AI Technical Summary

Technical Problem

Existing robotic dispensing systems face challenges in achieving precise bead shapes and orientations, particularly with non-circular nozzle orifices, co-extrusion of multiple materials, and optimal sensor alignment, due to rigidly attached nozzles and heavy extruder assemblies that complicate path planning and lead to collisions and cable management issues.

Method used

A rotary nozzle dispensing apparatus that allows independent rotation of the nozzle relative to the extruder assembly, featuring advanced flow channel designs and co-extrusion capabilities, integrated sensors, and a controller for precise material application, with adaptable attachments for material treatment and monitoring.

Benefits of technology

Enables precise and uniform material dispensing, improves adaptability, and integrates advanced monitoring and control technologies, addressing limitations of existing systems.

Abstract

A dispensing apparatus (400) includes a nozzle adaptor with a first set of flow channels, each channel of the first set of flow channels configured to separately receive dispensed material from a proximal end of the nozzle adaptor, the channels of the first set of flow channels radially spaced around a central axis at a distal end of the nozzle adaptor, and a rotary nozzle (420) rotationally coupled to the distal end of the nozzle adaptor.
