Description

Selective input system of workpiece and control method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective input system of a workpiece and a control method thereof, and more particularly, to a manufacturing process such as a semiconductor or a thin film transistor liquid crystal display (hereinafter referred to as TFT-LCD). The present invention relates to a system for selectively inserting a workpiece to be used into a facility and a control method thereof.

Hereinafter, a selective input system of a conventional work object and a control method thereof will be described, taking as an example a washing machine installation in a TFT-LCD manufacturing process.

Unlike the general process equipment in the TFT-LCD manufacturing process, the scrubber equipment has a storage unit (hereinafter referred to as 'L-SUPPORT') in the loader section, whereby the work object (hereinafter referred to as 'glass') is fixed. Each unit, for example, 10 sheets are loaded into the washing machine. In addition, the worker configures the desired number of glasses in a work set unit (hereinafter referred to as 'LOT'), and the number of L-SUPPORT used in the loader unit is determined accordingly. For example, if the L-SUPPORT is 10 sheets, one L-SUPPORT is used when the number of glasses desired by the worker is 10 sheets or less, and two L-SUPPORTs are used when the L-SUPPORT is 10 sheets or more. At this time, when the worker configures the glass to proceed in the scrubber equipment to LOT should be of the same type of glass.

Therefore, when an operator configures LOT of different kinds of glasses in the scrubber facility, there is a problem that such a process cannot be performed in the conventional scrubber facility. In addition, as described above, when it is necessary to process several kinds of glass in the washing machine, there is a hassle of having to separately separate the glass of the same type and proceed with the washing operation separately. In addition, there is a problem that the unloader of the scrubber equipment needs to generate a LOTID according to the desired LOT configuration.

An object of the present invention is to solve such a problem, by attaching a barcode reader to the washer equipment and automatically determining the type of glass to be loaded, and remotely configuring the corresponding LOT configuration to select a work object accordingly. The present invention provides an input system and a control method thereof.

With reference to the drawings will be described with respect to the selective input system of the workpiece and the control method thereof according to the present invention.

1 is a block diagram showing the configuration of a system for selective input of a workpiece according to an embodiment of the present invention.

As shown in FIG. 1, the facility 300 is connected to the facility server 200, and the facility server 200, the host 100, and the user interface 400 are connected to a network. Therefore, when the glass is loaded by the L-SUPPORT in the facility 300, the barcode reader in the L-SUPPORT reads the ID of the loaded glass and automatically reports it to the facility server 200. In addition, the facility server 200 selects a LOT corresponding to the glass loaded from the LOT table 110 in the host according to the received information and transmits the LOT to the facility 300. Therefore, the facility 300 automatically performs work on the loaded glass in various ways according to the selected LOT.

FIG. 2 is a detailed block diagram of the equipment shown in FIG.

FIG. 2 illustrates a cleaner 300 used in a manufacturing process of a liquid crystal display, which includes a loader 310, a cleaner 320, and an unloader 330. Here, the loader 310 has two L-SUPPORT (312, 314), each of the L-SUPPORT (312, 314) loads 10 glasses, L-SUPPORT (312, 314) is a bar code respectively Readers 312B and 314B. Accordingly, the barcode readers 312B and 314B automatically read the IDs of the glasses loaded by the L-SUPPORTs 312 and 314. In addition, the cleaning unit 320 is a place where the cleaning operation is actually performed on the glass that is loaded, the unloader unit 330 has two ports 332 and 334, and the empty cassette is loaded therein, and the glass has been cleaned. Is kept here.

Hereinafter, an operation in which a scrubber facility is connected to the system and automatically selects and inserts a workpiece.

FIG. 3 is a first process flow chart in the selective input system of the workpiece shown in FIG. 1, wherein the number of L-SUPPORTs of the scrubber is 10 sheets, and the scrubber facility of FIG. 3 has 1 L-SUPPORT 1 ~. 10 sheets can be processed.

As shown in FIG. 3, the operator determines whether the loader of the washing machine facility is empty (S100), and if the loader is empty, configures the LOT for the glasses to be worked on and registers it in the LOT table (S105). If the loader is not empty, wait until it is empty. Here, the items registered in the LOT table are information such as the LOTID, the type of glass, and the number of sheets. Next, after the operator registers the new LOT configuration in the LOT table through the operator screen, the L-SUPPORT including the glass to be worked on is loaded into the loader unit (S110). At this time, the L-SUPPORT has a barcode reader to read the ID of the glass to be loaded, and then determine whether the read ID is normal (S115). Next, when the cleaner equipment reads the ID normally, the barcode reader completes the L-SUPPORT load and reports it to the cleaner equipment server (S125). In addition, when the barcode reader does not read the ID normally, the cleaner equipment calls the operator and the operator directly inputs the glass ID using the keyboard (S120), and reports that the L-SUPPORT load is completed to the cleaner equipment server ( S125).

On the other hand, the washing machine installation server queries the LOT that can proceed in the LOT table with the received glass ID (S130). At this time, if the inquiry is successful, it is determined whether each port of the unloader has an empty cassette for storing the glass in which the cleaning operation is completed (S140). In addition, if the inquiry fails, the worker is called and reported to the scrubber facility server by the worker (S135), and then starts again from the step (S105) of registering the LOT to be currently worked by the worker in the LOT table.

In the above-described determination step (S140), if the empty cassette is loaded in the unloader, the washing machine installation server automatically drives the washing machine facility (S150), and if the empty cassette is not loaded in the unloader, the washing machine installation server first unloads it. After the empty cassette is loaded (S145), the washing machine is driven (S150).

In the above, the washing machine installation demonstrated the method of processing 1-10 sheets of glass using one L-SUPPORT. As a result, FIG. 3 shows that the number of glasses required by the cassette at each port located in the unloader section of the cleaner unit is registered by the operator as LOT in the LOT table, and the loader section automatically remotely proceeds by the designated number accordingly. To construct a lot. In addition, when the worker has a lot of glass number specified when the lot is configured, the washing machine is driven. If the worker does not have the glass when configuring the LOT, it does not process and loads new glass continuously until the glass is loaded by L-SUPPORT.

Hereinafter, a description will be given of how the scrubber facility processes 11-20 sheets of glass with two L-SUPPORTs.

FIG. 4 is a second processing flowchart in the selective input system of the workpiece shown in FIG.

As shown in Fig. 4, it is determined whether the loader of the washing machine facility is empty (S200). If the loader is empty, the worker registers the LOT to be worked on in the LOT table in the host (S205), and the loader is empty. If not, wait until it is empty. Here, the matters registered in the LOT table are the same as those described with reference to FIG. 3. Next, after the worker registers the new LOT in the LOT table through the operator screen, the L-SUPPORT including the glass to be worked on is loaded (S210). Here, there are 1 to 10 glasses in the first L-SUPPORT. In addition, the L-SUPPORT has a barcode reader, and after reading the ID of the glass to be loaded, it is determined whether the read ID is normal (S215). Next, when the cleaner equipment reads the ID normally, the barcode reader completes the first L-SUPPORT load and reports it to the cleaner equipment server (S225). In addition, when the barcode reader does not read the ID normally, the cleaner equipment calls the operator and the operator directly inputs the glass ID using the keyboard (S220), and reports that the L-SUPPORT load is completed to the cleaner equipment server ( S225).

The scrubber facility server inquires the LOT which can proceed in the LOT table with the received glass ID (S230). At this time, if the inquiry is successful, the second L-SUPPORT is loaded again in the second port of the loader (S240). Here, there are 11 to 20 glasses in the second L-SUPPORT. In addition, the bar code reader of the second L-SUPPORT reads the ID of the loaded glass, and then determines whether the read ID is normal (S245). Next, when the cleaner equipment reads the ID normally, the barcode reader completes the second L-SUPPORT load and reports it to the cleaner equipment server (S255). In addition, if the barcode reader does not read the ID normally, the scrubber equipment calls the operator and the operator directly inputs the glass ID using the keyboard (S250), and reports that the second L-SUPPORT load is completed to the scrubber equipment server. (S255).

Next, the scrubber facility server checks the type of glass based on the received glass ID in the first L-SUPPORT and the second L-SUPPORT (S260). Here, when the types of glasses in the first L-SUPPORT and the second L-SUPPORT are not the same, first, the glass in the first L-SUPPORT is driven first and the worker is notified. Next, after the glass of the first L-SUPPORT is processed, the same kind of glass may be reloaded by the first L-SUPPORT to re-run the insufficient number of sheets. In addition, when the types of glasses in the first L-SUPPORT and the second L-SUPPORT are the same, all the glasses are loaded by the first L-SUPPORT and the second L-SUPPORT and then driven simultaneously. Here, the latter case will be described with reference to FIG. Therefore, when the same glass is loaded by the first L-SUPPORT and the second L-SUPPORT, it is determined whether each port of the unloader has an empty cassette for storing the glass in which cleaning is completed (S270). Call (S265).

In the above-described determination step (S270), if an empty cassette is loaded in the unloader, the cleaner apparatus automatically drives the cleaner apparatus (S280), and if the empty cassette is not loaded in the unloader, the cleaner apparatus server first unloaders. After the empty cassette is loaded (S275), the cleaner unit is driven (S280).

In the above, the washing machine installation demonstrated the method of processing 11-20 sheets of glass using two L-SUPPORTs. Here, if unwanted glass is loaded in each L-SUPPORT of the loader during LOT configuration, all L-SUPPORTs may be stopped and the type of glass required for LOT configuration may be requested. In addition, it can find the most suitable LOT among the LOT information registered in the LOT table according to the load status of the current L-SUPPORT and automatically run it.In accordance with the loaded state, the operator configures and registers a new LOT in the LOT table through the operator screen. You can also

Hereinafter, the method of advanced from the loaded glass in the state where the number of sheets less than the number of glasses required at the time of a LOT structure at the loader part of a washing | cleaning apparatus is loaded first is demonstrated.

FIG. 5 is a third process flowchart in the selective input system of the workpiece shown in FIG.

As shown in Fig. 5, it is determined whether the loader of the scrubber facility is empty (S300). If the loader is empty, the worker registers the LOT to be worked on in the LOT table in the host (S305), and the loader is empty. If not, wait until it is empty. Here, the matters registered in the LOT table are the same as those described in FIG. Next, after the worker registers the new LOT in the LOT table through the operator screen, the L-SUPPORT including the glass to be worked on is loaded. At this time, since the L-SUPPORT occupies one port of the loader, first, the first L-SUPPORT is loaded into the first port of the loader (S310). Further, after reading the ID of the glass in which the barcode reader inside the L-SUPPORT is loaded, it is determined whether the read ID is normal (S315). Next, when the cleaner equipment reads the ID normally, the barcode reader completes the first L-SUPPORT load and reports it to the cleaner equipment server (S325). In addition, if the barcode reader does not read the ID normally, the cleaner equipment calls the operator and the operator directly inputs the glass ID using the keyboard (S320), and reports that the L-SUPPORT load is completed to the cleaner equipment server ( S325).

The scrubber facility server inquires the LOT which can proceed in the LOT table with the received glass ID (S330). At this time, if the information registered in the LOT table and the information of the loaded glass is matched, it is determined whether there is an empty cassette in the unloader of the cleaner even if the number of sheets is small (S340). On the other hand, if the inquiry fails, the operator is called and reports that the inquiry failed by the worker to the scrubber facility server (S335) and starts again from the step (S305) of registering the LOT to be currently worked by the worker in the LOT table.

In the above-described determination step (S340), if the empty cassette is loaded in the unloader, the cleaner apparatus server automatically drives the cleaner apparatus to process the glass loaded by the first L-SUPPORT (S350), If the empty cassette is not loaded, the scrubber facility server first loads the empty cassette into the unloader (S345) and then drives the scrubber facility (S350).

Next, the second L-SUPPORT is loaded into the second port (S355), and it is again determined whether the ID read by the barcode reader is normal (S360). In the determination process (S360), if the ID is normal, the washer facility reports to the washer facility server that the second L-SUPPORT is loaded in the second port, and if the ID is not normal, call the worker and enter the ID directly (S365). ).

On the other hand, the scrubber facility checks the type of glass of the first port and the second port, and if the same, requests the scrubber facility server permission to work on the glass loaded in the second port (S380). Next, when the work on the glass loaded in the first port is completed (S385), the scrubber facility requests to unload the cassette of the first port (S390), and the scrubber facility server receiving the same may request L-SUPPORT of the second port. In order to drive the scrubber facility (S395).

If the glass type of the first port and the second port is not the same in step S375, the L-SUPPORT of the second port is treated as a failure (S405), and the L-SUPPORT loaded in the second port is unloaded (S410). ). In addition, a new cassette is requested to be loaded by the L-SUPPORT in the second port, and when the L-SUPPORT is loaded in the second port, the process is performed again from the step S360.

In the above, the worker advanced in the state where the number of glasses in the loader section is insufficient compared to the number of sheets specified in the lot configuration, and explained how to re-run only the number of sheets after the remaining number of the same type is loaded. In addition, when different kinds of glass are loaded in the loader section of the washing machine, after advancement of the kinds of glass necessary for the LOT configuration, the other kinds of glass are stopped. It loads the same type of glass into the port that is currently in progress, and then restarts the number of copies. Finally, if different types of glass are loaded in the loader, advance the type of glass necessary for LOT configuration, and when the operation is completed on the corresponding port, reload the same type of glass on the corresponding port Re-drive as much as possible to construct LOT.

An embodiment of the present invention describes various systems for selecting a work object loaded in a specific unit in a loader unit by using a washing machine as an example, first registering it in the LOT table, advancing according to each ID, or performing a separate work process. However, it is not limited thereto. In addition, all the methods mentioned herein are not limited to the above mentioned matters.

In addition, although the embodiment of the present invention has been described using the manufacture of a TFT-LCD as an example, the present invention is not limited to the manufacturing of the above-described TFT-LCD, and all industrial fields in which only a workpiece is selected and processed, such as a plasma display panel. Can be applied in

As described above, according to the present invention, by reading the ID of the glass loaded with a barcode reader in the loader part of the facility and transmits it, the facility server inquires the LOT table accordingly and selects the appropriate LOT information to drive the facility. The facility can automatically handle several types of workpieces and can run the new types of workpieces without operator intervention.

Stage 1; A second step of loading a first workpiece into the loader by the first accommodating unit and reading an ID of the first workpiece to determine whether it is normal; In the second step, when the ID of the first workpiece is normally read, completing the loading of the first workpiece and reporting it to the facility server; In the second step, if the ID of the first work object is not normally read, call the worker to directly enter the ID of the work object, and then reporting to the installation server that the loading of the first work object is completed step; A fifth step of the facility server inquiring the corresponding workset information from the database with the ID of the first work object; In the fifth step, if the inquiry is successful, it is determined whether there is an empty cassette in the unloader to store the finished work object, and if the inquiry fails, the operator is called and the operator reports it to the facility server and then the A sixth step of starting from step 1 again; In the sixth step, the facility is automatically driven for the first workpiece when the empty cassette is loaded in the unloader, and if the empty cassette is not loaded in the unloader, the unloader is first loaded on the unloader. A seventh step of driving the facility after the empty cassette is loaded; An eighth step of loading a second workpiece into the loader by the second accommodating unit and reading an ID of the second workpiece to determine whether it is normal; In the eighth step, when the ID of the second workpiece is normally read, completing the loading of the second workpiece and reporting it to the facility server; In the eighth step, if the ID of the second workpiece is not normally read, the operator calls the operator to directly input the ID of the workpiece, and then reports to the installation server that the loading of the second workpiece is completed. step; An eleventh step of the facility server checking the type of the first and second workpieces with the IDs of the first and second workpieces; In the eleventh step, the facility is driven for the second workpiece after the work on the first workpiece is completed when the types of the first and second workpieces are the same; And a twelfth step of treating the work of the work object as a failure and starting again from the seventh step. The method of claim 20, The seven steps, The work is advanced for the first work object even when the number of the first work objects in the first storage unit is insufficient compared to the number of work objects specified in the work set information, and the remaining work of the same type is performed. Control method of the selective input system of the workpiece, characterized in that the re-drive after the number of objects loaded. The method of claim 20, The seventh step, When different types of workpieces are loaded in the first and second accommodating parts, the first workpiece required for the workset information is advanced and the second workpiece not necessary for the workset information is stopped. And loading the workpiece of the same type as the first workpiece, and re-driving as much as the number of sheets insufficient to re-drive the workpiece. The method of claim 20, The seventh step, When different kinds of workpieces are loaded into the first and second accommodating units, the first workpieces required for the workpiece assembly information are advanced, and when the work on the first workpieces is completed, The control method of the selective input system of the workpiece, characterized in that for reloading the object of the same type to the first storage unit by the number of insufficient. The method of claim 20, The information registered in the database is a work set ID, the type and number of work objects control method of the selective input system of the work object. The method of claim 20, And the receiving part has a barcode reader for reading the ID of the workpiece to be loaded. The method of claim 20, The control method of the selective input system of the work object, characterized in that the work unit does not process the work on the work object when the work set information for the work object loaded in the loader is not registered in the database. . The method of claim 20, And a worker directly registers the workset information corresponding to the cassette in the unloader section in a database. The method of claim 20, And said facility is a scrubber facility in a liquid crystal display manufacturing process.
