Color sorting method for copper and aluminum foil particles of battery cell broken product of power battery

Abstract

The invention provides a color sorting method for copper and aluminum foil particles of a battery cell broken product of a power battery. The core concept of the color sorting method is that a white hole region inside a binary image of the copper and aluminum foil particles of the battery cell broken product of the power battery is extracted as a characteristic value for separating aluminum foil particles from copper foil particles. According to the color sorting method provided by the invention, the characteristic value for color sorting is based on textural features of the copper and aluminum foil particles of the battery cell broken product of the power battery rather than color features, so the separation results are quite accurate. Compared with the prior art, the color sorting methodprovided by the invention has the beneficial effects that (1) the color sorting method is simple and quick in treatment and greatly improves the accuracy of separation of the copper and aluminum foilparticles; and (2) the color sorting method provided by the invention is applicable to simple software and hardware environments, low in cost and convenient for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a color sorting method for copper and aluminum foil particles of power battery cell crushing products. Background technique [0002] With the increase in the number of new energy vehicles, the scrapped amount of power batteries has increased sharply, the depletion of resources and the environmental problems it brings, the recycling of power batteries will show great value. The recycling methods of waste power batteries mainly include fire method, wet method, biological method and mechanical method. However, pyrolysis has the characteristics of high energy consumption and serious waste gas pollution. Wet recovery needs to consume a lot of strong acid, strong alkali, strong oxidizing agent and extractant, and generate a lot of waste liquid at the same time. Biological recovery uses biological acid instead of traditional sulfuric acid and nitric acid, which ha...
