The invention discloses a working mechanism of a single-
station feeding production
processing system based on a mechanical arm. The working mechanism is characterized in that the single-
station feeding production
processing system comprises a mechanical arm, a
conveyor belt, an industrial camera, a cache
library with capacity being M, a finished product warehouse with capacity being N and workpieces, wherein the mechanical arm is used for obtaining vacant amount m of the cache
library and a gripper position p under a current state; and a
visibility distance Vsmp is selected according to an
optimal control strategy v*; and if workpiece are within the
visibility distance Vsmp, unloading operation is carried out; and if the workpieces are not within the
visibility distance Vsmp, service operation is carried out. The
optimal control strategy v* is obtained by carrying out optimization solution on an SMDP model which is established by taking the vacant amount m of the cache
library and the gripper position p as states through a strategy iteration
algorithm. The working mechanism can be used for improving process balance and production efficiency of a single-
station mechanical arm
production line which has no fixed beat, has random
material supply and has no fixed-point
processing, so that basis is provided for
optimal scheduling of the single-station mechanical arm
production line in industrial production.
