Large-size target material processing full-process automatic production line and target material production method

The invention discloses a large-size target material processing full-process automatic production line and a target material production method, and belongs to the technical field of target material processing. The automatic production line is arranged linearly and comprises a ground rail, a robot cache tray, a robot, an MES system device, a machine tool, a workpiece overturning table, an ultrasonic cleaning pool, a feeding table and a discharging table. The three machine tools are arranged to machine the workpiece, the robot is moved through the ground rails and the robot cache tray which are arranged in front of the machine tools in parallel, and the workpiece carrying action is completed by controlling the robot. Meanwhile, the workpiece overturning platform is arranged and matched with robot carrying for workpiece overturning, and manual work is replaced to reduce the labor cost; a scratch-proof clamp is arranged in the machine tool, so that the scratch of the target material can be further reduced; hollow
