Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to an encapsulation frame and a photovoltaic module. Background Technology

[0002] To improve the power output of photovoltaic (PV) modules, manufacturers have begun exploring ways to hide the busbars at both ends of the module behind the solar cells, thereby increasing the screen-to-body ratio and thus boosting power. However, placing the busbars on the back of the solar cells results in a thicker PV module at the busbar location after lamination, meaning the shorter side of the module is thicker than the longer side. If traditional frame technology is used for framing in this case, defects such as component bursts and adhesive overflow are highly likely, and the reliability of the shorter frame will also be affected. Utility Model Content

[0003] Therefore, it is necessary to provide a packaging frame that can improve the stability, yield and reliability of the manufacturing process of full-screen photovoltaic module products and reduce the risk of component explosion.

[0004] One embodiment of this application provides an encapsulation border.

[0005] An encapsulation frame includes a plurality of frame components for encapsulating the longer and shorter edges of a laminate. Each frame component includes a frame body, an abutment, and a limiting member. A portion of the outer surface of the frame body forms a bearing surface. One end of the abutment is connected to the bearing surface, and the other end is connected to the limiting member. The limiting member, the abutment, and the bearing surface together form a mounting groove for mounting the edge of the laminate. The bearing surface supports the back panel of the laminate, the abutment abuts against the end face of the laminate, and the limiting member presses against the front panel of the laminate.

[0006] In the frame component used to encapsulate the longer edge of the laminate, the two ends of the bearing surface in the mounting groove are respectively recessed to form receiving grooves for accommodating the busbar. The depth H1 of the mounting groove of the frame component used to encapsulate the shorter edge of the laminate is the sum of the depth H2 of the mounting groove of the frame component used to encapsulate the longer edge of the laminate and the depth H3 of the receiving groove.

[0007] In some embodiments, the limiting member is parallel to the bearing surface.

[0008] In some embodiments, the top surface of the limiting member is a convex curved surface.

[0009] In some embodiments, the width W1 of the limiting member is 2mm to 7mm.

[0010] In some embodiments, the width W1 of the limiting member is smaller than the width W2 of the bearing surface.

[0011] In some embodiments, the limiting member has a recessed overflow groove on its inner surface facing the bearing surface, the overflow groove being used to accommodate a portion of the overflowed adhesive.

[0012] In some embodiments, the frame body, the abutment, and the limiting member are connected as a single unit.

[0013] In some embodiments, the height H4 of the border member used to encapsulate the longer edge of the laminate is equal to the height H5 of the border member used to encapsulate the shorter edge of the laminate.

[0014] In some embodiments, the frame body of the frame component for encapsulating the longer edge of the laminate has a first corner code cavity for corner code embedding and connection, and the frame body of the frame component for encapsulating the shorter edge of the laminate has a second corner code cavity for corner code embedding and connection; the height H6 of the first corner code cavity is greater than the height H7 of the second corner code cavity by equal amounts.

[0015] In some embodiments, the length of the receiving groove along the extension direction of the frame member is 20mm to 25mm.

[0016] In some embodiments, the bottom surface of the receiving groove transitions to the bearing surface with a slope.

[0017] In some embodiments, the bearing surface has a plurality of adhesive grooves.

[0018] In some embodiments, the inner wall of the adhesive container gradually narrows from the bottom surface of the container to the opening.

[0019] In some embodiments, the frame body includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall. The first sidewall, the second sidewall, the third sidewall, and the fourth sidewall are connected sequentially to make the frame body a hollow quadrangular prism structure. The outer surface of the first sidewall forms the bearing surface, and the abutment is connected to the first sidewall.

[0020] In some embodiments, the frame body is connected to a number of reinforcing ribs.

[0021] In some embodiments, the frame body is a metal frame made of metal or alloy material, or a composite material frame made of composite material.

[0022] One embodiment of this application provides a photovoltaic module.

[0023] A photovoltaic module includes a laminate and an encapsulation frame as described in any of the above embodiments. The laminate includes a back panel, a back adhesive film, a cell, a front adhesive film, and a front panel stacked sequentially. The laminate is encapsulated by the encapsulation frame. A portion of the back panel of the laminate is located on the bearing surface. An end face of the laminate can abut against the abutment member. A portion of the front panel of the laminate abuts against the limiting member.

[0024] The aforementioned encapsulation frame, by setting multiple frame components for encapsulating the longer and shorter edges of the laminate, has a basically the same structure for each frame component. The difference lies in that, in the frame component for encapsulating the longer edge of the laminate, the two ends of the bearing surface within the mounting groove are recessed to form receiving grooves for accommodating the busbar. These receiving grooves can accommodate the busbar hidden on the short side of the back of the laminate. With the busbar accommodated within the receiving groove, there is no need to increase the depth H2 of the mounting groove, and the mounting groove normally engages the main body of the laminate. The depth H1 of the mounting groove of the frame component with the shorter edge is the sum of the depth H2 of the mounting groove of the frame component with the shorter edge for encapsulating the laminate and the depth H3 of the receiving groove. With this setting, by setting the overall depth H1 of the mounting groove for the shorter edge of the slot to be increased, and the depth H2 of the mounting groove for the longer edge of the slot to be widened locally at both ends, the stability, yield and reliability of the frame assembly process of the full-screen photovoltaic module product can be improved without increasing the cost of the encapsulation frame material, and the risk of component explosion caused by size mismatch during assembly can be reduced.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] One embodiment of this application provides an encapsulation frame to solve at least one of the following technical problems in the conventional process of assembling a hidden busbar module: (1) the short side of the photovoltaic module is very prone to jamming and bursting the frame; (2) the reduced gap space between the frame groove and the photovoltaic module causes more sealant to be squeezed out inside the frame, affecting the appearance and reliability of the entire photovoltaic module product. The encapsulation frame will be described below with reference to the accompanying drawings.

[0045] The encapsulation border provided in one embodiment of this application is exemplary; please refer to [link to relevant documentation]. Figure 1 , 2 As shown, Figure 1 This is a schematic diagram of a frame component for encapsulating the shorter edge of the laminate in an embodiment of this application. Figure 2 This is a schematic diagram of a frame component used for encapsulating the longer edge of the laminate in an embodiment of this application. The encapsulation frame of this application can be used for the encapsulation of photovoltaic modules, especially busbar-hidden photovoltaic modules.

[0046] To more clearly illustrate the structure of the package frame, the following description of the package frame will be provided in conjunction with the accompanying drawings.

[0047] For example, one type of encapsulation border can be found here. Figure 1 , Figure 2As shown, the device includes multiple frame components 100a and 100b for encapsulating the longer and shorter edges of the laminate 200, respectively. Each frame component 100a and 100b includes a frame body 110, an abutment 120, and a limiting member 130. A portion of the outer surface of the frame body 110 forms a bearing surface 101. One end of the abutment 120 is connected to the bearing surface 101, and the other end is connected to the limiting member 130. The limiting member 130, the abutment 120, and the bearing surface 101 form mounting grooves 140a and 140b for mounting the edges of the laminate 200. Specifically, mounting groove 140a mounts the longer edge of the laminate 200, and mounting groove 140b mounts the shorter edge of the laminate 200. The bearing surface 101 supports the back panel 201 of the laminate 200, and the abutment 120 abuts against the end face of the laminate 200. The limiting member 130 is used to press against the front panel 205 of the laminate 200.

[0048] Please refer to Figure 2 As shown, in the frame member 100a for encapsulating the longer edge of the laminate 200, the two ends of the bearing surface 101 in the mounting groove 140a are recessed to form receiving grooves 141 for accommodating the busbar. The depth H1 of the mounting groove 140b of the frame member 100b for encapsulating the shorter edge of the laminate 200 is the sum of the depth H2 of the mounting groove 140a of the frame member 100a for encapsulating the longer edge of the laminate 200 and the depth H3 of the receiving groove 141. During installation, since the mounting groove 140b is used to accommodate the shorter edge of the laminate 200, the depth H1 of the mounting groove 140b needs to be slightly increased, for example, from 6.1 mm in conventional technology to 6.7 mm, to accommodate the thickness of the busbar. The overall height of the frame member 100b needs to be increased, thus without increasing material costs.

[0049] The aforementioned encapsulation frame can improve the stability, yield, and reliability of the manufacturing process of full-screen photovoltaic module products, and reduce the risk of component explosions.

[0050] In some embodiments, the limiting member 130 is parallel to the bearing surface 101.

[0051] In some embodiments, the top surface of the limiting member 130 is a convex curved surface. The design of the top surface of the limiting member 130 being a convex curved surface allows for quick cleaning of dust and other debris during outdoor use of the photovoltaic module. Smaller dust particles and rainwater falling onto the top surface of the limiting member 130 will slide off along the edge of the frame under the influence of the curved surface and gravity, reducing dust and rain accumulation.

[0052] In some embodiments, the width W1 of the limiting member 130 is 2mm to 7mm.

[0053] In some implementations, see Figure 1 As shown, the width W1 of the limiting member 130 is smaller than the width W2 of the bearing surface 101. The setting that the width W1 of the limiting member 130 is smaller than the width W2 of the bearing surface 101 facilitates the assembly of the laminate 200, and makes it easier for operators or machinery to clamp the edge of the laminate 200 into the mounting grooves 140a and 140b, reducing the risk of explosion.

[0054] In some embodiments, the limiting member 130 has a recessed overflow groove 131 on its inner surface facing the bearing surface 101. The overflow groove 131 is used to accommodate a portion of the overflowing adhesive. The overflow groove 131 can hold a portion of the adhesive, and after the adhesive in the overflow groove 131 cures, it can connect with a portion of the laminate 200, improving the connection strength between the limiting member 130 and the laminate 200. Optionally, the structure, shape, and size of the overflow groove 131 can be configured as needed.

[0055] In some embodiments, the frame body 110, the abutment 120, and the limiting member 130 are connected in an integral structure.

[0056] In some embodiments, the height H4 of the border member 100a for encapsulating the longer edge of the laminate 200 and the height H5 of the border member 100b for encapsulating the shorter edge of the laminate 200 are equal.

[0057] In some embodiments, the frame body 110 of the frame member 100a for encapsulating the longer edge of the laminate 200 has a first corner code cavity 103a for corner code embedding and connection, and the frame body 110 of the frame member 100b for encapsulating the shorter edge of the laminate 200 has a second corner code cavity 103b for corner code embedding and connection; the height H6 of the first corner code cavity 103a is greater than the height H7 of the second corner code cavity 103b by the same amount.

[0058] In some embodiments, the length of the receiving groove 141 along the extension direction of the frame member 100a is 20mm to 25mm.

[0059] In some implementations, see Figure 3 As shown, the bottom surface of the receiving trough 141 transitions to the bearing surface 101 with a slope.

[0060] In some embodiments, the bearing surface 101 has a plurality of adhesive grooves. The adhesive grooves are not shown in the drawings. The adhesive grooves can hold a portion of the adhesive, thereby improving its adhesive strength and enhancing the connection between the back panel 201 and the bearing surface 101.

[0061] In some embodiments, the inner wall of the adhesive container gradually narrows from the bottom to the opening. This design allows the bonded part to form a structure that is larger on the inside and smaller on the outside after the adhesive has cured, making it difficult for the bonded part to detach from the adhesive container and improving the bonding strength between the back panel 201 and the bearing surface 101.

[0062] In some embodiments, the frame body 110 includes a first sidewall 111, a second sidewall 112, a third sidewall 113, and a fourth sidewall 114. The first sidewall 111, the second sidewall 112, the third sidewall 113, and the fourth sidewall 114 are connected sequentially to make the frame body 110 have a hollow quadrangular prism structure. The outer surface of the first sidewall 111 forms a bearing surface 101, and the abutment member 120 is connected to the first sidewall 111.

[0063] In some embodiments, a plurality of reinforcing ribs are connected to the frame body 110. The reinforcing ribs are not shown. The reinforcing ribs can improve the strength of the frame body 110. Optionally, the reinforcing ribs can be structures such as protrusions or plates. Optionally, the reinforcing ribs 115 can extend from one sidewall to the other sidewalls.

[0064] In some embodiments, the frame body 110 is a metal frame made of metal or alloy material, or a composite material frame made of composite material.

[0065] One embodiment of this application provides a photovoltaic module.

[0066] See Figure 4 , Figure 5 As shown, Figure 4 This is a schematic diagram of a portion of a photovoltaic module according to an embodiment of this application. Figure 5 for Figure 4 The diagram shown is an enlarged view of a portion of the structure of a photovoltaic module. A photovoltaic module 10 includes a laminate 200 and an encapsulation frame as described in any of the above embodiments. (See attached diagram.) Figure 6 As shown, Figure 6 This is a schematic diagram of a laminate structure according to an embodiment of the present application. The laminate 200 includes a back panel 201, a back adhesive film 202, a battery 203, a front adhesive film 204, and a front panel 205 stacked sequentially. The laminate 200 is encapsulated by an encapsulation frame. Part of the back panel 201 of the laminate 200 is located on the bearing surface 101. The end face of the laminate 200 can abut against the abutment member 120. Part of the front panel 205 of the laminate 200 abuts against the limiting member 130.

[0067] There can be multiple border components 100a and 100b. When there are multiple border components 100a and 100b, the end faces of adjacent border components 100a and 100b can be joined together with a 45° bevel cut to achieve a 90° angle splicing between adjacent border components 100a and 100b. During processing, the end faces of border components 100a and 100b can be cut to make the end faces of border components 100a and 100b have a 45° bevel.

[0068] The lengths of the border components 100a and 100b can be set according to the length or width of the laminate 200, and no specific limitation is made here.

[0069] In some embodiments, during encapsulation, adjacent frame components 100a and 100b can be connected by corner brackets, which can be inserted into the first corner bracket cavity 103a and the second corner bracket cavity 103b of adjacent frame components 100a and 100b.

[0070] In some embodiments, the adhesive used for encapsulation can be the glue used in the photovoltaic field, and no specific limitation is made here.

[0071] In some embodiments, the front panel 205 and the back panel 201 described above can be independently selected from photovoltaic glass panels.

[0072] The aforementioned encapsulation frame comprises multiple frame components 100a and 100b, respectively used for the longer and shorter edges of the encapsulated laminate 200. The structures of each frame component 100a and 100b are basically the same, except that in the frame component 100a used for the longer edge of the encapsulated laminate 200, the two ends of the bearing surface 101 within the mounting groove 140a are recessed to form receiving grooves 141 for accommodating the busbar. These receiving grooves 141 can accommodate the busbar hidden on the shorter side of the back of the laminate 200. With the busbar accommodated within the receiving groove 141, there is no need to increase the depth H2 of the mounting groove 140a, allowing the laminate 200 to be properly secured within the mounting groove 140a. The main body; the depth H1 of the mounting groove 140b of the frame component 100b for the shorter edge of the encapsulation laminate 200 is the sum of the depth H2 of the mounting groove 140a of the frame component 100b for the shorter edge of the encapsulation laminate 200 and the depth H3 of the receiving groove 141. With this setting, by setting the depth H1 of the mounting groove 140b for the shorter edge of the slot to be increased as a whole, and the depth H2 of the mounting groove 140a for the longer edge of the slot to be locally widened at both ends, the stability, yield and reliability of the frame assembly process of the full-screen photovoltaic module product can be improved without increasing the cost of the encapsulation frame material, and the risk of explosion caused by size mismatch during assembly can be reduced.

[0073] In summary, compared with traditional technologies, the packaging frame of this utility model has the following beneficial effects:

[0074] (1) Airborne reliability: The laminating component 200 is bound by the limiting component 130 and the receiving groove 131 inside the limiting component 130 to accommodate the adhesive, which can maximize the airborne load strength.

[0075] (2) Dust prevention: The top surface of the limiting part 130 is curved, and a small amount of dust can be more easily washed away by rainwater, thus achieving the purpose of preventing dust accumulation.

[0076] (3) Reduce costs: By setting the depth H1 of the mounting groove 140b for the shorter edge of the card slot to be increased as a whole, and the depth H2 of the mounting groove 140a for the longer edge of the card slot to be locally widened at both ends, the stability, yield and reliability of the full-screen photovoltaic module product manufacturing process can be improved without increasing the cost of the encapsulation frame material, without increasing the amount of material used.

[0077] (4) Aesthetically pleasing appearance: The packaging frame of this application is preferably made of composite material, which can be made of a variety of colors such as black and dark blue, forming the same color as the battery, and has a better visual effect.

[0078] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.
