Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a photovoltaic material carrier and backsheet processing equipment. Background Technology

[0002] During the production of photovoltaic backsheets, a conductive layer needs to be set on one side of the backsheet, and an electrically isolated pattern structure needs to be etched on the conductive layer to avoid short circuits when the photovoltaic backsheet and the solar cells come into contact. After the pattern structure is etched, some areas in the pattern structure of the conductive layer need to be peeled off.

[0003] Currently, one approach is to first bond the conductive layer to the backsheet and then perform laser etching, followed by removing the filaments generated during etching to create an insulating channel in the conductive layer. However, because of the adhesive layer on the backsheet, the removal of filaments can be incomplete, resulting in residual debris in the insulating channel and causing a short circuit. Alternatively, another approach is to first laser-etch the conductive layer to create an insulating channel, and then bond the backsheet to the conductive layer. This method requires fixing the conductive layer first, and then sequentially performing laser etching, filament removal, and composite lamination to finally obtain the photovoltaic backsheet.

[0004] However, the conductive layer is a relatively thin metal layer with a relatively large area. Existing fixing methods make it difficult to fix the conductive layer as a whole, resulting in local warping. This leads to poor results when etching channels, which ultimately affects the quality of the photovoltaic backsheet. Utility Model Content

[0005] This utility model provides a photovoltaic material carrier and backsheet processing equipment to solve the problem of poor fixing effect in the prior art, which affects the quality of photovoltaic backsheets.

[0006] To solve the above problems, this utility model is implemented as follows:

[0007] In a first aspect, embodiments of this utility model provide a photovoltaic material carrier, comprising:

[0008] Flexible support, perforated plate and frame;

[0009] The perforated plate is disposed on the frame, and the perforated plate and the frame form a cavity; a vacuum interface is provided on the frame, and the vacuum interface is connected to an external air source, so that a negative pressure is formed in the cavity; a plurality of first air holes are provided on the flexible support part, and a plurality of second air holes are provided on the perforated plate.

[0010] The flexible support is disposed on the side of the perforated plate opposite to the cavity, and an airflow channel is formed between the first air hole and the second air hole. The first air hole is used to adsorb the conductive layer onto the flexible support.

[0011] Optionally, the number of second pores is greater than the number of first pores, and the first pores are aligned one-to-one with at least a portion of the second pores.

[0012] Optionally, the flexible support portion includes: a plurality of flexible patches; the plurality of flexible patches are spliced ​​together to form the flexible support portion.

[0013] Optionally, the flexible patch includes a plurality of interconnected strip structures, the plurality of strip structures being spaced apart and arranged in parallel; along the length direction of the strip structures, a plurality of the first air holes are arranged at equal intervals on the strip structures;

[0014] The ends of the strip structures are outwardly curved, and the spacing between adjacent strip structures matches the width of the strip structures.

[0015] Optionally, the photovoltaic material carrier further includes:

[0016] Support bar; the flexible support part has a gap inside;

[0017] The support bar is disposed in the gap.

[0018] Optionally, when the support bar is disposed in the gap, the height of the support bar is less than the height of the flexible support in the direction perpendicular to the flexible support.

[0019] The difference between the height of the support bar and the height of the flexible support part is 0.01 mm to 10 mm.

[0020] Optionally, an anti-sticking layer is provided in the area of ​​the perforated plate opposite to the cavity where the flexible support is not attached.

[0021] Optionally, along the long side of the perforated plate, multiple positioning point structures are provided at equal intervals near the long side of the perforated plate.

[0022] Optionally, the photovoltaic material carrier further includes:

[0023] A support partition is provided, which is connected to the frame and is disposed within the cavity to form a support.

[0024] Optionally, the support partition includes: multiple spacers and reinforcing ribs;

[0027] Secondly, this utility model provides a backsheet processing device, which includes a composite mechanism and the photovoltaic material carrier; the composite mechanism is used to composite the metal layer adsorbed by the photovoltaic material carrier with the backsheet having an adhesive layer.

[0028] This invention utilizes a perforated plate and a frame to form a cavity, with a flexible support attached to the side of the perforated plate facing away from the cavity. The cavity can be evacuated to maintain negative pressure, allowing suction to be generated externally through the second and first pores, thereby adsorbing and supporting the conductive layer. Because the flexible support is made of a flexible material, it ensures a tight fit between the first pore and the conductive layer without leakage, resulting in a more stable adsorption of the conductive layer onto the photovoltaic material carrier.

[0041] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0042] like Figure 1 As shown, this utility model provides a photovoltaic material carrier, which includes: a flexible support 10, a perforated plate 20, and a frame 30; the perforated plate 20 is disposed on the frame 30, and the perforated plate 20 and the frame 30 form a cavity; a vacuum interface 31 is provided on the frame 30, and the vacuum interface 31 is connected to an external air source, so that a negative pressure is formed in the cavity, as shown in the figure. Figure 2 This is a schematic diagram of the structure of a flexible support part provided by the present invention. The flexible support part 10 is provided with a plurality of first air holes 11, as shown in the figure. Figure 3 This is a schematic diagram of the structure of a perforated plate provided by the present invention. The perforated plate 20 is provided with a plurality of second air holes 21; the flexible support part 10 is provided on the side of the perforated plate 20 away from the cavity, and the position of the first air hole 11 and the second air hole 21 form an airflow channel. The first air hole 11 is used to adsorb the conductive layer onto the flexible support part 10.

[0043] In this embodiment of the utility model, the photovoltaic conductive backsheet mainly includes a backsheet body, a conductive layer, and an insulating layer. The conductive layer can be bonded to the backsheet body by an adhesive film or other bonding materials, or it can be applied to the backsheet body by printing, plating, spraying, or other methods. The conductive layer can be one or more of any conductive materials such as gold, silver, copper, and aluminum. The surface of the conductive layer can be made into different shapes, such as circles, squares, and other conventional and unconventional curves. The thickness of the conductive layer can be in the range of 0.01 to 10 mm. The insulating layer can be a composite layer of multiple insulating materials (such as an IEP film). The surface of the insulating layer can also be formed into conventional or unconventional lines, curves, and shapes such as circles and squares.

[0044] Specifically, a conductive layer with a patterned structure is set on the backsheet body. The purpose is to enable the backsheet to conduct electricity and interconnect with the electrodes on the back of the cells through the patterned structure of the conductive layer when it comes into contact with the back-contact solar cells. This eliminates the need for sequentially connecting the cells with solder ribbons to form a cell string, as in related technologies. Instead, the conductive layer of the photovoltaic backsheet achieves a unified overall connection of the electrodes of all cells. This eliminates the need for serial soldering of individual pads with a large number of solder ribbons, thus avoiding various adverse effects caused by the high-temperature molten metal of the solder ribbons, such as cell warping or microcracks.

[0045] In the process of preparing a photovoltaic backsheet in this embodiment of the invention, a pattern structure needs to be laser-etched on the surface of the conductive layer first. Then, the waste filaments generated by the pattern structure need to be removed, and then the conductive layer with the waste filaments removed is composited with the backsheet.

[0046] The conductive layer has a patterned structure formed on its surface by laser etching, and the patterned structure contains areas to be peeled off (see reference). Figure 2 In the example shown, when the conductive layer is adsorbed onto the flexible support 10, the area to be peeled off from the conductive layer overlaps with the continuous black curved lines in the flexible support 10. The waste wires in the area to be peeled off from the patterned structure of the conductive layer need to be removed subsequently to form a patterned structure that can be used for subsequent electrical connections. It should be noted that since the area to be peeled off is already in a detached or nearly detached state after the patterned structure is drawn on the conductive layer, there are several ways to peel off and remove the area: Method 1: The photovoltaic material carrier supporting the conductive layer with the patterned structure can be rotated 180° so that the side of the conductive layer facing away from the photovoltaic material carrier faces the direction of gravity, guiding the area to be peeled off based on gravity. Method 2: A force is applied to the side of the conductive layer facing away from the photovoltaic material carrier, such as by blowing air with a hairdryer, causing the area to be peeled off.

[0047] This utility model embodiment proposes a photovoltaic material carrier for supporting and adsorbing a conductive layer, so that the conductive layer can sequentially complete the above-mentioned operations. Specifically, refer to... Figure 1 The photovoltaic material carrier includes a flexible support 10, a perforated plate 20, and a frame 30. The perforated plate 20 and the frame 30 can be assembled to form a cavity, and the flexible support 10 can be attached to the side of the perforated plate 20 facing away from the cavity. The cavity can be evacuated to maintain negative pressure, so as to form a suction force on the outside through the second pore 21 and the first pore 11, thereby adsorbing and supporting the conductive layer. The vacuum interface 31 opened in the bottom plate 32 of the frame 30 can be connected to an external vacuum pumping device. During vacuuming, the perforated plate and the frame form a cavity to generate a vacuum suction force, thereby adsorbing the conductive layer. When the vacuum environment is eliminated, the vacuum suction force provided by the cavity disappears, and the conductive layer can be removed from the photovoltaic material carrier.

[0048] It should be noted that the position of the first pore 11 can be close to the area to be peeled, but not too close. Therefore, in this embodiment of the invention, the minimum distance between the edge of the first pore 11 and the edge of the area to be peeled can be set to 0.1mm to 2mm. This allows the first pore 11 to fix the periphery of the area to be peeled as much as possible during adsorption, facilitating the peeling of the area. However, the first pore 11 should not be too close to the area to be peeled. Considering the alignment error that may occur when the photovoltaic material carrier and the conductive layer are adsorbed, if it is too close, the first pore 11 may not be properly aligned and may overlap with the area to be peeled, affecting the subsequent peeling operation. Therefore, a distance range of 0.1mm to 2mm is adopted to balance the above two considerations.

[0049] Furthermore, the flexible support portion 10 can be made of a flexible material, such as silicone or flexible rubber. This ensures that the conductive layer, under the adsorption of the first pore 11, can be tightly bonded to the flexible support portion 10, thereby avoiding processing errors caused by poor local bonding of the conductive layer in subsequent engraving and waste removal processes. At the same time, due to the tight adhesion, the adsorption of the conductive layer by the first pore 11 can form a raised structure on the conductive layer. This raised structure can serve as a positioning mark for subsequent laying of the insulating film.

[0050] Optionally, the number of second pores is greater than the number of first pores, and the first pores are aligned one-to-one with at least a portion of the second pores.

[0051] In this embodiment of the invention, the number of second vents can be greater than the number of first vents, and the first vents are aligned one-to-one with at least some of the second vents. The purpose of this is to provide a sufficient number of second vents to ensure that each first vent has a corresponding second vent to match. This is because the size and structure of the conductive layer are different for different types of plates, and it is necessary to replace the flexible support with different sizes. In this way, the first vents on the flexible support with different sizes can be aligned with the corresponding second vents on the vent plate.

[0052] In summary, in this embodiment of the invention, a cavity can be formed by assembling a perforated plate and a frame, and a flexible support can be attached to the side of the perforated plate facing away from the cavity. The cavity can be evacuated to maintain negative pressure inside, so as to create suction force on the outside through the second and first pores, thereby adsorbing and supporting the conductive layer. Since the flexible support is made of a flexible material, this ensures that the first pore of the flexible support is tightly fitted with the conductive layer without leakage, making the adsorption of the conductive layer by the photovoltaic material carrier more stable.

[0053] Optionally, the flexible support 10 includes: such as Figure 4-6 Multiple flexible patches 12 are shown; the multiple flexible patches 12 are spliced ​​together to form a flexible support part 10.

[0054] Optionally, the flexible patch 12 includes multiple interconnected strip structures 121, which are spaced apart and arranged in parallel. Along the length direction X of each strip structure 121, multiple first air holes 11 are arranged at equal intervals. The ends of the strip structures 121 are outwardly arc-shaped, and the spacing between adjacent strip structures 121 matches the width of the strip structure 121. It should be noted that the shape of the strip structures depends on the patterning design of the conductive layer.

[0055] In this embodiment of the invention, the flexible support can be a modular structure, meaning it can be formed by splicing together multiple flexible patches. This modular design facilitates the replacement of individual flexible patches and makes maintenance and transportation of the flexible support easier. For example, if a certain area of ​​the flexible support is damaged, only the flexible patch corresponding to the damaged area needs to be replaced, without replacing the entire flexible support. Because individual flexible patches are small, they can be stored and transported separately, and then spliced ​​together to form the flexible support when using a carrier.

[0056] in, Figure 6 The flexible patch 12 shown can be located in the side edge regions of the flexible support portion 10. Figure 4 and Figure 5The flexible patch 12 shown can be located in the non-side edge region of the flexible support portion 10. The flexible support portions 10 are spliced ​​together so that the strip structure 121 of one flexible patch 12 can be embedded in the gap between the strip structure 121 of another adjacent flexible patch 12, thereby forming a... Figure 2 The overall flexible support 10 is shown.

[0057] Optional, refer to Figure 1 The photovoltaic material carrier also includes: support strip 40; such as Figure 7 As shown, a schematic diagram of a support bar structure is presented, in which a gap is provided inside the flexible support part 10, and the support bar 40 is disposed in the gap.

[0058] In this embodiment of the invention, the shape of the support strip 40 can match the outer contour of the strip structure 121. After multiple flexible patches 12 are spliced ​​together, gaps are formed between adjacent strip structures 12 to accommodate the support strip 40. The support strip 40 is embedded in the gaps formed after the flexible patches 12 are spliced ​​together, forming a coupling between the support strip 40 and the flexible patch 12 pattern. The support strip 40 can support waste wires and prevent them from falling into the gaps. On the other hand, the support strip 40 can prevent laser damage to the perforated plate. The support strip can also form a pattern processing path, so that when laser engraving is performed, the laser beam can move along the path formed by the support strip to engrave line patterns. Preferably, the support strip can be made of a laser-resistant metal material, so that the support strip can effectively resist laser erosion and ensure that laser processing does not damage the flexible support and the perforated plate.

[0059] It should be noted that the support bar 40 can also be designed as a split structure, that is, the support bar 40 can be composed of multiple parts, such as... Figure 8 The support bar segments 41 shown are spliced ​​together, which makes it easy to replace individual support bars and also makes it easier to maintain and transport the support bars.

[0060] Optionally, when the support bar is provided in the gap, the height of the support bar is less than the height of the flexible support in the direction perpendicular to the flexible support; the difference between the height of the support bar and the height of the flexible support is 0.01 mm to 10 mm, preferably 0.5-1 mm.

[0061] In this embodiment of the utility model, the height of the support strip is set to be less than the height of the flexible support part, and the height difference is between 0.01 and 10 mm. This ensures that after the conductive layer is laser-etched with lines, the backing adhesive can be prevented from overflowing onto the other side of the conductive layer and causing contamination during the subsequent hot-pressing composite process. The height difference between the support strip and the flexible support part can guide the overflowing adhesive to flow towards the position of the height difference.

[0062] Optionally, an anti-sticking layer is provided in the area on the side of the perforated plate away from the cavity where the flexible support is not attached.

[0063] In this embodiment of the invention, an anti-adhesive layer can be provided in the area of ​​the side of the vent plate away from the cavity where the flexible support is not attached. The anti-adhesive layer is made of an anti-adhesive material and can prevent the area of ​​the back plate that is not in contact with the conductive layer from being bonded to the vent plate, thus ensuring the normal progress of the hot-pressing composite process.

[0064] Optional, refer to Figure 3 Along the long side Y of the perforated plate 20, multiple positioning point structures 22 are provided at equal intervals near the long side of the perforated plate 20.

[0065] In this embodiment of the invention, laser marking on the conductive layer is a high-precision operation. Since the photovoltaic material carrier may have processing errors, these errors will affect the accuracy of the laser marking. Therefore, in this embodiment of the invention, multiple positioning point structures 22 are evenly spaced along the long side Y of the perforated plate 20, near the long side of the perforated plate 20. Positioning points can be set on the conductive layer at positions corresponding to the positioning point structures 22. When the photovoltaic material carrier adsorbs and carries the conductive layer, the positioning points on the conductive layer can be aligned one by one with the positioning point structures on the perforated plate. The conductive layer is designed such that when the positioning points are aligned with the positioning point structures on the perforated plate, the conductive layer and the photovoltaic material carrier are aligned, ensuring that the accuracy of the laser marking meets the requirements. Through this design, the processing errors of the photovoltaic material carrier can be compensated for, reducing the impact of these errors.

[0066] Optional, refer to Figure 1 Photovoltaic material carriers also include:

[0067] Support partition 50 is connected to frame 30 and is set in the cavity to form support.

[0068] In this embodiment of the utility model, the support partition 50 is used to provide structural strength support. By setting the support partition 50 in the cavity, the structural strength of the cavity composed of the perforated plate 20 and the frame 30 can be improved, the probability of deformation of the photovoltaic material carrier under external force can be reduced, and the operational stability of the photovoltaic material carrier can be improved.

[0069] Optional, refer to Figure 9 and Figure 10 The supporting partition 50 includes: multiple partition strips 51 and reinforcing ribs 50; the multiple partition strips 51 are arranged horizontally and vertically at intervals to form a grid honeycomb structure; the reinforcing ribs 52 are set at the intersection of the partition strips 51 and at the connection between the partition strips 51 and the frame 30.

[0070] In this embodiment of the utility model, multiple spacers 51 are arranged horizontally and vertically at intervals to form a grid honeycomb structure of support spacers 50. The honeycomb structure of support spacers 50 has strong structural strength, which can meet the structural strength of the cavity and reduce the probability of deformation of the photovoltaic material carrier under external force. In addition, the honeycomb structure is lightweight and uses less material, which can reduce the weight of the photovoltaic material carrier at a low cost, making the use of the photovoltaic material carrier more convenient.

[0071] In addition, the locations where the spacers 51 intersect and where the spacers 51 connect to the frame 30 are the most susceptible to deformation due to external forces. By placing reinforcing ribs 52 at the locations where the spacers 51 intersect and where the spacers 51 connect to the frame 30, this embodiment of the invention can improve the structural strength of these locations.

[0072] Optional, refer to Figure 10 The frame 30 includes a side frame 33 and a base plate 32. The side frame 33 is arranged around the base plate 32, and the base plate 32 has a vacuum interface 31.

[0073] In this embodiment of the utility model, the frame 33 is arranged around the base plate 32 to form a frame 30. The base plate 32 supports the back of the photovoltaic material carrier, and the frame 33 supports the sides of the photovoltaic material carrier. The vacuum interface 31 opened in the base plate 32 of the frame 30 can be connected to an external vacuum pumping device. During vacuuming, the vent plate and the frame form a cavity to generate vacuum suction, thereby adsorbing the conductive layer. When the vacuum environment is eliminated, the vacuum suction provided by the cavity disappears, and the conductive layer can be removed from the photovoltaic material carrier.

[0074] This utility model embodiment also provides a backplate processing device, the backplate processing device comprising: a composite mechanism, and as shown in the figure. Figure 11 The photovoltaic material carrier 1 shown; the composite mechanism is used to composite the metal layer adsorbed by the photovoltaic material carrier 1 with the backsheet having an adhesive layer.

[0075] In summary, in this embodiment of the invention, a cavity can be formed by assembling a perforated plate and a frame, and a flexible support can be attached to the side of the perforated plate facing away from the cavity. The cavity can be evacuated to maintain negative pressure inside, so as to create suction force on the outside through the second and first pores, thereby adsorbing and supporting the conductive layer. Since the flexible support is made of a flexible material, this ensures that the first pore of the flexible support is tightly fitted with the conductive layer without leakage, making the adsorption of the conductive layer by the photovoltaic material carrier more stable.
