Copper foil tension testing device

Abstract

The invention discloses a copper foil tension testing device which comprises a bottom plate, a lifting plate, a vertical frame, two airbag clamps and an overload protection assembly, and is characterized in that the vertical frame is arranged on the bottom plate, a vertical lead screw is arranged on the vertical frame, and the lifting plate is in threaded fit with the lead screw; a mounting frameis arranged on the bottom plate, and the overload protection assembly is arranged on the lower end face of the lifting plate. Each airbag clamp comprises a support, a first air bag, a second air bag and an inflation device, the first air bag and the second air bag are oppositely arranged on the support, the inflation device is used for inflating the first air bag and the second air bag, a first flexible clamping piece is arranged on the side face, close to the second air bag, of the first air bag, a second flexible clamping piece is arranged on the side face, close to the first air bag, the first flexible clamping piece is provided with a plurality of protruding edges, and grooves matched with the protruding edges are formed in the positions, corresponding to the protruding edges, of the second flexible clamping piece. The soft clamping of the copper foil is achieved through the airbag clamps, the copper foil cannot be scratched or crushed, and the accuracy of a tension test result isguaranteed.

Description

technical field [0001] The invention relates to the technical field of copper foil tensile testing devices, in particular to a copper foil tensile testing device. Background technique [0002] In the production process of copper foil, it is necessary to use a tensile test device to perform a tensile test on the copper foil sample to analyze its tensile strength. [0003] However, because the copper foil is relatively thin and soft, the traditional tensile test device usually uses a hard clamp to fix the copper foil and then perform the tensile test. During the clamping process, the copper foil may be scratched or crushed, resulting in the test The result is not accurate. Contents of the invention [0004] The problem to be solved by the present invention is to provide a copper foil tensile test device, which can softly clamp the copper foil through the airbag clamp, without scratching or crushing the copper foil, and ensure the accuracy of the tensile test results.
