[0025] 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.

[0026] Please refer to Figures 1-5. The present invention provides a precision degreasing system for aluminum coil uncoiling operations, including a base 1. The upper surface of the base 1 is provided with a cleaning tank 2, and the surface of the base 1 is rotatably provided with vertically erected aluminum coil guide rollers 3. The aluminum coil guide rollers 3 are arranged on both sides of the surface of the base 1 to limit the aluminum coil 4 from standing and passing through the cleaning tank 2. The two ends of the base 1 can be respectively provided with an aluminum coil unwinding mechanism and a rewinding mechanism. The unwinding mechanism is used to unwind the coiled aluminum strip, and the rewinding mechanism is used to rewind the unwinded aluminum coil. The unwinding mechanism and the rewinding mechanism are conventional existing structures, which will not be described in detail here.

[0027] In this embodiment, the opening of the cleaning tank 2 is provided with, from left to right, an identification unit 5 for identifying oil stains on the surface of the aluminum coil 4, a spraying unit 6 for spraying water-based cleaner onto the surface of the aluminum coil 4, a wiping unit 7 for wiping the oil stains on the surface of the aluminum coil 4, and a drying unit 8 for drying the surface of the aluminum coil 4. In use, the aluminum coil 4 is first unfolded and passed between the aluminum coil guide rollers 3. The identification unit 5 is used to identify the oil stains on the surface of the aluminum coil 4. When oil stains are identified, water-based cleaner is sprayed onto the surface of the aluminum coil 4 by the spraying unit 6. The water-based cleaner helps to decompose and soften the oil stains on the surface of the oil stains, making them easier to wipe off. After the water-based cleaner is sprayed onto the surface of the aluminum coil 4, the oil stains on the surface of the aluminum coil 4 are wiped off by the wiping unit 7. Finally, the surface of the aluminum coil 4 is dried by the drying unit 8.

[0028] The identification unit 5 includes an industrial camera 51 fixed on both sides of the opening of the cleaning tank 2. The industrial camera 51 is used to take pictures of the surface of the aluminum coil 4. The industrial camera 51 is connected to a control system. The control system is connected to the spraying unit 6. When the industrial camera 51 captures an image of oil stains, the control system sends a control signal to the spraying unit 6 to realize automatic spraying.

[0029] As shown in Figure 3, the wiping unit 7 includes a fixed bracket 71 fixed on both sides of the opening of the cleaning tank 2. The fixed bracket 71 is equipped with two sets of wiping belts 73 by two sets of driving mechanisms 72. The driving mechanism 72 can be a pulley structure driven by a motor. The side of the wiping belt 73 that contacts the aluminum coil 4 moves from top to bottom. During the movement from top to bottom, the oil stains on the surface of the aluminum coil 4 can be wiped away. The fixed bracket 71 is fixed with a spraying mechanism 74. The spraying mechanism 74 is used to spray water onto the lower inner surface of the two sets of wiping belts 73. Since water-based cleaning agents are easily soluble in water, the surface of the wiping belts 73 can be effectively rinsed clean by water.

[0030] As shown in Figure 3, a squeegee 75 is fixed on the outer surface of the wiping belt 73 by the fixed bracket 71. After the wiping belt 73 is sprayed with water, it will contain a lot of water. The squeegee 75 can scrape off the water on the surface of the wiping belt 73 to prevent excessive water from diluting the water-based cleaning agent and reducing its cleaning effect.

[0031] The spraying unit 6 includes a water-based cleaning agent tank 61 fixedly connected to the base 1, a first water pump 62, and a water-based cleaning agent nozzle 63. The water-based cleaning agent nozzles 63 are equidistantly arranged in the height direction of the aluminum coil 4. The water outlet of the water-based cleaning agent tank 61 is connected to the water inlet of the first water pump 62, and the water outlet of the first water pump 62 is connected to the water inlet of the water-based cleaning agent nozzle 63. When the industrial camera 51 captures an image of oil stains, water-based cleaning agent can be drawn from the water-based cleaning agent tank 61 by the first water pump 62 and sprayed onto the surface of the aluminum coil 4 through the water-based cleaning agent nozzle 63. Spraying water-based cleaning agent onto the oil stain surface helps to decompose and soften the oil stains, making them easier to wipe off by the wiping belt 73.

[0032] The spraying mechanism 74 includes a water spray pipe 741 fixed to the fixed bracket 71. The water spray pipe 741 is horizontally centered at the lower end of the two sets of wiping belts 73, and spray heads 742 are provided on both sides of the water spray pipe 741. The water spray pipe 741 is connected to a second water pump 743. The water inlet end of the second water pump 743 is connected to an external water pipe 744. By connecting the external power supply of the second water pump 743, the second water pump 743 draws water through the water pipe 744 to the water spray pipe 741, and then the spray heads 742 on both sides of the water spray pipe 741 spray water onto the surface of the two sets of wiping belts 73 respectively, which facilitates cleaning of the wiping belts 73.

[0033] A heating plate 9 is fixedly installed on the fixed bracket 71 above the wiper blade 75. The heating plate 9 heats up when energized and is used to further dry the wiping strip 73 when needed.

[0034] The drying unit 8 includes a fan fixed on the base 1. After the oil stains are wiped off by the wiping belt 73, the aluminum coil 4 moves to the area of ​​the drying unit 8 and the fan dries the surface moisture of the aluminum coil 4.

[0035] The control system includes a control cabinet 10 fixed on the base 1, as shown in Figure 4. The control cabinet 10 contains a data acquisition and processing module and a PLC module. The signal output terminal of the industrial camera 51 is connected to the signal input terminal of the data acquisition and processing module, the signal output terminal of the data acquisition and processing module is connected to the signal input terminal of the PLC module, and the signal output terminal of the PLC module is connected to the signal input terminal of the first water pump 62. The industrial camera 51 is used to capture images of the surface of the aluminum coil 4 and transmit the image data to the data acquisition and processing module. The data acquisition and processing module is used to receive the image data transmitted by the industrial camera 51 and... The data acquisition and analysis process involves the data acquisition and processing module sending a signal to the PLC module when oil stains are detected. The PLC module then sends a control signal to the signal input terminal of the first water pump 62, causing the first water pump 62 to start and spray water-based cleaning agent onto the surface of the aluminum coil 4. An industrial camera 51 acquires an image, and the data acquisition and processing module processes and identifies the image acquired by the industrial camera 51. This is existing technology, and the principle can be referenced in the invention patent CN110389133B, "System and Method for Identifying Vehicle Dirt," which includes an image acquisition device, an image processing device, a dirt identification device, and a dirt warning device. The image acquisition device is used to acquire images of the information acquisition module area on the vehicle; the image processing device is used to detect dirt in the images of the information acquisition module area; and the dirt identification device is used to identify dirt in the information acquisition module based on the dirt detection results. Alternatively, one can refer to the invention patent CN115520150B, "A Dynamic Dirt Identification Device for a Car Wash Robot," which will not be elaborated upon here.

[0036] In summary, the present invention provides a precision degreasing system for aluminum coil uncoiling operations that can simultaneously degrease and clean both sides of the aluminum coil 4. The identification unit 5 can accurately identify oil stains on the surface of the aluminum coil 4 and control the spraying unit 6 to perform targeted spraying, reducing the amount of degreasing agent used and avoiding waste and environmental pollution. At the same time, the wiping unit 7, combined with the spraying mechanism 74 and the squeegee 75, can effectively clean the wiping belt 73 and ensure the wiping effect.
