10. the two-stage planetary gear type polishing carrier for 3D curved glass according to claim 5, wherein a clutch stress plate (226) selectively engaged with the main planetary gear (223) is sleeved on the transmission spindle (221), the clutch stress plate (226) is disposed right below the main planetary gear (223), a linear bearing (2261) sleeved on the transmission spindle (221) is disposed between the clutch stress plate (226) and the transmission spindle (221), so that the clutch stress plate (226) can slide up and down along the transmission spindle (221) while rotating along with the transmission spindle (221), and a centrifugal stress groove recessed inward is disposed on an outer periphery of the clutch stress plate (226).

11. the two-stage planetary gear type polishing carrier for 3D curved glass according to claim 10, wherein at least one set of centrifugal assemblies (25) below the plane of the sun gear (34) is arranged at the loading and unloading station (331).

12. the two-stage planetary gear-type polishing carrier for 3D curved glass according to claim 11, wherein the centrifugal assembly (25) comprises:

A clutch support (251) located below the plane of the sun wheel (34);

a clutch driver (252) arranged on the clutch bracket (251); and

A clutch power plate (253) connected with the power output end of the clutch driver (252),

the clutch power plate (253) extends along the horizontal direction and is inserted into the clutch force-bearing groove, and the clutch power plate (253) selectively moves up and down under the driving of the clutch driver (252) so that the clutch force-bearing plate (226) is selectively clamped with the main planetary gear (223).
