Bending test device for flexible screen and membrane and working method thereof

Abstract

The invention discloses a bending test device for a flexible screen and a membrane and a working method thereof, relating to the technical fields of bending machines and tests of flexible devices andflexible materials. The bending test device specifically comprises a device shell, wherein a first test work station and a second test work station are respectively arranged at two sides of a drive installation groove in the middle of the device shell, the drive installation groove is internally provided with a driving system and a transmission system, which are respectively connected with two groups of multi-function fixture systems that are easy to mount and dismount, the two groups of multi-function fixture systems that are easy to mount and dismount are respectively arranged in the first test work station and the second test work station, tops of the first test work station and the second test work station are separately provided with an observation device, and the observation device is provided with a detection module. The test method for the flexible screen and the membrane prevents the tested flexible material and screen body from deforming irregularly, and bending parts of theflexible material and the screen body are U-shaped or water drop-shaped at the lower end of the baffle.

Description

technical field [0001] The invention relates to the technical field of bending equipment, in particular to a bending test equipment for flexible screens and membrane materials and a working method thereof. Background technique [0002] A flexible display is a display device made of soft materials that can be bent. Flexible displays are widely used in portable electronic devices due to their extremely thin, light, low power consumption, and bendable characteristics. Since the bending resistance of the material of the flexible display directly affects the life of the display, it is necessary to test and evaluate the bending performance of the flexible material. [0003] The traditional bending test equipment for flexible materials and screens uses several rollers with the same or different curvatures to transmit flexible materials and screens to make them bend for mechanical reliability testing. The operation process is complicated and the test cost is high; the patent applic...

Problems solved by technology

In addition, when the test board is extremely close, the spring will have a large elastic force. On the one hand, it will cause a large reaction force to the drive and transmission system, and the fixed board, making the set distance larger after long-term exercise, which will affect the test results. On the one hand, due to the change of the deformation of the spring piece, the changing force on the fixture increases the energy consumption of the equipment and the loss of the spring piece, and the spring piece is fatigued and finally broken after repeated bending, and the life is short, so it needs to be replaced frequently

[0004] In summary, there are many shortcomings in the bending test equipment of flexible materials and screens. Improve the bending test equipment to realize the compatibility test of U-shaped and drop-shaped, improve the convenience of test operation, reduce the test cost, and accurately simulate flexible materials. The bending test under the actual application conditions of the screen body has become an urgent problem to be solved
