When it is determined that it is a defective product or a product whose barcode cannot be recognized by the scanning and identification module 3, the fifth XYZ-axis moving mechanism 511 drives the fifth suction module 512 to suck the defective product and move it to the defective product receiving module 52, and the defective product receiving module 52 drives the defective product receiving table 522 to gradually descend through the fifth Z-axis moving mechanism 521 for receiving the material.

[0046] When passing through the corresponding sorting and discharging module 6, the sixth YZ-axis moving mechanism 611 drives the sixth suction module 612 to grab the corresponding qualified products (the corresponding qualified products are judged by scanning the code by the scanning and identification module 3), and moves them to the good product table 622 of the good product receiving module 62, thereby completing the material separation.
