Coating device with dual shell structure for coating processes
The patent US12043897B2 describes a novel coating device designed to enhance the coating process for objects. The device features a dual-shell structure, comprising a first shell that includes a top and side portion, and a second shell that extends divergently downwards from the first shell's top portion. A key component of the device is a carrier seat that can move vertically between a highest and lowest position. This carrier seat includes a support post that provides gas from its top, a carrier plate for supporting the object to be coated, and a bottom plate. The configuration of the first and second shells creates distinct spaces: a first space surrounding a second space, which serves as a reaction region for the coating process, ensuring that the two spaces do not communicate with each other.
Further details of the coating device include the design of the second shell, which has an increasing diameter from top to bottom, and a wall mount for stability. The first space is maintained at atmospheric pressure, while the second shell is equipped with a gas channel and a gas barrier plate for gas dispersion. The carrier plate features an upward-facing surface with inlets for gas supply and vents for exhaust, facilitating efficient gas flow during the coating process. Additionally, the support portion of the carrier seat is designed with a gasket that has an inclined surface for better contact with the object. The device can accommodate multiple objects simultaneously, as the support portion includes a plate with hollows for this purpose. Overall, the design aims to optimize the coating process while maintaining separation between different gas environments.
