Pad Printing Machine Automation

Servo and PLC automation for pad printing equipment — registration, print-head motion and cycle timing brought under a single, tunable control system.

  • Servo drives
  • Motion control
  • Mitsubishi PLC
  • HMI

The challenge

Pad printing quality depends on the synchronisation of print-head motion, ink transfer and part registration. Where those motions are mechanically linked, every new product format demands mechanical adjustment and the achievable timing resolution is fixed.

Machine context

  • Pad printing machine — servo-driven print head

Our approach

  1. 01Application study of print cycle and registration requirements
  2. 02Servo drive selection and motion profile definition for the print head
  3. 03PLC control of cycle timing, registration and part handling
  4. 04HMI screen for format parameters and job recall
  5. 05Motion tuning and print quality proving on production parts

Outcome

  • Registration held electronically instead of by mechanical adjustment
  • New product formats recalled from stored parameters
  • Repeatable print quality across a production run
  • Reduced changeover time between jobs
