TECHNICAL FIELD
[0001] The present application relates to the technical field of copper foil warping measurement, and particularly relates to a warping degree measurement device for electrolytic copper foil. BACKGROUND
[0002] The electrolytic copper foil is an important material for manufacturing the copper-clad plate, printed circuit board and lithium ion battery, and therefore the quality of the electrolytic copper foil is required to be more strict. In the quality detection of the electrode copper foil, the warping degree of the electrolytic copper foil is one of the important indexes to be considered.
[0003] Generally, the measuring device uses the reflection type image displacement sensor to measure the height of each position of the electrolytic copper foil. However, due to the light weight and thin thickness of the electrolytic copper foil, once a large force is applied to the electrolytic copper foil, the copper foil will be deformed, which makes it difficult to use a ruler to contact the copper foil for measurement. Therefore, when another instrument is used to detect the copper foil sample, the warping degree will be changed due to the movement of the copper foil sample, which is not conducive to reducing the measurement error and is not conducive to multiple measurements.
