Abstract

The invention discloses flexographic plate pasting equipment which comprises a left objective lens and a right objective lens which are arranged at positioning marks at the two ends of a flexographic plate respectively, the left objective lens and the right objective lens are connected with image transmission bundles respectively, and the other ends, corresponding to the image transmission bundles, of the left objective lens and the right objective lens are connected with a left ocular lens and a right ocular lens respectively. Plane mirrors are arranged in the projection direction of the left eyepiece and the projection direction of the right eyepiece, the two plane mirrors are arranged in a herringbone shape at a fixed angle, and a camera is arranged at the collection position of reflected light of the two plane mirrors. According to the invention, the problems of chromatic aberration, magnification difference and random error of calibration operation in imaging caused by using double cameras to search positioning marks on two sides of the flexible layout in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of plate placement of a flexographic printing machine, and relates to a flexographic plate placement device. Background technique [0002] Existing flexographic printing equipment uses dual cameras to find positioning marks on both sides of the flexible printing plate. Due to the difference in the light transmission performance of the dual camera lenses, part of the spectrum is lost when the positioning mark is imaged, and chromatic aberration occurs in the image. At the same time, the sensitivity of the human eye to color is inconsistent, and random deviations will appear in the comparison with the calibration logo. [0003] The magnification of the dual cameras needs to be manually adjusted one by one. The consistent magnification of the dual cameras makes the operator’s adjustment process time-consuming and laborious, and is prone to fatigue, resulting in misjudgments and differences in magnification. ...
