Description
Technical Field
The utility model relates to the technical field of glass production equipment, in particular to a film coating device.
Background
With the development of clean energy, the application of photovoltaic glass is wider and wider, and the key of photovoltaic power generation is to effectively absorb sunlight to improve the photovoltaic power generation efficiency. At present, the glass for photovoltaic modules has the reflectivity of about 4 percent, the absorptivity of less than 1 percent, the transmittance of visible light generally does not exceed 92 percent, and because the absorptivity of the glass to light is smaller, the space capable of being reduced is limited, so that the method for reducing the reflectivity is the best method for improving the light transmittance. The reflection can be reduced by plating a layer of anti-reflection film on the surface of the photovoltaic glass, and the light transmission effect of the photovoltaic glass is improved.
Based on the optical antireflection principle, the photovoltaic antireflection glass is a product of glass deep processing which is obtained by plating an antireflection film on a glass raw sheet and then curing the glass sheet or forming an antireflection film layer on the surface of the glass sheet by a chemical method. The current methods for coating the glass surface include a pull coating method, a roll coating method, and a tco (transparent Conductive oxide) glass coating method. The lift-draw coating method is not suitable for single-layer coating, the liquid level must be ensured to have no vibration in the process of lift-draw coating, and the substrate rises vertically, at a constant speed and continuously, so that a continuous film layer with uniform thickness is ensured to be formed on the surface of the substrate; if the liquid level vibrates during the lifting process, the film layer will generate stripes and steps, resulting in discontinuity and uneven thickness of the film layer. The TCO glass coating method is suitable for single-layer and double-layer coating, and the product has stable photoelectric performance, high yield and good thermal stability, but the TCO glass coating method has high technical threshold and high equipment investment and subsequent maintenance cost. In consideration of production efficiency, cost input and automation degree, a roller coating type film coating method is mostly adopted to coat a layer of antireflection film on glass.
Most of the types of coating liquids used in the existing roller coating type coating method are alcohol coating liquids, and a peristaltic pump is adopted for adding liquid in roller coating equipment, and the liquid level is unstable due to discontinuity of liquid outlet quantity caused by rotation of a roller of the peristaltic pump; in addition, alcohol liquid is volatile, concentration change of the liquid on the coating roller can be caused by the phenomena, marks and stains appear on the coating roller, color difference can appear on the coated glass, the thickness of a film layer is uneven, and the film layer is easily damaged in the using process, so that the service life of the coated glass is shortened.
In order to eliminate color difference on glass, a method of adding a wiping piece is adopted, the wiping piece is attached to a coating roller, and friction is generated between the wiping piece and the coating roller along with the rotation of the coating roller in the coating process so as to drive the wiping piece to remove residual marks, stains and the like of coating liquid on the coating roller. However, the wiping piece belongs to a consumable product, and the wiping piece needs to be replaced periodically to ensure effective color difference elimination effect, so a fixing device convenient for replacing the wiping piece needs to be arranged; in addition, good fixation of the wiping piece is particularly important, if the wiping piece is not firmly fixed, the wiping piece can run away from the coating roller, and then the wiping piece can be twisted between the two rollers, so that the operation of the coating device is influenced, and the wiping piece cannot continuously wipe the rollers; in addition, the wiping piece is not firmly fixed, and the fixed side of the wiping piece is unevenly stressed, so that the tight fit between the wiping piece and the coating roller is uneven, and marks at certain positions on the coating roller cannot be wiped. Such conditions occurring during the coating process affect the working efficiency and also the quality of the glass.
