automatic feeding, reading loading box identification codes (each product corresponds to one identification code) → the system acquires the product type of the whole box → one disk in the loading box is taken out and the code is read → the inspection is wrong or missing → the reading is finished and the other disk is put back to the electrostatic box → the whole box is OK to flow out, the code scanning of each product on the rack is finished, and then the basis is provided for the storage, and meanwhile, if NG exists in the inspection, the product enters an NG cache area, and the alarm prompt and the manual processing are carried out.

However, the storage code scanning process has the following defects:

1) the loading boxes are unified standard parts, and the types of products are diversified, so that the size of the selected rack tray can be changed, and thus when the loading boxes take out the rack tray, the material taking standards are unified, so that when the rack trays with different sizes are taken and placed, the phenomenon that the tray taking is misplaced or the tray taking fails occurs, and inconvenience is brought to actual code scanning detection;

2) when the code is photographed and read, the products are basically operated one by one, so that the efficiency is low, missing photographing or missing code scanning (missing detection) of the products is easily caused, and NG products are directly discharged from manufacturers;

3) the frame dish after taking out from the loading case is through detecting the back, can't directly deposit to original loading case in, must detect out a mouthful department and stack, wait to all vacate the frame dish after, will load the case and remove to detecting out a mouthful department again, deposit to the loading case by the manipulator of fetching material with a frame dish one by one again, consequently, at the vanning in-process after the detection, not only influenced the efficiency of vanning, and must accomplish preceding vanning work after, could carry out the material detection work of getting of next loading case, and then also influenced the efficiency of detection.
