[0002] With the continuous advancement of LED display technology, LED displays have been widely used in various fields, including commercial advertising, information dissemination, and entertainment performances. In these applications, LED displays not only need to have good display effects and stability, but also need to withstand various complex operating environments.

[0003] Existing LED display screen abrasion resistance testing devices typically involve fixing the LED display screen on a test platform and then using a test grinding wheel to induce wear on the LED display screen for abrasion resistance testing. However, due to the limited functionality of current devices, they cannot simulate the abrasion resistance of LED display screens during movement and at different tilt angles, making it difficult to comprehensively evaluate mechanical strength and structural stability.

[0004] Therefore, it is necessary to design a wear resistance testing device for finished LED displays that can be moved and subjected to wear resistance tests at different tilt angles and temperatures, so as to simulate collisions in daily life and comprehensively evaluate mechanical strength and structural stability. Utility Model Content

[0005] To overcome the shortcomings of current devices that are limited in function, unable to simulate the wear resistance of LED displays during movement and at different tilt angles, and not convenient for comprehensively evaluating mechanical strength and structural stability, this utility model provides a finished LED display wear resistance testing device that can conduct wear resistance tests by moving the LED display and under different tilt angles and temperature environments, facilitating the simulation of collisions in daily life and comprehensively evaluating mechanical strength and structural stability.

[0006] The technical solution is as follows: A wear resistance testing device for a finished LED display screen includes a base plate, a connecting seat, a lead screw, a common motor, a first support column, a servo motor, electric grippers, and testing components. The connecting seat is connected to the upper side of the base plate, and the lead screw is rotatably connected to the middle of the connecting seat. The common motor is connected to the right side of the connecting seat, and the output shaft of the common motor is connected to the lead screw. The first support column is slidably connected to both the left and right sides of the connecting seat. The first support column on the right side is threadedly connected to the lead screw. The servo motor is connected to the inner side of the upper part of the first support column, and the electric grippers are connected to the output shafts of the servo motors. An LED display screen is clamped between the electric grippers. The base plate is equipped with testing components capable of conducting wear resistance tests on the LED display screen.

[0007] As an improvement to the above solution, the test assembly includes a second support column, a damping telescopic rod, a drive motor, and a test grinding disc. The second support column is connected to the upper rear side of the base plate, the damping telescopic rod is connected to the front of the second support column, the drive motor is connected to the telescopic end of the damping telescopic rod, and the test grinding disc is connected to the output shaft of the drive motor.

[0008] As an improvement to the above scheme, a waste tray is also included, with the waste tray connected between the lower parts of the first support columns.

[0009] As an improvement to the above solution, rubber pads are also included, with rubber pads connected to both the upper and lower parts of the electric gripper.

[0010] As an improvement to the above scheme, an infrared lamp is also included, with an infrared lamp connected to the upper side of the first support column on the right.

[0011] As an improvement to the above scheme, a water sprayer is also included, with the water sprayer connected to the upper side of the first support column on the left.

[0012] Beneficial effects: 1. This utility model uses a common motor to drive the lead screw to rotate, which in turn moves the LED display screen. Then, a servo motor drives the electric chuck to rotate, which adjusts the angle of the LED display screen. Heat is dissipated by infrared lamps. This allows the LED display screen to move and wear resistance tests to be conducted under different tilt angles and temperature conditions. This is convenient for simulating collisions in daily life and comprehensively evaluating the mechanical strength and structural stability.

[0013] 2. This utility model sprays water onto the LED display screen using a water sprayer, causing debris and water to be discharged into a waste tray. Then, the first support column is moved by the rotation of the lead screw, adjusting the position of the LED display screen so that the test grinding disc is aligned with the untested position, and then the wear resistance test is carried out. This achieves the effect of conveniently removing debris generated on the LED display screen and facilitating the rapid testing of the next position of the LED display screen.

The connecting seat 2 is connected to the upper side of the base plate 1. The lead screw 3 is rotatably connected to the middle of the connecting seat 2. The conventional motor 4 is connected to the right side of the connecting seat 2, and the output shaft of the conventional motor 4 is connected to the lead screw 3. The first support column 5 is slidably connected to both the left and right sides of the connecting seat 2. The right side of the first support column 5 is threadedly connected to the lead screw 3. The first support column 5 is located below... The parts are connected by a waste tray 6. The upper inner side of the first support column 5 is connected to a servo motor 7. The output shaft of the servo motor 7 is connected to an electric chuck 8. The upper and lower parts of the electric chuck 8 are connected to rubber pads 9. An LED display screen 10 is clamped between the electric chuck 8. The upper side of the first support column 5 on the right is connected to an infrared lamp 11. The upper side of the first support column 5 on the left is connected to a water sprayer 12. The upper rear side of the base plate 1 is connected to a second support column 13. The front of the second support column 13 is connected to a damping telescopic rod 14. The telescopic end of the damping telescopic rod 14 is connected to a drive motor 15. The output shaft of the drive motor 15 is connected to a test grinding disc 16.

[0022] When using this device, first place the base plate 1 in the wear resistance test area of ​​the LED display screen 10, then place the LED display screen 10 between the rubber pads 9, and then clamp and fix the LED display screen 10 with the electric gripper 8. Next, adjust the height of the test grinding disc 16 using the damping telescopic rod 14 so that the test grinding disc 16 contacts the LED display screen 10. Then, start the drive motor 15 to rotate the test grinding disc 16, generating friction between the test grinding disc 16 and the LED display screen 10 for wear resistance testing. Afterwards, start the ordinary motor 4 to rotate the lead screw 3, causing the right first support column 5 to move under the action of the thread, so that the left first support column 5 moves on the connecting seat 2, causing the LED display screen 10 to move left and right. Then, simulate grinding using the test grinding disc 16. Alternatively, the servo motor 7 can be started to rotate the electric gripper 8, causing the LED display screen 10 to rotate and adjust... The tilt angle of the LED display screen 10 is adjusted, and then the test grinding disc 16 is used to simulate grinding. At the same time, the infrared lamp 11 emits heat to simulate experiments under different temperature conditions. This allows for wear resistance tests to be conducted by moving the LED display screen 10 and at different tilt angles and temperature environments. This is convenient for simulating collisions in daily life and for comprehensively evaluating mechanical strength and structural stability. When wear resistance tests are required on different positions of the LED display screen 10, water can be sprayed onto the LED display screen 10 using the water sprayer 12. The debris and water generated during the test are discharged into the waste tray 6. Then, the first support column 5 is moved by rotating the lead screw 3 to adjust the position of the LED display screen 10 so that the test grinding disc 16 is aligned with the untested position before the wear resistance test is conducted. This makes it easy to remove debris generated on the LED display screen 10 and facilitates quick testing on the next position of the LED display screen 10.
