Description

Technical Field

[0001] This utility model relates to the field of electrochemical polishing technology, and in particular to a high-temperature superconducting high-frequency electrochemical polishing device. Background Technology

[0002] Currently, the surface roughness requirement for Hastelloy substrates in mass-produced superconducting stabilization processes is 1-2 nm (5*5 square micrometers scanning area using an atomic force microscope). Due to limitations in rolling mill precision, roll finish, and the cleanliness of the rolling environment, the surface roughness of commercially available high-specification metal substrates is approximately 50 nanometers, typically requiring electrochemical polishing. In existing electrochemical polishing devices, post-polishing cleaning, defect detection, and marking of Hastelloy substrates are often separate processes, requiring the transfer of the substrate between independent workstations, which can easily lead to secondary contamination or positional deviations. Furthermore, the spacing between the detection and cleaning components is difficult to adjust quickly for Hastelloy substrates of varying thicknesses, resulting in poor adaptability. Therefore, we propose a high-frequency electrochemical polishing device for high-temperature superconducting applications to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing electrochemical polishing devices, where the cleaning, inspection, and marking of Hastelloy substrates are separate processes that require multiple transfers, which can easily lead to secondary contamination or positional deviations. Furthermore, the component spacing is difficult to adjust quickly to accommodate Hastelloy substrates of different thicknesses, resulting in poor adaptability. Therefore, this invention proposes a high-temperature superconducting high-frequency electrochemical polishing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature superconducting high-frequency electrochemical polishing device includes an electrolytic cell, with an air-expanding unwinding coil and an air-expanding rewinding coil respectively arranged on both sides of the electrolytic cell, and a detection box fixedly connected between the electrolytic cell and the air-expanding rewinding coil; The detection box has an inclined notch and is connected to the electrolytic cell. A cleaning component, a detection component, and a marking component are sequentially arranged in the notch. The cleaning component includes vertically symmetrical air knives, the detection component includes vertically symmetrical linear CCD camera arrays, the marking component includes vertically symmetrical inkjet components, and the inkjet components include mounting blocks. The air knife, linear CCD camera group and mounting block located below are fixed to the bottom of the recess by fixing bracket I, and the air knife, linear CCD camera group and mounting block located above are slidably connected to the inner wall of the recess by fixing bracket II. The fixed frame II is connected to the adjustment component, which drives the fixed frame II to rise and fall to adjust the distance between the upper and lower components.

[0005] In one possible design, the inkjet assembly further includes a slider that is slidably disposed within a groove in the mounting block, and a miniature inkjet valve is fixed to the slider; a threaded rod I passes through the slider and is connected to the output end of motor I.

[0006] In one possible design, the adjustment assembly includes sliding rods symmetrically fixed to the top of the mounting frame II, the sliding rods passing through the top of the detection box; and an electric telescopic rod fixed to the top of the detection box, the output end of which is connected to the mounting frame II.

[0007] In one possible design, two sets of guide rollers are arranged within the notch, each set including symmetrical guide rollers I; the cleaning component, the detection component, and the marking component are located between the two sets of guide rollers.

[0008] In one possible design, the electrolytic cell is equipped with a limiting component, including two sets of movable frames that are slidably connected to the inner wall of the electrolytic cell, with the pressure roller rotatably connected to the movable frames, and the two movable frames linked together by a connecting rod.

[0009] In one possible design, the connecting rod is fixedly connected to the threaded rod II, which passes through the fixed plate and meshes with the threaded hole of the driven gear; the driving gear meshes with the driven gear, and the output end of the motor II is connected to the driving gear.

[0010] In one possible design, guide rollers II arranged vertically are provided at the inlet of the electrolytic cell; a magnetic powder brake controls the tension of the air-expanding and unwinding coil, and a motor III drives the air-expanding and rewinding coil to wind up.

[0011] In this application, firstly, the Hastelloy base strip is installed on the air-expanding unwinding coil. The magnetic powder brake applies constant tension during the unwinding process to prevent the Hastelloy base strip from loosening or stretching. The Hastelloy base strip is horizontally introduced into the electrolytic cell via guide rollers II arranged vertically. The pressure rollers of the limiting components inside the electrolytic cell are linked by connecting rods. Motor II drives the active gear to mesh with the driven gear, causing the threaded rod II to push the pressure rollers to apply adjustable downward pressure, constraining the Hastelloy base strip to move stably along a preset path in the electrolyte. After electrochemical polishing is completed, the Hastelloy base strip enters the testing box through an inclined notch. Guide roller I supports the Hastelloy base strip to maintain the tilt angle. The upper and lower symmetrical air knives of the notch cleaning component spray low-pressure airflow at a ° angle to peel off the residual electrolyte on the surface of the Hastelloy substrate. The inclined notch structure causes the waste liquid to flow back to the electrolytic cell under the action of gravity. The cleaned Hastelloy substrate enters the detection area. The upper and lower linear CCD camera groups scan both sides of the Hastelloy substrate simultaneously, identify the defect coordinates and transmit them to the control system. When a defect is detected, the motor I of the marking component drives the threaded rod I to rotate, which drives the slider and the micro inkjet valve to move laterally to the defect position, spray ultraviolet curing ink and instantly cure to form a marking point. The Hastelloy base strip is finally exited from the inspection box via guide rollers, and the air-expanding winding tube driven by motor III completes the winding. When polishing and inspecting Hastelloy base strips of various thicknesses, the electric telescopic rod of the adjustment component pushes the fixed frame II up and down along the slide bar to adjust the distance between the upper air knife, camera group and inkjet valve and the lower air knife, camera group and inkjet valve, ensuring stable operation of each link.

[0012] Beneficial effects: The high-temperature superconducting high-frequency electrochemical polishing device of this utility model integrates cleaning components, detection components and marking components in the detection box, and is arranged sequentially along the travel direction of the Hastelloy substrate. It can continuously complete surface electrolyte cleaning, upper and lower surface defect detection and defect marking after the Hastelloy substrate leaves the electrolytic cell, reduce the number of Hastelloy substrate transfers, avoid secondary pollution, shorten the processing flow and improve production efficiency. In this utility model, the high-temperature superconducting high-frequency electrochemical polishing device can drive the fixed frame II and the air knife, linear CCD camera group and inkjet assembly on it to move up and down through the adjustment component, thereby quickly adjusting the spacing between the upper and lower components to adapt to Hastelloy base tapes of different thicknesses and to meet the continuous production needs of Hastelloy base tapes of different thicknesses. It is easy to operate and has high adjustment accuracy. In this invention, the high-temperature superconducting high-frequency electrochemical polishing device is connected to a magnetic powder brake via an air-expanding unwinding kun and a motor III via an air-expanding rewinding kun. The magnetic powder brake can stably control the unwinding tension, and the motor III drives the rewinding. Combined with the limiting component in the electrolytic cell, the Hastelloy substrate is effectively prevented from wrinkling, shifting, or stretching deformation during polishing and transmission, ensuring polishing uniformity and the accuracy of subsequent testing and marking.

[0013] In this invention, the integrated cleaning, inspection, and marking components in the inspection box enable continuous electrolyte cleaning, defect detection, and marking, reducing Hastelloy substrate transfer, avoiding secondary contamination, and improving production efficiency. The adjustable components allow for rapid adjustment of the spacing between the upper and lower components to accommodate Hastelloy substrates of different thicknesses, enhancing adaptability and providing convenient and highly accurate operation. The magnetic powder brake stabilizes the unwinding tension, and the limiting components prevent wrinkles and shifts in the Hastelloy substrate, ensuring the accuracy of polishing and subsequent processing.

The gas expansion and rewinding coils 3 are rotatably connected to one side of the detection box 4, and the gas expansion and unwinding coils 2 are rotatably connected to the side of the electrolytic cell 1 away from the detection box 4. A notch 401 is provided on one side of the detection box 4. The notch 401 is set at an inclined angle and communicates with the electrolytic cell 1.

The fixing frame II is equipped with an adjustment component for adjusting the height of the fixing frame II. The inspection box 4 integrates the cleaning component 5, the inspection component 7, and the marking component 9, which are arranged sequentially along the travel direction of the Hastelloy substrate. It can continuously complete the surface electrolyte cleaning, upper and lower surface defect detection, and defect marking after the Hastelloy substrate leaves the electrolytic cell 1, reducing the number of Hastelloy substrate transfers, avoiding secondary contamination, shortening the processing flow, and improving production efficiency.

[0018] The inkjet assembly includes a miniature inkjet valve 13, which is fixedly mounted on a slider 12.

By pushing the mounting frame II up and down along the slide rods 11 with the electric telescopic rod 10, the distance between the corresponding air knife 6, linear CCD camera group 8, and inkjet assembly located above and the corresponding components below can be adjusted to accommodate Hastelloy basebands of different thicknesses, meeting the continuous production needs of Hastelloy basebands of different thicknesses. The operation is convenient and the adjustment accuracy is high.

A common connecting rod 19 is fixedly connected to the side of the two sliding frames 17 that is close to each other. The pressure roller 18 applies pressure to the Hastelloy base strip, constraining its movement path in the electrolyte and preventing it from shifting.

[0022] A fixed plate 21 is fixedly connected to the top of the electrolytic cell 1. A connecting rod 19 is located below the fixed plate 21 and is fixedly connected to a threaded rod II 20. A driven gear 23 and a driving gear 24 are rotatably connected inside the fixed plate 21. The driven gear 23 and the driving gear 24 are meshed together. The driven gear 23 has a threaded hole that matches the threaded rod II 20. The threaded rod II 20 passes through the fixed plate 21 and is threadedly connected to the threaded hole. A motor II 22 is fixedly installed at the top of the threaded rod II 20. The output end of the motor II 22 extends into the interior of the fixed plate 21, passes through the driving gear 24, and is fixedly connected to the driving gear 24.

The guide rollers II 27 horizontally guide the Hastelloy substrate released from the gas-expanding coil 2 into the electrolytic cell 1, ensuring the Hastelloy substrate remains stable upon entering the electrolytic cell 1.

[0025] A magnetic powder brake 25 and a motor III 26 are fixedly installed on one side of the electrolytic cell 1.
