[0045] Please refer to Figures 1-7 In the embodiment of the present application, a surface salt mist corrosion resistant spraying device for a ship electrical component comprises:

[0046] The workbench 1 is provided with a protective cover 11 on the top;

[0047] The positioning turntable 2 is rotationally arranged on the workbench 1;

[0048] The mechanical arm 3 is fixed on the bottom of the upper protective cover 11 through a connecting seat;

[0049] The spraying device 4 is fixed on the mechanical arm 3;

[0050] The air curtain device 5 is rotationally arranged on the spraying device 4.

[0051] In this embodiment, the positioning turntable 2 comprises:

[0052] The rotating table 21 is rotationally arranged on the workbench 1, and the center of the rotating table 21 is on the same vertical line as the center of the connecting seat of the mechanical arm 3;

[0053] The positioning groove 22 is located at the center of the rotating table 21;

[0054] The slide 23 is annularly arranged with a plurality of slide grooves, which are arranged on the rotating table 21 and located outside the positioning groove 22, and the bottom plane of the slide 23 is on the same horizontal plane as the positioning groove 22;

[0055] The clamping block 24 is arranged corresponding to the slide 23 and is slidingly arranged in the slide 23.

[0056] That is, the workbench 1 serves as a basic bearing platform, the surface of which is paved with an anti-static ceramic coating, the protective cover 11 is made of transparent polycarbonate material, forming a closed spraying environment, isolating the paint flying during the spraying process, ensuring safety and environmental protection, and during spraying, the ship electrical components are placed in the positioning groove 22, then the clamping blocks 24 in the slide 23 are radially contracted or expanded synchronously according to the size of the workpiece to clamp and fix the workpiece, under the clamping cooperation of the plurality of clamping blocks 24, the electrical components are effectively prevented from shaking during the spraying process, after the electrical components are fixed, the positioning turntable 2 is driven by the motor to rotate around the center axis on the workbench 1, cooperating with the axial movement of the mechanical arm 3 to realize the omnidirectional exposure of the surface of the workpiece. Ensure that the surface of the component is evenly sprayed.

[0057] In this embodiment, the spraying device 4 comprises:

[0058] The connecting arm 41 is fixed on the mechanical arm 3;

[0059] The spray gun 42 is fixedly connected with the connecting arm 41 and corresponds to the positioning turntable 2.

[0060] That is, under the drive of the mechanical arm 3, the three-dimensional position of the spray gun 42 is controlled through multi-joint movement, and complex trajectory spraying is realized by cooperating with the rotation of the positioning turntable 2, the spray gun 42 adopts high-pressure air atomization technology to uniformly spray the anticorrosive paint to the surface of the component, effectively reducing paint waste through atomization spraying, improving the compactness and adhesion of the coating, and shortening the operation cycle through automatic spraying throughout the process, reducing the risk of manual intervention.

[0061] In this embodiment, the air curtain device 5 comprises:

[0062] The rotating ring 51 is rotatably arranged on the connecting arm 41.

[0063] The air curtain control area 52 is annularly distributed and fixed on the rotating ring 51.

[0064] That is, under the rotation of the rotating ring 51, the air curtain control area 52 rotates around the axis of the spray gun 42 to form a dynamic protective barrier around the spray gun 42, effectively preventing paint splashing and ensuring uniform coverage of the device surface. In the static state of the rotating ring 51, the air curtain control area 52 can also be controlled to produce uniform air distribution, and more flexible air control can be achieved by adjusting the air pressure of each air curtain control area 52, thereby optimizing the deposition effect of the paint in a specific area. When adjusting the air pressure of the air curtain control area 52, the rotating ring 51 can be rotated to adjust the range covered by each air curtain control area 52 to achieve more accurate spraying effect.

[0065] In this embodiment, the air curtain control area 52 comprises:

[0066] The displacement adjusting assembly 521 is fixed on the outer ring of the rotating ring 51.

[0068] The nozzle 523 is fixed on the angle adjusting assembly 522.

[0069] That is, the range of the nozzle 523 is adjusted by the displacement adjusting assembly 521, and the angle of the nozzle 523 is adjusted by the angle adjusting assembly 522 to adapt to the protection needs of devices of different sizes.

[0070] In this embodiment, the displacement adjusting assembly 521 comprises:

When the angle adjusting assembly 522 moves on the displacement channel 5213 in a direction away from the rotating ring 51, the nozzle 523 is away from the spray gun 42, and the effective range of the nozzle 523 is larger. When the angle adjusting assembly 522 moves on the displacement channel 5213 in a direction towards the rotating ring 51, the nozzle 523 is close to the spray gun 42, and the effective range of the nozzle 523 is smaller. And under the limitation of the limiting transverse plate 5214, the movement range of the angle adjusting assembly 522 on the displacement channel 5213 is limited.

[0076] In this embodiment, the control partition plate 5211 is internally provided with a control mechanism, and the driving angle adjusting assembly 522 moves in the displacement channel 5213.

[0081] The telescopic shaft 5224 is connected to the universal joint 5223 and the nozzle 523.

[0082] That is, the push shaft 5222 is controlled to move in the adjusting ring 5221 by the adjusting ring 5221, and the position between the nozzle 523 and the spray gun 42 is further adjusted. Under the action of the universal joint 5223, the pitch angle and azimuth angle of the nozzle 523 are adjusted with two degrees of freedom, and the position of the nozzle 523 is adjusted again by the telescopic shaft 5224. Through multi-stage adjustment and two-degree-of-freedom angle adjustment, comprehensive and accurate spraying of various workpieces is realized.

[0084] As a preferred embodiment, for components that need to be uniformly sprayed, the six air curtain control areas 52 are synchronously adjusted, the same air pressure and nozzle 523 position are maintained, and it is ensured that the paint uniformly covers the surface of the component; for components containing local sensitive areas, the air pressure of the air curtain control area 52 corresponding to the sensitive area is reduced to reduce the deposition of the paint, the air pressure of the air curtain control area 52 corresponding to the target area is increased to increase the amount of paint adhesion, and the performance of the coating is improved; for components with complex shapes or deep hole structures, the direction of the nozzle 523 in a specific air curtain control area 52 is adjusted to form directional air flow, the air pressure in the local control area is increased, the penetration of the paint is enhanced, and the paint is guided to the inside of the groove or deep hole; for components that need gradient coating performance, according to the performance requirements, the air pressure and paint flow are independently adjusted, the air pressure and paint concentration are increased in the high-performance requirement area, and the air pressure and paint concentration are reduced in the low requirement area, according to different component characteristics, the air curtain control area 52 is precisely adjusted, the air flow parameters are flexibly adjusted, and the best spraying effect is achieved.
