PCB Conveyor

Flexible Dual Conveyor

Description

The PCB dual conveyor can

greatly increase throughput

with shorter down times -

depending on the placement

program. It allows two PCBs

to be carried simultaneously

(synchronously) or alternate-

ly (asynchronously) through

the placement machine.

In asynchronous mode, only

one PCB in a transport track is

processed. At the same time,

another PCB in the second

transport track is moved into

the placement position.

This saves the full conveying

time of one PCB, thus consid-

erably increasing perfor-

mance, particularly for PCBs

with a short cycle time.

The placement process starts

as soon as one PCB is trans-

ported into the processing

area.

In synchronous mode, two

PCBs are moved into the

placement position at the

same time. They are pro-

cessed as a common panel.

In this way, the top and bot-

tom of a PCB can be pro-

cessed on a single line. The

proportion of non-productive

time is reduced as two circuit

boards are always conveyed

simultaneously.

With the flexible dual convey-

or, one conveyor track may

spread further than the stan-

dard width of 216 mm in sin-

gle conveyor mode. The

side panels of the second

conveyor track are moved

fully together and the second

conveyor track is disabled.

This allows overwide PCBs to

be processed in machines

with a dual conveyor.
