3D sensors for reliable bin picking

Bin picking, a key technology for Industry 4.0, involves reliably
gripping and removing chaotically arranged or sorted components from a bin
using an industrial robot. This automated process can be run either dynamically
or statically. Depending upon the application, bin picking systems equipped
with sensors that make use of either structured light or laser triangulation, are
recommended.

3D ShapeDrive sensors for static
applications

Camera-based 3D ShapeDrive sensors are the ideal solution for bin
picking applications where the bins are not in motion. The sensors make use of
structured light, i.e., they project several light patterns onto the components
to be measured in the bin. A camera inside the sensor records these light
patterns and digitalises the components as a 3D point cloud. The advantage of
ShapeDrive sensors is their extremely high resolution, which can go all the way
down to 3 µm, making it possible to detect even the finest of structures on
components.

weCat3D profile sensors for
dynamic applications

weCat3D profile sensors are suitable for bin picking applications with
moving bins, for example, on conveyor belts. The sensors scan the components in
the passing bins with their laser beams and generate a three-dimensional height
profile of the content. Thanks to their extremely high performance with up to
12 million measuring points per second, weCat3D profile sensors provide high
resolution point clouds even in dynamic applications.

Simple integration into the bin
picking system

weCat3D profile sensors and ShapeDrive 3D sensors are distinguished by
their multi-connectivity capabilities. The software development kit, which is
available free of charge, or the GigE Vision server module permits simple
integration into the bin picking system. The point clouds can be easily
evaluated with software from third-party suppliers or incorporated into
user-programmed software via the interface to a software module, which is
provided by Wenglor free of charge.

The weCat3D profile sensors and ShapeDrive 3D sensors are available from
Treotham.
