Bending test equipment for flexible screen and film material and working method thereof

Abstract

A bending test equipment for flexible screens and membrane materials and its working method, which relate to the technical field of bending machines, flexible devices and flexible materials, and specifically include: equipment casings; drive installation grooves in the middle of the equipment casings The two sides are the first test station and the second test station respectively. The drive and transmission system are installed in the drive installation groove. The multi-functional fixture system is respectively arranged in the first test station and the second test station, the tops of the first test station and the second test station are provided with observation devices, and a detection module is arranged on the observation and prevention device; the present invention The present invention establishes a testing method for flexible screens and membrane materials, which avoids irregular deformation of the flexible materials and screen body. The flexible material and the screen body bend at the lower end of the baffle to form a U-shaped or drop-shaped shape.

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 properties. 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 application...

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
