Description
The 6-Nozzle placement head
operates on the Collect & Place
principle. In contrast to classic
chip shooters, the 6 vacuum
nozzles of the SIPLACE Collect
& Place head rotate around a
horizontal axis. This does not
only save space:
Due to the small diameter com-
pared to chip shooters, the cen-
trifugal forces are significantly
lower. The results are high-speed,
reliable placement and the same
cycle time for all components.
Components are picked up and
placed reliably with the aid of vac-
uum followed by a gentle air kiss.
A number of vacuum tests moni-
tors if the component has been
picked up and placed accurately.
Various control and self-learning
functions further enhance the de-
pendability of the system:
§ The optical recognition of feeder
positions records the exact posi-
tion of the feeder table.
§ A camera on the placement head
(component vision module) de-
termines the exact position of
each component on the nozzle.
§ For every feeder the pick-up
offsets are averaged over the
last ten pick-ups. This enables
the head to dial-in on the pre-
cise pick point for each compo-
nent.
§ In addition, the package form is
also checked. If the actual geo-
metric dimensions of the com-
ponent do not correspond to
those programmed, the compo-
nent is rejected.
§ Components rejected by the
vision system are dumped into
a bin. Any rejected component
gets automatically placed during
a repair run.
§ Warpage of the PCB is accom-
modated by sensor stop acti-
vated z-axis placement. The sys-
tem also keeps the last ten
positions of the z-axis at com-
ponent placement and uses the
average of these values to im-
prove the drive down and place
speed of the cycle.

Description
A nozzle changer corresponding to
the Collect & Place Head in use
can be installed to the left of the
PCB conveyor with no loss of
feeder capacity. It will change the
nozzle set-up of the placement
head quickly and reliably for the
specific nozzle configuration valid
to a job. Damaged or faulty nozzles
can be exchanged via the menu
function on the station computer.
