1. A mass transfer apparatus, comprising:
a beam emission assembly configured to emit a beam;
a rotating lens configured to:
receive the beam emitted from the beam emission assembly; and
refract the beam to a substrate carrying a micro light emitting diode (LED) chip to be stripped; and
a rotating lens adjusting assembly connected with the rotating lens and configured to:
control the rotating lens to perform peripheral rotation; and
adjust a rotation radius of the rotating lens.
