Fitz-Thors Engineering, Inc. recently completed a project where our team designed and built a robot cell to automate a scoring process for a major tier-1 automotive supplier. An ABB robot holding a razor knife scores the airbag area of the dash so the airbag can deploy unimpeded. A Keyence 2D micrometer optical measurement sensor is used to check if the blade is dull or damaged before each cut and the robot replaces it if needed. Precision machined fixtures are used to position the dash while a robot mounted force feedback module ensures a constant and repeatable cut depth is maintained. A COGNEX checker mounted on the fixture allows for part traceability and SICK sensors help keep the operation safe. Everything is controlled through a custom Siemens HMI interface.
