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 while another PCB
in the second transport track
is moved into the placement
position. This saves the full
conveying time of one PCB,
thus considerably increasing
performance, 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.
