Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel packaging technology, and more specifically, to a device for an external coating material for photovoltaic panels. Background Technology

[0002] Photovoltaic panel external coating material device is an automated equipment used to cover the surface of photovoltaic panels with protective or functional films. By attaching a polymer film to the surface of the photovoltaic panel, it prevents the photovoltaic panel from being scratched during transportation and installation, resists environmental erosion such as ultraviolet rays, wind and sand, and acid rain, and improves its anti-PID degradation performance. At the same time, some functional coatings can also enhance light transmittance or achieve self-cleaning effects. This device can significantly improve the yield rate, service life and power generation efficiency of photovoltaic modules, and is one of the key equipment in the photovoltaic intelligent manufacturing industry chain.

[0003] In traditional photovoltaic panel coating processes, the film material is prone to static electricity due to friction during storage, transportation, and unwinding, which actively attracts fine dust and flocculent matter from the environment. At the same time, its surface is often in a low surface energy state and has strong chemical inertness. If coating is carried out directly in this state, these attached contaminants will form an isolation layer at the interface between the film and the photovoltaic panel. The film material itself is also difficult to generate sufficient intermolecular forces with the panel surface. As a result, a large number of tiny air bubbles are actually hidden under the seemingly smooth surface after coating. Moreover, the edge area is the first to warp due to stress concentration. As time goes by and the ambient temperature and humidity change, these initial defects will further develop into large-area bubbles that are visible to the naked eye, star-shaped scale-like delamination, or whole-sheet peeling. This not only completely loses the scratch-resistant and weather-resistant protection functions that the coating should have, but also significantly reduces the factory yield and market competitiveness of photovoltaic modules by affecting light transmission and aesthetics.

[0004] In summary, to improve the adhesion of membrane materials, it is necessary to address the problem that traditional coating material devices lack effective cleaning and activation treatment of the membrane surface, resulting in insufficient adhesion between the membrane and the photovoltaic panel, which seriously affects the protective effect of the coating and the long-term reliability of the product. The coating material device should be able to perform timely dust removal treatment on the membrane surface. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic panel external coating material device, comprising a coating shell and a feeding roller rotatably connected to the coating shell, a placement platform fixedly connected to the coating shell, two symmetrical sliding grooves formed on the placement platform, a positioning component installed inside the placement platform, two baffles connected to the output end of the positioning component, the baffles and the sliding grooves being slidably connected, the positioning component being used to drive the two baffles to move in opposite directions along the sliding grooves, an auxiliary roller fixedly connected to the coating shell, a plurality of plasma nozzles fixedly connected to the auxiliary roller, two symmetrical tensioning components installed on the coating shell, a tensioning roller connected between the output ends of the two tensioning components, the tensioning components being used to drive the tensioning roller to move in the vertical direction.

[0009] In a preferred embodiment, a dust collection tank and a vacuum cleaner are fixedly connected to the coated housing, and a plurality of negative pressure suction tubes are fixedly connected between the vacuum cleaner and the dust collection tank.

[0010] In a preferred embodiment, two symmetrical linear modules are provided on both sides of the placement platform. The linear modules are fixedly connected to the film-coated housing.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figures 1 to 6 A photovoltaic panel external coating material device includes a coating housing 1 and a feeding roller 2 rotatably connected to the coating housing 1. A placement platform 3 is fixedly connected to the coating housing 1. Two symmetrical sliding grooves 301 are opened on the placement platform 3. A positioning component is installed inside the placement platform 3. Two baffles 5 are connected to the output end of the positioning component. The baffles 5 and the sliding grooves 301 are slidably connected. The positioning component is used to drive the two baffles 5 to move in the opposite direction along the sliding grooves 301. An auxiliary roller 6 is fixedly connected to the coating housing 1. Several plasma nozzles 7 are fixedly connected to the auxiliary roller 6. Two symmetrical tensioning components are installed on the coating housing 1. A tensioning roller 9 is connected between the output ends of the two tensioning components. The tensioning components are used to drive the tensioning roller 9 to move in the vertical direction.

[0024] It should be noted that the placement platform 3 is the working surface that supports the photovoltaic panel to be coated. When the photovoltaic panel is placed on the placement platform 3, the positioning component synchronously drives the two baffles 5 to move in opposite directions along the slide groove 301, thereby adapting to photovoltaic panels of different widths and clamping and positioning them from both sides to ensure that the photovoltaic panel will not shift during the coating process and to ensure coating accuracy.

[0025] It is worth noting that the auxiliary roller 6, as a guide roller for the membrane, can not only change the membrane's transport path but also serve as a mounting base for the plasma nozzle 7. It is equipped with an external blower. When the tensioning assembly controls the movement of the tensioning roller 9 to adjust the tension of the membrane in the transport path, the membrane is stretched and tends to accumulate more dust on its surface. At this time, the plasma nozzle 7 sprays low-temperature plasma onto the membrane surface to clean it, eliminating the dust adsorbed by electrostatic charge, making subsequent lamination more secure and bubble-free, and effectively improving product quality.

[0026] Refer to the instruction manual appendix Figure 3 The positioning assembly includes an electric push rod 401 fixedly connected to the placement platform 3, an active slide 402 fixedly connected to the output end of the electric push rod 401, two racks 403 symmetrically fixedly connected to the active slide 402, two gears 404 respectively meshing with one side of the two racks 403, two racks 405 respectively meshing with the other side of the gears 404, and a passive slide 406 fixedly connected to the two racks 405. The gears 404 are rotatably connected to the placement platform 3, and the racks 403 and 405 are slidably connected to the placement platform 3. The electric push rod 401 and the passive slide 406 are both fixedly connected to the baffle 5. The electric push rod 401 is used to drive the active slide 402 to move in a preset direction.

[0027] It should be noted that gear 404 is the core component for achieving synchronous reverse motion. Each gear 404 acts like a "commutator" and meshes with a rack 1 403 and a rack 2 405. Gear 404 is rotatably connected to the placement platform 3, ensuring its rotational stability. Furthermore, the dimensions of rack 1 403, rack 2 405, and gear 404 are compatible.

[0028] Refer to the instruction manual appendix Figure 6 The tensioning assembly includes a slide rail 801 fixedly connected to the film-coated housing 1, a motor 802 fixedly connected to the slide rail 801, a threaded rod 803 fixedly connected to the output end of the motor 802, and a slider 804 threadedly connected to the threaded rod 803. The threaded rod 803 and the slide rail 801 are rotatably connected, the slider 804 and the slide rail 801 are slidably connected, and the slider 804 and the tensioning roller 9 are fixedly connected. The motor 802 is used to drive the threaded rod 803 to rotate.

[0029] It should be noted that the slider 804 has a threaded hole, the size of which is adapted to the threaded rod 803, so that the rotational motion of the threaded rod 803 is converted into the linear motion of the slider 804. At the same time, the movement of the slider 804 is restricted by the slide rail 801, so as to achieve precise control of the tension roller 9.

[0030] Refer to the instruction manual appendix Figure 2A dust collection tank 10 and a vacuum cleaner 12 are fixedly connected to the film-coated housing 1, and several negative pressure suction tubes 11 are fixedly connected between the vacuum cleaner 12 and the dust collection tank 10.

[0031] It should be noted that the dust collection trough 10 is a long strip with an open top, which is fixedly installed on the film housing 1. Multiple negative pressure suction pipes 11 are evenly arranged on the dust collection trough 10 to ensure that the suction force is uniform throughout the entire length of the dust collection trough 10.

[0032] It is worth noting that the dust collection trough 10 is arranged between the tension roller 9 and the auxiliary roller 6, and is mainly used to adsorb and collect the dust, organic pollutants and fine particles blown off and peeled off by the plasma nozzle 7 when treating the surface of the membrane material.

[0033] Refer to the instruction manual appendix Figure 4 Two symmetrical linear modules 13 are provided on both sides of the placement platform 3. The linear modules 13 are fixedly connected to the film-coated housing 1. The output end of the linear modules 13 is fixedly connected to the electric push rod 14. The linear modules 13 are used to drive the electric push rod 14 to move along a preset direction. A mounting plate 15 is fixedly connected between the output ends of the two electric push rods 14. The electric push rod 14 is used to drive the mounting plate 15 to move along a preset direction. Several negative pressure suction cups 16 are fixedly connected to the bottom of the mounting plate 15.

[0034] It should be noted that the negative pressure suction cup 16 is a component that directly contacts the membrane material. By drawing a vacuum to generate negative pressure, it can reliably adsorb the surface of the membrane material. The design of "several" evenly distributed suction cups is to ensure that a whole wide film can be firmly gripped, preventing the membrane material from falling off or sagging and wrinkling in the middle during rapid movement.

[0035] Refer to the instruction manual appendix Figure 4 Two symmetrical linear modules 17 are fixedly connected to both sides of the film-coated housing 1. A connecting slide 18 is fixedly connected between the output ends of the two linear modules 17. The linear modules 17 are used to drive the connecting slide 18 to move in a preset direction. An electric push rod 19 is fixedly connected to the connecting slide 18. A scraper 20 is fixedly connected to the output end of the electric push rod 19. The electric push rod 19 is used to drive the scraper 20 to move in the vertical direction.

[0036] It should be noted that the scraper 20 is a component that directly contacts the surface of the membrane material. It is made of a material with certain elasticity and wear resistance (such as silicone, polyurethane or special engineering plastics). Its bottom edge is designed with rounded corners. After the membrane material is laid on the surface of the photovoltaic panel, it ensures that the membrane material and the photovoltaic panel are completely adhered and removes internal air, so as to achieve a bubble-free and highly adhesive coating effect.

[0037] Refer to the instruction manual appendix Figure 4The scraper 20 is equipped with a pressure sensing module, which is used to detect the pressure applied to the photovoltaic panel by the scraper 20 and transmit an electrical signal to the electric push rod 319 to control the movement of the scraper 20.

[0038] It should be noted that the pressure sensing module is a high-precision force sensor embedded in the structure of the scraper 20. It directly measures the interaction force generated when the scraper 20 comes into contact with the film material and photovoltaic panel, and converts this physical quantity into a standard electrical signal, thereby controlling the movement of the electric push rod 319 to ensure uniform pressure throughout the process.

[0039] Working principle: The photovoltaic panel to be coated is placed on the placement platform 3. The electric push rod 401 drives the active slide 402 to move, which in turn drives the two racks 403 to move. The racks 403 drive the gears 404 to rotate, and the gears 404 drive the racks 405 on the other side to move in the opposite direction. The passive slide 406, which is fixed to the racks 405, moves in conjunction with the active slide 406, which in turn moves the two baffles 5 towards each other along the slide groove 301, clamping the photovoltaic panel from both sides to complete the positioning. At the same time, the film roll is drawn out from the feed roller 2. After passing through the auxiliary roller 6, the film material passes through the tension roller 9. Meanwhile, the motor 802 drives the threaded rod 803 to rotate, which causes the threaded slider 804 to move up and down along the slide rail 801, thereby precisely adjusting the height of the tension roller 9 to control the tension of the film material. After tensioning, the film material is cleaned and activated by the low-temperature plasma sprayed by the plasma nozzle 7 on the auxiliary roller 6. The dust on the film is blown off, and the blown-off contaminants are located on the tension roller 9. Dust is collected in the dust collection groove 10 between the tightening roller 9 and the auxiliary roller 6. The dust collection groove 10 is connected to the vacuum cleaner 12 through the negative pressure suction pipe 11 to form a negative pressure adsorption system to remove dust in time. Then, the linear module 13 drives the electric push rod 2 14 to move laterally above the clean film material. The electric push rod 2 14 descends so that several negative pressure suction cups 16 at the bottom of the mounting plate 15 contact and adsorb the film material. After lifting and transferring it above the starting end of the positioned photovoltaic panel, the negative pressure suction cups 16 break the vacuum and lay the film material on the panel surface. Finally, the linear module 2 17 drives the connecting slide 18 to move along the length of the photovoltaic panel. The electric push rod 3 19 on the connecting slide 18 drives the scraper 20 to descend and press. The pressure sensing module integrated inside the scraper 20 detects the pressure in real time and feeds back the signal to control the extension and retraction of the electric push rod 3 19, thereby ensuring that the scraper 20 completely removes the air between the film material and the photovoltaic panel under constant and uniform pressure, completing a high-quality film coating with no bubbles and high adhesion.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
