Research On Virtual Assembly System Of Mobile Four-coordinate Robot

Traditional production methods of mobile robots often result in inappropriate assembly relationship between parts,mismatched assembly dimensions,incorrect assembly sequence and other problems,which not only causes great economic losses,but also prolongs the production cycle.With the intensification of global market competition and the gradual improvement of product renewal speed,in industrial production,users gradually have higher requirements on product cost,cycle and so on.Enterprises have been constantly exploring the most advanced design methods that can reduce product design time and cost at the same time.In view of the problems in the current industrial production,such as the long research and the waste of raw materials caused by the unreasonable assembly relationship,and the problem which in staff training of enterprises.The project of "research on virtual assembly system of mobile four-coordinate robot" is put forward in this thesis.Virtual assembly technology is one of the important links of virtual manufacturing technology.In this thesis,the mobile four-coordinate robot is taken as the research object,and the virtual assembly technology is used as the basis.This study about the virtual assembly system of the robot model was carried out in EON Studio.The main research contents are as follows:(1)According to the requirements of system design,the overall process and main structure of the virtual assembly system were designed.UG was chosen to buil three-dimensional model.EON Studio was the main virtual assembly development software,and Visual Basic was the system integration programming software.(2)According to the design requirements of mobile four-coordinate robot,the overall structure of mobile four-coordinate robot was designed by analyzing the existing robot structures,and the three-dimensional model.The simulation was completed in UG.(3)Through the study of functional nodes and their functions in EON Studio,the main part of virtual assembly system was completed in EON Studio,including automatic disassembly,manual disassembly and collision detection of mobile four-coordinate robot.(4)Through the EON x control,the communication relationship between EON and VB was established.The modules which was completed in EON are imported into VB.The login interface of the whole system and the main interface of disassembly and assembly are set up in VB.(5)Manual assembly of robot parts by virtual hands is realized through the use of data gloves and position tracker.And the immersion of virtual assembly system is improved: According to the communication principle of 5DT data glove and the movement principle of grasping objects by hand,the 3D model of virtual hand was established.The communication relationship between the data glove and the virtual hand model was established by studying the object grasping principle of the virtual hand.With the help of position tracker,some movements have been realized to grasp the object by the virtual hand.The virtual assembly of some parts of the robot was realized by tracking and positioning the position of the data glove.In this thesis,the mobile four-coordinate robot is taken as the research object,UG as the main modeling software,EON Studio as the main development software.Through the assistance of virtual hand and position tracker,the virtual assembly system of mobile four-coordinate robot is studied and designed.
