After long-term research on the bending detection technology of the flexible display screen shown in fig. 1, the inventor finds that when the screen body 4 to be detected is bent, it is difficult to bend the edge portion of the screen body 4 to be detected, and the bending angle of the screen body 4 to be detected in the bending process may deviate, so that the area a (see fig. 1) of the screen body 4 to be detected generates stress concentration and dead fold, and the screen body 4 to be detected is damaged. In addition, since the edge portion of the screen body 4 to be measured is difficult to fix, it is difficult to ensure the accuracy of bending detection.
In order to solve the technical problem, embodiments of the present invention provide a screen body detection apparatus and a screen body detection method, which can not only ensure accuracy of bending detection, but also avoid damage to the screen body 4 to be detected. Alternative embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1 and fig. 2, the screen detecting apparatus 100 may include a first supporting member 1, a second supporting member 2, and a rolling assembly 3. The first bearing member 1 is connected to the second bearing member 2, the first bearing surface 11 of the first bearing member 1 is connected to the second bearing surface 21 of the second bearing member 2, and the second bearing surface 21 at least includes a partial curved surface 211. The rolling assembly 3 is used for rolling the screen body 4 to be tested placed between the first bearing part 1 and the second bearing part 2, so that the part of the screen body 4 to be tested, which is located on the curved surface 211, is bent under the action of the rolling assembly 3.
It can be understood that, when the screen body 4 to be measured is extruded by the rolling component 3, a part of the screen body 4 to be measured is propped against the curved surface 211, so that the bending angle of the part of the screen body 4 to be measured, which is located on the curved surface 211, is basically fixed, and when the screen body 4 to be measured is bent under the action of the rolling component 3, the phenomenon of stress concentration and dead fold generated by the screen body 4 to be measured can be avoided, so that the damage of the screen body 4 to be measured is avoided. In addition, when bending detection is carried out, the screen body 4 to be detected is placed between the first bearing part 1 and the second bearing part 2, the first bearing part 1 can fix the screen body 4 to be detected, so that the part of the screen body 4 to be detected, which is positioned on the first bearing part 1, is restrained, but the part of the screen body to be detected, which is positioned on the second bearing part 2, is free. So, through carrying out the partial restraint to the screen body 4 that awaits measuring, can prevent to await measuring that screen body 4 receives the influence of the power except roll extrusion force at the in-process of buckling to ensure the accuracy of buckling the detection.
Further, the rolling component 3 is disposed at an end of the first carrier 1, which is far away from the second carrier 2, and is configured to move in a direction close to the second carrier 2, and roll the to-be-detected screen body 4, which is disposed between the first carrier 1 and the second carrier 2, so that the portion of the to-be-detected screen body 4, which is located on the curved surface 211, is bent better under the action of the rolling component 3.
In practical implementation, in order to ensure the overall flatness of the screen body 4 to be tested during the bending detection process, please refer to fig. 3, the rolling assembly 3 may include a rolling driving device 31, a roller sliding table 32 and a roller 33. The rolling driving device 31 is disposed at an end of the first carrier 1 away from the second carrier 2. One end of the roller slide table 32 is movably connected to the rolling drive device 31, and the other end extends in the direction of the second carrier 2. The roller 33 is rotatably connected to the other end of the roller sliding table 32, and is used for rolling the screen body 4 to be tested when the rolling driving device 31 drives the roller sliding table 32 to move towards the direction close to the second carrier 2.
In this embodiment, the rolling driving device 31 may be a driving motor, and the driving motor may move through the driving belt, and then drive the roller sliding table 32 to operate, so as to drive the roller 33 to roll the screen body 4 to be tested. So design, roller bearing 33 can be under the drive of roller bearing slip table 32 along the direction that is on a parallel with first bearing surface 11 and hold carrier 2 motion towards the second to the realization is located the continuation roll extrusion of the part of first bearing surface 11 to the screen body 4 that awaits measuring, can ensure like this that the screen body 4 that awaits measuring is at the whole planarization of the testing process of buckling, avoids the screen body 4 that awaits measuring at the testing process of buckling the fold.
In practical applications, in order to meet different bending detection standards, the bending degree of the screen body 4 to be detected may need to be adjusted, and for this purpose, please refer to fig. 4 in combination, the first supporting member 1 and the second supporting member 2 may be detachably connected. So designed, the second carrier 2 can be replaced. The curved surfaces 211 of different second carriers 2 may have different radii of curvature. For example, the radius of curvature may be selected in the range of 2.5 to 5 mm. For another example, in some usage scenarios, the radius of curvature may also be selected to be 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm, but is not limited thereto.
Accordingly, the radius of the roller 33 may also be matched to the radius of curvature of the curved surface 211. For this purpose, the roller 33 and the roller ramp 32 may also be arranged in a detachable connection. In this way, the roller 33 matched with the curvature radius of the curved surface 211 can be selected for installation, so that the opposite two surfaces of the part of the screen body to be tested 4, which is located on the curved surface 211, are uniformly stressed when the screen body to be tested 4 is subsequently extruded.
Further, the first carrier 1 and the second carrier 2 can be detachably connected in various ways, and fig. 4 shows one of the detachable connections. For example, the end of the first carrier 1 close to the second carrier 2 may be opened with a locking slot 12, and the end of the second carrier 2 close to the first carrier 1 may be opened with a locking portion 22. Like this, locate draw-in groove 12 through the card with joint portion 22 card, can realize that first carrier 1 and second carry the dismantled connection between carrier 2 to be convenient for carry out quick replacement to carrier 2 to the second under the different detection standard that buckles.
In some examples, please refer to fig. 5 in combination, the roller 33 is further provided with a pressure sensor 5 for detecting a pressure of the screen body 4 to be detected. So design, pressure sensor 5 can transmit the pressure data of the screen body 4 that awaits measuring who gathers for computer equipment, can be analyzed this pressure data by computer equipment to the analysis goes out the relevant detection data of buckling of the screen body 4 that awaits measuring.
In practical applications, the inventor also finds that, when the screen body 4 to be measured is rolled, the stress uniformity of the portion of the screen body 4 to be measured, which is located on the curved surface 211, is difficult to guarantee. To improve this technical problem, please refer to fig. 6, the buffer 6 is disposed on the area corresponding to the curved surface 211 and/or the rolling surface of the roller 33. The buffer member 6 may be made of a buffer material such as silica gel. By the design, when the curved surface 211 and the rolling surface of the roller 33 jointly press the screen body 4 to be tested, the buffer member 6 can equally divide the pressure, so that the stress uniformity of the part, located on the curved surface 211, of the screen body 4 to be tested is ensured.
In actual implementation, the buffer material 6 may be disposed in the region corresponding to the curved surface 211 alone, the buffer material 6 may be disposed in the rolling surface of the roller 33 alone, and the buffer material 6 may be disposed in the region corresponding to the curved surface 211 and the rolling surface of the roller 33 at the same time, which is not limited herein. When the buffer material 6 is disposed in the region corresponding to the curved surface 211, the buffer material 6 may be embedded in the region corresponding to the curved surface 211. It can also be understood that the outer surface of the buffer member 6 meets the surface of the second bearing surface 2 except for the region corresponding to the curved surface 211, thereby ensuring the flatness of the second bearing surface 2.
In a possible embodiment, in order to ensure the close fit of the portion of the screen body 4 to be tested located on the first supporting member 1, please refer to fig. 7, the first supporting member 1 may further be provided with an absorption structure for absorbing the portion of the screen body 4 to be tested located on the first supporting surface 11. So, can realize adsorbing fixedly the part that the screen body 4 that awaits measuring is located first loading face 11 through adsorption structure to ensure the closely laminating of the screen body 4 that awaits measuring on first loading face 11, avoid the screen body 4 that awaits measuring to receive the influence of the power except roll extrusion.
For example, a cavity (not shown) may be formed inside the first carrier 1, the first carrier surface 11 is formed with a first through hole 131 facing the panel 4 to be tested, a side surface of the first carrier 1 is formed with a second through hole 132, and the first through hole 131 and the second through hole 132 are communicated through the cavity to form the above-mentioned adsorption structure. In practical use, air in the cavity can be extracted through the second through hole 132, so that the screen body 4 to be tested can be tightly attached to the first bearing surface 11 under the adsorption action of the first through hole 131. So, when roller 33 holds the one end that carrier 2 was kept away from to the second from first carrier 1 and holds carrier 2 and move and the screen body 4 that awaits measuring of roll extrusion in the second, adsorption structure can ensure that the screen body 4 that awaits measuring can not remove to avoid the screen body 4 that awaits measuring to receive the influence of the power except the rolling force.
In a possible implementation manner, the diameter of the first through hole 131 may be 0.2-0.4 mm, and by such design, the flatness of the screen body 4 to be detected when being adsorbed can be ensured, and the problems that the screen body 4 to be detected is damaged when the screen body 4 to be detected is adsorbed due to an excessively large aperture and the adsorption force of the screen body 4 to be detected is insufficient due to an excessively small aperture are avoided.
In practical implementation, the materials of the first carrying surface 11 and the second carrying surface 21 except the curved surface 211 may be antistatic and traceless rubbers. So design, the bounce that screen body 4 that awaits measuring produced when buckling deformation and adsorbed can effectively be overcome to rubber, can ensure the planarization when screen body 4 that awaits measuring is adsorbed like this. In addition, the base and the housing of the first carrier 1 and the second carrier 2 may be made of stainless steel.
On the basis of the above, with reference to fig. 8, a screen body detection method applied to the screen body detection apparatus 100 is shown, and the method can be implemented by the following contents described in step S11 and step S12.
Step S11, the screen body 4 to be tested is placed between the first bearing member 1 and the second bearing member 2.
As shown in fig. 9, a part of the screen body 4 to be measured is located on the first supporting surface 11, and another part (edge part) is located on the second supporting surface 21.
Step S12, the rolling component 3 is controlled to move toward the direction close to the second carrier 2 to roll the screen body 4 to be tested, so that the portion of the screen body 4 to be tested located on the curved surface 211 is bent under the action of the rolling component 3.
Referring to fig. 2, fig. 10 and fig. 11, the rolling driving device 31 drives the roller sliding table 32 to move toward the direction close to the second carrier 2, the roller sliding table 32 drives the roller 33 to roll, the roller 33 starts to roll the screen body 4 to be tested from the end of the screen body 4 to be tested close to the rolling driving device 31, and when the screen body 4 to be tested rolls on the curved surface 211, the portion of the curved surface 211 of the screen body to be tested is bent. Meanwhile, the pressure sensor 5 arranged on the roller 33 can transmit the acquired pressure data to the computer equipment so as to analyze the pressure data of the computer equipment, and thus, the bending stress condition of the screen body 4 to be tested is analyzed. After the steps S11 and S12 are completed, the bent screen body 4 to be detected may be subjected to microscopic examination, and the display quality of the screen body 4 to be detected may be detected by lighting the screen body. Therefore, a data base can be provided for the subsequent manufacture of the curved screen, and the display quality of the flexible display screen under different bending conditions is ensured.
To sum up, according to the screen body detection device and the screen body detection method provided by the embodiment of the present invention, when the screen body 4 to be detected is extruded by the rolling component 3, a portion of the screen body 4 to be detected abuts against the curved surface 211, so that the bending angle of the portion of the screen body 4 to be detected located on the curved surface 211 is substantially fixed, and when the screen body 4 to be detected is bent under the action of the rolling component 3, the phenomenon of stress concentration and dead fold of the screen body 4 to be detected can be avoided, so as to avoid the damage of the screen body 4 to be detected. In addition, when detecting buckling, the screen body 4 that awaits measuring is placed in first carrier 1 and second carrier 2 between, and first carrier 1 can fix screen body 4 that awaits measuring, can prevent to await measuring screen body 4 and receive the influence of the power except the rolling force at the in-process of buckling to ensure the accuracy of buckling the detection.
