German testing and assembly specialist, Kubik Automation GmbH, is putting SICK Automation’s PLOC2D robot guidance system to use in its new sCube assembly cell. The team of experienced industry experts specialises in the development of innovative products and optimisation of production processes for automation technologies. Tailor-made machines are developed for the automotive, electro-mechanics, medical technology and consumer goods sectors.

For manufacturers, the requirements for flexibility in automation solutions are increasing. With the sCube, several different parts can be handled by a single machine without having to change the entire production process.

  The robot guidance system is designed to localise and select parts from a mix of different parts.

So-called ‘anyfeeders’ are ideal for applications involving different parts and where products are changed frequently. They convey and flip small parts without refeeding and without the use of conveyor belts. An anyfeeder is generally made up of three components which work together: an intelligent vibration unit combined with a magazine which separates small parts and realigns them, a vision system which localises the parts, and a robot which picks up the parts and moves them on.

The work sequence follows the interaction of the three components. The PLOC2D robot guidance system from SICK quickly and reliably detects the position of all parts and transmits position data and orientations to the robot control system. Using this information, the robot is able to pick the correctly aligned parts and feed them to the next process. Any parts that are not properly aligned are ignored. Once the properly aligned parts have been removed, the remaining components in the pick zone are mixed up again by a pulsed vertical oscillation from the vibration unit.

The PLOC2D is a vision system for two-dimensional part localisation. It consists of high-quality image processing hardware and is equipped with a high-performance localisation algorithm for reliable and fast part localisation. The PLOC2D also offers the advantage of short setup times. It does not require any programming knowledge and can be put into operation straight away following a simple configuration and parameterisation process via a web browser. The EasyTeach method provides for the system to be tailored to different parts and integrated into different robot brands and PLCs.
