Abstract

The article discusses the design and analysis of a high-performance microgripper with a large displacement amplification ratio, essential for precision engineering and biotechnology applications. The microgripper employs a three-stage amplifier mechanism, including bridge-type and lever-type amplification mechanisms, to achieve an impressive displacement amplification ratio of 45.58 and a wide motion stroke of 683.70 μm. The design incorporates parallelogram mechanisms for parallel gripping, enhancing reliability and ease of use. The research involves multi-objective optimization using response surface methodology and theoretical modeling based on elastic beam theory, validated through finite element simulations and experimental investigations. The results demonstrate the microgripper's capability to handle components of varying sizes, making it a standout solution in the field of microgripping technology.
