[Abstract]:With the rise of living standards, the demand for domestic cars is increasing day by day.The traditional single vehicle vehicle painting production line can not meet the current production requirements of automotive painting.In order to adapt to the characteristics of small batch, multi-variety and individualized automobile industry, the major automobile manufacturers increase the investment of capital and technology, improve the production process and improve the production efficiency.In this paper, the key technology of how to realize the collinear production of multi-vehicle on the same platform in the flexible painting production line of passenger car is studied.The key to realize flexible multi-vehicle production is to solve the problem of vehicle chain disturbance caused by multi-vehicle body identification and vehicle switching based on flexible conveying equipment design and robot automatic spraying.Therefore, the main research focus of this paper is as follows: 1, from the aspect of coating transportation equipment design, the paper analyzes the conditions of coating flexibility.In the mechanical aspect, the multi-function design and improvement of the conveying skid are carried out, the different body is fixed by the combination of the front and rear fulcrum, and the choice of the mounting position of the carrier body is prepared for the storage and transmission of the body information.In the electric aspect, the wireless radio frequency technology is studied, the storage and transmission of the car body information in the AVI system are analyzed, and the software design of vehicle and color identification is carried out. From the aspect of robot automatic spraying, the conditions of the flexible painting are analyzed.This paper studies the selection of spraying robot and the spray spray of paint, analyzes the working principle of the robot spraying system and the design of color spray code for the vehicle model, and carries on the overall design of the multi-model spraying software of the robot.The standardized module. 3 of spraying program is established. The fuzzy PID algorithm is introduced to study the intelligent control of the automatic speed regulation system of coating line in view of the disturbance of transportation chain caused by the variety of vehicle type.The automatic speed regulation system model, control strategy selection and controller design.Through the Simulink simulation module of MATLAB, the speed regulating system is simulated and analyzed from the aspects of system response, rated speed change and load disturbance, and the advantages and disadvantages of conventional PID control and fuzzy PID control are compared.The superiority of fuzzy PID control method is verified. In the aspect of software design, the software is designed by using the RSLogix5000 programming software of AB Company, which runs on the conveyor chain of the paint line opposite to the paint line and carries out the data transfer and the color code identification of the vehicle model.By using FactoryTalk View man-machine interface software of AB Company, the spot touch screen and host computer monitoring system are designed to prepare for the field test verification of automatic speed regulation control system.And the industrial field test and debugging problems and solutions are summarized.The results of software simulation and field test show that the designed flexible coating line can realize the flexible coating of many kinds of car body, and its automatic speed control system can solve the problem of the deterioration of the speed control performance of the conveyor belt caused by the multi-vehicle switch.The research results can promote the flexible painting production of passenger cars.
