Description

Cassette transfer device for display products {APPARATUS FOR TRANSFERRING CASSETTE OF DISPLAY DEVICE}

The present invention relates to a cassette transfer device for display products. In particular, the present invention relates to a cassette conveyance transfer device for a display product, which is capable of safely transferring parts while maintaining cleanliness, and enabling multi-stage stacking for each floor.

Typically, display products, such as Liquid Crystal Display (LCD) and Plasma Display Panel (PDP) products, are manufactured in a clean room, and the clean room is installed in multiple floors of a factory building. Then, the display products are manufactured while conveying the parts or semi-assemblies constituting the display products to the clean rooms on each floor.

The parts or semi-assemblies are transported in a cassette, and a lift path is provided on one side of the clean rooms for transport between floors, and a lifter car is installed on the lift path so as to be liftable. Or in the clean room, the transfer device which moves a cassette between a lifter car and a clean room is installed. In addition, a clean room entrance is formed at the boundary wall of the clean room and the hoistway, and a lifter car entrance is formed at the clean room side wall of the lifter car, and these doors are opened and closed by the clean room door and the lifter car door, respectively.

A process of transferring a cassette containing parts or semi-assemblies by a conventional apparatus to a clean room of each floor will be described.

When the lifter car is lifted and stopped at the desired clean room position, the clean room door is first opened, and the clean room is filled with clean air to maintain a constant pressure. Therefore, the clean air in the clean room passes through the boundary room and the lifter through the clean room entrance. As it flows out of the gap between the cars, it prevents the air on the lift side from entering the clean room. When the lifter car door is opened in this state, the clean air in the clean room flows into the lifter car and the air inside the lift road or the lifter car To prevent the air from entering the clean room. The hoistway here is typically of a lower grade than clean rooms and lift car interiors, but maintains the conditions of the clean room to some extent.

The pressure inside the cleanroom, lifter car, and hoistway is the highest in the cleanroom, followed by the lifter, and then the hoistway, which prevents air from entering the areas from the lowest pressure to the next.

When the doors are opened. The transfer device installed in the lifter car or the clean room transfers the cassette into the clean room or the lifter car.

When the cassette is reloaded, first close the lifter car door and then close the cleanroom door.

When the doors are closed, the lifter car moves up and down along the hoistway to stop in the clean room of the other floor to which the cassette is to be transferred. As described above, the clean room door is opened first and then the lifter car door is opened. The cassette is transferred to the interior of the clean room or the lifter car, and then the lifter car door is closed as described above, and the clean room door is then closed.

This transfers the cassette in any one clean room to the desired clean room.

However, in the conventional apparatus, since the lifter car must be moved after touching the lifter car door and the clean room door sequentially, as described above, there is a problem in that the transfer and transfer of the cassette takes a lot of time.
