Description

[0002] With the increasing global emphasis on renewable energy, photovoltaic (PV) power plants, as a clean and renewable energy source, have received widespread attention and popularity. As the requirements for the power generation efficiency of PV modules increase, equipment manufacturers use film-applying equipment to attach reflective film strips to the backsheet of the PV module's arrangement. This adds a reflective structure to the uncovered areas of the cells, allowing light to be reflected onto adjacent cells, increasing secondary absorption of light by the cells. However, the reflective film strips are typically placed in the gaps between cell strings and cells, employing a double-layer composite film structure of metal and insulation. In practical applications, short circuits often occur in the overlapping areas of the string and cell reflective films, thus affecting the performance of the PV module.

Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] To better understand this application, the following will be combined with... Figures 1 to 9 The solutions provided in the embodiments of this application are described in detail.

[0034] Figure 1 The diagram shown is a structural schematic of a cutting device provided in an embodiment of this application. Figure 2a The diagram shown is a schematic diagram of the overlapping area between the serial reflective film and the sheet reflective film provided in an embodiment of this application.

[0035] Figure 2b The diagram shown is a schematic representation of the overlapping area between the serial reflective film and the sheet reflective film according to another embodiment of this application. Figure 1 , Figures 2a to 2cAs shown, a cutting device provided in one embodiment of this application is configured to cut the overlapping area 203 between the string reflective film and the sheet reflective film. The cutting device 100 includes: a support platform 101, a cutting device 102, and a driving device 105. Specifically, the support platform 101 is configured to support the battery sheet 200, on which the string reflective film 201 and the sheet reflective film 202 are attached. The string reflective film 201 includes a first metal layer 2011, and the sheet reflective film 202 includes a second metal layer 2021. The cutting device 102 includes one or more cutting components 1021 and is disposed above the support platform 101; the driving device 105 is mounted to the support platform 101 (e.g., ...). Figure 1 (as shown); or installed to the cutting device 102, such that the cutting assembly 1021 moves relative to the support table 101, and is configured to drive the cutting device 102 to disconnect the first metal layer 2011 or the second metal layer 2021 of the overlapping area 203.

[0036] For example, one or more cutting components 1021 can perform cutting simultaneously or separately. When a portion of the battery sheet is defective, the defective portion needs to be replaced. In the replaced battery sheet, only the overlapping area of ​​the sheet reflective film and the string reflective film required for replacement needs to be cut. When there are multiple cutting components 1021, each cutting component 1021 can perform cutting, thereby cutting the replacement portion. In practical applications, the cutting component 1021 can also cut battery sheets 200 with different film-coating distances.

[0037] Normally, the overlap area between the series reflective film 201 and the sheet reflective film 202 causes a short circuit in the solar cell as follows: Figure 2a and Figure 2b The two scenarios are shown. For example... Figure 2a As shown, the overlapping area 203 of the sheet reflective film 202 and the series reflective film 201 is the middle part of the series reflective film 201. The presence of metal burrs causes the middle part of the first metal layer 2011 to contact the metal layer of the second metal layer 2021, thereby causing a short circuit. Therefore, the cutting device provided in this application cuts this contact part, that is, cuts the second metal layer 2021, so that the second metal layer 2021 of the contact part is cut off, thus avoiding the occurrence of short circuit from a physical structure perspective. Or, as Figure 2b As shown, the overlapping area 203 of the sheet reflective film 202 and the series reflective film 201 is located at the edge region of the series reflective film strip 201. Therefore, the cutting equipment provided in this application cuts this contact portion, that is, cuts the first metal layer 2011, thereby achieving the purpose of avoiding short circuits. It should be understood that... Figure 2aThe overlapping area of ​​the sheet reflective film strip 202 and the string reflective film strip 201 is located in the middle of the first metal layer 2011. In actual applications, the overlapping area 203 may be located in any area or edge area of ​​the non-edge area of ​​the first metal layer 2011. The cutting device 100 provided in this application embodiment can cut different overlapping areas 203 according to requirements. Figure 2c The diagram shown is a structural schematic of a battery sheet provided in one embodiment. Figure 2c It is known that the overlapping areas of the serial reflective film and the sheet reflective film of the battery sheet can be located in different areas of the battery sheet. The cutting equipment provided in this application embodiment can achieve cutting at different positions.

[0038] The cutting device provided in this application embodiment achieves the purpose of cutting the overlapping area between the serial reflective film and the sheet reflective film through the cutting device, thereby avoiding contact between the serial reflective film strip and the sheet reflective film strip in terms of physical structure and solving the short circuit problem.

[0039] Figure 3 The diagram shown is a structural schematic of a cutting device provided in one embodiment of this application. Figure 3 As shown, the cutting device 102 further includes: a horizontal support assembly 1022, extending along a first horizontal direction (e.g., Figure 3 (as shown in the X direction), the first horizontal direction is parallel to the film application direction of the reflective film or the film application direction of the sheet reflective film; one or more cutting components 1021 are installed to the horizontal support component 1022 along the first horizontal direction, and each cutting component 1021 is movably connected to the horizontal support component 1022, so that the cutting component 1021 corresponds to the overlapping area 203.

[0040] For example, the horizontal support component 1022 can be a profile to provide support for the cutting component 1021, and each cutting component 1021 is movably connected to the horizontal support component 1022, such that the cutting component 1021 corresponds to the overlapping area 203. By the displacement between the cutting component 1021 and the horizontal support component 1022, the cutting component 1021 can cut a certain film strip or cut the battery cells 200 with different film-attaching distances.

[0041] The cutting device of the cutting equipment provided in this application embodiment realizes the relative movement of the cutting component 1021 relative to the battery sheet 200 through the horizontal support component 1022, thereby realizing the automatic displacement of the cutting component 1021 and simplifying the complexity of the cutting operation.

[0042] In some embodiments, such as Figure 1As shown, the cutting device also includes a detection element 103 and a controller 104. The detection element 103 is equipped with the cutting device 102 and is configured to obtain the position of the overlapping area 203. The detection element 103 and the cutting component 1021 are both electrically connected to the controller 104. The controller 104 drives the cutting component 1021 to correspond with the overlapping area 203 based on the position of the overlapping area 203. Figure 1 The detection element 103 shown is installed on the cutting device. It should be understood that the detection element 103 can be installed on the support table 101, or it can be installed on both the cutting device 102 and the support table 101.

[0043] For example, the detection element 103 can be a camera, which acquires image information of the overlapping area 203 and performs recognition to obtain the position information of the overlapping area 203. Since the detection element 103 is electrically connected to the controller 104, the controller 104 can obtain the position information of the overlapping area 203 and control the displacement of the cutting component 1021 to automatically move the cutting component 1021 to the overlapping area 203.

[0044] For example, the detection element 103 can also be other detection devices, such as laser scanning devices. It should be understood that the detection element 103 only needs to be able to achieve the function of obtaining the position information of the overlapping area 203. The specific type of the detection element 103 is not further limited in this application embodiment.

[0045] The embodiments of this application can locate the overlapping area through the detection component, and in conjunction with the controller and cutting component, can achieve precise cutting of the overlapping area, further improving the cutting accuracy.

[0046] Figure 4 As shown Figure 1 The diagram shows an enlarged view of the cutting equipment at point A. Figure 4 As shown, the drive unit 105 includes a component conveying assembly 1051, which is configured to convey the battery sheet 200; combined with Figure 3 As shown, the cutting device 102 is connected to the support platform 101, and the arrangement direction of the two or more cutting components 1021 is (e.g., Figure 3 The X direction shown is perpendicular to the conveying direction of the conveying component 1051; or, the driving device 105 includes a driver (not shown), the cutting device 102 is movably connected to the support table 101 via the driver, and the arrangement direction of the two or more cutting components 1021 is perpendicular to the moving direction of the cutting device 102 (e.g., the X direction shown is perpendicular to the conveying direction of the conveying component 1051); or, the driving device 105 includes a driver (not shown), the cutting device 102 is movably connected to the support table 101 via the driver, and the cutting device 102 is movably connected to the support table 101, and the arrangement direction of the two or more cutting components 1021 is perpendicular to the moving direction of the cutting device 102 (e.g., the X direction shown is perpendicular to the conveying direction of the conveying component 1051); Figure 1 The Y direction shown) is vertical.

[0047] For example, the conveying component 1051 includes a conveyor belt, which conveys the battery sheet 200. In practical applications, the conveying component 1051 can adopt other forms, such as roller conveying, chain conveying, etc., as long as the effect of conveying the battery sheet 200 can be achieved.

[0048] The cutting equipment provided in this application embodiment conveys battery sheets through a conveying component, thereby enabling batch processing of battery sheets and reducing the complexity of the processing technology.

[0049] In some embodiments, the cutting assembly 1021 includes one or more of a laser cutting unit, a cutter, and a resistance wire. The cutting assembly provided in this application simplifies the processing technology of the cutting equipment by employing one or more of a laser cutting unit, a cutter, and a resistance wire, while meeting the needs of different application scenarios.

[0050] Figure 5 The diagram shows the connection between the first vertical adjustment component and the cutting component. Figure 5 As shown, in some embodiments, the cutting device 102 further includes: one or more first vertical adjustment components 1023, mounted to the cutting component 1021, each first vertical adjustment component 1023 being connected to one or more cutting components 1021 and configured to drive the cutting component 1021 to move closer to or away from the overlapping area in a vertical direction.

[0051] For example, the first vertical adjustment component 1023 is a motor or other driving device. When there is one first vertical adjustment component 1023, it can simultaneously drive multiple cutting components 1021 to move closer to or further away from the overlapping area in the vertical direction, or drive each cutting component 1021 to move closer to or further away from the overlapping area in the vertical direction. When there are multiple first vertical adjustment components 1023, corresponding to the number of driving cutting components 1021, each first vertical adjustment component 1023 is connected to each driving cutting component 1021, thereby driving each cutting component 1021 separately. It should be understood that when there are multiple first vertical adjustment components 1023, which are fewer than the number of driving cutting components 1021, one first vertical adjustment component 1023 can drive multiple cutting components 1021 individually or simultaneously.

[0052] For example, the first vertical adjustment component 1023 can drive the cutting component 1021 to move vertically in the vertical direction. The cutting depth can be adjusted according to the needs to ensure the cutting effect of the metal layer in the overlapping area between the serial reflective film and the sheet reflective film. This ensures the physical structure of the metal layer in the overlapping area between the serial reflective film and the sheet reflective film is broken, avoiding short circuits caused by contact between the metal layers in the overlapping area between the serial reflective film and the sheet reflective film.

[0053] The cutting device provided in this application embodiment enables the cutting component to move closer to or further away from the overlapping area in the vertical direction through the first vertical adjustment component, thereby realizing automatic adjustment of the distance between the cutting component and the overlapping area in the vertical direction, further ensuring the cutting accuracy and simplifying the complexity of the cutting operation.

[0054] Figure 6a The diagram shown is a structural schematic of the second vertical adjustment component provided in an embodiment of this application. Figure 6b The image shown is an exploded view of a second vertical adjustment assembly provided in an embodiment of this application. Figure 6a and Figure 6b As shown, the cutting device 102 further includes: one or more second vertical adjustment components 1024, installed to the horizontal support component 1022, each second vertical adjustment component 1024 being connected to a cutting component 1021; each second vertical adjustment component 1024 includes a support component 10241 and a vertical adjustment plate 10242, the support component 10241 being slidably connected to the horizontal support component 1022 along a first horizontal direction; the vertical adjustment plate 10242 and the support component 10241 being arranged adjacent to each other in a second horizontal direction, the vertical adjustment plate 10242 having an elongated hole 102421 extending in a vertical direction, the second horizontal direction being perpendicular to the first horizontal direction; and a locking component 10243 passing through the elongated hole 102421 and being detachably connected to the support component 10241, so that the support component 10241 can move relative to the vertical adjustment plate 10242 in a vertical direction and can be fixed by the locking component 10243.

[0055] For example, the second vertical adjustment assembly 1024 includes components that mate with the vertical adjustment plate 10242. Specifically, the vertical adjustment plate 10242 can extend in a vertical direction and has an elongated hole 102421 extending in a vertical direction; a first fixing member mates with the vertical adjustment plate and is connected to the supporting assembly 10241, and is disposed below the vertical adjustment plate 10242. The first fixing member has a first threaded portion that extends through the first fixing member in a vertical direction; a first threaded member is threaded to the first threaded portion and abuts against the lower end of the vertical adjustment plate 10242, wherein the first threaded member is capable of moving upward in a vertical direction to push the vertical adjustment plate upward in a vertical direction.

[0056] For example, the first threaded member includes a bolt, stud, or threaded rod, etc. It should be understood that in order to enable the first threaded member to move upward in a vertical direction, the first threaded member may also include necessary components, such as nuts, washers, or other components.

[0057] For example, to improve the pushing effect on the vertical adjustment plate 10242, the first fixing member can correspond to the size of the vertical adjustment plate. For instance, the length direction of the first fixing member is parallel to the width direction of the vertical adjustment plate, and the length of the first fixing member is equal to the width of the vertical adjustment plate. Furthermore, the first threaded portion can be located at both ends of the first fixing member, so that the position abutting against the lower end of the vertical adjustment plate 10242 is located at both ends of the vertical adjustment plate 10242, thereby ensuring that the vertical adjustment plate 10242 can be subjected to uniform force and ensuring the stability of the vertical adjustment plate 10242's movement in the vertical direction.

[0058] For example, the first screw connector can be driven to move upward in the vertical direction by the power component, and the distance of the first screw connector moving upward in the vertical direction can be precisely controlled, thereby achieving precise displacement of the cutting component in the vertical direction.

[0059] For example, the cooperation between the vertical adjustment plate 10242 and the first screw connector enables the vertical adjustment plate 10242 to move in the vertical direction, and the cooperation with the power component enables the first screw connector to move upward in the vertical direction with precise position control, thereby ensuring the accuracy of the vertical displacement of the cutting assembly.

[0060] For example, the vertical adjustment plate 10242 has an elongated hole 102421 extending in the vertical direction. The locking assembly 10243 passes through the elongated hole 102421 and is detachably connected to the supporting assembly 10241. Therefore, the vertical adjustment plate 10242 moves vertically within the range of the elongated hole 102421, achieving movement in the vertical direction. The second vertical adjustment assembly 1024 is connected to the cutting assembly 1021. Therefore, the vertical adjustment assembly 1024 can drive the cutting assembly 1021 to move vertically in the vertical direction. In practical applications, the second vertical adjustment assembly 1024 and the cutting assembly 1021 can be detachably connected.

[0061] For example, in this embodiment, the locking component 10243 is detachably connected to the supporting component 10241, and each second vertical adjustment component 1024 is detachably connected to a cutting component 1021. The detachable connection can be achieved using screws and nuts. In practical applications, the detachable connection method can be selected according to requirements, such as a pin connection. This embodiment does not further limit the specific detachable connection structure.

[0062] The cutting device provided in this application embodiment achieves precise vertical movement of the cutting component through the cooperation of the second vertical adjustment component, the support component, and the locking component, thereby further improving cutting accuracy. Furthermore, the structure for moving the cutting component vertically using the cutting device provided in this application embodiment is simpler and easier to install, thus adapting to more application scenarios.

[0063] In some embodiments, the vertical adjustment plate 10242 further includes a second threaded portion extending through the vertical adjustment plate 10242 in a second horizontal direction. The cutting device 100 further includes a second screw connector screwed to the second threaded portion and abutting against the support assembly 10241, wherein the length of one end of the second screw connector near the support assembly 10241 extending beyond the side of the vertical adjustment plate 10242 near the support assembly 10241 can define the distance between the vertical adjustment plate 10242 and the support assembly 10241.

[0064] For example, the second screw connector can be selected based on the positional spacing requirements between the vertical adjustment plate 10242 and the support assembly 10241, and the screw connector can be selected to meet the length requirements. The length of the end of the second screw connector near the support assembly 10241 extending beyond the side of the vertical adjustment plate 10242 near the support assembly 10241 can limit the distance between the vertical adjustment plate 10242 and the support assembly 10241. Since the distance between the vertical adjustment plate 10242 and the support assembly 10241 may be relatively close, the range of the distance limit between the vertical adjustment plate 10242 and the support assembly 10241 may be small. According to actual needs, the range of the distance limit between the vertical adjustment plate 10242 and the support assembly 10241 is small. It can be used to adjust the position of the battery sheet 200 in the arrangement direction of two or more cutting assemblies 1021 or the moving direction of the cutting device 102 to meet the cutting of the overlapping area 203 and ensure the cutting effect of the overlapping area 203.

[0065] In this embodiment, the distance between the vertical adjustment plate and the supporting component is limited by the second screw connector, thereby realizing the position adjustment of the cutting component in the second horizontal direction, so as to ensure the alignment of the cutting position and the cutting effect.

[0066] Figure 7 The diagram shown is a structural schematic of a horizontal support component provided in an embodiment of this application. Figure 7 As shown, the horizontal support assembly 1022 includes a support rod 10221 and a slide rail 10222. The support rod 10221 extends along a first horizontal direction; the slide rail 10222 is connected to the support rod 10221 and extends along the first horizontal direction. The support assembly 10241 is slidably connected to the slide rail 10222 along the first horizontal direction; combined with... Figure 3 As shown, there are two horizontal support components 1022, which are spaced apart in the vertical direction. The two horizontal support components 1022 are slidably connected to the second vertical adjustment component 1024 in the first horizontal direction.

[0067] In this embodiment, the slide rail and the support assembly are slidably connected along the first horizontal direction, and in conjunction with the support rod, the stability of the support assembly's movement along the first horizontal direction is ensured. Furthermore, the cutting device provided in this embodiment has two horizontal support assemblies. By having two horizontal support assemblies spaced apart in the vertical direction, the stability of the support assembly is ensured, thereby guaranteeing the stability of the cutting device.

[0068] Figure 8 As shown Figure 3 The diagram shows an enlarged view of the cutting device at point B. Figure 9 As shown Figure 8 A sectional view of the structure shown. (e.g.) Figure 8 and Figure 9 As shown, the cutting device 102 further includes: a fixing member 1025 connected to the support assembly 10241, the fixing member 1025 having a first horizontal direction (e.g., Figure 1 A groove 10251 extending in the Y direction (as shown) is formed. A portion of a slide rail 10222 near the fixing member 1025 extends into the groove 10251, allowing the fixing member 1025 to slide relative to the slide rail 10222. The fixing member 1025 has a threaded portion 10252 extending in the vertical direction, which connects the groove 10251 to the outside. A first clamping block 1026 is disposed between the top wall of the groove 10251 and the slide rail 10222. A second clamping block 1027 is disposed between the bottom wall of the groove 10251 and the slide rail 10222. A screw connector 1028 is screwed to the threaded portion 10252 and abuts against the side of the first clamping block 1026 away from the slide rail 10222 or against the side of the second clamping block 1027 away from the slide rail 10222, so that the first clamping block 1026 and the second clamping block 1027 clamp the slide rail.

[0069] For example, the fastener 1025, the first clamping block 1026, the second clamping block 1027 and the screw connector 1028 can be used together to form a clamping component, which is processed using standard parts to reduce the processing difficulty.

[0070] The cutting device provided in this application embodiment clamps the slide rail with a first clamping block and a second clamping block, thereby achieving the purpose of fixing the fixing member on the slide rail, and thus fixing the supporting component connected to the fixing member on the slide rail, so as to facilitate the cutting component to perform cutting work.

[0071] In some embodiments, such as Figure 7As shown, the cutting device 102 further includes: a measuring rod 1029, which is connected to the horizontal support assembly 1022 and extends along a first horizontal direction. The measuring rod 1029 has a scale and is configured to measure the position of the cutting assembly 1021 relative to the horizontal support assembly 1022 in the first horizontal direction; and an auxiliary measuring member 10210, which is connected to the second vertical adjustment assembly 1024 and extends to the upper surface of the measuring rod 1029. The auxiliary measuring member 10210 is configured to assist in determining the position of the cutting assembly 1021 relative to the horizontal support assembly 1022 in the first horizontal direction.

[0072] For example, in practical applications, the slide rail 10222 and the measuring rod 1029 can be arranged vertically at intervals. The slide rail 10222 and the measuring rod 1029 have the same length or the measuring rod 1029 has a longer length than the slide rail 10222. This ensures that the movement range of the support component 10241 when it moves in the first horizontal direction is within the measurement range of the measuring rod 1029, thereby improving the measurement accuracy of the measuring rod 1029 in measuring the position of the support component 10241 relative to the horizontal support component 1022 in the first horizontal direction.

[0073] For example, the auxiliary measuring component 10210 may be a reading plate that extends to the upper surface of the measuring rod 1029 to assist in determining the position of the cutting component 1021 relative to the horizontal support component 1022 in a first horizontal direction.

[0074] The cutting device provided in this application embodiment, by setting a measuring rod 1029, realizes the position of the cutting component relative to the horizontal support component in the first horizontal direction, thereby determining the relative position of the cutting component, ensuring the accuracy of the cutting position, and improving the cutting effect. Furthermore, the cutting device provided in this application embodiment, by setting an auxiliary measuring component, assists in determining the position of the cutting component relative to the horizontal support component in the first horizontal direction, which can more accurately determine the position of the cutting component relative to the horizontal support component in the first horizontal direction, further ensuring the accuracy of the cutting position positioning, thereby guaranteeing the cutting effect.

[0075] Figure 10 The diagram shown is a structural schematic of a cutting assembly provided in one embodiment of this application. Figure 9 As shown, the cutting assembly 1021 includes: a laser 10211 configured to emit a laser beam; and a focusing lens assembly 10212 detachably connected to the cutting device 102 and electrically connected to the laser 10211. The focusing lens assembly 10212 is configured to receive the laser beam and focus the laser beam onto the overlapping region 203 to cut the first metal layer 2011 or the second metal layer 2021.

[0076] For example, the focusing lens assembly 10212 includes a focusing lens and a focusing lens mounting base. The focusing lens mounting base can precisely fix and adjust the position of the focusing lens, and can be selected and customized according to different needs and application scenarios. The type of focusing lens can be selected according to needs, such as spherical lenses, aspherical lenses, cylindrical lenses, Powell lenses, axial tapered lenses, etc.

[0077] Specifically, the focusing lens assembly 10212 may include: a first clamping block, a second clamping block, and a focusing lens. Specifically, the first clamping block is detachably connected to the vertical adjustment assembly; the second clamping block is disposed opposite to the first clamping block in a second horizontal direction and is detachably connected to the first clamping block, and there is a receiving space between the first clamping block and the second clamping block; the focusing lens is disposed in the receiving space so that the first clamping block and the second clamping block clamp the focusing lens, and the focusing lens is configured to receive the laser beam and focus the laser beam onto the overlapping area to cut off the first metal layer 2011 or the second metal layer 2021.

[0078] For example, as required, in order to facilitate the installation of the focusing lens, the focusing lens assembly 10212 may include a focusing lens mount corresponding to the focusing lens, the focusing lens mount being located within a receiving space.

[0079] For example, the first clamping block and the second clamping block can together form a separate guide support. Using a separate guide support can save machining time and reduce the machining difficulty of the focusing lens assembly. In practical applications, the first clamping block and the second clamping block can be machined separately according to requirements to adapt to different focusing lens size requirements.

[0080] The cutting assembly of this application embodiment, through the cooperation of a laser and a focusing lens assembly, can achieve high-precision and high-efficiency cutting, thereby improving the accuracy of the cutting equipment.
