Abstract

The invention provides a film parallelism control method and device in imprinting equipment, and the method comprises the steps: obtaining a deviation signal in the operation process of a film as an input variable, and judging whether the system deviation in the deviation signal is smaller than a preset deviation threshold value or not; if yes, integrating the input variables in a preset time period, obtaining a deviation control quantity according to an integration result, and eliminating deviation through the deviation control quantity; if not, defining an input and output fuzzy set, and solving a fuzzy division table of the input and output variables according to the input and output fuzzy set; determining a fuzzy relation matrix according to the fuzzy division table and a preset fuzzy calculation rule; inputting the input variable into the fuzzy relation matrix, solving the fuzzy control quantity, and eliminating the deviation through the fuzzy control quantity and the deviation control quantity. Errors continuously generated in the operation process of the thin film are calculated through the fuzzy algorithm, accumulated errors caused by control quantity calculation through a mathematical formula are effectively eliminated, and parallelism control stability is improved.

Description

technical field [0001] The present application requests protection of an imprinting equipment control technology, in particular to a method for controlling the parallelism of a thin film in an imprinting equipment. The present application also relates to a film parallelism control device in an embossing device. Background technique [0002] Three-dimensional nano-film manufacturing belongs to the field of micro-nano manufacturing technology, and micro-nano manufacturing is one of the basic technologies of the modern manufacturing industry, and it is also an important frontier technology field that has attracted much attention. [0003] In the manufacturing process of the three-dimensional nano-film, the stability of the unwinding, running and winding process of the film substrate determines the continuous embossing quality of the three-dimensional nano-film; It is the key to determine the quality of embossing. During the movement of the film, in order to ensure that the po...
