The invention relates to a method for guiding a robot to suck buzzers for dust removal. The method comprises the following steps that S1, manually placing the buzzers in a material suction disc at will; S2, enabling the robot to start to operate and establish connection with a camera; S3, enabling the robot to send out a trigger signal to trigger the camera to photograph; S4, after an image is captured, carrying out corresponding image algorithm processing, judging whether a buzzer meeting the capturing conditions exists or not, and if the material meeting the conditions exists, sending the coordinates of the material to the robot; and S5, enabling the robot to grab four buzzer materials at a time, then enabling the robot to grab the materials, firstly adhering the materials to an adhesivetape for one time and then sucking the materials by an air suction machine for one time so as to carry out two times of dust removal, placing the materials into a dust removal finishing disc after dust removal, and repeatedly executing the actions after the step S3. According to the method for guiding the robot to suck the buzzers for dust removal provided by the invention, materials meeting theconditions are grabbed through automatic recognition of photographing vision, and the robot is adopted for dust removal, so that the product quality and the assembling efficiency are improved.
