Description
For placement, the PCB is
clamped from below. The dis-
tance between the top of the
PCB and the placement head
thus remains unchanged for
each PCB, and is not depen-
dent on the thickness of the
PCB. The placement rate is
also independent of the PCB
thickness.
Since the distance between
the PCB surface and the PCB
camera remains the same,
the PCB camera is always
focussed on the PCB surface
with the same level of sharp-
ness.
The PCB fiducial contours
are optimally mapped on the
CCD chip of the PCB camera.
The inline PCB conveyor sys-
tem quickly adapts to a wide
range of PCB widths.
The setting is made using the
placement program or via
the station software menu.
The width of the PCB con-
veyor is monitored by an in-
tegral control circuit.
The machine height can be
modified, thus allowing the
machines to be integrated
into lines with a transport
height of 830, 900, 930 or
950 mm.
The PCB conveyors of the in-
dividual machines communi-
cate via the SMEMA interface
(optional Siemens interface).
The fixed transport side can
be located on the left or right
for both the dual conveyor
and the single conveyor.
With this conveyor, the fixed
side can be easily switched
from right to left or vice
versa.
Movement and clamping of
the PCBs are monitored.
When the board has reached
the placement area and
passed the light barrier, it is
braked. A laser light barrier
determines the position of
the board. As soon as the cir-
cuit board has reached its tar-
get position, the conveyor
belt is stopped and the board
is clamped from the under-
side. The placement process
then starts immediately.
