Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module installation, and particularly to a method for framing a non-full-frame photovoltaic module. Background Art

[0002] In existing photovoltaic modules, due to considerations in terms of design, mass production, and appearance, most photovoltaic modules are full-frame. After market selection, the proportion of frameless photovoltaic modules has tended to stabilize. Non-full-frame photovoltaic modules also have a certain market in some special environments, such as in environments with unconventional screw hole installation or non-press block installation. Moreover, non-full-frame photovoltaic modules also have a market in the BIPV (Building Integrated Photovoltaic) and floating sea surface module markets.

[0003] However, there is a problem of difficult positioning during the manufacturing and installation of single-segment or segmented non-full-frame photovoltaic modules. Currently, when framing non-full-frame photovoltaic modules, fixtures are mostly used for positioning, and then manual framing is carried out. When using fixtures for positioning, the fixtures are mostly aligned with both ends of the photovoltaic laminate. The positioning accuracy of the single-segment or segmented frame and the photovoltaic laminate depends on the placement accuracy of the fixture. During the process of installing the frame multiple times, the fixture may shift, resulting in deviation in the positioning of the single-segment or segmented frame and the photovoltaic laminate, affecting the installation dimensions of the photovoltaic module. At the same time, during manual framing, the fixture is mostly placed on the module or needs to be held for a long time, and the sealant or structural adhesive at the frame slot is likely to stick to the fixture, causing secondary pollution to the frame. Also, when using sealant or structural adhesive to bond the photovoltaic laminate and the frame, the sealant or structural adhesive is likely to overflow from the installation slot of the frame and form lumps on the upper and lower surfaces of the photovoltaic laminate, thus affecting the cleaning of the module. Summary of the Invention

[0004] To solve at least one technical problem of the existing technology, the present invention provides a method for framing a non-full-frame photovoltaic module.

[0005] To achieve the above-mentioned invention purpose, the technical solution adopted by the present invention is: A method for framing a non-full-frame photovoltaic module, comprising the following steps:

[0006] Place the positioning tooling on the upper surface of the laminate fixed on the framing platform for pre-positioning. Among them, the positioning tooling 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 border to be installed on the laminate. One long side of the positioning plate is provided with one or more positioning notches recessed towards the other long side, and the position where the positioning notches are opened corresponds to the position where the segmented border of the laminate is installed; the first positioning block is fixed on the short side of the positioning plate and protrudes from one flat surface of the positioning plate; the second positioning block is fixed on one long side of the positioning plate and protrudes from the positioning plate in the same direction as the first positioning block.

[0007] Paste the single-sided foam tape on the edge of the laminate located below the positioning notch.

[0008] Clamp the segmented border with silicone coated on the inner wall of the installation groove outside the single-sided foam tape.

[0009] The steps of pre-positioning with the positioning tooling are as follows: Place the positioning tooling on the upper surface of the laminate with the first positioning block facing the laminate and the positioning notch facing the edge where the segmented border of the laminate is installed, and move the positioning tooling so that the second positioning block and the first positioning block respectively abut against two edges of the laminate.

[0010] In some embodiments, the steps of pasting the single-sided foam tape on the edge of the laminate are as follows: Paste at least 2 single-sided foam tapes on the edge of the laminate located below the positioning notch in a "[" shape, and the outer sides of 2 single-sided foam tapes are respectively adjacent to the two side walls of the positioning notch.

[0011] In some embodiments, the steps of clamping the segmented border outside the single-sided foam tape are as follows: Remove the positioning tooling, and clamp the segmented border with silicone coated on the inner wall of the installation groove on the edge of the laminate and outside the single-sided foam tape with the two ends of the installation groove flush with the outer side of the single-sided foam tape.

[0012] In some embodiments, the positioning notch is rectangular, and the length of the positioning notch is equal to the length of the segmented border.

[0013] In some 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.

[0014] In some embodiments, the single-sided foam tape extends out of the installation groove of the segmented border in the direction facing the laminate.

[0015] In some embodiments, the single-sided foam tape is a PVC foam tape.

[0017] (1) The positioning tooling is used to pre-position the laminate, and the pre-positioning operation is simple and accurate.

[0018] (2) The single-sided foam tape with an isolation film is used 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.

[0019] (3) The foam tape can buffer the extrusion of the frame installation notch on the laminate and protect the laminate from being damaged by the extrusion of the frame.

It should be noted that, without conflict, the embodiments and features in the embodiments in the present application can be combined with each other.

[0027] Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0028] Refer to Figures 1 to 3, a method for framing a non-full-frame photovoltaic module is provided, including the following steps:

[0029] Place the positioning tooling 1 on the upper surface of the laminate 2 fixed on the framing platform for pre-positioning. Among them, the positioning tooling has one or more positioning notches 10;

[0030] Paste the single-sided foam tape 3 on the edge of the laminate 2 below the positioning notch 10;

[0031] Clamp the segmented frame 4 with silicone coated on the inner wall of the installation groove outside the single-sided foam tape 3.

[0032] The method of this embodiment is applicable to laminates 2 with any glass thickness, such as laminates 2 with glass thicknesses 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-sections.

[0033] To implement the installation method of the present disclosure, in one embodiment, please refer to Figure 2 , a positioning tooling 1 is provided, including a positioning plate 11 with the same length as the side of the laminate 2 where the segmented frame 4 is installed, 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 towards the other long side. The position where the positioning plate 11 is provided with the positioning notches 10 corresponds to the position where the laminate 2 installs the segmented frame 4. 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 notch depth of the installation groove of the segmented frame 4. The first positioning block 12 is fixed on one 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.

[0034] In one embodiment, the steps of pre-positioning with the positioning tooling 1 are as follows: Place the positioning tooling 1 on the upper surface of the laminate 2 with the first positioning block 12 facing the laminate 2 and the positioning notch 10 facing the edge where the segmented frame 4 is installed on the laminate 2, and move the positioning tooling 1 so that the second positioning block 13 and the first positioning block 12 are respectively abutted against the two edges of the laminate 2.

[0035] Since the position where the positioning tooling 1 is provided with the positioning notches 10 corresponds to the position where the laminate 2 installs the segmented frame 4, when the second positioning block 13 and the first positioning block 12 are respectively abutted 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.

[0036] In one embodiment, a handle 14 is fixed on another flat surface of the positioning tooling 1, and the positioning tooling 1 is moved by holding the handle 14.

[0037] In one embodiment, the steps of pasting the single-sided foam tape 3 on the edge of the laminate 2 are as follows: at least two single-sided foam tapes 3 are pasted on the edge of the laminate 2 located below the positioning notch 10 in a "[" shape, and the outer sides of two of the single-sided foam tapes 3 are respectively adjacent to the two side walls of the positioning notch 10.

[0038] In one embodiment, the steps of clamping the segmented frame 4 outside the single-sided foam tape 3 are as follows: first, the positioning tooling 1 is removed from the laminate 2, and then the segmented frame 4 with silicone coated on the inner wall of the installation groove is clamped on the edge of the laminate 2 and outside the single-sided foam tape 3 in such a way that the two ends of the installation groove are flush with the outer side of the single-sided foam tape 3.

[0039] In one embodiment, the single-sided foam tape 3 has a release film, the release film is located on the outer side of the single-sided foam tape 3 facing away from the laminate 2, and after the single-sided foam tape 3 is pasted on the edge of the laminate 2, the release film of the single-sided foam tape 3 is not torn off.

[0040] In one embodiment, the single-sided foam tapes 3 pasted on the upper and lower surfaces of the laminate 2 extend out of the installation groove of the segmented frame 4 in the direction towards the laminate. In this way, when the installation groove of the segmented frame 4 is clamped outside 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 being damaged by the extrusion of the segmented frame 4.

[0041] In one embodiment, the single-sided foam tape 3 is a PVC foam tape.
