  • Advanced gripper development and tests for automated photovoltaic wafer
           handling
    • Authors: literatinetwork@emeraldinsight.com (Tim Giesen; Erwin Bürk, Christian Fischmann, Wolfgang Gauchel, Manfred Zindl, Alexander Verl)
      Abstract: Abstract

      Purpose – The purpose of this paper is to provide a technical review of a new Bernoulli gripper development using computed fluid dynamics (CFD) modeling, and also to outline an appropriate independent testing method for validating and evaluating process capability in terms of automated thin wafer handling. The investigation has been carried out by a collaborative way of Festo and Fraunhofer IPA as a connecting link between applied research and industrial needs. Design/methodology/approach – Following an introduction, the paper first describes the basic development and fundamental principles of a gripper based on Bernoulli's law. The gripper was dimensioned and designed with the aid of CFD methods. The performance of the hardware was tested using extreme parameter settings while gripping thin, fragile workpieces. The performance of the gripper was tested from the aspects of shortest cycle times, positioning accuracy and air consumption and followed a manufacturer-independent design of experiments. A characterization of the gripping force generated during horizontal and vertical tension tests provides conclusive closed loop validation with regard to the gripper's air flow in the initial CFD model. Findings – Photovoltaic (PV) grippers are challenging components since the handling objects, 200-120?µm thin crystalline silicon wafers with an area of 156×156?mm, are one of the most fragile parts as far as required handling speeds and cycle times are concerned. Originality/value – The paper provides a detailed technical review of a CFD application used in the development of a Bernoulli gripper and also describes a method for testing and evaluating PV grippers for industrial scale applications. The article presents the results of a close cooperation regarding an industrial development (Festo AG & Co. KG) and independent applied research (Fraunhofer IPA) for advanced product benchmarking and validation in a relatively young but dynamic and increasingly-automated PV industry.

  • Synchronisation of a multi-motor speed control system
    • Authors: literatinetwork@emeraldinsight.com (Hassan Kaghazchi; James Mannion)
      Abstract: Abstract

      Purpose – The purpose of this research is to compare an industrial ethernet based network (PROFINET Class 1) with a traditional fieldbus network (PROFIBUS). Design/methodology/approach – Two sets of identical motors were used in the experimental set-up. The speed synchronisation of a lead and follower motors was compared using both PROFINET Class 1 and a PROFIBUS DP network. The level of synchronising achievable was used as a measure of performance for each network. Findings – It was found that PROFIBUS DP produces a better performance for set point and load changes than PROFINET Class 1 network. Research limitations/implications – PROFINET Class 2 and higher could not be used in the experiment due to availability of equipment and funding. Practical implications – This research provides a comparative study of two very popular industrial networks. The results can be used as reference by industry for selection of industrial networks. Originality/value – The paper provides a manufacturer independent practical comparison of two industrial networks. The application area of speed synchronisation is demanding, and should inform the user on the performance and limitation of industrial networks.

  • Mobile monitoring and control framework with active-push and plug-and-play
           capabilities
    • Authors: literatinetwork@emeraldinsight.com (Allen Y. Chang; Yu-Yung Li, Min-Hsiung Hung, Ting-Fan Yen)
      Abstract: Abstract

      Purpose – The purpose of this paper is to describe the development of a novel mobile monitoring and control (MC) framework with active-push and plug-and-play capabilities. This proposed framework is particularly designed to addresses the shortcomings of the traditional factory MC systems in sharing information over the internet, protecting the system security, delivering warning messages, and deploying monitoring points. Design/methodology/approach – By leveraging web service technology, mobile devices, and wireless communication, this paper describes the methodology and approach for designing a MC server, a wireless monitoring module (WMM), an intelligent v-Machine, two active-push mechanisms, a pocket PC application, and a smart phone application. Findings – The designed WMM enables the monitoring points to be deployed in a mobile manner. The proposed mobile MC framework (MMCF) can timely detect abnormalities of appliances and equipment and turn off appliances in dangerous situations through WMM. It can also instantly deliver various warning contents to the mobile devices carried by the responsible persons. The v-Machine is built based on virtual metrology (VM) technology and can predict production precision of machined workpieces. Research limitations/implications – With the successful design and testing of the novel MMCF, this framework can obviously be used for many more applications and developments. Practical implications – The authors' implement a factory MC system based on the proposed framework and conduct various integration tests on two electric appliances and a practical CNC machine tool in a factory. Testing results shows that the factory MC system works smoothly according the design goals and can overcome the shortcomings of traditional factory MC systems. The MC system also presents good performances, instantly delivering warning contents with a size ranging from 1K bytes to 10M bytes to the users within few seconds. Social implications – The proposed MMCF exploits various automation technologies to detect equipment's abnormalities, reduce the rate of product defects caused by human errors, reinforce security, prevent accidents, and ensure the safety of operations. Originality/value – The proposed MMCF can effectively promote existing factory MC systems to achieve the merits of mobile MC, which is a unique contribution of this work, compared to previous studies. The results of this study can be applied to a variety of industrial automation applications, including factory automation and assembly automation.

  • An improved discrete particle swarm optimization algorithm for high-speed
           trains assembly sequence planning
    • Authors: literatinetwork@emeraldinsight.com (Mingyu Li; Bo Wu, Pengxing Yi, Chao Jin, Youmin Hu, Tielin Shi)
      Abstract: Abstract

      Purpose – In the high-speed trains (HSTs) production process, assembly sequence planning (ASP) problems is an extremely core issue. ASP problems influence the economic cost, amount of workers and the working time in the assembly process, seriously. In the design process of HSTs, the assembly sequence is usually given by experience, and the correctness of the assembly sequence is difficult to guarantee by experience and low effectiveness. The ASP based on improved discrete particle swarm optimization (IDPSO) algorithm was proposed to address these issues. Design/methodology/approach – In view of the local convergence problem with basic DPSO in ASP, this paper presents an IDPSO, in which a chosen strategy of global optimal particle is introduced in, to solve the ASP problems in the assembly process of HSTs operation panel. The geometric feasibility, the assembly stability, and the number of assembly orientation changes of the assembly are chosen to be the optimization objective. Furthermore, the influences of the population size, the weight coefficient, and the learning factors to the stability and efficiency of IDPSO algorithm were discussed. Findings – The results show that the IDPSO algorithm can obtain the global optimum efficiently, which is proved to be a more useful method for solving ASP problems than basic DPSO. The IDPSO approach could reduce the working time and economic cost of ASP problems in HSTs significantly. Practical implications – The method may save the economic cost, reduce the amount of workers and save the time in the assembly process of HSTs. And also may change the method of ASP in design and manufacturing process, and make the production process in HSTs more efficiently. Originality/value – A chosen strategy of global optimal particle is presented, which can overcome the local convergence problem with basic DPSO for solving ASP problems.

  • Innovations like two arms, cheaper prices, easier programming, autonomous
           and collaborative operation are driving automation deployment in
           manufacturing and elsewhere
    • Authors: literatinetwork@emeraldinsight.com (Richard Bloss)
      Abstract: Abstract

      Purpose – The purpose of this paper is to discuss how robot innovations as well as educational experiences are driving the more rapid deployment of automation into the manufacturing environment and other applications and reviewing the impact on employment. Design/methodology/approach – In-depth interviews with builders and system integrators of automation equipment and conferring with users of robotics as well as attendance at conferences and trade shows addressing these topics. Findings – Originally robots addressed only “heavy lifting” applications where cost and flexibility were very secondary considerations. Today users are looking to deploy robotic automation into all types of manufacturing and other applications where lower cost, two-armed flexibility and ease of programming are some of the very important considerations. Robotics are making manufacturers more competitive and growing thus creating more jobs, not costing jobs. Practical implications – Customers may be surprised at the automation innovations and new applications which are appearing in the workplace and how easy they are to implement and deploy. Originality/value – A review of and insight into some of the latest automation rapid deployment innovations and applications that have appeared recently as well as demonstrations of automation application at recent trade shows.

  • Integrated product design and assembly planning in an augmented reality
           environment
    • Authors: literatinetwork@emeraldinsight.com (L.X. Ng; Z.B. Wang, S.K. Ong, A.Y.C. Nee)
      Abstract: Abstract

      Purpose – The purpose of this paper is to present a methodology that integrates design and assembly planning in an augmented reality (AR) environment. Intuitive bare-hand interactions (BHIs) and a combination of virtual and real objects are used to perform design and assembly tasks. Ergonomics and other assembly factors are analysed during assembly evaluation. Design/methodology/approach – An AR design and assembly (ARDnA) system has been developed to implement the proposed methodology. For design generation, 3D models are created and combined together like building blocks, taking into account the product assembly in the early design stage. Detailed design can be performed on the components and manual assembly process is simulated to evaluate the assembly design. Findings – A case study of the design and assembly of a toy car is conducted to demonstrate the application of the methodology and system. Research limitations/implications – The system allows the users to consider the assembly of a product when generating the design of the components. BHI allows the users to create and interact with the virtual modes with their hands. Assembly evaluation is more realistic and takes into consideration the ergonomics issues during assembly. Originality/value – The system synthesizes AR, BHI and a CAD software to provide an integrated approach for design and assembly planning, intuitive and realistic interaction with virtual models and holistic assembly evaluation.

  • Locating and clamping of complex geometry workpieces with skewed holes in
           multiple-constraint conditions
    • Authors: literatinetwork@emeraldinsight.com (Branko Tadic; Bojan Bogdanovic, Branislav M. Jeremic, Petar M. Todorovic, Ognjan Luzanin, Igor Budak, Djordje Vukelic)
      Abstract: Abstract

      Purpose – The purpose of this paper is to propose a general model for locating and clamping workpieces of complex geometry with two skewed holes under multiple constraints. Design/methodology/approach – Numerous constraints related to application of the proposed model are discussed as prerequisite to design of fixture solution. Based on theoretical model, a fixture was designed and successfully tested in experimental investigation. Experimental results were also verified using FEM simulations. Findings – This study showed that, opposed to conventional approach, novel solution results in significantly smaller fixture dimensions, while providing greater stability. Insertion of mandrels and supports element sub-assemblies into the workpiece holes significantly increases workpiece stiffness through an increased moment of inertia, while the internal support elements largely diminish the problem of thin wall deformation in the workpiece. Practical implications – The fixture designed in this case was actually used in industrial application to accommodate a thin-walled casting of gearbox housing, where it proved to be a very stable framework. It can be used in industry without any major readjustments. Originality/value – According to available literature, this work is the first successful implementation of a fixture solution in which the problem of multiple constraints is solved by attaching centering elements, support sub-assemblies, and other fixture elements to the internal workpiece walls, and then locating them in the second part of the fixture.
