[Abstract]:The rapid development of science and technology and manufacturing technology research, especially the development of computer technology, communication technology and electronic technology, manufacturing technology, etc. The automation technology level of industrial production is continuously improved. PLC (Programmable Controller), as an automatic equipment specially applied in industrial environment, has the characteristics of anti-interference ability and strong stability. In the field of industrial control, the automation system which integrates all kinds of automation machines and industrial robots with PLC as the core has become an enterprise seeking industrial upgrading, changing production mode and improving efficiency. The goal of reducing production cost is a hot research direction in the field of industrial automation. This paper mainly focuses on the analysis and research of the production and assembly process of the current air conditioning automation production line. This system adopts Siemens PLCS300 as the control core. On the one hand, combined with the characteristics of the production process of the automatic production line of air conditioning, the specific process is introduced. The process analysis and technical feasibility study are carried out, and the solutions to the automation of specific process processes are put forward, such as vacuum testing workstation and palletizing load shifting workstation to realize automatic operation. On the other hand, The hardware design includes the selection of devices, such as PLC model, touch screen, sensor and so on, electric circuit design, such as power system, vacuum pumping subsystem, etc. The circuit hardware design of palletizing and load shifting system and the analysis of its working principle, the enhancement and improvement of system anti-interference ability, the elimination of power interference and the control system are put forward. The software design is based on the development platform of Siemens TIA (Integrated Industrial Automation) technology to program and configure each sub-part of the system with the concept of function modularization. It includes positioning / isolation subsystem, power system, system abnormal alarm system, production line output statistics, automatic equipment linkage system software programming and system hardware configuration, monitoring interface, alarm system, Login interface and other software configuration, the whole system through the PROFIBUS-DP fieldbus communication mode to integrate the various functional modules, to achieve the automatic production line of air conditioning assembly, testing, This project is applied to the control system of the automatic air conditioning production line to realize the real-time monitoring, assembly and testing of the production data of the automatic production line. The assembly process parameters are effectively designed. The system also has the functions of supervisory control and remote control, and can realize the remote transmission of data. The PLC control system used in the design has the characteristics of strong comprehensiveness, high performance-to-price ratio, and so on. Through the comprehensive debugging of this project, the automation of many assembly jobs is realized, and the system design requirements are fulfilled. This paper provides a design idea for the automation and no-man application of other automatic production lines.
