Description

Vorrichtung zum Herstellen von Lochungen in gedruckten SchaltungenDevice for producing perforations in printed circuits

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Lochungen in gedruckten Schaltungen für den Anschluß der Kontakte elektrischer Bauelemente.The invention relates to a device for producing perforations in printed circuits for connecting the contacts of electrical components.

Bekanntlich werden gedruckte Schaltungen aus kupferbeschichtetem Isoliermaterial hergestellt, gewöhnlich aus kupferbeschichtetem Epoxyd-Harz mit Giasfaserverstärimg. Die Leiterbahnen, die auf der Platte stehenbleiben sollen, werden obgedeckt und der Rest des Kupfers weggeätzt in solche fertiggestellte gedruckte Schaltungen müssen dann noch die Bestuckungs löcher für die elektrischen Bauelemente gebohrt werden. Die Anschlußdrähte dieser Bauelemente werden durch die Bestückungsldcher gesteckt und mit den Kupferleiterbahnen verlötet. Die so hergestellten gedruckten Schaltungen zeichnen sich durch eine gute mechanische Stabilität und eine hohe Betriebssicherheit aus. Beim Entwurf von gedruckten Schaltungen werden bereits die Positionen für die Bestückungslöcher markiert0 Ehe gedruckte Schaltungen in die Großserienfertigung gehen, werden zunächst Schaltungsmwter hergestellt, wobei die Bestuckungslöcher bei der Mwterfertigung nur manuell gebohrt werden können. Jede Lochmarkierung muß manuell in dem Bereich eines Bohr- oder Stanzwerkzeuges geführt werden, so daß das Bohren der Löcher der arbeitsintensivste und arbeitsaufwendigste Teil bei der Herstellung von gedruckten Schaltungen darstellt.It is known that printed circuits are made of copper-coated insulating material made, usually from copper-coated epoxy resin with glass fiber reinforcement. The conductor tracks that are to remain on the plate are covered and the rest of the copper must have been etched away in such finished printed circuit boards then the assembly holes for the electrical components are drilled. The connecting wires of these components are inserted through the mounting holes and soldered to the copper conductor tracks. The printed circuits produced in this way are characterized by good mechanical stability and high operational reliability the end. When designing printed circuits, the positions for the Placement holes marked0 before printed circuits go into large-scale production go, Schaltungsmwter are first made, with the mounting holes can only be drilled manually during manufacturing. Every hole mark must be performed manually in the area of a drilling or punching tool, so that the Drill the holes are the most labor-intensive and labor-consuming part of the manufacturing process of printed circuits.

Das Bohren der Bestuckungslöcher für die Herstellung von Großserie wird durch numerisch gesteuerte Werkzeugmaschinen ausgefuhrt, nachdem vorher die Koordinaten der Löcher auf Lochstreifen oder ein anderes Speichermedium gespeichert worden sind. Die numerisch gesteuerte Bohrmaschine fahrt dann die jeweiligen Lochpositionen automatisch ab. Dieses Verfahren ist nur sinnvoll bei Fertigung von größeren Serien, da die Erfassung von Löcher-Koordinaten auf Lochstreifen oder Magnetband sehr arbeitsintensiv und daher sehr teuer ist.The drilling of the equipping holes for the production of large series is carried out by numerically controlled machine tools, after previously having the Coordinates of the holes saved on punched tape or another storage medium have been. The numerically controlled drilling machine then moves to the respective hole positions automatically off. This process is only useful for the production of larger series, because the recording of hole coordinates on punched tape or magnetic tape is very labor-intensive and is therefore very expensive.

Der Erfindung liegt daher die Aufgabe zugrunde, mit einfachen Mitteln eine Vorrichtung zu schaffen, mit der auch die Herstellung von Mustern gedruckter Schaltungen schnell und wirtschaftlich sowie mit der gewünschten Präzision möglich ist.The invention is therefore based on the object with simple means to create a device with which the production of printed patterns Switching is possible quickly and economically as well as with the desired precision is.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen den Schaltungströger aufnehmenden, relativ zu einem Bohr- oder Stanzwerkzeug beweglichen Führungsschlitten und eine ueber dem Schaltungströger angeordnete, auf von den zu lochenden Scha ltplanste 1 len ausgehenden Helligkeitswerten ansprechende Optik, die mit einem von den abgetasteten Werten gesteuerten Programmsteuergeröt verbunden ist, das seinerseits den Antrieb fur den Fuhrungsschlitten und das Bohr- oder Stanzwerkzeug programmgemäß steuert.According to the invention, this object is achieved by a circuit carrier receiving, relative to a drilling or punching tool movable guide carriage and one above the circuit board, on the circuit board to be punched 1 len outgoing brightness values appealing optics, which with one of the scanned Values controlled program control unit is connected, which in turn controls the drive for the guide carriage and the drilling or punching tool according to the program.

Vorzugsweise ist die auf Helligkeiftwerte ansprechende Optik durch eine Punktrasteroptik gebildet. Der vom Programmsteuergeröt gesteuerte Antrieb für die FUhrungsschlitten ist durch zwei Schrittmotore gebildet.The optics which respond to brightness values are preferably through formed a dot grid optics. The drive controlled by the program control unit for the guide carriage is formed by two stepper motors.

Der Erfindungsgedanke, der die verschiedensten Ausführungsmöglichkeiten zuläßt, ist in der beiliegenden schematischen Darstellung näher erläutert0 Die Vorrichtung besteht aus einem Führungsschlitten 1, 2, i; wobei der den Schaltungsträger 3 aufnehmende Rahmen 1 durch einen Schrittmotor My in der Y-Richtung verschiebbar ist und im Rahmen 2 lagert0 Der Rahmen 2 ist ebenfalls von einem Schrittmotor Mx im Rahmen 1 1n der X-Richtung verschiebbar0 Beide Schrittmotore My und Mxstnd Uber Leitungen 6,8 mit einem Rechengerät verbunden, welches die Schrittmotore My und Mx programmgemäß so steuert, daß die einzelnen Abschnitte des Schaltungsträgers an einer Optik O vorbeigeführt werden, welche auf die von den Markierungen 4 ausgehenden Helligkeitswerte anspricht. Die Markierungen 4 geben jeweils die Position an, in der eine Lochung erfolgen soll0 Vorzugsweise gelangt eine 16>c16 Punktrasteroptik zur Anwendung. Befindet sich eine Markierung 4 im Bereich der Optik O, so gibt diese die Helligkeitswerte an den Rechner weiter, welcher programmgemäß die genaue Position des zu bohrenden Loches berechnet und über die Leitung 9 den Bohrer B veranlaßt, eine Lochung 4herzustellen0 Programmgemäß wird dann ein anderer Abschnitt des Schaltungsträgers 3 in den Bereich der Optik O geführt, so daß nach und nach der gesamte Schaltungsträger 3 von der Optik O abgetastet wird und die zu bohrenden Löcher 4 automatisch hergestellt werden .The idea of the invention, the most diverse implementation possibilities allows, is explained in more detail in the attached schematic representation0 The device consists of a guide carriage 1, 2, i; wherein the circuit carrier 3 receiving Frame 1 is displaceable in the Y direction by a stepper motor My and in the frame 2 stores0 The frame 2 is also from a stepper motor Mx in the frame 1 1n X-direction can be shifted 0 Both stepper motors My and Mxstnd via cables 6,8 with connected to a computing device, which the stepper motors My and Mx according to the program controls that the individual sections of the circuit board are guided past an optical system O. which responds to the brightness values emanating from the markings 4. The markings 4 each indicate the position in which a hole is to be made0 A 16> c16 point grid optics are preferably used. Is located a marking 4 in the area of the optics O, this indicates the brightness values the computer, which according to the program the exact position of the hole to be drilled calculated and causes the drill B via the line 9 to produce a hole 40 According to the program, another section of the circuit carrier 3 is then placed in the area the optics O out, so that gradually the entire circuit board 3 of the Optics O is scanned and the holes 4 to be drilled are made automatically .
