Description

Technical Field

[0001] This application relates to the technical field of coating spraying apparatus, and in particular to nano-coating spraying apparatus. Background Technology

[0002] As a crucial component of renewable energy, the surface treatment technology of photovoltaic panels directly impacts photoelectric conversion efficiency and lifespan. In recent years, nano-coating technology has gradually become a research hotspot in photovoltaic panel surface treatment due to its excellent anti-reflection, self-cleaning, and weather-resistant properties.

[0003] Currently, the application of nano-coatings on photovoltaic panels mainly employs manual spraying or stationary automated spraying equipment. Manual spraying relies on operators holding spray guns, while stationary automated spraying equipment typically uses a gantry structure, allowing the nozzles to move along guide rails for unidirectional spraying. Some high-end equipment incorporates robotic arms for multi-angle spraying, but linear spraying remains the primary method.

[0004] However, in existing spraying technologies, the amount of paint sprayed from the nozzle gradually decreases as it moves away from the nozzle center. Currently, manual spraying or fixed unidirectional spraying easily leads to uneven coating thickness. The coating uniformity is mainly achieved by reducing the nozzle spacing, but the thickness at the nozzle is still slightly thicker than in other areas, resulting in uneven coating thickness and spraying streaks, which ultimately reduces the uniformity of coating thickness. Utility Model Content

[0005] To improve the uniformity of coating thickness, this application provides a nano-coating spraying device.

[0006] The nano-coating spraying device provided in this application adopts the following technical solution: A nano-coating spraying device includes a robot body, a moving mechanism, a spraying mechanism, and a leveling mechanism. The robot body is mounted on a photovoltaic panel. The moving mechanism is mounted on the robot body and used to move the robot body along the photovoltaic panel. The spraying mechanism is mounted on the robot body and used to spray a nano-layer onto the surface of the photovoltaic panel. The leveling mechanism is mounted on the robot body and used to level the sprayed nano-layer. The spraying mechanism includes: A swing bar, wherein the swing bar is slidably disposed on the robot body and the sliding direction is perpendicular to the moving direction of the robot body; The nozzles, in multiple sets, are spaced apart on the swing bar and used to spray nano-coating onto the photovoltaic panel; A drive assembly is mounted on the robot body and is used to drive the swing bar to reciprocate and slide.

[0007] By adopting the above technical solution, the moving mechanism drives the robot body to move on the photovoltaic panel, while the driving component drives the swing bar to swing back and forth, and causes multiple sets of nozzles to spray out a wave-shaped spraying trajectory. Finally, the scraping mechanism scrapes the sprayed nano-layer to eliminate the unevenness of the coating thickness and the spraying streaks, thereby improving the uniformity of the coating thickness.

[0008] Furthermore, the driving component includes: A rotating disk is rotatably mounted on the robot body. A drive shaft, which is eccentrically mounted on the rotary disk; A sliding yoke is slidably mounted on the robot body along the swing direction of the swing bar; a groove perpendicular to the sliding direction is provided on the sliding yoke, one end of the drive shaft is slidably mounted in the groove along the length of the groove, the sliding yoke is connected to the swing bar, and when the rotary disk rotates, it drives the drive shaft to slide in the groove and drives the sliding yoke to slide back and forth. A rotary motor is mounted on the robot body and is used to drive the rotating disk to rotate.

[0009] By adopting the above technical solution, the rotary motor drives the rotary disk to rotate, which in turn drives the sliding yoke to swing back and forth through the eccentric drive shaft. The sliding yoke drives the swing bar to swing back and forth, thereby converting the rotational motion into linear reciprocating motion and ensuring that the swing bar obtains a stable reciprocating motion trajectory.

[0010] Furthermore, the leveling mechanism includes: A support block is mounted on the robot body, and a sliding groove is provided on the side of the support block near the photovoltaic panel; A sliding block is slidably disposed in a sliding groove, and a limiting ring is provided on the support block to prevent the sliding block from sliding out of the sliding groove; A scraper, which is mounted on a sliding block and used to smooth the sprayed nano-layer; A damper, wherein the fixed end of the damper is disposed on the bottom of the sliding groove, and the movable end of the damper is disposed on the sliding block; A first compression spring is sleeved on the damper and its two ends are respectively pressed against the sliding groove and the sliding block. The first compression spring is used to push the sliding block to slide away from the bottom of the sliding groove. The second compression spring is disposed between the limiting ring and the sliding block. The second compression spring is used to push the sliding block to slide towards the bottom of the sliding groove. The first compression spring and the second compression spring together push the sliding block to slide.

[0011] By adopting the above technical solution, the first compression spring and the second compression spring together balance the sliding block in the sliding groove, while the damper absorbs vibration and prevents the scraper from jumping, so that the scraper is stably set on the robot body, making it easier to scrape the coating.

[0012] Furthermore, the support block is provided with an adjustment assembly for adjusting the initial pressure values ​​of the first compression spring and the second compression spring, the adjustment assembly comprising: An adjusting plate is slidably disposed on one side of the bottom of a sliding groove. The adjusting plate has a through hole for the damper to pass through. The two ends of the first compression spring are respectively pressed against the adjusting plate and the sliding block. A telescopic component is provided on the support block and is used to push the adjustment plate to slide towards or away from the sliding block.

[0013] By adopting the above technical solution, the telescopic component slides with the adjustment plate, thereby changing the initial compression of the first and second compression springs, and finally achieving the adjustment of the initial pressure of the scraper.

[0014] Furthermore, the support block is provided with an observation window for easy observation of the position of the adjustment plate. The observation window is made of transparent material and has scale lines for easy measurement of the distance between the adjustment plate and the sliding block, and between the sliding block and the limiting ring.

[0015] By adopting the above technical solution, when adjusting the position of the adjusting plate, the position between the sliding block and the adjusting plate is measured through the observation window and scale lines, thereby realizing the visual adjustment of the compression amount of the first compression spring and the second compression spring.

[0016] Furthermore, the moving mechanism includes: Guide rails, two of which are laid along opposite edges of the photovoltaic panel; The walking wheels are mounted on one end of the robot body and rotatably connected to one of the guide rails. A driven wheel is mounted on the end of the robot body away from the walking wheels, and the driven wheel is rotatably connected to another set of guide rails; A drive motor is mounted on the robot body and is used to drive the walking wheels to rotate.

[0017] By adopting the above technical solution, the drive motor drives the walking wheels to roll on the guide rail, and then the robot body drives the driven wheels to roll on another set of guide rails, thereby reducing the deviation when the robot body moves in a straight line.

[0018] Furthermore, the sliding yoke is located in the middle of the swing bar, and the sliding yoke and the swing bar are detachably connected by a connecting frame.

[0019] By adopting the above technical solution, the swing bar can be detachably installed on the sliding yoke via the connecting frame, thereby facilitating the replacement of the swing bar.

[0020] Furthermore, both the sliding block and the limiting ring are provided with positioning grooves to facilitate the positioning of the second compression spring.

[0021] By adopting the above technical solution, the position of the second compression spring is positioned by the positioning groove, reducing the probability of the second compression spring deflection and ensuring the linearity of pressure transmission.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive motor rotates the walking wheels and, in conjunction with the driven wheels, enables the robot body to move stably on the guide rail of the photovoltaic panel. At the same time, the rotary motor drives the rotating disk to rotate, which in turn drives the sliding yoke to reciprocate through the eccentrically set drive shaft. This ultimately drives multiple sets of nozzles on the swing bar to uniformly spray the nano-coating along a curved trajectory. Subsequently, under the synergistic action of the first and second compression springs, the scraper uses constant pressure to dehumidify and smooth the coating, eliminating uneven thickness and spraying streaks, and ultimately improving the uniformity of the coating thickness.

[0023] 2. The adjusting plate is slidable by the telescopic component to adjust the initial pressure values ​​of the first and second compression springs. The positions of the sliding block and adjusting block are then accurately read through the observation window and scale lines, facilitating the measurement of the force exerted by the first and second compression springs on the sliding block.

[0025] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0026] This application discloses a nano-coating spraying device.

[0027] Example 1 Reference Figure 1 and Figure 2 The nano-coating spraying device includes a robot body 1, a moving mechanism 2, a spraying mechanism 3, and a leveling mechanism 4. The robot body 1 is mounted on a photovoltaic panel. The moving mechanism 2 is mounted on the robot body 1 and is used to drive the robot body 1 to move along the photovoltaic panel. The spraying mechanism 3 is mounted on the robot body 1 and is used to spray a nano-layer onto the surface of the photovoltaic panel. The leveling mechanism 4 is mounted on the robot body 1 and is used to level the sprayed nano-layer.

[0028] Reference Figure 1 The robot body 1 adopts a lightweight aluminum alloy frame structure. The robot body 1 spans above the two edges of the photovoltaic panel and is mounted above the photovoltaic panel via the moving mechanisms 2 on both sides, maintaining a gap of 10-15mm between itself and the surface of the photovoltaic panel to avoid direct contact with the coated area. The length of the robot body 1 is slightly larger than the width of the photovoltaic panel to ensure that the moving mechanisms 2 can be stably engaged on both sides of the photovoltaic panel.

[0029] Reference Figure 2The moving mechanism 2 includes a guide rail 21, a walking wheel 22, a driven wheel 23, and a drive motor 24. Two guide rails 21 are provided, parallel to each other and laid on opposite sides of the photovoltaic panel. The walking wheel 22 is fixedly installed on one end of the robot and is tactilely connected to one set of guide rails 21. The driven wheel 23 is fixedly installed on the other end of the robot and is tactilely connected to the other set of guide rails 21. The drive motor 24 is fixedly installed on the robot body 1, connected to the walking wheel 22, and drives the walking wheel 22 to rotate, thereby driving the robot body 1 to move on the guide rails 21. The driven wheel 23 ensures the robot body 1 moves forward stably. In this embodiment, two sets of driven wheels 23 are also provided at both ends of the robot body 1 near the leveling mechanism 4 to improve the stability of the robot body 1 during movement. An auxiliary roller is also provided at the bottom of the robot body 1, rolling in contact with the top of the guide rail 21. In this embodiment, the drive motor 24 is decelerated by a reducer before driving the walking wheel 22 to rotate.

[0030] Reference Figure 1 and Figure 2 Specifically, when the robot body 1 is placed on the photovoltaic panel mounting frame, the walking wheels 22 and driven wheels 23 respectively enter the two sets of guide rails 21. When spraying begins, the drive motor 24 starts, thereby driving the walking wheels 22 to rotate, causing the robot body 1 to move along the guide rails 21. At the same time, the robot body 1 drives the driven wheels 23 to roll. The driven wheels 23 and the walking wheels 22 form a two-point support mechanism to prevent the robot body 1 from tilting when moving. The robot's moving speed in this embodiment can be adjusted according to requirements.

[0031] Reference Figure 2 The spraying mechanism 3 includes a swing bar 31, nozzles 32, and a drive assembly 33. The swing bar 31 is horizontally mounted in the middle of the robot body 1 via a linear guide rail, and the sliding direction of the swing bar 31 is perpendicular to the moving direction of the robot body 1. Multiple sets of nozzles 32 are provided and are spaced apart on the swing bar 31. The nozzles 32 are used to spray nano-coating onto the photovoltaic panel. The drive assembly 33 is mounted on the robot body 1 and is used to drive the swing bar 31 to reciprocate and slide. In this embodiment, the distance between adjacent nozzles 32 is equal to the spraying range of the nozzle 32.

[0032] Reference Figure 2 and Figure 3The drive assembly 33 includes a rotary disk 331, a drive shaft 332, a sliding yoke 333, and a rotary motor 334. The rotary disk 331 is rotatably mounted on the robot body 1. The drive shaft 332 is fixedly mounted on the lower surface of the rotary disk 331, and the axis of the drive shaft 332 is eccentrically set with respect to the rotation axis of the rotary disk 331. The sliding yoke 333 is slidably mounted on the robot body 1, and the sliding direction of the sliding yoke 333 is parallel to the sliding direction of the swing bar 31. The sliding yoke 333 has a groove for connecting the sliding bar to the swing bar 31. The sliding grooves are perpendicular to each other. The end of the drive shaft 332 away from the rotating disk 331 is rolled in the sliding groove. The diameter of the drive shaft 332 is equal to the width of the sliding groove 411. The drive shaft 332 rolls and slides along the length of the sliding groove. The sliding yoke 333 is located in the middle of the swing bar 31. The sliding yoke 333 and the swing bar 31 are detachably and fixedly connected by the connecting frame 335. In this embodiment, the connecting frame 335, the sliding yoke 333, and the connecting frame 335 are all detachably connected by locking bolts.

[0033] Reference Figure 4 The leveling mechanism 4 includes a support block 41, a sliding block 42, a scraper 43, a damper 44, a first compression spring 45, and a second compression spring 46. The support block 41 is fixedly installed on the robot body 1, and a sliding groove 411 is formed on the side of the support block 41 near the photovoltaic panel. The sliding block 42 is slidably installed in the sliding groove 411. A limit ring 47 is fixedly installed on the support block 41 to prevent the sliding block 42 from sliding out of the sliding groove 411. The scraper 43 is fixedly installed on the sliding block 42 and is used to level the nano-layer after spraying. The fixed end of the damper 44 is fixedly installed on the bottom of the sliding groove 411, and the movable end of the damper 44 is fixedly connected to the sliding block 42. The damper 44 is used to dampen the sliding of the sliding block 42. The first compression spring 45 and the first compression spring 46 are also included. Spring 45 is sleeved on damper 44. The two ends of the first compression spring 45 are respectively pressed against the bottom of sliding groove 411 and sliding block 42. The first compression spring is used to push sliding block 42 to slide away from the bottom of sliding groove 411. The second compression spring 46 is disposed between limiting ring 47 and sliding block 42. The second compression spring 46 is used to push sliding block 42 to slide closer to the bottom of sliding groove 411. The first compression spring 45 and the second compression spring 46 together push sliding block 42 to slide in sliding groove 411, thereby pushing scraper 43 to press against photovoltaic panel. At the same time, in order to improve the stability of the second compression spring 46, positioning grooves are provided on sliding block 42 and limiting ring 47 to facilitate positioning of the second compression spring 46, thereby reducing the probability of bending deformation of the second compression spring 46.

[0034] The working principle of Embodiment 1 of this application is as follows: The drive motor 24 drives the walking wheel 22 to rotate, and multiple sets of driven wheels 23 cooperate with each other to make the robot body 1 move stably on the guide rail 21 of the photovoltaic panel. At the same time, the rotary motor 334 drives the rotating disk 331 to rotate, and the eccentrically set drive shaft 332 drives the sliding yoke 333 to reciprocate. Finally, the multiple sets of nozzles 32 on the swing bar 31 uniformly spray the nano coating with a curved trajectory. Then, under the synergistic action of the first compression spring 45 and the second compression spring 46, the scraper 43 scrapes the coating with constant pressure to reduce moisture, eliminate uneven thickness and spraying streaks, and finally improve the uniformity of the coating thickness.

[0035] Example 2 Reference Figure 5 , Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 is that the support block 41 is provided with an adjustment component 5 for adjusting the initial pressure values ​​of the first compression spring 45 and the second compression spring 46. The adjustment component 5 includes an adjustment plate 51 and a telescopic member 52. The adjustment plate 51 is slidably installed on the bottom side of the mounting groove. The adjustment plate 51 has a through hole for the damper 44 to pass through. The two ends of the first compression spring 45 are respectively pressed between the adjustment plate 51 and the sliding block 42. The telescopic member 52 is fixedly installed on the support block 41. The telescopic member 52 is used to push the adjustment plate 51 to slide closer to or further away from the sliding block 42. Specifically, when the telescopic member 52 pushes the adjustment plate 51 to slide, the first compression spring 45 and the second compression spring 46 extend and retract simultaneously, ultimately maintaining a balanced state.

[0036] Reference Figure 6 The support block 41 has an observation window for easy observation of the position of the adjustment plate 51. The observation window is made of transparent material and has scale lines for easy measurement of the distance between the adjustment plate 51 and the sliding block 42, and between the sliding block 42 and the limiting ring 47, so as to facilitate the adjustment of the position of the adjustment plate 51 and the measurement of the deformation of the first compression spring 45 and the second compression spring 46.

[0037] The working principle of Embodiment 2 of this application is as follows: Before the robot body 1 is started, the telescopic component 52 drives the adjustment plate 51 to slide, thereby adjusting the initial pressure values ​​of the first compression spring 45 and the second compression spring 46. Then, the positions of the sliding block 42 and the adjustment block are accurately read through the observation window and scale line, which makes it easier to measure the force exerted by the first compression spring 45 and the second compression spring 46 on the sliding block 42.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
