Nowadays, there is a huge emphasis on the development of devices, technologies and process in the industry. Automation helps with it in the considerable degree, because it tries to solve the development of technique, what is characteristic sign of production, assembly, control and another process realization, what eliminates the human intervention and error rates. Automated assembly process consists of the assembly and handling operations of component connecting to the different units and final products, what is equipped with appropriate devices to eliminate the human intervention. One of the most productive solutions seems to be the deployment and the use of robots and manipulators, which realize the technological, handling and also transporting process. This contribution deals with the systematic steps for the selection of the appropriate sensory equipment used in the gripping robotic end effectors, which are characteristic for the assembly system, placed in our department laboratories.

We present an innovative, inexpensive end-effector, the robot workcell, and the fuel cell components used to demonstrate the automated assembly process of a proton exchange membrane fuel cell stack. The end-effector is capable of handling a variety of fuel cell components including membrane electrode assemblies, bipolar plates and gaskets using vacuum cups mounted on level compensators and connected to a miniature vacuum pump. The end-effector and the fuel cell components are designed with features that allow an accurate component alignment during the assembly process within a tolerance of 0.02 in. and avoiding component overlapping which represents a major cause of overboard gas leaks during the fuel cell operation. The accurate component alignment in the stack is achieved with electrically nonconductive alignment pins permanently mounted on one fuel cell endplate and positioning holes machined on the fuel cell components and on the end-effector. The alignment pins feature a conical tip which eases the engagement between them and the positioning holes. A passive compliance system consisting of two perpendicularly mounted miniature linear blocks and rails allow compensating for the robot's limitations in accuracy and repeatability.

Design for assembly (DFA) has proved its success in manufacturing to face the market challenge. But the assembly process parameters were rarely concerned in the design for assembly. Aimed at this problem, an algorithm for design for automated assembly of circular parts was proposed. This algorithm can help designer to select the optimal process parameters, such as dimension tolerance of mating parts, location precision of assembly device and so on, subject to budgetary constraints. Finally a case is employed to explain the optimal course.

Main Challenge

Purpose Complexity is the main challenge for present and future manufacturers. Assembly complexity heavily affects a product’s final quality in the fully automated assembly system. This paper aims to propose a new method to assess the complexity of modern automated assembly system at the assembly design stage with respect to the characteristics of both manufacturing system and each single component to be mounted. Aiming at validating the predictive model, a regression model is additionally presented to estimate the statistic relationship between the real assembly defect rate and predicted complexity of the fully automated assembly system. Design/methodology/approach The research herein extends the S. N. Samy and H. A. ElMaraghy’s model and seeks to redefine the predictive model using fuzzy evaluation against a fully automated assembly process at the assembly design stages. As the evaluation based on the deterministic scale with accurate crisp number can hardly reflect the uncertainty of the judgement, fuzzy linguistic variables are used to measure the interaction among influence factors. A dependency matrix is proposed to estimate the assembly complexity with respect to the interactions between mechanic design, electric design and process factors and main functions of assembly system. Furthermore, a complexity attributes matrix of single part is presented, to map the relationship between all individual parts to be mounted and three major factors mentioned in the dependency matrix. Findings The new proposed model presents a formal quantification to predict assembly complexity. It clarifies that how the attributes of assembly system and product components complicate the assembly process and in turn influence the manufacturing performance. A center bolt valve in the camshaft of continue variable valve timing is used to demonstrate the application of the developed methodology in this study. Originality/value This paper presents a developed method, which can be used to improve the design solution of assembly concept and optimize the process flow with the least complexity.
