For dispensing precisely sized beads
of two component structural adhesives or sealants, the
Program-A-BeadŽ 692 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 servo motor powered
Program-A-BeadŽ 692
meters, mixes and dispenses precisely sized beads of two component adhesives or
sealants for high volume robot or automated structural bonding / sealing
applications.
The flow rate of mixed material from
the Program-A-BeadŽ 692's positive displacement meter is
electronically controlled through all facets of the dispense process. A 0-10V
analogue input signal and PLC robot controller interface can command higher
dispense rates on the straight aways and lower rates on the curves; thus
maximising efficiency while improving product consistency and quality. The
result - a constant bead size regardless of the contour. |
Thorough material mixing is assured
by the end of arm mounted No-Drip®
dispense valve fitted with a No-Flush™
disposable plastic mixer nozzle which eliminates the need to solvent flush the
mixer. An automatic material purge control system ensures the mixer does not
cure up during short periods of inactivity.
