Challenge
0.3 mm-class SMD parts were being picked up by hand and placed into reels
Precision assembly of 0.3 mm-class micro SMD parts such as lead-frame and chip-type devices was being done manually. Automating it required three things at once: aligning parts of 0.3 mm or less automatically and placing them into reel slots, accepting over 20 part geometries on the same equipment, and inspecting the reel taping result and keeping data without human intervention.
Solution
Two cameras split the job: position before the pick, skew after the pick
The AIVE 2.1 flexible feeder scatters and feeds the parts, and the two cameras of RoboEYE dual-camera vision divide the roles to generate coordinates. The resulting coordinates are linked in real time with the X·Y·R data of the IAI precision robot, carrying the flow from pick to reel slot insertion.
- The top camera (Cam1) recognizes the position, orientation and front-face geometry of the fed part.
- The bottom camera (Cam2) checks and corrects the slight skew of 0.03 mm or less that occurs after picking.
- Combining the correction data from both cameras secured an insertion coordinate accuracy of ±0.05 mm.
- The feeder’s top vibrating basket structure applies vibration evenly to fine parts, with frequency adjusted in 1 Hz steps and amplitude in 0.1 mm steps to reduce flipping and overlap.
- Vibration and vision parameters per part are saved as recipes, and production logs and inspection results are backed up automatically.
Results
From feeding to reel taping inspection, no hands touch the parts
- Pick-and-insert coordinate error ±0.05 mm — achieved by combining top- and bottom-camera correction data.
- Work time cut by 70% — compared with the same process done by hand.
- Reel taping defect rate 0.001% or less.
- Multi-variant recipe changeover under 5 minutes, handling over 20 part geometries on the same equipment.
- With automatic calibration, setup time averaged under 5 minutes.
