Abstract

A method is proposed for automatically fitting components to printed-circuit boards (10). The components are inserted with their connecting wires (12) into holes (13) which are located in the printed-circuit board (10). This takes place in that in each case one auxiliary wire (14) is guided from below through the relevant hole (13) in the printed-circuit board (10) as far as a specific auxiliary joining plane (15) which runs parallel to the printed-circuit board (10) and is above said printed-circuit board (10), in that the upper end of the auxiliary wire (14) is fixed in this auxiliary joining plane (15), in that the component is guided from above with one of its connecting wires (12) onto the auxiliary wire (14) and is fixed in the auxiliary joining plane (15) in such a manner that it is aligned with the auxiliary wire (14), in that both wires (12, 14) are then connected to one another in the auxiliary joining plane (15), in that the fixing (16, 17) of both wires (12, 14) is at this point released and the connecting wire (12) of the component is pulled through the hole (13) in the printed-circuit board (10) with the aid of the auxiliary wire (14), in that, at this point, the joined-together wire consisting of the connecting wire (12) and the auxiliary wire (14) is cut through in such a manner that the length of the wire section remaining on the component corresponds to the fitment instructions and the remaining other part of the wire (12, 14) which has been cut through can be used again as an auxiliary wire for a joining process which is to be carried out in the same manner. <IMAGE>

Die Bauelemente 11 sind mit ihren Anschlußdrähten 12 durch in der Leiterplatte 10 angebrachte Bohrungen hindurchgeführt, wobei diese Anschlußdrähte 12 mit nicht dargestellten Leiterbahnen, die sich an der Unterseite der Leiterplatte befinden, in ebenfalls nicht dargestellter Weise verlötet sind. Der Abstand zwischen zwei einander unmittelbar benachbarten Anschlußleitern 12 ist mit 2,5 mm angegeben. Eine Leiterplatte mit einem derartig niedrigen Rastermaß läßt sich mit den bisher bekannten Verfahren automatisch nicht bestücken.Description of the exemplary embodiment In Figure 1 is a circuit board 10, which is equipped with components 11. The components 11 are with their connecting wires 12 passed through holes made in the circuit board 10, these connecting wires 12 with conductor tracks, not shown, which are attached to located on the underside of the circuit board, in a manner also not shown are soldered. The distance between two directly adjacent connecting conductors 12 is given as 2.5 mm. A circuit board with such a low grid dimensions cannot be automatically achieved with the previously known methods equip.

Um dies zu erreichen, wird, wie in Figur 2 schematisch angedeutet, oberhalb der Leiterplatte 10 eine Hilfsfügeebene 15 eingeführt.In order to achieve this, as indicated schematically in FIG. 2, An auxiliary joining plane 15 is introduced above the circuit board 10.

Aus Figur 3 ist zu erkennen, wie das erfindungsgemäße Verfahren im einzelnen auszuführen ist. Die Leiterplatte ist wieder mit 10 bezeichnet. Die Bohrung, in die der Anschlußdraht 12 eines Bauelements einzuführen ist, ist mit 13 bezeichnet. Erfindungsgemäß wird durch die Bohrung 13 von unten her ein Hilfsdraht 14 hindurchgeführt und so weit nach oben geschoben, bis sein oberes Ende die Hilfsfügeebene 15 erreicht. Dann wird mit Hilfe der Fixierungsmittel 17 das obere Ende des Hilfsdrahts 14 in dieser Hilfsfügeebene 15 fixiert.From Figure 3 it can be seen how the inventive method in is to be carried out individually. The circuit board is again designated by 10. The hole into which the connecting wire 12 of a component is to be inserted is denoted by 13. According to the invention, an auxiliary wire 14 is passed through the bore 13 from below and pushed up until its upper end reaches the auxiliary joining plane 15. Then, with the aid of the fixing means 17, the upper end of the auxiliary wire 14 in this auxiliary joining plane 15 is fixed.

Hierauf wird von oben her das Bauelement mit einem seiner Anschlußdrähte 12 an den Hilfsdraht 14 herangeführt.
