In such production line 1, apparatus for inspecting solder printing 102a, parts installation check device 102b, base board checking device 102c, terminal 104, process management device 103, LAN constitute above-mentioned Working procedure management system.
Then the FBD (function block diagram) with reference to Fig. 1 describes this Working procedure management system.
As shown in Figure 1, Working procedure management system 100 has a plurality of testing fixtures 102, process management device 103, reaches terminal 104.Though and not shown, each testing fixture 102, process management device 103, terminal 104 have the I/F that communicates by letter (interface) that carries out signal transmitting and receiving by LAN and other devices respectively.
And each testing fixture 102a, the 102b among Fig. 2,102c are corresponding with each testing fixture 102 among Fig. 1 respectively.
Below process management device 103 and terminal 104 are elaborated.As shown in Figure 1, process management device 103 has control part 110 and storage part 120, and terminal 104 has display part 105 and input part 106.
Then to each piece of control part 110, and storage part 120 in the data of storage be elaborated.
And the various data of storage part 120 storages comprise: working procedure states DB (database) 121, unusual/reason corresponding tables (first sets up corresponding informance, second sets up corresponding informance) 122, unusual/reason DB123.
And each parts that contains in the control part 110 are to carry out program stored in the storage part 120, control the functional block that not shown peripheral circuit such as imput output circuit are realized by CPU (Central ProcessingUnit, central arithmetic processing apparatus).
Working procedure states collection unit 111 is used for being collected in the status information of each product that each equipment (each operation) of above-mentioned production line handles, particularly, be used for being collected in the production code member data and the qualitative data of the processed product of each equipment from all testing fixtures 102.The production code member data of the product that working procedure states collection unit 111 will receive from testing fixture 102 and the qualitative data of this product are set up corresponding, with the working procedure states DB121 that records storage part 120 its time of reception simultaneously.
Operation abnormity detection portion 112 is: for all products of certain batch of product, when working procedure states collection unit 111 is finished production code member data and qualitative data behind the record of working procedure states DB121, with reference to the data that write down among the working procedure states DB121, it is unusual that each product is detected all that take place in each product successively, and detect each unusual kind.
Particularly, operation abnormity detection portion 112 is carried out each product according to management method and whether unusual judgement is taken place, reach the appointment to each the unusual unusual kind that takes place according to qualitative data of storing among the working procedure states DB121 and production code member data.In addition, this judgement and appointment also can be carried out according to the judgment rule of JIS (Japanese Industrial Standard) regulation, also can be stipulated voluntarily by the user.
And unusual product has taken place for judgement in operation abnormity detection portion 112, make this product the production code member data, and the combination of the abnormal information of the unusual kind that takes place of this product of expression set up correspondingly, send to cause information collection unit 113.Wherein, the combination of abnormal information is meant and at least one abnormal information that product is corresponding.That is, a product is sent a plurality of abnormal informations sometimes.This is because a product has taken place multiple unusual.
For example, be in the product of " 0003 " in the production code member data, suppose the unusual of " scolding tin is very few " takes place in the solder printing operation of solder printing device 10, the unusual of " parts float " takes place in the reflow process of reflux 30.In this case, in the data that operation abnormity detection portion 112 writes down in working procedure states DB121, in each qualitative data corresponding with production code member data " 0003 ", according to the qualitative data that receives from apparatus for inspecting solder printing 102a, detecting unusual and detecting this unusual kind is " scolding tin is very few ".Simultaneously, operation abnormity detection portion 112 is in the information of working procedure states DB121 record, in each product data corresponding with production code member data " 0003 ", according to the qualitative data that receives from base board checking device 102c, detecting unusual and detecting this unusual kind is " parts float ".And operation abnormity detection portion 112 is set up production code member data " 0003 " and abnormal information " scolding tin is very few " and abnormal information " parts float " corresponding, and sends to cause information collection unit 113.
When cause information collection unit 113 receives each abnormal information and production code member data from operation abnormity detection portion 112 according to each product, with reference to unusual/reason corresponding tables 122, according to each product, the corresponding abnormal cause information of the combination of each abnormal information of reading and receiving.
Wherein, unusual/reason corresponding tables 122 be the combination that will be illustrated in the abnormal information of the unusual kind that takes place in the above-mentioned production line, the abnormal cause information (improvement utilizes information) of representing the reason that this is unusual, and the process information of determining to take place the operation of this abnormal cause set up corresponding table.
Further, cause information collection unit 113 according to each product will from unusually/abnormal cause information that reason corresponding tables 122 is read, unusually/set up corresponding process information with this abnormal cause information the reason corresponding tables 122, reach the production code member data recording to unusually/reason DB123 in.
This to unusually/reason corresponding tables 122 and unusual/reason DB123 be elaborated.
At first, to unusually/reason corresponding tables 122 describes.Fig. 3 is the exemplary plot of the memory contents of unusual/reason corresponding tables 122.In the unusual/reason corresponding tables 122 of this example, " scolding tin is too much " " scolding tin is very few " " dislocation " of putting down in writing in each file ... be respectively the abnormal information that is illustrated in the unusual kind that takes place in the operation, " mask contamination " of record " it is slow that scolding tin is changed " " mask is fixing bad " is respectively the abnormal cause information of this unusual reason of expression in respectively walking crosswise.
And the corresponding relation of the combination of abnormal information and abnormal cause information is as by above-mentioned each file with respectively walk crosswise shown in the circular mark of each frame that constitutes.
For example, if during the combination of abnormal information of being conceived to " scolding tin is very few " and abnormal information " parts float ", should " scolding tin is very few " reach in the affiliated frame of " parts float " two files, putting down in writing walking crosswise of circular mark only is to belong to walking crosswise of " mask contamination " " it is slow that scolding tin is changed ".That is, the such abnormal cause information foundation of this combination of abnormal information " scolding tin is very few " and abnormal information " parts float " and " mask contamination " " scolding tin change slow " is corresponding.
Therefore, when cause information collection unit 113 receives abnormal information " scolding tin is very few " and this combination of abnormal information " parts float " to certain product (, what this product took place unusually only is " scolding tin is very few " " parts float ", other do not take place when unusual), with reference to unusual/reason corresponding tables 122, retrieve in the frame that belongs to two files of abnormal information " scolding tin is very few " " parts float " and put down in writing walking crosswise of circular mark.And, belong in the frame of two files of abnormal information " scolding tin is very few " " parts float " and put down in writing walking crosswise of circular mark, only be to belong to walking crosswise of abnormal cause information " mask contamination " " it is slow that scolding tin is changed ".Therefore, cause information collection unit 113 receives the combination of abnormal information " scolding tin is very few " " parts float " to certain product, and when not receiving other abnormal informations, reads abnormal cause information " mask contamination " " it is slow that scolding tin is changed ".
It should be noted at this, shown in Figure 3 unusual/reason corresponding tables 122 finally is the table of the corresponding relation of the combination of expression abnormal information and abnormal cause information.This point is carried out following detailed description.
In production line, kind is mutually different, and each is unusual, combine with mutually different each the abnormal cause intricately of kind.Particularly, of producing for certain product is unusual, and inferring sometimes has a plurality of abnormal causes, and an abnormal cause can cause a plurality of unusual (kind is mutually different a plurality of unusual) to certain product sometimes.
Therefore, during to detected its abnormal cause of unusual supposition in certain product,, but consider the relation unusual with other even this is listed a plurality of abnormal causes unusually as the candidate, can be further combined with the candidate of abnormal cause.Particularly,, there are a plurality of abnormal causes to enumerate out, but, can from this candidate, get rid of for abnormal cause as nd unusual reason in this product as candidate for detected unusual in certain product.
For example in Fig. 3, if during the abnormal information of being conceived to " parts float ", in each frame that belongs to the file of having put down in writing abnormal information " parts float ", the frame of having remembered circular mark is to belong to the frame of walking crosswise of having put down in writing abnormal cause information " mask contamination ", " it is slow that scolding tin is changed ", " mask is fixing bad ", " gas anomaly ".Thus, as the reason of unusual " parts float ", the candidate comprises " mask contamination ", " it is slow that scolding tin is changed ", " mask is fixing bad ", " gas anomaly ".
But, when detected to certain parts unusually only be " parts float ", and other do not take place when unusual, reason that should unusual " parts float " can be attached to " gas anomaly ".This be because, if above-mentioned unusual " parts float " is not only and produced because of abnormal cause " gas anomaly ", also be because other abnormal causes " mask contamination " " it is slow that scolding tin is changed " " mask is fixing bad ", not only should detect " parts float ", also should detect unusual (with reference to Fig. 3) of " scolding tin is very few " " dislocation ".
Therefore, when to the unusual abnormal cause of inferring separately of detected each of product, be not with separately the unusual abnormal cause of inferring all as the candidate, for a product, will get final product as the candidate according to the abnormal cause that detected all unusual combinations are inferred.Based on this reason, unusually/reason corresponding tables 122 in, the combination of abnormal information and abnormal cause information are set up corresponding.
For example, when cause information collection unit 113 only receives the combination of " parts float " this abnormal information to certain product (, this product unusually only be " parts float ", other do not take place when unusual), with reference to unusual/reason corresponding tables 122, only retrieval belongs in the frame of file of abnormal information " parts float " and has put down in writing walking crosswise of circular mark.At this, belong in the frame of file of " parts float " and put down in writing walking crosswise of circular mark, only be the row of " gas anomaly ".Therefore, cause information collection unit 113 only receives the abnormal information of " parts float " to certain product, and when not receiving other abnormal informations, only reads abnormal cause information " gas anomaly ".
And, unusually/reason corresponding tables 122 in, make each unusual cause information, set up connection and storage with the process information of the operation that each abnormal cause specify to take place.In Fig. 3, for example make the abnormal cause information of " mask contamination " " it is slow that scolding tin is changed " " mask is fixing bad " set up connection, make the unusual connection information of " box is crooked " " spray nozzle clogging " " gas anomaly " and " parts installation procedure " set up connection with the process information of " solder printing operation ".
This unusual/reason corresponding tables 122 in, cause information collection unit 113 receives production code member data according to each product and the combination of the unusual abnormal information representing to take place in this product, reads with the combination of this abnormal information and sets up corresponding abnormal cause information, and and the corresponding process information of this abnormal cause information foundation.
Then to unusually/reason DB123 describes.As mentioned above, cause information collection unit 113 according to each product will from unusually/abnormal cause information that reason corresponding tables 1232 is read, set up corresponding process information with this abnormal cause information, reach the production code member data recording to unusually/reason DB123.
Therefore, unusually/reason DB123 in, record according to each product: the production code member data, be illustrated in the unusual reason that takes place in this product abnormal cause information, set up corresponding process information (that is, being used to have determined to take place the information of the operation of unusual reason) with this abnormal cause information.
This to unusually/the content illustrated example of the data that write down among the reason DB123.Fig. 4 be to unusually/recorded content among the reason DB123 carries out the synoptic diagram of example.
In Fig. 4, for example in belonging to respectively the walking crosswise of production code member " 0003 ", write down abnormal cause information " mask contamination " " it is slow that scolding tin is changed ", in the walking crosswise under this abnormal cause information " mask contamination ", write down process information " solder printing operation ", also write down process information " solder printing operation " in the walking crosswise under this abnormal cause information " scolding tin change slow ".
This means, to production code member " 0003 ", abnormal cause information " mask contamination " " it is slow that scolding tin is changed " is set up corresponding and is recorded, process information " solder printing operation " is set up corresponding with this abnormal cause information " mask contamination " and is recorded, further, process information " solder printing operation " is set up corresponding with this abnormal cause information " it is slow that scolding tin is changed " and is recorded.
And shown in the example of Fig. 4, recording exceptional cause information not only among unusual/reason DB123, and can write down with the abnormal cause information that is write down and have the abnormal information of corresponding relation.
In the example of unusual/reason DB123 of this Fig. 4, for each product, when record from unusually/during abnormal cause information that reason corresponding tables 122 is read, directly set up corresponding walking crosswise with this abnormal cause information in recording exceptional/reason corresponding tables 122 (with reference to Fig. 3).
Particularly, as shown in Figure 4, for production code member " 0003 ", write down the abnormal cause information of " mask contamination " " it is slow that scolding tin is changed ", when being conceived to walking crosswise under this " mask contamination ", in the frame that belongs to the file of having put down in writing " scolding tin is very few " " parts float " with circular mark.This means that for production code member " 0003 ", abnormal information " scolding tin is very few " and abnormal information " parts float " are set up corresponding with abnormal cause information " mask contamination " and be recorded.Thus, the abnormal cause information for to each product record can clearly write down the combination as the abnormal information of the basis of reading and write down this abnormal cause information, the concrete analysis after helping.
And, shown in Figure 4 unusual/reason DB123 only is an example, need not the same recording exceptional information with this figure.
Then frequency data preparing department 114 is described.After frequency data preparing department 114 finishes the processing of operation abnormity detection portion 112 and cause information collection unit 113 at all products to certain batch of product, with reference to all abnormal cause information that write down among unusual/reason DB123, according to each kind of abnormal cause information, calculate abnormal cause recording of information number.
Wherein, above-mentioned record number is equivalent to the read frequency of each kind of the abnormal cause information of cause information collection unit 113.
Therefore frequency data preparing department 114 respectively writes down the read frequency of number as each kind of the abnormal cause information of cause information collection unit 113 with each kind of abnormal cause information, making gathers the frequency data of this read frequency, sends to chart production portion 115.
Then the example of the frequency data made by frequency data preparing department 114 is represented in Fig. 5.According to frequency data shown in Figure 5, in abnormal cause information, the read frequency of " it is slow that scolding tin is changed " is 4, and the read frequency of " mask contamination " is 2, and the read frequency of " temperature rises not enough " is 2.
Then the process flow diagram of the treatment scheme in the process management device 103 of above-mentioned structure with reference to Fig. 9 described.
As shown in Figure 9, at first, it is corresponding that working procedure states collection unit 111 is set up the qualitative data of the production code member data of the product that receives from each testing fixture 102... and this product, with (step 11 (below be called " S11 ") among the working procedure states DB121 that records storage part 120 this time of reception simultaneously.Other steps are represented too).
At this, control part 110 judges whether finish (S12) to what all product sequence state collection units 111 of certain batch of product were carried out to working procedure states DB121 record the said goods numbering data and qualitative data.Repeat S11 (being "No" among the S12) when imperfect tense, control part 110 makes to handle and advances to S13 when finishing.
After finishing to the record of this working procedure states DB121, in the data that operation abnormity detection portion 112 writes down from working procedure states DB121, read the production code member data of production code member minimum and the qualitative data (S13) of this product, this product is judged whether to take place unusual (S14).Wherein, operation abnormity detection portion 112 judges that taking place one at least detects each unusual kind when unusual (being "Yes" among the S14), and each abnormal information and production code member data that this unusual product takes place are sent to cause information collection unit 113 (S15).And operation abnormity detection portion 112 is judged (being "No" among the S14) when unusual is not taken place, and makes to handle to advance to S17.
Then, when cause information collection unit 113 receives each abnormal information and production code member data, with reference to unusual/reason corresponding tables 122, read the abnormal cause information corresponding with the combination of this each abnormal information, with the abnormal cause information of reading, with the abnormal cause information of reading set up corresponding process information, and the production code member data recording to unusual/reason DB123 (S16).
And control part 110 judges for all products that write down the production code member data in working procedure states DB121 whether it has carried out the processing of S13 (S17).At this, when 110 pairs of above-mentioned all products of control part are judged the processing of not carrying out S13 (being "No" among the S17),, make to handle to advance to S13 in S13, carrying out increment (S18) as the production code member data of reading the product of object.And, when 110 pairs of above-mentioned all products of control part are judged its processing of having carried out S13, make to handle to advance to S19 (in S17, being "Yes").
Thus, for all products that write down the production code member data in working procedure states DB121, (for the product that substandard products do not take place is S13～S14) can to carry out the processing of S13～S16 successively by each product.Therefore, unusual for all products of certain batch of product, and exist when unusual when detecting, read abnormal cause information unusually according to each, the abnormal cause information of reading can be recorded unusually/reason DB123 in.
And, in S19, frequency data preparing department 114 is with reference to all abnormal cause information that write down among unusual/reason DB123, calculate the various types of record number of abnormal cause information, according to this record number, make the frequency data of the read frequency that has gathered cause information collection unit 113 according to each kind of abnormal cause information.
Further, chart production portion 115 makes the Pareto diagram of the above-mentioned read frequency of each unusual cause information of expression according to the said frequencies data, and this Pareto diagram is shown to display part 105 (S20).Thus, the Pareto diagram shown in Fig. 7 (a) is shown to the operator by display part 105.
Therefore according to said structure, mutually different each is unusual a plurality of unusual for comprising kind for operation abnormity detection portion 112, detects unusual kind respectively.And each is a plurality of unusual for above-mentioned for cause information collection unit 113, with reference to unusual/reason corresponding tables 122 of storage in the storage part 120, reads with the abnormal information of representing above-mentioned detected unusual kind and has set up corresponding abnormal cause information.
Further, frequency data preparing department 114 calculates the various types of read frequency of the abnormal cause information of cause information collection unit 113, and chart production portion 115 will represent that the Pareto diagram of the above-mentioned read frequency of each unusual cause information is shown to the operator.
At this, the abnormal cause information that read frequency is high more can be inferred in above-mentioned production line 1, and it is with a large amount of relevant unusually, can infer that also it is with more multiple relevant unusually.This is because its abnormal cause is also identical sometimes unusually even kind is mutually different.
Therefore, for the operator, the Pareto diagram of the various types of read frequency of the above-mentioned abnormal cause information of referential expression carries out abnormality processing by utilizing the high abnormal cause information of read frequency, can reduce multiple class and a large amount of unusual efficiently.
In addition, in the prior art, shown in Fig. 7 (b), add up each unusual frequency and the demonstration that in production line 1, takes place unusually according to each.That is, " to float " be respectively the unusual kind that takes place in production line 1 to " bridge " " substandard products " among Fig. 7 (b).
But generally speaking, for a kind of unusually also can infer a plurality of abnormal causes, therefore as Fig. 7 (b) shown in,, also can't carry out effectively unusual improvement even determine the occurrence frequency of the unusual kind that in production line 1, takes place.This is because in order to eliminate one unusually, need cause this unusual a plurality of abnormal causes all to check to supposition, and will carry out such inspection unusually to all.
Relative with it, in the present embodiment, the abnormal cause shown in the high abnormal cause information of read frequency is speculated as causes the unusual of a large amount of and multiple class.Therefore by being conceived to the abnormal cause shown in the high abnormal cause information of read frequency and eliminating this abnormal cause, can help to improve efficiently the unusual of a large amount of and multiple class.
For example in the operation field of reality, only be conceived to an abnormal cause information and when only eliminating reason shown in this abnormal cause information, if the above-mentioned read frequency of this abnormal cause information is higher, then be expected once to improve tens of kinds unusual.
In addition, in structure shown in Figure 1, chart production portion 115 is according to the frequency data that receive from frequency data preparing department 114, make the Pareto diagram of the above-mentioned read frequency of each unusual cause information of expression, but be not limited only to Pareto diagram, get final product so long as can discern the different chart of the above-mentioned read frequency of each unusual cause information.Except Pareto diagram, can also be histogram, line chart, circular diagram, table etc. for example.
And also can adopt following structure: the operator is behind input part shown in Figure 11 06 input chart switching commands, and chart production portion 115 switches to other figure (above-mentioned histogram, line chart etc.) with the chart that display part shows from Pareto diagram.
And, in the present embodiment, the above-mentioned read frequency of each unusual cause information is made Pareto diagram, and this Pareto diagram is shown to display part 105, thereby make the operator discern the difference of the above-mentioned read frequency of each unusual cause information, as long as and can make the operator discern the difference of the above-mentioned read frequency of each unusual cause information, be not limited to this Pareto diagram is shown to the processing of display part 105.For example also the piece (notice mechanism) that carries out following processing can be arranged on the control part 110: the above-mentioned read frequency of above-mentioned each unusual cause information is notified to operator's processing by vocal guidance (audioguidance).
In addition, above-mentioned " frequency " also can be except number of times, the number of degrees, also can be ratio, probability etc.
And in structure shown in Figure 1, detect the abnormal information that takes place in the product, calculate read frequency, but this is not limited to the unusual of product generation unusually as the abnormal cause information of this unusual reason.For example also applicable to each manufacturing equipment in the production line 1 take place unusual.In this case, the measurement mechanism that can measure the equipment running status (temperature, processing speed etc.) in the above-mentioned production line respectively with the corresponding setting of each equipment (solder printing device 10, apparatus for mounting component 20, reflux 30).And working procedure states collection unit 111 receives service data as the measured value of the operation conditions of each equipment from each measurement mechanism, with this service data and the while time of reception as the time series data recording in working procedure states DB121.And operation abnormity detection portion 112 detects the unusual and unusual kind that produces in each equipment and gets final product with reference to these time series data.
And in the structure of Fig. 1 also can be: all process steps information corresponding with each the unusual cause information that writes down be read with reference to unusual/reason DB123 by chart production portion 115, according to the kind of each operation, the read frequency of process information is shown to display part 105.At this, Fig. 8 is the example of Pareto diagram of the read frequency of the above-mentioned process information of expression.
Thus, for example, as shown in Figure 8, in a plurality of operations, can show the frequency of the operation relevant,, be easy to the operation of specifying abnormal cause many therefore for the operator by different operations with abnormal cause.
But the optional in the present invention formation of the demonstration of the read frequency of process information.And, when structure is the read frequency that do not carry out process information when showing, unusually/need not to store process information in the reason corresponding tables 122, and unusually/need not to write process information among the reason DB123.
And in structure shown in Figure 1, the operation abnormity detection portion 1 12 of process management device 103 reaches the detection of unusual kind unusually, but its structure also can be the detection that is reached unusual kind by each testing fixture 102 unusually.In this case, be provided with operation abnormity detection portion 112 in each testing fixture 102, testing fixture 102 will represent that the abnormal information of unusual kind and this production code member data that this unusual product takes place send to process management device 103 jointly.
And in the Working procedure management system 100 of present embodiment, a plurality of testing fixtures 102 are to set up corresponding form setting respectively with a plurality of manufacturing equipments (a plurality of operation), and this testing fixture need not to be provided with a plurality of, and is also single.This be because, when only a manufacturing equipment in a plurality of manufacturing equipments being provided with pick-up unit 102, in this testing fixture 102, may detect diverse a plurality of unusual to certain product, by being suitable for the process management device 103 of present embodiment, be expected to improve efficiently a large amount of and multiple unusual.In a word, so long as can detect diverse a plurality of unusual operation field, can irrespectively be suitable for the process management device of present embodiment with process number, number of devices.For example, in the production line of printed base plate, only in solder printing operation (solder printing device), " scolding tin is too much " " dislocation " can take place a product.
Therefore, in the present embodiment, process management device 103 is management a plurality of operations (solder printing operation, parts installation procedure, reflow process) and detects the various unusual structure that a plurality of operations produce, and also can be single process management or the unusual structure that detects single operation generation.
Further, in above embodiment, calculate the various types of above-mentioned read frequency of abnormal cause information, and the Pareto diagram of demonstration different normal cause information of expression and above-mentioned read frequency, and for the lower operator of proficiency, even watch this abnormal cause information and read frequency, also can't understand sometimes in order to eliminate abnormal cause and how to handle.This is because the operator low for proficiency only knows abnormal cause can't understand for eliminating this abnormal cause to take what kind of measure.
Therefore, its structure also can be in the process management device 103 of present embodiment: substitute abnormal cause information, the process information of the disposal route of storage representation abnormal cause is read process information according to detected abnormal information.This process information is the information of expression to the disposal route of abnormal cause.For example, an abnormal cause as for unusual " scolding tin is too much " or " scolding tin is very few " comprises " mask contamination ", and comprises " cleaning mask " " modification operation or work standard " as the process information for this abnormal cause " mask contamination ".And an abnormal cause as for unusual " no parts " comprises " spray nozzle clogging ", and comprises that as the process information for this abnormal cause " spray nozzle clogging " " replacing nozzle " " adjust frequency of maintenance " (with reference to Fig. 3, Figure 11) again.
Below the process management device 103 that uses above-mentioned process information is described.The FBD (function block diagram) of the process management device 103 when Fig. 6 is to use above-mentioned process information.And, in Fig. 6, be marked with and the identical reference marks of each parts of Fig. 1, and omit its explanation for playing with the parts of Fig. 1 same function.
In process management device 103 shown in Figure 6, be with the difference of the structure of Fig. 1: in storage part 120, do not store unusual/reason corresponding tables 122 and storage unusual/handle corresponding tables 126, do not store unusual/reason DB123 and store unusual/handle DB127.And has following difference: do not have cause information collection unit 113 in the control part 110 and have process information collection unit (sense station) 116.
Shown in Figure 6 unusual/handle corresponding tables 126 and be the combination, the process information of representing the disposal route of the reason that this is unusual that will expression generate the abnormal information of the unusual kind that takes place in the line 1, specify the process information of the operation that produces this unusual reason to set up corresponding table.
In addition, there is not to illustrate the content of unusual/processing corresponding tables 126 at this, but and the difference of unusual/reason corresponding tables 122 only is to replace abnormal cause information with process information in respectively the walking crosswise of Fig. 3, other aspects with unusual/reason corresponding tables 122 is identical construction.
At this, process information collection unit 116 shown in Figure 6 according to each product when operation abnormity detection portion 112 receives each abnormal information and production code member data, with reference to unusual/processing corresponding tables 126, read the process information corresponding with the combination of each abnormal information that receives according to each product.
Further, with process information collection unit 116 according to each product will from unusually/handle process information that corresponding tables 126 reads, unusually/handle the corresponding tables 126 with this process information set up corresponding abnormal information and process information and production code member data recording to unusually/processing DB127.
Therefore, unusually/handle among the DB127 recording according to each product: be illustrated in the disposal route of the unusual reason that takes place in this product process information, set up corresponding abnormal information (promptly being illustrated in the abnormal information of the unusual kind that takes place in this product) and set up corresponding process information (that is the information of the operation of definite this unusual reason of generation) with this process information with this process information.
According to the structure of Fig. 6, frequency data preparing department 114 is with reference to unusual/processing DB127, according to each kind computing recording of information number of process information.And frequency data preparing department 114 makes the various types of various types of read frequency of number as the process information of process information collection unit 116 that respectively write down of process information to gather the frequency data of this read frequency, and sends to chart production portion 115.
Further, chart production portion 115 is shown to display part 105 according to the Pareto diagram of the various types of read frequency of the process information of this frequency data making expression process information collection unit 116 with this Pareto diagram.Therefore as long as the operator is with reference to this Pareto diagram and utilize the high process information of read frequency to improve processing unusually, is expected to improve efficiently a large amount of and multiple unusual.
And, thus, not only show the abnormal cause information of only representing abnormal cause, and show the process information of the disposal route of this abnormal cause of expression, thereby even the low operator of proficiency also can understand the corresponding method of abnormal cause really.
Usually, when unusual countermeasure was handled in execution, at first according to the unusual supposition abnormal cause that takes place, abnormal cause by inference imported disposal route afterwards, therefore shown in the structure of Fig. 6, can think that also it is factitious reading process information from detected abnormal information.But, show that sometimes concrete disposal route is better than display abnormality reason, so the structure of Fig. 6 also there is suitable situation according to the difference of operator's proficiency.
But under the structure of Fig. 6, do not show Pareto diagram, and show Pareto diagram,, can't know the reason (abnormal cause) of why taking the processing shown in this process information therefore for the operator based on process information based on abnormal cause information.Therefore, can consider to show Pareto diagram, and further show structure based on the Pareto diagram of process information based on abnormal cause information.For this structure, carry out following explanation with reference to the block diagram of Figure 10.In addition, in Figure 10, for paying and the identical reference marks of parts among Fig. 1, and omit its explanation with the parts that Fig. 1 has an identical function.
The process information of the disposal route that reason/processing corresponding tables 128 is the abnormal cause information that makes the unusual reason that expression takes place in the production line, represent this abnormal cause and set up the corresponding corresponding table of process information foundation with this process information.
Figure 11 carries out illustrative figure to the memory contents of reason/processing corresponding tables.In the reason/processing corresponding tables 128 of this example, " mask contamination " put down in writing in each file " it is slow that scolding tin is changed " " mask is fixing bad " ... be respectively abnormal cause information, " cleaning mask " " replacing scolding tin " " modification operation or work standard " of record in respectively walking crosswise ... be respectively process information.
And the same with Fig. 3, the corresponding relation of abnormal cause information and process information is by being represented by above-mentioned each file and the circular mark of respectively walking crosswise each frame that constitutes.For example, if when being conceived to abnormal cause information " mask contamination ", be to belong to walking crosswise of " mask cleaning " " modification operation or work standard " with corresponding the walking crosswise of frame of having put down in writing circular mark in the file of this " mask contamination ".That is, the such abnormal cause information of abnormal cause information " mask contamination " and " mask cleaning " " modification operation or work standard " has been set up corresponding.
In the structure of Figure 10, at first, control part 110 is carried out each step shown in Figure 9, will be shown to display part 105 based on the Pareto diagram of abnormal cause information.Afterwards, after process information collection unit 117 in the control part 110 receives order (reading the order of process information) from input part 106, according to unusually/all abnormal cause information of all products of writing down among the reason DB123, with reference to reason/processing corresponding tables 128, read the process information corresponding successively with each unusual cause information.Further, each process information that will read successively of process information collection unit 117 is input to frequency data preparing department 114.
And the frequency data preparing department 114 of Figure 10 is for the input number of the process information of importing successively according to the various types of computing information of process information.And frequency data preparing department 114 makes the various types of input number of the process information various types of read frequency as the process information of process information collection unit 117 to gather the frequency data of this read frequency, and sends to chart production portion 115.
Further, chart production portion 115 is shown to display part 105 according to the Pareto diagram of the various types of read frequency of the process information of this frequency data making expression process information collection unit 117 with this Pareto diagram.At this, as long as the operator is with reference to this Pareto diagram and utilize the high process information of read frequency to improve processing unusually, is expected to improve efficiently a large amount of and multiple unusual.
And,, behind the Pareto diagram that shows based on abnormal cause information, show Pareto diagram based on process information according to the structure of Figure 10.Therefore for the operator, can be to high-frequency abnormal cause information and high-frequency process information in conjunction with knowing, thereby can to the abnormity processing method, and the reason (abnormal cause) that adopts this disposal route in conjunction with holding.
In addition, more than shown in unusual/reason corresponding tables 122, reason/processing corresponding tables 128 in Fig. 3 and example shown in Figure 11, write down process information, but also can not write down process information.
