A machine visual system and method for robotic hand -setting FPC board

Abstract

The invention discloses a machine vision system and method for manipulators to pick and place FPC boards at fixed points, mainly composed of light source, lens, camera, computer and vision software. If the FPC board is placed in the bending machine, the placement accuracy cannot be guaranteed. The manipulator picks up the FPC board above the pick-up point and moves to the photographing position. The optical system composed of light source, lens and camera is fixed in the photographing position, and the FPC board is photographed from below; the photographed image is transmitted to the computer, read by the visual software, and the image is obtained through the image algorithm The position and angle of the FPC board in the middle, and then calculate the angle that the manipulator should rotate and the distance that the manipulator needs to translate after the rotation; the calculated angle and displacement are transmitted to the manipulator, and the manipulator rotates and translates the product to achieve high-precision placement. The invention has a high degree of intelligence, and through precise calculation, can effectively ensure the precision of fixed-point pick-and-place of the manipulator, and improve the efficiency of automatic production.

Description

technical field [0001] The invention belongs to the technical field of machine vision, and in particular relates to a machine vision system and method for fixed-point picking and placing of FPC boards by a manipulator. Background technique [0002] FPC boards often need to be bent into different shapes during use, and put into electronic products with high assembly density and small volume, so the requirements for bending accuracy are relatively high. As an automatic operation device that can imitate human hands and arms for suction and handling, the manipulator has the advantages of saving workers, improving efficiency, reducing costs, improving product quality, good safety, and enhancing the image of the factory. [0003] In a fast automated production line, the FPC board is placed in a carrier and moves with the conveyor belt. The manipulator picks up the product from the carrier on the conveyor belt. Since there is a gap between the product and the carrier, there is an ...
