Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a photovoltaic module curing fixture. Background Technology

[0002] In the prior art, in order to avoid the sidewalls of the frame blocking the light-receiving surface of the photovoltaic module and to reduce the problem of dust accumulation on the surface of the photovoltaic module, the sidewalls of the receiving grooves on the frame that are used to accommodate the photovoltaic laminates are usually removed from the light-receiving surface (the side of the positive electrode) of the photovoltaic laminates. This is commonly known as a frame without an A-side.

[0003] However, when photovoltaic modules are encapsulated without an A-side frame, the lack of a receiving slot sidewall causes several issues during the curing process. Firstly, the absence of an A-side makes the laminates prone to sinking under gravity when the modules are stacked, resulting in the laminates being slightly lower than the frame (h1), affecting the module's aesthetics and increasing the risk of module breakage during transportation. Secondly, gaps are more likely to form between the photovoltaic laminates and the frame, allowing moisture to easily penetrate and affecting the product's lifespan and appearance.

[0004] Currently, manufacturers often use a back-side-up curing method for traditional modules because the presence of an A-side prevents the laminate from being higher than the frame. However, for modules without an A-side, the short frame does not restrain the laminate, and the laminate tends to protrude slightly under gravity. If a front-side-up curing method is used, the laminate will sink slightly under gravity, thus becoming lower than the frame. Therefore, suppliers often use hard objects as padding. Because these hard objects are irregular, the produced modules often still have appearance abnormalities. Utility Model Content

[0005] Therefore, it is necessary to provide a photovoltaic module curing fixture to address the issue of appearance abnormalities caused by the current use of frameless A-side curing laminates.

[0006] The first aspect of this application provides a photovoltaic module curing fixture for fixing laminates without an A-side frame. The fixture includes a first assembly and a second assembly. The first assembly includes a first mating portion, and the second assembly includes a second mating portion. The first mating portion mates with the second mating portion, and the first mating portion extends to form a first limiting portion. The first limiting portion extends away from the first mating portion to wrap around the side of the frame. The second mating portion extends to form a second limiting portion. The first limiting portion has a fitting position so that when the first limiting portion and the second limiting portion are stacked, the end of the second limiting portion is adapted to abut against the fitting position.

[0007] In one embodiment, the inner corner connection between the first mating portion and the second limiting portion is rounded, and the inner corner connection between the second mating portion and the second limiting portion is rounded.

[0008] In one embodiment, the first limiting portion is perpendicular to the first mating portion, the second limiting portion is perpendicular to the second mating portion, and the opposing surfaces of the first mating portion and the second mating portion are parallel.

[0009] In one embodiment, the length of the first limiting portion exceeds the side length of the frame used to support the laminate, and the first limiting portion is adapted to support the laminate when the laminate is stacked face down.

[0010] In one embodiment, the end of the second limiting part is formed as an arc surface, and the contact surface of the fitting part is adapted to the end of the second limiting part being formed as an arc surface.

[0011] In one embodiment, the first mating portion is movably connected to the second mating portion, and the first mating portion and the second mating portion are adapted to move relative to each other.

[0012] In one embodiment, the connection ends of the first mating portion and the second mating portion are both formed as hook-shaped connection structures, and the connection ends of the first mating portion and the second mating portion are hooked together.

[0013] In one embodiment, the connecting end of the first mating part is connected to the second mating part via an elastic connector, and the connecting end of the second mating part is connected to the first mating part via an elastic connector.

[0014] In one embodiment, the maximum travel A of the first mating part and the second mating part in the hooked state is less than the minimum length B of the elastic connector after compression.

[0015] In one embodiment, the first mating portion and the second mating portion are fixedly connected to form an integral unit.

[0016] In the aforementioned photovoltaic module curing fixture, a first and a second assembly are used to adapt to existing modules, ensuring stable fixation of the modules and laminates during curing, transportation, and handling. This avoids potential issues such as laminate displacement or damage during these processes and ensures the module's appearance remains unaffected. Furthermore, the photovoltaic module curing fixture is simple and convenient to install with the modules. It is compatible with existing module designs, eliminating the need for redesign and ensuring compatibility. Simultaneously, the upper limit design of the first and second assemblies effectively fixes the laminates. A fitting position is provided on the first limit position, and the end of the second limit position is designed to embed into this fitting position, ensuring that module curing is not affected during stacking. Moreover, the design of this photovoltaic module curing fixture is adaptable to frames of different heights, accommodating modules of different specifications. Attached Figure Description

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. 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.

[0030] 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", "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.

[0031] 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.

[0032] 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.

[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] For ease of understanding, first refer to... Figure 1 The prior art describes a frame 1 and the laminate 2 supported thereon. The main body of the frame 1 is roughly "U"-shaped, with one edge extending upwards to form an "L"-shaped mounting position together with the top edge of the "U"-shaped frame 1, thus forming a frame 1 without an A-side. Silicone is provided on this "L"-shaped mounting position, and the laminate 2 can be placed on the silicone to complete the support of the frame 1 for the laminate 2. Here, the top edge extending from the frame 1 is defined as the first edge, and the bottom edge away from the laminate 2 is defined as the second edge. However, this type of frame 1 does not restrain the laminate 2. If a face-up curing method is used, the laminate 2 will sink slightly under gravity, becoming lower than the frame 1 (h1). Therefore, a rigid object is usually used as a shim, but because the rigid object is irregular, it often leads to appearance abnormalities in the produced components.

[0035] This application is proposed to overcome the problems in the prior art described above. The preferred embodiments according to this application are described in detail below with reference to the accompanying drawings.

[0036] This application provides a photovoltaic module curing fixture, which is used to fix the laminate 2 in conjunction with the frameless A-side 1. During curing, the laminate 2 is prevented from shifting by cooperating with the photovoltaic module curing fixture, thereby ensuring that the overall appearance of the module is not affected.

[0037] Specifically, such as Figure 2 and Figure 4As shown, the photovoltaic module curing fixture includes a first assembly 31 and a second assembly 32. The first assembly 31 includes a first mating part 311, and the second assembly 32 includes a second mating part 321. The first mating part 311 and the second mating part 321 are connected to realize the connection between the first assembly 31 and the second assembly 32. In addition, the first mating part 311 extends into a first limiting part 312, and the second limiting part 322 extends away from the first mating part 311 and wraps around the side of the frame 1. The second mating part 321 extends into a second limiting part 322, and the second limiting part 322 is provided with a fitting position 313. When multiple photovoltaic module curing fixtures are stacked, the first limiting part 312 of the first component 31 in the upper photovoltaic module curing fixture 3 overlaps with the second limiting part 322 of the second component 32 in the lower photovoltaic module curing fixture 3. At this time, the end of the second limiting part 322 can stop at the fitting position 313 provided on the first limiting part 312, thereby realizing the stacking of multi-layer photovoltaic curing modules. In addition, after the multi-layer photovoltaic curing modules are stacked, the first limiting part 312 and the second limiting part 322 of the adjacent photovoltaic curing modules are completely fitted together to ensure that there is no large gap between the first limiting part 312 and the second limiting part 322 after stacking, which would affect the stability of the multi-layer photovoltaic curing modules after stacking.

[0038] Furthermore, in order to adapt to the outer edge and corners of the frame 1, the inner corner connection between the first mating part 311 and the first limiting part 312 is rounded. Similarly, the inner corner connection between the second mating part 321 and the second limiting part 322 is also rounded, thereby adapting to the corner shapes of the frame 1 that contact the first fitting part 31 and the second fitting part 32. Of course, if the corners of the frame 1 that contact the first fitting part 31 and / or the second fitting part 32 are set as right angles or other shapes, then the inner corner connections between the first mating part 311 and the first limiting part 312, and between the second mating part 321 and the second limiting part 322 can also be adaptively adjusted to right angles or other matching shapes.

[0039] like Figure 2As shown, the first limiting part 312 extends from the first mating part 311, and the second limiting part 322 extends from the second mating part 321. In order to better fit the two edges of the frame 1, the first limiting part 312 and the second limiting part 322 are respectively set to be perpendicular to the first mating part 311 and the second mating part 321. At this time, the first limiting part 312 is suitable to contact the first edge of the frame 1 and is suitable to extend to contact the surface of the laminate 2. The second limiting part 322 is suitable to contact the second edge of the frame 1. Since the laminate 2 is placed horizontally on the frame 1 and the placed laminate 2 is parallel to the second edge of the frame 1, the opposite surfaces of the first limiting part 312 and the second limiting part 322 are set to be parallel to ensure that they can fit the laminate 2 and the frame 1. Alternatively, if the mounting position on the frame 1 for placing the laminate 2 is set as an inclined surface so that the laminate 2 is not parallel to the second edge of the frame 1 after being placed on the frame 1, the angle of the first limiting part 312 and the second limiting part 322 can be adjusted according to the actual situation to ensure that the contact surface of the first limiting part 312 and the second limiting part 322 can be adapted to the installed laminate 2 and the frame 1.

[0040] Furthermore, the first limiting portion 312 extends out to the first mating portion 311 so as to at least cover the first edge of the frame 1. On this basis, the first limiting portion 312 continues to extend away from the first mating portion 311 until the length of the first limiting portion 312 exceeds the side length of the frame 1 used to support the laminate 2. When the laminate 2 is stacked face down, the first limiting portion 312 is adapted to serve as a support member of the laminate 2 at the bottom to support the laminate 2.

[0041] In some embodiments, since the end of the second limiting part 322 needs to be embedded in the fitting position 313 opened on the first limiting part 312, in order to avoid the end of the second limiting part 322 from being damaged by a large impact on the fitting position 313 during the stacking process, the end of the second limiting part 322 is formed as an arc surface, and the contact surface of the fitting position 313 matching the end of the second limiting part 322 is also provided as an arc surface, thereby dispersing the stress generated when the end of the second limiting part 322 and the fitting position 313 are docked, reducing the possibility of the end of the second limiting part 322 and the fitting position 313 being damaged under a large impact force when docking.

[0042] Therefore, by setting the first assembly 31 and the second assembly 32 to adapt to the existing frame 1 design, the frame 1 and the laminate 2 are stably fixed during curing, transportation, and handling, avoiding possible displacement or damage of the laminate 2 during the above processes, and ensuring that the appearance of the module is not affected. In addition, the photovoltaic module curing fixture 3 is simple and convenient to install with the frame 1 and the laminate 2. The photovoltaic module curing fixture 3 can adapt to the existing frame 1 design, so there is no need to redesign the existing frame 1, ensuring the compatibility with the existing frame 1 and saving the cost required for redesigning the frame. At the same time, the design of the first limiting part 311 and the second limiting part 321 on the first assembly 31 and the second assembly 32 can effectively fix the laminate 2. Furthermore, by setting the fitting part 313 on the first limiting part 312 and the end of the second limiting part 322 being designed to be able to fit into the fitting part, the curing of the module is not affected when the multi-layer photovoltaic module curing fixture 3 is stacked.

[0043] In some alternative embodiments, such as Figure 2 As shown, the first mating part 311 and the second mating part 321 are movably connected, allowing them to move relative to each other. Simultaneously, the movement of the first mating part 311 and the second mating part 321 drives the connected first limiting part 312 and the second limiting part 322 to move synchronously, thereby adjusting the distance between the first limiting part 312 and the second limiting part 322. In this example, it can adapt to frame heights of 30mm, 33mm, and 35mm. Therefore, the design of this photovoltaic module curing fixture 4 is adaptable to frame heights of different specifications, meeting the needs of different application scenarios.

[0044] Specifically, the connection ends of the first mating part 311 and the second mating part 321 can both be formed as hook-shaped connection structures 33. The hook-shaped connection structure 33 is formed by opening a slot in the middle section of the first mating part 311 and the second mating part 321. In order to realize the connection method of mutual hooking, the slot is opened on both sides of the middle section of the first mating part 311 and the second mating part 321. A groove is opened on the side wall away from the first limiting part 312 or the second limiting part 322 of the slot, so as to form a hook-shaped connection structure 33 suitable for mutual hooking on the first mating part 311 and the second mating part 321. The hook-shaped connection structure 33 can be specifically set as "U" shape. Furthermore, by directly adding the hook-shaped connection structure 33 to the first mating part 311 and the second mating part 321, the method of directly machining the hook-shaped connection structure 33 on the basis of the first mating part 311 and the second mating part 321 avoids the increase in tooling size that may be caused by adding other types of connection structures.

[0045] More specifically, the connecting end of the first mating part 311 is connected to the second mating part 321 via the elastic connector 34, and the connecting end of the second mating part 321 is connected to the first mating part 311 via the elastic connector 34. The connection method of the first mating part 311 and the second mating part 321 will be described in detail below. Specifically, one end of the elastic connector 34 is connected to one side wall of the slot formed in the middle section of the first mating part 311, and this side wall of the slot is the side wall near the first limiting part 312. The other end of the elastic connector 34 is connected to the end face of the connecting end of the second mating part 321 opposite to this slot side wall. Similarly, one end of the elastic connector 34 is connected to one side wall of the slot formed in the middle section of the second mating part 321, and this side wall of the slot is the side wall near the second limiting part 322. The other end of the elastic connector 34 is connected to the end face of the connecting end of the first mating part 311 opposite to this slot side wall. The elastic connector 34 can be a spring. Because the hook-shaped connection structure 33 is U-shaped, when the connecting ends of the first mating part 311 and the second mating part 321 are hooked together, the first mating part 311 and the second mating part 321 can smoothly move closer or further apart without interference between their connecting ends. Furthermore, after the first mating part 311 and the second mating part 321 are hooked together, the width of the hook point remains consistent with the widths of both parts, without any noticeable protrusion.

[0046] Furthermore, the connection ends of the first mating part 311 and the second mating part 321 can still move relative to each other while in a hooked state. In order to prevent the hook-shaped connection structure 33 of the first mating part 311 and the second mating part 321 from disengaging due to excessive compression of the elastic connecting member 34 connected to the first mating part 311 and the second mating part 321, the maximum stroke A of the first mating part 311 and the second mating part 321 should be set to be less than the minimum length B of the elastic connecting member 34 after compression. For example, if the relative movement distance between the first mating part 311 and the second mating part 321 is greater than or equal to 10cm, they will disengage. Therefore, it is necessary to ensure that the maximum movement stroke A of the first mating part 311 and the second mating part 321 is less than 10cm. In this case, an elastic connector 34 with a minimum length B ≥ 10cm after compression can be used to ensure that the relative movement distance between the first mating part 311 and the second mating part 321 never exceeds 10cm, thereby preventing the hook-like connection structure 33 of the first mating part 311 and the second mating part 321 from disengaging during the movement.

[0047] In an optional embodiment, such as Figure 5As shown, the first mating part 311 of the first assembly 31 and the second mating part 321 of the second assembly 32 can also be fixedly connected to form a whole. With this connection method, the first mating part 311 and the second mating part 321 can no longer move relative to each other, and therefore, the distance between the first limiting part 312 and the second limiting part 322 cannot be adjusted.

[0048] Therefore, the photovoltaic module fixing fixture formed by connecting the first assembly 31 and the second assembly 32 can be adapted to a frame 1 of a fixed size, but not to a frame 1 of other specifications. Furthermore, since the first assembly 31 and the second assembly 32 are fixedly connected, the combination of the elastic connector 34 and the hook-shaped connecting structure 33 is no longer needed to adjust the distance between the first limiting part 312 and the second limiting part 322, thus eliminating the need for distance adjustment via the elastic connector 34 and the hook-shaped connecting structure 33. Moreover, the fixed connection significantly improves the overall rigidity. Additionally, since the formed photovoltaic module fixing fixture can be adapted to a frame 1 of a specific specification, a dedicated fixture system with a clear dimensional correspondence can be formed between the photovoltaic module fixing fixture and the frame 1 of that specific specification. Therefore, this embodiment sacrifices versatility for structural stability, making it particularly suitable for photovoltaic module installation scenarios with high standardization, good batch consistency, and low frequency of specification changes.

[0049] 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.

[0050] 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.
