The present disclosure relates to an expanding and radiative flow mechanism. The mechanism has a bottom surface. The bottom surface is provided with a fluid supply port. The bottom surface of the mechanism and a surface of a to-be-adsorbed object form a gap during use. A fluid flows out from the fluid supply port, enters the gap and flows out along the gap. The gap is an expanding gap and meets the following: a radial length exists with the fluid supply port as an initial point of the flow, and a height of the gap continuously increases in an outward radial direction within this length. With improvements to a parallel radiative flow mechanism, the mechanism of the present disclosure can effectively increase an absorption force of a radiative flow, which is conducive to subsequent applications thereof.

Expanding and radiative flow mechanism

The present invention relates to a turntable mechanism, including a flat plate and a rotating device for driving the flat plate to rotate, where the flat plate rotates to generate a negative pressure between a lower surface of the flat plate and a surface of an adsorbed object, the flat plate and the adsorbed object adhere together by an adsorption force generated by the negative pressure, and in this case, a gap is kept between the lower surface of the flat plate and the surface of the adsorbed object. In the present invention, a continuous, consistent, and stable fluid film is formed between the turntable and the adsorbed object, and a secondary flow is not easily generated, thereby ensuring that the adsorption force between the rotating flat plate and the adsorbed object is more stable.
