Abstract
In an automation system, a plurality of machines are connected to a file server via a network and the job result data produced by the machines, are shared by the file server. The job result data processed from a machine (for example, a tester) are stored in the file server. Another machine (for example, a repairer) can execute a job by using the above job result data.
Claims34
An automation system comprising:
- a plurality of machines;
- at least one file sever connected to the machines by a network and stores a job result data on jobs executed by the machines such that the machines may share the job result data, wherein the file server stores the job result data corresponding to all the machines and data summarizing the job result data corresponding to each of the machines;
- a plurality of machine severs respectively connected to the machines and controls the machine connected thereto;
- and
- a host connected to the machine servers by the network, having job information required for the machines and providing the job information to the machine servers,
- wherein the automation system is used in the fabrication of a liquid crystal display.
An automation system of a micro electronic device, comprising:
- a plurality of machines including a tester for testing a substrate with patterns formed thereon, wherein the tester tests the substrate and produces the test result data, which consists of unprocessed raw data and processed summary data;
- at least one file server connected to the machines via a network, storing the job result data on the substrate processed by each machine such that the machines may share the job result data, wherein the file server stores unprocessed raw data corresponding to all the machines and processed summary data corresponding to each of the machines;
- a plurality of machine servers including a tester server, wherein each machine server connects to a corresponding machine and controls the machine connected thereto;
- and
- a host with a database connected to the machine servers via a network, providing the machine servers with job information required for the machines retrieved from the database on the key of an identifier of the substrate, wherein the substrate is a glass.
A method for manufacturing a liquid crystal display (LCD) to control an automation system in an assembly line, comprising the steps of:
- (a) recognizing a work piece loaded in a first machine;
- (b) receiving a job command from a controller to have the first machine execute the work on the work piece;
- (c) reading a first job result data produced from the previous machine and necessary for the first machine, from a file server, wherein the file server connects to a plurality of machines including the first machine on line, and stores the job result data produced from the machines;
- (d) executing a job on the work piece in the first machine by using the first job result data;
- and
- (e) storing a second job result data and data summarizing the second job result data produced in the first machine to the file server, wherein the work piece is a glass.
A method for manufacturing a liquid crystal display (LCD) to control an automation system including a plurality of machines, each performing a job on a substrate, a controller controlling the machines and an automatic guided vehicle (AGV) transferring the substrate to each machine automatically, comprising the steps of:
- (a) loading the substrate to a first machine;
- (b) executing a job on the substrate in the first machine, and storing a first job result data and data summarizing the first job result data produced by the first machine to a file server wherein the file server is connected to the machines and stores job result data and data summarizing the job result data produced by the machines to enable the machines to share the job result data for sharing the first job result data with the machines;
- (c) unloading the substrate from the first machine;
- (d) transferring and loading the substrate to a second machine;
- (e) reading the first job data from the file server before operation of the second machine, executing a job on the substrate in the second machine by using the first job result data produced from the first machine and storing a second job result data to the file server after operation of the second machine;
- and
- (f) unloading the substrate from the second machine, wherein the substrate is a glass.
