PCB Conveyor
Overview
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
circuit 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.
Flexible dual conveyor
To keep the range of PCBs to
be processed as wide as
possible - whilst maintaining
maximum productivity - the
flexible SIPLACE dual con-
veyor allows you to choose
between single conveyor
mode and dual conveyor
mode.
In dual conveyor mode, two
PCBs are moved into the
placement machine and
placed either simultaneously
(synchronous operation) or
alternately (asynchronous
operation).
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, par-
ticularly for PCBs with a short
cycle time. The placement
process starts as soon as one
PCB is transported into
the processing
area.
Conveyor buffer
SIPLACE PCB conveyors have
buffer zones. If shorter wait-
ing times occur in a place-
ment area (due to longer
cycle times in the oven, for
example), the downstream
placement areas can con-
tinue to work since the unaf-
fected area can easily access
the PCB that is waiting in the
buffer zone. This increases
the true output of the place-
ment line.
