Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass processing technology, and in particular to an adjustable photovoltaic glass coating spraying device. Background Technology

[0002] As a key component of solar photovoltaic modules, photovoltaic glass typically requires one or more functional coatings, such as anti-reflective films, self-cleaning layers, or conductive films, to improve photoelectric conversion efficiency, enhance environmental durability, or achieve specific electrical properties. The uniformity, thickness accuracy, and adhesion of these coatings have a crucial impact on the overall performance and lifespan of photovoltaic modules. Therefore, efficient and stable coating processes are a core technological aspect of photovoltaic manufacturing, and the performance of the spraying equipment, as an important piece of equipment for realizing this process, directly determines the quality of the coating and the level of automation in production.

[0003] Existing spraying devices (such as the automatic spraying device disclosed in utility model patent CN 217888385 U, which uses wheels to move along the edge of photovoltaic glass and drive a roller coating cloth ring for spraying) face prominent problems in practical applications, such as poor stability, easy damage to the substrate, and insufficient adaptability. The device uses wheels to move directly along the edge or surface of the photovoltaic glass to drive the entire spraying structure. Since the spraying device itself has a certain weight, it is easy to cause unstable walking trajectory due to vibration or deviation during the movement, which in turn causes quality defects such as uneven coating thickness, edge missed coating, or recoating.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need an adjustable spraying device for photovoltaic glass coating to solve this problem. This novel spraying device should avoid direct contact with the photovoltaic glass surface, significantly improving operational stability and coating uniformity. It should also possess good dimensional adjustment capabilities and anti-interference performance, better meeting the stringent requirements of modern photovoltaic manufacturing for high-precision, high-yield, and non-contact coating, thus providing strong support for the high-quality development of the photovoltaic industry. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable photovoltaic glass coating spraying device, which solves the problem in the prior art where the spraying device moves directly on the edge or surface of the photovoltaic glass using wheels to drive the entire spraying structure. Because the spraying device itself has a certain weight, it is easy for the movement trajectory to be unstable due to vibration or deviation during the movement, which in turn causes quality defects such as uneven coating thickness, missing coating at the edges, or recoating.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable photovoltaic glass coating spraying device includes a spraying base and a spraying groove formed on the top of the spraying base. A support plate is provided inside the spraying groove. The bottom of the support plate is connected to the bottom of the spraying groove through a horizontally moving structure. Adjustable clamping structures are provided on both sides of the top of the support plate.

[0008] The top of the spraying base is provided with several roller coating rings, which are connected to the top of the spraying base through a drive mechanism.

[0009] Preferably, the drive mechanism includes two mounting seats disposed at both ends of the roller coating ring. Both ends of the roller coating ring are rotatably connected to the mounting seats. Both mounting seats are fixedly connected to the top of the spray base by bolts. A drive module is installed on the side wall of one of the mounting seats, and the output shaft of the drive module is connected to the end of the roller coating ring.

[0010] Preferably, the adjustable clamping structure includes a clamping plate and a side plate. The bottom of the clamping plate is slidably connected to the top of the bearing plate, and the bottom of the side plate is fixedly connected to the top of the bearing plate. An adjusting screw with one end threaded through the side plate is provided on one side of the side plate, and one end of the adjusting screw is rotatably connected to the side wall of the clamping plate.

[0011] Preferably, a spray pipe is provided at the top of the roller coating ring, the two ends of the spray pipe are respectively connected to adjacent mounting bases, a number of vertical pipes are connected to the bottom of the spray pipe, a nozzle is connected to the bottom end of each vertical pipe, and a liquid supply pipe is connected to one side of the top of the spray pipe.

[0012] Preferably, the horizontal moving structure includes two mounting plates and a lead screw rotatably connected between the two mounting plates. The bottom of the mounting plate is connected to the inner bottom of the spray tank. A drive motor is mounted on the side wall of one side of the mounting plate. The output shaft of the drive motor is connected to the end of the lead screw. A bottom rod is fixedly connected to the bottom center of the bearing plate. The bottom rod is threadedly engaged with the lead screw.

[0013] Preferably, guide rods are provided on both sides of the lead screw, and both ends of the guide rods are connected to the mounting plate, and the bottom rod is in sliding engagement with the lead screw.

[0014] This invention offers the following advantages: The device, by fixing the coating roller ring to the top of the spraying base and driving its rotation via a drive mechanism, allows the photovoltaic glass to move via a support plate and a horizontal moving structure. This fundamentally changes the existing technology's reliance on wheels to move the entire spraying device across the glass surface, avoiding direct contact and continuous pressure between the spraying equipment and the photovoltaic glass surface. This effectively prevents physical damage such as scratches, indentations, or micro-cracks on the glass surface caused by the equipment's weight, significantly improving product surface quality and yield. Furthermore, because the coating roller ring is fixed in position and coating is performed solely through rotation, while the movement of the photovoltaic glass is precisely controlled by the bottom horizontal moving structure, this invention achieves superior performance. The design ensures smoother relative movement during the coating process, reducing trajectory instability caused by equipment vibration or movement deviation. This improves coating uniformity and thickness consistency, and reduces defects such as missed coatings and recoatings. Furthermore, the adjustable clamping structure on the support plate can accommodate photovoltaic glass of different widths, enhancing the equipment's compatibility and adjustment flexibility for various product specifications, meeting the flexible and multi-variety processing needs of actual production. The overall structure separates the coating action from the movement action, achieving a non-contact, highly stable coating method. This not only improves coating accuracy and operational reliability but also reduces mechanical wear and maintenance costs during equipment operation. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, an adjustable photovoltaic glass coating spraying device of this embodiment includes a spraying base 1 and a spraying groove 2 opened on the top of the spraying base 1. A support plate 4 is provided inside the spraying groove 2. The bottom of the support plate 4 is connected to the bottom of the spraying groove 2 through a horizontal moving structure. Adjustable clamping structures are provided on both sides of the top of the support plate 4.

[0025] The top of the spray base 1 is provided with several roller coating rings 3, which are connected to the top of the spray base 1 through a drive mechanism.

[0026] Workflow: When using this adjustable photovoltaic glass coating spraying device, the photovoltaic glass 5 to be coated is first placed on top of the support plate 4. The sides of the photovoltaic glass are clamped and fixed by the adjustable clamping structures on both sides of the support plate 4 to ensure that its position is stable and does not shift during the coating process. The support plate 4 is connected to the bottom of the spraying tank 2 through the horizontal moving structure at the bottom. After clamping, the horizontal moving structure is activated, which drives the support plate 4 and the photovoltaic glass on it to move smoothly back and forth along the length of the spraying tank 2. At the same time, several roller coating rings 3 set on the top of the spraying base 1 are driven to rotate by the drive mechanism. During the rotation, the roller coating rings 3 come into contact with and absorb the coating liquid flowing on their surface. As the carrier plate 4 drives the photovoltaic glass to move continuously below the roller coating ring 3, the rotating roller coating ring 3 evenly transfers and coats the coating liquid onto the upper surface of the photovoltaic glass 5. During the entire coating process, the roller coating ring 3 itself is fixed on the spray base 1 and does not move with the photovoltaic glass. It only completes the coating action by rotating. The movement of the photovoltaic glass is precisely controlled by the carrier plate 4 and the horizontal moving structure, thereby achieving a non-contact and stable coating operation. After a single coating stroke is completed, it can be repeatedly moved back and forth according to process requirements to achieve multi-layer or thicker coating. After the coating is completed, the drive mechanism and the horizontal moving structure are turned off, the adjustable clamping structure is released, and the coated photovoltaic glass is removed from the carrier plate 4, completing the entire coating process.

[0027] Example 2

[0028] Please see Figure 1-5 As shown in this embodiment, an adjustable photovoltaic glass coating spraying device includes a drive mechanism comprising two mounting seats 6 disposed at both ends of a roller coating ring 3. Both ends of the roller coating ring 3 are rotatably connected to the mounting seats 6, and both mounting seats 6 are bolted to the top of the spraying base 1. A drive module is mounted on the side wall of one of the mounting seats 6, and the output shaft of the drive module is connected to the end of the roller coating ring 3. Specifically, through the connection of the mounting seats 6, the drive module, and the end of the roller coating ring 3, the two mounting seats 6 are respectively fixed to the top of the spraying base 1 and form a rotational support for both ends of the roller coating ring 3. The drive module is mounted on the side wall of one of the mounting seats 6, and its output shaft is connected to the end of the roller coating ring 3. When the drive module is started, it drives the roller coating ring 3 to rotate around its own axis through the output shaft, realizing the stable rotation and power supply of the roller coating ring 3. This achieves the effect of providing reliable power input to the roller coating ring 3, ensuring its continuous and uniform rotation to stably transfer the coating liquid, and improving the continuity and consistency of the coating process.

[0029] A spray pipe 7 is provided at the top of the roller coating ring 3. The two ends of the spray pipe 7 are connected to the adjacent mounting bases 6 respectively. Several vertical pipes 8 are connected to the bottom of the spray pipe 7. Each vertical pipe 8 is connected to a nozzle at its bottom end. A liquid supply pipe 9 is connected to one side of the top of the spray pipe 7. Specifically, through the connection of the spray pipe 7, vertical pipes 8, nozzles, and liquid supply pipe 9 to the mounting bases 6, the spray pipe 7 spans across the roller coating ring 3 and is supported and fixed by the mounting bases 6 at both ends. The liquid supply pipe 9 is connected to an external paint supply system and guides the paint into the spray pipe 7. The paint is diverted through the spray pipe 7 to multiple vertical pipes 8, and then evenly sprayed onto the outer surface of the roller coating ring 3 by the nozzles at the bottom of the vertical pipes 8. This allows the roller coating ring 3 to continuously and evenly absorb paint during rotation, achieving a stable and uniform paint supply for the roller coating ring 3, avoiding local paint shortages or accumulation, and ensuring consistent coating quality.

[0030] Example 3

[0031] Please see Figure 1-5 As shown in this embodiment, an adjustable photovoltaic glass coating spraying device includes an adjustable clamping structure comprising a clamping plate 13 and a side plate 11. The bottom of the clamping plate 13 is slidably connected to the top of the support plate 4, and the bottom of the side plate 11 is fixedly connected to the top of the support plate 4. An adjusting screw 12 with one end threaded through the side plate 11 is provided on one side of the side plate 11. One end of the adjusting screw 12 is rotatably connected to the side wall of the clamping plate 13. Specifically, through the clamping plate 13, the side plate 11, the adjusting screw 12, and the sliding connection structure on the support plate 4, the device effectively clamps... Plate 13 can slide along the top of the support plate 4. Side plate 11 is fixed on the support plate 4. One end of adjusting screw 12 is threaded through side plate 11 and rotatably connected to it, and the other end is rotatably connected to the side wall of clamping plate 13. When it is necessary to clamp photovoltaic glass 5 of different widths, rotating adjusting screw 12 will push clamping plate 13 to slide along support plate 4 through thread transmission, thereby adjusting the distance between clamping plate 13 and the opposite side structure. This achieves adaptive clamping of photovoltaic glass 5 of different sizes, and achieves the effect of flexibly adjusting clamping width, improving equipment versatility and clamping adaptability.

[0032] The horizontal moving structure includes two mounting plates 15 and a lead screw 17 rotatably connected between the two mounting plates 15. The bottom of the mounting plates 15 is connected to the inner bottom of the spray tank 2. A drive motor 14 is mounted on the side wall of one side of the mounting plate 15. The output shaft of the drive motor 14 is connected to the end of the lead screw 17. A bottom rod 10 is fixedly connected to the bottom center of the bearing plate 4. The bottom rod 10 is threadedly engaged with the lead screw 17. Specifically, through the mounting plates 15, drive motor 14, lead screw 17, and the threaded engagement of the bottom rod 10 and lead screw 17, the two mounting plates 15 are fixed in the spray tank. 2. At the bottom, the two ends of the lead screw 17 are rotatably connected between the mounting plates 15. The drive motor 14 is mounted on the side wall of the mounting plate 15, and its output shaft is connected to the end of the lead screw 17. The bottom rod 10 at the bottom of the bearing plate 4 is threadedly engaged with the lead screw 17. When the drive motor 14 starts, it drives the lead screw 17 to rotate. Through the threaded transmission, the bottom rod 10 moves along the axial direction of the lead screw 17, thereby driving the entire bearing plate 4 to make reciprocating linear motion in the spray tank 2. This achieves precise control of the moving speed and stroke of the photovoltaic glass 5, realizes stable and adjustable horizontal conveying, and ensures a continuous and uniform coating process.

[0033] Guide rods 16 are provided on both sides of the lead screw 17. Both ends of the guide rods 16 are connected to the mounting plate 15. The bottom rod 10 is slidably engaged with the lead screw 17. Specifically, through the slidable engagement of the guide rods 16 with the mounting plate 15 and the bottom rod 10, the guide rods 16 are set parallel to the lead screw 17 on both sides, and both ends are fixedly connected between the two mounting plates 15. The bottom rod 10 is provided with sliding holes that match the guide rods 16. When the lead screw 17 drives the bottom rod 10 to move, the guide rods 16 provide guidance and support for the bottom rod 10, restrict its rotation and ensure that it moves smoothly along a straight line. This achieves the effect of enhancing the guiding stability of the bearing plate 4 during the movement process, preventing shaking or displacement caused by off-center load or vibration, and further improving the coating accuracy and operational reliability.

[0034] When using the adjustable photovoltaic glass 5 coating spraying device, the photovoltaic glass 5 to be coated is first placed on the top of the support plate 4. By rotating the adjusting screw 12, the screw is threaded with the side plate 11 and rotated with the clamping plate 13, pushing the clamping plate 13 to slide along the top of the support plate 4, thereby adjusting the distance between the two clamping plates 13 to clamp and fix photovoltaic glass 5 of different widths, ensuring that its position is stable and does not shift during the subsequent coating process. After clamping, the drive motor 14 is started, and its output shaft drives the lead screw 17 to rotate between the two mounting plates 15. Since the bottom rod 10 at the bottom of the support plate 4 and the screw 17 rotate between the two mounting plates 15, the screw 17 rotates between the two mounting plates 15. The lead screw 17 is threaded, and its rotation is converted into linear motion of the bottom rod 10 along its axial direction. This drives the support plate 4 and the photovoltaic glass 5 on it to move smoothly back and forth along the length of the spraying tank 2. At the same time, the guide rods 16 on both sides of the lead screw 17 are fixedly connected to the mounting plate 15 at both ends. The bottom rod 10 and the guide rods 16 are slidably engaged, providing additional guidance and support during the movement, effectively preventing the support plate 4 from deflecting or shaking during the movement, and ensuring the straightness and stability of the movement trajectory. Meanwhile, the external coating supply system delivers the coating liquid to the spray pipe 7 through the liquid supply pipe 9. The spray pipe 7 spans over the roller coating cloth ring 3 and... Supported and fixed by mounting bases 6 at both ends, the coating liquid is diverted through spray pipes 7 to multiple vertical pipes 8, and evenly sprayed onto the outer surface of the roller coating ring 3 through nozzles at the bottom of the vertical pipes 8. The two ends of the roller coating ring 3 are mounted on the mounting bases 6 by a rotating connection. After the drive module on the side wall of one mounting base 6 is started, its output shaft drives the roller coating ring 3 to rotate continuously around its own axis, so that the roller coating ring 3 evenly absorbs the coating liquid from the nozzles during the rotation. As the carrier plate 4 moves the photovoltaic glass 5 continuously below the roller coating ring 3, the rotating roller coating ring 3 evenly transfers and coats the absorbed coating liquid onto the upper surface of the photovoltaic glass 5, achieving non-contact stabilization. Coating operation: Throughout the process, the coating roller 3 is fixed on the spray base 1 and does not move with the photovoltaic glass 5. It only completes the coating action by rotating. The movement of the photovoltaic glass 5 is precisely controlled by a horizontal movement structure consisting of the lead screw 17, drive motor 14, bottom rod 10 and guide rod 16. After a single coating stroke is completed, it can be repeatedly moved back and forth according to process requirements to achieve multi-layer or thicker coating. After the coating is completed, the drive motor 14 and drive module are turned off, the movement of the lead screw 17 and the coating roller 3 is stopped, the adjusting screw 12 is rotated in the opposite direction to loosen the clamping plate 13, and the coated photovoltaic glass 5 is removed from the carrier plate 4 to complete the entire coating process.This device, by fixing the coating roller ring 3 to the top of the spray base 1 and driving its rotation via the mounting base 6 and drive module, avoids the method of the existing spraying device directly moving on the surface of the photovoltaic glass 5. This fundamentally eliminates the squeezing and friction damage to the glass surface caused by the weight of the equipment, effectively preventing physical defects such as scratches and indentations, and significantly improving product surface quality and yield. The fixed position of the coating roller ring 3, powered by an independent drive module, ensures smooth operation. Combined with the uniform liquid supply system consisting of the spray pipe 7, vertical pipe 8, nozzle, and liquid supply pipe 9, it ensures continuous and uniform distribution of the coating liquid on the surface of the coating roller ring 3, avoiding localized accumulation or shortage of coating, and improving... The uniformity and consistency of the coating are improved; the support plate 4 moves through the threaded engagement of the bottom rod 10 and the lead screw 17, and with the guidance of the guide rod 16, the movement of the photovoltaic glass 5 is more stable and precise, reducing the problem of uneven coating caused by vibration or offset, and improving the coating accuracy; the clamping plate 13, side plate 11 and adjusting screw 12 in the adjustable clamping structure work together to flexibly adapt to different specifications of photovoltaic glass 5, enhancing the versatility and production flexibility of the equipment; all structures are integrated into the spraying base 1 and spraying tank 2, with a reasonable layout and reliable operation, which not only improves the coating efficiency and quality stability, but also reduces the difficulty of equipment maintenance and the risk of operation.
