Testing and assembly specialist Kubik Automation from Baienfurt, Germany is putting SICK's part localizer, the PLOC2D robot guidance system to use in its new sCube assembly cell.

The team of experienced industry experts specialize in the development of innovative products and the optimization of production processes for automation technologies. Tailor-made special machines are developed for the automotive, semiconductor, electronics, medical technology, and consumer goods industries.

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

Anyfeeders are ideal for applications involving different parts 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 working together: an intelligent vibration unit combined with a magazine which separates small parts and realigns them, a vision system which localizes the parts, and a robot which picks up the parts and moves them.

In the electronics industry, the anyfeeder is used to assemble parts for Printed Circuit Board (PCB) production. During production, PCB parts are arranged for assembly so that they are all facing the correct way. Having properly arranged parts makes the assembly process more efficient.

In the semiconductor industry, an anyfeeder can be used for quality control on semiconductor chips. If an adhesive strip on a chip is misaligned, the chip will be unusable. Having an accurate vision sensor to see defects is vital to the success of the semiconductor chips.

Teamwork of components is successful

The work sequence for a part localizer follows the interaction of the three components described. 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 localization. It consists of high-quality image processing hardware and is equipped with an extremely high-performance localization algorithm for reliable and fast part localization. What's more, the PLOC2D particularly impresses with its short setup times. It does not require any programming knowledge and can be put into operation straight away following a simple configuration and parameterization process via web browser. Thanks to the EasyTeach method, it can also be tailored to different parts and can be integrated into numerous robot brands and PLCs. In essence, the robot guidance system from SICK brings order to the chaos of part localization.
