Title: APPARATUS FOR CLEANING A NOZZLE WITH A DISPENSER AND GANTRY FOR MOVING THE NOZZLE
Abstract:
Apparatuses and a method for cleaning a nozzle by removing an accumulation of material from the surface of a nozzle are disclosed. The apparatus includes a dispenser (50) for dispensing a length of wire and a gantry configured to bring the nozzle into contact with the wire. The wire is in a preferred embodiment, a flux core lead free solder wire having an outer portion containing metal and an inner core containing flux. As the wire is brought into contact with the nozzle, the outer portion of the wire melts due to the heat of the liquid flowing from the nozzle, thereby exposing the chemical agent portion of the wire and removing the accumulation of material, such as dross, from the surface of the nozzle.
