A manufacturing process of a flat display made up of such a number of unit processes can be generally performed in a clean room.

A large number of substrates, which have been processed by specific process equipment inside the clean room, are loaded on a cassette and then transferred to another process equipment in the clean room by an AGV (Automatic Guided Vehicle). Here, a plurality of stockers are arranged in the clean room in order to temporarily store the substrates loaded on the cassettes or the process is already performed in other process equipments.

And overhead shuttles (OHS) can generally be used when it is necessary to transport cassettes from a stocker to another stocker.

I will discuss this in detail. Typical flat display process lines include a variety of process equipment required for each process, a plurality of stalkers for storing cassettes loaded with substrates to be supplied to the process equipment, an overhead shuttle for transferring the cassettes from the stalker to other stalkers, And a running rail for guiding the head shuttle.

That is, each process equipment is disposed in the vicinity of each stocker, and performs each process using a substrate mounted on a cassette provided from a stocker. Substrates that have undergone each process are then loaded onto cassettes and stored in the stocker. At this time, an overhead shuttle is used for transferring the cassette to the process equipment or transferring the cassette from the process equipment to the stocker. The overhead shuttle is for transporting the cassette to a plurality of stockers arranged so as to be spaced apart from each other in the clean room.

A cassette transfer apparatus using an overhead shuttle is provided with a transfer carriage for transferring a cassette while moving along a running rail provided on a ceiling, a loading port for temporarily storing a cassette carried by the carriage, and a cassette placed on the loading port (P & P) for transferring to a bogie.

The conveyance truck used for such equipment operation can carry a conveyed article, that is, a cassette, a mask, or the like on which the above-described substrate or substrate is mounted, by carrying one rail through a predetermined control.

Therefore, the sensors for determining the position of the conveying carts and the parts related thereto must be mounted at the same position without any error so that all of the conveying carts can be moved along one rail to return the conveyed articles to a desired process.

In order to set the sensors (detectors) and their associated parts on the conveying carriage without any error, a suitable jig is required. This is called a conveying carriage alignment station. When the conveyance carriage arrives at the conveyance carriage alignment station and is seated in the correct position, the sensor for determining the position of the conveyance carriage and its associated parts can be set.

On the other hand, there can be many kinds of conveyance trucks being applied in the process, and in particular, they can be largely divided into a mask type conveyance truck and a glass type conveyance truck. Since these conveying bogies have different types and sizes of conveyed articles to be conveyed, individual conveyance bogie aligning stations are required.

That is, since the sensor direction reference providing section 242 serves as a reference for providing the position and direction in which the sensor module 440a is to be fixed, the sensor direction reference providing section 242 is provided for the sensor module 440a installed in each of the plurality of carrier bins 400, When the position and direction are aligned and fixed based on the direction reference providing portion 242, the accurate position or direction of the sensor module 440a can be aligned.

The sensor module 440b of the transport bogie 400 may include a bar code portion 443 inclined toward the traveling rail. In this case, the bar code portion 443 reads the bar code displayed on the traveling rail. . The position adjusting jig 240b for the sensor module can be disposed below the bar code part 443b so that the position and direction of the bar code part 443 can be adjusted.

16, the position-adjusting jig 240b for the sensor module may include a sensor-engaging protrusion 243 and a reference-providing inclined portion 244. [ The sensor protrusion 243 is coupled to the common jig 200 for setting and protruding toward the barcode portion 443 so that the barcode portion 443 can be positioned close to the reference inclined portion 244 Can be protruded up to a height. The reference providing inclined portion 244 extends from the sensor engaging projection 243 and is provided so as to form an inclination corresponding to the inclination formed on the bar code portion 443. [

The accuracy of sensing may be improved when the bar code portion 443 provided on the conveyance carriage 400 is inclined at a predetermined angle toward the running rail, so that the bar code portion 443 is formed in the conveyance carriage 400. However, if the bar code of the running rail can be read, the bar code part 443 may be provided so as to face the driving rail in a direction perpendicular to the driving rail.

Here, the bar code portions 443 provided on each of the plurality of conveyance bogie 400 should be coupled to the conveyance bogie 400 so as to have a constant inclination. However, since the position and direction of the bar code portion 443 are initially aligned The inclination of the bar code part 443 is not inclined at an accurate angle to read the bar code of the running rail.

Since the reference inclination portion 244 is fixed in a state where the inclination is formed, the bar code portion 443 provided on the conveyance carriage 400 is brought into contact with the reference inclination portion 244 finely, When the bar code unit 443 is fixed so as to have the same inclination as the inclination of the reference providing slope unit 244, the bar code unit 443 is positioned at the correct position Direction. However, since the glass can be coupled to the front surface of the bar code part 443, it is necessary to take care that the glass is damaged when the bar code part 443 is finely brought into contact with the reference inclined part 244.

As described above, in the present embodiment, the mask type conveyance cart setting jig unit 310 and the glass type conveyance cart setting jig unit 320 are detachably coupled to one setting common jig 200 Therefore, the parts setting operation can be carried out commonly for the conveyance bogies of different types without having to provide individual stations as in the past.

Since the positioning jig 230 for the center plate and the positioning jig 240 for the sensor module are applied to the common jig 200 for setting the center plate 430 and the sensor module 440 Can be easily adjusted.

According to the present embodiment having the structure and operation as described above, the parts setting operation can be commonly performed for the conveyance bogies of different types without having to provide separate stations as in the past. As a result, Of course, reduce the foot print of the equipment, among other things.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. It is therefore intended that such modifications or alterations be within the scope of the claims appended hereto.
