Description

This specification discloses a management device and a management method.

Conventionally, a management device has been proposed for managing a mounting system that acquires component maintenance information from the component's IC tag, determines when maintenance is due, and issues a warning and stops operation of the mounting device when maintenance is due (see, for example, Patent Document 1). This management device is said to be able to detect when component maintenance is due collectively and quantitatively. Another proposed mounting device included in a mounting system is one that is equipped with a display device on the mounting head, calculates cumulative usage by accumulating the number of shots of the mounting head, and displays this cumulative usage number as an indicator on the display device (see, for example, Patent Document 2). This device makes it possible to accurately grasp the usage status of the component units of the mounting device.

Japanese Patent Application Laid-Open No. 2006-108322 JP 2015-176892 A

However, the mounting systems described in Patent Documents 1 and 2 were unable to grasp the overall usage status of the mounting device. Since the maintenance cycle for the device can vary depending on the part being maintained, there was a desire to grasp the maintenance status of the entire device.

The present disclosure has been made in consideration of these issues, and its primary purpose is to provide a management device and management method that can grasp the usage status of components that make up an implementation system and more easily create maintenance plans.

The management device and management method disclosed in this specification employ the following measures to achieve the above-mentioned primary objective.

The management device disclosed in this specification is
A management device for maintenance of a mounting system including a mounting device that mounts components on a substrate, the management device comprising: a pickup unit that picks components; and a substrate processing unit that moves and fixes substrates,
a storage unit that stores correspondence information in which a maintenance time corresponding to the number of operations and/or operation time is set for each item of the components of the mounting device;
a control unit that acquires information on usage conditions including the number of times of operation and/or operation time from the mounting device, and displays and outputs a list of items that need maintenance based on the acquired information and the corresponding information in a visibly recognizable manner;
It is equipped with the following.

This management device acquires usage information, including the number of times the mounting device has been operated and/or the amount of time it has operated, from the mounting device, and based on this acquired information and corresponding information that sets the maintenance timing corresponding to the number of times the device has been operated and/or the amount of time it has operated for each component of the mounting device, displays and outputs a list that makes it easy to see which items are due for maintenance. Because this management device displays maintenance timing information for each item in list format, it is possible to understand the usage status of the components that make up the mounting system and more easily create maintenance plans.

In the management device disclosed herein, the control unit may associate with a component that is due for maintenance unusable information that renders the component unusable, and output the unusable information associated with the component to a device that has the component. By rendering a component that is due for maintenance unusable, this management device can perform appropriate maintenance.

In a management device that outputs unusable information, the mounting system may include a maintenance device that maintains the component, and the control unit may output the unusable information and, upon receiving maintenance completion information from the maintenance device indicating that the component that is due for maintenance has been maintained, output release information to the device that owns the component, which releases the unusable state. This management device enables the component to be used based on the information from the maintenance device, allowing for appropriate maintenance operations.

Alternatively, the management device of the present disclosure may include:
A management device for maintenance of a mounting system including a mounting device that mounts components on a substrate, the mounting device having a collection unit that collects components and a substrate processing unit that moves and fixes the substrate, and a maintenance device that maintains the components,
a storage unit that stores correspondence information in which a maintenance time corresponding to the number of operations and/or operation time is set for each item of the components of the mounting device;
a control unit that acquires information on usage status including the number of times of operation and/or operation time from the mounting device, associates unusable information that makes the component in an unusable state when maintenance is due to be performed with the component based on the acquired information and the correspondence information, outputs the unusable information associated with the component to a device having the component, and then, upon acquiring maintenance completion information from the maintenance device indicating that maintenance has been performed on the component that is in the maintenance period, outputs release information that releases the unusable state to the device having the component;
It may also be provided with:

This management device acquires usage status information, including the number of times and/or the duration of operation, from the mounting device. Based on this acquired information and correspondence information in which the maintenance period corresponding to the number of times and/or the duration of operation is set for each component of the mounting device, it associates unusable information with the component that has reached the maintenance period, and outputs the unusable information associated with the component to the device that has the component. When the management device subsequently acquires maintenance completion information from the maintenance device indicating that the component that has reached the maintenance period has been maintained, it outputs release information to the device that has the component that releases the unusable state. This management device disables the component that has reached the maintenance period, while enabling the component to be used based on the information from the maintenance device, allowing for appropriate maintenance.

In a management device for a mounting system that includes a maintenance device, the maintenance device may be equipped with a cleaning unit that cleans the components of the collection unit of the mounting device included in the mounting system and/or an oil supply unit that oils the components. This management device can appropriately perform maintenance such as cleaning and oiling the components.

A management device that outputs unusable information may include an input unit that inputs instructions from a worker, and after outputting the unusable information, when maintenance completion information indicating that the component associated with the unusable information has been maintained is input from the input unit, the control unit may output release information to the device that contains the component, releasing the unusable state. With this management device, the worker can input information indicating that maintenance work has been performed, allowing appropriate maintenance to be performed.

In the management device disclosed herein, the collection unit may include, as its components, one or more of a filter, syringe, valve, and valve sealing member arranged in the pressure path, and/or one or more of a gear, guide shaft, and cam follower as mechanical mechanisms, and/or one or more of a prism arranged in the optical path. This management device can grasp the usage status of these components, making it easier to create maintenance plans.

The management method of the present disclosure includes:
A management method for maintenance of a mounting system including a mounting device that mounts components on a substrate, the mounting system comprising a pickup unit that picks components and a substrate processing unit that moves and fixes substrates, the method comprising:
(a) acquiring correspondence information in which a maintenance timing corresponding to the number of operations and/or operation time is set for each component item of the mounting device;
(b) acquiring information on the usage status including the number of times of operation and/or the operation time from the mounting device;
(c) displaying in a list format which items are due for maintenance based on the information acquired in step (b) and the corresponding information so that the items can be visually identified;
It may also include.

This management method, like the management device described above, displays maintenance timing information for each item in list format, making it possible to understand the usage status of the components that make up the implementation system and more easily create maintenance plans. Note that this management method may employ various aspects of the management device described above, or may include additional steps that implement each function of the management device described above.

Alternatively, the management method of the present disclosure may include:
A management method for maintenance of a mounting system including a mounting device that mounts components on a substrate, the mounting device comprising a pickup unit that picks components and a substrate processing unit that moves and fixes substrates, and a maintenance device that maintains the components, comprising:
(a) acquiring correspondence information in which a maintenance timing corresponding to the number of operations and/or operation time is set for each component item of the mounting device;
(b) acquiring information on the usage status including the number of times of operation and/or the operation time from the mounting device;
(c) based on the information acquired in step (b) and the correspondence information, associating with the component unusable information that makes the component unusable when maintenance is due, and outputting the unusable information associated with the component to a device having the component;
(d) after outputting the unusable information in step (c), when maintenance completion information indicating that the component due for maintenance has been maintained is obtained from the maintenance device, outputting release information for releasing the unusable state to the device having the component;
It may also include.

In this management method, similar to the management device described above, components that need maintenance are disabled, but the components are made available for use based on information from the maintenance device, allowing for appropriate maintenance. Note that this management method may employ various aspects of the management device described above, and may also include additional steps that implement the functions of the management device described above.

The mounting system 10 is a system that executes a process of mounting, for example, a component P (see FIG. 2) on a substrate S. This mounting system 10 includes a mounting device 11, a head maintenance device 80, and a management computer (PC) 90. The mounting system 10 is configured as a mounting line in which multiple mounting devices 11 are arranged from upstream to downstream. For ease of explanation, only one mounting device 11 is shown in FIG. 1. In this embodiment, the left-right direction (X-axis), front-back direction (Y-axis), and up-down direction (Z-axis) are as shown in Figures 2 and 3.

As shown in FIG. 2, the mounting device 11 includes a board processing unit 12, a component supply unit 14, a component imaging unit 16, an operation panel 18, a mounting unit 20, and a control unit 31. The board processing unit 12 is a unit that loads, transports, fixes at the mounting position, and transports boards S. The board processing unit 12 has a pair of conveyor belts that are spaced apart at the front and rear of the board processing unit 12 and span the left and right directions as shown in FIG. 2. The boards S are transported by these conveyor belts. The component supply unit 14 is a unit that supplies components P to the mounting unit 20. The component supply unit 14 has multiple feeders equipped with reels around which tape containing components P is wound, and a tray unit that contains trays on which components P are arranged, and is detachably attached to the front of the mounting device 11. The component imaging unit 16 is a camera that captures images of components P picked up and held by the mounting head 22 from below. The component imaging unit 16 is disposed between the board processing unit 12 and the component supply unit 14, and its imaging range is above the component imaging unit 16. The operation panel 18 is a unit for exchanging information with the worker, and has a display unit that displays the screen and an operation unit that the worker operates.

The mounting unit 20 is a unit that collects components P from the component supply unit 14 and places them on a substrate S fixed to the substrate processing unit 12. The mounting unit 20 includes a head moving unit 21, a mounting head 22, a rotating body 23, a syringe 24, and a nozzle 25. The mounting unit 20 also includes an R-axis drive unit 26, a Q-axis drive unit 27, and a Z-axis drive unit 28. The head moving unit 21 includes a slider that moves in the X and Y directions along a guide rail, and a motor that drives the slider. The mounting head 22 is removably attached to the slider and moved in the X and Y directions by the head moving unit 21. One or more nozzles 25 are removably attached to the underside of the mounting head 22 via the rotating body 23. Multiple nozzles 25 (e.g., 16, 8, or 4 nozzles) are attached to the rotating body 23 via syringes 24, allowing multiple components P to be collected at one time. The nozzle 25 is a collection member that uses negative pressure to collect components and is removably attached to the mounting head 22 via a syringe 24. The nozzle 25 picks up components when negative pressure is supplied to it via a pressure path and mechanical valve (not shown), and releases the components when positive pressure is supplied. A negative pressure filter is provided in the pressure path of the mounting head 22 to prevent the intrusion of foreign matter. A sealing O-ring is also provided inside the mechanical valve. The collection member that collects components P may be a mechanical chuck that grips and collects components P. A side camera 48 is provided to the side of the mounting head 22 to capture images of the area near the tip of the nozzle 25 from the side (see Figure 3). Prism glass is provided in the optical path of the side camera 48.

As shown in Figure 3, the mounting head 22 includes a rotor 23, a valve drive device 46, an R-axis drive unit 26, a Q-axis drive unit 27, and a Z-axis drive unit 28. The rotor 23 is a cylindrical member and includes a syringe 24, a nozzle 25, and a valve operating lever 45. The syringe 24 is a cylindrical member with its longitudinal direction in the Z-axis direction, and multiple syringes 24 (e.g., eight) are provided at predetermined intervals around the circumference of the rotor 23. A sealing O-ring is disposed inside the syringe 24. The nozzle 25 is replaceably attached to the tip of each syringe 24. The valve operating lever 45 is a lever that operates a mechanical valve and is provided for each nozzle 25 along the circumference of the rotor 23. The valve operating lever 45 is an alternate type lever that can be switched between a negative pressure supply position that supplies negative pressure to the nozzle 25, an atmospheric pressure supply position that supplies atmospheric pressure to the nozzle 25, and a positive pressure supply position that supplies positive pressure to the nozzle 25.

The valve drive device 46 is configured to be able to raise and lower the valve operating lever 45 individually. The valve drive device 46 has a clamping portion 47 that clamps the horizontal surface of the valve operating lever 45 from above and below, and by raising and lowering the clamping portion 47, the valve operating lever 45 is positioned to any position. As shown in Figure 4, the clamping portion 47 is rotatably attached around an arm shaft 49 and is held in a position that is approximately perpendicular to the cylindrical side surface of the rotating body 23. A cam follower 50 that abuts against the valve operating lever 45 is arranged at the tip of the clamping portion 47.

As shown in FIG. 3, the R-axis drive unit 26 includes an R-axis 51 and an R-axis motor 54. The R-axis 51 extends vertically, with its lower end attached to the central axis of the rotor 23. The R-axis motor 54 rotates a gear 53 that meshes with an R-axis gear 52 provided at the upper end of the R-axis 51. The R-axis drive unit 26 rotates (revolves) the R-axis 51 via the gear 53 and the R-axis gear 52 using the R-axis motor 54, thereby causing the multiple syringes 24 supported on the rotor 23 to rotate (revolve) in the circumferential direction together with the multiple nozzles 25.

The Q-axis drive unit 27 includes two upper and lower Q-axis gears 61 and 62, gears 63 and 64, and a Q-axis motor 65. The upper and lower Q-axis gears 61 and 62 are inserted coaxially and relatively rotatably onto the R-axis 51. Gear 63 is provided on the top of each syringe 24 and meshes with the lower Q-axis gear 61 so that it can slide vertically. The Q-axis motor 65 rotates gear 64 that meshes with the upper Q-axis gear 62. The Q-axis drive unit 27 rotates the Q-axis gears 61 and 62 using the Q-axis motor 65, thereby rotating gear 63 that meshes with the Q-axis gear 61 and rotating each syringe 24 around its central axis in the same direction and by the same amount. Accordingly, the nozzle 25 also rotates (spins on its axis).

The Z-axis drive unit 28 is configured to be able to raise and lower the syringes 24 individually along the Z-axis direction. The Z-axis drive unit 28 includes a Z-axis slider 71, a Z-axis guide shaft (not shown), and a Z-axis motor 73. The Z-axis slider 71 is attached to a ball screw 72 extending in the vertical direction so that it can be raised and lowered. The Z-axis slider 71 includes a clamping portion 76 that clamps the horizontal surface of the engagement piece 41 extending from the syringe 24 (see Figure 5). The Z-axis motor 73 raises and lowers the Z-axis slider 71 along the Z-axis guide shaft by rotating the ball screw 72. The Z-axis drive unit 28 drives the Z-axis motor 73 to raise and lower the Z-axis slider 71 along the ball screw 72, thereby raising and lowering the syringe 24 and nozzle 25 integrated with the Z-axis slider 71. The clamping portion 76 clamps the engagement piece 41 of the syringe 24 and raises and lowers it. A cam follower 78 is provided at the tip of the clamping portion 76. The syringe 24 is inserted into a spring 42, which positions the syringe 24 in a fixed position in the vertical direction.

As shown in FIG. 2, the control unit 31 is configured as a microprocessor centered around a CPU 32, and includes a memory unit 33 that stores various data. The control unit 31 outputs control signals to the board processing unit 12, component supply unit 14, component imaging unit 16, and mounting unit 20, and inputs signals from the mounting unit 20, component supply unit 14, and component imaging unit 16. The memory unit 33 stores mounting condition information, including information such as the placement order and placement coordinates of components P, as well as use prohibition information 34 that prohibits the use of specific mounting heads 22. The mounting condition information and use prohibition information 34 are obtained from the management PC 90 and stored in the memory unit 33.

The head maintenance device 80 is a device that performs maintenance and inspection of the mounting head 22. As shown in FIG. 1, the head maintenance device 80 comprises a control unit 81, a memory unit 83, a head mounting unit 84, a cleaning unit 85, an oil supply unit 86, an inspection unit 87, and an operation panel 88. The control unit 81 is configured as a microprocessor centered on a CPU 82. The memory unit 83 stores information about the mounting head 22 to be maintained. The head mounting unit 84 has a structure similar to the slider of the head movement unit 21 and is configured to be able to mount multiple types of mounting heads 22. The cleaning unit 85 is a unit that performs a process to clean the components of the mounting head 22. This cleaning unit 85 cleans the components of the mounting head 22 by supplying compressed air to, for example, a syringe 24 to remove foreign matter from the air piping. The cleaning unit 85 is connected to a pressure device used throughout the mounting system 10, and compressed air is supplied from this pressure device. The cleaning unit 85 may use a cleaning fluid to clean components that require lubrication, such as gear mechanisms. The oil supply unit 86 supplies lubricant (e.g., grease or lubricating oil) to the various gears described above. The oil supply unit 86 includes a supply pipe, a cylinder, and an oil supply nozzle. The supply pipe is made of a flexible resin material. The cylinder contains lubricant supplied from the outside through the supply pipe and uses air pressure to discharge the lubricant from the oil supply nozzle. After the mounting head 22 is attached to the head attachment unit 84, the oil supply unit 86 moves the oil supply nozzle to the oil supply position for each gear. The inspection unit 87 is a unit that inspects whether the operation of the mounting head 22 is within a normal allowable range. For example, the inspection unit 87 measures the time required for the up and down movement of the syringe 24 and outputs the measured time to the control unit 81. The control unit 81 determines whether the measured time is within a specified range. The operation panel 88 is a unit for exchanging information with the worker, and has a display unit that displays the screen and an operation unit that the worker operates.

The management PC 90 is configured as a server that manages information about each device in the mounting system 10. As shown in FIG. 1, the management PC 90 includes a control unit 91, a memory unit 93, a display unit 98, and an input device 99. The control unit 91 is configured as a microprocessor centered around a CPU 92. The memory unit 93 of the management PC 90 stores head management information 94 and correspondence information 95. The head management information 94 is a database that manages the usage status of each mounting head 22, including the number of operations and operating time. As shown in FIG. 6, this head management information 94 includes the head ID of the mounting head 22, the ID of the rotor 23, the ID of the syringe 24, and information such as their operation time and number of operations. As shown in FIG. 7, the correspondence information 95 is information that sets the maintenance period corresponding to the number of operations and operating time for each component of the mounting device 11. The correspondence information 95 associates maintenance items (maintenance targets), the operating time or number of times maintenance should be performed, the details of the maintenance work, and the time required for the maintenance work. As shown in FIG. 7 , maintenance items include the negative pressure filter, the inside of the syringe, the O-ring inside the syringe, the Q-axis gears 61 and 62, the O-ring inside the mechanical valve, the arm shaft 49 of the mechanical valve, the R-axis gear 52, the Z-axis ball screw 72, the Z-axis guide shaft, the cam follower 50 for driving the mechanical valve, and the prism glass surface of the side camera 48. The maintenance items may also include a battery for a memory element. Maintenance work includes inspection, cleaning, lubrication, and replacement. For example, the correspondence information 95 defines appropriate maintenance work for each maintenance item based on the number of operations and operating time, based on the fact that lubrication or cleaning is required when the number of operations of a component exceeds a predetermined number, or that lubricating oil deteriorates after a predetermined period of operation. This correspondence information 95 stipulates that cleaning work should be performed when a first work time is reached, refueling work should be performed when a second work time that is longer than the first work time is reached, replacement work should be performed when a third work time that is longer than the second work time is reached, and one of cleaning, refueling, and inspection should be performed when the number of operations reaches a predetermined number. The display unit 98 is a display that displays various information. The input device 99 includes a keyboard, mouse, etc. through which the worker inputs various commands.

Next, the operation of the mounting system 10 of this embodiment configured as described above will be described. First, the maintenance management process for the mounting head 22 executed by the control unit 91 of the management PC 90 will be described. FIG. 8 is a flowchart illustrating an example of a maintenance management process routine executed by the control unit 91 of the management PC 90. This routine is stored in the storage unit 93 and executed while the mounting system 10 is in operation. Here, the maintenance management of the mounting head 22 as a component will be mainly described. When this routine starts, the CPU 92 first determines whether usage status information has been acquired from the mounting device 11 (S100). The usage status information includes the ID of the corresponding mounting head 22, the number of operations of the components of the mounting device 11, the operation time, and other usage information, and is transmitted from the mounting device 11 as appropriate. The components of the mounting device 11 include the maintenance targets described above. The number of operations of the components includes the number of suction attempts and failures of each syringe 24. When the usage status information is acquired, the CPU 92 updates the head management information 94 (S110), reads and acquires the correspondence information 95 from the storage unit 93 (S120), and determines whether there are any items that require maintenance work (S130) based on the acquired usage status information and the correspondence information 95. In S130, it determines whether there are any items that have reached the maintenance time specified in the correspondence information 95. If there are any items that require maintenance work, the CPU 92 causes the display unit 98 to display and output a maintenance display screen 35 that visually displays in a list format whether the maintenance items have reached their maintenance time (S140).

Figure 9 is an explanatory diagram showing an example of a maintenance display screen 35. This maintenance display screen 35 includes an arrangement of a cursor 36, a maintenance content display field 37, an information display field 38, and an OK key 39. The cursor 36 operates based on the operation of the input device 99 and is operated to select display fields, keys, etc. The maintenance content display field 37 is a field that displays a correspondence between the maintenance item, the work content, and the reason for the maintenance corresponding to the maintenance timing. The maintenance content display field 37 also displays information such as the time required for the maintenance work, whether the head maintenance device 80 is available, and whether the corresponding mounting head 22 (component) will be unavailable before the maintenance work. The information display field 38 is a field that displays information to be communicated to the worker. The OK key 39 is a key that the worker presses after confirming the information. The worker confirms the contents of the maintenance content display field 37 and the information display field 38 and presses the OK key 39.

After S140, the CPU 92 outputs unusable information to the mounting device 11, disabling the component that requires maintenance (S150). The mounting device 11 blocks the use of the disabled component (e.g., the mounting head 22). The CPU 92 then stores the head management information 94, which associates the unusable information with the component, in the storage unit 93 (S160). After S160, or when no usage status information was acquired in S100, or when no items requiring maintenance were found in S130, the CPU 92 determines whether maintenance completion information was acquired (S170). The maintenance completion information is information indicating that maintenance work has been performed on the component that requires maintenance. The maintenance completion information is output from the head maintenance device 80 or manually input by the operator via the operation panel 18, operation panel 88, input device 99, or the like. When the maintenance completion information is acquired, the CPU 92 deletes the corresponding unusable information from the head management information 94 and outputs release information to release the unusable state to the device (mounting device 11) that has the corresponding component (S180). The mounting device 11, upon receiving this, releases the unusable state of the corresponding component. Then, after S180, or if the maintenance completion information was not acquired in S170, the CPU 92 executes the processing from S100 onwards. In this way, the management PC 90 updates the head management information 94 while outputting the unusable information and release information.

Next, we will explain the execution of the maintenance process for the mounting head 22 performed by the head maintenance device 80. Figure 10 is a flowchart showing an example of a maintenance execution process routine executed by the control unit 81 of the head maintenance device 80. This routine is stored in the memory unit 83 and executed after the mounting head 22 is attached to the head attachment unit 84. When this routine starts, the CPU 82 acquires head management information 94 from the head maintenance device 80 and acquires information about the mounting head 22 attached to the head attachment unit 84 (S200). Next, the CPU 82 determines whether the maintenance item due for maintenance includes cleaning (S210). If cleaning is required, the CPU 82 causes the cleaning unit 85 to perform the corresponding cleaning (S220) and outputs maintenance completion information to the management PC 90 (S230). For example, if the syringe 24 is due for cleaning, the cleaning unit 85 supplies compressed air to the corresponding syringe 24 to clean its interior. The CPU 92 also outputs maintenance completion information to the management PC 90 indicating that maintenance has been performed on the syringe 24.

After S230 or in S210, if the maintenance item due for maintenance does not require cleaning, the CPU 82 determines whether the maintenance item due for maintenance requires refueling (S240). If refueling is required, the CPU 82 causes the refueling unit 86 to perform the corresponding refueling (S250) and outputs maintenance completion information to the management PC 90 (S260). For example, if the maintenance of the Q-axis gears 61 and 62 is due for refueling, the refueling unit 86 refuels the corresponding gear. After S260 or in S240, if the maintenance item due for maintenance does not require refueling, the CPU 82 determines whether the maintenance item requires inspection (S270). If inspection processing is required, the CPU 82 causes the inspection unit 87 to perform the corresponding inspection processing (S280) and determines whether the measurement value obtained by the inspection processing is within the acceptable range (S290). If the measured value is within the allowable range, the CPU 82 outputs the corresponding maintenance completion information to the management PC 90 (S300). On the other hand, if the measured value is not within the allowable range, the CPU 82 associates unusable information with the corresponding maintenance item, outputs this information to the management PC 90 and the mounting device 11, displays an error on the operation panel 88, and notifies the worker of this information (S310). The worker confirms this and performs disassembly and cleaning of the corresponding component or part replacement, etc. The CPU 82 ends this routine after S300, S310, or if inspection processing is not required in S270.

Next, the mounting process executed by the mounting device 11 will be described. FIG. 11 is a flowchart showing an example of a mounting process routine executed by the control unit 31 of the mounting device 11. This routine is stored in the storage unit 33 and is executed after an operator inputs a command to start the mounting process. When this routine starts, the CPU 32 determines whether or not unusable information has been acquired from the management PC 90 and/or the head maintenance device 80 (S400). If unusable information has been acquired, the CPU 32 sets the corresponding component to an unusable state (S410). That is, if a component due for maintenance is attached to the mounting device 11, the CPU 32 blocks its use. After S410, or if unusable information has not been acquired in S400, the CPU 32 determines whether or not release information has been acquired (S420). If release information has been acquired, the CPU 32 performs processing to release the unusable state of the corresponding component (S430).

After S430, or if no release information was obtained in S420, the CPU 32 determines whether any components mounted on the mounting device 11 are unusable (S440). If no unusable components are present, the CPU 32 performs the mounting process (S450). In the mounting process, components P are collected from the component supply unit 14 and placed on the board S fixed to the board processing unit 12. The mounting device 11 blocks the use of components due for maintenance because they may be at risk of reduced operational accuracy or malfunction, prompting maintenance work. After performing the mounting process, the CPU 32 outputs usage status information, including operating time and number of operations, to the management PC 90 to update these information (S460). The management PC 90, having obtained the usage status information, updates the head management information 94. On the other hand, if an unusable component is mounted on the mounting device 11 in S440, the CPU 32 notifies the operator of an error to that effect (S470). At this time, the CPU 32 may display the maintenance display screen 35 on the operation panel 18. Having confirmed this, the worker performs maintenance work on the corresponding component . After S460 and S470, the CPU 32 determines whether or not production of the board S has been completed (S480), and if production of the board S has not been completed, executes the processing from S400 onwards. On the other hand, if production of the board S has been completed, this routine ends.

Here, we will clarify the correspondence between the components of this embodiment and the components of the present disclosure. The management PC 90 of this embodiment corresponds to the management device of this disclosure, the head maintenance device 80 corresponds to the maintenance device, and the mounting device 11 corresponds to the mounting device. Furthermore, the memory unit 93 of this embodiment corresponds to the memory unit of this disclosure, the control unit 91 corresponds to the control unit, the cleaning unit 85 corresponds to the cleaning unit, and the oil supply unit 86 corresponds to the oil supply unit. Note that this embodiment also clarifies an example of the management method of the present disclosure by explaining the operation of the control unit 91.

The management PC 90 of this embodiment described above acquires usage status information, including the number of operations and/or operation time, from the mounting device 11, and based on this usage status information and correspondence information 95, in which the maintenance timing corresponding to the number of operations and/or operation time is set for each component of the mounting device 11, displays and outputs in a list format which allows a visual indication of which items are due for maintenance. Because the management PC 90 displays the maintenance timing information for each item in a list format, it is possible to grasp the usage status of the components that make up the mounting system 10 and more easily create maintenance plans. Furthermore, the control unit 91 associates with the component unusable information that renders the component unusable when maintenance is due, and outputs the unusable information to the device that owns the component. By rendering the component unusable when maintenance is due, the management PC 90 can perform appropriate maintenance. Furthermore, the mounting system 10 includes a head maintenance device 80 that maintains the mounting head 22 as a component. After outputting the disable information, the control unit 91 receives maintenance completion information from the head maintenance device 80 indicating that the component due for maintenance has been maintained, and then outputs release information to the device that owns the component to release the disable state. This management PC 90 enables the component to be used based on the information from the head maintenance device 80, allowing for appropriate maintenance operations.

The head maintenance device 80 also includes a cleaning unit 85 that cleans the components of the mounting head 22 of the mounting device 11, and an oiling unit 86 that oils the components. This head maintenance device 80 can properly perform maintenance such as cleaning and oiling the components. The management PC 90 also includes an input device 99 that inputs instructions from the worker, and after outputting the unusable information, the control unit 91 outputs release information to release the unusable state to the device that owns the component when maintenance completion information is input from the input device 99 indicating that the component associated with the unusable information has been maintained. This management PC 90 allows the worker to input information that maintenance work has been performed, allowing proper maintenance to be performed. Furthermore, the mounting unit 20 includes components such as a negative pressure filter, the inside of the syringe, an O-ring inside the syringe, Q-axis gears 61 and 62, an O-ring inside the mechanical valve, the arm shaft 49 of the mechanical valve, the R-axis gear 52, the Z-axis ball screw 72, the Z-axis guide shaft, the cam follower 50 for driving the mechanical valve, and the prism glass surface of the side camera 48. These components are also subject to maintenance. With this mounting system 10, the usage status of these components can be monitored, making it easier to create maintenance plans.

It goes without saying that the management device and management method disclosed herein are in no way limited to the above-described embodiments, and can be implemented in various forms as long as they fall within the technical scope of the present disclosure.

For example, in the above-described embodiment, the unusable information is output to the mounting device 11 to block the use of the corresponding component , but if a list of maintenance items that are due for maintenance is displayed so that it is possible to visually check, the unusable state of the component may be omitted. The management PC 90 can grasp the usage status of the components that make up the mounting system 10, making it easier to create a maintenance plan.

Alternatively, in the above-described embodiment, which maintenance items are due for maintenance are displayed in a list format so that they can be visually confirmed, but this list display may be omitted if unusable information is output to the mounting device 11 and the use of the corresponding components is blocked. The management PC 90 disables components that are due for maintenance, so that appropriate maintenance can be performed.

In the above-described embodiment, when maintenance work is performed by the head maintenance device 80, release information is output to the management PC 90, but this may be omitted. The release information can be manually input by the operator via the operation panel 18, operation panel 88, or input device 99. Alternatively, in the above-described embodiment, the release information can be manually input by the operator, but this may be omitted. The release information can be automatically output from the head maintenance device 80.

In the above-described embodiment, the maintenance display screen 35 was used to display a list of multiple maintenance items, but it may also be possible to display a list of a single maintenance item. This maintenance display screen also allows users to understand the usage status of the components that make up the mounting system 10, making it easier to create maintenance plans.

In the above-described embodiment, the management PC 90 acquires usage information including operating time and number of operations, but it may acquire only one of these. Even with this management PC 90, it is possible to grasp the usage status of the components that make up the mounting system 10 and more easily create maintenance plans.

In the above-described embodiment, the components to be maintained are those listed in Figure 7, such as the negative pressure filter and O-ring, but this is not particularly limited to this, and one or more of these may be omitted, or components not listed here may be added. Also, in the above-described embodiment, the maintenance target is described as the mounting head 22, but this is not particularly limited to this, and other components may be maintained, such as the board processing unit 12, the component supply unit 14, the component imaging unit 16, and the operation panel 18. Also, while the mounting system 10 is described as including the head maintenance device 80, this may be omitted, or a maintenance device capable of maintaining components other than the mounting head 22 may be provided.

In the above-described embodiment, maintenance work includes cleaning, oiling, replacement, inspection (testing), etc., but is not limited to this; one or more of these may be omitted, or other work may be included.

In the above-described embodiment, the management device of the present disclosure was described as a management PC 90, but the functions of the management PC 90 may be provided in other devices, such as the mounting device 11 or the head maintenance device 80. In the above-described embodiment, the present disclosure was described as a management PC 90, but the present disclosure may also be a management method, or may also be a program executed by a computer.

The management device and management method disclosed herein can be used in devices related to the mounting process of placing components on a board.
