Automated EoL testing of intelligent actuators

Automated EoL testing of intelligent actuators

Challenge

Task

  • development of an automated, robust and fast  test system for verifying product characteristics  during final production step under consideration of part traceability

Objective

  • development of a new software architecture to ensure robust end-of-line automatization
  • implementation of test configurations, handling a high number of variants and implementation of an automatic error-handling
  • ensure comparability between development and production

Framework

  • very high variety of actuators
  • lack of traceability of tests, actuators and sensors

Solution

I. development of a test bench software:

  • modularly built and individually adaptable test bench control for machines with and without external servo motors – during development, validation and production
  • configuration and variant management from the office:
    • traceability via data bank-based approach
    • user management including rights management
    • quality management via implementing a tool-based approval process

II. consulting for hardware development

Benefits

  • infrastructure for product testing
  • time saving through preparation in the office as well as shortened down time of machines through usage of prepared configurations
  • cycle time optimization in the production considering the overall system
  • development of a tool for automatic and user-supported measurement system analysis (MSA)

Technologies

  • industrial measurement technology (National Instruments)
  • LabVIEW
  • compactRIO (cRIO) & FPGA
  • platform development
  • variant management
  • Bosch Rexroth servo motors
  • Siemens PLC SIMATIC S7
