The invention belongs to the technical field of image processing and provides an alignment method and device for glass and a diaphragm. The method comprises the following steps: acquiring a conversionmatrix between a camera coordinate system and a diaphragm coordinate system; separately acquiring position coordinates of the glass and the diaphragm in the camera coordinate system and converting the position coordinates into position coordinates in the diaphragm coordinate system through a conversion matrix between the camera coordinate system and the diaphragm coordinate system; calculating first translational deviation and first rotating deviation of the glass and the diaphragm according to the position coordinates of the glass and the diaphragm in the diaphragm coordinate system; if thefirst translational deviation is greater than or equal to preset translational deviation or the first rotating deviation is greater than or equal to the preset rotating deviation, inputting the firsttranslational deviation or the first rotating deviation into a PID controller to obtain second translational deviation or second rotating deviation, and controlling the alignment device to adjust theposition of the diaphragm according to the second translational deviation or the second rotating deviation. The product quality and percent of pass can be improved effectively and the production costis lowered.
Description
technical field [0001] The invention belongs to the technical field of machine vision, and in particular relates to a method and a device for aligning a glass and a diaphragm. Background technique [0002] Laminating technology has always been one of the difficulties in the processing of 3D glass for mobile phones. During the laminating process, the alignment accuracy of the glass and the diaphragm directly determines the quality of the product. The loading and transmission will cause errors in the position of the loaded materials. As a result, the alignment between the glass and the diaphragm is not accurate during the alignment process, which seriously affects the quality and yield of the product. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a method for alignment of glass and diaphragm and terminal equipment to solve the problem that the alignment accuracy of glass and diaphragm in the prior art is not high, which ...
