Abstract

The separation device is used to separate a printed circuit board, provided with conductor paths and attached circuit components for a number of identical or different modules, into its separate parts, using a horizontal support plate (8) and a cutting device with a stationary blade edge (16) and a relatively displaced cutting edge (17). The support plate is attached to a lifting device (2,3), for vertical displacement of the support plate, pref. using a carriage (2) driven by a horizontal spindle (3), with an angled bearing ramp for the support plate.

Description

Elektronische Flachbaugruppen werden häufig in sogenannten Nutzen hergestellt, d. h. in der Weise, daß eine Leiterplatte mit den Leiterbahnen für mehrere gleiche oder auch unter­ schiedliche Baugruppen versehen, mit Bauelementen bestückt und erst dann in die einzelnen Baugruppen unterteilt wird, wozu eine Trennvorrichtung eingesetzt wird. Dabei tritt das Problem auf, daß die Bauelemente unterschiedliche Höhen ha­ ben.Electronic printed circuit boards are often used in so-called Benefits produced, d. H. in the way that a circuit board with the conductor tracks for several of the same or under Different assemblies provided, equipped with components and only then divided into the individual assemblies, what a separator is used for. This occurs Problem on that the components ha different heights ben.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Trennvorrichtung für bestückte Leiterplatten zu schaffen, die leicht an unterschiedliche Bauelementehöhen angepaßt werden kann. Erfindungsgemäß wird diese Aufgabe mit den im An­ spruch 1 angegebenen Maßnahmen gelöst.The present invention has for its object a Separator for assembling printed circuit boards to create the can be easily adapted to different component heights can. According to the invention, this task is performed with the in 1 specified measures solved.

Im allgemeinen ist die Schneidvorrichtung feststehend und die Auflageplatte in der Höhe verstellbar, d. h., der Abstand der Auflageplatte von der Schneidkante ist einstellbar. Die Lei­ terplatte kann daher mit Bauelementen nach unten auf die Auf­ lageplatte gelegt werden und ist dennoch in einer für das Trennen geeigneten Position. Es können daher auch beidseitig mit Bauelementen bestückte Leiterplatten getrennt werden.In general, the cutter is fixed and the Height-adjustable platen, d. that is, the distance of the Platen from the cutting edge is adjustable. The lei terplatte can therefore with components down on the on layer plate and is still in one for that Separate appropriate position. It can therefore also be bilateral PCBs equipped with components can be separated.

Anhand der Zeichnung, in der ein Ausführungsbeispiel der Er­ findung dargestellt ist, werden im folgenden die Erfindung sowie Ausgestaltungen und Weiterbildungen näher beschrieben und erläutert.Based on the drawing, in which an embodiment of the Er invention is shown, the following are the invention as well as refinements and developments described in more detail and explained.

In den Fig. 1 und 2 sind zwei Teilschnitte eines Ausfüh­ rungsbeispiels dargestellt.In Figs. 1 and 2, two sections of a part exporting are shown approximately example.

Mit 1 ist ein wannenförmiges Unterteil eines Gehäuses be­ zeichnet, in dem eine heb- und senkbare Auflageplatte 8 für Leiterplatten angebracht ist. Diese ruht über zwei Stützen 6, 7 auf einem Schlitten oder einem Wagen 2, durch den eine Spindel 3 läuft, die an ihren Enden zweckmäßig an gegenüber­ liegenden Gehäusewänden gelagert und mit einer Kurbel 33 ver­ sehen ist. Sie greift in Spindelmuttern 30, 31 ein, die im Wagen 2 sitzen. Durch Drehen der Spindel kann der Wagen hin- und herbewegt werden. Anschläge 22, 23 begrenzen die Bewegung des Wagens 2. An den unteren Enden der Stützen 6, 7 sind Rol­ len 26, 27 angebracht, mit denen die Stützen während der Be­ wegung des Wagens 2 auf zwei Schrägen 4, 5 an den beiden Sei­ ten des Wagens laufen. Die Stützen und damit die Auflage­ platte 8 werden damit je nach Drehrichtung der Kurbel 33 ge­ hoben oder gesenkt. In durchgezogenen Linien sind die Hub­ vorrichtung und die Auflageplatte in deren untersten Position dargestellt. In Fig. 1 ist in gestrichelten Linien die ober­ ste Position der Auflageplatte skizziert. 1 with a trough-shaped lower part of a housing is characterized, in which a liftable and lowerable support plate 8 is attached for printed circuit boards. This rests on two supports 6 , 7 on a carriage or a carriage 2 , through which a spindle 3 runs, which at its ends is appropriately mounted on opposite housing walls and is seen with a crank 33 . It engages in spindle nuts 30 , 31 , which are located in carriage 2 . The carriage can be moved back and forth by turning the spindle. Stops 22 , 23 limit the movement of the carriage 2 . At the lower ends of the supports 6 , 7 are Rol len 26 , 27 attached, with which the supports run during the loading movement of the carriage 2 on two slopes 4 , 5 at the two sides of the carriage. The supports and thus the support plate 8 are raised or lowered depending on the direction of rotation of the crank 33 ge. The lifting device and the platen are shown in their lowest position in solid lines. In Fig. 1, the top position of the platen is outlined in broken lines.

Zur Führung der Auflageplatte 8 sind an ihr Zylinder 11, 12, 29 sowie ein in den Fig. 1 und 2 nicht sichtbarer Zylinder befestigt, in die Säulen 9, 10, 28 sowie eine nicht sichtbare Säule eingreifen, die auf dem Boden des Unter­ teils 1 sitzen. Für ein sicheres Absenken der Auflageplatte 8 sorgen Zugfedern 13, 14.To guide the support plate 8 are attached to their cylinders 11 , 12 , 29 and a cylinder not visible in FIGS. 1 and 2, engage in the columns 9 , 10 , 28 and an invisible column, which on the bottom of the lower part 1 sit. Tension springs 13 , 14 ensure a safe lowering of the support plate 8 .

Eine Rollenschere besteht aus einem feststehenden Messer 16 mit einer geraden Schneide, das an einer Halterung 15 be­ festigt ist und durch einen Schlitz in der Auflageplatte 8 nach oben ragt. Gegenüber der Schneide des feststehenden Mes­ sers 16 befindet sich die Schneide eines Kreismessers 17, das an einem Schlitten 19 angebracht ist. Dieser ist von parallel zur Schneide des feststehenden Messers 16 verlaufenden Schie­ nen 18 geführt und kann mittels eines Handgriffs 20 verscho­ ben werden. An der der Schneidvorrichtung benachbarten Kante der Auflageplatte 8 ist eine Rutsche 21 angelenkt, über wel­ che die abgetrennten Teile abgeführt werden. A roller shear consists of a fixed knife 16 with a straight edge, which is fastened to a bracket 15 be and protrudes through a slot in the platen 8 upwards. Opposite the cutting edge of the fixed knife 16 is the cutting edge of a circular knife 17 which is attached to a carriage 19 . This is guided by parallel to the cutting edge of the fixed knife 16 sliding rails 18 and can be moved by means of a handle 20 ben. At the edge of the support plate 8 adjacent to the cutting device, a slide 21 is articulated, via which the separated parts are removed.

Die zu trennenden Leiterplatten werden mit Bauelementen nach unten auf die Auflageplatte 8 gelegt. Diese kann mittels der Spindel 3 in eine solche Position gebracht werden, daß unab­ hängig von der Höhe der Bauelemente die Leiterplatte horizon­ tal, d. h. senkrecht, zu den Messern 16, 17 liegt. Selbstver­ ständlich können mit der neuen Vorrichtung auch unbestückte Leiterplatten getrennt werden, wozu die Auflageplatte 8 in die oberste Position gefahren wird.The circuit boards to be separated are placed on the support plate 8 with the components facing downward. This can be brought into such a position by means of the spindle 3 that, independently of the height of the components, the circuit board is positioned horizontally, ie perpendicularly, to the knives 16 , 17 . Of course, unassembled circuit boards can be separated with the new device, for which purpose the platen 8 is moved into the uppermost position.
