In addition, the character " / " in the present application generally represents that the front and rear associated objects have an "or" relationship.

[0043] In the related art, at present, when the photovoltaic module has been operated for several years, for example, about 10 years, the encapsulation adhesive film of the photovoltaic module will fail, causing delamination of the edge part of the laminated part of the photovoltaic module. The delamination will cause the invasion of external moisture, thereby causing a series of problems such as PID effect (phenomenon of power attenuation of solar cells under a certain external voltage for a long time), insulation failure, etc., accordingly causing insulation alarm of the photovoltaic module, and affecting the power generation of the photovoltaic module. The delamination problem refers to the appearance phenomenon that the internal adhesive film of the photovoltaic module and the glass, the adhesive film and the adhesive film, or the adhesive film and the cell appear gap, which will cause the creepage path to decrease, causing insulation failure or power generation efficiency to decrease.

[0044] In the related art, the delamination problem of the photovoltaic module is usually solved by the following method, for example, the photovoltaic module is disassembled into a plurality of components, the plurality of components are packaged and transported back to the production workshop, and the high-pressure kettle is used for pressurizing and heating. After the repair is completed, the repaired photovoltaic module components are packaged and transported to the original installation position.

[0045] In short, in the above-mentioned solution for the photovoltaic module, the photovoltaic module is disassembled, the module is transported back, the module is packaged, and the high-pressure kettle is pressurized and heated. The labor cost and transportation cost are very huge. According to the current selling price of 800 yuan per photovoltaic module, the labor cost is 200 yuan per piece, the transportation cost is 200 yuan per piece, the rework is 100 yuan per piece, and the delivery and installation are 400 yuan per piece. In total, the repair of one photovoltaic module requires 900 yuan, while the selling price is only 800 yuan. This does not include spare parts, packaging materials, and loading and unloading costs, which are actually more.

[0046] However, the inventors realize that in operation, the photovoltaic module that has delamination problem is disassembled and transported back to the production workshop for repair, and then the repaired photovoltaic module is transported to the original installation position, thereby increasing the transportation and repair cost of the photovoltaic module and reducing the repair efficiency of the photovoltaic module.

[0047] Figure 1 Fig. 1 is an exploded structural schematic view of a repair device and a photovoltaic module according to some embodiments of the present application, Figure 2 Fig. 2 is an assembled structural schematic view of a repair device and a photovoltaic module according to some embodiments of the present application, Figure 3 Fig. 3 is a structural schematic view of a press tool 2 according to some embodiments of the present application.

[0048] One or more embodiments of the present application disclose a repair device suitable for a photovoltaic module. Referring to Figure 1 and Figure 2 , the repair device suitable for the photovoltaic module comprises a press tool 2 and a heating structure 1, the press tool 2 comprises a cover 212, a base 213 and a connecting assembly 22, the cover 212 and the base 213 are connected through the connecting assembly 22, a first mounting groove 211 is formed between the cover 212 and the base 213, the heating structure 1 is embedded in the first mounting groove 211, the first mounting groove 211 is used for embedding a frame 31 of the photovoltaic module 3, and the heating structure 1 is used for being attached to the frame 31.

[0049] Specifically, the first mounting groove 211 is along Figure 1 the Z-axis direction of the coordinate system, and the size of the first mounting groove 211 is the depth of the first mounting groove 211, the heating structure 1 and the frame 31 of the photovoltaic module 3 are along Figure 1 the Z-axis direction of the coordinate system, and the size of the heating structure 1 and the frame 31 is the thickness of the heating structure 1 and the frame 31, wherein the sum of the thickness of the heating structure 1 and the frame 31 matches the depth of the first mounting groove 211, so that the frame 31 of the photovoltaic module 3 and the heating structure 1 can be embedded in the first mounting groove 211.

[0050] The first mounting groove 211 can adopt the following three structural modes, for example, the cover 212 is provided with a first groove, the base 213 is provided with a second groove, and when the cover 212 is connected and assembled with the base 213 through the connecting assembly 22, the first groove and the second groove are combined to form the first mounting groove 211; or the cover 212 is provided with a first groove, and when the cover 212 is connected and assembled with the base 213 through the connecting assembly 22, the first groove of the cover 212 and the base 213 form the first mounting groove 211; or the base 213 is provided with a second groove, and the cover 212 and the second groove of the base 213 form the first mounting groove 211.

[0051] The heating structure 1 can adopt a heating blanket structure, for example, the heating blanket comprises an insulating and heat-conducting pad having an internal cavity and a heating device which can be installed in the cavity of the insulating and heat-conducting pad (similar to the structure of an electric blanket), and the heating device is electrically connected with an external power source through a power line to not only play an insulating protection role on the heating device but also conduct the heat generated by the heating device to the laminated piece of the photovoltaic module 3 through the frame 31.

[0052] The delamination position of the photovoltaic module 3 is basically at the side edges and corners of the laminated piece, so the pressure tool 2 is basically in a U-shaped structure when projected on a horizontal plane, and the heat generated by the heating structure 1 can be conducted to the laminated piece through the frame to heat the edges and corners of the laminated piece to solve the delamination problem of the photovoltaic module.

[0053] The insulating and heat-conducting pad can be made of a material such as silicone rubber which has both insulation and heat conduction functions. The heating device can be a heating wire, so that the entire heating structure 1 has a certain softness and can be smoothly embedded in the first installation groove 211.

[0054] For example, the gland 212 can be fixedly connected with the base 213 through the connecting assembly 22 or can be detachably connected.

[0055] For example, the gland 212 and the base 213 can be detachably connected. Before the heating structure 1 and the frame 31 are installed in the interior of the first installation groove 211, the connecting assembly 22 can be adjusted to make the gland 212 and the base 213 moveable and separated, so as to help the heating structure 1 to be smoothly embedded between the gland 212 and the base 213, and correspondingly improve the disassembly and assembly operation of the heating structure 1 and the frame 31 with the pressure tool 2; and the pressure tool 2 adopts the detachable gland 212 and the base 213 which are connected through the connecting assembly 22, so compared with the integral pressure tool, the close contact degree of the heating structure 1 with the photovoltaic module 3 can be adjusted by adjusting the tightness of the connecting assembly 22, and the flexibility is stronger and the operation is more flexible, so even if the photovoltaic module 3 is deformed during the repair process, the deformed part can be flexibly repaired alone, and correspondingly the service life is prolonged.

[0056] When the photovoltaic module 3 has been in operation for a long time and delamination occurs at the edge of the laminate of the photovoltaic module 3, the frame 31 of the photovoltaic module 3 does not need to be disassembled, and the delamination problem of the photovoltaic module 3 can be solved on site. For example, the cover 212 and the base 213 are assembled by the connecting assembly 22, and a first mounting groove 211 is formed between the assembled cover 212 and the base 213. The heating structure 1 is embedded in the first mounting groove 211 of the pressing tool 2, and then the frame 31 of the photovoltaic module 3 is inserted into the first mounting groove 211, and the heating structure 1 is attached to the frame 31. Then, the heating structure 1 is powered on, and the heat generated by the heating structure 1 under the power-on condition is conducted to the edge of the laminate of the photovoltaic module 3 through the frame 31, so that the delamination part of the laminate is heated to quickly recover, thereby achieving quick repair work for the delamination problem of the photovoltaic module 3 at the installation position of the photovoltaic module 3. Since the photovoltaic module 3 with the delamination problem does not need to be disassembled, packaged and sent back to the production workshop for maintenance, the transportation and maintenance costs are effectively reduced, and the maintenance efficiency is improved.

[0057] Figure 4 Partial structure of the pressing tool 2 according to some embodiments of the present application.

[0058] In some embodiments, in combination with Figure 3 and Figure 4 As shown, the connecting assembly 22 includes a plurality of first fasteners 221, and the plurality of first fasteners 221 are arranged at intervals along the extension direction of the pressing tool 2. The first fasteners 221 are arranged through one of the cover 212 and the base 213, and are connected to the other one of the cover 212 and the base 213.

[0059] In at least one embodiment, the projection of the entire pressing tool 2 on the horizontal plane can be substantially in a U-shaped structure, so as to match the shape of the frame 31 of the photovoltaic module 3.

[0060] The plurality of first fasteners 221 are arranged at intervals along the extension direction of the pressing tool 2, so as to increase the number of connection points of the cover 212 and the base 213, and to uniformly distribute the connection and fastening force of the cover 212 and the base 213, so that the attachment surface of the heating structure 1 and the frame 31 is relatively flat. Therefore, the heating structure 1 can more uniformly conduct heat to the frame 31, and improve the repair effect on the delamination problem of the photovoltaic module 3. Since the projection of the pressing tool 2 on the horizontal plane can be substantially in a U-shaped structure, the extension direction of the pressing tool 2 is not a straight line, but a bending tool with a U-shaped structure.

[0061] The cover 212 and the base 213 can be arranged in a vertical direction, for example, the cover 212 is above the base 213; the first fastener 221 is used to fasten the cover 212 and the base 213, if the first fastener 221 is a first bolt structure, first threaded holes and second threaded holes are respectively arranged at corresponding positions of the cover 212 and the base 213, so that the threaded holes of the cover 212 and the base 213 are penetrated by the first bolt structure, so as to realize the disassembly and assembly of the cover 212 and the base 213.

[0062] The first fastener 221 is penetrated in one of the cover 212 and the base 213, and connected with the other one of the cover 212 and the base 213, that is, if the head end of the first bolt structure is below, the first bolt structure penetrates the second threaded hole of the base 213 from below, and is connected with the first threaded hole of the cover 212, so as to realize the connection of the cover 212 and the base 213; if the head end of the first bolt structure is above, the first bolt structure penetrates the first threaded hole of the cover 212 from above, and is connected with the second threaded hole of the base 213.

[0063] For example, if the first fastener 221 includes a first bolt and a first nut, first through holes and second through holes can be respectively arranged on the cover 212 and the base 213, the first bolt penetrates the first through hole of the cover 212 and the second through hole of the base 213 and is connected with the first nut, so as to realize the connection and fixation of the cover 212 and the base 213 through the first fastener 221.

[0064] In some embodiments, in combination with Figure 3 and Figure 4 As shown in the drawings, the connecting assembly 22 includes a plurality of second fasteners 222, the second fasteners 222 are arranged alternately with the first fasteners 221, the diameter of the first fastener 221 is greater than the diameter of the second fastener 222, the second fastener 222 is penetrated in one of the cover 212 and the base 213, and is connected with the other one of the cover 212 and the base 213.

[0065] In at least one embodiment, the second fastener 222 is arranged alternately with the first fastener 221, that is, at least one second fastener 222 is arranged between two adjacent first fasteners 221.

[0066] The structure of the second fastener 222 can be the same as or different from that of the first fastener 221, as long as different bolt fastening modes for connecting the cover 212 and the base 213 are applicable to the technical solution, which is not limited here.

[0067] The diameter of the first fastener 221 is greater than the diameter of the second fastener 222, in other words, the diameter of the second fastener 222 is smaller than the first fastener 221, so that the second fastener 222 can assist the connection of the grommet 212 and the base 213. Since the second fastener 222 is arranged alternately with the first fastener 221, and a plurality of second fasteners 222 are also arranged at intervals along the extension direction of the pressing tool 2, during the tightening of the first fastener 221, the plurality of second fasteners 222 arranged at intervals along the extension direction of the pressing tool 2 can ensure that the connection force of the entire grommet 212 and the base 213 is evenly distributed, reducing the possibility and amplitude of the bulging deformation of the heating structure 1 and the frame 31 in the area between two adjacent first fasteners 221.

[0068] Figure 5 Fig. 2 is a second exploded schematic view of a partial structure of the pressing tool 2 according to some embodiments of the present application.

[0069] In some embodiments, in combination with Figure 5 As shown, the connecting assembly 22 includes an elastic structure 223, the elastic structure 223 includes an elastic body 2231, the base 213 is provided with a second mounting groove 2131, one end of the elastic body 2231 is inserted into the second mounting groove 2131, and the other end of the elastic structure 223 abuts against the grommet 212.

[0070] In at least one embodiment, the elastic body 2231 can be a column structure made of flexible material, or can be a compression spring structure; the elastic body 2231 can produce axial compression deformation when subjected to extrusion, and restore to its original shape to elongate when the extrusion force is lost.

[0071] The diameter of the second mounting groove 2131 is greater than the diameter of the elastic body 2231, so that the elastic body 2231 can be smoothly inserted or embedded in the second mounting groove 2131.

[0072] When the elastic body 2231 is embedded in the second mounting groove 2131, the distance between the gland 212 and the base 213 becomes smaller and smaller with the rotation of the first fastener 221 and the second fastener 222 in the process of connecting the base 213 by the first fastener 221 and the second fastener 222, and the volume of the first mounting groove 211 between the gland 212 and the base 213 also becomes smaller. At this time, the elastic body 2231 embedded in one end of the second mounting groove 2131 is extruded by the gland 212, so that the elastic body 2231 is deformed. In this process, the second mounting groove 2131 can limit the elastic body 2231 to prevent the elastic body 2231 from being bent. After the photovoltaic module 3 is repaired and cooled, the first fastener 221 and the second fastener 222 are loosened. At this time, the elastic body 2231 is elongated due to its own restoring force after losing the fastening force of the first fastener 221 and the second fastener 222, and can push the gland 212 upward to assist the manual separation of the gland 212 and the base 213, thereby improving the convenience of disassembling the gland 212 and the base 213.

[0073] In some embodiments, in combination with Figure 5 As shown, the elastic structure 223 further includes a rod-shaped structure 2232, the gland 212 is provided with a mounting hole 2121, the elastic body 2231 is sleeved on part of the rod-shaped structure 2232, and both ends of the rod-shaped structure 2232 extend into the mounting hole 2121 and the second mounting groove 2131, respectively. The diameter of the elastic body 2231 is greater than the diameter of the mounting hole 2121.

[0074] In at least one embodiment, if the elastic body 2231 is a column structure made of flexible material, a through hole structure can be formed in the column structure to facilitate the rod-shaped structure 2232 to pass through. If the elastic body 2231 is a compression spring, the rod-shaped structure 2232 can directly pass through the compression spring.

[0075] The inner diameter of the mounting hole 2121 is greater than or equal to the rod-shaped structure 2232, so that the rod-shaped structure 2232 can smoothly pass into the mounting hole 2121 of the gland 212. After the gland 212 and the base 213 are fastened, the rod-shaped structure 2232 can pass out of the mounting hole 2121 of the gland 212 upward, or can not protrude from the top surface of the gland 212, so that the rod-shaped structure 2232 passing through the mounting hole 2121 of the gland 212 will not hinder the connection and fastening of the gland 212 and the base 213.

[0076] The rod-shaped structure 2232 can be a column structure (such as a circular column, a polygonal column, etc.), or a bolt structure, which is not specifically limited here.

[0077] The diameter of the elastomer 2231 is larger than the diameter of the mounting hole 2121. During the connection and fastening process between the cover 212 and the base 213, the elastomer 2231 can be effectively prevented from entering the mounting hole 2121, so as to prevent the elastomer 2231 from failing to provide an upward lifting effect on the cover 212 when the cover 212 and the base 213 are separated in the future.

[0078] When the cap 212 and the base 213 are not tightened, a portion of the elastic body 2231 is embedded in the second mounting groove 2131, and another portion of the elastic body 2231 protrudes from the second mounting groove 2131 of the base 213. A portion of the rod-shaped structure 2232 passes through the elastic body 2231 and is located in the second mounting groove 2131, while another portion of the rod-shaped structure 2232 protrudes from the second mounting groove 2131. During the connection and tightening process between the cap 212 and the base 213, the cap 212 compresses the portion of the elastic body 2231 protruding from the second mounting groove 2131, causing it to undergo compressive deformation. After the pressure fixture 2 has repaired the frame 31 of the photovoltaic module, during the disassembly of the cap 212 and the base 213, the elastic body 2231 extends after losing the pressure of the cap 212, pushing the cap 212 upwards, which can assist in the disassembly of the cap 212 and the base 213.

[0079] Since one end of the rod-shaped structure 2232 penetrating the elastic body 2231, for example, the bottom end, is inserted into the second mounting groove 2131 of the base 213, and the other end of the rod-shaped structure 2232, for example, the top end, is inserted into the mounting hole 2121 of the cover 212, it can guide the compression deformation and reset deformation of the elastic body 2231 in sequence during the connection and fastening process of the cover 212 and the base 213, as well as during the separation process of the cover 212 and the base 213, to prevent the elastic body 2231 from bending, thereby avoiding obstruction to the connection and fastening of the cover 212 and the base 213, and ensuring the upward pushing action of the cover 212 during the separation process of the cover 212 and the base 213.

[0080] Figure 6 This is a partial structural schematic diagram of the cap 212 according to some embodiments of this application. Figure 7 for Figure 2 A magnified structural diagram of part A in the middle.

[0081] In some embodiments, combined with Figure 6 and Figure 7 As shown, the pressure cover 212 includes a connecting part 2122 and an arc-shaped part 2123. The connecting part 2122 is connected to the base 213 through the connecting component 22. The connecting part 2122 is used to fit against the frame 31. The arc-shaped part 2123 is disposed at the end of the connecting part 2122 and is used to fit against the glass 32 of the photovoltaic module 3.

[0082] In at least one embodiment, in combination with Figure 2 and Figure 7 As shown in the figure, the frame 31 of the photovoltaic module 3 has a top surface in the positive direction of the Z-axis in the coordinate system, which is also the front surface of the frame 31, and the front surface of the frame 31 has an arc shape; the frame 31 of the photovoltaic module 3 has a side surface in the positive and negative directions of the X-axis in the coordinate system; and the frame 31 of the photovoltaic module 3 has a bottom surface in the negative direction of the Z-axis in the coordinate system. Figure 2 Figure 2 Figure 2

[0083] The connecting portion 2122 can have an L-shaped structure, so that the connecting portion 2122 has two mutually perpendicular sides, which are respectively attached to the top surface (front surface) and side surface of the frame 31 of the photovoltaic module 3, and when the frame 31 is embedded in the first mounting groove 211, the upper surface of the base 213 can be attached to the bottom surface of the frame 31.

[0084] The connecting portion 2122 and the arc-shaped portion 2123 of the gland 212 can be processed in the following manner: for example, a part of a straight plate structure is first bent at a right angle to form an L-shaped connecting portion 2122, and then other parts of the straight plate structure can be bent in an arc shape to form an arc-shaped portion 2123, so that the connecting portion 2122 and the bent portion can form an integrated gland 212, thereby ensuring that the gland 212 has a certain mechanical strength.

[0085] Therefore, the arc-shaped region of the arc-shaped portion 2123 of the gland 212 can be adapted to the front surface of the frame 31, and the bottom of the arc-shaped portion 2123 can be attached to the glass 32 of the photovoltaic module 3, so that the connecting portion 2122 of the gland 212 can wrap the top surface and side surface of the frame 31, and the upper surface of the base 213 can be attached to the bottom surface of the frame 31, and the arc-shaped portion 2123 can be attached to the glass 32 protruding from the frame 31, so as to fully surround the frame 31, thereby improving the repair effect on the delamination of the inner laminated member of the frame 31 of the photovoltaic module 3.

[0086] Figure 8 For Figure 3 the enlarged structural schematic view of part B.

[0087] In some embodiments, in combination with Figure 8 As shown in the figure, the pressing tool 2 further comprises a first buffer block 214, which is arranged on the surface of the arc-shaped portion 2123 facing the glass 32.

[0088] And / or, the pressing tool 2 further comprises a second buffer block 215, which is arranged on the surface of the base 213 facing the frame 31. ​​​

[0089] In at least one embodiment, the first buffer block 214 and the second buffer block 215 can be made of a flexible deformable material, such as a rubber block, a silicone block, or the like. The first buffer block 214 can be fixed to the surface of the arc-shaped portion 2123 facing the glass 32 by means of adhesion, while the second buffer block 215 can be fixed to the surface of the base 213 facing the glass 32, i.e. to the surface of the base 213 facing the gland 212, by means of adhesion.

[0090] By providing the first buffer block 214 on the surface of the arc-shaped portion 2123 facing the glass 32, during the tightening of the gland 212 to the base 213, there is soft contact between the first buffer block 214 provided on the arc-shaped portion 2123 and the glass 32, so as to avoid damage to the glass 32 by particles, such as stones, adhering to the upper surface of the heating structure 1.

[0091] By providing the second buffer block 215 on the surface of the base 213 facing the frame 31, during the tightening of the gland 212 to the base 213, there is soft contact between the second buffer block 215 provided on the base 213 and the bottom of the frame 31, so as to avoid indentation or damage to the bottom of the frame 31 by particles, such as stones, adhering to the lower surface of the heating structure 1, thus protecting the frame 31.

[0092] Figure 9 Fig. 2 shows a schematic view of the assembly structure of the gland 212 according to some embodiments of the present application, Figure 10 Fig. 3 shows a schematic view of the assembly structure of the base 213 according to some embodiments of the present application.

[0093] In some embodiments, in combination with Figure 9 and Figure 10 as shown in the figures, the gland 212 comprises a plurality of gland portions 2124, which are assembled to form a first U-shaped structure;

[0094] The base 213 comprises a plurality of base portions 2132, which are assembled to form a second U-shaped structure.

[0095] In at least one embodiment, the gland 212 can have a multi-segment assembly structure, and the plurality of gland portions 2124 can be assembled to form a first U-shaped structure. Similarly, the base 213 can have a multi-segment assembly structure, and the plurality of base portions 2132 can be assembled to form a second U-shaped structure. Adjacent two of the gland portions 2124 can be assembled by means of, for example, a connecting plate, a clamp, a long bolt, or the like, and adjacent two of the base portions 2132 can also be assembled by means of, for example, a connecting plate, a clamp, a long bolt, or the like.

[0096] By setting the cover 212 and the base 213 in a multi-section splicing structure, the frame 31 of the photovoltaic module 3 of different specifications can be adapted, and the repair flexibility and versatility of the photovoltaic module 3 of different specifications are improved.

[0097] In some embodiments, the heating structure 1 has an L-shaped or U-shaped cross-sectional shape perpendicular to the extension direction of the pressing tool 2.

[0098] Specifically, the heating structure 1 has an L-shaped cross-sectional shape perpendicular to the extension direction of the pressing tool 2, for example, along Figure 11 the plane formed by the Y-axis and the Z-axis or the plane formed by the X-axis and the Z-axis in the coordinate system.

[0099] Figure 11 A structural schematic diagram of the heating structure 1 according to some embodiments of the present application.

[0100] In combination with Figure 11 the drawings, the heating structure 1 can adopt a structure mode as follows: the heating structure 1 includes a first heating part 11 and a second heating part 12 arranged at an included angle, the first heating part 11 is used to be attached to a first surface of the frame 31, the second heating part 12 is used to be attached to a second surface of the frame 31, and the first surface and the second surface are arranged at an included angle.

[0101] In at least one embodiment, the first heating part 11 and the second heating part 12 can be arranged at an included angle, and since the heating structure 1 can be made of a flexible heat-conducting material, the included angle of the first heating part 11 and the second heating part 12 can be greater than 0 degrees or less than or equal to 90 degrees.

[0102] The first surface of the frame 31 refers to the front surface (or top surface) of the frame 31, and the second surface of the frame 31 refers to the side surface of the frame 31; by attaching the first heating part 11 to the first surface (front surface) of the frame 31 and attaching the second heating part 12 to the second surface (side surface) of the frame 31, the front surface and the side surface of the frame 31 are heated by the first heating part 11 and the second heating part 12 respectively, and the heat of the first heating part 11 and the second heating part 12 is conducted to the laminated piece through the frame 31 to heat the delamination part of the laminated piece to solve the delamination problem.

[0103] Unlike the above-mentioned embodiments, the heating structure 1 has a U-shaped cross-sectional shape perpendicular to the extension direction of the pressing tool 2, for example, along Figure 12 the plane formed by the Y-axis and the Z-axis or the plane formed by the X-axis and the Z-axis in the coordinate system.

[0104] Figure 12 A structural schematic diagram of the heating structure 1 according to some embodiments of the present application.

[0105] Unlike the above embodiments, in some embodiments, in combination with Figure 12 As shown in FIG. 1, the heating structure 1 can also heat the bottom surface of the frame 31. Specifically, the heating structure 1 includes a first heating portion 11, a second heating portion 12, and a third heating portion 13. The first heating portion 11 and the third heating portion 13 are arranged at an angle with the second heating portion 12. The first heating portion 11 is used to be attached to the first surface of the frame 31. The second heating portion 12 is used to be attached to the second surface of the frame 31. The third heating portion 13 is used to be attached to the third surface of the frame 31. The first surface and the third surface are arranged at an angle with the second surface.

[0106] In at least one embodiment, as described above, the first surface of the frame 31 refers to the front surface (or top surface) of the frame 31, and the second surface of the frame 31 refers to the side surface of the frame 31. The third surface of the frame 31 refers to the bottom surface of the frame 31.

[0107] The third heating portion 13 can be parallel to the first heating portion 11, and the second heating portion 12 can be arranged between the first heating portion 11 and the third heating portion 13.

[0108] By attaching the first heating portion 11 to the first surface (front surface) of the frame 31, the second heating portion 12 to the second surface (side surface) of the frame 31, and the third heating portion 13 to the third surface of the frame 31, the front surface, the side surface, and the bottom surface of the frame 31 are simultaneously heated by the first heating portion 11, the second heating portion 12, and the third heating portion 13, respectively. The heat of the first heating portion 11, the second heating portion 12, and the third heating portion 13 is conducted to the laminated piece through the frame 31 to heat the delamination part of the laminated piece, thereby solving the delamination problem.

[0109] In some embodiments, in combination with Figure 2 and Figure 7 As shown in FIG. 1, part of the heating structure 1 extends out of the first mounting groove 211.

[0110] It should be noted that when the heating structure 1 is embedded in the first mounting groove 211, part of the heating structure 1 is in the first mounting groove 211, and the other part of the heating structure 1 extends out of the first mounting groove 211. The part of the heating structure 1 extending out of the first mounting groove 211 can completely cover the frame 31, so that the frame 31 embedded in the first mounting groove 211 can be completely heated by the heating structure 1. The frame 31 can conduct more heat conducted by the heating structure 1 to the edge of the laminated piece, so that the delamination part of the laminated piece can be completely repaired, thereby achieving the repair effect on the delamination problem of the photovoltaic module.

[0111] In some embodiments, the cover 212 and the base 213 are made of light weight material.

[0112] In at least one embodiment, the light weight material can be made of aluminum alloy or other alloy material, so that the cover 212 and the base 213 can be easily disassembled. As long as the material has certain mechanical strength and light weight, it is suitable for the technical solution, and is not limited herein.
