AI Technical Summary

Technical Problem

Existing sorting equipment struggles to simultaneously achieve high-precision recognition of full-surface feature extraction, high-volume processing capacity, and compact equipment structure, resulting in issues such as blind spots and large footprint.

Method used

The design employs a conveyor roller mechanism, which uses a compact chain-like circulating conveyor structure with two parallel chains and multiple conveyor shafts to allow materials to rotate below the visual recognition mechanism. This enables complete extraction and high-precision recognition of all surface features. Meanwhile, the rejection mechanism completes the classification and rejection at the tail end, reducing the lateral space required for the equipment.

Benefits of technology

It achieves high-precision identification and high-volume processing of the full surface features of materials. The equipment has a compact structure, which improves sorting accuracy and output while reducing the floor space required.

Abstract

This invention discloses a visual sorting device and method for ellipsoidal materials, relating to the field of sorting equipment technology. The device includes a mounting frame, a material handling mechanism, a conveying roller mechanism, a visual recognition mechanism, and a rejection mechanism. The material handling mechanism is installed at the inlet end of the mounting frame, and the conveying roller mechanism is installed inside the mounting frame. When the material enters the visual area of ​​the visual recognition mechanism, the continuous arrangement of racks within this area ensures that the rollers continue to rotate reliably, allowing the material to rotate at least one revolution below the visual recognition mechanism. This enables the visual recognition mechanism to continuously capture multiple images covering the entire outer surface of the material, achieving complete extraction and high-precision recognition of the material's full surface features. Simultaneously, because the conveying roller mechanism employs a compact chain-type circulating conveying structure with two parallel chains and multiple conveying shafts, the material is arranged in a single, continuous, and dense row, resulting in high conveying efficiency and minimal lateral space occupation.
