Abstract


Manipulator used for injection molding machine is the mechanical equipment specially equipped for molding production automation. With it we can greatly improve the quality of injection molding products and production efficiency. Meanwhile it also can avoid the loss due to human caused by the operating mistakes. For our small and medium-sized injection enterprises, seek a robot which is low cost, simple structure, small volume, easy operation, high economic benefit of the competitiveness become the necessary means of improving competition. Based on this kind of circumstance, design and develop the robots will become our focus. This topic with the special manipulator of 180T-350T injection molding machine for research object, the main research works as follows:Designed the 5-axis servo manipulator structure access to relevant manuals and according to the specific requirements. Adopte the Top-Down design concept in Pro/E for avoid interference occurs between every components. It is not only effective master design intent, but also make organization structure more clear. In order to validate the design of manipulator can satisfy the completed trajectory requirements, import simplified model in Pro/E with constraints and sports vice to ADAMS through the seamless connection interface between Pro/E and ADAMS. Definit constraint condition and drive then get the manipulator verified movement simulation curve and the rationality of the design of verified.In order to ensure the accuracy of manipulator transmission key components must have enough rigidity requirements. Through the finite element analysis of cantiever and beams, we can get their maximum displacement, which validated design also satisfy the rigidity requirements. In order to avoid resonance phenomenon, we get the modal analysis of manipulator key parts, cantilever, and on the basis of which get the frequency domain and time domain analysis.In order to reduce the weight of the manipulator, the beam components were optimized based on the requirements of the displacement with manual as constraint conditions. In the optimization analysis, considered the deformation of all the components of beams so the optimization design more tally with the actual situation. We can get the optimal structure which provides reliable scientific parameters for its localization, intellectual property autonomization.
