Description

Technical Field

[0001] The present disclosure relates to a photovoltaic module, and in particular to a cutting device for a photovoltaic module. Background Art

[0002] Photovoltaic modules are used to convert sunlight directly into electrical energy and are mostly used in the photovoltaic field. Photovoltaic modules usually have two types: single-glass photovoltaic modules and double-glass photovoltaic modules. Single-glass photovoltaic modules include a frame, glass, module sheets, backboard and glue layer. The module sheets are set between the glass and the backboard through the glue layer, and the frame is finally set on the outside. The structure of a double-glass photovoltaic module includes two layers of glass, cells and glue layer. The cells are bonded between the two layers of glass through the glue layer, and the frame is finally set on the outside.

[0003] The production of photovoltaic modules requires a large amount of energy and raw materials, and recycling photovoltaic modules can reduce energy waste and consumption. When recycling photovoltaic modules, it is necessary to first disassemble the frame to recycle the frame, and then recycle the glass on the photovoltaic module through glass recycling equipment. In the related art, a glass recycling equipment can only recycle the glass on photovoltaic modules of one width. When recycling the glass on photovoltaic modules of multiple widths, it is necessary to prepare multiple glass recycling equipment, which takes up space and increases the cost of recycling the glass on the photovoltaic modules.

DETAILED DESCRIPTION

[0041] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0042] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, left, right" generally refer to the orientation of the relevant components in actual use. "Inside and outside" refer to the inside and outside of the corresponding component outline. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first", "second", etc. used in the present disclosure are to distinguish one element from another element and do not have order or importance.

[0043] Photovoltaic modules 4 are used to directly convert solar energy into electrical energy and are mostly used in the field of optoelectronics. Photovoltaic modules 4 are generally of two types: single-glass photovoltaic modules 4 and double-glass photovoltaic modules 4. Taking a horizontally placed single-glass photovoltaic module 4 as an example, from bottom to top, a single-glass photovoltaic module 4 generally includes a backplane, a glue layer 41, a battery cell 43, a glue layer 41 and a glass 42, and a frame is enclosed on the outside to fix and protect it. Taking a horizontally placed double-glass photovoltaic module 4 as an example, from bottom to top, a double-glass photovoltaic module 4 generally includes a glass 42, a glue layer 41, a battery cell 43, a glue layer 41 and a glass 42, and a frame is enclosed on the outside to fix and protect it.

[0044] When the photovoltaic module 4 reaches the end of its service life or is damaged, recycling the photovoltaic module 4 can reduce energy waste and consumption. When recycling the photovoltaic module 4, the frame can be disassembled first to recycle the frame. Taking the double-glass photovoltaic module 4 as an example, after the frame is disassembled and recycled, the two layers of glass 42 and the battery cell 43 need to be further recycled. Taking the single-glass photovoltaic module 4 as an example, after the frame is disassembled and recycled, the layer of glass 42, the layer of back plate and the battery cell 43 need to be further recycled.

[0045] Taking the double-glass photovoltaic module 4 as an example, in the related art, the existing glass 42 recycling equipment for photovoltaic modules 4 usually recycles the glass 42 on the photovoltaic modules 4 after breaking it. However, when recycling the glass 42 on photovoltaic modules 4 of various widths, multiple glass 42 recycling equipment needs to be prepared, which takes up space and increases the cost of recycling the glass 42 on the photovoltaic modules 4. In addition, this glass 42 recycling method cannot guarantee the integrity of the glass 42, and the recycled glass 42 debris cannot be directly reused. The glass 42 debris needs to be chemically treated to remove the residual glue layer 41, and then the glass 42 debris is resynthesized into glass 42. At the same time, glass 42 debris will remain on the glue layer 41, and the effect of glass 42 recycling is not good. An additional process is required to remove the broken glass 42 on the glue layer 41.

[0046] like Figures 1 to 8 As shown, the present disclosure provides a cutting device for a photovoltaic module 4, including a support plate 1, a pressing plate 2 and a cutting device 3. Among them, the support plate 1 is used to support and fix the photovoltaic module 4 placed horizontally. The pressing plate 2 is arranged above the support plate 1, and is used to press the photovoltaic module 4 downward. The cutting device 3 includes a cutting line 31 arranged between the support plate 1 and the pressing plate 2, and the cutting line 31 is arranged to be adjustable in length in a first direction, and can be moved relative to the photovoltaic module 4 in a second direction to cut the glue layer 41 in the photovoltaic module 4. In the first direction, the supporting range of the support plate 1 and the crimping range of the pressing plate 2 are respectively adjustable, and the first direction is orthogonal to the second direction.

[0047] Through the above technical solution, the support plate 1 that supports and fixes the photovoltaic module 4 and the pressing plate 2 that presses the photovoltaic module 4, so that the position of the photovoltaic module 4 in the height direction does not change. When the photovoltaic module 4 and the cutting line 31 move relatively in the horizontal direction and the height of the cutting line 31 corresponds to the height of the glue layer 41, the cutting line 31 will cut the glue layer 41 after contacting the glue layer 41, so that the glass 42 is separated from the battery cell 43, and the glass 42 is recovered. At the same time, in the first direction, the support range of the support plate 1 and the pressing range of the pressing plate 2 can be adjusted respectively. When the first direction is the width direction of the photovoltaic module 4, the support plate 1 and the pressing plate 2 can fix photovoltaic modules 4 of various widths, and the length of the cutting line 31 in the width direction of the photovoltaic module 4 can be adjusted, so that the cutting line 31 can cut the glue 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 equipment, 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 from being broken when recycling.

[0048] The photovoltaic assembly 4 is generally constructed in a rectangular shape. In the present disclosure, the first direction may refer to the width direction of the photovoltaic assembly 4, and correspondingly, the second direction may refer to the length direction of the photovoltaic assembly 4. In some other embodiments, the first direction may refer to the length direction of the photovoltaic assembly 4, and correspondingly, the second direction may refer to the width direction of the photovoltaic assembly 4. In this case, the support plate 1 and the pressing plate 2 can fix photovoltaic assemblies 4 of various lengths. In the absence of special instructions, it is taken as an example that the first direction refers to the width direction of the photovoltaic assembly 4 and the second direction refers to the length direction of the photovoltaic assembly 4. In the present disclosure, in the second direction, the size of the support plate 1 and the pressing plate 2 can be larger, so that photovoltaic assemblies 4 of various lengths can be placed on the support plate 1 and pressed by the pressing plate 2.

[0049] It should be noted that the photovoltaic module 4 used for the cutting device is not a complete photovoltaic module 4, and the frame of the photovoltaic module 4 has been disassembled. The cutting line 31 here can be movably set, and the movably set means that the cutting line 31 can move along its own extension track. For example, when the two ends of the cutting line 31 can be enclosed together, the cutting line 31 can always move along its own extension track. For another example, the cutting line 31 can also move back and forth along its own extension track. The moving cutting line 31 can generate more friction when it contacts the glue layer 41 to cut the glue layer 41.

[0050] The cutting device may include a base 5, and the support plate 1 includes a first plate body 11 and a second plate body 12 that can be spliced ​​with each other. In the first direction, the first plate body 11 and the second plate body 12 are respectively slidably arranged on the base 5 to adjust the support range of the support plate 1. In this way, the support range of the first plate body 11 and the second plate body 12 in the first direction is increased while ensuring that the contact area between the first plate body 11 and the second plate body 12 and the photovoltaic module 4 remains unchanged. The support range here refers to the coverage of the projection of the support plate 1 in the height direction.

[0051] In some embodiments, the first plate body 11 may include a first substrate 13 and a plurality of first splicing plates 14 extending from the first substrate 13 in the first direction. The second plate body 12 may include a second substrate 15 and a plurality of second splicing plates 16 extending from the second substrate 15 in the first direction. The first splicing plate 14 is configured to be inserted between two adjacent second splicing plates 16, and the second splicing plate 16 is 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, it indicates that the support range of the support plate 1 is the smallest. 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, it indicates that the support range of the support plate 1 is gradually increasing.

[0052] The first splicing plate 14 and the second splicing plate 16 can be constructed into a rectangle extending along the first direction, so that the first splicing plate 14 and the second splicing plate 16 can also limit each other to ensure the sliding direction of the first plate body 11 and the second plate body 12. It should be noted that during the sliding of the first plate body 11 and the second plate body 12, it is necessary to avoid the sliding stroke of the first plate body 11 and the second plate body 12 being too large to prevent the first splicing plate 14 and the second splicing plate 16 from being separated from each other, so as to ensure the stability of supporting the photovoltaic module 4.

[0053] Reference Figure 1 and Figure 4 , Figure 1 and Figure 4It can be understood as a front view or side view of the cutting device. Figure 1 In the embodiment, the end of the first splicing plate 14 abuts against the second base plate 15 and the end of the second splicing plate 16 abuts against the first base plate 13. At this time, the support range of the support plate 1 is the smallest. Figure 4 In the embodiment, the end of the first splicing plate 14 is farthest from the second substrate 15 in the first direction and the end of the second splicing plate 16 is farthest from the first substrate 13 in the first direction. At this time, the support range of the support plate 1 is the largest. Figure 2 , Figure 5 and Figure 6 , Figure 2 , Figure 5 and Figure 6 It can be understood as a top view of the support plate 1 in the cutting device. Figure 2 In the embodiment, the end of the first splicing plate 14 abuts against the second base plate 15 and the end of the second splicing plate 16 abuts against the first base plate 13. At this time, the support range of the support plate 1 is the smallest. Figure 5 and Figure 6 In the embodiment, the end of the first splicing plate 14 is farthest from the second substrate 15 in the first direction and the end of the second splicing plate 16 is farthest from the first substrate 13 in the first direction. At this time, the supporting range of the support plate 1 is the largest.

[0054] The cutting device may also include a lifting device 6 for driving the pressing plate 2 to move closer to or away from the supporting plate 1. The pressing plate 2 includes a third plate body 21 and a fourth plate body 22 that can be spliced ​​with each other. In the first direction, the third plate body 21 and the fourth plate body 22 are respectively slidably connected to the lifting device 6 to adjust the crimping range of the pressing plate 2. In this way, the contact area between the third plate body 21 and the fourth plate body 22 and the photovoltaic module 4 remains unchanged, and the support range of the third plate body 21 and the fourth plate body 22 in the first direction is increased. The clamping range here refers to the coverage range of the projection of the pressing plate 2 in the height direction. The lifting device 6 can provide a clamping force to the pressing plate 2 on the assembly. At the same time, by adjusting the moving distance of the telescopic rod in the lifting device 6, the size of the clamping force can also be adjusted to prevent the pressing plate 2 from crushing the glass 42.

[0055] As described above, the first plate body 11 and the second plate body 12 are slidably disposed on the base 5, respectively, and the third plate body 21 and the fourth plate body 22 are slidably connected to the lifting device 6, respectively. In the present disclosure, no specific limitation is made to the manner and structure of the sliding connection, and only the use requirements of the first plate body 11, the second plate body 12, the third plate body 21 and the fourth plate body 22 can be guaranteed. Taking the first plate body 11 and the second plate body 12 as an example, a slider may be disposed on the surface of the first splicing plate 14 and the second splicing plate 16 facing the base 5, and a slide rail extending along the first direction may be provided on the base 5, and the first plate body 11 and the second plate body 12 are slidably disposed on the base 5 through the slider and the slide rail.

[0056] In some embodiments, the third plate body 21 may include a third substrate 23 and a plurality of third splicing plates 24 extending from the third substrate 23 to the first direction, and the fourth plate body 22 may include a fourth substrate 25 and a plurality of fourth splicing plates 26 extending from the fourth substrate 25 to the first direction. The third splicing plate 24 is configured to be inserted between two adjacent fourth splicing plates 26, and the fourth splicing plate 26 is configured to be inserted between two adjacent third splicing plates 24, so as to adjust the pressing range of the pressing 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, it indicates that the pressing range of the pressing plate 2 is the smallest. 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, it indicates that the pressing range of the pressing plate 2 is gradually increasing.

[0057] The third splicing plate 24 and the fourth splicing plate 26 can be constructed into a rectangle extending along the first direction, so that the third splicing plate 24 and the fourth splicing plate 26 can also limit each other to ensure the sliding direction of the third plate body 21 and the fourth plate body 22. It should be noted that during the sliding of the third plate body 21 and the fourth plate body 22, it is necessary to avoid the sliding stroke of the third plate body 21 and the fourth plate body 22 being too large to prevent the third splicing plate 24 and the fourth splicing plate 26 from detaching from each other and ensure the stability when the photovoltaic module 4 is pressed. Figure 8 ,exist Figure 8 In the embodiment, the end of the third splicing plate 24 is farthest from the fourth substrate 25 in the first direction and the end of the fourth splicing plate 26 is farthest from the third substrate 23 in the first direction. At this time, the pressing range of the pressing plate 2 is the largest.

[0058] 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 arranged on one side of the photovoltaic module 4, and the pulley 34 is arranged on the other side of the photovoltaic module 4. The two ends of the cutting line 31 are respectively wound around the first winding roller 32 and the second winding roller 33 and switched by the pulley 34 to adjust the length of the cutting line 31. By changing the rotation direction of the first winding roller 32 and the second winding roller 33, the winding rollers can play the role of winding or unwinding, so that the length of the cutting line 31 can be adjusted. Specifically, the first winding roller 32 and the second winding roller 33 can be arranged 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 body 11 mentioned above, and the pulley 34 can be arranged on the other side of the photovoltaic module 4 and connected to the support plate 1, for example, they can be connected to the second plate body 12 mentioned above, so that when the first plate body 11 and the second plate body 12 slide to increase the support range of the support plate 1, the first winding roller 32 and the second winding roller 33 and the pulley 34 will move away from each other, and the first winding roller 32 and the second winding roller 33 can release the wire to increase the length of the cutting line 31. When the first plate body 11 and the second plate body 12 slide to reduce the support range of the support plate 1, the first winding roller 32 and the second winding roller 33 and the pulley 34 will move closer to each other, and the first winding roller 32 and the second winding roller 33 can reel in the wire to shorten the length of the cutting line 31.

[0059] The cutting line 31 may include a first section 311 and a second section 312, wherein the first section 311 is located between the pulley 34 and the first winding roller 32, and the second section 312 is located between the pulley 34 and the second winding roller 33. The pulley 34 may be tilted in the first direction so that the first section 311 and the second section 312 are staggered in the height direction. Taking the double-glass photovoltaic module 4 as an example, in the double-glass photovoltaic module 4, there are a total of two pieces of glass 42 and two adhesive layers 41. At the same time, when the pulley 34 is tilted in the first direction, the first section 311 and the second section 312 may be staggered in the first direction and in the height direction at the same time. In this way, in one cutting operation, the first section 311 and the second section 312 may cut the two adhesive layers 41 at the same time. For details, please refer to Figure 7 When recycling the glass 42 of the double-glass photovoltaic module 4, only one cutting operation is required to separate the two pieces of glass 42. The first section 311 and the second section 312 here can be formed by two cutting lines 31 respectively, or can be formed by one cutting line 31 as described above. When the cutting line 31 is wound around the pulley 34, it can be reversed under the action of the pulley 34. One cutting line 31 can directly form the first section 311 and the second section 312, without the need for two cutting lines 31, thereby reducing the cost of the cutting device 3.

[0060] The single-glass photovoltaic module 4 has a piece of glass 42, a backboard and two adhesive layers 41. When the cutting device 3 in the present application is applied to the single-glass photovoltaic module 4, it can not only be used to recycle the glass 42, but also to recycle the backboard. For example, the cutting line 31 mentioned above may include a first section 311 and a second section 312. When the adhesive layer 41 between the battery cell 43 and the glass 42 in the single-glass photovoltaic module 4 is cut by the first section 311, the second section 312 can also cut the cutting line 31 between the backboard and the battery, so that the backboard can also be completely removed from the photovoltaic module 4.

[0061] When the first winding roller 32 releases the wire and the first winding roller 32 reels the wire, or when the first winding roller 32 reels the wire and the first winding roller 32 releases the wire, the cutting wire 31 in the winding process may be disturbed by the cutting wire 31 that has been wound on the winding roller, and the cutting wire 31 may shake. The shaking cutting wire 31 may affect the cutting trajectory, so the first guide wheel and the second guide wheel arranged on the same side of the first winding roller 32 and the second winding roller 33 may be included, and the cutting wire 31 is wound around the first winding roller 32, the first guide wheel, the first pulley 34, the second guide wheel and the second winding roller 33 in sequence. In this way, the cutting wire 31 can be further laid on the first guide wheel and the second guide wheel to increase the stability of the cutting wire 31.

[0062] In order to space the first section 311 and the second section 312 in the height direction, in addition to the above-mentioned tilting of the pulley 34, an annular wheel groove can be provided on the rim of the pulley 34. The annular wheel groove can accommodate the cutting line 31 and guide the direction of the cutting line 31. The annular surface of the annular wheel groove is inclined to the end face of the pulley 34. In this way, the annular wheel groove is tilted. When guiding the direction of the cutting line 31, the annular wheel groove can directly space the first section 311 and the second section 312 in the height direction. The annular surface of the annular wheel groove mentioned here refers to the surface enclosed by the annular wheel groove.

[0063] During the cutting process, the horizontal photovoltaic module 4 and the cutting device 3 will move relative to each other in the second direction. There are multiple relative movement modes. The first movement mode is that the photovoltaic module 4 moves actively and the cutting device 3 is fixed. At this time, the cutting line 31 passively cuts the glue layer 41. The second movement mode is that the photovoltaic module 4 is fixed and the cutting device 3 moves actively. At this time, the cutting line 31 actively cuts the glue layer 41. The third movement mode is that when the pressing plate 2 presses the photovoltaic module 4, the pressing plate 2 moves to drive the photovoltaic module 4 to move, and the cutting device 3 is fixed. At this time, the cutting line 31 passively cuts the glue layer 41.

[0064] For the first moving mode, in the first embodiment, a first driving roller 191 may be provided on the support plate 1, the first driving 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 assembly 4, and the first driving roller 191 rotates to drive the photovoltaic assembly 4 to move. In this way, the support plate 1 supports the photovoltaic assembly 4 through the first driving roller 191, and also drives the photovoltaic assembly 4 to move through the rotation of the first driving roller 191, so that the photovoltaic assembly 4 can move in the second direction relative to the first winding roller 32, the second winding roller 33 and the pulley 34.

[0065] In the second embodiment, a second driving roller 192 may be provided on the support plate 1, a first fixed block 17 is provided on one side of the support plate 1, and a second fixed block 18 is provided on the other side, the second driving roller 192 is embedded in the first fixed block 17 and the second fixed block 18, the second driving roller 192 at least partially protrudes from the surface of the first fixed block 17 and the second fixed block 18 facing the photovoltaic assembly 4, and the second driving roller 192 rotates to drive the photovoltaic assembly 4 to move. In this way, the support plate 1 itself supports the photovoltaic assembly 4, and the fixed blocks provided on the support plate 1 are used to fix the second driving roller 192, the second driving roller 192 is provided on both sides of the photovoltaic assembly 4 and clamps the photovoltaic assembly 4, and the rotation of the second driving roller 192 drives the photovoltaic assembly 4 to move, so that the photovoltaic assembly 4 can move in the second direction relative to the first winding roller 32, the second winding roller 33 and the pulley 34. As described above, the first fixed block 17 can be fixed on the first substrate 13, and the second fixed block 18 can be fixed on the second substrate 15.

[0066] In the third embodiment, referring to Figures 1 to 5 The support plate 1 may be provided with a first driving roller 191 and a second driving roller 192 at the same time. At this time, both the first driving roller 191 and the second driving roller 192 can rotate to drive the photovoltaic assembly 4 to move.

[0067] For the second moving mode, the cutting device may further include a driving assembly 7, which includes a first slide rail 71, a first slider 72, a second slide rail 73, and a second slider 74, wherein the first slide rail 71 is arranged on one side of the support plate 1, the first slider 72 is slidably arranged on the first slide rail 71, the first winding roller 32 and the second winding roller 33 are arranged on the first slider 72, the second slide rail 73 is arranged on the other side of the support plate 1, the second slider 74 is slidably arranged on the second slide rail 73, and the pulley 34 is arranged on the second slider 74. Figure 6The first slide rail 71 can be arranged on the first substrate 13, and the second slide rail 73 can be arranged on the second substrate 15, so that when the first plate body 11 and the second plate body 12 slide in the first direction, the two slide rails will also slide in the first direction. And the two slide rails can extend along the second direction at the same time. When the two sliders slide along the second direction on the two slide rails, the first winding roller 32, the second winding roller 33 and the pulley 34 will be driven to move in the second direction, so that the cutting line 31 can actively cut the glue layer 41.

[0068] For the third moving mode, the cutting device may further include a third slide rail, which is disposed above the support plate 1 and extends along the second direction. A supporting roller may be disposed on the support plate 1, which at least partially protrudes from the surface of the support plate 1 facing the photovoltaic component 4. The pressing plate 2 is configured to press the photovoltaic component 4 and drive the photovoltaic component 4 to move on the support plate 1 when moving along the third slide rail. In this way, the pressing force of the pressing plate 2 drives the photovoltaic component 4 to move. While the support plate 1 supports the photovoltaic component 4 through the first driving roller 191, it also reduces the resistance of the photovoltaic component 4 when moving, so that when the pressing plate 2 presses the photovoltaic component 4 and moves along the third slide rail, it is easier to drive the photovoltaic component 4 to move on the support plate 1.

[0069] When the cutting device for photovoltaic modules 4 of the present application is used, the size of the photovoltaic modules 4 to be processed in the first direction can be obtained; the curvature of the photovoltaic modules 4 can be obtained; and it can be determined whether the glass 42 on the photovoltaic modules 4 is broken. According to the size of the photovoltaic modules 4 in the first direction, the curvature of the photovoltaic modules 4, and whether the glass 42 on the photovoltaic modules 4 is broken, the support range of the support plate 1 in the first direction and the crimping range of the pressing plate 2 in the first direction are determined.

[0070] The size of the photovoltaic assembly 4 to be processed in the first direction can determine the support range of the support plate 1 in the first direction, ensuring that the photovoltaic assembly 4 can be fully supported by the support plate 1 .

[0071] The crimping range of the pressing plate 2 in the first direction needs to be comprehensively judged based on the bending and breakage of the photovoltaic module 4. When the photovoltaic module 4 is not bent and not damaged, the crimping range of the pressing plate 2 can be smaller than the size of the photovoltaic module 4 itself, so that when operating on photovoltaic modules 4 of different widths, as long as the photovoltaic module 4 is not bent and not damaged, there is no need to adjust the crimping range of the pressing plate 2 every time, thereby reducing the labor intensity of the operators.

[0072] When the photovoltaic module 4 has a certain curvature, in order to ensure that the cutting line 31 does not damage the glass 42 when cutting the adhesive layer 41, the photovoltaic module 4 needs to be flattened by the pressing plate 2. At this time, it is necessary to increase the pressing range of the pressing plate 2 in the first direction to ensure the flatness of the photovoltaic module 4. When the curvature of the photovoltaic module 4 is large, the pressing plate 2 also needs a larger pressing force. At this time, it is necessary to further increase the pressing range of the pressing plate 2 in the first direction to avoid the large pressing force causing the pressing plate 2 to damage the glass 42.

[0073] When the glass 42 on the photovoltaic module 4 is damaged to a certain extent, in order to prevent the broken glass 42 from being separated from the photovoltaic module 4 during the operation of the cutting device, it is necessary to increase the crimping range of the pressing plate 2 in the first direction to ensure the flatness and integrity of the photovoltaic module 4. The crimping range of the pressing plate 2 needs to correspond to the degree of damage of the glass 42 on the photovoltaic module 4. The higher the degree of damage, the larger the crimping range of the pressing plate 2 needs to be.
