[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1 This embodiment provides an integrated fabrication device for three-dimensional biomimetic optical functional materials, including a printing unit 1, a gas filter structure 10, a vapor deposition unit 14, a control unit 26, and a drive unit 28. The printing unit 1 is a square box shape, and a partition is provided inside the printing unit 1, dividing the printing unit 1 into two sections. A printing chamber 3 is provided on the upper side of the partition, and a drive chamber 31 is provided on the lower side of the partition. A joint surface 7 is provided on the right end of the printing unit 1, and the vapor deposition unit 14 is interference-fitted to the printing unit 1 through the joint surface 7. The printing unit 1 and the vapor deposition unit 14 are interference-fitted to each other through the joint surface 7, and after connection, the two independent unit boxes become one box. This design enhances the overall compactness of the device. The vapor deposition unit 14 consists of a hot vapor deposition chamber 15 and a control chamber 24, with the hot vapor deposition chamber 15 located above the control chamber 24. The inner wall of the hot vapor deposition chamber 15 and the surface of each internal unit are coated with a heat insulation layer to ensure the uniformity of the model vapor deposition. The heat insulation layer can withstand temperatures up to 300℃. A second sensor door 8 is installed on the left side wall of the hot vapor deposition chamber 15. A model fixing structure 18 is installed inside the hot vapor deposition chamber 15, and a feeding structure 20 is installed on the lower right side of the hot vapor deposition chamber 15. Both the first sensor door 6 and the second sensor door 8 consist of a door rail, an infrared sensor, a position sensor, a data collector, and a sensor door. The door rail is secured by a locking mechanism. Screws are embedded in the side wall of the housing, and a pulley slot is fixedly installed at the top of the door track. The first sensor door 6 and the second sensor door 8 are connected to the pulley slot via S-shaped clips, with a pulley seat and a pulley. Both sides of the first sensor door 6 and the second sensor door 8 have embedded grooves, and sealing strips are installed inside the embedded grooves. The pulley slots can prevent the sensor doors from deviating from the track or becoming unstable. The principle and usage process of the first sensor door 6 and the second sensor door 8 are the same as existing technologies, and will not be repeated here. In actual use, a biomimetic template of a metal nanostructure made of biomimetic optical functional material is first created using a computer, and then the model template is printed using the 3D printing unit 1. In this example, the wings of the Morpho luminifera butterfly were selected as the biological template for preparing the three-dimensional biomimetic optical functional material metal nanostructure. The metals used for vapor deposition were gold and palladium. The top and bottom scales of the Morpho luminifera butterfly have similar structures. These scales are arranged alternately, similar to roof tiles, which can be regarded as a unique single-layer scale arrangement. The computer constructs a three-dimensional model of the butterfly's double-layer scales and then outputs it to the receiver of the 3D printing chamber 3. The receiver of the 3D printing chamber 3 transmits the signal to the printing module. The printing module receives the instruction and begins to finely carve the layers one by one. After the printing is completed, the control module of the transfer robotic arm 5 receives the instruction and the transfer robotic arm 5 begins the transfer work.

[0026] A control panel 2 is installed on the left outer wall of the printing chamber 3. A fixed shaft 4 is installed inside the printing chamber 3, and a transfer robotic arm 5 is mounted on the fixed shaft 4. A first sensor door 6 is installed on the right side wall of the printing chamber 3. Suction cups are installed at both ends of the fixed shaft 4, and the fixed shaft 4 is placed inside the printing chamber 3 via the suction cups. The transfer robotic arm 5 consists of a hydraulic telescopic shaft and a robotic arm. The robotic arm of the transfer robotic arm 5 consists of a ring clamp and a detachable scissor tray. During the transfer operation, the model is identified, the transfer robotic arm 5 rotates and shifts, and the robotic arm picks up the model for transfer. At this time, the ring clamp of the robotic arm unfolds, and the detachable scissor tray is in a detached state. The telescopic shaft drives the robotic arm to push and move the model onto the detachable scissor tray. The tray closes, and the ring clamp opens. The caliper locks, and the transfer robotic arm 5 moves forward according to the trajectory command. When it reaches the first sensor door 6, the transfer robotic arm 5 waits. The infrared sensors and position sensors of the first sensor door 6 and the second sensor door 8 send signals to the controller, and the first sensor door 6 and the second sensor door 8 open. The transfer robotic arm 5 continues to move forward according to the set trajectory. When the transfer robotic arm 5 reaches directly above the model fixing structure 18, the transfer robotic arm 5 stops moving forward, and the robot arm and telescopic shaft start to operate. When the bottom of the detachable scissor tray of the robot arm makes smooth contact with the platform 1802, the detachable scissor tray and the ring caliper slowly open, the robot arm slowly withdraws, and then the transfer robotic arm 5 returns to its original position, and the first sensor door 6 and the second sensor door 8 close.

[0027] The drive chamber 31 consists of a second backup battery 27, a drive unit 28, an external power cord 29, and a connection interface 30. The drive chamber 31 has an installation slot at its bottom, and the drive unit 28 is installed inside the installation slot. The drive unit consists of an external power supply, a motor, a frequency converter, a controller, and a wired control board. The external power cord 29 is connected to the left side of the drive unit 28. The connection interface 30 includes an external power slot and a wired control interface. The controller is connected to the drive unit 28 through the external power socket. The printing chamber 3, the transfer robotic arm 5, and the first sensor door 6 are all integrated into the main switch of the control panel 2 via the wired control board and connected to the external power supply.

[0028] Example 2

[0029] Reference Figures 1-2This embodiment is based on the previous embodiment, but differs in that a vacuum generator 9 is installed at the left end of the thermal evaporation chamber 15. A evaporation top cover 13 and an evaporation inner cover 16 are provided on the top of the thermal evaporation chamber 15. Sealing strips are provided on the four edges of the evaporation top cover 13. The evaporation inner cover 16 has a three-way hook design, and its upper surface is wedge-shaped. The evaporation inner cover 16 is recessed 1-3 cm below the horizontal plane of the evaporation top cover 13. Simultaneously, the tops of both sides of the evaporation inner cover 16 are flush with the inner edge of the evaporation top cover 13. The three-way hook surfaces of the evaporation inner cover 16 are flush with... The vertical plane is inclined at 10°-15°. The inner wall of its three-way hanging ear is connected to the inner wall of the hot evaporation chamber with a wedge-shaped transition fit. The switch of the evaporation top cover 13 is an internal snap-on mechanical switch, and a circular mesh is installed at the center of the evaporation top cover 13. The evaporation top cover 13 and the evaporation inner cover 16 are fixed by a one-way end hinge. A gas filter structure 10 is provided on the lower side of the evaporation top cover 13. The gas filter structure 10 consists of a telescopic tube 11, a gas filter 12, an infrared sensor, a relay interlock, a built-in motor, a drive shaft, and rectangular blades. The telescopic tube 11 is installed in the middle of the lower end of the evaporation top cover 13, and the telescopic tube 11 extends... A gas filter 12 is installed at the lower end of the shrink tube 11, penetrating the vapor deposition top cover 13. An infrared sensor and relay interlock are installed inside the gas filter 12. A rectangular groove is formed in the middle of the lower end of the gas filter 12, and a drive shaft is installed inside the rectangular groove. Rectangular blades are installed on the drive shaft. A built-in motor is installed inside the gas filter 12, and the output end of the built-in motor is connected to the drive shaft. Two laser infrared scanners 17 are installed on the inner wall of the hot vapor deposition chamber 15, arranged circumferentially and staggered vertically on the inner wall of the hot vapor deposition chamber 15. The principle and usage of this gas filter 12 are the same as those of the existing technology, and will not be repeated here. The device uses the gas filter 12 to ensure the airtightness of the vapor deposition chamber 15. After the vapor deposition begins, when a certain amount of gas is vaporized from metal, the flow sensor in the gas filter 12 senses it and transmits a signal to the control unit 26. The control unit 26 instructs the drive shaft of the gas filter 12 to move downward first, so that the rectangular blades of the gas filter 12 reach the designated position. The rectangular blades start to rotate and drive the vapor deposition airflow to surround the model, ensuring the uniformity of the vapor deposition of the model.

[0030] Example 3

[0031] Reference Figures 2-4This embodiment is based on the previous embodiment, but differs in that the model fixing structure 18 includes a telescopic rod 1801, a platform 1802, an electromagnet 1803, a base 1804, and a replacement groove 1805. Several telescopic rods 1801 are circumferentially installed on the inner wall of the hot-dip evaporation chamber 15, and there are three sets of telescopic rods 1801. The other end of each telescopic rod 1801 is connected to the base 1804. A model cover is provided on the upper end of the base 1804, and the model cover is a hemispherical telescopic door. A platform 1802 is provided in the middle of the upper end of the base 1804. The size of the model placed on the platform 1802 and the model cover can be controlled within the range of 10*10*10cm³, and the specific size can be modified according to the actual situation. An electromagnet 1803 is provided in the middle of the upper end of the platform 1802, and the upper end of the platform 1802... Replacement grooves 1805 are provided on both the left and right sides to facilitate replacement. When the model is placed on the platform 1802, the electromagnet 1803 starts to work, adsorbing the platform 1802 onto the base 1804 to ensure the model is deposited stably. Then, the model cover is installed on the base 1804 and opened and closed electrically. The model cover material is slightly elastic. When the first vapor deposition of the model is completed, the feed chamber door 2003 needs to be opened for secondary filling. Before opening the feed chamber door 2003, the model cover pillow model needs to be opened to put the model in a sealed space. When the bottom of the tray makes stable contact with the platform 1802, the electromagnet 1803 of the model fixing structure 18 is turned on, adsorbing the platform 1802 tightly into the replacement groove 1805. At this time, the relay interlock of the gas filter 12 is also in the closed state.

[0032] The lower end of the thermal evaporation chamber 15 is equipped with an evaporation device 22, and the upper middle part of the evaporation device 22 is equipped with an explosion-proof heater 23. The upper end of the explosion-proof heater 23 is equipped with a metal reaction vessel 19. A grooved connecting rod 21 is welded to the right side wall of the metal reaction vessel 19. The grooved connecting rod 21 is inclined, with the inner side lower than the outer side, so that the material can directly reach the metal reaction vessel 19. Sliding rods 2101 are provided on both the front and rear sides of the grooved connecting rod 21, and the inclination angle of the sliding rods 2101 is the same as that of the grooved connecting rod 21. Several round rods 2102 are provided between the sliding rods 2101 and the grooved connecting rod 21. A pressing and bouncing device 2103 is provided on the right end of the sliding rod 2101, and the left end of the grooved connecting rod 21 extends into the interior of the metal reaction vessel 19. The internal space of the evaporation unit 14 is separated by the base of the evaporation device 22. The thermal evaporation chamber 15 is the space for model evaporation and model metal deposition.

[0033] The feeding structure 20 includes a slide rail 2001, a pulley 2002, a feeding chamber door 2003, a feeding window 2004, and a handle 2005. A feeding trough is provided on the lower right side of the hot-dip evaporation chamber 15. Two slide rails 2001 are symmetrically arranged at both ends of the feeding trough. Pulleys 2002 are slidably connected inside each of the two slide rails 2001. A feeding chamber door 2003 is located between the two pulleys 2002. A feeding window 2004 is hinged inside the feeding chamber door 2003, and a handle 2005 is provided on the right end of the feeding window 2004 to facilitate the opening of the feeding window 2004 for material feeding. A control unit 26 is installed inside the control room 24, and a first backup battery 25 is installed on the side wall of the control unit 26. A second sensor door 8 and a vacuum generator are also present. The generator 9, gas filter 12, vapor deposition equipment 22, feed door 2003, and control unit 26 are all integrated into the control panel 2 via wires and connected to an external power supply. While the transfer robotic arm 5 transfers the model, metal feeding also occurs simultaneously. Depending on the size of the metal, the system selects whether to activate the feed door 2003 or open the feed window 2004. In this example, since the vapor-deposited metals are gold and titanium, both granular, only the feed window 2004 needs to be opened. The controller issues a command, and the feed window 2004 opens. First, the first layer of plating metal, titanium, is placed in. The titanium granules slowly roll along the grooved connecting rod 21 into the metal reaction vessel 19. After feeding is complete, the laser infrared sensor 17 on the inner wall of the hot vapor deposition chamber 15 begins scanning and monitoring the grooved connecting rod 21. After scanning to check for any missing gold particles, the feed door 2003 and feed window 2004 are closed. The controller program then checks again whether all doors, sensor doors, and power-off interlocks are closed. After all checks are completed, the vacuum generator 9 is turned on, and the thermal evaporation chamber 15 is transformed into a vacuum environment. The explosion-proof heater 23 receives the heating command signal and begins to work. When the specified temperature is reached, the explosion-proof heater 23 switches to constant temperature mode. Constant temperature mode means maintaining a constant set temperature. The metal target material is heated and evaporated, and a large number of metal atoms vaporize and escape from the surface of the target material. The vapor flow reaches the surface of the model substrate, adsorbs, aggregates, nucleates, and grows to form a solid thin layer. By controlling the evaporation rate and evaporation time, the thickness of the deposited metal can be controlled. To measure the deposition thickness, at the start of metal target evaporation, laser infrared scanners 17, arranged circumferentially in a crisscross pattern on the inner wall of the thermal evaporation chamber 15, begin to comprehensively monitor the metal thickness of each scale module on the model surface. The metal coating thickness can be read in real time through the control panel of the control unit 26. In this example, a second evaporation is required. The first evaporation uses thermal evaporation to deposit a 2nm thick titanium layer on the butterfly wing model as an adhesion layer. When the coating reaches the specified thickness, the model cover on the clamping device opens, covering the model in a sealed space. The explosion-proof heater 23 stops working, and then the feed chamber door 2003 is opened. The grooved connecting rod 21 is controlled to automatically eject the metal reaction vessel 19, cleaning the residual titanium in the metal reaction vessel 19. Gold is then added to the metal reaction vessel 19.The grooved connecting rod device 21 slides back to its original position, closing the feed chamber door 2003. Then, the vacuum generator 9 is turned on. Once the thermal evaporation chamber 15 becomes a vacuum environment, the evaporation equipment 22 restarts and continues to deposit gold of a specific thickness to obtain the desired sample. At this point, the evaporation process ends, and the gas filter 12 begins filtration. During the evaporation process, the metal deposition rate is set to 0.5 nm•s. -1 By controlling the metal deposition time, the coating thickness can be adjusted relatively easily.
