Flexible circuit board positioning method, device and computer readable storage medium

Abstract

The invention provides a flexible circuit board positioning method, device and computer-readable storage medium, wherein the method comprises the following steps of: acquiring a digital image of a full-plate flexible circuit board on an incoming material tray; identifying all locating holes feature points in the digital image through a template matching algorithm; carrying out linear fit on the identified positioning hole characteristic points, and calculating the included angle between the fit straight line and the preset standard positioning line; identifying a local characteristic mark point of each single flexible circuit board in the digital image through a template matching algorithm; acquiring the position of a local characteristic mark point of the first flexible circuit board on the full-plate flexible circuit board according to the identification result; calculating an offset between a position of a local feature mark point of the first flexible circuit board on a full-plateflexible circuit board and a standard position of a preset first flexible circuit board; and positioning and compensating the whole flexible circuit board according to the included angle and the offset. The invention, can make the whole incoming material put into a fixture with high accuracy.

Description

technical field [0001] The invention belongs to the technical field of visual positioning algorithms, and in particular relates to a flexible circuit board positioning method, device and computer-readable storage medium. Background technique [0002] With the continuous upgrading and transformation of the manufacturing industry, the demand for automation in the production of electronic products continues to increase, especially in the fast-growing mobile phone manufacturing industry. The assembly process of the backlight film in the mobile phone is very complicated. At present, most of the flexible circuit boards in the backlight film are discharged manually; manual labor needs to tear off each single flexible circuit board in the entire flexible circuit board, and then put The single-piece flexible circuit board is placed in a specific fixture. Due to its fatigue and discontinuity, manual operation often affects the operation requirements of the production line, especially ...
