This paper presents a hybrid approach for facility layout redesign and dynamic job routing. More specifically, based on the source of uncertainty, the facility layout problem is split into two sub-problems and dealt with by two modules: re-layoutand find-route. Genetic algorithm is used where changes may cause a layout redesign of the entire shop, while function blocks are utilised to find the best sequence of robots for the new conditions within the existing layout. The method is verified in a case study of a hypothetic robotic assembly shop.

Today's small parts assembly lines are typically fully manual or fully automated. When human workers and robots, or other mechanical equipment, work together in a hybrid line concept, there is always a sacrifice of flexibility and a high engineering cost, caused by safety and ergonomic requirements. This paper will outline a study performed with the purpose of investigating the requirements posed on industrial robots introduced into otherwise manual assembly lines, while lifting such limitations. Moreover, it presents some results from a research effort where a robot has been developed that meets these requirements, including a discussion on how this robot could be used in future assembly systems that allow for a partial and scalable automation component.

Hydrodynamic bearings (HBs) are prone to initial wear due to contact friction between the bushing and shaft under the condition of insufficient hydrodynamic pressure (IHP). This problem is usually solved by adding a hydrostatic bearing as a secondary bearing. But it increases complication, expense and power consumption by employing external high pressure pumps. In this paper, a HB and a rolling bearing (RB) with a fixed clearance is assembled to form a Journal-Rolling Hybrid Bearing (JRHB). Two regimes characterized by distinct hydrodynamic pressure are expected in this new design. Under the condition of IHP, the rotor is supported by the RB, which protects the HB from direct contact wear. While under the condition of sufficient hydrodynamic pressure (SHP), i.e. under working condition, the rotor is supported by the HB alone. A test rig was designed and fabricated to investigate the stability behavior of the JRHB to demonstrate its feasibility. Clearance circles of the hybrid bearing, shaft orbits, and load sharing of the RB were measured. The experimental results show that the RB plays a protective role under the condition of IHP; and that the hydrodynamic pressure levitates the rotor at high speeds, and consequently the RB no longer shares the load.

Micro-structured and thus functionalized surfaces offer high potentials for new approaches in processing techniques and product design. However, for mass production purposes quite a few challenges regarding the manufacturing of these surfaces have to be overcome. For the fast and economic production of large quantities of structured polymer films the extrusion embossing process is suitable. For embossing microstructures there are special requirements on temperature control because of the double function of the embossing roll. On the one hand the roll is used as an embossing roll with a high surface temperature to improve the embossing accuracy. On the other hand it is used as a cooling roll with a low surface temperature. Only by using variothermal heating systems these contradictory demands on the temperature control can be met. In order to achieve a high quality of the produced micro-structured films an integrative analysis and optimization of the entire process chain is required. This includes the manufacturing of suitable embossing rolls, the development of coating systems and the adaption of the extrusion process. This paper deals with the entire process chain for functionalized, super hydrophobic plastic parts with contact angles up to 165°. Therefore, conelike surface structures, mimicking the structure of lotus leaves, are replicated. Functionalized parts are produced in the injection molding as well as in the extrusion process; however, this paper focuses on the process chain of the extrusion process.

Automated fiber placement(AFP) is being widely used for producing large and complex composite structures, and ultraviolet(UV) curing has been proved as a good alternative to traditional thermal curing as a low-cost and environment-friendly curing method. A new manufacturing method combining AFP and UV in-situ curing was presented in this paper to manufacture glass fiber reinforced composites for large scale composite structures, especially with thick curing depth. A robot-based fiber placement machine integrating UV-LED for the in-situ curing was developed and a flat panel was fabricated with this method. UV transmission characteristic of single composite layer was obtained and preliminary researches about the effects of UV exposure on laminate performance have been conducted. The results showed that laminates fabricated by the in-situ curing process shows better interlaminar properties when the degree of polymerization is about 67.7% for the first cured layer with the incident UV irradiance. Finally, some key issues concerning the process are discussed.

This paper introduces a new robot concept that aims at closing the gap between a manual assembly and a fully automatic assembly. It is intended to be used for handling and assembly of small parts in a highly agile production scenario, which employs both human workers and robots in the same line, with a frequent need for reconfiguration. The development is at a stage where several prototypes leave the research lab and are being tested in pilot applications, with more work required to reach a fully agile assembly scenario. Substantial parts of the remaining research work are done in the FP7 project ROSETTA.

This paper introduces a microrobotic platform to make, manipulate and break individual paper fiber bonds. An individual paper fiber bond is the construction unit of a paper sheet and its properties affect the strength of the entire network of a paper sheet. In one hand, conventional laboratory tests on paper fiber bonds are mainly performed in a hand-sheet level. On the other hand, reported methods for paper fiber bond strength tests in individual bond level are either direct which are manual, laborious and have a low throughput or indirect which require data interpretation. The microrobotic platform presented in this paper performs direct and individual tests on paper fiber bonds. Making, manipulating and breaking individual paper fiber bonds are accomplished successfully demonstrating the first steps towards individual bond strength measurement.

The increasing threats and opportunities, on the global markets, challenge today the company at several levels. The actual Manufacturing Systems becomes dramatic for the survival and prosperity of the organization. Agility, Sustainability and high rate of Re-usability are the main objectives of an “Evolvable Production System”. Task-specific and process-oriented modules with embedded intelligence, together with distributed control based on agent technology are the cornerstones of an EPS. The realization and management of this kind of systems entail an ontological approach due to their implicit complexity. The reference architecture is the key to canalize the underlying holism of an EPS towards an effective instantiation, which exploits the “Emergent Behavior”, the key driver of the Evolvability of a system. The issues related with the application of this view, such as dynamic link between product and system design as well as the management of a module repository, underline the weakness of present business models. Therefore a model for the emplacement of a System that follows the “Evolvable Paradigm” predicament has been produced in order to enable further studies.

Within the paper, application of learning pallets in an assembly system for real-time scheduling problems is presented. A specific fuzzy inference system (controller) is adopted to enable the pallets to learn from their experiences regarding some key metrics. In order to analyze the performance of this system and the learning pallets with a robust mathematical analysis, the similarity of this assembly network to the BCMP networks in closed queuing theory, is underlined. The results prove this resemblance and show the suitability of its algorithm for analyzing such closed networks.

Three-dimensional circuit carriers offer an enormous potential to enhance the functionality and simultaneously miniaturize the overall size of electronic systems. These Molded Interconnect Devices (3D-MID) are manufactured by injection molding and structuring of 3D circuitry. But for the assembly of electronic components (like resistors, capacitors, IC etc.) on MID no standardized and cost-efficient production equipment is available. To overcome this challenge a method to extend the kinematics of SMD (surface mounted device) pick & place machines by automated multi axis workpiece carriers was developed. This manipulator is designed to realize the 3D-assembly of MID in SMD pick & place machines. By the extended kinematics, the placement of electronic components on inclined process areas of MID is enabled. The first result is a prototype, that approves the feasibility of the kinematic concept and the integration of the manipulator into pick & place machines. This article gives at first an overview of the MID technology with its manufacturing processes and innovative applications. The main requirements for assembling 3D-MID are discussed and the developed manipulator is presented. Finally two strategies for the integration of the manipulator into production lines and a comparison of different assembly solutions are described.
