Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation, and in particular to a tooling and a photovoltaic assembly. Background Art

[0002] During the production of photovoltaic modules, there are often modules without an A-side that need to be assembled. During the assembly process, these modules without an A-side must go through a curing process. During this curing process, the laminate loses the support of the frame. Before the laminate and the frame are fully cured, the laminate will deform under the influence of gravity, sagging in the middle and separating from the frame.

[0003] In the related art, although there are also toolings for fixing components without A-side, the toolings are usually at least 1m long and made of hard plastic, which cannot provide support for the laminates and cannot effectively prevent the laminates from detaching from the frame. Utility Model Content

In addition, the terms "first", "second", "third" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0028] In addition, the terms "horizontal", "vertical" and the like do not mean that the components must be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0029] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] The present application provides a tooling to solve the problem in the related art that the tooling cannot provide sufficient supporting force for the laminate when fixing the component without A-side, resulting in the laminate being easily separated from the frame.

[0031] Photovoltaic modules typically consist of a laminate and a frame, with the frame typically being a gate-shaped frame within which the laminate is mounted. When the frame is reduced to one side, i.e., when the frame changes from a gate shape to an L-shape, it is referred to as an A-free frame. Accordingly, a photovoltaic module assembled without an A-free frame is also referred to as an A-free module.

[0032] During the assembly process, components without an A-side require a curing process to securely connect the frame to the laminate. During this curing process, due to process requirements, the frame without the A-side is usually placed face-down, vertically facing downward. This removes the support provided by the frame, and before the laminate and frame are fully cured, gravity can cause the laminate to deform, causing the center portion to sag and separate from the frame.

[0033] See also Figure 1 、 Figure 2 A tooling is provided for fixing a component without an A-surface. The tooling includes a tooling body 100, which includes a fixing portion 110 and a push portion 120. The push portion 120 is provided on the fixing portion 110. Two push portions 120 are provided, and the two push portions 120 are symmetrically arranged on the fixing portion 110. The push portions 120 are arranged at an angle, and each push portion 120 is inclined toward the direction of the other push portion 120.

[0034] Specifically, when using this embodiment to secure a component without an A-surface, the fixing portion 110 of the tool body 100 is placed against the frame of the component without an A-surface, and the pushing portion 120 of the tool body 100 is placed against the laminate of the component without an A-surface. Since two pushing portions 120 are provided in this embodiment, and each pushing portion 120 is tilted toward the other pushing portion 120, after this embodiment is installed on the component without an A-surface, the two pushing portions 120 are pressed against either side of the laminate, cooperating with the fixing portion 110 to press and secure the laminate to the frame, providing support for the laminate and preventing the laminate from deforming under the action of gravity and separating from the frame.

[0035] In some embodiments, for example, Figure 1 、 Figure 2 As shown, the fixing portion 110 is configured as a rectangular plate, and the two push portions 120 are both disposed at the edges of the fixing portion 110. The push portions 120 are disposed at the edges of the fixing portion 110, which ensures that when this embodiment is attached to a component without an A-surface, the fixing portion 110 abuts against the frame while the push portions 120 abut against the laminate, thereby ensuring that this embodiment can properly provide support for the laminate and improving the reliability of the operation of this embodiment.

[0036] In some embodiments, for example, Figure 1 、 Figure 2 As shown, the push portion 120 is configured as a rectangular plate, with the long side of the push portion 120 connected to the long side of the fixing portion 110. The fixing portion 110 and the push portion 120 are both configured as rectangles, making the overall shape of this embodiment more regular, thereby better cooperating with the non-A-surface component and making this embodiment more convenient to use. The push portion 120 and the fixing portion 110 are both connected to each other via their long sides, which enables this embodiment to provide a longer support length after being snapped onto the non-A-surface component, ensuring that this embodiment provides more reliable and stable support for the laminate.

[0037] In some embodiments, for example, Figure 1 、 Figure 2 As shown, the push portion 120 and the fixing portion 110 are both made of polycarbonate. Polycarbonate is a high-performance thermoplastic engineering plastic. It has high transparency, impact resistance, heat resistance, flame retardancy and high mechanical strength, and is a commonly used material in many fields. In this embodiment, the push portion 120 and the fixing portion 110 are made of polycarbonate. On the one hand, this embodiment can have sufficient strength to provide support for the laminate. On the other hand, this embodiment is transparent as a whole, and the snap-in position can be accurately found when using this embodiment, making it more convenient to use.

[0038] It should be noted that polycarbonate is easy to process and can be processed through various methods such as injection molding, extrusion, and blow molding. This makes this embodiment easy to produce and reduces the production and processing difficulty of this embodiment. Polycarbonate also has good weather resistance and can be used in outdoor environments for a long time. This ensures that this embodiment has a long service life after being used in photovoltaic modules and is not easily subject to wear and tear in outdoor environments. Furthermore, when this embodiment is in use, the push portion 120 will directly abut the laminate. However, polycarbonate, as a thermoplastic engineering plastic, will not cause scratches or marring on the outer surface of the laminate, further ensuring the practicality of this embodiment.

[0039] In some embodiments, for example, Figure 1 、 Figure 2 As shown, the thickness of the fixing portion 110 is L1, and the thickness of the pushing portion 120 is L2, satisfying the following: L1 = L2 ≤ 2.9 mm. The thickness of the fixing portion 110 and the pushing portion 120 are limited to provide sufficient support for the laminate and prevent deformation of the laminate, while ensuring that this embodiment does not interfere with the assembly of the frame and the laminate.

[0040] Since this embodiment is made of polycarbonate, the commonly used thickness specifications of polycarbonate are 2mm, 2.5mm, and 3mm. In this embodiment, in order to prevent the push portion 120 from interfering with the laminate, the thickness of the tooling needs to be less than 2.9mm. Therefore, for ease of production and processing, a 2.5mm thick polycarbonate can be selected. While ensuring that this embodiment does not interfere with the laminate, it can also provide sufficient support for the laminate, ensuring the supporting effect of this embodiment on the laminate and preventing the laminate from separating from the frame.

[0041] In addition, the use of polycarbonate with a thickness of 2.5 mm as the raw material can make the raw materials for the production of this embodiment easy to obtain, further reducing the production and processing difficulty of this embodiment.

[0042] In some embodiments, for example, Figure 1 、 Figure 2 As shown, the length of the fixing portion 110 is L3, and the length of the pushing portion 120 is L4, satisfying: L3 = L4 ≥ 100mm. The lengths of the fixing portion 110 and the pushing portion 120 are the same, ensuring that this embodiment can simultaneously abut against the frame and the laminate, fixing the laminate and the frame, making this embodiment easier to use. Specifically, the overall length of this embodiment is limited, and it is more appropriate to set the overall length of this embodiment to 100mm. This allows this embodiment to provide sufficient support for the component without A-side while maintaining flexibility and convenience in use.

[0043] If the overall length of this embodiment is less than 100 mm, it will not be able to provide sufficient support for the laminate. Although multiple tooling of this embodiment can be set on the side without the A-side component to ensure that this embodiment can provide sufficient support, the increase in the number of this embodiment will increase the workload of the operator and reduce the convenience of using this embodiment.

[0044] If the overall length of the present embodiment is greater than 100mm, such as setting the overall length of the present embodiment to 150mm or 200mm, on the one hand, the present embodiment uses polycarbonate as the material, and the length is too long, which may cause the present embodiment itself to deform, affecting the support effect of the present embodiment; on the other hand, the length is too long, which will affect the convenience of the present embodiment when in use. Setting the length to 100mm can also make the present embodiment more suitable for the production line without A-side components. For example, when the length of one side of the non-A-side component is 300, two of the present embodiments with a length of 100mm can be selected to provide support and fixing force for the laminate and frame of the non-A-side component, ensure reliable support, avoid deformation of the laminate, and clamp the two fixtures, and the operation will not be too cumbersome. If the length of the present embodiment is 150mm or 200mm, only a single fixture of the present embodiment can be set on the side, and the support effect is relatively weak.

[0045] It is understandable that the overall length of the tooling of this embodiment can be adaptively adjusted according to the different side lengths of the non-A-surface component, as long as it can ensure that this embodiment can provide sufficient support strength and be easy to use.

[0046] Of course, when in use, if the side length of the non-A-surface component is longer, multiple tooling of this embodiment can be set at the edge of the non-A-surface component according to actual conditions to ensure the fixing effect of this embodiment on the frame and the laminate.

[0047] In some embodiments, for example, Figure 1 、 Figure 2 As shown, a clamping end 121 is provided on the push portion 120 away from the fixing portion 110. The two clamping ends 121 are located in the same horizontal plane, and the distance between the two clamping ends 121 is L5, satisfying L5 ≤ 27.1 mm. The thickness of the non-A-surface component is typically set to 27.1 mm. The distance between the two clamping ends 121 is less than the thickness of the non-A-surface component, ensuring that both push portions 120 abut against the laminate, providing support for the laminate.

[0048] It should be noted that the smaller the distance between the two clamping ends 121, the greater the force exerted by the push portion 120 on the laminate, and the more reliable the fixation between the frame and the laminate in this embodiment. Correspondingly, if the distance between the two clamping ends 121 is too small, the push portion 120 may exert too much pressure on the laminate, which may also cause damage to the laminate. For example, in this embodiment, the distance between the two clamping ends 121 is set to 20 mm, so that this embodiment can provide sufficient support for the laminate and the frame, ensuring the reliability of the fixation between the two, while also avoiding damage to the laminate in this embodiment, ensuring the practicality of this embodiment.

[0049] In some embodiments, for example, Figure 1 、 Figure 2 As shown, the distance between the clamping end 121 and the fixing portion 110 in the vertical direction is L6, which satisfies: L6 ≥ 30 mm. The distance between the clamping end 121 and the fixing portion 110, that is, the distance that the laminate and the frame extend into the fixture after the fixture of this embodiment is clamped on the component without A-surface, the greater the distance, the more reliable the support and fixing effect provided by the fixture of this embodiment. Exemplarily, the distance between the clamping end 121 and the fixing portion 110 is set to 30 mm, which enables the fixture of this embodiment to provide sufficient support for the frame and the laminate, while also ensuring that the installation or disassembly process of this embodiment is simple and convenient.

[0050] In some embodiments, for example, Figure 1 、 Figure 2 As shown, the non-A-surface assembly includes a laminate and a frame, and the frame is installed at the edge of the laminate. When the tooling body 100 is installed on the non-A-surface assembly, the fixing portion 110 abuts against the frame, and the pushing portion 120 abuts against the laminate. In this way, it is possible to ensure that the frame and the laminate are reliably fixed in this embodiment. Specifically, the tooling of this embodiment provides support for the laminate, preventing the laminate from being affected by gravity and sagging to the point of separation from the frame, thereby preventing the laminate from sagging and avoiding the risk of falling out of the frame.

[0051] The present invention also provides a photovoltaic assembly, comprising an A-side-free assembly and the tooling of any one of the above embodiments, wherein the tooling can be installed on the A-side-free assembly to clamp and fix the frame and laminate of the A-side-free assembly.

[0052] Among them, the assembly process of photovoltaic modules includes:

[0053] After the frame is assembled on the laminate, the tooling is installed on the edge of the component without the A-side.

[0054] The fixing portion 110 abuts against the frame of the component without the A-surface, and the pushing portion 120 abuts against the laminated component without the A-surface.

[0055] Tooling is installed on each edge of the component without A-side. After installation, the tooling and the component without A-side enter the curing room together to perform curing operations on the component without A-side.

[0056] After the curing operation is completed, the components without A-side and the tooling enter the cleaning process together, and the tooling is removed during the cleaning process and reserved for next use.

[0057] It should be noted that before the non-A-side assembly enters the curing room, adhesive is sprayed between the frame and the laminate. Because the laminate and frame are restrained by the tooling, they do not move relative to each other, and the laminate does not fall out of the frame, ensuring a uniform thickness of the adhesive sprayed between the frame and the laminate. After entering the curing room, the adhesive is cured, thus completing a fixed connection between the frame and the laminate.

[0058] In the subsequent cleaning process, the tooling can be directly removed. In addition, if the tooling is stained with adhesive, the tooling can be cleaned during the cleaning process so that it can be used next time.

[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
