Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic double-glass component lamination devices, and specifically discloses a double-glass photovoltaic component lamination internal tooling and an installation structure thereof. Background Art

[0002] Compared with ordinary photovoltaic modules, double-glass photovoltaic modules have higher power generation, and the double-sided photovoltaic glass makes them more weather-resistant, and their service life is improved under conditions such as ultraviolet rays, dust, and salt spray. Because double-glass modules are different from conventional single-glass modules, double-glass modules have a rigid structure with glass on both sides, while single-glass module panels are flexible structures; and during the lamination process, the modules are subjected to downward thermal stress on all sides, and when cooled after lamination, there is cold stress in the opposite direction. Therefore, when the rigid structure of the double-glass module is subjected to cold stress, the glass tends to warp outward, and air absorption bubbles are easily generated. Therefore, when laminating double-glass modules, lamination frames or lamination corner guards need to be placed to prevent uneven force on the modules.

[0003] However, currently the laminating frame or the corner protector is manually taken and placed, which affects the production efficiency. In addition, the laminating frame is very likely to be displaced during the transmission process. If the laminating frame is displaced onto the component, serious abnormalities such as the laminating frame crushing the component may occur. Summary of the invention

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a double-glass photovoltaic module lamination internal tooling and its installation structure which can facilitate the switching of various double-glass photovoltaic module formats during lamination and improve the product yield.

[0005] According to the technical solution provided by the utility model, the double-glass photovoltaic module lamination internal tooling includes a lamination strip and a fixing plate; at least two fixing plates are fixed on the same side of the lamination strip, the bottom surface of the fixing plate is flush with the bottom surface of the lamination strip, the thickness of the fixing plate is less than the thickness of the lamination strip, and a plurality of groups of adjustment fixing holes are opened on each fixing plate, and the plurality of groups of adjustment fixing holes are distributed at intervals along the width direction of the lamination strip.

[0006] Preferably, the laminated strip has a length of 2600-3000 mm, a width of 25-35 mm, and a thickness of 6-7 mm.

[0007] Preferably, the fixing plate has a length of 38-42 mm, a width of 28-32 mm, and a thickness of 1-2 mm.

[0008] An installation structure of an internal tooling for laminating a double-glass photovoltaic module further includes a lower heating plate of a laminator. A mounting hole for the lower heating plate of the laminator is provided on the lower heating plate of the laminator. Screws are installed in the adjustment and fixing holes of the fixing piece and the mounting hole for the lower heating plate of the laminator to fix one inner and one outer laminating strip on the upper surface of the lower heating plate of the laminator. The length direction of the laminating strip is the same as the length direction of the lower heating plate of the laminator. The end of the laminating strip retracts a certain distance from the corresponding end of the lower heating plate of the laminator. The two laminating strips are arranged in parallel. The upper surface of the lower heating plate of the laminator between the two laminating strips is the placement area for the double-glass photovoltaic module, and the fixing piece is located outside the placement area for the double-glass photovoltaic module.

[0009] The utility model simplifies the lamination process of the double-glass photovoltaic module, improves the product yield of the double-glass photovoltaic module, and reduces the defective rate such as component explosion after lamination caused by the unfixed placement position of the lamination frame or corner guard in the prior art.

[0010] The utility model fixes the internal tooling for laminating the double-glass photovoltaic module on the lower heating plate of the laminator, and can disassemble or adjust the distance between the two laminating strips at any time, which is convenient for the lamination requirements of different versions of the double-glass photovoltaic module.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the utility model clearer, the technical solutions of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are some but not all of the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0016] An internal tooling for laminating a double-glass photovoltaic module, as Figures 1-3As shown in the figure, it includes a lamination strip 1 and a fixing piece 2; at least two fixing pieces 2 are fixed on the same side of the lamination strip 1, the bottom surface of the fixing piece 2 is flush with the bottom surface of the lamination strip 1, the thickness of the fixing piece 2 is less than the thickness of the lamination strip 1, and a number of groups of adjusting and fixing holes 2.1 are provided on each fixing piece 2, and the number of groups of adjusting and fixing holes 2.1 are spaced along the width direction of the lamination strip 1.

[0017] The length of the lamination strip 1 is 2600 - 3000 mm, the width is 25 - 35 mm, and the thickness is 6 - 7 mm.

[0018] The length of the fixing piece 2 is 38 - 42 mm, the width is 28 - 32 mm, and the thickness is 1 - 2 mm.

[0019] An installation structure of an internal tooling for laminating a double - glass photovoltaic module is as Figure 4 shown, and it further includes a lower heating plate 3 of the laminator. A lower - heating - plate installation hole of the laminator is provided on the lower heating plate 3 of the laminator. Screws are installed in the adjusting and fixing holes 2.1 of the fixing piece 2 and the lower - heating - plate installation hole of the laminator to fix one inner and one outer lamination strip 1 on the upper surface of the lower heating plate 3 of the laminator. The length direction of the lamination strip 1 is the same as the length direction of the lower heating plate 3 of the laminator. No lamination strip 1 is installed on the wide side of the lower heating plate 3 of the laminator. The end of the lamination strip 1 retracts a certain distance from the corresponding end of the lower heating plate 3 of the laminator. The two lamination strips 1 are arranged in parallel. The upper surface of the lower heating plate 3 between the two lamination strips 1 is the placement area for the double - glass photovoltaic module, and the fixing piece 2 is located outside the placement area for the double - glass photovoltaic module.

[0020] In the present utility model, the length direction of the lamination strip 1 is the same as the length direction of the lower heating plate 3 of the laminator. No lamination strip 1 is installed on the wide side of the lower heating plate 3 of the laminator. When placing the double - glass photovoltaic module 4, the wide side of the double - glass photovoltaic module 4 faces the corresponding lamination strip 1, and the distance between the wide side of the double - glass photovoltaic module 4 and the nearest lamination strip 1 is controlled within 5 - 10 mm. During lamination, it can prevent the double - glass photovoltaic module 4 from fluctuating up and down and displacing during the internal transfer process of the laminator, resulting in serious abnormalities such as the explosion of the pressing frame. By aligning the lower - heating - plate installation hole of the laminator with different adjusting and fixing holes 2.1 and tightening with fastening bolts, the distance between the two lamination strips 1 can be changed to adapt to the lamination requirements of different versions of the double - glass photovoltaic module 4.

[0021] Since the lamination strip 1 is fixed on the upper surface of the lower heating plate 3 of the laminator through the fixing piece 2, the phenomenon of displacement of the lamination strip 1 will not occur during the transmission process, avoiding serious abnormalities such as the pressing frame pressing and exploding the double - glass photovoltaic module 4 caused by the displacement of the lamination frame onto the double - glass photovoltaic module 4 in the prior art, and improving the product yield of the double - glass photovoltaic module 4.

[0022] Finally, it should be noted that the above specific implementation manners are only used to illustrate the technical solutions of the present utility model rather than to limit them. Although the present utility model has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and all of them should be covered within the scope of the claims of the present utility model.
