Background

The heat loss of the outer door and window glass is the main part of the energy consumption of the building, and accounts for more than 50 percent of the energy consumption of the building. Research data has shown that the heat transfer at the inner surface of the glass is mainly radiation, accounting for 58%, which means that the loss of heat energy is reduced by changing the properties of the glass, and the most effective method is to inhibit the radiation at the inner surface. The emissivity of ordinary float glass is as high as 0.84, and can be reduced to below 0.1 after a silver-based low-emissivity film is plated. With the development of low-carbon economy, coated low-emissivity glass becomes the mainstream of the architectural glass market.

Because different equipment and different environments have great influence on the performance of the coated glass, the fine adjustment of the product according to the working parameters of the product is carried out according to the current production condition when one coated glass is produced, so that the performance of the produced product meets the requirements of customers. When the film coating line is used for adjusting the sheet, only one piece of glass can be placed in one pot. This results in many targets without glass, and in idle burning, it wastes power and targets. In the prior art, the target position power is manually adjusted, so that the labor is consumed, the control accuracy is poor, and the product quality is poor.

And S13, calculating the distance between the glass and the inlet of the coating chamber according to the transportation time and the transportation speed of the glass.
