Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0028] Example 1:
[0029] To address the problems of traditional testing methods for flexible screen bending performance, where measuring devices require parameter adjustments for different screen sizes, have limited functionality requiring separate measurements, and are inconvenient to bring to exhibitions or other venues for demonstration, Embodiment 1 of this invention provides an integrated flexible screen testing machine. Figure 1 , 2 As shown, the device includes a housing 1, a bending test device 2, and a bending test device 3. Both the bending test device 2 and the bending test device 3 are fixedly installed inside the housing 1. The bending test device 2 includes a first clamping device 21 and a second clamping device 22 for fixing two opposite sides of the flexible screen. The first clamping device 21 can influence one side of the clamped flexible screen to move along a straight line on a horizontal plane. The second clamping device 22 can control one side of the flexible screen to rotate. When the first clamping device 21 and the second clamping device 22 are respectively connected to the two opposite sides of the flexible screen, in the initial position, the flexible screen is a plane. When the second clamping device 22 controls one side of the flexible screen to rotate, one end of the flexible screen clamped by the second clamping device 22 is lifted relative to the plane where the flexible screen is located in the initial position. The other end of the flexible screen clamped by the second clamping device 22... One end of the flexible screen sinks relative to the plane where the flexible screen is located in the initial position; the bending test device 3 includes a third clamping device 31 and a fourth clamping device 32 for fixing two opposite sides of the flexible screen respectively; the third clamping device 31 can affect one side of the clamped flexible screen to move along a straight line on a horizontal plane; the fourth clamping device 32 can control one side of the flexible screen to bend around the parallel line of the clamping edge; when the third clamping device 31 and the fourth clamping device 32 are respectively connected to the two opposite sides of the flexible screen, in the initial position, the flexible screen is a plane; when the fourth clamping device 32 controls one side of the flexible screen to bend, the side of the flexible screen clamped by the fourth clamping device 32 is raised as a whole relative to the plane where the flexible screen is located in the initial position; the side of the flexible screen clamped by the fourth clamping device 32 is always parallel to the side of the flexible screen clamped by the third clamping device 31.
[0030] When the flexible screen testing all-in-one machine provided in Embodiment 1 of the present invention is working, the bending performance of the flexible screen is tested by the bending testing device 2. The first clamping device 21 and the second clamping device 22 respectively clamp two opposite sides of the flexible screen. The second clamping device 22 controls one side of the flexible screen to bend relative to the side clamped by the first clamping device 21, causing one corner of the rectangular flexible screen clamped by the second clamping device 22 to bend upwards, while the adjacent corner points downwards. The side of the flexible screen clamped by the first clamping device 21 remains horizontal. During the bending process, the side of the flexible screen changes from a straight line to a curve, resulting in a stretching effect between the two opposite sides of the flexible screen clamped by the first clamping device 21 and the second clamping device 22. At this time, the first clamping device 21 will automatically move closer to the side of the flexible screen clamped by the second clamping device 22 due to this stretching effect. Therefore, it is not necessary to calculate the distance the first clamping device 21 needs to move due to the bending of the flexible screen, making it suitable for different sizes. The flexible screen is measured to complete the bending operation; similarly, the bending performance of the flexible screen is tested; the bending performance of the flexible screen is tested by the bending test device 3; the two opposite sides of the flexible screen are clamped by the third clamping device 31 and the fourth clamping device 32 respectively, so that the initial position of the flexible screen is a plane parallel to the horizontal plane. The side of the flexible screen clamped by the third clamping device 31 is controlled to be on this plane. The side clamped by the fourth clamping device 32 is controlled to move upward parallel to the side clamped by the third clamping device 31. The fourth clamping device 32 rotates the side clamped by the fourth clamping device 32 around a line parallel to the initial position plane and parallel to the side of the flexible screen clamped by the third clamping device 31, so that one side of the flexible screen bends relative to its opposite side; the third clamping device 31 will automatically move on the horizontal plane due to the movement of the fourth clamping device 32, so that no additional calculation is required to control the moving distance of the third clamping device 31. In this embodiment, bending and folding performance tests can be completed in one device when testing the performance of flexible screens. The structure of the testing device is optimized, making it more convenient to test flexible screens of different sizes and to display the tested flexible screens externally.
[0031] The tensile properties of a flexible screen are also an important parameter. In this embodiment, a tensile testing device 4 is included. The tensile testing device 4 is fixedly disposed within the housing 1. The tensile testing device 4 includes a fifth clamping device 41 and a sixth clamping device 42, which are used to fix two opposite sides of the flexible screen, respectively. The fifth clamping device 41 and the sixth clamping device 42 can fix the two opposite sides of the flexible screen to move in opposite directions. The fifth clamping device 41 and the sixth clamping device 42 fix the two opposite sides of the flexible screen, respectively. In the initial state, the flexible screen is clamped into a plane. During the test, the fifth clamping device 41 is kept stationary, while the sixth clamping device 42 moves, moving one side of the flexible screen in the opposite direction relative to the opposite side of the flexible screen, thereby detecting its tensile properties.
[0032] The curling performance is a very important parameter of flexible screens. In this embodiment, a curling test device 5 is also included. The curling test device 5 is fixedly installed inside the housing 1. The curling test device 5 includes a seventh clamping device 51 and an eighth clamping device 52 for fixing two opposite sides of the flexible screen, respectively. The seventh clamping device 51 can control one side of the clamped flexible screen to move along a straight line on a horizontal plane. The eighth clamping device 52 can control one side of the clamped flexible screen to move in the vertical direction. When the seventh clamping device 51 and the eighth clamping device 52 are respectively connected to the two opposite sides of the flexible screen, the flexible screen is in a bent state in the initial position. The two unclamped sides of the flexible screen are in the same "C" shape. However, the housing 1 should not be too complicated with too many devices. The curling test device 5 can be interchanged with the tensile test device 4. By clamping the two opposite sides of the flexible screen with the seventh clamping device 51 and the eighth clamping device 52, the seventh clamping device 51 is controlled to make one side of the flexible screen move in the horizontal direction. The eighth gripping device 52 is controlled to move one end of the flexible screen in the vertical direction. In the initial position, the two sides of the flexible screen that are not gripped are in a "C" shape. By changing the two gripped sides of the flexible screen, the radius of the "C" can be changed, thereby detecting the rolling performance of the flexible screen.
[0033] To achieve the goal of allowing the first gripping device 21 to control one side of the flexible screen to automatically move according to the internal tension of the flexible screen when the second gripping device 22 moves, in this embodiment, the first gripping device 21 includes a first pressure plate 211 and a first horizontal sliding assembly 212; the first pressure plate 211 is fixedly mounted on the sliding end of the first horizontal sliding assembly 212; the first pressure plate 211 can slide along a straight line on a horizontal plane through the first horizontal sliding assembly 212; the first pressure plate 211 includes a first upper pressure plate 2111 and a first lower pressure plate 2112; the first upper pressure plate 2111 and the first lower pressure plate 2112 are connected by two... The bolts and nuts control the distance between the first upper pressure plate 2111 and the first lower pressure plate 2112; controlling the distance between the first upper pressure plate 2111 and the first lower pressure plate 2112 allows for the loosening and clamping of the flexible screen; the first lower pressure plate 2112 is fixedly mounted on the sliding end of the first horizontal sliding assembly 212; the first clamping device 21 also includes a first restoring assembly 213; the first horizontal sliding assembly 212 includes a first guide rail 2121 and a first slider 2122; the first pressure plate 211 is fixedly mounted on the first slider 2122; the first guide rail 2121 is horizontally positioned; the first slider 2122 is mounted on the first guide rail 2121. The first slider 2122 can slide relative to the first guide rail 2121; the first recovery component 213 is connected to the first slider 2122; when the first slider 2122 is not affected by external force, the first recovery component 213 can move the first slider 2122 to a fixed position on the first guide rail 2121; the first recovery component 213 includes a first fixed pulley frame 2131, a first fixed pulley 2132 and a first counterweight 2133; the bottom of the first fixed pulley frame 2131 is fixedly connected to one end of the first guide rail 2121; the first fixed pulley 2132 is fixedly mounted on the upper part of the first fixed pulley frame 2131; the first fixed pulley 2132 can slide relative to the first guide rail 2121. The first fixed pulley frame 2131 rotates; the first counterweight 2133 is connected to the first slider 2122 via a rope; the rope connecting the first counterweight 2133 and the first slider 2122 is set on the first fixed pulley 2132; controlling the horizontal movement of the first slider 2122 on the first guide rail 2121 will transmit the power to the first counterweight 2133 through the rope and the first fixed pulley 2132, so that the first counterweight 2133 moves in the vertical direction; the weight of the first counterweight 2133 reacts to the rope, the rope gets a tension, and the rope will pull the first slider 2122 to a fixed position on the first guide rail 2121. The first recovery component 213 can pull the side of the flexible screen that was clamped by the first clamping device 21 back to the initial flattened state when the second clamping device 22 rotates back to its initial state; it controls the distance between the first upper pressure plate 2111 and the second lower pressure plate 2212 to fix one side of the flexible screen. Compared with ordinary clamping, this method has a larger clamping area, which can reduce the impact on the testing of the flexible screen due to the small contact area of the clamping part. All the pressure plates mentioned later have this effect.
[0034] The purpose of the second clamping device 22 is to rotate one side of the flexible screen being clamped, causing one side of the flexible screen to bend relative to its opposite side. In this embodiment, the second clamping device 22 includes a second pressure plate 221 for fixing the flexible screen and a second rotating assembly 222 for rotation. The second pressure plate 221 is fixedly mounted on the rotating wheel of the second rotating assembly 222.

When the side clamped by the second pressure plate 221 rotates, the center point of this side is located at the center of the rotating wheel 2221. The center of the rotating wheel 2221 is always on the plane where the flexible screen is initially located. The second pressure plate is set on the center of the rotating wheel 2221. After the rotating wheel 2221 rotates, the side of the flexible screen clamped by the second pressure plate 221 lifts one end and presses down the other end relative to the plane where the flexible screen is initially located, thereby causing one side of the flexible screen to bend relative to the side clamped by the first clamping device 21.
[0035] The structure of the third clamping device 31 is the same as that of the first clamping device 21. In this embodiment, the third clamping device 31 includes a third pressure plate 311 and a third horizontal sliding assembly 312.
