Abstract: Provided are a transferring device and a transferring method of a micro light emitting diode. During the transferring process of the micro light emitting diode, the state of the magnetorheological fluid is controlled to achieve the physical connection of the micro light emitting diode and the transferring head to increase the acting force between the micro light emitting diode and the transferring head, thereby preventing damage during the transfer process of the micro light emitting diode for reducing the difficulty of transferring the light emitting diode. Moreover, with the simple electromagnetic device to control the connection and separation of the micro light emitting diode and the transferring head, the transferring operation of the micro light emitting diode is simplified to promote the transferring efficiency of the micro light emitting diode.

Abstract: An end effector that includes: a flexible container which contains a filler, wherein the filler is switchable between a flowable or deformable state and a rigid or dimensionally stable state, and one or more working elements for gripping, temperature regulation and/or compaction.
