One of the author has already proposed and developed the molding pantograph mechanism with large-deflective hinges and links for miniature surface mount system for manufacturing system. The characteristic of the pantograph mechanism is investigated theoretically and experimentally. The aimed final miniature manufacturing system for micro assembling is composed of the pantograph mechanisms and the following positioning-orientation mechanism. In this paper, a new molding 3-DOF(Degrees of freedom) planar positioning-and-orientation mechanism with large-deflective hinges and links is proposed. The mechanism has two function: a transmission function between manufacturing stations and a positioning-orientation function at the manufacturing station. The mechanism with six large-deflective hinges and seven links is made by the small molding injection machine. The used material is PP (Polypropylene). The mechanism has three linear actuators. In the experiments, the singular points of the mechanism is investigated in its working space and compared with the theoretical results. The performance concerning the transmissibility of the proposed new molding 3-DOF planar positioning-orientation mechanism is confirmed.
