Developing and Optimising of Handling and Assembly Processes

  • Precision Assembly
    Whether sensors, pacemakers or watch movements: wherever parts have to be assembled very precisely, conventional robots and corresponding peripherals reach their limits. In this area, match is investigating new solutions and strategies to implement reliable and economical precision assembly processes.

  • Handling of Hot-Forged Hybrid Components in the Process of Tailored Forming
    The Collaborative Research Center (CRC) 1153 "Tailored Forming" aims to develop the potential for hybrid solid components based on a novel process chain and to design the necessary manufacturing processes. The aim of subproject C7 within the CRC is to provide functional modules for the shape-variable and at the same time precise handling of components with temperatures of up to 1250 °C, taking into account additional process requirements (e.g. cooling of the components in the gripper). Grippers that simultaneously meet high requirements for workpiece variability, workpiece temperature and positioning accuracy do not exist so far.

  • PhoenixD
    PhoenixD is a broad-based cluster of excellence to redefine the design and manufacture of high-performance optics. The aim is to develop intelligent, compact and adaptive optical systems that enable entirely new functionalities and are also suitable for mass production. The cluster unites disciplines from optical design, simulation and manufacturing. In this project, the match takes on precision assembly tasks and deals more intensively with fully process-integrated component alignment via self-assembly and the development of novel, self-optimizing assembly concepts.

  • Self-Assembly
    This research area is concerned with the development of self-assembling or self-positioning systems. The specific design creates energetic potentials that effect the components and thus pull them to the assembly position. Handling of the individual components is no longer necessary, which enables new applications, such as non-contact assembly.

  • CRC 1368: adhesive-based assembly processes in XHV-adequate atmospheres
    As part of the CRC 1368 "Oxygen-free production", processes in manufacturing, assembly and handling technology are being investigated under the complete technical exclusion of oxygen. The joining technology of adhesive bonding plays an essential role in assembly technology, which is why subproject B04 is concerned with adhesive-based assembly processes in an oxygen-free atmosphere. The physical properties of an adhesive bond, which ultimately determine strength and service life, are influenced by oxygen and water in many adhesive systems. The subproject aims to gain knowledge about the technical properties of bonded joints produced in oxygen-free atmospheres and with deoxidized joining partners.

  • Assembly of photonic integrated circuits
    The research collaboration of the Cluster of Excellence PhoenixD pursues the goal of integrating conventional and complex high-performance optics in intelligent, compact and adaptive optical systems. In this context, PhoenixD is working on miniaturised optical systems in which the components developed by the various interdisciplinary research groups are to be demonstrated. In this context, match is researching novel concepts and processes for the precision assembly of optical systems.

  • Assembly station based on a magnetic levitation system
    Magnetic levitation systems can be used to flexibly combine various production stations. In these systems the workpiece carier (mover) hovers above the stator due to electromagnetic forces. By changing the electric fields, the mover can be positioned in six degrees of freedom. To achieve a cost efficient production of optical components or photonic integrated circuits, PhoenixD is following the approach of implementing an inline production machine based on these levitation transport system. The goal is to use the mover not only for the transport between stations, but also as a functional unit during the stations.Therefor the match investigates and develops an integrated assembly station.

  • Strategies for piezo actuator-assisted disassembly of bolted joints
    The Collaborative Research Center (SFB) 871 "Regeneration of Complex Capital Goods" has been researching the scientific principles of regeneration since 2010, using civil aircraft engines as an example. The motivation is how complex components can be efficiently maintained and repaired in a resource-friendly way. The match focuses on and develops novel strategies for gentle disassembly using the example of bolted joints.

Machine Concepts and System Integration

  • Underactuated handling systems
    Within the field of "underactuated handling systems" assembly systems with fewer actuators than degrees of freedom are being researched. The basic idea is to reduce the design effort and avoid the costs of actuated systems, where each degree of freedom is typically linked to a separate motor. The main topics are the structural synthesis of the orientation mechanism and the control of the highly nonlinear dynamics.

  • Aerodynamic part feeding
    Modern production systems are subject to a variety of requirements. On the one hand, there is high cost pressure, as a result of which a high degree of automation is usually sought, particularly in high-wage countries. On the other hand, production is confronted with an increasing number of variants and greater planning uncertainty due to globalized markets, which necessitates a high degree of flexibility in the operating resources used. Particularly in assembly, which represents a central subarea of production, flexible automation solutions must consequently be developed that enable dynamic adaptation to changed boundary conditions.

Robot aided Assembly and Handling Processes

  • Collaborative Assembly of Human and Machine
    In the process chain, assembly represents the last step of value creation and thus plays an crucial role in the production process of companies. The high cost and time-consuming processes involved in the assembly indicate that there is considerable potential for rationalization, from the planning and preparation of the assembly to the execution of the assembly. In addition, companies are looking for solutions to address problems resulting from an aging workforce and an increasing demand for skilled workers. For this reason, match develops collaborative assembly systems and processes.

  • Robot-assisted cooperative handling and assembly
    The handling and assembly of compliant and large-scale components is an important step in the process chain, especially with regard to fiber composite production. The problems that can occur when handling flexible components are their shape changes, which can lead to an undefined placement position. Furthermore, grasping with conventional grippers is often not possible.

  • Autonomous Mobile Robotics
    In the assembly and manufacturing of large-format products and systems, very large and complex handling and assembly devices are used, which can only be set up and operated at one central production site due to their size and complexity. The finished products and systems have to be disassembled and transported to their destination, where they are reassembled. In the future, autonomous mobile robots will be used to assemble or manufacture these large-format machines directly at their destination. This will involve the cooperation of several different mobile robots in various sizes.

  • TRR 277 Additive Manufacturing in Construction
    While productivity in the manufacturing industry increased linearly in most areas, this value has stagnated in the construction industry for about 50 years. The reason for this is the high manual effort required to create complex formwork elements. The aim of TRR 277 is to avoid this by using additive manufacturing processes. An interdisciplinary approach is being pursued, taking into account planning, production and assembly, in order to provide concrete elements that meet future requirements without formwork and more comple geometries in a way that saves energy and resources.

  • Soft Material Robotic Systems
    In the research area of Soft Material Robotic Systems (SMRS) we deal with robot structures made of soft and flexible materials, which - in contrast to their counterparts made of hard materials such as steel or aluminium - are inherently safe in direct contact with humans. SMRS are for example predestined for use in collaborative assembly systems, where humans and robots move and interact in the same workspace.
