A case study of 3D simulation for developing automatic assembly line in the phone-camera industry

ABSTRACT

Three-dimensional (3D) simulation is a core technology in virtual manufacturing (VM). It involves both mechanical simulation and discrete event simulation, which are very useful for developing a new product, equipment, or manufacturing system.

This paper introduces a case study of applying 3D simulation technology to the development of an automatic assembly line in a Korean optical factory. This factory produces a lens module that is the part of phone-camera. 3D simulation technology is applied from the early stage of development. In the conceptual design and the initial design phased for individual equipment, 3D mechanical simulation using CATIA® and IGRIP® is conducted. 3D discrete event simulation with QUEST® is implemented on the detailed design of the equipment and of the whole system. The focus of the simulation is to verify the economical feasibility of the new automatic system. As a result, the takt time is reduced to the quarter of the manual system, and the number of workers in a line is reduced from 17 to 1.
