thirteenth, cleaning, drying and rust preventing of the product:
the product subjected to nondestructive inspection enters a cleaning machine (26) to finish surface cleaning of the product, then enters a dryer (27) to finish drying of residual water stains on the inner and outer surfaces of the product, and then enters a storage table (29) to wait for product code scanning and packaging;
fourteen, code scanning packaging:
an operator takes down the product from the material storage table (29), and the product is scanned under a code scanning gun of a code scanning area (30), automatically uploads and stores related information; finally, the products after the code scanning operation are framed in a packaging area (31).
