  • Patent number: 11952662
    Abstract: Disclosed is a powder atomic layer deposition equipment with a quick release function, comprising a vacuum chamber, a shaft sealing device, and a driving unit connected to the shaft sealing device. The vacuum chamber is connected to the shaft sealing device, and an enclosed space is formed between the vacuum chamber and the shaft sealing device. At least one air extraction line is located in the shaft sealing device and fluidly connected to the enclosed space, the air extraction line being used in pumping gas out from the enclosed space to fix the vacuum chamber to the shaft sealing device so that the drive unit rotates the vacuum chamber via the shaft sealing device to facilitate the formation of a uniform thin film on powder surface. When the pumping stops, the vacuum chamber can be quickly released from the shaft sealing device to improve the process efficiency and convenience of use.

  • Publication number: 20220341036
    Abstract: The present disclosure provides a powder-atomic-layer-deposition device with knocker, which mainly includes a vacuum chamber, a shaft seal, a drive unit and a knocker. The drive unit is connected to the rear wall of the vacuum chamber via the shaft seal, for driving the vacuum chamber to rotate. The shaft seal includes an outer tube and an inner tube, wherein the inner tube is disposed within the containing space of the outer tube. The inner tube is disposed with a gas-extracting pipeline and a gas-inlet pipeline therein, wherein the gas-extracting pipeline is for gas extraction of the vacuum chamber, the gas-inlet pipeline is for transferring a precursor gas into the vacuum chamber. The knocker and the vacuum chamber are adjacent to each other, for knocking the vacuum chamber to prevent powders within the reacting space from sticking to the inner surface of the vacuum chamber.
