For dispensing precisely sized beads of single
component structural adhesives or sealants over 1,000,000 cps viscosity with
ease.
The
Program-A-Bead®
3 is the manufacturer's system of choice. Because of its electric
drive and interface, the dispense rate may be varied to suit the application
requirements.
By increasing or decreasing the drive motor speed (via signals
from the robot / automation controller), you can match the dispense rate to the
applicator tool tip speed. This is essentially useful in making corner beads
consistently sized with straight path beads. The result - a constant bead size
regardless of the contour.
Operation
The
Program-A-Bead®
3 is a solid state controlled. Electrically driven, positive
displacement metering unit. Its servo motor and ball screw drive powers a free
floating positive displacement metering rod that eliminates reload
cavitation.
The divorced design includes power material inlet and
outlet valves (with carbide components for high wear resistance), a lightweight
metering chamber, and "quick service" cylinder configuration.

Consistent Dispense Flow
Rates
By varying the Program-A-Bead® 3 drive motor speed in relation
to the robot tool tip speed, the system dispenses a consistently sized
bead.
Features
- Fully integrated, analogue
control, brushless positioning servo driven system with integral frameless
resolver, high energy, rare earth magnets, exceptional continuous torque
performance, and industrial grade connectors
- Electromagnetic fail safe brake
- PLC programmable controls - 16
bit microprocessor
- Analogue robot interface (in
control panel) and fast response servo drive eliminates lead / lag.

mA
- Max output voltage: 10V / 10mA
- Lightweight positive
displacement metering cylinder with heat treated and ground free floating rod
for maximum abrasion resistance and no reload cavitation
- Quick Service abrasion
resistant seals
Dispense
Valve
An air operated
2200-033
Snuf-Bak™ dispense valve insures a quick start and immediate stop
to material flow thereby placing the bead consistently and exactly. The valve's
internal design insures that material does not string, drip, or run-on from the
nozzle tip. The valve's seal life typically exceeds 300,000 cycles
The dispense valve's nozzle is configured to suit
your application requirements. A broad selection is available with different
lengths and orifices.
Optional Material
Supply
To assure positive priming, it is recommended that
material be supplied to the meter cylinders by pumps. Other options can include
our SeeTherm™ material temperature
conditioning system.
The Bottom
Line
If you are seriously looking at switching to robotic
two component structural bonding, you can't go wrong with the
Program-A-BeadŽ 3.
Most of the key automotive
manufacturers in the US are using this system to build cars and trucks
