Benefits of technology

The invention prevents the latch pin from rattling when it moves by adding latch pin guides around the door frame.

Problems solved by technology

However, when substrates accommodated in a cassette are transferred and stored, foreign substances adhered to a worker or floating in the clean room may easily penetrate into the cassette, and may adhere to surfaces of the substrates.
As such, the flat display devices may deteriorate.

Abstract

A cassette for accommodating substrates may include a cassette body for accommodating the substrates; a door for selectively sealing the cassette body; magnetic units for primarily coupling the door to the cassette body; and latch units for secondarily coupling the door to the cassette body. Since the door completely contacts the cassette body, penetration of a contamination source from an external environment may be fundamentally prevented. Also, since the door is double coupled to the cassette body by the magnetic units and the latch units, firm coupling may be achieved.

Description

CLAIM OF PRIORITY[0001]This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application earlier filed in the Korean Intellectual Property Office on Jul. 7, 2011 and there duly assigned Serial No. 10-2011-0067537.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a cassette, and more particularly, to a cassette for accommodating substrates to prevent contamination when the substrates are transferred or stored.[0004]2. Description of the Related Art[0005]Generally, flat display devices such as an organic light emitting display (OLED) or a liquid crystal display (LCD) use large-sized mother glass for convenience in the manufacturing process.[0006]When a flat display device is manufactured, a cassette for accommodating substrates is used to transfer or store a plurality of sheets of mother glass. The cassette accommodates substrates such as a plurality of sheets of m...
