Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0018] It should be noted that the terms "having," "comprising," and "including" used in this application have open-ended meanings. That is, when a module is described as "having," "comprising," or "including" a first element, a second element, and / or a third element, it means that the module includes other elements in addition to the first, second, and / or third elements. Furthermore, the ordinal numbers "first," "second," and "third" used in this application are not intended to specify a specific order, but only to distinguish between the various parts.

[0019] This utility model embodiment provides a cutting component suitable for photovoltaic module disassembly devices. These devices can be used to disassemble lightweight photovoltaic modules or frameless double-glass modules, with a portion of the photovoltaic module fixed to the mounting body using an adhesive. Lightweight photovoltaic modules refer to photovoltaic products made using a polymer-encapsulated front panel, a high-moisture barrier and low-corrosion, low-flow encapsulating film, and a metal composite back panel with zero water vapor transmission, excellent weather resistance, high fire resistance, and high strength, sealed under vacuum and high pressure. They feature a frameless design, no tempered glass, no need for grounding, and are lightweight and highly reliable. The mounting body can be a building roof, but is not limited to these. Lightweight photovoltaic modules are generally fixed to the mounting body using an adhesive, which can be a structural adhesive. The structural adhesive is a neutral-curing, high-modulus, high-strength, and highly elastic structural silicone sealant with excellent structural bonding performance and weather resistance. During use, it reacts with moisture in the air to cure, forming a long-lasting and effective structural adhesive sealant.

[0020] Figure 1 This is a schematic diagram of the structure of a cutting component according to an embodiment of the present invention. Figure 2 This is a schematic diagram illustrating the operation of a cutting component according to an embodiment of the utility model. The cutting component 10 is a component in a photovoltaic module disassembly device. The cutting component 10 is a thermal cutting component capable of thermally cutting the adhesive (not shown in the figure) between the photovoltaic module 20 and the fixing body 30. Figure 1As shown, the cutting assembly 10 includes a hot cutting blade 1 and a power supply module (not shown in the figure). The hot cutting blade 1 and the power supply module are electrically connected to form a heating circuit. The hot cutting blade 1 includes an integrally formed edge portion 11 and a cutting portion 12. The edge portion 11 and the cutting portion 12 are connected in series in the heating circuit. When hot cutting is performed using the cutting assembly 10, at least a portion of the cutting portion 12 is in contact with the colloid. The cross-sectional area of ​​the cutting portion 12 is smaller than the cross-sectional area of ​​the edge portion 11. The cross-sectional area represents the cross-sectional area of ​​the hot cutting blade 1 cut by a plane perpendicular to the direction of current movement.

[0021] like Figure 1 As shown, the cutting assembly 10 includes a hot-cutting blade 1 and a power supply module. The power supply module is used to provide current to the heating circuit, and the current flows through the hot-cutting blade 1. The hot-cutting blade 1 is made of metal and can be regarded as a resistor in the heating circuit. The current flowing through the hot-cutting blade 1 will generate heat, thereby achieving the purpose of heating the hot-cutting blade 1. Figure 1 This is a schematic diagram of the external structure of the cutting component 10; the power supply module is not shown.

[0022] Among them, the hot cutting blade 1 is made of nickel-chromium alloy material with good thermal conductivity and durability, but is not limited to this.

[0023] This utility model embodiment does not limit the specific method by which the power supply module supplies power to the hot cutting blade 1; those skilled in the art can set it according to actual needs. For example, in some embodiments, the power supply module may include components such as a power source, which provides current to the hot cutting blade 1. In another embodiment, the power supply module may include a receiving coil, and the photovoltaic module dismantling device further includes a control component 40, which may include a power source and a transmitting coil. The power source and the transmitting coil can form a power supply circuit, where the power source provides an electrical signal (which may be current or voltage), forming a current in the power supply circuit. This current generates a magnetic field through the transmitting coil. The transmitting coil and the receiving coil in the cutting assembly 10 form a transformer structure. When the receiving coil in the cutting assembly 10 is within the magnetic field range generated by the transmitting coil 102, an induced electromotive force is generated, thereby forming an induced current, i.e., an eddy current, which flows through the hot cutting blade 1.

[0024] Continue to refer to Figure 1 and Figure 2When using the cutting component 10 to thermally cut the adhesive, the cutting component 10 can be placed in the gap between the photovoltaic module 20 and the fixing body 30, with the hot cutting blade 1 facing the adhesive and the plane of the hot cutting blade 1 parallel or approximately parallel to the plane of the photovoltaic module 20, so that the hot cutting blade 1 and the horizontal cross-section of the adhesive form a zero-angle. The adhesive in contact with the hot cutting blade 1 will soften, thus allowing the hot cutting blade 1 to easily cut the adhesive and separate the photovoltaic module 20 and the fixing body 30. By using the high temperature of the hot cutting blade 1 to soften the adhesive before cutting, the photovoltaic module 20 and the adhesive surface are unaffected by stress, achieving the purpose of non-destructive disassembly.

[0025] The photovoltaic module dismantling device may further include a drive component 50, which is connected to the cutting component 10 to control the movement of the cutting component 10 within the gap between the photovoltaic module 20 and the fixing body 30 during thermal cutting. The moving direction of the cutting component 10 may be parallel to the extension direction of the colloid, thereby allowing the drive component 50 to drive the cutting component 10 to cut the colloid at different locations.

[0026] like Figure 1 and Figure 2 As shown, the fixing body 30 can be a corrugated roof. The adhesive surface of the fixing body 30 includes multiple mounting ribs 301, which protrude from the plane of the fixing body 30. Adhesive can be applied to the mounting ribs 301. The photovoltaic module 20 is fixed to the mounting ribs 301 by the adhesive, which extends in a strip shape. In areas where no adhesive is applied, there is a certain gap between the photovoltaic module 20 and the fixing body 30. In this embodiment, the height of the cutting component 10 can be less than the height of the gap between the photovoltaic module 20 and the fixing body 30. When disassembling the photovoltaic module 20, the cutting component 10 can be placed in the gap between the photovoltaic module 20 and the fixing body 30. Then, the hot-cutting blade 1 is heated, and the driving component 50 controls the movement of the hot-cutting blade 1. The adhesive in contact with the hot-cutting blade 1 can be cut and peeled off.

[0027] Furthermore, such as Figure 1 As shown, the hot-cutting blade 1 includes an edge portion 11 and a cutting portion 12. The edge portion 11 and the cutting portion 12 can be integrally formed or spliced ​​together, and this embodiment of the present invention does not limit this. The cutting portion 12 and the edge portion 11 are connected along the direction of current flow in the heating circuit, and the cutting portion 12 can be close to the power supply module.

[0028] The cutting section 12 refers to the main cutting area when cutting the colloid, that is, the cutting section 12 is the blade structure that mainly contacts the colloid. The edge section 11 connects the cutting section 12 and the power supply module and can serve to transmit current. It is worth mentioning that, in this embodiment, the cross-sectional area of ​​the cutting section 12 can be set to be smaller than the cross-sectional area of ​​the edge section 11. The cross-sectional area of ​​the cutting section 12 can refer to the cross-sectional area obtained by cutting the cutting section 12 with a plane perpendicular to the arrangement direction of the cutting section 12 and the edge section 11, and the cross-sectional area of ​​the edge section 11 can refer to the cross-sectional area obtained by cutting the edge section 11 with a plane perpendicular to the arrangement direction of the cutting section 12 and the edge section 11.

[0029] According to Joule's law, the heat generated by a conductor is Q = I^2Rt, where I is the current flowing through the conductor and R is the resistance of the conductor. The greater the resistance of the conductor, the greater the heat generated. Furthermore, according to the law of resistance, the resistance of a conductor is R = ρL / S, where ρ is the resistivity of the material used to make the resistor, L is the length of the wire used to make the resistor, and S is the cross-sectional area of ​​the wire used to make the resistor. The larger the cross-sectional area of ​​the conductor, the greater its resistance.

[0030] Based on the above analysis, this embodiment can increase the resistance of the cutting part 12 by reducing the cross-sectional area of ​​the cutting part 12, thereby increasing the heat generated by the cutting part 12 and improving the thermal cutting efficiency.

[0031] This utility model embodiment does not limit the specific shape of the hot cutting blade 1. Any shape that satisfies the requirement that the cross-sectional area of ​​the cutting part 12 is smaller than the cross-sectional area of ​​the edge part 11 is within the scope of the technical solution protected by this utility model embodiment.

[0032] In this embodiment of the invention, the cutting component 10 is used to thermally cut the colloid, enabling non-destructive disassembly of the photovoltaic module 20. This avoids damage to the photovoltaic module 20 and the fixing body 30, improves the reusability of the photovoltaic module 20, reduces production costs, and enhances the maintenance and replacement efficiency of the photovoltaic module 20, which is beneficial for the promotion and application of solar energy utilization technology. Furthermore, by structurally designing the hot-cutting blade 1, the heating temperature of the cutting section 12 of the hot-cutting blade 1 can be further increased, which is beneficial for the hot-cutting operation and thus improves the hot-cutting efficiency.

[0033] Optional, you can continue to refer to Figure 1 In a possible embodiment, the cutting assembly 10 may further include a main body 2 and a blade mounting portion 3 located on at least one side of the main body 2; the edge portion 11 is fixed to the blade mounting portion 3, and the orthographic projection of the cutting portion 12 on the plane where the cutting assembly 10 is located does not overlap with the orthographic projection of the blade mounting portion 3 on the plane where the cutting assembly 10 is located; the power supply module (not shown in the figure) is installed inside the main body 2.

[0034] like Figure 1As shown, the cutter head mounting part 3 is located on the side of the main body 2 and can be integrally formed with the main body 2, together constituting the overall frame of the cutting assembly 10. The main body 2 and the cutter head mounting part 3 are an integral structure, with the cutter head mounting part 3 located on one side of the main body 2. The thickness of the cutter head mounting part 3 along the thickness direction of the cutting assembly 10 is less than the thickness of the main body 2 along the thickness direction of the cutting assembly 10. The bottom surfaces of the cutter head mounting part 3 and the main body 2 can be flush, and the top surface of the cutter head mounting part 3 is lower than the top surface of the main body 2, thereby forming a stepped edge of the frame of the cutting assembly 10. The main body 2 is the upper step, and the cutter head mounting part 3 is the lower step. Here, the bottom surface refers to the side of the cutting assembly 10 that is close to the fixing body 30 during cutting, and the top surface refers to the side of the cutting assembly 10 that is away from the fixing body 30. In other words, the cutter head mounting part 3 can be a lower step portion that protrudes from the main body 2 along the extension direction of the plane where the cutting assembly 10 is located and is lower than the height of the main body 2. Figure 1 The diagram shown is a structural schematic of one side of the top surface of the cutting component 10.

[0035] The edge 11 of the hot-cutting blade 1 can be fixed to the blade head mounting part 3 (i.e., the top surface), and the edge 11 also serves to fix the hot-cutting blade 1 to the blade head mounting part 3. The power supply module can be encapsulated in the main body 2 near the blade head mounting part 3 to facilitate the connection between the power supply module and the hot-cutting blade 1.

[0036] The top surface of the hot-cutting blade 1 can be flush with the top surface of the main body 2, thereby improving the aesthetics of the cutting assembly 10. The cutting edge of the hot-cutting blade 1 faces away from the main body 2, that is, the sharpened side of the hot-cutting blade 1 faces the outside of the cutting assembly 10, thereby cutting the colloid using the cutting edge. It should be noted that... Figure 1 The illustration shows the hot-cutting blade 1 mounted on one side edge of the cutting assembly 10, but it is not limited to this. In other embodiments not shown, the hot-cutting blade 1 may be mounted on both sides or even multiple sides of the cutting assembly 10.

[0037] In this invention, the cutting assembly 10 is exemplified by having a relatively thin cuboid shape, but the design is not limited to this. Taking the cuboid as an example, the blade mounting part 3 is located on the short side of the main body 2, and the hot-cutting blade 1 is located on the short edge of the cutting assembly 10. The driving assembly 50 can control the cutting assembly 10 to move along its long side, so that the cutting part 12 of the hot-cutting blade 1 is tangent to the cross-section of the colloid, thereby completing the cutting and peeling of the colloid.

[0038] Continue to refer to Figure 1 This embodiment further specifies that the cutting part 12 can protrude from the blade mounting part 3 along the direction of the plane where the cutting assembly 10 is located, so that the orthographic projection of the cutting part 12 on the plane where the cutting assembly 10 is located does not overlap with the orthographic projection of the blade mounting part 3 on the plane where the cutting assembly 10 is located. In this way, it is convenient for the hot cutting blade 1 to perform hot cutting along the extension direction of the colloid.

[0039] Optional, you can continue to refer to Figure 1 In a possible embodiment, the hot-cutting blade 1 is rectangular in shape, and the edge portion 11 includes a first edge portion 111 and a second edge portion 112, which are located on both sides of the cutting portion 12 along the first direction X; the width of the cutting portion 12 along the second direction Y is smaller than the width of the first edge portion 111 along the second direction Y and smaller than the width of the second edge portion 112 along the second direction Y; the first direction X is the direction of the long side of the hot-cutting blade 1, and the second direction Y is the direction of the short side of the hot-cutting blade 1.

[0040] like Figure 1 As shown, the hot-cutting blade 1 is generally rectangular in shape. Along its long side (i.e., the first direction X), the portions near its two edges are the first edge portion 111 and the second edge portion 112. The portion between the first edge portion 111 and the second edge portion 112 is the cutting portion 12. The arrangement direction of the first edge portion 111, the cutting portion 12, and the second edge portion 112 is the direction of current flow, i.e., the first direction X. The length of the hot-cutting blade 1 along the first direction X is the length of the resistor. The hot-cutting blade 1 is cut with a plane perpendicular to the first direction X and parallel to the second direction Y to obtain the cross-section of the hot-cutting blade 1.

[0041] In this embodiment, the overall thickness of the hot-cutting blade 1 (the thickness in the direction perpendicular to the plane of the cutting assembly 10) can remain unchanged, that is, the thicknesses of the edge portion 11 and the cutting portion 12 are similar or the same. By adjusting the widths of the edge portion 11 and the cutting portion 12 along the second direction Y, the cross-sectional areas of the cutting portion 12 and the edge portion 11 can be differentiated.

[0042] Specifically, such as Figure 1 As shown, the first edge portion 111 and the second edge portion 112 can be configured to be wider along the second direction Y, while the cutting portion 12 can be narrower along the second direction Y. That is, the hot-cutting blade 1 has a structure that is wide at first, then narrow, and then wide again. This ensures that the cross-sectional area of ​​the cutting portion 12 in the middle is small, the resistance is large, and the heat generation of the cutting portion 12 is increased. In addition, by making both the first edge portion 111 and the second edge portion 112 wider, the fixing strength between the hot-cutting blade 1 and the blade mounting portion 3 can also be increased.

[0043] Correspondingly, the cutter head mounting portion 3 may include a first mounting portion 31 and a second mounting portion 32 arranged along the first direction X, and there is a gap between the first mounting portion 31 and the second mounting portion 32; in other words, the first mounting portion 31 and the second mounting portion 32 are symmetrically distributed along the central axis of the main body portion 2 in the second direction Y. The first edge portion 111 is fixed on the first mounting portion 31, the second edge portion 112 is fixed on the second mounting portion 32, and the orthographic projection of the cutting portion 12 on the plane where the cutting assembly 10 is located overlaps with the orthographic projection of the gap on the plane where the cutting assembly 10 is located.

[0044] Among them, the edge portion 11 can be fixed to the corresponding cutter head mounting portion 3 through connecting components such as screws. The embodiments of the present invention are not limited to this and will not be elaborated.

[0045] Figure 3 It is a schematic structural diagram of a hot cutting blade provided by an embodiment of the present invention. Figure 3 As shown in the plan view of the hot cutting blade 1, reference can be made in combination with Figure 1 and Figure 3 , the hot cutting blade 1 further includes a cutting edge side 13 and a blade back side 14 arranged oppositely along the second direction Y. When performing hot cutting using the cutting assembly 10, the cutting edge side 13 faces the colloid; the cutting edge side 13 extends linearly along the first direction X, and the blade back side 14 extends in a shape similar to a "Ji" character.

[0046] As Figure 1 and Figure 3 shown, in this embodiment, the hot cutting blade 1 can be sharpened only on the side背离 the main body portion 2. The sharpened side is the edge of the hot cutting blade 1 on the side背离 the main body portion 2, and the blade back side 14 is the edge of the hot cutting blade 1 on the side facing the main body portion 2. The blade back side 14 does not need to be sharpened. Figure 3 The circular pattern on the hot cutting blade 1 in

[0047] represents the area where the hot cutting blade 1 is fixed to the cutter head mounting portion.

[0048] In this setting method, it is equivalent to adjusting the width of the cutting portion 12 by setting a "Ji" character-shaped groove on the blade back side of the hot cutting blade 1.

[0049] Optionally, continue to refer to Figure 3The back of the blade 14 includes a first edge side 141, a concave side 142, and a second edge side 143 connected in sequence. The first edge side 141 and the second edge side 143 extend in a straight line along the first direction X. The concave side 142 is recessed from the plane where the first edge side 141 is located toward the blade side 13. Along the second direction Y, the portion between the first edge side 141 and the blade side 13 is the first edge portion 111, the portion between the concave side 142 and the blade side 13 is the cutting portion 12, and the portion between the second edge side 143 and the blade side 13 is the second edge portion 112.

[0050] The first edge side 141 is the blade back edge corresponding to the first edge portion 111, the second edge side 143 is the blade back edge corresponding to the second edge portion 112, and the concave side 142 is the blade back edge corresponding to the cutting portion 12. The concave side 142 connects the first edge side 141 and the second edge side 143. The first edge side 141 and the second edge side 143 can be located in the same straight line direction, that is, both the first edge side 141 and the second edge side 143 are parallel to the cutting edge side 13. The concave side 142 is recessed from the straight line containing the first edge side 141 and the second edge side 143 towards the cutting edge side 13, thereby forming a blade back edge extending in a "U" shape.

[0051] In this configuration, when preparing the hot cutting blade 1, a rectangular hot cutting blade 1 with a regular shape can be prepared first, and then part of the structure in the middle area of ​​the back side 14 of the rectangular hot cutting blade 1 can be removed, forming a groove facing the cutting edge side 13 on the back side 14. The blade structure retained in the groove is the cutting part 12.

[0052] Of course, in embodiments not shown in the accompanying drawings of this utility model, the first edge side 141 and the second edge side 143 may extend in any shape such as an arc, and this utility model embodiment does not limit this.

[0053] Furthermore, this embodiment of the present invention does not limit the specific shape of the concave side 142, that is, the specific shape of the groove on the back of the blade 14. Any concave shape is within the scope of the technical solution protected by this embodiment of the present invention.

[0054] For example, please refer to... Figure 3 The concave side 142 includes a first extension 1421, a second extension 1422, and a third extension 1423 connected sequentially along the extending direction of the concave side 142; the first extension 1421 connects the first edge side 141 and the second extension 1422, and the third extension 1423 connects the second extension 1422 and the second edge side 143; the second extension 1422 extends along the first direction X, and the length of the second extension 1422 along the first direction X is less than the total length of the concave side 142 along the first direction X.

[0055] As an alternative, the orthographic projection of the recess of the hot-cutting blade 1 onto the plane of the cutting assembly 10 can be trapezoidal. The blade back edge of the cutting portion 12 includes a first extension 1421, a second extension 1422, and a third extension 1423. The second extension 1422 can refer to the upper base of the trapezoidal recess, and the first extension 1421 and the second extension 1422 can refer to the two sides of the trapezoidal recess. The length of the second extension 1422 along the first direction X is the length of the upper base of the trapezoidal recess. The total length of the concave side 142 along the first direction X can be considered as the length of the lower base of the trapezoidal recess (which does not actually exist), which is also the distance between the first edge portion 111 and the second edge portion 112 along the first direction X.

[0056] In this design, the cutting section 12 may include a first section 121, a second section 122, and a third section 123 (divided by dashed lines, but actually a single integrated structure). The first section 121 is the blade structure between the cutting edge 13 and the first extension 1421; the second section 122 is the blade structure between the cutting edge 13 and the second extension 1422; and the third section 123 is the blade structure between the cutting edge 13 and the third extension 1423. The orthographic projection of the first section 121 onto the plane of the cutting assembly 10 is trapezoidal; the orthographic projection of the second section 122 onto the plane of the cutting assembly 10 is rectangular; and the orthographic projection of the third section 123 onto the plane of the cutting assembly 10 is trapezoidal.

[0057] The width of the second portion 122 in the second direction Y is less than or equal to the minimum width of the first portion 121 in the second direction Y, and less than or equal to the minimum width of the third portion 123 in the second direction Y.

[0058] In practical applications, those skilled in the art can set the width of the second portion 122 in the second direction Y according to actual needs, and this embodiment of the present invention does not limit this. For example, the width of the second portion 122 in the second direction Y is d1, and the width of the edge portion 11 of the hot-cutting blade 1 in the second direction Y is d2. d1 can be set to ≤ 0.5d2, but is not limited thereto.

[0059] Furthermore, in practical applications, those skilled in the art can also set the lengths of the first edge side 141, the second edge side 143, and the second extension 1422 in the first direction X according to actual needs. It is understood that when the lengths of the first edge side 141, the second edge side 143, and the second extension 1422 are different, the included angles between the first extension 1421 and the third extension 1423 and the second extension 1422 may be different.

[0060] Exemplarily, in some embodiments, the included angle between the first extension portion 1421 and the second extension portion 1422 can be set within the range of 110° - 160°, so as to avoid the included angle between the two being too small, which may easily cause breakage at the connection.

[0061] Optionally, Figure 4 FIG. 5 is a schematic structural diagram of another热切 blade provided by an embodiment of the present invention. Figure 5 FIG. 6 is a schematic structural diagram of yet another热切 blade provided by an embodiment of the present invention, which can be referred to Figure 4 and Figure 5 , in other exemplary embodiments, the positive projection of the concave side 142 on the plane where the cutting assembly 10 is located is arc-shaped or "V"-shaped.

[0062] Exemplarily, Figure 4 In the shown solution, the positive projection of the depression of the热切 blade 1 on the plane where the cutting assembly 10 is located can be quasi-semicircular, that is, the concave side 142 is arc-shaped. Thus, the back edge of the cutting portion 12 is relatively smooth, which can reduce the possibility of the cutting portion 12 breaking. Figure 5 In the shown solution, the positive projection of the depression of the热切 blade 1 on the plane where the cutting assembly 10 is located can be "V"-shaped, that is, when the concave side 142 is "V"-shaped. Thus, there is a region with the narrowest width in the cutting portion 12, which can make more heat generated in this region and improve the cutting effect.

[0063] Optionally, Figure 6 FIG. 7 is a schematic structural diagram of yet another热切 blade provided by an embodiment of the present invention, which can be referred to Figure 6 , in some other embodiments, the热切 blade 1 further includes a cutting edge side 13 and a back side 14 that are oppositely arranged along the second direction Y. When performing thermal cutting using the cutting assembly 10, the cutting edge side 13 faces the colloid; the cutting edge side 13 extends in a quasi-"Ji" shape, and the back side 14 extends linearly along the first direction X.

[0064] As Figure 6 shown, different from the above embodiments, in this embodiment, it can be set that the edges of the edge portion 11 and the cutting portion 朝向 the main body portion are flush, so that the back side 14 extends linearly. The edges of the edge portion 11 and the cutting portion 朝向 the main body portion are not flush, that is, the cutting edge side 13 in contact with the colloid is recessed towards the back side 14, thereby forming a cutting edge side 13 that extends in a quasi-"Ji" shape.

[0065] In this setting method, when performing cutting, the inner groove of the热切 blade 1 can surround the colloid to better perform thermal cutting on the colloid.

[0066] Among them, the specific solution for the cutting edge side 13 extending in a quasi-"Ji" shape can be designed according to the above solution of the back layer, and details will not be described here.

[0067] It should be noted that the term "热切 blade" in the original text seems to be a specific technical term in Chinese, and it may need to be accurately translated according to the actual context. Here, a rough translation is used for the purpose of translation. If there is a more accurate English term, it should be used for substitution.Optionally, in some embodiments, in the arrangement direction of the edge portion 11 and the cutting portion 12, the length of the cutting portion 12 is greater than or equal to the width of the colloid; when performing thermal cutting using the cutting assembly 10, the cutting portion 12 covers the colloid along the direction of the thermal cutting blade 1 toward the colloid.

[0068] Taking the trapezoidal shape of the blade back recess of the cutting part 12 as an example, the length of the cutting part 12 in the direction of the edge part 11 and the arrangement direction of the cutting part 12 is the length of the cutting part 12 in the first direction X. In this embodiment, the length of the cutting part 12 along the first direction X is limited to be greater than or equal to the width of the colloid. The width of the colloid refers to the width of the colloid in the direction perpendicular to its extension direction and parallel to the plane where the fixed surface is located, that is, the width directly opposite the blade side 13 when the colloid is thermally cut. By setting the length of the cutting part 12 along the first direction X to be greater than or equal to the width of the colloid, it can be ensured that the cutting part 12 covers the colloid during cutting, thus ensuring the heating effect of the colloid cut surface.

[0069] The cutting component 10 provided in this embodiment of the present invention may also include any structure known to those skilled in the art, such as an auxiliary moving component (not shown in the figure). The auxiliary moving component may be installed on the bottom surface of the main body 2. After the cutting component 10 is placed on the fixing body 30, the auxiliary fixing component contacts the fixing body 30, thereby ensuring the stability of the movement of the cutting component 10 during cutting.

[0070] Based on the same concept, this utility model also provides a photovoltaic module disassembly device. (See reference...) Figure 2 The photovoltaic module dismantling device may include a control component 40, a drive component 50, and a cutting component 10 provided in any embodiment of the present invention; wherein, the control component 40 is used to control the power supply module of the cutting component 10 to generate current, and the drive component 50 is connected to the cutting component 10 and is used to control the movement of the cutting component 10 in the gap between the photovoltaic module 20 and the fixed body 30 during thermal cutting.

[0071] The specific configuration of the control component 40 and the drive component 50 is not limited, and those skilled in the art can configure them according to actual needs. This embodiment of the utility model does not limit this.

[0072] In this embodiment of the invention, the cutting component 10 is used to thermally cut the colloid, enabling non-destructive disassembly of the photovoltaic module 20. This avoids damage to the photovoltaic module 20 and the fixing body 30, improves the reusability of the photovoltaic module 20, reduces production costs, and enhances the maintenance and replacement efficiency of the photovoltaic module 20, which is beneficial for the promotion and application of solar energy utilization technology. Furthermore, by structurally designing the hot-cutting blade 1, the heating temperature of the cutting section 12 of the hot-cutting blade 1 can be further increased, which is beneficial for the hot-cutting operation and thus improves the hot-cutting efficiency.

[0073] The photovoltaic module dismantling device provided in this embodiment of the present invention includes all the technical features and corresponding beneficial effects of the cutting component provided in any embodiment of the present invention, which will not be described in detail here.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
