Photovoltaics utilizes the photovoltaic effect to generate electricity by projecting sunlight onto silicon materials. The photovoltaic industry mainly includes the production of high-purity polycrystalline silicon raw materials, solar cell production, solar cell module production, and the manufacturing of related production equipment.

[0003] To improve light energy absorption, photovoltaic glass is mostly made of large sheets of coated glass, which requires high flatness of the coating and a low level of foreign matter and dust.

[0004] In existing technologies, due to factors such as workshop environment and the condition of incoming membrane materials, a lot of dust settles between the membrane layer and the glass after lamination, requiring rework or causing defects, such as CN221717839U. Utility Model Content

[0005] One of the technical problems this application aims to solve is that during the photovoltaic glass coating process, there is a significant amount of dust accumulation between the glass and the film layer.

[0006] To address the aforementioned technical problems, this application provides a glass coating apparatus.

[0008] In some embodiments, the height of the dust-adhesive structure in the vertical direction is higher than that of the conveying assembly. The dust-adhesive structure includes a dust-adhesive roller shaft and a force-applying roller shaft. Both the dust-adhesive roller shaft and the force-applying roller shaft are rotatably connected to the frame assembly. The height of the dust-adhesive roller shaft in the vertical direction is higher than that of the force-applying roller shaft in the vertical direction. The film body is located between the force-applying roller shaft and the dust-adhesive roller shaft.

[0009] In some embodiments, the dust-sticking roller shaft includes a rotating part and a dust-sticking part, with the dust-sticking part sleeved on the outside of the rotating part.

[0010] In some embodiments, the dust-adhesive portion includes a plurality of portions, which are sequentially sleeved on the outer side of the rotating portion.

[0011] In some embodiments, the dust-sticking roller shaft further includes a limiting portion, which is movably connected to the rotating portion and is located at both ends of the dust-sticking portion.

[0012] In some embodiments, the glass coating apparatus further includes an air outlet assembly, which includes an ion fan and an air outlet structure. The air outlet structure is connected to the ion fan and is disposed toward the conveying assembly.

[0013] In some embodiments, the first end of the air outlet structure passes through the frame assembly and is connected to the ion fan, the second end of the air outlet structure is connected to the frame assembly, and the air outlet structure has a plurality of air outlet holes, which are spaced apart along the first end to the second end of the air outlet structure.

[0014] In some embodiments, the glass coating apparatus further includes a cutting assembly connected to the frame assembly and located on the side of the first coating structure away from the feeding end of the conveying assembly.

As the conveying assembly operates, the glass and the film move together, achieving continuous and unobstructed rapid coating. Because the dust-adhesive structure is located at the front end of the first coating structure, dust on the film surface and lint from the film edges adhere to the surface of the dust-adhesive structure and will not fall onto the glass, reducing surface contamination. The technical solution of this application effectively solves the problem of excessive dust accumulation between the glass and the film layer in the prior art during the photovoltaic glass coating process.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0032] like Figures 1 to 4 As shown, the glass coating apparatus disclosed in Embodiment 1 of this application includes: a frame assembly 10, a conveying assembly 20, and a coating assembly 30. The conveying assembly 20 is connected to the frame assembly 10. The glass to be coated is placed on the conveying assembly 20. The coating assembly 30 includes a first coating structure 31 and a dust-adhesive structure 32. The film passes sequentially through the dust-adhesive structure 32 and the first coating structure 31. The dust-adhesive structure 32 is rotatably connected to the frame assembly 10. The film is adhered to the dust-adhesive structure 32. The first coating structure 31 is connected to the frame assembly 10. The film is located between the first coating structure 31 and the conveying assembly 20.

[0033] Using the technical solution of Embodiment 1, the glass to be coated is placed on the conveying assembly 20, and the film is adhered to the glass by the first coating structure 31. As the conveying assembly 20 operates, the glass and the film move together, achieving continuous and unobstructed rapid coating. Since the dust-adhesive structure 32 is located at the front end of the first coating structure 31, dust on the film surface and lint from the film edges are adhered to the surface of the dust-adhesive structure 32 and will not fall onto the glass, reducing surface contamination. The technical solution of Embodiment 1 effectively solves the problem of excessive dust accumulation between the glass and the film layer during the photovoltaic glass coating process in the prior art.

[0034] like Figures 1 to 4 As shown, in the technical solution of Embodiment 1, the height of the dust-adhesive structure 32 in the vertical direction is higher than that of the conveying assembly 20. The dust-adhesive structure 32 includes a dust-adhesive roller shaft 321 and a force-applying roller shaft 322. Both the dust-adhesive roller shaft 321 and the force-applying roller shaft 322 are rotatably connected to the frame assembly 10. The height of the dust-adhesive roller shaft 321 in the vertical direction is higher than that of the force-applying roller shaft 322 in the vertical direction. The film is located between the force-applying roller shaft 322 and the dust-adhesive roller shaft 321. The dust-adhesive structure 32 removes dust from the film set above the glass, preventing dust and lint from the surface of the film from falling onto the glass surface and affecting the quality of the coated product. The dust-adhesive structure 32 ensures that the film adheres to the surface of the dust-adhesive roller shaft 321 when passing through the dust-adhesive structure 32, ensuring that dust and lint on the surface of the film are completely removed, reducing the residue of dust and lint. Both the dust-adhesive roller shaft 321 and the force-applying roller shaft 322 are rotatably connected to the frame assembly 10. As the membrane moves with the conveying assembly 20, the dust-adhesive roller shaft 321 and the force-applying roller shaft 322 rotate synchronously, reducing friction between the membrane and the dust-adhesive structure 32, reducing the resistance experienced by the membrane, and preventing membrane deformation. In the technical solution of Embodiment 1, the frame assembly 10 has a fixed shaft for mounting the membrane roller. After the membrane roller is mounted on the fixed shaft, the membrane is continuously pulled out as the conveying assembly 20 operates. The membrane passes between the dust-adhesive roller 321 and the force-applying roller 322 to complete dust removal. Then, it passes under the first coating structure 31 and is adhered to the glass surface. The first coating structure 31 applies a downward force to the membrane, adhering it to the glass surface and expelling as much air as possible between the membrane and the glass to avoid air bubbles on the glass surface after lamination, which would affect product quality. The membrane is tensioned on the above structure, and the membrane has a certain amount of tension, which effectively avoids wrinkles in the membrane during the lamination process, which would lead to poor product quality.

[0035] like Figures 1 to 3As shown, in the technical solution of Embodiment 1, the dust-adhesive roller 321 includes a rotating part 3211 and a dust-adhesive part 3212, with the dust-adhesive part 3212 sleeved on the outside of the rotating part 3211. When a large amount of dust, edge lint, etc., adheres to the outer layer of the dust-adhesive part 3212, the stickiness of the dust-adhesive part 3212 decreases, requiring timely replacement of the dust-adhesive part 3212 to avoid the problem of dust, lint, etc., being unable to be removed from the film later.

[0036] like Figures 1 to 3 As shown, in the technical solution of Embodiment 1, the adhesive parts 3212 include multiple parts, which are sequentially sleeved on the outside of the rotating part 3211. One surface of the adhesive part 3212 is adhesive, and the other surface of the adhesive part 3212 is covered with a release film. The release film prevents the multiple adhesive parts 3212 from sticking together and being difficult to separate. When there is a lot of dust on the outermost adhesive part 3212, the outermost adhesive part 3212 can be peeled off. This operation is convenient and can be performed simultaneously with the film coating, without affecting production efficiency. The outer surface of the force roller 322 has a rubber layer with a certain deformation. The rubber layer adheres the film to the sticky roller 321 by elastic force. When part of the sticky part 3212 is torn off, the diameter of the sticky roller 321 becomes smaller. The rubber roller restores a certain deformation but is still in a deformed state. There is no problem that the film cannot be adhered to the sticky part 3212 due to the smaller diameter of the sticky roller 321.

[0037] like Figures 1 to 3 As shown, in the technical solution of Embodiment 1, the sticky roller shaft 321 further includes a limiting part 3213, which is movably connected to the rotating part 3211. The limiting part 3213 is located at both ends of the sticky part 3212. The sticky part 3212 also includes a roller, with multiple layers of sticky parts 3212 adhered to the outside of the roller. The roller is sleeved on the outside of the rotating part 3211. When the multiple layers of sticky parts 3212 no longer meet the usage requirements, only the roller with the sticky parts 3212 adhered to needs to be replaced. The rotating part 3211 does not need to be replaced, reducing the difficulty of operation. Two limiting parts 3213 are included, located at opposite ends of the dust-adhesive part 3212. These limiting parts 3213 limit the dust-adhesive part 3212, preventing it from moving along the axis of the rotating part 3211, which would cause misalignment between the dust-adhesive part 3212 and the membrane, resulting in incomplete removal of dust and other contaminants from the membrane surface. Threaded holes are provided on the side walls of the limiting parts 3213. Bolts pass through these holes and abut against the outer wall of the rotating part 3211, thus fixing the position of the limiting parts 3213. Loosening the bolts allows the limiting parts 3213 to move along the axis of the rotating part 3211. By changing the positions and distance between the two limiting parts 3213, they can limit dust-adhesive parts 3212 of different sizes, thus increasing versatility.

[0038] like Figure 1 and Figure 4 As shown, in the technical solution of Embodiment 1, the glass coating device further includes an air outlet assembly 40, which includes an ion fan 41 and an air outlet structure 42. The air outlet structure 42 is connected to the ion fan 41 and is positioned towards the conveying assembly 20. The ion fan 41 can generate a large amount of airflow carrying positive and negative charges, which can neutralize the charge on the object. When the object surface carries a negative charge, it will attract positive charges in the airflow; when the object surface carries a positive charge, it will attract negative charges in the airflow. When equal amounts of positive and negative charges come into contact, electrical neutralization can be achieved. The ionized air generated by the ion fan 41 is introduced into the air outlet structure 42, and the air outlet structure 42 exhausts air towards the glass surface. The static electricity on the glass surface is neutralized, avoiding the problem of fine dust adsorbed due to static electricity, and at the same time, it can dry the residual liquid on the glass surface.

[0039] like Figure 1 and Figure 4 As shown, in the technical solution of Embodiment 1, the first end of the air outlet structure 42 penetrates through the frame assembly 10 and is connected to the ion fan 41. The second end of the air outlet structure 42 is connected to the frame assembly 10. The air outlet structure 42 has multiple air outlet holes, which are spaced apart along the first end to the second end of the air outlet structure 42. The arrangement of multiple air outlet holes ensures that the entire air outlet structure 42 can simultaneously blow air to multiple points on the glass, improving the electrostatic removal efficiency. The vertical projection width of the air outlet structure 42 is greater than the vertical projection width of the glass, ensuring that the electrostatic removal at various points on the glass is relatively complete.

[0040] like Figure 1 As shown, in the technical solution of Embodiment 1, the coating assembly 30 further includes a second coating structure. The second coating structure is disposed below the conveying assembly 20 and coats the lower surface of the glass. The second coating structure is disposed opposite to the first coating structure 31, and the two move synchronously to press the glass together, so as to achieve simultaneous coating of the upper and lower surfaces of the glass, resulting in higher coating efficiency.

[0041] like Figure 1 and Figure 4 As shown, in the technical solution of Embodiment 1, the glass coating device further includes a film-cutting assembly 50, which is connected to the frame assembly 10 and located on the side of the first coating structure 31 away from the feeding end of the conveying assembly 20. Multiple pieces of glass to be coated are sequentially placed on the conveying assembly 20 and conveyed by the conveying assembly 20 to the first coating structure 31 for coating. Once one piece of glass has completely passed through the first coating structure 31, the coating is complete. The film-cutting assembly 50 cuts the film, separating it so that the film and the glass correspond one-to-one, facilitating subsequent processing.

[0042] like Figure 1 and Figure 4 As shown, in the technical solution of Embodiment 1, the film cutting assembly 50 includes a vertical drive structure 51, a mounting base structure 52, and a cutting blade structure 53. The vertical drive structure 51 is connected to the frame assembly 10, the mounting base structure 52 is connected to the output end of the vertical drive structure 51, and the cutting blade structure 53 is connected to the mounting base structure 52. The vertical drive structure 51 uses an electric slide rail module, and the mounting base structure 52 is fixed to the output end of the vertical drive structure 51. The mounting base structure 52 moves in the vertical direction, driving the cutting blade structure 53 to move in the vertical direction. The cutting blade structure 53 has a cutting state close to the film and a waiting state away from the film. The electric slide rail module is selected, and its periodic operation is controlled by a program. The movement cycle is calculated according to the conveying speed of the conveying assembly 20 to ensure that the cutting blade structure 53 separates the film from each piece of coated glass. The entire device operates continuously and without obstruction, resulting in high production efficiency.

[0043] like Figure 1 and Figure 4 As shown, in the technical solution of Embodiment 1, the conveying assembly 20 includes multiple conveying roller structures 21, which are rotatably connected to the frame assembly 10. The multiple conveying roller structures 21 are arranged at intervals, and the vertical projection of the cutter structure 53 is located between the vertical projections of two adjacent conveying roller structures 21. Using the conveying roller structures 21 to convey the glass facilitates the vertical movement of the cutter structure 53, preventing contact between the cutter structure 53 and the conveying assembly 20 during movement. Simultaneously, the cutter structure 53 can cut the film on both the upper and lower surfaces of the glass, ensuring consistent cuts. Furthermore, it eliminates the need for two sets of film-cutting assemblies 50, reducing the overall cost of the device.

[0044] The difference between the technical solution of Embodiment 2 and that of Embodiment 1 is that the dust-adhesive structure 32 includes a first roller, a second roller, a third roller, and a fourth roller. A continuous dust-adhesive section 3212 is provided on the first roller. The dust-adhesive section 3212 passes through the second and third rollers, and the membrane also passes through the second and third rollers. The dust-adhesive section 3212 adheres to the dust on the membrane, causing the dust to detach from the membrane. The dust-adhesive section 3212, now covered with dust, is wound around the fourth roller. In the technical solution of Embodiment 2, the dust-adhesive section 3212 is not reused, resulting in a better dust-adhesive effect.

[0045] In summary, after the upper coated roll passes through the combination of the pressure roller (force roller shaft 322) and the dust-adhesive roller (dust-adhesive roller shaft 321), dust particles and lint on the roll are adsorbed by the dust-adhesive roller and will not fall onto the glass surface; the film material naturally becomes flat after being combined; during the glass movement, it passes through the ion wind, reducing the risk of dust particles falling off, and at the same time eliminating the risk of undried water droplets.

Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this application.
