FIG. 1 is a block diagram schematically showing board production equipment having a production line corresponding to one example of a component mounting system according to the present invention. FIG. 1 and the following figures show XYZ orthogonal coordinates in which the Z direction is the vertical direction and the X and Y directions are the horizontal directions. As shown in FIG. 1, the board production facility 1 includes three production lines La to Lc. Since these production lines La to Lc have substantially the same configuration, the production line La will be mainly described, and the production lines Lb and Lc will be denoted by corresponding reference numerals, and the description thereof will be omitted as appropriate. In this production line La, a printer 2, an inspection machine 3a, a plurality (three) of component mounters 4a to 4c, an inspection machine 3b, a reflow furnace 5, and an inspection machine 3c are arranged in series in the X direction, which is the board transfer direction. line up.

The printer 2 prints the application material (solder) on the substrate by screen printing. The component mounters 4a to 4c have a configuration which will be described later with reference to FIG. The reflow 5 heats the board on which the components are mounted by the component mounters 4a to 4c to melt the solder that joins the component and the board. Each of the inspection machines 3a to 3c is a device for inspecting the appearance of an object, and performs inspection based on a two-dimensional or three-dimensional image of the object. Of these, the inspection machine 3a inspects the quality of the solder printed on the board by the printer 2 before the board is carried into the component mounter 4a, and the inspection machine 3b inspects the board by the component mounters 4a to 4c. The quality of component mounting on the board is inspected before the board is brought into the reflow furnace 5, and the inspection machine 3c inspects the quality of the solder heated by the reflow furnace 5. In this way, the production line La performs solder printing, component mounting, and reflow on the board while transporting the board in the X direction, thereby producing a component-mounted board (component-mounted board).

The substrate production facility 1 also includes a management device 6 that manages the production lines La to Lc. This management device 6 includes a control section 61 , a storage section 62 , a communication section 63 , a display 64 and an input device 65 . The control unit 61 is a processor such as a CPU (Central Processing Unit), and executes calculations required for managing the production lines La, Lb, and Lc.

The storage unit 62 is composed of an HDD (Hard Disk Drive) or the like, and stores data and programs required for managing the production lines La, Lb, and Lc. In particular, the storage unit 62 stores a production management program 621, and the control unit 61 executes the production management program 621 to execute board production management, which will be described later. This production management program 621 is provided in a state of being recorded in a recording medium 69 so as to be readable by a computer. The recording medium 69 is, for example, an HDD installed in an external computer. Note that the recording medium 69 is not limited to the HDD, and may be, for example, a USB flash drive, an optical disc, or the like.

The communication unit 63 performs wired or wireless communication with the devices 2, 3a to 3c, 4a to 4c, and 5 provided on the production lines La to Lc. The communication unit 63 collects logs 622 indicating operation histories of the devices 2, 3a to 3c, 4a to 4c, and 5 in response to commands from the control unit 61, for example, and stores them in the storage unit 62. FIG.

The display 64 displays information, which will be described later, to the administrator, and the input device 65 accepts input operations by the administrator. The management device 6 is composed of a personal computer or a tablet. In the former case, the input device 65 is a mouse or keyboard, and in the latter case, the display 64 and the input device 65 are integrated with a touch panel display. Furthermore, in the former case, the administrator can execute various input operations such as selection or designation, which will be described later, by clicking or hovering a target portion displayed on the display with a mouse. Various input operations such as selection or specification, which will be described later, can be executed by touching a finger or an instrument to a target location.

FIG. 2 is a partial plan view schematically showing a component mounting machine provided in each production line of the board production facility of FIG. In the figure, the component mounters 4a to 4c are represented as the component mounter 4 without distinction. The component mounter 4 includes a pair of conveyors 41 arranged in parallel in the X direction, and conveys the board 10 by these conveyors 41 . That is, the component mounter 4 mounts components on the board 10 that has been transported from the upstream side in the X direction to the mounting work position (the position of the board 10 in FIG. The conveyor 41 carries out from the mounting work position to the downstream side in the X direction. Note that mounting a component on the substrate 10 indicates an operation of placing a component on solder printed on the substrate 10 .

Two component supply units 42 are arranged in the X direction on each side of the pair of conveyors 41 in the Y direction, and in each component supply unit 42, a plurality of feeders F are arranged in the X direction. Each feeder F is provided with a component supply reel on which a component supply tape containing small pieces of components such as integrated circuits, transistors, capacitors, etc. are wound at predetermined intervals. By intermittently feeding the component supply tape pulled out from the reel, the component is supplied to the leading end of the tape.

A feeder ID for identifying the feeder F is attached to the feeder F. FIG. This feeder ID is unique information for each feeder F, and the feeder ID is different if the feeder F is different. Further, the component supply reel is assigned a component ID for identifying the component accommodated in the component supply reel. This component ID is information unique to each component supply reel.

The mounter 4 is provided with a pair of Y-axis rails 431 extending in the Y direction, a Y-axis ball screw 432 extending in the Y direction, and a Y-axis motor 433 that drives the Y-axis ball screw 432 to rotate. A pair of Y-axis rails 431 supports an X-axis beam 434 extending in the X direction so as to be movable in the Y direction. An X-axis ball screw 435 extending in the X-direction and an X-axis motor 436 that rotationally drives the X-axis ball screw 435 are attached to the X-axis beam 434 . The X-axis beam 434 supports the head unit 44 movably in the X direction, and the head unit 44 is fixed to the nut of the X-axis ball screw 435 . Therefore, the Y-axis motor 433 rotates the Y-axis ball screw 432 to move the head unit 44 in the Y direction, and the X-axis motor 436 rotates the X-axis ball screw 435 to move the head unit 44 in the X direction. can be done.

The head unit 44 has a plurality (six) of mounting heads 45 arranged in the X direction. Each head unit 44 has an elongated shape extending in the Z direction, and a nozzle for sucking a component is detachably attached to the lower end of the head unit 44 . The head unit 44 carries out component mounting by transferring the component from the feeder F to the substrate 10 using a nozzle.

That is, the mounting head 45 causes the nozzle to face the tip of the feeder F from above. Next, the mounting head 45 descends to bring the component supplied to the tip of the feeder F into contact with the nozzle. Subsequently, the mounting head 45 ascends while sucking the component with the nozzle. When the mounting head 45 has thus completed picking up the components from the feeder F, it moves above the substrate 10 . Then, the mounting head 45 mounts the component on the substrate 10 by canceling the suction of the component by the nozzle.

Incidentally, an upward-facing component recognition camera 46 is arranged between the two component supply units 42 arranged in the X direction, and the component recognition camera 46 confirms whether or not there is a pickup error based on the captured image. That is, the nozzle moving from the feeder F to the substrate 10 for component mounting passes through the field of view of the component recognition camera 46, and the component recognition camera 46 takes an image at the timing when the nozzle reaches the field of view. Then, the component recognition camera 46 detects the occurrence of a pick-up error based on the presence or absence of a component sucked by the nozzle, the inclination of the component, and the like. Further, when it is confirmed that the pick-up error has occurred, the mounting head 45 returns the nozzle to above the tip of the feeder F and tries again to pick up the component with the nozzle.

Further, a board recognition camera 47 is attached to the head unit 44 so as to face downward, and the board recognition camera 47 moves in the X direction and the Y direction along with the head unit 44 . The board recognition camera 47 recognizes the position of the board 10 based on an image of the fiducial mark attached to the board 10 carried into the mounting work position, which is taken from above. Then, based on this recognition result, the position of the component to be mounted by the mounting head 45 in the X direction and the Y direction is adjusted. In addition, this component mounter 4 is also used for imaging the components mounted on the board.

Next, board production management executed by the management device 6 in the board production facility 1 of FIG. 1 will be described. FIG. 3 is a diagram schematically showing an example of a production control screen displayed on the display of the control device. This production control screen S has a setting section Sa, a selection section Sb, and a detail section Sc.

The setting part Sa is used for setting display targets on the production control screen S. FIG. In other words, by operating the input device 65, the administrator sets the target period (start date and time to end date and time) and sets the target production line (line name) among the production lines La to Lc to the setting unit Sa. can be executed. In addition, in the example of FIG. 3, the production line La is set as the target production line.

The selection section Sb displays graphs B1, B2, B3, and B4 respectively showing temporal changes in the OEE (overall equipment efficiency), hourly operating rate, performance operating rate, and non-defective product rate in the target production line La during the target period. These graphs B1, B2, B3, and B4 are calculated by the control unit 61 based on the log 622 collected from the target production line La. Each of the graphs B1, B2, B3, and B4 divides the target period equally into unit periods (one day) shorter than the target period and shows values in each unit period. For example, a graph B1 showing temporal changes in OEE shows daily OEE for each day of the target period. Similarly, graphs B2, B3, and B4 showing temporal changes in hourly operating rate, performance operating rate, and non-defective product rate show daily hourly operating rate, performance operating rate, and non-defective product rate, respectively, for each day of the target period. Note that the unit period is not limited to one day, and may be, for example, one hour or half an hour.

The administrator selects one component by designating one of the graphs B2, B3, and B4 of each component of OEE such as the hourly operating rate, the performance operating rate, and the non-defective product rate displayed in the selection section Sb. An input operation to select can be performed on the input device 65 . Based on the log 622, the control unit 61 calculates the occurrence status of the event that occurred in the target production line La during the target period and has a correlation with the one component, and displays it in the detail section Sc. At this time, the administrator can specify a specified date (specified unit period) from the target period, and the occurrence status of the event on the specified date is displayed in the detail portion Sc. Next, this point will be described in detail.

FIG. 4 is a diagram showing an example of a production control screen when hourly operating rate is selected. In other words, when a specified date (for example, April 7) is specified from the graph B2 of the hourly operating rate, the control unit 61 stops the component mounters 4a, 4b, and 4c of the target production line La by the specified time. It is treated as an event that correlates with availability. Then, the control unit 61 displays a graph C1 indicating the stop time (apparatus stop time) of each of the component mounters 4a, 4b, and 4c on the specified date in the detail portion Sc.

The stop time for each device shown in the graph C1 of FIG. 4 is the cumulative time required for each of the component mounters 4a, 4b, and 4c to stop for a long period of time. That is, the cumulative time of long-term stoppages occurring in the component mounters 4 is displayed for each of the component mounters 4a, 4b, and 4c. This long-term stop consists of a relatively long-term Type 1 stop (so-called “doka stop”) that can occur in the mounters 4a, 4b, and 4c, and a relatively short-term Type 2 stop that is different from the Type 1 stop. It is a type 1 stop among stops (so-called "chocolate stops"). Based on this graph C1, the manager can confirm the occurrence of long-term stoppages in each of the component mounters 4a, 4b, and 4c.

Incidentally, various methods are conceivable for distinguishing between a type 1 stop and a type 2 stop that has occurred. One example is a method of classifying a stop of a predetermined reference time or more as a first-class stop, and classifying a stop of less than the reference time as a second-class stop. Another example is a method in which an administrator pre-classifies each outage into either a Type 1 outage or a Type 2 outage depending on the cause of the outage.
