[0002] Solar cells are devices that can directly convert light energy into electrical energy and have broad application prospects. A single solar cell produces a low voltage and is fragile and not resistant to aging. Therefore, multiple solar cells are usually electrically connected and tightly packaged to form a laminate to obtain better performance.

[0003] Photovoltaic modules are usually composed of solar cells, adhesive films and packaging boards. Among them, solar cells, adhesive films and packaging boards are formed into photovoltaic modules that can be used in practice after stacking, layout, welding, glass bonding and lamination processes. During the lamination process, it is usually necessary to place the parts to be laminated in a lamination frame to reduce the force on the corners of the parts to be laminated during the lamination process, thereby reducing the problem of broken cells. Among them, the material of the lamination frame is usually metal such as aluminum alloy or stainless steel, resulting in high consumables costs in the lamination process. Utility Model Content

They are only for the convenience and simplification of the description of the content of the utility model and to help readers understand the description in conjunction with the drawings. They do not limit or imply a specific orientation that the device or element referred to must have, and therefore should not be understood as a limitation on the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by technicians in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the implementation of the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items. "Multiple" herein includes a combination of two or more than two items.

[0028] The present invention provides a lamination bearing assembly, which includes a base high-temperature cloth and a limiting high-temperature cloth; the base high-temperature cloth has a lamination surface for bearing the parts to be laminated, the limiting high-temperature cloth is connected to the base high-temperature cloth, the limiting high-temperature cloth is protruded on the lamination surface, and the limiting high-temperature cloth surrounds a lamination limiting groove located on the lamination surface, and the lamination limiting groove is used to accommodate the parts to be laminated.

[0029] The lamination bearing assembly disclosed in the present invention is provided with a base high temperature cloth and a limiting high temperature cloth. The limiting high temperature cloth is connected to the base high temperature cloth, and the limiting high temperature cloth forms a lamination limiting groove located on the lamination surface of the base high temperature cloth, and the lamination limiting groove is used to accommodate the parts to be laminated. In actual use, the parts to be laminated are placed in the lamination limiting groove. The lamination bearing assembly can play a role in heat preservation, ensuring the uniformity and flatness of the heating of the parts to be laminated during the lamination process, and the limiting high temperature cloth therein can also reduce the stress on the corners and edges of the assembly, reducing the problem of broken pieces during the lamination process. Moreover, compared with the lamination frame made of metal material used in traditional technology, the material cost of the lamination bearing assembly is significantly lower. Therefore, the lamination bearing assembly can replace the lamination frame used in the traditional lamination process, effectively reducing the consumables cost of the lamination process.

[0030] The lamination process involves heating and pressurizing the parts to be laminated so that the adhesive film therein is cured. High-temperature cloth is a cloth that can withstand high temperatures and is often placed between the parts to be laminated and the heating plate in the lamination process. The present disclosure cleverly improves the high-temperature cloth commonly used in traditional technology and provides a lamination bearing assembly including a base high-temperature cloth and a limiting high-temperature cloth to reduce the problem of broken pieces during the lamination process. The lamination bearing assembly is used to assist in the lamination of the parts to be laminated, without the need to introduce additional equipment in the traditional process, and can also save the lamination frame used in the traditional process. In addition, the lamination frame used in the traditional lamination process usually requires a special operator to configure the lamination frame, while the lamination bearing assembly can be used directly in conjunction with the lamination equipment, thereby saving the manpower required for the lamination process.

[0031] Figure 1 FIG. 1 is a top view of a laminated load-bearing assembly 100 in an embodiment of the present disclosure. Figure 1As shown, the lamination bearing assembly 100 comprises a base high temperature cloth 110 and a limiting high temperature cloth 120. The base high temperature cloth 110 has a lamination surface 111 for bearing the component 200 to be laminated. Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure of the laminated load-bearing assembly 100 along AA'. Figure 1 and Figure 2 As shown, the limiting high temperature cloth 120 is connected to the base high temperature cloth 110, the limiting high temperature cloth 120 is protrudingly arranged on the lamination surface 111, and the limiting high temperature cloth 120 surrounds a lamination limiting groove 130 located on the lamination surface 111, and the lamination limiting groove 130 is used to accommodate the laminated component 200.

[0032] The base high temperature cloth 110 and the limiting high temperature cloth 120 are both high temperature cloth. High temperature cloth refers to a cloth material that can maintain its properties and performance in a temperature environment above 200°C. Since high temperature cloth has a strong tolerance to high temperature environments and has a certain buffering effect, it is often placed between the laminated part 200 and the heating plate during the lamination process.

[0033] Reference Figure 1 As shown, in this embodiment, the limiting high temperature cloth 120 can be in a ring shape with four sides closed, and the inner side of the ring of the limiting high temperature cloth 120 can enclose the lamination limiting groove 130, the inner side wall of the limiting high temperature cloth 120 is the groove side wall of the lamination limiting groove 130, and the groove bottom wall of the lamination limiting groove 130 is the lamination surface 111 of the base high temperature cloth 110. It can be understood that in this embodiment, when in use, the laminated component 200 can be placed in the lamination limiting groove 130 in a aligned manner.

[0034] As some examples of this embodiment, the limiting high temperature cloth 120 is a solid strip of high temperature cloth. It can be understood that the head end and the tail end of the strip of high temperature cloth are connected to form a laminated limiting groove 130 on the laminated surface 111. Among them, the solid strip of high temperature cloth means that the limiting high temperature cloth 120 is entirely made of high temperature cloth material. The solid strip of high temperature cloth is relatively soft and can play a better buffering role for the laminate 200. Not only that, in actual use, the laminated bearing assembly 100 needs to undergo rotation and bending during the cyclic movement. Compared with the structural design with hard materials as internal support, the solid strip of high temperature cloth is more suitable for the above-mentioned rotation and bending actions, avoiding deformation or displacement of the laminated bearing assembly 100, and ensuring the accurate alignment of the laminated bearing assembly 100 during use.

[0035] Reference Figure 1 and Figure 2As shown, as some examples of this embodiment, the position-limiting high-temperature cloth 120 is integrally connected to the base high-temperature cloth 110. The position-limiting high-temperature cloth 120 is integrally connected to the base high-temperature cloth 110, so that the connection between the position-limiting high-temperature cloth 120 and the base high-temperature cloth 110 is tighter, and the misalignment and deformation of the laminated position-limiting groove 130 caused by the deformation of the position-limiting high-temperature cloth 120 during use is reduced, and the durability of the laminated bearing assembly 100 is further improved.

[0036] Reference Figure 1 and Figure 2 As shown, as some examples of this embodiment, the laminated bearing assembly 100 can be composed of a base high temperature cloth 110 and a limiting high temperature cloth 120 .

[0037] As some examples of this embodiment, the material of the position-limiting high temperature cloth 120 is the same as that of the base high temperature cloth 110. In this example, both the position-limiting high temperature cloth 120 and the base high temperature cloth 110 can be polytetrafluoroethylene cloth. Setting the position-limiting high temperature cloth 120 and the base high temperature cloth 110 to be the same cloth material is conducive to simplifying the manufacturing process of the laminated bearing assembly 100 on the one hand, and can also improve the bonding strength between the position-limiting high temperature cloth 120 and the base high temperature cloth 110 on the other hand.

[0038] As some examples of this embodiment, along the direction away from the lamination surface 111, the height of the limiting high temperature cloth 120 is 5mm-10mm. Figure 2 As shown, the position-limiting high-temperature cloth 120 has a bottom end in contact with the laminating surface 111 of the base high-temperature cloth 110 and a top end away from the laminating surface 111. The height of the position-limiting high-temperature cloth 120 is the distance h between the top and the bottom. The laminating position-limiting groove 130 formed by the position-limiting high-temperature cloth 120 with a height of 5 mm to 10 mm is more suitable for the actual version of the laminated component 200, and can more effectively protect the corners of the laminated component 200 while ensuring the normal lamination process.

[0039] Further, in this example, the height h of the position-limiting high temperature cloth 120 can be 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm or 10mm. Alternatively, the height h of the position-limiting high temperature cloth 120 can also be in the range between any two of the above heights.

[0040] As some examples of this embodiment, the distance between the outer wall of the position-limiting high-temperature cloth 120 and the inner wall of the position-limiting high-temperature cloth 120 is 30 mm to 100 mm. Figure 2As shown, the position-limiting high-temperature cloth 120 has an inner side wall close to the lamination position-limiting groove 130 and an outer side wall away from the lamination position-limiting groove 130, and the distance d between the outer side wall and the inner side wall can be regarded as the width of the position-limiting high-temperature cloth 120. The position-limiting high-temperature cloth 120 with a width of 30 mm to 100 mm can ensure that the shape of the enclosed lamination position-limiting groove 130 is more stable, and has a stronger buffering capacity during the lamination process, and has a better protection effect on the corners of the laminated component 200.

[0041] Further, in this example, the distance d between the outer wall and the inner wall of the position-limiting high-temperature cloth 120 can be 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm. Alternatively, the distance d between the outer wall and the inner wall of the position-limiting high-temperature cloth 120 can also be in the range between any two of the above distances.

[0042] It can be understood that the size of the lamination limiting groove 130 can be set accordingly according to the size of the laminated component 200. For example, the laminated component 200 should be able to be placed in the lamination limiting groove 130, and when the laminated component 200 is located in the lamination limiting groove 130, the distance between the edge of the laminated component 200 and the groove side wall of the lamination limiting groove 130 can be ≤10mm. Among them, the edge of the laminated component 200 can be spaced apart from the groove side wall of the lamination limiting groove 130, or at least part of the edge of the laminated component 200 can abut against the groove side wall of the lamination limiting groove 130.

[0043] As some examples of this embodiment, the cross section of the lamination limiting groove 130 parallel to the lamination surface 111 is rectangular.

[0044] In some examples, the length of the cross section of the lamination limiting groove 130 is 2280 mm to 2300 mm. For example, the length of the cross section of the lamination limiting groove 130 is 2280 mm, 2282 mm, 2285 mm, 2288 mm, 2290 mm, 2292 mm, 2295 mm, 2298 mm, 2300 mm, or the length of the cross section of the lamination limiting groove 130 can also be in the range between any two of the above lengths.

[0045] In some examples, the width of the cross section of the lamination limiting groove 130 is 1140 mm to 1150 mm. For example, the width of the cross section of the lamination limiting groove 130 is 1140 mm, 1141 mm, 1142 mm, 1143 mm, 1144 mm, 1145 mm, 1146 mm, 1147 mm, 1148 mm, 1150 mm, or the width of the cross section of the lamination limiting groove 130 can also be in the range between any two of the above widths.

[0046] Reference Figure 1As shown, as some examples of this embodiment, the lamination bearing assembly 100 may include a plurality of limiting high temperature cloths 120 of the same shape, the plurality of limiting high temperature cloths 120 are arranged in parallel on the base high temperature cloth 110, and the plurality of lamination limiting grooves 130 surrounded by the plurality of limiting high temperature cloths 120 are arranged in parallel and spaced on the lamination surface 111. In the actual lamination process, a plurality of to-be-laminated parts 200 to be laminated enter the lamination equipment in sequence for lamination processing. A plurality of lamination limiting grooves 130 are arranged on a lamination bearing assembly 100, and each lamination limiting groove 130 can be used to accommodate the to-be-laminated parts 200 to be laminated. It is only necessary to move the lamination bearing assembly 100 step by step, and a lamination bearing assembly 100 can carry a plurality of to-be-laminated parts 200 and laminate them in sequence, which can improve the lamination efficiency.

[0047] It can be understood that, in this example, two adjacent limiting high-temperature cloths 120 can be in contact or spaced apart, which can enable the lamination limiting grooves 130 to be spaced apart.

[0048] Reference Figure 1 As shown, as some examples of this embodiment, a plurality of position-limiting high-temperature cloths 120 are arranged at intervals, and among the plurality of position-limiting high-temperature cloths 120 , the interval between two adjacent position-limiting high-temperature cloths 120 is a constant value.

[0049] Further, in this example, the spacing between two adjacent position-limiting high-temperature cloths 120 may be 10 cm to 50 cm. For example, the spacing between two adjacent position-limiting high-temperature cloths 120 may be 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, 35 cm, 40 cm, 45 cm, 50 cm, or the spacing between two adjacent position-limiting high-temperature cloths 120 may be between any two of the above spacings.

[0050] Figure 3 for Figure 1 Schematic diagram of the structure of the laminated bearing assembly 100 and the laminated component 200 when used in conjunction with each other. Figure 3 As shown, the laminated component 200 to be laminated is aligned with the lamination limiting groove 130 in the lamination bearing assembly 100, and the lamination bearing assembly 100 is pressed down so that the laminated component 200 is accommodated in the lamination limiting groove 130. After that, the lamination bearing assembly 100 and the laminated component 200 can be placed on a heating plate as a whole for heating and pressure treatment, and the lamination process can be completed. In the lamination process, the limiting high temperature cloth 120 can block the edge of the laminated component 200, reduce the force on the corners of the component during the lamination process, and thus the problem of component fragmentation can be reduced.

[0051] In yet another aspect, the present disclosure further provides a photovoltaic module lamination device, the photovoltaic module lamination device comprising the lamination support assembly 100 as in the above embodiment.

[0052] As some examples of this embodiment, the photovoltaic component lamination equipment may include a high-temperature cloth moving mechanism, and the lamination bearing assembly 100 may be arranged on the high-temperature cloth moving mechanism, and the high-temperature cloth moving mechanism is used to drive the lamination bearing assembly 100 to move.

[0053] As some examples of this embodiment, the photovoltaic module lamination equipment may further include a lamination bearing mechanism, which may be used to bear the photovoltaic module to be laminated, and the photovoltaic module may include a solar cell string, an adhesive film, and a packaging plate, and the adhesive film is arranged between the solar cell string and the packaging plate. In this example, the bearing mechanism may be a heating plate. Furthermore, the moving path of the high temperature cloth moving mechanism may pass through the bearing mechanism.

[0054] As some examples of this embodiment, the photovoltaic module lamination equipment may further include a lamination pressure mechanism, and the lamination pressure mechanism is used to apply pressure toward the lamination support mechanism to perform a lamination process.

[0055] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above 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.

[0056] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they 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.
