Intelligent production line for turning tool bit cavities and use method thereof

A production line for machining workpiece blanks, the production line comprising:

• a robot;
• material tables, each of the material tables comprising a respective material table base body and a respective plurality of trays, each of the trays being configured to receive a respective plurality of the workpiece blanks;
• a plurality of machining centers for clamping and machining the workpiece blanks;
• a protective fence surrounding the robot;
• wherein the material tables and the machining centers are arrayed about the robot such that the machining centers are outside the protective fence,
• wherein a respective transfer station for selectively receiving workpiece blanks from the robot and machined workpieces from the robot is arranged outside the protective fence and between each of the machining centers and the robot,
• wherein the protective fence is arranged to extend directly above the material tables such that part of each of the material tables is outside of the protective fence, and such that part of each of the material tables is inside of the protective fence;
• wherein the robot is provided with a mechanical arm, the mechanical arm comprises at least one clamping jaw, wherein the robot is configured to provide workpiece blanks to each of the machining centers;
• and
• wherein the trays are each driven so as to be slidable beneath the protective fence and relative to the corresponding material table base body so as to enable the workpiece blanks thereon to be moved from outside the protective fence to inside the protective fence where the workpiece blanks inside the protective fence can be picked up via the at least one clamping jaw.
