Robotically Loaded Custom Automated System
THE CHALLENGE
Design a fully automated multi-station rotor assembly machine. The machine must automatically:
Accept machined rotor shells (multiple types and sizes)
Automatically load magnets (multiple types and sizes)
Apply two part epoxy to shell and magnets using positive displacement dispensing system
Provide magnet bonding with individual bonding force feedback and control
Part cure storage and process control
Individual part inspection
Parts must then be placed on a transfer station to be shear tested and magnetized.
THE SOLUTION
The following methods, components and technologies were implemented and integrated to provide a comprehensive solution:
Dual manually loaded magnet part slides
Robotic part handling (magnets and rotor shells)
Automatically loaded magnet holding tooling
Automatic positive displacement glue dispensing on each magnet
Individual part servo controlled bonding axis'
Individual part force feedback bonding axis'
Robotically controlled cure rack
Part Inspection using laser line generator and Cognex Vision System
IMPACT TO THE CUSTOMER
Part rate of 1 part assembled every 50 seconds or less
Parts are automatically assembled
All magnet pressing is verified using individual axis load cell feedback
All parts are 100% inspected and verified
Bad parts are automatically identified
