DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] refer to Figure 1-4, a flexible screen bending tester includes a base 1, a control box 2, a driving member 3, a rotating device 4, a first clamping device 5, a second clamping device 6 and a height adjustment device 7. A control box 2 is provided on one side of the base 1, and a control system is provided in the control box 2. A control button can be provided on the outer surface of the control box 2, and the control button is connected to the control system to control the operation of the tester. A driving member 3 is provided in the control box 2 for providing driving force for the flexible screen bending tester. The driving member 3 can be electrically connected to the control system, and the control system can control and receive the rotation angle and number of rotations of the driving member 3. The driving member 3 can be a driving motor arranged in the control box 2, and the output shaft of the driving member 3 passes through a side wall of the control box 2 and is connected to the rotating device 4. The rotating device 4 is connected to the first clamping device 5, and a second clamping device 6 is provided on the base 1. A flexible screen 8 is connected between the first clamping device 5 and the second clamping device 6; when the driving member 3 is started, it drives the rotating device 4 to rotate, thereby driving the first clamping device 5 to rotate, thereby realizing the bending test of the flexible screen 8.
[0023] In some embodiments, the rotating device 4 includes two support blocks 41, and a rotating frame 42 is provided between the two support blocks 41. The rotating frame 42 is axially connected to the support blocks 41, and the rotating frame 42 is fixedly connected to the output shaft of the driving member 3 on the side close to the control box 2. The rotating frame 42 is connected to the first clamping device 5. When the driving member 3 is started, it drives the rotating frame 42 to rotate, thereby driving the part of the flexible screen 8 located on the first clamping device 5 to bend.
[0024] Specifically, the rotating frame 42 includes a groove plate 421, which is axially connected to the support block 41 to realize the function of rotating around the axis and is fixedly connected to the output shaft of the driving member 3. The two side walls of the groove plate 421 are provided with a first arc hole 422 and a second arc hole 423 arranged in parallel. The two side walls of the groove plate 421 are also provided with a curved block 424. The bottom of the curved block 424 is axially connected to the groove plate 421. The top of the curved block 424 is connected to a rotating pin, which can rotate along the first arc hole 422. A rotatable The rotating shaft 425, both ends of the rotating shaft 425 pass through the middle of the curved block 424, ensuring that the rotating shaft 425 can rotate smoothly; the rotating shaft 425 is connected to the first clamping device 5 with a transfer block 426, and a movable groove is provided on the top of the transfer block 426. The rotating shaft 425 passes through the movable groove to accommodate the rotating shaft 425 and allow it to move within a certain range, and the depth of the movable groove is greater than the axial diameter of the rotating shaft 425, so that the rotating shaft 425 maintains a certain degree of freedom during the bending process, ensuring that the flexible screen 8 can be evenly stressed and deformed smoothly when subjected to bending force.
[0025] When the driving member 3 is started, its output shaft drives the grooved plate 421 to rotate around the axis of the support block 41. The rotation of the grooved plate 421 is transmitted through the curved block 424 and the rotating shaft 425, and finally acts on the adapter block 426 and the first clamping device 5.
[0026] During rotation, the rotating pin at the top of the curved block 424 slides along the first arc-shaped hole 422, generating a certain swing angle. This swing, combined with the rotation of the grooved plate 421, allows the rotating shaft 425 to not only rotate about its axis but also swing within a certain range. This allows the first clamping device 5 to more flexibly adapt to the bending requirements of the flexible screen 8.
[0027] In some embodiments, the first clamping device 5 includes a positioning block 51, which is fixedly connected to the adapter block 426. The rotation of the adapter block 426 drives the positioning block 51 to rotate, thereby driving the first clamping device 5 to rotate; moving blocks 52 are symmetrically provided on both sides of the positioning block 51, and a first clamping plate 53 is provided on the moving block 52. The flexible screen 8 is clamped between the two first clamping plates 53. The two ends of the two moving blocks 52 and the two ends of the positioning block 51 are penetrated by a first connecting rod 54, and the middle of the moving block 52 and the middle of the positioning block 51 are penetrated by a first screw 55, and the first screw 55 is screwed into the moving block 52; the first screw 55 can be a double-headed screw, and the spiral directions of the threads on both sides are opposite. The first screw 55 can be rotated to drive the moving block 52 to slide along the first connecting rod 54, so that the two first clamping plates 53 are close to or away from each other, thereby changing the distance between the two first clamping plates 53, and achieving a firm clamping of the flexible screen 8.
[0028] In some embodiments, the second clamping device 6 includes a fixed slot plate 61, which is arranged on the base 1, and second connecting rods 62 are symmetrically provided at both ends of the fixed slot plate 61, and a second screw 63 is provided in the middle of the fixed slot plate 61. A slider 64 is symmetrically provided in the fixed slot plate 61, and the second connecting rod 62 and the second screw 63 both pass through the slider 64, and the second screw 63 is screwed to the slider 64. A second splint 65 is provided on the top of the slider 64, and the flexible screen 8 is clamped between the two second splints 65. By rotating the second screw 63, the slider 64 can be driven to slide on the second connecting rod 62, and the distance between the two second splints 65 can be adjusted to adapt to flexible screens 8 of different sizes.
[0029] In some embodiments, a support plate 66 is provided in the middle of the fixed groove plate 61, and the support plate 66 is arranged lower than the second clamping plate 65. The support plate 66 can increase the contact area between the flexible screen 8 and the second clamping device 6, thereby preventing the flexible screen 8 from being suspended in the air when clamped, thereby improving the stability of the flexible screen 8 being clamped.
[0030] In some embodiments, a height adjustment device 7 is provided between the second clamping device 6 and the base 1. The height adjustment device 7 includes an adjustment seat 71, which is provided on the base 1. An adjustment slot is provided on the top of the adjustment seat 71. A connecting seat 72 is provided in the adjustment slot. The connecting seat 72 can be plugged into the adjustment slot. The connecting seat 72 can be a block. The second clamping device 6 is provided on the top of the connecting seat 72. A rotatable adjustment rod 73 is provided on the adjustment seat 71. The connecting seat 72 is provided with a tooth bar. The adjustment rod 73 extends into the adjustment slot and is fixedly connected to the gear. The tooth bar engages with the gear. By rotating the adjustment rod 73 and utilizing the meshing action of the gear and the tooth bar, the connecting seat 72 can be driven to move up and down in the adjustment slot, thereby adjusting the height of the second clamping device 6 to adapt to different testing requirements.
[0031] The specific working principle is as follows:
[0032] The two ends of the flexible screen 8 are clamped on the first clamping device 5 and the second clamping device 6 respectively.
[0033] The driving member 3 is started through the control system, and the output shaft of the driving member 3 drives the rotating device 4 to rotate, thereby driving the first clamping device 5 and one end of the flexible screen 8 to perform bending movement.
[0034] During the bending process, the control system can adjust the speed and duration of the driving member 3 in real time according to preset parameters to simulate different bending scenarios.
[0035] At the same time, by adjusting the clamping force of the first clamping device 5 and the second clamping device 6 and the height of the height adjustment device 7, it is possible to ensure that the flexible screen 8 maintains a stable posture and stress state during the test.
[0036] After the test is completed, the control system automatically stops the operation of the driving member 3 and can output the test results as needed for subsequent analysis.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents.
