1. An automatic identification and classification production line for waste mobile phones, comprising:
a feeding device configured to accommodate a plurality of waste mobile phones and to orderly and directionally arrange and sequentially convey the waste mobile phones;
an automatic separation feeding device configured to intermittently separate the waste mobile phones conveyed by the conveying device;
a conveying chain, comprising an annular chain and a plurality of transparent boxes, wherein the annular chain is horizontally arranged in the annular axial direction, and the annular chain is configured to intermittently and rotationally move;
the transparent boxes all mounted on the annular chain, and the end, away from the annular chain, of each transparent box is an open end;
wherein the automatic separation feeding device is configured such that the waste mobile phones separated by the automatic separation feeding device intermittently fall into the transparent boxes, and each transparent box stores one waste mobile phone;
a data acquisition device, comprising a detection frame, two plane mirrors, a video camera and a light source, wherein the conveying chain passes through the detection frame;
the two plane mirrors are both mounted in the detection frame and are vertical to each other;
the video camera is mounted on the detection frame;
the light source is mounted on the detection frame and is configured to emit light rays to the space between the two plane mirrors; and
the annular chain and the transparent boxes are configured such that when the annular chain rotates, each transparent box passes through an area between the two plane mirrors, so that the front surfaces or the back surfaces of the waste mobile phones in the transparent boxes are located in a shooting area of the video camera, and the other surfaces of the waste mobile phones visible through the bottom of the transparent boxes, are imaged by the two plane mirrors and then appear on the same shooting surface of the video camera together with the front surfaces or the back surfaces;
a computer identification device configured to firstly extract feature information of each waste mobile phone according to front and back images, shot by the video camera, of the waste mobile phones and then carry out identification and classification on each waste mobile phone according to the feature information;
a conveying device configured to receive the waste mobile phones going through the detection frame and falling off from the conveying chain and convey the waste mobile phones in sequence; and
a classified storage device configured to classify and store the waste mobile phones conveyed by the conveying device according to the types of the mobile phones on the basis of identification and classification results of the computer identification device.
