By the way, it may be necessary to perform another work in the middle of the job creation work, the necessary information for completing the work may not be available, or the end time may be reached. In such a case, the job creation work will be interrupted, but when restarting after that, it is necessary for the worker to decide from which step to restart by checking the worker's memory and setting contents. There is. Therefore, it may take a lot of time to suspend and then restart the job creation work, which is not efficient.

The present invention has been made in view of such problems, and an object of the present invention is to efficiently resume interrupted work.

The present invention is a work processing support method for supporting work processing using a computer.
(A) The computer divides the work into a plurality of steps and displays them on the display means, and visualizes and displays the steps currently being processed by the operator as the steps being processed on the display means.
(B) When the worker requests the interruption of the work, the computer stores the step of the work for which the processing has been completed in the storage means as the processed step.
(C) When the worker requests the resumption of the work, the computer divides the work into the plurality of steps and displays the work on the display means, reads the processed step from the storage means, and performs the processing. The next step of the completed step is visualized and displayed on the display means as a processing step.
It is a thing.

In this work processing support method, the work is divided into a plurality of steps and displayed, and the step currently being processed by the worker is visualized and displayed as a step being processed. Therefore, the operator can easily visually understand which step of the work consisting of a plurality of steps is currently being processed. Also, when the worker resumes the interrupted work, the next step of the processed step is visualized and automatically displayed. Therefore, it is not necessary for the operator to confirm and determine which step to restart from by checking his / her own memory and setting contents, and the interrupted work can be restarted efficiently.

In the work processing support method of the present invention, the storage means stores a predetermined step among the plurality of steps as a step having a high processing frequency, and in the (c), the computer has a plurality of the work. It is determined whether or not all the processing of the steps has been completed, and if it is an affirmative determination, the predetermined step is read from the storage means and visualized and displayed on the display means, and if it is a negative determination, it is determined. The next step of the processed step may be visualized and displayed on the display means as a processing step. When the worker resumes the work in which all the processes of a plurality of steps have been completed, the already completed steps are often improved so as to obtain better results. The steps in which such improvements are made are frequently processed. Here, when the worker restarts the work for which all the processing has been completed, a predetermined step having a high processing frequency is displayed, so that the worker can efficiently execute the improvement work. When there are a plurality of steps with high processing frequency, the plurality of steps may be visualized and displayed in a state in which the operator can select them.

In the work processing support method of the present invention, in the above (b), when the worker requests the interruption of the work, the computer has previously input the step of the work for which the processing has been completed. It is stored in the storage means as a processed step in association with the identification information of the person, and in the above (c), when the worker requests the resumption of the work and the identification information is input, the computer causes the work. Is divided into the plurality of steps and displayed on the display means, the processed step associated with the identification information is read from the storage means, and the next step of the processed step is set as the processing step. It may be displayed on the display means. By performing personal authentication using the worker's identification information in this way, even if multiple workers with different work progress are using the same computer, appropriate steps are being processed for each worker. Displayed as a step. Therefore, no matter which of the plurality of workers resumes the work, the interrupted work can be efficiently resumed.

In the work processing support method using the identification information of the worker as described above, the computer identifies a predetermined step among the plurality of steps based on the actual processing frequency of the worker having the identification information. It is stored in the storage means as a step having a high processing frequency in association with the information, and in the (c), the computer determines whether or not all the processing of the plurality of steps of the work is completed. If the determination is affirmative, the predetermined step associated with the identification information is read from the storage means and visualized and displayed on the display means. If the determination is negative, the next step after the processed step. The step may be visualized and displayed on the display means as a step being processed. When multiple workers use the same computer, the steps with high processing frequency, that is, the steps for performing improvement work, may differ from worker to worker. Here, when a worker restarts the work for which all the processing has been completed, a predetermined step with a high processing frequency associated with the worker is displayed, so that any of a plurality of workers restarts the work. Even if it does, the improvement work can be carried out efficiently.

In the work processing support method of the present invention, the work includes creating a job for mounting parts on a board, production analysis for improving the work of mounting parts on a board, and mounting parts on a board. It may be a component replenishment work when creating data related to the above or mounting a component on a board. Since such work is often completed while being interrupted and then restarted, it is of great significance to apply the present invention.

The Y-axis slider 30 is slidably attached to a pair of left and right guide rails 32, 32 extending in the front-rear direction. The guide rails 32 and 32 are fixed to the inside of the mounting machine 11. A pair of upper and lower guide rails 28, 28 extending in the left-right direction are provided on the front surface of the Y-axis slider 30, and the X-axis slider 26 is slidably attached to the guide rails 28, 28 in the left-right direction. The mounting head 24 moves in the left-right direction as the X-axis slider 26 moves in the left-right direction, and moves in the front-rear direction as the Y-axis slider 30 moves in the front-rear direction. The sliders 26 and 30 are driven by drive motors (not shown).

The mounting head 24 includes an auto tool 42 having a plurality of nozzles 40 (here, 12) for sucking parts. The auto tool 42 has a mechanism for revolving the nozzle 40 by rotating the axis of the cylindrical body and a mechanism for rotating the nozzle 40 itself. The nozzle 40 is moved up and down in the Z-axis direction (vertical direction) by a holder raising and lowering device using the Z-axis motor 45 as a drive source. The nozzle 40 uses pressure to adsorb parts to the tip of the nozzle and release the parts adsorbed to the tip of the nozzle. The auto tool 42 can be replaced with a type having a different number of nozzles.

The reel unit 56 includes a plurality of reels 57 around which tapes containing parts are wound, and is detachably attached to the front side of the mounting machine 11. This tape is unwound from the reel 57 and sent out by the feeder unit 58 to the collection position collected by the mounting head 24. The parts camera 54 is arranged in front of the support plate 20 on the front side of the transport portion 18. The imaging range of the parts camera 54 is above the parts camera 54. When the nozzle 40 sucking the parts passes above the parts camera 54, the parts camera 54 captures the state of the parts sucked by the nozzle 40 and outputs the image to the control device 60.

As shown in FIG. 3, the control device 60 is configured as a microprocessor centered on a CPU 61, and has a ROM 62 for storing a processing program, an HDD 63 for storing various data, a RAM 64 used as a work area, an external device and electricity. An input / output interface 65 for exchanging signals is provided, and these are connected via a bus 66. The control device 60 is connected to the transport unit 18, the sampling unit 21, the parts camera 54, the reel unit 56, and the like so as to be capable of bidirectional communication. The sliders 26 and 30 are equipped with position sensors (not shown), and the control device 60 controls the drive motors of the sliders 26 and 30 while inputting the position information from the position sensors.

As shown in FIG. 3, the management computer 80 includes a microprocessor centered on a CPU 81, a ROM 82 for storing a processing program, an HDD 83 for storing various information, a RAM 84 used as a work area, and a control device 60 for each mounting machine 11. The input / output interface 85 for bidirectional communication with the computer is provided, and these are connected via the bus 86. Further, the management computer 80 can input signals from an input device 87 represented by a mouse or a keyboard via the input / output interface 85, and is connected to the display 88 so that various images can be output. The management computer 80 is a computer that manages the production job of the board S, and stores the production job created by the worker. In the production job, the sequence of mounting which component from the feeder at which slot position to the board S of which board type is defined for each mounting machine 11A to 11D, and the board S mounted in this way is defined. The number of sheets to be produced is also specified.

Next, the operation of the production line 10 of the present embodiment configured in this way will be described. The four mounting machines 11A to 11D constituting the production line 10 execute component mounting based on the production job received from the management computer 80. Specifically, as shown in FIG. 1, four mounting machines 11A to 11D constituting the production line 10 sequentially mount parts on one board S, whereby one of the boards is mounted. All the parts to be mounted on the board S are mounted. That is, all the components are mounted on the substrate S between the time when one substrate S is introduced from the left entrance of the production line 10 to the inside and the time when one substrate S is discharged from the right exit to the outside. The number of such boards S specified in the production job is produced.

Next, the operation in which the control device 60 of the mounting machine 11 attracts the parts supplied by the reel unit 56 to the nozzle 40 and mounts them at a predetermined position on the substrate S will be described. First, the CPU 61 of the control device 60 sucks the component to the nozzle 40 of the auto tool 42 according to its own sequence. The CPU 61 sequentially adsorbs the parts having the first to twelfth mounting orders to the nozzle 40 while intermittently rotating the auto tool 42. After that, the CPU 61 controls the X-axis and Y-axis sliders 26 and 30 of the sampling unit 21 to move the mounting head 24 above the parts camera 54, and then the parts camera 54 captures the parts sucked by the nozzle 40. Let me. The CPU 61 makes the auto tool 42 image the parts adsorbed by all the nozzles 40 while rotating the auto tool 42 intermittently. The CPU 61 grasps the posture of the component by analyzing the captured image. Next, the CPU 61 controls the X-axis and Y-axis sliders 26 and 30 of the sampling unit 21 to move the mounting head 24 onto the substrate S, and mounts the components attracted to the nozzle 40 on the substrate S. The CPU 61 sequentially mounts the components having the first to twelfth mounting orders at the mounting positions on the board S while intermittently rotating the auto tool 42. The CPU 61 repeatedly executes this work until the components to be mounted are mounted on the substrate S according to its own sequence, and after the operation is completed, the CPU 61 sends the substrate S to the mounting machine 11 on the downstream side.

Next, the work in which the worker operates the management computer 80 to create a production job will be described. FIG. 4 is a flowchart of the job creation routine. When the operator clicks the job creation start button (not shown) displayed on the display 88, the CPU 81 of the management computer 80 displays an input screen for identification information (ID and password) for performing personal authentication. When authentication can be performed based on the worker identification information input to the input screen, the job creation program installed in the HDD 83 is read and executed.

First, the CPU 81 determines whether to create a new job or restart job creation (S110). Specifically, the CPU 81 makes this determination based on whether the new button or the resume button (neither button is shown) displayed on the display 88 is clicked by the operator. If a new job is created in S110, the CPU 81 displays a step list in which the job creation is divided into a plurality of steps on the display 88, and visualizes the first step in the step list as a processing step (here, the step is being processed). Inverted) and displayed (S120). At the same time, the CPU 81 displays the processing screen of the first step on the display 88 (S130).

Specifically, the CPU 81 displays the operation screen 90 shown in FIG. 5 on the display 88. The operation screen 90 has a first frame 91 that displays a list of steps for creating a job, a second frame 92 that displays an image related to job creation (for example, a CAD image), and a third that displays a table for inputting various data. It is composed of a frame 93. The steps displayed in the step list of the first frame 91 are processed in chronological order from top to bottom. The screens displayed in the second frame 92 and the third frame 93 correspond to the processing screens. Further, at the lower part of the operation screen 90, a "Next" button 94 and a "Save" button 95 are displayed.

Here, as shown in FIG. 5, job creation is divided into (1) board creation step, (2) panel creation step, (3) production condition creation step, and (4) completion confirmation step. There is. The board creation step (1) is divided into three substeps, that is, CAD reading, BOM reading, and part data creation. In CAD reading, a CAD showing information about which component is mounted on the board is read. In BOM reading, BOM (Bill of Materials), which is a list of parts to be used, is read. In the part data creation, the data of the parts lacking data in the list of BOM parts is created. The panel creation step (2) is divided into six substeps, that is, PCB information setting, Gerber reading, board deployment, model / BOM combination, mounting position confirmation, and sequence adjustment. In the PCB information setting, information such as the size of the board is set. PCB is an abbreviation for Print Circuit Board. In Gerber reading, the image of the board is read. Gerber is a format used when importing data into a CAD tool for the purpose of PCB editing. Board deployment defines where and which board to deploy when deploying multiple smaller size boards on a larger size board. In the model / BOM combination, the combination of the model such as CAD data and the BOM used for the model is determined. In the mounting position confirmation, it is confirmed whether or not the defined mounting position has been redesigned due to a version upgrade or the like. In sequence adjustment, the sequence is adjusted according to the design change. The production condition creation step (3) is divided into three substeps, that is, production line setting, option selection, and optimization. In the production line setting, which production line is used for production is set. In the option selection, what kind of option (for example, production method, optimization method) is selected on the current production line is set. Optimization is the task of making improvements to a sequence that seems appropriate, based on the results of actual production. In the end confirmation step of (4), it is decided whether to save or discard the data of the created job. A check box is displayed on the left side of each small step. When the processing of the small step is completed, the check box to the left of the small step is checked. As shown in FIG. 5, the first step, that is, the CAD creation is highlighted or visualized as a processing step in the first frame 91 of the operation screen 90 displayed on the display 88 in S120.

Next, the CPU 81 executes the processing of the currently visualized step in response to the input of the operator (S140). Then, the CPU 81 determines whether or not the "Next" button 94 in the operation screen 90 is clicked by the operator (S150), and if the "Next" button 94 is not clicked, the "Save" button 95 It is determined whether or not is clicked (S160), and if the "save" button 95 is not clicked, the process returns to S140 again. On the other hand, if the "Next" button 94 is clicked in S150, the CPU 81 determines whether or not the process is completed up to the final step, that is, the end confirmation step (S170). If the processing is not completed up to the final step, the CPU 81 saves the completed step in the HDD 83 as a processed step of the job currently being created in association with the worker's identification information (S180). Further, the CPU 81 also stores the processing content of the processed step in the HDD 83 in association with the identification information of the worker (S185). After that, the CPU 81 visualizes and displays the next step of the processed step as a processing step in the first frame 91, and displays the processing screen in the second and third frames 92 and 93 (S190) in S140. move on. In S190, the CPU 81 checks the check box of the step above the step being processed in the first frame 91. FIG. 6 shows the display status of the first frame 91 when the worker completes the process of setting the production line and clicks the “Next” button 94. Here, the option selection is highlighted as a step in progress, and the checkboxes for the steps above it are checked. On the other hand, if the processing has been completed up to the final step in S170, the CPU 81 displays an end screen (not shown) indicating that all the steps of job creation have been completed on the display 88, and at the end confirmation step. The job is saved or destroyed based on the worker's instruction (S200), and this routine is terminated. When the job is saved, the job is saved in the HDD 83 as a job for which all processing has been completed in association with the identification information of the worker.

On the other hand, if the "Save" button is clicked in S160, the CPU 81 considers that the worker has requested the interruption of job creation, and the worker considers the completed step as the processed step of the job currently being created. It is stored in the HDD 83 in association with the identification information of (S210). Further, the CPU 81 also saves the processing content of the processed step in the HDD 83 in association with the identification information of the worker (S220), and ends this routine.

If the job creation is restarted in S110, the CPU 81 reads out the job stored in the HDD 83 in association with the worker's identification information, and determines whether or not the job is a job for which all processing has been completed. (S230). If the job is not a job for which all processing has been completed, the CPU 81 displays a step list in the first frame 91, and processes the processed steps stored corresponding to the identification information of the worker from the HDD 83. The next step of the read and processed step is visualized and displayed in the first frame 91 (S240). At this time, the CPU 81 displays the visualized step processing screen in the second and third frames. Further, the CPU 81 checks the check box of the step above the visualized step in the first frame 91. Then, the CPU 81 proceeds to S140 after S240. FIG. 7 shows the display status of the first frame 91 when the worker completes the option selection process, clicks the “save” button 95, and then resumes job creation. Here, the optimization is highlighted as a step in progress, and the checkboxes for the steps above it are checked.

On the other hand, if the job in S230 is a job for which all processing has been completed, the CPU 81 visualizes the step stored in the HDD 83 as a step having a high processing frequency from the step list in the first frame 91 and processes the step. The screen is displayed in the second and third frames (S250), and the process proceeds to S140. At this time, the CPU 81 checks and displays the check boxes of all the steps of the first frame 91. FIG. 8 shows a display status of the first frame 91 when an operator restarts a job for which all processing has been completed when optimization is stored in the HDD 83 as a step with a high processing frequency.

Here, the correspondence between the constituent elements of the present embodiment and the constituent elements of the present invention will be clarified. The job creation routine carried out by the management computer 80 of the present embodiment corresponds to the work processing support method of the present invention. Further, the management computer 80 of the present embodiment corresponds to the computer of the present invention, the display 88 corresponds to the display means, and the HDD 83 corresponds to the storage means.

According to the present embodiment described in detail above, the job creation is divided into a plurality of steps and displayed, and the step currently being processed by the operator is visualized and displayed as a step being processed. Therefore, the worker can easily visually understand which step of the job creation including the plurality of steps is currently being processed. Also, when the worker resumes the interrupted work, the next step of the processed step is visualized and automatically displayed. Therefore, it is not necessary for the operator to confirm and determine which step to restart from by checking his / her own memory and setting contents, and the interrupted work can be restarted efficiently.

In addition, when a worker restarts a job in which all steps have been completed, the steps that have already been completed are often improved so that better results can be obtained. The steps in which such improvements are made are frequent. Here, when the worker restarts the job for which all the steps have been completed, a predetermined step having a high work frequency is displayed, so that the worker can efficiently execute the improvement work.

Further, by performing personal authentication using the worker's identification information, even if a plurality of workers having different work progresses use the same management computer 80, an appropriate step is processed for each worker. Displayed as a middle step. Therefore, no matter which of the plurality of workers resumes the work, the interrupted job creation work can be efficiently resumed.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be carried out in various embodiments as long as it belongs to the technical scope of the present invention.

For example, in the above-described embodiment, the job creation for performing the work of mounting the component on the board has been described, but the work is not particularly limited to this work. For example, the present invention may be applied to production analysis for improving the work of mounting components on a substrate. As shown in FIG. 9, the production analysis is listed in the first frame 91 by dividing into four steps of selection of improvement target line, selection of improvement target process in line, improvement work, and confirmation of improvement effect. The improvement target line selection is a step of displaying the status of the entire factory and identifying the line that needs improvement from the viewpoint of operation or component error. In-line improvement target process selection is a step of specifying processes, feeders, parts, nozzles, etc. that need improvement from the viewpoint of operation or component error from the processes in the line. Improvement work is a step of navigating and executing countermeasures. Confirmation of the improvement effect is a step of confirming the effectiveness of the countermeasure from the transition before and after the countermeasure for the executed countermeasure content. When the present invention is applied to production analysis, the same effect as that of the above-described embodiment can be obtained. In addition, the present invention may be applied to the creation of data related to mounting a component on a board, the component replenishment work when mounting a component on a board, and the like. Since all of the works are often completed while being interrupted and then restarted, it is highly significant to apply the present invention.

In the above-described embodiment, optimization is exemplified as a step with a high frequency of action, but when there are a plurality of steps with a high frequency of work (for example, both sequence adjustment and optimization), the plurality of steps are visualized. It may be displayed and one of them may be clicked and selected by the operator.

In the above-described embodiment, the CPU 81 determines the step having the highest processing frequency among the plurality of steps based on the actual processing frequency of the worker having the identification information, and corresponds to the identification information with the step as a predetermined step. It may be additionally stored in the HDD 83. In that case, if the determination is affirmative in S230, the CPU 81 reads a predetermined step associated with the identification information from the HDD 83, visualizes it in the first frame 91, and displays it. When a plurality of workers use the same management computer 80, the steps with high processing frequency, that is, the steps for performing improvement work may be different for each worker. Here, when a worker restarts a job for which processing of all steps has been completed, a predetermined step with a high processing frequency associated with the worker is displayed, so that any of a plurality of workers can handle the job. Even if the above is restarted, the improvement work can be executed efficiently.

In the above-described embodiment, the management computer 80 executes the job creation routine, but the control device 60 of the mounting machine 11 may also execute the job creation routine.

In the above-described embodiment, personal authentication is performed using the worker's identification information, and the processed step or the like is stored in association with the worker's identification information, but the present invention is not particularly limited to this. For example, instead of the worker identification information, the identification information of a group to which a plurality of workers belong may be used. In that case, the workers belonging to the group can share the same job and create it.

The present invention can be used, for example, when creating a job for mounting a component on a board.
