Description

Technical Field

[0001] The invention relates to the technical field of airborne shortwave antennas, in particular to a metal surface plating device for airborne shortwave antennas. Background Art

[0002] Shortwave communication is one of the most important means of communication for medium and long distance communication, and shortwave equipment is also indispensable equipment for airborne communication. Due to the improvement of aircraft demand and performance indicators under the new situation, not only is the communication effect of shortwave equipment required to be good, but also the reliability of shortwave equipment is put forward higher requirements. When the airborne shortwave antenna is put into installation, the surface of the airborne shortwave antenna needs to be plated. Ordinary plating cannot meet the actual use environment of the airborne shortwave antenna. Therefore, electrolyte plating is required to achieve high-quality metal plating.

[0003] A Chinese patent discloses a metal material surface plating device (authorization announcement number CN110424047B), which includes a body, an anode reaction chamber is provided in the body, four plated metal plates are installed in the anode reaction chamber, a cathode reaction chamber is provided on the right side of the anode reaction chamber, and a drainage trough is provided on the right side communicating with the outside world, an electromagnetic valve is installed in the drainage trough, a clamping block is provided in the cathode reaction chamber, a clamping device is provided in the clamping block, and the metal to be plated is clamped on the clamping device. During the plating process of the present invention, a stirring device causes the electrolyte to circulate from the anode reaction chamber to the cathode reaction chamber, which can increase the concentration uniformity of the electrolyte, improve the quality of the coating and the precipitation rate. At the same time, the oxygen generated in the anode reaction chamber can be directly discharged to the outside world, and the hydrogen generated in the cathode reaction chamber can be recovered, thereby improving resource utilization, being environmentally friendly and efficient.

[0004] Although the above device uses the cathode reaction chamber and the anode reaction chamber to plate the metal material through the positive and negative pole reaction chambers, and is equipped with a stirring device and a clamping device to stir the electrolyte evenly, and uses the clamping device to clamp and position the material, and then puts the material into the electrolyte for plating, when plating the airborne shortwave antenna, the shape of the airborne shortwave antenna is different from that of other metal materials, and the left and right clamping has poor stability for the airborne shortwave antenna, so that the airborne shortwave antenna is immersed in the electrolyte and easily falls off from the clamping device, and the clamping device is immersed in the electrolytic cell straight up and down, and such an immersion path is prone to generate bubbles, which makes the appearance of the airborne shortwave antenna The wall plating effect is not good, and the static straight-up and straight-down entry into the electrolyte increases the thickness of the ion diffusion layer and reduces the deposition rate, so that the clamped contact points need secondary processing and re-plating, which increases the process cost. In addition, during the plating process, the electrolyte is not conducive to the pH value compensation of the electrolyte in the electrolyte cell, resulting in poor acidity and alkalinity in the electrolyte. When the material is repeatedly plated, the pH value in the electrolyte will change. The change in pH value will affect the stability of the electrode, resulting in a decrease in the efficiency of the electrolytic reaction, blocking the electrode surface, and inhibiting the reaction rate, resulting in poor plating quality on the surface of the airborne shortwave antenna, resulting in the plating failing to protect and extend the life of the airborne shortwave antenna.

The output shaft of the turning plate 24 is fixedly connected to the turning plate 24, the lower end of the turning plate 24 is rotatably connected to the connecting frame 25, and the lower end of the connecting frame 25 is rotatably installed with a connecting seat 26, the bottom of the connecting seat 26 is fixedly installed with a bridge frame 27, the lower end of the bridge frame 27 is rotatably installed with a flip frame 28, the left end of the flip frame 28 is connected to a flip shaft 29, and the end of the flip shaft 29 is fixedly connected to a servo motor 30, the right end of the flip frame 28 is connected to a rotating shaft 32, the surface of the flip frame 28 is fixedly provided with a slide frame 36, and the interior of the slide frame 36 is slidably installed with a moving seat 35, The upper surface of the movable seat 35 is fixedly connected with a clamping plate 37, and the inner side of the clamping plate 37 is provided with an airborne shortwave antenna body 31. The left and right sides of the flip frame 28 are respectively fixedly connected with the flip shaft 29 and the rotating shaft 32, and the two sides of the flip frame 28 are respectively connected with the bridge 27 through the flip shaft 29 and the rotating shaft 32 to form a rotating structure. The middle of the surface of the flip frame 28 is rotatably installed with an umbrella wheel 33, and the center line of the umbrella wheel 33 is fixedly connected with a driving gear 38. A meshing gear 39 is provided on one side of the driving gear 38, and the center line of the meshing gear 39 is fixed. A fixed connecting rotating shaft 34 is provided. The end of the rotating shaft 34 away from the umbrella wheel 33 is threadedly connected to the movable seat 35. The umbrella wheel 33 realizes a joint transmission with the rotating shaft 34 through the meshing structure between the driving gear 38 and the meshing gear 39. The umbrella wheel 33 has four groups distributed in a cross shape about the symmetrical center line of the turnover frame 28, and a through-axis motor 41 is installed in the middle of one group of rotating shafts 34. The movable seat 35 forms a sliding structure with the turnover frame 28 through the slide frame 36, and a threaded connection structure is formed between the movable seat 35 and the rotating shaft 34. Specifically, the through-axis motor 41 drives a set of rotating shafts 34 to rotate, and the rotation of the rotating shafts 34 drives the umbrella wheels 33 to rotate. The four sets of umbrella wheels 33 are meshed with each other, thereby driving the four sets of umbrella wheels 33 to rotate at the same time. The rotation of the umbrella wheels 33 will drive the driving gear 38 to rotate. The driving gear 38 and the meshing gear 39 are meshed. The driving gear 38 drives the meshing gear 39 to rotate. The meshing gear 39 is connected to the rotating shaft 34. The rotating shaft 34 rotates with the meshing gear 39. The rotation of the rotating shaft 34 is connected to the moving seat 35. The threaded connection structure between them cooperates with the sliding structure between the moving seat 35 and the slide frame 36 to limit the axial position of the moving seat 35, so that the rotating shaft 34 can smoothly convert the rotation of the moving seat 35 into linear movement, so that the moving seat 35 moves along the slide frame 36, and then moves with the clamping plate 37. The four groups of clamping plates 37 move at the same time to position and clamp the airborne shortwave antenna body 31. The driving 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 bringing the connecting frame 25 The lower end of the connecting frame 25 is connected to the bridge frame 27 through the connecting seat 26, and the bridge frame 27 is lifted and lowered. The lower end of the bridge frame 27 is rotatably installed with a flip frame 28. The flip frame 28 is rotatably connected to the two ends of the bridge frame 27 through a flip shaft 29 and a rotating shaft 32. The servo motor 30 drives the flip shaft 29 to rotate, and cooperates with the rotating shaft 32 at the other end to flip the flip frame 28. The flip of the flip frame 28 enables the airborne shortwave antenna body 31 clamped and positioned on the flip frame 28 to enter the electrolytic circuit in a flipping dynamic form. In the reaction pool 1, the airborne shortwave antenna body 31 is flipped so that each surface is in dynamic contact with the electrolyte, reducing the thickness of the ion diffusion layer, increasing the deposition rate, and improving the density of the coating. The DC rectifier 5 is used to convert the alternating current into stable direct current to provide the electric field driving force required for electroplating. The anode plate 12 serves as the plating metal source. After power is turned on, it is oxidized and dissolved to replenish the metal ions in the electrolyte. The airborne shortwave antenna body 31 is the substrate to be plated and serves as the cathode. A reduction reaction occurs on the surface to deposit a metal coating. Metal plating is achieved through the synergistic action of the anode plate 12, the DC rectifier 5, and the cathode.

[0026] A lifting screw rod 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 rod 4. A mobile frame 6 is slidably installed on the surface of the lifting screw rod 4, and an acid and alkali liquid tank 7 is installed on the surface of the mobile frame 6. The bottom of the acid and alkali liquid tank 7 is connected to a connecting pipe 9, and 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 2 15 is meshed and installed above the gear ring, and an anti-corrosion motor 16 is installed on the inner center line of the gear ring 2 15. The lower end of the rotating rod 19 is rotatably connected to the upper end of the suspension rod 20, and an annular stabilizing frame 40 is installed on the outer side of the lower end of the suspension rod 20; Specifically, three groups of drive motors 17 are installed on the bracket 3. The shell of the drive motor 17 is made of aluminum alloy material that isolates the magnetic field, and is equipped with a filter 18 to avoid signal interference. In order to prevent the motor from being affected by the electrolytic reaction cell 1, the electrode is vacuum coated and sealed, and multi-layer coating protection is adopted. At the same time, the motor structure seal is optimized, and a double O-type fluororubber sealing ring is used at the motor interface. The shaft seal uses a ceramic graphite mechanical seal to prevent the electroplating solution from penetrating along the shaft gap. The drive motor 17 drives the rotating rod 19 to rotate. The rotating rod 19 is rotatably connected to the suspension rod 20, thereby realizing the lifting of the suspension rod 20. A pH detection probe 21 is installed at the lower end of the suspension rod 20. Through the up and down movement of the suspension rod 20, the pH detection probe 21 detects the pH value of the electrolyte in the electrolytic reaction cell 1. Since the pH value of the electrolyte will change when the electrolyte is plated on the surface of the airborne shortwave body, the change in pH value will affect the electrode. Stability leads to a decrease in the efficiency of the electrolytic reaction. Therefore, the pH value of the electrolyte is tested. After the pH value is detected, the lifting screw 4 is used to move the mobile frame 6 up and down so that the acid and alkali liquid tank 7 on the mobile frame 6 can be close to the electrolytic reaction cell 1. There are two groups of acid and alkali liquid tanks 7, both of which are filled with diluted acidic liquid hydrochloric acid HCl and alkaline liquid sodium hydroxide NaOH. The metering pump 8 accurately controls the amount of liquid in the corresponding tank, and the dropper head 10 slowly drips the liquid to adjust the pH value of the electrolyte until the pH value of the electrolyte meets the requirements of plating. First, the pH detection probe 21 is used to detect the pH value. The probe detects the hydrogen ion concentration difference of the electrolyte through the glass electrode and the reference electrode, and generates a potential signal proportional to the pH value. The potential signal is converted into a standard electrical signal by the transmitter, and then used as the control target according to the preset value set in the PID control system. Then, the pH value is analyzed for deviation. If the acidity is too high, the measured pH value < Setting a lower limit triggers the alkali solution addition instruction. Conversely, if the alkalinity is too high, the measured pH value > Setting an upper limit triggers the acid solution addition instruction. The output of the metering pump 8 is dynamically adjusted according to the pH deviation value and the rate of change. The metering pump 8 is started when the pH exceeds the limit and stopped when it reaches the target value. In this way, automatic acid-base compensation is achieved in the electrolytic reaction cell 1 to avoid quality differences before and after the plating process. After the acid or alkali solution is added to the electrolytic reaction cell 1, the anti-corrosion motor 16 is used to drive the gear ring 2 15 to rotate. The gear ring 2 15 and the gear ring 1 13 are meshed. The gear ring 13 is rotatably installed between the central shaft and the inner wall of the electrolytic reaction cell 1. The anti-corrosion motor 16 is installed on the beam structure in the middle of the upper part of the electrolytic reaction cell 1. At the same time, the gear ring 2 15 is equipped with a stirring rod 14 to drive the gear ring 1 13 to rotate, and then the stirring plate is used to stir the liquid in the electrolytic reaction cell 1, so that the acid or alkali solution can be fully integrated with the electrolyte and the pH value of the electrolyte is balanced.

[0027] Working principle: When using the present invention, first, the body of the airborne shortwave antenna needs to be placed on the inner side of the clamping plate 37. Then, the body of the airborne shortwave antenna is firmly clamped by the clamping plate 37. During the clamping process, the through-axis motor 41 is started to drive one group of rotating shafts 34 to perform continuous rotation. As the rotating shafts 34 rotate, the umbrella wheels 33 will also rotate. The four groups of umbrella wheels 33 are meshed with each other, so that the four groups of umbrella wheels 33 can be synchronously driven to rotate together. The rotation of the umbrella wheels 33 will further drive the driving gear 38 to rotate. The driving gear 38 and the meshing gear 39 adopt a meshing structure, so that the driving gear 38 can smoothly drive the meshing gear 39 to rotate together. The meshing gear 39 and the rotating shaft 34 are connected to each other, so the rotating shaft 34 will also rotate with the rotation of the meshing gear 39, and the rotation of the rotating shaft 34 cooperates with the threaded connection structure between the movable seat 35. At the same time, the sliding structure between the movable seat 35 and the slide frame 36 also plays an auxiliary role, and together they limit the axial position of the movable seat 35 to prevent the movable seat 35 from axial movement. In this way, the rotating shaft 34 can smoothly convert the rotation action of the movable seat 35 into linear movement, so that the movable seat 35 moves along the slide frame 36. As the movable seat 35 moves, the clamping plate 37 will also move accordingly, thereby realizing the positioning and clamping of the airborne shortwave antenna body 31. A driving motor 23 is installed on the base 22 to drive the rotating plate 24 to rotate. The lower end of the rotating plate 24 is rotatably connected to the connecting frame 25, so the connecting frame 25 will also move 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 through the connecting seat 26, so that the bridge frame 27 will also be raised and lowered as the connecting frame 25 moves up and down. The lower end of the bridge frame 27 is rotatably installed with a flip frame 28. The flip frame 28 is rotatably connected to the two ends of the bridge frame 27 through a flip shaft 29 and a rotating shaft 32. The servo motor 30 drives the flip shaft 29 to rotate, and cooperates with the rotating shaft 32 at the other end to flip the flip frame 28. Through the flipping action of the flip frame 28, The airborne shortwave antenna body 31 clamped and positioned on the flip frame 28 can enter the electrolytic reaction cell 1 in a flipping dynamic form. The flipping action enables 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 further improving the density of the coating. In order to provide the electric field driving force required for electroplating, the DC rectifier 5 is used to convert the AC power into a stable DC power. The anode plate 12 serves as the coating metal source and will oxidize and dissolve after power is applied, thereby replenishing the metal ions in the electrolyte. The airborne shortwave antenna body 31 serves as the substrate to be plated and as the cathode. A reduction reaction occurs on the surface to deposit a metal coating. Through the anode plate 12, the DC rectifier 5 and the cathode The synergistic effect realizes the process of metal plating. The internal rotation of the electrode mounting frame 11 is installed with a gear ring, the internal center line of the gear ring is installed with a stirring rod 14, and the upper part of the gear ring is meshed with a gear ring 2 15. The internal center line of the gear ring 2 15 is installed with an anti-corrosion motor 16. When acid or alkali solution is added to the electrolytic reaction cell 1, the anti-corrosion motor 16 is used to drive the gear ring 2 15 to rotate. There is a meshing structure between the gear ring 2 15 and the gear ring 1 13. The gear ring 13 is rotatably installed between the central shaft and the inner wall of the electrolytic reaction cell 1. At the same time, the gear ring 2 15 is equipped with a stirring rod 14 to drive the gear ring 1 13 to rotate, and then the stirring plate is brought to the electrolytic reaction cell. 1 is stirred evenly, so as to ensure that the acid or alkali solution can be fully integrated with the electrolyte and the pH value of the electrolyte is balanced. In addition, by moving the lifting rod 20 up and down, the pH detection probe 21 is used to detect the pH value of the electrolyte in the electrolytic reaction cell 1. After detecting the pH value, the lifting screw 4 is used to move the movable frame 6 up and down, so that the acid and alkali liquid tank 7 on the movable frame 6 can be close to the electrolytic reaction cell 1. There are two groups of acid and alkali liquid tanks 7, both of which are filled with diluted acidic liquid hydrochloric acid and alkaline liquid sodium hydroxide. The metering pump 8 is used to accurately control the amount of liquid in the corresponding tank, and the liquid is slowly dripped into the dropper head 10 to adjust the pH value of the electrolyte.

[0028] It should be noted that the DC rectifier 5, anode plate 12, drive motor 1 17, drive motor 2 23, servo motor 30, pH detection probe 21, metering pump 8, through-axis motor 41 and filter 18 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs and will not be elaborated here.

[0029] The technical features of the above embodiments can be combined arbitrarily.
