Custom Automation System

Midwest Engineered Systems designed and built a Robotically Loaded Custom Automated System. Customer’s cycle time decreased to 1 assembled part ever 50 seconds.

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
