The Design Of 3D Scanning Lifting Platform And The Research Of Control System

Based on the 3D scan,the product modeling,in the field of design,simulation,testing,demonstration,teaching has been widely used,which greatly shorten the product design cycle,cycle detection.For some special products,such as rocket shell,missile shell,plane shell,manned space station,high-speed train capsule shell,and so on.It is an indispensable link to analyze the aerodynamic and surface assembly error,stress deformation,For scanning assembly modeling,which was assembled.The method is not only time-consuming,high quality requirements for operators,but also unstable when long time scanning.According to the requirements of relevant design specifications,our objective is to design a lifting platform of robot 3D scanning,which have fully automatic operation,full scan,massive height,light weight platform,as a scanning equipment product.Firstly,based on the analysis of the currently common form of lifting mechanism,the multistage synchronous drive screw telescopic structure was considered as the suitable structure for our project.Secondly,the structure of the details was also analyzed.The overall structure of the robot was designed in detail,the whole structure was performed.3D modeling.Main stress component was analyzed by static analysis.To verifythe reliability of structural design.Thirdly,the whole robot control system was studied,the robot kinematics model and positioning and tracking strategy was analyzed,and the PID regulation was designed.On this basis,the design of hardware and writing software of control system were completed.Finally,the robot prototype was preproducted.To verify the correctness of the control system,for the prototype,the initial positioning error correction,the odometer and gyroscope error correction were completed.
