[0002] Aviation transparent parts usually need to be coated. Coating can form a protective layer or conductive layer on the surface of the transparent parts, play the role of anti-static, protective shell, etc., increase the transmittance of transparent parts to light of specific wavelengths, thereby reducing light reflection loss and improving light transmission efficiency. Through coating technology, it is possible to filter specific wavelengths of light, thereby avoiding harmful light from damaging the pilot's eyes or instruments and equipment, and improving the thermal stability of transparent parts.

[0003] Therefore, the quality of coating is directly related to the safe operation of aircraft. Coating products usually need to be tested for performance. Because the working environment of aviation transparent parts has thin air and strong solar radiation, which is quite different from the surface environment, it is necessary to test the tolerance and aging of the film layer in a high temperature and low pressure environment to provide data support for the optimization of transparent parts coating process.

[0004] The test of existing coated products is carried out under surface pressure. The test structure deviates from the actual situation. The workpiece test bench can only realize three-dimensional activities and there are blind spots in the test. Especially for special-shaped coated products, it is impossible to adjust the optimal angle to face the thermal radiation equipment and realize the three-dimensional spatial flipping of the coated products.

[0035] For example, if the second carrier plate 33 and the first carrier 35 perform mutually perpendicular translational motion in the horizontal plane, the second carrier 37 performs lifting motion in the vertical plane to achieve three-dimensional translation, the third carrier plate 38 rotates in the horizontal plane, and the workpiece mounting plate 312 rotates in the vertical plane. At this time, the first carrier plate 31 can be directly installed horizontally in the cabin 1, or the first carrier plate 31 can be installed in the cabin 1 in the horizontal direction through an intermediate support member and / or an intermediate lifting member.

[0036] For example, if the second carrier plate 33 and the first carrier 35 perform mutually perpendicular translational motion in the vertical plane, the second carrier 37 performs translational motion in the horizontal plane to achieve three-dimensional translation, the third carrier plate 38 rotates in the vertical plane, and the workpiece mounting plate 312 rotates in the horizontal plane. At this time, the first carrier plate 31 can be directly installed in the cabin body 1 in the vertical direction, or the first carrier plate 31 can be installed in the cabin body 1 in the vertical direction through an intermediate support member and / or an intermediate hanging member.

[0037] Of course, the first carrier plate 31 may be neither in the horizontal plane nor in the vertical plane, but may be tilted. The first carrier plate 31 may be installed in the cabin 1 through an intermediate support member and / or an intermediate lifting member, so that the first carrier plate 31 is tilted. The installation angles of other components follow the installation angle of the first carrier plate 31, and the angle rule is consistent with the above exemplary description.

[0038] The above-mentioned intermediate support members and intermediate lifting members are selected from commonly used structures in the prior art according to the application scenarios.

The two ends of the heating tube 62 are connected to the corresponding electrode strip 64 through an electrode line 63, and the electrode strip 64 is connected to a vacuum feeding electrode 65. The vacuum feeding electrode 65 is a sealing device, and its structure can refer to the structure in the prior art, and will not be described in detail. It can pass through the vacuum cabin 1, transmit the electric power, electric signal, etc. at the atmospheric end to the interior of the cabin 1, and energize the heating tube 62 and pass the control signal.

[0040] Specifically, the heating tube 62 is an IR quartz heating tube, both ends of which are mounted on the bottom plate of the mounting frame 61 through clips 66 , and both ends of the heating tube 62 extend out of the side plates of the mounting frame 61 and are connected to corresponding electrode strips 64 located outside the mounting frame 61 through electrode wires 63 .

The vacuum pump 41 can be a dry vacuum pump in the prior art. Starting the dry vacuum pump can enable the cabin 1 to obtain a vacuum environment with a limit of about 100Pa. The vacuum valve 42 is used to adjust the airflow, cut off or connect the pipeline, so as to achieve the regulation and control of the vacuum degree in the cabin 1. When the vacuum valve 42 is closed, the gas in the cabin 1 cannot escape from the vacuum valve 42, so as to maintain the vacuum degree in the cabin. When the vacuum valve 42 is opened, the vacuum pump 41 starts to pump air, so as to change the vacuum degree in the cabin 1. By adjusting the opening of the vacuum valve 42, the pumping speed of the vacuum pump 41 can be controlled, so as to achieve the precise regulation of the vacuum degree in the cabin. The utility model does not involve the improvement of the structure of the vacuum valve 42. The specific structure of the vacuum valve 42 can refer to the prior art.

Pushing and pulling the handle can rotate the hatch 2 to realize opening and closing of the hatch 2. A sealing strip is provided on one side of the hatch 2 and the cabin 1 to ensure that when the hatch 2 is closed, the interior of the cabin 1 is a sealed environment and no gas leakage occurs. A thermocouple 13 is installed in the thermocouple feed port 21, and the thermocouple feed port 21 is used to feed the signal of the thermocouple 13 from the interior of the cabin 1 to the outside while maintaining the sealing of the cabin 1. Thermocouples 13 are arranged at multiple positions in the cabin 1 to feedback the real-time temperature of various places in the cabin 1.

[0045] The observation window 12 can be used to understand the situation in the cabin 1 and observe whether the height, angle, and distance between the coating product 313 to be tested and the heating component 6 are appropriate.

[0048] The attitude simulation turntable 3 can be manually adjusted in three dimensions, and the coated product 313 to be tested is adjusted to a suitable position relative to the heating component 6. The cabin door 2 is closed, and the electronic control system 5 starts the vacuum pump 41. The vacuum gauge 11 feeds back the pressure in the cabin 1 to the electronic control system 5 in real time until the pressure in the cabin 1 is pumped to a preset vacuum value, and the vacuum valve 42 is closed. The electronic control system 5 controls the vacuum feeding electrode 65 to be energized, and the heating tube 62 irradiates the coated product 313 to be tested. The electronic control system 5 controls the first vacuum motor 36, the second vacuum motor 39, and the third vacuum motor 311 to cooperate to realize the lifting and flipping of the coated product 313 to be tested, so that the coated product 313 to be tested faces the heating tube 62 at the optimal angle, so as to test the heating radiation performance and state of the coated product 313 to be tested. The heating component 6 adopts PID control, and the required heating temperature can be controlled according to the test requirements.

[0049] It should be noted that the first driving screw rod 32 and the second driving screw rod 34 may also be connected to the motor. By driving the motor, the motor and the electronic control system 5 are associated to realize the fully automatic adjustment of the posture simulation turntable 3 .

[0050] It should be noted that the state of the coated product 313 to be tested in the chamber 1 can be set according to the test requirements. The coated product 313 to be tested can be stopped at a certain angle to receive the thermal radiation of the heating component 6, or the coated product 313 to be tested can be turned over in the middle, or the coated product 313 to be tested can be turned over continuously to evenly receive the thermal radiation of the heating component 6.

Specifically, cooling channels are provided in the side walls and end walls of the cabin 1 and the wall of the mounting frame 61. The cooling channels are provided with a liquid inlet and a liquid outlet. The cooling liquid outside the cabin 1 is input into the cooling channels through the liquid inlet.

A liquid cooling pipe is also provided in the vacuum pump 41. A delivery pipe is provided outside the vacuum pump 41 to deliver the cooling liquid into the vacuum pump 41, and then the cooling liquid is discharged from the vacuum pump 41 to achieve cooling of the vacuum pump 41. The vacuum valve 42 is opened to break the air in the cabin 1. The liquid cooling system can continue to cool the cabin 1 and the mounting frame 61 until the temperature is suitable, and then the cabin door 2 is opened to remove the coated product 313 to be tested. In some embodiments, a base 7 is also included to provide support for the cabin 1.
