Description

Technical Field

[0001] This utility model relates to the field of solar module maintenance technology, specifically to a cleaning device for solar cell module production. Background Technology

[0002] During the production process of solar modules, solar cells are typically arranged in a matrix on a solar panel. The solar cells need to be installed in the form of ultra-thin silicon wafers. Some cutting fluid and other impurities may remain on the surface of the silicon wafers. They are then connected by series and parallel electronic circuits and encapsulated with transparent glass. During this process, there is a gap between the transparent glass and the aluminum frame. In some cases, rainwater may leak into the aluminum frame and come into contact with the connecting wires of the solar cells, causing damage to the solar panel. After the solar modules are manufactured, they need to be cleaned to improve the quality of the finished product.

[0003] According to Chinese Patent Publication No. CN213915096U, "A Cleaning Equipment for Solar Cell Module Production," the main process involves placing the product on the upper surface of a mesh conveyor belt, which then transports it to the lower surface of a cleaning tank. A high-pressure water pump pressurizes the water, which is then used to rinse the outer surface of the product through a cleaning port. This double-layer rinsing method ensures a more thorough cleaning. The rinsed water flows into a collection tank and then back into the high-pressure water pump. This mechanism effectively cleans the product and allows for water recycling, reducing waste and providing a good environmentally friendly feature.

[0004] During the assembly of solar modules, it is necessary to clean the surface of the modules to remove impurities such as grease and cutting fluid. When cleaning the surface of the modules with a high-pressure nozzle, the cleaning fluid can get stuck in the gap between the aluminum frame and the transparent glass. The water on the upper side of the solar modules is prone to stagnation. When the modules are processed in the drying oven, it is easy to form adhesion on the surface of the solar modules, resulting in a reduction in the cleaning effect.

[0005] Therefore, a cleaning device for solar cell module production is proposed to solve the problem that water on the upper side of the solar module tends to stagnate, and that untreated grease, cutting fluid and other impurities will form stains during subsequent drying, resulting in reduced cleaning effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is that water on the upper side of the solar module is prone to stagnation, and untreated grease, cutting fluid and other impurities will form stains when processed in the subsequent drying box, resulting in a reduction in the cleaning effect. Therefore, a cleaning device for solar cell module production is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a cleaning equipment for the production of solar cell modules, including a fixed frame, a drive motor, a rotating rod, a rotating column, a mesh conveyor belt and a photovoltaic module. The fixed frame has a first groove on its bottom side, and a receiving box is fixedly connected to the fixed frame at the bottom side of the first groove. Two water pumps are fixedly connected to the bottom of the receiving box, and the water pumps are connected to the bottom side of the receiving box. An extension pipe is fixedly connected to the output end of the water pump, and a water distribution pipe is fixedly connected to one end of the extension pipe. Spray nozzles are evenly fixedly connected to the opposite side of the two water distribution pipes. A groove is opened on the upper side of the receiving box, and an activated carbon plate is inserted into the groove. Two air pumps are fixedly connected to one side of the fixed frame, and air knives are fixedly connected to the output end of the air pumps. Both air knives correspond to the photovoltaic module. A guide plate is fixedly connected to the side of the fixed frame near the air knives.

[0008] As a preferred technical solution of this utility model, an auxiliary roller is in contact with the mesh conveyor belt. The auxiliary roller is rotatably connected to the fixed frame. By setting the auxiliary roller, the stability of the conveyor belt in transporting photovoltaic modules can be improved.

[0009] As a preferred technical solution of this utility model, a second groove is provided in the fixed frame, and an electric push rod is fixedly connected in the second groove. The output end of the electric push rod is fixedly connected to a pulley seat, and a pulley is rotatably connected in the pulley seat. By setting the electric push rod, pulley seat and pulley, it is easy to guide the photovoltaic module.

[0010] As a preferred technical solution of this utility model, a locking strip is fixedly connected to one side of the pulley seat. The locking strip has an L-shaped structure. By setting the locking strip, it can provide a limit when the photovoltaic module is in the correct position.

[0011] As a preferred technical solution of this utility model, an electric telescopic rod is fixedly connected inside the fixed frame, and a striking ball is fixedly connected to the output end of the electric telescopic rod. The striking ball corresponds to the mesh conveyor belt, and the electric telescopic rod drives the striking ball to strike the mesh conveyor belt, thereby promoting the water to fall.

[0012] This utility model has the following advantages: by setting water distribution pipes and nozzles in the fixed frame to clean the upper and lower sides of the photovoltaic module, and then the air pump draws compressed air and guides it through the guide plate, the airflow cleans the water in the gap between the photovoltaic module and the aluminum frame and the encapsulation glass, which can reduce the water stains left on the glass surface during subsequent drying and improve the cleaning effect.

[0019] Please refer to the following: Figure 1-4The cleaning equipment shown includes a fixed frame 1, a drive motor, a rotating rod 2, a rotating column 3, a mesh conveyor belt 4, and photovoltaic modules 5. It also includes a drying structure (not shown in the figure, used for drying the photovoltaic modules 5 after cleaning). The drive motor drives the rotating rod 2 to rotate, which in turn causes the rotating column 3 and the mesh conveyor belt 4 to rotate, thus moving the photovoltaic modules 5 within the fixed frame 1. A first groove 6 is provided on the bottom side of the fixed frame 1. A receiving box 7 is fixedly connected to the bottom side of the fixed frame 1 at the first groove 6. Two water pumps 8 are fixedly connected to the bottom end of the receiving box 7. The water pumps 8 draw water from the bottom side of the receiving box 7 and then enter the water distribution pipe 10 and nozzle 11 through an extension pipe, thereby cleaning the moving photovoltaic modules 5. The water pumps 8 and the bottom side of the receiving box 7... The water pump 8 is connected to an extension pipe at its output end. One end of the extension pipe is connected to a water distribution pipe 10. Spray nozzles 11 are evenly connected to the opposite sides of the two water distribution pipes 10. The upper side of the receiving box 7 has a groove and an activated carbon plate 9 is inserted into the groove. By setting the activated carbon plate 9, the grease can be retained, reducing impurities in the water to be reused. A filter screen is fixedly connected to the bottom side of the activated carbon plate 9. Two air pumps 12 are fixedly connected to one side of the fixed frame 1. Air knives 13 are fixedly connected to the output end of the air pumps 12. Both air knives 13 correspond to the photovoltaic module 5. The air pumps 12 draw compressed air and spray it out through the air knives 13 to clean the water on the surface of the photovoltaic module 5. A guide plate 14 is fixedly connected to the side of the fixed frame 1 near the air knives 13. The guide plate 14 can guide the airflow.

[0020] The mesh conveyor belt 4 has an auxiliary roller 15 in contact with it. The auxiliary roller 15 is rotatably connected to the fixed frame 1. By setting the auxiliary roller 15, it can provide support when the photovoltaic module 5 moves within the fixed frame 1.

[0021] The fixed frame 1 has a second groove 16, and an electric push rod 17 is fixedly connected in the second groove 16. The output end of the electric push rod 17 is fixedly connected to a pulley seat 18, and a pulley is rotatably connected in the pulley seat 18. The electric push rod 17 extends and drives the pulley to contact the photovoltaic module 5, thereby facilitating the guidance and calibration of the position of the photovoltaic module 5 on the mesh conveyor belt 4.

[0022] Among them, a retaining strip 19 is fixedly connected to one side of the pulley seat 18. The retaining strip 19 has an L-shaped structure. By setting the retaining strip 19, the photovoltaic module 5 can be limited.

[0023] An electric telescopic rod 20 is fixedly connected inside the fixed frame 1. A striking ball 21 is fixedly connected to the output end of the electric telescopic rod 20. The striking ball 21 corresponds to the mesh conveyor belt 4. The electric telescopic rod 20 drives the striking ball 21 to strike the mesh conveyor belt 4, generating vibration, which can cause the water to fall.

[0024] Working principle: The photovoltaic module 5 is placed on the mesh conveyor belt 4 and then moves within the fixed frame 1. The water pump 8 draws water from the receiving box 7 and passes it through the water distribution pipe 10 and the nozzle 11 to clean the surface of the photovoltaic module 5. Then, the air pump 12 draws compressed air and sprays it out through the air knife 13. After contacting the guide plate 14, the airflow generates an oblique force and blows away the water in the gap between the photovoltaic module 5 and the encapsulation glass, thereby controlling the amount of water adhering to the photovoltaic module 5, which can improve the subsequent drying speed and reduce the formation of water stains during drying.
