[0036] The upper end of the roller conveyor belt assembly 11 is fixedly connected to a guide baffle 22, and the end of the upper end of the roller conveyor belt assembly 11 close to the two splints 16 is fixedly connected to a brush cleaning machine 23, and the end of the upper end of the roller conveyor belt assembly 11 close to the brush cleaning machine 23 is fixedly connected to a coating nozzle 24, and the end of the roller conveyor belt assembly 11 close to the coating nozzle 24 is fixedly connected to a coating liquid tank 25, and the coating nozzle 24 and the coating liquid tank 25 are connected.

When the large-size photovoltaic glass is subjected to the production coating and tempering treatment operation, the staff places the large-size photovoltaic glass on the roller conveyor belt assembly 11. The roller conveyor belt assembly 11 is a three-section roller conveyor belt. During the placement operation, the guide baffle 22 installed on the roller conveyor belt assembly 11 plays a guiding role. At this time, the roller conveyor belt assembly 11 is started, and the roller conveyor belt assembly 11 conveys the large-size photovoltaic glass forward for production and processing. During the transportation process, the photovoltaic glass first passes through the brush cleaning machine 23.

Through automated production, the impact of human factors on the production process can be reduced, production costs can be reduced, and the competitiveness of the enterprise can be improved.

[0037] In response to the problems existing in the prior art, the utility model provides a coating and tempering device for the production of large-size photovoltaic glass. Before the photovoltaic glass is conveyed and processed, the rotation direction and number of rotations of the output shaft of the motor 13 are set according to different sizes and shapes. The motor 13 is started, and the output shaft of the motor 13 drives the rectangular plate 14 to rotate. The rotation of the rectangular plate 14 drives the two connecting rods 15 to rotate. The two connecting rods 15 are pushed and rotated to pull the two clamps 16 to slide. When the photovoltaic glass is conveyed and processed, it is limited by two clamps 16 with adjustable spacing to ensure the stability of its placement during the conveying process, effectively prevent the photovoltaic glass from positional displacement during the conveying process, and enable the photovoltaic glass to always remain in the correct position of the conveyor belt, thereby ensuring the accuracy of subsequent processing operations. The two clamps 16 with adjustable spacing can adapt to photovoltaic glass of different sizes, thereby improving the flexibility and stability of the production device.

[0038] Working principle:

[0039] In the first step, when the large-size photovoltaic glass is subjected to the production coating and tempering operation, the staff places the large-size photovoltaic glass on the roller conveyor belt assembly 11. The roller conveyor belt assembly 11 is a three-section roller conveyor belt. During the placement operation, the guide baffle 22 installed on the roller conveyor belt assembly 11 plays a guiding role. At this time, the roller conveyor belt assembly 11 is started, and the roller conveyor belt assembly 11 conveys the large-size photovoltaic glass forward for production and processing. During the transportation process, the photovoltaic glass first passes through the brush cleaning machine 23. The brush cleaning machine 23 is provided with a brush roller for removing dust, foreign particles, etc. on the surface of the photovoltaic glass. The glass surface is physically brushed by a rotatable brush. After being cleaned, the photovoltaic glass is then transported through the coating nozzle 24 At the lower end, the coating liquid tank 25 is used to store the coating liquid. The coating nozzle 24 is connected to the coating liquid tank 25. The coating nozzle 24 can evenly spray the coating liquid stored in the coating liquid tank 25 on the surface of the photovoltaic glass. The coating nozzle 24 adopts an atomizing nozzle, which can atomize the coating liquid into tiny particles with a diameter of several microns to tens of microns. This can make the coating more uniform and improve the coating quality. During the coating operation, water-based coating materials are used instead of traditional organic solvent coating materials to reduce the emission of volatile organic compounds, pay attention to environmental protection and sustainable development, and adopt pollution-free, low-energy consumption production processes and materials to reduce the impact on the environment. At this time, the photovoltaic glass is continuously transported through and stays inside the coating dryer 26 for a certain period of time. Through the coating dryer 26 uses circulating hot air to volatilize the solvent in the coating layer and quickly dry the coating layer. After the coating is completed, the photovoltaic glass is conveyed to the heating furnace 27 for heating and tempering. The heating furnace 27 uses heating elements (electric heating wires) to evenly heat the glass so that it is heated to a point close to the softening point. At this time, the cooling fan in the heating furnace 27 quickly and evenly cools it, so that a temperature difference is formed between the inside and the surface of the glass, and tensile stress is formed inside the glass. The existence of this compressive stress greatly improves the strength of the glass and significantly enhances its impact resistance. By controlling parameters such as tempering temperature, time and cooling speed, the stress concentration inside the glass is reduced, and the mechanical strength and safety of the glass are improved. After the coating and tempering treatment is completed, the glass is conveyed through the rubber sleeve 18 and passed through the inspection The multiple sensing sensor elements arranged in the detector 28 (such as an optical interference thickness gauge, which uses the principle of light interference to accurately measure the thickness of the coating layer, and a spectrophotometer to measure the transmittance and reflectance curves of the glass at different wavelengths to evaluate the improvement effect of the coating on the optical properties of the glass, etc.) are used to detect its thickness, optical properties, etc. to ensure product quality. The photovoltaic glass after the coating and tempering treatment has higher transmittance, lower reflectivity and better corrosion resistance, which can improve the power generation efficiency and service life of the photovoltaic module. The brush cleaning machine 23, the coating nozzle 24, the coating liquid tank 25, the coating dryer 26, the heating furnace 27, and the detector 28 are used to realize the automated production process of coating and tempering of large-size photovoltaic glass.Improve production efficiency and product quality through automated production, reduce the impact of human factors on the production process, reduce production costs, and improve the competitiveness of enterprises.

[0040] In the second step, before the photovoltaic glass is conveyed and processed, the rotation direction and number of rotations of the output shaft of the motor 13 are set according to different sizes and shapes, and the motor 13 is started. The output shaft of the motor 13 drives the rectangular plate 14 to rotate, and the rotation of the rectangular plate 14 drives the two connecting rods 15 to rotate. The two connecting rods 15 are pushed and rotated to pull the two clamping plates 16 to slide. When the photovoltaic glass is conveyed and processed, it is limited by two clamping plates 16 with adjustable spacing to ensure the stability of its placement during the conveying process, effectively prevent the photovoltaic glass from shifting in position during the conveying process, and make the light The photovoltaic glass can always be kept in the correct position on the conveyor belt, thereby ensuring the accuracy of subsequent processing operations, and the two splints 16 with adjustable spacing can adapt to photovoltaic glasses of different sizes, improving the flexibility and stability of the production equipment. During the transportation process, the photovoltaic glass will be squeezed and pressed against the two sets of splints 16 to rotate, and the roller shaft 17 outside the two sets of splints 16 will fit the surface of the photovoltaic glass to avoid scratching its surface. The splint 16 slides outside the slide rail 19 through the slide groove 21, and its sliding trajectory is limited by the slide rail 19, making the sliding smoother, thereby improving the controllability of its sliding process.
