Description

Technical Field

[0001] This invention relates to a naked-eye 3D primitive technology, and particularly to a method for printing suspended naked-eye 3D primitives and its integrated production equipment. Background Technology

[0002] With the development of technology and the progress of the times, naked-eye 3D printing is becoming increasingly prominent in terms of market demand and importance. Various industries are demanding more and more naked-eye 3D printing, and the technical requirements are also getting higher and higher.

[0003] Traditional naked-eye 3D printing generally refers to lenticular 3D printing, which is a three-dimensional effect presented by combining planar printed graphics with lenticular grating film. Its drawbacks are that the 3D layers are not rich, and the diversity and large-format production are limited by the lenticular grating film material. The maximum size can only be within 200*200mm, and the thickness of the transparent body is only between 12-20um, which cannot meet the needs of large-format and multi-layer floating primitive effects.

[0004] With the development of computer software technology, photolithography technology, and printing technology, computer-aided photolithography design software is used to design and edit multi-layered suspended primitives. Then, a photolithography machine is used to photolithographically etch the primitives designed and edited by the computer software into a master plate, followed by development, and then electroforming a nickel roller to generate a nickel roller template with micro-nano primitive structures. Finally, the micro-nano structure primitives on the nickel roller template are transferred to paper using PET transfer technology. However, due to the involvement of many high-end technologies, the technology is complex and difficult, especially the current photolithography software programs, which are complex and inconvenient for designing and editing primitives, particularly lacking preview functionality, i.e., the preview of the already designed primitives is limited. The designed and edited naked-eye 3D primitives cannot be directly inspected and corrected. The effect can only be seen after photolithography and development. If there is any error or inaccuracy, the photolithography design software must be used to modify the effect based on the developed image. The photolithography and development process must be repeated before the effect can be inspected and corrected. For suspended stereoscopic effects, errors can only be detected after the transfer is successful. This leads to design and editing difficulties, long working hours, low production efficiency, and increased unnecessary sample costs, which increases the overall production cost and makes it difficult to popularize and mass-produce applications.

[0005] Furthermore, when printing photolithographic primitives in batches, they need to go through an independent coating process, and then the coated semi-finished products are transported to the aluminum plating workshop for aluminum plating production; then they are transported to the paper coating production line to finally produce naked-eye 3D primitive finished products. Such multiple discrete processes result in the inconvenience of transporting semi-finished products, low production efficiency, and high production costs.

[0006] To address the aforementioned pressing challenges, we actively organized our technical team, summarized years of production experience and practical lessons learned, and combined them with relevant technical theories to conduct in-depth exploration and research. We carried out a great deal of creative work, including design, experimentation, trial use, optimization, and improvement, on the photolithography technology and printing system for naked-eye 3D primitives. Summary of the Invention

[0007] To address the technical problems mentioned in the background section, this invention provides a method for printing levitation naked-eye 3D primitives and its integrated production equipment. This method allows for previewing and editing 3D primitive effects within photolithography software, and integrates coating, aluminizing, and paper-coating processes on a single production line. The resulting naked-eye 3D primitives exhibit high transparency, a clear 3D levitation effect, and are free from yellowing or whitening defects, achieving high-speed, high-efficiency, and high-quality production in a single process.

[0008] The technical solution of this invention to solve its technical problem is:

[0009] 1. Computer-aided design (CAD) software is used to design images, and then photolithography design software is used to design and edit multi-layered suspended 3D primitives. A 3D primitive preview program and menu are added to the photolithography design software. Furthermore, a lighting effect setting program is included to improve the preview effect, making it more realistic. 2. To solve the problems of inconvenient handling of semi-finished products, low production efficiency, and high costs caused by the separation of multiple processes in the mass printing of photolithographic primitives in existing technologies, the production equipment for photocoating, metallization, and paper coating processes is combined in one workshop. The PET base film and PET coated semi-finished product from the end of the coating process equipment are led to the metallization equipment for direct metallization. Then, the PET base film, PET coating, and metallized layer semi-finished product from the end of the metallization equipment are led to the paper coating production line for paper coating, drying, and winding to produce naked-eye 3D primitive products. However, this process faces the problem that due to the short distance between coating and metallization, cooling is time-consuming and slow. The short forming time can cause the transparent material to appear slightly yellow, have low transparency, and appear slightly whitish. To address this issue, temperature control devices are installed in the upper and lower sections before and after molding in the coating process, and heat dissipation devices are installed in the lower and lower sections before and after rolling in the coating process. A cold roller conveyor is also installed between coating and aluminizing to further cool and stabilize the micro-nano structure of the PET coated material after molding. Furthermore, temperature control devices are installed in the upper rear section of the paper-coating roll and cooling devices are installed in the lower rear section of the paper-coating roll to ensure buffering when the transparent material exchanges with the ambient temperature, thus ensuring the stability of the transparent material and the 3D micro-nano structure.

[0010] A method for printing suspended naked-eye 3D graphics using the above-mentioned technical solution and its integrated production equipment include planar image design, suspended graphics photolithography design, photolithography, development, electroforming nickel roller and nickel roller graphics molding; it also includes PET base film, PET coating, temperature control equipment A, heat dissipation device A, graphics molding, rotating heat sink, temperature control equipment B, heat dissipation device B, roller cold conveying, aluminizing, adhesive coating, paper covering, temperature control equipment C, heat dissipation device C, naked-eye 3D graphics product, and finished product winding; characterized in that the suspended graphics photolithography design, temperature control equipment A, heat dissipation device A, temperature control equipment B, heat dissipation device B, rotating heat sink, roller cold conveying, temperature control equipment C, and heat dissipation device C;

[0011] The graphic element molding process involves synchronous rolling and pressing of a nickel roller graphic element mold and a rotating heat sink.

[0012] The nickel roller graphic element mold is manufactured as follows: planar image design—suspended graphic element photolithography design—photolithography by a photolithography machine—development by a developing equipment—and electroforming nickel roller process; the maximum size of the nickel roller graphic element mold can be 600*600mm, and the maximum depth of the graphic element and the thickness of the transparent body can be 120-240um; the nickel roller graphic element mold is used to install in the printing system.

[0013] The planar image design uses two-dimensional primitive design software to design two-dimensional images;

[0014] The aforementioned levitation design software includes gradient dynamic mode, image mode, relief mode, and matte mode. Its key feature is that it also includes a 3D levitation floating mode, a microarray structure mode, and a preview effect mode. The software operates on a Windows 10 / 11 64-bit operating system environment. It features menus for "Hologram," "Layer," "Options," "Add Image," "Glasses-Free 3D," "Power," and "Help," as well as menus for "Show Ruler," "Show Outline," "Single Layer Movement," "Entire Layer Movement," "Crop Selection," "Object," "Auto Snap," and "Reference Lines," making the design and editing of levitation 3D primitives convenient and quick. The preview mode allows users to preview the levitation 3D primitive effect before the pattern is exposed on the printing plate.

[0015] The design and editing method of the photolithography design software is as follows: Open the software, click the "Add Image" window in the menu, import it into the "Load" frame, click the "Naked-eye 3D" effect mode, and you can see the mode parameters for adjustment at the bottom of the table. Set the "Depth" value. This "Depth" setting can achieve a multi-layered, flowing effect. It has positive and negative values, with a maximum range of "+20~-20". The "Depth" value is adjusted in units of "2". The larger the value, the more layers there are, and the smaller the value, the fewer the layers. When the "Depth" is set to 10, the pattern has better and clearer layers.

[0016] Below "Depth" is a "Measured Depth" setting. The larger this value is, the better the depth of the body space; the smaller the value is, the worse the depth of the body space. You can set it arbitrarily within the range of "0~10". The "Measured Depth" value is adjusted in units of "1". When the value is set to "10", the depth effect is better.

[0017] To achieve a visually flowing image effect, the "Distant View" value below the "Measured Depth" value needs to be set. The value of this function can be set between 0 and 5, with each "0.5" increment as the adjustment unit. When the setting is "2", the visually flowing image effect of the pattern will be better.

[0018] Further, the lithography engraving effect is set up. This effect is a wide-view engraving effect, usually without color, presenting a single bright metallic luster. The engraved surface is calculated using the lithography software in the project manager, and then the surface is cut into micro-nano-level equal-height layers. Each surface segment is then moved to a single layer, creating a raised metallic luster, visible only with a magnifying glass of at least 50x. After importing the designed engraving pattern into the lithography software in the project manager, clicking the "Engraving" mode effect will display the mode effect parameter settings below "Add Image." The "Power" value determines the number of outlines in the engraved image, ranging from 1 to 20. Larger engraved patterns require higher "Power" values ​​(maximum 20), while smaller patterns require lower values ​​(minimum 1). Setting the "Power" value to the maximum of 20 results in a better engraving effect and a more prominent metallic texture. At higher magnification, a larger outline area produces the best effect.

[0019] Temperature control devices A, B, and C are described above. Temperature control device A is located between the PET coating equipment and the graphic molding equipment, and mainly controls and stabilizes the temperature of the PET after coating. Temperature control device B is located at the end of the graphic molding process and mainly controls the temperature of the PET after molding. Temperature control device C is located at the end of the paper-coating roller pressing equipment and mainly controls the temperature of the naked-eye 3D graphic after paper coating.

[0020] The heat dissipation devices A, B, and C are described above. Heat dissipation device A is paired with temperature control device A and is installed under the conveyor rollers of temperature control device A to cool the conveyor rollers and the PET coating. Heat dissipation device B is paired with temperature control device B and is installed under the conveyor rollers of temperature control device B to cool the conveyor rollers and the PET coating after molding the 3D graphic. Heat dissipation device C is paired with temperature control device C and is installed under the conveyor rollers of temperature control device C to cool the conveyor rollers and the naked-eye 3D graphic after paper coating.

[0021] The rotating heat sink is designed to address the impact of continuous temperature rise during the coating process on the micro / nano structure of the graphic element molding, thereby improving the shape stability and levitation effect of the 3D graphic elements. It incorporates an auxiliary pad roller under the nickel roller graphic element molding as a rotating heat sink. This rotating heat sink includes a stainless steel roller, an aluminum ring-bladed cylinder, a central shaft, a fan integrated frame, multiple fans, transmission gears, bearings, and bearing seats. It functions as an auxiliary pad roller for the nickel roller graphic element molding and also features simultaneous rotation and heat dissipation, providing continuous cooling for the PET base film and PET coating. This prevents the transparency of the PET coating from decreasing due to the sustained high temperature of the PET coating and also protects and stabilizes the 3D micro / nano graphic element structure of the coating.

[0022] The invention is further characterized in that: the naked-eye 3D graphic transfer system integrates PET coating process, graphic molding process, roller cooling conveying process, aluminizing process, paper covering process, and finished product winding process into a single production line for the synchronous production of naked-eye 3D graphic products; in particular, the roller cooling conveying process solves the temperature connection problem between the graphic molding process and the aluminizing process, playing a key process connection role, thus making the technology of integrating PET coating process, graphic molding process, roller cooling conveying process, aluminizing process, paper covering process, and finished product winding process into a single production line practical and feasible, effectively avoiding the cost of handling semi-finished products between processes and the damage to semi-finished products caused by handling.

[0023] The roller cooling and conveying process includes a roller cooling conveyor, which introduces the PET coating and PET after roller pressing. Four rotating heat sinks dissipate heat from the PET coating and PET with micro / nano-structured elements, buffering the cooling time and temperature drop process. The cooled and shaped semi-finished product is then sent to the aluminizing equipment for further processing. The roller cooling conveyor includes a main frame, four rotating heat sinks, and multiple conveyor rollers (n). A motor and motor-driven gears drive a transmission chain, which in turn drives the four rotating heat sinks. The semi-finished product receives cooling and shaping through the multiple conveyor rollers (n) and the four rotating heat sinks.

[0024] The beneficial effects of this invention are:

[0025] 1. Because this invention uses suspended primitive photolithography design and nickel roller primitive molding technology to print 3D primitive products, it avoids the limitations of existing technologies that rely on small-format cylindrical lens grating film materials. It can achieve a 3D primitive product size of 600*600mm, solving the problem that existing technologies can only produce 3D primitive products with a maximum size of 200*200mm and a thickness of only 12-20um, failing to meet the needs of large-format and multi-layered suspended primitive effects. This increases the size of 3D primitive products, expands application areas, increases the market, and brings immeasurable benefits to enterprises and industries.

[0026] 2. Because the photolithography design software of this invention has a 3D primitive preview program, it can preview the designed and edited 3D primitives in a timely manner and make timely and convenient corrections and modifications. Therefore, it greatly improves the efficiency of photolithography design and editing, thereby improving the quality and production efficiency of naked-eye 3D primitive products, reducing production costs, saving energy, and reducing indirect pollution to the environment. It can bring immeasurable beneficial effects to the industry, the country, and society.

[0027] 3. By integrating PET coating, graphic molding, roller cooling and conveying, metallization, paper covering, and finished product winding into a single production line, the production cost of naked-eye 3D graphic products is greatly reduced, energy is saved, and indirect environmental pollution is reduced, bringing immeasurable benefits to the industry, the country, and society.

[0028] 4. Due to the functions of the temperature control device A, heat dissipation device A, temperature control device B, heat dissipation device B, rotating radiator, roller cooling conveyor, temperature control device C, and heat dissipation device C of the present invention, the defects of low transparency and easy yellowing or whitening of naked-eye 3D graphic elements caused by multi-process integrated production are avoided. Thus, the quality of naked-eye 3D graphic elements produced synchronously on a single line by integrating multiple processes is guaranteed. This solves the pain point technical problem in this field, fills the gap in this technology at home and abroad, leads the industry's technological innovation, promotes the technological development of the naked-eye 3D graphic element production industry, and brings immeasurable beneficial effects to this industry.

[0029] 5. Because the roller cooling and conveying process of the present invention solves the buffering and connection problem between the graphic molding process and the aluminizing process, it can integrate the PET coating process, graphic molding process, roller cooling and conveying process, aluminizing process, paper covering process, and finished product winding process into a single line for synchronous production. This can save production personnel, save electricity, and save time, thereby achieving the beneficial effects of saving production costs and improving production efficiency and benefits.

[0047] Implementation plan:

[0048] exist Figure 1 A method for printing suspended naked-eye 3D graphics and its integrated production equipment are disclosed, comprising a printing system including a PET base film, PET coating, temperature control device A, heat dissipation device A, graphics molding, rotating heat sink, temperature control device B, heat dissipation device B, roller cooling conveyor, aluminizing, adhesive coating, paper covering, temperature control device C, heat dissipation device C, naked-eye 3D graphics product, and finished product winding; the photolithography of the 3D graphics includes planar image design, suspended graphics photolithography design, photolithography, development, electroforming nickel roller, and nickel roller graphics molding; characterized in that: the P The ET base film is coated using a PET coating process, then temperature-controlled and shaped using temperature control equipment A and heat dissipation device A, followed by micro / nano 3D graphic structure molding using graphic molding and rotating heat sink, then temperature-controlled and shaped again using temperature control equipment B and heat dissipation device B, then further cooled and stabilized using a roller cooling process, then aluminum plating, then adhesive coating, then paper covering, then drying using temperature control equipment C and heat dissipation stabilization using heat dissipation device C, finally producing a naked-eye 3D graphic product, and finally the finished product is rolled up; the PET base film coating process and the aluminum plating process are connected to the same production line.

[0049] The graphic element molding process involves synchronous rolling and pressing of a nickel roller graphic element mold and a rotating heat sink.

[0050] The nickel roller pattern die is manufactured through a process of planar image design, suspended pattern photolithography design, photolithography, development, and electroforming nickel rollers; the nickel roller pattern die device is located in the printing system.

[0051] exist Figure 2 In the process described above, the lithographic design process for the suspended primitives in naked-eye 3D is as follows: importing a two-dimensional image—designing a suspended primitive layer—editing the depth of field of a suspended primitive—setting a raster—editing the scene of a suspended primitive—exporting lithographic data; that is, using lithographic design software to import the designed two-dimensional image, perform lithographic design and editing, and export the designed and edited lithographic data.

[0052] The name of the photolithography design software is: Photolithography Design;

[0053] The photolithography design software includes gradient dynamic mode, relief mode, 3D floating mode, and preview effect mode;

[0054] The menu of the photolithography design software includes "Hologram", "Layer", "Options", "Help", "Show Ruler", "Show Outline", "Single Layer Move", "Entire Layer Move", "Crop Selection", "Object", "Auto Snap", "Guidelines", and "Power".

[0055] Specific steps and operations for photolithography design:

[0056] Step a. Open the "Photolithography Design" software, click the "Project" menu drop-down and then click "Import" to import the 2D image; select the required 2D image file, click "Select" in the dialog box, after successful import, click the "Project" menu again, select the submenu "Save", enter a new name for the photolithography design in the dialog box, and save it as a .dkx file;

[0057] Step b1. Click the "Layers" menu to set the 3D floating upper layer; 1. Select some of the 2D primitives on the screen and click the top and bottom arrows to set them as the upper layer; 2. Click the "3D Floating" menu, select "Layer Depth of Field Settings", and set the value to 1-20. The layer depth of field setting value of 1-20 represents the actual depth of the lithographic transparent body between -20um and -60um, and 1 unit of the setting value is equivalent to 2um; when this setting value is set to 20, the primitive is displayed at the highest height on the upper layer of the transparent body, and when this setting value is set to 1, the primitive is displayed at the lowest height on the upper layer of the transparent body; set it arbitrarily within the adjustment range of "0~10", and the "Measured Depth" value is adjusted in units of "1". When this value is set to "10", the depth effect is the best. 3. Primitive raster settings: Click the "Bitmap List" menu to set the raster form of the upper layer. The raster form setting options are: "Raster Column", "Raster Sphere", etc. "No raster"; Select "Raster bar", then click "Raster bar diameter" in the bitmap list menu and set the raster bar diameter to 5-10um; After completing this setting, click "Save" in the main menu;

[0058] Step b2. Click the "Layers" menu to set the 3D floating middle layer; 1. Select some of the 2D primitives on the screen and set them as the middle layer; 2. Middle layer depth of field setting: Click the "Zoom System" menu, select "Depth of Field Setting," and set the value to 1-20. The layer depth of field setting value of 1-20 represents the actual depth of the lithographic lens between -60um and -100um, and 1 unit of the setting value is equivalent to 2um; when this setting value is set to 20, the primitive is displayed at the highest height of the middle layer of the lens; when this setting value is set to 1, the primitive is displayed at the lowest height of the middle layer of the lens; when this setting value is set to 10, the primitive is displayed at the most suitable height of the middle layer of the lens; the "Measured Depth" value is adjusted in units of "1," and the depth effect is best when the value is set to "1"; 3. Primitive raster setting: Click the "Bitmap List" menu to set the raster form of the upper layer. The raster form setting options are: "Raster Column," "Raster Sphere," etc. "No raster"; Select "Raster bar", then click "Raster bar diameter" in the bitmap list menu and set the raster bar diameter to 5-10um; After completing this setting, click "Save" in the main menu;

[0059] Step b3. Click the "Layers" menu to set the 3D floating lower layer; 1. Select some of the 2D primitives on the screen and set them as the lower layer; 2. Lower layer depth setting: Click the "Zoom System" menu to set the lower layer depth and set the value to 1-10. The lower layer depth setting value of 1-10 represents the actual depth of the lithographic transparent body between -100um and -120um, and 1 unit of the setting value is equivalent to 2um; when this setting value is set to 10, the primitives displayed in the lower layer of the transparent body have the deepest primitive depth, and when this setting value is set to 1, the primitives displayed in the lower layer of the transparent body have the highest primitive height; set arbitrarily within the adjustment range of "0~10", and adjust the measured depth value in units of "1". When we set the value to "10", the depth effect is the best; 3. Primitive raster setting: Click the "Bitmap List" menu to set the raster form of the upper layer. The raster form setting options are: "Raster Column", "Raster Sphere", etc. "No raster"; Select "Raster Pole", then click "Raster Pole Diameter" in the Bitmap list menu and set the raster pole diameter to 5-10um; 4. Set the primitive surface, click the Bitmap menu to set the primitive surface type, select "Concave Surface" or "Convex Surface", set the concavity / convexity value, click the "Raster" menu in the Bitmap menu to set the concavity value to -50 to -30um or the convex value to -50 to -30um; After this setting is completed, click "Save" in the main menu; In order to achieve a visually flowing image effect, we need to set the "Distant View" value below the "Measured Depth" value. The value setting range of this function is between 0 and 5, with each "0.5" as the adjustment unit. When we set the data to "2", the visually flowing image effect of the pattern is the best.

[0060] b4: Click on the diameter value in the "Floating" menu and set it to 50, then press Enter on your keyboard to confirm.

[0061] The gradient dynamic mode setting involves selecting the "gradient dynamic mode" for the lithographically designed primitives and setting the visual angle range, which is between -90 and 90 degrees. This setting allows for arbitrary adjustment of the visual angle between -90 and 90 degrees based on the graphics and the designer's thinking, with the optimal visual angle preferably set between -75 and 75 degrees.

[0062] Step c. Click on the Pattern menu settings in the "Floating" menu: Click on the quadrilateral or hexagonal pattern under the Pattern menu to set the texture of the 3D floating and flowing pattern;

[0063] Step d. Select the emboss effect settings. This effect is a wide-view fine-sculpting effect, usually without color, presenting a single bright metallic luster. The lithography software calculates the fine-sculpted surface through the project manager, performs micron-level equal-height layering and trimming on the fine-sculpted surface, and concentrates each surface segment into one layer, presenting a raised metallic luster, visible only with a magnifying glass of at least 50x. After importing the designed PNG format fine-sculpting pattern into the lithography software, click the "Fine-Sculpting" mode effect. Under "Add Image," you will see the mode effect parameter settings. We can control the "Power" value to determine the number of outlines (layers) of the fine-sculpted image. The setting range is "1~20." The larger the fine-sculpted pattern, the higher the "Power" value, with a maximum setting of 20. The smaller the fine-sculpted pattern, the lower the "Power" value, with a minimum value of "1." When we set the "Power" value to "20," the fine-sculpting effect is better, and the metallic texture is more prominent. At magnification, a larger outline range produces the best effect.

[0064] Step e. Preview and Modify: Click the "Preview Effect" menu to preview the 3D primitive effect of the designed and edited lithography file. Then, check and correct errors based on the previewed 3D primitives. Apply the corrected errors to the lithography design software "Light Design" for further modification. Preview again after modification until the previewed lithography design and editing are satisfactory, then proceed to the next step, "Data Export." The purpose of "Preview Effect" is to enable lithography designers to promptly and accurately check for errors in the lithography design and editing, avoiding the current technology where errors are only discovered after lithography, thus avoiding the lithography experiment costs incurred by discovering errors after lithography. It also greatly improves the production efficiency, product quality, and production benefits of the lithography process.
