The factory name is identification information for identifying the factory, and the information acquisition request is a print rate information table, a facility operation condition information table, an image recognition information table, and a reflow success rate information table stored in the information storage unit 332. Requests transmission of information in any of the tables. When the factory name and the information acquisition request are received (step S233), the equipment and the central management device 151 mutually perform device authentication processing via the transmission / reception unit 335 (step S234).

If the mutual device authentication process is not successful (NG in step S234), the control unit 331 sends a message to the facility via the transmission / reception unit 335 to reject the information acquisition request. (Step S23)
8) Then, the process returns to step S231 to repeat the processing. If the mutual device authentication process is successful (step S
234, OK), the control unit 331
In step S235, a paid category associated with the received factory name is searched for from the access rank table stored in the storage rank table.

If the paid category is "paid" (step S236), the control unit 331 determines whether or not the charging process has been completed, and if not completed (step S2).
36), the control is shifted to step S238. Here, the billing process is well-known, and thus the description is omitted. If the paid category is “free” (step S236),
Alternatively, if the paid category is "paid" (step S236) and the charging process is completed (step S23).
7), the control unit 331 searches the access rank table stored in the information storage component 332 for an access rank associated with the received factory name, and acquires an access rank (step S239).

Next, the control unit 331 extracts all information including the same disclosure level as the acquired access rank from the table to which the information acquisition request is applied (Step S).
240), the extracted information is collectively transmitted as a table to the facility via the transmission / reception unit 335 (step S241). Next, the process returns to step S101 to repeat the processing.

(Mutual Device Authentication Processing Between Each Facility and Central Management Apparatus 151) Facilities such as factory facilities and the central management apparatus 1
The mutual device authentication process with the device 51 will be described with reference to the flowchart shown in FIG. The device authentication process is a challenge-response type authentication. Here, a process in which the central management device 151 authenticates “whether or not the facility is a legitimate device” will be described.
The process for authenticating whether or not the central management device 151 is a legitimate device by the facility is the same.
Description is omitted.

In the following, a description will be given assuming that the processing is device authentication processing between the central management apparatus 151 and the factory management apparatus 104. The control unit 331 generates a random number R (Step S251), and transmits the generated random number R to the control unit 321 via the transmission / reception unit 335, the intranet 21, the transmission / reception unit 325, and the like (Step S252).

The control unit 331 performs an encryption algorithm E on the generated random number R using the encryption key K as a key.
An authentication code M is generated (step S253). On the other hand, the control unit 321 receives the random number R,
The cryptographic algorithm E is performed using the cryptographic key K as a key to generate an authenticator M ′ (step S254), and the generated authenticator M ′ is transmitted to the transmitting / receiving unit 325 and the intranet 21.
Then, the control unit 331 transmits the authenticator M ′ via the transmission / reception unit 335 and the like (step S255).

The control unit 331 determines whether or not the authenticator M and the authenticator M ′ match.
256), the factory management device 104 is authenticated as a legitimate device (step S257). If they do not match (step S256), it is authenticated that the factory management device 104 is not a valid device (step S258).

Here, the encryption algorithm E is DES
(Data Encryption Standard)
It shall be based on. Note that another encryption algorithm may be used. 1.13 Operation of factory equipment Factory equipment 10, 11, 12, factory equipment 31, 32, 33
The operation when information is acquired from various tables stored in the central management device 151 will be described.

(1) Operation of factory management device Factory equipment 10, 11, 12, factory equipment 31, 32, 33
The central management device 15
The operation of the process of acquiring information from the various tables stored in 1 will be described with reference to the flowchart shown in FIG. The factory management device further operates as described below.

The factory management device sends a factory name for identifying the factory and an information acquisition request to the central management device 151 (step S261). Here, the information acquisition request is:
Requests transmission of information in any one of the printing rate information table, the equipment operation condition information table, the image recognition information table, and the reflow success rate information table stored in the information storage unit 332 of the central management device 151. Things.

Next, the factory management device is connected to the central management device 15.
1 (step S262), and transmits the received information table to the corresponding production device via the production line management device (step S2).
63). (2) Operation of Production Apparatus The operation of the production apparatus when each information table is obtained from the factory management apparatus will be described with reference to the flowchart shown in FIG.

Here, the production apparatus refers to any one of a cream solder printing machine, a high-speed placement machine, a multi-function placement machine, and a reflow device. Each production device further operates as described below. The control unit of the production device acquires an information table from the central management device 151 via the production line management device (step S271), and stores the acquired information table therein (step S272). Next, the control unit of the production device deletes information that does not match the production device. Specifically, if the production device is a cream solder printing machine, the control unit extracts the printing rate information table and deletes other information. If the production equipment is a high-speed mounting machine,
The control unit extracts the equipment operation condition information table and deletes other information. If the production equipment is a mounting part inspection machine,
Extract the image recognition information table and delete other information.
If the production device is a reflow device, the reflow success rate information table is extracted and other information is deleted (step S273). Next, the control unit of the production device converts the information included in the information table into a rate (where the rate is a recognition rate,
The information is rearranged in descending order of mounting rate, printing rate, and reflow success rate, and a new information table is created (step S27)
4).

Next, the control unit of the production apparatus sequentially reads out one piece of information from the information table (step S275),
When the reading is completed (Step S276), the production apparatus starts the production processing (that is, the processing of processing the circuit board) (Step S281). If the reading is not completed (step S276), the control unit of the production device
The read information is the production process (processing) of each circuit board
It is determined whether or not the information matches the condition under which is to be performed, or is similar information.

If the information matches or approximates (step S277), the control unit of the production apparatus sets the read information inside as a condition (step S2).
78). Next, the production equipment, according to the set conditions,
A production process (that is, a processing process of the circuit board) is performed (step S279). Next, actual values are measured and totaled, and a rate (where the rate is the recognition rate, the mounting rate, the printing rate, the reflow success) Is calculated (step S280).

The control unit of the production apparatus compares the results obtained by changing the conditions in this way with the results before the conditions are changed, determines whether or not the results are reduced, and changes the conditions. If the obtained results have not decreased (step S28)
1) Return to step S279 and repeat the process. If the result obtained by changing the conditions is lower (step S281), the process returns to step S275 to repeat the processing.

In step S277, the condition is met, for example, when the squeegee speed, squeegee pressing force, squeegee angle, solder material, substrate type, stage descending speed, cleaning condition, It shows that all items are the same for the production line number, the printing device type name, and the printing device number.

Also, approximation indicates that some of these items match. For example, in the printing rate information table, squeegee speed, squeegee pressing force, squeegee angle, solder material, board type, stage descent speed, cleaning condition, production line number, which constitute printing conditions,
In this case, all items except the solder material are the same for the printing device type name and the printing device number, and only the solder material is different. Although only one item is different, more items may be different.

1.14 Operation of Factory Equipment 41 The operation of the factory equipment 41 when acquiring information from various tables stored in the central management unit 151 will be described with reference to the flowchart shown in FIG. Here, the factory equipment 41 is not connected to the central management device 151 via the Internet 22 or the intranet 21.

The mobile phone 25 receives an information acquisition request input from a user (step S301). Here, the information acquisition request is sent to the information storage unit 3 of the central management device 151.
The transmission of information in any one of the printing rate information table, the equipment operation condition information table, the image recognition information table, and the reflow success rate information table stored in the table 32 is requested.

Next, the mobile phone 25 transmits the information acquisition request to the central management device 151 via the wireless base station 24 and the mobile phone network 23, and the central management device 151 receives the information acquisition request. (Step S302). Next, the mobile phone 25 and the central management device 151 mutually perform authentication processing (steps S303 and S304). If the authentication fails (step S305), the processing ends.

When the authentication is successful (step S30)
5), the central management device 151, in accordance with the information acquisition request,
The corresponding information is acquired (step S306), and the acquired information is transmitted via the mobile phone network 23 and the wireless base station 24.
The information is transmitted to the mobile phone 25, and the mobile phone 25 acquires the information (step S307). The mobile phone 25 writes the acquired information into a portable semiconductor memory card provided therein (step S308).

Each production device includes a reading component for reading information stored in the semiconductor memory card. The user extracts the portable semiconductor memory card from the mobile phone 25 and mounts the extracted semiconductor memory card on a production device. The production device acquires information from the inserted semiconductor memory card (step S309).

Next, the production device starts the operation from step S272 in the flowchart of FIG. 2. Other Embodiments As described above, the present invention manages the component library of each factory, NC data in a database in the central management unit, and implements a component library for mounting a new model board, an NC.
Provide data. The data provided here is data having a proven track record. In the production apparatus provided with the information, the man-hour for data creation can be reduced, and the time for switching to mounting on a new model board can be reduced.

Although the present invention has been described based on the above embodiment, it is needless to say that the present invention is not limited to the above embodiment. That is, the following cases are also included in the present invention. (1) In the above embodiment, a plurality of different types of production apparatuses are connected to each other in the production line facility.
The production line equipment may consist of one production device.

The factory is a CAM (Computer)
An Aided Manufacturing (CAM) system is provided, and the CAM system includes a library in which information on circuit boards and components is stored. The production line equipment may be connected to a CAM system via an internal network, and the production line equipment may acquire information on circuit boards and components from the CAM system.

For example, in the case of factory A, when mounting on a new board is desired, if there is no information on components to be mounted on the board in factory A, the factory equipment of factory B is accessed and Necessary information may be acquired from factory equipment of the factory. As described above, the information may be referred to each other between the factories. This is repeated by the number of components necessary for the new board, and data can be acquired to start mounting the new board. As a result, the time to input data on new parts is reduced,
Input errors can be reduced, and production can be started immediately.

Further, a server having a data search function may be provided in the factory. Thus, by referring to each other's data between factories and by using a server with a data search function, the factory can efficiently search for the data that the factory wants. Become like Further, the factory equipment may be connected to a server including a design support tool.

(2) The factory equipment of each factory may include a server having a data library storing information on parts and the like, and the server may be connected to the Internet, an intranet, or an extranet. Other factory servers may be able to access the data library of the server. The software (computer program) stored in the server may have a search function, acquire data from a data library existing in another factory, and add the received data to its own data library.

This function is realized when the server has two functions, a search function and a search function.
The search function checks whether the data held by another server matches the search target data. A plurality of search targets such as name, date, and result data can be set, and these can be arbitrarily combined. For example, factory A sets only the name of the component shape data, and searches factory B for whether the data of the component name exists.

The result obtained by searching the data library of the factory B is sent back to the factory A via the network together with the name information of the data found in addition to the name found by the search. Even if a search result is found by a search specifying a plurality of conditions, all of those data
Send back to factory. Factory A determines whether to acquire data from Factory B when Factory B owns the data, and if so, performs acquisition processing from the operation screen of the server and acquires data from Factory B I do. The obtained data is added to the library data of Factory A. If the data already acquired by Factory A is the data already owned by Factory A, the library data is updated.

Here, it is assumed that a part to be newly created is A. A
The search device in the factory receives, for example, the input of the name of the part A as the search condition. In addition, the search device accepts an input of a server destination address and transmits search conditions to a server specified by the address. Next, the server specified by the address receives the search condition, the server performs a search in accordance with the search condition, and returns a search result to Factory A as a response. Factory A receives the search result, and if the search result is necessary information, adds it to the server of Factory A as new component data.

(3) There may be one global server in the production information system for centrally managing the component library of the equipment, and each factory and the global server may be connected via a network. Note that a plurality of global servers may exist. Next, a case where the factory A acquires data will be described.

The factory A searches the global server to check whether necessary component data is registered. If the necessary component data exists in the global server, the global data returns a search result to Factory A as a response. Thereafter, if the searched data is necessary, Factory A downloads the data from the global server and obtains the target data.

In operating the global server, data created in each factory is registered in the global server, and the data in the global server is updated manually or automatically. In the case of a manual update, the data of the global data is additionally updated by performing data registration work on the global server in the factory server and transferring the data to the global data. In the case of automatic updating, the factory server accesses the global server periodically, and performs an operation of uploading data when there is no data in the global data.

(4) The case where factory A obtains data from an existing factory will be described. Each server of each factory is a client capable of exchanging data, and is configured by a network having a server function. Factories exchange data between factories. When factory A searches for necessary data, it first inquires whether there is data at factory B connected to factory A. At this time, if data exists in factory B, factory B
Reply to the factory. Factory A downloads data from Factory B when it wants to acquire data from Factory B.

If the necessary data cannot be found at the factory B, the factory B sends the data to the factory C connected to the factory B.
Query the same search content. At this time, factory A
It does not sense that the factory was contacted by factory C.
Here, if the data does not exist in the factory C, the factory C inquires the factory D about the data search. When the search is completed at all the connection destinations, the process ends.

With this configuration, it is not necessary to construct a server, and in many cases, there is no need for a cost for centralized management. Data can be obtained even when the server is down. However, it takes more time to acquire all the data compared to the method of centrally managing the server. (5) A case where factory A acquires data from factory B will be described.

First, one central server having a database for managing what data each factory has other than the factory is prepared. Note that at least one central server is required, but a plurality of central servers may exist. The database of the central server stores what data the servers of the connected factories have.
This data is updated by periodically uploading data that the server of each factory has when accessing this server. However, the database of the central server only holds the names of the data held by the factories and the addresses to the factories, but does not hold the actual data. The data itself is held by the server at each factory.

As the address data, for example, if TCP / IP is used as the communication protocol, the IP address is stored in the database. In other network connection methods, if the information can specify the location of the server, the location of the server is identified by recording the information. Factory A searches data of other factories,
To get it, first access the central server.
The factory A searches the database of the central server as to which factory owns the data searched. By the search in the central server, the name of the owned factory and the data name found in the search are returned to the factory A. A
The factory receives the response from the central server, and if there is data to be acquired from the response, the factory replies as to which factory has the data. At this time, if a server having data is found, the server directly accesses the server and receives the data.

The registration of data from each factory to the central server is performed periodically while the system is being started.
This interval is to update data three times a day in consideration of the load on the central server and the degree of data update.
Of course, depending on the system, if the data needs to be updated frequently, the setting can be made six or ten times a day.

In this system, the maintenance of the server is more difficult than in the system in which data is conventionally stored in the server, but actual data can be obtained and data can be searched at high speed. It is characterized by the following. Also, since the server has only a pointer indicating which factory has data and does not have actual data, the server does not need to have a large capacity, and maintenance is easy.

(6) The component data has data indicating the shape of the component. This indicates the size of the component, and is represented by its shape, length, width, and height. Further, information indicating how the component is packaged, for example, whether it is a tape, a tray, or a bulk, may be held. (7) The equipment may have operating parameter data such as the speed and height at the time of mounting and the size of the nozzle as conditions for operating the equipment.

(8) The mounting quality of each component produced in the facility is recorded, the data is uploaded to a server, and managed as performance data. Specifically, the mounting quality records a component mounting error. By transferring this performance data together with other component data, the reliability and quality of the data can be known, and the decision is made to the side using the data. Also, by comparing the performance data of other factories with the performance of your own factory,
The quality of the factory can be improved.

(9) Since visual recognition may be used in mounting components, the mounting machine holds the data of the visual recognition. This data is also registered with the component name similarly to the component data, and can be searched by the component name. (10) Regarding the above (6) to (8), part of the data,
Or you can use all as search criteria,
The highest quality can be achieved by selecting the data with the highest quality when there is a plurality of component data.

(11) Each server can set a server to which data is not to be passed or a partner to whom data can be passed. In addition, it is possible to set whether it is data that can be disclosed to the data itself or data that you do not want to have public relations. A partner may be selected by a network address.

(12) Rank information is attached to data to be made public, and this data is used as a reference for the other party. For example, Rank 1: Data from the field operation, Rank 2: Tested data, Rank 3:
And verification data. With this method, the searching side can know the degree of data verification, and can judge whether the received data can be immediately tested or not.

(13) In the above search (3) to (5), if there is no data as a result of the search, a component library of a component maker is registered in advance in the server on the search side, and the component is stored in the search data. A manufacturer may be selected, accessed, and component data may be acquired. As a result, the time for acquiring component data and creating new data can be reduced.

(14) In the above search (3) to (5), if there is no data as a result of the search, a data result of a similar type is returned. In the case of a parts library, lists data with similar numerical values from the data of the size, shape, characteristics, and manufacturer, and returns data that can be replaced and that is similar to those data even if the searched data does not exist. This makes it possible to reduce data entry labor.

(15) Although data has already been acquired, a part different from data of other factories may be found and used as a guide for equipment tuning. By comparison, it is also possible to replace the data with data that can provide even better quality. (16) Create a list of data differences and implementation quality,
It may be used as a guide for creating good-quality data.

(17) For example, a case where factory A obtains data from factory B will be described. The server of the factory A has logging means for recording when and what data is distributed from which factory. Here, it is assumed that the factory A downloads data in the factory B.

When the data is sent from the factory B to the factory A, the server of the factory B records a distribution log indicating that the data has been transmitted to the factory A. Further, the server of the factory A records a reception log indicating that data has been received from the factory B. If there is more than one data, distribution log at any time,
Record the reception log. In this way, the factory B can know the distribution record to the factory A by looking at the distribution log. Using this distribution record, factory B may charge factory A when it needs a data distribution fee to factory A. The factory B can set data that is not charged depending on the data, and is recorded in the distribution log of the factory B even when it is free.

(18) To perform a search, a WWW browser may be used. Here, a case where a search is performed from factory A to factory B is considered. WWW browser is A
When searching for data stored in the local database in the factory or when searching for data stored in the database of factory B, an automatic search is performed and the browser is operated as if it were in the local database. On the same screen. Thus, the same operation can be performed without being aware of the local and remote databases.

(19) Here, a case where a search is performed from the factory A to the factory B will be described. Factory A downloads and records the parts registration list in the system of Factory B in advance. The part registration list contains the name of the part,
Includes part numbers and does not include information on substantial parts. A
The factory searches this parts registration list, and if there is necessary data in the parts registration list, requests the factory B to transmit data. Upon receiving this, the factory B extracts the target data from the internal database and transmits the extracted data to the factory A. Factory A receives the extracted data. In this way, the amount of inquiry communication can be reduced, and data search can be performed quickly. Further, information on a plurality of parts may be received at the same time.

(20) The data retrieval from the client server of the factory has means for setting various retrieval units such as only components, components not on the board, and components not in the system. It may be selectable. For example, all data that does not currently exist in the server can be checked against servers in other factories. (21) The global server may enable registration from a component manufacturer in the component library. By this registration, the trouble of searching for component data is reduced, and the trouble of inputting is also reduced.

(22) The global server may collectively register the data with a proven track record in the server. Whether there is a track record or not, the board is actually mounted, and data exceeding the non-defective rate exceeding a certain rule is registered in the server. By sharing high-quality data in the network, it is possible to expect an improvement in the non-defective rate in all facilities. (23) By using the quality verification data collected in the server, a board mounting simulation is performed using the data of the equipment configuration and the board to be mounted, and the tact of mounting and the rate of non-defective products are analyzed. Is also good.

(24) The quality verification data and the parts library necessary for the simulation may be collected via a network. (25) The central management device 151 may further store various types of information. For example, information on technicians for dispatching technicians to each factory, information on product specifications and inventory, diagnostic information for diagnosing the production status of factories, charging information for charging each factory, etc. is there.

The mobile phone 25 displays a search screen for searching for such information. The user specifies such information from the search screen. The mobile phone 25 generates an acquisition request for acquiring the specified information, and
The data is transmitted to the central management device 14 via the wireless base station 24 and the mobile phone network 23. The central management device 151 receives the acquisition request, extracts necessary information from the inside based on the received acquisition request, and outputs the extracted information to the mobile phone network 2.
3. Transmit to the mobile phone 25 via the wireless base station 24.

Mobile phone 25 receives the information and displays the received information on the display unit. Alternatively, the received information is written in a portable semiconductor memory card attached to the mobile phone 25. In this manner, various types of information can be obtained from the mobile phone, so that various types of information can be provided to each factory. (26) In the above embodiment, the central management unit 15
In the case where information is acquired from No. 1, a fee is charged for the factory from which the information is acquired. However, there are various conditions for charging, and the following may be performed.

When a factory to be charged acquires information from the central management unit 151, a fixed amount may be charged each time information is acquired. Alternatively, of the information to be obtained, only valid information may be charged. Here, an example of the effective information is only information in which the rate (reflow success rate or the like) included in each of the tables is 99% or more.

[0193] The central management unit 151 sets the
The number of references indicating the number of references from each factory is counted and stored, and the amount of charge may be changed for information corresponding to the number of references larger than a predetermined value. For example, the charge amount may be increased. (27) The central management device is a production rate that indicates in advance the production conditions actually used when performing the processing in another production apparatus and the yield of the product produced by performing the processing using the production conditions. A plurality of production information consisting of is stored, the production information including the highest production rate is selected from the stored plurality of production information, and in response to a request from a production device, the selected production information is read out. The read production information may be transmitted to the production device. In this case, the production device may receive the production information selected from the central management device, and process the semi-finished product using the production conditions included in the received production information.

(28) In the above embodiment, application to the electronic component mounting system has been described.
The application is not limited to the electronic component mounting system. It can be applied to other production systems. For example, similarly to the above-described electronic component mounting system, the present invention can be applied to an automobile production system. (29) The present invention may be the method described above. Further, these methods may be a computer program that is realized by a computer, or may be a digital signal formed by the computer program.

The present invention also relates to a computer-readable recording medium for the computer program or the digital signal, for example, a floppy (registered trademark) disk, a hard disk, a CD-ROM, an MO, a DVD, a D
The information may be recorded on a VD-ROM, a DVD-RAM, a semiconductor memory, or the like. Further, the present invention may be the computer program or the digital signal recorded on these recording media.

In the present invention, the computer program or the digital signal may be transmitted via an electric communication line, a wireless or wired communication line, a network represented by the Internet, or the like. The present invention may also be a computer system including a microprocessor and a memory, wherein the memory stores the computer program, and the microprocessor operates according to the computer program.

Further, by recording the program or the digital signal on the recording medium and transferring it, or by transferring the program or the digital signal via the network or the like, another independent computer system is provided.

[0198]

As described above, the present invention is directed to a production apparatus for producing a product by processing a semi-finished product under predetermined production conditions, wherein the production is performed in another production apparatus. Receiving means for receiving, from an external device, a plurality of pieces of production information including a production condition actually used and a production rate indicating a yield of a product produced by performing processing using the production condition, A selection means for selecting production information including the highest production rate from a plurality of pieces of production information, and a production means for processing a semi-finished product using the production conditions included in the selected production information.

According to this configuration, when starting production of a new product, production can be started early. Here, the selecting unit extracts production information including production conditions used in another production device of the same type as the production device from among the received plurality of production information, and selects the highest production information among the extracted production information. You may comprise so that the production information containing a production rate may be selected.

According to this configuration, production can be performed using production information with a high yield and a proven track record. Here, the production apparatus further includes a production condition storage unit that stores another production condition before receiving the production information, and the selection unit includes a plurality of pieces of received production information. The production information may be selected from those including production conditions that are similar to the other production conditions.
