Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a manufacturing process and packaging method of a color photovoltaic module with naked-eye 3D effect. Background Art

[0002] As the global climate gradually warms, the greenhouse effect continues to accumulate, and non-renewable energy is gradually consumed, solar energy, as a clean and renewable energy, has become more and more widely used. It is involved in many fields such as photovoltaic building materials, solar cars, solar luggage and solar pavement. As the price of raw materials for solar cells continues to decline and solar power generation technology gradually matures, solar power generation will usher in a broader space for development.

[0003] Since traditional solar cells are relatively single in color, generally black, green or blue, they cannot meet aesthetic requirements in many application scenarios. They appear abrupt after application and cannot match the application scenarios, which greatly limits the scope of use and affects the user's visual experience. Therefore, it is particularly important to change the color of traditional photovoltaic modules. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a manufacturing process and packaging method for a color photovoltaic component with a naked-eye 3D effect, which solves the problem that the existing color photovoltaics have low viewing quality due to single color and lack of three-dimensionality.

[0006] (II) Technical solution

[0007] The purpose of the present invention is to provide a naked-eye 3D production process based on color photovoltaic technology. This process produces color patterns on photovoltaic panels made of transparent materials and combines them with naked-eye 3D technology to enable the photovoltaic panels to have both high photovoltaic power generation efficiency and three-dimensional color images, thereby improving the ornamental and artistic qualities of the photovoltaic panels.

[0008] The present invention is implemented by the following technical scheme: a process for manufacturing a color photovoltaic module with naked eye 3D effect, comprising the following steps: step 1, selecting a transparent material with high light transmittance as a substrate of a photovoltaic panel, using KEA software to generate a color pattern of a 3D background through a logo graphic in a hexagonal arrangement, using this pattern as the first layer spraying file, using full-color micro-layer technology to spray the color layer, and using mirroring operation;

[0009] Step 2: Spray the second layer with white. Spray the length and width of white according to the length and width of the color. Keep the spraying range consistent and use the gradient function.

[0010] Step 3: Flip the material left to right and spray the transparent varnish surface. Spray the varnish into a dot grating pattern corresponding to the base color image, and form a naked-eye 3D effect through thickness difference. Through multiple printing, the varnish is stacked into dots in sequence, and the varnish is subjected to delayed curing treatment.

[0011] Preferably, the thickness of the photovoltaic panel substrate in step one is set to 2 to 3 mm.

[0012] Preferably, the color pattern is printed using a 3p l print head, and the white pattern is printed using a 30p l print head.

[0013] Preferably, in step 1, the overall image of the color layer is 3 to 5 mm smaller than the material.

[0014] Preferably, the printing dpi of the varnish in step three is consistent.

[0016] S1. Spray a layer of adhesive on the surface of the photovoltaic module to bond the 3D material colored white layer to the photovoltaic panel;

[0017] S2. The material is transferred into a curing machine at a curing speed of 1 m / s and cured using an ultraviolet lamp with a wavelength of 360 nm to 395 nm to complete the encapsulation of the photovoltaic module.

[0022] 1. The photovoltaic module manufacturing process uses transparent materials with high light transmittance as the base of the photovoltaic panel. Combined with the high light transmittance characteristics, this choice not only ensures the high efficiency of photovoltaic power generation of photovoltaic modules, but also provides a basis for the subsequent naked-eye 3D effect.

[0026] Figure 2 It is a schematic diagram of logo in the present invention. DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] like Figure 1-2 As shown, an embodiment of the present invention provides a process for manufacturing a color photovoltaic module with a naked-eye 3D effect, comprising the following steps:

[0030] First of all, the material for this process needs to be transparent. In addition, considering the need for good photovoltaic power generation efficiency, the transparent material has high light transmittance. Use KEA software to generate a 3D background color pattern through this logo graphic and select a hexagonal arrangement. This arrangement is more three-dimensional. Please refer to the arrangement method. Figure 1 As shown, logo reference Figure 2 This pattern is the first layer of spraying file. The color layer is sprayed using full-color micro-layer technology, mirroring, and using the gradient function to prevent hot spots on photovoltaic modules. The overall picture is 3 to 5 mm smaller than the material. Because the points that generate the 3D effect are very small and densely arranged, the software that generates the 3D color map is KEA. Therefore, in order to make the imaging effect better and more three-dimensional, the color part is printed using a 3p l print head, and the printing effect is more precise;

[0031] The second layer is sprayed with white. The length and width of white are sprayed according to the length and width of color. The spraying range is consistent. The gradient function is used to prevent hot spots from occurring in photovoltaic modules. The overall picture is 3 to 5mm smaller than the material and consistent with the color. In order to transmit light, the white layer uses a 30pl printing head with a larger spacing between ink dots, which can allow more light to enter. White reflects all light, so a larger pl print head is used. The spacing between ink dots is larger, which can allow more light to enter.

[0032] After the above two steps are completed, turn the material over from left to right. This side is sprayed with transparent varnish. The varnish is sprayed into a dot raster pattern corresponding to the base color image, and the naked eye 3D effect is formed through the thickness difference. Through multiple printing methods, the varnish is stacked into dots in sequence, and the varnish is delayed by curing to make the effect more three-dimensional. The printing dpi of the varnish should be consistent, for example, 720dpix720dpi. For high-definition color images, a 3pl (picoliter) print head is used, and for light-transmitting white, a 30pl print head is used. White reflects all light, so a larger pl print head is used, and the spacing between ink dots is larger.

[0033] A packaging method for a colored photovoltaic module with a naked-eye 3D effect is a room-temperature packaging method. A layer of adhesive is sprayed on the surface of the photovoltaic module to bond the colored white layer of the 3D material to the photovoltaic panel to ensure uniform spraying of the adhesive. After confirmation, the material is conveyed to a curing machine at a curing speed of 1 m / s. The material is cured using an ultraviolet lamp with a wavelength of 360 nm to 395 nm. After the curing is completed, check whether the bonding is firm and confirm whether there is any glue overflow.

[0034] The frame height of the photovoltaic module is 2mm to 3mm, and the material selected is 2mm to 3mm transparent material. This frame can achieve a naked-eye 3D effect, which can not only generate electricity, but also be beautiful, newer and unique, and increase selling points, such as acrylic, glass, transparent stickers and other high-light-transmittance materials.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
