Description

Technical Field

[0001] The present invention relates to the field of LOGO display technology, and in particular to a three-dimensional luminous LOGO product and a manufacturing process thereof. Background Art

[0002] With the rapid development of the market economy, printing technology is constantly being updated with the progress of the times and the development of science and technology. In the overall value of products, printing and packaging account for an increasingly large proportion, and people's requirements for vision are getting higher and higher. More exquisite and eye-catching packaging will bring more added value to products.

[0003] The effects of ordinary flat LOGOs produced in the existing technology can no longer meet people's spiritual and aesthetic needs, while the three-dimensional, transparent, and luminous LOGOs that meet people's consumption needs are mainly produced through injection molding. The mold costs for early development and mass production are high, the production efficiency is slow, and there are also shortcomings such as poor shielding and no metallic texture.

[0004] Therefore, it is urgent to develop a three-dimensional LOGO product with simple production process, low production cost, good three-dimensional effect and luminous ability to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a three-dimensional luminous LOGO product and a production process thereof. By using the product and the production process, the production cost of the product can be reduced and the three-dimensional effect of the product can be improved.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a three-dimensional luminous LOGO product, which includes from top to bottom: a first transparent sheet layer, a first adhesive layer, a second transparent sheet layer, a second adhesive layer and a luminous component;

[0007] A first light shielding layer is disposed on the upper surface of the first transparent sheet layer, and an electroplating layer is disposed on the lower surface of the first transparent sheet layer;

[0008] The upper surface of the second transparent sheet layer is provided with a first color developing layer, the lower surface of the second transparent sheet layer is provided with a second color developing layer, the lower surface of the second color developing layer is provided with a second light shielding layer, and the second light shielding layer is provided with a hollow LOGO graphic;

[0012] In the above technical solution, a decoration layer is further provided on the upper surface of the first light-shielding layer, and the thickness of the decoration layer is 5-8 microns.

[0013] In the above technical solution, the thickness of the electroplating layer is 1 micron, the transmittance of the electroplating layer is 35%, and the material of the electroplating target material of the electroplating layer is one of chromium, aluminum, and nickel.

[0014] In the above technical solution, the material of the first transparent sheet layer and the second transparent sheet layer is one or a combination of any two of transparent PC, PMMA, and PET, and the thickness of the first transparent sheet layer and the second transparent sheet layer is 0.1 mm to 1.0 mm.

[0015] In the above technical solution, the first color-developing layer and the second color-developing layer are both UV transparent ink layers, the ink layer thickness is 1 micron to 3 microns, and the color of the ink layer is any one of the four colors of cyan, magenta, yellow, and black, as well as the special colors prepared by proportioning the four colors of cyan, magenta, yellow, and black.

[0016] In the above technical solution, the first light-shielding layer and the second light-shielding layer are both opaque black ink layers, and the thickness of the ink layer is 3 microns to 5 microns.

[0017] In the above technical solution, the first adhesive layer is OCA optical adhesive, and the second adhesive layer is transparent double-sided adhesive.

[0018] In the above technical solution, when the light-emitting component is not powered on, the color of the hollow LOGO image is determined by the colors of the first color rendering layer and the second color rendering layer. After the light-emitting component is powered on, the color of the hollow LOGO image is determined by the luminous color of the light-emitting component.

[0019] To achieve the above object, the present invention adopts a manufacturing process of a three-dimensional luminous LOGO product, which includes the following specific steps:

[0020] S 1. Material pretreatment: shrinking and double-sided hardening pretreatment of the materials of the first transparent sheet layer and the second transparent sheet layer at a temperature of 90° C. for 60 minutes;

[0021] S2. Electroplating: electroplating the lower surface of the first transparent sheet layer using an electroplating target, with a coating thickness of 1 micron and a transmittance of 35%;

[0022] S3. UV transfer: using a UV transfer process to transfer the first color developing layer and the second color developing layer to the upper surface and the lower surface of the second transparent sheet layer respectively, and curing by ultraviolet irradiation;

[0023] S4. Screen printing: Printing a first light-shielding layer on the upper surface of the first transparent sheet layer by screen printing, with a screen mesh of 300 meshes, a screen angle of 45 degrees, a drying temperature of 90°C, and a drying time of 60 minutes; and printing a second light-shielding layer on the lower surface of the second transparent sheet layer by screen printing, with a screen mesh of 300 meshes, a screen angle of 45 degrees, a drying temperature of 50°C, and a drying time of 30 minutes;

[0024] S5. Lamination: The first transparent sheet layer and the second transparent sheet layer are bonded together into a whole through a first adhesive layer;

[0025] S6. Composite protective film layer: composite a protective film layer on the upper surface of the first shading layer and the lower surface of the second shading layer;

[0026] S7. Punching and cutting: Punch holes at the four corners of the semi-finished product and cut and shape it according to the designed size and appearance;

[0027] S8. CNC engraving: CNC engraving equipment is used to perform three-dimensional shaping of the first shading layer of the semi-finished product;

[0028] S9. Composite light-emitting component: peel off the protective film layer on the lower surface of the second light-shielding layer, and use the second adhesive layer to bond the diffusion film layer of the light-emitting component and the second light-shielding layer together to form a final three-dimensional light-emitting LOGO product.

[0029] In the above technical solution, in step S4, the decorative layer can also be printed on the upper surface of the first light-shielding layer by screen printing, with a screen mesh of 420 meshes and a mesh angle of 45 degrees, and cured by ultraviolet irradiation.

[0030] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0031] 1. Molding process: The present invention prints the corresponding design pattern on the transparent sheet through UV transfer and silk screen printing process, and combines OCA optical glue and CNC numerical control precision carving molding process, and after composite molding with the light-emitting component, it becomes the three-dimensional luminous LOGO of the present invention. Compared with the injection molding process, the production process is simple, fast, and efficient, and is more suitable for large-scale industrial mass production;

[0032] 2. Molding cost: The present invention is formed by UV transfer, silk screen printing and CNC numerical control precision carving. The whole production process is flexible and controllable, and the design scheme can be modified quickly. Compared with the high cost of early development and mass production of molds in the injection molding process, the molding cost is greatly reduced. At the same time, if the injection molding process needs to present different colors, colorants need to be added to the injection masterbatch. The mixing time and cost of masterbatches of different colors are more expensive than printing and color matching. Therefore, the molding process of the present invention is more in line with the needs of industrial production;

[0033] 3. Product effect: The present invention uses an electroplating process to make the three-dimensional luminous logo have a strong metallic feel. At the same time, when the light is not on, the electroplated metal layer has a good shielding effect on the LED lamp, which will not affect the appearance of the three-dimensional luminous logo. Combined with the first color rendering layer and the second color rendering layer, the three-dimensional luminous logo can have richer colors and presentation effects. Compared with the injection molding process that requires the integration of different colors into the injection masterbatch and the limited color expression, the color printing process of the present invention makes color change faster and simpler, so that the three-dimensional luminous logo product of the present invention not only has flexible color change but also has a strong metallic texture.

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0040] Example 1: See Figure 1 , 2As shown, a three-dimensional luminous LOGO product includes, from top to bottom, a first transparent sheet layer 1, a first adhesive layer 2, a second transparent sheet layer 3, a second adhesive layer 4 and a luminous component 5;

[0041] The upper surface of the first transparent sheet layer 1 is provided with a first light shielding layer 11, and the lower surface of the first transparent sheet layer 1 is provided with an electroplating layer 12;

[0042] The upper surface of the second transparent sheet layer 3 is provided with a first color development layer 31, the lower surface of the second transparent sheet layer 3 is provided with a second color development layer 32, the lower surface of the second color development layer 32 is provided with a second light shielding layer 33, and the second light shielding layer 33 is provided with a hollow LOGO graphic 34;

[0043] The electroplating layer 12 on the lower surface of the first transparent sheet layer 1 and the first color development layer 31 on the upper surface of the second transparent sheet layer 3 are bonded together through the first bonding layer 2;

[0044] The light emitting assembly 5 comprises an LED array lamp layer 51, a diffusion film layer 52 arranged on the LED array lamp layer, and a power supply line group 53 connecting the LED array lamp layer;

[0045] The upper surface of the diffusion film layer 52 of the light emitting component 5 and the second light shielding layer 32 on the lower surface of the second transparent sheet layer 3 are bonded together by the second bonding layer 4 .

[0046] In this embodiment, the first transparent sheet layer 1 is selected from a pre-treated double-transparent PC material HC002 with double-sided hardening, with a thickness of 800 microns. Then, the first transparent sheet layer 1 is placed in an electroplating device, and the lower surface of the first transparent sheet layer is electroplated using a metal target material chromium to form an electroplated layer 12 with a thickness of 1 micron and a transmittance of 35%. Then, a screen printing process is used to print a first shading layer 11 on the upper surface of the first transparent sheet layer 1. The selected screen mesh number is 300 meshes, the mesh angle is 45 degrees, and the selected ink is opaque black ink. The ink layer thickness after screen printing is 3-5 microns, and then it is dried at a drying temperature of 90°C and a drying time of 60 minutes.

[0047] In this embodiment, the second transparent sheet layer 3 is made of pre-treated double-transparent PC material HC002 with double-sided hardening, with a thickness of 100 microns. Then, the first color-developing layer 31 and the second color-developing layer 32 are transferred on the upper surface and the lower surface of the second transparent sheet layer 3 respectively by UV transfer process, and cured by ultraviolet irradiation. The selected ink is a UV transparent black ink layer, and the thickness of the transferred ink layer is 1-2 microns. Then, the second shading layer 33 is printed on the lower surface of the second transparent sheet layer 3 by screen printing process. The mesh number of the screen is 300 meshes, the mesh angle is 45 degrees, the selected ink is an opaque black ink, the thickness of the ink layer after screen printing is 3-5 microns, and it is dried at a drying temperature of 50°C and a drying time of 30 minutes.

[0048] The OCA optical glue selected in this embodiment is used as the first adhesive layer 2 to bond the first transparent sheet layer 1 and the second transparent sheet layer 3. After the bonding is completed, a protective film layer 6 is compounded on the upper surface of the first shading layer 11 and the lower surface of the second shading layer 33 to protect the surface of the semi-finished product. Then, it is cut according to the designed size, and through holes 35 are punched in the four corners. Finally, CNC numerical control precision engraving equipment is used to perform three-dimensional stereo molding on one side of the first shading layer 11 of the semi-finished product to obtain a semi-finished product.

[0049] In this embodiment, a transparent double-sided tape is used as the second adhesive layer 4 to bond one side of the diffusion film layer 52 of the light-emitting component 5 to one side of the second shading layer 32. The diffusion film layer 52 makes the light-emitting effect of the LED array lamp layer more uniform, so that the appearance of the light-emitting logo is better. Before bonding, it is necessary to peel off the protective film layer 6 on the lower surface of the second shading layer 33 to complete the production of the final product. When in use, the power supply line group 53 of the light-emitting component 5 is connected to electricity to achieve light emission.

[0050] When the light-emitting component 5 is not powered on, the first color layer 31 and the second color layer 32 appear black under natural light. After the light-emitting component 5 is powered on and emits light, the first color layer 31 and the second color layer 32 appear as the luminous color of the LED array lamp layer 51 under natural light under the action of the LED array lamp layer 51 of the light-emitting component 5. This is because the UV transparent black ink layer used in the first color layer 31 and the second color layer 32 has good light transmittance.

[0051] To achieve the above object, the present invention adopts a three-dimensional luminous LOGO production process, which includes the following specific steps:

[0052] S 1. Material pretreatment: shrinking and double-sided hardening pretreatment of the materials of the first transparent sheet layer 1 and the second transparent sheet layer 3 at a temperature of 90° C. for 60 minutes;

[0053] S2. Electroplating: Electroplating the lower surface of the first transparent sheet layer 1 using an electroplating target to form an electroplating layer 12, the coating thickness is 1 micron, the transmittance is 35%, and the electroplating target selected in this embodiment is chromium;

[0054] S3. UV transfer: using a UV transfer process to transfer the first color developing layer 31 and the second color developing layer 32 to the upper surface and the lower surface of the second transparent sheet layer 3, respectively, and curing by ultraviolet irradiation;

[0055] S4. Screen printing: The first light shielding layer 11 is printed on the upper surface of the first transparent sheet layer 1 by screen printing, the mesh number of the screen is 300 meshes, the mesh angle is 45 degrees, the drying temperature is 90°C, and the drying time is 60 minutes. The second light shielding layer 33 is printed on the lower surface of the second transparent sheet layer 3 by screen printing, the mesh number of the screen is 300 meshes, the mesh angle is 45 degrees, the drying temperature is 50°C, and the drying time is 30 minutes.

[0056] S5. Lamination: The first transparent sheet layer 1 and the second transparent sheet layer 3 are bonded together into a whole through the first adhesive layer 2;

[0057] S6. Composite protective film layer: a composite protective film layer 6 is formed on the upper surface of the first shading layer 11 and the lower surface of the second shading layer 33;

[0058] S7. Punching and cutting: Punch holes at the four corners of the semi-finished product and cut and shape it according to the designed size and appearance;

[0059] S8. CNC carving: CNC carving equipment is used to perform three-dimensional molding of a three-dimensional appearance on one side of the first shading layer 11 of the semi-finished product;

[0060] S9. Composite light-emitting component: remove the protective film layer 6 on the lower surface of the second light-shielding layer 33, and use the second adhesive layer 4 to bond the diffusion film layer 52 of the light-emitting component 5 and the second light-shielding layer 33 together to form a final three-dimensional light-emitting LOGO product.

[0061] Example 2: See Figure 3 , 4As shown, a three-dimensional luminous LOGO product, in this embodiment, its structure is basically similar to that of the first embodiment, except that: the first transparent sheet layer 1 of this embodiment selects a double-transparent PC material HC002 that is hardened on both sides with a thickness of 600 microns, the second transparent sheet layer 3 selects a double-transparent PET material that is hardened on both sides with a thickness of 200 microns, and a decorative layer 13 is added on the upper surface of the first shading layer 11. The decorative layer 13 is printed using a screen printing process, the selected screen mesh number is 420 mesh, the mesh angle is 45 degrees, the selected ink is UV matte oil, the thickness of the ink layer completed by screen printing is 5-8 microns, and it is cured by ultraviolet irradiation. The remaining structure is consistent with the first embodiment, and the decorative layer 13 is added to make it closer to the texture of the shell of the electronic device used.

[0062] Since a decorative layer 13 is added in this embodiment, the production steps are changed compared with the production steps in Example 1. The main difference between the production steps in Example 1 and that in the production process of this embodiment, in the S4 step, it is necessary to use a screen printing process to print the decorative layer 13 on the upper surface of the first shading layer 11. The mesh number of the screen is 420, the mesh angle is 45 degrees, and it is cured by ultraviolet irradiation. The remaining production process steps are consistent with those in Example 1.
