Beschreibung
BestückautomatDescription
Placement machine

Die Erfindung betrifft einen Bestückautomat gemäß dem Oberbegriff des Schutzanspruchs 1.The invention relates to a placement machine according to the preamble of claim 1.

Ein solcher Bestückautomat ist beispielsweise ein modulares SMD-Hochleistungs-Bestücksystem zur Bestückung von Leiterplatten mit SMD-Bauelementen. Der Bestückautomat weist beispielsweise zwei Revolverbestückungsköpfe auf, die beidseitig des Transportsystems für die Leiterplatten angebracht sind. Die Bauelemente sind ebenfalls beidseitig zum Transportsystem in einer Bauelementezuführung bevorratet. Die Bauelemente können hierbei gurtförmig, stangenförmig oder als Schüttgut bevorratet sein.One such placement machine is, for example, a modular SMD high-performance placement system for assembling circuit boards with SMD components. The placement machine has, for example, two turret placement heads that are attached to both sides of the transport system for the circuit boards. The components are also stored on both sides of the transport system in a component feeder. The components can be stored in belt form, rod form or as bulk goods.

Zu Bestückung wird die Leiterplatte programmgesteuert durch das stufenlos breitenverstellbare Transportbandsystem in.denFor assembly, the circuit board is program-controlled by the continuously adjustable conveyor belt system in the

0 Automaten eingefahren. Nach der Leiterplatten-Klemmung zur 0 machines retracted. After the circuit board clamping to the

exakten Fixierung nehmen die Revolverbestückungsköpfe abwechselnd Bauelemente auf, verfahren zur Leiterplatte und bestükken diese. Der erste Revolverbestückungskopf kann seine gesammelten und gegebenenfalls elektrisch geprüften Bauelemente bestücken, um anschließend dem zweiten Kopf Platz zu machen, der dann seinerseits seine Bauelemente auf die Leiterplatte bestückt. Mit den beiden Revolverbestückungsköpfen ist praktisch eine ununterbrochene Bestückung der Leiterplatte möglich. Wenn eine Leiterplatte fertig bestückt ist, 0 wird sie aus dem Bestückautomaten herausgefahren, und gleichzeitig eine weitere Leiterplatte hineintransportiert. Einer der beiden Revolverbestückungsköpfe wartet hierbei auf die Leiterplatte und erfaßt ihre genaue Lage.The turret assembly heads take turns picking up components, moving to the circuit board and assembling them. The first turret assembly head can assemble its collected and, if necessary, electrically tested components, and then make way for the second head, which then assembles its components onto the circuit board. With the two turret assembly heads, it is practically possible to assemble the circuit board continuously. When a circuit board has been assembled, it is moved out of the assembly machine and another circuit board is transported in at the same time. One of the two turret assembly heads waits for the circuit board and detects its exact position.

Ein typischer Bestückungszyklus dauert ca. 250 ms. Die Nebenzeit, in der beispielsweise der Leiterplattenwechsel erfolgt,A typical assembly cycle takes about 250 ms. The idle time, during which, for example, the circuit board change takes place,

958)812958)812

beträgt ca. drei Sekunden pro Leiterplatte. In dieser Zeitspanne könnten angenähert 10 Bauelemente bestückt werden.is approximately three seconds per circuit board. In this time, approximately 10 components could be assembled.

Der Erfindung liegt die Aufgabe zugrunde einen Bestückungsautomaten der.eingangs benannten Art derart weiterzubilden, so daß diese Nebenzeiten verkürzt werden.The invention is based on the object of developing a pick-and-place machine of the type mentioned at the outset in such a way that these idle times are shortened.

Diese Aufgabe wird erfindungsgemäß durch die im Schutzanspruch 1 angegebenen Merkmale gelöst. 10This object is achieved according to the invention by the features specified in claim 1. 10

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles beschrieben.In the following, the invention is described using an embodiment shown in the drawing.

In der einzigen Figur ist ein Bestückautomat BA mit einem Transportbandsysteme TPl dargestellt. Mit dem Transportbandsysteme TPl werden Leiterplatten LPl in den Bestückautomaten BA eingefahren.The only figure shows a BA placement machine with a conveyor belt system TPl. The conveyor belt system TPl is used to feed circuit boards LPl into the BA placement machine.

Erfindungsgemäß ist ein weiteres, gleichartiges Transport-0 bandsysteme TP2 vorgesehen, so daß parallel zum Bestückungsvorgang auf der Leiterplatte LpI auf dem Transportbandsystem TPl eine weitere Leiterplatte LP2 mit dem Transportbandsystem TP2 in den Bestückautomaten BA eingefahren werden kann. Die Leiterplatten LPl, LP2 werden über ein Verteilsystem VT jeweils auf eines der beiden Transportbandsysteme TPl oder TP2 transportiert.According to the invention, a further, similar conveyor belt system TP2 is provided so that, parallel to the assembly process on the circuit board LpI on the conveyor belt system TP1, another circuit board LP2 can be fed into the assembly machine BA using the conveyor belt system TP2. The circuit boards LP1, LP2 are each transported to one of the two conveyor belt systems TP1 or TP2 via a distribution system VT.

Der Bestückautomat BA weist in bekannter Weise zwei Revolverbestückungsköpfe RKl, RK2 auf, die beidseitig zu den Transportbandsystemen TPl, TP2 angeordnet sind. Jeder dieser Revolverbestückungsköpfe RKl, RK2 nimmt Bauelemente aus einer Bauelementezuführung BEI, BE2 auf, und transportiert sie zur gerade zu bestückenden Leiterplatte LPl oder LP2.As is known, the BA assembly machine has two turret assembly heads RKl, RK2, which are arranged on both sides of the conveyor belt systems TPl, TP2. Each of these turret assembly heads RKl, RK2 takes components from a component feeder BEI, BE2 and transports them to the circuit board LPl or LP2 that is currently being assembled.

Durch das erfindungsgemäß ausgebildete "zweigleisige" Transportbandsystem TPl, TP2 kann eine Leiterplatte LP2 in den Bestückautomaten BA transportiert werden, während die vorher-The "two-track" conveyor belt system TP1, TP2 designed according to the invention enables a printed circuit board LP2 to be transported into the assembly machine BA, while the previous
