Design And Research Of Programmable Delivery Platform Based On Omnidirectional Wheel

With the diversification and individuation of consumer demand,logistics demand presents the characteristics of small batch,multi-variety and high frequency,so the individualized demand for goods transportation and sorting process is increasing day by day.However,at present,the conveyor belt is generally one-way transmission,only transmission is the main,the function is single,and the goods can only travel according to the existing site layout of the conveyor belt,and different goods can not be transported according to different trajectories.In view of the above problems,this paper proposes a programmable transmission platform based on omnidirectional wheel,which is solved by the joint design of two parts of mechanical and control system.The main research contents of this paper are as follows:Firstly,a programmable conveying platform based on omnidirectional wheel is proposed.The conveying platform adopts modular design,which can flexibly change the layout of the conveying platform according to the needs of the site.The structural design of a single module of the conveying platform is carried out,the omnidirectional wheel roller and hub in its composition are calculated and designed,the gear transmission mechanism in the first transmission mechanism and the synchronous belt transmission mechanism in the second transmission mechanism are calculated and selected,and the upper support panel,the intermediate support panel and the gear transmission mechanism are analyzed by finite element method to ensure the rationality and scientific nature of the structure design of the conveying platform.Secondly,based on the structure design of the conveying platform,the kinematics and dynamics of the conveying platform are analyzed,and the equations of kinematics and dynamics are constructed.By using the ADAMS to simulate the function of conveying and sorting goods of the conveying platform,the displacement curve of the goods under these two different functions is obtained,and the consistency between the structure design of the conveying platform and the kinematics and dynamics analysis is further verified.Then the control system of the conveying platform is designed.By comparing the advantages and disadvantages of centralized control and decentralized control,the decentralized control is determined as the control mode of the control system,and the control chip is introduced.Finally,the physical prototype is built and the program is debugged.The basic tasks of transportation and sorting are completed.The rationality of the structure design and control system design of the conveying platform is verified by practical application.Figure[57]table[7]reference[58]...
