Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel coating technology, and in particular to a pressure coating device for photovoltaic modules. Background Technology

[0002] Against the backdrop of the current rapid development of the photovoltaic industry, the installation of photovoltaic modules has nearly reached saturation, making the operation and maintenance of photovoltaic modules particularly important. Cleaning and coating technologies for photovoltaic module surfaces are gradually becoming key solutions for improving system efficiency and extending lifespan. According to data from the International Renewable Energy Agency (IRENA), global photovoltaic power plants suffer an average annual power generation efficiency loss of 6-15% due to environmental factors, while the application of functional coatings can reduce this loss to less than 3%, highlighting the core value of coating technology. In the future, with the development of new battery technologies such as perovskite, matched encapsulation coatings will become crucial for breaking through the 30% conversion efficiency bottleneck. Photovoltaic coating has transformed from an auxiliary technology into a core element affecting LCOE (Levelized Cost of Electricity), making it an inevitable choice for technological development.

[0003] Currently, the coating of photovoltaic modules in power plants mainly relies on manual operation, which has key drawbacks: the pressure applied during manual coating fluctuates greatly (pressure control accuracy is only ±0.1N), and the manual positioning accuracy is insufficient (error ±2mm), resulting in coating accumulation or missing parts, significant uniformity deviation (porosity >5%), which seriously affects the power generation efficiency and service life of photovoltaic modules (such as causing hot spot effect, failure of anti-reflection function, etc.). Moreover, manual coating is costly and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a pressure coating device for photovoltaic modules to solve the problems existing in the prior art, improve coating uniformity, ensure the power generation efficiency and service life of photovoltaic modules, and reduce labor costs and improve coating efficiency.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a pressure coating device for photovoltaic modules, including an X-axis linear module, a Y-axis linear module, a Z-axis linear module, a pressure sensor, a coating roller, and an injection pump.

Detailed Implementation

[0021] 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.

[0022] The purpose of this invention is to provide a pressure coating device for photovoltaic modules to solve the problems existing in the prior art, improve coating uniformity, ensure the power generation efficiency and service life of photovoltaic modules, and reduce labor costs and improve coating efficiency.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1As shown, this embodiment provides a photovoltaic module pressure coating equipment, including an X-axis linear module 1, a Y-axis linear module 2, a Z-axis linear module 3, a pressure sensor 4, a coating roller 5, and an injection pump 6. The two X-axis linear modules 1 are arranged in parallel and spaced apart. The two ends of the Y-axis guide rail 7 of the Y-axis linear module 2 are fixedly connected to the X-axis guide rail sliders 8 of the two X-axis linear modules 1, respectively. The Z-axis guide rail 14 of the Z-axis linear module 3 is fixed on the Y-axis slider of the Y-axis linear module 2. A mounting bracket 10 is fixedly installed on the Z-axis slider 9 of the Z-axis linear module 3. The coating roller 5 is rotatably connected to the coating bracket 11. The axis of the coating roller 5 is parallel to the XY plane. The upper end of the coating bracket 11 is connected to the mounting bracket 10 through the pressure sensor 4. The injection pump 6 is installed on the mounting bracket 10. The inlet end of the injection pump 6 is connected to the feeding container, and the outlet end is connected to the material distribution pipe 12. The material distribution pipe 12 is arranged above the coating roller 5 and is used to evenly distribute the material onto the coating roller 5.

[0025] In use, the coating is drawn by the injection pump 6 and evenly distributed on the coating roller 5 through the cloth tube 12. The coating roller 5 can be precisely controlled by the X-axis linear module 1, Y-axis linear module 2 and Z-axis linear module 3 to improve positioning accuracy. With the help of the pressure sensor 4, the pressure fluctuation applied by the coating roller 5 can be controlled within a small range. Thus, under the drive of the X-axis linear module 1, a more uniform coating is obtained on the surface of the photovoltaic module through the coating roller 5, improving the coating uniformity and ensuring the power generation efficiency and service life of the photovoltaic module. Moreover, the use of mechanical equipment for coating can reduce labor costs and improve coating efficiency compared with manual coating.

[0026] In this embodiment, the feeding tube 12 is parallel to the axis of the coating roller 5, and both ends of the feeding tube 12 extend to both ends of the coating roller 5. The bottom of the feeding tube 12 is uniformly provided with multiple discharge holes along the axial direction. Through the uniformly arranged multiple discharge holes, the coating can fall evenly onto the coating roller 5, ensuring that the coating is uniform and consistent on the coating roller 5.

[0027] In this embodiment, the fabric tube 12 is a round tube, but it is not limited to a round tube; other shapes such as square tubes are also acceptable.

[0028] In this embodiment, both ends of the fabric tube 12 are fixed to the coating bracket 11 to ensure that the position of the fabric tube 12 relative to the coating roller 5 remains unchanged, thus avoiding the influence of the uniformity of the fabric due to the movement of the position of the fabric tube 12.

[0029] In this embodiment, the X-axis linear module 1, Y-axis linear module 2, and Z-axis linear module 3 all adopt a ball screw linear module structure. Using ball screw linear modules offers convenient and high-precision control. Closed-loop control is achieved using X / Y / Z three-axis precision guideways (positioning accuracy ±0.01mm), C5-grade ball screws (repeatability ±1μm), and pressure sensor 4. Pressure fluctuations can be controlled within ±0.001N, achieving sub-micron-level displacement compensation, and coating thickness can be precisely controlled within 100-200nm (deviation ≤±3%).

[0030] In this embodiment, the inlet end of the injection pump 6 is connected to the feeding container through the feed pipe, and the outlet end is connected to the distribution pipe 12 through the discharge pipe.

[0031] In this embodiment, infrared limit sensors are provided at both ends of the X-axis linear module 1, both ends of the Y-axis linear module 2, and both ends of the Z-axis linear module 3. The use of infrared limit sensors prevents overtravel during movement, improving the safety of the device.

[0032] In this embodiment, the X-axis guide rail 13, Y-axis guide rail 7 and Z-axis guide rail 14 of the X-axis linear module 1 are all stainless steel guide rails. The surfaces of the X-axis guide rail 13, Y-axis guide rail 7 and Z-axis guide rail 14 are coated with polytetrafluoroethylene coating to prevent corrosion and improve service life.

[0033] In this embodiment, a PLC controller is also included. The X-axis linear module 1, Y-axis linear module 2, Z-axis linear module 3, pressure sensor 4, and injection pump 6 are all electrically connected to the PLC controller. The PLC controller can automatically control the X-axis linear module 1, Y-axis linear module 2, Z-axis linear module 3, and injection pump 6, and can provide feedback control to the X-axis linear module 1, Y-axis linear module 2, and Z-axis linear module 3 based on the detection value of pressure sensor 4. When pressure sensor 4 detects a momentary overload, the PLC controller can immediately initiate an emergency retraction program to control the Z-axis to rise and the X-axis to move in the opposite direction, avoiding scratches on the substrate.

[0034] This utility model, through technological innovation, systematically solves the core defects of manual coating and the application limitations of traditional equipment, achieving breakthroughs in precision, efficiency, and adaptability, and providing key technical support for the efficient operation and maintenance of photovoltaic power plants.
