Description

Reactor for uniform coating and process automation and powder coating device with the same The present invention relates to a reactor for a powder coating device, and more particularly to a reactor for a powder coating device capable of maximizing uniform powder coating and process automation efficiency, and a powder coating device equipped with the same. With the recent expansion of the market for ultrafine nanoscale powders, various methods are being researched and developed to form high-quality thin films on large volumes of powder. For example, thin-film coated powder can improve the electrochemical and mechanical properties of batteries, and is therefore receiving attention as a technology that can lead the advanced semiconductor/battery market, such as active materials for cathode/anode materials and slurries for CMP (Chemical Mechanical Polishing). To coat such nanoscale thin films, processes such as CVD (chemical vapor deposition) and ALD (atomic layer deposition) can be applied. Among these, the P-ALD (Powder-Atomic Layer Deposition) method includes a reactor optimized for powder coating and is a technology that enables atomic layer deposition on the particle surface by maximizing the dispersion of the loaded powder. However, conventional rotary thin film deposition processes have several drawbacks. Due to the small internal volume of conventional reactors, the amount of powder that can be loaded per process is relatively small, resulting in a lower yield required for actual mass production. Additionally, manual connection between the reactor and chamber is required for each process, which limits the reduction of production time. To address these issues, mass production coating technologies and equipment structures that do not require manual connection of the reactor are being proposed. However, while these conventional technologies allow for a certain degree of automation in the connection between the reactor and the chamber, the problem of requiring human labor and manual operation during the powder recovery process still persists. In particular, although existing ultrafine nano-level powder coating technologies have faced difficulties in commercial production, efficient automated mass production technologies capable of continuous large-scale production—considering the unique nature of the coating target being powder—have not yet been proposed. In particular, for the reactor, a core component of the powder coating system, significant improvements were required not only to further enhance the uniform coating capability of the powder but also to ensure that engagement and disengagement with rollers, transfer, opening and closing, and precise alignment could be performed smoothly to increase automation efficiency.
