Description

Technical Field

[0001] The present disclosure relates to a coating assembly and a dispensing device, and more particularly to a coating assembly and a dispensing device for solar panel coatings. Background Art

[0002] Solar panels typically have a protective top layer made of glass or plastic to protect the solar cells underneath. However, while this protective top layer can be made of a highly transmittance material, it still has a certain light reflectivity, which reduces the amount of light received by the solar cells. To improve the efficiency of solar cells, performance-enhancing coatings (such as coatings on the top surface of the protective top layer made of glass or plastic that reduce the light reflectivity of the protective top layer) are necessary. When the light reflectivity of the solar panel surface is reduced, the solar panel's light absorption and conversion efficiency can be effectively improved.

[0003] Solar panels (and their protective top layers) typically have large areas and require a uniform coating of uniform thickness to be effective. Furthermore, as solar panels are exposed to the outdoors for extended periods, the performance of the coating degrades over time, requiring regular outdoor coating applications.

[0004] In addition to solar panels, many windows also require functional thin film coatings. For example, for glass windows installed in commercial buildings and storefronts, many glass windows may have anti-glare coatings, but these windows have already been installed and when new window glass coatings need to be applied, appropriate coating equipment is also required.

[0098] The following disclosure provides many different embodiments or examples for implementing the different features of the provided subject matter. Specific examples of components and configurations will be described below to simplify the present disclosure. Of course, these are merely examples and are not intended to be limiting. For example, in the following description, "forming a first component above or on a second component" may include embodiments in which the first component and the second component are directly contacted, and may also include embodiments in which additional components may be formed between the first component and the second component so that the first component and the second component may not be in direct contact. In addition, the present disclosure may repeat element symbols and / or letters in various examples. This repetition is intended to simplify and clarify and does not itself indicate a relationship between the various embodiments and / or configurations discussed.

[0099] Furthermore, for convenience of description, spatially relative terms (such as "below," "beneath," "below," "above," "upper," and the like) may be used herein to describe the relationship of one element or component to another element or component, as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0100] As used herein, terms such as "first," "second," and "third" describe various elements, components, regions, layers, and / or sections, and these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, the terms such as "first," "second," and "third" used herein do not imply a sequence or order.

[0101] As used herein, the terms "substantially," "substantially," and "about" are used to describe and explain small variations. When used in conjunction with an event or condition, the terms may relate to instances in which the event or condition occurred precisely as well as instances in which the event or condition occurred very approximately. For example, when used in conjunction with a numerical value, the terms may relate to a range of variation less than or equal to ±10% of the numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if the difference between two numerical values ​​is less than or equal to ±10% of an average of the values ​​(such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%), then the values ​​may be considered to be "substantially" the same or equal. For example, "substantially" parallel can involve an angular variation of less than or equal to ±10° relative to 0°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, "substantially" perpendicular can involve an angular variation of less than or equal to ±10° relative to 90°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

[0102] Anti-reflective coatings for solar panels are special coatings used to reduce reflections from the panel surface and improve light absorption efficiency. These coatings are typically made from a special coating with anti-reflective properties. Anti-reflective coatings are typically composed of a variety of materials, the most common of which are silica (SiO2) and aluminum oxide (Al2O3) nanoparticles. These materials have high refractive index and low reflectivity and can self-assemble to form appropriate anti-reflective structures (such as moth-eye structures) that effectively reduce light reflection. In addition, the coating may also contain other additives, such as organic solvents and polymers, to increase the coating's adhesion and durability. The preparation process for anti-reflective coatings typically involves the following steps: First, solid raw materials are dissolved or dispersed in an organic solvent to form a uniform solution. The solution is then applied to the surface of the solar panel. After coating, the coating can be heat-treated as needed to solidify and increase adhesion.

[0103] This disclosure discloses an atomizer designed based on the density and viscosity characteristics of coatings (particularly resin coatings used for solar panel coatings) that can be integrated with a portable coating applicator. Based on the width characteristics of the coating applicator, the atomizer is designed with a predetermined diffusion angle, linear atomization, and flow control to uniformly replenish the coating applicator and ensure uniform adsorption of the coating. This coating applicator can perform a continuous coating process, transferring a continuous and uniform wet film over a large area onto the solar panel, which is then dried to form an anti-reflective film.

[0104] Furthermore, each time the coating device is placed on the surface to be coated, the deformation of the sponge and felt layers of the coating device is predictable and repeatable. This geometry ensures that the coating element can evenly contact the surface, thereby achieving uniform coating. At the same time, the coating element can quantitatively and evenly supply the coating through the atomization device, so that the amount of coating absorbed by the coating device can be kept basically constant, thus ensuring coating consistency.

[0105] Figure 1 A coating assembly 100 according to one embodiment of the present disclosure is shown. The coating assembly 100 includes an operating element 10, a coating device 200, and a spraying device 300. The operating element 10 can be a rod, a cart, or the like. Furthermore, the operating element 10 can be further connected to a robot or an automated coating assembly having a drive mechanism. The coating device 200 directly contacts the component to be coated, such as a solar panel, and can be moved over the component to be coated via the operating element 10.

[0106] The spraying device 300 is configured to move with the coating device 200. In some embodiments of the present disclosure, the spraying device 300 and the coating device 200 are connected to each other. The spraying device 300 has a plurality of dispensing devices 304, and the dispensing devices 304 can be connected to a paint supply pipeline 302 for providing a paint for an anti-reflective coating. The plurality of dispensing devices 304 of the spraying device 300 can dispense and spray the paint on the component to be coated, and the coating device 200 can apply the paint dispensed on the component to be coated to the component to be coated.

[0107] Figure 2A top view schematically illustrates a coating process using a coating device according to an embodiment of the present disclosure. The coating device 200 can contact and / or cover the element 20 to be coated, and can be moved in a coating direction 50 by a user. In some embodiments, the spraying device 300 is disposed in front of the coating device 200 along the coating direction 50. Thus, during operation, the dispensing device 304 of the spraying device 300 can spray the coating 30 onto the surface 40 to be coated of the element 20 to be coated. At the same time, the coating device 200 moves along the coating direction 50, and the coating device 200 evenly coats the coating 30 sprayed onto the surface 40 to be coated of the element 20 to be coated. In some embodiments, the element 20 to be coated can be a solar heat sink, window glass, eyeglass lens, or any other transparent or opaque object having at least one reflective surface.

[0108] Specifically, the coating device 200 can be brought into contact with the component 20 to be coated by operating the device 10 and moved along a movement path on the component 200 to be coated, while the spray device 300 is configured to move along with the coating device 200. The dispensing device 304 of the spray device 300 can dispense the coating 30 onto the component 20 to be coated, and the coating 30 is dispensed along the movement path. Thus, when the coating device 200 moves along the movement path, the coating 30 can be applied to the surface 40 to be coated of the component 20 to be coated.

[0109] When the coating 30 is first applied to the surface 40 to be coated, it is in a colloidal solution containing a solvent. The coated surface is then covered with a wet film. The solvent in the wet film can evaporate during coating due to ambient heat or by applying an appropriate heat treatment.

[0110] Figure 3A and Figure 3B The coating device 200 according to one embodiment of the present disclosure is shown. The coating device 200 may be substantially in the shape of a long plate, and may be Figure 3B As shown, the coating device 200 can form a surface contact with the surface to be coated 40 to coat the coating on the surface to be coated 40 .

[0111] The coating device 200 may comprise three distinct layers: a felt layer 202, a sponge layer 204, and a shaping layer 206. The sponge layer 204 can absorb and temporarily store the coating. The felt layer 202 (which can be made of microporous fabric or high-porosity foam) has a capillary structure that can transfer the coating through capillary action. For example, it can transfer excess coating sprayed onto the surface to be coated to the sponge layer 204, or transfer coating to the surface to be coated when there is insufficient coating on a certain area of ​​the surface to be coated, thereby achieving a uniform coating across the entire surface. When the coating device 200 contacts the surface to be coated 40, the geometric deformation of the felt layer 202 and the sponge layer 204 of the coating device 200 is predictable and repeatable. More specifically, the felt layer 202 can be made of a variety of fibers and any thickness, and has a very fine and soft texture, which is ideal for evenly spreading liquid on the surface. The micropores of the felt interface or the interface formed by other materials effectively act as an array of capillaries that absorb, store, and / or transfer the coating to the surface to be coated in a substantially uniform manner on the contact surface of the coating device 200. The shaping layer 206 can be made of hard foam and attached to the side of the sponge layer 204 opposite the felt layer 202 to shape the overall geometry of the coating device 200.

[0112] According to an embodiment of the present disclosure, the coating device 200 has a length of 100 cm and a width of 3.5-6 cm, while the thickness of the felt layer 202 is about 1 mm and the thickness of the sponge layer 204 is about 10 mm.

[0113] According to an embodiment of the present disclosure, the coating supplied by the spraying device 300 may not be sprayed directly onto the surface to be coated 40 , but may be supplied to the coating device 200 , particularly to the sponge layer 204 of the coating device 200 .

[0114] Figure 4 A coating device 200' according to an embodiment of the present disclosure is shown, which differs from the coating device 200 in that the lateral cross-section of the felt layer 202' (and the sponge layer) of the coating device 200' is arc-shaped, so that the coating device 200' can form a line contact with the surface to be coated 40, and the direction of the line contact is perpendicular to the coating direction 50.

[0115] Figure 5 A spraying device 300 according to an embodiment of the present disclosure is shown. The spraying device 300 includes a plurality of dispensing devices 304, which can be fixed to a bracket 306 at equal intervals. One end of each dispensing device 304 is fluidly connected to a paint supply line 302, and the other end of each dispensing device 304 sprays atomized paint 30 at a predetermined diffusion angle 60 onto a surface 40 to be coated.

[0116] According to one embodiment of the present disclosure, the spraying device 300 has four dispensing devices 304, which are spaced 15-20 cm apart. The predetermined diffusion angle 60 is approximately 60 degrees. In the above embodiment, the spraying device 300 can apply a uniform linear coating over a width of 50-60 cm and apply 70-80 mL of coating per minute (78-80 mL / min). Thus, the coating area has at least a width of approximately 50-60 cm.

[0117] By the public Figures 6 to 11 As can be seen from the embodiment of the present disclosure, the dispensing device 304 of the present disclosure may be composed of two parts, namely a throttling element 310 and an atomizing element 308. One end 3101 of the throttling element 310 is fluidically connected to the paint supply pipeline 302, and the other end 3102 has a plurality of micropores 318. In some embodiments, the plurality of micropores 318 may form a micropore array. The micropores 318 of the micropore array can supply the paint from the paint supply pipeline 302 to the atomizing element 308 at a fixed rate. According to one embodiment of the present disclosure, each of the micropores 318 has a diameter of 0.03 mm, and the number and diameter of the micropores 318 can be changed depending on the required paint flow rate. The throttling element 310 has a stopper 316. When the atomizing element 308 is assembled to the throttling element 310, the stopper 316 can define the depth of the assembly of the atomizing element 308 and the throttling element 310 to avoid damaging the end features of the components, such as the micropores 318.

[0118] The atomizing element 308 and the throttling element 310 can be coupled together by interference fit, or assembled together by an appropriate coupling structure. For example, the throttling element 310 can have an external thread, and the atomizing element 308 can have a corresponding internal thread, and they are locked to each other by these threads. In some embodiments, the atomizing element 308 has a sleeve 3080 that is configured to surround and / or accommodate the end 3102 of the throttling element 310. Figure 8 It can be clearly seen that after the atomizing element 308 is coupled to the throttling element 310, the atomizing element 308 and the throttling element 310 can define a chamber 326 in the sleeve 3080. In this way, the paint supplied from the paint supply line 302 to the throttling element 310 can be converged into the chamber 326 through the micropores 318, and then leave the dispensing device 304 at a predetermined diffusion angle through the opening 330 of the atomizing element 308.

[0119] The volume of chamber 326 is determined by the depth to which throttling element 310 penetrates atomizing element 308. In other words, the cooperation and relative movement of throttling element 310 and atomizing element 308 adjust the volume of chamber 326. During operation, the user can determine the volume of chamber 326 by observing the width of gap 328 between the end of atomizing element 308 and stopper 316.

[0120] Ginseng Figure 8 , the atomizing element 308 has an opening 330 . In some embodiments, the opening 330 has a first portion 332 , a second portion 334 , and a slot 335 .

[0121] The first portion 332 of the opening 330 is connected to the chamber 326, and has one end connected to the chamber 326 and the other end connected to the second portion 334. In some embodiments, the first portion 332 of the opening 330 is funnel-shaped to facilitate the collection of paint in the chamber 326. Thus, when observed in cross section, the first portion 332 of the opening 330 tapers from the end connected to the chamber 326 toward the end connected to the second portion 334.

[0122] The second portion 334 of the opening 330 is connected to and in fluid communication with the first portion 332. The second portion 334 has an elongated capillary structure. When the paint flows through the second portion 334, a laminar flow is formed, thereby achieving a stable atomization effect when the paint is sprayed by the dispensing device 304. In some embodiments, the capillary structure has a diameter of approximately 0.3 mm.

[0123] The opening 330 has a slot 335 , one end of which is connected to the second portion 334 and in fluid communication with the other end of the slot 335 . The slot 335 also has two opposing inner walls 3351 and 3352 .

[0124] Figure 9A is an embodiment of the disclosed slot 335, such as Figure 9A As shown, the slot 335A has two inner walls 3351A and 3352A opposite to each other; the two inner walls 3351A and 3352A extend substantially parallel to each other, such that the angle between the two inner walls 3351A and 3352A is approximately 0 degree.

[0125] Figure 9B is an embodiment of the disclosed slot 335, such as Figure 9B As shown, the slot 335B has two opposing inner walls 3351B and 3352B. The inner walls 3351B and 3352B extend downwardly away from each other, i.e., the distance between the inner walls 3351B and 3352B gradually increases from the second portion 334 toward the exterior of the atomizing element 308. In some embodiments, the inner walls 3351B and 3352B form a roughly V-shape, with the V-shape forming an angle of approximately 8 degrees. In some embodiments, the minimum distance between the inner walls 3351B and 3352B is 0.07 mm. In some embodiments, the maximum distance between the inner walls 3351B and 3352B is 0.35 mm.

[0126] Figure 9C is an embodiment of the disclosed slot 335, such as Figure 9C As shown, the slot 335C has two opposing inner walls 3351C and 3352C. The inner walls 3351C and 3352C extend downwardly away from each other, i.e., the distance between the inner walls 3351C and 3352C gradually increases from the second portion 334 toward the exterior of the atomizing element 308. In some embodiments, the inner walls 3351C and 3352C form a generally V-shape, with the V-shape forming an angle of approximately 12 degrees.

[0127] Figure 9D is an embodiment of the disclosed slot 335, such as Figure 9D As shown, the slot 335D has two opposing inner walls 3351D and 3352D. The inner walls 3351D and 3352D extend downwardly away from each other, i.e., the distance between the inner walls 3351D and 3352D gradually increases from the second portion 334 toward the exterior of the atomizing element 308. In some embodiments, the inner walls 3351D and 3352D form a generally V-shape, with the V-shape forming an angle of approximately 16 degrees.

[0128] Figure 9E An embodiment of the slot 335 is disclosed, such as Figure 9E As shown, the slot 335E has two opposing inner walls 3351E and 3352E. The inner walls 3351E and 3352E extend downwardly away from each other, i.e., the distance between the inner walls 3351E and 3352E gradually increases from the second portion 334 toward the exterior of the atomizing element 308. In some embodiments, the inner walls 3351E and 3352E form a generally V-shape, with the V-shape forming an angle of approximately 20 degrees.

[0129] In addition, the end 3102 of the throttling element 310 has a leak-proof structure 320, which can be a semi-spherical protrusion. It can close or open the opening 330 by adjusting the coupling state of the atomizing element 308 and the throttling element 310. For example, when the atomizing element 308 is pushed against the stopper 316, the leak-proof structure 320 can be pressed against the first part 332 of the opening 330, stopping the paint from flowing from the opening 330 to the outside of the dispensing device 304.

[0130] A cylindrical protrusion 312 is formed on one side of the atomizing element 308 opposite to the chamber 326 and is disposed corresponding to the opening 330. According to one embodiment of the present disclosure, a slot 335 is formed in the cylindrical protrusion 312.

[0131] In some embodiments, the diameter of the second portion 334 is approximately 0.3 mm. Figure 10As shown, the distance between the two inner walls 3351 and 3352 of the slot 335 facing each other is smaller than the diameter of the second portion 334 .

[0132] When the paint flows from chamber 326 through first and second portions 332, 334 of opening 330 to slot 335, it is guided by inner walls 3351 and 3352 of slot 335 and atomized, exiting dispensing device 304 at a predetermined diffusion angle. As the paint flows into slot 335 and is atomized and sprayed out, it may accumulate at the edge where slot 335 meets cylindrical protrusion 312, causing droplets to drip (sag), resulting in excess paint on parts of the coated surface and uneven coating. This occurs because when the high-pressure liquid column is ejected from the oblique edge of the V-groove and instantly returns to an open state, the kinetic energy of the fluid is instantly reduced. Any contact surface may cause the atomized fluid to adhere, accumulating large droplets and causing sag. To avoid this problem, the diameter of the cylindrical protrusion 312 (or the overall length of the slot 335) should not be too large, allowing all paint flowing into the slot 335 to be uniformly atomized under the action of fluid pressure and simultaneously exit the dispensing device 304. According to one embodiment of the present disclosure, the short groove-shaped slot 335 formed with a cylindrical protrusion 312 having a diameter of 3-5 mm can significantly improve the phenomenon of fluid accumulation at the edge and prevent droplet accumulation.

[0133] The included angle of the V-shaped slot 335 affects the predetermined diffusion angle of the paint when it leaves the dispensing device 304. According to one embodiment of the present disclosure, the included angle of the V-shaped slot 335 is less than 20 degrees; according to one embodiment of the present disclosure, the included angle of the V-shaped slot 335 is 0 degrees (i.e., the two sidewalls of the slot 335 are parallel), 4 degrees, 8 degrees, 12 degrees, 16 degrees, or 20 degrees; according to one embodiment of the present disclosure, the included angle of the V-shaped slot 335 is 16 degrees; according to one embodiment of the present disclosure, the predetermined diffusion angle of the paint when it leaves the dispensing device 304 is 60 degrees. When the predetermined diffusion angle is 60 degrees, the spacing between each dispensing device 304 can be roughly consistent with the height of the dispensing device 304, that is, the surface to be coated (when the predetermined diffusion angle is 60 degrees, any two dispensing devices 304 and the intersection of the perpendicular lines therein and the surface to be coated can form the three vertices of an equilateral triangle). Therefore, it is convenient to form a linear coating supply according to the width to be coated, such as the width of the coating element, by arranging several dispensing devices 304 at equal intervals.
