[0025] like Figures 1 to 3As shown, a radome processing spraying device described in an embodiment of the present invention includes a spray box 1; a paint box 11 is fixedly connected to the top of the spray box 1; a spray pipe 12 is fixedly connected to the side wall of the paint box 11; the middle part of the spray pipe 12 passes through the top of the spray box 1; two nozzles 13 are fixedly connected to the end of the spray pipe 12; the two nozzles 13 are arranged oppositely; a sliding platform 10 is slidably connected to the bottom of the spray box 1; the sliding platform 10 is slidably connected to the inside of the spray box 1; the middle part of the sliding platform 10 is hollow; the sliding A motor 14 is fixedly connected to the middle of the moving table 10; the output end of the motor 14 passes through the top of the sliding table 10; the output end of the motor 14 is fixedly connected to a base 15; a plurality of slide grooves 16 are provided on the top of the base 15; a slider 17 is slidably connected to the middle of the slide groove 16; a spring 18 is fixedly connected to the side wall of the slider 17; the end of the spring 18 is fixedly connected to one end of the slide groove 16; a fixing rod 19 is fixedly connected to the top of the slider 17; when working, the sliding table 10 is pulled out from the inside of the spray box 1, and the sliding table 10 slides inside the spray box 1 to move the antenna The cover is placed on the base 15 from the top of the fixing rod 19, so that the multiple fixing rods 19 are in contact with the inner wall of the antenna cover. The inner wall of the antenna cover applies pressure to the multiple fixing rods 19. After the fixing rods 19 are under pressure, they slide inside the slide groove 16 through the slider 17. When the slider 17 moves, the spring 18 elastically expands and contracts, and the antenna cover is fixed to the base 15 through the multiple fixing rods 19. Then, the sliding platform 10 is pushed into the interior of the spray box 1, and the motor 14 is powered on and turned on to rotate the output end of the motor 14, while driving the base 15 to rotate the antenna cover. The spraying tube 12 is controlled to spray the radome, and the inside of the radome can be fixed during the spraying process through the fixing rod 19, so that the paint can be evenly sprayed on the surface of the radome, which can effectively reduce the problem of uneven spraying or omissions on the surface of the radome, and can effectively reduce the movement or shaking of the radome during the spraying process, and can rotate the base 15 to make all parts of the radome fully sprayed, effectively making the paint evenly distributed on the surface of the radome, which can effectively improve the spraying efficiency and quality of the radome.

[0026] like Figures 1 to 3 As shown, two fixing blocks 2 are fixedly connected to the middle part of the fixing rod 19; an elastic plate 21 is fixedly connected to the end of the fixing block 2; the elastic plate 21 is arranged in an arc shape; when working, when the antenna cover is fixed by multiple fixing rods 19, it contacts the inner wall of the antenna cover through the elastic plate 21, and the elastic plate 21 is bent by elasticity and fits tightly with the inner wall of the antenna cover. The elasticity of the elastic plate 21 can increase the contact area between the fixing rod 19 and the antenna cover, so that the elastic plate 21 can fit tightly with the inner wall of the antenna cover, and can increase the friction between the antenna cover and the fixing rod 19, thereby effectively improving the stability of the antenna cover during the spraying process, and can reduce the problem of the fixing rod 19 scratching or wearing the inner wall of the antenna cover during the spraying process, and effectively reduce the damage to the antenna cover during the spraying process.

[0027] like Figure 1 and Figure 4 As shown, the top of the spray box 1 is fixedly connected to an air pump 3; the side wall of the air pump 3 is fixedly connected to a first connecting pipe 31; the end of the first connecting pipe 31 is fixedly connected to a first exhaust pipe 32; the first exhaust pipe 32 is U-shaped; the first exhaust pipe 32 is fixedly connected to the side wall of the spray box 1; two groups of exhaust holes 33 are opened in the middle of the first exhaust pipe 32; the two groups of exhaust holes 33 are arranged opposite to each other; when working, the air pump 3 is powered on and turned on, so that the air flow inside the air pump 3 is discharged to the first connecting pipe 31, and the air flow is discharged to the inside of the first exhaust pipe 32 through the end of the first connecting pipe 31. , and then the airflow is discharged through multiple sets of exhaust holes 33. When the antenna cover is fixed, the sliding platform 10 is pushed into the interior of the spray box 1. When the antenna cover passes through the exhaust holes 33, the airflow blows to the surface of the antenna cover. Discharging the airflow through the exhaust holes 33 can effectively remove dust and impurities on the surface of the antenna cover, and can effectively reduce the formation of uneven spots or protrusions on the surface of the antenna cover by dust and impurities, effectively reduce the insufficient adhesion of the paint on the surface of the antenna cover, and cause the coating to peel off or crack during use. It can effectively increase the adhesion between the coating and the antenna cover, thereby improving the durability and stability of the coating.

[0028] like Figure 1 、 Figure 4 、 Figure 6 As shown, the middle of the first exhaust pipe 32 is fixedly connected to the second connecting pipe 4; the end of the second connecting pipe 4 is fixedly connected to the second exhaust pipe 41; the second exhaust pipe 41 is U-shaped; the second exhaust pipe 41 is fixedly connected to the middle position of the spray box 1; two through grooves 42 are provided in the middle of the second exhaust pipe 41; the two through grooves 42 are arranged opposite to each other; two heating wires 43 are fixedly connected to the middle of the second exhaust pipe 41; the heating wires 43 are fixedly connected to the corresponding through grooves 42; when working, during the spraying process of the antenna cover, the airflow inside the first exhaust pipe 32 is discharged to the outside through the second connecting pipe 4. Inside the second exhaust pipe 41, the heating wire 43 is turned on to generate heat on the surface. When the airflow passes through the heating wire 43, the heat causes the airflow to heat up. The heated airflow is discharged to the antenna cover spraying position through the through groove 42. By discharging the hot airflow to the antenna cover spraying surface, the temperature of the antenna cover spraying surface can be effectively increased, thereby accelerating the evaporation of the solvent or water in the coating, and enabling the solvent or water in the coating to evaporate evenly, reducing the coating defects caused by uneven local drying of the antenna cover, effectively reducing the generation of bubbles on the antenna cover coating surface, allowing the coating to dry quickly, and effectively improving the efficiency of the antenna cover spraying.

[0029] like Figure 1 、 Figure 4 、 Figure 5As shown, two groups of slide rails 5 are fixedly connected to the middle of the first exhaust pipe 32; each two of the slide rails 5 form a group; a slide plate 51 is slidably connected to the middle of the two slide rails 5; a sealing gasket 52 is fixed to the middle of the slide plate 51; when working, the slide plate 51 is rotated in the middle of the slide rail 5, and the slide plate 51 is moved to the position of multiple groups of exhaust holes 33, and the multiple groups of exhaust holes 33 are blocked and sealed by the sealing gasket 52, so that the airflow cannot be discharged from the exhaust hole 33 position, and the direction and intensity of the airflow can be effectively adjusted by the slide plate 51 and the sealing gasket 52, so that the airflow can flow according to the predetermined path and speed, effectively increasing the intensity of the airflow discharged through the through slot 42, and effectively reducing the dispersion of the airflow, thereby effectively reducing the unnecessary energy consumption and waste caused by the loss of airflow.

[0030] like Figures 1 to 3 As shown, a connecting rod 6 is fixed to the top of the fixing rod 19; a rubber pad 61 is fixed to the end of the connecting rod 6; during operation, after the radome is placed from the top of the fixing rod 19, it fits with the top of the radome through the rubber pad 61. The rubber pad 61 can effectively absorb the impact of the fixing rod 19 on the top of the radome, effectively reducing the problem of damage or deformation of the top of the radome caused by the impact, and can keep the radome stable on the top of the fixing rod 19, which can effectively provide additional protection for the radome and reduce damage to the radome during the spraying process.

[0031] like Figure 1 and Figure 4 As shown, a heat preservation cover 7 is fixedly connected to the middle of the heating wire 43; the heat preservation cover 7 is fixedly connected to the outside of the heating wire 43; a plurality of through holes 71 are provided in the middle of the heat preservation cover 7; a plurality of through holes 71 are provided at the positions corresponding to the through slots 42; during operation, the heat generated on the surface of the heating wire 43 is insulated by the heat preservation cover 7, and in the process of spraying the antenna cover, the heat preservation cover 7 is used to prevent the paint from splashing onto the surface of the heating wire 43, and the airflow discharged from the through slots 42 is discharged through the plurality of through holes 71. The heat preservation cover 7 can effectively reduce the paint from splashing onto the surface of the heating wire 43 during the spraying of the antenna cover, effectively reduce the paint from solidifying and forming lumps on the surface of the heating wire 43, reduce the heat conduction efficiency during the use of the heating wire 43, effectively reduce the damage rate of the heating wire 43 during the use, and can effectively reduce the heat loss on the surface of the heating wire 43, and reduce unnecessary energy waste.

[0032] During operation, the sliding platform 10 is pulled out from the inside of the spray box 1, and the sliding platform 10 slides inside the spray box 1. The antenna cover is placed on the base 15 from the top of the fixing rod 19, so that the multiple fixing rods 19 are in contact with the inner wall of the antenna cover. The inner wall of the antenna cover applies pressure to the multiple fixing rods 19. After the fixing rods 19 are pressed, they slide inside the slide groove 16 through the slider 17. When the slider 17 moves, the spring 18 elastically expands and contracts, and the antenna cover is fixed to the base 15 through the multiple fixing rods 19. Then the sliding platform 10 is pushed into the spray box 1. After the motor 14 is powered on, it is turned on to rotate the output end of the motor 14, and at the same time, the base 15 is driven to rotate the antenna cover, and the spray pipe 12 is controlled to spray the antenna cover. When the antenna cover is fixed by multiple fixing rods 19, it contacts the inner wall of the antenna cover through the elastic plate 21. The elastic plate 21 is bent by elasticity and fits tightly with the inner wall of the antenna cover. After the air pump 3 is powered on, it is turned on to discharge the air flow inside the air pump 3 to the first connecting pipe 31. The air flow is discharged to the inside of the first exhaust pipe 32 through the end of the first connecting pipe 31. The airflow is then discharged through multiple sets of exhaust holes 33. After the radome is fixed, the sliding platform 10 is pushed into the spray box 1. When the radome passes through the exhaust holes 33, the airflow blows toward the surface of the radome. During the spraying process of the radome, the airflow inside the first exhaust pipe 32 is discharged to the inside of the second exhaust pipe 41 through the second connecting pipe 4. The heating wire 43 is turned on to generate heat on the surface. When the airflow passes through the heating wire 43, the heat causes the airflow to heat up. The heated airflow is discharged to the spraying position of the radome through the through slot 42. The slide plate 51 is positioned in the middle of the slide rail 5. Rotate the slide plate 51 to the position of multiple groups of exhaust holes 33, block and seal the multiple groups of exhaust holes 33 through the sealing gasket 52, so that the airflow cannot be discharged from the exhaust holes 33. After the antenna cover is placed on the top of the fixing rod 19, it is fitted with the top of the antenna cover through the rubber pad 61, and the heat generated on the surface of the heating wire 43 is insulated by the heat preservation cover 7. In the process of spraying the antenna cover, the heat preservation cover 7 prevents the paint from splashing onto the surface of the heating wire 43, and the airflow discharged from the through groove 42 is discharged through the multiple groups of through holes 71.
