| With the proposal of the "Made in China 2025" action program,under the wave of transformation from Made in China to Created in China,domestic steel enterprises are also constantly upgrading and transforming,and the requirements for steel marking equipment are also constantly changing to intelligent and unmanned.development in the direction of localization and localization.After years of development,although domestic steel marking equipment has achieved certain achievements in motion control and marking effect,it is still difficult to adapt to the complex steel marking environment.In response to this situation,this paper developed a set of steel marking equipment based on industrial robots,PLC as the control core,and marking laser as the marking module,which effectively solved the current problems of poor flexibility and unsatisfactory marking effects.,the main research contents of this paper are as follows:1.On the basis of years of research on steel marking equipment by the research group,combined with the on-site production environment and technical requirements,a new steel marking control system scheme is proposed.In order to realize the research on the control system of the marking equipment,the selection and design calculation of the 3D profiler,marking laser,robot,hydraulic system and painting system of the marking equipment are carried out.2.Combined with the requirements of the control system,take PLC as the core to carry out systematic research on the motion module and the identification module of the identification control system respectively,and further details the design of the control system of the robot and the hydraulic system,the data transmission of the identification laser and the automatic focusing function.It shows that the coating properties of the spray paint system and the parameters affecting the thickness of the paint film are studied,and the collaborative operation between each module is realized,which improves the marking effect.3.A detailed study of the communication methods and communication principles between the various parts of the marking equipment,and combined with the problems and needs encountered in the actual use process,the realization of real-time data between PLC and marking lasers,robots,and manufacturers has been formulated.technical solutions for transmission.4.Aiming at the problem that the robot’s marking path is too complicated when the steel is piled up in disorder,the marking time is too long,a solution to the shortest path planning of the robot using the ant colony algorithm is proposed.The MATLAB program is used to simulate the model to be solved,and the optimal parameters to solve the model are obtained.Different methods are used for path planning of the model to be solved,and the motion simulation verification is carried out with Robot Studio software.The simulation results show that using ant colony algorithm for robot path planning can effectively simplify the robot motion path and shorten the marking time. |
