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. [00...
