Description

Technical Field

[0001] This utility model relates to the field of solar cell manufacturing technology, specifically to a glass cleaning device. Background Technology

[0002] Photovoltaic glass is a crucial material in the encapsulation process of solar cell modules. It is formed by melting silicon dioxide and other chemical substances together. During melting, a continuous network structure forms on the surface of the photovoltaic glass, and during cooling, the viscosity gradually increases and it hardens. Because the production of photovoltaic glass is not in a closed environment, the surface of the finished photovoltaic glass may contain adhering dust, crystalline impurities of silicate non-metallic materials, and foreign matter such as broken glass paper. These foreign matter are encapsulated within the solar cell module during the module manufacturing process, causing product defects.

[0003] Therefore, a solution is needed to address the problem of foreign objects being sealed onto the surface of photovoltaic glass during the production of solar cell modules, leading to product defects. Utility Model Content

The device includes: a brush assembly comprising multiple cleaning brush units arranged side-by-side, each cleaning brush unit including cleaning brushes; the height and angle of each cleaning brush relative to the photovoltaic glass to be cleaned are adjustable to clean foreign matter from the surface of the photovoltaic glass; a suction assembly comprising multiple suction units arranged side-by-side, each suction unit including a suction pipe; the height and angle of the suction pipe relative to the photovoltaic glass to be cleaned are adjustable; the suction port of the suction pipe is adapted to face the photovoltaic glass being transported on the production line to extract foreign matter from its surface; and a cleaning frame disposed on the production line, with the brush assembly and the suction assembly installed at intervals along the transport direction of the photovoltaic glass to be cleaned on the cleaning frame.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example refer to Figure 1 and Figure 2 This embodiment provides a glass cleaning device for cleaning foreign objects on the surface of photovoltaic glass on a production line.

[0022] This embodiment provides a glass cleaning device for cleaning foreign objects from the surface of photovoltaic glass 9 to be cleaned on a production line, including: The brush assembly includes multiple cleaning brush units arranged side by side. Each cleaning brush unit includes a cleaning brush 1. The height and angle of each cleaning brush 1 relative to the photovoltaic glass 9 to be cleaned are adjustable. The cleaning brush 1 is suitable for contacting the photovoltaic glass 9 to be cleaned while it is being transported on the production line to clean foreign objects from the surface of the photovoltaic glass 9. The suction assembly includes multiple suction units arranged side by side. The suction unit connected to the brush assembly includes a suction pipe 4. The height and angle of the suction pipe 4 relative to the photovoltaic glass 9 to be cleaned are adjustable. The suction port of the suction pipe 4 is adapted to face the photovoltaic glass 9 to be cleaned being transported on the production line to suck up foreign objects from the surface of the photovoltaic glass 9 to be cleaned. The cleaning frame (not shown in the figure) is set on the production line. The brush assembly and the suction assembly are installed at intervals along the conveying direction of the photovoltaic glass to be cleaned on the cleaning frame.

[0023] The glass cleaning device provided in this embodiment, through the arrangement of a brush assembly and an air suction assembly, uses the air suction assembly to draw air from the surface of the photovoltaic glass to be cleaned on the production line. This, combined with the brush assembly's contact with the photovoltaic glass 9 being transported on the production line, cleans the surface of the photovoltaic glass 9 during transport, removing dust, crystalline impurities of silicate non-metallic materials, and foreign objects such as broken glass paper. Larger objects are swept away by the cleaning brush 1, while smaller ones are absorbed by the suction pipe 4, thus thoroughly cleaning the surface of the photovoltaic glass 9 and preventing foreign objects from being sealed into the solar cell module in subsequent operations. The air suction assembly and brush assembly are spaced apart, and their height and angle relative to the photovoltaic glass 9 are independently adjustable. The height or angle of any one assembly can be adjusted individually, providing greater flexibility. Since the air suction assembly includes multiple air suction units arranged side-by-side, the appropriate number of air suction units can be selected according to the model and size of the photovoltaic glass 9 to be cleaned, adapting to different models and sizes of photovoltaic glass. Similarly, since the brush assembly includes multiple cleaning brush units arranged side by side, the appropriate number of cleaning brush units can be freely selected according to the model and size of the photovoltaic glass to be cleaned, so as to adapt to different models and sizes of photovoltaic glass to be cleaned.

[0024] In this embodiment, the cleaning brush unit includes a brush height adjusting slider 2 and a brush connecting rod 3. The brush height adjusting slider 2 is mounted on the cleaning frame and connected to the cleaning brush 1 via the brush connecting rod 3. The brush height adjusting slider 2 is adapted to move up and down in a direction perpendicular to the plane of travel of the photovoltaic glass to be cleaned. Since the photovoltaic glass to be cleaned is conveyed horizontally on the production line, the brush height adjusting slider 2 can move up and down in a direction perpendicular to the horizontal, thereby driving the brush connecting rod 3 to drag the cleaning brush 1 up and down in a direction perpendicular to the horizontal, thus adjusting the height of the cleaning brush 1.

[0025] In this embodiment, the brush linkage 3 includes a first linkage connected to the brush height adjustment slider 2 and a second linkage connected to the cleaning brush 1. One end of the first linkage is connected to the brush height adjustment slider 2 via a pivot, and the first linkage is adapted to swing freely in a plane perpendicular to the surface of the brush height adjustment slider 2, thereby driving the cleaning brush 1 to swing freely. One end of the second linkage is connected to the cleaning brush 1, and the other end is movably connected to the end of the first linkage away from the brush height adjustment slider. In this way, the swinging of the first linkage drives the second linkage, which in turn drives the cleaning brush 1, thereby adjusting the angle of the cleaning brush 1 relative to the photovoltaic glass to be cleaned.

[0026] In this embodiment, the bristles of the cleaning brush 1 are arranged on the same side of the brush handle. The side of the brush handle opposite to the bristles has a first connector 11 on one side and a first interface 12 on the opposite side. The first connector 11 and the first interface 12 work together to connect adjacent cleaning brushes 1 into a single unit. Figure 2 As shown, the first connector 11 can be, for example, a plug, and the first interface 12 can be, for example, a socket. Adjacent cleaning brushes 1 are connected as a whole through the mating of the plug and the socket. This allows for the selection of an appropriate number of cleaning brushes 1 to be connected together for cleaning, based on the different models and sizes of the photovoltaic glass 9 to be cleaned.

[0027] In this embodiment, the suction assembly includes a suction pipe height adjustment slider 5 and a suction pipe connecting rod 6. The suction pipe height adjustment slider 5 is mounted on the cleaning frame and connected to the suction pipe 4 via the suction pipe connecting rod 6. The suction pipe height adjustment slider 5 is adapted to move up and down in a direction perpendicular to the plane of travel of the photovoltaic glass to be cleaned. Since the photovoltaic glass 9 to be cleaned is conveyed horizontally on the production line, the suction pipe height adjustment slider 5 can move up and down in a direction perpendicular to the horizontal, thereby driving the suction pipe connecting rod 6 to drag the suction pipe 4 up and down in a direction perpendicular to the horizontal, thus adjusting the height of the suction pipe 4 and driving the suction pipe to move up and down.

[0028] In this embodiment, one end of the suction pipe connecting rod 6 is connected to the suction pipe height adjusting slider 5 via a rotating shaft. The suction pipe connecting rod 6 is adapted to swing freely in a plane perpendicular to the surface of the suction pipe height adjusting slider 5, thereby driving the suction pipe 4 to swing freely. The other end of the suction pipe connecting rod 6 is connected to the suction pipe 4. In this way, the height and angle of the suction pipe 4 relative to the photovoltaic glass 9 to be cleaned can be adjusted by swinging the suction pipe connecting rod 6 in a plane perpendicular to the surface of the suction pipe height adjusting slider 5.

[0029] In this embodiment, the air inlet of the air inlet of the air inlet tube 4 has a second connector 41 on one side and a second interface 42 on the opposite side. The second connector 41 and the second interface 42 work together to connect adjacent air inlet tubes 4 into a single unit. Figure 2 As shown, the second connector 41 can be, for example, a plug, and the second interface 42 can be, for example, a socket. Adjacent suction pipes 4 are connected as a single unit through the mating of the plug and the socket. This allows for the selection of an appropriate number of suction pipes 4 to be connected together, based on the different models and sizes of the photovoltaic glass 9 to be cleaned, for the extraction of foreign objects.

[0030] In this embodiment, the intake pipe 4 is internally provided with a filter 7 and a partially protruding receiving portion (the portion below the filter 7 in the figure, not numbered). The filter 7 is located near the opening of the intake pipe 4, and the receiving portion is connected to the pipe away from the intake opening. The receiving portion is adapted to accommodate foreign objects that fall into the pipe when intake stops, and the filter 7 is adapted to prevent the foreign objects from falling out of the intake pipe opening. The foreign objects contained in the receiving portion will be sucked away during the next intake and will not accumulate in the receiving portion.

[0031] In this embodiment, an extension plate 8 is provided on the side of the outer edge of the suction pipe 4 away from the suction pipe height adjustment slider 5, extending forward from the suction port. The extension plate 8 is adapted to contact the photovoltaic glass 9 to be cleaned during the cleaning operation. Furthermore, the extension plate forms an angle of 15°-90° with the photovoltaic glass to be cleaned when in contact with it. The extension plate 8 can assist the cleaning brush 1 in cleaning foreign objects from the surface of the photovoltaic glass 9, and also prevent small foreign objects from flying away from the gap between the suction port and the photovoltaic glass 9.

[0032] The procedure for adjusting a device is as follows: 1. Move the photovoltaic glass 9 to be cleaned to the cleaning device position; 2. Assemble an appropriate number of suction units and brush units according to the size of the photovoltaic glass 9 to be cleaned to achieve the appropriate size (the width extends about 1cm to 2cm beyond the photovoltaic glass to be cleaned on one side). 3. Adjust the angle of the suction pipe relative to the photovoltaic glass 9 to be cleaned to ensure that the outer plate 8 is parallel to the surface of the photovoltaic glass 9 to be cleaned; 4. Adjust the height adjustment slider 5 of the suction pipe to make the front end of the extension plate 8 contact the surface of the photovoltaic glass 9 to be cleaned; 5. Adjust the angle of the cleaning brush 1 relative to the photovoltaic glass 9 to be cleaned so that the cleaning brush 1 is at about 80° to the opposite direction of the conveying direction of the photovoltaic glass 9 to be cleaned. 6. Adjust the height adjustment slider 2 of the brush so that the cleaning brush 1 is slightly bent and subjected to force when it comes into contact with the surface of the photovoltaic glass 9 to be cleaned.

Although embodiments of this application have been described in conjunction with the accompanying drawings, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. However, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
