Description

Manufacturing process visualization apparatus and method {Visualization apparatus for manufacturing execution, and method applied to the same}

The present invention relates to an apparatus and method for visualizing a manufacturing process, and more particularly, to an apparatus and method for visualizing a manufacturing process so that anyone can easily grasp the status of the manufacturing process.

In order to understand the flow of the manufacturing process, it is necessary to combine and interpret various information such as operation status information such as equipment operation rate, stoppage, and failure of the production line, product production information, and digitized LOB (Line Of Balancing).

In addition, for the above-described analysis, there is a limitation in that a worker with a lot of experience in the manufacturing process or analysis know-how is required.

Accordingly, there is an attempt to display the manufacturing process in a visible form. There is a Gantt chart that has been traditionally used for process control by representing production plans and performance in a diagram. Recently, as a more advanced form of such a Gantt chart, it is also provided with a configuration that outputs the Gantt chart to a display device.

A Gantt chart is a graph created using two factors: purpose and time. Traditionally, it has been widely used and used for process control in the production process of producing parts through production facilities. This is because there is an advantage in that plans and performances can be simultaneously recorded on a chart and displayed simply and clearly.

However, the Gantt chart has limitations in expressing changes in the manufacturing process, and for this reason, it cannot accurately represent the current state of the process. In addition, since the Gantt chart does not clearly represent the organic relationship between operations, in an inline production method such as the SMT (Surface Mount Technology) process, information on multiple PCB boards in production and the relationship between mutual equipment There are aspects that are difficult to understand.

Furthermore, even beginners can intuitively grasp the status of the manufacturing process without the need to derive it through complex numerical analysis, while providing information on the status of the manufacturing process that is visually displayed with minimized errors to help grasp the approximate status of the process. Instead, it is necessary to have a system that can take active and immediate measures against various situations such as process abnormalities.

The manufacturing process visualization device 100 allows even beginners to intuitively understand the current status of the manufacturing process without the need to derive it through complex numerical analysis, while providing information on the status of the manufacturing process that is visually displayed with minimized errors to roughly It is a configuration that enables active and immediate action against various situations such as process abnormalities, rather than just grasping the current status of the process.

That is, the manufacturing process visualization device 100 may indicate the production status for each of the parts produced on the axis of at least one production facility and time arranged in the manufacturing process line, and the facility, time, production model, operator, It enables users such as workers to intuitively grasp production information, including information on the current status of processes such as warnings and facility shutdowns, in one output screen.

In addition, the manufacturing process visualization device 100 collects a plurality of distributed production status-related information to generate its own analysis or result information, and then converts the finally derived information into graphical information that can be intuitively grasped on the output screen. According to the display, it is possible to understand the production status of the line in real time without analyzing the information from the user's point of view.

This is not only the production manager who can easily grasp the current status of the line site, but also various information on the production status of the manufacturing process line from various work perspectives for the management and support department members who may not have a detailed knowledge of the production status and environment at the line site. This means that it is possible to easily analyze them and easily extract the information they need.

In order to create an output screen that visualizes the process of the manufacturing process line, it is necessary to link the time when the same part is brought in and discharged from each facility on the line. However, there are many cases in which it is not necessary to identify the corresponding part during the line movement process depending on the shape characteristics of the target part to be moved or the situation of the production site.

Marking identification information on each part in the production process may cause a problem of reducing production efficiency or increasing production cost in some cases.

Accordingly, the manufacturing process visualization device 100 according to the present invention has a configuration capable of identifying each part without assigning identification information to the parts moving along the manufacturing process line due to the above problems.

Specifically, the manufacturing process visualization device 100 includes a data receiving unit 110 that receives facility data from at least one production facility in a manufacturing process line, extracts part record information for each part from the received facility data, and extracts the extracted part record information. is classified as corresponding to a specific part movement property of the manufacturing process line, and parts movement information representing a specific part movement property is generated using the result of collecting the classified parts record information, and the part movement information is graphically displayed for each part. It includes a matching execution unit 120 that generates graphic process pattern information of a manufacturing process line, and a screen display unit 130 that displays the generated graphic process pattern information on a screen.

FIG. 2 is a detailed block diagram illustrating the data receiving unit 110 of FIG. 1 in more detail.

As shown in FIG. 2 , the data receiver 110 may include a tool controller module 111 , a data acquisition module 112 , a data classification module 113 , and a database 114 .

The tool controller module 111 is a component for receiving facility data from each production facility arranged in a manufacturing process line, and is preferably provided to correspond to each production facility.

The data acquisition module 112 converts facility data provided from production facilities of different brands into standardized data in that each production facility disposed in the manufacturing process line may be of the same brand, but may include different brands in some cases. It plays a role in processing with

The data classification module 113 may collect standardized data provided from the data acquisition module 112 and may preliminary classify the collected data. For example, the data classification module 113 applies the data provided from the data acquisition module 112 to a predetermined preliminary classification criterion, and can classify data that cannot be interpreted due to errors and data that can be used for production status analysis. .

Data that cannot be interpreted due to the inclusion of errors may not be data that conforms to the aforementioned standardized data format, or may be unreadable data due to part of the data being damaged in the process of data transmission.

Data classified as usable data for analysis of production status from the data classification module 113 is stored in the database 114 .

FIG. 3 is a configuration diagram showing the manufacturing process visualization device 100 of FIG. 1 as an example.

As shown in FIG. 3, the matching execution unit 120 generates graphic process pattern information of the manufacturing process line based on the facility data provided from the data receiver 110, and displays the generated graphic process pattern information on the screen display unit ( 130) to be displayed on the output screen.

In the manufacturing process line, as parts move through the line, they are subjected to a production process that passes through each production facility arranged on the line.

Accordingly, the matching executor 120 serves to mutually match parts groups that are the same part or predicted to be the same part among countless parts passed through for each production facility.

Facility data provided from the production facility includes information on a plurality of parts that are introduced into and discharged from the production facility. For example, the facility data includes first parts record information, which is information about the incoming and outgoing of the first part, second parts record information, which is information about the incoming and outgoing of the second part, and information about the inflow and outflow of the Nth part. It may include Nth parts record information, which is information about what has been discharged.

It is possible not only to check and convert visual information about the parts entering and exiting the production facility, but also to classify the model of each part.

Accordingly, the parts record information may include the input time of the part being introduced into the production facility, the ejection time of the imported part being discharged from the production facility, and the model information of the part.

The matching executor 120 may extract parts record information as described above from facility data provided from production facilities, and classify the extracted parts record information as those corresponding to specific part movement attributes of the manufacturing process line.

Here, the property of moving a specific part of a manufacturing process line means that even if it is the same model, the parts moving in the line can be distinguished, and the specific parts that can be distinguished in this way are sequentially moved through at least one production facility arranged in the manufacturing process line. The time spent in each production facility and the time required to move between production facilities are reflected in the cumulative form of line movement for specific parts that are moved in this way. It contains attributes that can be

That is, the matching executor 120 pre-prepares information on the specific part movement attribute of the manufacturing process line, or classifies the part record information with the result of calculating this information, and uses the result of collecting the specific part movement attribute. Part movement information representing

Part movement properties are information about the movement of parts in an ideal case, such as when a part passes through the line without any problems on the production floor, whereas the above-mentioned part movement information is not an ideal data form, but an actual part moving through the manufacturing process line. It refers to the data formed through each production facility of

FIG. 4 is an exemplary diagram showing a screen structure output by the screen display unit 130 of FIG. 1 as an example.

As shown in Figure 4, the above-described part movement information can be displayed on the output screen. On the output screen, the time the part was brought into the first production facility (A), the time the part was discharged from the first production facility (B), and the difference between the time it was brought in (A) and the time it was discharged (B) 1 Up to the time (C) the part stayed in the production facility can be displayed.

In addition, by reading the slope of the graph for each facility, it is also possible to check the line balance D of the manufacturing process line equipped with these facilities.

5 is an exemplary diagram showing the manufacturing status of production facilities arranged in the manufacturing process line of the present invention as an example, and FIG. 6 is an exemplary diagram in which the matching execution unit 120 of FIG. 1 matches parts as an example. FIG. is an exemplary diagram for explaining a matching rule executed by the matching executor 120 of FIG. 1, and FIG. 8 is an exemplary diagram for explaining another matching rule executed by the matching executor 120 of FIG. 9 is an exemplary diagram for explaining another matching rule executed by the matching executor 120 of FIG. 1 .

As shown in FIG. 5, the number of parts produced and processed in each production facility is different as a result of the parts being not produced and processed through each production facility of the manufacturing process line, but judged as defective or expelled for various reasons.

Accordingly, the matching execution unit 120 has limitations in visually displaying it by tracking the movement of the same part by chronologically connecting the input time and output time of the part based on the facility data provided from each production facility. .

Accordingly, the matching execution unit 120 includes a configuration for tracking the movement of the same part on the manufacturing process line with a minimized error.

When the matching execution unit 120 classifies the extracted parts record information as one corresponding to a specific part movement attribute, at least one time information of entry time and discharge time, movement time between production facilities, time difference information between production facilities, and time difference Whether the information is negative, whether the time lag information is within a predetermined error range for the average of the time lag information, information comparing the number of parts movement lines based on the part movement information and the total number of production facilities, and a part model applied to the manufacturing process line At least one of a change or not and whether the extracted parts record information is final data may be determined as a classification criterion parameter.

Furthermore, when the matching executor 120 classifies the extracted part record information as one corresponding to a specific part movement attribute, it is also possible to further include, as a candidate pool of classification criteria parameters, whether or not production facilities are bypassed.

Through this, the matching execution unit 120 may execute a process combining each of the following logics.

- Connect parts record information in order based on visual information provided from each production facility

- If the time difference between production facilities is a negative number, it is connected to the next part record information

- Skip if it is out of the predetermined error range from the average of the time difference between production facilities

- In the matching result, the last remaining data is skipped

- The number of parts moving lines must be less than or equal to the total number of production facilities

- Skip unprocessed data when changing a part model produced in a manufacturing process line

- Connect the time of the bypassed facility to the time of the immediately preceding facility in time series (i.e., the cycle time is determined to be '0')

The matching execution unit 120 may perform classification that is predicted to be the same part or the same part by combining the above-described logic.

In addition, when information on models and facilities bypassed from production facilities is not provided, the matching executor 120 may execute a process combining the following logics.

- Gather the model names of parts produced by each production facility

- The equipment with the largest number of component models is determined as the reference equipment

- A facility with a smaller part model than the standard equipment is judged as a bypass device

- By comparing the reference equipment and the bypass equipment to specify the bypass model

- After deciding whether or not to bypass and the bypass model for each production facility, based on the determined results, the time of the bypassed facility is time-sequentially connected to the time of the immediately preceding facility (i.e., the cycle time is determined to be '0') being)

Referring to FIG. 7 , the matching execution unit 120 may track the same part for each part model.

For example, as shown in a) of FIG. 7, when the same model and parts matching are ideal without missing parts between the equipment M1 and the equipment M2, each component movement line is determined as a time-series connection.

On the other hand, as shown in b) of FIG. 7, in the facility (M1), the parts of the model A, parts of the model A, parts of the model B, and parts of the model B were sequentially introduced and discharged to produce production, whereas in the facility M2 Parts of model A, parts of model B, parts of model B, and parts of model B are sequentially introduced and discharged, and each parts record information may be provided.

In this case, since the part of the second model A of the facility M1 does not have corresponding part record information in the facility M2 through model information comparison, it can be treated as lost or extracted as defective.

Also, parts of the first B model of equipment M1 are matched to parts of the first B model of equipment M2, and parts of the second B model of equipment M1 are matched to parts of the second B model of equipment M2. can be matched with

In addition, when the third B model of facility M2 is considered only in a matching relationship with facility M1, since there is no related parts record information in facility M1, it can be treated as lost or extracted as defective.

8 and 9, the No. 2 data of the first production facility can be matched with the No. 3 data of the second production facility in chronological order, but the first production facility and the second production facility 3 data of the first production facility can be determined as a matching candidate.

10 is an exemplary diagram showing the configuration of an output screen of the present invention as an example, and FIG. 11 is an exemplary diagram showing the configuration of an output screen of the present invention as another example.

As shown in FIGS. 10 and 11, the matching execution unit 120 includes an axis in which information specifying at least one production facility included in a manufacturing process line is sequentially arranged and a time axis indicating the time when the process has been performed. It creates graphic process pattern information in a form that can be output on the visualization screen.

The screen display unit 130 receives graphic process pattern information in a form that can be output on the process visualization screen from the matching execution unit 120, and displays the provided graphic process pattern information on the screen.

Referring to FIG. 11, the graphic process pattern information includes first graphic information (①) indicating a pattern of parts production, second graphic information (②) indicating a point where parts production was disrupted, and a section where parts production was stopped. It may include third graphic information (③).

The first graphic information (①) supports an intuitive understanding of the LOB and makes it easy to understand the production pattern of the manufacturing process line.

The second graphic information (②) may include cause information and detail information of parts production failure.

To this end, the matching executor 120 may extract facility operation information from facility data of production facilities corresponding to points of the second graphic information (②), and generate the cause information through the extracted facility management information. .

In addition, the matching execution unit 120 can generate the detailed information based on information analysis on the process visualization screen.

12 is a flowchart showing the operation of the manufacturing process visualization device 100 according to the present invention as an example.

The manufacturing process visualization device 100 performs preliminary classification of the facility data received in step S1 into usable data or unavailable data (S3).
