Abstract: The present invention relaters to a method for continuously preparing a nano zinc oxide with a membrane reactor. A zinc salt solution and a precipitator solution required for the preparation of a zinc oxide are respectively used as dispersion phases, and under the action of a certain pressure, the two reaction solutions respectively penetrate through a membrane tube at a certain rate and disperse quickly under the action of a shear force and react, producing a precursor precipitate. A precursor suspension penetrates through the membrane tube continuously and circularly after being pressurized by a pump, and at the same time, deionized water as a washing fluid is added to a suspension storage tank, wherein impurity ions penetrate through membrane pores and are discharged along with the liquid medium; after the concentration of the impurity ions meets requirements, the concentrated solution is discharged continuously and then spray-dried to obtain a basic zinc carbonate precursor powder.

Abstract: Embodiments of the present application provide an apparatus for carrying a substrate by an off-line vacuum suction and a method for transporting a substrate. The apparatus includes a carrying frame provided with a clamper, a vacuum suction device and a detaching device arranged on the carrying frame, wherein the vacuum suction device is arranged to suck and fix a substrate and is connectable to and detachable from a vacuum pipeline and the detaching device is arranged to detach the vacuum suction device and the vacuum pipeline from each other while keeping the vacuum suction device to continuously suck the substrate to be transported. The apparatus and the method can improve fixing of the substrate and achieve off-line suction to the substrate.

Abstract: The present disclosure provides a roller assembly including: a support base provided with a shaft hole; and at least two circular arc segments that are detachably mounted on the support base, wherein the at least two circular arc segments constitute a roller and a vertical distance from any point on periphery of the roller to an axis of the shaft hole is larger than a vertical distance from any point on periphery of the support base to the axis of the shaft hole. The present disclosure also provides a transmission device including a roller assembly described above.

Abstract: The disclosure provides a substrate supporting pin, a substrate supporting device and a substrate access system. The substrate supporting pin is used to support a substrate and includes a rod body. A supporting end of the rod body is provided with a rotating member that is able to roll along a surface of the substrate. Compared to the prior art, the disclosure can reduce or eliminate the damage of the substrate.
