Structure Design And Motion Simulation Analysis Of The Robot For Grasping And Gluing The Automobile Hood

Industrial robots have many advantages such as high production efficiency,high accuracy,and high quality.Using them in the automobile manufacturing industry can not only solve many problems in manual production,but also make the company’s own products more competitive in the automotive industry.force.Although my country’s automobile manufacturing industry has long introduced and applied industrial robots,most of them still lack core technologies and are generally expensive.This also limits the development of my country’s automobile industry.Therefore,taking the road of independent research and development is an urgent task to be completed.In the production process of automobiles,the handling and gluing operations of the automobile hood usually need to be completed in different stations,which makes the production process complicated and the cost cannot be reduced.In order to reduce work links and improve production efficiency,this paper proposes a six-degree-of-freedom industrial robot that can simultaneously grasp,transport and automatically apply glue to the car hood at the same station.First,referring to the research status of industrial robots at home and abroad,combined with design requirements and design principles,determine the overall design plan of the car hood grabbing glue robot,determine the robot’s transmission system design plan,and select the robot’s joints.Carry out the specific structure design of each part of the robot for grabbing glue,use CATIA to build a three-dimensional model of the robot and carry out the overall assembly,and explain the working principle and function of the robot for grabbing glue on the hood of the car.Secondly,the kinematics analysis of the car hood grabbing and coating robot is carried out,the kinematics model of the grabbing and coating robot is established by the D-H method,the forward and inverse kinematics solution of the robot is obtained,and the MATLB is used for verification.The Monte Carlo method is used to analyze the robot’s working space and obtain a reasonable range of robot motion.Finally,through ADAMS,the car hood grabbing and coating robot is used for motion simulation analysis,a virtual prototype model of the robot is established,the robot motion parameters are determined,and the simulation results are obtained to verify the rationality and feasibility of the grabbing and coating robot motion.
