Abstract

The invention discloses an ultrasonic suspension device applied to the field of three-dimensional (3D) printing. The ultrasonic suspension device applied to the field of 3D printing comprises a frame, a workbench, a piezoelectric transducers, suspension supporting mechanisms and a suspension guiding device. The workbench comprises a printing working platform, two driving motors and a supporting working platform. The number of the suspension supporting mechanisms is two; each suspension supporting mechanism is provided with one piezoelectric transducer; the center line of one piezoelectric transducer is in the front-back direction; the center line of the other piezoelectric transducer is in the left-right direction; and the layout form that the center lines of the two piezoelectric transducers are mutually orthogonal is formed. According to the ultrasonic suspension device applied to the field of 3D printing provided by the invention, the stability of radiation force generated by radiation heads and reflection ends of the piezoelectric transducers can be ensured by fixing the piezoelectric transducers in the orthogonal direction in the plane by using the suspension supporting structures. According to the ultrasonic suspension device applied to the field of 3D printing provided by the invention, the reciprocating motion of the ultrasonic transducers is indirectly controlled, so that the suspension position of particles in resonant cavities of the piezoelectric transducers is changed, and the controllability of stable suspension of the particles in the in-plane suspension motion process is realized.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic levitation, in particular to an ultrasonic levitation device applied in the field of 3D printing. Background technique [0002] With the development of technologies such as materials industry, biochemical analysis, and droplet surface hydrodynamics, people's requirements for experimental conditions are gradually increasing. However, under traditional contact experimental conditions, the container wall will inevitably come into contact with the research sample, which will cause a certain degree of pollution to the research sample, but the non-contact non-container technology can well avoid this problem. [0003] Among many levitation technologies, although electromagnetic levitation is currently the most widely used and most mature levitation technology, it requires the object to be a conductive material, so it cannot levitate inorganic glass, organic materials, ceramics, rubber, plastics, etc. ...
