Description

Technical Field

[0001] The present invention belongs to the field of touch display screens, and particularly relates to a testing machine for touch display screens. Background Art

[0002] Flexible display screens have the advantages of being thin, low in energy consumption, and high in durability, and are widely used as electronic screens such as mobile phone screens, computer display 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 bendable characteristics. During the production process of flexible display screens, bending tests need to be carried out on them;

[0003] Based on the prior art, it is found that when the existing testing equipment tests flexible display screens, there are single bending angles and single bending positions, resulting in great limitations in detection. Moreover, the flexible display screens cannot be simultaneously subjected to bending tests and anti-twisting tests, and corresponding testing equipment still needs to be used independently to perform bending tests and anti-twisting tests on flexible display screens, increasing the production costs of enterprises;

[0004] In addition, flexible display screens will heat up during actual use, that is, after people use them for a long time, flexible display screens will heat up in a bent or twisted state. However, the existing flexible display screen testing equipment does not simulate the actual use scenarios of flexible display screens, resulting in inaccurate tests. Summary of the Invention

[0016] The advantages and positive effects of the present invention are as follows:

[0017] (1) The flexible display screen is clamped and limited by two clamping plates, and all airbags are inflated, so that all airbags expand and squeeze the flexible display screen, thereby causing the flexible display screen to bend in a wave-like shape, and then the bent flexible display screen is detected, so as to realize the bending test of the flexible display screen;

[0018] (2) By adjusting the position and volume of the airbag, different positions and degrees of bending of the airbag on the flexible display screen are simulated, so that the bending test of the flexible display screen is more comprehensive, and the accuracy of the bending test of the flexible display screen is improved;

[0019] (3) By rotating two fixed plates in opposite directions, the flexible display screen is twisted, and then the twisted flexible display screen is detected, so as to test the twist degree of the flexible display screen.

[0021] (5) The fragments generated when the flexible display screen breaks are blocked by a high-density elastic cloth, so as to avoid the problem that the fragments generated when the flexible display screen breaks splash onto another flexible display screen and cause damage to the other flexible display screen. The adhered fragments are separated by the reciprocating swing of the high-density elastic cloth, so as to avoid the fragments generated by the flexible display screen adhering to the high-density elastic cloth, facilitating the next use of the high-density elastic cloth;

[0022] (6) The flexible display screen is impacted by moving a slide bar to realize the drop resistance test of the flexible display screen. The slide bar moves to impact different positions of the flexible display screen.

Detailed implementation manners

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Embodiment 1: A testing machine for a touch display screen, according to Figures 1-7As shown in the figure, it includes a chassis 1, a fixed frame 2, and a support frame 3; two fixed frames 2 are fixedly connected to the upper surface of the chassis 1; two support frames 3 are fixedly connected to the middle of the upper surface of the chassis 1;

[0038] It further includes a driving mechanism, a conduit 205, a trachea 206, an airbag 207, a motor 210, a support plate 211, and a clamping mechanism; a driving mechanism is connected to each fixed frame 2, and the two driving mechanisms are arranged oppositely; two conduits 205 are connected to each driving mechanism; the driving mechanism is used to drive the conduit 205 to move; two conduits 205 connected to the same driving mechanism are fixedly connected and communicated with a trachea 206, and a joint is arranged on the trachea 206; an airbag 207 is installed outside each conduit 205; a motor 210 is installed on each support frame 3; a support plate 211 is fixedly connected to the output shaft of each motor 210; a clamping mechanism for clamping and limiting the flexible display screen 4 is connected to each support plate 211.

[0039] The driving mechanism includes an electric actuator I 201, a mounting frame 202, an electric slide rail I 203, and an electric slider I 204; two electric actuators I 201 are fixedly connected to the upper part of each fixed frame 2; the telescopic parts of the electric actuators I 201 on the same fixed frame 2 are fixedly connected to the mounting frame 202; an electric slide rail I 203 is fixedly connected to each mounting frame 2; two electric sliders I 204 are slidably connected to the left electric slide rail I 203; another three electric sliders I 204 are slidably connected to the right electric slide rail I 203; each electric slider I 204 is fixedly connected to a conduit 205.

[0040] The clamping mechanism includes a round rod 212, a fixing 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; a fixing plate 213 is slidably connected to the round rods 212 on the same support plate 211, and a through groove is formed in the middle of the fixing plate 213; an elastic member I 214 is sleeved outside each round rod 212, and one end of the elastic member I 214 is fixedly connected to the fixing 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 fixing 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 fixing plate 213; two connecting rods 216 on the same fixing 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 fixing plate 213.

[0041] The conduit 205 penetrates through the airbag 207, and the conduit 205 is made of a hard material and is used to provide support for the airbag 207.

[0042] A rubber strip is provided on the side of the splint 217 away from the connecting rod 216, which is used to increase the friction between the splint 217 and the flexible display screen 4 and prevent damage to the flexible display screen 4.

[0043] A sponge block is provided on the side of the through groove in the middle of the fixed plate 213 close to the rubber strip on the splint 217, which is used to provide buffering for the flexible display screen 4.

[0044] When testing the flexible display screen 4: First, each of the two peripheral pump machines is connected to a trachea 206, and then the flexible display screen 4 is placed on the two fixed plates 213, so that both ends of the flexible display screen 4 are inserted into the through grooves in the middle of one fixed plate 213 respectively, and the end of the display screen 4 is located between the inner wall surface of the through groove and the splint 217. Then, control all the electric actuators II 215 to start and drive the corresponding connecting rods 216 to move. Each two connecting rods 216 move to drive one splint 217 to move respectively, so that the splint 217 moves towards the end of the display screen 4 and pushes the display screen 4 to contact the inner wall surface of the through groove, thereby clamping and limiting the flexible display screen 4 through the two splints 217. Then, control all the electric actuators I 201 to start. Each two electric actuators I 201 start to drive one mounting bracket 202 to move respectively, and then drive all the connected components to move. As a result, all the air bags 207 on the left and all the air bags 207 on the right move towards 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 and touches the flexible display screen 4, causing extrusion on the flexible display screen 4, so that the flexible display screen 4 undergoes a bending deformation. At the same time, control the two peripheral pump machines to start and inflate each into one trachea 206 respectively, so that the gas enters the corresponding air bag 207 through the corresponding conduit 205, causing the air bag 207 to expand and exert extrusion on the flexible display screen 4. The cylinder 209 and the air bag 207 cooperate together, so that the flexible display screen 4 undergoes a bending similar to a wave shape, as Figure 3 shown. At the same time, to adapt to the bending of the flexible display screen 4, when the flexible display screen 4 bends, it will drive the two fixed plates 213 to move along the corresponding round rods 212 and compress the corresponding elastic members I 214, so that the two fixed plates 213 move towards each other, thereby adapting to the bending deformation of the flexible display screen 4. At this time, use the peripheral vision detector to detect the bent flexible display screen 4. If it is detected that the flexible display screen 4 is damaged such as cracked, it means that the quality of the flexible display screen 4 is unqualified and does not meet the production standard. On the contrary, if the flexible display screen 4 does not show damage such as cracked, it means that the quality of the flexible display screen 4 is qualified and meets the production standard, thus realizing the bending test of the flexible display screen 4.

[0045] Meanwhile, to further improve the accuracy of the test, the corresponding electric slider I 204 is controlled to start moving along the corresponding electric slide rail I 203. The movement of the electric slider I 204 drives the corresponding conduit 205 to move, and the movement of the conduit 205 drives the corresponding airbag 207 to move, thereby adjusting the position of the airbag 207. At the same time, two peripheral pump machines are controlled to inflate the corresponding trachea 206, thereby changing the volume of the airbag 207, that is, adjusting the extrusion degree of the airbag 207 on the flexible display screen 4. Thus, by adjusting the position and volume of the airbag 207, different positions and degrees of bending of the airbag 207 on the flexible display screen 4 are simulated, 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.

[0046] And to meet market demand, due to the limitations of materials, production processes, and usage scenarios, the flexible display screen 4 can be twisted and can withstand a large degree of twist. However, existing testing equipment for flexible display screens 4 cannot simultaneously perform bending tests and anti-twist tests on the flexible display screen 4. It is still necessary to independently perform bending tests and anti-twist tests on the flexible display screen 4 through corresponding testing equipment, resulting in an increase in the production cost of enterprises. To test the anti-twist performance of the flexible display screen 4, at this time, the flexible display screen 4 is in a normal unfolded state and not bent, that is, all airbags 207 and cylinders 209 do not contact the flexible display screen 4. Then, two motors 210 are controlled to start. The output shafts of the two motors 210 rotate to drive a support plate 211 to rotate respectively, and the rotation directions of the two support plates 211 are opposite. The rotation of the two support plates 211 drives the corresponding round rods 212 to rotate respectively, and the rotation of every two round rods 212 drives a fixing plate 213 to rotate respectively, thereby driving all connected components to rotate, and further twisting the flexible display screen 4. As Figure 4 shown, at this time, the twisted flexible display screen 4 is detected by an external visual detector. If it is detected that the flexible display screen 4 is damaged such as cracked, it indicates that the quality of the flexible display screen 4 is unqualified and does not meet the production standard. Otherwise, it indicates that the flexible display screen 4 is qualified, thus realizing the test of the twist degree of the flexible display screen 4. At the same time, to further test the twist degree of the flexible display screen 4, the flexible display screen 4 is twisted again in a bent state and detected by an external visual detector, so as to know the twist degree of the flexible display screen 4 in the bent state, further improving the comprehensiveness of the test, ensuring that the quality and performance of the flexible display screen 4 meet the requirements, and facilitating a better user experience. At the same time, to test and compare flexible display screens 4 of different production batches, two flexible display screens 4 can be clamped at one time, making the two flexible display screens 4 contrast with each other, so as to know the quality and performance of flexible display screens 4 of different production batches and improve the test efficiency.

[0047] Embodiment 2: On the basis of Embodiment 1, according to Figures 8-9 As shown, it further includes a protection system; a 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; a fixing strip 301 is detachably connected to each fixing plate 213; a high-density elastic cloth 302 is fixedly connected to all the fixing strips 301 together, and the high-density elastic cloth 302 is of a double-layer structure; four flexible electric heating sheets 303 are embedded in the middle of the high-density elastic cloth 302.

[0048] It further includes an electric slider II 208, a cylinder 209, a moving plate 304, a top block 3041, a reinforcing rib 305, and a dial 306; an electric slider II 208 is connected to one of the driving mechanisms; a cylinder 209 is fixedly connected to the electric slider II 208; a moving 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 moving plate 304; a reinforcing rib 305 is embedded in the middle of the high-density elastic cloth 302; a dial 306 is fixedly connected to the upper part of the reinforcing rib 305.

[0049] The top block 3041 is set in an inverted trapezoid shape for squeezing the dial 306.

[0050] 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, after people use it for a long time, the flexible display screen 4 will generate heat in a bent or twisted state. However, the existing flexible display screen 4 test equipment does not simulate the actual use scenario of the flexible display screen 4, resulting in inaccurate testing. After the flexible display screen 4 is placed on the two fixing plates 213, the flexible display screen 4 will abut against the high-density elastic cloth 302. At this time, control all the flexible electric heating sheets 303 to be energized and operate, and then heat the flexible display screen 4 through the flexible electric heating sheets 303, so as to simulate the phenomenon of heat generation of the flexible display screen 4 during actual use. Then, perform bending and twisting tests on the flexible display screen 4 based on the same working principle as above, so as to simulate the bending and twisting states of the flexible display screen 4 during actual use, and then detect the flexible display screen 4 through an external visual detector, thereby improving the accuracy of the test.

[0051] When testing two flexible display screens 4 of different production batches, the two flexible display screens 4 are both placed on the fixing 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 one of the flexible display screens 4 breaks during the test, the high-density elastic cloth 302 blocks the fragments generated when the flexible display screen 4 breaks, thereby avoiding the problem that the fragments generated when the flexible display screen 4 breaks splash onto the other flexible display screen 4 and cause damage to the other flexible display screen 4.

[0052] And when the flexible display screen 4 breaks, the fragments generated by the flexible display screen 4 are easily adhered to the high-density elastic cloth 302, which in turn affects 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 two elastic members I 214. The movement of the two fixing plates 213 drives the movement of one fixing strip 301 each, so that the two fixing strips 301 move away from each other, and then the high-density elastic cloth 302 is kept in a taut state. At this time, the cylinder 209 is moved closer to the high-density elastic cloth 302 according to the same working principle as above. The movement of the cylinder 209 drives the movement of the moving plate 304, and the movement of the moving plate 304 drives the movement of all the top blocks 3041, so that the top blocks 3041 touch the dial 306 and squeeze the dial 306. After being squeezed, the dial 306 drives the movement of the reinforcing rib 305, and the movement of the reinforcing rib 305 stretches the high-density elastic cloth 302. When the top block 3041 moves past the dial 306, the reinforcing rib 305 moves back to its original position 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 adhered fragments are separated by the reciprocating swing of the high-density elastic cloth 302, thereby avoiding the fragments generated by the flexible display screen 4 from adhering to the high-density elastic cloth 302, facilitating the next use of the high-density elastic cloth 302, and all the fixing strips 301 are of detachable structure. 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.

[0053] Embodiment 3: On the basis of Embodiment 2, according to Figures 10-12As shown in the figure, it further includes a test system; a test system is connected to the driving mechanism; the test system includes a mounting plate 401, an electric slide rail II 402, an electric slider III 403, a gantry 404, an electric slide rail III 405, an electric slider IV 406, a top plate 407, a slide bar 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; an electric slide rail II 402 is fixedly connected to each mounting plate 401; an electric slider III 403 is slidably connected to each electric slide rail II 402; all the electric sliders III 403 are commonly fixedly connected to a gantry 404; an electric slide rail III 405 is fixedly connected to the gantry 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 gantry 404, and every three adjacent slide bars 408 in the front and back are taken as a group; a wedge block 409 is fixedly connected to each slide bar 408, and every three adjacent wedge blocks 409 in the front and back are taken as a group; an elastic member II 410 is sleeved outside 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 gantry 404.

[0054] It further includes a hemispherical head 4081 and a quadrangular prism 4082; a hemispherical head 4081 is fixedly connected to one of the slide bars 408 in the same group of slide bars 408, and convex blocks are arranged on the outer surface of the hemispherical head 4081; a quadrangular prism 4082 is fixedly connected to another slide bar 408 in the same group of slide bars 408.

[0055] Among the wedge blocks 409 in the same group, the volume of the wedge block 409 in the middle position is larger, which is used to increase the impact force.

[0056] 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.

[0057] When performing an impact resistance test on the flexible display screen 4: During the production of the flexible display screen 4, an impact resistance test needs to be carried out on it to determine whether the quality of the flexible display screen 4 is qualified. During the impact resistance test, the flexible display screen 4 will collide with the ground, and the impact positions are different. The impacts of different impact positions and different impact forces on the flexible display screen 4 are also different. However, the existing test equipment does not simulate the impacts of different impact positions and different impact forces on the flexible display screen 4, which has great limitations. And when testing a non-conforming flexible display screen 4, the broken fragments of the flexible display screen 4 will fly out quickly, threatening the safety of on-site testers. During the test, the flexible display screen 4 is in a normal unfolded state, and all airbags 207 are in an uninflated state. Then, control the electric slider I 204 at the middle position on the right to start moving along the corresponding electric rail I 203, thereby driving all the connected components to move, and finally moving the cylinder 209 into the gap between the two slide bars 408 to prevent the cylinder 209 from blocking the slide bars 408. Then, control the two electric actuators I 201 on the right to start, thereby driving all the connected components to move, and further making all the slide bars 408 approach the flexible display screen 4. Next, control the two electric sliders IV 406 to move along the electric rail III 405 at the same time. The movement of the two electric sliders IV 406 each drives a top plate 407 to move. The movement of the top plate 407 touches the wedge block 409 and exerts pressure on the wedge block 409, thereby compressing the corresponding elastic member II 410. The movement of the wedge block 409 drives the slide bar 408 to move, and then the slide bar 408 moves to impact the flexible display screen 4, thus realizing the impact resistance test on the flexible display screen 4. At the same time, control the two electric sliders III 403 to move along one electric rail II 402 each. The movement of the two electric sliders III 403 together drives the gantry 404 to move. The movement of the gantry 404 drives all the connected components to move, and further drives all the top plates 407 and all the slide bars 408 to move. Then, using the same working principle as above, make the top plate 407 press the wedge block 409, so that the slide bar 408 moves to impact the flexible display screen 4, and thus impact different positions of the flexible display screen 4 through the movement of the slide bar 408. And through the settings of the hemispherical head 4081, the quadrangular prism 4082 and the wedge blocks 409 with different volumes, the impact forces exerted by the slide bar 408 on the flexible display screen 4 are different, thus simulating the impacts of different impact positions and different impact forces on the flexible display screen 4, and improving the accuracy of the test.

[0058] And when the flexible display screen 4 is broken by impact, the broken fragments of the flexible display screen 4 will fly out quickly. The high-density elastic cloth 302 is used to block the fragments generated when the flexible display screen 4 is broken, so as to reduce the fragments flying everywhere and improve the safety of on-site testers. At the same time, two flexible display screens 4 of different production batches can be tested simultaneously, so as to simulate the influence generated after the two flexible display screens 4 are stacked and carried and impacted, and thus know the impact resistance of the flexible display screens 4 of different production batches.

[0059] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
