Description

Technical Field

[0001] The invention relates to the technical field of durability experiments, and in particular to a durability experiment device for a washing machine touch screen. Background Art

[0002] Most home appliances need to undergo quality inspection before leaving the factory to ensure the quality of the appliances. Modern home appliances are generally equipped with control systems, which are generally implemented through touch screens. The quality inspection of touch screens is divided into material quality inspection and durability test inspection. Material quality inspection refers to the test of the hardness of the components of the touch screen, while the durability test refers to the test of the screen sensitivity.

[0003] The operating environment of a washing machine is rather special. Its touch screen will be stuck with water droplets during use, and the water droplets may invade the inside of the screen. Although a general washing machine screen has a certain degree of waterproofness, the probability of being stained with water droplets during use is relatively high. After being stained with water, wiping the water will also cause small scratches on the surface of the washing machine screen. The increase in small scratches will affect the sensitivity of the washing machine screen. However, in general durability experiments, only the number of sliding times of the touch screen will be tested. The damage to the touch screen caused by multiple intrusions of water droplets into the inside of the screen and the impact on the screen sensitivity after multiple wiping with a rag are not taken into account. Therefore, the accuracy of the touch screen durability experiment of most devices is low, and the factory quality of the washing machine cannot be guaranteed.

[0038] In summary, during the application of the present invention, the user first inserts the connecting pipe 49 at the input end of the water pump 48 into the water bucket, and then places the touch screen of the washing machine above the first cross bar 6. Then, the user rotates the rotating handle 13, and the rotating handle 13 drives the conversion assembly 12 to rotate, and the conversion assembly 12 drives the first bidirectional screw 7 to rotate, so that the limiting horizontal frame 8 moves inward to clamp the horizontal edge of the touch screen.

At the same time, the third drive motor 39 drives the third rotating disk 40 to rotate. The rotation of the third rotating disk 40 drives the rotation of the third connecting rod 41. Since one end of the third connecting rod 41 is rotatably connected to the eccentric shaft of the third rotating disk 40, the rotation of the third rotating disk 40 can drive the positioning slide frame 42 to move back and forth on the surface of the positioning slide block 43 through the third connecting rod 41 to simulate the left and right movement of the hand. Friction The touch screen is cleaned, and the water pump 48 sprays water on the surface of the touch screen, which can simulate the spraying of water drops on the surface of the touch screen when washing clothes. When locating the touch screen, the user can use a tool to insert the upper part of the worm rod 44 and rotate it, thereby driving the turbine 45 to rotate, and then driving the wiping rod 46 to rotate, so that the wiping rod 46 forms a certain angle with the surface of the operating table 1, so that when the user locates the touch screen, the wiping rod 46 will hinder the user's action, and at the same time, the rotation of the wiping rod 46 can make the bottom of the wiping rod 46 fit more closely with the outer surface of the touch screen;

[0040] When testing the click durability, the user first rotates the positioning screw 32 and moves the moving rod 28 to adjust the position of the touch screen rod 38 so that the bottom of the touch screen rod 38 is above the touch screen, and then the user rotates the limit nut 37 so that the touch screen rod 38 can slide up and down inside the fixing ring 33. The user adjusts the height of the touch screen rod 38 so that the bottom of the touch screen rod 38 fits the surface of the touch screen, and then the user rotates the limit nut 37 to fix the touch screen rod 38, and then starts the first drive motor 18 to drive the first rotating disk 16 to rotate, and then the first rotating disk 16 drives the first connecting rod 17 to rotate. Since one end of the first connecting rod 17 is rotatably connected to the eccentric shaft of the first rotating disk 16, the first connecting rod 17 can drive the sliding rod 15 to move up and down, thereby achieving the purpose of clicking the touch screen up and down. Multiple up and down clicks can simulate the up and down movement of a human hand to click the touch screen;

[0041] In the sliding durability test, the user starts the second driving motor 21 to drive the second rotating disk 22 to rotate, and then the second rotating disk 22 drives the second connecting rod 26 to rotate. Since one end of the second connecting rod 26 is rotatably connected to the eccentric shaft of the second rotating disk 22, the second connecting rod 26 can drive the moving rod 28 to move left and right inside the moving frame 27, thereby achieving the purpose of horizontally sliding the touch screen. Multiple left and right movements can simulate the left and right sliding of the touch screen by human hands. Since the touch screens of different washing machines are of different sizes, the user can drive the adjustment block 25 to move inside the adjustment frame 23 by rotating the adjustment screw 24, thereby achieving the purpose of adjusting the sliding range of the moving rod 28 in the moving frame 27, so that when the touch pen 38 slides, the bottom of the touch pen 38 can always be in contact with the surface of the touch screen, thereby making the sliding durability test adaptable to touch screens of different sizes.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
