Visual detection method for motor

Abstract

The invention aims to provide a visual detection method for the motor, which can realize full-automatic appearance detection and greatly improve the appearance detection effect and efficiency of the motor. Four detection stations are adopted, and the motor is sequentially conveyed into the four detection stations through a conveying mechanism. The detection of small shell damage, terminal deformation, reverse installation of a coding magnet, poor terminal height, unbuckled small shell of the pressing claw of the motor, missing of a pressing claw of the motor, missing of the coding magnet, poor height of the coding magnet, omission of the coding magnet, reverse pasting of a label, missing or smudginess of a label two-dimensional code, no size of the two-dimensional code and the edge of the label in a specification range, repeated labeling, wrong labeling positions, inclined labeling, labeling omission, writing of a large shell, screw hole damage, shaft damage, gear oxidation, tapping omission of a large shell, foreign matters in screw holes, gear damage and other defects can be carried out. The method can be applied to the field of appearance detection of products such as motors and inductors.

Description

technical field [0001] The invention relates to a method for detecting the appearance of a motor, in particular to a method for visually detecting a motor. Background technique [0002] In the process of motor production, in order to ensure the quality of the product, it is necessary to carry out factory inspection of various indicators of the product, among which appearance inspection is a key indicator of product inspection. At present, most of the appearance inspections are carried out by manual inspection. This method is greatly affected by human subjectivity, so it is difficult to ensure consistency. In addition, as customers have higher and higher requirements for product quality, it is necessary to conduct all-round inspections on the appearance of the motor, such as small shell damage, terminal deformation, reversed coding magnets, poor terminal height, and one of the motor's pressure claws is not buckled. Small shell, motor leak pressure claw, missing coding magnet...

At present, most of the appearance inspections are carried out by manual inspection, which is greatly affected by human subjectivity, so it is difficult to ensure consistency

In addition, as customers have higher and higher requirements for product quality, it is necessary to conduct all-round inspections on the appearance of the motor, such as small shell damage, terminal deformation, reversed coding magnets, poor terminal height, and one of the motor's pressure claws is not buckled. Small shell, motor leak pressure claw, missing coding magnet, bad height of coding magnet, missing coding magnet, reversed label, missing or dirty QR code on label, edge size of QR code and label not within the specification range, repeated stickers Wrong position of labels and labels, crooked labels, missing labels, handwriting on large shells, damage to screw holes, shaft damage, gear oxidation, missed tapping on large shells, foreign objects in screw holes, and damage to gears. way is difficult to meet the production demand
