Trennvorrichtung für vorgeritzte LeiterplattennutzenSeparating device for pre-scored PCB panels

Die Erfindung bezieht sich auf eine Trennvorrichtung für vorgeritzte Leiterplattennutzen, mit zwei sich in einer gemeinsamen, senkrechten Trennebene gegenüberstehenden, in die V-förmigen Ritzgräben der Leiterplattennutzen eingreifenden Trennwerkzeugen.The invention relates to a separating device for pre-scored printed circuit board panels, with two separating tools that are located opposite one another in a common, vertical separating plane and engage in the V-shaped scoring grooves of the printed circuit board panels.

Die Außenkontur von Leiterplatten wird immer häufiger in Kerb-Ritz-Fräs-Technik hergestellt. Die Vorteile der Nutzenverarbeitung enden spätestens nach dem Löten und Testen der Schaltungen. Beim Auseinanderbrechen der SMD-Baugruppen entstehenden durch Oberflächenspannungen Defekte in den Lötstellen, die einem Alterungsprozeß unterliegen und zum Totalausfall der Schaltung führen können.The outer contour of circuit boards is increasingly being manufactured using notch-scratch-milling technology. The advantages of panel processing end at the latest after soldering and testing of the circuits. When the SMD assemblies break apart, surface tensions cause defects in the soldering points, which are subject to an aging process and can lead to total failure of the circuit.

Die Glasfasern im Reststeg werden teilweise durch die beim Brechen auftretenden Zugspannungen gerissen. Dadurch stehen Glasfaserbündel an der Bruchkante hervor.The glass fibers in the remaining web are partially torn by the tensile stresses that occur during breaking. This causes glass fiber bundles to protrude at the breaking edge.

Es sind in der Praxis Trennvorrichtungen bekannt geworden, die mit keilförmigen Trennwerkzeugen arbeiten, welche in die sich gegenüberliegenden Ritzgräben eingreifen und von denen ein Trennwerkzeug gegenüber dem anderen Trennwerkzeug zum Trennvorgang höhenbewegt wird, was praktisch ein Keilspalten ergibt. Hierbei haben jedoch die Einzelnutzen nicht die gewünschten sauberen und glatten Trennkanten. Außerdem istIn practice, separating devices have become known that work with wedge-shaped separating tools that engage in the opposing scoring grooves and of which one separating tool is moved in height relative to the other separating tool for the separating process, which practically results in wedge splitting. However, the individual panels do not have the desired clean and smooth separating edges. In addition,

■■'2■■'2

der Antriebsmechanismus für die Höhenbewegung des Trennwerkzeuges verhältnismäßig aufwendig.The drive mechanism for the vertical movement of the cutting tool is relatively complex.

Aufgabe der Erfindung ist es, eine Trennvorrichtung zu schaffen, die bei einfachem Aufbau und bequemer Handhabung sowie günstig gestalteter und optimal wirkender Trennwerkzeuge ein einwandfreies, sauberes Trennen der Leiterplatten in Einzelnutzen ermöglicht.The object of the invention is to create a separating device which, with a simple structure and convenient handling, as well as inexpensively designed and optimally effective separating tools, enables a perfect, clean separation of the circuit boards into individual panels.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das eine Trennwerkzeug von einem unteren feststehenden Linearmesser und das andere Trennwerkzeug von einem an einer Führung (Linearführung) in Längsrichtung des Linearmessers verschiebbar gehaltenen, zum Nutzentrennen im Ritzgraben abrollenden Messerrad gebildet ist.This object is achieved according to the invention in that one separating tool is formed by a lower fixed linear knife and the other separating tool is formed by a knife wheel which is held on a guide (linear guide) so as to be displaceable in the longitudinal direction of the linear knife and rolls in the scoring groove for panel separation.

In den Unteransprüchen sind Gestaltungsmerkmale enthalten, die vorteilhafte und förderliche Weiterbildungen der Aufgabenlösung darstellen.The subclaims contain design features that represent advantageous and beneficial further developments of the task solution.

Die Trennvorrichtung ist einfach und kostengünstig aufgebaut, zeigt eine leichte Handhabung und ermöglicht aufgrund ihrer besonders gestalteten Trennwerkzeuge als feststehende Linearmesser und abrollendes Messerrad ein einwandfreies, sauberes Trennen der Leiterplatten in Einzelnutzen.The separating device is simple and cost-effective, is easy to handle and, thanks to its specially designed separating tools as a fixed linear knife and a rolling knife wheel, enables the circuit boards to be separated cleanly and flawlessly into individual panels.

Der Leiterplattenzuschnitt wird mit seiner Sollbruchstelle (unterem Ritzgraben) lose auf das untere feststehende Linearmesser aufgelegt. Das obere Rundmesser rollt beim Ziehen der Linearführung in der Ritzgeometrie (des oberen Ritzgraben) ab und trennt dabei den Zuschnitt an dieser Stelle. Oberflächenspannungen können nicht entstehen, und es entsteht eine saubere (glatte) Schnittkante.The circuit board blank is placed loosely on the lower fixed linear knife with its predetermined breaking point (lower scoring groove). When the linear guide is pulled, the upper circular knife rolls along the scoring geometry (of the upper scoring groove) and separates the blank at this point. Surface tension cannot arise and a clean (smooth) cutting edge is created.

Die beiden Messer sind von verschleißfesten und nachschleifbaren HSS-Messern gebildet. Durch das feststehende und das rollende Messer werden die Glasfasern in den Leiterplatten geschert, wodurch keine hervorstehenden Glasfaserbündel entstehen können, sondern die Schnittkante wird sauber und glatt.The two blades are made of wear-resistant and regrindable HSS blades. The fixed and rolling blades shear the glass fibers in the circuit boards, which means that no protruding glass fiber bundles can form, and the cutting edge is clean and smooth.

Die kompakte, kugelgelagerte Längsführung des Messerrades ergibt eine stabile Lagerung, einen genauen und ruhigen Lauf für das Messerrad.The compact, ball-bearing longitudinal guide of the knife wheel provides stable support and precise, smooth running for the knife wheel.

Dem rotierenden Messerrad ist ein Handschutz zugeordnet, der zur Unfallverhütung das Messer bis auf den in den Ritzgraben eingreifenden Bereich abdeckt und eine Sicherheitssvorrichtung darstellt.The rotating blade wheel is fitted with a hand guard which covers the blade except for the area that reaches into the cutting groove to prevent accidents and which represents a safety device.
