Description

Technical Field

[0001] The invention relates to the technical field of wave-absorbing honeycomb preparation devices, and in particular to a wave-absorbing honeycomb impregnation device. Background Art

[0002] Honeycomb material is a material invented based on the principle of bionics. Its structure is similar to that of honeycombs in nature and has a unique hexagonal structure. Honeycomb material can not only evenly withstand the force applied by the outside world, but also has a light weight. It can reduce the weight of the material as much as possible while ensuring sufficient structural strength. Therefore, honeycomb material is an important matrix material.

[0003] When honeycomb materials are used in certain fields (for example, in stealth aircraft), in order to make the honeycomb materials have certain wave-absorbing properties (i.e., be able to absorb electromagnetic waves and achieve stealth function), the honeycomb materials need to be immersed in an impregnating liquid containing a wave-absorbing agent, so that the wave-absorbing agent adheres to the surface of the honeycomb material and penetrates into the interior of the honeycomb material, thereby obtaining a wave-absorbing honeycomb.

[0004] At present, when making a wave-absorbing honeycomb, the entire honeycomb material is generally immersed in an impregnation liquid, so that the wave-absorbing honeycomb as a whole has a wave-absorbing function. However, in some application scenarios, part of the honeycomb material is required to have a wave-absorbing function, while the other part does not.

[0056] First embodiment

[0057] like Figures 1 to 7 As shown, the microwave absorbing honeycomb impregnation device provided in the first embodiment of the present invention treats the honeycomb structure 9 by immersion, so that the impregnation liquid adheres to the honeycomb structure 9. The microwave absorbing honeycomb impregnation device includes:

[0058] A liquid storage tank 1, wherein a liquid storage cavity 10 is provided inside the liquid storage tank 1, and the liquid storage cavity 10 is used to contain an impregnation liquid containing an absorbent (not shown);

[0059] The hook assembly 2 is arranged on the inner wall of the liquid storage chamber 10 (that is, arranged on the inner wall of the liquid storage tank 1). The hook assembly 2 includes a plurality of hooks 20, at least some of which have different heights; the honeycomb structure 9 can be hung on the hooks 20 of different heights to adjust the immersion depth of the honeycomb structure 9 in the impregnation liquid, so that the honeycomb structure 9 can be partially or completely immersed in the impregnation liquid for immersion, thereby achieving the effect of partial immersion or overall immersion.

[0060] Specifically, the wave absorbing agent in the impregnation liquid can generally be iron powder, carbonyl iron powder, carbon powder, alloy powder, etc. When the honeycomb structure 9 is immersed in the impregnation liquid, the wave absorbing agent in the impregnation liquid can be adsorbed on the honeycomb holes 91 ( Figure 2 The middle honeycomb hole 91 is schematically shown as a square, but in reality the honeycomb hole 91 should be a hexagonal structure. The specific structure of the honeycomb hole 91 can be referred to Fig. 20) and immersed in the honeycomb structure 9, so that the honeycomb structure 9 has a wave absorbing function, that is, a wave absorbing honeycomb is obtained. When in use, according to actual product requirements, the honeycomb structure 9 is hung on the hooks 20 at different heights, so that the honeycomb structure 9 has different hanging heights, and then the area and position of the honeycomb structure 9 immersed in the impregnation liquid are adjusted.

[0061] The wave-absorbing honeycomb impregnation device provided in the embodiment of the present invention is provided with a plurality of hooks 20 on the inner wall of the liquid storage chamber 10, and at least some of the hooks 20 have different heights; by hanging the honeycomb structure 9 on the hooks 20 at different heights, the immersion depth of the honeycomb structure 9 in the impregnation liquid is adjusted, and the honeycomb structure 9 can be impregnated as a whole or partially, so that a wave-absorbing honeycomb with wave-absorbing function as a whole or with wave-absorbing function in part can be obtained to meet different product requirements.

[0062] like Figure 3 , Figure 6 and Figure 7 As shown, as an embodiment, the plurality of hooks 20 include a plurality of first hooks 21 and a plurality of second hooks 22, and the plurality of first hooks 21 and the plurality of second hooks 22 are respectively arranged on the inner walls of the opposite sides of the liquid storage chamber 10 (that is, respectively arranged on the inner walls of the opposite sides of the liquid storage tank 1). At least some of the first hooks 21 have different heights, and at least some of the second hooks 22 have different heights. The opposite ends of the honeycomb structure 9 can be respectively hung on the first hook 21 and the second hook 22 to improve the stability of the honeycomb structure 9 and prevent the honeycomb structure 9 from falling during the immersion process.

[0063] When hanging, the opposite ends of the honeycomb structure 9 can be hung on the first hook 21 and the second hook 22 at different heights, and the honeycomb structure 9 is in an inclined state (i.e., Figure 3 The honeycomb structure 9 can be partially immersed in the impregnating liquid (of course, in the inclined state, as long as the honeycomb structure 9 is located below the liquid surface as a whole, the honeycomb structure 9 can also be immersed as a whole); the opposite ends of the honeycomb structure 9 can also be respectively hung on the first hook 21 and the second hook 22 at the same height. At this time, the honeycomb structure 9 is in a lying state, and the honeycomb structure 9 can be immersed as a whole (when the honeycomb structure 9 is in a lying state, it is generally impossible to partially immerse the honeycomb structure 9).

[0064] like Figure 3 , Figure 6 and Figure 7As shown, as an implementation mode, the plurality of first hooks 21 correspond to the plurality of second hooks 22 in a one-to-one manner in the horizontal direction X, and the heights of the corresponding first hooks 21 and second hooks 22 are the same or similar.

[0065] like Figure 3 , Figure 6 and Figure 7 As shown, as an implementation mode, the opening directions of the first hook 21 and the second hook 22 are opposite. In this embodiment, the opening of the first hook 21 faces upward, and the opening of the second hook 22 faces downward, so as to facilitate the hanging and fixing of the honeycomb structure 9. Of course, in other embodiments, the opening directions of the first hook 21 and the second hook 22 can also be the same, for example, both face upward.

[0066] like Figure 3 , Figure 6 and Figure 7 As shown, as an embodiment, a plurality of first hooks 21 are arranged in an array in the horizontal direction X and the vertical direction Y, and a plurality of second hooks 22 are arranged in an array in the horizontal direction X and the vertical direction Y.

[0067] like Figure 3 , Figure 6 and Figure 7 As shown, as an embodiment, the plurality of first hooks 21 are divided into a plurality of first groups 210 (such as Figure 6 As shown, the first hook 21 in the dotted frame is a first group 210), each first group 210 includes a plurality of first hooks 21 (three in the figure), the plurality of first hooks 21 in each first group 210 are arranged at intervals along the horizontal direction X, and the plurality of first groups 210 are arranged at intervals along the vertical direction Y. Specifically, the plurality of first hooks 21 in each first group 210 are arranged at equal intervals along the horizontal direction X, and the plurality of first groups 210 are arranged at equal intervals along the vertical direction Y.

[0068] The plurality of second hooks 22 are divided into a plurality of second groups 220 (eg Figure 7 As shown, the second hook 22 in the dotted frame is a second group 220), each second group 220 includes a plurality of second hooks 22, the plurality of second hooks 22 in each second group 220 are arranged at intervals along the horizontal direction X, and the plurality of second groups 220 are arranged at intervals along the vertical direction Y. Specifically, the plurality of second hooks 22 in each second group 220 are arranged at equal intervals along the horizontal direction X, and the plurality of second groups 220 are arranged at equal intervals along the vertical direction Y.

[0069] One end of the honeycomb structure 9 can be simultaneously connected to a plurality of first hooks 21 in one of the first groups 210, and the other end of the honeycomb structure 9 can be simultaneously connected to a plurality of second hooks 22 in one of the second groups 220, thereby improving the stability of the honeycomb structure 9. At the same time, the opposite ends of the honeycomb structure 9 can be respectively connected to the first group 210 and the second group 220 of different heights, or respectively connected to the first group 210 and the second group 220 of the same height.

[0070] like Figure 3 , Figure 6 and Figure 7 As shown, as an embodiment, a plurality of first groups 210 are arranged in sequence from the bottom of the liquid storage chamber 10 to the top of the liquid storage chamber 10, and a plurality of second groups 220 are arranged in sequence from the bottom of the liquid storage chamber 10 to the top of the liquid storage chamber 10, so that the honeycomb structure 9 can adjust its hanging height according to different liquid levels.

[0071] like Figure 3 and Figure 4 As shown, as an embodiment, the wave-absorbing honeycomb impregnation device further includes a stirring device 43, which is arranged in the liquid storage chamber 10, and is used to stir the impregnation liquid in the liquid storage chamber 10. Specifically, since the wave-absorbing agent in the impregnation liquid will settle after being left still for a period of time, the efficiency of the wave-absorbing agent adhering to the honeycomb structure 9 during the immersion process is reduced; in order to make the wave-absorbing agent evenly dispersed in the impregnation liquid, it is necessary to set a stirring device 43 to stir the impregnation liquid to improve the attachment efficiency. It should be noted that since the liquid level will fluctuate up and down during the stirring process, in order to avoid the impregnation liquid from contacting the parts of the honeycomb structure 9 that do not need to be immersed due to the up and down fluctuation of the liquid level during the stirring process, it is generally necessary to separate the honeycomb structure 9 from the impregnation liquid before stirring (since the hook 20 is used in this embodiment to hang and fix the honeycomb structure 9, it is necessary to manually or other tools to remove the honeycomb structure 9 from the liquid storage tank 1 before stirring), and then stir the impregnation liquid.

[0072] Specifically, in the present embodiment, the stirring device 43 is an impeller stirring device, and there are multiple stirring devices 43 , which are arranged at intervals at the bottom of the liquid storage tank 1 .

[0073] like Figure 1 and Figure 2 As shown, as an embodiment, the wave-absorbing honeycomb impregnation device further includes a dosing device 42, which is located outside the liquid storage tank 1 and is connected to the liquid storage chamber 10. The dosing device 42 is used to add impregnation liquid into the liquid storage chamber 10 to supplement the wave-absorbing agent.

[0074] Specifically, in this embodiment, the dosing device 42 may include a silo (not shown), a dosing pump (not shown), etc., and the silo stores the impregnation liquid; the inlet of the dosing pump is connected to the silo, and the outlet of the dosing pump is connected to the liquid storage chamber 10, and the dosing pump can be used to add the impregnation liquid to the liquid storage chamber 10.

[0075] like Figure 1 , Figure 2 and Figure 8 As shown, as an embodiment, the wave-absorbing honeycomb impregnation device further includes a concentration detection device 41 and a control module 40. The concentration detection device 41 is arranged on the liquid storage tank 1 (specifically, the concentration detection device 41 can be arranged outside the liquid storage tank 1, and the probe of the concentration detection device 41 is located inside the liquid storage tank 1). The concentration detection device 41 is used to detect the content of the wave-absorbing agent in the impregnation liquid in the liquid storage chamber 10. The control module 40 is respectively connected to the concentration detection device 41, the dosing device 42 (specifically, it can be connected to the dosing pump by electrical signals) and the stirring device 43 by electrical signals; the control module 40 is used to control the dosing device 42 to add the impregnation liquid to the liquid storage chamber 10 when the concentration detection device 41 detects that the content of the wave-absorbing agent in the impregnation liquid in the liquid storage chamber 10 is lower than the preset value, and control the stirring device 43 to stir the impregnation liquid in the liquid storage chamber 10 so that the added wave-absorbing agent can be evenly dispersed. The control module 40 can specifically be a PLC controller.

[0076] like Figure 8 As shown, as an embodiment, the absorbing honeycomb impregnation device further includes an alarm device 44, which is used to send out an alarm message. The control module 40 is also electrically connected to the alarm device 44; the control module 40 is used to control the alarm device 44 to send out a corresponding alarm message to remind the staff when the concentration detection device 41 detects that the content of the absorbing agent in the impregnation liquid in the liquid storage chamber 10 is lower than a preset value. The alarm device 44 can be specifically an audible and visual alarm, a display screen, etc.

[0077] like Figure 5 As shown, as an embodiment, the liquid storage tank 1 includes a heating liner 11 and an outer shell 12, the heating liner 11 is arranged in the outer shell 12, the liquid storage cavity 10 is arranged in the heating liner 11, and the hook 20 is arranged on the inner wall of the heating liner 11. The heating liner 11 can heat the immersion liquid in the liquid storage cavity 10 to maintain the immersion liquid at a desired temperature.

[0078] Specifically, in this embodiment, a heating element 13 (specifically, a heating circuit) is provided on the outer wall of the heating liner 11, and the heating element 13 can heat the heating liner 11; of course, the heating liner 11 can also be heated in other ways. The heating liner 11 is made of Teflon material, or a Teflon coating is provided on the inner wall of the heating liner 11 to improve the wear resistance and corrosion resistance of the heating liner 11.

[0079] As an embodiment, the liquid storage tank 1 is further provided with a temperature sensor (not shown), which is used to detect the temperature of the immersion liquid in the liquid storage chamber 10. The control module 40 is also electrically connected to the temperature sensor and the heating element 13; the control module 40 is used to control the heating element 13 to work when the temperature sensor detects that the temperature of the immersion liquid in the liquid storage chamber 10 is lower than a set value, so as to heat the immersion liquid in the liquid storage chamber 10, and stop heating after reaching a preset temperature.

[0080] like Figures 1 to 3 As shown, as an embodiment, the top of the liquid storage tank 1 is provided with an opening (not numbered in the figure), and the honeycomb structure 9 can be taken in and out through the opening, and a top cover 14 is provided at the opening, and the top cover 14 can seal the opening. By providing the top cover 14, not only can foreign matter from outside be prevented from falling into the liquid storage tank 1, but also the evaporation and escape of the impregnation liquid during the heating process can be reduced or prevented.

[0081] Second embodiment

[0082] like Figures 9 to 13 As shown, the wave-absorbing honeycomb impregnation device provided in the second embodiment of the present invention is substantially the same as the first embodiment, and it also treats the honeycomb structure 9 by immersion. The difference is that the immersion depth of the honeycomb structure 9 is adjusted differently.

[0083] Specifically, in this embodiment, the wave-absorbing honeycomb impregnation device includes:

[0084] A liquid storage tank 1, wherein a liquid storage cavity 10 is provided inside the liquid storage tank 1, and the liquid storage cavity 10 is used to contain an impregnation liquid containing an absorbent;

[0085] The height adjustment component 3 is arranged corresponding to the liquid storage chamber 10, and the height adjustment component 3 is used to connect the honeycomb structure 9. The height adjustment component 3 can move up and down to adjust the immersion depth of the honeycomb structure 9 in the impregnation liquid, and can not only immerse the honeycomb structure 9 as a whole, but also partially immerse the honeycomb structure 9, so that an absorbing honeycomb with an overall absorbing function or an absorbing honeycomb with a partial position having an absorbing function can be obtained to meet different product requirements.

[0086] like Figures 10 to 12 As shown, as an embodiment, the height adjustment component 3 includes a plurality of telescopic drive devices 31, the plurality of telescopic drive devices 31 are arranged at intervals, and the plurality of telescopic drive devices 31 are respectively used to connect with different parts of the honeycomb structure 9. The plurality of telescopic drive devices 31 can independently perform up and down telescopic movements to adjust the immersion depth of the honeycomb structure 9 in the impregnation liquid.

[0087] Specifically, since the multiple telescopic drive devices 31 are respectively connected to different parts of the honeycomb structure 9, and the multiple telescopic drive devices 31 can independently perform up and down telescopic movements, by adjusting the telescopic height of each telescopic drive device 31, the height of each part of the honeycomb structure 9 can be adjusted, thereby adjusting the posture and immersion depth of the honeycomb structure 9 to achieve the effect of partial immersion or full immersion. For example, in this embodiment, the number of telescopic drive devices 31 is four, and the four telescopic drive devices 31 are arranged at intervals, and the four telescopic drive devices 31 are respectively connected to the four vertex positions of the honeycomb structure 9; when full immersion is required, the telescopic heights of the four telescopic drive devices 31 can be the same (or different), so that the honeycomb structure 9 is in a flat state and is immersed in the immersion liquid as a whole; when partial immersion is required, the telescopic heights of the two telescopic drive devices 31 on one side are controlled to be lower than the telescopic heights of the two telescopic drive devices 31 on the other side, so that the honeycomb structure 9 is in an inclined state and partially immersed in the immersion liquid. Generally, the number of telescopic drive devices 31 is not less than two or three.

[0088] like Figures 10 to 12 As shown, as an embodiment, the telescopic drive device 31 can be a structure such as a pneumatic cylinder, an electric cylinder, a linear slide rail module, etc. The telescopic drive device 31 is arranged at the bottom of the liquid storage tank 1. The telescopic drive device 31 includes a driving part (not numbered in the figure) and a telescopic rod (not numbered in the figure). The driving part is located below the liquid storage tank 1 and is fixed to the liquid storage tank 1. The telescopic rod extends from bottom to top into the liquid storage chamber 10; the bottom end of the telescopic rod is connected to the driving part, and the top end of the telescopic rod is connected to the honeycomb structure 9. The driving part can drive the telescopic rod to telescope up and down, thereby adjusting the height of the honeycomb structure 9. Of course, in other embodiments, the telescopic drive device 31 can also be arranged above the liquid storage tank 1. In this case, the telescopic drive device 31 can be a hoisting device (that is, the telescopic drive device 31 suspends the honeycomb structure 9).

[0089] like Figures 10 to 12 As shown, as an embodiment, the height adjustment component 3 also includes a telescopic support device 33, and the telescopic support device 33 is arranged corresponding to the middle position of the liquid storage chamber 10, and the telescopic support device 33 can also independently telescope up and down. When the texture of the honeycomb structure 9 is relatively soft, the telescopic support device 33 can be used to support the middle position of the honeycomb structure 9 to avoid the middle of the honeycomb structure 9 from being sunken. Of course, in other embodiments, if the texture of the honeycomb structure 9 is relatively hard and not easy to deform, there is no need to set the telescopic support device 33. The structure of the telescopic support device 33 is the same as or similar to that of the telescopic drive device 31, and will not be repeated here.

[0090] like Figures 9 to 13As shown, as an embodiment, the wave-absorbing honeycomb impregnation device further includes a stirring device 43 . The stirring device 43 is disposed in the liquid storage chamber 10 . The stirring device 43 is used to stir the impregnation liquid in the liquid storage chamber 10 .

[0091] like Figures 9 to 13 As shown, as an embodiment, the wave-absorbing honeycomb impregnation device further includes a dosing device 42, which is located outside the liquid storage tank 1 and is connected to the liquid storage chamber 10. The dosing device 42 is used to add impregnation liquid into the liquid storage chamber 10 to supplement the wave-absorbing agent.

[0092] like Figures 9 to 13 As shown, as an embodiment, the wave-absorbing honeycomb impregnation device further includes a concentration detection device 41 and a control module 40. The concentration detection device 41 is disposed on the liquid storage tank 1, and is used to detect the content of the wave-absorbing agent in the impregnation liquid in the liquid storage chamber 10. The control module 40 is respectively connected to the concentration detection device 41, the dosing device 42 and the stirring device 43 by electrical signals; the control module 40 is used to control the dosing device 42 to add the impregnation liquid to the liquid storage chamber 10 when the concentration detection device 41 detects that the content of the wave-absorbing agent in the impregnation liquid in the liquid storage chamber 10 is lower than a preset value, and control the stirring device 43 to stir the impregnation liquid in the liquid storage chamber 10, so that the added wave-absorbing agent can be evenly dispersed.

[0093] like Figures 9 to 13 As shown, as an embodiment, the control module 40 is also electrically connected to the height adjustment component 3 (specifically, electrically connected to multiple telescopic drive devices 31 respectively); the control module 40 is used to control the height adjustment component 3 to extend upward before the stirring device 43 stirs the impregnation liquid in the liquid storage chamber 10, so that the honeycomb structure 9 moves upward and separates from the impregnation liquid, and then controls the stirring device 43 to stir the impregnation liquid in the liquid storage chamber 10, so as to avoid the liquid level fluctuating up and down during the stirring process and causing the impregnation liquid to contact the parts of the honeycomb structure 9 that do not need to be immersed.

[0094] The other structures and functions (including heating function, alarm function, etc.) of this embodiment are the same as or similar to those of the first embodiment and will not be described in detail here.

[0095] Third embodiment

[0096] like Figures 14 to 16As shown, the wave-absorbing honeycomb impregnation device provided in the third embodiment of the present invention is basically the same as the second embodiment, except that: the height adjustment component 3 also includes a support plate 32 for placing the honeycomb structure 9, and a plurality of telescopic drive devices 31 are respectively connected to different parts of the support plate 32. A plurality of meshes 321 are provided on the support plate 32, and the plurality of meshes 321 correspond to a plurality of honeycomb holes 91 on the honeycomb structure 9. Specifically, the support plate 32 can support the honeycomb structure 9 to prevent the soft honeycomb structure 9 from deforming; at the same time, since a plurality of meshes 321 are provided on the support plate 32, and the meshes 321 on the support plate 32 correspond to the honeycomb holes 91 on the honeycomb structure 9, the impregnation of the impregnation liquid into the honeycomb holes 91 will not be affected. At the same time, compared with the second embodiment, since the support plate 32 is provided to support the honeycomb structure 9 in this embodiment, there is no need to provide a telescopic support device.

[0097] The other structures and functions of this embodiment are the same as or similar to those of the second embodiment and are not described in detail here.

[0098] Fourth embodiment

[0099] like Figures 17 to 22 As shown, the absorbing honeycomb impregnation device provided in the fourth embodiment of the present invention processes the honeycomb structure 9 by spraying first and then soaking, so that the impregnation liquid adheres to the honeycomb structure 9. The absorbing honeycomb impregnation device includes a liquid spraying device 5 and a plugging device 6, and the liquid spraying device 5 is located above the plugging device 6. The plugging device 6 is used to place the honeycomb structure 9 and plug the bottom openings of the multiple honeycomb holes 91 on the honeycomb structure 9. The liquid spraying device 5 includes a plurality of nozzles 51, and the plurality of nozzles 51 respectively correspond to the plurality of honeycomb holes 91 on the honeycomb structure 9, and the plurality of nozzles 51 can independently spray the impregnation liquid containing the absorbing agent into the plurality of honeycomb holes 91 on the honeycomb structure 9 (specifically, the nozzles 51 spray the impregnation liquid into the honeycomb holes 91 through the top openings of the honeycomb holes 91).

[0100] Specifically, the honeycomb structure 9 is provided with a plurality of honeycomb holes 91, and the honeycomb holes 91 are open at both ends, that is, the honeycomb holes 91 have a top opening (not numbered in the figure) and a bottom opening (not numbered in the figure). When in use, the honeycomb structure 9 is first placed / installed on the plugging device 6, and the bottom openings of the honeycomb holes 91 on the honeycomb structure 9 are blocked by the plugging device 6 to prevent the impregnation liquid in the honeycomb holes 91 from flowing out; then, the impregnation liquid is sprayed into the plurality of honeycomb holes 91 on the honeycomb structure 9 through the plurality of nozzles 51 in the liquid spraying device 5. Since the multiple nozzles 51 spray the impregnation liquid independently, the immersion position of the honeycomb structure 9 can be accurately controlled by controlling whether each nozzle 51 sprays the impregnation liquid (and the spraying amount of the nozzle 51 can be controlled) to achieve the effect of partial immersion or overall immersion (for example, when the honeycomb structure 9 needs to be immersed as a whole, all the nozzles 51 are controlled to spray the impregnation liquid so that all the honeycomb holes 91 are sprayed with the impregnation liquid; when the honeycomb structure 9 needs to be partially immersed, some of the nozzles 51 are controlled to spray the impregnation liquid to spray the impregnation liquid into the honeycomb holes 91 at the required position). After the nozzle 51 sprays, since the bottom opening of the honeycomb hole 91 is blocked by the blocking device 6, the impregnation liquid will remain in the honeycomb hole 91 to soak the honeycomb structure 9. During the soaking process, the wave absorbing agent in the impregnation liquid can be adsorbed on the inner wall of the honeycomb hole 91 and immersed in the honeycomb structure 9, so that the honeycomb structure 9 has a wave absorbing function, that is, a wave absorbing honeycomb is obtained. After the soaking is completed, the excess impregnation liquid in the honeycomb hole 91 can be poured out.

[0101] It should be noted that, depending on the different parts of the honeycomb structural component 9 that need to be immersed, the number of nozzles 51 can be the same as the number of honeycomb holes 91, that is, multiple nozzles 51 correspond one-to-one to multiple honeycomb holes 91 respectively; the number of nozzles 51 and the number of honeycomb holes 91 may also be different. For example, when the honeycomb structural component 9 only needs to be partially immersed, the number of nozzles 51 can be less than the number of honeycomb holes 91.

[0102] like Fig.17 and Fig.18 As shown, as an embodiment, the wave-absorbing honeycomb impregnation device further includes a brushing device 7, which is located above the blocking device 6. The brushing device 7 includes a lifting drive device 71, a rotating drive device 72 connected to the lifting drive device 71, and a plurality of brush heads 73 connected to the rotating drive device 72, and the plurality of brush heads 73 respectively correspond to the plurality of honeycomb holes 91 on the honeycomb structure 9. The lifting drive device 71 is used to drive the rotating drive device 72 and the plurality of brush heads 73 to move up and down, and the rotating drive device 72 is used to drive the plurality of brush heads 73 to rotate (i.e., rotate along the circumferential direction of the brush heads 73), so that after the brush heads 73 extend into the honeycomb holes 91 on the honeycomb structure 9, the impregnation liquid in the honeycomb holes 91 is stirred by the rotating motion, and the impregnation liquid in the honeycomb holes 91 is evenly brushed on the inner wall of the honeycomb holes 91.

[0103] Specifically, the lifting drive device 71 can be a structure such as a cylinder, an electric cylinder, a linear slide module, etc.; the rotation drive device 72 can be a motor, etc. The number of the rotation drive device 72 can be one, and the one rotation drive device 72 can drive all the brush heads 73 to rotate at the same time through a transmission structure such as a gear or a belt; the number of the rotation drive devices 72 can also be multiple (for example, multiple motors), and the multiple rotation drive devices 72 are respectively connected to the multiple brush heads 73, and the multiple rotation drive devices 72 can independently control each brush head 73 to rotate. The brush head 73 can be a device such as a brush.

[0104] During operation, after the impregnation liquid is sprayed into the honeycomb holes 91 of the honeycomb structure 9 by the liquid spraying device 5, the impregnation liquid is stirred and brushed by the brushing device 7. Specifically, the lifting drive device 71 is first used to drive the rotation drive device 72 and the brush head 73 to move downward, so that the brush head 73 extends into the honeycomb hole 91, and then the rotation drive device 72 is used to drive the brush head 73 to rotate; during the rotation of the brush head 73, on the one hand, the brush head 73 can stir the impregnation liquid so that the precipitated absorber in the impregnation liquid is evenly dispersed in the impregnation liquid (the absorber in the impregnation liquid will settle after standing for a period of time), and on the other hand, the brush head 73 can also brush the absorber on the inner wall of the honeycomb hole 91, thereby improving the attachment efficiency of the absorber. During the immersion process, the brush head 73 can be used to stir and brush the impregnation liquid at regular intervals.

[0105] like Fig.17 and Fig.18 As shown, as an embodiment, the brushing device 7 is located on one side of the liquid spraying device 5 along the horizontal direction X. The wave-absorbing honeycomb impregnation device also includes a horizontal driving device 8, which is connected to the plugging device 6. The horizontal driving device 8 is used to drive the plugging device 6 to move horizontally, so that after the liquid spraying device 5 sprays the impregnation liquid into the honeycomb holes 91 of the honeycomb structure 9, the plugging device 6 and the honeycomb structure 9 are driven to move horizontally, so that the honeycomb structure 9 corresponds to the brushing device 7 up and down, thereby facilitating the brushing device 7 to stir and brush the impregnation liquid. Of course, in other embodiments, the horizontal driving device 8 can also be connected to the brushing device 7 and the liquid spraying device 5 at the same time, and the horizontal driving device 8 is used to drive the brushing device 7 and the liquid spraying device 5 to move horizontally, so as to move the brushing device 7 to correspond to the honeycomb structure 9 up and down. Of course, in other embodiments, the horizontal driving device 8 may not be provided, and after the liquid spraying device 5 sprays the impregnation liquid into the honeycomb holes 91 of the honeycomb structure 9, the plugging device 6 and the honeycomb structure 9 are manually moved to the bottom of the brushing device 7 and aligned. The horizontal driving device 8 can be a structure such as a linear slide rail module.

[0106] like Fig.19 and Fig. 20As shown, as an embodiment, the plugging device 6 includes a bottom plate 61, and a plurality of bosses 62 are arranged at intervals on the upper surface of the bottom plate 61. The bosses 62 are arranged in the same shape as the honeycomb holes 91 (specifically, since the honeycomb holes 91 are hexagonal structures, the bosses 62 are hexagonal prism structures, and the size of the bosses 62 is the same or similar to the size of the honeycomb holes 91). When the honeycomb structure 9 is placed on the bottom plate 61, the bosses 62 can be inserted into the honeycomb holes 91 through the bottom opening of the honeycomb holes 91 to block the bottom opening of the honeycomb holes 91. At the same time, the bosses 62 are generally made of elastic materials (such as silicone, rubber, etc.), so that the bosses 62 have a certain deformation ability, and can better fit and seal with the inner wall of the honeycomb holes 91. Moreover, the height of the bosses 62 should not be too high, generally 1mm to 5mm, or 1mm to 2mm, to prevent the bottom of the honeycomb structure 9 from being effectively soaked by the impregnation liquid.

[0107] like Fig.21 As shown, as an embodiment, the liquid spraying device 5 also includes a liquid storage tank 52, in which the impregnation liquid is stored, and each nozzle 51 is connected to the liquid storage tank 52 through a solenoid valve 53; by controlling the opening and closing of each solenoid valve 53, it is controlled to control whether the corresponding nozzle 51 sprays the impregnation liquid (there is a certain pressure in the liquid storage tank 52, and the impregnation liquid in the liquid storage tank 52 is discharged under the action of pressure).

[0108] like Fig.17 and Fig.18 As shown, as an embodiment, since the nozzle 51 can spray the impregnation liquid into the honeycomb hole 91 from top to bottom, the nozzle 51 does not need to be inserted into the honeycomb hole 91 before spraying the impregnation liquid, that is, the nozzle 51 is separated from the honeycomb structure 9 by a small distance, so there is no need to set a driving device to drive the liquid spraying device 5 to move up and down. Of course, in other embodiments, a driving device (not shown) can also be set, the driving device is connected to the liquid spraying device 5, and the driving device can drive the liquid spraying device 5 to move up and down; when working, the driving device first drives the nozzle 51 to extend downward into the honeycomb hole 91 to spray the impregnation liquid, and after the spraying is completed, the driving device drives the nozzle 51 to retract upward.

[0109] like Figures 17 to 22As shown, as an embodiment, the wave-absorbing honeycomb impregnation device further includes a control module 40, which is respectively connected to each solenoid valve 53, the lifting drive device 71, the rotation drive device 72 and the horizontal drive device 8 by electrical signals. When working, the control module 40 first controls each / part of the solenoid valves 53 to open, so as to spray the impregnation liquid into the honeycomb hole 91 of the honeycomb structure 9; then controls the horizontal drive device 8 to work, and the horizontal drive device 8 drives the blocking device 6 and the honeycomb structure 9 to move horizontally, so that the honeycomb structure 9 corresponds to the brushing device 7 up and down; then controls the lifting drive device 71 to work, so that the brush head 73 extends downward into the honeycomb hole 91, and then controls the rotation drive device 72 to work, and uses the rotation drive device 72 to drive the brush head 73 to rotate, so that the brush head 73 stirs and brushes the impregnation liquid; finally, controls the lifting drive device 71 to drive the brush head 73 to retract upward.

[0110] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
