Technical Field
[0001] This invention relates to the technical field of mobile phone display screen strength testing, specifically to a multi-purpose mobile phone display screen strength testing device. Background Technology
[0002] The core objective of mobile phone display strength testing is to evaluate the performance stability and structural integrity of the display during repeated bending. In the material development stage, engineers use bending test machines to test substrates, conductive films, optical adhesives, etc. of different materials. By simulating tens of thousands or even hundreds of thousands of bending actions, they compare and analyze the fatigue resistance characteristics of various materials to provide data support for the selection of screen materials. For example, ultra-thin flexible glass (UTG) needs to pass rigorous bending tests to ensure that it can still maintain good light transmittance and scratch resistance after hundreds of thousands of folds.
[0003] Existing mobile phone bending tests mainly involve confining the phone to two folded plates and judging the strength of the phone screen by repeatedly stacking the two plates. However, this test method cannot simultaneously meet the requirements for testing different positions and bending angles of the phone screen. This results in the need for additional testing equipment for different positions and bending angles of the phone screen, which in turn increases the efficiency of the phone screen test and the use of additional testing equipment.

[0020] Please see Figures 1 to 7 The present invention provides a technical solution: a multi-purpose mobile phone display screen strength testing device, including a base plate 1, a plurality of rectangular grooves are formed on the upper surface of the base plate 1, a support plate 29 is installed in the rectangular grooves, a groove is formed on the upper surface of the support plate 29, a plurality of limiting plates 6 are arranged above the grooves, and the limiting plate 6 closest to the support plate 29 and the rectangular groove is hinged to the support plate 29. A hinge rod 30 is hinged to both sides of the limiting plate 6, and two adjacent hinge rods 30 are hinged together. The mobile phone display screen is set below the plurality of limiting plates 6, and the length of the plurality of limiting plates 6 connected together is the same as the length of the mobile phone display screen to be tested. The mobile phone display screen is inserted into the plurality of limiting plates 6, and then the limiting plates 6 can be used to limit the mobile phone display screen.
[0021] A movable groove communicating with a rectangular slot is formed on the upper surface of the base plate 1. An interceptor plate 7 is slidably connected in the movable groove. A first bearing 26 is installed on the side of the interceptor plate 7 away from the rectangular slot. A first screw 11 is installed in the first bearing 26. A first threaded cylinder 28 is threadedly connected to the annular surface of the first screw 11. The end of the first threaded cylinder 28 away from the first screw 11 passes through the movable groove. By adjusting the position of the first screw 11 in the first threaded cylinder 28, the position of the interceptor plate 7 in the movable groove can be adjusted. A blocking plate 8 is hinged to the side of the interceptor plate 7 facing the center of the rectangular slot. A section is formed on the side of the blocking plate 8 facing the interceptor plate 7. A sliding groove is provided, in which a slider 21 is slidably connected. A second bearing 25 is mounted on the upper surface of the interceptor plate 7. A second screw 24 is installed inside the second bearing 25. A second threaded cylinder 23 is threadedly connected to the end of the second screw 24 away from the second bearing 25. An adjusting plate 22 is mounted on the end of the second threaded cylinder 23 away from the second screw 24. The slider 21 is hinged to the side of the adjusting plate 22. The height of the adjusting plate 22 can be adjusted by adjusting the position of the second screw 24 in the second bearing 25. The change in the height of the adjusting plate 22 can adjust the position of the slider 21 in the sliding groove, thereby adjusting the angle between the interceptor plate 7 and the blocking plate 8.
[0022] A rotary cylinder 32 is installed inside a rectangular groove. A rotary rod 31 is rotatably connected inside the rotary cylinder 32. A torsion spring 34 is installed on the annular surface of the rotary rod 31 inside the rotary cylinder 32. The end of the torsion spring 34 away from the rotary rod 31 is installed inside the rotary cylinder 32. A pulling belt 33 is installed on the annular surface of the end of the rotary rod 31 away from the torsion spring 34. The end of the pulling belt 33 away from the rotary rod 31 is connected to the nearest limiting plate 6. The limiting plate 6 is pulled by the pulling belt 33, so that the limiting plate 6 can be restored after its position is changed.
[0023] Multiple rotating grooves are provided on both sides of the upper surface of the base plate 1. A rotating ring 4 is rotatably connected in the rotating groove. An annular groove 10 is provided on both sides of the rotating ring 4. An arc-shaped block 14 is rotatably connected in the annular groove 10. The end of the arc-shaped block 14 facing out of the annular groove 10 is installed in the rotating groove. A servo motor 2 is installed on the lower surface of the base plate 1. A rotating rod 35 is installed at the output end of the servo motor 2. Multiple gears 3 are installed on the annular surface of the rotating rod 35. A gear ring 5 is installed on the annular surface of the rotating ring 4. The gear ring 5 meshes with the gears 3. When the servo motor 2 is started, it drives the gears 3 to rotate. The rotation of the gears 3 drives the gear ring 5 to rotate. The gear ring 5 drives the rotating ring 4 to rotate.
[0024] By installing gears 3 on the annular surface of rotating ring 4, and using the meshing of gear ring 5 with gears 3, after starting servo motor 2, multiple gears 3 are driven to rotate through rotating rod 35. Gears 3 drive gear ring 5 to rotate, thereby simultaneously driving multiple rotating rings 4 to rotate, thus achieving the purpose of bending multiple mobile phone screens at the same time, saving the use of multiple drive devices.
[0025] A pusher cylinder 9 is installed inside the rotating ring 4. A pusher plate 13 is inserted into the pusher cylinder 9. The pusher plate 13 is in indirect contact with the interceptor plate 7. A squeeze cylinder 15 is installed at the end of the pusher plate 13 away from the pusher cylinder 9. A squeeze plate 17 is inserted into the squeeze cylinder 15. An inclined block 16 is installed on the side of the squeeze plate 17. Blocks 12 are installed on both sides of the blocking plate 8. The inclined block 16 is in indirect contact with the limiting plate 6 and the block 12. An elastic element, which is a spring, is installed on one side of the squeeze plate 17 inside the squeeze cylinder 15. In the normal state, the end of the elastic element away from the squeeze plate 17 is installed inside the squeeze cylinder 15. The squeeze plate 17 drives the mobile phone display screen to deflect. However, when the inclined block 16 contacts the block 12, the inclined block 16 is squeezed and moves towards the squeeze cylinder 15, driving the squeeze plate 17 to move into the squeeze cylinder 15. At this time, the squeeze plate 17 separates from the mobile phone display screen and no longer drives the mobile phone display screen to deflect.
[0026] By sliding an interception structure consisting of an interceptor plate 7, a blocking plate 8, a first bearing 26, a first screw 11, and a first threaded cylinder 28 within a movable groove, the interception structure contacts the limiting plate 6, thereby supporting the mobile phone display screen portion disposed within the multiple limiting plates 6. Simultaneously, a pressing structure consisting of a pressing cylinder 15, an inclined block 16, a pressing plate 17, and an elastic element presses the portion of the mobile phone display screen not blocked by the interception structure, thereby bending the mobile phone display screen. Since the interception structure can be adjusted in position within the movable groove, multiple mobile phone display screens disposed on the base plate 1 can be bent at different positions, thereby improving the efficiency of mobile phone display screen strength testing and reducing the use of testing equipment.
[0027] Meanwhile, by installing an adjustment structure consisting of a second bearing 25, a second screw 24, a second threaded cylinder 23, an adjustment plate 22, and a slider 21 between the interceptor plate 7 and the blocking plate 8, the angle between the blocking plate 8 and the interceptor plate 7 can be adjusted using the adjustment structure, thereby enabling the extrusion structure to drive the mobile phone display screen to bend at different angles. Combined with the interceptor plate 7, it can achieve bending of the mobile phone display screen at different positions and angles, further improving the efficiency of mobile phone display screen strength testing and reducing the use of testing equipment.
[0028] A third bearing 18 is installed at the end of the push plate 13 facing the inside of the push cylinder 9. A third screw 19 is installed inside the third bearing 18. A third threaded cylinder 20 is threadedly connected to the annular surface of the third screw 19. The third threaded cylinder 20 is installed inside the push cylinder 9, and the third threaded rod extends outside the push cylinder 9. By adjusting the position of the third screw 19 inside the third threaded cylinder 20, the position of the push plate 13 inside the push cylinder 9 is adjusted, thereby adjusting the position of the extrusion cylinder 15 and the extrusion plate 17 inside the rotating ring 4. This ensures that when the extrusion plate 17 pushes the mobile phone display screen to the blocking plate 8, the inclined block 16 is in contact with the limiting block 12. The limiting block 12 contacts and squeezes the inclined block 16, causing the inclined block 16 to drive the extrusion plate 17 to move into the extrusion cylinder 15. At this time, the extrusion plate 17 can be separated from the limiting plate 6. At this time, the limiting plate 6 drives the mobile phone display screen to the angle required for strength detection.
[0029] In summary, this multi-purpose mobile phone display strength testing device, when in use, first lifts the limiting plate 6 and places the mobile phone display under multiple limiting plates 6. Then, according to the test requirements, the position of the intercepting plate 7 in the moving groove is adjusted by the cooperation of the first screw 11 and the first threaded cylinder 28, so that the intercepting plate 7 intercepts and contacts different numbers of limiting plates 6. When the servo motor 2 is started, it drives the gear 3 to rotate. The rotation of the gear 3 drives the gear ring 5 to rotate. The rotation of the gear ring 5 drives the rotating ring 4 to rotate. When the rotating ring 4 rotates, it drives the extrusion cylinder 15 and the extrusion plate 17 to rotate through the push cylinder 9 and the push plate 13. The extrusion plate 17 causes different numbers of limiting plates 6 to deflect, that is, to bend the mobile phone display at different positions.
[0030] By adjusting the position of the second screw 24 within the second threaded cylinder 23, the height of the adjusting plate 22 is changed. This change in height of the adjusting plate 22 causes a change in the height of the adjusting block, which in turn changes the angle between the blocking plate 8 and the intercepting plate 7. The adjustment of the angle of the blocking plate 8 causes a change in the angle of the limiting block 12, ensuring that the limiting block 12 always corresponds to the position of the inclined block 16 and that the inclined block 16 remains in contact with the limiting block 12 after rotation. When the extrusion cylinder 15 and the extrusion plate 17 rotate, they cause the mobile phone display screen to bend until it moves to the inclined block 16. After contacting the blocking block 12, the squeezing plate 17 moves towards the squeezing cylinder 15 when the inclined block 16 is squeezed by the blocking block 12. At the same time, the squeezing plate 17 moves into the squeezing cylinder 15 and separates from the mobile phone display screen. At this time, the mobile phone display screen loses the obstruction of the squeezing plate 17 and returns to its original position under the pull of the pulling belt 33. The squeezing plate 17 and the squeezing cylinder 15 continue to rotate under the drive of the rotating ring 4. When the inclined block 16 separates from the blocking block 12, the elastic element pushes the squeezing plate 17 out of the squeezing cylinder 15 again, and then returns to its original position.
