Abstract
Provided are methods and systems for dispensing filament adhesive onto a target substrate. A filament adhesive is applied on a target substrate according to a bead application plan, then the applied bead is checked against performance criteria. A second bead application plan is generated, and subsequent filament bead applied according to the second bead application plan.
Claims20
A method of automatically applying a bead of filament adhesive to a target substrate having a substrate topography, comprising:
- receiving, in a processor, digital input defining a bead application plan and performance criteria associated with the substrate topography;
- providing signals, from the processor, causing a dispensing system with a dispense head to dispense a first set of beads of molten core-sheath filament adhesive according to the bead application plan;
- receiving, in the processor, first sensor input associated with dispensed first set of beads of extruded core-sheath filament adhesive;
- analyzing, in the processor, first sensor input in association with the application plan and performance criteria to compute deficiencies associated with the dispensed first set of beads of extruded core-sheath filament adhesive, and creating a second bead application plan to remedy the computed deficiencies;
- and,
- providing signals, from the processor, causing the dispensing system with a dispense head to dispense a second set of beads of extruded core-sheath filament to the target substrate according to the second bead application plan.
