Challenge
Every variant change meant changing the feeder hardware
Together with Hyundai Robotics, the target was high-mix, low-volume production handling automotive sensors, housings and terminals on a single piece of equipment. Because a vibratory feeder uses a dedicated jig shaped to the part, every variant change meant swapping the hardware and readjusting it. Feeding small parts quickly and changing variants frequently were hard to satisfy at the same time on the same equipment.
Solution
Vision finds the coordinates, and if it can’t, the feeder re-scatters — robot, vision and feeder in one loop
The AIVE flexible feeder and FlexiBowl scatter the parts on a flat surface, and RoboEYE 2D smart vision computes the pick coordinates and passes them to the Hyundai Robotics HH7. Because vision finds the part instead of a jig aligning it, a variant change is just a recipe swap.
One cycle runs in the following order.
- The robot sends an image trigger signal to vision.
- RoboEYE analyzes the image and computes the pick coordinates.
- If the part is judged unpickable, the feeder is controlled automatically to re-arrange the parts.
- After re-imaging, pickable coordinates are sent to the robot.
- The robot picks the part at those coordinates and moves it to the next process.
Robot, vision and feeder are connected over TCP/IP and digital I/O (Trigger · Done · Retry), checking each other’s status in real time. Because a failed pick is handled by re-arranging rather than by human intervention, the loop is never broken.
Results
Variant changeover came in under 5 minutes, and pick alignment within ±0.2 mm
- Variant changeover time under 5 minutes — for the parts applied in this configuration. Unlike a vibratory feeder, where a jig had to be machined and fitted for each part, the hardware is not touched.
- Pick alignment accuracy ±0.2 mm — for the automotive sensors, housings and terminals in this configuration.
- Pick defect rate 0.1% or less — for the same part family.
- Automotive sensors, housings and terminals were fed on a single piece of equipment without jig changes.
