Title Design of an Automatic Coating Machine
Abstract
The main content of this paper is the design of an automatic coating machine, including designing heating system, vacuum pumping and air intake system and control system. The paper researches radiation heating process and infrared spectrum matching. The thermal relationship between the heating tile and the film is analyzed here by establishing heating effect model based on heating distance, heating time, temperature and other parameters. The model and control structure are optimized via experiments and improvement of model parameters. The development of automatic coating machine aims to standardize the packaging equipment, to provide complete theoretical analysis and data support for the research as well as development of coating machine, to overcome the defects of current packaging equipment, significantly improving the effect ,the accuracy and stability of packaging process, reducing the cost.
Keywords vacuum coating machine infrared radiation heating
