Cost savings with LEONI unracking solutions
The challenge:
In modern production plants it is often necessary to extract parts (body side panels, roofs, hoods and similar parts) that are then delivered in bins for further processing in a fully automated fashion. To this end, industrial robots are mostly used. If the part is not exactly located where expected, the robot cannot continue its operating cycle.
The solution:
- guidance of the robot via an electronic part-calibration system
- 6D calibration of the part position (translation and rotation) by means of laser or infrared sensors integrated within the gripper – direct connection with robot controller via field bus
- automated adjustment of pick position – online
Your benefit:
- cost saving in comparison to conventional mechanical systems
- easy maintenance and ease of use
- robot guidance independent of lighting conditions or part variations
- minimization of training costs for users and maintenance staff
- compact, light, robust and integrated directly into the gripper, the system can be retrofitted to the production line without time-consuming modifications
Correction takes place directly and automatically in the ongoing production process. During setup the correct part position is learned automatically.
Easy to understand – short instruction time and ease of use.
