The invention relates to a drilling tool code
recognition system comprising coding chips, a portable
infrared scanner and a computer, wherein coding chips are two round anti-
corrosion hard-plastic flakes with small holes in the centers, and each flake is engraved with a two-dimensional digital code of the same drilling tool; a
blind hole is drilled in an area on a male connector of the drilling tool, adjacent to a slope table shoulder side, one coding
chip is placed at the bottom of the
blind hole, an anti-
corrosion fluororubber pad with the outer
diameter same to the size of the
blind hole is covered on the coding
chip, the other coding
chip is placed on the fluororubber pad, with the surface engraved with the two-dimensional digital code upward, and finally, a small quantity of steel
adhesive is applied on the inner side of the blind hole, tightly adjacent to the coding chips, so as to fix the coding chips; the
corrosion and high-temperature resistant fluororubber pad in the coding chips can be used for isolating the chip at the bottom layer with a
working environment so as to effectively protect the chips; and the portable
infrared scanner improves the efficiency and accuracy of code recognition, avoids errors caused by manually recording codes, and promotes the
digitization and the
informatization of drilling tool coding management.
