BACKGROUND OF THE INVENTION
The present invention relates to a component mounting apparatus that mounts electronic components on a printed circuit board, and more particularly to a component mounting apparatus that can freely set a delimiter in production performance data.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is an electronic component mounting apparatus that mounts an electronic component (hereinafter simply referred to as a component) on a printed circuit board (hereinafter simply referred to as a substrate) carried into the main body device.
FIG. 7 (a) is an external perspective view of such an electronic component mounting apparatus, and FIG. 7 (b) is a perspective view schematically showing the internal configuration by removing the upper and lower protective covers.
[0003]
As shown in FIG. 1 (a), the electronic component mounting device 1 includes a monitor device 2 composed of a CRT display before and after the ceiling cover, and alarm lamps for notifying the operation state on the left and right sides of the ceiling cover. 3 is provided. In addition, on the front and rear surfaces of the upper protective cover 4, a small display input panel 5 which is composed of a liquid crystal display and a touch input device and can input various instructions by external operation is disposed. (The display input panel 5 at the rear in the upper right direction in the figure is shaded and cannot be seen).
[0004]
On the lower base 6, a pair of parallel and fixed board guide rails 7 are fixed and movable in the center, and the printed circuit board (hereinafter simply referred to as a board) 8 shown in FIG. It extends horizontally in the axial direction (from the diagonally lower right to the diagonally upper left). A loop-shaped conveyance belt (conveyor belt) that is not visible in the drawing is disposed so as to be in contact with the lower part of the board guide rails 7.
[0005]
The conveyor belt is driven by a belt drive motor (not shown) with the side of the belt having a width of several millimeters seen from below the substrate guide rail 7 into the substrate conveyance path, and runs in the substrate conveyance direction. The board 8 before component mounting is carried into the apparatus main body from the upstream side of the line while supporting the board from below, and the board 8 on which the components are mounted is sequentially carried out to the downstream side of the line. In the electronic component mounting apparatus 1, two substrates 8 are always carried in, positioned, and fixed until the component mounting is completed.
[0006]
Electronic component supply bases 9 are respectively formed on the front and rear sides of the base 6 (in FIG. 5A, the rear electronic component supply base 9 which is obliquely upward to the right in the figure is hidden and cannot be seen. (B), the rear electronic component supply base 9 is not shown). A large number of tape cassette type electronic component supply devices 11 (hereinafter referred to as tape feeders) are arranged on the electronic component supply base 9.
[0007]
Above the base 6, there are two X-axis rails 12 and a Y-axis supported on the X-axis rails 12 so as to be slidable in the X-axis direction (from the lower right to the upper left). Rails 13 are arranged on the left and right, respectively, and two work head support towers 14 are suspended on each Y-axis rail 13 so as to be slidable in the Y-axis direction (from the diagonally lower left to the upper right in the figure). Has been. That is, a total of four work head support towers 14 are arranged in the electronic component mounting apparatus 1 shown here.
[0008]
In the example shown in the figure, two work heads 15 are arranged on each work head support tower 14 so as to be movable up and down (Z direction) and rotatable in a 360 degree direction (referred to as the θ direction). That is, a total of eight work heads 15 are arranged in the electronic component mounting apparatus 1, and each work head 15 moves in the X-axis direction by the Y-axis rail 13, and the Y-axis direction by the work head support tower 14. , And movement in the Z-axis direction by the work head 15 itself and rotation in the θ direction, the position in the front-rear, left-right, up-down, and 360-degree directions can be freely controlled.
[0009]
These work heads 15 suck a predetermined component supplied to the suction unit by the tape feeder 11 or the tray-type electronic component supply device by a suction nozzle and mount the sucked component on a predetermined mounting position of the substrate 8. .
The base 6 is provided with a substrate positioning device, a substrate fixing mechanism for fixing the substrate between the two substrate guide rails 7, a control device for controlling each part, etc., although not particularly shown. ing.
[0010]
FIG. 8 is a perspective view of the tape feeder 11 disposed on the electronic component supply base 9. Usually, 50 to 70 tape feeders 11 are attached to the electronic component supply base 9 depending on the size of the component mounting apparatus 1 and the size of the components to be supplied. That is, when the front and rear electronic component supply bases 9 are combined, 100 to 140 tape feeders 11 are arranged in one component mounting apparatus 1.
[0011]
The electronic component supply base 9 is provided with a large number of mounting and fixing holes 16 at the front and rear, and the tape feeder 11 as shown in FIG.
In the tape feeder 11, a component tape containing a component is wound around the component reel 17, and the component tape is pulled out to the component supply port 18 and separated into a top tape 19-1 and a storage tape 19-2. Then, the components accommodated in the accommodation tape 19-2 are exposed to the component supply port 19. The exposed component is taken out by the work head 15 of the component mounting apparatus 1 with a suction nozzle or a gripping chuck and mounted on the substrate 8.
[0012]
FIG. 9 is a diagram showing an example of a board unit production line on which such an electronic component mounting apparatus 1 is arranged. In the example shown in the figure, four substrate unit production lines are shown, and a reflow furnace 20 for fixing components mounted on the substrate onto the substrate is disposed at the end of each line. In addition, a substrate supply device is actually arranged at the beginning of each line, but is not shown in the figure.
[0013]
In the first production line shown in the upper right of the figure, two electronic component mounting apparatuses 1 are connected in series to the production line, and in the next second production line, one electronic component mounting apparatus 1 is manufactured. On the upstream side of the line, one dispenser 21 for attaching or applying paste-like solder or the like is arranged in series on the production line. The dispenser 21 may be disposed on the upstream side of the production line of the electronic component mounting apparatus 1 or may be disposed on the downstream side depending on the type of electronic component mounted on the board unit to be manufactured. Moreover, the production line in which the dispenser 21 is not disposed is usually a case where a dispenser function is added to the electronic component mounting apparatus 1 of the production line. Each device in each of these production lines is connected to the host management device 22 by a signal line 23 to manage the operating state.
[0014]
Such an electronic component mounting apparatus 1 records production record data such as the number of production boards, the number of component adsorptions, the number of component adsorption errors, and the operation time in a memory built in the main unit and holds it. . Then, after the production is completed, the host management device 22 reads the production result data from the memory of each electronic component mounting device 1 and calculates the operation rate, the component suction rate, the suction error rate, etc., and the operation of each electronic component mounting device 1 The condition was evaluated.
[0015]
By the way, these production results data are obtained from the start to the end of the production of one type of substrate, that is, at every change of the production program, or from the shift takeover time of shift work to the next changeover time (one assigned time zone). The production unit data is divided as one production unit, and the production result data recorded in the memory of the main unit is divided for each division.
[0016]
Therefore, to evaluate how the status of the main unit has changed before and after fine-tuning the operating conditions during production, display the actual production data before fine-tuning from the memory on the display device. After writing on the memo paper, the production result data is manually cleared, production after fine adjustment is started, and new production result data is aggregated.
[0017]
Then, after operating for a predetermined time or after producing a predetermined number of sheets, the production result data is displayed on the display device from the memory, and the operation condition is compared with the production result data before fine adjustment written on the memo paper. The work of evaluating the state of change of the main unit before and after fine-tuning was performed.
[0018]
For example, if there is a part with a poor suction rate, change the tape feeder used for that part to another tape feeder or change the settings of the parts master table, and make fine adjustments. When confirming the results, it was a work form in which the data on the component suction rate so far was written on a memo paper, the production result data so far was cleared, and then the data on the subsequent suction rate was retaken.
[0019]
[Problems to be solved by the invention]
By the way, when there is a change such as a decrease or improvement in productivity at a board production plant, for example, the manufacturer of the component mounting device receives a report of this change and tries to analyze the cause. In this case, since the production result data is cleared during the production in order to add new data as described above, the substrate production factory can extract only the latest data. Therefore, since it was impossible to analyze the production results retroactively, there was dissatisfaction that it was not possible to take time to analyze the cause of the change and immediately improve the component mounting apparatus.
[0020]
In view of the above-described conventional situation, an object of the present invention is to provide a component mounting apparatus in which an operator can arbitrarily set a division of production results, and display or totalize production results in the division unit. It is to be.
[0021]
[Means for Solving the Problems]
The configuration of the electronic component mounting apparatus according to the present invention will be described below.
The electronic component mounting apparatus according to the present invention is an electronic component mounting apparatus that mounts electronic components on a printed circuit board. Separation setting means for setting arbitrary divisions in production result data, and production results for each division set by the division setting means. Display means for displaying data.
[0022]
The electronic component mounting apparatus further includes, for example, a tabulating unit that tabulates data for each of a plurality of production result items for each production result data for each partition set by the partition setting unit. The display means is configured to display data for each production result item aggregated by the aggregation means.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
The electronic component mounting apparatus in the embodiment of the present invention is the same electronic component mounting apparatus as shown in FIGS. 7 (a) and 7 (b). However, the processing operation of the control unit disposed inside the base is different. In this example, the control unit is not particularly shown, but a central processing unit (CPU) and a read only memory (ROM), a random access memory (RAM), an image processing unit, and an I / O connected to the CPU via a bus. (I / O) interface, etc. The I / O interface includes an input monitor, key input unit, servo motor, positioning device, abnormality notification lamp, HD (hard disk) and other external storage devices, area sensor, limit sensor A substrate sensor or the like is connected. The input monitor has a display input function similar to that of the display input panel 5 shown in FIG.
[0024]
The CPU generates a data record called “production packet” as a minimum unit for collecting production performance data in the processing specific to this example, and stores this in a memory format such as RAM or a recording medium such as HD in the form of a database. Like to do.
FIG. 1A is a diagram showing a data configuration of the production packet, and FIG. 1B is a diagram showing a data configuration of a data record of pick information linked to the production packet by a packet code. .
[0025]
As shown in FIG. 1A, the production packet 25 includes a packet code 25-1, a model code 25-2, a start time 25-3, an end time 25-4, a setter 25-5, and a comment 25-6. , Composed of six data areas. The production packet 25 is normally automatically generated by the control device for each type (type) of board to be produced or for each change of one assigned time zone. Further, the production packet 25 can be forcibly divided and generated by an operator as will be described in detail later, if necessary.
[0026]
Also, as shown in FIG. 4B, the pick information 26 is composed of four data areas: a packet code 26-1, a feeder number 26-2, a pick number 26-3, and an error number 26-4. Yes.
FIG. 2 (a) is a diagram showing an example of a data table composed of the production packet 25, and FIG. 2 (b) is a diagram showing an example of a data table composed of the pick information 26. .
[0027]
In the example of the production packet data table shown in FIG. 2A, five data records of the production packet are formed. In the data table of FIG. 5A, for each data record of the production packet, the data number of packet code 25-1 is stored with packet numbers 1, 2, 3, 4, 5 in ascending order in time series. ing. In the data area of the model code 25-2, a code indicating the model of the board produced in the production packet is stored.
[0028]
Also, the data area of the start time 25-3 stores the time when data collection is started in the production packet, that is, the time data of the start of production of a new model board or the restart of production after fine adjustment. Yes. In the data area of the end time 25-4, the time when the data collection in the production packet is completed, that is, the time when the production of the substrate is finished or the time data when the production is interrupted for fine adjustment is stored. ing.
[0029]
In the data area of the setter 25-5, if this production packet is automatically set by the control device, “SYSTEM” is stored as the setter name and is forced by the operator instead of automatically. If it is set automatically, the name of the worker is stored by input, for example, “○ Hayashi ▽ O”. This forced setting of the production packet will be described later.
[0030]
In the data area of the comment 25-6, the reason why the production packet is forcibly set in the case of the production packet forcibly set by the operator as described above is, for example, “master adjustment”. And stored by key input. The master is a component data master.
[0031]
In the example of the pick information data table shown in FIG. 2B, the pick information data record in which the packet code in the data area of the packet code 26-1 is “1” has the packet code “1”. This is a data record of pick information 26 corresponding to the production packet 25, and this data record has two lines in the example shown in FIG.
[0032]
In the data area of feeder number 26-2 of these two rows of data records, numerical values “10” and “20” indicating the 10th tape feeder and the 20th tape feeder are stored, respectively. As the pick information of the No. 10 tape feeder, a numerical value “200” indicating the number of picked-up parts is stored in the data area of the pick number 26-3, and the data area of the error number 26-4 is stored in the data area. A numerical value “18” indicating the number of parts recognition errors is stored.
[0033]
Also, in the data record on the second line of the pick information corresponding to the production packet of the same packet code “1”, the number of picked-up parts in the data area of the number of picks 26-3 as pick information of the 20th tape feeder A numerical value “100” indicating the number of component recognition errors is stored in the data area of the error number 26-4.
[0034]
Hereinafter, in each data record of pick information corresponding to the production packets of the packet codes “2” to “5”, data is stored in the same manner as described above.
Here, the production packet generation form will be described again for confirmation. The production packet is defined as follows. (1) One production packet is defined from the start to the end of the production of one board type. (2) However, when there is a change of one assigned time zone during production, the production packet is divided by the change time. (3) The production packet can be forcibly separated by the worker during production. In this example, the production packet is defined in this way. Further, in this example, as described above, the operator forcibly dividing the production packet is referred to as “inserting a bookmark”.
[0035]
FIG. 3 is a flowchart of a process in which the control device constructs the production packet and pick information database having the above configuration in the built-in memory using the bookmark insertion function. In the figure, when production is started, a new production packet is generated as an initial setting, the current time is set in the data area of the start time 25-3 of the data record, and the data area of the setter 25-5 is further set. “SYSTEM” is stored in (step S01).
[0036]
Subsequent to the above initial setting, one board is produced (step S02). This process is a normal production process in which predetermined parts are sequentially mounted on a board to produce a board unit. Further, the pick information of the number of successful pick-ups and the number of unsuccessful pick-ups of parts during this time is temporarily recorded in a predetermined area of the memory.
[0037]
Next, it is determined whether or not the switching is direct (one assigned time zone is referred to as “direct” in this example) (step S03). In this process, for example, in the case of a two-part shift system from time 9:00 to 18:00 and from time 18:00 to 3:00, time 18:00 and time 3:00 are direct switching.
[0038]
If it is not a direct switching in the above determination (No in S03), it is then determined whether bookmark setting is set (step S04). In this process, the operation of the electronic component mounting apparatus main body is stopped by the stop operation of the stop button by the operator, and it is determined whether or not the insertion of the bookmark is instructed by the operator on the bookmark insertion operation screen described later. It is.
[0039]
When insertion of a bookmark is not instructed (No in S04), it is further determined whether or not production is finished (step S05). This process is a process for determining whether or not the number of produced board units has reached the production number designated at the start of the initial production.
[0040]
If the production number of the substrate units has not yet reached the production number designated at the beginning of production (S05 is No), the process returns to step S02 and the processes of steps S02 to S05 are repeated. . As a result, the number of board units produced is the number specified at the start of production, and pick information between them is sequentially recorded in the memory.
[0041]
In step S05, when the production number of the board unit reaches the production number designated at the beginning of the initial production (S05 is Yes), the current production packet end time 25-4 is currently displayed in the data area. Time data is stored and stored in the database together with the pick information recorded in the memory (step S06). Thereby, (1) one production packet from the start to the end of the production of one type of substrate is generated.
[0042]
If the result of the determination in step S03 is a direct change (Yes in S03), the current time data is also stored in the data area of the end time 25-4 of the current production packet and stored in the memory. It is stored in the database together with the recorded pick information (step S07). Then, a new production packet is generated at the next production start. As a result, (2) when there is a direct switching during production, the production packet is divided at the switching time.
[0043]
If it is determined in step S04 that insertion of a bookmark is instructed (S04 is Yes), the current time data is first stored in the data area of the end time 25-4 of the current production packet in this case as well. Then, it is stored in the database together with the pick information recorded in the memory (step S08). As a result, (3) the production packet is forcibly separated by the operator even during production.
[0044]
FIG. 4 is a diagram showing an example of a bookmark insertion display screen when a production packet is forcibly divided by an operator as described above. The display screen for inserting a bookmark is displayed on an input monitor provided in the electronic component mounting apparatus of this example.
A display screen 27 for inserting a “bookmark” shown in FIG. 4 is used when a worker forcibly separates a production packet during production of a board unit, and performs a stop operation on a stop button provided on the electronic component mounting apparatus. By stopping the operation of the electronic component mounting device and selecting the “Set bookmark for production performance” tool from the “Tools” on the production screen displayed on the input monitor, the display of the production screen will be displayed. The display switches to the bookmark insertion display screen 27 in FIG.
[0045]
That is, this bookmark insertion function does not operate during production of the board unit, and functions only after the electronic component mounting apparatus is stopped.
As shown in FIG. 4, the bookmark insertion display screen 27 displays “Do you want to put a production bookmark” on the uppermost display section 28, and the worker display section 29 displays “worker”. An operator name input window 30 is displayed on the right of the display, and a pull-down menu button 31 with a downward ▽ mark is displayed on the right end of the operator name input window 30.
[0046]
When this pull-down menu button 31 is touched, a work name registered in advance is displayed in the pull-down menu. By selecting his / her name from the pull-down menu, the worker can display his / her name in the worker name input window 30 and confirm the input of the name. As a result, the main device stores who and what time the bookmark is entered in the production packet.
[0047]
In addition, a comment input window 33 is displayed on the right side of the “comment” display in the comment display portion 32 below the worker display unit 29. The operator key-in a comment indicating the reason for dividing the current production packet by inserting a bookmark into the comment input window 33.
[0048]
A “Yes” button 34 and a “No” button 35 can be displayed below the comment input window 33. Using these buttons, the input data can be corrected, canceled, or confirmed.
In this way, the insertion of the bookmark is designated on the bookmark insertion display screen 27, and the name of the worker who made the designation and the comment indicating the reason are input, so that the process of step S08 in FIG. 3 is performed. Subsequently, the control device generates a new production packet 25, sets the current time in the data area of the start time 25-3 of the production packet 25, and inserts the bookmark into the data area of the setter 25-5. The operator name input on the display screen 27 is stored, and the comment input on the display screen 27 for inserting a bookmark is stored in the data area of the comment 25-6. Return to, and resume production of the board unit that was suspended.
[0049]
In this way, the production packet can be forcibly divided by the worker during production. For example, when teaching is performed during production and the picking conditions are changed by this teaching and resume production, teaching is performed. It is possible to easily compare how the pick rate has been improved before and after changing the picking conditions by separating the production packets before and after.
[0050]
The above-described production packet data table shown in FIG. 2 (a) is generated by the above-described processing of FIG. 3 when the board unit is produced immediately between 9:00 and 18:00. A production packet is shown.
As shown in FIG. 2 (a), two types of model codes, PCB-A and PCB-B, are produced in this series. Then, in the production of the substrate unit whose model code is PCB-A, the production start-end is performed twice, and the bookmark is inserted once during the first production start-end. Thus, three production packets are generated in the production of the board unit whose model code is PCB-A. Further, in the production of the board unit whose model code is PCB-B, two production packets are generated, no bookmark is inserted, and normal production start to end.
[0051]
In the example shown in FIG. 2 (a), for example, when the base unit is produced by the production packet of the packet code “1”, automatic teaching is performed during operation, and a bookmark is inserted to analyze the results before and after the packet. An example is shown in which a production packet of code “2” is generated.
[0052]
In this example, a production performance display screen is used, and information can be displayed on the screen of the input monitor for production instruction units by the production packet as described above. Taking the example of the above five production packets as an example, in production in units of manufacturing instructions shown in FIG. 2 (a), if the model code PCB-A is designated on the input monitor screen, the packet codes 1, 2 , 4 can be aggregated and displayed on the input monitor screen.
[0053]
It is also possible to specify only one production packet and view data such as pick information of the production packet. It is also possible to select “all” and totalize and display all production packets as necessary.
FIG. 5 is a flowchart of the display process by the CPU when the production packet data is displayed on the input monitor screen as described above.
[0054]
FIGS. 6A to 6E are diagrams showing examples of display screens displayed on the input monitor screen in the above display processing.
In the flowchart of FIG. 5, first, the value of the output variable is initialized, and an initial screen as shown in FIG. 6A is displayed (step S001). In this process, the operator selects and inputs a desired model name from the model names called by the model menu button 38 in the model name column 37 of the display screen 36. In the example shown in FIG. 5B, the model code “PCB-A” of the board unit is selected and input in the model name column 37.
[0055]
In addition, a desired production packet is selected and input from the production packets called by the packet button 41 to the production packet column 39 of the display screen 36 by the operator. In the example shown in FIG. 5B, “all” is selected and input in the production packet column 39.
[0056]
Based on these input data, in FIG. 5, the CPU searches the DB to read one production packet 25 shown in FIG. 1A from the DB (database) (step S002).
Then, it is determined whether or not the production packet 25 is recorded in the DB and read (S003). If the production packet 25 is read (Yes in S003), the production packet 25 that has been read is subsequently read. Whether the model code stored in the data area of the model code 25-2 is the same as the model code “PCB-A” entered as shown in FIG. 6B on the initial screen of FIG. Is determined (step S004).
[0057]
If the model codes are the same (S004 is Yes), the time data stored in the data area of the start time 25-3 of the production packet 25 is further displayed on the initial screen of FIG. It is determined whether or not the time is equal to or greater than “9:00” of the input start time Ik set as in (b) (step S005). In this determination, it is also determined whether or not the start time Ik is “0:00”.
[0058]
If the time data stored in the data area of the start time 25-3 is not less than “9:00” of the open time Ik when the time data is input, or if the start time Ik is “0:00”. Since this is a production packet whose production has started in the specified time zone (S005 is Yes), in this case, the time data stored in the data area of the end time 25-4 of the production packet 25 is next. In the initial screen of FIG. 6A, it is determined whether or not the input end time Is set as shown in FIG. 6B is equal to or less than “18:00” (step S006). . In this determination, it is also determined whether or not the end time Is is “0:00”.
[0059]
If the time data stored in the data area of the end time 25-4 is less than or equal to “18:00” of the input end time Is, or the end time Is is “0:00”. In this case, since the production packet has been produced in the specified time zone (Yes in S006), in this case, the start time and the end time for display output for the next data aggregation and display Update.
[0060]
That is, following the above, first, it is determined whether or not the time data of the start time 25-3 of the production packet 25 is smaller than the input start time Ok (step S007). This process is for examining the start time of the actual production period. Here, the start time 25-3 of the production packet 25 read in step S002 is compared with the output start time Ok to produce a production packet. If it is older (YES in S007), in this case, the start time of the production packet 25 is set to the output start time Ok (step S008), and the process proceeds to step S009.
[0061]
On the other hand, when the start time of the production packet 25 is not older than the output start time Ok (NO in S009), the process immediately proceeds to step S009.
Following the above, it is next determined whether or not the time data of the end time 25-4 of the production packet 25 is greater than the output end time Os (step S009). This process is for checking the end time of the actual production period. Here, the end time 25-4 of the production packet 25 is compared with the output end time Os, and if the production packet is newer ( S009 is YES), the end time of the production packet 25 is set to the output end time Os (step S010), and the process proceeds to step S011.
[0062]
On the other hand, if the end time of the production packet 25 is not newer than the output end time Os (S010 is NO), the process immediately proceeds to step S010.
Then, the number of picks of the production packet and the number of errors are added and displayed (step S011). In this process, a packet code that matches the packet code in the data area of the packet code 25-1 of the production packet 25 is stored in the data record of pick information stored in the data area of the packet code 26-1 (FIG. 1 (a), (b) is read out from the pick information data table shown in FIG. 2B, and the number of picks and the number of errors are added.
[0063]
Although “PCB-A” is displayed in the model name column 37 of the display screen 36 shown in FIGS. 6 (c) to 6 (e), the production packet column 39 is shown in FIG. 2 (a). The production packet with the packet code No. 2 is selected and input. In this case, a packet designation field 44 is provided between the production packet field 39 and the start / end time field 42.
[0064]
In the packet designation field 44, “single unit”, “before” and “after” are displayed, and a check input round window is displayed on the left side of each. In the example shown in (c) of the figure, the check input round window on the left side of the “single” is checked, so that the total number of picks, number of errors, and error rate of the production packet of packet code 2 are Displayed for each number.
[0065]
Further, in the example shown in FIG. 6 (d), the check input round window on the left side of “previous” is checked, so that the total number of picks of the production packet immediately before the production packet of the packet code No. 2, The number of errors and error rate are displayed for each feeder number. The data of the production packet immediately before shown in FIG. 6 (d) is the data of the production packet that has been subjected to the automatic teaching during operation as described above, and the data of the production packet of the packet code No. 2 shown in FIG. 6 (c). Is data of a production packet divided by insertion of a bookmark after the above-described automatic teaching during operation.
[0066]
Further, in the example shown in FIG. 6 (e), the check input round window on the left side of “after this” is checked, and as a result, the model code “PCB-A” including the production packet of the packet code No. 2 is entered. The total number of picks, the number of errors, and the error rate of each production packet are displayed for each feeder number. The production packet data shown in FIG. 6 (e) is the data of the production packet of the packet code No. 4 shown in FIG. 2 (a).
[0067]
In this way, by changing the production results before and after fine adjustment, only by inserting a bookmark, the production packet is divided before and after fine adjustment, and the total number of picks and their error rate are displayed. These can be easily analyzed and evaluated in a corresponding manner.
[0068]
【The invention's effect】
As described above, according to the present invention, the operator can put a break in the production performance data at an arbitrary timing, so that the production performance can be initialized at the time of fine adjustment of the main unit, etc. There is no hassle of storing the history of production results before fine adjustment on memo paper or portable recording media such as FD, etc., making it easy to compare and analyze production result data before and after fine adjustment. Can be quickly evaluated.
