A method, system and electronic device for controlling curved surface screen printing

Abstract

This invention provides a method, system, and electronic device for controlling curved surface screen printing. The technical solution is as follows: Based on a pre-obtained correspondence between the curved surface rotation angle and the curved surface radius, a correspondence between the curved surface rotation angle and the curved surface arc length is obtained; based on this correspondence, the maximum height of the curved surface to be printed under different rotation angles is determined; the corresponding curved surface rotation angle is determined by constraining the maximum height, thereby determining the optimal contact angle between the screen and the curved surface to be printed; the horizontal and vertical coordinates of the corresponding optimal contact point are determined based on the optimal contact angle; the four-axis positional relationship is determined based on the horizontal and vertical coordinates and the correspondence between the curved surface rotation angle and the curved surface arc length; based on the four-axis positional relationship, the difference between the horizontal coordinate of the screen and the horizontal coordinate of the optimal contact point is used as a constant control quantity to simulate the four-axis motion to obtain the four-axis motion curve, thereby controlling the four axes of the curved surface screen printing machine to perform corresponding movements. This invention solves the problems of low efficiency and low printing quality in existing curved surface screen printing control methods.
