▎ 摘  要

NOVELTY - The device has a box body (10) provided with multiple containing cavities (101) at interval. Each of the containing cavities is a hollow area extending from a bottom part of the box body to a top part of the box body. The top part of the containing cavities is configured to irradiate an external laser through itself to the containing cavity. One surface of an adhesive layer (12) away from the containing cavity is configured to adhere a light emitting chip (3). The gravity of movable graphene is less than the adhesive layer to the graphene force of a movable piece. The movable graphene is configured to generate a photoelectric effect under the irradiation of the external laser to generate the same force with the gravity direction. USE - Transfer device used in light emitting diode (LED) technology field. ADVANTAGE - The device does not need to press the transfer device and the circuit backplate, and ensures the successful transfer of the LED. The device reduces the between the LED chip and the adhesive layer of the contact layer, so as to reduce the adhesive force between the two is less than the gravity of the LED. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: A transfer system; and A transfer method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the transfer device. 2Laser source 3Light emitting chip 10Box body 11Graphene movable piece 12Adhesive layer 101Containing cavity
