Also called direct visual monitoring of the monitoring, the monitoring is to use the eye, since the film in the growth process, the color change will be due to the interference phenomenon, we are controlled according to the color change of the film thickness, there are some errors in this way, so it is not very accurate, need to rely on experience.
Electrical control part adopts PLC automatic control, is to enter the pre-designed in the PLC program, the processor main circuit with Kongshi system on the control panel is connected, when you press the switch on the front panel operation, the transmission of information to the central processor, and then by the central control system analysis and issue commands to execute and complete the action by the branch.
Coating machine is a multi-discipline device, which integrates industry today's most advanced mechanical and electrical technology, control technology, electrical automation, IT technology, refrigeration technology, micro-circuitry integrated systems, high-pressure control systems, mechanical technology, processing technology, optical technology optical technology, pneumatic control technology, optical sensor technology, communications technology, vacuum technology, thin film optics and coating technologies.
It can be said coater is a new industry representatives.
Today, coating machines have been widely used, especially film-plated wide variety of film which is applied to the production of various photovoltaic systems and optical instruments, such as digital cameras, digital cameras, binoculars, projectors, energy control, optical communications display technology, interferometer, satellite missile, the semiconductor laser, micro-electromechanical systems, information industry, laser production, various filters, industrial lighting, sensors, architectural glass, automotive, decorations, coins, glasses, etc. etc., coating machine has been in close contact with human life.
