DISPLACEMENT ANALYSIS OF PANTOGRAPH MECHANISMS WITH SUPERELASTIC HINGES

For handling of a micromachine element and/or its parts, use of a micr omechanical system is suitable, Thus, a pantograph mechanism is made f rom a plastic resin and superelastic hinges simultaneously using a sma ll injection molding machine. The shape memory alloy having an effect of superelasticity is used as superelastic hinges, Therefore it is pos sible for superelastic hinges to have large bending displacements, The input and output displacements of the pantograph mechanism with super elastic hinges are measured and their linear relationship is confirmed . Then a micromechanical system for microbonding by adhesives is const ructed using piezoelectric actuators, the pantograph mechanism and a n eedle, We confirmed that the proposed mechanical system performs well for microbonding by adhesives.
