Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to a stringing auxiliary tooling and photovoltaic module production equipment. Background Technology

[0002] The photovoltaic (PV) industry chain begins with upstream silicon raw materials, proceeding through metallic silicon refining, polycrystalline silicon preparation, silicon rod pulling, and silicon wafer cutting, to the midstream production of solar cells and PV modules, and finally integrating downstream into PV power plant systems. In this process, the design and manufacturing of PV modules is the heart of the solar power system, its core function being the efficient and stable conversion of captured solar energy into electrical energy. Completed PV modules, as the core component of a solar power system, can be flexibly applied in various scenarios: in off-grid systems, they can store the converted electrical energy in batteries for emergencies or to power independent loads; while in grid-connected systems, they can directly connect the electrical energy to the grid, realizing the widespread supply and utilization of clean energy.

[0003] The production process of photovoltaic modules involves multiple complex steps, including string welding, layout, stacking, lamination, glass bonding, EL (Electroluminescence) visual inspection, edge sealing, lamination, edge trimming, flipping inspection, frame assembly, and junction box welding. After string welding is completed, some defective cell strings need to be reworked. The reworked cell strings need to be manually placed on the glass for layout, and then stacked by machine.

[0004] However, during the layout process of the returned battery strings, each time a battery string is placed, a crawler fixture (similar to a ruler) is needed to measure the distance between the battery string and the glass edge or between adjacent battery strings to ensure correct positioning. This process is tedious and inefficient, and the error of human measurement is relatively large, which can easily cause poor string spacing and affect the yield of subsequent stacking processes. Utility Model Content

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] The design and manufacturing of photovoltaic (PV) modules is the heart of a solar power system. The PV module production process involves numerous complex steps, including string welding, layout, stacking, lamination, glass assembly, EL (Electroluminescence) visual inspection, edge sealing, lamination, edge trimming, flipping inspection, framing, and junction box welding. After string welding, some defective cell strings need to be reworked. These reworked strings are then manually placed on glass for layout before being stacked by machine.

[0046] However, during the layout process of the returned battery strings, each time a battery string is placed, a climbing tool (similar to a ruler) is needed to measure the distance between the battery string and the glass edge or between adjacent battery strings to ensure correct positioning. This process is tedious and inefficient. Furthermore, human measurement is prone to significant errors, which affect the positioning accuracy of the battery strings, easily leading to poor string spacing, affecting the yield of subsequent lamination processes, and ultimately impacting the final yield of the photovoltaic module.

[0047] For this purpose, please refer to Figures 1 to 4 This application provides a stringing auxiliary tooling 100. Figure 1 This is a schematic diagram of a string-arranging auxiliary tooling 100 according to an embodiment of this application, viewed from one perspective. Figure 2 for Figure 1 The schematic diagram of the stringing auxiliary fixture 100 shown is presented from another perspective. Figure 3 for Figure 1 The schematic diagram of the stringing auxiliary fixture 100 shown is from a third perspective. Figure 4 for Figure 1 The schematic diagram of the stringing auxiliary tooling 100 shown is from the fourth perspective.

[0048] The string arrangement auxiliary tooling 100 is used in photovoltaic module production equipment (not shown) to arrange the returned cell strings (not shown) during the photovoltaic module production process. Understandably, during photovoltaic module production, multiple cell strings need to be arranged on photovoltaic glass to facilitate subsequent operations such as stacking and welding, followed by lamination processes to ultimately form the photovoltaic module.

[0049] After the battery strings are welded together, some defective strings need to be repaired, while the good strings proceed directly to subsequent processes such as layout and stacking. After repair, the defective strings become good and can still be used to manufacture photovoltaic modules. This application focuses on how repaired battery strings are manufactured into photovoltaic modules.

[0050] In this application, the photovoltaic module production equipment includes at least a conveyor line (not shown), a welding device (not shown), and the string arranging auxiliary fixture 100 of this application. The string arranging auxiliary fixture 100 and the welding device are installed along the conveyor line. The conveyor line transports photovoltaic glass (not shown) to the string arranging auxiliary fixture 100, which positions it on the photovoltaic glass. Subsequently, multiple cell strings are placed into the string arranging auxiliary fixture 100.

[0051] Multiple battery strings are positioned using a string-arranging auxiliary fixture 100 to ensure that the distance between the battery strings and the edge of the photovoltaic glass meets requirements, and that the spacing between adjacent battery strings meets the fabrication requirements of the photovoltaic module. This achieves accurate positioning of multiple battery strings relative to the photovoltaic glass. The entire positioning process is accomplished by the string-arranging auxiliary fixture 100, eliminating the need for manual measurement.

[0052] Subsequently, the conveyor line transports the positioned battery strings and photovoltaic glass to the welding device, where multiple battery strings are welded together. Then, the conveyor line continues to transport the stacked battery strings and photovoltaic glass for further processing to complete the fabrication of the photovoltaic module. This process will not be described in detail below.

[0053] In this application, the string-arranging auxiliary fixture 100 is mainly used for arranging and positioning reworked battery strings. Of course, in other embodiments of this application, the string-arranging auxiliary fixture 100 can also be used for arranging and positioning good battery strings, or it can be used to position other components that require string-arranging positioning. This application only uses the string-arranging auxiliary fixture 100 for arranging and positioning battery strings as an example for illustration.

[0054] The string arrangement auxiliary tooling 100 of this application can accurately arrange and position multiple battery strings, reducing the complexity of string arrangement and improving the efficiency of string arrangement. Furthermore, the entire string arrangement and positioning process does not require manual measurement by operators, ensuring accurate string spacing of battery strings, reducing errors caused by human measurement, and improving the yield of subsequent stacking and welding processes.

[0055] See Figures 1 to 5 In one embodiment, the stringing auxiliary fixture 100 includes an auxiliary frame 110 having a plurality of positioning holes 111. Each positioning hole 111 accommodates a battery string, enabling the auxiliary frame 110 to position the plurality of battery strings in a row on the photovoltaic glass. Figure 5 for Figure 1 A schematic diagram of the auxiliary frame 110 in the stringing auxiliary fixture 100 shown.

[0056] The auxiliary frame 110 is the main structure for positioning the battery string. For example... Figures 1 to 4 As shown, the first direction is the length direction of the auxiliary frame 110, the second direction is the width direction of the auxiliary frame 110, and the corresponding third direction is the height direction, top and bottom direction, and up and down direction of the auxiliary frame 110. The first direction, the second direction, and the third direction also apply to other components of the stringing auxiliary fixture 100, which will not be described in detail below.

[0057] The auxiliary frame 110 extends along the first and second directions, thus covering the photovoltaic glass in both directions to accurately position multiple battery strings onto the photovoltaic glass. Furthermore, the auxiliary frame 110 has multiple positioning holes 111 that penetrate the auxiliary frame 110 along a third direction. In other words, the auxiliary frame 110 has multiple open sections, which serve as the positioning holes 111.

[0058] When using the auxiliary frame 110 to position the battery strings, the auxiliary frame 110 is placed on the photovoltaic glass. Then, each battery string is placed in the positioning holes 111 of the auxiliary frame 110. The multiple positioning holes 111 can arrange and position the battery strings. Subsequently, the auxiliary frame 110 is removed from the photovoltaic glass, leaving the battery strings on the photovoltaic glass.

[0059] In other words, when using the auxiliary frame 110 to position multiple battery strings, the battery strings are directly placed into the corresponding positioning holes 111. The positioning holes 111 can accommodate the battery strings, thus achieving the proper positioning of the reworked battery strings. It is understandable that after the battery strings are placed into the positioning holes 111, there is a certain gap between the edge of the battery string and the inner wall of the positioning hole 111. The positioning error due to this gap is within the required range.

[0060] In this way, after the auxiliary frame 110 positions the battery string through multiple positioning holes 111, the auxiliary frame 110 moves upward along a third direction to detach from the photovoltaic glass, leaving the battery string on the surface of the photovoltaic glass. Furthermore, the auxiliary frame 110 will not scrape against the battery string, thus avoiding any impact on its position. In this way, the distance between each battery string and the edge of the photovoltaic glass, as well as the spacing between adjacent battery strings, can meet the requirements for subsequent photovoltaic module fabrication.

[0061] In this way, during the process of arranging and positioning multiple battery strings through the auxiliary frame 110, the battery strings can be directly placed in the positioning holes 111 without the need for operators to manually measure the spacing between the battery strings. This simplifies the arrangement process, improves process efficiency, reduces errors caused by human measurement, and ensures accurate spacing between battery strings, thereby improving the yield of subsequent stacking processes and ultimately improving the yield of photovoltaic modules.

[0062] See Figures 1 to 5 In one embodiment, the auxiliary frame 110 includes a mounting frame 112 and a plurality of positioning baffles 113 disposed in the mounting frame 112, and a plurality of positioning holes 111 are formed between the mounting frame 112 and the positioning baffles 113. The plurality of positioning holes 111 are arranged in rows and columns.

[0063] Mounting frame 112 is the frame of auxiliary frame 110, positioning baffle 113 is the partition plate of auxiliary frame 110, multiple positioning baffles 113 extend along the first direction and the second direction and are disposed in mounting frame 112, the edges of multiple positioning baffles 113 are connected to mounting frame 112 to divide the inner cavity of mounting frame 112 into multiple independent cavities, each cavity being a positioning hole 111.

[0064] Multiple positioning holes 111 are arranged in rows and columns along the first and second directions in the mounting frame 112. In this way, one battery string is independently installed in each positioning hole 111, and multiple positioning holes 111 enable independent positioning of multiple battery strings, so as to ensure the accuracy of positioning of each battery string. There is no need to manually adjust the position of the battery strings, thereby improving process efficiency and increasing the yield of photovoltaic modules.

[0065] See Figures 1 to 5 In one embodiment, the size of the positioning hole 111 is adapted to the size of the battery string. That is, the size of the positioning hole 111 along the first direction is adapted to the length of the battery string, and the size of the positioning hole 111 along the second direction is adapted to the width of the battery string. In this way, the battery string can be installed into the positioning hole 111 that is adapted to its size, and the positioning hole 111 enables accurate positioning of the battery string.

[0066] Understandably, different photovoltaic module designs / specifications result in different cell string sizes. In this case, the auxiliary frame 110 and its positioning holes 111 can be designed according to the cell string size, ensuring that the size and number of the positioning holes 111 meet the production requirements of the photovoltaic module. During photovoltaic module production, the corresponding string auxiliary fixture 100 can be directly replaced.

[0067] See Figures 1 to 5 In one embodiment, the plurality of positioning baffles 113 include a plurality of first baffles 1131 and at least one second baffle 1132 disposed in the mounting frame 112. The plurality of first baffles 1131 extend along a first direction and are spaced apart along a second direction. The second baffle 1132 extends along the second direction and connects each of the first baffles 1131 and the mounting frame 112. A plurality of positioning holes 111 are formed between the mounting frame 112, the first baffles 1131 and the second baffles 1132.

[0068] The first baffle 1131 extends along the first direction, and a plurality of first baffles 1131 are spaced apart along the second direction. The two ends of the first baffle 1131 along the first direction are respectively connected to the mounting frame 112. At least one second baffle 1132 extends along the second direction, and the two ends of the second baffle 1132 along the second direction are also respectively connected to the mounting frame 112.

[0069] At this time, after the first baffle 1131 and the second baffle 1132 are connected to the mounting frame 112, the inner cavity of the mounting frame 112 can be divided into a grid-like structure, and the space in the grid-like structure is the positioning hole 111. That is, the first baffle 1131, the second baffle 1132 and the mounting frame 112 form the positioning hole 111, through which the battery string is accommodated, and the first baffle 1131 and the second baffle 1132 separate adjacent battery strings to ensure the string spacing between adjacent battery strings.

[0070] In one embodiment, the mounting frame 112, the first baffle 1131, and the second baffle 1132 are made of metal. This improves the structural strength of the auxiliary frame 110, thereby increasing its load-bearing capacity, extending its service life, and facilitating the arrangement and positioning of the battery strings.

[0071] In one embodiment, the first baffle 1131 and the second baffle 1132 are fixed to the mounting frame 112 by welding. This improves the structural strength of the connection between the mounting frame 112, the first baffle 1131, and the second baffle 1132, prevents breakage at the connection, and improves the reliability of battery string positioning.

[0072] See Figures 1 to 5In one embodiment, the thicknesses of the first baffle 1131 and the second baffle 1132 are adapted to the distance between adjacent cell strings in the photovoltaic module. The first baffle 1131 and the second baffle 1132 can separate the cell strings. After limiting the thickness of the first baffle 1131 and the second baffle 1132, the first baffle 1131 and the second baffle 1132 can separate the cell strings, ensuring the spacing between adjacent cell strings.

[0073] In other words, the thickness of the first baffle 1131 and the second baffle 1132 is designed according to the shape / specification of the photovoltaic module. It is understandable that the spacing between the cell strings is different in photovoltaic modules of different shapes / specifications. The first baffle 1131 and the second baffle 1132 of corresponding thickness are used to separate adjacent cell strings to meet the manufacturing requirements of the corresponding photovoltaic modules.

[0074] See Figures 1 to 5 In this embodiment, when there is only one second baffle 1132, the second baffle 1132 is located in the middle region of the first baffle 1131. At this time, the second baffle 1132 divides the first baffle 1131 into two segments along the first direction. Furthermore, the auxiliary frame 110 forms two positioning holes 111 along the first direction, so that the photovoltaic module has two battery strings along the first direction, which meets the manufacturing requirements of the photovoltaic module.

[0075] Of course, in other embodiments of this application, when there are at least two second baffles 1132, the at least two second baffles 1132 are spaced apart along the first direction. After the at least two second baffles 1132 are spaced apart along the first direction, the first baffle 1131 can be divided into at least three segments along the first direction. Furthermore, the auxiliary frame 110 forms at least three positioning holes 111 along the first direction, so that the photovoltaic module has at least three battery strings along the first direction, meeting the battery string fabrication requirements.

[0076] See Figures 1 to 5 In one embodiment, the mounting frame 112 includes two first side beams 1121 and two second side beams 1122. The two first side beams 1121 extend along a first direction and are arranged opposite each other along a second direction. The two second side beams 1122 extend along the second direction and are arranged opposite each other along the first direction. The two ends of the first side beams 1121 are connected to the second side beams 1122 to form the mounting frame 112. The two ends of the positioning baffle 113 are connected to the first side beams 1121 and the second side beams 1122.

[0077] The two first side beams 1121 are opposite sides of the mounting frame 112, such as the long side, and the two second side beams 1122 are opposite sides of the mounting frame 112, such as the short side. The two first side beams 1121 extend along a first direction, and the two second side beams 1122 extend along a second direction. The first side beams 1121 and the second side beams 1122 are connected at their ends to form a quadrilateral mounting frame 112.

[0078] The first baffle 1131 and the second baffle 1132 are disposed in the mounting frame 112. The first baffle 1131 is arranged parallel to the first side beam 1121, and both ends of the first baffle 1131 are connected to the second side beam 1122. The second baffle 1132 is arranged parallel to the second side beam 1122, and both ends of the second baffle 1132 are connected to the first side beam 1121. In this way, the first side beam 1121 and / or the second side beam 1122 can form a plurality of positioning holes 111 with the first baffle 1131 and the second baffle 1132.

[0079] In one embodiment, the first side beam 1121 and the second side beam 1122 are made of metal. This improves the structural strength of the mounting frame 112. Furthermore, the first side beam 1121 and the second side beam 1122 are connected by welding to ensure the reliability of the connection.

[0080] See Figures 1 to 4 In one embodiment, the stringing auxiliary fixture 100 further includes a support column 120 and a telescopic component. The support column 120 is located on the side of the auxiliary frame 110, and the telescopic component is disposed on the support column 120. The auxiliary frame 110 is disposed at the output end of the telescopic component, and the telescopic component can drive the auxiliary frame 110 to move up and down in a third direction so that the auxiliary frame 110 abuts against or detaches from the photovoltaic glass.

[0081] The support column 120 is a component that provides support for the auxiliary tooling 100 for the conveyor belt assembly. The support column 120 is installed on the ground or frame on the side of the conveyor belt. The support column 120 extends in a third direction and is located on the side of the auxiliary frame 110. The top of the support column 120 is connected to a telescopic assembly, and the output end of the telescopic assembly is connected to the auxiliary frame 110.

[0082] The support column 120 supports the telescopic component, which in turn supports the auxiliary frame 110. The telescopic component can output lifting and lowering motion in a third direction, thereby driving the auxiliary frame 110 to rise or fall synchronously in a third direction.

[0083] After the photovoltaic glass moves to below the auxiliary frame 110, the telescopic component drives the auxiliary frame 110 to descend along a third direction. When the auxiliary frame 110 abuts against the photovoltaic glass, the telescopic component stops driving the auxiliary frame 110 to descend. Subsequently, the operator places the battery strings sequentially into the positioning holes 111 to achieve the arrangement and positioning of the battery strings.

[0084] After the battery strings are arranged and positioned, the telescopic component drives the auxiliary frame 110 to rise, and the conveyor line transports the photovoltaic glass of the battery strings to the welding device. The welding device then welds the battery strings to complete the stacking operation.

[0085] See Figures 1 to 4 In one embodiment, the telescopic assembly includes a telescopic drive component and a first connecting component 130. The telescopic drive component is disposed on the support column 120, and the first connecting component 130 is disposed at the output end of the telescopic drive component along a third direction and connected to the auxiliary frame 110. The telescopic drive component drives the first connecting component 130 to move the auxiliary frame 110 up and down along a third direction.

[0086] The telescopic drive component is the power component of the telescopic assembly, and the first connecting component 130 is the output component of the telescopic assembly. The telescopic drive component is disposed on the support column 120, and its output end is connected to the first connecting component 130. The first connecting component 130 then connects to the first baffle 1131 and / or the second baffle 1132 of the auxiliary frame 110. In this way, the telescopic drive component can drive the first connecting component 130 to move up and down synchronously, thereby causing the first connecting component 130 to drive the auxiliary frame 110 to move up and down synchronously.

[0087] Optionally, the telescopic drive component is a linear motor or a telescopic cylinder. The output end of the linear motor or telescopic cylinder is connected to the first connecting component 130. Of course, in other embodiments of this application, the telescopic drive component may also be a motor and a ball screw component, a gear and rack component, etc. The motor drives the ball screw component or the gear and rack component to move, so as to output a lifting motion along a third direction, thereby driving the first connecting component 130 to lift synchronously.

[0088] It is worth noting that the type of telescopic drive component is not limited in principle, as long as the telescopic drive component can output lifting and lowering motion to drive the first connecting component 130 to lift and lower synchronously. Optionally, the first connecting component 130 can be a connecting rod or a connecting plate, etc. In this way, the output end of the telescopic drive component can drive the auxiliary frame 110 to lift and lower synchronously through the connecting plate or connecting rod, etc. Optionally, the first connecting component 130 can be made of metal.

[0089] See Figures 1 to 4 , Figure 6 and Figure 7In one embodiment, the telescopic assembly further includes a second connecting member 140, which extends along a second direction and is disposed at the end of the first connecting member 130 away from the telescopic drive member. The second connecting member 140 is connected to the top of the auxiliary frame 110 to avoid the positioning hole 111. Figure 6 for Figure 2 The image shown is a magnified view of the stringing auxiliary fixture 100 at point A. Figure 7 for Figure 3 The enlarged view of the stringing auxiliary fixture 100 at point B.

[0090] The second connecting component 140 is disposed on the top of the auxiliary frame 110 along the second direction, and the bottom of the first connecting component 130 is connected to the second connecting component 140. The second connecting component 140 increases the contact area between the second connecting component 140 and the auxiliary frame 110, which facilitates the connection between the first connecting component 130 and the auxiliary frame 110 and ensures the reliability of the connection between the first connecting component 130 and the auxiliary frame 110.

[0091] Meanwhile, after the second connecting component 140 is disposed on the top of the auxiliary frame 110, the second connecting component 140 is connected to the second baffle 1132 to avoid the positioning hole 111. In this way, the second connecting component 140 will not occupy the space in the positioning hole 111, and thus will not occupy the space occupied by the battery string in the positioning hole 111, ensuring that the battery string is accurately arranged in the positioning hole 111, realizing the string positioning of multiple battery strings.

[0092] See Figures 1 to 4 , Figure 6 and Figure 7 In one embodiment, the second connecting component 140 includes a support plate 141 and a connecting plate 142. The connecting plate 142 is connected to the top of the auxiliary frame 110 along the second direction. The support plate 141 is disposed at the end of the connecting plate 142 away from the auxiliary frame 110 and is connected to the first connecting component 130. The longitudinal cross-sectional area of ​​the support plate 141 is greater than that of the connecting plate 142.

[0093] The bottom of the connecting plate 142 is connected to the top of the second baffle 1132, the top of the connecting plate 142 is connected to the bottom of the support plate 141, and the top of the support plate 141 is connected to the first connecting component 130. In this way, the first connecting component 130 can be connected to the auxiliary frame 110 through the support plate 141 and the connecting plate 142, ensuring the reliability of the connection between the first connecting component 130 and the auxiliary frame 110.

[0094] Meanwhile, the longitudinal cross-sectional shape of the connecting plate 142 is adapted to the longitudinal cross-sectional shape of the second baffle 1132, and the longitudinal cross-sectional area of ​​the support plate 141 is larger than that of the connecting plate 142, so that the support plate 141 protrudes from the side above the connecting plate 142, avoiding obstruction of the positioning hole 111, thereby facilitating the placement of the battery string into the positioning hole 111.

[0095] In one embodiment, the support plate 141 and the connecting plate 142 are integrally formed. This improves the structural strength of the second connecting component 140. In another embodiment, the support plate 141 and the connecting plate 142 are made of metal. This allows the support plate 141 and the connecting plate 142 to be reliably connected to the second baffle 1132 and the first connecting component 130 by welding.

[0096] See Figures 1 to 4 In one embodiment, the number of first connecting members 130 is at least two, and they are spaced apart along a second direction. The at least two first connecting members 130 connect the telescopic drive member and the second connecting member 140. By connecting the telescopic drive member and the second connecting member 140 with at least two first connecting members 130, the reliability of the connection between the telescopic assembly and the second connecting member 140 is improved, so that the telescopic assembly can accurately drive the auxiliary frame 110 to rise and fall.

[0097] In one embodiment, there is one telescopic drive component, which simultaneously connects to multiple first connecting components 130. For example, an adapter plate is disposed at the output end of the telescopic drive component, and each first connecting component 130 is connected through the adapter plate so that each first connecting component 130 can rise and fall synchronously.

[0098] Of course, in other embodiments of this application, the number of telescopic drive components is at least two, with each first connecting component 130 paired with one telescopic drive component. In this way, the telescopic drive components can drive the corresponding first connecting component 130 to rise and fall, and the various telescopic drive components can move synchronously through motor control or other means.

[0099] See Figures 1 to 4 In one embodiment, the stringing auxiliary tooling 100 further includes a support beam 150, which extends along a second direction and is disposed on a support column 120. A telescopic assembly is disposed on the support beam 150. The support beam 150 is a component for mounting the telescopic assembly to the support column 120. One end of the support beam 150 is disposed at the top of the support column 120, and the other end extends along the second direction.

[0100] At this time, the support beam 150 has a cantilever beam structure and is located above the auxiliary frame 110. The telescopic drive component is installed in the support beam 150. The telescopic drive component can drive the first connecting component 130 and the second connecting component 140 to drive the auxiliary frame 110 to rise and fall synchronously.

[0101] When the stringing auxiliary fixture 100 of this application is used, the conveyor line transports the photovoltaic glass to the bottom of the auxiliary frame 110. Then, the telescopic drive component drives the first connecting component 130 and the second connecting component 140 to drive the auxiliary frame 110 to descend in a third direction. When the auxiliary frame 110 comes into contact with the photovoltaic glass, the telescopic drive component stops driving the auxiliary frame 110 to descend.

[0102] Subsequently, the operators place the battery strings sequentially into the positioning holes 111 to achieve the arrangement and positioning of the battery strings. After the battery strings are arranged and positioned, the telescopic drive component drives the auxiliary frame 110 to rise, and the conveyor line transports the photovoltaic glass of the arranged battery strings to the welding device. The welding device then welds the arranged battery strings to complete the stacking welding operation.

[0103] The string-arranging auxiliary fixture 100 of this application can accurately and quickly place the battery strings into position, reducing manual operation time and improving work efficiency. At the same time, the standardized fixture design ensures the accuracy of battery string placement each time, avoiding a series of measurement errors. Furthermore, due to the accurate positioning of the battery strings, the quality of the subsequent shingling process can also be guaranteed, thereby improving the overall yield of photovoltaic modules.

[0104] Meanwhile, the support column 120 supports the telescopic component and the auxiliary frame 110, allowing the auxiliary frame 110 to rise and fall in a third direction, facilitating the arrangement and positioning of multiple battery strings in conjunction with the photovoltaic glass. Furthermore, to replace the auxiliary frame 110 with different models / specifications, the auxiliary frame 110 can be detached from the second connecting component 140, and the corresponding model / specification of the auxiliary frame 110 can be installed onto the second connecting component 140.

[0105] This application also provides a photovoltaic module manufacturing equipment, including a conveyor line, a welding device, and a string-arranging auxiliary fixture 100 as described in any of the above embodiments. The string-arranging auxiliary fixture 100 and the welding device are arranged at intervals along the conveyor line. The conveyor line is used to transport photovoltaic glass to the string-arranging auxiliary fixture 100, the string-arranging auxiliary fixture 100 is used to position the cell strings on the photovoltaic glass, and the conveyor line transports the photovoltaic glass of the stringed cell strings to the welding device for welding.

[0106] The photovoltaic module production equipment of this application, after adopting the aforementioned string-arranging auxiliary tooling 100, can accurately and quickly place the battery strings into position, reducing manual operation time and improving work efficiency. Simultaneously, the standardized tooling design ensures the accuracy of battery string placement each time, avoiding a series of measurement errors. Furthermore, due to the accurate positioning of the battery strings, the quality of the subsequent stacking process can also be guaranteed, thereby improving the overall yield of the photovoltaic modules.

[0107] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
