[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0022] It should be noted that the words “having”, “including”, “comprising”, etc. described in this application are all open-ended meanings, that is, when describing that a module “has”, “including”, or “comprising” a first element, a second element, and / or a third element, it means that the module includes other elements in addition to the first element, the second element, and / or the third element. In addition, ordinal numbers such as “first”, “second”, and “third” in this application are not intended to limit a specific order, but are only used to distinguish various parts.

[0023] The photovoltaic module disassembly device provided in the embodiment of the present invention can be used to disassemble photovoltaic modules such as lightweight photovoltaic modules or frameless double-glass modules, and can be specifically used to separate photovoltaic modules from fixed bodies, and part of the area between the photovoltaic modules and the fixed body is fixed by colloid. Photovoltaic modules are solar panels, and lightweight photovoltaic modules refer to photovoltaic products that are made of polymer encapsulation front panels, high water vapor barrier and low corrosion, low flow encapsulation films, and metal composite back panels with zero water vapor permeability, excellent weather resistance, high fire resistance and high strength, and are encapsulated by vacuum and high pressure, without metal frames or tempered glass design, and the modules do not need to be grounded, are lightweight and have high reliability. The fixed body can be the roof of a building, etc., but is not limited to this. Lightweight photovoltaic modules are generally fixed to the fixed body by colloid, and the colloid can be a structural adhesive. Structural adhesive is a neutral curing, high modulus, high strength, and high elasticity structural silicone sealant with excellent structural bonding performance and weather resistance and anti-aging performance. When used, it reacts with moisture in the air to solidify to form a long-term effective structural bonding and sealing elastic colloid.

Figure 2 A schematic diagram of the structure of a control component provided by an embodiment of the present invention, Figure 3 A schematic diagram of the structure of a cutting assembly provided by an embodiment of the present invention, Figure 4 A schematic diagram of a photovoltaic module disassembly device provided by an embodiment of the present invention is provided. Figure 5 A schematic diagram of another photovoltaic module disassembly device provided by an embodiment of the present invention. Figure 1-Figure 5 The photovoltaic module disassembly device includes a control component 100, a cutting component 200 and a driving component 300; the control component 100 includes an electrically connected power supply submodule 101 and a transmitting coil 102; the cutting component 200 includes a receiving coil 201 and a hot cutting head 202, the hot cutting head 202 and the receiving coil 201 are electrically connected, and the hot cutting head 202 is used to perform hot cutting on the colloid (not shown in the figure); the driving component 300 is used to control the cutting component 200 to move in the gap between the photovoltaic module 400 and the fixed body 500 when performing hot cutting.

[0025] like Figure 1 and Figure 2As shown, the control component 100 may be a control box, and the power supply submodule 101 and the transmitting coil 102 may be packaged in the control box. Figure 2 1 is a schematic diagram of the appearance structure of the control component 100, and the internal structure is not shown. The power supply submodule 101 and the transmitting coil 102 can constitute a power supply circuit, and the power supply submodule 101 is used to provide an electrical signal (which can be a current or a voltage), and a current is formed in the power supply circuit, and the current generates a magnetic field through the transmitting coil 102. Exemplarily, the power supply submodule 101 can be a DC power supply such as a battery, and the power supply circuit can also include an oscillation circuit, which is connected between the power supply submodule 101 and the transmitting coil 102. The oscillation circuit is used to convert the DC power into high-frequency AC power, and the high-frequency AC power generates a high-frequency changing magnetic field through the transmitting coil 102, or the power supply submodule 101 can be a 220V AC power supply, and the AC power generates a high-frequency changing magnetic field through the transmitting coil 102.

[0026] like Figure 2 As shown, the control assembly 100 may include switch structures such as a control button, a control switch, a reset switch, an emergency stop switch, and a warning light. The control button may be a power button of the control assembly 100, which can be used to control the start and stop of the photovoltaic assembly disassembly device. Handles may also be provided on both sides of the housing of the control assembly 100 to facilitate the staff to move the control assembly 100.

[0027] The transmitting coil 102 and the receiving coil 201 form a transformer structure. The hot cutting head 202 and the receiving coil 201 in the cutting assembly 200 can form a receiving circuit. When the receiving coil 201 in the cutting assembly 200 is within the magnetic field generated by the transmitting coil 102, an induced potential is generated, thereby forming an induced current, i.e., an eddy current, which flows through the hot cutting head 202. The hot cutting head 202 is a metal and can be regarded as a resistor in the receiving circuit. The induced current flowing through the hot cutting head 202 generates heat, thereby achieving the purpose of heating the hot cutting head 202. Figure 3 It is a schematic diagram of the appearance structure of the cutting assembly 200, and the receiving coil 201 is not shown.

[0028] like Figure 1-Figure 5 As shown, the driving assembly 300 and the cutting assembly 200 can be connected to the cutting assembly 200 by any transmission method. When performing thermal cutting, the driving assembly 300 can drive the cutting assembly 200 to move in the plane where the fixed body 500 is located. The colloid (not shown in the figure) in contact with the hot cutting blade 202 will soften, and the hot cutting blade 202 can easily cut the colloid, thereby separating the photovoltaic assembly 400 and the fixed body 500. The high temperature of the hot cutting blade 202 is used to soften the colloid first and then cut it. The photovoltaic assembly 400 and the adhesive surface are not affected by stress, and the purpose of non-destructive disassembly can be achieved. When performing thermal cutting, the driving assembly 300 can be placed outside the installation area of ​​the photovoltaic assembly 400.

[0029] One thing that needs to be noted is that during the disassembly process, the distance between the control component 100 and the cutting component 200 should be ensured to meet the distance requirements of the wireless power supply coil, that is, the receiving coil 201 should be located in the magnetic field generated by the transmitting coil 102, thereby ensuring the continuous heat generation of the hot cutting head 202.

[0030] For reference Figure 1-Figure 5 In general, the adhesive surface of the photovoltaic module 400 and the fixed body 500 will not be completely fixed by the colloid, and the strip-shaped extended colloid will only be provided in some areas. In the area where the colloid is not provided, there is a certain gap between the photovoltaic module 400 and the fixed body 500. In the embodiment of the present invention, the height of the cutting component 200 can be less than the height of the gap between the photovoltaic module 400 and the fixed body 500. When disassembling the photovoltaic module 400, the cutting component 200 can be placed in the gap between the photovoltaic module 400 and the fixed body 500, and then the control component 100 controls the hot cutting head 202 to heat up, and the driving component 300 controls the hot cutting head 202 to move, and the colloid part in contact with the hot cutting head 202 can be cut and peeled off.

[0031] The embodiment of the present invention does not limit the specific structure of the cutting assembly 200 and the driving assembly 300 and the driving mode of the two. Those skilled in the art can set them according to actual needs. Figure 3-Figure 5 Only alternatives are shown by way of example.

[0032] By setting up wireless power supply control components and cutting components, and using wireless power supply technology to power the cutting components, the photovoltaic module disassembly device can be flexibly arranged, thereby increasing the applicable scenarios of the photovoltaic module disassembly device. At the same time, the volume of the cutting component can be reduced, so that the cutting component can be flexibly moved in the gap between the photovoltaic module and the fixed body. Using thermal cutting technology to cut the colloid can achieve non-destructive disassembly of the photovoltaic module, avoid damage to the photovoltaic module and the fixed body, and improve the reuse rate of the photovoltaic module. The reuse rate of the photovoltaic module is as high as more than 95%, thereby reducing production costs, improving the maintenance and replacement efficiency of photovoltaic modules, and facilitating the promotion and application of solar energy utilization technology.

[0033] Optionally, in some embodiments, the control component and the drive component may be electrically connected, for example, via a wireless or limited electrical connection. The control component also includes a drive control submodule, which sends a drive control signal to the drive component, and the drive component drives the cutting component to move in response to the drive control signal.

[0034] In addition, in some embodiments, the control component also includes a temperature control submodule, which is electrically connected to the power supply submodule and the transmitting coil respectively. The temperature control submodule is used to control and adjust the temperature or power and control the switching of the power supply of the component.

[0035] The photovoltaic module disassembly device provided by the embodiment of the present invention includes a control component, a cutting component and a driving component; the control component includes an electrically connected power supply submodule and a transmitting coil; the cutting component includes a receiving coil and a hot cutting blade, the hot cutting blade and the receiving coil are electrically connected, and the hot cutting blade is used to perform hot cutting on the colloid; the driving component is used to control the movement of the cutting component in the gap between the photovoltaic module and the fixed body during hot cutting. Through the above scheme, the photovoltaic module disassembly device can be flexibly arranged, and the colloid is cut by using hot cutting technology, which can realize non-destructive disassembly of the photovoltaic module, avoid damage to the photovoltaic module and the fixed body, improve the reuse rate of the photovoltaic module, reduce production costs, and improve the maintenance and replacement efficiency of the photovoltaic module, which is conducive to the promotion and application of solar energy utilization technology.

[0036] Optional, you can continue to refer to Figure 3 In a possible embodiment, the cutting assembly 200 also includes a main body 203 and a cutter head mounting portion 204, the cutter head mounting portion 204 is located on the side of the main body 203 and is integrally arranged with the main body 203, and the cutter head mounting portion 204 and the main body 203 are connected in a step-like manner; the hot cutting cutter head 202 is fixed on the cutter head mounting portion 204, and the blade of the hot cutting cutter head 202 is away from the main body 203 along a direction parallel to the plane where the cutting assembly 200 is located.

[0037] like Figure 3 As shown, the main body 203 and the cutter head mounting portion 204 are an integral structure, and the two constitute the overall frame of the cutting assembly 200, and the cutter head mounting portion 204 is located on one side of the main body 203. The thickness of the cutter head mounting portion 204 along the thickness direction of the cutting assembly 200 is less than the thickness of the main body 203 along the thickness direction of the cutting assembly 200. The bottom surfaces of the cutter head mounting portion 204 and the main body 203 can be flush, and the top surface of the cutter head mounting portion 204 is lower than the top surface of the main body 203, thereby forming a stepped frame edge of the cutting assembly 200, the main body 203 is an upper step, and the cutter head mounting portion 204 is a lower step. Among them, the bottom surface refers to the side of the cutting assembly 200 close to the fixed body 500 during cutting, and the top surface refers to the side of the cutting assembly 200 away from the fixed body 500. In other words, the cutter head mounting portion 204 can be a lower step portion protruding from the main body 203 along the extension direction of the plane where the cutting assembly 200 is located and lower in height than the main body 203. Figure 3 The figure is a schematic structural diagram of one side of the top surface of the cutting assembly 200.

[0038] The hot cutting blade 202 can be fixed on the blade mounting portion 204 (i.e., the top surface), and the top surface of the hot cutting blade 202 can be flush with the top surface of the main body 203, thereby improving the aesthetics of the cutting assembly 200. The blade of the hot cutting blade 202 is away from the main body 203, that is, the edge side of the hot cutting blade 202 faces the outside of the cutting assembly 200, so that the blade is used to cut the colloid.

[0039] Among them, it should be noted that Figure 3 The hot cutting blade 202 is exemplarily shown to be installed on one side edge of the cutting assembly 200, but it is not limited thereto. In other embodiments not shown, the hot cutting blade 202 can be installed on both sides or even multiple sides of the cutting assembly 200. When the hot cutting blade 202 is installed on both sides or even multiple sides of the cutting assembly 200, the hot cutting blade 202 occupies a larger area, and the contact area with the colloid will also become larger, which is conducive to improving the cutting efficiency.

[0040] In the present invention, the cutting assembly 200 is taken as an example of a thin rectangular parallelepiped, but is not limited thereto. Taking the rectangular parallelepiped as an example, the cutter head mounting portion 204 is located on the short side of the main body 203 , and the hot cutting cutter head 202 is located on the short side edge of the cutting assembly 200 .

[0041] Optional, you can continue to refer to Figure 3 The hot cutting blade 202 and the main body 203 are arranged along the long side direction of the cutting assembly 200; the blade mounting portion 204 includes a first mounting portion 2041 and a second mounting portion 2042, the first mounting portion 2041 and the second mounting portion 2042 are arranged along the short side direction of the cutting assembly 200, and there is a gap S1 between the first mounting portion 2041 and the second mounting portion 2042; the hot cutting blade 202 includes an integrally arranged first connecting portion 2021, a second connecting portion 2022 and a cutting portion 2023, the first connecting portion 2021 is fixed on the first mounting portion 2041, the second connecting portion 2022 is fixed on the second mounting portion 2042, and the orthographic projection of the cutting portion 2023 on the plane where the cutting assembly 200 is located overlaps with the orthographic projection of the gap S1 on the plane where the cutting assembly 200 is located.

[0042] like Figure 3 As shown, the cutter head mounting portion 204 may include two mounting parts, namely a first mounting portion 2041 and a second mounting portion 2042. The first mounting portion 2041 and the second mounting portion 2042 are arranged along the short side direction of the cutting assembly 200, and there is a gap S1 between the first mounting portion 2041 and the second mounting portion 2042. In other words, the first mounting portion 2041 and the second mounting portion 2042 are symmetrically distributed along the central axis of the main body 203 in the long side direction. The side surface of the first mounting portion 2041 (the second mounting portion 2042) facing away from the second mounting portion 2042 (the first mounting portion 2041) is flush with the long side surface of the main body 203.

[0043] The hot cutting blade 202 is in the form of a rectangular blade. The position close to the edge of the hot cutting blade 202 along its extended length direction is a connecting portion (including a first connecting portion 2021 and a second connecting portion 2022), and the middle is a cutting portion 2023. The connecting portions are fixed one-to-one on the mounting portion, and the cutting portion 2023 is located at the gap S1 in the middle. The cutting portion 2023 plays the role of cutting the colloid, and the connecting portion plays the role of transmitting heat and fixing. After the receiving coil 201 forms an induced current, the induced current can be transmitted between the first connecting portion 2021 and the second connecting portion 2022, so that the hot cutting blade 202 can generate heat as a whole. Among them, the hot cutting blade 202 can be sharpened only at the cutting portion 2023, so that the resistance at the cutting portion 2023 is larger, the heat generation is higher, and the heating effect is better.

[0044] In addition, in this arrangement, the hot cutting blade 202 is located at the short edge of the cutting assembly 200, and the hot cutting blade 202 and the main body 203 are arranged along the long side direction of the cutting assembly 200. The driving assembly 300 can control the cutting assembly 200 to move along its long side direction so that the cutting portion 2023 of the hot cutting blade 202 is tangent to the cross section of the colloid, thereby completing the cutting and peeling of the colloid.

[0045] The connection part may be fixed to the corresponding installation part by means of connection components such as screws, and the embodiment of the present invention does not limit or elaborate on this.

[0046] In an optional embodiment of the present invention, the width of the cutting portion 2023 may be smaller than the width of the first connecting portion 2021 or the second connecting portion 2022, thereby increasing the resistance of the cutting portion 2023, increasing the heat generated by the cutting portion 2023, and improving the cutting efficiency.

[0047] like Figure 3 As shown, the cutting assembly 200 may further include a coil arrangement slot 209, and a receiving coil (not shown) may be arranged in the coil arrangement slot 209. The coil arrangement area 209 may be close to the area of ​​the cutter head mounting portion 204, for example, it may be arranged on the long side of the main body 203, and the receiving coil may be encapsulated in the coil arrangement slot 209. Of course, in actual application, the placement position of the receiving coil is not limited to this.

[0048] Optional, Figure 6 A schematic diagram of another cutting assembly provided in an embodiment of the present invention can be further referred to Figure 3-Figure 6In a possible embodiment, the fixing body 500 includes a plurality of mounting ribs 501 extending along a first direction X and arranged in a second direction Y, and a colloid (not shown in the figure) is disposed between the mounting ribs 501 and the photovoltaic module 400; the bottom surface of the main body 203 includes a receiving groove S2, the receiving groove S2 extends along the long side direction of the cutting assembly 200 and is connected to the gap S1, and the shape of the receiving groove S2 is complementary to the shape of the mounting ribs 501; when performing thermal cutting, the cutting assembly 200 is placed on the mounting ribs 501, the long side direction of the cutting assembly 200 is parallel to the first direction X, and the receiving groove S2 surrounds the mounting ribs 501; the driving assembly 300 controls the cutting assembly 200 to move along the first direction X.

[0049] like Figure 3-Figure 6 As shown, the fixing body 500 may be a corrugated roof, and the adhesive surface of the fixing body 500 includes a plurality of mounting convex ribs 501, and the mounting convex ribs 501 protrude from the plane of the fixing body 500. The colloid may be arranged on the mounting convex ribs 501, and the photovoltaic module 400 is fixed to the mounting convex ribs 501 through the colloid, that is, the colloid mentioned above extends in a strip shape.

[0050] Figure 6 is a schematic diagram of the structure of the bottom side of the cutting assembly 200, as shown in Figure 6 As shown, the bottom surface of the main body 203 includes a receiving groove S2, which extends from the bottom surface to the top surface by a certain height, and the receiving groove S2 penetrates the side walls of the main body 203 along the long side direction of the cutting assembly 200, that is, along the long side direction of the cutting assembly 200, one end of the receiving groove S2 is connected to the gap S1 between the two mounting parts (the first mounting part 2041 and the second mounting part 2042), and the other end extends to the other side surface of the main body 203 opposite to the blade mounting part 204. The lower surface of the mounting part can be flush with the lower surface of the main body 203 on both sides of the receiving groove S2 along the short side direction of the cutting assembly 200.

[0051] Continue to refer Figure 3-Figure 6 Before performing thermal cutting, i.e. disassembling the photovoltaic module 400, the cutting assembly 200 is placed on the mounting convex rib 501. The long side direction of the cutting assembly 200 is the extension direction (first direction X) of the mounting convex rib 501. The mounting convex rib 501 is just placed in the accommodating groove S2 and the gap S1. The cutting portion 2023 of the thermal cutting blade 202 is close to the upper surface of the mounting convex rib 501 and faces the colloid. Then the driving assembly 300 controls the cutting assembly 200 to move along the first direction X toward the area where the colloid is located. The mounting convex rib 501 can serve as a movable limiting structure of the cutting assembly 200, so that the cutting assembly 200 moves along the extension direction of the colloid. Thus, the colloid is thermally cut.

[0052] Optional, you can continue to refer to Figure 6In a possible embodiment, the cutting assembly 200 may further include an auxiliary fixing component 205; the auxiliary fixing component 205 is installed on the bottom surface of the main body 203, and the auxiliary fixing component 205 is located on both sides of the accommodating groove S2.

After the cutting assembly 200 is placed on the fixed body 500, the auxiliary fixing part 205 contacts the fixed body 500, thereby ensuring the stability of the movement of the cutting assembly 200 during cutting.

[0054] Among them, Figure 6 As shown, the auxiliary fixing components 205 can be installed on both sides of the receiving groove S2. When thermal cutting is performed, the auxiliary fixing components 205 are located on both sides of the mounting convex ribs 501 along the second direction.

[0055] The embodiment of the present invention does not limit the specific structure of the auxiliary fixing component 205. For example, in some embodiments, the auxiliary fixing component 205 may include at least one of a roller component, a magnetic component and a pneumatic clamp component.

[0056] Figure 6 The auxiliary fixing member 205 is exemplarily shown to be a roller member, which includes four rollers, which are arranged in pairs on both sides of the receiving groove S2. During the cutting process, the roller member contacts the plane area of ​​the fixing body 500, which can not only ensure the supporting effect of the fixing body 500 on the cutting assembly 200, but also facilitate the movement of the cutting assembly 200.

[0057] In other embodiments, the auxiliary fixing component 205 may also be a magnetic component or a pneumatic clamp component. The magnetic component is a component that uses the magnetic principle to connect and fix. The pneumatic clamp component uses air pressure to tighten and release the clamp. The magnetic component and the pneumatic clamp component can contact and fix with the mounting convex rib 501 of the fixed body 500, thereby realizing the smooth movement of the cutting assembly 200 along the mounting convex rib 501.

[0058] The specific structures of the magnetic attraction component and the pneumatic clamp component are not limited in the embodiments of the present invention, and those skilled in the art may select any existing technology to implement them according to actual needs.

The hot cutting cutter head 202 is fixed on the side of the metal base 207 away from the insulating structure 206, and the metal base 207 is connected to the receiving coil ( Figure 6 The metal base 207 is arranged in the insulating structure 206 to evenly distribute the electric field, thereby evenly distributing the induced current (eddy current), so that the induced current is evenly distributed to the hot cutting blade 202.

[0061] The metal base 207 may be a copper base, and the insulating structure 206 may be an insulating pad, but is not limited thereto.

[0063] like Figure 4 and Figure 5 As shown, the driving assembly 300 may optionally use a winch assembly, which is a light and small device that uses a drum to wind a traction rope 302 (such as a wire rope or chain) to lift or pull an object, and can lift vertically, horizontally or tilt the object.

[0064] The hoist body 301 is the main structure of the hoist, and the drum is located on the hoist body 301. When the photovoltaic module 400 is disassembled by using the photovoltaic module disassembly device, the hoist assembly and the cutting assembly 200 can be placed together on the fixed body 500, and one end of the traction rope 302 is wound on the drum, and the other end is connected to the cutting assembly 200. Among them, the hoist assembly can be located on at least one side of the cutting assembly 200 along the first direction X, and the traction rope 302 extends along the first direction X. The rotation of the drum can drive the cutting assembly 200 to move along the first direction X.

[0065] like Figure 3 As shown, the cutting assembly 200 includes a traction hook 208, which is arranged on the short side of the cutting assembly 200, for example, on the side of the cutter head mounting portion 204. The traction rope 302 is hung on the traction hook 208, thereby connecting the winch assembly to the cutting assembly 200.

[0066] You can continue to refer to Figure 4 and Figure 5 The driving assembly 300 includes two winch assemblies, which are respectively located on both sides of the cutting assembly 200 along the first direction X; the two winch assemblies are respectively connected to the same cutting assembly 200, and the traction directions of the two winch assemblies on the cutting assembly 200 are opposite.

[0067] like Figure 4 and Figure 5 As shown, a cutting assembly 200 can be driven by two hoist assemblies, and the two hoist assemblies are respectively located on both sides of the cutting assembly 200 along the first direction X. The hoist bodies 301 of the two hoist assemblies are both located outside the installation area of ​​the photovoltaic assembly 400. The traction ropes 302 of the two hoist assemblies are respectively connected to the two short side surfaces of the cutting assembly 200, and the traction forces of the two hoist assemblies on the cutting assembly 200 are opposite. When it is necessary to drive the cutting assembly 200 to move in the direction where one of the hoist bodies 301 is located, the hoist body 301 can use the corresponding traction rope 302 to provide tension to the cutting assembly 200, and the other hoist body 301 can use the corresponding traction rope 302 to provide thrust to the cutting assembly 200. Using two hoist assemblies to drive the cutting assembly 200 can further ensure that the cutting assembly 200 moves stably along the first direction X.

Of course, in other embodiments, the drive assembly 300 can also use any driving device, such as a motor belt assembly, a prefabricated guide rail under the belt, and the cutting assembly 200 is placed on the belt to perform forward cutting and disassembly along with the belt.
