Parametric Design System Research Of Parallel Pick-place Robot

With the adjustment and upgrading of industrial structure in our country,the parallel pick-put robot will gradually replace the artificial operation and be widely used in pick and place operation situation of automatic production line.In order to meet the different requirements of the pick-put working space of,it's necessary to redesign the machine size of parallel pick-put robots.The traditional design methods have a certain technical requirements to designers,and the problems of repetitive design and low efficiency make it difficult to respond to market demand quickly.This paper will develop the the software platform of human-machine interactive dynamic design which is based on the design prototype of the parallel pick-put robots to realize the function of the parametric design of the parallel pick-put robots and improve the efficiency of the product development process.The main research contents are as follows:Develop an interactive parametric design system for parallel pick-put robot based on the modularization idea and divide functional modules including the database module of the product and parts,the parametric module of positive and negative solution,the parametric modeling module and the analysis module of performance,etc.Design the prototype mechanical structure of the parallel pick-put robot in the parametric modeling module.Establish the product of the design system of the parallel pick-put robot and the database of parts.Complete the product family planning of the parallel pick-put robot based on the modularization and the product family design technology and database access technology.Realize the dynamic preview,search and query functions of products and modules which based on database.Study the forward and inverse kinematics of the parallel pick-put robots and design the forward and inverse kinematics solution parameterization manipulator module of the parallel pick-put robot.Realize the parametric design function of positive and negative solutions based on the hybrid programming with MATLAB software and VS2005 software.Complete the seamless connection between the parametric design model and the Pro/ENGINEER software in the database based on the secondary development technology of Pro/ENGINEER software and realize the modeling of parameterized driving for key components model make sure that the machine can automatically assemble according to the predefined constraint relations of each module.
