Abstract: This paper studies the scheme of intelligent feeding system for double station conductive films with automatic azimuth recognition and deviation correction function. The combined evaluation method of comprehensive calculation evaluation-overall experience evaluation based on the method of weight coefficient and empirical fuzzy interval are proposed and adopted to evaluate and optimize the feeding system,which gives consideration to both multi index synthesis and experience evaluation of assembly effect. Through the evaluation and selection of various schemes of the feeding system, the optimal design scheme is determined. The 4-dimensional coordinate system and coordinate rotation transformation method are used to analyze the azimuth deviation and correction algorithm of the double films , and then the concept and parameter of generalized correction and generalized deviation are proposed, finally the comprehensive relationship and calculation formula between the two are deduced. The movement process of the feeding system is planned to ensure the high efficiency of the system.
