High-Mix Injection-Molded Parts Picked and Placed at a ~2-Second Cycle Time

A 2D robot vision pick-and-place automation applied on a real production line. High-mix plastic injection-molded parts are fed by a flexible feeder, their position and orientation recognized, and picked and placed at a cycle time of about 2 seconds.

Solution

A flexible feeder supplies the parts, and 2D robot vision reads position and orientation and passes them to the robot

High-mix plastic injection-molded parts are fed by a flexible feeder, and AIM Vision recognizes the position and orientation of the fed parts. The recognized coordinates are corrected in real time and passed to the robot, which performs the pick-and-place. Feeding, recognition and transfer are tied into a single flow.

  • Flexible feeder — feeds several kinds of injection-molded parts on the same equipment.
  • 2D robot vision recognition — recognizes the position and orientation of the fed parts.
  • Real-time coordinate correction — corrects the recognized coordinates and passes them to the robot.
  • Robot pick-and-place — picks and places at the received coordinates.

Results

High-mix injection-molded parts handled on a real production line at a ~2-second cycle time

  • Pick-and-place cycle time of about 2 seconds — based on the injection-molded parts shown in the video.
  • Several kinds of plastic injection-molded parts are fed and recognized on the same equipment.
  • Position recognition and orientation recognition are applied together, so parts are picked according to the pose they lie in.
  • Not a demo — a configuration applied as a real production line project.

FAQ

Frequently asked about this case

Can high-mix injection-molded parts be fed by a single piece of equipment?

In this case, several kinds of plastic injection-molded parts are fed by a flexible feeder on the same equipment. AIM Vision recognizes the position and orientation of the fed parts and passes them to the robot.

What cycle time do you get for injection-molded part pick-and-place?

About 2 seconds in this case. It varies with part shape and process configuration, so take it as the figure for the injection-molded parts shown in the video.

Can 2D vision recognize the orientation of injection-molded parts?

In this case, 2D robot vision recognizes the position and orientation of the part together. The recognized coordinates are corrected in real time and passed to the robot.

Was this applied on a real production line?

Yes, it is a real production line project. The customer's name is not disclosed.
