Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A chip testing sorting device comprises a sorting platform 1, a first conveying platform 2 and a second conveying platform 4, wherein the first conveying platform 2 is fixed at the upper end of the sorting platform 1, and the second conveying platform 4 is located at one side of the first conveying platform 2. A plurality of chip bodies 3 are arranged on the first conveying platform 2, and a cavity 5 is arranged on the sorting platform 1 at one end of the second conveying platform 4, and a storage box 7 is arranged below the cavity 5. An air duct 10 is arranged on the first conveying platform 2, and an air pump 11 is arranged at the ventilation end of the air duct 10, and a grabbing head 12 is arranged at the output end of the air duct 10, and an air suction hole is arranged on the grabbing head 12. The chip bodies 3 to be sorted can be transported through the first conveying platform 2, and then the chips transported on the first conveying platform 2 are manually transported. The chip body 3 is sorted, and the air guide tube 10 is taken out. The switch on the air guide tube 10 can control the air suction and blowing of the air guide tube 10. During the air suction process, the air guide tube 10 can enable the grabbing head 12 to grab the chip body 3. When the air guide tube 10 is blowing, the chip body 3 can fall on the grabbing head 12, so that the chip body 3 on the first conveying platform 2 can be conveniently taken to the different second conveying platforms 4, and then the chip body 3 will be transported to the cavity 5 on the second conveying platform 4, and then fall into the storage box 7 at the cavity 5, which can provide a conveying structure for the chip body 3 on the sorting platform 1, so that the chip body 3 before sorting can be easily loaded, and the chip body 3 after sorting can be easily fed, thereby improving the sorting efficiency of the chip body 3;
