Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically a device for applying anti-fouling coating to photovoltaic modules. Background Technology

[0002] Existing conventional lightweight flexible photovoltaic modules have a high-transmittance film on their surface. After installation, dust accumulates on the surface of the photovoltaic modules over time, reducing the light transmittance of the front panel and significantly decreasing power generation efficiency. Regular cleaning is required to maintain the power generation efficiency of the modules. This situation seriously affects the power generation efficiency of photovoltaic modules and increases labor costs. The conventional operation is to manually apply a nano anti-fouling coating to the surface of the photovoltaic modules so that the surface can be self-cleaned by rainwater or dew. However, manual application has problems such as uneven application and high labor costs. Therefore, during the photovoltaic module manufacturing process, an anti-fouling coating is applied to the photovoltaic modules to achieve the effect of preventing contamination.

[0003] During the application of antifouling coatings to photovoltaic modules, a Teflon conveyor belt is used to transport the adhesive to the dispensing unit for dispensing, and then to the coating unit for coating. Currently, the coating unit typically uses multiple brush heads arranged in a row and rotating to apply the adhesive evenly to the surface of the photovoltaic module, which is then allowed to air dry naturally. However, the brush heads will wear down over time, and the residual adhesive on the brush heads will also affect their performance. Therefore, to ensure uniform adhesive application, the brush heads need to be replaced periodically. Currently, the brush heads are mostly fixed with a large number of bolts, making the disassembly and assembly of multiple brush heads on the coating unit very time-consuming and labor-intensive, increasing the burden of manual disassembly and assembly, and thus affecting the working efficiency of the photovoltaic module antifouling coating application device. Summary of the Invention

[0004] The purpose of this invention is to provide a photovoltaic module anti-fouling coating application device to solve the problem of cumbersome disassembly and assembly of the brush head used in the current photovoltaic module anti-fouling coating application devices.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution for a photovoltaic module anti-fouling coating application device, including a frame 1, a rotating rod 2 rotatably connected to the frame 1, and a track groove 4 opened on each of the two rotating rods 2 on opposite sides. The vertical cross section of the track groove 4 is a convex-shaped cavity. A linear array of track plates 5 are slidably connected inside the track groove 4. The vertical cross section of the track plate 5 is a convex-shaped structure. A brush head 6 is rotatably connected inside a rotating opening opened on one side of the track plate 5. The rotating rod 2 is provided with a rotating mechanism to drive the brush head 6 to rotate, and a fixing mechanism to fix the track plate 5.

[0024] The brush head 6 consists of a sponge head and a PTFE block;

[0025] When installing the brush head 6, rotate the rotating rod 2 to rotate the side of the track groove 4 where the brush head 6 needs to be replaced to the top of the rotating rod 2. Then, slide each track plate 5 into the cavity of the track groove 4 one by one from the groove opening on one side of the track groove 4, and make the adjacent track plates 5 contact each other. Then, use the fixing mechanism to fix the track plate 5 located at the end of the groove opening of the track groove 4.

[0026] The upper track groove 4 area of ​​the rotating rod 2 is a spare area, while the lower track groove 4 of the rotating rod 2 is the working area. Each time the rotating rod 2 is rotated 180°, the position of the brush head 6 on the two sets of track grooves 4 will be exchanged. In this way, the painting of photovoltaic modules will not be affected when the brush head 6 is disassembled or installed.

[0027] like Figure 1 As shown, a conveyor belt 18 is installed below the frame 1, and an adhesive dispensing device 19 is installed above the conveyor belt 18;

[0028] The conveyor belt 18 is a Teflon conveyor belt; the adhesive dispensing equipment 19 is an adhesive dispensing system, each dispensing nozzle is equipped with a solenoid valve, which automatically opens when the component arrives and starts to automatically dispense adhesive onto the component surface;

[0029] The photovoltaic module is slowly moved by the conveyor belt 18. The photovoltaic module will first pass through the glue dispensing device 19, where glue is dispensed. Then the photovoltaic module is transported to the fixed frame 3, where the brush head 6 on the fixed frame 3 is used to apply the glue to the surface of the photovoltaic module.

[0030] like Figure 1 As shown, two sets of fixed frames 3 are provided on the frame 1. The frame 1 is slidably connected to both sets of fixed frames 3. A hydraulic cylinder 15 is fixedly connected to the top of the fixed frame 3. The telescopic end of the hydraulic cylinder 15 is fixedly connected to the upper part of the frame 1. The brush heads 6 on the two sets of frame 1 are staggered with each other.

[0031] The brush heads 6 on the two sets of fixing brackets 3 are staggered to avoid leaving gaps between two adjacent brush heads 6. Each brush head 6 in the second set is located in the gap area between each brush head 6 in the first set. This increases the uniformity of coating on the photovoltaic module surface and avoids uncoated areas on the photovoltaic module surface due to gaps between two adjacent brush heads 6.

[0032] like Figure 2 - Figure 5 As shown, the inner wall of the track groove 4 is formed with a groove. The rotating mechanism includes a linear array of first gears 7, each of which is connected to the first gear in sequence. Each first gear 7 is rotatably connected to the inner wall of the groove. A connecting block 8 is fixedly connected to one side of the first gear 7. A connecting groove 9 is opened on one side of the brush head 6. The connecting block 8 is adapted to the cavity of the connecting groove 9.

[0033] When installing the brush head 6, the first gear 7 needs to be rotated in advance so that the connecting blocks 8 are aligned in a straight line and the connecting blocks 8 are directly opposite the cavity of the connecting groove 9 where the brush head 6 slides. In this way, when installing the brush head 6, each brush head 6 is located directly above each of the first gears 7, and the connecting blocks 8 on the first gear 7 slide into the cavity of the connecting groove 9. By utilizing the docking of the connecting groove 9 and the connecting blocks 8, when the first gear 7 is rotated, the first gear 7 can drive the brush head 6 to rotate on the track plate 5.

[0034] like Figure 2 - Figure 5 As shown, a worm gear 10 is fixedly connected to one side of the first gear 7 at the end, a worm 11 is meshed with one side of the worm gear 10, the worm 11 is rotatably connected to the inner wall of the groove, a second gear 12 is fixedly connected to the end of the worm 11, and a third gear 13 that meshes with the second gear 12 is rotatably connected to the inner wall of one side of the frame 1.

[0035] By rotating the third gear 13, the third gear 13 drives the worm 11 to rotate via the second gear 12. The worm 11 drives the corresponding first gear 7 to rotate via the worm wheel 10. The first gear 7 drives the other first gears 7 to rotate together.

[0036] The third gear 13 is located outside the movement trajectory of the second gear 12 rotating around the axis of the rotating rod 2. When the second gear 12 moves to the position of the third gear 13, the axes of the second gear 12, the third gear 13, and the rotating rod 2 are on the same straight line. The second gear 12 is located between the rotating rod 2 and the third gear 13. At this time, the second gear 12 is just meshed with the third gear 13.

[0037] When the second gear 12 and the third gear 13 are engaged, the servo motor 14 can be used to drive the third gear 13 to rotate slowly, which facilitates the engagement of the second gear 12 and the third gear 13. Alternatively, the second gear 12 or the third gear 13 can be manually rotated to facilitate successful engagement of the second gear 12 and the third gear 13.

[0038] like Figure 2 , Figure 3 and Figure 5 As shown, a shaft is fixedly connected to the end of the rotating rod 2, and two servo motors 14 are installed on the frame 1. The movable ends of the two servo motors 14 are fixedly connected to the shaft center of the third gear 13 and the end of the shaft, respectively.

[0039] The servo motor 14 is a PTFE motor, and two servo motors 14 are used to drive the rotating rod 2 and the third gear 13 to rotate respectively.

[0040] like Figure 2 - Figure 4 As shown, a pin groove is provided at the end of the rotating rod 2 away from the shaft, and a pin 16 is slidably connected in the pin groove. The end of the pin 16 away from the rotating rod 2 is a semi-circular head. A spring is provided between the other end of the pin 16 and the inner wall of the pin groove. Two semi-circular slots 17 are provided on the inner wall of the frame 1 at the corresponding positions relative to the pin groove.

[0041] When the rotating rod 2 rotates 180°, one of the slots 17 on the rotating rod 2 is exactly aligned with the pin slot. At this time, the pin slot is partially ejected by the elastic force of the pin 16, and the semi-circular head at the end of the pin 16 is inserted into the cavity of the slot 17, thereby improving the stability of the rotating rod 2 after rotation.

[0042] like Figure 2 - Figure 4 As shown, the fixing mechanism includes a threaded rod 20, and a through threaded hole is provided on the upper part of the track plate 5 at the end. The threaded rod 20 is threadedly connected to the cavity of the threaded hole, and a slot 21 is provided at the corresponding position of the track groove 4 relative to the threaded hole.

[0043] By rotating the threaded rod 20, the movable end of the threaded rod 20 is inserted into the slot 21, thereby stably fixing the track plate 5 in the cavity of the track groove 4.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
