Liebherr Robot System for Bin Picking

Bin picking is one of the most challenging industry auto­mation applications. The foundation of this system is the
automatic unload of randomly arranged work pieces out of
dunnage. To date there are very few robot designs that meet
both the sturdiness and cycle time requirements. Liebherr
offers flexible robot systems with which bin picking can be

economically automated. Liebherr has designed and created
robot systems that help automate manufacturing processes
to increase capacity thereby lowering costs. Many tasks can
be solved with the long established tried and tested work
piece handling components from the Liebherr automation
systems area.

Process Description

Unloading the work piece out of dunnage is a complex interaction between a vision system, software and robot. According
to the part spectrum all process-relevant steps need to be synchronized to reach an optimum grip and positioning result.

Requirement

Randomly arranged parts should be
removed from a transport container.

Visual Data Acquisition

and Analysis

A reliable and dynamic 3D object recognition

system visually acquires and analyzes the data.

Liebherr possesses years of experience with automation
systems in the most varied branches and fields of manufac­turing. This produces proficiency in new technology develop­ment. Liebherr robot systems have a reliable and dynamic
3D object identification system based on powerful software

which separates, identifies, and part selection. This robot
system is also designed with a specially-developed gripper
with additional axes for collision-free gripping and removal
of the parts from dunnage.

Object Identification and Selection

Specially designed software segments identify and
select the tool information and technical conditions.

Collision-Free Work Piece Unload

The intelligent gripper has additional axes and enables
collision-free removal of parts from dunnage.

Object Positioning

Lastly, the tools are precisely positioned at the
defined location or in a machine.
