Description

Technical Field

[0001] The present invention belongs to the field of photovoltaic technology, and in particular relates to a laminating device suitable for a BIPV production line. Background Art

[0002] The so-called BIPV photovoltaic building integration is a building-integrated photovoltaic power station system that integrates solar panels into the facade, roof and other parts of the building.

[0003] As people's reliance on renewable energy increases and their awareness of environmental protection improves, more and more buildings will adopt BIPV technology. Compared with traditional BAPV, BIPV has certain advantages in safety, ornamental, convenience and subsequent maintenance. Since each building design style, function and building application scenario are different, the appearance (flat or curved), size and thickness requirements of BIPV products are also different. The same lamination equipment cannot be used for packaging during the lamination process. Summary of the invention

[0004] The purpose of the present invention is to provide a laminating device suitable for a BIPV production line, so as to solve the technical problem that the BIPV products have different requirements on appearance (flat or curved), size and thickness, and the products cannot be packaged using the same laminating equipment during the lamination process, so as to achieve the purpose of laminating applications corresponding to different types of components, including different sizes, thicknesses and shapes.

[0005] In order to solve the above technical problems, the present invention provides a laminating device suitable for a BIPV production line, comprising:

[0006] Laminator body and laminating tooling;

[0007] The laminator body comprises a laminating lower chamber, a laminating upper chamber, a lifting system, a vacuum system and a sealing mechanism, wherein the laminating lower chamber is located below the laminating upper chamber and forms a chamber, the lifting system controls the rise and fall of the laminating upper chamber, and the vacuum system vacuums the chamber formed between the laminating lower chamber and the laminating upper chamber;

[0008] The laminating tool is detachably arranged above the laminating upper chamber, and the BIPV product is laminated by the laminating tool;

[0009] The lamination upper chamber is provided with a lamination skin at a position opposite to the lamination lower chamber, and the lamination lower chamber and the lamination upper chamber are provided with vacuum valves to produce a vacuum system;

[0010] The laminate is pressed subcutaneously and flexibly fitted with the BIPV product, and the packaging of the BIPV product is completed by vacuuming and pressurizing.

[0011] Furthermore, a heating plate and a high temperature resistant cloth are arranged above the lamination lower chamber, the heating plate is laid flat above the lamination lower chamber, and the high temperature resistant cloth is laid flat on the heating plate.

[0012] Furthermore, the height of the laminating upper chamber is greater than the superimposed thickness of the laminating tooling and the BIPV product.

[0013] Furthermore, the lamination tooling is placed with at least one BIPV product.

[0014] Furthermore, the lamination tooling is a lamination pad for use in flat BIPV products.

[0015] Furthermore, a single lamination tool is used to place at least one BIPV product.

[0016] Furthermore, the height of the lamination upper chamber is greater than the height of the lamination tooling and the BIPV product.

[0017] Furthermore, the laminated spacer includes at least one U-shaped frame to place the BIPV product.

[0018] Furthermore, the U-shaped frame is a mesh structure.

[0019] Furthermore, the laminated skin is made of flexible high temperature resistant material, and is selected from one or more of silicone skin, rubber skin or silicone rubber skin.

[0020] The beneficial effects of the present invention are:

[0021] 1. Through the laminating machine body and laminating tooling, the thickness range of the BIPV product cavity is expanded, which can not only meet the requirements of flat components of various thickness types, but also is suitable for the lamination process of various anisotropic and curved components.

[0022] 2. Different component types can be realized by simply replacing different lamination tools, with simple editing and fast switching.

[0023] 3. Lamination pads are set on the lamination tooling to ensure that after the laminated skin is pressed subcutaneously, the components are evenly stressed on the four sides and four corners during the lamination process, and there is no delamination, bubbles or other defects on the edges.

[0024] 4. While improving the yield of components, the service life of the laminated skin is improved through the soft contact between the laminated pad and the laminated skin, solving the problem of laminated skin loss caused by direct hard contact between the component and the laminated skin.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0039] Embodiment:

[0040] As Figures 1 to 3 shown, a lamination device applicable to a BIPV production line includes: a laminator main body 1 and a lamination tooling 2.

[0041] Among them, the laminating machine body 1 includes a laminating lower chamber 11, a laminating upper chamber 12, a lifting system 13, a vacuum system 14 and a sealing mechanism 15. The laminating lower chamber 11 is located below the laminating upper chamber 12 and forms a chamber. The lifting system 13 controls the rise and fall of the laminating upper chamber 12. The vacuum system 14 forms a chamber between the laminating lower chamber 11 and the laminating upper chamber 12 with vacuum.

[0042] like Figures 1 to 3 As shown, the laminating tool 2 is detachably arranged above the laminating upper chamber 12, and the BIPV product is laminated by the laminating tool 2; the laminating upper chamber 12 is provided with a laminating skin 3 at the position of the laminating lower chamber 11, and the laminating lower chamber 11 and the laminating upper chamber 12 are provided with a vacuum valve 4 to generate a vacuum system 14; the laminating skin 3 is pressed down to flexibly fit the BIPV product, and the packaging of the BIPV product is completed by vacuuming and pressurizing, so that the BIPV product component materials can be tightly combined. In this embodiment, the laminating skin 3 is made of flexible high temperature resistant material, and one or more of silicone skin, rubber skin or silicone rubber skin is selected.

[0043] The height of the laminating upper chamber 12 is greater than the thickness of the laminating tooling 2 and the BIPV product stacked together, so that the laminating tooling 2 and the BIPV product can be placed in the laminating upper chamber 12 .

[0044] In this embodiment, at least one BIPV product is placed in the laminating tool 2. The laminating tool 2 can be placed with a single BIPV product or multiple BIPV products.

[0045] like Figures 1 to 3 As shown, a heating plate 5 and a high temperature resistant cloth 6 are arranged above the laminating chamber 11. The heating plate 5 is laid flat above the laminating chamber 11, and the high temperature resistant cloth 6 is laid flat on the heating plate 5. Heating can improve the plasticity of the material, making it easier for different materials to fuse at high temperatures, thereby forming an integrated product. The high temperature resistant cloth 6 prevents the adhesive film from sticking after the components are laminated, making it easier to clean and remove the components.

[0046] like Figures 1 to 3 As shown, the laminating tool 2 is a laminating pad 7 for a flat BIPV product. When the BIPV product component is a curved anisotropic component, the laminating tool 2 is a heating plate 5 and a laminating pad 7. The shape of the upper surface of the heating plate 5 is consistent with the shape of the component, and the lower surface is flat and is directly placed on the high temperature cloth of the laminating lower chamber 11. The laminating pad 7 can be made of high temperature resistant materials such as rubber and polyurethane.

[0047] The height of the lamination upper chamber 12 is greater than the height of the lamination tooling 2 and the BIPV product.

[0048] like Figures 1 to 3As shown, the laminated spacer 7 includes at least one U-shaped frame 71 to place the BIPV product. The U-shaped frame 71 is a mesh structure. The laminated spacer 7 can be arranged in a single or multiple configurations.

[0049] The BIPV product component is placed in the center of the hollow position corresponding to the laminating pad 7. The length and width of the hollow are 1-3mm larger than the BIPV product component. The height of the laminating pad 7 is 0.2-1.2mm higher than the BIPV product component, so as to reduce the pressure around the BIPV product component during lamination and improve abnormalities such as delamination and bubbles at the edge of the component.

[0050] The laminating tool 2 is provided with a laminating pad 7 to ensure that after the laminating skin 3 is pressed down, the BIPV product module is evenly stressed on the four sides and four corners during the laminating process, and there is no delamination, bubbles, etc. on the edges. While improving the module yield, the laminating pad 7 and the laminating skin 3 are in soft contact, which also increases the service life of the laminating skin 3 and solves the problem of loss of the laminating skin 3 caused by direct hard contact between the module and the laminating skin 3.

[0051] In summary: Through the laminating machine body 1 and the laminating tool 2, the thickness range of the BIPV product cavity is expanded, which can not only meet the requirements of flat components of various thickness types, but also is suitable for the lamination process of various anisotropic and curved components. Different component types can be realized by simply replacing different laminating tools 2. The operation is simple to edit and the switching speed is fast. A laminating pad 7 is set on the laminating tool 2 to ensure that after the laminate skin 3 is pressed down, the four sides and four corners of the component are evenly stressed during the lamination process, and there is no delamination, bubbles and other defects on the edges. While improving the yield of the component, the soft contact between the laminating pad 7 and the laminate skin 3 also increases the service life of the laminate skin 3, solving the problem of laminate skin 3 loss caused by direct hard contact between the component and the laminate skin 3.

[0052] The various devices selected in this application are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
