Description

Technical Field

[0001] This invention relates to the field of airborne shortwave antenna technology, and in particular to a metal surface coating device for airborne shortwave antennas. Background Technology

[0002] Shortwave communication is one of the most important means of medium- and long-distance communication, and shortwave equipment is also an indispensable piece of equipment for airborne communication. Due to the improved requirements and performance indicators of aircraft under the new circumstances, not only is good communication performance of shortwave equipment required, but also higher requirements are placed on the reliability of shortwave equipment. When airborne shortwave antennas are installed, their surfaces need to be plated. Ordinary plating cannot meet the requirements of airborne shortwave antennas in actual use environments. Therefore, electrolyte plating is required to achieve high-quality metal plating.

[0003] Chinese patent discloses a metal material surface plating device (authorization announcement number CN110424047B), including a body. The body contains an anode reaction chamber with four plating metal plates installed inside. A cathode reaction chamber is located on the right side of the anode reaction chamber, and a drain trough connected to the outside is provided on the right side. A solenoid valve is installed in the drain trough. A clamping block is located in the cathode reaction chamber, and a clamping device is located within the clamping block. The clamping device clamps the metal to be plated. During the plating process, the stirring device circulates the electrolyte from the anode reaction chamber to the cathode reaction chamber, increasing the uniformity of electrolyte concentration and improving the quality and deposition rate of the plating layer. Simultaneously, the oxygen generated in the anode reaction chamber can be directly discharged to the outside, and the hydrogen generated in the cathode reaction chamber can be recovered, improving resource utilization and making the device environmentally friendly and efficient.

[0004] Although the aforementioned device uses cathode and anodic reaction chambers to plate metal materials, and is equipped with a stirring and clamping device to uniformly stir the electrolyte and use the clamping device to hold and position the material before immersing it in the electrolyte for plating, when plating airborne shortwave antennas, the shape of the airborne shortwave antenna differs from other metal materials. The left-right clamping method is not conducive to the stability of the airborne shortwave antenna, making it easy for it to detach from the clamping device when immersed in the electrolyte. Furthermore, the clamping device is immersed vertically into the electrolytic cell, which easily generates air bubbles, causing the airborne shortwave antenna to detach from the clamping device. Poor wall plating results, coupled with the static, vertical entry into the electrolyte, increased the thickness of the ion diffusion layer and reduced the deposition rate. This necessitated secondary plating at the clamping contact points, increasing process costs. Furthermore, the electrolyte did not readily compensate for pH levels during plating, resulting in an unsuitable acid-base balance. Repeated plating caused changes in the electrolyte's pH, affecting electrode stability, reducing electrolytic reaction efficiency, clogging electrode surfaces, and inhibiting reaction rates. Consequently, the plating quality on the airborne shortwave antenna surface was poor, failing to protect the antenna or extend its lifespan. Summary of the Invention

[0005] Therefore, it is necessary to provide an airborne shortwave antenna metal surface coating device to address the problem that the existing airborne shortwave antenna metal surface coating device is not conducive to acid-base compensation of the electrolyte.

A flipping frame is rotatably installed at the lower end of the bridge. A flipping shaft is connected to the left end of the flipping frame, and a servo motor is fixedly connected to the end of the flipping shaft. A rotating shaft is connected to the right end of the flipping frame. A sliding frame is fixedly provided on the surface of the flipping frame, and a movable seat is slidably installed inside the sliding frame. A clamping plate is fixedly connected to the upper surface of the movable seat, and an airborne shortwave antenna body is placed on the inner side of the clamping plate.

[0007] A lifting screw is rotatably installed on the left side of the electrolytic reaction cell, and a DC rectifier is installed above the lifting screw. A movable frame is slidably installed on the surface of the lifting screw, and an acid and alkali liquid tank is installed on the surface of the movable frame. A connecting pipe is connected to the bottom of the acid and alkali liquid tank, and a metering pump is installed at the output end of the connecting pipe. A dropper head is connected to the output end of the metering pump.

[0008] In one embodiment of the present invention, the left and right sides of the flipping frame are fixedly connected to the flipping shaft and the rotating shaft respectively, and the two sides of the flipping frame are connected to the bridge frame through the flipping shaft and the rotating shaft respectively to form a rotating structure.

[0009] In one embodiment of the present invention, an umbrella wheel is rotatably mounted in the middle of the surface of the flipping frame, and a drive gear is fixedly connected to the center line of the umbrella wheel. A meshing gear is engaged on one side of the drive gear, and a rotating shaft is fixedly connected to the center line of the meshing gear.

[0010] In one embodiment of the present invention, the end of the rotating shaft away from the parasol wheel is threadedly connected to the movable seat, and the parasol wheel achieves joint transmission with the rotating shaft through the meshing structure between the drive gear and the meshing gear.

[0011] In one embodiment of the present invention, the parasol wheels are distributed in four sets in a cross shape about the symmetrical center line of the flipping frame, and a through-shaft motor is installed in the middle of one set of rotating shafts.

[0012] In one embodiment of the present invention, the movable seat forms a sliding structure between the slide rail frame and the flipping frame, and the movable seat and the rotating shaft form a threaded connection structure.

[0013] In one embodiment of the present invention, an electrode mounting frame is installed inside the electrolytic reaction cell, and an anode plate is installed on the inner wall of the electrode mounting frame.

[0014] In one embodiment of the present invention, a gear ring is rotatably mounted inside the electrode mounting bracket, and a stirring rod is mounted on the inner center line of the gear ring. A second gear ring is meshed above the gear ring, and an anti-corrosion motor is mounted on the inner center line of the second gear ring.

[0015] In one embodiment of the present invention, the lower end of the rotating rod is rotatably connected to the upper end of the suspending rod, and an annular stabilizing frame is installed on the outer side of the lower end of the suspending rod.

[0016] The aforementioned airborne shortwave antenna metal surface coating device includes a mounting frame installed above an electrolytic reaction cell. A hanger is mounted on the mounting frame, which is connected to a cable tray via rotating rods and lifting rods. A rotating shaft and a flipping shaft on the cable tray form a rotating structure with the flipping frame. A servo motor drives the flipping shafts to rotate, thereby flipping the frame. Clamping plates are installed on the flipping frame to hold the airborne shortwave antenna body. Four sets of clamping plates are arranged around the base of the airborne shortwave antenna body. The airborne shortwave antenna body is clamped simultaneously by four sets of clamping plates, which improves the stability of the clamping. At the same time, the flipping frame allows the airborne shortwave antenna body clamped and positioned on the flipping frame to enter the electrolytic reaction cell in a dynamic flipping manner. The flipping allows all surfaces of the airborne shortwave antenna body to dynamically contact the electrolyte, reducing the thickness of the ion diffusion layer, increasing the deposition rate, and improving the coating density. In addition, the clamping plates are firmly positioned from all sides, eliminating the need for clamping fixtures. This ensures that the surface of the airborne shortwave antenna body is unobstructed, reducing the number of secondary processing and re-plating, and reducing process costs.

[0017] A movable frame is installed on one side of the electrolytic reaction cell. The height of the movable frame is adjusted using a lifting screw. An acid / alkali tank is mounted on the movable frame, and a pH detection probe is installed at the lower end of the suspension rod. The pH detection probe is used to detect the acid / alkali value of the electrolyte. The acid / alkali tank is connected to a metering pump via a connecting pipe, enabling precise fluid metering. The acid / alkali tank contains diluted acid and alkali solutions. Based on the detected acid / alkali value in the electrolyte, compensation and adjustment are performed. The acid solution acts as an acid regulator to lower the pH, and the alkali solution acts as an alkali regulator to raise the pH, thereby achieving acid-base balance and compensation in the electrolyte, improving electrode stability, increasing electrolytic reaction efficiency, avoiding inhibition of the reaction rate, improving the coating quality of the airborne shortwave antenna surface, and achieving automatic pH compensation during electrolysis.

[0033] The following combination Figure 1 - Figure 7 This invention describes a metal surface coating device for an airborne shortwave antenna.

[0034] The system includes an electrolytic reaction cell 1, a mounting frame 2 fixedly installed above the electrolytic reaction cell 1, a hanger 3 fixedly installed on the top of the mounting frame 2, a drive motor 17 mounted on the surface of the hanger 3, a rotating rod 19 fixedly connected to the output shaft of the drive motor 17, a suspension rod 20 rotatably connected to the lower end of the rotating rod 19, a filter 18 mounted above the drive motor 17, a pH detection probe 21 mounted on the lower end of the suspension rod 20, a base 22 fixedly installed at the bottom of the hanger 3, and a drive motor 23 fixedly mounted on the surface of the base 22. The output shaft of component 3 is fixedly connected to a rotating plate 24. A connecting frame 25 is rotatably connected to the lower end of the rotating plate 24, and a connecting seat 26 is rotatably mounted on the lower end of the connecting frame 25. A bridge frame 27 is fixedly mounted on the bottom of the connecting seat 26, and a tilting frame 28 is rotatably mounted on the lower end of the bridge frame 27. A tilting shaft 29 is connected to the left end of the tilting frame 28, and a servo motor 30 is fixedly connected to the end of the tilting shaft 29. A rotating shaft 32 is connected to the right end of the tilting frame 28. A sliding groove frame 36 is fixedly provided on the surface of the tilting frame 28, and a movable seat 35 is slidably mounted inside the sliding groove frame 36. A clamping plate 37 is fixedly connected to the upper surface of the moving base 35. An airborne shortwave antenna body 31 is mounted on the inner side of the clamping plate 37. The left and right sides of the flip frame 28 are fixedly connected to the flipping shaft 29 and the rotating shaft 32, respectively. The two sides of the flip frame 28 are connected to the bridge frame 27 via the flipping shaft 29 and the rotating shaft 32, respectively, forming a rotating structure. A parachute wheel 33 is rotatably mounted in the middle of the surface of the flip frame 28. A drive gear 38 is fixedly connected to the center line of the parachute wheel 33. A meshing gear 39 is engaged on one side of the drive gear 38, and the center line of the meshing gear 39 is fixedly connected to the center line of the drive gear 38. The rotating shaft 34 is fixedly connected. The end of the rotating shaft 34 away from the parachute wheel 33 is threadedly connected to the movable seat 35. The parachute wheel 33 achieves joint transmission with the rotating shaft 34 through the meshing structure between the drive gear 38 and the meshing gear 39. The parachute wheel 33 is distributed in four sets in a cross shape about the symmetrical center line of the flipping frame 28. A through-shaft motor 41 is installed in the middle of one set of rotating shaft 34. The movable seat 35 forms a sliding structure with the flipping frame 28 through the slide frame 36. The movable seat 35 and the rotating shaft 34 form a threaded connection structure.

[0035] Specifically, the through-shaft motor 41 drives a set of rotating shafts 34 to rotate. The rotation of the rotating shafts 34 causes the parasol wheels 33 to rotate. The four sets of parasol wheels 33 mesh with each other, thus simultaneously driving the rotation of all four sets of parasol wheels 33. The rotation of the parasol wheels 33 drives the drive gear 38 to rotate. The drive gear 38 and the meshing gear 39 are meshed. The drive gear 38 drives the meshing gear 39 to rotate. The meshing gear 39 is connected to the rotating shafts 34. The rotating shafts 34 rotate with the meshing gears 39. The rotation of the rotating shafts 34 is related to the movement of the seat 35. The threaded connection structure between the movable seat 35 and the sliding structure between the sliding seat 35 and the slide frame 36 limits the axial movement of the movable seat 35, allowing the rotating shaft 34 to smoothly convert the rotation of the movable seat 35 into linear movement. This causes the movable seat 35 to move along the slide frame 36, thereby moving the clamping plates 37. The four sets of clamping plates 37 move simultaneously, positioning and clamping the airborne shortwave antenna body 31. The drive motor 23 on the base 22 drives the rotating plate 24 to rotate. The lower end of the rotating plate 24 is rotatably connected to the connecting frame 25, thereby moving the connecting frame 25. The lower end of the connecting frame 25 is connected to the bridge frame 27 via the connecting seat 26, allowing the bridge frame 27 to be adjusted in height. A flip frame 28 is rotatably mounted on the lower end of the bridge frame 27. The flip frame 28 is rotatably connected to both ends of the bridge frame 27 via a flip shaft 29 and a rotation shaft 32. The servo motor 30 drives the flip shaft 29 to rotate, which, in conjunction with the rotation shaft 32 at the other end, flips the flip frame 28. This flipping of the flip frame 28 allows the airborne shortwave antenna body 31, which is clamped and positioned on the flip frame 28, to enter the electrolytic capacitor in a dynamic flipping motion. In reaction tank 1, the flipping process dynamically contacts each surface of the airborne shortwave antenna body 31 with the electrolyte, reducing the thickness of the ion diffusion layer, increasing the deposition rate, and improving the coating density. The AC power is converted into stable DC power by the DC rectifier 5 to provide the electric field driving force required for electroplating. The anode plate 12 serves as the metal source for the coating. After being energized, it oxidizes and dissolves to replenish the metal ions in the electrolyte. The airborne shortwave antenna body 31 serves as the substrate to be plated and acts as the cathode. A reduction reaction occurs on the surface to deposit the metal coating. Metal plating is achieved through the synergistic effect of the anode plate 12, the DC rectifier 5, and the cathode.

[0036] A lifting screw 4 is rotatably installed on the left side of the electrolytic reaction cell 1, and a DC rectifier 5 is installed above the lifting screw 4. A movable frame 6 is slidably installed on the surface of the lifting screw 4. An acid and alkali liquid tank 7 is installed on the surface of the movable frame 6, and a connecting pipe 9 is connected to the bottom of the acid and alkali liquid tank 7. A metering pump 8 is installed at the output end of the connecting pipe 9, and a dropper head 10 is connected to the output end of the metering pump 8. An electrode mounting frame 11 is installed inside the electrolytic reaction cell 1, and an anode plate 12 is installed on the inner wall of the electrode mounting frame 11. A gear ring is rotatably installed inside the electrode mounting frame 11, and a stirring rod 14 is installed on the inner center line of the gear ring. A gear ring 25 is meshed above the gear ring, and a corrosion-resistant motor 16 is installed on the inner center line of the gear ring 25. The lower end of the rotating rod 19 is rotatably connected to the upper end of the lifting rod 20, and an annular stabilizer 40 is installed on the outer side of the lower end of the lifting rod 20.

[0037] Specifically, three sets of drive motors 17 are installed on the mounting bracket 3. The housing of drive motor 17 is made of aluminum alloy material to isolate magnetic fields, and a filter 18 is installed to avoid signal interference. To prevent the motor from being affected by the electrolytic reaction cell 1, the electrodes are vacuum-coated and protected with multiple layers of coating. At the same time, the motor structure is optimized for sealing. The motor interface uses double O-ring fluororubber seals, and the shaft seal uses a ceramic graphite mechanical seal to prevent electroplating solution from seeping in along the shaft gap. Drive motor 17 drives the rotating rod 19 to rotate. The rotating rod 19 is rotatably connected to the lifting rod 20, thereby lifting the lifting rod 20. A pH detection probe 21 is installed at the lower end of the lifting rod 20. By moving the lifting rod 20 up and down, the pH detection probe 21 can detect the pH value of the electrolyte in the electrolytic reaction cell 1. Since the pH value of the electrolyte changes when the surface of the airborne shortwave body is coated, the change in pH value will affect the electrodes. Stability issues lead to decreased electrolytic reaction efficiency. Therefore, the pH value of the electrolyte is measured. After determining the acidity or alkalinity, the moving frame 6 is moved up and down using the lifting screw 4, allowing the acid / alkalinity tanks 7 on the moving frame 6 to approach the electrolytic reaction tank 1. Two sets of acid / alkalinity tanks 7 are provided, each containing diluted acidic liquid hydrochloric acid (HCl) and alkaline liquid sodium hydroxide (NaOH). The liquid in each tank is precisely controlled by the metering pump 8, and the liquid is slowly dripped in using the dropper head 10 to adjust the pH value of the electrolyte until it meets the plating requirements. First, the pH is measured using the pH detection probe 21. The probe detects the difference in hydrogen ion concentration in the electrolyte through a glass electrode and a reference electrode, generating a potential signal proportional to the pH value. This potential signal is converted into a standard electrical signal by a transmitter, and then used as the control target based on the preset value set in the PID control system. Next, a deviation analysis of the pH is performed. If the acidity is too high, the measured pH... <Set a lower limit to trigger the alkali addition command; otherwise, the alkalinity is too high (measured pH).> Set an upper limit to trigger the acid addition command. The output of metering pump 8 is dynamically adjusted according to the pH deviation value and rate of change. When the pH exceeds the limit, metering pump 8 is started and stops after the target value is reached. In this way, automatic acid-base compensation is achieved in the electrolytic reaction tank 1 to avoid quality differences before and after plating. After the acid or alkali is added to the electrolytic reaction tank 1, the anti-corrosion motor 16 drives the gear ring 2 15 to rotate. The gear ring 2 15 and gear ring 1 13 are meshed. Gear ring 1 13 is rotated between the central shaft and the inner wall of the electrolytic reaction tank 1. The anti-corrosion motor 16 is installed on the crossbeam structure in the middle of the upper part of the electrolytic reaction tank 1. At the same time, the gear ring 2 15 is equipped with a stirring rod 14, which drives gear ring 1 13 to rotate, thereby stirring the liquid in the electrolytic reaction tank 1 with the stirring plate, so that the acid or alkali can be fully mixed with the electrolyte and the pH of the electrolyte is balanced.

[0038] In terms of working principle, when using this invention, firstly, the body of the airborne shortwave antenna needs to be placed inside the clamping plate 37. Then, the clamping plate 37 securely holds the airborne shortwave antenna body. During this clamping process, the through-axis motor 41 starts, driving one set of rotating shafts 34 to rotate continuously. As the rotating shafts 34 rotate, the parachute wheels 33 also rotate. The four sets of parachute wheels 33 mesh with each other, thus synchronously driving all four sets of parachute wheels 33 to rotate together. The rotation of the parachute wheels 33 further drives the drive gear 38 to rotate. The drive gear 38 and the meshing gear 39 employ a meshing structure, allowing the drive gear 38 to smoothly drive the meshing gear 39 to rotate together. The meshing gear 39 and the rotating shaft 34 are interconnected, so the rotating shaft 34 will also rotate with the rotation of the meshing gear 39. The rotation of the rotating shaft 34 cooperates with the threaded connection structure between the moving seat 35 and the sliding structure between the moving seat 35 and the slide frame 36, which also plays an auxiliary role, together limiting the axial movement of the moving seat 35 and preventing the moving seat 35 from moving axially. In this way, the rotating shaft 34 can smoothly convert the rotational action of the moving seat 35 into linear movement, so that the moving seat 35 moves along the slide frame 36. As the moving seat 35 moves, the clamping plate 37 will also move accordingly, thereby realizing the positioning and clamping of the airborne shortwave antenna body 31.

[0039] A drive motor 23 is installed on the base 22, driving the rotating plate 24 to rotate. A connecting frame 25 is rotatably connected to the lower end of the rotating plate 24, so the connecting frame 25 also moves up and down with the rotation of the rotating plate 24. The lower end of the connecting frame 25 is connected to the bridge frame 27 via a connecting seat 26, so the bridge frame 27 also adjusts its height as the connecting frame 25 moves up and down. A tilting frame 28 is rotatably installed at the lower end of the bridge frame 27. The tilting frame 28 is rotatably connected to both ends of the bridge frame 27 via a tilting shaft 29 and a rotating shaft 32, respectively. The servo motor 30 drives the tilting shaft 29 to rotate, cooperating with the rotating shaft 32 at the other end to tilt the tilting frame 28. Through the tilting action of the tilting frame 28, the bridge frame 28 rotates. The airborne shortwave antenna body 31, held and positioned on the flipping frame 28, can enter the electrolytic reaction cell 1 in a dynamic flipping motion. This flipping action allows each surface of the airborne shortwave antenna body 31 to dynamically contact the electrolyte, thereby reducing the thickness of the ion diffusion layer, increasing the deposition rate, and ultimately improving the density of the coating. To provide the electric field driving force required for electroplating, a DC rectifier 5 converts alternating current into stable direct current. The anode plate 12, acting as the metal source for the coating, oxidizes and dissolves after being energized, replenishing the metal ions in the electrolyte. The airborne shortwave antenna body 31, serving as the substrate to be plated and acting as the cathode, undergoes a reduction reaction on its surface, depositing a metal coating. This process is achieved through the anode plate 12, the DC rectifier 5, and the cathode. The synergistic effect of the two mechanisms enables the metal plating process. A gear ring is rotatably mounted inside the electrode mounting bracket 11, and a stirring rod 14 is mounted on the center line of the gear ring. A second gear ring 15 is meshed above the gear ring, and a corrosion-resistant motor 16 is mounted on the center line of the second gear ring 15. When acid or alkali is added to the electrolytic reaction tank 1, the corrosion-resistant motor 16 drives the second gear ring 15 to rotate. The second gear ring 15 and the first gear ring 13 are meshed. The first gear ring 13 is rotatably mounted between itself and the inner wall of the electrolytic reaction tank 1 via a central shaft. Simultaneously, the stirring rod 14 is mounted on the second gear ring 15, driving the first gear ring 13 to rotate, thereby moving the stirring plate towards the electrolytic reaction tank. The liquid in cell 1 is stirred to ensure that the acid or alkali solution is fully mixed with the electrolyte, balancing the pH value of the electrolyte. In addition, by moving the lifting rod 20 up and down, the pH detection probe 21 detects the pH value of the electrolyte in the electrolysis reaction cell 1. After detecting the pH value, the lifting screw 4 moves the moving frame 6 up and down, so that the acid and alkali solution tanks 7 on the moving frame 6 can be close to the electrolysis reaction cell 1. There are two sets of acid and alkali solution tanks 7, each containing diluted acidic liquid hydrochloric acid and alkaline liquid sodium hydroxide. The metering pump 8 precisely controls the liquid in the corresponding tank, and the liquid is slowly dripped in through the dropper head 10 to adjust the pH value of the electrolyte.

[0040] It should be noted that the DC rectifier 5, anode plate 12, drive motor 17, drive motor 23, servo motor 30, pH detection probe 21, metering pump 8, through-shaft motor 41 and filter 18 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
