Description

Technical Field

[0001] This utility model relates to the field of solar cell manufacturing technology, and in particular to an anti-warping mechanism for a back contact cell. Background Technology

[0002] Back-contact (BC) battery technology moves the PN junction and metal contacts to the back of the battery, eliminating electrode obstruction on the front and increasing the area for absorbing sunlight, thereby improving conversion efficiency and generating more electricity. Furthermore, the absence of any wiring or electrodes on the front results in a clean and aesthetically pleasing appearance, potentially commanding a higher premium in the mid-to-high-end Western market due to its high efficiency, attractive design, and reliable safety. However, BC batteries are prone to warping after stringing, which is one of the most significant and challenging issues. Warping can lead to various defects such as paralleling, parallel stringing, excessive string length, microcracks, broken cells, and insufficient overlap between the solder strip and the busbar (exceeding the busbar's edge), significantly increasing production costs.

[0003] In the existing technology, common anti-warping fixtures for solar cells have the following drawbacks:

[0004] The anti-warping fixture for solar cells generates a reaction force by pushing the cells, primarily using cylinder control, springs, or a combination of both. However, these methods lack precision in force and distance control. The fixture also suffers from poor cooling, causing cells to be placed on the production line before they are fully cooled, resulting in them reverting to their previous warped state. Furthermore, the anti-warping molding process cannot achieve the desired plasticity, negatively impacting the effectiveness of the anti-warping process.

[0005] These problems severely impact the production efficiency and product quality of BC batteries, increase production costs, and limit the widespread application of BC battery technology. Therefore, developing an anti-warping mechanism capable of precisely controlling anti-warping force and distance, providing effective cooling, and performing plastic treatment at the desired amplitude has become a pressing technical challenge.

[0006] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0032] The following description, in conjunction with the accompanying drawings, provides a more detailed account of an anti-warping mechanism for a back-contact battery according to the present invention, illustrating preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the scope of the invention.

[0033] In the description of this specification, terms such as "one embodiment" or "some embodiments" mean that one or more embodiments of this specification include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0034] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0035] The anti-warping mechanism of the back contact battery according to an embodiment of this application is described below with reference to the accompanying drawings.

[0036] According to the anti-warping mechanism of the back contact battery in this embodiment of the present invention, please refer to... Figures 1 to 3The device includes a support 1, an anti-warping device, and a cooling device 4. The anti-warping device and the cooling device 4 are mounted on the support 1. The anti-warping device includes a motor 11 and a shaping component 2. The motor 11 drives the shaping component 2 to perform anti-warping shaping on the back contact battery 12. The cooling device 4 is connected to the shaping component 2 to cool the back contact battery 12 in contact with the shaping component 2.

[0037] Specifically, the anti-warping device uses the motor 11 to drive the molding component 2 to perform anti-warping molding on the back contact battery 12, thus solving the problem of battery 12 warping. The high-precision control of the motor 11 makes the molding process more accurate, thereby effectively reducing the warping of the battery 12. Furthermore, the cooling device 4 is connected to the molding component 2 to ensure that the back contact battery 12 in contact with the molding component 2 is cooled, preventing the battery 12 from reverting to warping after molding.

[0038] The bracket 1 can be made of hard alloy structure, such as I-beam, to ensure the load-bearing capacity and service life of the bracket 1. Furthermore, the bracket 1 can also be made of T-shaped aluminum alloy block, which can improve the load-bearing capacity of the bracket 1. At the same time, the T-shaped structure can also provide an installation position for the anti-warping device and the cooling device 4, making the anti-warping mechanism of the back contact battery compact.

[0039] According to the anti-warping mechanism of the back contact battery of this utility model embodiment, the cooperation between the shaping part 2 driven by the motor 11 and the cooling device 4 achieves effective anti-warping treatment of the back contact battery 12, solving the technical problem of battery 12 warping. Compared with the prior art, the technical solution of this application has higher shaping accuracy and cooling effect, effectively preventing the battery 12 from recovering its warping after shaping, improving production efficiency and the quality of the battery 12.

[0040] In some embodiments of this utility model, such as Figure 4 As shown, the cooling device 4 includes a cooling pipe 41, the molded part 2 is a heat-conducting part, the molded part 2 is provided with a cooling passage 21, and the cooling pipe 41 passes through the cooling passage 21.

[0041] Specifically, the design of the cooling pipe 41 allows the coolant to pass directly through the molded part 2, improving cooling efficiency. As a heat-conducting component, the molded part 2, with its cooling passage 21, effectively conducts the coolant, ensuring that the 12 battery cells can cool rapidly after anti-warping, preventing them from returning to their previous warped state. In a preferred embodiment, the cooling pipe 41 can be made of metal to improve thermal conductivity, and the cooling passage 21 of the molded part 2 can be achieved through machining or 3D printing technology to ensure a precise and efficient coolant flow path.

[0042] In other words, the design of the cooling device 4 effectively solves the problem of poor cooling effect of the battery anti-warping mechanism. The cooling device 4, through the cooling pipe 41 and the cooling passage 21 on the molded part 2, effectively cools the back contact battery 12 in contact with the molded part 2, thereby improving cooling efficiency and ensuring that the battery 12 can cool rapidly after anti-warping, avoiding a return to its previous warped state. Compared with the prior art, the technical solution of this application, by optimizing the design of the cooling device 4, significantly improves the cooling effect, solves the problem of insufficient cooling of the battery 12 after anti-warping, and thus improves production efficiency and product quality.

[0043] It should be noted that the coolant supplied to the cooling pipe 41 can be water, ethylene glycol, or polyethylene glycol, etc., which will not be elaborated here. The temperature range of the coolant can be adjusted arbitrarily within the range of -50℃ to 150℃.

[0044] In some embodiments of this utility model, such as Figure 1 , Figure 3 As shown, the adsorption structure 3 is installed on one end face of the support 1, located on opposite sides of the molding part 2. This design helps to position and fix the battery 12 during the anti-warping process, preventing unnecessary movement or deformation of the battery 12 during molding. The adsorption structure 3 provides additional support and stability, ensuring that the molding part 2 can effectively perform anti-warping operations on the battery 12, thereby improving the accuracy and effect of anti-warping.

[0045] Specifically, the adsorption structure 3 can be implemented in various ways, such as using magnetic materials or vacuum adsorption technology to adsorb the battery 12. As a preferred embodiment, the adsorption structure 3 can be designed to be adjustable to accommodate different battery sizes and shapes, thereby improving the versatility and adaptability of the device. Furthermore, the adsorption structure 3 can also work in conjunction with the cooling device 4, using the cooling effect of the cooling device 4 to further stabilize the shape of the battery 12 and prevent it from warping again after initial warping.

[0046] In other words, by installing the adsorption structure 3 on one end face of the bracket 1 and setting it on opposite sides of the molding part 2, this application effectively solves the problem of the position and function of the adsorption structure 3 in the anti-warping device of the back contact battery 12. This design not only improves the accuracy and effect of anti-warping, but also enhances the stability and adaptability of the device, thereby solving the problem that the battery 12 is prone to movement or deformation during the anti-warping process in the prior art.

[0047] In some embodiments of this utility model, such as Figures 1-3 As shown, the anti-warping device also includes a transmission assembly 8, which is installed on the end of the bracket 1 away from the adsorption structure 3. The motor 11 drives the transmission assembly 8, and the transmission assembly 8 is connected to a plurality of the shaping parts 2.

[0048] Specifically, the transmission assembly 8, driven by the motor 11, can effectively transmit power to multiple shaping parts 2, enabling these shaping parts 2 to work collaboratively to perform anti-warping shaping on multiple back contact batteries 12. The transmission assembly 8 can employ methods such as slide rail drive, chain drive, or belt drive to ensure uniform power transmission. As a preferred embodiment, the transmission assembly 8 can be designed to be adjustable to accommodate back contact batteries 12 of different sizes and shapes. Furthermore, the transmission assembly 8 can also integrate sensors to monitor the position and pressure of the shaping parts 2 in real time, thereby achieving more precise control.

[0049] In other words, by setting the transmission component 8, not only is the working efficiency of the anti-warping device improved, but the uniform distribution and precise control of the shaped parts 2 are also ensured, thereby solving the transmission and distribution problems of the shaped parts 2 in the anti-warping device of the back contact battery 12. Compared with the prior art, the technical solution of this application, by introducing the transmission component 8, realizes the coordinated control of multiple shaped parts 2, significantly improving the anti-warping effect and production efficiency.

[0050] In some embodiments of this utility model, such as Figures 1-3As shown, the anti-warping device further includes: a mounting base 13, which is mounted on the transmission assembly 8 and moves with the transmission assembly 8; a fixing block 6, a plurality of fixing blocks 6 are evenly distributed along the extension direction of the mounting base 13, and the fixing block is provided with the sliding groove 61, the straight line of the sliding groove 61 intersecting the straight line of the extension direction of the mounting base 13; a first slider 7, the first slider 7 is disposed in the sliding groove 61 and reciprocates along the sliding groove 61; a first connecting rod 5, one end of the first connecting rod 5 is connected to the first slider 7, the bracket 1 is provided with a plurality of through holes, and the other end of the first connecting rod 5 passes through the through holes and connects to the molding part 2.

[0051] The design of the mounting base 13 allows the anti-warping device to move as a whole, following the movement of the transmission assembly 8, ensuring the mobility of the device. The fixing block 6 and the sliding groove 61 enable the first slider 7 to perform precise reciprocating motion along the sliding groove 61, thereby improving the accuracy of the movement. The first connecting rod 5 connects to the molding part 2 through a through hole on the bracket 1, ensuring the stable connection and precise control of the molding part 2.

[0052] Furthermore, the mounting base 13 can be made of metal to ensure its strength and durability. The fixing block 6 can be mounted on the mounting base 13 by bolts or other fixing devices to ensure its positional stability. The slide groove 61 can be designed as V-shaped or U-shaped to adapt to different motion requirements. The first slider 7 can be made of sliding bearings or other low-friction materials to reduce friction during movement. The first connecting rod 5 can be connected to the molded part 2 by threaded connection or other adjustable connection method to achieve precise adjustment of the position of the molded part 2.

[0053] Specifically, by adding the mounting base 13, the fixing block 6, the first slider 7, and the first connecting rod 5, precise control and improved stability of the anti-warping device are achieved. The mounting base 13 follows the transmission assembly 8 along its extension direction, thereby driving the first slider 7 along the extension direction of the slide groove 61. The straight line containing the extension direction of the transmission assembly 8 intersects the straight line containing the extension direction of the slide groove 61, causing the first connecting rod 5 connected to the first slider 7 to reciprocate in a direction perpendicular to the sliding assembly. Furthermore, this causes the molding part 2 to reciprocate in a direction perpendicular to the sliding assembly to perform anti-warping work.

[0054] In other words, through the cooperation of the anti-warping device and the transmission component 8, not only is the precise control and stability of the anti-warping device improved, but the problems of inaccurate control and poor stability in the prior art are also solved, thereby significantly improving the production efficiency and product quality of the back contact battery 12.

[0055] In some embodiments of this utility model, such as Figures 1-3 As shown, the anti-warping device further includes the first connector 9 and the second connector 10. The first connector 9 is installed on the end face of the mounting base 13 away from the transmission assembly 8, and the second connector 10 is installed on one end face of the first connector 9. The first connector 9 extends along a first direction until the output end of the motor 11 abuts against the second connector 10, and the output end of the motor 11 is connected to the second connector 10.

[0056] Specifically, the arrangement of the first connector 9 and the second connector 10 ensures effective connection and motion transmission between the output end of the motor 11 and the transmission assembly 8. The first connector 9 is mounted on the mounting base 13, and the second connector 10 is mounted on one end of the first connector 9. This structural design allows the output end of the motor 11 to extend along a first direction and be tightly connected to the second connector 10, thereby ensuring that the motor 11 can accurately drive the transmission assembly 8, and thus drive the multiple shaping parts 2 to perform anti-warping shaping. As a preferred embodiment, the first connector 9 can be made of metal to improve its strength and durability, while the second connector 10 can be a structural component that matches the output end of the motor 11, such as a bearing sleeve, to ensure the stability and accuracy of the connection.

[0057] In other words, the arrangement of the first connector 9 and the second connector 10 improves the stability and precision of the connection, ensures the overall motion coordination of the anti-warping device, and effectively solves the connection and motion transmission problems between the motor 11 and the transmission assembly 8. Compared with the prior art, this application, through the arrangement of the first connector 9 and the second connector 10, makes the connection between the output end of the motor 11 and the transmission assembly 8 more robust and the motion transmission more precise, thereby improving the working efficiency and stability of the anti-warping device. Moreover, the arrangement of the first connector 9 and the second connector 10 changes the transmission direction of the motor 11, thus making the overall structure of the anti-warping mechanism with back contact with the battery more compact.

[0058] In some embodiments of this utility model, the control accuracy a of the motor 11 satisfies: a≤0.05mm, and the anti-bend distance l of the motor 11 satisfies: 0mm≤l≤20mm.

[0059] Specifically, the control precision α of the motor 11, ≤0.05mm, ensures the accuracy of the anti-warping operation, avoiding excessive or insufficient anti-warping, thereby improving the quality and production efficiency of the battery 12. The anti-warping distance of the motor 11, between 0mm and 20mm, ensures the flexibility and adaptability of the anti-warping operation, allowing adjustment according to different warping conditions of the battery 12, further improving the anti-warping effect. In a preferred embodiment, the motor 11 can achieve a control precision α ≤ 0.05mm through a high-precision servo control system, while the anti-warping distance l of the motor 11 can be adjusted by changing the stroke of the motor 11.

[0060] In other words, by setting the control precision 'a' of the motor 11 to ≤ 0.05 mm and the anti-bending distance 'l' of the motor 11 to between 0 mm and 20 mm, precise control and efficient operation of the back contact battery 12 during the anti-bending process are ensured, solving the battery 12 warping problem and improving production efficiency and battery 12 quality. Compared with the prior art, the technical solution of this application significantly improves the accuracy and flexibility of the anti-bending operation by precisely controlling the anti-bending distance and control precision of the motor 11, thereby effectively solving the battery 12 warping problem and improving the production efficiency and quality of the battery 12.

[0061] In some embodiments of this utility model, such as Figure 5 As shown in A, the molding part 2 is configured as a polygonal block structure, the molding width b satisfies: 0mm<b≤700mm, and the molding angle α satisfies: 90°≤α≤180°.

[0062] Specifically, the polygonal block structure of the molded part 2 can be achieved in various ways. For example, the molded part 2 can be made of high-strength, high-temperature-resistant materials, such as stainless steel or ceramic, to ensure stability and durability during the anti-warping process. Furthermore, the shape and size of the molded part 2 can be precisely controlled using CNC machining technology to meet different molding requirements. In addition, the angle α of the molded part 2 can be finely adjusted using a mechanical adjustment device to adapt to different anti-warping requirements.

[0063] In other words, by setting the shaping width and shaping angle, the shape and size of the shaped part 2 can be precisely controlled, thereby effectively solving the problem of inconsistency in shape and size that may occur in the back contact battery 12 during the shaping process. This design ensures the accuracy and consistency of the shaped part 2 during the anti-warping process, improving the production quality and efficiency of the back contact battery 12. Compared with the prior art, the technical solution of this application significantly improves the accuracy and stability of the anti-warping process by precisely controlling the shape and size of the shaped part 2, reducing the defect rate in production and lowering production costs.

[0064] It should be noted that the shaping width b of the molded part 2 can be set to any value greater than 0 mm and less than or equal to 700 mm, such as 1 mm, 2 mm, 5 mm, 20 mm, 50 mm, 70 mm, etc. The shaping width of the molded part 2 is set according to actual production needs, and will not be elaborated here. The shaping angle α of the molded part 2 can be set to any angle greater than or equal to 90° and less than or equal to 180°, such as 90°, 105°, 130°, 150°, 180°, etc. The shaping angle α of the molded part 2 is set according to actual production needs, and will not be elaborated here.

[0065] In some embodiments of this utility model, such as Figure 5 As shown in B, the plastic part 2 is configured as a circular plastic block structure, and the diameter d of the circle satisfies: 0mm<d≤900mm.

[0066] Specifically, the molding component 2 adopts a circular molding block structure with a diameter ranging from 0mm to 900mm, and the diameter of the circle is not equal to 0mm. This design allows the molding component 2 to adapt to batteries 12 of different sizes when processing the back contact battery 12, thereby achieving a precise molding effect. Through this flexible size design, the molding component 2 can effectively solve the problem of different size requirements that may be encountered in the molding process of the back contact battery 12, ensuring that the molding component 2 can cover the battery 12 sizes from the smallest to the largest, improving production efficiency and product quality.

[0067] The diameter of the circular molded block structure is set to range from 0 mm to 900 mm. This range is chosen based on the diverse sizes of the back contact battery 12. Specific implementation methods may include using an adjustable-diameter mold or a modular design, allowing the diameter of the molded part 2 to be adjusted as needed. As a preferred embodiment, the diameter of the molded part 2 can be precisely controlled by a mechanical adjustment device to ensure ideal molding results are achieved on batteries 12 of different sizes.

[0068] Therefore, by adopting a circular molding block structure with a diameter ranging from 0mm to 900mm, the technical solution of this application can effectively solve the problem of different size requirements that may be encountered during the molding process of the back contact battery 12. Compared with the prior art, the technical solution of this application has higher flexibility and adaptability, and can significantly improve production efficiency and product quality.

[0069] In some embodiments of this utility model, such as Figure 5 As shown in C, the shaped part 2 is configured as an elliptical block structure.

[0070] Specifically, the elliptical block-shaped molding component 2 can adapt to back contact batteries 12 of different shapes and sizes, providing more flexible molding options. For example, the elliptical design can better adapt to the surface variations of the battery 12 during the molding process, thereby effectively solving the problem of the back contact battery 12 requiring diverse shapes during molding. As a preferred embodiment, the elliptical block-shaped molding component 2 can further improve molding accuracy and efficiency by adjusting the ratio of its major and minor axes. The ratio of the major and minor axes of the elliptical block-shaped molding component 2 can be arbitrarily adjusted to adapt to back contact batteries 12 of different sizes.

[0071] In other words, the elliptical block-shaped molding component 2 not only solves the technical problem of diverse shapes for the molding component 2 of the back contact battery 12, but also improves the flexibility and adaptability of molding. Compared with the prior art, the technical solution of this application, by adopting the elliptical block-shaped molding component 2, can better adapt to back contact batteries 12 of different shapes and sizes, thereby providing more flexible choices during the molding process and effectively solving the problem that the back contact battery 12 needs diverse shapes during the molding process.

[0072] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
