This study focuses on the design and analysis of a specialised mechanical gripper for an assembly process of batteries, with particular emphasis on the study of the associated forces and deformations. The project commences with comprehensive market research to identify existing solutions. This is followed by the definition of requirements and an iterative design process utilising computer-aided design (CAD). Subsequently, a comprehensive force and deformation analysis is conducted using the finite element method (FEM) in Abaqus CAE. The results demonstrate that the designed gripper can withstand the applied loads with minimal deformation, indicating that it possesses adequate structural stiffness. The utility of finite element method (FEM) analysis in evaluating the viability of the proposed design is demonstrated. According to the design and analysis in this study, it manages to propose and developed a new kind of gripper with a higher grip range than those available on the market. These findings contribute to a deeper understanding of the suitability of the gripper design in relation to the expected loads and highlight the importance of the design methodology employed.
