Description

Technical Field

[0002] With the rapid development of display technology, various new technologies are constantly emerging. Among them, flexible display technology has led to the development of flexible screens. The advent of flexible screens has met people's new demands for displays and has broad application prospects in wearable and portable electronic products.

[0003] Among them, the bending resistance of flexible screen is an important parameter, which is related to the screen drift and non-touch characteristics of the finished flexible display screen.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a bending test device provided in one embodiment of this application; Figure 2 for Figure 1 A disassembly diagram of the bending test equipment shown; Figure 3 for Figure 1 Another disassembled schematic diagram of the bending test equipment is shown. In this embodiment, a bending test equipment is provided to test the bending performance of the test object 8 to ensure the yield of the test object 8. The test object 8 can be a flexible display panel, which can utilize OLED display technology. Further, the flexible display panel can essentially be an OLED display panel, and this is not limited thereto.

[0040] like Figure 1 As shown, the bending test equipment specifically includes a support platform 1, a bending mechanism 2, and a support mechanism.

[0041] Among them, the support platform 1 serves as the basic carrier, which is used to place the bending mechanism 2 and the support mechanism so that the test object 8 can be bent in the future, that is, to conduct the bending test of the test object 8.

[0042] like Figure 1 As shown, the support mechanism 2 is used to support and fix the test object 8. The bending mechanism 2 includes at least one support rod 21 and a bending rod 22. The support rod 21 can be disposed on the support platform 1 and extends in a direction perpendicular to the plane of the support platform 1. In some embodiments, the support rod 21 can be a telescopic rod, which is used to drive the bending rod 22 to move up and down during the extension and retraction process, thereby realizing the up and down movement of the support mechanism 2 so that the test object 8 is bent around the outer peripheral surface of the bending rod 22.

[0043] In other embodiments, see below. Figure 6 and Figure 7 The support rod 21 can also swing relative to the support platform 1 to change the position of the bending rod 22 relative to the test object 8, thereby changing the bending position when bending the test object 8. Specifically, when the support rod 21 is set on the support platform 1, a central shaft can be set on the support platform 1, and the support rod 21 is sleeved on the central shaft and can rotate around the circumferential direction of the central shaft to realize the relative swing of the support rod 21 and the support platform 1. The specific implementation method of the swing of the support rod 21 relative to the support platform 1 can refer to the existing arrangement method between any two components that can realize relative swing, and is not limited here.

[0044] The bending rod 22 is mounted on the support rod 21 and is parallel to the surface of the test object 8. During the bending process of the test object 8, the vertical projection of the bending rod 22 on the test object 8 always overlaps with the bending area of ​​the test object 8; in other words, the orthographic projection of the bending rod 22 on the support platform 1 overlaps with the orthographic projection of the test object 8 on the support platform 1; and the support mechanism and / or bending mechanism 2 can move up and down to provide support for the test object 8 through the bending rod 22, so that the bending rod 22 bends the test object 8 during the up and down movement of the support mechanism and / or bending mechanism 2, that is, to ensure that the test object 8 can be bent around the outer circumference of the bending rod 22 during the extension and retraction of the telescopic mechanism 4.

[0045] Specifically, the support mechanism can be moved toward the side where the bending rod 22 is located, so that the bending rod 22 bends the test object 8; alternatively, the bending mechanism 2 can be moved toward the side where the test object 8 is located, so that the bending rod 22 bends the test object 8; or, the support mechanism can be moved toward the side where the bending rod 22 is located, while the bending mechanism 2 is also moved toward the side where the test object 8 is located, so that the bending rod 22 bends the test object 8.

[0046] Those skilled in the art will understand that without the bending rod 22, the test object 8, supported on the support mechanism, will rise or fall along with the support mechanism during the up-and-down movement of the support mechanism and / or the bending mechanism 2, without bending. However, this application, by providing the bending rod 22 and ensuring that the orthographic projection of the bending rod 22 on the support platform 1 overlaps with the orthographic projection of the test object 8 on the support platform 1, even if the bending rod 22 is located in the movement path of the test object 8, can thus block the movement of the portion of the test object 8 (hereinafter referred to as the bent portion) during the up-and-down movement of the support mechanism and / or the bending mechanism 2. Figure 1 As shown, since the two ends of the test object 8, which differ from the bending rod 22, are respectively fixed to the support mechanism, when the test object 8 comes into contact with the bending rod 22, as the support mechanism and / or the bending mechanism 2 continue to move up and down, the support mechanism will continue to drive the two ends of the test object 8 to continue moving towards the side where the bending rod 22 is located, or the bending rod 22 will continue to move towards the side where the test object 8 is located. At this time, the test object 8 will bend around the outer circumference of the bending rod 22. It can be understood that this bent part is the current bending position of the test object 8.

[0047] Specifically, such as Figure 1 As shown, when the test object 8 is supported on the support mechanism, the test object 8 can be located on the side of the bending rod 22 away from the support platform 1, so that the test object 8 bends towards the support platform 1 during the movement of the support mechanism toward the support platform 2 and / or the movement of the bending rod 22 away from the support platform 1. This arrangement facilitates placing or removing the test object 8 from the support mechanism. Of course, when the test object 8 is supported on the support mechanism, the test object 8 can also be located on the side of the bending rod 22 facing the support platform 1; it can be understood that in this case, the support mechanism can move in the direction away from the support platform 1 and / or the bending rod 22 can move in the direction closer to the support platform 1, so that the test object 8 bends in the direction away from the support platform 1.

[0048] In one specific embodiment, such as Figure 1 As shown, there are two support rods 21, which are spaced apart on the support platform 1. The two ends of the bent rod 22 overlap the ends of the two support rods 21 that are away from the support platform 1, and the extension direction of the bent rod 22 is parallel to the plane of the support platform 1. Specifically, the bent rod 22 is spaced apart from the support platform 1 to prevent the bent rod 22 from affecting the rotation of the turntable 3.

[0049] Of course, in other specific embodiments, the number of support rods 21 can be one or three. This application does not limit this, as long as the bending rod 22 can be supported and the bending rod 22 is spaced apart from the support platform 1.

[0050] Specifically, the bending mechanism 2 and / or the support mechanism can rotate horizontally relative to the bearing platform 1 to change the angle between the bending mechanism 2 and the support mechanism, thereby further changing the bending angle of the bending rod 22 relative to the test object 8; and / or, the bending mechanism 2 and / or the support mechanism can swing relative to the bearing platform 1 to change the position of the bending rod 22 when bending the test object 8; thus, bending performance tests can be performed on different positions of the test object 8, which can meet the diverse testing requirements of customers. The swing direction of the bending mechanism 2 and / or the support mechanism relative to the bearing platform 1 is tilted at a preset angle to the extension direction of the bending rod 22, the preset angle being greater than 0° and less than 180°; that is, these two directions are not parallel.

[0051] In some embodiments, the bending mechanism 2 and / or the support mechanism can rotate horizontally relative to the support platform 1 to change the angle between the bending mechanism 1 and the support mechanism. In this embodiment, please refer to... Figure 1 The bending test equipment also includes a turntable 3; the turntable 3 is horizontally rotatably connected to the support platform 1, and the turntable 3 can be located between two support rods 21. One of the bending mechanism 2 and the support mechanism is disposed on the turntable 3, and the other is disposed on the support platform 1. Specifically, the support mechanism can be disposed on the turntable 3, and the following embodiments of this application all use this as an example.

[0052] However, those skilled in the art will understand that in some other embodiments, the bending mechanism 2 can also be mounted on the turntable 3; in this case, the support rod 21 can be rotatably connected to the turntable 3, and the specific implementation is similar to the implementation scheme in which the support mechanism and the turntable 3 can swing relative to each other. Alternatively, the bending test device may include two turntables 3, with the bending mechanism 2 and the support mechanism respectively mounted on the two turntables 3, so that the angle between the bending mechanism 2 and the support mechanism can be changed by horizontally rotating the turntable 3, thereby changing the bending angle of the bending rod 22 relative to the test object 8.

[0053] Since the support mechanism for supporting the test object 8 is mounted on the turntable 3, the turntable 3 can drive the support mechanism to rotate horizontally along with it during horizontal rotation. This changes the angle between the test object 8 and the bending rod 22, thereby changing the relative position of the test object 8 and the bending rod 22, i.e., changing the bending position of the test object 8, to perform bending performance tests on different positions of the test object 8. Specifically, the horizontal rotation angle of the turntable 3 is greater than 0° and less than or equal to 360°.

[0054] See Figure 4 and Figure 5 , Figure 4 This is a schematic diagram showing the relative positions of the test object and the bending rod before the turntable rotates; Figure 5 This is a schematic diagram showing the relative positions of the test object and the bending rod after the turntable has rotated a certain angle. Those skilled in the art can compare this to... Figure 4 and Figure 5 It can be seen that after the turntable 3 rotates horizontally by a certain angle, the angle between the test object 8 and the bending rod 22 changes from angle α to angle β, and the position where the orthographic projections of the test object 8 and the bending rod 22 overlap on the support platform 1 changes from A to B. Therefore, this bending test equipment can change the angle between the test object 8 and the bending rod 22, and change the overlap position of the test object 8 and the bending rod 22 by rotating the turntable 3, that is, change the bending position of the test object 8, which can meet the diverse testing requirements of customers.

[0055] Specifically, turntable 3 can be a circular disc; of course, it can also be a rectangular disc, a square disc, or an irregularly shaped disc. For a specific implementation method in which turntable 3 is horizontally rotatably connected to the support platform 1, please refer to the existing connection methods of two structures rotating horizontally, such as the rotation connection method of a horizontally rotating dining table.

[0056] The support mechanism includes at least one telescopic mechanism 4. The telescopic mechanism 4 is used to move the test object 8 during the telescopic process, so that the test object 8 is bent around the outer peripheral surface of the bending rod 22.

[0057] The telescopic mechanism 4 can be mounted on the turntable 3. In one specific embodiment, the telescopic mechanism 4 can be rotatably connected to the turntable 3, meaning that the telescopic mechanism 4 can swing left and right or back and forth relative to the support platform 1 in a preset direction; for example... Figure 1 The telescopic mechanism 4 can swing left and right relative to the support platform 1 along a first direction Y. This first direction Y is inclined at a preset angle to the extension direction X of the bending rod 22. In this way, the relative position between the test object 8 and the bending rod 22 can be changed by swinging the telescopic mechanism 4, that is, the bending position of the test object 8 can be changed, and bending performance tests can be performed on different positions of the test object 8, which can meet the diverse testing requirements of customers.

[0058] Specifically, such as Figure 1 As shown, there are two telescopic mechanisms 4. Two sets of telescopic mechanisms 4 are arranged opposite each other on both sides of the bending rod 22 in a direction perpendicular to the extension direction X of the bending rod 22, and each set of telescopic mechanisms 4 includes at least one telescopic rod 41 spaced apart. Specifically, each set of telescopic mechanisms 4 includes two telescopic rods 41. Each telescopic rod 41 can extend and retract in a direction perpendicular to the plane of the turntable 3, and multiple telescopic rods 41 in the two sets of telescopic mechanisms 4 extend and retract synchronously to drive the test object 8 to move up and down, and cooperate with the bending rod 22 to bend the test object 8.

[0059] Specifically, such as Figure 2As shown, each telescopic rod 41 includes a first rod body 411 and a second rod body 412. The first rod body 411 is rotatably connected to the turntable 3, and the second rod body 412 is sleeved with the first rod body 411 and can move relative to the first rod body 411 to realize the extension and retraction of the telescopic rod 41. Specifically, the telescopic rod 41 can be a pneumatic telescopic rod, an electric telescopic rod, a spring telescopic rod, etc. The specific structure can be found in the prior art, as long as the length of the telescopic rod 41 can be variable.

[0060] Combination Figure 1 , Figure 3 , Figure 6 and Figure 7 , Figure 6 This is a schematic diagram showing the relative positions of the test object and the bending rod before the telescopic mechanism rotates. Figure 7 This is a schematic diagram showing the relative positions of the test object and the bending rod after the telescopic mechanism has rotated a certain angle; the telescopic mechanism 4 can rotate around a pivot to connect with the turntable 3. Specifically, as shown... Figure 3 As shown, a mounting bracket 5 is provided on the turntable 3, and a second rotating shaft 6 is provided on the mounting bracket 5. Each telescopic rod 41 has a rotating hole at one end near the turntable 3, that is, at the end of the first rod 411 away from the second rod 412. The first rod 411 is mounted on the second rotating shaft 6 through the rotating hole and is rotatably connected to the second rotating shaft 6. Thus, the rotation of the telescopic rod 41 around the second rotating shaft 6 drives the test object 8 carried on the telescopic mechanism 4 to move, thereby changing the position of the test object 8 relative to the bending rod 22, that is, changing the bending position of the test object 8.

[0061] Combination Figure 6 and Figure 7 After the telescopic rod 41 of each telescopic mechanism 4 rotates around the second pivot 6, the position where the orthographic projections of the test object 8 and the bending rod 22 overlap on the support platform 1 changes from C to D. Therefore, this bending test equipment can change the overlap position of the test object 8 and the bending rod 22 by rotating each telescopic rod 41, that is, change the bending position of the test object 8, which can meet the diverse testing requirements of customers.

[0062] Specifically, such as Figure 3 As shown, the extension direction of the second rotating shaft 6 can be parallel to the extension direction X of the bending rod 22; thus, the bending position of the test object 8 can be changed along the same direction Y by rotating the telescopic rod 41. Of course, the extension direction of the second rotating shaft 6 can also be tilted at a preset angle to the extension direction of the bending rod 22. The tilt angle ranges from 0° to 90°. For example, tilt angles of 10°, 20°, 30°, 40°, 50°, 60°, etc.

[0063] In a specific embodiment, the bending test device can have the turntable 3 rotatably connected to the support platform 1, and the telescopic mechanism 4 fixedly connected to the turntable 3. Alternatively, the telescopic mechanism 4 can be rotatably connected to the turntable 3, and the turntable 3 can be fixedly connected to the support platform 1. Of course, the turntable 3 can also be rotatably connected to the support platform 1, and the telescopic mechanism 4 can be rotatably connected to the turntable 3 simultaneously. This allows the rotation of the turntable 3 to change the angle between the test object 8 and the bending rod 22, as well as their relative positions. The rotation of the telescopic mechanism 4 can change the relative positions between the test object 8 and the bending rod 22, thereby enabling arbitrary changes to the measurement angle and / or bending test position of the test object 8, thus meeting diverse customer testing requirements.

[0064] In a specific embodiment, combining 1 and Figure 2 The bending test equipment also includes two sets of bearing mechanisms 7, which are respectively set at one end of the two sets of telescopic mechanisms 4 away from the turntable 3, and are used to support and fix the two ends of the object to be tested 8 for bending test.

[0065] Specifically, each support mechanism 7 includes a support plate 71, which is disposed at the end of at least one telescopic rod 41 facing away from the turntable 3, for fitting against the test object 8 to support one end of the test object 8. Specifically, the surface of the support plate 71 facing away from the turntable 3 may have adsorption holes or clamping structures. The adsorption holes can be connected to an air pump or vacuum pump to adsorb the test object 8 onto the support plate 71 or clamp it onto the support plate 71 through vacuum suction, preventing the support plate 71 from detaching from the test object 8. Of course, the support plate 71 can also fix the test object 8 onto it through magnetic adsorption, adhesive layers, clamping, snap-fitting, etc., and this application does not limit this.

[0066] Specifically, there can be one support plate 71, and the width of the support plate 71 is not less than the width of the object under test 8, to prevent local breakage or damage to the object under test 8 during the bending test. Specifically, the width of the support plate 71 matches the width of the object under test 8.

[0067] Specifically, the support plate 71 can be a telescopic plate, allowing the width of the support plate 71 to be adjusted according to the test object 8 of different widths, thereby enabling the width of the support plate 71 to match the test object 8 of different widths. Among these, [the following is a more detailed description of the specific configuration]. Figure 1 For reference, the width of the test object 8 refers to the width dimension of the test object 8 along the X direction.

[0068] In a specific embodiment, in order to prevent the telescopic mechanism 4 from damaging the test object 8 carried on the support plate 71 during the telescopic process, the support mechanism 7 is rotatably connected to the telescopic mechanism 4 so that during the telescopic process, the side surface of the support plate 71 that is in contact with the test object 8 is always parallel to the side surface of the test object 8 that is in contact with the support plate 71, thus preventing the support plate 71 from separating from the test object 8 or the test object 8 from breaking.

[0069] Specifically, in combination Figure 2 and Figure 3 The supporting mechanism 7 also includes at least one rotating component 72, which is correspondingly arranged with at least one telescopic rod 41. Each rotating component 72 is rotatably connected to the end of the telescopic rod 41 facing away from the turntable 3. The supporting plate 71 is fixed to the rotating component 72 and is rotatably connected to the telescopic rod 41 through the rotating component 72, so that the angle between the supporting plate 71 and the telescopic rod 41 can be adjusted at any time during the extension and retraction of the telescopic rod 41, ensuring that the surface of the supporting plate 71 that is in contact with the test object 8 is always parallel to the surface of the test object 8 that is in contact with the supporting plate 71. Specifically, at least one rotating component 72 is integrally formed with the corresponding supporting plate 71; of course, at least one rotating component 72 and the supporting plate 71 can also be fixedly connected by screws or other means.

[0070] In one specific embodiment, the end of the telescopic rod 41 facing away from the turntable 3 forms a groove, and the rotating component 72 is a rotating ball. The rotating ball is embedded in the groove and can rotate freely in the groove under the action of external force, that is, the rotating ball can rotate 360° in any direction in the groove.

[0071] Of course, in other specific embodiments, such as Figure 3 As shown, the end of the telescopic rod 41 away from the turntable 3 can form two opposing mounting holes 413. The rotating component 72 is the first rotating shaft, and the two ends of the first rotating shaft are respectively rotatably connected to the two mounting holes 413. The bearing plate 71 is rotatably connected to the telescopic rod 41 by the rotation of the first rotating shaft relative to the mounting holes 413.

[0072] The bending test equipment provided in this embodiment is used to perform bending tests on the test object 8. This bending test equipment includes a support platform 1, on which a bending mechanism 2 and a support mechanism are mounted. The support mechanism supports and fixes the test object 8. The bending mechanism 2 has a bending rod 22 parallel to the surface of the test object 8. The vertical projection of the bending rod 22 onto the test object 8 always overlaps with the test object 8 in the bending area. Furthermore, the support mechanism and / or the bending mechanism 2 can move up and down to bend the test object 8 using the bending rod 22. Additionally, by allowing the bending mechanism 2 and / or the support mechanism to rotate horizontally relative to the support platform 1 to change the angle between the bending mechanism 2 and the support mechanism, the bending angle of the bending rod 22 relative to the test object 8 can be further changed. And / or, the bending mechanism 2 and / or the support mechanism can swing relative to the support platform 1 to change the position of the bending rod 22 when bending the test object 8. This allows for bending performance testing of different positions of the test object 8, meeting diverse customer testing requirements.
