Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaics, in particular to a glue foaming device and glue spraying equipment. Background Art
[0002] A solar cell is a semiconductor device that directly converts solar energy into electricity. Currently, most common solar cells are in the form of sheets, also known as solar cells. A single solar cell has low power output and a limited lifespan in air, making it unsuitable for direct use. Therefore, multiple solar cells are typically further electrically connected, laminated, and packaged to form a photovoltaic module.
[0003] Photovoltaic modules consist of a laminate and a frame. The process of combining these components into a photovoltaic module typically requires the application of sealant, also known as gluing. The sealant connects the frame to the photovoltaic module and provides both sealing and cushioning. Traditionally, silicone sealant has been used. Silicone is a highly viscous, paste-like material that requires at least four hours to cure in a specific environment. This slow curing rate affects the production efficiency of photovoltaic modules.

They do not limit or imply that the device or element referred to must have a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit the implementation of this invention.

[0029] The present disclosure provides a rubber foaming device comprising a rubber container, a foaming element, and an air supply pipe. The rubber container has a foaming chamber, and a rubber inlet and outlet that are connected to the foaming chamber and disposed opposite to each other. The foaming element is disposed within the foaming chamber and is hollow and has at least one air hole. The air supply pipe is connected to the foaming element and communicates with the air hole in the foaming element.
[0030] It is understood that in actual use, the rubber material can enter the bubble chamber through the rubber inlet and then flow out through the rubber outlet, with the rubber material flowing along the rubber inlet toward the rubber outlet. A bubble member is provided in the bubble chamber, and the rubber material covers the bubble member. The bubble member has a hollow structure and is provided with air holes, so that the internal space of the bubble member is connected to the external bubble chamber. The gas input into the bubble member by the air supply pipe is discharged through the air holes and can be mixed into the flowing rubber material, thereby forming a microbubble structure in the rubber material. The rubber material with a microbubble structure has a larger contact area with the air during curing, thereby enabling faster curing.
[0031] Furthermore, the introduction of microbubbles into the rubber reduces its density, saving on actual rubber usage and thus reducing material costs. Furthermore, the microbubbles make the cured rubber fluffier and improve its elasticity, resulting in a better stress-buffering effect.
[0032] Figure 1 This is a schematic diagram of the structure of a rubber foaming device disclosed in the present invention. Figure 1As shown, the rubber foaming device includes a rubber container 100, a foaming element 110, and an air supply pipe 120. The rubber container 100 has a foaming chamber 103, and a glue inlet 101 and a glue outlet 102 that are connected to and opposite to the foaming chamber 103. The foaming element 110 is disposed within the foaming chamber 103. The foaming element 110 is hollow and has at least one air hole 1101 formed therein. The air supply pipe 120 is connected to the foaming element 110 and is connected to the air hole 1101.
[0033] In this embodiment, it is understood that the gas supply tube 120 is used to supply gas to the interior of the foaming element 110, and the gas hole 1101 is used to exhaust the gas inside the foaming element 110. Therefore, the gas hole 1101 should be located in an area of the foaming element 110 outside the connection point with the gas supply tube 120. The end of the gas supply tube 120 away from the foaming element 110 can be located outside the plastic container 100 to facilitate connection to an external gas source.
[0034] Reference Figure 1 As shown in some examples of this embodiment, the gas pipe 120 is provided through the wall of the bubble cavity 103, and one end of the gas pipe 120 is located outside the bubble cavity 103. The gas pipe 120 is connected to the bubble member 110, and the gas pipe 120 can be used to transport external gas into the bubble member 110. The bubble member 110 has a hollow structure and is provided with air holes 1101. The air holes 1101 can connect the internal space of the bubble member 110 with the external space. The bubble member 110 is used to introduce gas into the rubber material flowing through the bubble cavity 103. In actual use, the gas in the gas pipe 120 passes through the bubble member 110 and diffuses out from the air holes 1101 of the bubble member 110, and then merges into the rubber material in the bubble cavity 103.
[0035] As some examples of this embodiment, the foaming element 110 may be provided with one or more air holes 1101. If only one air hole 1101 is provided on the foaming element 110, the gas released from the air hole 1101 may not be evenly mixed into the rubber material, potentially resulting in poor foaming of the rubber material. Therefore, in this embodiment, the foaming element 110 may be provided with multiple air holes 1101 spaced apart, which can improve the foaming effect of the rubber material.
[0036] In order to facilitate understanding of the function of the foaming member 110 in this embodiment, Figure 2 for Figure 1 Schematic diagram of the structure of the foaming member 110 in the rubber foaming device. Figure 2As shown in some examples of this embodiment, the foaming element 110 may include multiple hollow air guides 111, each of which is connected to the air delivery pipe 120, and each of which is provided with at least one air hole 1101. The multiple air guides 111 can extend to more areas within the foaming cavity 103, which can make the air holes 1101 more evenly distributed, further improving the foaming effect of the rubber material.
[0037] It is understood that, in an actual structure, the communication method between the air guide portion 111 and the air supply pipe 120 can be selected from at least one of direct communication and indirect communication. For example, multiple air guide portions 111 are respectively connected to the air supply pipe 120, so that each air guide portion 111 is directly connected to the air supply pipe 120. Alternatively, one or more air guide portions 111 are connected to the air supply pipe 120 and are directly connected to the air supply pipe 120, and other air guide portions 111 are indirectly connected to the air supply pipe 120 through these air guide portions 111.
[0038] Further, refer to Figure 2 As shown, in this example, among the multiple air guides 111, each air guide 111 is connected and communicates with at least one other air guide 111. This ensures that the gas is fully delivered to each air guide 111 and maintains a substantially uniform gas pressure within each air guide 111. This results in a more uniform gas flow rate ejected from each air hole 1101, ensuring a more uniform distribution of the microbubble structure of the rubber material in each region of the bubble cavity 103.
[0039] Further, refer to Figure 2 As shown, in this example, the air guide portion 111 is in the shape of a hollow tube. Among the multiple air guide portions 111, at least two air guide portions 111 extend along a first direction, and the air guide portions 111 extending along the first direction are arranged side by side and spaced apart. At least two air guide portions 111 extend along a second direction intersecting with the first direction, and the air guide portions 111 extending along the second direction are arranged side by side and spaced apart. As an example, in Figure 2 In the illustrated content, the direction indicated by the x-axis is the first direction, and the direction indicated by the y-axis is the second direction. Each air guide portion 111 extending along the first direction is connected and communicates with an air guide portion 111 extending along the second direction. It will be appreciated that the multiple air guide portions 111 are arranged in regular rows and columns, which can make the distribution of the air guide portions 111 and the air holes 1101 more regular, helping to improve the uniformity of foaming.
[0040] It is understood that in this example, the first direction and the second direction may be perpendicular to each other. However, in other examples, the first direction and the second direction may also intersect at an angle.
[0041] Reference Figure 2As shown in some examples of this embodiment, each air guide portion 111 may be provided with a plurality of spaced pores 1101. Providing a plurality of spaced pores 1101 can improve the distribution density and uniformity of the pores 1101, thereby improving the foaming effect and uniformity of the rubber.
[0042] As some examples of this embodiment, both ends of the tubular air guide portion 111 may be closed, and the air holes 1101 are provided on the side walls of the air guide portion 111, so that the internal space of the air guide portion 111 is connected to the external space only through the air holes 1101 on the side walls, thereby preventing the rubber from penetrating into the air guide portion 111 from both ends and causing blockage.
[0043] It will be appreciated that in this embodiment, the blister element 110 extends entirely along a plane defined by two intersecting directions. However, in other embodiments, the blister element 110 may extend along three intersecting directions. The blister element 110 may have a regular or irregular shape, as long as it can guide the gas in the gas delivery tube 120 into the blister cavity 103.
[0044] Reference Figure 1 As shown in some examples of this embodiment, the rubber foaming device may include a plurality of foaming elements 110. The plurality of foaming elements 110 may be sequentially spaced apart in a direction from the rubber inlet 101 to the rubber outlet 102. Providing a plurality of foaming elements 110 allows more gas to penetrate into the rubber, thereby further improving the foaming effect of the rubber.
[0045] Combine Figure 1 and Figure 2 As shown in some examples of this embodiment, the direction from the glue inlet 101 to the glue outlet 102 is the third direction. The foaming member 110 includes a plurality of first air guides 111 extending along the first direction and a plurality of second air guides 112 extending along the second direction. The foaming member 110 as a whole can be planar and extend along a plane defined by the first and second directions. The third direction can intersect with both the first and second directions, which allows the flow direction of the rubber to intersect with the extension direction of the foaming member 110, thereby facilitating more complete contact between the rubber and the foaming member 110.
[0046] Furthermore, in this embodiment, the plurality of foaming elements 110 may be arranged in parallel along the direction from the glue inlet 101 to the glue outlet 102 .
[0047] Reference Figure 1As shown in some examples of this embodiment, the rubber foaming device may further include a one-way valve 130, disposed between the rubber inlet 101 and the foaming element 110. The one-way valve 130 is used to restrict the flow of the rubber from the rubber inlet 101 toward the rubber outlet 102. In actual use, the gas ejected from the air holes 1101 may cause some rubber to flow backward, affecting its quality. The further provision of the one-way valve 130 to restrict the flow of the rubber can prevent the problem of backflow and ensure that the rubber with the microbubble structure flows stably and unidirectionally within the foaming chamber 103.
[0048] Reference Figure 1 As shown in some examples of this embodiment, the diameter of the pores 1101 provided in the foaming element 110 is 0.1 mm to 7 mm. Setting the diameter of the pores 1101 between 0.1 mm and 7 mm helps ensure smooth gas discharge from the pores 1101 while preventing the rubber from seeping into the pores 1101 and causing blockage. In this example, the diameter of the pores 1101 can be 0.1 mm, 0.2 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, or 7 mm, or the diameter of the pores 1101 can be between any two of the above diameters.
[0049] It will be appreciated that, in this embodiment, the gas supply pipe 120 can be connected to a gas source to introduce gas into the foaming member 110. The gas in the gas source may include water vapor, which can promote the curing of the rubber. The water vapor in the microbubble structure has very good contact with the rubber, so the microbubble structure containing water vapor can significantly increase the curing rate of the rubber. Furthermore, the gas in the gas source may include, but is not limited to, one or more of air, nitrogen, and argon.
[0050] Furthermore, the present disclosure also provides a glue-spraying device, which includes an air intake device and a glue foaming device as described in any of the above embodiments. The air intake device is connected to the gas pipe 120 in the glue foaming device and is used to deliver gas to the gas pipe 120.
[0051] Figure 3 This is a structural diagram of a glue-spraying device. Figure 2 As shown in some examples of this embodiment, in this glue-spraying device, the air intake device may include a high-pressure air source (not shown), an air intake pipe 220, and a water storage container 210. One end of the air intake pipe 220 is connected to the high-pressure air source, and the other end of the air intake pipe 220 is disposed in the water storage container 210. The air delivery pipe 120 is connected to the water storage container 210.
[0052] In this embodiment, the high-pressure gas source contains gas at a pressure higher than atmospheric pressure. For example, the pressure of the gas in the high-pressure gas source can be 2 to 8 times atmospheric pressure. The rubber compound is generally viscous, and using a high-pressure gas source and delivering high-pressure gas helps the gas more fully penetrate the rubber compound.
[0053] In this embodiment, the water storage container 210 can store water and, when in use, is used to provide water vapor to the gas pipe 120. The water storage container 210 can be a sealed container. After entering the water storage container 210, the gas from the high-pressure gas source comes into contact with the water, carries water vapor, and is introduced into the gas pipe 120, thereby causing the gas delivered to the gas pipe 120 to contain water vapor.
[0054] As some examples of this embodiment, the glue application device may further include a heating component. The heating component is used to heat a medium, such as water, in the water storage container 210. The heating component can be located inside or outside the water storage container 210. The heating component can be mounted on the wall of the water storage container 210 or spaced apart from the water storage container 210, as long as it can heat the water in the water storage container 210. Using the heating component to heat the water in the water storage container 210 can promote the evaporation of water vapor, increase the water content of the gas in the gas pipeline 120, and further improve the curing rate of the glue during glue application.
[0055] As an example, the glue application device can be used as follows: glue is fed from the glue inlet 101 into the bubble chamber 103 of the glue container 100, gradually filling the bubble chamber 103. The heating component is activated to heat the water in the water storage container 210, maintaining the temperature between 20°C and 80°C. A high-pressure gas source is then activated to deliver high-pressure gas to the water storage container 210. The high-pressure gas then flows from the water storage container 210 into the gas pipe 120, into the bubble element 110, and ultimately out through the air holes 1101 into the glue, forming a microbubble structure within the glue. The glue with the microbubble structure then flows from the glue outlet 102 and is injected into the gap between the photovoltaic module frame and the laminate. The glue is then allowed to solidify. The curing of glues such as silicone glue requires a certain amount of water vapor, and the water vapor contained in the microbubble structure can directly accelerate the curing process from within the glue. Therefore, using the above glue application device for glue application can effectively increase the curing rate of the glue. Furthermore, the introduction of microbubbles into the rubber reduces its density, saving the actual amount of rubber used and, consequently, reducing the amount of silicone used. Furthermore, the microbubbles make the cured rubber fluffier and improve its elasticity, resulting in a better stress-buffering effect.
[0056] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.
[0057] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
