Abstract

The invention discloses a micro-jetting adhesive dispensing driving device. The device comprises an upper driving unit 1, a lower driving unit 2, a swinging unit 3 and an output unit 4; the two driving units are symmetrically arranged on two sides of the swinging unit; each driving unit adopts the flexible structure comprising a plurality of flexible hinges and rod pieces, and leftward-and-rightward micro-amplitude swinging of the rod pieces connected with the swinging unit is realized through elastic deformation of the flexible hinges; the swinging unit comprises a flexible hinge and a T-shaped rod, leftward-and-rightward swinging of the driving units is transferred to the swinging unit through elastic deformation of the flexible hinge, and up-and-down micro-amplitude swinging of the swinging unit is realized; the output unit comprises two symmetrically-arranged arc-shaped flexible beams and a striker fixing rod, up-and-down swinging of the swinging unit is transferred to the output unit through elastic deformation of the arc-shaped flexible beams, up-and-down micro-amplitude swinging of the rod pieces for mounting strikers is realized, and the micro-jetting function is realized.The designed micro-jetting adhesive dispensing driving device can be used in the fields of bioengineering, rapid manufacturing, electronic packaging and the like.

Description

technical field [0001] The invention relates to a micro-jet dispensing driving device, which belongs to the liquid distribution technology and is mainly used in the fields of bioengineering, electronic packaging, rapid manufacturing and the like. Background technique [0002] In recent years, with the rapid development of cutting-edge fields such as life sciences, electronic packaging, and rapid manufacturing, the requirements for the distribution and transfer of liquid materials have become higher and higher. In these fields, the frequency, accuracy, and volume of liquid distribution, etc. Situations have different requirements. The traditional dispensing system is limited by its working principle and driving mode, making it difficult for its glue dispensing accuracy and speed to meet the requirements of accurate and fast dispensing. [0003] The micro-jet dispensing drive device uses piezoelectric ceramics as the drive, and uses the inverse piezoelectric effect of piezoel...
