Embodiment 1
[0039]Embodiment 1, the present invention provides a kind of method that is used for the classification and selection of waste mobile phone materials, it is characterized in that: after the mobile phone is pretreated, mainly carry out the following several steps:
[0040] 1) Matching and identification, use the database to match and identify the items entering the process, and the gravity sensing device will measure and weigh them. If it is identified as a mobile phone, analyze the model and value of the mobile phone; if it is identified as a non-mobile phone, refuse to proceed to the next step;
[0041] 2) For the crushing of the mobile phone, a crushing device is used to cut the whole into small pieces;
[0042] 3) Grinding the mobile phone, using a grinding device to grind the cut pieces into powdery substances;
[0043] 4) For the purification of powder, a classification device is used to classify the powdery substances and collect them by category. refer to Figure 1 to...
Embodiment 2
[0044] Embodiment 2, the pretreatment of the mobile phone of the present invention includes cleaning the body, removing the battery, memory card and phone card of the mobile phone, and tearing off the mobile phone film on the surface. refer to Figure 1 to Figure 3 , and the rest are the same as the above-mentioned embodiment.
Embodiment 3
[0045] Embodiment 3, the matching recognition step of the present invention is realized by an image recognizer, scanning the item to obtain an image, and measuring and weighing through a gravity sensing device, matching with the database in the recognizer, and if it is determined to be a mobile phone, the brand of the mobile phone is given Model and recovery price and print a small ticket, send it to the crushing device in step 2, and the motor shaft will rotate forward for crushing; if it is determined that it is not a mobile phone, the main shaft of the crushing device in step 2 will reverse, and the item will exit the process. refer to Figure 1 to Figure 3 , and the rest are the same as the above-mentioned embodiment.
