Automatic laser engraving machine for flat-spraying keys

The utility model discloses an automatic laser engraving machine for flat spraying keys, which comprises a split type double-station three-dimensional feeding bin mechanism, a double-station linear motor, a double-station tray carrying and fine positioning mechanism, a double-station linear motor three-axis double-head single-action material taking mechanism, an integrated double-station three-dimensional discharging bin and the like. A second bevel gear is rotationally connected into the gear groove, the second bevel gear is fixedly connected with a reciprocating lead screw, an air blowing box is fixedly connected to the inner wall of the gear block, the gear strip is fixedly connected with a piston, and a sliding device enabling the gear strip to slide is installed in the gear groove. And through the arrangement of an air blowing box and a gear strip, when a reciprocating lead screw rotates, air in a strip-shaped groove can be blown out through a second connecting pipe through sliding of a piston, so that d
