CASSETTE
A cassette for placing a glass substrate, which includes an upper frame, a lower frame the same as the upper frame, and four pillars standing between the upper and lower frames to form asapce. The cassette fabricated structure further includes a plurality of rib racks set up on lateral sides of the upper and lower frames, a plurality of ribs set up on the rib rack, and grooves formed by adjacent ribs for placing the glass substrate.
1. Field of the Invention
The present invention relates to a cassette, and more particularly, to a glass substrate cassette, which can be assembled or disassembled quickly and easily.
2. Description of the Prior Art
The glass substrate plays an important role in the LCD and the PDP panel monitor industry, and has a role similar to the wafer of the semiconductor industry. The glass substrate is delivered several times between different tools during each process in manufacturing.

If the stocker, the rail guided vehicle (RGV), or the automatic guiding vehicle (AGV) are broken, people can still move the 4th or 5th generation vacant cassettes by hand. However, as above mentioned, the weight of the 6th generation vacant cassette is 247 kilograms. It only can be moved by machine vehicles, and people are not able to move the cassette by hand. This causes process delays and the quality of products is influenced. So, how to design a mobile glass substrate cassette for solving this problem is an important topic.
SUMMARY OF THE INVENTIONThe present invention relates to a cassette, and more particularly, to a glass substrate cassette, which can be assembled or disassembled quickly and easily.
The present invention provides a cassette, which comprises an upper frame, a lower frame the same as the upper frame, and four pillars standing between the upper and lower frames to form asapce. The cassette fabricated structure further comprises a plurality of rib racks set up on lateral sides of the upper and lower frames, a plurality of ribs set up on the rib rack, and grooves formed by adjacent ribs for placing the glass substrate.
The weight of the cassette according to the present invention is only a little more than 30 kilograms. Comparing with the 247 kilograms of the 6th generation cassette according to the prior art, the present invention is lighter. The present invention can be assembled or be disassembled quickly and easily, so the mobility increases. When the machine vehicle is broken, the present invention cassette can be moved by people or can be disassembled. So, the present invention can achieve the prior art effect, but has lighter weight and higher mobility.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

The weight of the cassette according to the present invention is only a little more than 30 kilograms. Comparing with the 247 kilograms of the 6th generation cassette according to the prior art, the present invention cassette is lighter. The present invention cassette can be assembled or be disassembled quickly and easily, so the mobility increases. When the machines vehicle is broken, the present invention can be moved by people or can be disassembled. So, the present invention can achieve the prior art effect, but has lighter weight, higher mobility, easier enlargement, easier disassembly, and easier combination.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
