Page 10: Overview
The smart gun is designed to dispense one or two materials in multiple directions and into size restrictive areas. The smart gun is controlled by and mounted to a specific robot determined by the customer. The dispense rate and dispense pressure during operation is controlled by controller operator settings.
Page 11 Smart gun subassembly - Detachable subassembly contains serviceable valves and valve needle seat area. Material bleed port - This port allows air to be bled prior to dispensing material from the smart gun. Smart gun basic assembly - The basic assembly does not include the swivel assembly. The smart gun consists of three integrated valves, which controls the flow of material to each directional nozzle.
Page 12: Theory Of Operation
The smart gun was designed and integrated with the swivel to prevent the air lines from becoming wrapped around the smart gun base. The nozzle end is an application specific piece.
