Abstract

Ce dispositif permet de parer aux inconvénients inhérents à l'équipement des cartes de circuits imprimés (13) avec des éléments électroniques (12) à fils. Ces inconvénients sont les suivants: difficulté de positionnement des outils de travail par le bas par rapport à un orifice (11) destiné au passage de fils de connection à travers la carte de circuits imprimés (13); manque de support pour les composants (12) entre les opérations d'équipement et de soudure; et enfin fréquence des courts-circuits dus à des fils (14) gauchis sur la face inférieure des cartes de circuits imprimés (13). Les deux mâchoires de sectionnement et de pliage (1, 2) de l'outil proposé coopèrent pour réaliser l'opération de coupure et de pliage, où le fil de connection (14) est coupé à longueur et replié, de telle manière qu'aucune force d'importance ne s'exerce sur la carte de circuits imprimés (13). Un élément supérieur rajouté (5) permet de régler de manière précise la longueur du fil de connection (14). L'effet d'entaille produit par des dents de serrage (10) facilite l'opération de pliage et rend les composants plus faciles à souder.This device overcomes the drawbacks inherent in equipping printed circuit boards (13) with electronic elements (12) with wires. These drawbacks are as follows: difficulty in positioning the working tools from below relative to an orifice (11) intended for the passage of connection wires through the printed circuit board (13); lack of support for components (12) between equipment and welding operations; and finally the frequency of short circuits due to warped wires (14) on the underside of printed circuit boards (13). The two sectioning and folding jaws (1, 2) of the proposed tool cooperate to carry out the cutting and folding operation, where the connecting wire (14) is cut to length and folded back, so that no significant force is exerted on the printed circuit board (13). An added upper element (5) makes it possible to precisely adjust the length of the connection wire (14). The notch effect produced by clamping teeth (10) facilitates the folding operation and makes the components easier to weld.

Description

Vorrichtung zum Ablängen und Biegen von AnschlußdrähtenDevice for cutting and bending connecting wires

Die Erfindung betrifft eine Vorrichtung zum Ablängen und Biegen von AnschluBdrähten von elektronischen Bauteilen bei deren Mon¬ tage auf Leiterplatten mittels Unterwerkzeuge.The invention relates to a device for cutting and bending connecting wires of electronic components during their assembly on printed circuit boards by means of lower tools.

Bei der Bestückung von Leiterplatten mit bedrahteten Bauteilen müssen deren Anschlußdrähte auf der Unterseite der Leiterplatte definiert abgelängt werden. Ein anschließendes Umbiegen sorgt dafür, daß bis zum Einlöten des Bauteils ein sicherer Halt ge¬ währleistet ist. Bei diesem Biegevorgang soll jedoch durch den Anschlußdraht kein Kurzschluß an benachbarten auf derWhen assembling printed circuit boards with wired components, their connecting wires must be cut to length on the underside of the printed circuit board. Subsequent bending ensures that a secure hold is ensured until the component is soldered in. In this bending process, however, no short circuit to adjacent ones on the

Unterseite der Leiterplatte liegenden Leiterbahnen entstehen. Für das Ablängen und Umbiegen werden in der Regel sogenannte Unterwerkzeuge eingesetzt, die aus Schneidbacken und Biegebacken bestehen.Undersides of the printed circuit board are created. So-called lower tools, which consist of cutting jaws and bending jaws, are generally used for cutting and bending.

Bei bekannten Unterwerkzeugen werden die Anschlußdrähte nach dem Schneidvorgang beim Ablängen von einem Biegebacken gegen die Leiterplattenbohrung gedrückt und somit umgebogen. Das hat zur Folge, daß durch relativ kleine Positionsungenauigkeiten zwischen der Bohrung der Leiterplatte und der Biegebacke schlechte Biegeergebnisse erzielt werden, Leiterbahnen be¬ schädigt werden, Kurzschlüsse entstehen oder die elektronischen Bauteile teilweise aus der Leiterplatte herausfallen können.In the case of known lower tools, the connecting wires are pressed against the printed circuit board bore after the cutting process and cut to length from a bending jaw, and are thus bent over. The consequence of this is that, due to relatively small position inaccuracies between the hole in the circuit board and the bending jaw, poor bending results are achieved, conductor tracks are damaged, short circuits occur or the electronic components can fall out of the circuit board.

Der Erfindung liegt die Aufgabe zugrunde, ein Unterwerkzeug zur Verfügung zu stellen, das ein definiertes Ablängen und ein feh¬ lerfreies Biegen von Anschlußdrähten elektronischer Bauteile bei deren Montage auf Leiterplatten ermöglicht, wobei eine sichere Halterung der Bauteile bis zum Einlöten gewährleistet ist und keinerlei Kurzschlüsse entstehen.The invention is based on the object of providing a lower tool which enables a defined cutting to length and an error-free bending of connecting wires of electronic components when they are mounted on printed circuit boards, a secure mounting of the components being guaranteed until soldering in and no short circuits occurring .

Die Lösung dieser Aufgabe wird durch den Einsatz einer Vorrich¬ tung erbracht, bei der ein erster Schneid-Biegebacken mit einer Schneidkante und mindestens einem Greifzacken und ein zweiter Schneid-Biegebacken mit einem Aufbau, einer Biegekante, einer Kante und einer Fläche vorhanden sind, wobei die Schneidkante mit der Kante zusammenwirkt, die Greifzacken mit der Fläche zusammenwirken, der Anschlußdraht um die Biegekante gebogen wird und in einem Arbeitsgang ein Anschlußdraht abgelängt und umgebogen werden kann.This object is achieved by using a device in which a first cutting and bending jaw with a Cutting edge and at least one gripping prong and a second cutting bending jaw with a structure, a bending edge, an edge and a surface are present, the cutting edge interacting with the edge, the gripping prongs interacting with the surface, the connecting wire being bent around the bending edge and in a connecting wire can be cut to length and bent in one operation.

Der Erfindung liegt die Erkenntis zugrunde, daß durch zwei gegeneinander wirkende Schneid-Biegebacken ein exaktes Ablängen und ein definiertes Umbiegen von Anschlußdrähten möglich ist, ohne daß eine Kraft auf die Leiterplatte bzw. die darin vor¬ handene Bohrung ausgeübt wird. Hierdurch wird ein ausschließlich'1 zwischen den beiden Schneid-Biegebacken ablau- fender Abläng- und Biegevorgang ermöglicht, wobei ein vorbe¬ stimmter Abbiegewinkel durch die Ausgestaltung der Fläche einer Schneid-Biegebacke erzielbar ist. Die Positionierung zwischen UnterWerkzeug und Bohrung erfolgt in relativ großen Toleranzbereichen.The invention is based on the finding that exact cutting to length and a defined bending of connecting wires is possible by means of two counter-bending jaws acting against one another without any force being exerted on the printed circuit board or the bore therein. This produces a solely '1 between the two cutting-bending jaws flow-off allows fender cutting and bending operation, wherein a vorbe¬ certain turning angle is a cutting-bending jaw achievable by the configuration of the surface. The positioning between the lower tool and the bore takes place in relatively large tolerance ranges.

In einer weiteren Ausgestaltung der Erfindung wird durch einen Aufbau einer Schneid-Biegebacke, auf den die Leiterplatte aufgelegt ist, ein vorbestimmter Abstand zwischen der Unterseite der l* iterplatte und der Schnittstelle, an der der Anschlußdraht abgelängt wird, eingestellt.In a further embodiment of the invention, a predetermined distance between the underside of the circuit board and the interface at which the connecting wire is cut to length is set by the construction of a cutting and bending jaw on which the printed circuit board is placed.

Durch einen für den Schneid-Biegevorgang gemeinsamen Drehpunkt für beide Schneid-Biegebacken wird die Konstruktion der erfindungsgemäßen Vorrichtung vereinfacht.The construction of the device according to the invention is simplified by a pivot point common to the cutting-bending process for both cutting-bending jaws.

Zur gezielten Einstellung der Biegerichtung der Anschlußdrähte ist das Unterwerkzeug drehbar gelagert.The lower tool is rotatably mounted for targeted adjustment of the bending direction of the connecting wires.

Im folgenden wird anhand der schematischen Figuren ein Ausfüh- rungsbeispiel beschrieben.An exemplary embodiment is described below with reference to the schematic figures.

Figur 1 zeigt eine Vorrichtung mit Leiterplatte und Bauelement in der Ausgangsstellung. Figur 2 zeigt eine Vorrichtung entsprechend Figur 1 in der Ar¬ beitsstellung.Figure 1 shows a device with circuit board and component in the starting position. FIG. 2 shows a device corresponding to FIG. 1 in the working position.

Figur 3 zeigt eine Vorrichtung in der Endstellung.Figure 3 shows a device in the end position.

In der Figur 1 ist ein erster Schneid-Biegebacken 1 und ein zweiter Schneid-Biegebacken 2 zusammen mit einer Leiterplatte 13 und einem elektronischen Bauteil 12 sowie einem zugehörigen Anschlußdraht 14 dargestellt. Die Leiterplatte 13, die in der Regel aus Kunststoff hergestellt ist, weist die Bohrung 11 auf. Die Anschläge 9 sorgen für eine definierte Endstellung der beiden Schneid-Biegebacken 1, 2. Der erste Schneid-Biegebacken 1 weist eine Schneidkante 3 auf, die mit der Kante 4 des zweiten Schneid-Biegebackens 2 für den Schneidvorgang zusammenwirkt. Für den folgenden Biegevorgang wirkt die Biegekante 6 mit den Greifzacken 10 zusammen, wobei der Anschlußdraht 14 soweit gebogen wird, bis er an der Fläche 7 anliegt. Durch die Anstellung der Fläche 7 ist der Abbiegewinkel bestimmt. Der gemeinsame Drehpunkt 8 der beiden Schneid-Biegebacken 1, 2 ist in der Zeichnung angedeutet.1 shows a first cutting-bending jaw 1 and a second cutting-bending jaw 2 together with a printed circuit board 13 and an electronic component 12 and an associated connecting wire 14. The circuit board 13, which is usually made of plastic, has the bore 11. The stops 9 ensure a defined end position of the two cutting and bending jaws 1, 2. The first cutting and bending jaws 1 has a cutting edge 3 which interacts with the edge 4 of the second cutting and bending jaw 2 for the cutting process. For the following bending process, the bending edge 6 interacts with the gripping prongs 10, the connecting wire 14 being bent until it rests on the surface 7. The turning angle is determined by the inclination of the surface 7. The common pivot point 8 of the two cutting and bending jaws 1, 2 is indicated in the drawing.

Die Figur 2 zeigt die Vorrichtung in Arbeitsstellung, wobei der zweite Schneid-Biegebacken 2 bereits bis zum Anschlag 9 geführt wurde. Somit ist durch den Aufbau 5 der Abstand X zwischen der Schnittstelle, festgelegt durch die Schneidkante 3 und die Kante 4, und der Unterseite der Leiterplatte 13 eingestellt. Hierbei liegt die Leiterplatte 13 auf dem Schneid-Biegebacken 2 auf. Der erste Schneid-Biegebacken 1 bewegt sich in der darge¬ stellten Momentaufnahme noch auf den Anschlag 9 zu.FIG. 2 shows the device in the working position, the second cutting-bending jaw 2 having already been guided up to the stop 9. The spacing X between the interface, defined by the cutting edge 3 and the edge 4, and the underside of the printed circuit board 13 is thus set by the structure 5. Here, the circuit board 13 rests on the cutting and bending jaws 2. The first cutting-bending jaw 1 is still moving towards the stop 9 in the snapshot shown.

Um eine mögliche Beschädigung der Leiterplatte 13 durch die Be¬ wegung des Schneid-Biegebackens 2 zu verhindern, kann ein fest¬ stehender Anschlag für die Leiterplatte 13 so am Unterwerkzeug angebracht werden, daß sich die Biegekante 6 des Schneid-Biege- backens 2 mit einem definierten Abstand von z.B. 0,1 mm unter der Leiterplatte bewegen kann. In der Figur 3 sind der Schneid- und der Biegevorgang beendet. Der Anschlußdraht 14 ist auf Länge geschnitten, liegt an der Fläche 7 an und ist um die Biegekante 6 herumgebogen. In diesem Zustand liegt auch der erste Schneid-Biegebacken 1 am Anschlag 9 an. In Abhängigkeit vom Durchmesser der verarbeiteten Anschlußdrähte 14 wird durch den ersten Schneid-Biegebacken 1 mittels der Greifzacken 10 eine mehr oder weniger starke Einkerbung im Anschlußdraht 14 erzielt. Durch diese Kerbwirkung wird erreicht, daß beim Biegevorgang der Draht formschlüssig erfaßt wird und definiert um die Biege¬ kante 6 des zweiten Schneid-Biegebackens 2 gebogen wird. Ein Abgleiten des Anschlußdrahtes 14 nach oben ist dadurch selbst bei geringen Bauteile-Haltekräften wie z.B. bei der Handbe¬ stückung ausgeschlossen. Ein weiterer Vorteil dieser Einker- bung durch die Greifzacken 10 ergibt sich bei der weiteren Ver¬ arbeitung bei einem anschließenden Lötverfahren. Durch das Aufreißen von Oxidschichten, die auf dem Anschlußdraht 14 vor¬ handen sein können wird die Lötbarkeit erhöht. Durch den Einsatz der Greifzacken wird es ermöglicht, Anschlußdrähte 14 mit unterschiedlichen Durchmessern zu verarbeiten. Bei relativ kleinen Backenkräften können Drahtdurchmesser von beispiels¬ weise 0,3 bis 1 mm verarbeitet werden, wobei runde und recht¬ eckige Querschnitte möglich sind. Mit einer erfindungsgemäßen Vorrichtung ist bezüglich der Positionierung der Leiterplatte 13 und den darin enthaltenen Bohrungen 11 in Bezug aufIn order to prevent possible damage to the circuit board 13 by the movement of the cutting and bending jaw 2, a fixed stop for the circuit board 13 can be attached to the lower tool in such a way that the bending edge 6 of the cutting and bending jaw 2 is in contact with one another defined distance of 0.1 mm below the circuit board. In FIG. 3, the cutting and bending processes have ended. The connecting wire 14 is cut to length, lies against the surface 7 and is bent around the bending edge 6. In this state, the first cutting and bending jaw 1 also abuts the stop 9. Depending on the diameter of the processed connecting wires 14, a more or less strong notch in the connecting wire 14 is achieved by the first cutting-bending jaw 1 by means of the gripping prongs 10. This notch effect ensures that the wire is positively gripped during the bending process and is bent in a defined manner around the bending edge 6 of the second cutting and bending jaw 2. A sliding of the connecting wire 14 upwards is thereby ruled out, even with low component holding forces, such as in the case of manual assembly. Another advantage of this indentation by the gripping prongs 10 results in the further processing in a subsequent soldering process. The solderability is increased by tearing open oxide layers that may be present on the connecting wire 14. The use of the gripping prongs makes it possible to process connecting wires 14 with different diameters. With relatively small jaw forces, wire diameters of, for example, 0.3 to 1 mm can be processed, round and rectangular cross sections being possible. With a device according to the invention, with regard to the positioning of the printed circuit board 13 and the bores 11 contained therein, with respect to FIG

Schneid-Biegebacken nur ein geringer Aufwand nötig. Positions- ungenauigkeiten von ca. + 0,5 mm beeinflussen das Biegeer¬ gebnis nicht nachteilig.Cutting and bending jaws require little effort. Position inaccuracies of approximately + 0.5 mm do not adversely affect the bending result.
