ABSTRACT:
A robot arm mounted apparatus for high speed streaming of high viscosity, two-part adhesive onto a workpiece. The apparatus employs a shortened, temperatured-conditioned mixing tube and a compact, end effector package of dispense metering equipment associated directly with the mixing tube on the end of the robot arm, rather than mounted remotely as in prior art systems. In a preferred form a pressurized cylinder, displacement rods and chambers, dispense metering valves and shortened, temperature-conditioned mixing tube are connected to one another directly in serial fashion on the end of the robot arm. The mixing tube is preferably modified with a removable, damage-resistant nozzle designed especially for streaming.
