PrecisionSwirl Overview
PrecisionSwirl Capabilities
The PrecisionSwirl orbital dispenser is regulated
through the control assembly. The orbital dispenser is
used to swirl sealant and adhesives in a variety of appli-
cations.
In a basic robotic system, the control assembly serves
as the interface between the robot controller and the
orbital dispenser via an interface cable. Refer to Robot
Interface Cable Assembly on page 52.
The orbital dispenser is operated either manually from
the control assembly or automatically from a robot con-
troller where the orbital dispenser is programmed to
apply material continuously, or at interrupted intervals,
or both. The orbital dispenser can be stopped, started,
and regulated to suit the application, making high quality
swirl patterns that hold form after the material is dis-
pensed.
The orbital dispenser applies a continuous swirled bead
of material directly on components in targeted areas,
such as the hem flanges on car doors, the interior
seams of the chassis, and on the fixed glass openings of
autos.
Bead profile is “pre–shaped” in a uniform pattern of
overlaid circular loops (see F
IG . 2). Bead shape is
affected by nozzle size, material composition, flow rate,
stand off distance, and orbital dispenser motor speed.
The oscillating nozzle on the orbital dispenser can apply
an accurate swirled bead of material on vertical and hor-
izontal planes.
The orbital dispenser is small enough to apply sealant
and adhesives on any type of surface or material, and
can be directed on any programmable path, including: a
series of crevices, creases, or around a maze of straight
lines, sharp angles, contours, curves, corners, and
openings.
The material source for the orbital dispenser is com-
monly supplied via a dual ram pump fluid supply system,
which can be equipped with filters, temperature condi-
tioning, and a fluid supply header.
