Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a cleaning device for the production of coated photovoltaic glass. Background Technology

[0002] Photovoltaic glass, also known as "photovoltaic glass," is a special type of glass that generates electricity using solar radiation and includes related current extraction devices and cables. During the production of coated photovoltaic glass, dust, oil, and other contaminants remaining on the glass surface directly affect the coating quality; therefore, the cleaning process is crucial.

[0003] Existing photovoltaic glass cleaning devices can only clean one side of the photovoltaic glass. Cleaning the other side requires flipping the photovoltaic glass, which increases the operation steps and production time. It is also easy to damage the photovoltaic glass during the flipping process, and it is difficult to ensure the consistency of the cleaning effect on both sides. Although some cleaning devices can achieve double-sided cleaning, the cleaning method is relatively simple, usually just simple water spraying or brushing. Water spraying alone is not effective in removing some stubborn dirt. Brushing alone, if there is no timely water flow to rinse during the brushing process, the dirt brushed off will still adhere to the surface of the photovoltaic glass, which cannot achieve the ideal cleaning effect. Therefore, a cleaning device for the production of coated photovoltaic glass is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device for the production of coated photovoltaic glass, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device for the production of coated photovoltaic glass, comprising a roller conveyor for conveying photovoltaic glass before coating, a water tank on one side of the roller conveyor, a cleaning component for cleaning photovoltaic glass on one side of the water tank, and a filter component inside the water tank;

[0006] The cleaning assembly includes a protective cover and a connecting frame. Two rotating shafts are rotatably connected to the inner wall of the connecting frame. Rotating rollers are fixedly sleeved on the outer side of the rotating shafts. Several brush bristles are fixedly inserted into the outer side of the rotating rollers. The brush bristles are used to brush away dirt from the surface of the photovoltaic glass.

[0007] The rotating roller has several water spray holes on one side of the bristles, which spray water to wash away dirt from the surface of the photovoltaic glass.

[0008] A motor is fixed to the inner wall of the protective cover, and a first gear and a second gear are respectively fixed to the ends of the two rotating shafts away from the rotating roller.

[0009] Preferably, the first gear and the second gear are meshed together, and the output shaft of the motor is fixed to one side of the shaft center of the second gear.

[0010] Preferably, the connecting frame is fixed to one side of the connecting frame, and the supporting frame has a water storage cavity inside.

[0011] Preferably, the rotating shaft has a water delivery groove inside, which is connected to the water storage chamber and the spray hole respectively.

[0012] Preferably, as described above, a water pump is installed at the bottom of the inner wall of the water tank, and a flexible hose is connected to the outlet of the water pump, with the outlet of the flexible hose connected to the water storage chamber.

[0013] Preferably, the roller conveyor is of two type, which are used for feeding and discharging photovoltaic glass respectively. Two air knives are fixed on one side of each roller conveyor. One end of each air knife is connected to an air inlet pipe. The air knife is located at the discharge end of the cleaning component and is used to dry residual liquid on the surface of the photovoltaic glass.

[0014] Preferably, the filter assembly includes a cover plate, a filter screen is fixed to one side of the cover plate, a limiting bracket is fixed to the inner wall of the water tank, an insertion slot is provided on one side of the water tank located on one side of the limiting bracket, and the filter screen is sealed to the top of the limiting bracket.

[0015] Preferably, the cover plate is connected to one side of the water tank by bolts, the protective cover is fixed to one side of the connecting frame, the bottom of the connecting frame is fixed to the top of the water tank, and baffles are connected to both sides of the connecting frame.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0017] 1. The motor drives the second gear to rotate, which in turn connects the first and second gears, causing the two rotating rollers to rotate the brush bristles. This allows for simultaneous brushing of both sides of the photovoltaic glass, effectively removing dirt from its surface. Water spray holes are located on the surface of the rotating rollers. A water pump in the water tank draws water, which is then transported through a hose to the water storage chamber inside the support frame. The water is then sprayed out from the spray holes through a water delivery channel connected to the water storage chamber and the spray holes, further rinsing the surface of the photovoltaic glass and removing dirt, thus improving the cleaning effect.

[0018] Second, the mixture of dirt and water entering the water tank is filtered by the filter assembly. The filter screen can intercept the dirt in the water flow, leaving relatively clean water in the water tank for continued circulation. This ensures the cleanliness of the recycled water and prevents dirt from re-adhering to the photovoltaic glass, affecting the cleaning effect. It also helps protect downstream equipment such as water pumps and extends their service life. When the filter screen accumulates a lot of dirt and needs cleaning, simply remove the bolt on one side of the cover plate, remove the cover plate, and the filter screen will be moved out of the insertion slot. The operation is simple and convenient, without complicated tools or cumbersome steps, and the filter screen can be cleaned quickly to ensure the normal operation of the filter assembly.

[0019] Third, after the photovoltaic glass is cleaned, compressed air is blown onto the photovoltaic glass surface at high speed using an air knife. This can quickly and effectively dry the residual liquid on the photovoltaic glass surface, preventing water stains and watermarks from being left on the glass surface, ensuring the cleanliness and dryness of the photovoltaic glass surface, thereby improving the overall cleaning quality.

[0029] Example

[0030] Please see Figure 1-5 This utility model provides a technical solution: a cleaning device for the production of coated photovoltaic glass, including a roller conveyor 1 for conveying photovoltaic glass before coating, which can periodically clean the rollers on the surface of the roller conveyor 1, and the rollers on the surface of the roller conveyor 1 are wrapped with a rubber layer to increase the friction between the rollers and the photovoltaic glass. A water tank 5 is provided on one side of the roller conveyor 1, a cleaning component 2 for cleaning photovoltaic glass is provided on one side of the water tank 5, and a filter component 3 is provided inside the water tank 5.

[0031] The cleaning component 2 includes a protective cover 21 and a connecting frame 212. The protective cover 21 has a hole on one side for heat dissipation of the motor 22. Two rotating shafts are rotatably connected to the inner wall of the connecting frame 212. A rotating roller 211 is fixedly sleeved on the outside of the rotating shaft. Several bristles 213 are fixedly inserted on the outside of the rotating roller 211. The bristles 213 are used to brush away dirt from the surface of the photovoltaic glass. The height of the lower rotating roller 211 is slightly lower than the conveying height of the roller conveyor 1. Several water spray holes 210 are opened on the surface of the rotating roller 211, located on one side of the bristles 213. The water spray holes 210 spray water to rinse the dirt from the surface of the photovoltaic glass. The two rotating rollers 211 drive the bristles 213 on the surface to rotate. The bristles 213 are soft to avoid scratching the glass. The two sides of the photovoltaic glass are cleaned. At the same time, the water spray holes 210 spray water to rinse the dirt from the surface of the photovoltaic glass. The dirt enters the inside of the water tank 5 with the water flow. The water spray holes 210 are evenly distributed on the surface of the rotating roller 211 and are arranged alternately with the bristles 213.

[0032] A motor 22 is fixed to the inner wall of the protective cover 21. A first gear 23 and a second gear 24 are respectively fixed to the ends of the two rotating shafts away from the rotating roller 211. The first gear 23 and the second gear 24 are meshed together. The output shaft end of the motor 22 is fixed to one side of the shaft center of the second gear 24. The rotation of the second gear 24 drives the first gear 23 to rotate, which in turn drives the two rotating shafts fixed to the first gear 23 and the second gear 24 to rotate.

[0033] A support frame 29 is fixed to one side of the connecting frame 212. The support frame 29 has a water storage chamber 28 inside. A water delivery channel 27 is opened inside the rotating shaft, connecting the water storage chamber 28 and the spray nozzle 210. A water pump 25 is installed at the bottom of the inner wall of the water tank 5. A hose 26 is connected to the outlet of the water pump 25, and the outlet of the hose 26 is connected to the water storage chamber 28. The water pump 25 draws water from the water tank 5 and delivers it to the water storage chamber 28 inside the support frame 29 through the hose 26. The water delivery channel 27 inside the rotating shaft connects to both the water storage chamber 28 and the spray nozzle 210. Water flows from the water storage chamber 28 through the water delivery channel 27 to the spray nozzle 210, where it sprays water to wash away dirt from the photovoltaic glass surface. The dirt then flows into the inside of the water tank 5.

[0034] There are two roller conveyors 1. The two roller conveyors 1 are used for feeding and discharging photovoltaic glass respectively. Two air knives 4 are fixed on one side of each roller conveyor 1. One end of the air knife 4 is connected to an air inlet pipe 7. The air knife 4 is located at the discharge end of the cleaning component 2. The air knife 4 is used to dry the residual liquid on the surface of the photovoltaic glass. The air outlet of the air knife 4 faces the surface of the photovoltaic glass and forms an angle of 30°-45° with the glass, and is 5-10cm away from the glass surface.

[0035] The filter assembly 3 includes a cover plate 31, with a filter screen 33 fixed to one side of the cover plate 31. A limiting bracket 34 is fixed to the inner wall of the water tank 5. An insertion slot 32 is provided on one side of the water tank 5, located on the side of the limiting bracket 34. The filter screen 33 is sealed and connected to the top of the limiting bracket 34. By removing the bolts on one side of the cover plate 31 and removing the cover plate 31, the filter screen 33 can be removed from the insertion slot 32, allowing for cleaning of the filter screen 33. The mixture of dirt and water entering the water tank 5 is filtered by the filter assembly 3. The limiting bracket 34 fixed to the inner wall of the water tank 5 provides support and positioning for the filter screen 33. A rubber sealing ring (not shown in the figure) is provided between the filter screen 33 and the limiting bracket 34. The filter screen 33 is sealed and connected to the top of the limiting bracket 34. When water flows through the filter screen 33, dirt is intercepted by the filter screen 33, and relatively clean water remains in the water tank 5 for continued recycling.

[0036] The cover plate 31 is connected to one side of the water tank 5 by bolts. The protective cover 21 is fixed to one side of the connecting frame 212. The bottom of the connecting frame 212 is fixed to the top of the water tank 5. Baffles 6 are connected to both sides of the connecting frame 212 to prevent water sprayed from the spray hole 210 from flying out.

[0037] In this embodiment, the roller conveyor 1 is a model SSX01 manufactured by Henan Dingnuo Smart Logistics Technology Co., Ltd., which has a power structure. Since the structure and operating principle of this model of roller conveyor 1 are existing technologies, their structure and operating principle will not be described in detail here.

[0038] Working principle: Two roller conveyors 1 are responsible for feeding and discharging photovoltaic glass respectively, and smoothly transport the photovoltaic glass to be cleaned before coating to the cleaning module 2.

[0039] The output shaft of motor 22 is fixed to one side of the shaft of second gear 24. The rotation of motor 22 drives the rotation of second gear 24. First gear 23 and second gear 24 are meshed together. The rotation of second gear 24 drives the rotation of first gear 23, which in turn drives the two rotating shafts fixed to first gear 23 and second gear 24 to rotate. Rotating roller 211 is fixedly sleeved on the outside of rotating shaft. Several bristles 213 are fixedly inserted on the outside of rotating roller 211. The two rotating rollers 211 drive the bristles 213 on the surface to rotate, brushing and cleaning both sides of photovoltaic glass to remove dirt from the surface of photovoltaic glass.

[0040] The rotating roller 211 has several water spray holes 210 located on one side of the bristles 213. The water pump 25 installed at the bottom of the inner wall of the water tank 5 is started, and the water pump 25 draws water from the water tank 5 and delivers the water to the water storage chamber 28 inside the support frame 29 through the hose 26 connected to the water outlet. The rotating shaft has a water delivery channel 27, which is connected to the water storage chamber 28 and the water spray holes 210 respectively. Water flows from the water storage chamber 28 through the water delivery channel 27 to the water spray holes 210. The water spray holes 210 spray water to wash away the dirt on the surface of the photovoltaic glass. The dirt enters the inside of the water tank 5 with the water flow.

[0041] The mixture of dirt and water that enters the water tank 5 is filtered by the filter assembly 3. The limiting frame 34 fixed to the inner wall of the water tank 5 supports and positions the filter screen 33. The filter screen 33 is sealed to the top of the limiting frame 34. When the water flows through the filter screen 33, the dirt is intercepted by the filter screen 33, and the relatively clean water remains in the water tank 5 for continued recycling.

[0042] When a lot of dirt accumulates on the filter screen 33 and needs to be cleaned, remove the bolt on one side of the cover plate 31, remove the cover plate 31 to move the filter screen 33 away from the insertion slot 32, and then clean the filter screen 33. After cleaning, reinstall the filter screen 33 back into its original position through the cover plate 31.

[0043] After the photovoltaic glass is cleaned, it is transported to the discharge end by the roller conveyor 1. At this time, the air knife 4 located at the discharge end of the photovoltaic glass after cleaning is working. One end of the air knife 4 is connected to the air inlet pipe 7. External compressed air enters the air knife 4 through the air inlet pipe 7. The air knife 4 blows the compressed air to the surface of the photovoltaic glass in the form of a high-speed airflow to dry the liquid remaining on the surface of the photovoltaic glass.

[0044] In summary, the motor 22 drives the second gear 24 to rotate, and then the first gear 23 meshes with the second gear 24, causing the two rotating rollers 211 to drive the brush bristles 213 to rotate. This allows for simultaneous brushing of both sides of the photovoltaic glass, effectively removing dirt from the surface of the photovoltaic glass. Water spray holes 210 are opened on the surface of the rotating rollers 211. The water pump 25 in the water tank 5 draws water and delivers it through the hose 26 to the water storage chamber 28 inside the support frame 29. Then, through the water delivery channel 27 connected to the water storage chamber 28 and the water spray holes 210, water is sprayed out from the water spray holes 210 to rinse the surface of the photovoltaic glass, further removing dirt and improving the cleaning effect.

[0045] The mixture of dirt and water entering the water tank 5 is filtered by the filter assembly 3. The filter screen 33 can intercept the dirt in the water flow, allowing relatively clean water to remain in the water tank 5 for continued recycling. This ensures the cleanliness of the recycled water and prevents dirt from re-adhering to the photovoltaic glass, affecting the cleaning effect. It also helps protect subsequent equipment such as the water pump 25 and extends their service life. When a lot of dirt accumulates on the filter screen 33 and needs to be cleaned, simply remove the bolt on one side of the cover plate 31. Removing the cover plate 31 will allow the filter screen 33 to be moved out of the insertion slot 32. The operation is simple and convenient, requiring no complicated tools or cumbersome steps. The filter screen 33 can be cleaned quickly, ensuring the normal operation of the filter assembly 3.

[0046] After the photovoltaic glass is cleaned, compressed air is blown onto the photovoltaic glass surface at high speed using the air knife 4. This can quickly and effectively dry the residual liquid on the photovoltaic glass surface, preventing water stains and watermarks from being left on the glass surface, ensuring the cleanliness and dryness of the photovoltaic glass surface, thereby improving the overall cleaning quality.
