Wafer Container Cover Alignment Guide Mechanism

The patent introduces guide members as intermediary elements that mediate between the cover and container body. These guide members extend along the central axis and provide physical guidance during the covering operation, ensuring proper alignment without requiring the user to manually align the central axes. The guide members act as a mediator that translates arbitrary placement into correct concentric alignment, eliminating the risk of wafer damage while maintaining sealing reliability.

The guide members are pre-installed on the container body before the covering operation. They extend from the bottom surface toward the opening, creating a predetermined alignment path. When the cover is placed over the container body, the guide members automatically guide the cover into correct concentric alignment, performing the alignment action in advance of the actual sealing operation and preventing misalignment damage.

The guide members serve as intermediary elements that prevent the cover side wall portion from directly contacting the wafers during the covering operation. By providing a guided alignment path, they ensure that the cover is positioned concentrically with the container body, preventing the cover side wall from colliding with the wafers even though the body side wall is larger than the wafer diameters to accommodate them.

The guide members are pre-positioned on the container body to establish correct alignment before the cover is placed. This preliminary alignment action ensures that when the cover is subsequently placed over the larger body side wall portion, the cover remains concentric and does not contact the wafers, thus preventing damage while maintaining the adaptable accommodation structure.

The guide members act as intermediary elements that facilitate manual covering operations by providing automatic alignment. When a user manually places the cover over the container body, the guide members extend along the central axis and physically guide the cover into correct concentric alignment, eliminating the need for the user to manually align the central axes. This maintains ease of operation while ensuring wafer protection reliability.

The guide members enable the covering system to self-align during manual operation. As the user places the cover over the container body, the guide members automatically guide the cover into correct concentric alignment without requiring user skill or attention to alignment. The system performs the alignment function itself, making the operation easy while ensuring reliable wafer protection.
