Research And Development Of Automatic Handling Manipulator For Rice Cooker Aluminum Cover Stamping

With the transformation and upgrading of the industry,companies compete to use automation equipment to accelerate the pace of machine substitution.The traditional plant operation and manual loading and unloading methods seriously restrict the development of enterprises.With the gradual implementation of “Made in China 2025” strategies,the stamping production line is moving towards an intelligent direction.This paper aims at solving the problem of manual loading and unloading faced by small and medium-sized small household electrical appliance enterprises in Zhanjiang,and transforming the production line of rice cooker aluminum cover stamping process to solve the problem of high labor cost,low efficiency and high labor intensity.According to the actual production situation of the enterprise,a handling manipulator was designed to assist in processing the loading and unloading process of the aluminum cover the rice cooker.The main contents of this study are as follows:(1)Understand the layout of the workshop production line,analyze the stamping process of the rice cooker aluminum cover and the process flow of the handling manipulator and the main technical indicators of the handling manipulator,and determine the overall plan of the press line and the overall layout of the site.(2)In order to improve the problem of high requirements and poor synchronism of existing robots,a multi-station special manipulator is designed to shorten the loading and unloading time and improve production efficiency.The structural design of the handling robot body is carried out.The key structural components such as the crank slider mechanism and the reducer were designed,and the selection and calculation of the main components were completed.Static analysis of key components based on 3D modeling of the handling robot.(3)According to the production process and production cycle of the handling robot,the input and output of the PLC are distributed,and external wiring of the PLC is designed.At the same time,various working modes are intended for the control system according to the working requirements and the man-machine interface is designed.(4)The production of the dealing with robot prototype was completed,and the performance index of the handling robot was tested,which was able to achieve a production cycle of 15 times per minute.The results showed that the robot met the production requirements.(5)Designed special rice cooker aluminum cover stamping automatic production line,compared with the manual production line and the universal production line composed of multiple robots,the synchronization is better,the efficiency is higher,and the enterprise cost is lower.The automatic conveying production line designed in this study can efficiently complete the workpiece loading and unloading,and the control is simple,which reduces the labor cost of the enterprise,reduces the labor intensity of the workers,and ensures the stable production of products.The application of the research results of this thesis makes a reference value for the realization of automated production lines for large and small home appliance manufacturers.
