Abstract

The invention relates to a deep-well pump motor stator iron core detection method and device, and relates to the field of stator iron cores, and the method comprises the steps: carrying out the illumination of a preset stacking platform from top to bottom, and collecting the stacking image of a product stacked on the stacking platform of the stator iron core; shadow deepening is carried out on the product stacking image, and a central shadow contour of each stator iron core is obtained through identification; determining a clamping position based on the central shadow contour, controlling a preset transfer mechanism to clamp the stator core at any clamping position, and moving the stator core from the stacking table to a preset detection table position; industrial alcohol is sprayed to an inner cavity of the stator core, and a preset backlight source is controlled to irradiate from the stator core from bottom to top; performing image acquisition on the stator iron core at multiple angles under an irradiation condition to obtain an iron core image set; and performing image analysis on the iron core image set to obtain a detection result, and outputting the detection result. The detection efficiency of the stator core of the deep-well pump motor is improved.
