Description

Technical Field

[0001] This invention relates to a multi-channel single-nozzle electrodeposition jet liquid beam 3D printing structure, belonging to the field of electrodeposition 3D printing technology. Background Technology

[0002] Electrodeposition 3D printing offers unique advantages in electronic and microelectronic device fabrication due to its ultra-high precision and resolution, enabling the fabrication of micron-level (and even nanon-level) structures. Taking micro-flexible circuit boards as an example, traditional processes require multiple steps such as photolithography, etching, and lamination to build circuitry on a planar substrate, making it difficult to achieve cross-layer three-dimensional interconnections. Furthermore, high-temperature processes can easily lead to deformation or performance degradation of flexible substrates (such as polyimide). In contrast, electrochemical 3D printing can directly "write" micron-level silver wires on the surface of PDMS or ultrathin polyimide films at room temperature. By dynamically controlling the electrolyte flow rate and deposition voltage, wire specifications can be achieved that are far lower than those of traditional manufacturing, while maintaining significantly higher precision.

[0003] For example, a five-axis micro-fluid jet metal 3D printing device and method, patent number CN108914177 A, first uses an insulating capillary as the micro-nozzle diameter (100-500 μm), inserts a micron platinum wire in the middle and connects it to the power anode, and sprays the electrolyte onto the cathode substrate surface to achieve local electrodeposition. A constant current DC power supply is used, and the desired three-dimensional metal structure is deposited by controlling the XYZ axes and two rotating motions. However, only one type of electrolyte can be used, greatly reducing its application range. A 3D printing device and method for preparing ordered porous metal electrodes, patent number CN118060544 A, can achieve both synchronous movement of the anode metal rod and the jet electrodeposition nozzle as a whole, and relative movement between the anode metal rod and the jet electrodeposition nozzle to replenish the anode metal rod in real time, ensuring the stability and continuity of the jet electrodeposition process. However, this device is a single-channel deposition device, which has limitations. The jet electrodeposition nozzle device and 3D printer in patent number CN116005215 A can continuously and evenly flow the plating solution to the lower nozzle, which can improve the efficiency of electrodeposition and accelerate the formation of the deposited layer on the workpiece. However, the electrolyte is located in a closed space, and the device needs to be disassembled and refilled with electrolyte every time a print is made, which is very troublesome.

[0004] In summary, the previously mentioned inventions all suffer from single-metal ion deposition, difficulty in electrolyte replenishment, and difficulty in disassembling and replacing the nozzle. However, the multi-channel single-nozzle printing system of this invention can print alloy products and effectively solves the shortcomings of traditional devices, significantly reducing costs compared to traditional multi-printhead solutions. Therefore, a multi-channel single-nozzle electrodeposition jet liquid stream 3D printing structure is designed to improve the range and efficiency of liquid stream additive manufacturing. Summary of the Invention

[0005] This invention addresses the shortcomings of existing electrodeposition jet 3D printer mechanical structures, such as the limitation of using only one type of deposition fluid, difficulty in disassembling and replacing the nozzle, and difficulty in controlling printing precision.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0024] Example 1: As Figures 1-7 As shown, a multi-channel single-nozzle electrodeposition jet liquid beam 3D printing structure includes an X-axis transmission mechanism 1, a Y-axis transmission mechanism 2, a multi-channel printing mechanism 3, an L-shaped support 4, a gate-shaped support 5, a worktable 6, a Z-axis transmission mechanism 7, and a waste liquid treatment device 8. The X-axis transmission mechanism 1 is used for the lateral positioning of the multi-channel printing mechanism 3 in the horizontal plane; The Y-axis transmission mechanism 2 is used to control the lateral movement of the worktable 6, forming an orthogonal planar motion with the X-axis transmission mechanism 1, and together realizing the two-dimensional positioning of the printing platform; The Z-axis transmission mechanism 7 is used to realize the vertical lifting of the worktable 6 and the Y-axis transmission mechanism 2, complete the printing layer thickness control and layer changing action, and together with the X-axis transmission mechanism 1 and the Y-axis transmission mechanism 2, realize the three-dimensional positioning of the printing platform. The multi-channel printing mechanism 3 includes a multi-inlet single-outlet flow channel structure and a flow channel control valve, enabling multiple metal ion liquids to be ejected from a single nozzle; The waste liquid treatment device 8 removes waste liquid from the flow channel of the multi-channel printing mechanism 3 and the worktable by controlling high-speed airflow through valves.

[0025] In operation, different types of solutions are filled into multiple channels of the multi-channel printing mechanism 3. Based on the desired structure and composition of the product to be printed, the control program controls the opening of valves, thus controlling the liquid to enter the printing stage and indirectly meeting the composition requirements. Then, the X-axis drive mechanism 1, Y-axis drive mechanism 2, and Z-axis drive mechanism 7 are controlled via a terminal to manage the printing process, thereby coordinating with the liquid output from the multi-channel printing mechanism 3 to control the structure of the printed product. This indirect and efficient structure solves the problem of single-component products in traditional liquid jet additive manufacturing and can meet the printing needs of products with complex compositions.

[0026] Specifically, such as Figure 3 As shown, the X-axis transmission mechanism 1 includes a first motor 1-1, a first ball screw 1-2, a first guide rail 1-3, a first limiter 1-4, a first base plate 1-5, and a sliding plate 1-6. The first base plate 1-5 is fixed below the portal frame 5. The first drive motor 1-1, the first guide rail 1-3, and the first limiter 1-4 are fixed on the base plate 1-5. One end of the first ball screw 1-2 is connected to the first motor 1-1 through a coupling, and the other end is provided with the first limiter 1-4. The first guide rail 1-3 is provided on both sides of the first ball screw 1-2. The sliding plate 1-6 is installed on the first ball screw 1-2. The flow channel switching mechanism 3 is fixed on the sliding plate 1-6. The two sides of the sliding plate 1-6 are respectively installed in the first guide rail 1-3. Under the drive of the first motor 1-1, the first ball screw 1-2 drives the sliding plate 1-6 to achieve reciprocating motion along the first guide rail 1-3 along the X-axis.

[0027] Specifically, such as Figure 4 As shown, the Y-axis transmission mechanism 2 includes a second motor 2-1, a second ball screw 2-2, a second guide rail 2-3, a second limiter 2-4, and a second base plate 2-5. The second motor 2-1, the second guide rail 2-3, and the second limiter 2-4 are fixed on the second base plate 2-5. One end of the second ball screw 2-2 is connected to the second motor 2-1 through a coupling, and the other end is provided with the second limiter 2-4. The second guide rail 2-3 is provided on both sides of the second ball screw 2-2. The worktable 6 is installed on the second ball screw 2-2 and inside the second guide rail 2-3. Driven by the second motor 2-1, the second ball screw 2-2 drives the worktable 6 to reciprocate along the second guide rail 2-3 to achieve Y-axis reciprocating motion. The Z-axis transmission mechanism 7 drives the second base plate 2-5 to move along the Z-axis direction, thereby realizing the vertical movement of the Y-axis transmission mechanism 2 and the worktable 6.

[0028] Specifically, such as Figure 5As shown, the Z-axis transmission mechanism 7 includes a third motor 7-1, a trapezoidal bracket 7-2, a third guide rail 7-3, a third ball screw 7-4, a third limiter 7-5, a synchronous belt 7-6, a pulley 7-7, and a side plate 7-8. The side plate 7-8 is vertically fixed on the L-shaped bracket 4. The third motor 7-1, the third guide rail 7-3, and the third limiter 7-5 are fixed on the side plate 7-8. One end of the third ball screw 7-4 is connected to the synchronous belt 7-6 and the pulley 7-7. The third motor 7-1 is connected, and the other end is equipped with a third limiter 7-5. The third ball screw 7-4 is equipped with third guide rails 7-3 on both sides. The trapezoidal bracket 7-2 is installed on the third ball screw 7-4 and inside the third guide rails 7-3. The second base plate 2-5 in the Y-axis transmission mechanism 2 is fixed on the trapezoidal bracket 7-2. Under the drive of the third motor 7-1, the third ball screw 7-4 drives the trapezoidal bracket 7-2 to achieve reciprocating motion along the third guide rails 7-3 along the Z-axis.

[0029] Specifically, such as Figure 6 As shown, the multi-channel printing mechanism 3 includes multiple feed channels 3-3 and a multi-channel single nozzle 3-2. The multiple feed channels 3-3 are connected to the multi-channel single nozzle 3-2, and each feed channel 3-3 is also equipped with a valve 3-1. The feed channels 3-3 are fixed to the substrate by welding, while the multi-channel single nozzle 3-2 is fixed to the bottom of the substrate by screws, which facilitates disassembly and replacement with nozzles of other types and shapes.

[0030] The independent feed channel 3-3 design enables real-time switching of multiple materials during the printing process, effectively avoiding premature mixing and chemical reaction interference between materials and ensuring the stability of the electrochemical performance of the materials. On the other hand, the integrated multi-channel single printhead 3-2 design significantly optimizes the spatial layout of the printhead, greatly reducing the overall size and weight of the printhead. This not only improves the flexibility and response speed of the printing motion, but also reduces the inertial influence of moving parts, making the printing of complex trajectories smoother.

[0031] The multi-channel printing mechanism 3 features an optimized flow channel diameter design, ensuring smooth and efficient electrolyte delivery, reducing fluid resistance, and effectively controlling flow rate for precise flow control during printing. Valve 3-1 employs a precision-machined sealing structure to effectively prevent electrolyte leakage and ensure a safe and reliable printing environment. Simultaneously, the smooth fit between the valve core and the inner wall of the flow channel reduces fluid erosion and wear on the structure, enhancing the device's durability. Furthermore, its normally closed structure ensures the flow channel remains closed during power outages, preventing electrolyte leakage while enabling millisecond-level precise matching of flow channel opening and closing to meet the requirements of electrochemical 3D printing.

[0032] Specifically, such as Figure 7As shown, the waste liquid treatment device 8 includes a main pipe 8-2, multiple feed pipes 8-3, and a waste liquid treatment pipe 8-4. The main pipe 8-2 is connected to the waste liquid treatment pipe 8-4 and the multiple feed pipes 8-3 in sequence. The multiple feed pipes 8-3 are respectively connected to multiple feed channels 3-3 in the multi-channel printing mechanism 3. The solenoid valve 8-1 is located between the waste liquid treatment pipe 8-4 and the feed pipes 8-3 to control whether the high-speed airflow enters the feed pipe to achieve waste liquid removal.

[0033] The waste liquid treatment device 8 uses a two-position, normally closed solenoid valve 8-1, made of high-strength, high-pressure-resistant alloy material. Its internal flow channel features a streamlined, optimized design, capable of withstanding the continuous impact of high-speed airflow. While ensuring air circuit sealing, it effectively reduces airflow resistance, ensuring a stable and rapid output of high-speed airflow. The waste liquid treatment pipeline 8-4 surrounds the multi-channel single nozzle 3-2, with its outlet pointing towards the worktable 6, efficiently flushing and removing waste liquid from the nozzle flow channel and the surface of the worktable 6. The normally closed solenoid valve has instantaneous response characteristics; it automatically closes the air circuit to prevent gas leakage when power is off, and opens the air circuit in a very short time after power is applied, precisely controlling the timing and duration of the high-speed airflow injection to avoid unnecessary airflow loss.

[0034] This embodiment uses a four-channel configuration as an example, but the device is not limited to four channels, such as... Figure 7 As shown, there is a main pipe 8-2 connecting two feed pipes 8-3 from left to right and a waste liquid treatment pipe 8-4. The feed pipes 8-3 branch off into two pipes (perpendicular to...). Figure 6 (Flat surface) is used for liquid inlet and, together with Figure 6 The feed channel 3-3 is connected by four pipes. During feeding, simply open the required solenoid valve and close the others. If four different electrolytes enter the four pipes respectively, the feeding process is as follows: the first solenoid valve is opened and the others are closed—the first electrolyte is introduced into the main pipe 8-2 from the right and flows into the feed channel 3-3 along the feed pipe 8-3—after the first electrolyte is introduced, the second solenoid valve is opened and the first solenoid valve is closed—the second electrolyte is introduced… until all four electrolytes are introduced—printing begins and is completed—the waste liquid treatment device solenoid valve 8-1 is opened and all other solenoid valves are closed—the waste liquid in the waste liquid treatment pipe is introduced into the main pipe 8-2 from the right and blown out through the waste liquid treatment pipe 8-4 for unified harmless treatment.

[0035] As can be seen, the entire process involves n feed valves, controlled by n valves, plus one airflow valve for waste liquid treatment, for a total of n+1 flow channels and valves. Taking a four-channel system as an example, the five solenoid valves are numbered: solenoid valve V1, solenoid valve V2, solenoid valve V3, solenoid valve V4, and solenoid valve V5. Solenoid valves V1, V2, V3, and V4 control the flow channels, while solenoid valve V5 controls the high-speed airflow. The workflow is: solenoid valve V1 operates - solenoid valve V2 operates - solenoid valve V3 operates - solenoid valve V4 operates - solenoid valve V5 operates - solenoid valve V1 operates, meaning that after all printing processes are completed, a high-speed airflow is introduced to remove the waste liquid. This control can perform deposition of up to four metals, i.e., additive manufacturing of alloys formed from four metals. The PLC control system can control the processing time to the millisecond level.

[0036] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
