Automated dispensing system with computer E2V

Overview
The vision-guided PROX / PROPlus / PRO Series is Nordson EFD's most advanced automated dispensing system, configured for precision dispensing and streamlined usability. Engineered for accurate fluid placement with EFD syringe barrels and valve systems, it is suited to electronics, life-science and clean-room manufacturing. Systems include DispenseMotion™ software, integrated vision and multiple feedback modes to ensure placement accuracy and repeatability.

Key capabilities

• DispenseMotion™ software fully integrated with a CCD smart vision camera for vision-guided dispensing and fiducial recognition.
• Three feedback methods for height and placement control: contact sensing, optical sensing and non-contact laser height sensing (automatic tip height adjustment).
• Closed-loop encoding and continuous feedback to enhance process control and accuracy.
• On-screen preview and confirmation of dispense paths; streamlined file import and conversion for simplified setup.

Features

• PROPlus: dual linear guide, advanced servomotor and ball-screw actuation; PROX option: contactless linear motor for higher speed and reduced wear.
• Simplified setup and programming via DispenseMotion™.
• On-screen path preview and confirmation.
• Continuous closed-loop feedback for precise placement.
• Streamlined DXF and CAD file import and conversion to accelerate programming.

Benefits

• Industry-leading repeatability and speed (PROPlus: ±0.003 mm; PRO: ±0.004 mm).
• Improved product quality and consistency through precise fluid placement and integrated inspection.
• Easy integration with existing manufacturing lines; compatible with syringe- and valve-based dispense systems.
• Faster operator onboarding, reducing labor costs.
• Higher throughput and reduced production/material/ownership costs.

Vision, inspection and height sensing

• Integrated CCD smart vision supports fiducial recognition and multi-capture imaging for high-resolution offset correction and precise alignment.
• OptiSure™ automated optical inspection (AOI) verifies deposit width, diameter and placement accuracy.
• Laser height sensing options (Laser B and Laser C) detect surface variations and auto-adjust tip height to prevent uneven deposits or damage.
• Laser C (confocal) is recommended for high-precision detection on reflective or translucent surfaces and for detecting very small ledges under 700 μm.

Applications

• Electronics assembly and conformal coating requiring micron-level placement accuracy.
• Medical and life-science device dispensing where cleanliness, precision and repeatability are critical.
• Clean-room manufacturing and other controlled environments; integration with syringe and valve dispensing equipment.
