Medical dispensing robot PROX

for medical devicesautonomous

Overview
The vision-guided PROX / PROPlus / PRO Series is Nordson EFD's most advanced automated fluid dispensing system, engineered for precision, simplified usability, and high repeatability. It integrates vision, multiple feedback methods, and specialized DispenseMotion™ software to deliver accurate fluid placement over rough or uneven surfaces and to support complex dispensing tasks.

Key Features

• Vision-guided system with integrated CCD smart vision camera for fiducial recognition and on-screen preview of dispense paths
• Multiple feedback types: contact, optical, and non-contact laser height sensing to maintain accurate tip height and prevent collisions
• Specialized DispenseMotion™ software with streamlined file import/conversion, simplified setup, and programming
• Constant closed-loop feedback and closed-loop encoding for process control
• Optimized for PICO® and Liquidyn® jet valve systems and syringe/valve-based dispensers
• On-screen preview and confirmation of dispense paths and streamlined workflow for operators

Benefits

• Best-in-class repeatability and speed (PROPlus: ±0.003 mm; PRO: ±0.004 mm; PROX: ±0.003 mm)
• Improved product quality, consistency, and yield through precise deposit placement and verification
• Faster throughput with higher product output and reduced production/material/ownership costs
• Easy integration into existing manufacturing operations and a quicker learning curve for operators

Technology & Capabilities

• DispenseMotion™ software for advanced motion and dispense control, path preview, and intuitive programming
• Integrated vision with fiducial recognition and multiple image capture for higher-resolution offset correction
• OptiSure™ automated optical inspection (AOI) integration to measure deposit width, diameter, and placement accuracy
• Laser height sensing options (Laser B and Laser C/confocal) to detect surface variations and automatically adjust tip height; Laser C (confocal) supports detection on reflective or translucent surfaces and small ledges down to under 700 µm
• Support for jetting valves (PICO®, Liquidyn®), syringe barrels, cartridges, and volumetric dispensing systems

PROX / PROPlus / PRO distinctions

• PROX: Contactless linear motor design for faster actuation, fewer moving parts, reduced wear, and improved longevity; suitable for cleanroom and sensitive environments
• PROPlus: Dual linear guide, advanced servomotor, and ball-screw actuation providing the highest dispensing accuracy and best-in-class repeatability (±0.003 mm)
• PRO: High-performance configuration delivering industry-grade repeatability (±0.004 mm) and simplified usability

Applications
The series is suitable for precision dispensing in electronics, life sciences/medical device manufacturing, clean-room environments, and other industries requiring micron-level fluid placement and high process control.
