During the annealing process, the rotary motor 504 can be started to drive the carrier plate 3 to rotate. The carrier plate 3 rotates inside the fixed ring 501.

[0048] like Figure 3 As shown, in a preferred embodiment, based on the above method, a ball bearing is evenly and rotatably mounted on the outer side of the bottom of the carrier plate 3, and the bottom of the ball bearing is in contact with the bottom of the annular groove 502.
