The invention relates to the technical field of
vacuum coating, and particularly discloses a
control system for a
vacuum coating machine, which comprises a vacuum
stable state analysis module, a gas flow matching analysis module, a
coating environment control analysis module and a
coating parameter control analysis module. Pressure intensity values of monitoring time points in all control time periods are accurately collected through a
capacitive pressure sensor, the average value of the pressure intensity is calculated, the overall level of the
vacuum pressure intensity in the time period can be visually reflected, and basic data are provided for judging whether the vacuum degree is in a proper range or not; an
active monitoring and prevention mechanism is adopted for the
vacuum coating machine, so that the continuity and the stability of
coating production are guaranteed, a scientific basis is provided for
preventive maintenance of the equipment, the service life of the equipment is prolonged, the probability of sudden failure of the equipment is reduced, the reliability, the high efficiency and the intelligent level of the whole vacuum coating production
system are improved, and the production cost is reduced. And the competitiveness of enterprises in the field of coating
processing is improved, the production cost is reduced, and the product quality is improved.
