Description

Flexible board flexing test device and test method

The present invention relates to a flexible panel flexing test apparatus and test method; in particular, the present invention relates to a flexure test apparatus and a test method for a display panel.

With the evolution of technology, the technology of flat panel displays is also constantly improving. In order to meet the needs of the products, flat panel displays continue to study in the direction of increasing display area, narrowing the frame, thinning the thickness of the module, and improving the display effect. However, in addition to the above research directions, recently, flat panel displays have begun to develop in the direction of flexible structures.

Corresponding to the generation of the flexible display panel, it is also necessary to develop a related product verification method in order to test the flexural curvature and the number of flexing times of the product in a quantitative manner as a specification for product testing. For the test method of the flexible display panel, at present, the test method of directly bending the display panel at both ends directly by the air is adopted. As shown in FIG. 1, the conventional testing device has two clamps 2 respectively standing on the circular arc-shaped rails 3, and respectively clamping the two ends of the tested soft board 1. When the two clamps 2 are close to each other along the circular arc-shaped track 3, the test soft board 1 is driven to be bent. However, this method often causes the stress distribution on the rear panel of the display panel to be uneven due to the distribution state of the lines or components on the display panel, so that the deflection curvature of the tested display panel at each position is unpredictable. In other words, the experimental data obtained in this way tends to be more variability and less valuable.

SUMMARY OF THE INVENTION The present invention provides a soft board flex test apparatus and method that produces a deflection of a desired curvature on a flexible board.

The present invention provides a soft board flex test apparatus and method that can produce deflection at different locations of the flexible board.

The flexible panel flexing test device includes a first cylinder, a first clamping portion, a swing arm guiding unit, and a second clamping portion. The first barrel has an axially and cylindrically surrounding barrel surface; a portion of the barrel surface is formed as a barrel surface for contact with the tested soft sheet during testing to cause the soft sheet to bend around the barrel surface. When the first cylinder is cylindrical, different portions of the surface of the cylinder have the same curvature, so that the contact portions of the soft plate and the surface of the cylinder have the same curvature. The surface of the barrel has a first position; the soft sheet to be tested is in contact with the surface of the barrel from the first position. The first clamping portion is disposed on one side of the first cylinder for clamping the soft board to be tested. The swing arm type guiding unit rotates with the axis parallel to the axial direction as a rotating shaft, and can be raised or lowered with respect to the first plane defined by the first clamping portion and the first position when rotating. A second clamping portion is disposed on the swinging guiding unit, and the second clamping portion is movable toward or away from the first cylinder along the swing arm guiding unit.

The soft board flex test method includes the following steps. First, the soft board to be tested is placed on the first plane, and the first position is contacted by a surface, and the soft board under test still maintains a flat state. Then, the first clamping portion and the second clamping portion respectively clamp the two ends of the soft plate to be tested, and then rotate the swing arm guiding unit with the axis as a rotating shaft to be lifted obliquely with respect to the first plane. At this time, the soft board to be tested is bent from the first position to the surface of the cylinder.

As shown in FIG. 3 and FIG. 4, FIG. 4 is a schematic view showing an embodiment of the swing arm type guiding unit being lifted. The swing arm type guiding unit 500 rotates with the axis C parallel to the axial direction P as a rotating shaft, and the axis C Preferably, it is also located in the first plane 11 and the swing arm guiding unit 500 can be raised or lowered relative to the first plane 11 when rotated. In this embodiment, as shown in FIG. 2, the swing arm type guiding unit 500 includes an arm 510; the arms 510 may be provided separately or in pairs. In the present embodiment, the arms 510 are disposed in pairs on the outer sides of the first cylinder 100 in the axial direction P, and the axis C is disposed at the tail end of the arm 510. As shown in FIG. 3, the axis C is located below the first cylinder 100. In addition, the axis C is located on the outer side of the first cylinder 100 opposite to the first clamping portion 300, that is, the first position 111 is opposite to the outer side of the first clamping portion 300; in other words, on the first plane 11, the swing arm The guiding unit 500 and the first clamping portion 300 are in two positions of the first position 111 side. Since the angle between the portion to be lifted and the arm 510 is constantly changing during the lifting of the arm 510, the arm 510 and the soft board 10 to be tested are lifted under the above design. The change in the angle between the parts can be small to reduce the variables during the test. In addition, the axis C is preferably located on the first plane 11; in other words, when the swing arm type guiding unit 500 is laid flat, it is located on the first plane 11 to facilitate loading the tested soft board 10 before performing the test. .

The second clamping portion 700 is disposed on the swinging guiding unit 500, and the second clamping portion 700 is movable toward or away from the first cylinder 100 along the arm 510 of the swing arm guiding unit 500. As shown in FIG. 2 and FIG. 3, the second clamping portion 700 is a pair of clamping plates disposed between the two arms 510 for clamping the other end of the soft board 10 to be tested relative to the first clamping portion 700; However, in different embodiments, the second clamping portion 700 may also be composed of different types of clamping structures such as clamps, clamping bars, or suction cups. The oscillating guide unit 500 is provided with guiding means such as a slide rail for the second clamping portion 700 to be moved relative to the oscillating guiding unit 500. As shown in FIG. 3, the inner side of the arm 510 is provided with a sliding rail 530, and the end of the second clamping portion 700 can be provided with a slider or a pulley to slide with the sliding rail 530, so that the second clamping portion 700 can be Moving toward or away from the first cartridge 100. In addition, as shown in FIG. 2, the swinging guide unit 500 may be provided with a stepping motor 501 and a screw set 503 to form a driving module to control the second clamping portion 700 relative to the swinging guiding unit 500. mobile. However, in various embodiments, the drive module can also be comprised of a belt, conveyor belt, or other device.

As shown in FIG. 4, the swing arm type guiding unit 500 is tilted up relative to the first plane 11. When the swing arm type guiding unit 500 is lifted up, the tested soft board 10 will be bent corresponding to the barrel surface 110. The barrel surface 110 has a second position 112 at the other end relative to the first position 111, wherein the second position 112 is preferably a line parallel to the axial direction P, and the soft panel 10 to be tested ends from the second position 112 with the barrel surface 110 contact, so when the swing arm guiding unit 500 raises the angle differently, the second position 112 It may also change. The second clamping portion 700 and the second position 112 together define a second plane 12; in particular, the second clamping portion 700 holds the position of the tested soft board 10 and the second position 112 on the second plane 12 When the soft board 10 to be tested is lifted, the portion of the soft board 10 to be tested that is lifted in contact with the second position 112 falls on the second plane 12, and the second plane 12 is sandwiched by the first plane 11. There is an angle. The second plane 12 is a virtual planar position and is preferably tangential to the first barrel 100 at the second position 112. The tested flexible panel 10 at least partially overlaps the second plane 12 when tested, and may move along the second plane 12.

During the lifting of the swing arm guiding unit 500, the second plane 12 is also tilted up relative to the first plane 11. At the same time, the second clamping portion 700 moves along the swing arm type guiding unit 500 toward the first cylinder 100 to reduce the tension caused on the tested soft board 10 due to the angle change of the swing arm type guiding unit 500. Since in this embodiment, the tolerance and other mechanical properties of the soft plate 10 to be tested are mainly measured, if the influence of the tension during the test is too large, the variation factor of the test will be excessive, and the test will be affected. Interpretation of the results; therefore reducing the impact of tension will help to increase the accuracy of the test. In addition, when the angle at which the swing arm type guiding unit 500 is lifted relative to the first plane 11 is larger, the speed and the amplitude of the pulling force on the soft board 10 to be tested are increased in the unit time, and the second clamping is performed. The speed at which the portion 700 moves toward the first cylinder 100 can also be faster to effectively resolve unnecessary tension on the soft board 10 to be tested.

As shown in FIG. 2 and FIG. 4, the swing arm type guiding unit 500 can be controlled by another stepping motor 505 to rotate with the axis C as a rotating shaft to be lifted or lowered with respect to the first plane 11. The stepping motor 505 is preferably associated with the motor 501 for driving the second clamping portion 700 by a program or control module 400 to control the second clamping portion by the degree of lifting of the swing arm guiding unit 500. 700 mobile function. In addition, a tension monitoring unit 410 can be added to the control module 400 and connected to the second clamping portion 700 to monitor the tension received on the second clamping portion 700 and transmit the monitoring result to the control module 400. In the preferred embodiment, if the error caused by the tensile force of the second clamping portion 700 on the measured flexural strain is less than e, it is preferable to control the pulling force f provided by the second clamping portion 700 to satisfy the following equation: f<(Eh ² w)/(2eR) (Formula 1)

Where: E is the Young's modulus of the soft board 10 to be tested, h is the thickness of the soft board 10 to be tested, w is the width of the soft board 10 to be tested, and R is the radius of the first cylinder 100.

The control module 400 determines the speed of moving the second clamping portion 700 based on the monitoring result, and controls the motor 501 to perform. In different embodiments, the tension monitoring unit 410 may also be disposed to be coupled to the first clamping portion 300 to monitor the tensile force received on the first clamping portion 300, and accordingly adjust the first clamping portion 300 relative to the first cylinder 100 location and movement.

As shown in FIG. 5, in another embodiment, when the swing arm type guiding unit 500 is lifted relative to the first plane 111, the second clamping portion 700 can be parallel to the direction of the axis P as a rotating shaft, and vice versa. The swing arm type guiding unit 500 rotates. Since the angle between the swing arm type guiding unit 500 and the soft board under test 10 is also changed during the lifting process of the swing arm type guiding unit 500, the angle change can be reduced by the design. The unnecessary bending on the soft board 10 to be tested is generated, and the accuracy of the test result is further increased.

Figure 6 shows a specific embodiment of a flexible flexure testing device. As shown in FIG. 6, the first cylinder 100 is such that the bracket frame is higher than the table top of the machine table 90, so that the first plane 11 where the soft board 10 to be tested is located can be above the table top. The position of the shaft portion of the first cylinder 100 can be adjusted up and down and left and right to be used with the first cylinder 100 having different diameters under different test requirements. The swing arm type guiding unit 500 has a horizontal frame 550 whose two ends are respectively connected to the top ends of the two arms 510 to form a gate-like structure. With this design, The swing arm type guiding unit 500 can be made to have better rigidity, and the arms 510 on both sides can be driven only by providing a motor on one side. In addition, the first clamping portion 300, the second clamping portion 700, and the swing arm guiding unit 500 are all driven by the motor to drive the belt; however, as described above, in different embodiments, the motor can also be matched with the screw. Instead of a motor and belt drive combination.

7A and 7B are respectively a schematic diagram and a flow chart of a first soft board deflection test method. As shown in FIG. 7A and FIG. 7B, the soft panel 10 to be tested is first disposed between the first clamping portion 300 and the second clamping portion 700 and contacts the surface of the cylinder of the first cylinder (step 7100), that is, The tested flexible board 10 is disposed on the first plane 11 and contacts the first position 111 with a surface. At this time, the soft board 10 to be tested is preferably maintained in a flat state. Depending on the purpose of the test, the strain gauge 10 to be tested may preferably be attached with a strain gauge to obtain the required strain value after the test for subsequent analysis. Next, both ends of the soft board 10 to be tested are respectively held by the first clamping portion 300 and the second clamping portion 700 (step 7300). In the preferred embodiment, the first clamping portion 300 and the second clamping portion 700 can be respectively connected with the tension monitoring unit 410 to monitor the tension of the first clamping portion 300 and the second clamping portion 700. . In the preferred embodiment, in order to balance the tension on the flexible panel 10 to be tested, it is preferred to control the tension value provided by the second clamping portion 700 to be within the range of the foregoing formula 1.

Next, in step 7500, the second clamping portion 700 is moved to cause the soft panel 10 to be tested to be bent against the cylinder surface 110 until the first flexing test position of the soft panel 10 to be tested. In the preferred embodiment, the swing arm type guiding unit 500 is tilted up with respect to the first plane 11 with the axis C as the rotating shaft, so that the soft panel 10 to be tested is attached to the cylinder surface 110 from the first position 111. bending. When the swing arm type guiding unit 500 rotates, the second clamping portion 700 preferably moves along the swing arm type guiding unit 500. In this embodiment, the first clamping portion 300 is fixed, and the swing arm guiding unit 500 is continuously rotated to change the angle between the first plane 11 and the second plane 12 until the soft board 10 is tested. Required bending the amount. Of course, before the swing arm type guiding unit 500 is bent to bend the soft board 10 to be tested, the positions of the first clamping portion 300 and the second clamping portion 700 may be adjusted first to cause bending to be generated on the soft board 10 to be tested. The default position on the top. As shown in FIG. 7A, the free end of the swing arm type guiding unit 500 may be drawn over the first cylinder 100 while being located on the opposite side of the first cylinder 100 in the radial direction from the axis C. Finally, the characteristics to be tested of the tested soft board 10 are detected and acquired (step 7700), such as bending limit, stress strain response, tolerance or damage test. This test method simply tests the bending limit of the tested soft board 10 at a fixed point position, or the stress-strain response when a certain amount of bending is reached. In addition, it is also possible to relax and repeat the step 7500 bending to perform the tolerance or damage test. In this case, the step 7700 is not necessarily required to obtain the data on the soft board 10 to be tested, and the bending times can be matched with the softness to be tested. The test results were obtained by the damage observation of the board 10.

As shown in FIG. 7A, when the swing arm type guiding unit 500 is lifted relative to the first plane 11, the second clamping portion 700 is simultaneously moved toward the first cylinder 100; and when the swing arm type guiding unit 500 is rotated toward When the first plane 11 is lowered, the second clamping portion 700 moves in a direction away from the first cylinder 100. Since the cylindrical surface 110 has the same curvature with respect to the axial direction P when the first cylinder 100 is a cylinder, the portions of the panel 10 to be tested that are in contact with the cylinder surface 110 are also curved to have the same curvature. Figure 7C illustrates the preferred path of motion of the second clamping portion 700 in the concept of a coordinate function. As shown in FIG. 7C, when the first position 111 is taken as the origin, the coordinate function of the second clamping portion 700 is (Sx, Sy): Sx = Rsin θ + (L - Rθ) cos θ

Sy=R(1-cosθ)+(L-Rθ)sinθ

Of which: 0 θ L/R, θ is the angle of inclusion, that is, the center angle of the curved cylinder surface 110 is attached by the soft board 10 to be tested; R is the radius of the first cylinder; L is the soft board 10 to be tested from the first position 111 to the first The length of the second clamping portion 700 when it is flattened.

8A and 8B are respectively a schematic diagram and a flow chart of a second soft board deflection test method. As shown in FIGS. 8A and 8B, steps 8100 through 8500 are in principle similar to steps 7100 through 7500 of the first test method. Therefore, the main purpose of the test method is to understand the reaction of the same soft board 10 under the same bending degree at different positions, and the reaction of the soft board 10 under test when it is repeatedly subjected to bending, so the swing arm type is performed in step 8500. The lifting amount of the guiding unit 500 is different from that in step 7500, and the angle is maintained without being lowered when the preset value is reached, so that the angle between the first plane 11 and the second plane 12 is fixed. In general, the lifting amount of the swing arm guiding unit 500 in step 8500 is preferably smaller than the lifting amount of step 7500.

Next, in step 8700, the first clamping portion 300 and the second clamping portion 700 are simultaneously moved such that the first clamping portion 300 approaches the first cartridge 100 and the second clamping portion 700 moves away from the first cartridge. Specifically, this step moves the first clamping portion 300 along the first plane 11 and toward the first cylinder 100, and simultaneously moves the second clamping portion 700 along the second plane 12 away from the first cylinder 100, so that The tested soft board 10 is attached to the cylinder surface 110 to change the flexing position. Therefore, the portion of the soft sheet 10 to be tested which is pressed and bent by the first cylinder 100 is changed in accordance with the movement of the soft sheet 10 to be tested to perform bending test for different positions. During the movement of the soft board 10 to be tested, the first cylinder 100 is preferably rolled to reduce the friction with the soft board 10 to be tested; however, in different embodiments, the first cylinder 100 may also be set to no Scroll to reduce variability in the system. In a preferred embodiment, the moving speed of the first clamping portion 300 is controlled to be the same as or similar to the moving speed of the second clamping portion 700 in the tangential direction of the cylindrical surface 110 through the second clamping portion 700 to reduce A magnitude of unnecessary tension is generated on the soft board 10 to be tested. Preferably, the tangential direction of the barrel surface 110 through the second clamping portion 700 is parallel to the second plane 12. In addition, the first clamping portion 300 can also be adjusted according to the monitoring result of the tension monitoring unit 410. Or the moving speed of the second clamping portion 700.

Next, in step 8900, the first clamping portion 300 and the second clamping portion 700 are simultaneously moved to move the first clamping portion 300 away from the first cylinder and the second clamping portion 700 toward the first cylinder 100. Specifically, this step moves the first clamping portion 300 along the first plane 11 and away from the first cylinder 100, and simultaneously moves the second clamping portion 700 along the swing arm guiding unit 500 toward the first cylinder direction. The test soft board 10 is attached to the cylinder surface 110 to move. The moving direction is opposite to the moving direction in step 8700, and is preferably used to test the tolerance or damage test of the tested soft board 10 when it is repeatedly subjected to bending, or may be matched with a strain gauge to obtain a test or Stress-strain response after the test. Steps 8700 and 8900 can also be implemented repeatedly depending on the test conditions. Finally, the characteristics to be tested of the tested soft board 10 are detected and acquired (step 8950), such as bending limit, stress strain response, tolerance or damage test. This test method simply tests the bending limit of the tested soft board 10 at a fixed point position, or the stress-strain response when a certain amount of bending is reached. In addition, it is also possible to relax and repeat the step 7500 bending to perform the tolerance or damage test. In this case, the step 7700 is not necessarily required to obtain the data on the soft board 10 to be tested, and the bending times can be matched with the softness to be tested. The test results were obtained by the damage observation of the board 10.

In the embodiment shown in FIG. 9, the soft board flexing test apparatus further includes a second cylinder 200 disposed on the upper and lower sides of the first plane 11 corresponding to the first cylinder 100. In this embodiment, the axis C of the swing arm guiding unit 500 is preferably disposed on the first plane 11 , and the swing arm guiding unit 500 can selectively rotate toward the first barrel 100 as the axis C. The second cylinder 200 is rotated to be tilted up or down with respect to the first plane 11. The second cylinder 200 is disposed approximately the same as the first cylinder 100, and the relationship between the second cylinder 200 and the first clamping portion 300, the second clamping portion 700, and the swing arm guiding unit 500 is also related to the first cylinder 100. Similar to the relationship of these components. The second cylinder 200 is preferably first and first The cartridges 100 have the same diameter, and the second cartridge 200 can also have a different diameter than the first cartridge 100 only under different testing requirements. By adding the second cylinder 200, it is possible to perform a bending test on both sides of the same soft board 10 to be tested.

10A and 10B are respectively a schematic view and a flow chart of a soft board deflection test method using the test apparatus shown in FIG. As shown in FIG. 10A and FIG. 10B, the steps 1010 to 1070 are similar to the steps 8100 to 8700 in the second test method, and are not described herein again. Step 1090 is to move the second clamping portion 700 so that the soft panel 10 to be tested is bent against the second cylinder 200 until the second flexing test position of the soft panel 10 to be tested. That is, the swing arm type guiding unit 500 is rotated toward the second cylinder 200 with the axis C as the rotating shaft, so that the swing arm type guiding unit 500 is inclined downwardly with respect to the first plane 11 toward the second cylinder 200, so that the softness to be tested is made. The plate 10 is bent against the outer surface of the second cylinder 200. In other words, by the swing arm type guiding unit 500 swinging toward the second cylinder 200, one side of the test soft board 10 and the cylinder surface 110 of the first cylinder 100 are separated from the cylinder surface 110, and the soft board 10 is tested. One side is turned to be attached to the outer surface of the second cylinder 200 to bend in the opposite direction.
