4. Project Overview
Duct Insulation Attaching Mechanism

5. Project Overview and Targets
Goals:
20% speed improvement
95% fastening success rate
Accommodates 1 and 2 inch Gripnails or Weld Pins
Accommodates various shape, size sheet metal
Manufacture machine

6. Initial Concepts External and internal research done by team
Designed three possible machines
Number of heads
Gripnail vs. Weld Pin
Safety features
Flat surface or Grid surface
Could also redesign and improve existing machine

7. Initial Concepts (Cont.)

8. Research and Experimentation
Fastening Strength
Gripnail impact test
Gripnail and Weld Pin extraction test
Finite Element Analysis
Frame Design
Modal Analysis

9. Final Design

10. Linear Motion and Hopper
Hopper placed top of each actuator
3 moveable heads, 1 stationary head
Move along single ACME screw
Supported by upper and lower rail

11. Frame and Impact Surface
I-beam for the center column
Square tubing for frame structure
FEA analysis showed greater frame
strength with gusset
Raised harden impact surface

12. Actuators Secondary actuator loads Gripnail Magnet holds Gripnail
Lasers

13. Control Panel 8 electronic air solenoids 4 for impact actuator
4 for loading actuator
PLC unit for machine control
Moisture separator

14. Recommendations and Next Steps
