Abstract

The invention provides a thickness detection device and method. The device includes a common electrode 100, a detection electrode 200, and a control part 300. The control part 300 is connected with the common electrode 100 for controlling the voltage information of the voltage loaded to the common electrode 100 based on the detection information of the film to be measured and generating a voltage corresponding to the voltage information, wherein the detection information is used to indicate the characteristics of the film to be measured, and the voltage information is used to indicate the characteristics of the voltage loaded to the common electrode 100; the common electrode 100 is used to load the voltage corresponding to the voltage information; the detection electrode 200 and the common electrode 100 are corresponding and spaced apart from each other, a detection channel is formed between the detection electrode 200 and the common electrode 100, and the detection electrode 200 detects the thickness of the film to be measured according to the voltage loaded to the common electrode 100. Therefore, the problem of low accuracy of thickness detection in related technology is solved, and the accuracy of thickness detection is improved.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to a thickness detection device and method. Background technique [0002] On-line continuous thickness measurement of sheet-like items, such as paper, bills, plastic films, textile items, etc., is playing an increasingly important role in the production, testing, processing, and recycling of their products. In recent years, the detection technology of film thickness through electrostatic induction between electrodes has been continuously researched and explored. For example, the patent of publication number CN210302446Y discloses a capacitive paper thickness sensor, which mainly converts the capacitance change of the capacitor into the oscillation frequency The change of the frequency is converted into a change of voltage by the frequency-voltage conversion module. The patent with the publication number CN103363887A also discloses a detection method of material thickness, which uses t...
