Color sorting machine

Abstract

The invention discloses a color sorting machine comprising a conveying mechanism, an optical signal acquisition mechanism and a sorting actuator; the conveying mechanism is arranged on the front side of the optical signal acquisition mechanism and used for conveying a material to an optical signal acquisition mechanism and tossing; the optical signal acquisition mechanism includes an illumination system and an image acquisition device; the illumination system is located above a material tossing track, and the image acquisition device is located above the illumination system; the illumination system comprises two striped lamp tubes horizontally arranged and perpendicular to the conveying direction of a conveying belt, the tubes are each arranged in a lampshade, and the two lampshades are arranged at intervals; the image acquisition device is arranged just above a gap between the two lampshades; light illuminated from the two lampshade illuminates downwards tilted and are intersected just below the gap. By adopting the color sorting machine, a local shadow can be prevented from being generated on the upper end face of the material, so that the image acquisition device can acquire a clear material image, the error is avoided, and good recognition effect is achieved.

Description

technical field [0001] The invention relates to a color sorter, in particular to the technical field of copper waste recycling and sorting. Background technique [0002] The color sorter is a device that uses photoelectric detection technology to automatically sort out the different-color particles in the granular material according to the difference in the optical characteristics of the material. As an excellent material sorting equipment, the color sorter is widely used in grain processing, ore sorting and other industries. The color sorter as a whole includes key components such as the conveying mechanism, optical signal acquisition mechanism, and sorting actuator. The material is transported to the optical signal acquisition mechanism through the conveying mechanism, and the image data of the material is collected by the optical signal acquisition mechanism and analyzed by the host computer. After the analysis, the sorting actuator is used to separate the materials to be...

Problems solved by technology

The optical signal acquisition mechanism is a crucial core component, which is directly related to the effect of sorting. The optical signal acquisition mechanism includes an illumination system and an image collector. For images, if the light cannot be evenly illuminated on the surface of the material, and it is only illuminated from one direction, shadows are likely to appear on the backlight side of the material, and the shadows are likely to cause color deviations in the collected images and cause sorting errors; on the other hand, With the long-term use of the equipment, due to the dust carried by the material, the lower end surface (light incident end surface) of the image collector will be covered with a layer of dust, which needs to be cleaned frequently, but because the image collector is installed in the casing , it is very inconvenient to open the case when cleaning; moreover, long-term use will cause the white balance of the image collector to deviate, resulting in inaccurate colors of the collected images, which will affect the sorting effect and cause large errors
