DETAILED DESCRIPTION

[0019] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0020] In the present disclosure, the orientation words such as "up, down, left, right" generally refer to the orientation of the relevant components in the actual use state, unless otherwise stated. "Inner, outer" refers to the inner and outer contours of the corresponding components. In addition, when the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements, unless otherwise indicated. The terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequential and important meanings.

[0021] The photovoltaic module 4 is used to directly convert solar energy into electrical energy and is mainly applied in the field of photovoltaic. The photovoltaic module 4 generally has two types of single-glass photovoltaic module 4 and double-glass photovoltaic module 4. Taking the single-glass photovoltaic module 4 horizontally placed as an example, from bottom to top, the single-glass photovoltaic module 4 generally includes a back plate, a rubber layer 41, a cell piece 43, a rubber layer 41, and a glass 42, and a frame is enclosed on the outside to play a fixing and protection role. Taking the double-glass photovoltaic module 4 horizontally placed as an example, from bottom to top, the double-glass photovoltaic module 4 generally includes a glass 42, a rubber layer 41, a cell piece 43, a rubber layer 41, and a glass 42, and a frame is enclosed on the outside to play a fixing and protection role.

[0022] When photovoltaic module 4 reaches the end of its service life or is damaged, recycling it can reduce energy waste and consumption. When recycling photovoltaic module 4, the frame can be disassembled first for recycling. Taking a double-glass photovoltaic module 4 as an example, after the frame is disassembled and recycled, the two layers of glass 42 and the solar cells 43 need to be further recycled. Taking a single-glass photovoltaic module 4 as an example, after the frame is disassembled and recycled, one layer of glass 42, one layer of backsheet, and the solar cells 43 need to be further recycled.

[0023] Taking a double-glass photovoltaic module 4 as an example, existing glass 42 recycling equipment for photovoltaic modules 4 typically involves breaking the glass 42 on the photovoltaic module 4 for recycling. However, when recycling glass 42 from photovoltaic modules 4 of various widths, multiple glass 42 recycling devices are required, occupying space and increasing the cost of recycling glass 42 from the photovoltaic module 4. Furthermore, this glass 42 recycling method cannot guarantee the integrity of the glass 42; the recycled glass 42 fragments cannot be directly reused. The glass 42 fragments need to be chemically treated to remove the residual adhesive layer 41 before the glass 42 fragments are reassembled into glass 42. Simultaneously, glass 42 fragments remain on the adhesive layer 41, resulting in poor glass 42 recycling efficiency, requiring an additional process to remove the broken glass 42 from the adhesive layer 41.

[0024] like Figures 1 to 8 As shown, this disclosure provides a cutting device for a photovoltaic module 4, including a support plate 1, a pressure plate 2, and a cutting device 3. The support plate 1 supports and fixes the horizontally placed photovoltaic module 4. The pressure plate 2 is disposed above the support plate 1 and is used to press the photovoltaic module 4 downwards. The cutting device 3 includes a cutting line 31 disposed between the support plate 1 and the pressure plate 2. The cutting line 31 is configured to have an adjustable length in a first direction and is movable relative to the photovoltaic module 4 in a second direction to cut the adhesive layer 41 in the photovoltaic module 4. In the first direction, the supporting range of the support plate 1 and the pressing range of the pressure plate 2 are adjustable, and the first direction is orthogonal to the second direction.

[0025] Through the above technical solution, the support plate 1 supporting and fixing the photovoltaic module 4 and the pressure plate 2 pressing the photovoltaic module 4 ensure that the position of the photovoltaic module 4 does not change in the height direction. When the photovoltaic module 4 and the cutting line 31 move relative to each other in the horizontal direction and the height of the cutting line 31 corresponds to the height of the adhesive layer 41, the cutting line 31 will cut the adhesive layer 41 after contacting it, thus separating the glass 42 from the solar cell 43 and realizing the recycling of the glass 42. At the same time, in the first direction, the supporting range of the support plate 1 and the pressing range of the pressure plate 2 are adjustable. When the first direction is the width direction of the photovoltaic module 4, the support plate 1 and the pressure plate 2 can fix photovoltaic modules 4 of various widths. The length of the cutting line 31 in the width direction of the photovoltaic module 4 is adjustable, so that the cutting line 31 can cut the adhesive layer 41 on photovoltaic modules 4 of various widths. In this way, when recycling the glass 42 on the photovoltaic module 4, it is no longer necessary to prepare multiple glass 42 recycling devices, which avoids space occupation and reduces the cost of recycling the glass 42 on the photovoltaic module 4. At the same time, the wire cutting method also avoids the glass 42 breaking during recycling.

[0026] Photovoltaic module 4 is typically rectangular. In this disclosure, the first direction can refer to the width direction of photovoltaic module 4, and correspondingly, the second direction can refer to the length direction of photovoltaic module 4. In some other embodiments, the first direction can refer to the length direction of photovoltaic module 4, and correspondingly, the second direction can refer to the width direction of photovoltaic module 4. In this case, the support plate 1 and the pressure plate 2 can fix photovoltaic modules 4 of various lengths. Unless otherwise specified, this is an example where the first direction refers to the width direction of photovoltaic module 4 and the second direction refers to the length direction of photovoltaic module 4. In this disclosure, the dimensions of the support plate 1 and the pressure plate 2 can be larger in the second direction, so that photovoltaic modules 4 of various lengths can be placed on the support plate 1 and pressed tightly by the pressure plate 2.

[0027] It should be noted that the photovoltaic module 4 used in the cutting equipment at this time is not a complete photovoltaic module 4, as the frame of the photovoltaic module 4 has been disassembled. The cutting line 31 here can be movable, which means that the cutting line 31 can move along its own extension trajectory. For example, when the two ends of the cutting line 31 can be closed together, the cutting line 31 can move along its own extension trajectory. For another example, the cutting line 31 can also move back and forth along its own extension trajectory. The moving cutting line 31 can generate more friction when it comes into contact with the adhesive layer 41 to cut the adhesive layer 41.

[0028] The cutting equipment may include a base 5, and the support plate 1 includes a first plate 11 and a second plate 12 that can be spliced ​​together. In a first direction, the first plate 11 and the second plate 12 are slidably mounted on the base 5 to adjust the support range of the support plate 1. This ensures that the contact area between the first plate 11 and the second plate 12 and the photovoltaic module 4 remains unchanged, while increasing the support range of the first plate 11 and the second plate 12 in the first direction. Here, the support range refers to the coverage area of ​​the projection of the support plate 1 in the height direction.

[0029] In some embodiments, the first plate 11 may include a first substrate 13 and a plurality of first splicing plates 14 extending from the first substrate 13 in a first direction. The second plate 12 may include a second substrate 15 and a plurality of second splicing plates 16 extending from the second substrate 15 in a first direction. The first splicing plates 14 are configured to be inserted between two adjacent second splicing plates 16, and the second splicing plates 16 are configured to be inserted between two adjacent first splicing plates 14. When the end of the first splicing plate 14 abuts against the second substrate 15 and the end of the second splicing plate 16 abuts against the first substrate 13, the support range of the support plate 1 is at its minimum. When the end of the first splicing plate 14 gradually moves away from the second substrate 15 in the first direction and the end of the second splicing plate 16 gradually moves away from the first substrate 13 in the first direction, the support range of the support plate 1 gradually increases.

[0030] The first splicing plate 14 and the second splicing plate 16 can be constructed as rectangles extending along a first direction, thus allowing the first splicing plate 14 and the second splicing plate 16 to mutually limit each other and ensure the sliding direction of the first plate 11 and the second plate 12. It is important to note that during the sliding process of the first plate 11 and the second plate 12, it is necessary to avoid excessive sliding strokes to prevent the first splicing plate 14 and the second splicing plate 16 from disengaging and to ensure the stability of the photovoltaic module 4.

[0031] Reference Figure 1 and Figure 4 , Figure 1 and Figure 4 This can be understood as the front view or side view of the cutting device. Figure 1 In this configuration, the end of the first splicing plate 14 abuts against the second substrate 15, and the end of the second splicing plate 16 abuts against the first substrate 13. At this point, the support range of the support plate 1 is minimized. Figure 4 In this configuration, the end of the first splicing plate 14 is furthest from the second substrate 15 in the first direction, and the end of the second splicing plate 16 is furthest from the first substrate 13 in the first direction. At this point, the support range of the support plate 1 is maximized. (Refer to...) Figure 2 , Figure 5 and Figure 6 , Figure 2 ,Figure 5 and Figure 6 This can be understood as a top view of the support plate 1 in the cutting equipment. Figure 2 In this configuration, the end of the first splicing plate 14 abuts against the second substrate 15, and the end of the second splicing plate 16 abuts against the first substrate 13. At this point, the support range of the support plate 1 is minimized. Figure 5 and Figure 6 In this case, the end of the first splicing plate 14 is furthest from the second substrate 15 in the first direction, and the end of the second splicing plate 16 is furthest from the first substrate 13 in the first direction. At this time, the support range of the support plate 1 is the largest.

[0032] The cutting equipment may also include a lifting device 6 for driving the pressure plate 2 closer to or further away from the support plate 1. The pressure plate 2 includes a third plate 21 and a fourth plate 22 that can be spliced ​​together. In the first direction, the third plate 21 and the fourth plate 22 are slidably connected to the lifting device 6 to adjust the pressing range of the pressure plate 2. This ensures that the contact area between the third plate 21 and the fourth plate 22 and the photovoltaic module 4 remains unchanged, while increasing the support range of the third plate 21 and the fourth plate 22 in the first direction. Here, the pressing range refers to the coverage area of ​​the projection of the pressure plate 2 in the height direction. The lifting device 6 can provide the pressure plate 2 with a pressing force on the module. At the same time, by adjusting the moving distance of the telescopic rod in the lifting device 6, the magnitude of the pressing force can also be adjusted to prevent the pressure plate 2 from damaging the glass 42.

[0033] As described above, the first plate 11 and the second plate 12 are slidably disposed on the base 5, and the third plate 21 and the fourth plate 22 are slidably connected to the lifting device 6. In this disclosure, the method and structure of the sliding connection are not specifically limited; only the usage requirements of the first plate 11, the second plate 12, the third plate 21, and the fourth plate 22 need to be guaranteed. Taking the first plate 11 and the second plate 12 as examples, sliders can be provided on the surfaces of the first splicing plate 14 and the second splicing plate 16 facing the base 5, and a slide rail extending along a first direction can be provided on the base 5. The first plate 11 and the second plate 12 are slidably disposed on the base 5 through the sliders and the slide rail.

[0034] In some embodiments, the third plate 21 may include a third substrate 23 and a plurality of third splicing plates 24 extending from the third substrate 23 in a first direction, and the fourth plate 22 may include a fourth substrate 25 and a plurality of fourth splicing plates 26 extending from the fourth substrate 25 in a first direction. The third splicing plates 24 are configured to be inserted between two adjacent fourth splicing plates 26, and the fourth splicing plates 26 are configured to be inserted between two adjacent third splicing plates 24, to adjust the pressing range of the pressure plate 2. When the end of the third splicing plate 24 abuts against the fourth substrate 25 and the end of the fourth splicing plate 26 abuts against the third substrate 23, the pressing range of the pressure plate 2 is at its minimum. When the end of the third splicing plate 24 gradually moves away from the fourth substrate 25 in the first direction and the end of the fourth splicing plate 26 gradually moves away from the third substrate 23 in the first direction, the pressing range of the pressure plate 2 gradually increases.

[0035] The third and fourth splicing panels 24 and 26 can be constructed as rectangles extending along the first direction. This allows the third and fourth splicing panels 24 and 26 to mutually limit each other, ensuring the sliding direction of the third and fourth panels 21 and 22. It is important to note that during the sliding process of the third and fourth panels 21 and 22, excessive sliding strokes should be avoided to prevent the third and fourth splicing panels 24 and 26 from disengaging, thus ensuring stability when pressing the photovoltaic module 4. (Refer to...) Figure 8 ,exist Figure 8 In this case, the end of the third splicing plate 24 is furthest from the fourth substrate 25 in the first direction, and the end of the fourth splicing plate 26 is furthest from the third substrate 23 in the first direction. At this time, the pressing range of the pressure plate 2 is the largest.

[0036] The cutting device 3 may include a rotatable first winding roller 32, a second winding roller 33, and a pulley 34. The first winding roller 32 and the second winding roller 33 are disposed on one side of the photovoltaic module 4, and the pulley 34 is disposed on the other side of the photovoltaic module 4. The two ends of the cutting wire 31 are respectively wound around the first winding roller 32 and the second winding roller 33, and the pulley 34 is used to reverse the direction of rotation to adjust the length of the cutting wire 31. By changing the rotation direction of the first winding roller 32 and the second winding roller 33, the winding rollers can be used to either take in or release the wire, making the length of the cutting wire 31 adjustable. Specifically, the first winding roller 32 and the second winding roller 33 can be disposed on one side of the photovoltaic module 4 and connected to the support plate 1, for example, they can be connected to the first plate 11 mentioned above. The pulley 34 can be disposed on the other side of the photovoltaic module 4 and connected to the support plate 1, for example, it can be connected to the second plate 12 mentioned above. Thus, when the first plate 11 and the second plate 12 slide to increase the support range of the support plate 1, the first winding roller 32 and the second winding roller 33 will move away from the pulley 34, allowing the first winding roller 32 and the second winding roller 33 to unwind the wire, increasing the length of the cutting wire 31. When the first plate 11 and the second plate 12 slide to reduce the support range of the support plate 1, the first winding roller 32 and the second winding roller 33 will move closer to the pulley 34, allowing the first winding roller 32 and the second winding roller 33 to rewind the wire, shortening the length of the cutting wire 31.

[0037] The cutting line 31 may include a first segment 311 and a second segment 312. The first segment 311 is located between the pulley 34 and the first winding roller 32, and the second segment 312 is located between the pulley 34 and the second winding roller 33. The pulley 34 may be inclined in a first direction so that the first segment 311 and the second segment 312 are staggered in the height direction. Taking a double-glass photovoltaic module 4 as an example, the double-glass photovoltaic module 4 contains two pieces of glass 42 and two adhesive layers 41. When the pulley 34 is inclined in the first direction, the first segment 311 and the second segment 312 can be staggered simultaneously in both the first and height directions. Thus, in one cutting operation, the first segment 311 and the second segment 312 can simultaneously cut both adhesive layers 41. For details, please refer to... Figure 7 When recycling the glass 42 of the double-glass photovoltaic module 4, only one cutting operation is needed to separate both pieces of glass 42. The first segment 311 and the second segment 312 can be formed by two cutting lines 31 respectively, or as described above, by a single cutting line 31. When the cutting line 31 is wound around the pulley 34, it can change direction under the action of the pulley 34. One cutting line 31 can directly form the first segment 311 and the second segment 312, eliminating the need for two cutting lines 31 and reducing the cost of the cutting device 3.

[0038] The single-glass photovoltaic module 4 has a glass 42, a backsheet, and two adhesive layers 41. When the cutting device 3 of this application is applied to the single-glass photovoltaic module 4, it can be used not only for the recycling of the glass 42, but also for the recycling of the backsheet. Taking the cutting line 31 mentioned above as including a first segment 311 and a second segment 312 as an example, when the first segment 311 cuts the adhesive layer 41 between the cell 43 and the glass 42 in the single-glass photovoltaic module 4, the second segment 312 can also cut the cutting line 31 between the backsheet and the cell, so that the backsheet can also be completely removed from the photovoltaic module 4.

[0039] When the first winding roller 32 releases and retracts the wire, or when the first winding roller 32 retracts and releases the wire, the cutting wire 31 during the winding process may be interfered with by the cutting wire 31 already wound on the winding roller. The cutting wire 31 may wobble, and the wobble of the cutting wire 31 may affect the cutting trajectory. Therefore, a first guide wheel and a second guide wheel may be provided on the same side of the first winding roller 32 and the second winding roller 33, so that the cutting wire 31 is wound sequentially on the first winding roller 32, the first guide wheel, the first pulley 34, the second guide wheel, and the second winding roller 33. In this way, the cutting wire 31 can be further laid on the first guide wheel and the second guide wheel, increasing the stability of the cutting wire 31.

[0040] To allow the first segment 311 and the second segment 312 to be spaced apart in the height direction, in addition to tilting the pulley 34 as mentioned above, an annular groove can be formed on the rim of the pulley 34. This annular groove can accommodate the cutting line 31 and guide its direction. The annular surface of the groove is inclined to the end face of the pulley 34. This tilted arrangement of the annular groove, while guiding the direction of the cutting line 31, directly separates the first segment 311 and the second segment 312 in the height direction. The annular surface of the groove mentioned here refers to the surface enclosed by the annular groove.

[0041] During the cutting process, the horizontally placed photovoltaic module 4 and the cutting device 3 will move relative to each other in the second direction. This relative movement can take several forms. The first form is that the photovoltaic module 4 moves actively while the cutting device 3 remains stationary, in which case the cutting line 31 passively cuts the adhesive layer 41. The second form is that the photovoltaic module 4 remains stationary while the cutting device 3 moves actively, in which case the cutting line 31 actively cuts the adhesive layer 41. The third form is that when the pressure plate 2 is pressing the photovoltaic module 4, the pressure plate 2 moves to move the photovoltaic module 4, while the cutting device 3 remains stationary, in which case the cutting line 31 passively cuts the adhesive layer 41.

[0042] In the first movement method, in the first embodiment, a first drive roller 191 may be provided on the support plate 1. The first drive roller 191 is embedded in the support plate 1 and at least partially protrudes from the surface of the support plate 1 facing the photovoltaic module 4. The first drive roller 191 rotates to drive the photovoltaic module 4 to move. In this way, while the support plate 1 supports the photovoltaic module 4 through the first drive roller 191, it also drives the photovoltaic module 4 to move through the rotation of the first drive roller 191, so that the photovoltaic module 4 can move relative to the first winding roller 32, the second winding roller 33 and the pulley 34 in the second direction.

[0043] In the second embodiment, a second drive roller 192 may be provided on the support plate 1. A first fixing block 17 is provided on one side of the support plate 1, and a second fixing block 18 is provided on the other side. The second drive roller 192 is embedded in the first fixing block 17 and the second fixing block 18, and the second drive roller 192 at least partially protrudes from the surfaces of the first fixing block 17 and the second fixing block 18 facing the photovoltaic module 4. The second drive roller 192 rotates to drive the photovoltaic module 4 to move. In this way, the support plate 1 itself supports the photovoltaic module 4, and the fixing blocks provided on the support plate 1 are used to fix the second drive roller 192. The second drive roller 192 is provided on both sides of the photovoltaic module 4 and clamps the photovoltaic module 4. The rotation of the second drive roller 192 drives the photovoltaic module 4 to move, so that the photovoltaic module 4 can move relative to the first winding roller 32, the second winding roller 33, and the pulley 34 in a second direction. As described above, the first fixing block 17 may be fixed on the first substrate 13, and the second fixing block 18 may be fixed on the second substrate 15.

[0044] In the third embodiment, refer to Figures 1 to 5 The support plate 1 can be equipped with a first drive roller 191 and a second drive roller 192 at the same time. At this time, both the first drive roller 191 and the second drive roller 192 can rotate to drive the photovoltaic module 4 to move.

[0045] For the second movement method, the cutting device may further include a drive assembly 7. The drive assembly 7 includes a first slide rail 71, a first slider 72, a second slide rail 73, and a second slider 74. The first slide rail 71 is disposed on one side of the support plate 1. The first slider 72 is slidably disposed on the first slide rail 71. A first winding roller 32 and a second winding roller 33 are disposed on the first slider 72. The second slide rail 73 is disposed on the other side of the support plate 1. The second slider 74 is slidably disposed on the second slide rail 73. A pulley 34 is disposed on the second slider 74. (Refer to...) Figure 6The first slide rail 71 can be disposed on the first substrate 13, and the second slide rail 73 can be disposed on the second substrate 15. Thus, when the first plate 11 and the second plate 12 slide in the first direction, the two slide rails will also slide in the first direction. Furthermore, the two slide rails can extend simultaneously along the second direction. When the two sliders slide along the two slide rails in the second direction, they will drive the first winding roller 32, the second winding roller 33, and the pulley 34 to move in the second direction, allowing the cutting wire 31 to actively cut the adhesive layer 41.

[0046] For the third movement method, the cutting device may further include a third slide rail, which is positioned above the support plate 1 and extends along the second direction. The support plate 1 may be equipped with a support roller, which at least partially protrudes from the surface of the support plate 1 facing the photovoltaic module 4. When the pressure plate 2 is configured to press the photovoltaic module 4 and moves along the third slide rail, it drives the photovoltaic module 4 to move on the support plate 1. In this way, the pressing force of the pressure plate 2 drives the photovoltaic module 4 to move. While the support plate 1 supports the photovoltaic module 4 through the first drive roller 191, it also reduces the resistance of the photovoltaic module 4 during movement, making it easier for the pressure plate 2 to move the photovoltaic module 4 on the support plate 1 when pressing it and moving along the third slide rail.

[0047] The second objective of this disclosure is to provide a method of using a cutting device for a photovoltaic module 4 according to any of the above embodiments. It should be noted that, unless there is a contradiction, the order of steps S101, S102 and S103 can be interchanged. For example, step S102 can be performed before step S101.

[0048] In the method provided in this embodiment, in step S101, the dimensions of the photovoltaic module 4 to be processed in the first direction are obtained; In step S102, the curvature of the photovoltaic module 4 is obtained; In step S103, it is determined whether the glass 42 on the photovoltaic module 4 is broken; In step S104, the support range of the support plate 1 and the pressing range of the pressure plate 2 in the first direction are determined based on the size of the photovoltaic module 4 in the first direction, the curvature of the photovoltaic module 4, and whether the glass 42 on the photovoltaic module 4 is broken.

[0049] The dimensions of the photovoltaic module 4 to be processed in the first direction are used to determine the support range of the support plate 1 in the first direction, ensuring that the photovoltaic module 4 can be fully supported by the support plate 1.

[0050] The pressing range of the pressure plate 2 in the first direction needs to be determined based on the curvature and breakage of the photovoltaic module 4. When the photovoltaic module 4 is neither bent nor broken, the pressing range of the pressure plate 2 can be smaller than the size of the photovoltaic module 4 itself. In this way, when working with photovoltaic modules 4 of different widths, as long as the photovoltaic module 4 is neither bent nor broken, it is not necessary to adjust the pressing range of the pressure plate 2 every time, thus reducing the labor intensity of the operators.

[0051] When the photovoltaic module 4 has a certain degree of curvature, in order to ensure that the glass 42 is not damaged when the cutting line 31 cuts the adhesive layer 41, the photovoltaic module 4 needs to be flattened by the pressure plate 2. At this time, the pressing range of the pressure plate 2 in the first direction needs to be increased to ensure the flatness of the photovoltaic module 4. When the curvature of the photovoltaic module 4 is large, the pressure plate 2 also needs to have a larger clamping force. At this time, the pressing range of the pressure plate 2 in the first direction needs to be further increased to avoid the pressure plate 2 damaging the glass 42 due to the large clamping force.

[0052] When the glass 42 on the photovoltaic module 4 is damaged to a certain extent, in order to prevent the broken glass 42 from detaching from the photovoltaic module 4 during the cutting process, it is necessary to increase the pressing range of the pressure plate 2 in the first direction to ensure the flatness and integrity of the photovoltaic module 4. The pressing range of the pressure plate 2 needs to correspond to the degree of damage to the glass 42 on the photovoltaic module 4; the higher the degree of damage, the larger the pressing range of the pressure plate 2 needs to be.
