| Based on PLC of YL-235A type a integrates light equipment training system in higher vocational colleges in electromechanical technology skills contest as a one of the major disciplines equipment which,in the skill competition requirements,disciplines in length,which games content more,in the long-term practice teaching,found the unskilled jobs in the game process more game time,take up the technical work,improve and optimize the time,this paper aiming at the non-technical part of the game process was improved,in order to improve its use efficiency.The main contents of this science are as follows:1.Equipment introduction.The basic working process of YL-235A opto-mechatronics equipment is introduced in four parts:mechanical structure,electrical control,software and equipment working process.Respectively introduced the YL-235A type a integrates light training equipment hardware,YL-235A type a opto-mechatronics integration training equipment of electrical control,YL-235A type a integrates light training equipment software needed for the work and use requirement,finally the overall work process and requirements for devices are discussed in details.2.Combined with the preparation and competition requirements of the skills competition in middle and higher vocational colleges,the paper analyzed the defects and analyzed the reasons for the non-technical time consuming part of the plc-based YL-235A opto-electromechanical integration equipment training system.After the defects were put forward,based on the limitations and effectiveness of solving such problems,the author proposed Suggestions on the current solutions to such problems,such as the unfastness of the materials held by the manipulator and the ease of the conveyor belt,and found out the crux.In this paper,the defects of three positions are put forward in the analysis of the defects,which are the mechanical structure defects of the unstable grasp of the manipulator,the defects of the continued execution of the manipulator due to the missing grasp,and the defects of the conveyor belt feeding instability.3.This paper is introduced in three chapters according to the defect content.The first chapter introduces manipulator claw and unstable status quo and the impact of analysis,the main reasons for the problems in view of the problems put forward ideas about the gripper mechanical renovation and then from the working principle of gas began to claw,transformation calculation analysis,the feasibility of gripper transformation,the manipulator claw claw structure into three claw structure,finally design a three jaw manipulator structure model,and use 3d printing technology to complete the physical simulation of the structure model of the three jaw validation process.The second chapter introduces the problem of the program continued execution after the manipulator claw leakage and analyzes the reasons,puts forward the Suggestions of adding force sensor for improvement,and finally forms the theoretical analysis of feasibility based on the analysis of the performance of all aspects of the force sensor,and finally completes the final transformation by writing part of the grab program to simulate and verify the feasibility of the whole process.The third chapter firstly analyzes the problems existing in the stability of the conveyor belt,then analyzes the reasons affecting the stability of the conveyor belt and the existing countermeasures from the working principle of the conveyor belt,and finally puts forward the improvement Suggestions for intelligent dynamic fault detection on this basis for theoretical analysis and demonstration.Finally,the paper content and method of equipment improvement are summarized,and the future development trend is prospected. |
