Technical Field
[0001] This application relates to the field of photovoltaic power generation, and more particularly to a laminated frame. Background Technology
[0002] With the development of technology, the utilization of energy is receiving increasing attention. The role of photovoltaic power generation technology in daily life is becoming increasingly prominent. Photovoltaic power generation technology can convert light energy into electrical energy, making full use of nature's energy resources.
[0003] Currently, with the major trend of cost reduction and efficiency improvement in photovoltaic module manufacturing, the use of lamination frames in the lamination process of double-glass modules has become inevitable. Generally speaking, one glass thickness corresponds to one lamination frame thickness. However, due to varying demands on photovoltaic module products, a single type of photovoltaic module often requires glass of different thicknesses. This necessitates lamination frames of varying thicknesses, increasing the manufacturing cost of photovoltaic modules. Utility Model Content
[0004] To solve one of the above-mentioned technical problems, this utility model provides a laminate frame.
[0005] This utility model provides a laminate frame, which includes a first outer frame, a second outer frame, and at least one pad frame. The pad frame is detachably disposed between the first outer frame and the second outer frame via a connector.
[0006] Preferably, the first outer frame has a plurality of first insertion holes perpendicular to the plane of the first outer frame, the second outer frame has a plurality of second insertion holes perpendicular to the plane of the second outer frame, and the pad frame has a plurality of third insertion holes perpendicular to the plane of the pad frame. The plurality of first insertion holes, the plurality of second insertion holes, and the plurality of third insertion holes respectively form a plurality of insertion hole groups, and the connector passes through the insertion hole groups.
[0007] Preferably, the outer diameter of the connector gradually decreases from one end to the other, and at least one of the first socket and the second socket forms an interference fit with the connector.
[0008] Preferably, the socket group is provided with an internal thread, the outer periphery of the connector is provided with an external thread, and the connector is threadedly connected to the socket group.
[0009] Preferably, the length of the connector is less than or equal to the length of the socket group.
[0010] Preferably, the plurality of first sockets, the plurality of second sockets, and the plurality of third sockets are evenly distributed on the frames of the first outer frame, the second outer frame, and the pad frame.

[0014] Preferably, there are multiple pad frames, and the multiple pad frames are stacked between the first outer frame and the second outer frame from top to bottom.
[0015] The beneficial effects of this invention are as follows: The laminate frame proposed in this invention has a spacer frame between the two outer frames, and the spacer frame is detachably connected to the two outer frames. Depending on the thickness of the glass, the spacer frame corresponding to the glass thickness can be replaced between the two outer frames. The thickness of the laminate frame can also be adjusted by increasing or decreasing the number of spacers, thus achieving adjustable laminate frame thickness. Furthermore, only the number of spacers is required, eliminating the need to purchase large quantities of laminate frames and reducing the manufacturing cost of photovoltaic modules.

[0029] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0030] Example 1
[0031] like Figure 1 As shown, this embodiment proposes a lamination frame for fixing the laminated components during the photovoltaic module lamination process. Specifically, the lamination frame includes a first outer frame 1, a second outer frame 3, and a pad frame 2, wherein the pad frame 2 is located between the first outer frame 1 and the second outer frame 3.
[0032] In this embodiment, the laminated frame comprises a three-layer structure: an upper first outer frame 1, a middle pad frame 2, and a lower second outer frame 3. The first outer frame 1, the pad frame 2, and the second outer frame 3 have the same length and width to ensure the overall neatness of the laminated frame's edges. In this embodiment, there are actually multiple pad frames 2, but in actual use, only one needs to be placed between the first outer frame 1 and the second outer frame 3. The thicknesses of the multiple pad frames 2 vary; for example, the pad frames 2 can be designed with specifications such as 1.6mm, 1.8mm, and 2.0mm. In actual use, if the glass thickness of the photovoltaic module is 1.6mm, then a 1.6mm thick pad frame 2 can be placed between the first outer frame 1 and the second outer frame 3, such as... Figure 2 As shown. If a photovoltaic module with a glass thickness of 2.0mm needs to be manufactured next, then the original 1.6mm thick spacer frame 2 can be removed and replaced with a 2.0mm thick spacer frame 2, as shown. Figure 3As shown, the height of the laminate frame can be adjusted using only one set of outer frames, and the cost of multiple pad frames 2 is far less than the purchase cost of multiple laminate frames of different specifications.
[0033] It should be noted that the size differences shown in the illustration are only to more clearly distinguish the effects presented by pads 2 of different thicknesses, and do not represent the actual size.
[0034] In some optional embodiments, the pad frame 2 is detachably connected to the first outer frame 1 and the second outer frame 3, specifically through a connector 5. Insertion holes are provided on the first outer frame 1, the pad frame 2, and the second outer frame 3, and the connector 5 achieves the detachable connection between the pad frame 2 and the first outer frame 1 and the second outer frame 3 by inserting into these holes.
[0035] Specifically, multiple first insertion holes 1-1 are provided on the frame of the first outer frame 1, and the length direction of each first insertion hole 1-1 is perpendicular to the plane of the first outer frame 1. Multiple second insertion holes 3-1 are provided on the frame of the second outer frame 3, and the length direction of each second insertion hole 3-1 is perpendicular to the plane of the second outer frame 3. Multiple third insertion holes 2-1 are provided on the frame of the pad frame 2, and the length direction of each third insertion hole 2-1 is perpendicular to the plane of the pad frame 2. The first insertion holes 1-1, second insertion holes 3-1, and third insertion holes 2-1 are in a one-to-one correspondence, that is, after the first outer frame 1, pad frame 2, and second outer frame 3 are placed in place, a corresponding first insertion hole 1-1, a second insertion hole 3-1, and a third insertion hole 2-1 can form a complete through insertion hole. For ease of description, the through insertion hole formed by the first insertion hole 1-1, the second insertion hole 3-1, and the third insertion hole 2-1 is called insertion hole group 4, such as... Figure 4 As shown. The connector 5 is inserted into the socket group 4, and the connector 5 and the socket group 4 are interference fit, so that the connection between the first outer frame 1, the pad frame 2 and the second outer frame 3 can be realized.
[0036] In some alternative embodiments, if the connector 5 is interference-fitted with the first socket 1-1, the second socket 3-1, and the third socket 2-1 of the socket group 4, then a high positional accuracy is required for the first outer frame 1, the pad frame 2, and the second outer frame 3. Therefore, in actual use, as long as at least one of the first socket 1-1 of the first outer frame 1 and the second socket 3-1 of the second outer frame 3 can be interference-fitted with the connector 5, the positional limitation of the first outer frame 1, the pad frame 2, and the second outer frame 3 can be achieved.
[0037] In some alternative embodiments, a threaded connection may also be used between the connector and the socket assembly.
[0038] Specifically, internal threads can be machined on the inner side of the socket assembly, and correspondingly, external threads can be machined on the outer periphery of the connector. During the insertion of the connector into the socket assembly, the connection between the connector and the socket assembly is achieved through the threaded connection of the internal and external threads.
[0039] In some optional embodiments, the length of the connector 5 is less than or equal to the length of the socket group 4, preferably the length of the connector 5 is equal to the length of the socket group 4. This ensures the connection between the first outer frame 1, the pad frame 2, and the second outer frame 3, while also ensuring the flatness of the surfaces of the first outer frame 1 and the second outer frame 3. When a threaded connection is selected between the connector and the socket group, a countersunk threaded hole design can be used.
[0040] In some alternative embodiments, the connector 5 is implemented with a structure that is thinner at the top and thicker at the bottom.
[0041] Specifically, to facilitate smooth insertion of the connector 5, the inner diameters of the first socket 1-1 of the first outer frame 1, the second socket 3-1 of the second outer frame 3, and the third socket 2-1 of the pad frame 2 are identical. To ensure a secure connection between the first outer frame 1, the pad frame 2, and the second outer frame 3, the connector 5 has an overall shape that is thinner at the top and thicker at the bottom. That is, the outer diameter of the connector 5 gradually decreases from one end to the other, and the minimum outer diameter of the connector 5 is the same as the inner diameters of the first socket 1-1, the second socket 3-1, and the third socket 2-1. Figure 5 As shown. Meanwhile, the connector 5 can be made of a material with a certain degree of resilience. In this way, the connector 5 can not only be inserted into the first socket 1-1, the second socket 3-1, and the third socket 2-1, but also, through its own resilience, tightly adhere to the inner walls of the first socket 1-1, the second socket 3-1, and the third socket 2-1, thereby increasing the friction between the connector 5 and the first socket 1-1, the second socket 3-1, and the third socket 2-1, and thus ensuring the stability of the connection between the first outer frame 1, the pad frame 2, and the second outer frame 3.
[0042] In some alternative embodiments, the first socket 1-1, the second socket 3-1, and the third socket 2-1 can be designed as circular or square holes. Circular holes distribute force more evenly, while square holes can increase the contact area of the inner wall of the socket within a limited frame width. The specific shape of the socket can be determined according to the actual situation. Correspondingly, the shape of the connector 5 can be adjusted and adapted according to the shapes of the first socket 1-1, the second socket 3-1, and the third socket 2-1. Specifically, it can be a trapezoidal cylindrical structure or a trapezoidal prism structure, etc.
[0043] In some optional embodiments, a plurality of first sockets 1-1, a plurality of second sockets 3-1 and a plurality of third sockets 2-1 are evenly distributed on the frames of the first outer frame 1, the second outer frame 3 and the pad frame 2, so as to ensure that the first outer frame 1, the second outer frame 3 and the pad frame 2 are subjected to more uniform force.
[0044] In some alternative embodiments, at least one set of holes 4 is provided on each of the four sides of the laminate frame to further ensure the uniformity of the stress on the laminate frame.
[0045] In some alternative embodiments, the first outer frame 1 and the second outer frame 3 have the same thickness to ensure the consistency of the upper and lower structures of the laminated frame.
[0046] Example 2
[0047] like Figure 6 As shown, this embodiment proposes a lamination frame for fixing the laminated components during the photovoltaic module lamination process. Specifically, the lamination frame includes a first outer frame 1, a second outer frame 3, and multiple spacer frames 2, wherein the multiple spacer frames 2 are located between the first outer frame 1 and the second outer frame 3.
[0048] In this embodiment, the laminated frame includes a multi-layer structure, wherein the upper layer is a first outer frame 1, the middle layer consists of multiple stacked pad frames 2, and the lower layer is a second outer frame 3. The first outer frame 1, the pad frames 2, and the second outer frame 3 all have the same length and width to ensure the overall neatness of the laminated frame's edges. In this embodiment, there are multiple pad frames 2; in actual use, the number of pad frames 2 can be adjusted according to the thickness of the photovoltaic module glass. For example, the thickness of multiple pad frames 2 can be designed to be 0.5mm. If the glass thickness is 1.5mm, three stacked pad frames 2 can be placed between the first outer frame 1 and the second outer frame 3. Figure 7 As shown. If the glass thickness is 2.0mm, four stacked pad frames 2 can be placed between the first outer frame 1 and the second outer frame 3, as shown. Figure 8 As shown. Furthermore, the thicknesses of multiple pad frames 2 can be designed differently. For example, one pad frame 2 can be 0.5mm thick, and another can be 1.2mm thick. Then, stacking two pad frames 2 together will create a thickness of 1.7mm. Figure 9 As shown, height adjustment can also be achieved.
[0049] In some optional embodiments, the pad frame 2 is detachably connected to the first outer frame 1 and the second outer frame 3, specifically through a connector 5. Insertion holes are provided on the first outer frame 1, the pad frame 2, and the second outer frame 3, and the connector 5 achieves the detachable connection between the pad frame 2 and the first outer frame 1 and the second outer frame 3 by inserting into these holes.
[0050] Specifically, multiple first sockets 1-1 are provided on the frame of the first outer frame 1, and the length direction of each first socket 1-1 is perpendicular to the plane of the first outer frame 1. Multiple second sockets 3-1 are provided on the frame of the second outer frame 3, and the length direction of each second socket 3-1 is perpendicular to the plane of the second outer frame 3. Multiple third sockets 2-1 are provided on the frame of the pad frame 2, and the length direction of each third socket 2-1 is perpendicular to the plane of the pad frame 2. The first sockets 1-1, second sockets 3-1, and third sockets 2-1 are in a one-to-one correspondence, that is, after the first outer frame 1, the pad frame 2, and the second outer frame 3 are placed in place, a corresponding first socket 1-1, a second socket 3-1, and a third socket 2-1 can form a complete through socket. For ease of description, the through socket formed by the first socket 1-1, the second socket 3-1, and the third socket 2-1 is referred to as socket group 4. The connector 5 is inserted into the socket group 4, and the connector 5 and the socket group 4 are interference fit, so that the connection between the first outer frame 1, the pad frame 2 and the second outer frame 3 can be realized.
[0051] In some alternative embodiments, the length of the connector 5 is greater than or equal to the length of the socket group 4, and preferably the length of the connector 5 is equal to the length of the socket group 4. This ensures the connection between the first outer frame 1, the pad frame 2, and the second outer frame 3, while also ensuring the flatness of the surfaces of the first outer frame 1 and the second outer frame 3.
[0052] In some alternative embodiments, the connector 5 is implemented with a structure that is thinner at the top and thicker at the bottom.
[0053] Specifically, to facilitate smooth insertion of the connector 5, the inner diameters of the first socket 1-1 of the first outer frame 1, the second socket 3-1 of the second outer frame 3, and the third socket 2-1 of the pad frame 2 are identical. To ensure a secure connection between the first outer frame 1, the pad frame 2, and the second outer frame 3, the connector 5 has an overall shape that is thinner at the top and thicker at the bottom. That is, the outer diameter of the connector 5 gradually decreases from one end to the other, and the minimum outer diameter of the connector 5 is the same as the inner diameter of the first socket 1-1, the second socket 3-1, and the third socket 2-1. Furthermore, the connector 5 can be made of a material with a certain degree of resilience. In this way, the connector 5 can be inserted into the first socket 1-1, the second socket 3-1 and the third socket 2-1, and can also be tightly attached to the inner wall of the first socket 1-1, the second socket 3-1 and the third socket 2-1 through its own elasticity, so as to increase the friction between the connector 5 and the first socket 1-1, the second socket 3-1 and the third socket 2-1, thereby ensuring the stability of the connection between the first outer frame 1, the pad frame 2 and the second outer frame 3.
[0054] In some alternative embodiments, the first socket 1-1, the second socket 3-1, and the third socket 2-1 can be designed as circular or square holes. Circular holes distribute force more evenly, while square holes can increase the contact area of the inner wall of the socket within a limited frame width. The specific shape of the socket can be determined according to the actual situation. Correspondingly, the shape of the connector 5 can be adjusted and adapted according to the shapes of the first socket 1-1, the second socket 3-1, and the third socket 2-1. Specifically, it can be a trapezoidal cylindrical structure or a trapezoidal prism structure, etc.
[0055] In some optional embodiments, a plurality of first sockets 1-1, a plurality of second sockets 3-1 and a plurality of third sockets 2-1 are evenly distributed on the frames of the first outer frame 1, the second outer frame 3 and the pad frame 2, so as to ensure that the first outer frame 1, the second outer frame 3 and the pad frame 2 are subjected to more uniform force.
[0056] In some alternative embodiments, at least one set of holes 4 is provided on each of the four sides of the laminate frame to further ensure the uniformity of the stress on the laminate frame.
[0057] In some alternative embodiments, the first outer frame 1 and the second outer frame 3 have the same thickness to ensure the consistency of the upper and lower structures of the laminated frame.
[0058] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
