PCB Conveyor
Single Conveyor and Dual Conveyor
Conveyor principle
If the board has reached the
placement area and passed
a light barrier, it is braked. An
additional laser light barrier
determines the position of
the board. As soon as the cir-
cuit board has reached its
target position, the conveyor
belt is stopped and the board
is clamped from below. The
placement process then
starts immediately. Move-
ment and clamping of the
PCBs are monitored.
The conveyor can be easily
matched to many different
PCB widths by the automatic
electrical width adjustment.
The fixed conveyor rail may
be located on the left or right
for both the flexible dual con-
veyor and the single con-
veyor.
Single conveyor
On the single conveyor,
PCBs are moved one after
the other into the placement
machine and placed on a
conveyor track. This con-
veyor variant is particularly
suitable for very wide PCBs.
Flexible dual conveyor
To keep the range of PCBs to
be processed as wide as
possible - whilst maintaining
maximum productivity -
the flexible SIPLACE
dual conveyor
allows you to
choose between single con-
veyor mode and dual con-
veyor mode.
In dual conveyor mode, two
PCBs are moved into the
placement machine and
placed either simultaneously
(synchronous operation)
or alternately (asyn-
chronous opera-
tion).
In synchronous mode,
two PCBs are moved into
the placement position at the
same time. They are pro-
cessed as a common panel.
This allows the top and bot-
tom of PCB to be processed
on the same line and, for
products with very different
components to be placed,
the common optimization of
all the components to be
placed on both PCBs makes
it possible to increase output.
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 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.
Conveyor buffer
SIPLACE PCB conveyors
have three buffer zones. If
shorter waiting times occur in
a placement area (due to lon-
ger cycle times in the oven,
for example), the down-
stream placement areas can
continue to work since the
unaffected area can easily
access the PCB that is wait-
ing in the buffer zone. This
increases the true output of
the placement line.
