Next, an embodiment of the present invention will be described. FIG. 2 is a configuration diagram of the manufacturing management system according to the embodiment of the present invention. The manufacturing management system 1 according to the present embodiment includes:
The storage unit 12, the distribution unit 13, and the warning unit 14 of FIG.
Is provided. Details of the server 21 will be described later.

In the manufacturing management system 1, a plurality of terminals 22 are distributed and installed for each of a plurality of types of functional departments. In FIG. 2, as an example of the functional department, the equipment maintenance management department,
Although a process technology management department, a quality management department, a manufacturing department, and a production management department are shown, this is not a limitation of the present invention and may, for example, have additional functional departments. The terminals installed in each functional section are, for example, computer terminals, and the number is arbitrary.

Such functional sections and terminals 22 do not always exist in the same room, the same floor, the same factory, or the like. Each terminal 22 is connected to the server 21 via a line. This line is preferably a dedicated line such as an optical fiber in consideration of data capacity or data transfer speed, but may be a public line or a wireless line.

A control sequencer 23 for controlling the processing apparatus is connected to each processing apparatus in each manufacturing process. The control sequencer 23 is connected to the server 21 via a computer 24 attached to a processing device. Normally, the processing device-attached computer 24 stores information (referred to as "recipe information") on set processing conditions for manufacturing a target product in the manufacturing process.

The recipe information includes, for example, set values for each manufacturing process or each product such as a set temperature, a set voltage value, and a set time, and component information of each material. This recipe information is stored in the computer 24 attached to the processing device.
To the control sequencer 23 to cause the processing apparatus to produce the target product. Further, the control sequencer 23 monitors the operation state of the processing device,
As the information on the production results in the production process, it is possible to acquire the actual values such as the actual temperature, the actual voltage, the actual time or the actual number, and the actual analysis values analyzed by the automatic analyzer. Further, it is also possible to detect information relating to various abnormalities, such as equipment abnormalities relating to the manufacturing apparatus and process abnormalities that deviate from desired production results. Note that the actual value may be manually analyzed, and the analysis value at this time may be linked to time.

In this embodiment, the detecting means 11 shown in FIG.
, A control sequencer 23 and a computer 24 attached to the processing device. Various input devices (not shown) are connected to the control sequencer 23. For example,
In the case of temperature, a resistance thermometer pair, a thermocouple, a temperature controller and the like are used. In the case of pressure, a pressure sensor or the like is used. Outputs of these input devices are input to the control sequence 23. The information on the manufacturing results and abnormalities in the process, which is acquired by the control sequencer 23, is transmitted to the server 21 via the computer 24 attached to the processing device.

The storage means 12 in the server 21 accumulates information relating to the production results and abnormalities detected by the detection means 11 and forms a database. As the process progresses in the manufacturing process, information on the manufacturing results and abnormalities detected by the detecting means 11 is provided for each product in a predetermined data format together with the manufacturing date and time, manufacturing lot number, processing device number, recipe information, and the like. It is linked with.

The stored information is distributed by the distribution means 13 in the server 21 to the terminals 22 of the respective functional sections.
The number and types of information stored in the storage unit 12 in the server 21 are enormous. The distribution means 13 in the server 21
Each of the enormous numbers and types of information accumulated is stored in each terminal 2.
3, but it is more preferable that only the information desired by the user of the terminal can be extracted from the vast amount of information. In other words, the content of information that is generally desired to be distributed differs for each functional department or for each terminal user,
For example, by customizing and presetting information to be delivered to a terminal for each functional section or for each terminal, the manufacturing process can be grasped and managed more efficiently. This setting content is stored in the storage device in the terminal 22 or the server 21.

As described above, in the present embodiment, various types of information are linked in a predetermined data format and stored in a database, and only necessary information can be extracted in response to a request from the terminal. The user can select the production lot number, the production date and time of the product, the processing device number, recipe information, the production result value,
Alternatively, it is possible to search for desired information out of the presence or absence or type of abnormality by referring to the past history.
For example, from each terminal, it is possible to search for a production result value from a production lot number or to search for an abnormality at a specific date and time. Alternatively, various types of information may be displayed in a list based on predetermined items.

The warning means 14 in the server 21 shown in FIG. 2 transmits warning information to at least one terminal when the detecting means 11 detects information on an abnormality. Note that the information regarding the abnormality is also stored in the storage unit 12 in the server 21. Therefore, as described above, the user can also search for the information regarding the abnormality retrospectively.

As described above, each terminal 22 is provided for each of a plurality of types of functional departments.
It may be distributed on multiple floors or factories. In the present embodiment, when an abnormality occurs in the manufacturing process, the warning information is immediately transmitted to the terminals arranged in a distributed manner. In the information on the abnormality, the production lot number and date and time of the product in which the abnormality has occurred, the processing device number, the type of the abnormality, and the like are linked in a predetermined data format.
In this embodiment, for example, these are used as warning information.

The details of the warning information are displayed on the display screen of the terminal. Specifically, for example, spreadsheet application software is used, or dedicated display application software is constructed and displayed. For example, when an abnormality occurs while the terminal uses another application such as word processing software, the display screen may be switched or warning information may be displayed on a part of the display screen. Further, a warning sound may be further emitted. Alternatively, instead of displaying the details of the warning information on the display screen as described above, the warning may be performed by blinking the display screen. Further, means such as an alarm lamp or an alarm buzzer may be separately provided in addition to the display terminal.

By the way, the types of abnormalities that occur in the manufacturing process are abnormally large, and there are several thousand types depending on the process. Under such circumstances, it is impractical to generate warning information and issue a warning to the user every time an abnormality occurs.
Further, in this embodiment, the terminal 22 is installed for each functional section, but information about an abnormality required by each functional section is generally different for each functional section. For example, the equipment maintenance management department mainly deals with equipment failure, the process technology management department deals with process failure, and the quality management department deals with both equipment failure and process failure.

Therefore, in this embodiment, the type of abnormality to be warned to the user can be customized and set in advance for each terminal. This setting content is stored in the storage device in the terminal 22 or the server 21. The warning unit 14 in the server 21 transmits the warning unit to the terminal when the detection unit 11 detects information about an abnormality set in advance for each terminal.

As described above, according to the manufacturing management system of the present invention, since information on manufacturing results and abnormalities in each manufacturing process is accumulated, various types of information can be searched for in the past history. Therefore, the manufacturing process can be efficiently grasped and managed. In addition, when an abnormality occurs in the manufacturing process, warning information is immediately transmitted to each terminal, so that even if an abnormality occurs in the product during the manufacturing process, workers and process managers can immediately respond,
For example, if a quick response is taken, such as stopping the process or changing the processing, the occurrence of defective products can be reduced.

Further, since each terminal is installed for each of a plurality of types of functional departments, it is possible for an expert to deal with the occurrence of abnormalities in a professional and prompt manner, Analysis processing becomes easy. Next, a modified example of the present invention will be described. FIG. 3 is a configuration diagram of a manufacturing management system according to a modification of the present invention.

The manufacturing management system 1 according to the present modified example is the same as the manufacturing management system shown in FIG. 1, but with an instructing means 15 for instructing at least one of the processes in the manufacturing process the processing content in the process. And a planner 16 for feeding back the information stored in the storage 12. Here, only the instruction unit 15 and the planning unit 16 will be described. The detecting means 11 and the storing means 1
2. Since the distribution means 13 and the warning means 14 have already been described, their description will be omitted.

The instruction means 15 and the planning means 16 are configured in the server 21 shown in FIG. In the example of FIG. 1, the recipe information for manufacturing the target product in the manufacturing process is stored in the computer attached to the processing device. However, the instruction means 15 in this modification stores the recipe information in the server 21. Desired recipe information can be transmitted to the control sequencer of each process by an operation from the terminal. Further, in addition to the recipe information, an instruction for starting or stopping the processing may be transmitted. Planning means 1
6 is to correct the in-process state of the product or the production plan based on the operation / stop / state information of the device stored in the storage unit 12;
Make changes or optimizations. Note that only one of the instruction unit 15 and the planning unit 16 may be provided.

According to the present modification, for example, the terminal in the quality control department is operated to retrieve the recipe information of an arbitrary process stored in the server 21 and transmit it to a predetermined device.
The manufacturing process can be remotely controlled. Further, for example, when the user receives the warning information, the user can transmit new recipe information again in response to the warning information. Further, the planning means 16 feeds back the operation information and the like accumulated by the accumulation means 12, and enables correction, change, and optimization of the production schedule (production line table).

As described above, according to the present modification, more detailed manufacturing control of the manufacturing process can be performed. The manufacturing management system according to the present invention described above is applicable to manufacturing processes of various products. For example, it is particularly effective in a plating process with a very large processing amount, which is one of the manufacturing processes of a printed board.

[0032]

As described above, according to the present invention,
Information on manufacturing results and abnormalities in each manufacturing process is accumulated. Therefore, the user can search various information at any time by going back to the past history, so that the quality of the manufacturing process and the product can be grasped and managed more efficiently. In addition, since numerical data for a completed product can be acquired, it is possible to provide, for example, objective quality assurance to a delivery destination of the product.

Further, when an abnormality occurs in the manufacturing process, the warning information is immediately transmitted to each terminal. Therefore, even if an abnormality occurs in the product during the manufacturing process, the worker and the process manager can grasp the situation in real time. For example, it is possible to quickly respond to a stop of a process or a change in a process, and it is possible to reduce the occurrence of defective products. Furthermore, since each terminal is installed for each of a plurality of functional departments, it is possible for specialists to respond quickly and professionally to the occurrence of abnormalities, and to perform specialized analysis processing on the obtained history information. Also becomes easier.

The control sequencer in each terminal and each manufacturing process is connected to the server via a line. Therefore, if a LAN connected to this server is configured, the history, operation status, and occurrence of abnormality of each manufacturing process can be easily grasped or searched by simply connecting the terminal to the LAN. In the above description, the terminal is a normal stationary computer, but other than this, for example, a PDA (Per
An information portable terminal such as a personal digital assistant or a mobile phone may be used. In this case, for example, information relating to the production results may be sent as an attached file to an e-mail, or a call may be made to a mobile phone when an abnormality occurs. As a result, it is possible to acquire information on manufacturing results and abnormalities without depending on locations.

Further, using a notebook personal computer having a communication function as a terminal and a portable telephone or a public telephone,
You may connect to a server via a public line network. in this case,
For example, the user can grasp the operation status of the manufacturing process, the occurrence of an abnormality or the history thereof even in the city or at home.
