Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of coating rubber rollers, in particular to a cleaning device for photovoltaic coating rubber rollers. Background Art

[0002] Photovoltaic coating technology deposits one or more specific thin films on the surface of silicon wafers. By using the principle of thin film interference, the reflection of light is greatly reduced, thereby enhancing the photoelectric conversion efficiency of solar cells. This film is usually composed of materials such as silicon nitride and silicon dioxide. These materials not only have good anti-reflection performance but also can passivate the surface of the silicon wafer, reducing the surface recombination rate and further improving the battery efficiency.

[0003] The photovoltaic coating rubber roller is a key device used in the production of solar photovoltaic glass. Its function is to coat an anti-reflection film on the glass surface, thereby improving the power generation efficiency of photovoltaic modules. The application of the photovoltaic coating rubber roller in the production of photovoltaic glass is to solve the problems existing in traditional coating processes and improve product performance. Although traditional spraying methods and dipping methods can complete the coating task, they have problems such as poor coating uniformity and low production efficiency. The roll coating method uses a high-precision rubber roller to ensure that the coating solution is evenly coated on the glass surface, forming a stable anti-reflection film layer, thereby significantly improving the light transmittance and photoelectric conversion efficiency of photovoltaic glass.

[0004] After the coating rubber roller is used for a period of time, impurities will adhere to the surface of the rubber roller, affecting the coating. It is necessary to clean the rubber roller. However, common cleaning devices for photovoltaic coating rubber rollers usually directly clean the rubber roller by scraping or wiping. After some impurities dry on the surface of the rubber roller, they adhere very firmly and are difficult to scrape off. In view of this, this application proposes a cleaning device for photovoltaic coating rubber rollers. Content of the Utility Model
