How does an automated glue dispenser work?

Adhesive dispensing systems typically consist of three main subsystems serving specific functions: melting, application and curing. Raw adhesive comes in either liquid or solid forms and is added into the melter to heat up into a consistent, flowable glue. This glue is then pumped to the dispenser which positions, meters and applies the glue onto the part. Once applied and the parts are joined, the curing fixture directs UV light at the glue locations to immediately bring them to full strength.
