Description

Technical Field

[0001] This invention relates to the field of photovoltaic manufacturing technology, and in particular to a method for installing a photovoltaic frame. Background Technology

[0002] For outdoor solar power generation, the main return on investment comes from the daily electricity output of the photovoltaic panels. However, outdoor environments often face various challenges, including dusty surroundings where dust settles on the panel surface. During rainy weather, if rainwater mixed with dust doesn't drain away promptly, the dust accumulates around the edges after drying, obstructing the photovoltaic cells and affecting the module's power generation. Furthermore, the frame and glass of the photovoltaic panels need to maintain strength, requiring a certain thickness, which also affects dust removal.

[0003] To remove accumulated dust, existing technologies use a flow guide and mud guide added to the edge of the frame. However, this is affected by the material and installation location, and the maintenance and replacement of the flow guide and mud guide are relatively troublesome. Summary of the Invention

[0004] The purpose of this invention is to provide a method for installing a photovoltaic frame. This method assembles the photovoltaic frame and the photovoltaic laminate together. While maintaining the basic load-bearing capacity of the photovoltaic panel against typhoons, it can avoid the problem of adhesive overflow and pollution during the assembly of the photovoltaic frame and the photovoltaic laminate. On the other hand, after assembly, a dust removal groove can be formed on the photovoltaic frame, which facilitates rainwater to carry away the dust on the photovoltaic module and ensure the output power of the photovoltaic module.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This invention discloses a method for installing a photovoltaic (PV) frame. The PV module includes a PV laminate and a PV frame. The PV frame surrounds the PV laminate and has a mounting groove. The PV laminate is adhered to the mounting groove. The method for installing the PV frame includes:

[0007] At least one pre-cut notch is made on the photovoltaic frame to form at least one pre-cut structure that can be removed from the photovoltaic frame;

[0008] Adhesive is poured into the mounting groove, and the photovoltaic laminate is pressed into the mounting groove;

[0009] After the adhesive has cured, the photovoltaic module is trimmed and cleaned.

[0010] The pre-cut structure is removed from the photovoltaic frame to form a cleaning groove;

[0011] The walls of the cleaning tank are cleaned to remove the adhesive adhering to the walls of the cleaning tank.

[0012] In some embodiments, the photovoltaic frame includes an integrally formed main body and an extension. The extension includes a first part and a second part. The first part is perpendicular to the second part, and the second part is spaced apart from the surface of the main body. The surfaces of the first part, the second part, and the main body together form the mounting groove. The pre-cut is made at the second part and at the connection between the second part and the first part.

[0013] In some specific embodiments, the pre-cut includes two first grooves spaced apart along the length of the photovoltaic frame and a second groove extending along the length of the photovoltaic frame.

[0014] In some more specific embodiments, the pre-cut structure includes a pre-cut body and a support column, with two first grooves located on both sides of the pre-cut body along the photovoltaic frame, one end of the support column being connected to the pre-cut body, and the other end being connected to the groove wall of the first groove and / or the second groove.

[0015] In some alternative embodiments, the support columns are arranged in pairs and connected to the groove wall of the second groove, and the two support columns arranged in pairs isolate the first groove and the second groove.

[0016] In some alternative embodiments, the support column is located in the middle of the pre-cut body and connected to the second groove, the support column dividing the second groove into two parts, the two parts of the second groove being connected to the two first grooves respectively.

[0017] In some alternative embodiments, the support columns are located on both sides of the pre-cut body and connected to the groove wall of the first groove, and the two first grooves are connected to the second groove.

[0018] In some specific embodiments, the depth of the first groove is greater than the thickness of the second portion.

[0019] In some embodiments, the pre-cut is processed by machining, laser cutting, or stamping.

[0020] In some embodiments, the adhesive includes any one of silicone, butyl rubber, or double-sided tape.

[0021] The beneficial effects of the photovoltaic frame installation method of the present invention are as follows: In the actual assembly process, a pre-cut slit is first set in the photovoltaic frame. The pre-cut structure within the pre-cut slit ensures that the entire photovoltaic frame will not deform and maintain its shape when the photovoltaic laminate is installed. The pre-cut structure can restrict the flow path of the adhesive, reduce the probability of adhesive overflow, and facilitate subsequent cleaning processes. After the photovoltaic frame and photovoltaic laminate are assembled, the presence of the pre-cut slit allows for easy removal of the pre-cut structure from the photovoltaic frame to form a cleaning groove. This facilitates rainwater carrying away dust from the photovoltaic module through the cleaning groove, ensuring the output power of the photovoltaic module.

[0022] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0034] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0036] First, it should be noted that existing photovoltaic (PV) frames with cleaning grooves exist. Due to the presence of these grooves, the PV frame is prone to deformation during assembly, and adhesive can easily overflow from the grooves. Therefore, installing such PV frames requires specialized tooling, which not only increases the manufacturing cost of the PV modules but also reduces the assembly efficiency of the PV frame.

[0037] This invention discloses a method for installing a photovoltaic (PV) frame. The PV module includes a PV laminate 200 and a PV frame 100. The PV frame 100 is arranged around the circumference of the PV laminate 200. The PV frame 100 has a mounting groove 160, and the PV laminate 200 is adhered to the mounting groove 160. Figure 1 As shown, the installation methods for photovoltaic frames include:

[0038] S1: At least one pre-cut notch 140 is made on the photovoltaic frame 100 to form at least one pre-cut structure 130 that can be removed from the photovoltaic frame 100. The structure of the photovoltaic frame 100 is referenced. Figure 2 As shown;

[0039] S2: Pour 300 g of adhesive into the mounting groove 160 (reference) Figure 3 (as shown), and press the photovoltaic laminate 200 into the mounting groove 160 (see reference). Figure 4 (as shown)

[0040] S3: After the adhesive 300 has cured, trim and clean the photovoltaic modules;

[0041] S4: Remove the pre-cut structure 130 from the photovoltaic frame 100 to form the cleaning groove 150 (reference) Figure 5 (as shown)

[0042] S5: Clean the walls of the cleaning tank 150 to remove the adhesive 300 adhering to the walls of the cleaning tank 150.

[0043] Understandably, during the actual assembly process, a pre-cut notch 140 is first set in the photovoltaic frame 100. The pre-cut structure 130 within the pre-cut notch 140 must ensure that the entire photovoltaic frame 100 does not deform and maintains its shape when the photovoltaic laminate 200 is installed. The pre-cut structure 130 can restrict the flow path of the adhesive 300, reducing the chance of adhesive 300 overflow and facilitating subsequent cleaning processes. After the photovoltaic frame 100 and photovoltaic laminate 200 are assembled, the pre-cut structure 130 can be easily removed from the photovoltaic frame 100 due to the presence of the pre-cut notch 140 to form a dust removal groove 150. This allows rainwater to carry away dust from the photovoltaic module through the dust removal groove 150, ensuring the output power of the photovoltaic module.

[0044] It should be noted that the number and location of the pre-cuts 140 can be determined based on factors such as the length of the photovoltaic frame 100 and the installation location of the photovoltaic control box. The pre-cuts 140 can be located at the lower end of the photovoltaic frame 100, or there can be symmetrical pre-cuts 140 on both the upper and lower surfaces of the photovoltaic frame 100. In the following description, the pre-cut 140 is described as one, located on the upper surface of the photovoltaic frame 100, and located at the lower part along the length direction of the photovoltaic frame 100.

[0045] In step S5, the walls of the cleaning tank 150 are cleaned. After removing the adhesive 300 adhering to the walls of the cleaning tank 150, the walls of the cleaning tank 150 can be polished to remove burrs, ensuring that the walls of the cleaning tank 150 are relatively smooth, thereby facilitating the discharge of sewage.

[0046] In some embodiments, reference Figure 2As shown, the photovoltaic frame 100 includes an integrally formed main body 110 and an extension 120. The extension 120 includes a first part 121 and a second part 122. The first part 121 and the second part 122 are arranged perpendicularly to each other. The second part 122 is spaced apart from the surface of the main body 110. The surfaces of the first part 121, the second part 122, and the main body 110 together form a mounting groove 160. A pre-cut 140 is formed at the second part 122 and at the connection between the second part 122 and the first part 121. It can be understood that the main body 110, as a structure supporting the photovoltaic laminate 200, has good strength and can stably support the photovoltaic laminate 200. The extension 120, as a structure for snapping onto the photovoltaic laminate 200, can ensure that the entire photovoltaic laminate 200 is stably snapped onto the photovoltaic frame 100, thereby ensuring the protection of the photovoltaic laminate 200 by the photovoltaic frame 100. Meanwhile, the pre-cut opening 140 is opened in the second part 122 and the connection between the second part 122 and the first part 121. That is, the pre-cut structure 130 includes a certain area of ​​the second part 122 and the position where the area is connected to the first part 121. This facilitates the formation of the cleaning trough 150 so that sewage can flow out. On the other hand, the first part 121 and the main body 110, which have a large area, are still used to snap the photovoltaic laminate 200, thereby ensuring the installation stability of the photovoltaic laminate 200.

[0047] In some specific embodiments, reference is made to Figure 2 As shown, the pre-cut 140 includes two first grooves 141 spaced apart along the length of the photovoltaic frame 100 and a second groove 142 extending along the length of the photovoltaic frame 100. It can be understood that the entire pre-cut 140 is formed as a U-shaped groove. In step S4, the pre-cut structure 130 can be easily removed from the photovoltaic frame 100 using pliers, facilitating operation by workers. Of course, in other embodiments of the present invention, the pre-cut 140 may also include only either the first groove 141 or the second groove 142. Since the wall thickness of the first portion 141 and the second portion 142 is relatively small, even with only one groove, the pre-cut structure 130 can be easily removed.

[0048] In some more specific embodiments, reference is made to Figure 2 , Figure 6 and Figure 7As shown, the pre-cut structure 130 includes a pre-cut body 131 and a support column 132. Two first grooves 141 are located on both sides of the pre-cut body 131 along the photovoltaic frame 100. One end of the support column 132 is connected to the pre-cut body 131, and the other end is connected to the groove wall of the first groove 141 and / or the second groove 142. It is understood that the pre-cut body 131 is used to reduce the probability of adhesive 300 overflow. The pre-cut body 131 has a large area. The support column 132 is used to ensure the connection between the pre-cut body 131 and the photovoltaic frame 100. On the one hand, this ensures that the pre-cut structure 130 will not easily separate from the photovoltaic frame 100 during assembly. On the other hand, after assembly, the operator only needs to cut the support column 132 to separate the pre-cut structure 130 from the photovoltaic frame 100, which is convenient for the user.

[0049] In some alternative embodiments, reference is made to Figure 2 As shown, multiple support columns 132 are provided and connected to the wall of the second groove 142. The multiple support columns 132 isolate the first groove 141 and the second groove 142. It can be understood that by having multiple support columns 132 isolate the first groove 141 and the second groove 142, and the first groove 141 and the second groove 142 are not connected, the connection between the pre-cut structure 130 and the photovoltaic frame 100 can be improved, and the phenomenon of the pre-cut structure 130 falling off the photovoltaic frame 100 during the assembly process can be avoided.

[0050] In some alternative embodiments, reference is made to Figure 6 As shown, the support column 132 is located in the middle of the pre-cut body 131 and is connected to the second groove 142. The support column 132 divides the second groove 142 into two parts, and the two parts of the second groove 142 are respectively connected to the two first grooves 141. It can be understood that, compared to... Figure 2 The structure shown in this embodiment, by providing a support column 132 to support the pre-cut body 131, makes it easier to remove the pre-cut structure 130 from the photovoltaic frame 100 after assembly. Furthermore, placing the support column 132 in the middle of the pre-cut body 131 also ensures, to a certain extent, the reliable connection between the pre-cut structure 130 and the photovoltaic frame 100.

[0051] In some alternative embodiments, reference is made to Figure 7 As shown, the support columns 132 are located on both sides of the pre-cut body 131 and connected to the groove wall of the first groove 141. The two first grooves 141 are connected to the second groove 142. It can be understood that, compared to... Figure 2The structure shown in this embodiment, by providing a support column 132 to support the pre-cut body 131, makes it easier to remove the pre-cut structure 130 from the photovoltaic frame 100 after assembly. The support column 132 is located on both sides of the pre-cut body 131 and is connected to the groove wall of the first groove 141, which also ensures the reliable connection between the pre-cut structure 130 and the photovoltaic frame 100 to a certain extent.

[0052] It should be noted that in other embodiments of the present invention, the shape, number, and distribution of the support columns 132 can be adjusted according to actual needs and are not limited to the above description.

[0053] In some specific embodiments, the depth of the first groove 141 is greater than the thickness of the second portion 122. It is understood that, compared to the first groove 141 being a through groove penetrating the second portion 122, the greater depth of the first groove 141 ensures a reliable connection between the pre-cut structure 130 and the photovoltaic frame 100, preventing the pre-cut structure 130 from falling off the photovoltaic frame 100 during assembly, and also facilitates the removal of the pre-cut structure 130 from the photovoltaic frame 100 after assembly. It should be noted that the difference between the depth of the first groove 141 and the thickness of the second portion 122 can be selected according to actual needs; therefore, the specific difference between the depth of the first groove 141 and the thickness of the second portion 122 is not described here.

[0054] In some embodiments, the pre-cut 140 is processed by machining, laser cutting, or stamping. Of course, in other embodiments of the present invention, the pre-cut 140 may also be manufactured using other processes depending on the actual situation.

[0055] Optionally, the processing technology of the photovoltaic frame 100 can be: aluminum profile cutting → aluminum profile anchor point connection → aluminum profile pre-cut 140 → packaging and warehousing, or it can be: aluminum profile cutting → aluminum profile anchor corner bracket connection → aluminum profile pre-cut 140 → packaging and warehousing.

[0056] In some embodiments, the adhesive 300 includes any one of silicone, butyl rubber, or double-sided tape. Of course, in other embodiments of the invention, the adhesive 300 may be selected from other materials as needed. It should be noted that if the adhesive 300 is double-sided tape, the step of adhesive 300 curing refers to the double-sided tape firmly bonding the photovoltaic frame 100 and the photovoltaic laminate 200 together under external pressure.

[0057] refer to Figure 8As shown, the manufacturing process of photovoltaic modules is as follows: cell cutting → front glass loading → front film laying → cell welding → cell panel layout → cell panel EL1 inspection → cell panel flipping → lead wire welding → back film laying → back glass / backsheet laying → lead wire arrangement → cell panel EL2 inspection → edge sealing tape fixing → lamination → edge trimming → frame assembly → junction box glue installation → junction box welding → curing → back cleaning → corner trimming → slot removal → IV testing → safety testing → EL3 testing → grading → packaging and warehousing.

[0058] The steps of the photovoltaic frame installation method provided by the present invention are covered in the above process. Specifically, step S1 of the embodiment of the present invention is the frame mounting step in the above process, step S2 of the embodiment of the present invention is the curing, back cleaning and corner trimming step in the above process, and steps S3-S4 of the embodiment of the present invention are the groove removal step in the above process.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
