Description

Technical Field

[0001] This invention belongs to the field of 3D printing technology and electrochemical deposition, specifically relating to a device and method for preparing microanodes by local electrochemical deposition additive manufacturing. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a technology based on the principle of discrete or additive manufacturing, where materials are gradually accumulated to create a finished product. It uses a computer to cut a 3D model of a part into a series of "slices" of a certain thickness. The 3D printing equipment then manufactures each layer of these "slices" from bottom to top, finally stacking them to form a three-dimensional solid part. This manufacturing technology eliminates the need for traditional tools or molds, enabling the creation of complex structures that are difficult or impossible to process using conventional methods. It also effectively simplifies production processes and shortens manufacturing cycles. As a comprehensive application technology, 3D printing integrates cutting-edge technologies from digital modeling, electromechanical control, information technology, materials science, and chemistry, possessing a high level of technological sophistication.

[0003] Localized electrochemical deposition (LECD) is a typical maskless micro-electrochemical additive manufacturing technique that uses an ultrafine inert anode tip to generate a very localized electric field to induce electrodeposition on the cathode, forming micro- and nano-scale 3D features. In LECD, both the anode and cathode are immersed in an electrolyte with a constant small interelectrode gap. The anode moves precisely in space relative to the cathode (or the formed deposit) along a pre-designed path. Simultaneously, metal electrodeposition occurs in a localized region directly below the anode tip, generating a three-dimensional microstructure. Currently, common LECD microanodes are platinum wire disk electrodes encased in capillary glass tubes. Because LECD often forms very small-scale microstructures, it is necessary to encapsulate very small-diameter inert metal wires within the capillary glass tubes. The small diameter and reduced hardness of the inert metal wires present significant challenges to the fabrication of the microanodes. Furthermore, the encapsulated electrodes need to be ground with high flatness requirements using sandpaper and polishing equipment, which also adds to the difficulty of microanode fabrication. Summary of the Invention

[0024] A method for fabricating a microanode fabrication device using localized electrochemical deposition additive manufacturing includes the following steps:

[0025] (1) Model data conversion: Design the 3D printed part structure according to the required electrode structure. The electrode structure consists of two parts: structure one and structure two. Structure one is formed by melting and stacking color one PLA, and structure two is formed by melting and stacking color two PLA. Then, construct the corresponding Catia model, slice the model from the Z direction to make each layer thickness at the micrometer level, and import the graphic information of each layer of the model into the calculation control program.

[0026] (2) Printing of the lower electrode structure: The computer control program controls the heating plate to heat up the printing platform to the required temperature. The stepper motor four on the z-axis moving device rotates to raise the base plate to a suitable height. Under the control of the control program, the nozzle one melts and extrudes the color one PLA filament, and the nozzle two melts and extrudes the color two PLA filament, which is then stacked layer by layer on the printing platform to form the required electrode structure until the electrode structure two is printed and then printing stops.

[0027] (3) Laying the inert metal wire: After the electrode structure 1 is printed, the stepper motor 4 on the Z-axis moving device rotates to lower the base plate to the lowest position. The stepper motor 7 on clamping device 1 rotates to open clamping device 1. The stepper motor 8 on cutting device 1 rotates to open cutting device 1. The stepper motor 11 on clamping device 2 rotates to open clamping device 2. The stepper motor 12 on cutting device 2 rotates to open cutting device 2. The piezoelectric ceramic motor causes the support frame to rotate, moving clamping and cutting device 1 between the roll and the printing platform. When using this device for the first time, the inert metal wire needs to be straightened manually. After straightening, the stepper motor 7 on clamping device 1 rotates to clamp clamping device 1. At this time, the inert metal wire is clamped between the two clamping plates 1. Then, to prevent the inert metal wire from colliding with the printing platform... Interference occurs, and stepper motor 5 on clamping and shearing device 1 rotates, causing clamping and shearing device 1 to rise to a certain height. Stepper motor 9 on clamping and shearing device 2 rotates, causing clamping and shearing device 2 to rise to a certain height. Piezoelectric ceramic motor causes support frame to rotate 180 degrees. At this time, clamping and shearing device 2 rotates to the original position of clamping and shearing device 1. Stepper motor 5 on clamping and shearing device 1 rotates, causing clamping and shearing device 1 to fall to its original height. Stepper motor 9 on clamping and shearing device 2 rotates, causing clamping and shearing device 2 to fall to its original height. Stepper motor 11 on clamping and shearing device 2 rotates to clamp the inert metal wire on the reel. Then, stepper motor 6 on clamping and shearing device 1 and stepper motor 10 on clamping and shearing device 2 make a slight rotation to tension the inert metal wire laid on the lower half of the electrode structure.

[0028] (4) Printing of the upper part of the electrode structure: After laying the inert metal wire, the stepper motor four on the z-axis moving device rotates to raise the base plate to a suitable height. Since the electrode structure two has been printed, only the remaining part of structure one needs to be printed. The control program controls the nozzle one to melt and extrude the color PLA filament, which is then stacked on the printing platform to form the upper part of the electrode.

[0029] (5) Cutting of inert metal wire: After the electrode structure 2 is printed, the inert metal wire is completely encapsulated between structure 1 and structure 2. At this time, the stepper motor 8 on the cutting device 1 rotates to clamp the two blades 1 and the stepper motor 12 on the cutting device 2 rotates to clamp the two blades 2, thereby achieving the cutting of the two ends of the clamped inert metal wire.

[0030] (6) Post-processing of electrodes: The packaged electrodes are scraped off the printing platform with a shovel and cut with a laser cutter according to the required length to obtain electrodes with flush cuts.

[0031] The advantages of this invention are: it automates the fabrication of microanodes by local electrochemical deposition additive manufacturing, improves the efficiency of microanode fabrication, and saves manpower, material resources, and financial resources; it solves the difficulties of encapsulating extremely fine inert metal wires using capillary glass tubes in the traditional method, and can conveniently encapsulate inert metal wires with a diameter of less than 20 micrometers; it uses laser cutting for post-processing of the electrode, avoiding the difficulty of grinding a smooth electrode surface; and the electrode shape can be designed by computer without shape limitations.

[0082] A method for fabricating a microanode fabrication device using localized electrochemical deposition additive manufacturing includes the following steps:

[0083] (1) Model data conversion: Design the 3D printed part structure according to the required electrode structure. The electrode structure consists of two parts: structure one and structure two. Structure one is formed by melting and stacking color one PLA, and structure two is formed by melting and stacking color two PLA. Then, construct the corresponding Catia model, slice the model from the Z direction to make each layer thickness at the micrometer level, and import the graphic information of each layer of the model into the calculation control program.

[0084] (2) Printing of the lower electrode structure: The computer control program controls the heating plate 501 to heat up the printing platform 502 to the required temperature. The stepper motor 404 on the z-axis moving device rotates to raise the base plate 401 to a suitable height. Under the control of the control program, the nozzle 1 301 melts and extrudes the color PLA filament, and the nozzle 2 302 melts and extrudes the color PLA filament, which is then stacked layer by layer on the printing platform 502 to form the required electrode structure until the electrode structure 2 is printed and then printing stops.

[0085] (3) Laying inert metal wire: After the electrode structure is printed, stepper motor 404 on the Z-axis moving device rotates to lower the base plate 401 to its lowest position. Stepper motor 7 604 604 605 on clamping device 1 rotates to open clamping device 1 604 604. Stepper motor 8 604 608 605 on shearing device 1 rotates to open shearing device 1 604 608.

[0086] (4) Printing of the upper part of the electrode structure: After laying the inert metal wire, the stepper motor 404 on the z-axis moving device rotates to raise the base plate 401 to a suitable height. Since the second electrode structure has been printed, only the remaining part of the first structure needs to be printed. The control program controls the nozzle 301 to melt and extrude the color PLA filament, which is then deposited on the printing platform 502 to form the upper part of the electrode.

[0087] (5) Cutting of inert metal wire: After electrode structure two is printed, the inert metal wire is completely encapsulated between structure one and structure two. At this time, the stepper motor eight 6040805 on the cutting device one rotates to clamp the two blades one 6040801 and the stepper motor twelve 6050805 on the cutting device two rotates to clamp the two blades two 6050801, thereby achieving the cutting of both ends of the clamped inert metal wire.

The model is sliced ​​and layered in the Z direction to make each layer the thickness of micrometers. The graphic information of each layer of the model is then imported into the calculation control program.

The stepper motor 404 on the Z-axis moving device rotates, raising the base plate 401 to a suitable height.

[0093] (4) Printing of the upper part of the electrode structure: After laying the inert metal wire, the stepper motor 404 on the z-axis moving device rotates to raise the base plate 401 to a suitable height.
