Abstract:
A transfer device of micro-elements and manufacturing method thereof are provided in the present disclosure. The transfer device of micro-elements may comprise a vacuum chamber, a plurality of movable mass blocks and a plurality of electrode assemblies. The vacuum chamber may define a vacuum space and a plurality of through holes. The plurality of through holes can communicate the vacuum space with outside. The plurality of through holes can be configured to suck the micro-elements. The plurality of movable mass blocks may be arranged in the vacuum chamber. Each movable mass block may be arranged corresponding to a through hole. The plurality of electrode assemblies may be fixed in the vacuum chamber. Each electrode assembly can be arranged corresponding to a through hole.
