[0020] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model. The present utility model will be described in detail below with reference to the drawings.

[0021] As Figure 1 shown, an electronic device accessory with 3D glass fiber spraying and embossing provided by the present utility model includes a glass fiber layer 1. A paint layer 2 is provided on the glass fiber layer 1. An inner texture layer 3 is provided at one end of the paint layer 2 away from the glass fiber layer 1. An electroplated layer 4 is plated at one end of the inner texture layer 3 away from the paint layer 2. A protective layer 5 is provided at one end of the electroplated layer 4 away from the inner texture layer 3. A LOGO layer 6 is transfer-printed at one end of the protective layer 5 away from the protective layer 5;

[0022] The glass fiber layer 1 is prepared by hot pressing glass fiber material and then cooling and curing it. Specifically: First, cut a glass fiber layer 1 with a suitable specification from prepreg glass fiber or thermoplastic glass fiber. Then, heat the glass fiber layer 1 to make it melt. Next, hot press the melted glass fiber layer 1 into the required shape. Finally, cool and cure the glass fiber layer 1. Then, successively arrange a paint layer 2, an inner texture layer 3, a plating layer 4, a protective layer 5, and a LOGO layer 6. Since the glass fiber layer 1 used in the present utility model has undergone a cooling and curing forming process once when it is used as a raw material before cutting, and it also needs to undergo a hot pressing and then cooling and curing forming process when forming the glass fiber layer 1 of the present utility model, that is, the glass fiber layer 1 that has undergone two cooling and curing treatments has higher strength compared to the glass fiber layer 1 that has undergone one cooling and curing treatment. Therefore, under the premise of a smaller thickness of the glass fiber layer 1, the required strength requirements can still be achieved, reducing the overall thickness of the present utility model, which is beneficial for cooperating with other electronic accessories and making room.

[0023] In this embodiment, an outer texture layer 7 is embossed at one end of the LOGO layer 6 away from the protective layer 5. The outer texture layer 7 is made by a customer-selected texture and then formed by a specific silicone texture mold. Then, the formed outer texture layer 7 is set on the LOGO layer 6 by embossing and then cured. Among them, for the forming and transfer printing of the outer texture layer 7, the irradiation and curing of an LED lamp and a mercury lamp are required successively. The energy of the LED lamp is 400 - 1000 mj, and the energy of the mercury lamp is 600 - 1500 mj.

[0024] In this embodiment, the thickness of the outer texture layer 7 is 6 - 12 μm. Besides having obvious texture, it will not cause the overall size of the present utility model to be too large due to excessive thickness.

[0025] In this embodiment, a micro-structure layer 8 is provided at one end of the LOGO layer 6 connected to the outer texture layer 7. The micro-structure layer 8 is used to enhance the embossing effect of the outer texture layer 7. That is, the micro-structure includes a plurality of protrusions, and the protrusions are used to increase the contact area with the outer texture layer 7. Thus, during embossing, the outer texture layer 7 can be more stably attached to the LOGO layer 6.

[0026] In this embodiment, both the paint layer 2 and the protective layer 5 are formed by an atomization process, and the thicknesses of the paint layer 2 and the protective layer 5 are both 9 - 25 μm.

[0027] That is, the materials used for the color paint layer 2 and the protective layer 5 are both paints. The main difference lies in the types of paints used. During processing, the corresponding paint is atomized onto the glass fiber layer 1 / electroplated layer 4 by means of a mechanical spray gun, so that the paint is evenly distributed. The thickness of the color paint layer 2 and the protective layer 5 being 9 - 25 μm also ensures that the required color effect can be accurately presented. Then, the color paint layer 2 / protective layer 5 is baked under the condition of a temperature of 50 - 65 °C to ensure the adhesion effect of the color paint layer 2 / protective layer 5.

[0028] Specifically, the number of the color paint layers 2 is at least one layer, and it can also be two layers or more. Only the state of one layer is shown in this embodiment. The number of the color paint layers 2 of the chicken leg is mainly determined by the requirements of the desired color and the surface effect of the glass fiber layer 1, which will not be elaborated here. And the above 9 - 25 μm is the thickness of one layer of the color paint layer 2.

[0029] In this embodiment, the electroplated layer 4 is disposed on the inner texture layer 3 by an optical electroplating or magnetron sputtering process, and the thickness of the electroplated layer 4 is 30 - 300 nm.

[0030] In this embodiment, the inner texture layer 3 is disposed on the color paint layer 2 by a transfer printing process, and the thickness of the inner texture layer 3 is 6 - 12 μm. The inner texture layer 3 is formed by a customer - selected texture and then a specific silicone texture mold. Then, the formed inner texture layer 3 is disposed on the color paint layer 2 by rubbing, and then cured. Among them, for the forming and transfer printing of the inner texture layer 3, the irradiation and curing of an LED lamp and a mercury lamp are used successively. The energy of the LED lamp is 400 - 1000 mj, and the energy of the mercury lamp is 600 - 1500 mj.

[0031] The structure of the inner texture layer 3 and the outer texture layer 7 is basically the same at the upper level, but the inner texture layer 3 needs to adopt a transfer printing process, while the outer texture layer 7 needs to adopt a rubbing process to meet the required requirements.

[0032] In this embodiment, the thickness of the LOGO layer 6 is 3 - 7 μm. Specifically, the LOGO layer 6 is printed onto the protective layer 5 by means of steel plate printing, and then baked for 30 - 60 min under the condition of 60 - 90 °C to form. The main material of the LOGO layer 6 is also ink. In order to avoid generating a step structure, it is preferably that the image position of the LOGO layer 6 uses corresponding color / multiple - color inks, and the non - image position uses transparent ink / colloid for filling.

[0033] In this embodiment, the surface of the glass fiber layer 1 has an adhesion layer 9, and the adhesion layer 9 is connected to the inner texture layer 3. The effect of the adhesion layer 9 is basically the same as that of the micro - structure layer 8, and their structures can be the same or have obvious differences, which will not be elaborated here.

[0034] As described above, it is only a preferred embodiment of the present utility model, and there is no restriction on the present utility model in any form. Although the present utility model is disclosed above in a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, when making some changes or modifications using the above-disclosed technical content to equivalent embodiments of equivalent changes, but as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical solution of the present utility model shall fall within the scope of the technical solution of the present utility model.
