Assembly of Hybrid Microsystems Using an Assembly System with 3D Optical Sensor

For the assembly of hybrid microsystems a high accuracy in the range of a few micrometers is required. The combination of a parallel robot with an integrated 3D vision sensor uses positioning marks on the objects for object recognition. Within the assembly process, relative positioning accuracies in the submicrometer range have been obtained. Therefore, it is necessary to use a calibration strategy for matching the coordinate system of the 3D vision sensor with the coordinate system of the robot. The construction of the system, the calibration applied and the positioning accuracy achieved by the robot will be discussed.     

Development of Hybrid Assembly Workplaces

In times of shortened innovation cycles, increasing product variation and demands for faster delivery, the flexibility of production systems is crucial for success. Hybrid workplaces, dynamically configurable for both human workers and robots, help to increase the flexibility. The robot kinematics employed, the available sensors, and the grasping conditions involved in the assembly process mainly determine the changeover effort of a workplace. In this paper, different concepts for hybrid workplaces are introduced and compared with respect to investment costs and configuration effort. Concept application and evaluation are illustrated by final assembly of flat screen monitors.

Automated Assembly of Mechatronic Products

The synergetic combination of mechanical engineering, electrical engineering, electronics and information technology enables mechatronic products to offer high levels of flexibility and performance. This interdisciplinary interaction requires changes in product structure and accordingly adapted in production strategies. The approach outlined in this article shows the specific use of the product structure with a view to increasing assembly efficiency. The product is actively integrated in the assembly process by setting up an IT link and making use of its sensor/actuator equipment and software, thus providing support for the production system. This makes it possible to increase the efficiency of automation while at the same time reducing assembly costs.
