Modes for Carrying Out the Invention

[0019] Exemplary embodiments shown in the accompanying drawings will be described in detail below. When the following description relates to the drawings, unless otherwise indicated, the same reference numerals in different drawings indicate the same or similar elements. The embodiments described in the following exemplary embodiment do not represent all embodiments that are consistent with the present invention. Rather, they are merely examples of devices and methods that are consistent with some aspects of the present invention, as detailed in the appended claims.

[0020] The solar power generation industry has developed rapidly, and solar power generation modules are widely used in various fields. In related technologies, a frame structure is manufactured using a thermosetting pressing process, but the thermosetting process is slow, and the manufacturing speed by pressing decreases. The demand for frames of solar power generation modules is gradually increasing, and manufacturing the frame structure using the thermosetting pressing process cannot meet the market demand, and the strength of the frame structure made of fiber is generally not high, raising concerns about safety.

[0021] Currently, the only way to compensate for the lack of production speed is to expand the plant building and increase equipment, resulting in increased energy consumption and equipment investment.

[0022] The present disclosure relates to a frame structure of a solar power generation module for attaching a photovoltaic structure. The frame structure is elongated, made of a reinforced fiber resin composite material, and includes a support arm extending in a first direction, a first mounting arm, a second mounting arm, and a third mounting arm attached to the same side of the support arm, and a fourth mounting arm connecting the second mounting arm and the third mounting arm. The first mounting arm, the second mounting arm, and the third mounting arm all extend in a second direction and are sequentially arranged in the first direction. The first direction is perpendicular to the second direction, and both the first direction and the second direction are perpendicular to the extending direction of the frame structure. The support arm has a first support structure and a second support structure fixedly connected to the first support structure. The first mounting arm, the second mounting arm, and the first support structure surround a mounting groove for attaching the photovoltaic structure, and the second mounting arm, the third mounting arm, and the fourth mounting arm and the second support structure surround a connection groove for attaching a connection angle. Reinforcing ribs are provided on the inner walls of the mounting groove and the connection groove, thereby providing a frame structure of a solar power generation module. The present disclosure manufactures the frame structure using a reinforced fiber resin composite material made of reinforced fibers and a photocurable resin, and provides reinforcing ribs on the inner walls of the mounting groove and the connection groove, so that the frame structure has high strength, good tensile and flexural resistance, strong load-bearing capacity, and can be manufactured by a photocuring pressing process, which greatly improves the speed and production efficiency compared with the thermosetting pressing process in related technologies.

[0023] According to one exemplary embodiment, as shown in FIG. 1, the present disclosure provides a frame structure of a solar power generation module for attaching a photovoltaic structure. The frame structure is elongated (e.g., formed by an extrusion process, and the elongated extending direction is the extrusion manufacturing direction) and made of a reinforced fiber resin composite material.

[0024] In this embodiment, the frame structure includes a support arm 1 extending in the first direction (the X direction shown in FIG. 1), a first mounting arm 2, a second mounting arm 3, and a third mounting arm 4 attached to the same side of the support arm 1, and a fourth mounting arm 5 connecting the second mounting arm 3 and the third mounting arm 4. The first mounting arm 2, the second mounting arm 3, and the third mounting arm 4 all extend in the second direction (the Y direction shown in FIG. 1) and are sequentially arranged in the first direction. The first direction is perpendicular to the second direction, and the first direction and the second direction are respectively perpendicular to the extending direction of the frame structure. The support arm 1 has a first support structure 11 and a second support structure 12 fixedly connected to the first support structure 11. The first mounting arm 2, the second mounting arm 3, and the first support structure 11 surround a mounting groove 6 for mounting a photovoltaic structure. The second mounting arm 3, the third mounting arm 4, the fourth mounting arm, and the second support structure 12 surround a connection groove 7 for mounting a connection angle (not shown). Reinforcing ribs are provided on the inner wall of the mounting groove 6. By providing the reinforcing ribs, the support strength of the mounting groove 6 is improved, and reinforcing ribs may be provided on the inner wall of the connection groove 7 to improve the connection strength of the connection groove 7.

[0025] The connection strength of the frame structure is, that is, the snap engagement strength between the frame structure and the connection angle, and the support strength of the frame structure is, that is, the support strength of the frame structure for the photovoltaic structure. Referring to FIGS. 1 to 3, the reinforcing ribs may be provided, for example, in the middle portions of the first support structure 11, the second support structure 12, and the respective mounting arms. Thereby, when excessive pressure of the photovoltaic structure on the mounting arm occurs, it is possible to avoid the middle portion of the mounting arm from bending or breaking. Taking the second support structure 12 as an example, the second support structure 12 can provide a supporting force for a photovoltaic structure (not shown) in the first direction (the X direction shown in FIG. 1). When the photovoltaic structure is too heavy, the middle portion of the second support structure 12 may be warped downward or upward. By providing a first reinforcing rib 71 in the middle portion of the second support structure 12, the thickness of the middle portion of the second support structure 12 is increased, and the bending rigidity is improved.

[0026] The composite material in this embodiment is a fiber-reinforced resin composite material made by physically mixing reinforcing fibers and a photocurable resin. For example, a reinforcing fiber bundle composed of a plurality of reinforcing fibers enters a sizing device, and the sizing device discharges a liquid photocurable resin toward the reinforcing fiber bundle. The photocurable resin can be impregnated between different reinforcing fiber bundles. The photocurable resin is irradiated by a curing device and cured to bond the plurality of reinforcing fibers. Here, the reinforcing fibers may be any one or a combination of glass fibers, carbon fibers, synthetic fibers, mineral fibers, and mixed fibers, and the photocurable resin may be any one or a combination of epoxy acrylate, urethane acrylate, polyester acrylate, and unsaturated polyester resin.

[0027] In this embodiment, by manufacturing a frame structure using a fiber-reinforced resin composite material made of reinforcing fibers and a photocurable resin, the frame structure has high strength, good tensile and flexural resistance, strong load-bearing capacity, and by manufacturing it through a photocuring pressing process, compared with the thermosetting pressing process in related technologies, the speed is significantly improved and the production efficiency is improved.

[0028] In one embodiment, referring to FIGS. 1 and 2, the fourth mounting arm 5 may be provided parallel to the support arm 1, that is, the fourth mounting arm 5 is perpendicular to the third mounting arm 4, and the fourth mounting arm 5 is perpendicular to the second mounting arm 3. In another example, referring to FIG. 3, a structure in which the fourth mounting arm 5 is inclined relative to the support arm 1, that is, the fourth mounting arm 5 is not perpendicular to the third mounting arm 4 and the fourth mounting arm 5 is not perpendicular to the second mounting arm 3 can disperse the supporting force of the third mounting arm 4 and improve the supporting strength.

[0029] In one embodiment, as shown in FIG. 1, two first reinforcing ribs 71 provided on the fourth mounting arm 5 and the second support structure 12 respectively are provided on the inner wall of the connecting groove 7 in this embodiment. By providing the first reinforcing ribs 71 on the second support structure 12 and the fourth mounting arm 5, the thickness of the middle part of the second support structure 12 and the fourth mounting arm 5 is increased, and when the second support structure 12 and the fourth mounting arm 5 receive pressure from the photovoltaic structure, they are prevented from bending, and the support strength of the frame structure for the photovoltaic structure is improved.

[0030] As shown in FIG. 4, a first connecting beam 72 may be further provided in the connecting groove 7 in this embodiment. The first connecting beam 72 connects the fourth mounting arm 5 and the two first reinforcing ribs 71 on the second support structure 12, and further divides the inside of the closed connecting groove 7 into two chambers that do not communicate with each other. In this embodiment, by providing the first connecting beam 72 that connects the middle region between the fourth mounting arm 5 and the second support structure 12 in the closed connecting groove 7, the strength of the middle region between the second support structure 12 and the fourth mounting arm 5 is further reinforced compared to providing the first reinforcing ribs 71 separately on the second support structure 12 and the fourth mounting arm 5. When the second support structure 12 and the fourth mounting arm 5 receive pressure from the photovoltaic structure, they are prevented from bending, and the load-bearing capacity of the frame structure is improved. A plurality of parallel first connecting beams 72 may be provided in the connecting groove 7.

[0031] As shown in FIG. 5, a plurality of second connecting beams 73 may be further provided in the connecting groove 7 in this embodiment. The plurality of second connecting beams 73 are provided intersectingly, and each of the second connecting beams 73 connects the diagonal positions of the connecting groove 7, thereby dividing the connecting groove 7 with a rectangular inner contour into a plurality of triangular chambers, improving the strain resistance of each mounting arm surrounding the connecting groove 7, and thereby improving the support strength of the frame structure for the photovoltaic structure.

[0032] Referring to FIGS. 4 and 5, in this embodiment, in the second direction (the Y direction shown in FIG. 1), both ends of the second mounting arm 3 and the third mounting arm 4 protrude from the support arm 1 and the fourth mounting arm 5. As a result, the cross-section of the frame structure presents an I-shaped structure, increasing the contact area between the third mounting arm 4 and the mounting structure (not shown) and the contact area of the second mounting arm 3 with respect to the photovoltaic structure, reducing the pressure per unit area, and improving the load-bearing capacity of the frame structure. Here, the mounting structure such as a roof or the ground is an area where the photovoltaic structure can be installed.

[0033] In this embodiment, as shown in FIG. 6, a second reinforcing rib 61 is provided on the inner wall of the mounting groove 6. In one example, the second reinforcing rib 61 is provided at the central part of the first support structure 11. By providing the second reinforcing rib 61 at the central part of the first support structure 11, it is equivalent to thickening the thickness of the central part of the first support structure 11, improving the bending rigidity of the first support structure 11, and avoiding the photovoltaic structure (not shown) from falling off due to the first support structure 11 being bent (cracked). In another example, the second reinforcing rib 61 may be provided on the first mounting arm 2. By providing the second reinforcing rib 61 on the first mounting arm 2, the bending rigidity of the first mounting arm 2 can be improved, and the falling off of the power generation structure due to the bending (breaking) of the first mounting arm 2 can be avoided.

[0034] In one embodiment, as shown in FIGS. 1 to 5, an overhanging groove 62 penetrating the frame structure in the extending direction of the frame structure is provided on the side where the first mounting arm 2 and the second mounting arm 3 face each other. By providing the overhanging groove 62, excess rubber will flow out through the overhanging groove 62 during coating, avoiding the rubber from contaminating the photovoltaic structure (not shown).

[0035] Referring to FIG. 3, when the second reinforcing rib 61 is provided on the inner wall of the mounting groove 6, the second reinforcing rib 61 forms irregularities on the side surface of the first support structure 11 which is the inner wall of the mounting groove 6, and also forms irregularities on the side surface of the first mounting arm 2 which is the inner wall of the mounting groove 6. The convex part is the second reinforcing rib 61, and the concave part can form the protruding groove 62. Thereby, the excess rubber flows out through the protruding groove 62, and it is avoided that the rubber contaminates the photovoltaic structure.

[0036] The second reinforcing rib 61 may be provided only on the first support structure 11, may be provided only on the first mounting arm 2, or may be provided on both the first support structure 11 and the first mounting arm 2.

[0037] In one embodiment, referring to FIG. 1, in the frame structure according to this embodiment, a notch is provided in the fourth mounting arm 5 to form two short fourth mounting arms 5, thereby forming an opening in the connecting groove 7 to expose the inner wall of the connecting groove 7, so that the curing light of the curing device can irradiate the inner wall of the connecting groove 7. By irradiating more photocurable resin, the curing speed in the manufacturing process of the frame structure is improved, and only one photocuring lamp is used in the curing device to provide the curing light, thus saving costs.

[0038] In one embodiment, as shown in FIGS. 1, 4, and 5, the connecting groove 7 according to this embodiment further includes a chamfer structure 8, and the chamfer structure 8 has a rounded structure. Referring to FIG. 1, the chamfer structure 8 may be provided on the inner wall and the outer wall of the closed connecting groove 7. In one example, referring to FIG. 1, the chamfer structure 8 on the inner wall of the connecting groove 7 is provided at the connection between the second mounting arm 3 and the second support structure 12, the connection location between the second mounting arm 3 and the fourth mounting arm 5, the connection location between the third mounting arm 4 and the second support structure 12, the connection location between the third mounting arm 4 and the fourth mounting arm 5, and both sides of the first reinforcing rib 71. In one example, as shown in FIG. 1, the chamfer structure 8 on the outer wall of the connecting groove 7 is provided at the connection location between the second mounting arm 3 and the fourth mounting arm 5. In this embodiment, by providing the chamfer structure 8, the thickness at the corner position of the closed connecting groove 7 is increased, improving the structural strength. At the same time, due to the rounded structure, when the frame structure contacts the mounting structure (not shown) and the connecting angle, and when the frame structure contacts the photovoltaic structure, there is no stress concentration, improving the strain resistance.

[0039] In other possible embodiments, as shown in FIGS. 1 and 4, chamfer structures may be provided on the inner wall and the outer wall of the mounting groove 6. For example, referring to FIG. 4, at the connection location between the first mounting arm 2 and the first support structure 11, chamfer structures 8 are provided on both the inner wall and the outer wall of the mounting groove 6. The chamfer structure 8 increases the thickness at the connection location, avoiding the detachment of the photovoltaic structure due to the warping of the first mounting arm 2.

[0040] According to one exemplary embodiment, as shown in FIG. 7, the present disclosure further provides a drawing and pressing manufacturing process, and the drawing and pressing process includes the following steps:

[0041] Step S100 of the yarn feeding device sending the fiber yarn to the sizing device In this step, the fiber yarns are arranged in the yarn feeding device according to a predetermined specification, and one end of the fiber yarns penetrates through the sizing device and the forming device and is connected to a traction device that can move the fiber yarns in the drawing and manufacturing system at a predetermined speed. When passing through the forming device, the fiber yarns are pressed against a frame structure with a preset shape. Note that the fiber yarns are reinforcing fibers and may be, for example, any one or a combination of multiple types among glass fibers, carbon fibers, synthetic fibers, mineral fibers, and hybrid fibers.

[0042] Step S200 where the fiber yarns enter the sizing device and the resin in the sizing device impregnates the fiber yarns to form a composite material In this step, in one example, multiple fiber yarns enter the sizing device, and the sizing device sprays the resin onto the fiber yarns by the shower method, allowing the resin to penetrate into the gaps between each fiber yarn and bonding the multiple fiber yarns. In another example, the multiple fiber yarns may be impregnated with the resin, and it is also possible for the resin to penetrate into the gaps between each fiber yarn.

[0043] Here, the resin in the sizing device is a photocurable resin, which is, for example, any one or a combination of multiple types among epoxy acrylate, urethane acrylate, polyester acrylate, and unsaturated polyester resin, and the viscosity of the photocurable resin is 1000 cp or less. The photocurable resin can be rapidly cured by irradiation with ultraviolet light from a curing lamp. Since the photocurable resin has a faster curing speed than thermoplastic resins and thermosetting resins, by using the photocurable resin and the photocuring process to manufacture the frame structure, the manufacturing speed by drawing can be greatly improved.

[0044] Step S300 where the composite material passes through the mold and is pressed against a frame structure with a preset shape in the mold In this step, a cavity is provided in the forming device, and the cavity gradually becomes smaller along the drawing direction. The shape of the cavity at the outlet end of the forming device is the cross-sectional shape of the frame structure.

[0045] In an embodiment of the present disclosure, the cavity of the molding device is adjusted such that the connecting groove of the extruded frame structure has a notch. When the frame structure with the notch is irradiated by ultraviolet rays, the inner wall of the connecting groove is irradiated and rapid curing becomes possible, improving the pushing speed of the photocuring pushing system.

[0046] Step S400 in which the frame structure passes through a curing device that emits curing light and irradiates the frame structure In this step, during the process of the frame structure passing through the curing device, the main curing lamp of the curing device is provided directly above the frame structure, and the notch of the frame structure is also located above. Therefore, the curing light emitted by the main curing lamp first passes through the notch downward and directly irradiates the inner wall of the connecting groove, irradiating more surfaces of the frame structure, and significantly improving the curing speed.

[0047] Step S500 in which the traction device moves the frame structure to perform pushing production In this step, the traction device can convey the frame structure at a preset speed. The preset speed is, for example, 5 m / min to 50 m / min.

[0048] In one embodiment, step S100 in the above-described embodiment further includes Step S110 in which the yarn feeding device feeds yarn to the sizing device at a preset feeding amount.

[0049] In this step, the amount of fiber yarn supplied by the yarn feeding device to the sizing device needs to ensure that the mass percentage of the fiber yarn in the composite material is 60% to 86% and the mass percentage of the resin is 14% to 40%. The frame structure formed using such a composite material has high strength, good tensile and flexural resistance, and strong load-bearing capacity.

[0050] In one embodiment, step S200 in the above-described embodiment further includes Step S210 of preparing resin at a preset ratio.

[0051] In this step, the resin of the composite material can be manufactured by mixing a host resin, a diluent, an auxiliary agent, an initiator, etc. as raw materials.

[0052] Here, the preset ratio is 40 to 60 parts by weight of the host resin, 30 to 50 parts by weight of the diluent, 1 to 10 parts by weight of the auxiliary agent, and 1 to 3 parts by weight of the initiator. The resin manufactured at this ratio does not exceed a viscosity of 500 cp, can impregnate between a plurality of fiber yarns at a faster impregnation rate, and the impregnation is sufficient. When the impregnation rate of the resin into the fiber yarns increases, the traction device can increase the traction speed, and thus the manufacturing speed by drawing can be increased.

[0053] Note that the host resin may be, for example, one or more of epoxy acrylate, modified epoxy acrylate, urethane acrylate, polyester acrylate, and unsaturated polyester resin. The reactive monomer diluent is a monomer containing one or two carbon-carbon double bond functional groups, such as isobornyl acrylate (IBOA), acryloyl morpholine (ACMO), 2-phenoxyethyl acrylate (PHEA), 1,6-hexanediol diacrylate (HDDA), dipropylene glycol diacrylate (DPGDA). The auxiliary agent is a monomer containing two or more carbon-carbon double bond functional groups, such as ethoxylated trimethylolpropane triacrylate (THEICTA), tris(2-hydroxyethyl) isocyanurate triacrylate (TMP3POTA). The initiator is a radical photoinitiator having UV activity, such as 1-hydroxycyclohexyl phenyl ketone (HCPK), 2-hydroxy-2-methyl-1-phenylpropanone (HMPP), benzoin diethyl ether (DMPA), phenylbis(2,4,6-trimethylbenzoyl) phosphine oxide (BAPO).

[0054] In one exemplary embodiment, after the completion of step S400, the drawing manufacturing process further The shower device includes step S410 of spraying an overcoat layer on the surface of the frame structure.

[0055] In this step, the shower head can be installed around the frame structure, and the overcoat layer can be sprayed on the surface of the frame structure.

[0056] In this embodiment, after spraying the overcoat layer on the frame structure, the drawing and pressing manufacturing process further includes step S420 in which the heating device heats the frame structure to bake the overcoat layer.

[0057] In one exemplary embodiment, after the completion of step S500, the drawing and pressing manufacturing process further includes step S600 in which the cutting device cuts the frame structure according to a preset specification.

[0058] In this step, the frame structure passing through the traction device on the production line can be used only after being cut. Here, the preset specification includes the cutting length and the cutting angle. The cutting length, that is, the length and width of the photovoltaic structure, needs to be selected and set according to the customer's requirements. The cutting angle, that is, the frame shape of the photovoltaic structure, for example, in the case of a frame structure for mounting a rectangular photovoltaic structure, the cutting angle is 45°, and in the case of a frame structure for mounting a regular hexagonal photovoltaic structure, the cutting angle is 60°.

[0059] Other embodiments of the present disclosure will be readily apparent to those skilled in the art upon consideration of this specification and the embodiments disclosed herein. The present disclosure is intended to cover any variations, uses, or adaptations of the present disclosure, including known common general knowledge or conventional technical means in the technical field not disclosed by the present disclosure, in accordance with the general principles of the present disclosure.
