Problems solved by technology

Existing testing devices only support uniaxial tensile testing, and uniaxial tensile testing cannot rule out the influence of material anisotropy, and multiple tests after changing the angle not only greatly prolong the test time, but also cannot reflect the circumferential tension. Compound deformation effect during stretching

Abstract

The invention belongs to the technical field of tensile tests and particularly discloses 360-degree multidirectional synchronous stretching equipment and method for a flexible device. The equipment comprises a guide mechanism, a supporting plate, a double-slider mechanism, a lead screw nut mechanism, a driving motor and a rack. The guide mechanism comprises a large guide rod base, a small guide rod base and a guide rod connected with the large guide rod base and the small guide rod base, and the large guide rod base and the small guide rod base are installed in a center and an edge of the supporting plate respectively. One end of the double-slider mechanism is connected with the lead screw nut mechanism, and the other end is in sliding fit with the guide rod. The lead screw nut mechanism is connected with the driving motor, the lead screw nut mechanism is driven to act through the action of the driving motor, then one end, in sliding fit with the guide rod, of the double-slider mechanism is driven to move, and therefore the 360-degree multi-direction synchronous stretching of the flexible device is achieved. The method is realized by adopting the stretching equipment. According tothe invention, the multi-direction synchronous tensile test of the flexible device can be realized such that the influence of material anisotropy on the test is effectively eliminated.

Description

technical field [0001] The invention belongs to the technical field of tensile testing, and more specifically relates to a 360° multi-directional synchronous tensile equipment and method for flexible devices. Background technique [0002] Flexible electronics can be summarized as an emerging electronic technology that manufactures organic / inorganic material electronic devices on malleable plastic or thin metal substrates. National defense and other fields have broad application prospects. Since the performance of flexible electronics is equivalent to that of traditional microelectronics, and it is portable, transparent, lightweight, extendable, and easy to print in large areas quickly, many new applications have emerged, such as flexible displays, thin-film solar cells, and large-area sensors. and drives etc. [0003] The biggest feature that distinguishes flexible electronic devices from traditional microelectronics is their flexibility, which requires them to maintain go...
