Description

Alignment fixtures for processing photovoltaic modules Technical Field

[0001] This utility model relates to the field of photovoltaic module production equipment technology, and in particular to an alignment tooling for processing photovoltaic modules during the photovoltaic module lamination process. Background Technology

[0002] A photovoltaic module includes a panel, an interlayer, and a backsheet. The interlayer comprises a first encapsulant film, solar cells, and a second encapsulant film. During the alignment of the photovoltaic module, multiple limiting blocks (such as limiting posts) push / press the edges of the photovoltaic module to complete the alignment of the panel and backsheet.

[0003] Because the first / second layer of adhesive film is heat-shrinkable, a 3-4 cm gap needs to be reserved at the edge of the photovoltaic module before lamination to prevent gaps caused by shrinkage after lamination heating. During operation, the panel is below, the backsheet is above, and the adhesive film is located between the panel and the backsheet. At the edges of the panel and backsheet, the reserved adhesive film will bend and adhere to the side of the panel. Therefore, this reserved portion of the adhesive film will contact the limiting block during alignment. That is, the limiting block cannot adhere to the backsheet, but rather adheres to the reserved adhesive film. In this state, a gap of 1.4 mm to 2.6 mm (the thickness of the intermediate layer) is created between the limiting block and the edge of the backsheet, resulting in a horizontal misalignment space of 1.4 mm to 2.6 mm between the panel and the backsheet, which may lead to misalignment of the panel and the backsheet.

[0004] When using existing alignment devices, photovoltaic modules frequently experience misalignment issues. Misalignment between the panel and backsheet can lead to a decrease in yield for subsequent steps such as sealing with water-blocking tape and framing, thus affecting the quality of the modules. Summary of the Invention

[0005] To address at least the above-mentioned technical problems in the existing technology, this utility model provides an alignment tooling for processing photovoltaic modules.

[0006] This utility model provides an alignment fixture for processing photovoltaic modules, including a fixture body. The fixture body includes a worktable and a limiting block. The worktable has a placement position for placing the laminate in the photovoltaic module. The limiting block is located at the side end of the worktable. The side end of the limiting block includes an adjustment position with a protruding structure. The side end of the limiting block is used to abut against the adhesive film layer extending from the laminate. The protruding structure is used to abut against the side of one of the panels of the laminate to align the first panel with the second panel.

[0007] In some embodiments, the protrusion structure is one of the following: ring structure, rectangle, semicircle, trapezoid.

[0008] In some embodiments, the protruding structure is detachably connected to the adjustment position.

[0009] In some embodiments, the protrusion structure includes at least one layer of stacked structure, the stacked structure being disposed along the protrusion direction of the protrusion structure; the number of stacked structures is used to adjust the protrusion size of the protrusion structure.

[0010] In some embodiments, the superimposed structure includes adhesive tape.

[0011] In some embodiments, the protrusion structure includes a detachably connected first substructure and a second substructure, the first substructure and the second substructure being configured to form an annular structure whose shape adapts to the limiting stop when assembled.

[0012] In some embodiments, the protrusion structure further includes a locking structure; one end of the first substructure and the second substructure are rotatably connected, and the other end is connected through the locking structure.

[0013] In some embodiments, the protrusion structure is an annular structure, and the protrusion structure includes a plurality of abutment surfaces along the circumferential direction for abutting against the panel; the plurality of abutment surfaces are at different straight-line distances from the center line of the limiting block.

[0014] In some embodiments, along the circumference of the protrusion structure, the straight-line distance between the plurality of abutment surfaces and the center line of the limiting block gradually increases according to a set thickness.

[0015] In some embodiments, the device further includes fasteners, a plurality of reinforcing ropes, and connectors; the fasteners are disposed on the limiting block, the connectors are disposed on the protruding structure, and one end of the reinforcing rope is connected to the fasteners and the other end is connected to the connectors.

[0016] This invention provides an alignment fixture for processing photovoltaic modules. During alignment, the side end of a limiting block abuts against the extended adhesive film layer of the laminate. Because a raised structure protrudes from the side end of the limiting block, it can push the misaligned panel to move. Multiple limiting blocks and raised structures work together to correct the misaligned panel to the correct position. This invention effectively eliminates / reduces panel misalignment during laminate alignment, reducing the risk of misalignment in laminate manufacturing. Attached Figure Description

[0030] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This utility model provides an alignment fixture for processing photovoltaic modules, including a fixture body, which includes a worktable and a limiting block. The worktable is provided with a placement position for placing the laminate in the photovoltaic module, and the limiting block is located at the side end of the worktable.

[0032] During the alignment operation of the laminate, the limiting blocks move to the edge of the laminate and abut against the edge; multiple limiting blocks are distributed around the laminate, pushing and aligning it towards the center, thereby achieving the alignment and correction of the laminate. The laminate is an unassembled photovoltaic module, which includes a multi-layer structure, such as a first panel, an intermediate layer, and a second panel. The intermediate layer includes a first encapsulating film layer, solar cells, and a second encapsulating film layer.

[0033] Among them, a protruding structure can be set on the limiting block. The protruding structure abuts against and interferes with part of the panel of the laminate, and the panel is moved to be aligned, eliminating the influence of misalignment space on the alignment operation and reducing the possibility of panel misalignment.

[0034] The following description, in conjunction with the accompanying drawings, details the various structures, positional relationships, and connection relationships of the alignment fixture for processing photovoltaic modules provided in this embodiment of the present invention.

[0035] As shown in Figures 1 to 6, in this embodiment of the present invention, the side end of the limiting block 10 includes an adjustment position, and the adjustment position is provided with a protruding structure 11. The side end of the limiting block 10 is used to abut against the edge of the laminate 20 to be aligned. Multiple limiting blocks 10 cooperate to align each panel 22 of the laminate 20. The protruding structure 11 can further adjust the position of individual panels 22 that may be misaligned based on the alignment of the side end of the limiting block 10, thereby ensuring the alignment adjustment effect of the laminate 20 and eliminating or reducing the occurrence of offset.

[0036] The protruding structure 11 is used to abut against the side of one of the panels 22 of the laminate 20 to align the first panel with the second panel. For example, during the alignment operation, if the first panel is at the bottom and the adhesive film layer 21 extends out of the laminate 20 to the side of the first panel, the second panel may be misaligned; conversely, if the second panel is at the bottom, the first panel may be misaligned. The protruding structure 11 is used to adjust the position of the misaligned first or second panel.

[0037] For example, the first and second panels may be made of glass, polymer materials (such as ethylene-tetrafluoroethylene copolymer or polyethylene terephthalate), or transparent back panels (such as polyvinyl fluoride composite film or thermoplastic elastomer).

[0038] The side end of the limiting block 10 has a certain height. Within this height range, different positions are used to abut against different positions of the alignment laminate 20. Due to the interference of the extended adhesive film layer 21, some panels 22 still have movable space (misalignment space) even when the limiting block 10 is moved into place. The position of the side end of the limiting block 10 corresponding to this part of the panel 22 is the adjustment position. A protruding structure 11 is provided at the adjustment position, and the protruding structure 11 further abuts against the corresponding panel 22. During the alignment operation, under the joint action of the limiting block 10 and the protruding structure 11, the entire structure of the laminate 20 can be aligned and limited, thereby eliminating or reducing the occurrence of displacement.

[0039] For example, the protruding structure 11 can be formed on the adjustment position on the side end of the limiting block 10 after the limiting block 10 is formed, or, for example, the protruding structure 11 can be integrally formed with the limiting block 10. For example, a stepped structure is formed on the side end of the limiting block 10, and the protruding part in this structure is the protruding structure 11.

[0040] For example, in this embodiment of the invention, the number of protrusions 11 (adjustment positions) on the limiting block 10 can be one or more, and the number or position of the protrusions 11 is determined according to the structure of the laminate 20 to be aligned. For example, if the laminate 20 includes an additional panel 22 that may shift, then a protrusion 11 is provided at a corresponding position on the side end of the limiting block 10; or if the laminate 20 includes multiple panels 22 that may shift, then a protrusion 11 is provided at a corresponding position on the side end of the limiting block 10.

[0041] In this embodiment of the invention, the side end of the limiting block 10 abuts against the adhesive film layer 21 extending from the laminate 20, and the protruding structure 11 abuts against the panel 22 of the laminate 20 (which may be additionally offset). Specifically, there is a certain gap between the edge of the protruding structure 11 and the adhesive film layer 21 in the height direction of the limiting block 10, ensuring that during alignment, the side end of the limiting block 10 abuts against the adhesive film layer 21, while there is no contact between the protruding structure 11 and the adhesive film layer 21. That is, the adjustment position and the height of the protruding structure 11 need to be designed according to the laminate 20.

[0042] For example, in this embodiment of the present invention, the shape of the protrusion structure 11 is not limited, as long as it can meet the abutment limit; for example, the cross-sectional shape of the protrusion structure 11 is rectangular, semi-circular or trapezoidal or other shapes.

[0043] For example, in this embodiment of the invention, the material of the protruding structure 11 is not limited; it only needs to satisfy the abutment and limiting function. However, preferably, the material of the protruding structure 11 can be a hard material that is not easily deformed after abutment occurs. For example, its material can be hard rubber or fabric.

[0044] The range of movement of panel 22 in the misalignment space is determined by the thickness of adhesive film layer 21. As the thickness of adhesive film layer 21 changes, the misalignment range of misalignment space will also change, and the protrusion size of the corresponding protrusion structure 11 will also change. Therefore, in different application scenarios, it is necessary to select the limiting block 10 of protrusion structure 11 with different protrusion sizes.

[0045] In this embodiment of the invention, to improve the versatility of the alignment tooling, the protrusion size of the protrusion structure 11 can be set to be adjustable to meet different alignment requirements. For example, if the thickness of the adhesive film layer 21 extending from the laminate 20 changes, the protrusion size of the corresponding protrusion structure 11 needs to change accordingly. For instance, if the thickness of the adhesive film layer 21 increases, the protrusion size of the protrusion structure 11 needs to increase; conversely, if the thickness of the adhesive film layer 21 decreases, the protrusion size of the protrusion structure 11 needs to decrease.

[0046] Therefore, in this embodiment of the invention, the protruding structure 11 also needs to be provided with a structure in which the protrusion size is variable. For example, the protruding structure 11 includes at least one layer of stacked structure 13, and the at least one layer of stacked structure 13 is arranged along the protrusion direction of the protruding structure 11; the number of stacked structures 13 can adjust the protrusion size of the protruding structure 11. The protrusion direction can be understood as: the direction of radial extension along the limiting block 10.

[0047] The raised structure 11 has multiple layers in the protruding direction. The protrusion size of the raised structure 11 can be adjusted by changing the number of layers. For example, the superimposed structure 13 includes adhesive tape. The number of layers of adhesive tape is used to adjust the protrusion size of the raised structure 11. The more layers of adhesive tape, the larger the protrusion size of the raised structure 11, and vice versa. When it is necessary to adjust the protrusion size of the raised structure 11, the number of layers of adhesive tape can be increased or some adhesive tape can be torn off to reduce the number of layers.

[0048] For example, the tape can be positioned on the side where the raised structure 11 abuts against the panel 22, or the raised structure 11 can be connected to the limiting block 10 via the tape.

[0049] For example, the tape is a pressure-sensitive tape.

[0050] For example, the protrusion size of each layer of tape can be set according to the application scenario. If the required range of protrusion size adjustment is large, tape with a larger protrusion size can be set, and the adjustment range of the protrusion size is larger when each layer or layer of tape is torn off; if the required range of protrusion size adjustment is small, tape with a smaller protrusion size can be set, and the adjustment range of the protrusion size is smaller when each layer or layer of tape is torn off; or, tapes with different protrusion sizes can be set in the same protrusion structure 11, for example, tapes with larger protrusion sizes and tapes with smaller protrusion sizes can be alternately set along the protrusion direction. For example, the protrusion size of each layer of tape is less than 0.1 mm.

[0051] In this embodiment of the present invention, the superimposed structure 13 of the protrusion structure 11 is not limited to this, and can also be other superimposed structures. For example, the superimposed structure 13 is a magnetic structure, and the protrusion size of the protrusion structure 11 can be adjusted by changing the protrusion size of part of the magnetic structure.

[0052] In this embodiment of the utility model, the protrusion size of the protrusion structure 11 can also be changed by replacing the protrusion structure 11. The same limit block 10 is equipped with multiple protrusion structures 11, and the protrusion sizes of different protrusion structures 11 are different. When it is necessary to adjust the protrusion size of the protrusion structure 11, the protrusion structure 11 with the corresponding protrusion size is replaced. In order to facilitate the replacement operation of the protrusion structure 11, the protrusion structure 11 and the adjustment position can be set to a detachable connection.

[0053] For example, the protruding structure 11 is connected to the adjustment position by a detachable method such as snap-fit, magnetic attraction, or plug-in. When it is necessary to replace the protruding structure 11 with one of the corresponding protrusion size, simply remove the currently connected protruding structure 11 and connect the new protruding structure 11 to the adjustment position.

[0054] Referring to Figures 1 to 6, in this embodiment of the present invention, the limiting block 10 is a columnar structure. For example, the cross-sectional shape of the columnar structure can be circular, rectangular, or polygonal. The protruding structure 11 can be a segment structure, that is, it has a certain length, or it can be a ring structure. When a ring structure is used, the protruding structure 11 is sleeved on the limiting block 10 and is detachably connected to the limiting block 10.

[0055] In this embodiment of the invention, a detachable connection between the protruding structure 11 and the limiting block 10 can be achieved through a reinforcement structure. For example, the alignment fixture for processing photovoltaic modules includes a fastener 121, a reinforcing rope 122, and a connector 123; the fastener 121 is disposed on the limiting block 10, the connector 123 is disposed on the protruding structure 11, one end of the reinforcing rope 122 is connected to the fastener 121, and the other end is connected to the connector 123.

[0056] As shown in Figures 4 and 5, the fastener 121 is set at the top of the limit block 10. For example, the fastener 121 is a connecting block, which is fixedly connected to the limit block 10. One end of the reinforcing rope 122 is fixedly connected to the connecting block. If a through hole is provided on the connecting block, the end of the reinforcing rope 122 passes through the through hole and is then bound to the connecting block, thereby achieving the connection.

[0057] For example, connector 123 includes a connecting hole located at the top of protruding structure 11. The other end of reinforcing rope 122 passes through the connecting hole and is bound to protruding structure 11. Reinforcing structure 12 can fix the annular protruding structure 11 to the limiting block 10.

[0058] For example, the alignment fixture for processing photovoltaic modules includes multiple reinforcing ropes 122, which can be evenly arranged to improve the stability of the connection of the protruding structure 11. For example, the number of reinforcing ropes 122 in the alignment fixture for processing photovoltaic modules is 2 to 4.

[0059] In this embodiment of the invention, the position of the protruding structure 11 on the limiting block 10 can also be changed by adjusting the length of the reinforcing rope 122 to adapt to panels 22 of different heights. Specifically, when adjusting the length of the reinforcing rope 122, the length of the reinforcing rope 122 is adjusted at the connecting block, and after being adjusted to the desired position, it is connected to the connecting block.

[0060] In this embodiment of the utility model, the protruding structure 11 can also be detachably connected to the limiting block 10 in the form of a clamp.

[0061] For example, the protrusion structure 11 includes a first substructure 111 and a second substructure 112 that are detachably connected. The first substructure 111 and the second substructure 112 are configured to form an annular structure that adapts to the shape of the limiting block 10 when assembled.

[0062] For example, the protrusion structure 11 also includes a locking structure 113; one end of the first substructure 111 and the second substructure 112 are rotatably connected, and the other end is connected through the locking structure 113.

[0063] For example, the first substructure 111 and the second substructure 112 are symmetrically arranged and are semi-circular structures respectively. One end of the first substructure 111 and the second substructure 112 are rotatably connected by a rotating shaft. During disassembly, the locking structure 113 is unlocked, the first substructure 111 and the second substructure 112 are sleeved on the limit block 10, and then the locking structure 113 is locked again.

[0064] For example, the locking structure 113 can be a snap-on or adjusting buckle, which can lock or unlock. Alternatively, the locking structure 113 can also be an adjustable length structure, such as a nylon buckle or a D-ring, etc. When adapting to limit blocks 10 with different outer diameters, the inner diameter of the protruding structure 11 can be appropriately changed by adjusting the length of the locking structure 113 to achieve the purpose of adaptation.

[0065] As shown in Figure 6, in this embodiment of the present invention, the protruding structure 11 includes multiple abutment surfaces 114 along the circumferential direction for abutting against the panel 22 of the laminate 20; the multiple abutment surfaces 114 are at different straight-line distances from the center line of the limiting block 10. The center line can be interpreted as a straight line perpendicular to the transverse cross-section of the limiting block 10 and passing through the centroid of the transverse cross-section. For example, when the cross-sectional shape of the limiting block 10 is circular or elliptical, the center line is perpendicular to and passes through the center of the cross-section of the limiting block 10; for example, when the cross-sectional shape of the limiting block 10 is a regular polygonal structure, the center line is perpendicular to and passes through the center of the cross-section of the limiting block 10; for example, when the cross-sectional shape of the limiting block 10 is irregular, the center line is perpendicular to and passes through the centroid of the cross-section of the limiting block 10.

[0066] The protruding structure 11 is detachably connected to the limiting block 10. In different alignment adjustment scenarios, the protruding structure 11 with different protrusion sizes can be replaced to achieve alignment adjustment and reduce deviation. The protrusion size of the protruding structure 11 can be changed by replacing it, or it can be adjusted by rotating it.

[0067] Each contact surface 114 is adapted to a protrusion size. When adjustment is required, first separate the protrusion structure 11 from the limit block 10. The protrusion structure 11 can rotate relative to the limit block 10. Rotate the required contact surface 114 to the adjustment position, and then lock the protrusion structure 11 onto the limit block 10.

[0068] For example, along the circumference of the protruding structure 11, the straight-line distance between the multiple abutment surfaces 114 and the center line of the limiting block 10 gradually increases according to the set protrusion size. For example, the protruding structure 11 is a polygonal structure, and except for the pivot structure and the locking structure 113, the other sides can be used to adjust the protrusion size of the protruding structure 11.

[0069] For example, the cross-sectional shape of the pre-protrusion structure is octagonal, and in addition to the pivot structure and locking structure 113, it can be adjusted to six positions. For example, the protrusion size of the same protrusion structure 11 can be adjusted from 0.7 mm to 1.2 mm, and the protrusion size range of adjacent sides differs by 0.1 mm. One protrusion structure 11 can provide at least 6 protrusion size selections, which can effectively reduce the number of protrusion structures 11 used, and the operation of adjusting the protrusion size of the protrusion structure 11 is simpler and faster.

[0070] The laminate 20 mainly includes a first panel, an adhesive film layer 21, and a second panel. The alignment operation of the photovoltaic module is used as an example to describe the alignment tooling for processing the photovoltaic module provided in this embodiment of the present invention.

[0071] As shown in Figures 1 to 7, the alignment fixture includes a worktable 30, on which a photovoltaic module placement position is set, and at least one limiting block 10 is set at the edge of the placement position. The limiting block 10 is connected to a moving structure, which can reciprocate the limiting block 10 towards or away from the placement position. The moving structure includes a slide rail and a drive device, etc., and its specific movement method is not limited.

[0072] For example, the photovoltaic module is rectangular in shape, and one or more limiting blocks 10 are provided on both sides of a set of opposite sides of the photovoltaic module, or, for example, one or more limiting blocks 10 are provided on each of the four sides of the photovoltaic module. Figure 7 illustrates the structure in which one limiting block 10 is provided on each of the four sides of the photovoltaic module, that is, each side end of the laminate 20 corresponds to one limiting block 10. For example, when one limiting block 10 is provided on the side of the photovoltaic module, the limiting block 10 can be centrally located on that side; when multiple limiting blocks 10 are provided on the side of the photovoltaic module, the multiple limiting blocks 10 can be evenly distributed on that side.

[0073] During alignment, the laminate 20 is placed horizontally, with the first panel below and the second panel above, extending out from the encapsulant layer 21 of the photovoltaic module, naturally curving to seal the outside of the first panel. In this structure, there is a misalignment space at the edge of the second panel.

[0074] During the alignment process, the moving structure is activated, and multiple limiting blocks 10 move synchronously toward the photovoltaic module. The sides of the limiting blocks 10 abut against the adhesive film layer 21, while the protruding structure 11 abuts against the edge of the second panel. Under the combined action of the multiple limiting blocks 10, the alignment of the first panel, the adhesive film layer 21, and the second panel is achieved. The protrusion size of the protrusion structure 11 is the same as or nearly the same as the protrusion size of the adhesive film layer 21.

[0075] The adhesive film layer 21 includes at least a first adhesive film layer, a battery cell, and a second adhesive film layer. The friction between each layer of the adhesive film layer 21 is greater than the friction between the adhesive film layer 21 and the first panel and the second panel. Therefore, during the alignment operation, the second panel is pushed to move relative to the adhesive film layer 21, and the offset of the adhesive film layer 21 is negligible.

[0076] After the alignment operation is completed, the moving structure moves in the opposite direction to release contact with the photovoltaic module. The photovoltaic module is then ready for the next process after the alignment operation is completed.

[0077] This invention provides an alignment fixture for processing photovoltaic modules. During alignment, the side end of the limiting block 10 abuts against the adhesive film layer 21 extending from the laminate 20. Since the protruding structure 11 protrudes from the side end of the limiting block 10, it can push the misaligned panel 22 to move. The cooperation of multiple limiting blocks 10 and protruding structures 11 can correct the misaligned panel 22 to the correct position. This invention effectively eliminates / reduces the misalignment of the panel 22 during the alignment operation of the laminate 20, reducing the risk of misalignment during the manufacturing of the laminate 20.
