Explanation of the process flow of PVD vacuum coating machine equipment
All the process data of the PVD vacuum coating machine equipment must be permanently stored in the database file of the industrial computer hard disk of the vacuum coating machine equipment in order to be easy to call or view, analyze and process at any time. The alarm information, process recipes, real-time data, etc. of the vacuum equipment control system of the coating machine are automatically stored. Every time an alarm occurs or resolves, every time a group of data is determined or modified, the corresponding storage record is added or modified immediately.
During the evaporation process of the vacuum coating machine equipment, a set of real-time process parameter records are added every second, including the date and time of occurrence. Such a design is conducive to the comparison of the set parameters and real-time parameters of each batch, and it is easy to quickly find the problems in the coating process. The amount of real-time data collected by the vacuum equipment of the coating machine can be linked with the link of the vacuum coating machine equipment table and trend chart. They are displayed separately with charts and trend curves. This intuitive display is very conducive to observing and grasping the work process. Problems and take immediate action.
A large amount of data of vacuum coating machine equipment mainly comes from the working parameters of the evaporation process, such as vacuum, temperature, rotation speed, aeration amount, evaporation rate, evaporation power, film thickness and so on. To transfer data with each controller, power supply and instrument, serial communication technology is the most commonly used means. However, it is necessary to group or merge all the data in the design to optimize the data package for different periods and groups, and use several interfaces to transmit independently to reliably improve the work transmission efficiency and meet the requirements of the system for larger data transmission.
