Non-contact transporting apparatus

A non-contact transporting apparatus, comprising:

• a negative pressure assembly configured to generate a negative pressure airflow within the non-contact transporting apparatus;
• and
• an ultrasonic assembly connected to the negative pressure assembly, the ultrasonic assembly comprising:
• an ultrasonic transducer configured to convert a high-frequency ultrasonic electrical signal into a high-frequency mechanical vibration, one end of the ultrasonic transducer being connected to the negative pressure assembly;
• an ultrasonic horn configured to amplify the high-frequency mechanical vibration, one end of the ultrasonic horn being connected to one end of the ultrasonic transducer away from the negative pressure assembly;
• and
• an ultrasonic chuck configured to amplify and convert the high-frequency mechanical vibration, the ultrasonic chuck being connected to one end of the ultrasonic horn away from the ultrasonic transducer;
• wherein the ultrasonic transducer comprises a transducer body, a piezoelectric ceramic stack, and a transducer connecting portion;
• the ultrasonic transducer body defines an accommodating cavity, the piezoelectric ceramic stack is accommodated in the accommodating cavity;
• one end of the transducer connecting portion is connected to one end of the transducer body away from the negative pressure assembly.
