The invention provides a diaphragm locating and fitting method and a diaphragm locating and fitting device. The diaphragm locating and fitting method comprises the steps that a first world coordinatesystem of a first camera and a second world coordinate system of a second camera are constructed; a first image and a second image are acquired through the first camera and the second camera correspondingly; the first image is an image of two opposite angles of a diaphragm; the second image is an image of two opposite angles of a substrate; coordinates of the two opposite angles of the diaphragm are obtained by making calculation on the first image in the first world coordinate system; coordinates of the two opposite angles of the substrate are obtained by making calculation on the second image in the second world coordinate system; coordinates of a first center point of the diaphragm are calculated according to the coordinates of the two opposite angles of the diaphragm, and coordinates of a second center point of the substrate are calculated according to the coordinates of the two opposite angles of the substrate; according to a deviation of the coordinates of the first center pointto coordinates of a preset first reference point and a deviation of the coordinates of the second center point to coordinates of a preset second reference point, compensation movement is carried out on a diaphragm placing platform and a substrate placing platform, so that the diaphragm fits with the substrate.
Description
technical field [0001] The invention relates to the field of lamination of equipment diaphragms, in particular to a method and device for positioning and lamination of diaphragms. Background technique [0002] With the development of electronic technology and communication technology and the improvement of people's living needs, the smart mobile device industry has shown explosive growth. The demand for mobile phones, tablet computers, etc. is huge, and the demand for the production efficiency of these electronic products has also increased. The front and rear casing diaphragms of mobile phones, tablet computers and other products have the advantages of product protection, product beauty, and product diversification, and are an indispensable part of their production. [0003] When laminating the diaphragm, the current automatic laminating equipment does not have the function of pre-positioning, which is prone to offset during the lamination process of the diaphragm, which gr...
