A data managing system for a workpiece production line comprising a plurality of assembly lines connecting sequentially to the next line, each assembly line comprising:
- an assembly pallet for mounting thereon a workpiece, said assembly pallet comprising a data storage means;
- a parts supplying station where a workpiece conveyed from outside is mounted on said assembly pallet;
- at least one process station where the workpiece mounted on said assembly pallet is processed;
- at least one inspection station where the processed workpiece is measured, said inspection station comprising means for reading and writing data of a measurement in said data storage means of said assembly pallet;
- a workpiece removing station where the workpiece is removed from said assembly pallet and mounted on a conveying pallet for conveying the workpiece to the next assembly line, said conveying pallet comprising data storage means, said workpiece removing station comprising means for transferring said measurement data stored in said data storage means of said assembly pallet to said data storage means of said conveying pallet.
A method for managing data for a work production line comprising a plurality of assembly lines connected sequentially to the next line, comprising steps of:
- mounting at least one workpiece on an assembly pallet having a data storage member;
- processing the workpiece mounted on said assembly pallet;
- inspecting the processed workpiece;
- writing data of the result of said inspection in said data storage member of said assembly pallet;
- removing the workpiece from said assembly pallet and mounting the same workpiece on a conveying pallet having a data storage member for conveying the workpiece to the next assembly line while transferring the data stored in said data storage member of said assembly pallet to said data storage member of said conveying pallet;
- transferring data stored in said data storage member of said conveying pallet to a storage member of a new assembly pallet in the second assembly line.
