Description
The 6-Nozzle placement head
operates on the Collect & Place
principle. 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
system 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
This head operates on the Pick
& Place principle. It is suitable for
picking up particularly sophisti-
cated or large components as well
as non-standard models. High-
resolution and intelligent vision
modules ensure that the compo-
nents meet specified tolerances
and that the placement position
is correct.
The sleeve and nozzle are the
heart of the Pick & Place Head.
The sleeve is mounted such that it
is movable in the longitudinal
(Z-axis) and rotational direction
(D-axis). Each of the two axes are
driven by a DC motor and posi-
tioning is done by incremental en-
coder. Due to the high-resolution
glass incremental panel on the
sleeve, the Pick & Place Head has
an outstanding high rotational posi-
tion accuracy. The movement of
rotation is transmitted directly
from the D-axis motor to the driv-
ing plate on the sleeve via frictional
wheel.
Special nozzles and grippers
increase the component range
of SIPLACE CF. They are either
specific for an individual compo-
nent or for a component family
and suitable for the nozzle
changer. The gripper can even
handle easily components without
a surface for vacuum pick-up.
