ABSTRACT:
CLAIM OF PRIORITY
This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application for Computer Manufacturing System earlier filed in the Korean Industrial Property Office on Apr. 30, 1998 and there duly assigned Serial No. 98-15569.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a computer manufacturing system, and more particularly, to a computer manufacturing system to improve its flexibility for small amount of production for various types of items by changing the production line for assembling, aging, testing, and packaging computer bodies into unit cell structure.
Related Art
Production lines including, testing and packaging have been used for production of computers. Typically, most production lines for assembling, aging, testing and packaging are designed and arranged for mass production of a product such as computer. Computers used in almost all industrial fields are becoming more and more diversified. To comply with the recent demands, the computer production lines have to be changed to increase value-added productivity with the production conception compatible with multi-itemized production in small amounts.
A personal computer is made by assembling a monitor, a body, and various auxiliary equipments into one set, and in the computer body, various disk drives, boards, or power suppliers, etc. are assembled by option. The various disk drives assembled in the computer body may include a hard disk drive, a floppy disk drive, or a compact disk. The various boards may include a main board, a video board, or a sound board, etc.
The conventional computer manufacturing system is a mass production system for a specific model. Processes are specialized and divided. A large number of personnel are displaced on each diversified process. A manufacturing system for the mass production for one single item requires large investment.
However, recently, the environment for computer business markets has been changed because of various computer items and shortened life time of each item, etc. Therefore, the conventional mass production system established by large investment cannot be effectively adapted to the rapidly-changing market environment, and the productivity and efficiency are deteriorated in spite of the investment.
Also, the conventional mass production system cannot be appropriately applied for small amount production per model of multiple items. Also, it is difficult to keep balance of the outputs for each unit process. A partial operation stop often occurs thereby causing lots of time for the whole production processes for one item.
In addition, the conventional mass production system needs scores of operators for the diversified processes, and the sufficient quality verification is difficult to guarantee because of maintenance of a separate test process, and operators cannot take an action quickly and promptly on operations because they work seated on the chairs.
SUMMARY OF THE INVENTION
The present invention is directed to provide a cell line structure for allowing small amount of production for a specific item.
Another object of the present invention is to establish the conformity to the multiple items production by employing plurality of cell lines and overcoming the limit of the life time per model.
A further object of the present invention is to make manufacturing lines for computer body into cell line of system ways, and allow easy replacement of the apparatuses installed in the cell lines.
A still further object of the present invention is to increase the operation efficiency by making operators commonly or assistantly perform the jobs in other areas, and do the jobs standing.
A still another object of the present invention is to easily keep balances for outputs from respective unit process, and prevent the stop of the production flows thereby reducing the production time in outputting products.
A still another object of the present invention is to make quality assurance for products possible by performing test in unit cell line.
To achieve these and other advantages and in accordance with the purpose of the present invention as embodied and broadly described, the computer manufacturing system comprise an assembly unit wherein various assembly parts are assembled into a main chassis according to a process order to complete the assembly of a computer body, an aging and test unit for testing and checking the performance of the computer body transferred from the assembly unit, and a package unit for packaging the computer body transferred from the aging and test unit, the assembly unit, the aging and test unit, and the package unit sequentially aligned in accordance with process sequences, and the assembly unit and the package unit being aligned to the opposite facing each other.
The work place for the assembly unit and the work place for the package unit are preferably shared.
In addition, the assembly unit may comprise a preassembly unit in which brackets are assembled with the assembly parts including various disk drives, and a main assembly unit in which the assembly parts transferred from the preassembly unit and other parts are assembled into the main chassis, and a cover is put into the main chassis to complete the assembly of the computer body, the main assembly unit being preferably connected with the preassembly unit with sequentially aligned.
A car may be further provided on the main assembly unit to move the main chassis from a certain location thereto, the car being displaced in a certain space between the preassembly unit and the main assembly unit.
The preassembly unit may comprise a first work section for performing a preassembly job, and a receipt section contacted with the first work section to supply parts to be preassembled. Also, a hard disk copy may be displaced on one side of the first work section to copy hard disk drives to be preassembled. in addition, a carrier including a transfer box may be provided on one side of the first work section, and the carrier reciprocally moves between the preassembly unit and the main assembly unit.
In addition, the receipt section may be constructed as a upper layer and a lower layer, wherein parts to be assembled are supplied via the upper layer with contained inside a box, and an empty box is collected from the other layer, a lower layer, either one of the above two layers, the upper layer and the lower layer, being slanted toward the first work section, the other layer being slanted toward its opposite side.
The main assembly unit may comprise a second work section in which a main assembly job is performed, and a second receipt section to supply parts to be assembled, a transfer means being installed on the upper side of the second work section to transfer a main sushi, and also, a supplementary plate having a plurality of ball bearings provided thereon may be assistantly used.
The aging and test unit may comprise at least one aging car to load plurality of computers assembled in the assembly units, and aging is performed by a predetermined test program in the aging car.
The aging car performs the aging, and moves into one direction by a guide rail provided thereon. While the aging car moves into one direction along with the guide rail, the aging and test unit further comprises a first moving means for automatically moving the computer body assembly-completed in the assembly units to the aging and test unit, and preferably, a test section having at least one monitor displaced with a certain height for checking the aging result for the aging-completed computer body.
The aging and test unit may further comprises a buffer car for temporarily storing the test-completed computer bodies, and a second moving means for moving the computer body loaded in the buffer car for package. The second moving means comprises a second transfer frame to move up/down within frames to move the computer body in the buffer car for package.
The package unit may comprise at least one vacuum absorber, a driving means f
