Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass coating production technology, specifically to an automatic cleaning box device for photovoltaic glass before coating. Background Technology

[0002] Solar photovoltaic (PV) cells are used to directly convert sunlight into electrical energy. Photovoltaic glass, located on the outermost layer of the glass, is directly exposed to sunlight, utilizing its extremely high transmittance (>91.5%) to provide light energy to the cells. Photovoltaic glass coatings can effectively increase the solar transmittance of the glass surface (an increase of >2.0%), thereby improving the conversion efficiency and output power of the photovoltaic cells.

[0003] Photovoltaic glass coating employs a roller coating process, where a coating liquid is applied to the surface of the photovoltaic glass using a PU coating roller. Before coating, the photovoltaic glass undergoes pretreatment by grinding its long and short sides to determine its dimensions. After high-speed grinding, the sides of the photovoltaic glass absorb a large amount of glass powder and other impurities. Existing cleaning technologies struggle to remove these impurities, which then adhere to the coating roller, leaving marks and affecting the coating quality. Utility Model Content

[0023] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figures 1 to 2 As shown, this embodiment provides an automatic cleaning box device for photovoltaic glass before coating, including a box body 3. The box body is fixedly installed at the inlet of the coating machine by a frame and is arranged on both sides of the photovoltaic glass 7. The box body 3 has an opening in the middle near the photovoltaic glass, and the edge of the photovoltaic glass 7 enters the box body 3 through the opening and is transported through the box body 3.

[0026] A positioning plate 4 is fixedly installed above the inlet inside the housing 3. A cleaning device and a drying device are installed sequentially on the positioning plate 4 along the conveying direction.

[0027] In this embodiment, the cleaning device includes a cleaning spray gun 2, which is supplied with a cleaning agent 21. The choice of cleaning agent is not limited during operation; it can be a solvent such as isopropanol, which is necessary for coating. The cleaning agent sprayed from the cleaning spray gun 2 acts downwards on the edge of the photovoltaic glass 7, automatically completing continuous edge cleaning before the photovoltaic glass 7 enters the coating machine.

[0028] With the center of the photovoltaic glass 7 as the inner side and the edge of the photovoltaic glass 7 as the outer side, the cleaning spray gun 2 is tilted outward from top to bottom and pointed towards the edge of the photovoltaic glass 7.

[0029] In this embodiment, the installation angle of the cleaning spray gun 2 is 50°~60° with the photovoltaic glass 7. The installation angle of the cleaning spray gun 2 can be adjusted according to the actual cleaning effect. This design allows the cleaning agent to fly outwards as much as possible after acting on the edge of the photovoltaic glass and fall to the bottom of the housing, avoiding large-area flow onto the photovoltaic glass.

[0030] In this embodiment, the drying device includes a drying spray gun 1, which is connected to compressed air (1~4 kg / cm²) 11. The gas sprayed from the drying spray gun 1 acts downward on the edge of the photovoltaic glass, which can effectively remove impurities and cleaning agent residues that have detached from the edge of the photovoltaic glass during the cleaning process.

[0031] With the center of the photovoltaic glass 7 as the inner side and the edge of the photovoltaic glass 7 as the outer side, the drying spray gun 1 is tilted outward from top to bottom and pointed towards the edge of the photovoltaic glass 7.

[0032] In this embodiment, the installation angle of the drying spray gun 1 is 50°~60° with the photovoltaic glass 7. The installation angle of the drying spray gun 1 can be adjusted according to the actual cleaning effect. This design allows impurities and residual cleaning agent to be directly blown outwards and fall to the bottom of the housing.

[0033] The bottom of the box 3 is also equipped with a liquid return collection mechanism, which includes a liquid return funnel 5 located at the bottom of the box and a liquid return pipe 6 connected to the liquid return funnel 5.

[0034] The working principle of this utility model is as follows:

[0035] During use, the edges of the photovoltaic glass 7 are transferred through the housing 3, first passing through the cleaning spray gun 2 mounted on the positioning plate 4. The cleaning spray gun 2 sprays cleaning agent 21 to continuously clean the edges of the photovoltaic glass 7. Then, compressed air 11 is sprayed from the drying spray gun 1 mounted behind the cleaning spray gun 2 to continuously dry the edges of the photovoltaic glass 7. Furthermore, impurities and cleaning agent 21 residues that have detached from the edges of the photovoltaic glass 7 can be collected through the return funnel 5 and returned to the return pipe 6.

[0036] The above embodiments are only used to illustrate and not limit the technical solutions of this utility model.
