[0039] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0042] With the continuous improvement of laser equipment performance and the gradual reduction of costs, more and more industries have developed a strong interest in liquid phase laser technology, hoping to use nanomaterials prepared by liquid phase lasers to manufacture high-value-added products such as high-performance catalysts, battery materials, functional coatings, and biomedical applications. Although laser technology has mature applications in industrial mass production, the industrial application of liquid phase laser technology in nanoparticle preparation is still in its early stages, not yet fully mature, and large-scale production is not yet widespread. Therefore, designing and constructing dedicated liquid phase laser large-scale production equipment for nanoparticle production has become a key issue to be addressed.

[0043] In existing technologies, there exists a high-power, high-frequency ultrafast laser. Based on this ultrafast laser, the yield of liquid-phase laser ablation can reach 4 g / h, and the continuous synthesis of nanoparticles has been successfully achieved, approaching the near-industrial-scale production yield of metal nanoparticles. These achievements indicate that liquid-phase laser technology is gradually moving from the laboratory to industrialization. However, existing technologies mainly focus on increasing the power and frequency of the laser, and such upgrades are usually accompanied by a significant increase in equipment costs.

[0044] In the overall design of liquid phase laser mass production equipment, in addition to improving laser performance, the optimization and coordination of back-end supporting facilities are equally crucial. While laser performance directly affects the fabrication efficiency of nanoparticles, multiple factors during the ablation process, such as the target surface condition, ablation path, target utilization efficiency, as well as the effective irradiation area, irradiation uniformity, and cooling rate during irradiation, also significantly impact fabrication efficiency and product quality. Given the relatively mature state of current laser manufacturing technology, the optimization and matching of back-end supporting facilities for liquid phase laser mass production equipment has become a key factor in ensuring production efficiency, stability, and product quality.

[0045] In existing technologies, there exists a liquid phase laser irradiation system with an automatically changing irradiation tank, capable of continuous irradiation under large-scale control, thus significantly improving preparation efficiency and effectiveness. However, current technologies still lack optimization and matching in other aspects of the back-end supporting facilities for large-scale liquid phase laser production equipment. Large-scale liquid phase laser production equipment needs to possess high efficiency and continuity, ease of operation, and modular integration to reduce labor costs and improve production flexibility. Of course, production safety is also a crucial consideration. Ideally, such equipment should simultaneously support production based on liquid phase laser ablation technology and production based on liquid phase laser irradiation technology.

[0046] In one embodiment, such as Figure 1 and Figure 2 As shown, a liquid phase laser mass production equipment 10 includes: a sample cell 102, a laser (Figure 1 (Not shown) and temperature control pot 104.

[0047] The sample cell 102 is used to hold the reaction solution and the target material.

[0048] The irradiation area of ​​the laser includes the location area of ​​the target material; the laser is used to provide a laser beam to process the product to be prepared into nanoparticle products.

[0049] The temperature control pot 104 has a groove for holding the sample cell 102, and there is a gap between the inner wall of the temperature control pot 104 and the outer wall of the sample cell 102, and the gap is filled with heat-insulating material.

[0050] Temperature control of the product being processed allows for adjustment of the morphology and size of the generated nanoparticles. Specifically, processing the product at room temperature yields nanoscale and / or sub-10 nanometer-sized particles, which are spherical and / or near-spherical. Processing the product above room temperature yields nanoscale and / or sub-10 nanometer-sized particles, exhibiting multi-level morphological variations. Processing the product below 0°C yields sub-nanometer and / or sub-10 nanometer-sized particles, which are clustered and / or single-atom in shape.

[0051] Because the laser beam emitted by the laser causes temperature changes in the reaction solution, target material, and sample cell 102, resulting in temperature variations in the processing steps, the temperature of the sample cell 102, as well as the reaction solution and target material within it, can be controlled using insulation materials. Specifically, injecting liquid or solid insulation materials of different temperatures into the gap between the inner wall of the temperature-controlled pot 104 and the outer wall of the sample cell 102 can maintain the temperature of the sample cell 102 within a certain range, thereby achieving temperature control during the processing steps. The insulation material can be water, ice, hot oil, dry ice, liquid nitrogen, or other materials that facilitate temperature control, and will not be elaborated further here.

[0052] It should be noted that, although Figure 1 Both the intermediate sample cell 102 and the temperature control pot 104 are hexahedrons without a top surface and with their interiors hollowed out, but Figure 1 The shapes shown are for illustrative purposes only and do not specifically limit the exact shapes of the sample cell 102 and the temperature control pot 104. In one embodiment, as shown... Figure 2 As shown, the temperature control pot 104 can be a cylinder without a top surface and with its interior hollowed out. Furthermore, the shape of the temperature control pot 104 can be selected according to the shape of the sample cell 102 to match the shape of the sample cell 102 and improve the temperature control effect.

[0053] The aforementioned liquid phase laser mass production equipment 10 includes a sample cell 102, a laser, and a temperature-controlled pot 104. The temperature-controlled pot 104 controls the temperature of the sample cell 102, the reaction solution within it, and the target material, thereby reducing the impact of the laser beam emitted by the laser on the processing steps, resulting in a higher yield of target products. Furthermore, the gap between the inner wall of the temperature-controlled pot 104 and the outer wall of the sample cell 102 can be filled with insulating material. This insulating material's heat preservation function allows for temperature control of the sample cell 102, the reaction solution within it, and the target material, further improving the temperature control effect and performance of the liquid phase laser mass production equipment 10.

[0054] In one embodiment, the pot wall of the temperature-controlled pot 104 is made of heat-insulating material to enhance the heat preservation effect of the liquid phase laser mass production equipment 10.

[0055] In one embodiment, the temperature-controlled pot 104 has an injection port 1042, wherein the injection port 1042 is used to inject heat-insulating material.

[0056] In one embodiment, such as Figure 2 and Figure 3 (a) and Figure 3 As shown in (b), the above-mentioned liquid phase laser mass production equipment 10 also includes: a rotary table 106.

[0057] The rotating stage 106 is used to support the temperature-controlled pot 104 so as to drive the temperature-controlled pot 104 to rotate relative to the laser beam generated by the laser.

[0058] The laser beam generated by the laser irradiates the sample cell 102. Before the rotating stage 106 is assembled, the laser beam generated by the laser will continuously irradiate a certain area of ​​the sample cell 102 (see...). Figure 3 (The dark dots in (a) indicate that prolonged concentrated irradiation by the laser beam can cause localized overheating or even excessive irradiation, and the laser irradiation received by the target material is not uniform. After assembling the rotating stage 106, the effective irradiation area of ​​the laser beam is significantly increased, and the projected spot of the laser beam forms a ring-shaped coverage within the sample cell 102 (see [reference]). Figure 3 The dark ring markings in (b) significantly increase the effective irradiation area of ​​the laser irradiation, reduce the possibility of over-irradiation, thereby ensuring that the target material can receive the laser action uniformly during the irradiation process and accelerate the cooling process, thus improving the large-scale preparation capability and production efficiency of liquid phase laser irradiation.

[0059] For example, under the same experimental conditions such as laser power, laser beam projection spot, frequency, and precursor concentration, experiments have verified that 50 ml of nanoparticle product can be obtained before assembling the rotating stage 106; and more than 500 ml of nanoparticle product can be obtained after assembling the rotating stage 106. This demonstrates that the large-scale production capability of the liquid phase laser mass production equipment 10 equipped with the rotating stage 106 is significantly improved.

[0060] In one embodiment, such as Figure 2 As shown, the above-mentioned liquid phase laser mass production equipment 10 also includes: a placement platform 108.

[0061] The placement platform 108 is positioned between the temperature-controlled pot 104 and the rotating table 106, and is in contact with both the temperature-controlled pot 104 and the rotating table 106. The placement platform 108 is used to support the temperature-controlled pot 104.

[0062] By placing the platform 108 to support the temperature-controlled pot 104, friction can be increased, thereby preventing the rotating table 106 from rotating and throwing the temperature-controlled pot 104 out.

[0063] In one embodiment, the temperature-controlled pot 104 is fixed on the placement platform 108 to increase the stability of the temperature-controlled pot 104.

[0064] In one embodiment, such as Figure 2 As shown, the above-mentioned liquid phase laser mass production equipment 10 also includes: a thermometer 110.

[0065] The thermometer 110 is placed inside the temperature-controlled pot 104.

[0066] The temperature of the temperature control pot 104 can be monitored in real time by measuring the temperature of thermometer 110, which allows staff to easily add or remove insulation material.

[0067] In one embodiment, such as Figure 2 As shown, the above-mentioned liquid phase laser mass production equipment 10 also includes: a magnetic stirrer 112 and a magnetic particle 114.

[0068] The magnetic stirrer 112 is used to support the temperature-controlled pot 104.

[0069] The magnetic particle 114 is placed inside the sample cell 102, and the size of the magnetic particle 114 is positively correlated with the diameter of the sample cell 102. The magnetic particle 114 is used to stir under the magnetic force of the magnetic stirrer 112.

[0070] The combined use of magnetic stirrer 112 and magnetic particle 114 can stir the target material in sample cell 102 so that the laser beam can radiate the target material uniformly, thereby improving the efficiency and uniformity of preparing nanoparticle products in liquid phase laser mass production equipment 10.

[0071] Irradiation efficiency and preparation scale can be improved by increasing the height and width of the sample cell 102. Simultaneously, the stirring magnet 114 is optimized to a larger size, thus possessing stronger stirring capabilities to meet the stirring requirements of the large-volume sample cell 102. The size of the magnet 114 is positively correlated with the aperture size of the sample cell 102. Specifically, a sample cell 102 with a 2.5cm aperture can be paired with a magnet 114 approximately 2cm long, and a sample cell 102 with a 7cm aperture can be paired with a 5-6cm octagonal magnet to achieve thorough stirring. Furthermore, the magnet 114 can be an octagonal magnet.

[0072] In one embodiment, the liquid phase laser mass production equipment 10 further includes: an adjustable focus light guide arm 116.

[0073] The adjustable focus light guide arm 116 is disposed in the optical path between the laser and the sample cell 102, and the adjustable focus light guide arm 116 is used to propagate the laser beam generated by the laser to the target material of the sample cell 102.

[0074] By moving the adjustable focus light guide arm 116 or adjusting the light outlet of the adjustable focus light guide arm 116, the radiation direction of the laser beam can be adjusted, thereby making it easy to move the laser beam to the initial irradiation position or initial melting position of the target material, ensuring the precise positioning of the laser beam and the target material.

[0075] In one embodiment, such as Figure 4 (a) and Figure 4 As shown in (b), the adjustable focusing light guide arm 116 includes a lens barrel 1162, a rotary button 1164, and a focusing lens 1166. Figure 4 (a) is a front view of the adjustable focus light guide arm 116. Figure 4 (b) is a cross-sectional view of the adjustable focus light guide arm 116.

[0076] Among them, the lens tube 1162 is used to fix the optical path.

[0077] The focusing lens 1166 is used to adjust the size of the projected spot of the laser beam when the rotary button 1164 is enabled.

[0078] By rotating the rotary button 1164, the length of the lens barrel 1162 is controlled, thereby changing the focal length of the focusing lens 1166 to alter the size of the projected laser beam spot. Simultaneously, the optical path is protected within the lens barrel 1162, preventing personal injury caused by laser beam deflection due to human error.

[0079] In one embodiment, such as Figure 4 (a) and Figure 4 As shown in (b), the above-mentioned liquid phase laser mass production equipment 10 also includes: a protective lens 118.

[0080] A protective lens 118 is disposed at the light outlet of the adjustable focus light guide arm 116. The protective lens 118 is a removable lens.

[0081] The size of the protective lens 118 matches the size of the light outlet of the adjustable focus light guide arm 116. The protective lens 118 can minimize the damage to the laser caused by liquid surface reflection light and liquid phase medium sputtering during the processing of the target material, effectively protecting the laser, reducing the laser maintenance cost, and extending the service life of the liquid phase laser mass production equipment 10.

[0082] In one embodiment, the liquid phase laser mass production equipment 10 further includes a sample displacement stage 120.

[0083] The sample displacement stage 120 is used to move the sample cell 102 so that the target material moves relative to the laser.

[0084] Prolonged concentrated laser beam irradiation at the same location can cause localized overheating and even excessive melting. The melting path of a small rotary displacement stage in traditional technology is as follows: Figure 5 As shown in (a), this small rotary displacement stage can only drive the sample cell 102 to rotate. Regardless of the size of the target material, the actual erosion path is only a circular area, which leads to repeated erosion by the laser pulse, affecting the erosion efficiency and the uniformity of nanoparticles.

[0085] like Figure 5 As shown in (b), this application provides a sample moving stage with a single-path melting process. This sample moving stage is a translational stage with a larger displacement space, capable of accommodating a larger sample pool 102. The larger sample pool 102 provides a larger melting area, allowing the sample pool 102 to hold more solution, thus enabling the processing of a large number of target materials. Furthermore, the single-path sample moving stage avoids repeated melting by the laser beam and improves target utilization and melting efficiency by precisely controlling the target moving path and speed.

[0086] In one embodiment, such as Figure 6 (a) and Figure 6 As shown in (b), the aforementioned liquid phase laser mass production equipment 10 also includes: an equipment body 122 and an optical module. Among them, Figure 6 (a) is a plan view of the liquid phase laser mass production equipment 10. Figure 6 (b) is a three-dimensional view of the liquid phase laser mass production equipment 10.

[0087] The accommodating cavity of the device body 122 has a baffle plate, dividing the accommodating cavity into a first chamber 1222 and a second chamber 1224, with the first chamber 1222 located above the second chamber 1224. This can be understood as the first chamber 1222 being located above the second chamber 1224 in the normal operating position of the liquid phase laser mass production equipment 10.

[0088] An optical module and a laser are disposed in the first chamber 1222, and a sample cell 102 is disposed in the second chamber 1224. The optical module is used to project the laser beam output by the laser through the light-transmitting area of ​​the barrier plate onto the sample cell 102.

[0089] The first chamber 1222 includes a third chamber 1222a and a fourth chamber 1222b. The third chamber 1222a houses the laser's power supply system, which is highly integrated, supports independent installation and replacement, and is compatible with various types of lasers. The fourth chamber 1222b houses the laser and an optical module, wherein the optical module is an adjustable beam reflection system, allowing users to adjust the optical path according to production needs, thereby achieving laser ablation or laser irradiation based on different wavelengths and types of laser beams.

[0090] In one embodiment, such as Figure 6 (a) and Figure 6 As shown in (b), the device body 122 has a sample inlet / outlet door 1226 on the side near the sample cell 102.

[0091] A separate sample inlet / outlet door 1226 can be designed on the device body 122 in the second chamber 1224 where the sample pool 102 is placed, so as to facilitate the placement and removal of the sample pool 102.

[0092] The laser and sample cell 102 are designed to be separated, so that the irradiation direction of the laser beam is effectively blocked by the panel, thereby ensuring the safety of the operating area.

[0093] In one embodiment, a separate cabinet door can be designed on the device body 122 in the first chamber 1222 where the laser is placed. This cabinet door can be a lockable cabinet door to enhance production safety and ensure stability during the production process.

[0094] In one embodiment, the liquid phase laser mass production equipment 10 further includes a water cooling system.

[0095] The water cooling system is used to cool the laser to prevent it from overheating.

[0096] The water cooling system can also cool the sample cell 102, the rotary table 106, and the sample displacement stage 120.

[0097] In one embodiment, such as Figure 6 (a) and Figure 6 As shown in (b), the device body 122 is provided with a water inlet 1228 for the water cooling system, and the device body 122 contains a water tank 1230 for the water cooling system. The water cooling system enables continuous and automated processing into nanoparticle products, avoiding the need to wait for the laser sample cell 102, the rotary stage 106, and the sample displacement stage 120 to cool down for a long time.

[0098] Furthermore, the water tank 1230 of the water cooling system can be located inside the second chamber 1224.

[0099] In one embodiment, the liquid phase laser mass production equipment 10 further includes a heat dissipation system.

[0100] The heat dissipation system is used to dissipate heat from the laser to prevent it from overheating.

[0101] The heat dissipation system can also dissipate heat for the sample cell 102, the rotary stage 106 and the sample displacement stage 120.

[0102] In one embodiment, such as Figure 6 (a) and Figure 6 As shown in (b), the above-mentioned liquid phase laser mass production equipment 10 also includes: pulley 1232.

[0103] The pulley 1232 is installed at the bottom of the equipment body 122 to facilitate the movement and adjustment of the position of the liquid phase laser mass production equipment 10, thereby adapting to flexible deployment in different production environments.

[0104] In one embodiment, such as Figure 6 (a) and Figure 6 As shown in (b), the above-mentioned liquid phase laser mass production equipment 10 also includes: a laser control system, a translation stage control system, and an external control panel 1234 for the platform.

[0105] Both the laser control system and the displacement stage control system are connected to the external control panel 1234 of the platform.

[0106] The platform's external control panel 1234 includes a laser control panel 1234a, a mobile control panel 1234b, and multiple operation buttons 1234c.

[0107] Operators can adjust the laser configuration parameters via the laser control panel 1234a, and adjust the ablation path of the sample displacement stage 120 via the moving control panel 1234b. Multiple operation buttons 1234c allow for one-button start, one-button stop, and emergency shutdown, enhancing the simplicity, intuitiveness, and convenience of the platform's interface. Therefore, after the product to be prepared is placed, operators only need to set appropriate laser parameters to start the production process.

[0108] In one embodiment, the volume and height of the aforementioned liquid laser mass production equipment 10 were reduced, making the liquid laser mass production equipment 10 more compact. The optimized height of the liquid laser mass production equipment 10 is 1567mm. Combined with the specific optical path structure of the laser, a multi-dimensional safety protection system was constructed, thereby ensuring that the operator's eye area is always outside the path of scattered light when standing or walking, reducing the risk of accidental injury from the laser beam and significantly improving operational safety.

[0109] The aforementioned liquid-phase laser mass production equipment 10 optimizes the target ablation device (including the sample displacement stage 120) in liquid-phase laser ablation technology, precisely controlling the target's movement path and speed, thereby improving laser ablation efficiency and target utilization. In liquid-phase laser irradiation technology, the equipment optimizes the uniform stirring device (including the rotating stage 106 and magnetic particle 114), significantly expanding the effective irradiation area of ​​the laser, reducing the risk of localized over-irradiation, ensuring the sample is uniformly subjected to the laser beam during irradiation, and improving the cooling efficiency at the laser irradiation location. The equipment can switch between laser ablation and laser irradiation modes by adjusting the optical path, making it suitable for producing various types of nanoparticle colloidal solutions. Overall, the liquid-phase laser mass production equipment 10 offers better performance, higher integration, smaller footprint, and higher production efficiency, meeting the requirements for safe and efficient large-scale production.
