Gluing systems are generally configured as stand alone work cells. They are typically used for assembly where a component is loaded into the cell using a variety of input devices. Dependent on size and shape, the part could be offered up to the robot using a conveyor system, an end changer or a simple manual slide and lock device to 'post' the part into the cell.

The robot would, on receipt of a 'part present' signal, apply a bead of adhesive to the component in a controlled and consistent maner.

The part would then exit the cell and the mating component would be placed in position ontop of the the bead of adhesive, either manually or automatically, dependent on the process requirements.

The robot will manipulate a dispensing head or applicator, which delivers a constant flow of adhesive. Differing types of adhesive will require variations in applicator design and delivery systems.

Critical process requirements would be constant flow rate, feedback from the sealant delivery system and tip velocity control from the robot controller. A combination of feed and flow will produce optimum results. Flowrate feedback will alert the operator when process variables have not been maintained, as this will compromise quality.

The benefits of automation include:

• Improved quality and consistency
• Increased production levels
• Zero material wastage
• No rework or recall
• High reliability
• Insulation from manning issues
