Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass laser mold removal technology, specifically a surface cleaning device for glass mold removal pretreatment. Background Technology

[0002] Photovoltaic glass (also known as photovoltaic glass) is an indispensable key auxiliary material for solar photovoltaic modules. Its main function is to protect the fragile internal solar cells, while its excellent optical properties (high transmittance and low reflectance) are crucial for improving the overall photoelectric conversion efficiency of the module. However, in the hot and humid southern regions, the surface of photovoltaic glass is highly susceptible to mold growth due to the humid environment during transportation, storage, and processing. These mold spots not only significantly reduce the light transmittance of the glass, causing incident light loss, but also directly affect the photoelectric conversion efficiency of the photovoltaic module, ultimately leading to a decrease in power generation and economic losses.

[0003] To ensure product quality and component performance, photovoltaic glass must undergo a rigorous laser mold removal process before encapsulation. This process typically includes: material loading → surface cleaning → laser mold removal → quality inspection → sorting and packaging. Currently, the industry commonly uses two main methods for glass surface cleaning:

[0004] 1. High-pressure air purging: This method mainly relies on high-speed airflow to remove floating dust and loose particles from the glass surface. Its disadvantages are that it is not very effective at removing stubborn stains (such as oil stains, sticky residues, and some early mold spots) as well as small impurities embedded in the surface microstructure, and it cannot solve the problem of liquid residue.

[0005] 2. Ordinary water rinsing: This method uses water to rinse the glass surface. While it can remove some surface dust and water-soluble dirt, it is ineffective at removing stubborn, tightly adhered impurities (such as dried stains). More seriously, ordinary water rinsing often leaves a large amount of water stains or a water film on the glass surface. This residual moisture can absorb or scatter laser energy during subsequent laser treatment, reducing the efficiency of mold removal.

[0006] In summary, existing cleaning methods, such as high-pressure air purging and ordinary water rinsing, generally suffer from two major problems: incomplete cleaning (ineffective against stubborn impurities) and easy retention of moisture. Therefore, this application provides a surface cleaning device for glass mold removal pretreatment to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a surface cleaning device for pretreatment of glass mold removal, comprising a housing, the housing including a lower housing 2 and an upper housing 3, and along the glass conveying direction, the lower housing 2 and the upper housing 3 are respectively provided with corresponding conveying roller groups and cleaning roller groups. The cleaning roller group includes several sponge rollers 5 arranged along the glass conveying direction. The central shaft of the sponge roller 5 is a hollow structure with one end open, and the open end of the central shaft of the first sponge roller 5 in contact with the glass is rotatably provided with a water pipe 6, and the open end of the central shaft of the remaining sponge rollers 5 is rotatably provided with a hot air pipe 7. The peripheral side of the central shaft of the sponge roller 5 is provided with uniformly distributed through holes. Cleaning water enters the corresponding sponge roller 5 through the water pipe 6, so that the moistened sponge roller 5 cleans the glass; hot air enters the corresponding sponge roller 5 through the hot air pipe 7, so as to dry the glass surface.

[0022] Furthermore, the lower housing 2 is provided with a threaded cylinder 21 on its side, and the upper housing 3 is provided with a sleeve 31 on the side corresponding to the threaded cylinder 21. A screw is rotatably provided inside the sleeve 31. The distance between the upper housing 3 and the lower housing 2 is adjusted according to the glass thickness, thereby adjusting the distance between the upper and lower drive rollers 4 and the distance between the upper and lower sponge rollers 5. The adjustment method is as follows: rotate the screw 32. During the rotation of the screw 32, the upper housing 3 is moved up or down, thereby adjusting the distance between the upper housing 3 and the lower housing 2.

[0023] Furthermore, the bottom of the lower housing 2 is provided with support legs 1.

[0024] Furthermore, the conveying roller assembly includes several drive rollers 4 rotatably mounted on the housing. The ends of the drive rollers 4 are provided with sub-gears, and the several sub-gears are driven by a chain. One drive roller 4 is provided with a driven gear at its end. The housing is provided with a drive motor, and the output shaft of the drive motor is provided with a driving gear. The driving gear and the driven gear are connected by a transmission chain. The cleaning roller assembly is located between two adjacent drive rollers 4. The drive rollers 4 are polyurethane rubber rollers.

[0025] The distance between the two corresponding sponge rollers 5 is smaller than the distance between the two corresponding drive rollers 4, so that the sponge rollers 5 have a certain squeezing force on the glass, improving the cleaning effect on the glass surface.

[0026] Furthermore, the sponge roller 5 is rotatably mounted on the housing, and one end of the sponge roller 5 is provided with a secondary gear. Several secondary gears are connected by chain drive. One end of the sponge roller 5 is provided with a driven wheel. The housing is provided with a motor, and the output shaft of the motor is provided with a driving wheel. The driving wheel and the driven wheel are connected by drive chain drive. Both the driving wheel and the driven wheel are gears.

[0027] The conveying roller groups and cleaning roller groups on the lower housing 2 and the upper housing 3 are arranged symmetrically. The corresponding upper and lower conveying roller groups work together to convey the glass, and the corresponding upper and lower cleaning roller groups work together to clean the upper and lower surfaces of the glass. There are three drive rollers 4 on both the upper and lower sides. The cleaning roller groups are set between two adjacent drive rollers 4 at the same height. Two cleaning is achieved through two sets of cleaning roller groups, thereby improving the cleaning effect on the glass.

[0028] The drive motor and motor used in this utility model are all common electronic components in the prior art. Their working methods and circuit structures are well-known technologies and will not be described in detail here. The motor drives the gear and the transmission method through the chain is a common drive mechanism in the prior art.

[0029] When using:

[0030] by Figure 3For example, the distance between the upper housing 3 and the lower housing 2 is adjusted according to the glass thickness, thereby adjusting the distance between the upper and lower drive rollers 4 and the distance between the upper and lower sponge rollers 5. The adjustment method is as follows: rotate the screw 32. During the rotation of the screw 32, the upper housing 3 is moved up or down, thereby adjusting the distance between the upper housing 3 and the lower housing 2.

[0031] Roller conveyors are installed on the left and right sides of the device. The roller conveyor on the right side transports the glass to the left. The glass is cleaned inside the device, and the cleaning method is as follows:

[0032] When the glass passes through the drive roller 4, the upper and lower drive rollers 4 work together to transport the glass, so that the glass moves horizontally inside the housing.

[0033] When the glass passes through the sponge roller 5, the water in the water pipe 6 wets the sponge roller 5 through the through hole, and then the rotating and wet sponge roller 5 wipes the glass.

[0034] When the wiped glass passes through the subsequent sponge roller 5, the hot air discharged by the sponge roller 5 dries the glass surface. At the same time, the hot air dries the sponge roller 5 that has water on it, thus completing the cleaning operation of the glass surface.

[0035] This invention employs an adjustable shell structure, making it suitable for glass of various thicknesses. It allows for sequential wet and dry wiping of the glass, simultaneously cleaning both the upper and lower surfaces. This improves the cleaning effect on the glass surface, prevents moisture residue, and is simple and convenient to operate.

[0036] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
