Problems solved by technology

The common droplet operation method is high-temperature evaporation or low-temperature condensation. The volume of the droplet is controlled by the mutual conversion between the gaseous state and the liquid state of water, which is convenient and flexible. However, this operation method requires the assistance of an external energy field to achieve reliable release of micro-components.

Abstract

The invention discloses an electrolytically-controlled micro-component picking and placing device and method, relates to micro-component control in the field of micro-assembly, and aims to solve the key problem that active release of micro-components is difficult to realize in the micro-component operation process. The device comprises a micro-driving motor, a mounting frame, two sleeves, a coupler, a ball screw, a connecting nut, a hexagonal mounting frame, six fixing frames, a long connecting rod, a hose, an electrode connecting piece, a movable electrode and six inert electrodes, wherein the mounting frame and the micro-driving motor are connected through four through hole bolts, the lower end of the long connecting rod is in threaded connection with the electrode connecting piece, the upper ends of the fixing frames are fixed in holes of the hexagonal mounting frame through screws, the six inert electrodes are fixed in grooves in the lower ends of the fixing frames through screws respectively and are tightly attached to the six side faces of the movable electrode, and the six inert electrodes are tightly attached to one another. The device is used for lossless pickup, posture adjustment and active release operation of the micro-components.

Description

technical field [0001] The invention relates to the manipulation of micro-components in the field of micro-assembly, in particular to an electrolytically controlled micro-component pick-and-place device and method. Background technique [0002] The manipulation of components with feature sizes in the millimeter and micron scales is an important operational task in the field of micro-assembly, and new methods of micro-component manipulation have become the focus of the field of micro-assembly. Among them, the manipulation method dominated by the adhesion of liquid media has the ability to pick up micro-components of different shapes softly, and has the advantages of no direct mechanical contact with the workpiece, avoiding damage to the workpiece surface, and automatic calibration. It has developed rapidly in recent years. Most of the existing methods for manipulating micro-components based on liquid media focus on the acquisition of liquid droplets, the pickup of micro-compo...
