Description

Technical Field

[0001] The utility model relates to the technical field of radar, in particular to an anti-cracking device for radar absorbing honeycomb impregnation. Background Technique

[0002] Radar absorbing honeycomb impregnation is an important process applied to radar stealth technology. Radar absorbing materials can effectively absorb and reduce the reflection of electromagnetic waves (such as radar waves), reducing the probability of being detected by radar. Due to its lightweight and high-strength characteristics, the honeycomb structure is widely used in fields such as aerospace. After combining with absorbing materials, its performance can be further improved. In practical applications, the radar absorbing honeycomb structure needs to penetrate the absorbing coating into every void of the honeycomb material through the impregnation process to improve the absorbing effect and structural strength.

[0003] In the manufacturing process of the radar absorbing honeycomb structure, impregnation is a crucial step. The honeycomb material is usually in a semi-cured state. When impregnating the absorbing coating, it is necessary to ensure that the coating can be evenly distributed and fully penetrate into the internal and external structures of the honeycomb. This step has extremely high requirements for the process because if the impregnation is uneven or excessive, problems such as cracking of the honeycomb material are likely to occur. In order to prevent the honeycomb structure from cracking during the impregnation process, it is usually necessary to adopt a process of repeatedly impregnating the absorbing coating and drying. Through multiple impregnations and drying, the density of the absorbing coating can be gradually increased, avoiding damage to the honeycomb structure caused by excessive penetration of the coating at one time.

[0004] However, the existing impregnation and drying processes have many inconveniences in actual operation. After each impregnation operation, the honeycomb material usually needs to be transferred from the impregnation equipment to an independent drying equipment for drying treatment. This repeated transfer operation not only increases the complexity and time cost of the process flow, but also increases the risk of damage to the material during the transfer process, affecting production efficiency and quality consistency. Therefore, how to simplify the impregnation and drying operations, reduce the transfer links, and ensure the integrity of the material and the uniform penetration of the coating has become an urgent problem to be solved. In view of this, we propose an anti-cracking device for radar absorbing honeycomb impregnation. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-cracking device for radar absorbing honeycomb impregnation to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A crack prevention device for radar absorbing honeycomb impregnation, including an impregnation tank body, which is used to hold absorbing paint and accommodate radar absorbing honeycomb materials during the impregnation process, so that the materials can be evenly impregnated in the paint. On the top of both sides of the impregnation tank body, there are support vertical plates, and the tops of the two support vertical plates are jointly connected with a fixed top plate, which is connected and fixed to the top of the support vertical plates, providing a stable platform for installing a lifting component and a heating lamp board;

[0008] On the top of the fixed top plate, there is a lifting component. The lifting component includes two first fixed vertical plates arranged symmetrically left and right. The bottom of the first fixed vertical plate is fixedly connected to the top of the fixed top plate. Between the two first fixed vertical plates, there is a first rotating rod rotatably connected. On the outside of one of the first fixed vertical plates, there is a first servo motor for driving the first rotating rod to rotate. The first servo motor works with an external power supply. On the outer wall of the first rotating rod and near the positions of the left and right ends, there are winding rollers. On both winding rollers, there are traction ropes wound. The bottom ends of the two traction ropes both penetrate through the top of the fixed top plate and are jointly connected with a hollow storage box, which is used to place radar absorbing honeycomb materials. By driving the first rotating rod to rotate through the first servo motor, the first rotating rod drives the two winding rollers to rotate, so that the two winding rollers respectively wind or unwind the two traction ropes. When winding, the hollow storage box is pulled up by the two traction ropes. When unwinding, the two traction ropes release the hollow storage box to move downward, so that the hollow storage box enters the impregnation tank body;

[0009] On the bottom of the fixed top plate, there is a first heating lamp board, which is used to preliminarily dry the honeycomb materials in the hollow storage box, ensure the uniform drying of the paint, and prevent the honeycomb materials from cracking.

[0010] Preferably, on the bottom of the right side of the impregnation tank body, there is a drain pipe, and a control valve is arranged on the drain pipe, which is used to discharge the remaining absorbing paint after impregnation and control the drainage flow through the control valve.

[0011] Preferably, on the top of the left and right sides of the hollow storage box and near the front and rear ends, there are first fixed bumps, and on the top of the four first fixed bumps, there are positioning rods, and the top ends of the positioning rods penetrate through the bottom of the fixed top plate, ensuring the stability of the hollow storage box during the lifting and lowering processes, and preventing tilting or deviation.

[0012] Preferably, in the middle of the top of the left and right sides of the hollow storage box, there are second fixed bumps. A circular hole is opened on the top of the second fixed bump. The bottom end of the traction rope passes through the circular hole and is fixedly connected with an anti - detachment block, which is fixed at the bottom end of the traction rope. By passing through the circular hole on the hollow storage box, it plays a role in preventing the traction rope from accidentally detaching from the hollow storage box, ensuring the safety of the lifting process.

[0013] Preferably, an auxiliary drying component is provided at the rear side of the bottom of the fixed top plate. The auxiliary drying component includes two second fixed vertical plates arranged symmetrically left and right. A second rotating rod is rotatably connected between the two second fixed vertical plates. A second servo motor for driving the second rotating rod to rotate is provided outside one of the second fixed vertical plates. The second servo motor operates with an external power supply, and the second rotating rod is driven to rotate forward and backward by the second servo motor.

[0014] Preferably, a plurality of L-shaped connecting rods arranged at equal intervals left and right are provided on the outer wall of the second rotating rod. The front ends of the plurality of L-shaped connecting rods are commonly connected to a second heating lamp panel. The second rotating rod drives the plurality of L-shaped connecting rods to rotate, so that the plurality of L-shaped connecting rods drive the second heating lamp panel to rotate. When the hollow storage box is lifted to the highest position and no solution drips, the second heating lamp panel rotates to directly below the hollow storage box for further heating the honeycomb material to ensure the complete drying of the coating and prevent the material from cracking due to local non-drying.

[0015] Preferably, a controller is provided outside one of the support vertical plates. The first heating lamp panel, the second heating lamp panel, the first servo motor and the second servo motor are electrically connected to the controller through wires respectively.

[0018] 2. For the anti-cracking device for radar-absorbing honeycomb impregnation, through multiple precisely controlled lifting and drying operations, it ensures that the radar-absorbing coating uniformly penetrates into each gap of the honeycomb material, and uses the heating lamp panel to gradually dry the material, avoiding the problem of honeycomb material cracking caused by excessive penetration or uneven distribution of the coating.

[0019] 3. For the anti-cracking device for radar-absorbing honeycomb impregnation, the design of the hollow storage box in cooperation with the use of the positioning rod and the fixed convex block ensures the stability of the honeycomb material during the impregnation and drying processes, preventing the material from tilting or shaking during the lifting process, and further improving the uniformity and safety of the coating impregnation.

[0032] A lifting assembly 4 is provided on the top of the fixed top plate 3. The lifting assembly 4 includes two first fixed vertical plates 40 arranged symmetrically left and right. The bottom of the first fixed vertical plate 40 is fixedly connected to the top of the fixed top plate 3. A first rotating rod 41 is rotatably connected between the two first fixed vertical plates 40. A first servo motor 42 for driving the first rotating rod 41 to rotate is provided outside one of the first fixed vertical plates 40. The first servo motor 42 operates with an external power supply. Winding rollers 43 are provided at positions near the left and right ends on the outer wall of the first rotating rod 41. Traction ropes 44 are wound around the two winding rollers 43. The bottom ends of the two traction ropes 44 both penetrate through the top of the fixed top plate 3 and are jointly connected to a hollow storage box 5. The hollow storage box 5 is used to place the radar-absorbing honeycomb material. By driving the first rotating rod 41 to rotate with the first servo motor 42, the first rotating rod 41 drives the two winding rollers 43 to rotate, so that the two winding rollers 43 respectively wind or unwind the two traction ropes 44. When winding, the hollow storage box 5 is pulled upward by the two traction ropes 44. When unwinding, the two traction ropes 44 release the hollow storage box 5 to move downward, so that the hollow storage box 5 enters the impregnation tank body 1;

[0033] A first heating lamp panel 6 is provided at the bottom of the fixed top plate 3, which is used to initially dry the honeycomb material in the hollow storage box 5, ensure the uniform drying of the paint, and prevent the honeycomb material from cracking.

[0036] Furthermore, second fixing bumps 52 are provided in the middle of the top of the left and right sides of the hollow storage box 5. Circular holes 520 are provided at the tops of the second fixing bumps 52. The bottom end of the traction rope 44 passes through the circular hole 520 and is fixedly connected with an anti-disengagement block 440, which is fixed to the bottom end of the traction rope 44. By passing through the circular hole 520 on the hollow storage box 5, it plays a role in preventing the traction rope 44 from accidentally disengaging from the hollow storage box 5 and ensures the safety of the lifting process.

[0037] Furthermore, an auxiliary drying assembly 7 is provided at the rear side of the bottom of the fixed top plate 3. The auxiliary drying assembly 7 includes two second fixed vertical plates 70 arranged symmetrically left and right. A second rotating rod 71 is rotatably connected between the two second fixed vertical plates 70. A second servo motor 72 for driving the second rotating rod 71 to rotate is provided outside one of the second fixed vertical plates 70. The second servo motor 72 operates with an external power supply, and the second rotating rod 71 is driven to rotate forward and backward by the second servo motor 72.

[0038] Furthermore, a plurality of L-shaped connecting rods 73 arranged equidistantly left and right are provided on the outer wall of the second rotating rod 71. The front ends of the plurality of L-shaped connecting rods 73 are commonly connected to a second heating lamp panel 74.

When the hollow storage box 5 is lifted to the highest position and there is no solution dripping, the second heating lamp panel 74 rotates to directly below the hollow storage box 5 for further heating the honeycomb material to ensure the complete drying of the coating and prevent the material from cracking due to incomplete drying in some parts.

[0039] Furthermore, a controller 9 is provided outside one of the support vertical plates 2. The first heating lamp panel 6, the second heating lamp panel 74, the first servo motor 42, and the second servo motor 72 are electrically connected to the controller 9 through wires respectively. Users can operate the first heating lamp panel 6, the lifting assembly 4, and the auxiliary drying assembly 7 through the controller 9 to achieve the automatic control of the entire device.

[0040] When the anti-cracking device for radar-absorbing honeycomb impregnation in this embodiment is in use, inject the radar-absorbing coating into the impregnation tank body 1, and ensure that the coating liquid level is appropriate, so that it is suitable to impregnate all the structures of the honeycomb material. Place the radar-absorbing honeycomb material to be impregnated in the hollow storage box 5, and ensure that the material is placed securely to avoid tilting or shifting during impregnation and lifting. Start the controller 9, and operate the first servo motor 42 of the lifting assembly 4 through the controller 9 to drive the winding roller 43 to rotate, thereby releasing the traction rope 44, and control the slow descent of the hollow storage box 5 into the impregnation tank body 1 to ensure that the honeycomb material is completely immersed in the absorbing coating. During the impregnation process, keep the honeycomb material staying in the coating for a period of time so that the absorbing coating can fully penetrate into every gap of the honeycomb structure. After the impregnation is completed, use the controller 9 to operate the first servo motor 42 again to tighten the traction rope 44 and lift the hollow storage box 5 together with the honeycomb material above the impregnation tank body 1. During the lifting process, the first heating lamp panel 6 starts to preliminarily dry the honeycomb material in the hollow storage box 5 to ensure uniform drying of the coating and prevent the cracking of the honeycomb structure caused by excessive residual coating. When the hollow storage box 5 is lifted to the highest point and there is no excess solution dripping, start the auxiliary drying assembly 7. The second servo motor 72 drives the second rotating rod 71 to rotate, and moves the second heating lamp panel 74 below the hollow storage box 5. The second heating lamp panel 74 performs further all-round drying on the honeycomb material to ensure that all the coatings are completely dried and avoid cracking or poor performance caused by local non-drying. After the impregnation and drying processes are completed, wait for the honeycomb material to cool to a safe temperature, and then take out the processed honeycomb material.
