Flat enameled electromagnetic wire surface defect detection method based on deep learning

Abstract

The invention discloses a flat enameled electromagnetic wire surface defect machine vision detection method based on deep learning. The method comprises the following steps: 1, acquiring flat enameledelectromagnetic wire images: establishing a dark field environment, and acquiring a flat enameled electromagnetic wire image by using an area light source and a camera which are installed in a specified mode; 2, preprocessing the flat enameled electromagnetic wire image: segmenting an image of an area where the enameled wire is located by using a clustering algorithm; 3, identifying flaws of theflat enameled electromagnetic wire: training a convolutional neural network by using label data, and training a model to be called by a detection system to realize surface defect detection of the flatenameled electromagnetic wire. According to the method, the flat enameled electromagnetic wire image is acquired and preprocessed through a machine vision method, and the surface defects of the flatenameled electromagnetic wire are accurately identified through the convolutional neural network, so that the manpower input can be reduced, the detection cost is reduced, and the identification accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of surface defect detection of electromagnetic wires, in particular to a method for detecting surface defects of flat enameled electromagnetic wires based on deep learning. Background technique [0002] Product surface quality has always been a major concern in industrial production, and product surface quality will affect the commercial value and use value of the product. Electromagnetic wire, also known as winding wire, is an insulated wire used to manufacture coils or windings in electrical products. Magnet wires are generally divided into enameled wires, wrapped wires, enameled wrapped wires and inorganic insulated wires. Among them, the enamelled electromagnetic wire is made by coating the corresponding paint solution on the outside of the conductor, and then volatilizing the solvent, curing the paint film, and cooling. Problems such as unevenness and protruding defects lead to unqualified electromagn...
