Acoustic levitation is a container-less processing technique that uses the acoustic radiation force generated by a strong acoustic wave to counteract gravity to achieve object levitation.

The lower sound wave probe 3 firstly emits a sound source to enable an object to suspend, meanwhile, the radiator radiates heat to the lower sound wave probe 3 through liquid cooling, and the suspension effect is poor due to the fact that the lower sound wave probe 3 is used for too long. Before the suspension effect of the lower acoustic wave probe 3 becomes poor, the upper acoustic wave probe 2 starts to emit a sound source at the highest point of the effective distance of the fourth screw 52, and the radiator 75 starts to cool the upper acoustic wave probe 2. The fourth motor 53 drives the fourth screw 52 to slowly descend the upper acoustic wave probe 2, so that the suspension effect on objects is enhanced. When the object can be fixed, the lower sound wave probe 3 is closed, and the upper sound wave probe 2 continues to provide levitation force for the object. The radiator 75 continuously radiates heat to the lower acoustic wave probe 3 so as to restore the levitation effect. Before the suspension effect of the upper acoustic wave probe 2 is reduced, the fourth motor 53 drives the fourth screw 52 to enable the upper acoustic wave probe 2 to move upwards, but the stable effect on objects is maintained, after the upper acoustic wave probe 2 is lifted to a certain distance, the lower acoustic wave probe 3 starts to work, and the exchange of the working states of the upper acoustic wave probe 3 and the lower acoustic wave probe 3 is realized, so that the continuous working effect is realized.

And the upper and lower sonic probes can alternately work and suspend the object, and when one sonic probe works, the other sonic probe stops working and waits for the temperature to drop so as to restore the suspension effect on the object. Therefore, the device is beneficial to the long-time operation of the transducer of the acoustic wave probe in a high-power operation state.

The second lifting mechanism enables the upper acoustic wave probe to move up and down. The lower sound wave probe firstly emits a sound source to enable an object to suspend, meanwhile, the radiator radiates heat to the lower sound wave probe through liquid cooling, and the use time of the lower sound wave probe is too long, so that the suspension effect is poor. Before the suspension effect of the lower sound wave probe is poor, the upper sound wave probe starts to emit a sound source at the highest point of the effective distance of the fourth screw, and the radiator starts to cool the upper sound wave probe. The fourth motor drives the fourth screw rod to enable the upper sound wave probe to slowly descend, and the suspension effect on objects is enhanced. When the object can be fixed, the lower sound wave probe is closed, and the upper sound wave probe continuously provides levitation force for the object. The radiator continuously radiates heat to the lower sound wave probe so as to restore the suspension effect. Before the suspension effect of the upper acoustic wave probe descends, the fourth motor drives the fourth screw rod to enable the upper acoustic wave probe to move upwards, but the stable effect on objects is maintained, after the upper acoustic wave probe ascends to a certain distance, the lower acoustic wave probe starts to work, and the exchange of the working states of the upper acoustic wave probe and the lower acoustic wave probe is achieved, so that the continuous working effect is achieved.
