Description

Tracking system of mounting position}

The present invention relates to a mounting point tracking system that recognizes the outline of a PCB and a representative barcode on which a chip module or variant module is mounted, thereby confirming production records of the mounting points of modules mounted on the PCB.

Modules such as chip components or variant components can be mounted on the surface of the PCB through surface mount technology (SMT) equipment. However, even if the same type of component is on the PCB surface, it is different for each vendor, and even for the same vendor, productivity may be different for each reel.

The uniqueness of PCBs produced through surface mount technology equipment is recorded through a representative barcode and stored in a database to record when and how it was produced.

Recently, the reference of modules mounted on a PCB is conducted by searching the representative barcode of the PCB, searching the reference of the mounting point corresponding to each module, and manually finding whether the part was stamped at this location by the operator.

For example, when producing PCBs using surface mount technology equipment, there may be modules that are not inserted into the PCB. In the case of a PCB that has not been inserted like this, the worker brings the PCB to T-studio PC, a process management system, to check the PCB, scans the representative barcode of the PCB using a barcode scanner, or searches for the information obtained by typing the barcode data. You can retrieve information about modules currently mounted on the PCB. In addition, the PCB is searched in T-OLP, a work and process management system for multiple equipment, and the operator visually checks the layout of the PCB to determine which block and which array is not installed. must do it. In order to determine whether it is an equipment error or a post-process error, a separate process must be performed and the following steps must be followed, and there is a problem in that it is not possible to quickly identify the problem due to time delay.

Additionally, the equipment 20 may be equipped to recognize the individual code 11 of the board 10 and then assign a unique production number to each board 10. Accordingly, after the modules 12 are mounted on the board 10, when the individual code 11 of the PCB 10 is recognized, the unique production number of each PCB 10 corresponding thereto is recognized. Information or records of the mounting points of the modules 12 mounted on the PCB 10 can be searched.

In one embodiment of the present invention, the equipment 20 may include SMT equipment for mounting the modules on the board 10.

Additionally, the equipment 20 according to an embodiment of the present invention may be equipped with various software for tracking the mounting point. For example, an RT module 21 for managing access to the board 10 and storing production records, an MMI module 22 for creating a production record file for the board 10, and the above information as well as the above information. An ITS module 23 that stores various production information of the board 10 and information on the modules as well as information on the mounting points of the modules may be provided.

Any configuration requested can be changed or modified as much as desired.

The storage device 30 stores information on the board 10 and modules mounted on the board 10, information on mounting points, etc., and is provided so that the information can be searched according to their information requests.

In one embodiment of the present invention, the storage equipment 30 may include a T-solution 31 (hereinafter referred to as 'T-solution') and a database (hereinafter referred to as 'DB 32'). The T-solution 31 is a configuration that can query the LTS (lots tracking system), that is, a system that tracks and manages the individual code 11 of the board 10 and the corresponding unique production number, and the data The base 32 may be provided as a storage medium in which various information about the individual code 11 of the board 10 and the corresponding unique production number can be stored.

The recognition equipment 40 may include T-mobile 41 and TMS 42. The T-mobile 41 is configured to recognize the appearance of the PCB 10 and the individual code 11 provided on the PCB 10. The T-mobile 41 may be equipped with a wireless terminal, etc., and the T-mobile 41 may be equipped to communicate with the TMS 42, which will be described later, through wireless communication or the like.

The TMS 42 may be equipped to share the DB 32 that stores data collected from the T-solution 31 and the equipment 20. As the TMS (42) communicates with the T-solution (31) and shares the information of the DB (32), the information of the PCB (10) can be recognized through the wired as well as the wireless T-solution (31). As this becomes possible, operator convenience can be improved.

Accordingly, when the PCB 10 is recognized through the T-mobile 41 (the appearance or/and the individual code 11 of the PCB 10), it is recognized according to the individual code 11 of the PCB 10. The stored DB 32 processes various information of the PCB 10 assigned through the unique production number corresponding to the individual code 11, for example, drawing information, mounting point information, etc. of the PCB 10. It becomes possible.

In the configuration described above, first, in the process of producing the PCB 10, information on the mounting points of the modules 12 of the PCB 10 may be stored in the DB 32. Specifically, the board 10 generates a unique production number corresponding to the individual code 11 formed on the board 10 when introduced into the equipment 20, and various modules ( 12) can be installed. That is, the information on the modules mounted on the board 10 through the RT module 21, the MMI module 22, and the ITS module 23 is stored in a storage file corresponding to the unique production number in the DB ( 32).

Additionally, the information stored in the DB (32) can be provided so that the information can be searched through the T-solution (31).

In order to check the mounting point information of the PCB (10) on which the modules are mounted on the board (10) as described above or various information on the PCB (10), the operator uses the T-mobile (41) to check the PCB (10). The outer perimeter of and/or the individual code 11 of the PCB 10 can be scanned. The scan information of the T-mobile 41 can be communicated with the TMS 42 through communication such as wireless Wi-Fi. As the TMS (42) shares the T-solution (31) and the information of the DB (32) stored during production of the PCB (10), various information of the PCB (10) stored in the DB (32), e.g. For example, CAD drawing information and mounting point information of the PCB 10 can be output on a display where the operator can visually check them.

Additionally, when the operator touches, clicks, or selects a desired mounting point among the mounting points displayed on the display, the information on the mounting point is displayed on the display, allowing the operator to check the information on the mounting point.

Hereinafter, the tracking method of the mounting point tracking system 1 having the above configuration can be explained through drawings.

Figure 9 is a diagram schematically showing information output according to selection of an attachment point in the attachment point tracking system 1 according to an embodiment of the present invention. Figure 10 is a flowchart schematically showing the overall process steps of the mounting point tracking system 1 according to an embodiment of the present invention. Figure 11 is a flowchart schematically showing information storage according to the PCB 10 process in the mounting point tracking system 1 according to an embodiment of the present invention.

9 to 11, the location tracking method in the mounting point tracking system 1 according to an embodiment of the present invention includes a unique production number granting step (S10), a recognition step (S20), an output step (S30), and It may include a mounting information provision step (S40).

First, a unique number can be generated through the individual code of the board (the PCB 10 before the modules 12 are mounted is referred to as the 'board 10') (unique number generation step (S10)). .

Specifically, for production of mounting modules 12 on the PCB 10 (corresponding to the 'board 10') before the modules 12 are mounted, the board 10 is equipped with the equipment ( 20) can be entered into the work zone.

At this time, scan operation can be implemented depending on whether there is a need to recognize the individual code of the board 10 (external barcode scan (S11)). In the case of a board 10 that needs to be scanned, when the board 10 is entered into the work zone of the equipment 20, a recognition code (' (corresponding to the individual code (11)') is scanned (PCB representative barcode scan (S12)).

The scan information of the individual code of the board 10 is transmitted to the device (transferring the representative barcode to the device (S13)), and the installation information of the modules mounted on the device can be stored in a file corresponding to the individual code. .

Therefore, the individual code 12 provided on the equipment 20, specifically the board 10 scanned through a separate scanning device, has a unique production number corresponding to the individual code 12 through the above-described software. is assigned (unique production number assignment step (S10)), and the next step, that is, mounting the modules on the board, can be implemented.

Additionally, production information (installation point information) of modules corresponding to the unique production number of the board 10 assigned through the equipment 20 may be applied to the DB 32 and stored. It can be provided to interwork with the T-solution (31) to query information on the PCB (10) stored in the DB (32).

The board 10 for which the scan has been recognized is introduced into the work zone of the equipment 20 (PCB 10 loading (S14)), and various modules 12 can be mounted (production start (S15)). , the PCB 10 whose production has been completed can be discharged from the equipment 20 to complete production (production completion (S16)).

Information on the modules 12 mounted on the board 10 or mounting point information is transmitted to the DB 32 through the equipment 20, and the DB 32 stores a file corresponding to each unique production number. The above information is stored (equipment 20 - DB 32 mounted data transfer (S17)).

As described above, after generating a unique number for each board 10 on which the modules 12 are mounted through the production step of the PCB 10, the modules 12 of the PCB 10 are produced. Information (information on mounting points) can be stored in the DB 32 and can be provided so that information on each mounting point can be tracked and searched.

In order for the worker to check the information (information on mounting points) of the PCB 10 produced after assigning the unique production number, the worker enters the individual code of the PCB through a prepared terminal (herein referred to as 'T-mobile'). can be recognized (recognition step (S20))

Specifically, the worker may implement recognition by scanning or inputting the outer edge of the PCB 10 produced through the T-mobile 41 or/and the individual code 11 of the PCB 10 ( Recognition step (PCB (10) detecting & barcode scanning (S21)).

When the identification code of the PCB (10) is recognized through the T-mobile (41), information on the unique production number corresponding to (linked to) it is retrieved from the stored database (database inquiry (S22)).

The information of the PCB 10 stored in the database can be output to a set display, for example, a computer display, a camera display, or a terminal display (output step S30).

Information read from the database is output to the display according to the outline of the PCB (10) recognized by the T-mobile (41). The PCB (10) information output to the display includes information on the mounting point. It may include a drawing of the shape of the PCB 10, for example, a CAD drawing of the PCB 10.

When the operator selects the desired mounting point on the PCB 10 output to the display, such as by touching or clicking, the information on the corresponding mounting point is displayed on the display to provide mounting information to the worker (mounting information Provision step (S40)).

That is, for example, when an operator selects one mounting point on the PCB 10 output on the display, information on the mounting point, such as reel registration date, reel history, production time, and production line information, is displayed near the selected mounting point. It is displayed on the display and can be checked by the operator.

The information on the installation point may include an error indication of a component with an installation error.

The output information or image of the mounting point can be compared with the stored basic image of the normal mounting point (model image comparison (S31)).

If there is no image in the image comparison step, the output may be terminated, but if there is a problem during image comparison, a defect inspection of the attachment point may be performed.

In addition, in the output step (S30), output can be implemented on a display, but unlike this, it can be provided to provide the shape of the PCB reflected in augmented reality to the operator through an AR device, etc.

If there is no problem with image comparison, if you use a terminal equipped with a display with T-mobile (41), you can output a PCB with image objects for each part through the display, and if you use an AR device, the selected part ( The selected module or selected mounting point all have the same meaning.) AR objects can be output individually (object output (S31)).

Additionally, detailed data on the selected attachment point may be output around the attachment point or in a separate window (LTS output (S41)).

Although embodiments of the present invention have been described with reference to the above and the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features. You will understand that it exists. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
