[0002] BIPV (Building Integrated Photovoltaic) technology integrates photovoltaic modules into buildings, so that they can not only generate electricity but also be used as building materials. The photovoltaic modules used in BIPV technology need to be laminated at high temperature through laminating equipment to form a composite layer. During the lamination process, laminating tooling is required to protect the photovoltaic modules so that the photovoltaic modules to be laminated are evenly compressed in the laminating equipment. However, the laminating tooling in the prior art has the problem of poor applicability to photovoltaic modules of different specifications. Since the size and thickness of the photovoltaic modules in BIPV products need to be customized according to different construction projects, the size of the laminating tooling also needs to be customized separately, which increases the cost and cycle of module production, which also leads to a higher production cost of BIPV products.

[0039] The lamination tooling of the photovoltaic module according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0041] Reference Figure 1 , Figure 2 The lamination tooling 100 of the photovoltaic module provided in the embodiment of the present application includes a frame 10, and the frame 10 includes a plurality of splicing segments 20 and a plurality of connecting components 30. The frame 10 is formed by splicing a plurality of splicing segments 20 in sequence end to end, and each two adjacent splicing segments 20 are connected by a connecting component 30.
[0042] Each of the split sections 20 includes at least two split layers 21 . The at least two split layers 21 can be stacked on top of each other as a multi-layer structure or used as a single layer.
[0043] The frame 10 is composed of multiple splicing segments 20 which are spliced end to end in sequence. Every two adjacent splicing segments 20 are connected by a connecting component 30, and the splicing layers 21 in each splicing segment 20 can also be used in a single layer or in multiple layers. With this arrangement, the number of splicing segments 20 can be flexibly adjusted according to the length, width, and thickness of the object to be laminated. The number of splicing layers 21 in the splicing segment 20 can be applicable to objects to be laminated of various specifications, thereby reducing the production cost of BIPV products.
[0044] For multiple splicing segments 20 connected end to end in sequence, if the two ends of each splicing segment 20 are defined as the head end and the tail end, then, in each adjacent two splicing segments 20, the head end of one splicing segment 20 is connected to the tail end of the other splicing segment 20 through a connecting component 30. The splicing segments 20 are connected in sequence in the above manner to form a closed frame 10, and the shape of the frame can be square or other shapes.
[0045] In the embodiment of the present application, when at least two splicing layers 21 of the same splicing section 20 are stacked into multiple layers, at least a portion of the two adjacent splicing layers 21 are provided with a first plug-in structure 211 and a second plug-in structure 212 on the surfaces facing each other that can be plugged in and matched with each other. Of course, the above-mentioned plug-in structures may be provided on both opposite surfaces of each group of adjacent splicing layers 21, or only a portion of the adjacent splicing layers 21 may be provided with the above-mentioned plug-in structures.
[0046] This arrangement can assist in positioning adjacent splicing layers 21 so that adjacent splicing layers 21 will not be misaligned. The first plug-in structure 211 and the second plug-in structure 212 can be arranged in the entire length direction of the splicing section 20, or only in a part of the length direction of the splicing section 20.
[0047] Further, one of the first plug-in structure 211 and the second plug-in structure 212 is a groove, and the other is a protrusion.
[0048] The cross-sectional profile of the groove and the protrusion is configured as a semicircle, for example Figure 2 Alternatively, the cross-sectional profile of the groove and the protrusion is configured as a trapezoid, for example Figure 3 shown.
[0049] The groove may be along the width direction of the spliced section 20 ( Figure 2 The strip grooves are arranged in a direction perpendicular to the straight surface, and the protrusions are strip-shaped grooves that match the groove shape. In addition, the cross-sectional profiles of the grooves and protrusions are not limited to semicircular and trapezoidal, and can also be configured as toothed, square, etc.
[0050] Furthermore, the frame 10 further includes a fixing tape (not shown), which wraps and fixes each splicing layer 21 of the same splicing section 20 .
[0051] By providing the fixing tape, the connection strength of each splicing layer 21 is made higher. The fixing tape can be a high temperature tape so as not to be affected during the lamination process.
[0052] In the present application, refer to Figure 4-Figure 7 The connecting assembly 30 may include a connecting arm 31. One of the two adjacent splicing sections 20 is connected to one end of the connecting arm 31 through a fastener 32, and the other is connected to the other end of the connecting arm 31 through a fastener 32. In this way, the connection of adjacent splicing sections 20 can be easily achieved.
[0053] Furthermore, there are two connecting arms 31, which are arranged opposite to each other around the circumference of the splicing section 20. In this way, the two connecting arms 31 make the connection strength of adjacent splicing sections 20 higher, and the two connecting arms 31 are arranged opposite to each other, so that the circumferential force of the splicing section 20 can be more uniform.
[0054] Specifically, when the frame 10 is a square frame, the two connecting arms 31 can be respectively located on the inner side surface and the outer side surface of the frame 10. In addition, the two connecting arms 31 can be linear ( Figure 5 ) or curved ( Figure 7 ) two ways.
[0055] Reference Figure 6 and Figure 7 As a possible implementation manner, the connecting arm 31 between the two ends of the connecting arm 31 is arched in a direction away from the connecting arm 31 .
[0056] Such an arrangement allows adjacent splicing sections 20 to have a certain degree of freedom of movement in the length direction of the splicing sections 20. When there is a slight error in the size of the object to be laminated, the two adjacent splicing sections 20 can adjust their relative positions through the arched connecting arm 31 to adapt to the error in size, thereby making the lamination tooling more versatile.
[0057] In the present application, refer to Figure 8 , Fig. 9 and Fig.10 The connection assembly 30 includes a hinge 33. Two adjacent splicing sections 20 are hingedly connected via the hinge 33.
[0058] With such arrangement, when not in use, the adjacent spliced sections 20 can be folded up, occupying less space and being convenient for storage.
[0059] Furthermore, the extension direction of the hinge 33 , that is, the intersection axis of the two splicing sections 20 is along the thickness direction of the frame 10 , and adjacent splicing sections 20 are staggered with each other in the thickness direction of the frame 10 .
[0060] So set up, refer to Figure 8 and Fig. 9 As shown, after the adjacent spliced sections 20 are folded together, one of them can overlap with the other, so that the entire frame has a smaller volume and occupies less space when not in use.
[0061] In addition, when adjacent splicing sections 20 are staggered in the thickness direction of the frame 10, for example, adjacent splicing sections 20 can be arranged closely in the thickness direction of the frame 10, so that after the adjacent splicing sections 20 are folded with each other, the two splicing sections 20 can be attached together, so that the volume of the frame 10 is smaller when not in use.
[0062] Further, continue to refer to Figure 1 Among the spliced sections 20, at least part of the spliced sections 20 is constructed in a straight line shape, and at least part of the spliced sections 20 is constructed in a right angle shape.
[0063] In this way, frames 10 of different shapes can be assembled. For example, by arranging four right-angled assembly segments 20 and connecting the straight assembly segments 20 to the two side ends of the right-angled assembly segments 20, a rectangular frame 10 can be assembled. Of course, the present application is not limited thereto, and the number of the right-angled assembly segments 20 and the straight assembly segments 20 can also be other numbers to form frames 10 of other different shapes.
[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0065] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
