Description

[Technical field]

[0001] The present invention relates to a quality improvement support device and a quality improvement support system that support improvement of product quality in a manufacturing facility that manufactures printed circuit boards and the like. [Background technology]

[0002] Conventionally, in a quality improvement support device that supports the improvement of product quality in a manufacturing device that manufactures printed circuit boards, etc., a device that instructs work in various ways to deal with an abnormality that occurs in the manufacturing device has been proposed. For example, Patent Document 1 describes a device in which the authority level of a worker who may perform a work to deal with an abnormality is set according to the content of the work, and the device instructs the work according to the level of the worker. In addition, Patent Document 2 describes a device that escalates the notification target and work content by expanding the target of notification of the work instruction to a higher-ranking person or changing the instructed work content to a more advanced one when the work instruction given to the worker is not performed.

[0003] However, in these quality improvement support devices, feedback from workers regarding work instructions is not sufficiently reflected in more appropriate work instructions provided by the manager.

[0004] For this reason, the manager's cycle, which includes work instructions, and the on-site worker's cycle, which also includes work instructions, did not function adaptively as cycles for improving quality. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] WO2018 / 020556 [Patent Document 2] WO2018 / 020594 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide technology that can provide support so that the manager's cycle and the worker's cycle function adaptively toward improving the quality of products in a manufacturing facility, triggered by work instructions. [Means for solving the problem]

[0007] To solve the above problems, the present invention provides: A quality improvement support device that supports improvement of the quality of a product manufactured by a manufacturing facility, Identification information for identifying a manufacturing member or part included in the manufacturing equipment that is a target for improving the quality of the product; work instruction status information indicating a status of a work instruction for instructing work on the manufacturing equipment in relation to the improvement target; a display unit that displays, for each of the work instructions, production status information associated with a status evaluation index that is an index for evaluating a status of the manufacturing equipment related to the quality of the product; an additional work instruction receiving unit that receives an additional work instruction for instructing the manufacturing equipment to perform additional work; The present invention is characterized by comprising:

[0008] The quality control support device of the present invention is a device for supporting quality control of a manufacturing facility, and includes: specific information for identifying an improvement target, which is a manufacturing member or part included in the manufacturing facility and is a target for improving the quality of the product; and work instruction status information indicating the status of a work instruction for instructing work on the manufacturing facility in relation to the improvement target. The quality control support device of the present invention further includes an additional work instruction receiving unit that receives an additional work instruction for instructing additional work for the manufacturing equipment. That is, the quality control device of the present invention can grasp the status of a work instruction made in relation to an improvement target for improving the quality of a product and the status of the manufacturing equipment related to the quality of the product, and instructs additional work for improving the quality of the product, as necessary. In this way, on the side of the manager who manages the manufacturing equipment to improve the quality of the product, a cycle for quality improvement including a work instruction can be constructed, from a work instruction made for improving the quality of the product, through grasping the status of the work instruction, to an additional work instruction. On the side of the worker who receives a work instruction made for a manufacturing equipment made in relation to a specific improvement target for improving the quality of the product, a cycle for quality improvement including a work instruction can be constructed in the form of receiving an additional work instruction according to the status of the received work instruction. In other words, according to the quality improvement support device of the present invention, it is possible to provide support so that the manager's cycle and the worker's cycle function adaptively toward improving the quality of products in the manufacturing facility, triggered by work instructions. Here, the manufacturing component to be improved may include a program executed in a device included in the manufacturing facility. Furthermore, the person performing the work on the manufacturing facility may be a human worker, may be a device included in the manufacturing facility, or may be a program management device that manages the program executed in the manufacturing facility. In addition, the additional work acceptance unit is not limited to being provided separately from the display unit, and may be displayed on the display unit. Furthermore, the additional work acceptance unit may be displayed on a screen of the display unit that displays the production status information, or may be displayed on another screen transitioned from the screen that displays the production status information.

[0009] In addition, in the present invention, The work instruction status information may include whether or not the work instructed by the work instruction has been performed.

[0010] Even if a work instruction is given in relation to an improvement target, there are cases in which the work is not carried out for various reasons. However, whether or not the instructed work has been carried out is useful information for determining the content and necessity of additional work instructions. By displaying such information as work instruction status information, it is possible to support the manager's cycle and the worker's cycle in functioning more adaptively toward improving the quality of products in the manufacturing equipment, triggered by the work instruction.

[0011] In addition, in the present invention, The manufacturing status information may include time-series status information that represents the status evaluation index and work instruction status information in a time series within a predetermined period of time.

[0012] By displaying such time-series status information, the impact of the status of the work instructions on the status of the manufacturing equipment regarding product quality can be grasped, and the content and necessity of additional work instructions can be more accurately determined. In other words, support can be provided so that the manager's cycle and the worker's cycle function more adaptively toward improving the quality of products in the manufacturing equipment, triggered by the work instructions.

[0013] In addition, in the present invention, The display unit may display history information of the work instructions given in the past in relation to the improvement target identified by the identification information included in the production status information.

[0014] By displaying such work instruction history information, the display unit displays the work status information. Since it is possible to grasp not only the work instruction that was displayed, but also information on past work instructions related to the improvement target, it is possible to more accurately determine the content and necessity of additional work instructions based on the process leading up to the work instruction. In other words, it is possible to provide support so that the manager's cycle and the worker's cycle function more adaptively toward improving the quality of products in the manufacturing facility, using the work instruction as a trigger.

[0015] In addition, in the present invention, The display device may further include a history information designation unit that accepts designation of any one of the multiple pieces of production status information displayed on the display unit, and displays on the display unit the history information related to an improvement target identified by the specific information included in the designated production status information.

[0016] According to this, the history information designation unit can display history information as needed based on the work instruction status information and the situation evaluation index contained in the production status information displayed on the display unit, thereby making effective use of the display space on the display unit.

[0017] In addition, in the present invention, The additional work instruction receiving unit may receive a work instruction that is the same as the work instruction that was previously performed and is included in the history information.

[0018] This allows a user to easily instruct a task that has been instructed in the past and is included in the history information.

[0019] In addition, in the present invention, The additional work instruction receiving unit may be configured to receive a work instruction that is different from the work instruction that was previously performed and is included in the history information.

[0020] This makes it possible to instruct work that has not been instructed before, based on the instructed state information and the situation evaluation index.

[0021] The present invention also provides a method for producing a semiconductor device comprising the steps of: The quality improvement support device; A work instruction receiving device for receiving the work instruction including the additional work instruction, a work instruction status information acquisition unit that acquires the work instruction status information related to the work instruction; a work instruction status information transmitting unit that transmits the acquired work instruction status information; A work instruction receiving device comprising: Including, This quality improvement support system is characterized in that the work instruction status information displayed on the display unit of the quality improvement support device is updated based on the work instruction status information acquired by the work instruction status information acquisition unit.

[0022] According to the quality improvement support system of the present invention, the work instruction status information displayed on the quality improvement support device is updated based on the work instruction status information acquired by the work instruction receiving device, so that a cycle for quality improvement including work instructions is established using the work instruction receiving device on the part of a worker who receives work instructions for manufacturing equipment in relation to a specific improvement target for improving product quality.

[0023] In addition, in the present invention, The work instruction receiving device includes: An instruction content display unit that displays the content of the received work instruction is further provided, The work instruction status information acquisition unit may be configured to accept an input of the work instruction status information by a user of the work instruction receiving device.

[0024] According to this, when a human worker performs instructed work on manufacturing equipment in relation to the improvement target, the worker can understand the content of the work instruction by the instruction content display unit and input the work instruction status information by using the work instruction status information acquisition unit of the work instruction receiving device. Therefore, according to the quality improvement support system of the present invention, a cycle for quality improvement including work instructions can be constructed by the human worker using the work instruction receiving device. The user who inputs the work instruction status information may be the worker who performs the instructed work, or may not be the worker. Effect of the Invention

[0025] According to the present invention, it is possible to realize support in which the manager's cycle and the worker's cycle function adaptively toward improving the quality of products in a manufacturing facility, triggered by work instructions. [Brief description of the drawings]

[0027] [Application example] Hereinafter, application examples of the present invention will be described with reference to the drawings. FIG. 13 shows a management system 1 to which the present invention is applied. The management system 1 includes a management device 100, and a manager terminal 10 and a worker terminal 20 communicatively connected to the management device 100 via a network. The manufacturing equipment in a surface mounting line for printed circuit boards includes a mounter X2, a post-mount inspection machine Y2, and post-reflow inspection machines Y3 and Y4 communicatively connected to the management device 100 via the network. As shown in FIG. 1, the manufacturing equipment includes a printer X1, a reflow oven X3, and a post-print inspection machine Y1. As will be described later, the management device 100 can also be operated by connecting to these devices via a network, but here, the management device 100 in the configuration shown in FIG. 13 will be described. The manager terminal 10 is a quality control device according to the present invention. 13, the quality improvement support system of the present invention includes at least the manager terminal 10 and the worker terminal 20. The quality improvement support system of the present invention can also be applied to the management system 1, but in the example shown in FIG.

[0028] The mounting information and inspection result collection unit 111 of the management device 100 collects mounting information from the mounter X2 and inspection results from the post-mount inspection machine Y2 and the post-reflow inspection machines Y3 and Y4, and records them in a production information database (DB) 112. Here, the mounting information and inspection results correspond to the equipment status information of the present invention.

[0029] The abnormality detection unit 113 detects an abnormality in any of the components on the printed circuit board based on the information recorded in the production information database 112. Then, the cause analysis unit 114 analyzes the cause of the abnormality detected by the abnormality detection unit 113.

[0030] The work instruction generation unit 115 generates a work instruction for eliminating the abnormality based on the work instruction rules 121 according to the cause of the abnormality identified by the analysis by the cause analysis unit 114. Work instructions related to the mounter X2 include, for example, maintenance and replacement of the nozzle, but are not limited to these.

[0031] The work instruction generated by the work instruction generation unit 115 is recorded in the management database 116 together with the location and condition of the abnormality. In addition, the work instruction generated by the work instruction generation unit 115 is transmitted to the worker terminal 20 via the work instruction transmission unit 117.

[0032] In the worker terminal 20, work information relating to the status of response to the transmitted work instruction information is input. The instructed work transmitted to the worker terminal 20 is not necessarily performed, and may not be performed. For this reason, when the instructed work is performed, the fact that the work has been performed is input to the worker terminal 20. When the fact that the work has been performed is not input to the worker terminal 20, the work has not been performed. In other words, as work information, implementation status information indicating whether the instructed work has been performed or not is transmitted from the worker terminal 20 to the work information receiving unit 122 of the management device 100. Here, the work information corresponds to the work status information of the present invention.

[0033] The work information received by the work information receiving unit 122 is recorded in the management database 116 by the work information recording unit 123 in association with the location of the abnormality corresponding to the work content.

[0034] The line status data generation unit 118 generates line status data based on the work instructions generated in the work instruction generation unit 115 and the information recorded in the management database 116. The line status data is specifically data that constitutes a line status data display screen 70 (see FIG. 8) and a work instruction issuance screen 80 (see FIG. 11) that are displayed on the line status data display unit 12 of the manager terminal 10. The data that constitutes the line status data display screen 70 includes the number of warnings (including the number of completed tasks) 701, the last update date and time 702, a monitoring period 703, and a warning list 705. The warning list 705 includes a plurality of individual warning-related information 705a to 705f, and each of the individual warning-related information 705a, etc. includes a work instruction status 706, information for identifying the location of the abnormality (Device Type 707, Device ID 708, Line 709, etc.), an actual defect image 710, the number of errors 711 (the number of actual defects 712, Recognition Errors 713, and Adsorption Errors 714), the number of detected production fluctuations 715 (the number of defects signs 716), the last detection time 717, and within-monitoring period / production fluctuation detection status 718. The data constituting the work instruction issuance screen 80 includes work instructions for the device that is the subject of the warning, including the date and time 811 for each work instruction, the contents of the work instruction event 812, the status of the work instruction 813, the specific work instruction wording 814, and a re-notification button 816 for instructing re-notification. The line data display unit 12 corresponds to the display unit of the present invention. The work instruction status 706 corresponds to the work instruction state information of the present invention. Information for identifying the location of an abnormality, such as the Device Type 707, corresponds to the identification information of the present invention. The actual defect image 710, the number of errors 711 (the number of actual defects 712, Recognition Errors 713, and Pickup Errors 714), the number of production fluctuation detections 716 (the number of defects signs 716), and the production fluctuation detection status within the monitoring period 718 correspond to the status evaluation index of the present invention. The individual warning related information 705a to 705f and the warning list 705 including these correspond to the manufacturing status information of the present invention. The work instruction event history 810, which is the history information of the work instruction event for the past seven days, corresponds to the history information of the present invention.

[0035] Of these, icons 719 displayed in the work instruction status 706 item indicate various states of the work instruction, such as icon 719a indicating "work instruction notified (currently displayed)" and icon 719b indicating "improvement work completed," as shown in Fig. 9. When a details screen display button 720 displayed in the first row of the status 706 item in which these icons 719a are displayed is selected, the work instruction issuance screen 80 shown in Fig. 11 is displayed. Here, the details screen display button 720 corresponds to the history information designation section of the present invention.

[0036] This work instruction issuance screen 80 displays a work instruction event history 810, which is a history of past work instructions related to the nozzle that is the target of the selected work instruction in the first row. This work instruction event history 810 consists of items of date and time 811, event content 812, status 813, work instruction 814, and re-notification 815. For example, it can be recognized from the information displayed in the items of date and time 811, event content 812, status 813, and work instruction 814 that a large number of actual defects were detected at 8:10 on September 1, 2020, a work instruction to "replace the relevant nozzle" was notified, and is currently being displayed. And, a re-notification button 816 is displayed in the item of re-notification 815. When this re-notification button 816 is selected, a work instruction with the same content as the work instruction event displayed in the fourth row of the work instruction event history 810 can be re-notified. Here, the re-notification button 816 corresponds to the additional work instruction receiving unit of the present invention.

[0037] Furthermore, the work instruction issuing screen 80 displays a new work instruction issuing area 820 in which the administrator can input the content of a new work instruction to be issued in text. Also displayed are a work instruction text change button 830, which is selected when changing the text entered in the new work instruction issuing area 820, and a work instruction issuing button 840, which is selected when issuing the work instruction entered in the new work instruction issuing area 820. When the administrator wants to change a previously issued work instruction such as "Please perform device maintenance on the nozzle in question" to a different text and create a new work instruction, the administrator issues a new work instruction using the new work instruction issuing area 820. In such a case, the administrator selects the work instruction text change button 830 and inputs the new work instruction text in the new work instruction issuing area 820. Here, the administrator inputs the new work instruction text "Please disable the nozzle in question" in the new work instruction issuing area 820. The content of the new work instruction can be confirmed by a work instruction image area 850, which displays an image of the screen display on the worker terminal 20 including the work instruction to be issued. Then, the manager can issue a new work instruction by selecting the work instruction issue button 840. Here, the new work instruction issue area 820, the work instruction wording change button 830, and the work instruction issue button 840 correspond to the additional work instruction receiving section of the present invention that receives a work instruction different from a work instruction issued in the past.

[0038] Fig. 14 is a schematic diagram showing the features of the present invention that are applied to the above-mentioned management system 1. The cycle connected by the solid arrows on the upper side of Fig. 14 shows an outline of the cycle on the manager's side in the quality improvement process of the product manufactured by the manufacturing equipment, and the cycle connected by the dashed arrows on the lower side of Fig. 14 shows an outline of the cycle on the worker's side in the same quality improvement process. Here, the worker corresponds to any one of a person, the mounting machines X1 to X3, the inspection machines Y1 to Y4, and the program management server 40, depending on the work content. As shown in FIG. 14, the present invention supports the realization of the function of running a quality improvement cycle while improving the quality improvement cycle itself by fusing the manager's cycle Sab1-Sa2-Sa3-Sab1 with the worker's cycle Sb0-Sab1-Sb2-Sb3 (Sb0)-Sab1 via a central work instruction Sab1.

[0039] That is, an abnormality is detected in the manufacturing equipment (Sb0), its cause is analyzed, and work instructions are given to the workers based on the analysis results (Sab1). Then, the workers perform the instructed work (including not performing it) (Sb2) and record the work implementation status (Sb3). Meanwhile, the manager checks the implementation status of the instructed work (Sa2) and accordingly reissues the previously issued work instruction (including changing the work instruction rule) (Sa3), thereby returning to the work instruction (Sab1). On the worker's side, further work instructions are given based on the work record (Sb3) (Sab1). Here, the manager who gives the work instructions may be a person or may be a device including the above-mentioned management device 100.

[0040] In this way, the work instruction (Sab1) serves as a trigger for the cycle on the manager's side, the cycle on the worker's side (Sab1-Sa2-Sa3-Sab1), and the cycle on the worker's side (Sb0-Sab1-Sb2-Sb3 (Sb0)-Sab1) to merge and function adaptively, and the quality improvement cycle starting from the abnormality detection (Sb0) rotates from the work instruction (Sab1) to the next work instruction (Sab1) while improving the quality improvement cycle itself. In other words, the cycle on the manager's side and the cycle on the worker's side function adaptively means that it is possible to immediately respond to an abnormality in the manufacturing equipment, and further to recover when the response is not successful. This allows the man-hours of high-cost personnel such as managers to be reduced, thereby reducing costs or allowing more quality maintenance and improvement activities to be performed. In addition, by enabling an immediate response to an abnormality, it is possible to realize improvement in quality and productivity and reduction in losses. The quality improvement support device and the quality improvement support system according to the present invention provide such a technology.

[0041] Example 1 Hereinafter, a management system 1 including a quality improvement support device system according to a first embodiment of the present invention will be described in more detail with reference to the drawings. (System Configuration) 1 is a schematic diagram showing an example of the configuration of manufacturing equipment in a surface mounting line for printed circuit boards according to this embodiment. Surface mounting technology (SMT) is a technology for soldering electronic components to the surface of a printed circuit board, and the surface mounting line mainly consists of three processes: solder printing, component mounting, and reflow (solder deposition).

[0042] As shown in FIG. 1, the surface mounting line is provided with, in order from the upstream side, a solder printing device X1, a mounter X2, and a reflow furnace X3 as manufacturing equipment. The solder printing device X1 is a device that prints solder paste on electrode portions (called lands) on a printed circuit board by screen printing. The mounter X2 is a device that picks up electronic components to be mounted on the board and places the components on the solder paste at the corresponding locations, and is also called a chip mounter. The reflow furnace X3 is a heating device that heats and melts the solder paste, cools it, and solders the electronic components onto the board. When the number and types of electronic components to be mounted on the board are large, multiple mounters X2 may be provided on the surface mounting line.

[0043] In addition, the surface mounting line has a number of processes, from solder printing to component mounting to reflow, at the end of each process. A system is installed that inspects the condition of the boards and automatically detects defects or potential defects. In addition to automatically separating good and bad products, the system also has the function of feeding back the results of inspection and analysis to the operation of each manufacturing device (for example, changing the mounting program).

[0044] The solder print inspection device Y1 is a device for inspecting the printing condition of the solder paste on the board discharged from the solder printing device X1. The solder print inspection device Y1 measures the solder paste printed on the board in two or three dimensions, and judges whether or not various inspection items are normal (within the allowable range) based on the measurement results. Inspection items include, for example, the volume, area, height, positional deviation, and shape of the solder. An image sensor (camera) can be used for two-dimensional measurement of the solder paste, and a laser displacement meter, phase shift method, spatial coding method, light section method, etc. can be used for three-dimensional measurement.

[0045] The component inspection device Y2 is a device for inspecting the placement of electronic components on the board carried out from the mounter X2. The component inspection device Y2 measures the components (which may be parts of the components such as the component body or electrodes) placed on the solder paste in two or three dimensions, and judges whether or not various inspection items are within normal values ​​(tolerance ranges) based on the measurement results. Inspection items include, for example, component position deviation, angle (rotation) deviation, missing parts (no components placed), wrong components (different components placed), wrong polarity (different polarity of electrodes on the component side and the board side), inversion (components placed upside down), and component height. As with solder printing inspection, an image sensor (camera) can be used for two-dimensional measurement of electronic components, and a laser displacement meter, phase shift method, spatial coding method, light section method, etc. can be used for three-dimensional measurement.

[0046] The visual inspection device Y3 is a device for inspecting the quality of soldering on the boards removed from the reflow furnace X3. The visual inspection device Y3 measures the soldered part after reflow in two or three dimensions, and judges whether various inspection items are normal (within the allowable range) based on the measurement results. Inspection items include the same items as in component inspection, as well as the quality of the solder fillet shape. In addition to the above-mentioned laser displacement meter, phase shift method, spatial coding method, and light section method, the so-called color highlight method (a method in which R, G, and B lighting are applied to the solder surface at different angles of incidence, and the reflected light of each color is photographed with a zenith camera to detect the 3D shape of the solder as 2D hue information) can be used to measure the solder shape.

[0047] The X-ray inspection device Y4 is a device for inspecting the state of soldering on a board using an X-ray image. For example, in the case of packaged components such as BGA (Ball Grid Array) and CSP (Chip Size Package) or multi-layer boards, the solder joints are hidden under the components or boards, so the appearance inspection device Y3 (i.e., appearance images) cannot inspect the state of the solder. The X-ray inspection device Y4 is a device for complementing such weaknesses of appearance inspection. Inspection items of the X-ray inspection device Y4 include, for example, component positional deviation, solder height, solder volume, solder ball diameter, back fillet length, and the quality of solder joints. Note that, as the X-ray image, an X-ray transmission image may be used, and it is also preferable to use a CT (Computed Tomography) image.

[0048] (Management device) The manufacturing equipment X1 to X3 and inspection equipment Y1 to Y4 described above are connected to a management device 100 via a network (LAN). The management device 100 is a system that manages and controls the manufacturing equipment X1 to X3 and inspection equipment Y1 to Y4, and is configured by a general-purpose computer system equipped with a CPU (processor), a main storage device (memory), an auxiliary storage device (hard disk, etc.), input devices (keyboard, mouse, controller, touch panel, etc.), a display device, etc., although not shown. The functions of the management device 100, which will be described later, are implemented by the auxiliary storage device This is achieved by the CPU reading and executing the program stored in the

[0049] The management device 100 may be configured with one computer or multiple computers. Alternatively, all or part of the functions of the management device 100 may be implemented in a computer built into any of the manufacturing devices X1 to X3 or the inspection devices Y1 to Y4. Alternatively, part of the functions of the management device 100 may be realized by a server (such as a cloud server) on a network.

[0050] An administrator terminal 10, an operator terminal 20, and a program management server 40 are connected to the management device 100 via a network (LAN). The program management server 40 is a server that manages an inspection and mounting program 50. The inspection and mounting program 50 is actually a program that controls the manufacturing devices X1 to X3 and the inspection devices Y1 to Y4, and is stored in a predetermined storage area of ​​the program management server 40, while being downloaded to each of the manufacturing devices X1 to X3 and the inspection devices Y1 to Y4 as necessary, stored in a predetermined storage area of ​​each device, and executed by each device.

[0051] The management device 100 of this embodiment has a functional unit for realizing a function for a manager of a manufacturing facility to efficiently perform maintenance and quality control of the facility. FIG. 2 shows a block diagram of the functional unit of the management device 100.

[0052] As shown in FIG. 2, the management device 100 has a mounting information / inspection result collection unit 111, a production information database 112, an abnormality detection unit 113, a cause analysis unit 114, a work instruction generation unit 115, a management database 116, a work instruction transmission unit 117, a line status data generation unit 118, an additional work instruction issuance unit 119, a work instruction rule editing unit 120, work instruction rules 121, a work information receiving unit 122, and a work information recording unit 123.

[0053] The mounting information and inspection result collecting unit 111 collects mounting information including information on components such as boards, solder, and various electronic components used in the manufacturing equipment X1 to X3, and information on various members and mechanisms that constitute these manufacturing equipment X1 to X3, and inspection results by the inspection equipment Y1 to Y4. As the inspection results, information on cases where there is an abnormality is collected. Here, cases where there is an abnormality include not only "actual defects" that are determined to be defective by the inspection equipment Y1 to Y4 and also determined to be defective by visual inspection, but also so-called "overlooking" cases that are determined to be defective by the inspection equipment Y1 to Y4 but are determined to be "good" by visual inspection. The information on the abnormality is linked to mounting information on the equipment components and components where the abnormality occurred. The inspection results also include information on errors detected in each process of the manufacturing equipment X1 to X3. Such error information is also linked to mounting information on the equipment components and components where the error occurred.

[0054] The production information database 112 is a database in which the mounting information and inspection results collected by the mounting information and inspection result collecting unit 111 are recorded in association with each other for the same board, the same component, the same date and time, etc.

[0055] The abnormality detection unit 113 detects an abnormality in any of the components on the printed circuit board based on the information recorded in the production information database 112. Here, the presence or absence of an abnormality is detected based on, for example, the continuous occurrence or occurrence rate of actual defects or the like.

[0056] The cause analysis unit 114 analyzes the cause of the abnormality detected by the abnormality detection unit 113 .

[0057] The work instruction generating unit 115 generates a work instruction for eliminating the abnormality based on the work instruction rule 121 according to the cause of the abnormality identified by the analysis by the cause analyzing unit 114. Such work instructions for the printer X1 include, for example, mask cleaning, solder refilling, changing or correcting the mask position, etc. The contents of the work instructions are not limited to these. The contents of the work instructions related to the mounter will be described later.

[0058] The work instruction generated by the work instruction generating unit 115 is recorded in the management database 116 together with the location and the situation of the abnormality. The work instruction generated by the work instruction generating unit 115 is transmitted to at least one of the worker terminal 20, the mounting machine / inspection machine 30, or the program management server 40 via the work instruction transmitting unit 117 depending on the contents of the work instruction. That is, if the work instruction is an instruction for the worker, it is sent to the worker terminal 20, if it is an instruction for device control, it is sent to the target device included in the mounting machine / inspection machine 30, and if it is an instruction for changing the parameters of the program, it is sent to the program management server 40. Here, the mounting machine / inspection machine 30 is a collective term for the manufacturing devices X1 to X3 and the inspection devices Y1 to Y4, and in reality, the work instruction is transmitted to at least one of these devices. The work instruction may be automatically generated by the work instruction generating unit 115, or may be generated based on an instruction from the administrator.

[0059] Work information for a work instruction sent from the work instruction sending unit 117 to the worker terminal 20, the mounting machine / inspection machine 30 or the program management server 40 is sent from each of the worker terminal 20, the mounting machine / inspection machine 30 or the program management server 40 to the work information receiving unit 122.

[0060] The work instructions transmitted from the work instruction transmission unit 117 to the worker terminal 20, the mounting machine / inspection machine 30, or the program management server 40 are not necessarily carried out. For example, there are cases where a work instruction is sent to the worker terminal 20, but the operator does not have time to view the work instruction. There are also cases where the operator recognizes the work instruction received at the worker terminal 20, but does not have time to carry it out. There are also cases where the production model is changed or replaced due to a changeover, and the target of the work instructed via the worker terminal 20 is no longer available. Regarding the work instructions sent to the mounting machine / inspection machine 30, there are cases where the production model has changed or been replaced due to a change in setup, and the instructed work is no longer applicable. In addition, when a certain device ID is deactivated, there are cases where the production stops because there is no alternative, or the instructed work cannot be performed due to production reasons such as not wanting to stop the production line. In addition, there are cases where the instructed work is rejected by a judgment unit in the mounting machine. Regarding the work instructions sent to the program management server 40, the version of the mounting program or part library to be the subject of the instructed work may not match the contents of the instructions. Also, the mounting program or part library to be the subject of the instructed work may be locked and cannot be changed. Also, the instructed work may be rejected by the judgment section in the program management server.

[0061] The work information received by the work information receiving unit 122 from each of the worker terminal 20, the mounting machine / inspection machine 30, or the program management server 40 is recorded in the management database 116 by the work information recording unit 123 in association with the location of the abnormality corresponding to the work content.

[0062] The line status data generation unit 118 generates line status data based on the work instructions generated by the work instruction generation unit 115 and the information recorded in the management database 116. Specifically, the line status data is data that constitutes the line status data display screen (see FIG. 8) and the work instruction issuance screen (see FIG. 11) that are displayed on the line status data display unit 12 of the manager terminal 10. The details of the content of the line status data will be described later, but the line status data includes, as data that constitutes the line status data display screen, the number of warnings (including the number of warnings The line status data includes information such as the number of work orders that have been performed (including the number of work orders that have been performed) 701, the last update date and time 702, a monitoring period 703, the status of the work order 706, information for identifying the location of the abnormality (device type, device ID, line, etc.), actual defect image, the number of errors (the number of actual defects, recognition errors, and pickup errors), the number of production fluctuations detected (the number of signs of defect), the last detection time, and the production fluctuation detection status within the monitoring period. The line status data also includes, as data constituting the work instruction issuance screen, the date and time of each work instruction for the device that was the subject of a warning, the contents of the work instruction event, the status of the work instruction, the specific work instruction wording, and the history of work instruction event information for the past seven days including a button for instructing re-notification.

[0063] The line status data generated by the line status data generation unit 118 is transmitted to the manager terminal 10 and displayed. When an additional work instruction is selected by the manager terminal 10, the additional work instruction is issued by the additional work instruction issuing unit 119, and the additional work instruction is generated by the work instruction generating unit 115. This additional work instruction includes a work instruction that is the same as the one already notified and a work instruction newly created by the manager. When a change in the work instruction rule is selected by the manager terminal 10, the work instruction rule editing unit 120 edits the work instruction rule 121. The additional work instruction may be issued by the additional work instruction issuing unit 119 in response to an instruction from the manager via the manager terminal 10, or may be issued automatically by the additional work instruction issuing unit 119.

[0084] (Mounter) In the following, the operation of each functional unit of the management device 100, the manager terminal 10, and the worker terminal 20 will be described in detail using the mounter X2 as an example.

[0085] FIG. 5 is a diagram showing a schematic configuration of the mounter X2. The mounter X2 includes a stage 60 on which the board B is placed, a plurality of feeders 61 that supply electronic components P, a movable head 62 that picks up the electronic components P, a plurality of nozzles 63 attached to the head 62, and a vacuum pump 64 that controls the air pressure of each nozzle. Electronic components P with different part numbers are set in each row of the feeders 61. The mounter X2 also includes an upper camera 65, a lower camera 66, a contact sensor 67 that measures the contact pressure of the nozzle end face, and a pressure sensor 68 that measures the air pressure of the nozzle as an observation system for detecting abnormalities in the operation of the mounter X2. The control unit 69 is a block that controls, calculates, and processes information for each part of the mounter X2, and includes a CPU (processor), memory, and the like. It may also include an output device that outputs information. As for the coordinate system, the X-axis and Y-axis are parallel to the board surface, and the Z-axis is perpendicular to the board surface.

[0086] When the board B is carried onto the stage 60, the control unit 69 controls each nozzle 63 according to a mounting program to pick up and transport the necessary electronic components P from the feeders 61 and sequentially place them on the board B. When the placement (mounting) of all the electronic components P is completed, the board B is carried out to the downstream process (inspection device Y2). In addition, as manufacturing information of the board B, manufacturing log information including manufacturing abnormality information associated with the board ID, the part number of each component, the circuit number, and information indicating the equipment member that processed each component (nozzle ID, feeder ID) is recorded in the memory of the mounter X2.

[0087] Figure 6 is an example of manufacturing log information for mounter X2. Each line is a manufacturing record for one component, and includes information such as the board ID, component part number, circuit number, nozzle ID, feeder ID, and manufacturing abnormality information (number of image judgment processing errors, number of component non-pickup errors). By referencing the manufacturing log information, it is possible to know which equipment or component was used to manufacture each component on the board.

[0088] FIG. 7 is a functional block diagram of the management device 100, which clearly shows the configuration related to the mounter X2. The functional blocks common to those in the functional block diagram shown in FIG. 2 are designated by the same reference numerals, and detailed explanations thereof will be omitted. Here, the inspection and mounting program 50m is This shows the programs related to Mounter X2 out of 50 programs.

[0089] The mounting information and inspection result collecting unit 111 collects information on components such as various electronic components, boards, and solders used in the production line, information on various members and mechanisms constituting manufacturing equipment such as the mounter X2, the above-mentioned manufacturing log information (including manufacturing abnormality information) from the mounter X2, and information on the inspection results of the board after mounting (particularly information on actual defects and oversight) from the component inspection equipment Y2. The timing of collecting this information is arbitrary, and the information may be acquired at a predetermined time or frequency, or the information may be acquired in response to an acquisition request from a user. Information on components can be collected, for example, when a new component is introduced into the production line, or when a component of a different manufacturing lot with an existing component number is introduced into the production line. Information on various members and mechanisms can be collected, for example, when equipment components are replaced or maintained, or when new equipment components are introduced into the production line. The control unit 69 of the mounter X2 can transmit manufacturing log information to the management device 100, for example, every time mounting of a board is completed in the mounter X2. The inspection result information can be collected, for example, each time the component inspection device Y2 completes the inspection of a board.

[0090] The abnormality detection unit 113 detects abnormalities such as errors during component manufacturing and defects during inspection from the information collected by the mounting information and inspection result collection unit 111 and recorded in the production information database 112 .

[0091] The cause analysis unit analyzes the cause of an anomaly detected by the anomaly detection unit 113, and extracts device components, part numbers, and program parameters that are presumed to be the cause of the anomaly. The timing and method of the cause analysis are not particularly limited, but the cause analysis can be performed for each predetermined collection period based on, for example, a comparison of the number of times an anomaly has occurred for each device component and part number with a normal value, a comparison of the number of times an anomaly has occurred between different components and part numbers of the same type, etc.

[0092] The work instruction generating unit 115 generates a work instruction based on the cause of the abnormality analyzed by the cause analyzing unit 114 and work instruction rules 121 that are predefined for eliminating the abnormality according to the cause of the abnormality. Examples of work instructions include the following. That is, a work instruction for the mounter X2 is to stop using a particular nozzle or feeder. Furthermore, work instructions for the program management server 40 are, for the mounter X2, a change or correction of mounting coordinates, a change in component dimensions or tolerance, and a change in inspection standards for the post-mount inspection machine Y2. Work instructions to the worker via the worker terminal 20 include replacement or maintenance of nozzles, feeders, and heads, and work that cannot be performed automatically by the mounter X2 or the post-mount inspection machine Y2. The contents of the work instructions are not limited to these.

[0093] The work instructions generated in the work instruction generation unit 115 and the line status data generated based on the information recorded in the management database 116 are transmitted from the line status data generation unit 118 to the manager terminal 10 and displayed on the line status data display unit 12.

[0094] (Administrator screen (line status data display screen)) Fig. 8 shows an example of a line status data display screen 70 displayed on the line status data display unit 12 of the manager terminal 10. In Fig. 8, the leading lines of the symbols are shown with dashed lines to distinguish them from the display on the screen. In the upper left area of ​​the line status data display screen 70, a title "Warning List" indicating the displayed contents, such as "Warning List (6 in total, 2 work completed)", and a title and number 701 including the total number of warnings (6) and the number of warnings for which work has been completed (2) are displayed. With such a display, the number of warnings and the number of warnings for which work has been completed can be easily seen. It can be easily understood. In addition, to the right of the title and number 701, the last update date and time 702 of the data displayed in the "Warning List" is displayed as 9:20:34 on September 1, 2020. In addition, a monitoring period 703, which is a data collection period including the start (17:00 on August 31, 2020) and end (9:00 on September 1, 2020) of the collection period of the data displayed in the "Warning List", is displayed. Here, the Auto Update check box 704a that automatically updates the collection period of the data displayed in the "Warning List" is checked, and the data collection period is set to be automatically updated. The start and end of the data collection period can also be specified by the user. In addition, the user can manually update the data collection period by clicking or touching the Update button 704b. Here, the monitoring period 703, which is a data collection period, corresponds to a predetermined period of the present invention.

[0095] The line status data display screen 70 displays a warning list 705 in table format. In the warning list 705, information on each warning is displayed in one row, such as individual warning related information 705a to 705f. The header row of the table displays the item names of the information in each column constituting the individual warning related information 705a to 705f summarized in one row. Here, each of the individual warning related information 705a to 705f includes information on a status 706, a device type 707, a device ID 708, a line 709, an actual defective image 710, an error count 711, an actual defect 712, a recognition error 713, and a pickup error 714, a defect sign 716 which is a production fluctuation detection count 715, a last detection time 717, and a production fluctuation detection status within a monitoring period 718.

[0096] In the status 706 item of the line status data display screen 70, the status of the work instruction for each warning is displayed by an icon 719 (icons 719a to e indicating the status are collectively referred to as icon 719), and in this column, together with the icon 719 indicating the status, a detailed screen display button 720 for displaying a detailed screen as described below is also displayed. Fig. 9 shows the icon 719, the content and state of the status indicated by the icon 719, and the action that the manager should take in response to the status indicated by such an icon 719.

[0097] 9 indicates "Work instruction notified (currently displayed)," which means that the status of the latest work instruction for the improvement target estimated by the cause analysis is not yet performed. Therefore, when this icon 719a is displayed, the action that the manager should take is to wait for the instructed work to be performed, or to provide guidance to the worker on how to perform the work.

[0098] 9 indicates "Improvement work completed," which means that the status of the latest work instruction for the improvement target is "completed." Therefore, when this icon 719b is displayed, the action that the manager should take is to check the effect of the work that has been performed.

[0099] 9 indicates "no improvement work assignment", which means that the status of the work instruction for the guideline to the improvement target is in a state where no work instruction is assigned. Therefore, the action that the manager should take when this icon 719c is displayed is to consider the content of the work instruction and give the work instruction to the worker.

[0100] The icon 719d in the fourth row of the table shown in Fig. 9 indicates "Excessive notifications on the same day (display ended)", meaning that the status of the latest work instruction for the improvement target is in a state where the number of simultaneous notifications has exceeded. Therefore, the action that the administrator should take when this icon 719d is displayed is to notify the same work instruction again, since the display ended without the instructed work being performed. It is possible that...

[0101] Icon 719e (not shown in FIG. 8 but marked to distinguish it from other icons) in the fifth row of the table shown in Fig. 9 indicates "Waiting to obtain improvement work instructions", meaning that the status of the latest work instructions for the improvement target is in a state of waiting for an acquisition request. Therefore, a possible action that the manager should take when this icon 719e is displayed is to check whether the work instruction application installed on the worker terminal 20 or the like that receives the work instructions is set to receive notifications of work instructions.

[0102] In this way, the manager can check whether or not there is any action that needs to be taken by looking at the icon 719 displayed in the status 706 item of the warning list 705 on the line status data display screen 70, and can decide on the next action if necessary.

[0103] The type of device member or part to be improved is displayed in the Device Type 707 item of the warning list 705 on the line status data display screen 70. For mounter X2, the type names Nozzle, Header, Feeder, and Component Number are displayed. An icon indicating the type may be displayed together with these letters.

[0104] In the item of device ID 708 in the warning list 705 on the line status data display screen 70, the device ID identifying the manufacturing material or part to be improved is displayed, such as "NOZZLE200340."

[0105] In the item of line 709 in the warning list 705 on the line status data display screen 70, the name of the line to be improved is displayed as "Line-1", "Line-2", etc.

[0106] In the item of actual defect image 710 in the warning list 705 on the line status data display screen 70, when an actual defect occurs, an image 721 of the improvement target which is an actual defect captured by the inspection device Y3 is displayed.

[0107] The item of the number of errors 711 in the warning list 705 of the line status data display screen 70 consists of three items, namely, actual defects 712, recognition errors 713, and pick-up errors 714, and the number of errors for each item is displayed as a number. Furthermore, for each error number, a bar graph expressing the relative ratio by the width from the left end of the display area is displayed over the display area of ​​each error number so that the relative ratio for each warning can be visually recognized. In the figure, the number of errors for each item is distinguished by a shading display mode such that the number of actual defects bar graph 722 is filled in black, the number of recognition errors bar graph 723 is hatched upward to the right, and the number of pick-up errors bar graph 724 is hatched upward to the left, but in reality, they can be distinguished by applying different colors. Furthermore, by displaying 0 and numbers other than 0, including the number of production fluctuations detected, which will be described later, in different brightness or colors, the presence or absence of errors can be more clearly recognized.

[0108] The number of defective signs 716 is displayed in the item of the number of production fluctuations detected 715 in the warning list 705 of the line status data display screen 70. The method of detecting a defective sign is not particularly limited, but for example, a defective sign may occur when the average value of the process capability index of a predetermined number of consecutive boards falls below a predetermined threshold, and the number of occurrences may be regarded as the number of defective signs 716. Here, as with the number of errors 711, a defective sign number bar graph 725 expressing the relative ratio by the width from the left end of the display area is superimposed on the display area of ​​the number of defective signs so that the relative ratio of each warning can be visually recognized. This defective sign number bar graph 725 is also displayed with a different shade than the actual defective number bar graph 722, etc., but can be distinguished by applying a different color from the actual defective number bar graph 722, etc. An index other than 6 may be used.

[0109] The last detection time 717 item of the warning list 705 on the line status data display screen 70 displays the last detection time, which is the end of the collection period of the data displayed in the warning list 705, as "2020-09-01 08:10:24".

[0110] In the item of Error / production fluctuation detection status within monitoring time 718 in the warning list 705 on the line status data display screen 70, a graph is displayed showing the change in the number of detected errors / production fluctuations within the monitoring time in time series, with the monitoring period on the horizontal axis and the number of detected errors / production fluctuations on the vertical axis for each warning. In this graph, the graphs corresponding to each item are distinguished by the same display manner as the bar graphs 722, etc. for each item of actual defect 712, recognition error 713, pickup error 714, and defect sign 716. That is, in the graph of error / production fluctuation detection status within monitoring time 718, the bar graph showing the number of actual defects is displayed in black, the graph showing the number of recognition errors is displayed with hatching slanting upward to the right, the graph showing the number of pickup errors is displayed with hatching slanting upward to the left, and the graph showing the number of defect signs is displayed with gray filling. In addition to the graphs showing each of these items, the graph of error / production fluctuation detection status 718 within the monitoring time shows that a work instruction has been notified and that the notified work instruction has been implemented by a band-shaped area 7283 along the horizontal axis (see FIG. 10). That is, the graphs in the first, fourth, and sixth rows of the error / production fluctuation detection status within the monitoring time show a band-shaped area 7283 of lattice hatching, which indicates that a work instruction has been notified, superimposed along the horizontal axis in chronological order. In addition, the graphs in the second and third rows of the error / production fluctuation detection status within the monitoring time show a band-shaped area 7295 of dot hatching, which indicates that the notified work instruction has been implemented, superimposed along the horizontal axis in chronological order. These band-shaped areas 7283 and 7295 can also be displayed in different colors in practice. Here, for each warning displayed in the item of error / production fluctuation detection status within monitoring time 718, the horizontal axis represents the monitoring period and the vertical axis represents the number of detected errors / production fluctuations, and graphs (graphs 728, 729, etc. described later) showing the change in the number of detected errors / production fluctuations within the monitoring time in time series correspond to the time series status information of the present invention.

[0119] (Administrator screen (work instruction issuing screen)) Fig. 11 shows an example of the display of a work instruction issuance screen 80. This work instruction issuance screen 80 is a screen that is displayed when a detailed screen display button 720, which is displayed together with an icon in the status item of the line status data display screen shown in Fig. 8, is selected. Note that in Fig. 11, the leader lines of symbols are shown with dashed lines to distinguish them from the display of the screen.

[0120] At the top of the work instruction issuing screen 80, a work instruction event history 810 for the past seven days is displayed in a table format. At the bottom left of the work instruction issuing screen 80, a new work instruction issuing area 820 is provided where the administrator can input the content of a new work instruction to be issued in text. At the bottom of the new work instruction issuing area 820, a work instruction text change button 830 is displayed, which is selected when changing the text entered in the new work instruction issuing area 820, and a work instruction issue button 840 is displayed, which is selected when issuing a work instruction entered in the new work instruction issuing area 820. At the bottom right of the work instruction issuing screen 80, a work instruction image area 850 is displayed, which displays an image of the work instruction to be displayed on the worker terminal 20. The work instruction image area 850 allows the administrator to check the display content of the work instruction to be issued. Here, the new work instruction issuing area 820, the work instruction text change button 830, and the work instruction issue button 840 constitute the additional work instruction input unit 13.

[0121] The work instruction event history 810 shown in FIG. 11 will be described in detail. The work instruction event history 810 in tabular form includes five items: date and time 811, event content 812, status 813, work instruction 814, and re-notification 815. One row is assigned to one work instruction event. The date and time 811 field displays the date and time when the event occurred, the event content 812 field displays the content of the event that occurred, the status 813 field displays the icon indicating the status of the work instruction explained in FIG. 9, the work instruction 814 field displays the work instruction text, and the re-notification button 816 for re-notifying is displayed in the re-notification 815 field. Here, the re-notification button 816 constitutes the additional work instruction input unit 13. The work instruction event history 810 is displayed in chronological order from top to bottom, with the most recent history displayed in the bottom row.

[0122] A specific display example of the work instruction event history 810 will be described below. This display example is a work instruction issuance screen that is displayed when a details screen display button 720, which is displayed together with an icon 719 in the status 706 item of individual warning related information 705a in the warning list 705 on the line status data display screen 70 shown in Fig. 8, is selected. In the first line of work instruction event history 810, the date and time 811 field displays "2020 / 08 / 28 10:54," the event content 812 field displays "Frequent occurrences of component non-pickup errors detected," the status 813 field displays icon 719c indicating "No improvement work assignment set," the work instruction 814 field displays nothing, and the re-notification button 816 is not displayed in the re-notification 815 field.

[0123] In the second line of the work instruction event history 810, the date and time 811 field displays "2020 / 08 / 29 23:07", the event content 812 field displays "Manual work notification operation was performed", the status 813 field displays icon 719d indicating "Exceeded number of simultaneous notifications (display ended)", and the work instruction 814 field displays "Device maintenance of the nozzle in question Please perform the re-notification" is displayed, and a re-notification button 816 is displayed in the re-notification 815 item. In other words, the administrator performed a manual work notification operation at 23:07 on 2020 / 08 / 29 to issue a work instruction stating, "Please perform device maintenance on the relevant nozzle," but the worker can recognize that the status displayed on the worker terminal 20 ended without the worker carrying out the work.

[0124] In the third line of work instruction event history 810, the date and time 811 field displays "2020 / 08 / 31 15:31," the event content 812 field displays "Re-notification operation was performed," the status 813 field displays icon 719b indicating "Improvement work completed," the work instructions 814 field displays "Please perform device maintenance on the relevant nozzle," and the re-notification 815 field does not display the re-notification button 816.

[0125] In the fourth line of work instruction event history 810, the date and time 811 field displays "2020 / 09 / 01 08:10," the event content 812 field displays "Multiple actual defects detected," the status 813 field displays icon 719a indicating "Work instruction notified (currently displayed)," the work instruction 814 field displays "Please replace the nozzle in question," and the re-notification 815 field displays a re-notification button 816.

[0126] Next, the new work instruction issuance area 820 will be specifically described. In the event in the fourth row of the work instruction event history 810, as described above, frequent occurrence of actual defects is detected, and the work instruction "replace the corresponding nozzle" is notified to the worker terminal 20, but as indicated by the icon 719a displayed in the status 813, the status is "work instruction notified (currently displayed)". Here, since the re-notification button 816 is displayed in the re-notification 815 item, the work instruction "replace the corresponding nozzle" can be displayed again on the worker terminal 20 and notified by selecting this re-notification button 816, but if the manager wants to change such a default work instruction wording prepared in advance, he or she can issue a new work instruction using the new work instruction issuance area 820. In such a case, when the manager selects the change work instruction wording button 830, inputting into the text box of the new work instruction issuance area 820 becomes possible, so the manager inputs a new work instruction wording into the new work instruction issuance area 820. Here, the manager inputs a new work instruction wording "prohibit use of the corresponding nozzle" into the new work instruction issuance area 820. Then, the manager can select the work instruction issue button 840 to issue a work instruction that temporarily changes the default work instruction text, "Please disable the corresponding nozzle."

[0127] Furthermore, the screen display of the worker terminal 20, including the work instruction to be issued, is displayed as an image in the work instruction image area 850. Here, the work instruction "Please disable the relevant nozzle" that the manager entered in the new work instruction issuance area 820 is displayed in the form of an image of the screen display of the worker terminal 20, so that the manager can confirm the content of the work instruction to be issued.

[0128] When the manager re-notifies the operator of a work instruction or issues a new work instruction on the work instruction issuing screen 80, the screen returns to the line status data display screen 70 displaying the warning list.

[0129] By using this work instruction issuing screen 80, the administrator can check the issuance history of work instructions and the status of work implementation. In addition, by using the work instruction issuing screen 80, the administrator can re-notify unimplemented or unread work instructions. Furthermore, by using the work instruction issuing screen 80, the administrator can edit the work instruction text and issue a new work instruction that differs from the default work instruction. Instructions can be issued.

[0130] (Worker screen) Fig. 12 shows an example of a work instruction display screen 90 displayed on the work instruction display unit 22 of the worker terminal 20. In Fig. 12, the leading lines of the symbols are shown with dashed lines to distinguish them from the display on the screen. This is a screen that displays the work instructions notified as a pop-up on the worker terminal 20, which is the terminal that the worker checks. On this work instruction display screen 90, the content to be notified is changed depending on the target work type (part number, mounter device, etc.) for each target line. The target line and work type corresponding to the worker terminal 20 are acquired by referring to a file set at the time of installation when the app is started.

[0131] At the top right corner of the work instruction display screen 90, a button 901 for closing the work instruction display screen 90 is displayed, and at the center below the button 901, the number of notifications 902, "1 / 3", is displayed. The number displayed in the number of notifications 902 is a number that uses the total number of work instructions (number of work instructions) notified to the worker terminal 20 as the denominator and a number indicating the number of the currently displayed work instruction as the numerator. Here, it is shown that the first of three notified work instructions is being displayed. This allows the worker to understand the amount of work to be performed. On the left and right of the number of notifications 902 are buttons for moving to the display screen of other work instructions when multiple work instructions have been notified. On the left edge, a display first button 903 for displaying the first work instruction is displayed, and on the right edge, a display previous button 904 for displaying the previous work instruction is displayed. Then, to the right of the number of notifications 902, a display next button 905 for displaying the next work instruction is displayed, and on the right edge, a display last button 906 for displaying the last work instruction is displayed. Here, since the first work instruction of three work instructions is displayed, the display first button 903 and the display previous button 904 for displaying earlier work instructions are inactive, and the display next button 905 and the display last button 906 for displaying later work instructions are active. Here, in order to enable the worker to clearly recognize the total number of work instruction notifications and the order of the displayed work instructions, the background of the notification number 902 may be displayed in a color different from that of the other display areas, such as blue, or the numbers may be displayed in white to match the background color. In addition, the active button among the display first button 903, the display previous button 904, the display next button 905, and the display last button 906 may be displayed in red, for example. By displaying the notification number 902 and the active display first button 903, etc. in different modes in this way, the worker can clearly recognize the existence of work instructions in other orders and the operations required to display the other work instructions.

[0132] Then, in the upper central part of the work instruction display screen 90, details 907 of the abnormality that has occurred, such as "multiple actual defects," and notification timing information 908 including the notification date and time of the work instruction and the time elapsed since the notification date and time, such as "2020-09-01 09:11 (2 minutes ago)," are displayed. The notification timing information 908 allows the worker to recognize the notification time of the work instruction and the time that has elapsed up to the present, and therefore to grasp the real-time nature of the work instruction.

[0133] In a work instruction display area 909 provided at the lower center of the work instruction display screen 90, a work instruction such as "Please replace the following nozzles" is displayed.

[0134] Target identification information 910 for identifying the target of the work instruction is displayed on the left side of the lower part of the work instruction display screen 90. Specifically, the target identification information 910 includes "Nozzle" as the Device Type indicating the type of device, "NOZZLE02345" as the ID, "NOZZLETYPE01" as the Device Name indicating the device name, "MOUNTER2-4" as the Mounter identifying the mounter, and "NOZZLE02345" as the ID indicating the device name. The line indicated is "Line-2", the module number indicated is "1", the stage number indicated is "1", and the nozzle pit number indicated is "1".

[0135] Further, an implementation status registration section 911 is provided on the right side of the lower part of the work instruction display screen 90. The implementation status registration section 911 includes a check box 911a and a text box 911b. The status of the implementation status registration section 911 is one of two types: not performed and completed. The status is enabled by clicking or touching the completed text box 911b. When the completed text box 911b is enabled, a check mark is displayed in the check box 911a, and information indicating that the worker has performed the work displayed and instructed on the work instruction display screen 90 is transmitted to the work information receiving section 122 of the management device 100 through the work information transmitting section 24. Here, the implementation status registration section 911 constitutes the work information input section 23. When the completed text box 911b is not enabled, the status of the work instruction displayed and instructed on the work instruction display screen 90 is not performed.

[0136] Furthermore, if the work instructions notified to the worker terminal 20 include an unexecuted work instruction, the window frame 912 is displayed in red to highlight it and blinks at one-second intervals, allowing the worker to easily and clearly recognize that there is an unexecuted work instruction.

[0137] In order to allow the work instruction display screen to be operated using a touch panel, it is desirable that the size of buttons, etc. be adapted to the specifications of the inspection device Y2, etc.

[0138] When performing work related to the mounter, it is expected that the worker will check the screen of the inspection device Y2 from the mounter X2, so if there is work that has not been performed, it is desirable to use a highlight color to make it visually easy to understand.

[0139] In addition, the system displays the necessary information without scrolling so that workers can understand the details of their work on a single screen, without the need to perform actions such as touching the screen to transition between screens. However, to make it easier for workers to understand, the system limits the number of work details displayed at a time to one.

[0140] Considering the real-time nature of work instructions and the possibility of status changes on other worker terminals 20, the worker terminal 20 performs work instruction acquisition processing every 10 seconds and automatically updates the status when there is a change. However, the work instructions themselves are not replaced.

[0141] When a plurality of work instructions are notified, the work instructions are displayed on the work instruction display screen in the order of priority.

[0142] Such a work instruction display screen on the worker terminal 20 allows the worker to be notified of work instructions in response to frequent quality fluctuations or warnings (re-)notified by the manager via the manager terminal 10, and the worker can immediately carry out the work. Furthermore, the worker inputs whether or not the instructed work has been performed on the work instruction display screen of the worker terminal 20, and the information is transmitted to the management device 100. Then, the management device 100 generates line status data including the implementation status and transmits it to the manager terminal 10, so that the manager can check the implementation status of the instructed work on the line status data display screen of the manager terminal 10.

[0143] As described above, the management system 1 including at least the manager terminal 10 and the worker terminal 20 performs the following operations in response to a work instruction (Sab1), as shown in the schematic diagram of FIG. This can assist in the realization of a function that combines the system side cycle, the worker side cycle Sab1-Sa2-Sa3-Sab1, and the worker side cycle Sb0-Sab1-Sb2-Sb3 (Sb0)-Sab1 to function adaptively, and runs a quality improvement cycle starting from an abnormality detection (Sb0), from work instruction (Sab1) to the next work instruction (Sab1), while improving the quality improvement cycle itself.
