Project Overview
Motionwell Automation designed and built a 12-station rotary indexing assembly machine (Project P22068) for BD (Becton Dickinson), one of the world’s largest medical device companies. The machine assembles safety syringes and blood collection tubes at a cycle time of 15 seconds per part.
The project required integration of multiple automation technologies: servo-driven rotary indexing, vibratory bowl feeding, Epson SCARA robotic pick-and-place, and BD-standard vision inspection. All components were designed for ISO Class 7/8 cleanroom operation.
Machine Design
12-Station Rotary Indexing Table
The core of the machine is a precision rotary indexing table with 12 work stations. Each station performs a specific assembly or inspection operation:
- Component loading via vibratory bowl feeders
- Servo-driven assembly with controlled force profiles
- Multi-point vision inspection (dimensional, presence, orientation)
- OK/NG sorting with automated reject handling
- Epson SCARA robot for final pick-and-place
Vision Inspection System
The vision inspection system meets BD’s quality standards with:
- Keyence vision cameras at multiple stations
- Contour recognition for dimensional verification
- Presence and orientation detection
- Automated OK/NG sorting with reject bins
- Full traceability of inspection results
SCARA Robot Integration
An Epson SCARA robot handles high-speed pick-and-place operations at the output station, sorting assembled products by inspection result and loading into packaging trays.
