Technical Field

[0001] This utility model relates to the field of photovoltaic panel production equipment technology, and in particular to a self-cleaning coating production line for photovoltaic panels. Background Technology

[0002] A photovoltaic (PV) panel, also known as a solar panel, is a device that converts solar energy into electrical energy. It is mainly composed of solar cells, which can convert the light energy of sunlight into direct current. PV panels are usually composed of multiple solar cell units connected in series or parallel, and these units are mainly made of silicon materials (such as monocrystalline silicon or polycrystalline silicon).

[0003] In the production process of photovoltaic panels, one step involves applying liquid adhesive to the photovoltaic panel substrate. However, existing coating equipment typically requires cleaning the area of ​​the photovoltaic panel substrate to be coated with liquid adhesive before applying the liquid adhesive to prevent dust and impurities from causing insufficient adhesion between the liquid adhesive and the photovoltaic panel substrate. This requires two steps: cleaning the photovoltaic panel substrate before applying the liquid adhesive, which affects the production efficiency of photovoltaic panels. Therefore, to solve this problem, a self-cleaning coating production line for photovoltaic panels is proposed. Utility Model Content

[0028] As a technical optimization of this utility model, two connecting plates 17 are symmetrically installed at the bottom of the mounting plate 15, and an mounting shaft is rotatably installed between the two connecting plates 17. The roller 18 is fixedly sleeved on the outer wall of the mounting shaft. The side of the roller 18 is connected to the filling port 31. Liquid glue is loaded in the annular cavity. The top end of the spring 27 is installed at the bottom of the sleeve 25, and the bottom end of the spring 27 is installed at the top of the collection box 28. The guide rod 26 is located in the inner ring of the spring 27. Through the cooperation of the sleeve 25, the guide rod 26 and the spring 27, the cleaning brush 29 can always maintain contact with the top of the photovoltaic substrate when the bottom of the outer wall of the roller 18 contacts the top of the photovoltaic substrate, which is convenient for cleaning the top of the photovoltaic substrate.

[0029] As a technical optimization of this utility model, the reciprocating motion mechanism includes a first fixed plate 3 and a second fixed plate 4 symmetrically installed on the top of the base plate 1. A reciprocating screw 5 is rotatably installed between the first fixed plate 3 and the second fixed plate 4. An internal threaded block 6 is threaded onto the reciprocating screw 5. An electric telescopic rod 13 is installed at the bottom of the internal threaded block 6. A limiting component for limiting the reciprocating screw 5 is provided between the first fixed plate 3 and the second fixed plate 4.

[0030] As a technical optimization of this utility model, the limiting component includes a slide rod 8 installed between the first fixed plate 3 and the second fixed plate 4, and a sliding sleeve 7 installed on the top of the internal thread block 6. The sliding sleeve 7 is slidably sleeved on the slide rod 8. Through the cooperation of the slide rod 8 and the sliding sleeve 7, the internal thread block 6 can be limited, so that the internal thread block 6 can perform reciprocating cyclic motion on the reciprocating screw 5.

[0031] As a technical optimization of this utility model, a motor 10 and a protective shell 9 are installed on the side of the first fixed plate 3 away from the reciprocating lead screw 5. The output shaft of the motor 10 passes through the first fixed plate 3 and is connected to the reciprocating lead screw 5. The motor 10 is located inside the protective shell 9. A bearing 11 is installed on the side of the second fixed plate 4 close to the reciprocating lead screw 5. The end of the reciprocating lead screw 5 is installed in the inner ring of the bearing 11. The bearing 11 can provide guidance for the rotation of the reciprocating lead screw 5.

[0032] As a technical optimization of this utility model, a connecting block 12 is installed at the bottom of the internal thread block 6, an electric telescopic rod 13 is installed at the bottom of the connecting block 12, a reinforcing block 14 is installed at the end of the piston rod of the electric telescopic rod 13, and the reinforcing block 14 is installed at the top of the mounting plate 15. The reinforcing block 14 can increase the connection strength between the mounting plate 15 and the end of the piston rod of the electric telescopic rod 13.

[0033] As a technical optimization of this utility model, a bearing plate 2 is installed on the top of the base plate 1, and the bearing plate 2 is located below the roller 18.

[0034] When using this invention, if liquid adhesive needs to be applied to the photovoltaic panel substrate, first place the photovoltaic panel substrate to be coated with liquid adhesive on the support plate 2, start the motor 10, the output shaft of the motor 10 drives the reciprocating screw 5 to rotate, so that the internal thread block 6 reciprocates on the reciprocating screw 5. After adjusting the position of the internal thread block 6 to above one side of the photovoltaic panel substrate, stop, so that the mounting plate 15 is located above one side of the photovoltaic panel substrate.

[0035] At this time, the electric telescopic rod 13 is activated, and the piston rod of the electric telescopic rod 13 pushes the mounting plate 15 down. The downward movement of the mounting plate 15 drives the roller 18 and the cleaning brush 29 down until the bottom ends of the roller 18 and the cleaning brush 29 are in contact with the top of the photovoltaic panel substrate and then stop. At this time, the motor 10 is activated, and the output shaft of the motor 10 drives the reciprocating screw 5 to rotate, causing the internal thread block 6 to move laterally. In turn, the internal thread block 6 drives the electric telescopic rod 13 and the mounting plate 15 to move laterally. When the mounting plate 15 moves laterally, its cleaning brush 29 rubs against the top of the photovoltaic panel substrate. The cleaning brush 29 can be used to clean the top of the photovoltaic panel substrate. At the same time, the vacuum cleaner 16 is activated. The suction end of the vacuum cleaner 16 can collect and process the dust and impurities that fly up from the cleaning brush 29 through the collection box 28 and the suction hole 30 connected to the collection box 28, thereby completing the cleaning process of the photovoltaic panel substrate.

[0036] Furthermore, the top of the photovoltaic panel substrate is cleaned using the cleaning brush 29, and dust and impurities are collected and processed by the vacuum cleaner 16. Simultaneously, the mounting plate 15 provides a lateral force to the roller 18 as it moves laterally. The bottom of the outer wall of the roller 18 contacts the top of the photovoltaic panel substrate, and the roller 18 is rotatably mounted between two connecting plates 17. When the mounting plate 15 moves laterally, the roller 18 rolls on the top of the photovoltaic panel substrate. As the roller 18 rolls, the liquid adhesive loaded in the annular cavity inside the roller 18 is discharged through the liquid outlet 19, and then, as the roller 18 moves on the photovoltaic panel substrate... By rolling the top of the plate, liquid adhesive can be applied to the top of the photovoltaic panel substrate. This process combines cleaning and adhesive application into a single step, improving production efficiency and preventing re-contamination that could affect adhesion between the adhesive and the substrate.

[0037] Furthermore, when the roller 18 applies liquid adhesive to the top of the photovoltaic panel substrate, the scraper 21 can scrape off the excess liquid adhesive applied to the top of the photovoltaic panel substrate. This not only smooths out the liquid adhesive applied to the top of the photovoltaic panel substrate but also removes the excess liquid adhesive, preventing excessive liquid adhesive from being applied to the top of the photovoltaic panel substrate. The height of the scraper 21 can be adjusted by rotating the threaded rod 22, allowing for independent adjustment as needed.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
