Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and more specifically to an angle trimming device for a photovoltaic component. Background Art

[0002] Solar photovoltaic modules (also called solar panels) are the core and most important part of the solar power generation system. To ensure the mechanical strength and durability of photovoltaic modules, the modules need to be laminated. Generally, the laid laminated parts are sent to the laminator, which is vacuumed, heated and pressurized to melt the adhesive film and tightly bond it to the battery, glass and backplane to form a whole. Due to the problem of assembly accuracy, there will be excess backplane and residual adhesive on the edge of the laminated module. Therefore, in the automated production process of photovoltaic modules, a process is required to trim the laminated modules and remove the excess waste on the four sides of the modules.

[0003] In the existing photovoltaic module processing technology, the edge of the photovoltaic module is usually cut by a trimming device. The existing trimming device performs cutting operations on photovoltaic modules, usually using a cutting knife to cut the edge of the photovoltaic module along one side of the photovoltaic module, and then cutting to the end of the edge. However, the existing trimming machine cannot start cutting from the corners of the module, and the residual glue at the corners of the module needs to be further processed by a corner cutter. In addition, in order to prevent the corners of the module from being overstressed and bursting, the cutting speed of the corner cutter is slower than that of the trimming machine, and the efficiency is not high. Moreover, in the current processing technology, the trimming machine and the corner cutter still cannot completely clean the residual glue problem on the frame of the module. One of the reasons is that the corner cutter blade is passivated after repeated use, and the other is that the residual glue adheres to the blade and affects the cutting of the next component, thus greatly affecting the trimming and corner cutting effect. It also requires further processing by back-end manpower, which greatly increases the production cost.

[0004] Therefore, there is an urgent need for a photovoltaic module corner trimming device that can improve the incomplete cutting phenomenon, ensure the edge and corner cutting effect, save back-end cleaning manpower and production costs, and improve the efficiency of automated cutting.

[0040] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] Please refer to Figure 1-Figure 3 , Figure 1 This is a structural schematic diagram of the angle trimming device for photovoltaic modules provided by the utility model. Figure 2 yes Figure 1 A structural schematic diagram of the angle trimming device in the photovoltaic module when trimming the angle. Figure 3 yes Figure 2 A partial enlarged structural schematic diagram of the J1 area in the middle, the photovoltaic module corner trimming device 000 provided in this embodiment includes multiple cutting components 10 and multiple cleaning components 20, the cutting components 10 are used to trim the corner 00A of the photovoltaic module 00, and the cleaning components 20 are used to clean the corner 00A of the photovoltaic module 00 (it can be understood that this embodiment does not limit the range of the corner 00A of the photovoltaic module 00. During specific implementation, the range of the corner 00A where the corner trimming device is active can be specifically defined according to the range of residual glue remaining at the corner of the photovoltaic module 00);

[0042] In the two cutting assemblies 10 arranged in pairs, for example, one cutting assembly 10A and the other cutting assembly 10B are two cutting assemblies 10 arranged in pairs, one cutting assembly 10A moves along a first direction X, and the other cutting assembly 10B moves along a second direction Y; wherein the first direction X and the second direction Y are perpendicular to each other; the two cutting assemblies 10 arranged in pairs correspond to one cleaning assembly 20;

[0043] The cutting assembly 10 includes a rotary cutter structure 101 , and the cleaning assembly 20 includes a cleaning structure 201 .

[0044] Specifically, the angle trimming device 000 for photovoltaic modules provided in this embodiment can be used to trim the laminated photovoltaic modules (such as Figure 2The photovoltaic component 00 shown in the figure is subjected to an edge trimming treatment, and after the excess waste materials on the four sides of the component are trimmed, the corner 00A of the photovoltaic component 00 (i.e., the end of each edge of the photovoltaic component 00) is further subjected to an angle trimming treatment, and the residual glue and waste materials remaining at the corner 00A of the photovoltaic component 00 are further trimmed and cleaned. Specifically, the angle trimming device 000 of the photovoltaic component of this embodiment includes a plurality of trimming components 10 and a plurality of cleaning components 20, wherein the trimming component 10 is used to trim the corner 00A of the photovoltaic component 00, trim the residual glue and waste materials at the corner 00A of the photovoltaic component 00, and the cleaning component 20 is used to clean the corner 00A of the photovoltaic component 00, and is used to clean the residual glue and waste materials cut off by the trimming component 10, so as to avoid residual impurities at the corner 00A of the photovoltaic component 00.

[0045] It can be understood that when the shape of the photovoltaic module 00 is Figure 2 In the case of the flat rectangular parallelepiped structure shown, the photovoltaic assembly 00 may include four corners 00A, then two cutting assemblies 10 and a corresponding cleaning assembly 20 arranged in pairs may be arranged at one corner 00A of the photovoltaic assembly 00, and cutting assemblies 10 and cleaning assemblies 20 may be arranged at the other three corners 00A, so as to meet the angle trimming work of the photovoltaic assembly angle trimming device 000 of this embodiment on each corner 00A of the photovoltaic assembly 00. The shape of the photovoltaic assembly 00 in this embodiment is only an example, and in specific implementation, it can be operated according to actual settings.

[0046] like Figure 2 As shown, among the multiple cutting components 10 and multiple cleaning components 20 included in the angle trimming device 000 of the photovoltaic component of this embodiment, every two cutting components 10 can be arranged in pairs, such as being arranged in pairs at a corner 00A of the photovoltaic component 00, that is, two cutting components 10 can be correspondingly arranged at a corner 00A of the photovoltaic component 00, and the two cutting components 10 arranged in pairs correspond to one cleaning component 20, that is, one cleaning component 20 can be correspondingly arranged at a corner 00A of the photovoltaic component 00.

[0047] Among the two cutting components 10 arranged in pairs, if they are named as a cutting component 10A and the other cutting component 10B, the one cutting component 10A and the other cutting component 10B are two cutting components 10 arranged in pairs, and one cutting component 10A moves along the first direction X, and is used to cut the residual glue and waste at the end of one side edge at a corner 00A of the photovoltaic component 00, and the other cutting component 10B moves along the second direction Y, and is used to cut the residual glue and waste at the end of the other side edge at the same corner 00A of the photovoltaic component 00, and the first direction X and the second direction Y are perpendicular to each other, which can be understood as the first direction X and the second direction Y are perpendicular to each other in the direction parallel to the plane where the photovoltaic component 00 is located, thereby achieving the effect of the two cutting components 10 arranged in pairs completing the cutting of the residual glue and waste remaining at a corner 00A of the photovoltaic component 00. After the cutting component 10 completes the cutting process, the remaining glue and waste materials cut off by the cutting component 10 can be cleaned up by a cleaning component 20 corresponding to the corner 00A of the photovoltaic component 00 to avoid residual impurities in the corner 00A of the photovoltaic component 00. That is, the remaining glue and waste materials splashed onto the upper surface of the corner 00A of the photovoltaic component 00 during cutting can be cleaned up, thereby improving the cleaning effect of the residual materials at each corner 00A of the photovoltaic component 00.

[0048] like Figure 3 As shown, in this embodiment, the cutting component 10 includes a rotary cutter structure 101. The rotary cutter structure 101 can be a rotating multiple blade structure. By controlling the rotation of the rotary cutter structure 101 in the cutting component 10, the side edge at the corner 00A of the photovoltaic component 00 is cut. For example, the rotary cutter structures 101 included in the two cutting components 10 arranged in pairs can be both located on the side of the corner 00A of the photovoltaic component 00, the plane where the rotary cutter structure 101 is located is perpendicular to the plane where the photovoltaic component 00 is located, and the plane where the rotary cutter structure 101 is located is parallel to the side 00C at the corner 00A of the photovoltaic component 00. Therefore, when the cutting component 10 controls the rotary cutter structure 101 included therein to rotate, the side 00C at the corner 00A of the photovoltaic component 00 can be cut. And of the two cutting assemblies 10 arranged in pairs, one cutting assembly 10A moves along the first direction X, that is, while the cutting assembly 10A moves along the first direction X, the rotary cutter structure 101A included therein can be controlled to rotate, thereby completing the cutting work of the end residual glue and waste material at one side edge of a corner 00A of the photovoltaic assembly 00, such as Figure 2As shown, a cutting component 10A moves along a first direction X, and the rotary cutter structure 101A included therein rotates synchronously to complete the cutting of a length M1 of the side surface 00C at the corner 00A of the photovoltaic component 00; another cutting component 10B moves along a second direction Y, that is, while the other cutting component 10B moves along the second direction Y, the rotary cutter structure 101B included therein can be controlled to rotate, thereby completing the cutting of the end residual glue and waste material at the other side edge of the same corner 00A of the photovoltaic component 00, as shown in FIG. Figure 2 As shown, another cutting assembly 10B moves along the second direction Y, and the rotary cutter structure 101B included therein rotates synchronously to complete the cutting of the M2 section length of the side surface 00C at the corner 00A of the photovoltaic assembly 00.

[0049] like Figure 3 As shown, the cleaning component 20 of this embodiment includes a cleaning structure 201. The cleaning structure 201 can be a cleaning sponge or other structure that can sweep away waste materials. This embodiment is not limited to this. It only needs to meet the requirement that the cleaning structure 201 can clean up the remaining glue and waste materials cut off by the cutting component 10 after the cutting component 10 completes the cutting process, thereby ensuring the cleaning effect of the residual materials at each corner 00A of the photovoltaic component 00.

[0050] Optionally, the cleaning structure 201 can be arranged above the corner 00A of the photovoltaic component 00, that is, at the corner 00A above the upper surface 00L of the photovoltaic component 00, so that when the cleaning component 20 is in operation, the residual glue and waste splashed onto the upper surface of the corner 00A of the photovoltaic component 00 during cutting can be cleaned.

[0051] It can be understood that the cutting component 10 in this embodiment includes but is not limited to the rotary cutter structure 101, and the cleaning component 20 includes but is not limited to the cleaning structure 201, and may also include other structures that can achieve the corner trimming work at the corner 00A of the photovoltaic component 00. This embodiment is not described in detail here, and the details can be understood by referring to the subsequent embodiments.

[0052] The photovoltaic module angle trimming device 000 provided in this embodiment can better complete the cutting and cleaning of the residual glue and waste materials at the corner 00A position of the photovoltaic module 00 through the two cutting components 10 and the corresponding cleaning component 20 provided in pairs. In addition, the cutting component 10 is provided to include a rotary cutter structure 101. By controlling the rotation of the rotary cutter structure 101, the side of the corner 00A position of the photovoltaic module 00 can be cut multiple times, which is conducive to improving the phenomenon of incomplete cutting in the existing design, and thus can better ensure the cutting and corner cutting effect. In addition, the cleaning component 20 is provided to include a cleaning structure 201 to clean the residual glue and waste materials splashed on the upper surface of the corner 00A of the photovoltaic module 00 during cutting, which can improve the cutting quality of the photovoltaic module 00, and the back-end process does not need to send manual labor to do the aftermath processing, so it is conducive to saving the back-end cleaning manpower and production costs, and can greatly improve the efficiency of automatic cutting.

[0053] In some optional embodiments, please refer to Figure 1-Figure 3 , Figure 4 and Figure 5 , Figure 4 yes Figure 2 and Figure 3 A magnified schematic diagram of the structure of the cutting component. Figure 5 yes Figure 4 A schematic diagram of a structure when the cutting assembly in the embodiment cuts the photovoltaic assembly. In this embodiment, the cutting assembly 10 further includes a first driving motor 102, a blade fixing disk 103, a bearing 104 and a rotating disk 105. The first driving motor 102 is connected to the rotating disk 105 through the bearing 104, and the blade fixing disk 103 is fixed on the rotating disk 105.

[0054] The rotary cutter structure 101 includes a plurality of blades 1010 . The plurality of blades 1010 surround a rotating disk 105 and are inserted into a blade fixing disk 103 .

[0055] This embodiment explains that the cutting assembly 10 may also include a first drive motor 102. The first drive motor 102 may be a rotary motor for controlling the counterclockwise or clockwise rotation of the rotary cutter structure 101. Specifically, the cutting assembly 10 also includes a blade fixing disk 103, a bearing 104 and a turntable 105. The first drive motor 102 is connected to the turntable 105 via the bearing 104. The first drive motor 102 is used to drive the bearing 104 to drive the turntable 105 to rotate. The blade fixing disk 103 is fixed on the turntable 105, and then the turntable 105 drives the blade fixing disk 103 to rotate following the rotation of the turntable 105. The rotary cutter structure 101 includes a plurality of blades 1010. The plurality of blades 1010 may be plugged into the blade fixing disk 103 around the turntable 105. Optionally, an insertion mechanism (not shown in the figure) is provided on the blade fixing disk 103, into which the plurality of blades 1010 may be inserted respectively to form a Figure 4The rotary cutter structure 101 shown. When the blade fixing disk 103 rotates under the control of the first driving motor 102, the multiple blades 1010 plugged into the blade fixing disk 103 can also rotate with it, thereby completing the cutting of the residual glue or residual material on the side 00C at the corner 00A of the photovoltaic component 00, and the rotary cutter structure 101 including multiple blades 1010 can ensure that the residual glue or residual material is completely cut, which can well improve the phenomenon of incomplete cutting, and is conducive to ensuring the edge and corner cutting effect. In addition, the multiple blades 1010 of this embodiment can be plugged into the blade fixing disk 103 around the rotating disk 105, that is, the multiple blades 1010 included in the rotary cutter structure 101 are split, thereby ensuring that the blades that are passivated or attached with residual glue can be replaced in time, which is conducive to further improving the edge and corner cutting effect of the rotary cutter structure 101.

[0056] It is understandable that the present embodiment does not limit the number of blades 1010 included in the rotary cutter structure 101. During specific implementation, the number of blades 1010 included in the rotary cutter structure 101 in each cutting assembly 10 can be set based on the best cutting effect that can be achieved in actual operation.

[0057] Optional, such as Figure 4 and Figure 6 As shown, Figure 6 yes Figure 4 A schematic diagram of a planar structure of a stacked cutting assembly (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 6 In the present embodiment, the blade 1010 includes a first blade 1010A and a second blade 1010B. The angle α formed by the first blade 1010A and the second blade 1010B is an acute angle.

[0058] This embodiment explains that the rotary cutter structure 101 includes a plurality of blades 1010 , each blade 1010 includes a first cutting edge 1010A and a second cutting edge 1010B intersecting each other, and the angle α formed by the first cutting edge 1010A and the second cutting edge 1010B is an acute angle.

[0059] Further optionally, the straight line where the first blade 1010A is located passes through the center 1050 of the turntable 105, that is, the straight line where the first blade 1010A is located can be understood as a 90-degree blade, and the angle α formed by the first blade 1010A and the second blade 1010B is 45-60 degrees, and the straight line where the second blade 1010B is located does not pass through the center 1050 of the turntable 105. The angles of the first blade 1010A and the second blade 1010B of the blade 1010 are designed to be different. When the rotary cutter structure 101 rotates counterclockwise and clockwise, the cutting angle and cutting contact area of ​​the residual glue or residual material on the side 00C at the corner 00A of the photovoltaic component 00 can be different. For example, when the cutting component 10 is performing an angle trimming operation, the rotary cutter structure 101 can be controlled to first cut along Figure 6 The blade 1010 rotates in the counterclockwise direction (the direction indicated by the arrow G1) as shown in the figure. At this time, when each blade 1010 rotates, it is mainly the first blade 1010A that contacts the residual glue or residual material on the side 00C at the corner 00A of the photovoltaic component 00. Since the straight line where the first blade 1010A is located passes through the center 1050 of the turntable 105, the equivalent cutting force during cutting is relatively large, and most of the residual glue or residual material on the side 00C at the corner 00A can be cut cleanly. Then, after the entire cutting component 10 moves to a certain position, the first drive motor 102 can control the rotary cutter structure 101 to rotate along the Figure 6 The rotary cutter structure 101 is rotated in the clockwise direction (the direction indicated by the arrow G2) to further grind the remaining fine adhesive residues, so that the cutting force of the entire rotary cutter structure 101 can be further improved by the first blade 1010A and the second blade 1010B having different rotation directions, thereby better ensuring the edge and corner cutting effects.

[0060] In some optional embodiments, please continue to refer to Figure 1-Figure 5 In this embodiment, the angle trimming device 000 of the photovoltaic component also includes a first transmission structure 301 and a second transmission structure 302. The first transmission structure 301 is connected to the first drive motor 102 included in one of the two cutting components 10A arranged in a pair, and the first transmission structure 301 controls the first drive motor 102 to move back and forth in the first direction X; the second transmission structure 302 is connected to the first drive motor 102 of the other cutting component 10B of the two cutting components 10 arranged in a pair, and the second transmission structure 302 controls the first drive motor 102 of the other cutting component 10B to move back and forth in the second direction Y.

[0061] This embodiment explains that among the two cutting assemblies 10 arranged in pairs, one cutting assembly 10A moves along the first direction X, that is, while the cutting assembly 10A moves along the first direction X, the rotary cutter structure 101A included therein can be controlled to rotate, thereby completing the cutting of the end residual glue and waste material at one side edge of a corner 00A of the photovoltaic assembly 00. Specifically, when one cutting assembly 10A moves along the first direction X and the rotary cutter structure 101A included therein rotates synchronously to complete the cutting of the M1 length of the side surface 00C at the corner 00A of the photovoltaic assembly 00, The first transmission structure 301 is connected to the first drive motor 102 included in one of the two cutting assemblies 10 arranged in a pair. The first transmission structure 301 controls the first drive motor 102 to move back and forth in the first direction X, that is, the first transmission structure 301 can not only control a cutting assembly 10A including a rotary cutter structure 101A to move along the first direction X, but also control it to move back and forth and repeatedly in the first direction X until all the excess material and residual glue on the M1 section length of the side 00C at the corner 00A of the photovoltaic assembly 00 are completely cut off. Similarly, when another cutting component 10B moves along the second direction Y, that is, when another cutting component 10B moves along the second direction Y, the rotary cutter structure 101B included therein can be controlled to rotate, thereby completing the cutting of the end residual glue and waste material at the other side edge of the same corner 00A of the photovoltaic component 00. Specifically, when another cutting component 10B moves along the second direction Y, the rotary cutter structure 101B included therein rotates synchronously to complete the cutting of the M2 length of the side surface 00C at the corner 00A of the photovoltaic component 00, which can be controlled by the second transmission structure. The second transmission structure 302 is connected to the first drive motor 102 included in the other cutting assembly 10B of the two cutting assemblies 10 arranged in pairs, and the second transmission structure 302 controls the first drive motor 102 to move back and forth in the second direction Y, that is, the second transmission structure 302 can not only control the other cutting assembly 10B including the rotary cutter structure 101B to move along the second direction Y, but also control its back and forth and repeated movement in the second direction Y until all the residual materials and residual glue on the M2 section length of the side 00C at the corner 00A of the photovoltaic assembly 00 are completely cut. The setting of the first transmission structure 301 and the second transmission structure 302 in this embodiment can not only realize the linear movement of the cutting assembly 10B including the rotary cutter structure 101, but also realize its back and forth movement on a straight line, thereby realizing more complete cutting of the residual glue and waste materials at the corner 00A of the photovoltaic assembly 00, which is conducive to ensuring the quality of the photovoltaic assembly 00.

[0062] In some optional embodiments, please refer to Figure 1-Figure 6 , Figure 7 , Figure 7 yes Figure 3A schematic diagram of the front view structure when the cleaning component is used to clean the photovoltaic component. In this embodiment, the cleaning component 20 also includes a second drive motor 202, a first connecting rod 203 and a second connecting rod 204. The first connecting rod 203 and the second connecting rod 204 are movably connected via a spherical universal joint 205. One end of the first connecting rod 203 is connected to the second drive motor 202, and the end of the second connecting rod 204 away from the spherical universal joint 205 is connected to the cleaning structure 201.

[0063] This embodiment explains that the cleaning structure 201 is arranged above the corner 00A of the photovoltaic component 00, that is, it is arranged at the corner 00A position above the upper surface 00L of the photovoltaic component 00. When the cutting component 10 completes the cutting of the residual material and residual glue, the residual glue and waste materials splashed onto the upper surface of the corner 00A of the photovoltaic component 00 during cutting can be cleaned up. Specifically, the cleaning component 20 also includes a second drive motor 202, a first connecting rod 203 and a second connecting rod 204. The second drive motor 202 is connected to the first connecting rod 203. The first connecting rod 203 and the second connecting rod 204 are movably connected through a ball joint 205. The end of the second connecting rod 204 away from the ball joint 205 is connected to the cleaning structure 201. The second drive motor 202 can be a rotating motor, which drives the first connecting rod 203 and the second connecting rod 204 to rotate within a certain horizontal range. After the cutting assembly 10 completes the cutting of the residual material and the residual glue and resets, the cleaning assembly 20 can be extended by an extending structure such as a robotic arm, and the ball joint 205 can control the bending angle between the first connecting rod 203 and the second connecting rod 204. The bending angles of the first connecting rod 203 and the second connecting rod 204 are different, and the range that the cleaning structure 201 can clean is also different. The smaller the bending angle of the first connecting rod 203 and the second connecting rod 204 is, the larger the range that the cleaning structure 201 can clean is. Figure 7 The first connecting rod 203, the ball joint 205, and the second connecting rod 204 indicated by the dotted lines are the traces of the circular movement of the cleaning structure 201 when the second drive motor 202 controls the cleaning structure 201 to clean debris in a certain range. The cleaning structure 201 can be a soft material with cleaning ability such as a cleaning sponge. After the cutting component 10 completes the cutting of the residual material and residual glue and resets it, the cleaning component 20 can be extended by an extending structure such as a robotic arm, so that the cleaning structure 201 can contact the upper surface 00L at the corner 00A of the photovoltaic component 00. The second drive motor 202 controls the cleaning structure 201 to clean the residual glue and debris in a certain range, thereby completing the cleaning work on the surface of the photovoltaic component 00.

[0064] Optionally, in the present embodiment, the first connecting rod 203 is a telescopic rod structure, or the second connecting rod 204 is a telescopic rod structure, or both the first connecting rod 203 and the second connecting rod 204 are telescopic rod structures. The first connecting rod 203 of the telescopic rod structure or the second connecting rod 20 of the telescopic rod structure can flexibly control the distance between the cleaning structure 201 and the upper surface 00L of the photovoltaic component 00. When cleaning is required, the first connecting rod 203 and / or the second connecting rod 20 can be extended so that the cleaning structure 201 can contact the upper surface 00L at the corner 00A of the photovoltaic component 00; when cleaning is not required, the first connecting rod 203 and / or the second connecting rod 20 can be shortened so that the cleaning structure 201 leaves the upper surface 00L at the corner 00A of the photovoltaic component 00. Alternatively, when the spherical universal joint 205 controls the change in the bending angle between the first connecting rod 203 and the second connecting rod 204, the length of the first connecting rod 203 and / or the second connecting rod 20 can also be flexibly controlled so that the cleaning structure 201 can contact the upper surface 00L at the corner 00A of the photovoltaic component 00 to complete the cleaning work of the residual glue debris.

[0065] In some optional embodiments, please refer to Figure 8-Figure 10 , Figure 8 This is another structural schematic diagram of the angle trimming device for photovoltaic modules provided by the utility model. Fig. 9 yes Figure 8 A structural schematic diagram of the angle trimming device in the photovoltaic module when trimming the angle. Fig.10 yes Fig. 9 A locally enlarged structural schematic diagram of the J2 area, the photovoltaic component angle trimming device 000 provided in this embodiment also includes a material connection frame 40, the two cutting components 10 arranged in pairs correspond to one material connection frame 40, and the material connection frame 40 is located on the side of the cutting component 10 away from the cleaning component 20.

[0066] This embodiment explains that the photovoltaic module angle trimming device 000 also includes a material connection frame 40, which is used to collect residual glue and waste cut by the cutting component 10. Two cutting components 10 arranged in pairs correspond to one material connection frame 40, and the material connection frame 40 can be L-shaped, that is, the two cutting components 10 arranged in pairs share one material connection frame 40, which can save equipment layout space. The material connection frame 40 is located on the side of the cutting component 10 away from the cleaning component 20. When the two cutting components 10 arranged in a pair correspond to a corner 00A of the photovoltaic component 00, the cleaning component 20 is located directly above the corner 00A, and the material connection frame 40 can be set directly below the corner 00A, and the orthographic projection of the material connection frame 40 to the plane where the photovoltaic component 00 is located needs to cover the two cutting components 10 arranged in a pair, so as to ensure that the residual glue and waste materials cut off by the rotary cutting knife structure 101 of the two cutting components 10 arranged in a pair at the corner 00A can be completely collected by the material connection frame 40 below it, so as to prevent the residual glue and waste materials from falling outside the material connection frame 40, which is beneficial to save the subsequent manual cleaning machine cleanup process.

[0067] In some optional embodiments, please refer to Figure 8 , Fig. 9 and Fig.11 , Fig.11 yes Fig. 9 Another partial enlarged structural schematic diagram of the middle J2 area, the photovoltaic component angle trimming device 000 provided in this embodiment also includes an air blowing pipe 50, the air blowing pipe 50 is located on the side of the cutting component 10 away from the material connection frame 40, and the air outlet 50L of the air blowing pipe 50 faces the material connection frame 40.

[0068] This embodiment explains that the angle trimming device 000 of the photovoltaic module can also include an air blowing pipe 50. Optionally, the air blowing pipe 50 can be formed by opening a circular hole in the top plate of the entire angle trimming device and then extending the pipe, that is, the air blowing pipe 50 is located on the side of the cutting component 10 away from the material connection frame 40, and the air outlet 50L of the air blowing pipe 50 is set to face the material connection frame 40. The air blowing pipe 50 is used to blow the cut residual glue and waste to the material connection frame 40 below when the rotary cutter structure 101 of the cutting component 10 cuts the residual glue and waste at the corner 00A. The direction of the air outlet in the air blowing pipe 50 is as follows: Fig.11 As shown by the dotted arrow K, it is possible to better prevent residual glue and waste materials from falling outside the material receiving frame 40.

[0069] Optionally, a timing mechanism may be provided to control the timing of blowing air into the air blowing duct 50. Further, optionally, the air outlet 50L of the air blowing duct 50 may be designed to be slightly larger to cover the range of a corner 00A of the photovoltaic module 00 as much as possible (not shown in the figure), so as to ensure that when two cutting assemblies 10 arranged in pairs jointly cut a corner 00A, the larger air outlet 50L of the air blowing duct 50 can completely blow the cut waste into the material receiving frame 40, and can also blow off or remove the debris remaining on the blade, which is conducive to ensuring the cutting force of the blade, and can also save the subsequent manual cleaning process of the machine and improve efficiency.

[0070] In some optional embodiments, please continue to refer to Figure 1-Figure 3 In this embodiment, the angle trimming device 000 of the photovoltaic module includes four repair units 01, each repair unit 01 includes two cutting components 10 and a cleaning component 20 arranged in pairs; specifically, taking the photovoltaic module 00 to be repaired as a flat rectangular parallelepiped as an example, the photovoltaic module 00 includes four corners 00A, then one corner 00A can correspond to one repair unit 01, that is, the number of repair units 01 included in the angle trimming device is consistent with the number of corners 00A included in the photovoltaic module 00 to be repaired, such as Figure 2 As shown. Along the first direction X, two repair units 01 are arranged opposite to each other; along the second direction Y, two repair units 01 are arranged opposite to each other, so that when the angle trimming device 000 of the photovoltaic module is repairing the residual glue and waste materials on the corner 00A of the photovoltaic module 00, multiple repair units 01 can be carried out synchronously, and the angle trimming process of all corners 00A of the photovoltaic module 00 can be completed synchronously, thereby avoiding the rotation and displacement of the photovoltaic module 00 during the angle trimming process, which is conducive to ensuring the production quality of the photovoltaic module 00, and can also improve the efficiency of the angle trimming device, thereby improving the efficiency of the entire process.

[0071] It can be seen from the above embodiments that the photovoltaic module angle trimming device provided by the utility model achieves at least the following beneficial effects:

[0072] The corner trimming device for photovoltaic modules provided by the utility model can further perform corner trimming on the corners of the photovoltaic modules after the lamination is completed by the trimming device, and after the excess waste materials on the four sides of the modules are trimmed, the residual glue and waste materials remaining at the corners of the photovoltaic modules are further trimmed, and the residual glue and waste materials remaining at the corners of the photovoltaic modules are further trimmed and cleaned. The corner trimming device for photovoltaic modules of the utility model includes a plurality of trimming components and a plurality of cleaning components, wherein the trimming components are used to trim the corners of the photovoltaic modules, trim the residual glue and waste materials at the corners of the photovoltaic modules, and the cleaning components are used to clean the corners of the photovoltaic modules, and are used to clean the residual glue and waste materials cut off by the trimming components, so as to avoid residual impurities at the corners of the photovoltaic modules. By means of two trimming components arranged in pairs and a corresponding cleaning component, the cutting and cleaning of the residual glue and waste materials at the corners of the photovoltaic modules can be better completed. In addition, a cutting assembly including a rotary cutter structure is provided. By controlling the rotation of the rotary cutter structure, the side of the corner of the photovoltaic module can be cut multiple times, which is conducive to improving the phenomenon of incomplete cutting in the existing design, and thus can better ensure the effect of cutting edges and corners. In addition, a cleaning assembly including a cleaning structure is provided to clean up the residual glue and waste materials splashed on the upper surface of the corner of the photovoltaic module during cutting, which can improve the cutting quality of the photovoltaic module. The back-end process does not need to send manual labor for post-processing, which is conducive to saving back-end cleaning manpower and production costs, and can greatly improve the efficiency of automated cutting.
