Automatic stacking system and method based on numerical control hoop bending machine

According to the automatic stacking system and method based on the numerical control hoop bending machine, a belt conveyor, a robot and a containing table are arranged, a sliding rail is arranged at a discharging opening of the numerical control hoop bending machine, the bottom of the sliding rail is located above a conveying belt of the belt conveyor, and the containing table is arranged on the left side of the conveying belt. Stirrups machined by the numerical control hoop bending machine slide to the conveying belt from the discharge port through the sliding rail and are conveyed to the placing table. And a mechanical arm of the robot is provided with a stirrup grabbing device which is used for grabbing the stirrups on the placing table and placing the stirrups at preset positions. According to the stacking system, the stirrups machined by the numerical control hoop bending machine are conveyed to be placed through the belt conveyor, then the robot and the mechanical arm of the robot are adopted for grabbi
