Description

TECHNICAL FIELD [0001] The present invention relates to a process management system and a control method thereof,

The present invention relates to a surface mount line bar code missing process tracking management system and a control method therefor. More particularly, the present invention relates to a surface mount line bar code missing process tracking management system and a control method thereof, The present invention relates to a system and method for controlling a missing track of a surface mounted line barcode.

      Generally, the surface mounting line (SMT Line) consists of a production line in which a plurality of processes are installed on one conveyor. In this case, As a result of the miniaturization and high integration, the defective rate is getting higher due to difficulty in the operation, and a production management system for improving the productivity has been increasingly applied.

      To this end, the production management system of the surface mount line, which has recently been applied, is mainly used for the operation and production status of each process, equipment, and various production related statistics of the finished product and for the follow-up management. It is necessary to distinguish a printed circuit board to be put into a production line. In general, a bar code is printed on a printed circuit board.

      However, in the devices used in the above-described surface mounting line, the reader for recognizing a bar code is an optional device, or there are many devices without a reader, and it is difficult to collect production management data for each board A problem occurred.

      1 and 2, the surface mounting line includes a loader device 1, a soldering device 2, a lead application inspection device 3, The first to eighth steps via the chip mount 4, the release mounter 5, the reflow 6, the placement tester 7, and the unloader equipment 8, At this time, in the case of the lead application tester 3 in the third process as the inspection equipment and the packaging tester 7 in the seventh process, since it is an equipment for inspection, a bar code reader capable of reading bar codes is provided However, in the remaining devices, the presence or absence of the device is determined depending on whether the option device is purchased or not. At this time, the production data from each device to the production management system server 9 is transmitted according to the presence or absence of the barcode reader .

      First, if the barcode reader is attached to the corresponding equipment, the barcode for reading the production-related data corresponding to the board is read along with the barcode for distinguishing the printed circuit board for each equipment, and the production management system server 9 .

      In the case where the barcode reader is not attached to the equipment, only the production-related data corresponding to the board currently being produced is transmitted to the production management system server 9 in a state in which the barcode information on the PCB is missing .

      In this case, in order to complete the mounting operation on one printed circuit board, the first to eighth steps as described above must be completed. At this time, the production data generated from the equipments of each process is transmitted to the production management system server 9) should be combined into one piece of information.

      However, as shown in FIG. 2, when the barcode of the printed circuit board on which the corresponding operation is performed can not be read from equipment provided in each process, there arises a problem in collecting production data.

      That is, the first, second, and third boards are sequentially loaded on the boards on which the bar code is printed in the "job 1", and the bar code on the first board is read in the [equipment 1] of the "job 2" After that, the production-related data is transmitted to the production management system server side together with the barcode, and at the same time, the first board is transferred to the next equipment. Then, the first board passes through all the steps of the production line, The production is completed.

      In addition, the [equipment 1] of the 'task 2' carries out the operation of the second board continuously after the first board is transferred to the next equipment. At this time, And the board is removed by the 'job 3' because the failure is not detected in the next process 'job 4', the job for the third board is again performed in the 'job 2' And the third board is transferred to the equipment [2]. If the third board has no problem in all the process operations, the production is completed in the 'operation 6' as the finished product.

      On the other hand, the second board removed through the 'job 3' is inserted into the production line again by 'job 5' after the defect is repaired, and the process is continued until the 'job 6' , The final order of production is the order of the first, second, and third boards, not the first, second, and third boards.

      Also, the production data generated in real time from each equipment and transmitted to the production management system server side is also performed in order of the first, second, and third boards in some equipment, and in addition, 3, and 2 boards.

      Accordingly, all the production data collected by the production management system server need to include all of the barcode information of each board, so that there is no problem in collecting production data for each device of the finalized board. However, Since the bar code reader is not installed in [Equipment 2], bar code information can not be included when the production data is transmitted to the production management system server. Therefore, As the production data is transmitted in the order of the first, third, and second boards without being judged, the difference from the first, second, and third order of the boards transmitted in the 'task 2' occurs.

      Therefore, in the actual surface mounting line in which the equipment on which the bar code reader is mounted and the equipment on which the bar code reader is not mounted are mixed, it is impossible to anticipate which process the board will be removed from. In addition, There is a problem that it is impossible to integrate and manage the production data generated and transmitted in real time in each equipment to the same board, There is a problem that the data to be managed and reused for improving the productivity in the mobile communication system must be limited.
