Description
The 12-Nozzle placement head op-
erates on the Collect & Place prin-
ciple. In contrast to classic chip
shooters, the 12 vacuum nozzles
of the SIPLACE Collect & Place
head rotate around a horizontal
axis. In addition to space savings
this offers the following benefits:
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 precise
pick point for each component.
§ 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 vi-
sion system are dumped into a
bin, reject feeder or matrix tray.
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 maximum of 2 nozzle changers
can be installed for each of the
12-Nozzle Collect & Place Heads,
which allows for 120 unique noz-
zles per Collect & Place Head
without decreasing feeder quanti-
ties. This allows a quick and reli-
able change of the nozzle configu-
ration when changing to another
job. Damaged or faulty nozzles
can also be exchanged via menu
function.
