A sensing system for measuring parts deformation and a misalignment in flexible parts assembly

유연성 있는 부품의 조립을 위한 부품변형 및 상대오차 측정장치

Flexible parts can be deformed by the contact forces during assembly on the con to rigid parts and thus their successful assembly requires informations about their deformation as well as a misalignment between mating parts. However, because of the nonlinear and complex relationship between parts deformation and assembly reaction forces, it is difficult to acquire all required informations from only the reaction forces during assembly. In this paper, we propose a sensing system consisting of a camera and multiple mirrors for flexible parts assembly. Simulation results show that the system can be effectively used for detecting parts deformation and a misalignment between mating parts.
