[0046] Step S1: clamping the thin plate 500. The upper clamp 203 and the lower clamp 204 clamp the thin plate 500 together.

[0047] Step S2: Immersion. The thin plate 500 from step S1 is gripped by the clamping mechanism 200 and immersed in the immersion mechanism 400. The waterfall guide mechanism 300 provides a cascade of liquid flowing downward into the immersion tank, while also providing a surge of liquid from opposite sides above the tank, simultaneously sinking the thin plate 500 into the tank.

[0048] Step S3: Moving. The thin plate 500 in step S2 is moved along the length direction of the immersion tank by an electromagnetic device. In this embodiment, the electromagnetic device uses a motor as a power source.
