Technical Field
[0001] This invention belongs to the field of photovoltaic glass. Specifically, this invention relates to an automatic belt cleaning device for a photovoltaic glass coating machine. Background Technology
[0002] During the production of photovoltaic glass, impurities such as coating solution can easily remain on the surface of the coating machine belt. If not cleaned in time, this can affect the belt's service life. Furthermore, once the coating solution dries on the belt, it can form hard lumps or stains, further compromising the belt's flatness, increasing friction between the belt and the glass, potentially scratching the glass surface, and affecting the coating quality of the photovoltaic glass.
[0003] Currently, the mainstream cleaning methods are mostly manual wiping or simple mechanical cleaning, which suffer from low cleaning efficiency, incomplete cleaning, and high labor costs. Moreover, existing cleaning equipment often lacks the function of automatically spraying cleaning agents, making it difficult to effectively remove stubborn stains and failing to meet the automation and high-efficiency cleaning requirements of photovoltaic glass production.
[0004] Chinese patent application CN 105921473B, published on June 8, 2018, discloses a device for glass cleaning, comprising a frame, a conveyor, a CCD camera, a cleaning device, an air knife, and a controller. The frame has a wastewater tank at its base. The conveyor includes a drive wheel, a driven wheel, and a conveyor belt; the drive wheel is driven by a first motor. CCD cameras are evenly distributed at the inlet of the conveyor. The cleaning device includes a rinsing nozzle and multiple cleaning brush heads; the rinsing nozzle is mounted on the top of the frame and connected to a water tank via a water pipe and a water pump. The multiple cleaning brush heads are arranged parallel to each other in the direction of movement of the conveyor and are each connected to an automatic telescopic rod driven by a motor. An air knife is installed at the outlet of the conveyor. The controller is electrically connected to the CCD camera, the first motor, the water pump, the motor driving each automatic telescopic rod, and the air knife. However, this device for glass cleaning does not completely solve the aforementioned technical problems. Summary of the Invention

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.
[0020] like Figure 1 and Figure 2 As shown, the automatic belt cleaning device for a photovoltaic glass coating machine includes a frame 1 and a base 2. The base 2 is located on one side of the end of the frame 1. A flipping frame 3 is movably connected to the base 2. A slide rod 4 is fixedly connected to the top of the flipping frame 3. An mounting plate 5 is sleeved on the slide rod 4. A cleaning module is provided on the mounting plate 5. The cleaning module is located on one side of the belt end and is connected to a transmission mechanism.
[0021] This automatic belt cleaning device controls the movement of the sponge block 10 through a transmission mechanism. The reciprocating motion of the sponge block 10, combined with the spray system, ensures a more thorough cleaning of the belt, effectively extending its service life. It achieves automated cleaning of the photovoltaic glass coating machine belt, significantly reducing labor costs and improving production efficiency. The flipping frame 3 allows for flexible control of the contact between the cleaning module and the belt, without affecting the normal operation of the coating machine. The spray system uses isopropyl alcohol as the cleaning agent, which is highly targeted and provides excellent cleaning results. Furthermore, the spray volume can be adjusted by modifying the parameters of the peristaltic pump 15 as needed.
[0022] like Figure 1 and Figure 2 As shown, all components of the automatic cleaning device are fixed on the base 2, and the base 2 is located on one side of the end of the frame 1, not directly connected to the frame 1, which facilitates disassembly and maintenance, reduces equipment downtime, and can be directly installed on existing equipment without modification to clean the belt. It has high versatility, is simple and convenient to install, and occupies little space. The automatic cleaning device cleans the end of the belt and achieves cleaning of the entire belt surface through belt transmission. Its installation position is reasonable, does not occupy the space of the conveyor equipment when not in use, and does not need to be installed above or below the belt, making the layout simple and convenient.
[0023] like Figure 2As shown, there are two flipping frames 3, and a connecting rod 6 is fixedly connected between them. The transmission mechanism includes a motor 7, which is located at one end of the connecting rod 6. The output end of the motor 7 is connected to a turntable 8, and a connecting rod 9 is eccentrically connected to the turntable 8. The cleaning module includes a sponge block 10. The length of the mounting plate 5 is less than the length of the slide rod 4. The mounting plate 5 is fixedly connected to one side of the sponge block 10, and the end of the connecting rod 9 is hinged to the mounting plate 5. The cleaning sponge block 10 is fixedly connected to the mounting plate 5 and is used to directly wipe the surface of the belt. The motor 7 is fixedly mounted on the connecting rod 6, and its output shaft is fixed to the turntable 8, providing power for the left and right reciprocating motion of the cleaning module. The mounting plate 5 has a groove for the slide rod 4 to pass through, realizing a sliding connection with the two vertical parallel slide rods 4, so that the sponge block 10 fixed on the mounting plate 5 can move along the axial direction of the slide rod 4. The slide rods 4 are arranged vertically and parallelly to guide the movement of the mounting plate 5. The lengths of the mounting plate 5 and the sponge block 10 are shorter than the slide rods 4, ensuring that the sponge block 10 can reciprocate through the above structure. Turntable 8 is fixedly connected to the output shaft of motor 7. The edge of turntable 8 is hinged to one end of connecting rod 9, and the other end of connecting rod 9 is hinged to the back of mounting plate 5, thus forming a crank-slider structure. With the above structure, the power of motor 7 can be transmitted to sponge block 10 in sequence through turntable 8, connecting rod 9 and mounting plate 5. The rotational power output by motor 7 is converted to realize the reciprocating motion of sponge block 10 on slide rod 4. When sponge block 10 contacts the belt, it can apply a lateral force to the belt. The direction of the force is perpendicular to the conveying direction of the belt. Combined with the force generated when the sponge block 10 is pushed to contact the belt after being driven by cylinder 11, sponge block 10 can clean the belt evenly and thoroughly. At the same time, the movement of sponge block 10 in the conveying direction of the belt can remove hard lumps or stains adhering to the belt along both sides of the belt, reducing the accumulation of residue on sponge block 10, reducing the frequency of replacement or cleaning of sponge block 10, and reducing consumable costs. The above-mentioned motor 7 driving method is simple, occupies little space, is easy to arrange, and has low application cost.
[0024] like Figure 2 As shown, a support frame 19 is fixedly connected to the base 2. The flipping frame 3 is hinged to the top of the support frame 19. The flipping frame 3 has an L-shaped structure. A cylinder 11 is provided on one side of the support frame 19. The cylinder body of the cylinder 11 is hinged to the base 2, and the piston rod of the cylinder 11 is hinged to one end of the flipping frame 3. The cleaning module is fixed on the flipping frame 3, which is hinged to the support frame 19. The cylinder 11 is connected to the flipping frame 3. The rotation of the flipping frame 3 is controlled by the extension and retraction of the cylinder 11, thereby realizing the contact or separation of the cleaning module and the belt. The cylinder body and piston rod of the cylinder 11 are both hinged, which also allows the cylinder 11 to follow the rotation of the flipping frame 3, facilitating the unobstructed rotation of the flipping frame 3.
[0025] like Figure 2As shown, a front-end bracket 12 is provided on the base 2 on the other side of the support frame 19. Two front-end brackets 12 are vertically fixed to the base 2. The two front-end brackets 12 are located on either side of the belt end, and spray pipes 13 are connected to the top of each bracket. The spray pipes 13 are horizontally positioned, and nozzles 14 are evenly distributed at the bottom of each nozzle, with the open ends of the nozzles 14 facing downwards. The front-end brackets 12 are used to support the spray pipes 13. The spray pipes 13 are installed on the front-end brackets 12 of the base 2 and can be connected to a container holding isopropyl alcohol via a hose. A peristaltic pump 15, compatible with the coating machine, is used as a power source to introduce isopropyl alcohol from the container into the spray pipes 13, achieving spray cleaning of the belt. The multiple nozzles 14 increase the coverage of the isopropyl alcohol spray, allowing the sponge block 10 to evenly clean the belt using isopropyl alcohol. The bottom of the front-end bracket 12 has a T-shaped structure, improving its stability when fixed to the base 1.
[0026] like Figure 1 As shown, the end of the belt is located between the front support 12 and the tilting frame 3. With the above structure, during the operation of the device, the part of the belt that has not yet been wiped by the sponge block 10 is first evenly covered with isopropyl alcohol. Since the belt is running, it can then be wiped by the sponge block 10 in a timely manner. Hard lumps or stains can be thoroughly removed by the lateral reciprocating motion of the sponge block 10, while reducing the probability of isopropyl alcohol solution spilling due to the operation of the belt. This helps to reduce the amount of isopropyl alcohol solution used and reduce production consumable costs.
[0027] like Figure 2 As shown, there are two slide bars 4 arranged in parallel. The two slide bars 4 limit the movement of the sponge block 10, preventing the sponge block 10 from rotating relative to the slide bars 4, ensuring that the sponge block 10 can always be in contact with the end of the belt during operation, thus ensuring a uniform and reliable cleaning effect.
[0028] like Figure 1 As shown, a peristaltic pump 15 is provided on one side of the flip frame 3, and a peristaltic pump conduit 16 interface is provided on the top of the spray pipe 13. The peristaltic pump 15 provides power to the spray system, and the front bracket 12 on the base 2 supports the mounting bracket of the spray pipe 13. Isopropyl alcohol is introduced into the spray pipe 13 through the peristaltic pump 15. This layout and power source design realizes the automatic spraying of cleaning agent and improves the cleaning effect.
[0029] like Figure 1 and Figure 2 As shown, the base 2 has a fixing plate 17 at its bottom, and the fixing plate 17 has multiple fixing holes 18. The base 2 is used to fix the entire device. The fixing plate 17 is used to fix the whole device to the ground by using connectors, so that the whole device will not move relative to the frame 1 during operation, ensuring reliable cleaning effect, while also achieving the purpose of convenient disassembly, installation and maintenance, and ensuring the continuity of production.
[0030] like Figure 2 As shown, the bottom of the support frame 19 has an L-shaped structure, and the side of the support frame 19 is provided with reinforcing ribs 20. The above structure improves the structural strength of the support frame 19, ensuring stable support and operation for the tilting frame 3.
[0031] This automatic belt cleaning device for photovoltaic glass coating machines achieves stability and reliability of cleaning actions, automation and controllability of the cleaning process, and high-efficiency cleaning function through the transmission structure of the cleaning module, the linkage control of the flipping frame 3 and the cylinder 11, and the integrated design of the overall device. The transmission structure of the cleaning module: The cleaning module is connected by a combination of a sliding groove and a sliding rod 4, and hinged to the turntable 8 via a connecting rod 9. The motor 7 drives the turntable 8 to rotate, realizing the reciprocating motion of the cleaning block, ensuring the stability and reliability of the cleaning action; the linkage control of the flipping frame 3 and the cylinder 11: The flipping frame 3 is hinged to the support frame 19, and the flipping motion is controlled by the cylinder 11, realizing the precise contact and separation of the cleaning module and the belt. This control method ensures the automation and controllability of the cleaning process; the integrated design of the overall device: The integrated design of the cleaning module, flipping mechanism, spray system, and base 2 makes the device closely integrated with the coating machine, facilitating installation and use, while ensuring the high efficiency of the cleaning function.
[0032] The working process is as follows: Cylinder 11 is activated, causing the tilting frame 3 to rotate, bringing the sponge block 10 into contact with the end of the belt. When belt cleaning is required, cylinder 11 actuates, pushing the tilting frame 3 to rotate, ensuring the cleaning sponge block 10 adheres tightly to the belt surface. Motor 7 is activated, driving the turntable 8 to rotate. Since the turntable 8 is hinged to connecting rod 9, and the other end of connecting rod 9 is hinged to mounting plate 5, the cleaning sponge block 10 repeatedly wipes the belt left and right. Simultaneously, peristaltic pump 15 operates, spraying isopropyl alcohol onto the belt through spray pipe 13. Isopropyl alcohol acts as a cleaning agent, helping to remove residual coating solution from the belt. After cleaning, cylinder 11 reverses its direction, driving the tilting frame 3 to rotate, separating the cleaning module from the belt, allowing the belt to continue operating.
[0033] This automatic belt cleaning device for photovoltaic glass coating machines employs a cylinder-driven flipping mechanism, allowing the cleaning module to flexibly engage or disengage from the belt without affecting its normal operation. The motor-driven reciprocating motion of the cleaning module enables automated wiping of the belt, improving the uniformity and thoroughness of surface cleaning, ensuring belt flatness, and preventing friction between the belt and glass from affecting the coating quality of the photovoltaic glass. A spray system is also included, automatically spraying isopropyl alcohol to enhance the cleaning effect on coating solutions and other contaminants.
[0034] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
