which may also include flexible light guides).
- the structures denoted by 3 and 4 thus correspond most closely to the optics, which of course also belongs to the laser in a broader sense.
- the lasers 3, 4 are simultaneously movable in the area of the window 2 to be formed in order to create the window of the desired size and shape.

- the switches 23, 24 need not directly activate the lasers 3, 4, but give corresponding signals to the actual control electronics for the two lasers. In any case, it is ensured by the provision of the device 8 that the two lasers 3, 4 can not damage each other.
- a modified construction 18 is shown in Fig. 2, which is based on a reciprocal linear movement of two cover plates 13 '14'.
- the guide of the purely schematic section of Figure 2 is normal to the schematic section of Fig. 1, so that it can be seen in this illustration that the FFC 1 has a plurality of conductor tracks 5 and how they are arranged to each other.
- the operation of the safety device 18 is based on the pivoting of a pivot lever 10, for example by a (not shown) connecting rod of a motor or by an electromagnet which acts directly on a corresponding ferromagnetic part of the cover 13 '14' or by a pneumatic drive, and assures again that at least one of the discs is in front of their assigned laser.

Abstract
Description
Die Erfindung betrifft ein Verfahren bzw. eine Vorrichtung zur Abisolierung von flachen, flexiblen Leitern entsprechend dem einleitenden Teil der Ansprüche 1 bzw. 3.The invention relates to a method and a device for stripping flat, flexible conductors according to the introductory part of
Ein Verfahren bzw. eine Vorrichtung zum Aufbringen von Leiterbahnen auf Leiterplatten, die Laser verwendet, ist aus der US 4,818,322 A bekannt.A method and apparatus for applying printed circuit traces to printed circuit boards using lasers is known from US 4,818,322 A.
FFCs werden heute in der Industrie und insbesondere im Automobilbau zunehmend gegenüber Rundkabeln verwendet, da sie durch Automaten verarbeitet werden können. Darüber hinaus erlauben sie es, elektrisch leitende Verbindungen in Form von Abzweigstellen zu schaffen, indem rund um die zu kontaktierenden Leiterbahnen das Isolationsmaterial entfernt wird, die beiden FFCs passend übereinander gelegt werden, die zu verbindenden Leiterbahnen miteinander verbunden werden und die Verbindungsstelle sodann mit einem Vergußmaterial oder isolierenden Klebebändern oder dergleichen wieder isoliert wird. Darüber hinaus ist es notwendig, im Endbereich eines jeden FFCs derartige Fenster anzubringen, um Stecker, Buchsen, Kontakte oder dergleichen anbringen zu können.FFCs are increasingly used today in industry and in particular in the automotive industry over round cables, since they can be processed by machines. In addition, they make it possible to create electrically conductive connections in the form of branching points by the insulating material is removed around the conductors to be contacted, the two FFCs are placed one above the other, the interconnected interconnects to each other and the junction then with a potting material or insulating tapes or the like is re-isolated. Moreover, it is necessary to install such windows in the end region of each FFC in order to mount plugs, sockets, contacts or the like.
Die Schaffung derartiger Fenster erfolgt im Stand der Technik durch eine Kombination eines Stanzvorganges mit einem Schälvorgang bzw. einer spanenden Bearbeitung und ist aufwendig und wegen der anfallenden Extrudatpartikel unangenehm. Es wurde bereits versucht, die Fenster mittels Lasers herzustellen, doch führt dies zu einer Beeinträchtigung der Oberfläche der Leiterbahnen, die daraufhin chemisch behandelt werden muß, bevor die Weiterverarbeitung möglich ist. Die notwendige chemische Behandlung macht es im Fabrikationsprozeß notwendig, eine Arbeitsstation vorzusehen, bei der mit entsprechenden flüssigen Chemikalien hantiert wird, die über entsprechende Absaugungen und Abflüsse verfügt und der ein Trocknungs- und Kontrollschritt nachfolgen muß, um sicher zu stellen, dass die erhaltenen FFCs einwandfrei sind. Eine derartige Station ist ein Fremdkörper in einer ansonsten elektronisch, mit Lasern und dergleichen arbeitenden Fertigungsstraße und daher tunlichst zu vermeiden.The creation of such windows takes place in the prior art by a combination of a punching process with a peeling process or a machining operation and is complicated and unpleasant because of the resulting extrudate. It has already been attempted to produce the windows by means of laser, but this leads to an impairment of the surface of the tracks, which then has to be chemically treated before further processing is possible. The necessary chemical treatment makes it necessary in the fabrication process to provide a work station where appropriate liquid chemicals are handled, which have appropriate suction and drains, and which must be followed by a drying and control step to ensure that the FFCs obtained are flawless are. Such a station is a foreign body in an otherwise electronic, working with lasers and the like production line and therefore avoid as far as possible.
Es wurde von der Anmelderin ein auf Lasertechnik basierendes Verfahren entwickelt, dass die genannten Probleme beseitigt und zu technologisch einwandfreien Fenstern im FFC führt. Dieses Verfahren wird getrennt von der vorliegenden Arimeldung zum Patent angemeldet. Die vorliegende Anmeldung betrifft die Anordnung zumindest zweier Laser, zwischen denen sich ein FFC befindet, in dem ein Fenster geschaffen werden soll. Das Anordnen zweier, fluchtend zueinander und frontal aufeinander orientierter Laser bei der Herstellung von Fenstern in FFCs ist wegen der Kleinheit der Fenster und der Notwendigkeit, die Fenster von beiden Seiten her zu schaffen, gegeben. Wenn man bei der Bearbeitung zwischen Abisolieren der Oberseite und mit dem Abisolieren der Unterseite den FFC bewegt, erreicht man die benötigte Genauigkeit der Positionierung nur mit unverhältnismäßig großem Aufwand und auch das nur in kleinen Taktraten. Es besteht die ungünstige Möglichkeit, dass durch die Bewegung der FFC von der Abisolierung auf der Oberseite zur Abisolierung auf der Unterseite eines Fensters oder umgekebrt es zu einem Versatz kommt.The applicant has developed a laser-based method that eliminates the above problems and leads to technologically sound windows in the FFC. This process is patent pending separately from the present application. The present application relates to the arrangement of at least two lasers, between which there is an FFC in which a window is to be created. Placing two aligned and frontally aligned lasers in the fabrication of windows in FFCs is given because of the small size of the windows and the need to create the windows from both sides. If one moves the machining between stripping the upper side and stripping the underside of the FFC, one achieves the required accuracy of positioning only with disproportionate effort and that only in small clock rates. There is the unfavorable possibility that by moving the FFC from the stripping on the top for stripping on the bottom of a window or vice versa it comes to an offset.
Dabei hat sich herausgestellt, dass trotz aller Sorgfalt bei der eingesetzten Steuer- und Regeltechnik ein Restrisiko besteht, dass einer der beiden Laser aktiviert wird, wenn sich im FFC bereits ein Fenster befindet, (oder, aus welchen Gründen auch immer, gar kein FFC eingeschoben ist) wodurch er direkt in den anderen, inaktiven Laser strahlt und dort Beschädigungen hervorruft.It has been found that, despite all the care taken in the control and regulation technology used, there is a residual risk that one of the two lasers will be activated if there is already a window in the FFC (or, for whatever reason, no FFC inserted at all) whereby it radiates directly into the other, inactive laser and causes damage there.
Es ist die Aufgabe der Erfindung, dieses Problem kostengünstig und zuverläßig zu lösen.It is the object of the invention to solve this problem inexpensively and reliably.
Erfindungsgemäß wird dieses Problem zuverlässig und kostengünstig durch die Merkmale des kennzeichnenden Teiles der Ansprüche 1 und 3 vermieden.According to the invention, this problem is reliably and inexpensively avoided by the features of the characterizing part of
Auf diese Weise ist sichergestellt, dass vor dem nicht aktivierten Laser stets eine Abdeckung angeordnet ist, die das Eindringen des Laserstrahls des anderen Lasers auch dann zuverlässig verhindert, wenn sich beispielsweise kein FFC zwischen den Lasern befindet oder ein FFC mit bereits vollständig ausgebildetem Fenster.In this way it is ensured that a cover is always arranged in front of the non-activated laser, which reliably prevents the penetration of the laser beam of the other laser even if, for example, there is no FFC between the lasers or an FFC with an already fully formed window.
In einer bevorzugten Ausgestaltung besteht die Abdeckung jedes Lasers aus einer sich drehenden Scheibe mit entsprechenden Löchern oder Ausnehmungen, wobei bevorzugt die beiden Scheiben für die beiden Laser auf einer gemeinsamen Drehachse montiert sind.In a preferred embodiment, the cover of each laser consists of a rotating disc with corresponding holes or recesses, wherein preferably the two discs for the two lasers are mounted on a common axis of rotation.
Die Erfindung wird im Folgenden anhand der Zeichnung näher erläutert. Dabei zeigt die
- Fig. 1 eine Ausführungsform der Erfindung mit Drehscheiben und die
- Fig. 2 eine Ausführungsform mit hin-/hergehenden Abdeckungen.
- Fig. 1 shows an embodiment of the invention with turntables and the
- Fig. 2 shows an embodiment with reciprocating covers.
Die Fig. 1 zeigt, rein schematisch, eine erfindungsgernäße Anordnung. Durch eine derartige Bearbeitungsstation wird ein FFC 1 durch geleitet und an den Stellen, an denen ein Fenster 2 hergestellt werden soll, im Bereich zwischen 2 Lasern 3, 4 angehalten und passend positioniert und fixiert, um das Fenster 2 mit der notwendigen geometrischen Genauigkeit herstellen zu können.Fig. 1 shows, purely schematically, a erfindungsgernäße arrangement. By such a processing station FFC 1 is passed through and at the points where a
Der FFC 1 besteht aus mehreren zueinander parallel in einer Ebene verlaufenden Leiterbahnen 5, von denen zufolge der Führung des Schnittes in der Fig. 1 nur eine sichtbar ist, und dem die Leiterbahnen umgebenden Extrudat 6 aus elektrisch isolierendem, aber in Grenzen plastisch deformierbaren Material.The FFC 1 consists of several parallel to each other in a
Die beiden Laser 3, 4, die in Fig. 1 rein schematisch und nicht entsprechend ihrer wirklichen Anordnung dargestellt sind, sind koaxial entlang einer Achse 7 angeordnet und gegeneinander gerichtet. In den meisten Anwendungsfällen sind die Laser in einigem Abstand vom Objekt angeordnet und die Laserstrahlen werden mittels jeweils einer Optik (die auch flexible Lichtleiter umfassen kann) auf ihr Ziel gerichtet und passend fokussiert. Die mit 3 bzw. 4 bezeichneten Gebilde entsprechen somit am ehesten der Optik, die aber selbstverständlich ebenfalls zum Laser im weiteren Sinn gehört. Die Laser 3, 4 sind im Bereich des zu bildenden Fensters 2 simultan beweglich, um das Fenster mit der gewünschten Größe und Form zu schaffen.The two
Wie aus Figur 1 leicht ersichtlich ist, besteht die Gefahr, dass einer der Laser 3, 4 aktiviert wird, obwohl sich keine FFC 1 zwischen ihnen befindet oder obwohl bereits ein Fenster 2 besteht und sich kein Extrudat mehr zwischen den Lasern befindet und diese auf einem Bereich gerichtet sind, in dem sich keine Leiterbahn 5 befindet. Da die Fenster 2 eine größere Fläche aufweisen, als es der Grundfläche der Leiterbahnen 5 entspricht, besteht diese Möglichkeit auch im normalen Betrieb. Da die beiden Laser und ihre Optik völlig symmetrisch aufgebaut sein müssen, kann es in diesem Fall der Aktivierung unweigerlich zu einer Beschädigung oder Zerstörung des jeweils inaktiven Lasers kommen.As is readily apparent from Figure 1, there is a risk that one of the
Um dies zu verhindern, ist erfindungsgemäß eine in ihrer Gesamtheit mit 8 bezeichnete Unterbrechungsvorrichtung in unmittelbarer Nachbarschaft zum FFC 1 und den Lasern 3, 4 angeordnet. Diese besteht im wesentlichen aus einer durch einen (nicht dargestellten) Motor in Drehung versetzten Welle 9, die zwei Abdeckscheiben 13, 14 trägt, die jeweils einem der Laser 3, 4 zugeordnet sind. Die Rotorwelle 9 steht im wesentlichen normal auf die Ebene des FFC 1 und ist relativ knapp neben dem Rand des FFC 1 angeordnet. Auf diese Weise befinden sich in Abhängigkeit von der Winkellage der Rotorwelle 9 und somit der Abdeckscheiben 13, 14 Abschnitte dieser Scheiben vor dem zugeordneten Laser 3,4 oder nicht.In order to prevent this, according to the invention, an interruption device designated in its entirety by 8 is arranged in the immediate vicinity of the FFC 1 and the
Die Fig. 1 zeigt jene Winkellage, in der sich die Abdeckscheibe 13 vor dem Laser 3 befindet, während die Abdeckscheibe 14 den Laser 4 frei gibt, so dass dieser aktiviert werden kann. Diese wechselweise Aktivierung wird bevorzugt mittels einer Schaltung vorgenommen, die von der Winkellage der Drehachse 9 und damit der Winkellage die Abdeckscheiben 13, 14 abgeleitet wird. In Fig. 1 ist dies schematisch am unteren Ende der Rotorwelle 9 dargestellt, wo ein Schalter 23 für den Laser 3 und ein Schalter 24 für den Laser 4 angedeutet ist.Fig. 1 shows that angular position in which the
Selbstverständlich ist es möglich, statt der exzentrischen Abdeckscheiben 13, 14 zahnradähnliche Gebilde vorzusehen und so bei den angestrebten hohen Drehzahlen zu einer dynamisch ausgewuchteten Situation zu kommen. Gleichermaßen ist es möglich, statt einer zahnradartigen Konstruktion Lochscheiben vorzusehen, durch die der gleiche Zweck erfüllt wird. Die Schalter 23, 24 müssen selbstverständlich nicht direkt die Laser 3, 4 aktivieren, sondern geben entsprechende Signale an die eigentliche Steuerelektronik für die beiden Laser. Jedenfalls aber wird durch das Vorsehen der Vorrichtung 8 sichergestellt, dass die beiden Laser 3, 4 einander nicht beschädigen können.Of course, it is possible, instead of the
Auf analoge Weise ist in Fig. 2 eine abgewandelte Konstruktion 18 dargestellt, die auf einer reziproken linearen Bewegung zweier Abdeckscheiben 13' 14' beruht. Die Führung des rein schematischen Schnittes der Figur 2 liegt normal zum schematischen Schnitt der Fig. 1, so dass in dieser Darstellung ersichtlich ist, dass der FFC 1 mehrere Leiterbahnen 5 aufweist und wie diese zueinander angeordnet sind. Die Funktionsweise der Sicherheitsvorrichtung 18 beruht auf dem Verschwenken eines Schwenkhebels 10, beispielsweise durch ein (nicht dargestelltes) Pleuel eines Motors oder durch einen Elektromagneten, der direkt auf einen entsprechend ferromagnetischem Teil der Abdeckscheiben 13' 14' einwirkt oder auch durch einen pneumatischen Antrieb, und sichert auch hier wieder, dass sich zumindest eine der Scheiben vor dem ihr zugeordneten Laser befindet. Durch die entsprechend angeordneten Schalter 23, 24 erfolgt wieder die steuerungstechnische Freigabe des jeweils nicht abgedeckten Lasers zur Schaffung der gewünschten Fenster 2 im FFC 1.In an analogous manner, a modified
Es sind selbstverständlich noch andere Ausführungen möglich, beispielsweise solche, bei denen für jeden der beiden Laser mehrere Abdeckungen vorgesehen sind, was zwar die Vorrichtung größer und komplexer werden läßt, dafür aber erlaubt, die Geschwindigkeit der beweglichen Teile zu verringern, doch ist insbesondere die Ausbildung gemäß Fig.1 vorteilhaft und bevorzugt.Of course, other embodiments are possible, for example, those in which several covers are provided for each of the two lasers, which, although the device can be larger and more complex, but allows the speed reduce the moving parts, but in particular the embodiment according to Figure 1 is advantageous and preferred.
Es sind in Kenntnis der Erfindung bzw. ihres Grundgedankens auch zahlreiche Abwandlungen der Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens möglich, die auf anderen Bewegungen beruhen:With knowledge of the invention or its basic idea, numerous modifications of the device for carrying out the method according to the invention are possible, which are based on other movements:
So können die beiden Abdeckungen (Verfielfachungen werden nicht mehr extra erwähnt) auf einem gemeinsamen Schlitten sitzen, der eine reziproke Bewegung vollführt, die elektrisch, pneumatisch oder auch hydraulisch bewirkt werden kann, wobei immer eine der Abdeckungen in den Bereich der ihr zugeordneten Laserquelle kommt und die andere aus diesem Bereich entfernt ist.Thus, the two covers (Verbielfachungen are no longer mentioned separately) sitting on a common carriage, which performs a reciprocal movement, which can be effected electrically, pneumatically or hydraulically, with one of the covers always comes in the area of its associated laser source and the other is removed from this area.
Es können auch die beiden Abdeckungen am Mantel einer Trommel angeordnet sein, in der der FFC entlang der Trommelachse verläuft, wobei sich die Trommel um iher Achse dreht. In diesem Fall könnte die Trommel auch zum Absaugen der unangenehmen, beim Abtragen des Extrudates entstehenden Dämpfe und Gase verwendet werden.The two covers may also be disposed on the shell of a drum in which the FFC runs along the drum axis, with the drum rotating about its axis. In this case, the drum could also be used to extract the unpleasant vapors and gases produced during the removal of the extrudate.
