The invention discloses a robot, a robot-based trash auto-recycling method and device and a storage medium, wherein the robot does simple harmonic motion around a shoulder joint through a first mechanical arm such that waveform of an angle between the first mechanical arm and a horizontal line is sinusoidal; a second mechanical arm may do free rotational motion around an elbow joint; the second mechanical arm is driven by the first mechanical arm to periodically rock such that a T-shaped clamp reaches target trash. When the T-shaped clamp sucks the target trash, the second mechanical arm can freely rotate around the elbow joint so as to finely tune the position of the T-shaped clamp in contact with the target trash to gain more successful suction to the trash. The robot-based trash auto-recycling method includes: performing identity partitioning on trash through a neural network to obtain target trash, transmitting a command to the robot to grab the trash and put in a corresponding sorting mechanism; therefore, the trash is automatically classified, and the problems of low efficiency and poor trash sorting effect are avoided.

The effects of mechanical vibration on the microstructure and mechanical properties of AZ91 magnesium alloy were investigated via lost foam casting (LFC). The refining microstructure mechanism of the casting alloy under vibration force was also analyzed. The results show that mechanical vibration can produce finer dendrite in AZ91 alloy . The microstructure of AZ91 alloy via LFC consists of dominant α-Mg and β-Mg_ 17 Al_ 12 as well as a new phase Al_ 13 Mn_ 12 which is different from Al_ 32 Mn_ 25 in the untreated AZ91 alloy via LFC. The mechanical vibration can also strongly improve the mechanical properties of AZ91 alloy. The value of tensile strength of AZ91 alloy produced under vibration force of 1.5kN is increased by 27% compared to that under vibration force of 0kN and the mechanical properties is ultimate. However, the strength of AZ91 alloy drops due to the presence of the microporosity in the casting when the vibration force is increased. Mechanical vibration produces finer dendrite by increasing the undercooling degree, breaking dendrite into pieces by shear stress and melting the secondary dendrite arm.
