Description

[0001] This application is a divisional application of the patent application with the application date of November 15, 2022, named "A framing method for non-full-frame photovoltaic modules" and application number 202211430494.8. Technical Field

[0002] The present invention relates to the technical field of photovoltaic module installation, and in particular to a framing method for a non-full-frame photovoltaic module. Background Art

[0003] Among the existing photovoltaic modules, due to considerations such as design, mass production and appearance, most photovoltaic modules are generally full-frame. After market selection, the proportion of frameless photovoltaic modules has tended to be stable, while non-full-frame photovoltaic modules also have a certain market in some special environments, such as unconventional screw hole installation or non-block installation. Non-full-frame photovoltaic modules also have a market in BIPV (Building Integrated Photovoltaic) and sea floating module markets.

[0004] However, single-section or segmented non-full-frame photovoltaic modules have the problem of difficult positioning during the manufacturing and installation process. Currently, the framing of non-full-frame photovoltaic modules is mostly done by using tooling for positioning, and then manually framing. When using tooling for positioning, the tooling is mostly aligned with the two ends of the photovoltaic laminate. The positioning accuracy of the single-section or segmented frame and the photovoltaic laminate depends on the placement accuracy of the tooling. In the process of installing the frame multiple times, the tooling may be displaced, resulting in deviations in the positioning of the single-section or segmented frame and the photovoltaic laminate, affecting the installation size of the photovoltaic module; at the same time, when manually framing, the tooling is mostly placed on the module or needs to be held for a long time. The sealant or structural adhesive in the frame groove is easy to stick to the tooling, causing secondary contamination to the frame. In addition, when using sealant or structural adhesive to bond the photovoltaic laminate and the frame, the sealant or structural adhesive is easy to overflow from the frame installation groove and form lumps on the upper and lower surfaces of the photovoltaic laminate, thereby affecting the cleanliness of the module. Summary of the Invention

[0005] In order to solve at least one technical problem in the prior art, the present invention provides a framing method for a non-full-frame photovoltaic module.

[0006] To achieve the above-mentioned purpose, the present invention adopts a technical solution: a framing method for a non-full-frame photovoltaic module, comprising the following steps:

[0007] Placing a positioning tool on the upper surface of the laminate fixed on the framing platform for pre-positioning, wherein the positioning tool has one or more positioning notches;

[0008] affixing a single-sided foam tape to the edge of the laminate below the positioning notch;

[0009] A segmented frame with silicone coated on the inner wall of the installation groove is clamped on the outside of the single-sided foam tape.

[0010] In some embodiments, the positioning tool includes a positioning plate, and a first positioning block and a second positioning block fixed on the positioning plate, the length of the positioning plate is equal to the side length of the frame to be installed of the laminate, and one long side of the positioning plate is provided with one or more positioning notches recessed toward the other long side, and the position of the positioning notches corresponds to the position of the segmented frame installed on the laminate; the first positioning block is fixed to the short side of the positioning plate and protrudes from a flat surface of the positioning plate; the second positioning block is fixed to a long side of the positioning plate and protrudes from the positioning plate in the same direction as the first positioning block.

[0011] In some embodiments, the steps of pre-positioning using the positioning tool are as follows: placing the positioning tool on the upper surface of the laminate with the first positioning block facing the laminate and the positioning notch facing the edge of the laminate for installing the segmented frame, and moving the positioning tool so that the second positioning block and the first positioning block are respectively against the two edges of the laminate.

[0012] In some embodiments, the step of sticking the single-sided foam tape to the edge of the laminate is as follows: sticking at least two of the single-sided foam tapes in a "[" shape to the edge of the laminate located below the positioning notch, wherein the outer edges of two of the single-sided foam tapes are respectively adjacent to the two side walls of the positioning notch.

[0013] In some embodiments, the steps for clamping the segmented frame on the outside of the single-sided foam tape are as follows: remove the positioning tool, and clamp the segmented frame with the inner wall of the installation groove coated with silicone on the edge of the laminate and the outside of the single-sided foam tape in a manner such that the two ends of the installation groove are flush with the outer edge of the single-sided foam tape.

[0014] In some embodiments, the positioning notch is rectangular, and the length of the positioning notch is equal to the length of the segmented frame.

[0015] In certain embodiments, the single-sided foam tape has a release film, and the release film is located on the outer side of the single-sided foam tape facing away from the laminate.

[0016] In some embodiments, the single-sided foam tape extends the mounting groove of the segmented frame in a direction toward the laminate.

[0017] In certain embodiments, the single-sided foam tape is a PVC foam tape.

[0018] The beneficial effects of the present invention are:

[0019] (1) Use positioning tooling to pre-position the laminated parts. The pre-positioning operation is simple and the positioning is accurate.

[0020] (2) Using a single-sided foam tape with an isolation film to connect the laminate and the frame, the foam tape does not need to be cured, which shortens the installation time of the photovoltaic module, and the foam tape will not form lumps on the surface of the laminate;

[0021] (3) The foam tape can buffer the extrusion of the frame installation groove on the laminate, protecting the laminate from the extrusion damage of the frame;

[0022] (4) The installation method of the present invention is applicable to laminates of any glass thickness and is also applicable to all frames with installation grooves and no limit on the frame cross-section. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In the following description, many specific details are set forth to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0030] Reference Figures 1 to 3 , provides a framing method for a non-full-frame photovoltaic module, comprising the following steps:

[0031] Place a positioning tool 1 on the upper surface of the laminate 2 fixed on the framing platform for pre-positioning, wherein the positioning tool has one or more positioning notches 10;

[0032] Attach the single-sided foam tape 3 to the edge of the laminate 2 below the positioning notch 10;

[0033] The segmented frame 4 with the inner wall of the installation groove coated with silicone is clamped on the outside of the single-sided foam tape 3.

[0034] The method of this embodiment is applicable to laminates 2 with any glass thickness, such as laminates 2 with glass thickness of 3.2mm, 2.8mm, 2.5mm, 2.0mm, 1.6mm, 1.5mm, 1.2mm and 1.0mm, etc., and is also applicable to all segmented frames 4 with installation grooves and unlimited frame cross-section.

[0035] To implement the installation method disclosed herein, in one embodiment, please refer to Figure 2 , a positioning tool 1 is provided, comprising a positioning plate 11 having a side length equal to that of the segmented frame 4 installed on the laminate 2, a first positioning block 12 and a second positioning block 13 fixed on the positioning plate 11, one long side of the positioning plate 11 is provided with one or more positioning notches 10 recessed toward the other long side, and the position of the positioning notch 10 provided on the positioning plate 11 corresponds to the position of the segmented frame 4 installed on the laminate 2. The positioning notch 10 is rectangular, the length of the positioning notch 10 is equal to the length of the segmented frame 4, and the depth of the positioning notch 10 is slightly greater than the depth of the notch of the installation groove of the segmented frame 4. The first positioning block 12 is fixed on a short side of the positioning plate 11 and the first positioning block 12 protrudes from a flat surface of the positioning plate 11. The second positioning block 13 is fixed on the long side of the positioning plate 11 provided with the positioning notch 10 and protrudes from the positioning plate 11 in the same direction as the first positioning block 12.

[0036] In one embodiment, the steps for pre-positioning using the positioning tool 1 are as follows: the positioning tool 1 is placed on the upper surface of the laminate 2 in a manner such that the first positioning block 12 faces the laminate 2 and the positioning notch 10 faces the edge of the segmented frame 4 for installing the laminate 2, and the positioning tool 1 is moved so that the second positioning block 13 and the first positioning block 12 are respectively against the two edges of the laminate 2.

[0037] Since the position of the positioning notch 10 of the positioning tool 1 corresponds to the position where the segmented frame 4 is installed on the laminate 2, when the second positioning block 13 and the first positioning block 12 respectively abut against the two edges of the laminate 2, the position of the laminate 2 below the positioning notch 10 is the installation position of the segmented frame 4.

[0038] In one embodiment, a handle 14 is fixed on the other flat surface of the positioning tool 1 , and the positioning tool 1 is moved by holding the handle 14 .

[0039] In one embodiment, the step of sticking the single-sided foam tape 3 to the edge of the laminate 2 is as follows: stick at least two single-sided foam tapes 3 in a "[" shape to the edge of the laminate 2 below the positioning notch 10, wherein the outer side surfaces of two single-sided foam tapes 3 are respectively adjacent to the two side walls of the positioning notch 10.

[0040] In one embodiment, the steps for clamping the segmented frame 4 on the outside of the single-sided foam tape 3 are as follows: first remove the positioning tool 1 from the laminate 2, and then clamp the segmented frame 4 with silicone coated on the inner wall of the installation groove to the edge of the laminate 2 and the outside of the single-sided foam tape 3 in a way that the two ends of the installation groove are flush with the outer edges of the single-sided foam tape 3.

[0041] In one embodiment, the single-sided foam tape 3 has an isolation film, which is located on the outer side of the single-sided foam tape 3 facing away from the laminate 2. After the single-sided foam tape 3 is pasted on the edge of the laminate 2, the isolation film of the single-sided foam tape 3 is not torn off.

[0042] In one embodiment, the single-sided foam tape 3 adhered to the upper and lower surfaces of the laminate 2 extends the installation groove of the segmented frame 4 toward the laminate. In this way, when the installation groove of the segmented frame 4 is clamped on the outside of the single-sided foam tape 3, the single-sided foam tape 3 can buffer the extrusion of the end face of the installation groove of the segmented frame 4 on the laminate 2, thereby protecting the laminate 2 from damage caused by the extrusion of the segmented frame 4.

[0043] In one embodiment, the single-sided foam tape 3 is a PVC foam tape.
