Abstract
A liquid compound dispensing apparatus for dispensing a controlled amount of liquid compound onto a workpiece is described. The apparatus comprises a cartridge system. The cartridge system may accept a liquid compound cartridge containing liquid compound. The apparatus also comprises a plate, having a threaded bore, positioned above the cartridge system that is movable in a first and second direction, at least one plunger attached to the plate at a first end and attached to a piston at a second end. The piston is dimensioned to move within the liquid compound cartridge to displace liquid compound when the plate is moved in the second direction. A driving mechanism moves the plate in the first and the second directions to dispense product and comprises a motor, a threaded rod disposed through the threaded bore of the plate that is driven by a driving belt attached to the motor.
