Description

Technical Field

[0001] This application relates to the field of photovoltaic module lamination technology, and in particular to lamination auxiliary devices and lamination equipment. Background Technology

[0002] In the production of photovoltaic (PV) modules, lamination is a crucial step, and its quality directly impacts the module's performance. To improve lamination yield and reduce defects such as bubbles and cracks, a lamination frame is typically used around the PV module to assist in the lamination process. However, with the diversification of PV module designs, different sizes of lamination frames are needed for different module specifications, increasing costs. Utility Model Content

[0003] Therefore, it is necessary to provide a lamination auxiliary device and lamination equipment to address the issue of increased costs caused by the need to prepare lamination frames of different sizes for photovoltaic modules of different specifications.

[0004] In a first aspect, this application provides a lamination assist device, comprising:

[0005] A base plate, the base plate including a bearing surface for supporting photovoltaic modules;

[0006] Multiple lamination auxiliary mechanisms are provided, all of which are disposed on the bearing surface and are configured to correspond one-to-one with each edge of the photovoltaic module. Each lamination auxiliary mechanism includes a mounting base, a telescopic member, and a laminating member. The telescopic member is disposed on the mounting base and connected to the laminating member. The telescopic member has a retracted state that is at least partially retracted into the mounting base and an extended state that extends out of the mounting base. When the telescopic members of all lamination auxiliary mechanisms are in the extended state, all the laminating members can be combined to form a lamination frame for fitting over the photovoltaic module.

[0007] The technical solution will be further explained below:

[0008] In one embodiment, the bearing surface is provided with multiple mounting slots, and the lamination auxiliary mechanism is installed in each of the mounting slots in a corresponding manner.

[0009] In one embodiment, the lamination auxiliary mechanism further includes a lifting member disposed at the bottom of the mounting groove and connected to the mounting base. The lifting member is used to drive the mounting base to rise and fall, so that the mounting base and the laminating member are received in the mounting groove or extend out of the mounting groove.

[0010] In one embodiment, when the mounting base and the laminate are housed in the mounting groove, the top surface of both the mounting base and the top surface of the laminate are flush with the bearing surface.

[0011] In one embodiment, each lamination auxiliary mechanism includes multiple lifting components arranged at intervals along the mounting base.

[0012] In one embodiment, the laminate is used to abut against the edge of the corresponding photovoltaic module, and the length of the laminate is equal to the length of the edge of the corresponding photovoltaic module.

[0013] In one embodiment, both ends of the laminate are provided with bevels, and when all the telescopic components of the lamination auxiliary mechanism are in the extended state, the bevels of two adjacent laminates meet to form a right-angle structure.

[0014] In one embodiment, each of the lamination aids includes a plurality of telescopic members arranged at intervals along the lamination member.

[0015] In one embodiment, the base plate is a heating plate used to heat the photovoltaic module.

[0016] Secondly, this application also provides a lamination apparatus, including the aforementioned lamination auxiliary device.

[0017] When the aforementioned lamination auxiliary device is in operation, the photovoltaic module is first transported or placed on the bearing surface of the substrate. Then, the telescopic components of each lamination auxiliary mechanism extend to their extended state, driving the laminating components to press against the edge of the photovoltaic module. This causes all the laminating components to collectively enclose and fit within a lamination frame surrounding the photovoltaic module. This lamination frame supports the edge of the photovoltaic module, effectively improving the lamination effect and reducing defects such as bubbles and cracks that occur during the lamination process. Furthermore, compared to traditional fixed-size lamination frames, the lamination auxiliary device of this application uses multiple telescopic laminating components to form a lamination frame. Therefore, when dealing with photovoltaic modules of different sizes, only different lengths of laminating components need to be replaced, and the positions of the laminating components can be adjusted using the telescopic components to obtain lamination frames of different sizes to accommodate photovoltaic modules of different specifications. Thus, there is no need to replace the entire device, making the operation flexible, efficient, and effectively reducing costs. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] 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.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] One embodiment of this application provides a lamination auxiliary device for assisting photovoltaic module 30 in the lamination process. See [link to relevant documentation]. Figure 1 as well as Figure 2 Specifically, one embodiment of the lamination auxiliary device includes a base plate 10 and a plurality of lamination auxiliary mechanisms. The base plate 10 includes a bearing surface for supporting the photovoltaic module 30. All lamination auxiliary mechanisms are disposed on the bearing surface and are configured to correspond one-to-one with each edge of the photovoltaic module 30. Each lamination auxiliary mechanism 20 includes a mounting base 21, a telescopic member 23, and a laminating member 22. The telescopic member 23 is disposed on the mounting base 21 and connected to the laminating member 22. The telescopic member 23 has a retracted state that is at least partially retracted into the mounting base 21 and an extended state that extends out of the mounting base 21. When the telescopic members 23 of all lamination auxiliary mechanisms 20 are in the extended state, the laminating members 22 of all lamination auxiliary mechanisms 20 can be together to form a lamination frame for sleeved on the photovoltaic module 30.

[0035] Specifically, when the aforementioned lamination auxiliary device is in operation, the photovoltaic module 30 is first transported or placed on the bearing surface of the base plate 10. Then, the telescopic members 23 of each lamination auxiliary mechanism 20 extend to the extended state, driving the laminating members 22 to press against the edge of the photovoltaic module 30. This allows all the laminating members to collectively enclose and fit a lamination frame around the photovoltaic module 30. By using the lamination frame to support the edge of the photovoltaic module 30, the lamination effect can be effectively improved, reducing defects such as bubbles and cracks in the photovoltaic module 30 during the lamination process. Furthermore, compared to traditional lamination frames with fixed dimensions, the lamination auxiliary device of this application uses multiple telescopic laminating members 22 to collectively enclose and form a lamination frame. Therefore, when dealing with photovoltaic modules 30 of different sizes, only the laminating members 22 of different lengths need to be replaced, and the position of the laminating members 22 can be adjusted using the telescopic members 23 to obtain lamination frames of different sizes to fit photovoltaic modules 30 of different sizes. Thus, there is no need to replace the entire device, making the operation flexible and efficient, and effectively reducing costs.

[0036] See Figure 3In some embodiments, the bearing surface is provided with multiple mounting slots 11, and the lamination auxiliary mechanism 20 is installed in the mounting slots 11 one by one. By installing the lamination auxiliary mechanism 20 in the mounting slots 11 one by one, the overall structure of the lamination auxiliary device is more reasonable and compact, avoiding the lamination auxiliary device from being too large.

[0037] See Figure 2 For example, in some embodiments, the lamination auxiliary mechanism 20 further includes a lifting member 24, which is disposed at the bottom of the mounting groove 11 and connected to the mounting base 21. The lifting member 24 is used to drive the mounting base 21 to rise and fall so that the mounting base 21 and the laminating member 22 are received in the mounting groove 11 or extend out of the mounting groove 11.

[0038] See Figure 4 as well as Figure 5 Specifically, during the transport of the photovoltaic module 30, the lifting component 24 drives the mounting base 21 and the laminating component 22 to be housed in the mounting groove 11 to avoid interference between the mounting base 21 and the laminating component 22 and the photovoltaic module 30 being transported. When the photovoltaic module 30 is transported to a designated position on the bottom plate 10, the lifting component 24 drives the mounting base 21 to rise, so that the mounting base 21 and the laminating component 22 extend out of the mounting groove 11. The telescopic component 23 then drives the laminating component 22 to abut against the edge of the photovoltaic module 30, so that all the laminating components 22 together enclose and form a laminated frame.

[0039] See Figure 5 Optionally, in one embodiment, when the mounting base 21 and the laminate 22 are housed in the mounting groove 11, the top surfaces of both the mounting base 21 and the laminate 22 are flush with the bearing surface. This ensures that the photovoltaic module 30 can be transported more smoothly onto the base plate 10, preventing the mounting base 21 and the laminate 22 from protruding and obstructing the photovoltaic module 30.

[0040] Understandably, in other embodiments, when the mounting base 21 and the laminate 22 are housed in the mounting groove 11, the top surface of the mounting base 21 and the top surface of the laminate 22 may also be lower than the bearing surface.

[0041] See Figure 2 For example, in one embodiment, each lamination auxiliary mechanism 20 includes a plurality of lifting members 24, which are spaced apart along the mounting base 21. By having the mounting base 21 be lifted and lowered together by the plurality of lifting members 24, the smoothness of the lifting and lowering of the mounting base 21 can be improved.

[0042] For example, the lifting member 24 can be an electric telescopic rod or a cylinder, without limitation.

[0043] See Figure 2In some embodiments, the laminate 22 is used to abut against the edge of the corresponding photovoltaic module 30, and the length of the laminate 22 is equal to the length of the edge of the corresponding photovoltaic module 30. This ensures that after the laminate 22 abuts against the edge of the corresponding photovoltaic module 30, it can completely cover the edge of the photovoltaic module 30, thus ensuring the lamination effect.

[0044] For example, the photovoltaic module 30 has two long sides and two short sides along its edge. The lamination aid device includes four lamination aid mechanisms 20, wherein two lamination aid mechanisms 20 correspond one-to-one with the two long sides of the photovoltaic module 30, and the length of the laminating element 22 of these two lamination aid mechanisms 20 is equal to the length of the long side of the photovoltaic module 30. The other two lamination aid mechanisms 20 correspond one-to-one with the two short sides of the photovoltaic module 30, and the length of the laminating element 22 of these two lamination aid mechanisms 20 is equal to the length of the short side of the photovoltaic module 30.

[0045] See Figure 5 In some embodiments, both ends of the laminate 22 are provided with chamfers 221, and when all the telescopic members 23 of the lamination auxiliary mechanisms 20 are in the extended state, the chamfers 221 of two adjacent laminates 22 meet to form a right angle structure. For example, the chamfers 221 on both ends of the laminate 22 are 45° angles, so that when all the telescopic members 23 of the lamination auxiliary mechanisms 20 are in the extended state, the chamfers 221 of two adjacent laminates 22 can meet to form a 90° right angle to adapt to the 90° angle of the rectangular photovoltaic module 30.

[0046] See Figure 2 In one embodiment, each lamination auxiliary mechanism 20 includes multiple telescopic members 23, which are spaced apart along the laminator 22. By having multiple telescopic members 23 jointly drive the laminator 22 to extend and retract, the smoothness of the extension and retraction of the laminator 22 can be improved. For example, the telescopic members 23 can be electrically operated telescopic rods.

[0047] In some embodiments, the base plate 10 is a heating plate used to heat the photovoltaic module 30. The base plate 10 can directly use a heating plate from an existing lamination apparatus. The heating plate in the lamination apparatus is used to heat the photovoltaic module 30 during the lamination process to melt the adhesive film in the photovoltaic module 30, thereby bonding the cell strings in the photovoltaic module 30 with the glass cover and the back sheet to form a whole.

[0048] This application provides a lamination apparatus. Specifically, one embodiment of the lamination apparatus includes the lamination auxiliary device of any of the above embodiments.

[0049] For example, in one embodiment, the base plate 10 of the lamination auxiliary device can be directly adopted as the heating plate used to heat the photovoltaic module 30 in the lamination equipment. Further, the heating plate in the lamination equipment is usually provided with a high-temperature cloth for conveying the photovoltaic module 30. In order to avoid interference between the lamination auxiliary device and the high-temperature cloth during the lifting and lowering process, a clearance groove for avoiding the lamination auxiliary device can be opened at the position of the high-temperature cloth corresponding to the lamination auxiliary device.

[0050] When the lamination equipment described above is working, the high-temperature cloth first conveys the photovoltaic module 30 to the bearing surface of the base plate 10. Then, the telescopic components 23 of each lamination auxiliary mechanism 20 extend to the extended state, driving the lamination components 22 to press against the edge of the photovoltaic module 30. This allows all the lamination components to jointly enclose and fit a lamination frame around the photovoltaic module 30. The lamination frame supports the edge of the photovoltaic module 30, effectively improving the lamination effect and reducing defects such as bubbles and cracks in the photovoltaic module 30 during the lamination process. Furthermore, compared to traditional lamination frames with fixed dimensions, the lamination auxiliary device of this application uses multiple telescopic lamination components 22 to jointly enclose and form a lamination frame. Therefore, when dealing with photovoltaic modules 30 of different sizes, only the lamination components 22 of different lengths need to be replaced, and the position of the lamination components 22 can be adjusted using the telescopic components 23 to obtain lamination frames of different sizes to fit photovoltaic modules 30 of different sizes. Therefore, there is no need to replace the entire device, making the operation flexible and efficient, and effectively reducing costs.

[0051] 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.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
