[0041] The two side walls of the driving bracket 51 are provided with guide slots 52, and the inner walls of one group of the guide slots 52 are slidably connected with a second motor 53, and the output end of the second motor 53 is transmission-connected with a driving gear 54, the driving gear 54 is meshed and connected with a driven gear 37, and the other end of the driving gear 54 is slidably connected to the inner wall of another group of guide slots 52, the bottom of the second motor 53 and the side away from the output end are transmission-connected with the output end of a third electric push rod 55, the bottom of the third electric push rod 55 and the bottom of the driving bracket 51 are both fixedly connected to the test platform 1, the inner wall of the driving bracket 51 is fixedly connected with a display screen power socket 56, and the display screen power socket 56 is electrically connected to the power end of the display screen 7 to be tested, the top of the inner wall of the driving bracket 51 is fixedly connected with a limiting plate 57, and the top of the limiting plate 57 is fixedly connected with a fourth electric push rod 58, the third electric push rod 55 is fixedly connected with the power supply end of the display screen 7 to be tested, and the third electric push rod 55 is fixedly connected with the power supply end of the display screen 7 to be tested. The output ends of the four electric push rods 58 are transmission-connected with an extension block 59, a hinge block 510 is rotatably connected to one side of the top of the driving bracket 51, and a storage tube 511 is embedded and installed on the hinge block 510, one end of the storage tube 511 is provided with a one-way valve 512, and a side wall of the storage tube 511 is provided with a plurality of groups of solenoid valves 513 at the same level and at equal intervals, and a heater 514 is also provided at the end of the storage tube 511 and on the side away from the storage tube 511, two groups of fifth electric push rods 515 are fixedly connected to one side of the outer wall of the driving bracket 51, and the output ends of the two groups of the fifth electric push rods 515 are transmission-connected with a U-shaped rod 516, one end of the two groups of the U-shaped rods 516 are provided with an infrared generator 517, and the other end of the two groups of the U-shaped rods 516 are provided with an infrared receiver 518, and the infrared generator 517, the infrared receiver 518 and the reserved slot 315 are all arranged at the same level.

[0042] Furthermore, the infrared generator 517 and the infrared receiver 518 are both electrically connected to the display screen 33 .

[0043] Specifically, the output end of the third electric push rod 55 drives the second motor 53 to fall, so that the driving gear 54 cancels the meshing connection with the driven gear 37, and the linkage rod 36 is freely rotatably connected in the two sets of hinge seats 35, and the gravity of the two sets of linkage arms 38 is used to swing the color analyzer 39 down between the two sets of clamping plates 313, so as to facilitate the back side of the display screen 7 to be tested to be connected between the two sets of clamping plates 313;

[0044] The output end of the electric slide 2 drives the two groups of first electric push rods 31 to approach each other, and clamps the display screens 7 of different sizes to be tested, so that the two sides and the bottom of the display screen 7 to be tested are firmly installed in the two groups of clamping plates 313;

[0045] The signal output ends of the two groups of infrared generators 517 first penetrate the reserved groove 315 on one side, so that the infrared rays extend into the two groups of clamping plates 313. When the infrared rays penetrate the two groups of clamping plates 313, the infrared rays can pass through the front side of the screen of the display screen 7 to be tested, and form a loop with the infrared receiver 518. When the fifth electric push rod 515 continues to drive the U-shaped rod 516 to move in the direction close to the fifth electric push rod 515, the infrared rays emitted by the infrared generator 517 also move synchronously. When the infrared rays emitted by the infrared generator 517 are not received by the infrared receiver 518 at the same level, and the infrared rays are obviously irradiated on the protruding display screen 7 to be tested, it will be judged that the flatness and appearance of the display screen 7 to be tested do not meet the requirements;

[0046] After the linkage arm 38 is manually adjusted to a horizontal position by the operator, the third electric push rod 55 is used to push up the second motor 53 again, so that the driving gear 54 is meshed and connected with the driven gear 37. When the second motor 53 drives the driving gear 54 to rotate, the clamping plate 313 and the display screen 7 to be tested are rotated around the driven gear 37, and the display screen 7 to be tested is adjusted to the installation angle of the simulated smart plastic runway display screen, and the output end of the fourth electric push rod 58 is used to push the storage tube 511, so that the storage tube 511 is adjusted according to the rotation angle of the hinge block 510, and several groups of solenoid valves 513 are moved to the top of the display screen 7 to be tested after the angle is adjusted, and the continuous operation of the water pump in the hose 6 is used to transfer the rainwater in the water tank 4 to the storage tube 511, and the opening of several groups of solenoid valves 513 is used to flush the rainwater from the top of the display screen 7 to be tested downwards, which is used to simulate the water resistance aging test of the display screen 7 to be tested, and the flushed rainwater flows into the water tank 4 again;

[0047] The continuous operation of the heater 514 forms a closed space in the storage tube 511 under the action of the one-way valve 512. By opening a plurality of sets of electromagnetic valves 513, the warm air generated by the heater 514 is blown from the top to the bottom of the display screen 7 to be tested, so as to simulate the high temperature aging test of the display screen 7 to be tested.

[0048] The output end of the first motor 312 drives the screw rod 310 to rotate, so that the color analyzer 39 threadedly connected to the screw rod 310 moves horizontally, which is used to perform accurate color analysis on different positions of the display screen 7 to be tested, and test the color state of the display screen when the display screen is continuously lit for more than 72 hours, and detect whether the display screen has any abnormalities during long-term operation, which is conducive to improving stability during later use.

[0049] The working principle of the aging test device for a smart plastic runway display screen proposed in the embodiment of the present invention is as follows:

[0050] First, the output end of the third electric push rod 55 drives the second motor 53 to fall, so that the driving gear 54 cancels the meshing connection with the driven gear 37, and the linkage rod 36 is freely rotatably connected in the two sets of hinge seats 35, and the gravity of the two sets of linkage arms 38 is used to swing the color analyzer 39 down between the two sets of clamping plates 313, so as to facilitate the back side of the display screen 7 to be tested to be connected between the two sets of clamping plates 313;

[0051] In the process of driving the two groups of first electric push rods 31 to approach each other through the output end of the electric slide 2, the display screens 7 to be tested of different sizes are clamped, so that the two sides and the bottom of the display screen 7 to be tested are firmly installed in the two groups of clamping plates 313;

[0052] The signal output end of the infrared generator 517 first penetrates the reserved groove 315 on one side, so that the infrared rays extend into the two groups of clamping plates 313. When the infrared rays penetrate the two groups of clamping plates 313, the infrared rays can pass through the front side of the screen of the display screen 7 to be tested, and form a loop with the infrared receiver 518. When the fifth electric push rod 515 continuously drives the U-shaped rod 516 to move in the direction close to the fifth electric push rod 515, the infrared rays emitted by the infrared generator 517 also move synchronously. When the infrared rays emitted by the infrared generator 517 are not received by the infrared receiver 518 at the same level, and the infrared rays are obviously irradiated on the protruding display screen 7 to be tested, it will be judged that the flatness and appearance of the display screen 7 to be tested do not meet the requirements;

[0053] After the operator manually adjusts the linkage arm 38 to a horizontal position, the third electric push rod 55 is used to push up the second motor 53 again, so that the driving gear 54 is meshed and connected with the driven gear 37. When the second motor 53 drives the driving gear 54 to rotate, the clamping plate 313 and the display screen 7 to be tested are rotated around the driven gear 37, and the display screen 7 to be tested is adjusted to the installation angle of the simulated smart plastic runway display screen, and the output end of the fourth electric push rod 58 is used to push the storage tube 511, so that the storage tube 511 is adjusted according to the rotation angle of the hinge block 510, and several groups of solenoid valves 513 are moved to the top of the display screen 7 to be tested after the angle is adjusted, and the continuous operation of the water pump in the hose 6 is used to transfer the rainwater in the water tank 4 to the storage tube 511, and the opening of several groups of solenoid valves 513 is used to flush the rainwater from the top of the display screen 7 to be tested downwards, which is used to simulate the water resistance aging test of the display screen 7 to be tested, and the flushed rainwater flows into the water tank 4 again;

[0054] Through the continuous operation of the heater 514, under the action of the one-way valve 512, a closed space is formed in the storage tube 511, and by opening a plurality of sets of electromagnetic valves 513, the warm air generated by the heater 514 is blown from the top to the bottom of the display screen 7 to be tested, so as to simulate the high temperature aging test of the display screen 7 to be tested;

[0055] The output end of the first motor 312 drives the screw rod 310 to rotate, so that the color analyzer 39 threadedly connected to the screw rod 310 moves horizontally, which is used to perform accurate color analysis on different positions of the test display screen 7, and test the color state of the display screen when the display screen is continuously lit for more than 72 hours, and detect whether the display screen has any abnormalities during long-term operation, which is conducive to improving the stability during later use.

[0056] Based on the above-mentioned aging test device for a smart plastic runway display screen, an embodiment of the present invention further provides a method for using the aging test device for a smart plastic runway display screen, comprising the following steps:

[0057] The electric slide drives the positioning test assembly to connect the transmission, which is used to clamp the display screens to be tested of different sizes, so that the display screens to be tested are in a stable test state;

[0058] The position of the display screen to be tested on the positioning test component is adjusted by the driving component, so that the adjusted display screen to be tested is at the installation angle of the smart plastic runway;
