[0021] Figure 1 A structural schematic view of a photovoltaic module disassembling device provided in the embodiments of the present application is shown in the figure, Figure 2 A structural schematic view of another photovoltaic module disassembling device provided in the embodiments of the present application is shown in the figure,Figure 3 The use schematic view of the photovoltaic module disassembling device is provided for the embodiment of the utility model, refer to Figures 1-3 , the photovoltaic module disassembling device includes cutting mechanism 100, cutting mechanism 100 includes bottom plate 10, cutting assembly 20 and moving assembly 30, and cutting assembly 20 and moving assembly 30 are fixed with bottom plate 10;Cutting assembly 20 includes hot cutting cutter head 21 (green part in the drawing), when hot cutting is carried out using cutting mechanism 100, hot cutting cutter head 21 contacts bonding glue (not shown in the drawing);Moving assembly 30 is installed on the first surface 11 of bottom plate 10, when hot cutting is carried out using cutting mechanism 100, the first surface 11 of bottom plate 10 faces fixed body 200, and moving assembly 30 drives cutting mechanism 100 to move in the gap between photovoltaic module (not shown in the drawing) and fixed body 200.

[0022] As Figures 1-3 Indicated, cutting mechanism 100 is the cutting structure of the photovoltaic module disassembling device, when the photovoltaic module disassembling device is used, cutting mechanism 100 can be placed on the side surface of the fixed body 200 and the photovoltaic module bonding.

[0023] Bottom plate 10 is the main part of cutting mechanism 100, cutting assembly 20 is the cutting part of cutting mechanism 100, moving assembly 30 is the moving part of cutting assembly 20, and cutting assembly 20 and moving assembly 30 are fixed on bottom plate 10. Bottom plate 10 includes first surface 11 and second surface 12 oppositely arranged along its thickness direction. Figure 2 As

[0024] Wherein, the fixed position of cutting assembly 20 is not limited, as long as the hot cutting cutter head 21 of cutting assembly 20 can contact the bonding glue when cutting mechanism 100 is used. Exemplarily, the hot cutting cutter head 21 can extend in a sheet shape, when the photovoltaic module disassembling device is used, cutting assembly 20 can be placed in the gap between the photovoltaic module and the fixed body 200, so that the hot cutting cutter head 21 faces the bonding glue, and the cutting edge of the hot cutting cutter head 21 is tangent to the cross section of the bonding glue. The bonding glue in contact with the hot cutting cutter head 21 will soften, so that the bonding glue is easily cut by the hot cutting cutter head 21, and the photovoltaic module and the fixed body 200 are separated. The bonding glue is softened by the high temperature of the hot cutting cutter head 21 and then cut, and the photovoltaic module and the bonding surface are not affected by stress, so that the purpose of non-destructive disassembly can be achieved.

[0025] The specific shape of the hot cutting cutter head 21 is not limited, and the person skilled in the art can set it according to the actual needs, Figure 1 And Figure 2 In the embodiment shown, the hot cutting cutter head 21 is in the shape of a rectangular sheet as a whole, with a hollow in the middle, which is not limited in practice.

[0026] The moving assembly 30 is fixed on the first surface 11 of the base plate 10, and is located on the side surface of the base plate 10 facing the fixing body 200 after the cutting mechanism 100 is placed on the surface of the fixing body 200. The moving assembly 30 can drive the cutting mechanism 100 to move in the gap between the photovoltaic assembly and the fixing body 200. The moving assembly 30 can include a driving motor 31 and a moving wheel, but is not limited to this. By integrating the moving assembly 30 and the cutting assembly 20 in the cutting mechanism 100, the cutting mechanism 100 can be self-driven, thereby improving the integration and portability of the photovoltaic assembly disassembling device, and making the photovoltaic assembly disassembling device more widely applicable.

[0027] During the movement of the cutting mechanism 100, the adhesive glue in contact with the hot cutting head 21 can be softened, and the hot cutting head 21 can easily cut the adhesive glue, thereby separating the photovoltaic assembly and the fixing body 200. By using the high temperature of the hot cutting head 21 to soften the adhesive glue and then cutting it, the photovoltaic assembly and the pasting surface are not affected by stress, and the purpose of non-destructive disassembly can be achieved.

[0028] The cutting mechanism 100 can further include a heating module (not shown in the figure), which is connected with the hot cutting head 21 to heat the hot cutting head 21 to generate heat.

[0029] For example, the hot cutting head 21 can be powered by wired or wireless power supply, and the embodiments of the present application do not limit this. When the wireless power supply is used, the heating module can include a receiving coil, and the photovoltaic assembly disassembling device can further include a transmitting coil, which can be independently provided. The transmitting coil is used to generate a magnetic field, and the transmitting coil and the receiving coil in the cutting mechanism 100 form a transformer structure. When the receiving coil in the cutting mechanism 100 is within the magnetic field generated by the transmitting coil, an induced electromotive force is generated, thereby forming an induced current, i.e. eddy current. The hot cutting head 21 is metal, which can be regarded as a resistance in the circuit, and the induced current flowing through the hot cutting head 21 causes the hot cutting head 21 to generate heat. When the wired power supply is used, the heating module can be fixed with the base plate 10, and the heating module provides current to the hot cutting head 21, thereby causing the hot cutting head 21 to generate heat.

[0030] Of course, in actual application, the heating mode of the hot cutting head 21 is not limited to this, and any structure capable of controlling the heating of the hot cutting head 21 is within the scope of the technical solutions protected by the embodiments of the present application.

[0031] The photovoltaic module disassembling device provided by the utility model has high integration and portability, and has a wider application range.

[0032] Figure 4 A structure diagram of another photovoltaic module disassembling device provided by the utility model embodiment, Figure 4 An exploded view of the cutting assembly 20 is shown, referring to Figure 4 In some embodiments, the cutting assembly 20 can further include a first fixed plate 22, a second fixed plate 23 and a heat-conducting block 24. Along the thickness direction of the bottom plate 10, the first fixed plate 22 and the second fixed plate 23 are respectively arranged on the two sides of the hot cutting cutter head 21, and the heat-conducting block 24 can be positioned between the hot cutting cutter head 21 and the first fixed plate 22 or between the hot cutting cutter head 21 and the second fixed plate 23. Figure 4 In the embodiment, the second fixed plate 23 is close to the first surface of the bottom plate 10, and the heat-conducting block 24 is fixed between the hot cutting cutter head 21 and the second fixed plate 23, but the actual application is not limited thereto.

[0033] The heat-conducting block 24 is connected with a heating module (not shown in the figure), and the heating module transmits a heating current to the hot cutting cutter head 21 through the heat-conducting block 24, so as to improve the heating efficiency of the hot cutting cutter head 21. The number of the heat-conducting block 24 can be 2, and the two heat-conducting blocks 24 are respectively arranged on the two sides of the hot cutting cutter head 21 along the extension direction thereof, so as to ensure the formation of a heating loop.

[0034] Optionally, the first fixed plate 22 and the second fixed plate 23 can be glass fiber plates, and the heat-conducting block 24 can be a heat-conducting copper block, but the application is not limited thereto.

[0035] Optionally, the first fixed plate 22 and the second fixed plate 23 can be glass fiber plates, and the heat-conducting block 24 can be a heat-conducting copper block, but the application is not limited thereto. Figures 1-3In some embodiments, the fixing body 200 includes multiple mounting protrusions 201 extending along a first direction X and arranged in a second direction Y, and adhesive is disposed between the mounting protrusions 201 and the photovoltaic module (not shown in the figure); the base plate 10 includes a first portion 13 and a second portion 14 symmetrically arranged along the central axis of the base plate 10, and at least a portion of the area between the first portion 13 and the second portion 14 has a receiving gap 15, which penetrates the base plate 10 along the thickness direction of the base plate 10; the receiving gap 15 includes a first end and a second end arranged opposite to each other along the extending direction of the receiving gap 15, the first end communicating with one side of the base plate 10, and the hot cutting head 21 is fixed at the second end, with the cutting edge of the hot cutting head 21 facing the receiving gap 15; during hot cutting, the adhesive is located in the receiving gap 15, and the moving component 30 drives the cutting mechanism 100 to move along the first direction X.

[0036] like Figures 1-3 As shown, the fixing body 200 can be a corrugated roof. The adhesive surface of the fixing body 200 includes multiple mounting ribs 201, which protrude from the plane of the fixing body 200. Adhesive (not shown in the figure) can be applied to the mounting ribs 201. The photovoltaic module (not shown in the figure) is fixed to the mounting ribs 201 by the adhesive. The adhesive extends in strips. In areas where no adhesive is applied, there is a certain gap between the photovoltaic module and the fixing body 200. The height of the cutting mechanism 100 (height along the thickness direction of the base plate 10) can be less than the height of the gap between the photovoltaic module and the fixing body 200. When disassembling the photovoltaic module, the cutting mechanism 100 can be placed in the gap between the photovoltaic module and the fixing body 200. Then, the hot cutting head 21 is heated, and the moving component 30 is used to control the movement of the cutting mechanism 100. The adhesive in contact with the hot cutting head 21 can be cut and peeled off.

[0037] The base plate 10 has a rectangular overall shape and includes a symmetrically arranged first portion 13 and second portion 14. The first portion 13 and the second portion 14 are arranged along the plane of the base plate 10, and a portion of the area between them is connected by a connecting portion 16, while the other portions are spaced apart. A receiving gap 15 is located at the spaced interval between the first portion 13 and the second portion 14. The first end of the receiving gap 15 is connected to the side of the base plate 10, and the other end of the receiving gap 15 extends to the middle of the base plate 10. In other words, the receiving gap 15 can be regarded as a through groove in the middle area of ​​the base plate 10, extending from one side of the base plate 10 along the side length direction towards the middle.

[0038] The cutting assembly 20 can be fixed at the second end of the accommodating gap 15, and the cutting edge of the hot cutting head 21 faces the accommodating gap 15. In this way, when the hot cutting is performed by using the photovoltaic module disassembling device, the cutting mechanism 100 is placed above the mounting convex ridge 201, and the adhesive is in the accommodating gap 15. The moving assembly 30 drives the cutting mechanism 100 to move along the extension direction of the mounting convex ridge 201. The hot cutting head 21 at the second end of the accommodating gap 15 can perform hot cutting on the adhesive in front of the moving direction.

[0039] It should be noted that the width of the accommodating gap 15 in the second direction Y should be greater than the width of the adhesive in the second direction Y, so that the uncut adhesive can enter the accommodating gap 15.

[0040] By installing the cutting assembly 20 at the middle position of the bottom plate 10 and setting the accommodating gap 15, during the cutting process, the adhesive in the accommodating gap 15 and not cut can play a certain auxiliary moving role, thereby improving the stability of the cutting mechanism 100 when moving.

[0041] Optionally, in other embodiments of the utility model, the cutting assembly 20 can be fixed on at least one side wall of the bottom plate 10, so that the cutting assembly 20 can contact the adhesive. In this way, the accommodating gap 15 does not need to be set in the bottom plate 10. The process difficulty of the bottom plate 10 can be reduced. The utility model does not make detailed description for this setting mode.

[0042] Optionally, referring to Figure 2 continuously, the moving assembly 30 includes a driving motor 31 and a first moving wheel 32, the driving motor 31 is in transmission connection with the first moving wheel 32; the orthographic projection of the first moving wheel 32 on the plane where the bottom plate 10 is located is located at least one side of the accommodating gap 15; when the hot cutting is performed, the first moving wheel 32 contacts the mounting convex ridge 201, the driving motor 31 controls the first moving wheel 32 to rotate, and the first moving wheel 32 rotates to drive the cutting mechanism 100 to move.

[0043] As shown in Figure 2 , the driving motor 31 and the first moving wheel 32 can be fixed on the first surface 11 of the bottom plate 10, the driving motor 31 is in transmission connection with the first moving wheel 32, and the driving motor 31 can control the first moving wheel 32 to rotate. The first moving wheel 32 can be installed at the position close to the accommodating gap 15 of the first part 13 and / or the second part 14, so that the orthographic projection of the first moving wheel 32 on the plane where the bottom plate 10 is located is located at least one side of the accommodating gap 15.

[0044] After the cutting mechanism 100 is placed above the mounting protrusion 201, the first moving wheel 32 is in contact with the side surface of the mounting protrusion 201, the mounting protrusion 201 can serve as the support surface of the first moving wheel 32, the driving motor 31 drives the first moving wheel 32 to rotate, so that the cutting mechanism 100 can move along the extension direction of the mounting protrusion 201. The driving motor 31 can be a DC speed reduction motor, but is not limited thereto.

[0045] By taking the mounting protrusion 201 as the support surface of the first moving wheel 32, it can be ensured that the cutting mechanism 100 moves along the first direction X to cut the adhesive.

[0046] Figure 2 The driving motor 31 and the first moving wheel 32 are exemplarily shown as being installed on one of the subparts of the bottom plate 10 (for example, the first subpart 13), and being fixed to the same subpart, but are not limited thereto. In this arrangement, the first moving wheel 32 is close to the driving motor 31, which is conducive to reducing the connection difficulty between the two. In the process of thermal cutting, the first moving wheel 32 is in contact with one side surface of the mounting protrusion 201. In addition, Figure 2 The number of the first moving wheels 32 is exemplarily shown as being 2, and the two first moving wheels 32 are arranged in front of and behind each other, but are not limited thereto.

[0047] Optionally, with continued reference to Figure 2 The moving assembly 30 can further include a second moving wheel 33, the second moving wheel 33 is installed on the first surface 11 of the bottom plate 10, and the second moving wheel 33 is symmetrically arranged with the first moving wheel 32 on both sides of the receiving gap 15; in the process of thermal cutting, the second moving wheel 33 is in contact with the mounting protrusion 201 in the receiving gap 15.

[0048] When the first moving wheel 32 is installed on the first subpart 13 of the bottom plate 10, the second moving wheel 33 can be installed on the second subpart 14 of the bottom plate 10 and symmetrically arranged with the first moving wheel 32 on both sides of the receiving gap 15. The first moving wheel 32 and the second moving wheel 33 include a gap therebetween, which is used to accommodate the mounting protrusion 201.

[0049] In the process of thermal cutting, the cutting mechanism 100 is placed on the mounting protrusion 201, and the mounting protrusion 201 is in the gap between the first moving wheel 32 and the second moving wheel 33. Along the second direction Y, the first moving wheel 32 and the second moving wheel 33 are in contact with the opposite side surfaces of the mounting protrusion 201, respectively. The mounting protrusion 201 also serves as the support surface of the second moving wheel 33, the second moving wheel 33 is not connected with the driving motor 31, and the existence of the second moving wheel 33 can play a role in assisting movement and ensuring the cutting mechanism 100 to move along the extension direction of the mounting protrusion 201.

[0050] For example, the first moving wheels 32 and the second moving wheels 33 can be arranged in one-to-one correspondence and in the same number. When the number of the first moving wheels 32 is two, the second moving wheels 33 also include two wheels arranged in front and back.

[0051] Optionally, in some embodiments, the second moving wheels 33 can be fixed to the bottom plate 10 by elastic pressing members 34, and the elastic force of the elastic pressing members 34 is parallel to the arrangement direction of the first moving wheels 32 and the second moving wheels 33.

[0052] The elastic pressing member 34 is a component that uses the elastic deformation of a material to generate a pressing force. Taking the case that the second moving wheels 33 are arranged in the second part 14, the elastic pressing member 34 is fixed to the second part 14, and the elastic force of the elastic pressing member 34 is parallel to the arrangement direction of the first part 13 and the second part 14. In this way, when the cutting mechanism 100 is placed above the mounting convex 201, the second moving wheels 33 have a certain pressing force on the mounting convex 201 under the action of the elastic pressing member 34, which is beneficial to ensure the stable movement of the cutting assembly 20 during cutting.

[0053] Optionally, in other embodiments, the first moving wheels 32 can be installed on the first part 13 and the second part 14, and at this time, the second moving wheels 33 described above can be replaced by the first moving wheels 32, so that the wheels on both sides of the accommodation gap 15 are driven by the driving motor 31, thereby improving the moving speed.

[0054] Further reference can be made to Figure 2 In some embodiments, the moving assembly 30 further includes a third moving wheel 35, the third moving wheel 35 and the first moving wheel 32 are drivingly connected through a synchronous belt 36, and the third moving wheel 35 is drivingly connected with the driving motor 31.

[0055] In this embodiment, the moving assembly 30 can adopt a synchronous belt driving system, the first moving wheel 32 is a driven pulley of the belt, and the third moving wheel 35 is a driving pulley of the belt. The third moving wheel 35 is directly or indirectly connected with the driving motor 31, and the third moving wheel 35 and the first moving wheel 32 are closely connected through the synchronous belt 36. When the driving motor 31 drives the third moving wheel 35 to rotate, the synchronous belt 36 moves accordingly and drives the first moving wheel 32 to rotate at the same speed, thereby realizing synchronous transmission of motion and power.

[0056] The synchronous belt driving system has high-efficiency and precise transmission performance, and combines the advantages of various transmission modes, which is beneficial to the stable and fast movement of the cutting mechanism 100.

[0057] Optionally, in some other embodiments, the first moving wheel 32 can also be directly connected in transmission with the driving motor 31, for example, the first moving wheel 32 is directly connected with the output shaft of the driving motor 31, and the embodiments of the utility model do not make detailed description on this. Any kind of means capable of realizing that the driving motor 31 drives the first moving wheel 32 to rotate is within the technical scheme range protected by the embodiments of the utility model.
