[0013] Step 1: Place the single-sided photovoltaic glass through the cleaning box and place it on the internal conveying structure, which can be carried by the upper and lower symmetrical conveyor belts;

[0052] Working principle:

[0053] When processing single-sided photovoltaic glass:

[0054] The single-sided photovoltaic glass is placed through the conveying port 10 of the cleaning box 1 onto the internal conveying structure 7, which can be connected to other conveying equipment for conveying and can be carried and conveyed by means of the conveyor belt 76 between the conveying rollers 75 on the conveying frame 73;

[0055] When the conveyor belt 76 is used for carrying, the height of the conveyor belt 76 on the conveying frame 73 can be adjusted by means of the telescopic drive of the first hydraulic cylinder 72 on the base 71, and the second hydraulic cylinder 74 can be driven to telescopically adjust the height of the top conveyor belt 76 and the distance between the two conveyor belts 76, so that the conveyor belts 76 can be lowered to be opposite to the conveying port 10 at the bottom of the mouth, and the conveyor belts 76 can be divided into upper and lower layers to carry two pieces of photovoltaic glass; the upper and lower corresponding conveyor belts 76 can be relatively close to clamp a single piece of photovoltaic glass for conveying, and the glass can be moved out of the cleaning box 1 after entering the cleaning box 1;

[0056] That is, the first motor 77 is driven to drive one of the conveying rollers 75 to rotate through the connection between the first pulley 78 and the first transmission belt 79, so that the conveying belt 76 can rotate on the conveying roller 75 for conveying;

[0057] After the glass enters the cleaning box 1, the corresponding liquid pump 5 is driven to extract clean water to supply the internal spray structure 8. The spray structure 8 in the cleaning box 1 is equipped with a cleaning component 9;

[0058] That is, the liquid pump 5 supplies water to the shunt pipe 874, and the liquid flows into the spray pipe 872 in the swing frame 871 in the spray unit 87 through the shunt pipe 874, and then sprays out through the spray box 86 with the help of the corresponding spray head 873; the spray head 873 in the cleaning box 1 sprays water onto the cleaning roller 92 supported by the roller frame 91, and the cleaning roller 92 is driven by the third motor 93, and rotates in conjunction with the second pulley 94 and the second transmission belt 95, so that the whole cleaning roller 92 is wetted, and the cleaning roller 92 is forced to rotate at the same time;

[0059] According to the amount of glass being transported, the third hydraulic cylinder 82 can be driven to extend and retract, and the height of the symmetrically arranged cleaning roller 92 can be adjusted. The height position of the cleaning roller 92 can also be adjusted by means of the second electric slide rail 83, so that the cleaning roller 92 is located on the upper wall of the glass and can fit relatively well during the glass transport. Then the sprayed water will also fall on the glass, and the wet cleaning roller 92 rotates to scrub and rinse.

[0060] If a single-sided glass is conveyed, a cleaning roller 92 can be placed above the glass for cleaning, and another cleaning roller 92 symmetrically arranged is located below the conveying port 10 and can be waiting for replacement. The replaced cleaning roller 92 can be rinsed with the help of the nozzle 873 to achieve self-cleaning, and the cleaning roller 92 in the process of cleaning can also be self-cleaned by contact with clean water during the spraying process, that is, during the spraying process of the nozzle 873, the third electric slide rail 877 can be driven to drive the driving frame 876 to move forward and backward, and through the active connection between the driving frame 876 and the transmission frame 875, multiple nozzles 872 are driven to swing synchronously in the swing frame 871 to promote the cleaning effect of the cleaning roller 92; to replace the cleaning roller 92, the third hydraulic cylinder 82 needs to be retracted and the second electric slide rail 83 needs to be driven to drive the corresponding spray box 86 and the cleaning assembly 9 to descend to the bottom of the conveyor belt 76 and to the right side of the conveying unit by means of the transfer rod 85, and the cleaning roller 92 can be moved to the left to the bottom of the conveyor belt 76 by means of the first electric slide rail 81, and the transfer rod 85 is driven to rotate by the third motor 93 to achieve replacement and reset;

[0061] If two glasses are transported, the cleaning rollers 92 can be adjusted to corresponding heights by means of the second electric slide rail 83 and the third hydraulic cylinder 82 to clean the two glasses at the same time;

[0062] If it is for double-sided photovoltaic glass, it is clamped and conveyed by means of the upper and lower symmetrical conveyor belts 76, and the same operating principle as above, the symmetrically arranged cleaning rollers 92 are respectively placed at the corresponding heights on the upper and lower sides of the glass to achieve double-sided synchronous cleaning;

[0063] The cleaned glass will enter the air-drying box 2 with the help of the conveying structure 7, and will be moved through the air-drying box 2 with the help of the conveying structure 7 according to the same principle. During the movement of the glass in the air-drying box 2, the glass works in the same way as in the cleaning box 1, and the wind is driven by the air pump 6 to transmit the wind force to the spraying structure 8. Different spraying heads 873 are used to achieve different spraying effects. The wind force can be blown out directly through the spray box 86 to act on the glass for air-drying. Similarly, one piece of single-sided glass can be air-dried or two pieces can be air-dried simultaneously, and double-sided glass can also be air-dried simultaneously. The spray head 873 of the spray unit 87 can swing back and forth to improve the air-drying effect. A cleaning component 9 can also be added to absorb water and wipe it with the help of the cleaning roller 92, and air-dry it to a certain extent during the rotation process, and air-dry it with the help of the wind from the spray head 873. If a cleaning roller 92 is installed, the air blowing from the spray head 873 will also dry the cleaning roller 92 after absorbing water.

[0064] After the glass enters the spray box 3 from the air drying box 2 with the help of the conveying structure 7, the spray coating material is provided to the spray structure 8 with the help of the liquid pump 5, and spraying is also carried out with the help of different nozzles 873 to achieve a spray coating effect on the glass surface. The spray structure 8 in the spray box 3 does not need to be equipped with a cleaning component 9, and the coating in the spray box 3 is recommended to be used for single-sided glass coating to avoid one side of the double sides being affected by contact with the conveyor belt 76.

[0065] The conveyor belts 76 on the upper and lower sides of the conveying structure 7 can also be lifted and moved to fit the conveying port 10 to carry one photovoltaic glass respectively, that is, two photovoltaic glasses enter the cleaning box 1 respectively and then move through the conveying interface to the air drying box 2 with the help of the conveyor belts 76; during the use of the equipment, the valve 4 can be used to connect the pipeline for drainage.

[0066] Principle summary: The same box is divided into a cleaning box 1, an air drying box 2 and a spraying box 3, and the same conveying structure 7 is used to convey and carry the glass, which can be used for a single piece of single-sided glass, two single-sided glasses or a double-sided glass;

[0067] And cooperate with the spray structure 8, with the help of the symmetrically arranged spray unit 87, single-sided and double-sided cleaning can be achieved, and with the help of the difference between the liquid pump 5 and the air pump 6, clean water, wind power and spray material are respectively supplied in the cleaning box 1, the air drying box 2 and the spray box 3, and the nozzle 873 in the spray unit 87 is replaced accordingly;

[0068] Finally, with the help of the added cleaning components, efficient cleaning effect and self-cleaning function, efficient wiping and air-drying effect and self-cleaning air-drying function as well as oscillating spraying are achieved in the cleaning box 1, air-drying box 2 and spraying box 3 respectively for more uniform coating.
