[0002] Flexible display screens have the advantages of thinness, low energy consumption, and high durability. They are widely used as electronic screens such as mobile phone screens, computer screens, and full-color TV screens. Flexible display screens also have a profound impact on the application of wearable devices due to their low power consumption and bendability. Flexible display screens need to be subjected to bending tests during the production process. Based on the existing technology, it is found that the existing testing equipment has a single bending angle and a single bending position when testing the flexible display screen, which leads to great limitations in the detection, and fails to perform bending test and anti-distortion test on the flexible display screen at the same time. The flexible display screen still needs to be independently tested by corresponding testing equipment for bending test and anti-distortion test, which increases the production cost of the enterprise; In addition, flexible displays will generate heat during actual use.

[0017] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] The driving mechanism includes an electric actuator Ⅰ201, a mounting frame 202, an electric slide rail Ⅰ203 and an electric slider Ⅰ204; two electric actuators Ⅰ201 are fixedly connected to the upper part of each fixing frame 2; the telescopic parts of the electric actuator Ⅰ201 on the same fixing frame 2 are fixedly connected to the mounting frame 202; an electric slide rail Ⅰ203 is fixedly connected to each mounting frame 202; two electric sliders Ⅰ204 are slidably connected to the left electric slide rail Ⅰ203; another three electric sliders Ⅰ204 are slidably connected to the right electric slide rail Ⅰ203; each electric slider Ⅰ204 is fixedly connected to a guide tube 205.

[0020] The clamping mechanism includes a round rod 212, a fixed plate 213, an elastic member I 214, an electric actuator II 215, a connecting rod 216 and a clamping plate 217; two round rods 212 are fixedly connected to each support plate 211; the round rods 212 on the same support plate 211 are slidably connected to a fixed plate 213, and a through groove is opened in the middle of the fixed plate 213; an elastic member I 214 is sleeved on the outside of each round rod 212, and one end of the elastic member I 214 is fixedly connected to the fixed plate 213, and the other end of the elastic member I 214 is fixedly connected to the round rod 212; two electric actuators II 215 are fixedly connected to each fixed plate 213; a connecting rod 216 is fixedly connected to the telescopic part of each electric actuator II 215, and the connecting rod 216 is slidably connected to the fixed plate 213; the two connecting rods 216 on the same fixed plate 213 are fixedly connected to a clamping plate 217, and the clamping plate 217 is located in the through groove in the middle of the corresponding fixed plate 213.

[0021] The catheter 205 passes through the airbag 207 , and the catheter 205 is made of a hard material and is used to provide support for the airbag 207 .

[0022] A rubber strip is provided on one side of the clamping plate 217 away from the connecting rod 216 , so as to increase the friction between the clamping plate 217 and the flexible display screen 4 and prevent the flexible display screen 4 from being damaged.

[0023] A sponge block is arranged on one side of the through groove in the middle of the fixing plate 213 close to the rubber strip on the clamping plate 217 to provide a buffer for the flexible display screen 4 .

[0024] When testing the flexible display screen 4: pre-connect two peripheral pumps to each other with an air pipe 206, then place the flexible display screen 4 on two fixing plates 213, insert both ends of the flexible display screen 4 into the through groove in the middle of a fixing plate 213, and the end of the display screen 4 is located between the inner wall of the through groove and the clamping plate 217, then control all electric actuators II 215 to start and drive the corresponding connecting rods 216 to move, and each movement of two connecting rods 216 drives a clamping plate 217 to move, so that the clamping plate 217 moves toward the end of the display screen 4 and pushes the display screen 4 to contact the inner wall of the through groove, so that the flexible display screen 4 is clamped and limited by the two clamping plates 217, and then control all electric actuators I 201 to start, and each two electric actuators Ⅰ201 starts to drive each mounting frame 202 to move, and then drives all connected parts to move, so that all airbags 207 on the left and all airbags 207 on the right move toward each other and approach the left side and the right side of the flexible display screen 4 respectively. At the same time, the cylinder 209 moves to touch the flexible display screen 4 and squeezes the flexible display screen 4, so that the flexible display screen 4 is bent and deformed. At the same time, two external pumps are controlled to start to inflate each air pipe 206, so that the gas enters the corresponding airbag 207 through the corresponding conduit 205, so that the airbag 207 expands and squeezes the flexible display screen 4. The cylinder 209 and the airbag 207 cooperate with each other, so that the flexible display screen 4 is bent like a wave. Figure 3 As shown, in order to adapt to the bending of the flexible display screen 4, when the flexible display screen 4 is bent, the two fixed plates 213 will be driven to move along the corresponding round rod 212, and the corresponding elastic member Ⅰ214 will be compressed, so that the two fixed plates 213 will move toward each other, thereby adapting to the bending deformation of the flexible display screen 4. At this time, the bent flexible display screen 4 is inspected by an external visual detector. If the flexible display screen 4 is detected to be cracked or damaged, it means that the quality of the flexible display screen 4 is unqualified and does not meet the production standards. On the contrary, if the flexible display screen 4 is not cracked or damaged, it means that the quality of the flexible display screen 4 is qualified and meets the production standards, thereby realizing the bending test of the flexible display screen 4.

[0025] At the same time, in order to further improve the accuracy of the test, the corresponding electric slider Ⅰ204 is controlled to start moving along the corresponding electric slide rail Ⅰ203, and the movement of the electric slider Ⅰ204 drives the corresponding catheter 205 to move, and the movement of the catheter 205 drives the corresponding airbag 207 to move, thereby adjusting the position of the airbag 207, and at the same time controlling the amount of air inflation into the corresponding air tube 206 by the two external pumps, thereby changing the volume of the airbag 207, that is, adjusting the degree of squeezing of the flexible display screen 4 by the airbag 207, thereby adjusting the position of the airbag 207 and the volume of the airbag 207, and then simulating the bending of the flexible display screen 4 at different positions and to different degrees by the airbag 207, thereby making the bending test of the flexible display screen 4 more comprehensive and improving the accuracy of the bending test of the flexible display screen 4.

[0026] And to meet market demand, the flexible display screen 4 is limited by materials, production processes and usage scenarios. The flexible display screen 4 can be twisted and can withstand a large degree of twisting. However, the existing flexible display screen 4 testing equipment cannot perform bending tests and anti-twisting tests on the flexible display screen 4 at the same time. It is still necessary to use corresponding testing equipment to independently perform bending tests and anti-twisting tests on the flexible display screen 4, which increases the production cost of the enterprise. In order to test the anti-twisting performance of the flexible display screen 4, the flexible display screen 4 is in a normal unfolded state at this time and has not been bent, that is, all airbags 207 and cylinders 209 are not in contact with the flexible display screen 4. Then, the two motors 210 are controlled to start, and the output shafts of the two motors 210 rotate to drive a support plate 211 to rotate, and the two support plates 211 turn in opposite directions. The rotation of the two support plates 211 drives the corresponding round rods 212 to rotate, and the rotation of every two round rods 212 drives a fixed plate 213 to rotate, thereby driving all connected components to rotate, thereby causing the flexible display screen 4 to twist. Figure 4 As shown, at this time, the twisted flexible display screen 4 is inspected by an external visual detector. If it is detected that the flexible display screen 4 is damaged such as cracks, it means that the quality of the flexible display screen 4 is unqualified and does not meet the production standards. Otherwise, it means that the flexible display screen 4 is qualified, thereby realizing the testing of the distortion of the flexible display screen 4. At the same time, in order to further test the distortion of the flexible display screen 4, the flexible display screen 4 is twisted again when it is bent, and detected by an external visual detector, so as to know the distortion of the flexible display screen 4 when bent, and further improve the comprehensiveness of the test, so as to ensure that the quality and performance of the flexible display screen 4 meet the requirements, so as to provide users with a better user experience. At the same time, in order to test and compare flexible display screens 4 of different production batches, two flexible display screens 4 can be clamped at one time, so that the two flexible display screens 4 can be compared with each other, so as to know the quality and performance of flexible display screens 4 of different production batches, and improve the efficiency of the test.

[0027] Embodiment 2: Based on Embodiment 1, according to Figure 8-9 As shown, a protection system is also included; the protection system is connected to the fixing plate 213; the protection system includes a fixing strip 301, a high-density elastic cloth 302 and a flexible electric heating sheet 303; each fixing plate 213 is detachably connected to a fixing strip 301; all fixing strips 301 are commonly fixed with a high-density elastic cloth 302, and the high-density elastic cloth 302 is a double-layer structure; four flexible electric heating sheets 303 are embedded in the middle of the high-density elastic cloth 302.

[0028] It also includes an electric slider II 208, a cylinder 209, a movable plate 304, a top block 3041, a reinforcing rib 305 and a paddle 306; one of the driving mechanisms is connected to the electric slider II 208; the cylinder 209 is fixedly connected to the electric slider II 208; the movable plate 304 is fixedly connected to the upper surface of the cylinder 209; three top blocks 3041 are fixedly connected to the lower part of the movable plate 304; a reinforcing rib 305 is embedded in the middle part of the high-density elastic cloth 302; and a paddle 306 is fixedly connected to the upper part of the reinforcing rib 305.

[0029] The top block 3041 is configured to be in an inverted trapezoidal shape for pressing the paddle 306 .

[0030] When performing a heating test on the flexible display screen 4: Since the flexible display screen 4 will generate heat during actual use, that is, when people use it for a long time, the flexible display screen 4 will generate heat in a bent or twisted state, and the existing flexible display screen 4 testing equipment does not simulate the actual use scenario of the flexible display screen 4, resulting in an inaccurate test. After the flexible display screen 4 is placed on the two fixed plates 213, the flexible display screen 4 will press against the high-density elastic cloth 302. At this time, all the flexible electric heating plates 303 are controlled to be powered on, and then the flexible display screen 4 is heated by the flexible electric heating plates 303, thereby simulating the heating phenomenon of the flexible display screen 4 during actual use. Then, the flexible display screen 4 is bent and twisted according to the same working principle as above, thereby simulating the bending and twisting state of the flexible display screen 4 during actual use, and then the flexible display screen 4 is detected by an external visual detector, thereby improving the accuracy of the test.

[0031] At the same time, when testing two flexible display screens 4 from different production batches, the two flexible display screens 4 are placed on the fixed plate 213, and one flexible display screen 4 is located on the left side of the high-density elastic cloth 302, and the other flexible display screen 4 is located on the right side of the high-density elastic cloth 302, that is, the high-density elastic cloth 302 is sandwiched between the two flexible display screens 4. When any flexible display screen 4 breaks during the test, the high-density elastic cloth 302 is used to block the fragments generated when the flexible display screen 4 breaks, thereby preventing the fragments generated when the flexible display screen 4 breaks from splashing onto the other flexible display screen 4 and causing damage to the other flexible display screen 4.

[0032] And when the flexible display screen 4 is broken, the fragments generated by the flexible display screen 4 are easy to adhere to the high-density elastic cloth 302, thereby affecting the next use of the high-density elastic cloth 302. At this time, both flexible display screens 4 are taken out, and each fixing plate 213 is reset by the elastic force of the two elastic members I 214. The movement of the two fixing plates 213 drives each fixing bar 301 to move, so that the two fixing bars 301 move back to back, so that the high-density elastic cloth 302 remains taut. At this time, the same working principle as above is used to move the cylinder 209 close to the high-density elastic cloth 302, and the movement of the cylinder 209 drives the moving plate 304 to move, and the movement of the moving plate 304 drives all the top blocks 3041 to move, so that the top blocks 3041 touch the paddle 306 and squeeze the paddle 306. After being squeezed, the reinforcing rib 305 is driven to move, and the reinforcing rib 305 moves to stretch the high-density elastic cloth 302. When the top block 3041 moves over the paddle 306, the reinforcing rib 305 is reset by the elastic force generated by the high-density elastic cloth 302 itself, and the reinforcing rib 305 will swing back and forth, thereby driving the high-density elastic cloth 302 to swing back and forth, so that the adhering debris is separated by the reciprocating swing of the high-density elastic cloth 302, thereby preventing the debris generated by the flexible display screen 4 from adhering to the high-density elastic cloth 302, so as to facilitate the next use of the high-density elastic cloth 302, and all the fixing strips 301 are detachable structures. When the high-density elastic cloth 302 is damaged after long-term use, the two fixing strips 301 can be removed to facilitate the replacement of the high-density elastic cloth 302, making the later maintenance more convenient.

[0033] Embodiment 3: Based on Embodiment 2, according to Figure 10-12As shown, a test system is also included; the drive mechanism is connected to the test system; the test system includes a mounting plate 401, an electric slide rail II 402, an electric slider III 403, a door frame 404, an electric slide rail III 405, an electric slider IV 406, a top plate 407, a slide rod 408, a wedge block 409 and an elastic member II 410; two mounting plates 401 are connected to the mounting frame 202 on the right; each mounting plate 401 is fixedly connected to an electric slide rail II 402; each electric slide rail II 402 is slidably connected to an electric slider III 403; all electric sliders III 403 are fixedly connected to a door frame 404 ; An electric slide rail III 405 is fixedly connected to the portal frame 404; two electric sliders IV 406 are slidably connected to the electric slide rail III 405; a top plate 407 is fixedly connected to each electric slider IV 406; a plurality of slide bars 408 are slidably connected to the portal frame 404, and every three adjacent slide bars 408 form a group; a wedge block 409 is fixedly connected to each slide bar 408, and every three adjacent wedge blocks 409 form a group; an elastic member II 410 is sleeved on the outer side of each slide bar 408, and one end of the elastic member II 410 is fixedly connected to the slide bar 408, and the other end of the elastic member II 410 is fixedly connected to the portal frame 404.

[0034] It also includes a hemispherical head 4081 and a quadrangular prism 4082; one of the slide bars 408 in the same group of slide bars 408 is fixedly connected to a hemispherical head 4081, and a bump is arranged on the outer surface of the hemispherical head 4081; another slide bar 408 in the same group of slide bars 408 is fixedly connected to a quadrangular prism 4082.

[0035] The wedge block 409 located in the middle of the same set of wedge blocks 409 has a larger volume to increase the impact force.

[0036] The electric actuator I 201 and the electric actuator II 215 are electric push rods, and the elastic member I 214 and the elastic member II 410 are springs.

[0037] When the flexible display screen 4 is subjected to an impact test: the flexible display screen 4 needs to be subjected to an impact test during production to determine whether the quality of the flexible display screen 4 is qualified. During the impact test, the flexible display screen 4 will collide with the ground at different impact positions, and different impact positions and different impact forces will have different effects on the flexible display screen 4. However, the existing testing equipment does not simulate the effects of different impact positions and different impact forces on the flexible display screen 4, and has great limitations. When an unqualified flexible display screen 4 is tested, the broken fragments of the flexible display screen 4 will fly out quickly, resulting in The safety of the on-site testers is threatened. During the test, the flexible display screen 4 is in a normal unfolded state, and all the airbags 207 are in an uninflated state. Then the electric slider Ⅰ204 in the middle position on the right is controlled to start moving along the corresponding electric slide rail Ⅰ203, thereby driving all the connected parts to move, and finally the cylinder 209 is moved to the gap between the two slide bars 408 to avoid the cylinder 209 blocking the slide bar 408. Then the two electric actuators Ⅰ201 on the right are controlled to start, thereby driving all the connected parts to move, so that all the slide bars 408 are close to the flexible display screen 4, and then the two electric sliders are controlled to start. IV406 moves along the electric slide rail III405 at the same time. The two electric sliders IV406 move and each drive a top plate 407 to move. The top plate 407 moves and touches the wedge block 409, and squeezes the wedge block 409, thereby compressing the corresponding elastic member II410. The wedge block 409 moves and drives the slide bar 408 to move, and then the slide bar 408 moves and hits the flexible display screen 4, thereby realizing the impact resistance test of the flexible display screen 4. At the same time, the two electric sliders III403 are controlled to move along an electric slide rail II402 respectively. The two electric sliders III403 move and jointly drive the door frame 404 to move. The door frame 404 moves and drives All the connected parts move, thereby driving all the top plates 407 and all the slide bars 408 to move, and then using the same working principle as above to make the top plate 407 squeeze the wedge block 409, so that the slide bar 408 moves to hit the flexible display screen 4, thereby hitting different positions of the flexible display screen 4 through the movement of the slide bar 408, and through the setting of the hemispherical head 4081, the quadrangular prism 4082 and the wedge blocks 409 of different volumes, the impact force caused by the slide bar 408 on the flexible display screen 4 is different, thereby simulating the effects of different impact positions and different impact forces on the flexible display screen 4, thereby improving the accuracy of the test.

[0038] Furthermore, when the flexible display screen 4 is broken by an impact, the broken fragments of the flexible display screen 4 will fly out quickly. The high-density elastic cloth 302 can shield the fragments generated when the flexible display screen 4 is broken, thereby reducing the fragments flying everywhere and improving the safety of on-site testers. In addition, two flexible display screens 4 from different production batches can be tested at the same time, thereby simulating the impact of two flexible display screens 4 being stacked together and transported and being hit, thereby knowing the impact resistance of flexible display screens 4 from different production batches.

[0039] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
