Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic sheet manufacturing, and more specifically, particularly relates to a cleaning device for photovoltaic sheet processing. Background Art

[0002] Photovoltaic cells, or solar photovoltaic cells, are devices that use solar energy to generate electricity. They are mainly composed of crystalline silicon cells, packaging materials, back panels, glass panels and frames. The main purpose is to process semiconductor materials into devices that can convert solar energy into electrical energy. The manufacturing of photovoltaic cells generally includes the following processes: 1. Quartz sand reduction: extract high-purity polysilicon from quartz sand; 2. Silicon wafer manufacturing: including ingot casting, crystal pulling, slicing and other steps; 3. Cell manufacturing: including texturing of the silicon wafer surface, forming a PN junction on the silicon wafer surface through a high-temperature diffusion process, as well as etching, coating, screen printing and other steps; 4. Cleaning before packaging: During the production process, if there are impurities such as dirt, dust, organic matter or metal particles on the surface of the battery cell, it will seriously affect the absorption of light, so it needs to be cleaned.

[0003] 5. Packaging: including layout, lamination, framing and other processes.

[0004] The Chinese patent publication number is: CN117013946A, a photovoltaic panel cleaning device. The photovoltaic panel cleaning device of the present invention is directly assembled on the surface of the photovoltaic sheet, which can conveniently and effectively clean the photovoltaic panel, and the normal power generation of the photovoltaic sheet is not affected during the treatment process, which is labor-saving and efficient; it has low requirements on the environment, etc., and is suitable for photovoltaic panels in any terrain environment such as mountains, and has a wide range of applications.

[0005] Existing photovoltaic panel cleaning equipment has the following disadvantages when used: 1. When cleaning the existing photovoltaic cells before packaging, usually only a straight-row cleaning brush is provided. However, when the existing photovoltaic cells are placed for cleaning, there may be a certain height difference on the surface of the photovoltaic cells due to the installation error of the placement fixing frame and the different production specifications of the photovoltaic cells themselves. The straight-row cleaning brush is difficult to adapt to the photovoltaic cells at different heights, which may result in the concave parts not being cleaned, etc., resulting in poor cleaning effect. In addition, the friction force of the straight-row cleaning brush on the photovoltaic cells is small, and it needs to be cleaned back and forth, which has low cleaning efficiency. 2. When cleaning existing photovoltaic cells before packaging, the photovoltaic cells are generally placed on a stand. Due to different placement positions or different specifications of the placement brackets, the angles of arrangement of the photovoltaic cells are often different. Existing equipment is difficult to adapt to the cleaning of photovoltaic cells at various angles, and has certain limitations when used, resulting in poor cleaning effects, and subsequent manual secondary cleaning is required.

[0021] Working principle: The first step is that during the production process of the photovoltaic sheet 1, if there are impurities such as dirt, dust, organic matter or metal particles on the surface of the photovoltaic sheet 1, it will seriously affect the absorption of light. Therefore, before the photovoltaic sheet is packaged, it needs to be cleaned. When cleaning the photovoltaic sheet 1, the user can first place the photovoltaic sheet 1 of the batch to be cleaned on the fixed frame, and first clamp the clamping grooves 24 on both sides of the base 2 on the two ends of the photovoltaic sheet 1 fixed frame, and then adjust the inclination angle of the straight plate 6 to make the inclination angle of the straight plate 6 match the photovoltaic sheet 1.

When cleaning is not required, the two first telescopic rods 23 can be compressed to make the two bases 2 close to each other, thereby reducing the space occupied by the device and facilitating storage. The third step, after completing the fixation of the equipment, the user can adjust the inclination angle of the adjusting straight plate 6 according to the inclination angle of the photovoltaic sheet 1 to adapt it to the angle of the photovoltaic sheet 1, the user can start the servo motor 5 to drive the first threaded rod 51 to rotate forward or reversely, the first threaded rod 51 rotates through the first thread groove 54 to drive the connecting rod 53 to slide, the sliding of the connecting rod 53 drives the two first racks 52 to slide, the sliding of the first rack 52 drives the first gear 62 to rotate clockwise or counterclockwise, the two first gears 62 rotate through the two circular shafts 61 to drive the adjusting straight plate 6 to rotate, the adjusting straight plate 6 rotates to change its inclination angle, after rotating the adjusting straight plate 6 to make its angle adapt to the inclination angle of the photovoltaic sheet 1, the user can turn off the servo motor 5; The device is provided with an adjustable straight plate 6 with an angle that can be adjusted.

It can adapt to the angles of different photovoltaic sheets 1 by adjusting its own angle, has high adaptability, and ensures maximum fit with the surface of the photovoltaic sheet 1 to ensure the cleaning effect. Step 4. After completing the angle adjustment of the adjustment straight plate 6, the user can adjust the position of the diverter 79 according to the position of the top of the photovoltaic sheet 1. The user can rotate the second threaded rod 68 forward or reversely. The second threaded rod 68 rotates through the second threaded groove 77 to drive the fixed block 76 to move. The fixed block 76 moves to drive the position of the diverter 79 to move. The user can adjust the position of the diverter 79 to a position close to the top of the photovoltaic sheet 1, so that the nozzle 75 on the diverter 79 can spray from the top of the photovoltaic sheet 1 when spraying water, so that the cleaning water can be washed from the top of the photovoltaic sheet 1 from top to bottom; The device is provided with a position-adjustable diverter 79 and a nozzle 75. During actual cleaning, the position of the diverter 79 can be adjusted according to the position of the top of the photovoltaic sheet 1, so that the device can adapt to the height of the photovoltaic sheet 1 when spraying cleaning water, so that the water flow can be flushed from top to bottom. It is easy to adjust and can adapt to a variety of photovoltaic sheets 1 with different specifications for flushing and cleaning; By setting a single diverter 79 with adjustable position, the device can save water compared with the direct-discharge type spraying equipment in the prior art, and can realize the water flow from top to bottom, which can ensure the showering effect while avoiding the waste of water near the bottom. The position of the diverter 79 is adjustable, and when some positions are not cleaned up, the diverter 79 can be adjusted to change the showering position, which has good flexibility in use. The fifth step, after completing the above-mentioned adjustment work, the user can start the water pump in the water tank 21, and the pumped water is sprayed out from the nozzle 75 at the side end of the diverter 79 through the water guide hose 22 to rinse the photovoltaic sheet 1. At this time, the user can start the double-headed motor 32. The double-headed motor 32 starts to drive the rotating shafts 33 on both sides to rotate. The rotation of the rotating shafts 33 drives the movable wheels 34 to rotate and drive the T-shaped movable seat 3 to move. The movement of the T-shaped movable seat 3 will drive each cleaning brush 84 on the adjustment straight plate 6 through the C-shaped seat 4 to scrape and clean the photovoltaic sheet 1. When the rotating shaft 33 rotates, it will also drive the first push rod 35 to rotate. When the first push rod 35 rotates and contacts the end of the transmission rod 9, the first push rod 35 will push the transmission rod 9 to move upward. The upward movement of the transmission rod 9 will drive the arc rod 92 to move upward. The upward movement of the arc rod 92 will stretch the third spring 91. When the arc rod 92 moves to When the second push rod 71 moves upward, it will push the second push rod 71 to move, and the movement of the second push rod 71 will drive the second cross bar 72 to move. At this time, the first spring 64 is compressed, and the movement of the second push rod 71 will also drive the second rack 7 to move. The movement of the second rack 7 will drive the T-shaped slide bar 73 to slide in the T-shaped slide groove 69. The movement of the second rack 7 will drive each second gear 81 to rotate, and the rotation of each second gear 81 will drive the fixed column 8 to rotate. The rotation of each fixed column 8 will drive each cleaning brush 84 to rotate through the second telescopic rod 82. When the first push rod 35 rotates away from the end of the transmission rod 9, the third spring 91, the arc rod 92 and the second rack 7 will be reset respectively under the drive of the third spring 91 and the first spring 64, which will drive each cleaning brush 84 to rotate in the opposite direction. This reciprocating movement drives the cleaning brush 84 to realize reciprocating rotation during cleaning, thereby cleaning the photovoltaic sheet 1; The device is provided with a first push rod 35, a transmission rod 9, an arc rod 92 and a second rack 7. When the movable wheel 34 drives the T-shaped movable seat 3 to move, each cleaning brush 84 can be driven to rotate back and forth to clean the photovoltaic sheet 1. The reciprocating rotation of the cleaning brush 84 can generate stronger friction and impact force, and can more effectively remove stubborn stains and dust. Compared with simple linear movement cleaning, the cleaning effect is better, and the movement of the second rack 7 can drive multiple cleaning brushes 84 to rotate at the same time, without the need for an additional power source to drive, thereby ensuring the cleaning effect while saving energy. The device is provided with a plurality of fixed columns 8 and cleaning brushes 84 on the adjusting straight plate 6, and a second telescopic rod 82 and a second spring 83 are fixedly installed between each cleaning brush 84 and the fixed column 8, that is, each second spring 83 will generate a moving thrust for the cleaning brush 84, so that the cleaning brush 84 can always be attached to the surface of the photovoltaic sheet 1, avoiding the phenomenon that a certain height difference on the surface of the photovoltaic sheet 1 caused by different production specifications of the photovoltaic sheet 1, height error of the installation fixing frame, etc., makes the cleaning brush 84 unable to be attached for cleaning. In addition, a plurality of cleaning brushes 84 are provided, so that each cleaning brush 84 can clean the surface of the photovoltaic sheet 1 in a modular manner, which can better adapt to the height angle changes of each module than the straight plate type setting, and has better adaptability.
