[0031] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0032] See also Figure 1-Figure 8 A photovoltaic coated glass cleaning device comprises two conveyor belts 1, which are arranged one in front of the other and used to convey the glass to be cleaned from the front side to the rear side. Two toothed belts 2 are arranged in parallel between the two conveyor belts 1. The inner top surface and the inner bottom surface of the toothed belt 2 are adjacent to each other up and down, and a gap is formed for the glass to pass through. A cleaning belt 3 for contact cleaning of the glass surface is detachably connected to the inner wall of the toothed belt 2. A driving component 1 is arranged on the left side of the two toothed belts 2. The driving component 1 is used to drive the two toothed belts 2 to rotate simultaneously but in opposite directions.

The interior of the water tank 4 is divided into an ultrasonic cleaning tank 401 and two cleaning liquid tanks 402, an ultrasonic generator is provided in the ultrasonic cleaning tank 401, the two cleaning liquid tanks 402 are respectively located on the left and right sides of the ultrasonic cleaning tank 401, each toothed belt 2 has two bent ends on the right side, one bent end of the two toothed belts 2 is immersed in the ultrasonic cleaning tank 401, and the other bent ends of the two toothed belts 2 are respectively immersed in one of the two cleaning liquid tanks 402, a pointed cone block 6 and a driving component 2 are provided between the left and right sides of the two conveyor belts 1, and the driving component 2 is used to drive the pointed cone block 6 on the same side thereof to move along the glass conveying direction to open the toothed belt 2 and create space for the glass to pass through.

[0033] The driving component 1 includes a motor 1 501 and a bevel gear set 502. A fixing frame 505 is arranged on the left side of the two toothed belts 2. The motor 1 501 is mounted on the fixing frame 505. The bevel gear set 502 includes a driving bevel gear and two driven bevel gears. The driving bevel gear is meshed with the two driven bevel gears respectively, and the meshing directions are opposite. The driving bevel gear is connected to the output shaft of the motor 1 501 in a transmission manner. The two driven bevel gears are fixedly connected with a rotating shaft 1 503 and a rotating shaft 2 504 respectively, wherein the rotating axes of the rotating shaft 1 503 and the rotating shaft 2 504 are on the same straight line, and the two are independently rotatably connected to the fixing frame 505, and respectively serve as driving rollers of the two toothed belts 2.

[0034] Driving component 2 includes motor 2 701, synchronous pulley 702 and synchronous belt 703. The left and right sides of each conveyor belt 1 are rotatably connected to a synchronous pulley 702. The two synchronous pulleys 702 on the same side are connected with a synchronous belt 703 in a circumferential meshing manner. Two pointed cone blocks 6 are respectively fixedly connected to the two synchronous belts 703. Motor 2 701 is installed on the left and right sides of one conveyor belt 1. The output shafts of the two motors 2 701 are respectively connected to the synchronous pulley 702 on the same side of the conveyor belt 1. The maximum thickness of the pointed cone block 6 is greater than the thickness of the glass. When driven by driving component 2, the pointed cone block 6 moves in the gap between the toothed belt 2 at a speed slightly faster than the conveying speed of the glass.

[0035] A plunger pump 8 is installed on the outside of the water tank 4, and the bent end of one toothed belt 2 immersed in the ultrasonic cleaning tank 401 is transmission-connected with a transmission roller 201, the transmission roller 201 rotates through the water tank 4, and is transmission-connected with the driving shaft of the plunger pump 8, the liquid inlet of the plunger pump 8 is connected to the inside of the water tank 4 through an infusion tube, a filter barrel 9 is arranged on the outside of the water tank 4, the liquid outlet of the plunger pump 8 is connected to the liquid inlet end of the filter barrel 9 through an infusion tube, and the liquid outlet end of the filter barrel 9 is connected to the inside of the water tank 4 through an infusion tube.

[0036] A water pressing roller 10 is rotatably connected to the left and right sides of the top of the ultrasonic cleaning tank 401 , and the two water pressing rollers 10 are in conflict with the cleaning belts 3 on the two toothed belts 2 .

[0037] Two guide rods 11 are arranged in parallel on the left and right sides of the conveyor belt 1, and the guide rods 11 are used to guide the movement of the glass.

[0038] A strip-shaped air nozzle 12 is respectively arranged at the upper and lower parts of the rear conveyor belt 1 close to the toothed belt 2. The two strip-shaped air nozzles 12 are used to blow out airflow to dry the upper and lower surfaces of the cleaned glass respectively.

[0039] Working principle: When in use, the glass to be cleaned is placed on the front conveyor belt 1. As the front conveyor belt 1 continues to run, the glass is smoothly conveyed toward the rear conveyor belt 1 under the guidance of the guide rod 11.

[0040] When the glass is about to reach the front side of the toothed belt 2, the synchronous pulley 702 is driven to rotate by the motor 2 701, thereby driving the synchronous belt 703 and the pointed cone block 6 thereon to move into the interior of the toothed belt 2. During this process, since the maximum thickness of the pointed cone block 6 is greater than the thickness of the glass, the pointed cone block 6 will open the upper and lower sides of the toothed belt 2 to create space for the glass to enter the gap of the toothed belt 2, ensuring that the glass can smoothly enter the gap of the toothed belt 2. Since the moving speed of the pointed cone block 6 is slightly faster than the conveying speed of the glass, it is ensured that the glass can be surrounded by the cleaning belt 3 above and below after entering the gap of the toothed belt 2.

[0041] As the glass gradually enters the gap between the toothed belts 2 and is surrounded by the cleaning belt 3 from top to bottom, the main bevel gear is driven to rotate by the motor 501, and the main bevel gear drives the two driven bevel gears to rotate synchronously in the opposite direction. The rotation of the two driven bevel gears is transmitted to the two toothed belts 2 through the rotating shaft 1 503 and the rotating shaft 2 504 respectively, so that the two toothed belts 2 can rotate synchronously but in the opposite direction. The rotation of each toothed belt 2 will drive the cleaning belt 3 on its inner wall to clean the glass on both sides. The synchronous but opposite rotation of the two toothed belts 2 allows the two cleaning belts 3 to clean the glass surface synchronously but in the opposite direction. This two-way cleaning method can effectively enhance the cleaning effect and ensure that impurities on the surface of the photovoltaic coated glass are effectively removed.

[0042] After opening the gap of the toothed belt 2 for the first piece of glass, the pointed cone block 6 gradually moves to the side of the rear conveyor belt 1 along with the synchronous belt 703, and continues to move from the side of the rear conveyor belt 1 to the side of the front conveyor belt 1 under the continuous rotation of the synchronous belt 703, preparing to open the gap of the toothed belt 2 for the next glass to be cleaned. In this way, the glass can be continuously and efficiently cleaned on both sides by the cleaning belt 3, effectively reducing the accumulation of the conveying distance of the glass during the cleaning process, thereby significantly shortening the time of the cleaning process and improving the overall work efficiency and production output.

[0043] The cleaned glass will then contact the top of the rear conveyor belt 1, and continue to move backwards under the joint drive of the front and rear conveyor belts 1, and will eventually be completely transported by the rear conveyor belt 1 and output to the next process. During this process, the glass will pass between the two strip air nozzles 12, and the high-speed airflow blown out by the two strip air nozzles 12 will quickly dry the upper and lower surfaces of the glass.

[0044] Since the two toothed belts 2 rotate simultaneously but in opposite directions, the cleaning belts 3 on the two toothed belts 2 can pass through the ultrasonic cleaning tank 401 and the cleaning liquid tank 402 in sequence. When the cleaning belt 3 passes through the ultrasonic cleaning tank 401, the ultrasonic generator in the ultrasonic cleaning tank 401 generates ultrasonic vibration to peel off the dirt attached to the cleaning belt 3. Subsequently, the cleaning belt 3 continues to move and is squeezed by the water pressure roller 10 to remove excess water and residual dirt. Then, the cleaning belt 3 enters the cleaning liquid tank 402 and re-absorbs clean cleaning liquid. This process is repeated to ensure that the cleaning belt 3 always maintains a high-efficiency cleaning ability.

[0045] During the entire cleaning process, the driven roller of the toothed belt 2 can drive the plunger pump 8 to extract the liquid containing dirt in the ultrasonic cleaning tank 401 to the filter barrel 9 for filtering treatment. The filtered cleaning liquid returns to the ultrasonic cleaning tank 401 to form a closed-loop water circulation system, so that the water quality in the ultrasonic cleaning tank 401 is continuously cleaned, ensuring the cleaning effect of the cleaning belt 3 on the glass, and reducing water resource consumption, which is beneficial to environmental protection and sustainable development.
