Description

This specification relates to a component mounting system that includes a component mounting machine.

The technology of mass-producing board products by performing substrate-related operations on boards on which circuit patterns are formed has become widespread. Furthermore, it has become common to arrange multiple substrate-related operation machines that perform substrate-related operations side by side and configure a production line in combination with a host computer for control. A component mounting machine, which is a typical example of a substrate-related operation machine, is equipped with replaceable peripheral devices such as a mounting head device that mounts components and a component supply device that supplies components. When a peripheral device is replaced during a changeover when changing the type of substrate product being produced, a preparatory operation is required. There are also cases where the preparatory operation is performed even if the peripheral device is not replaced. Examples of technology related to the preparatory operation of this type of component mounting machine are disclosed in Patent Documents 1 and 2.

In the component mounting device of Patent Document 1, first, the operation mode is switched to automatic by operating the input unit, and an automatic operation preparation operation is started. Specific items of the automatic operation preparation operation are the production data setting operation, the board confirmation operation, the conveyor width adjustment operation, and the suction nozzle confirmation operation. Then, when the automatic operation preparation operation is normally completed, the component mounting machine is started and production by automatic operation begins. In this automatic operation preparation operation, the module-specific status of the work module (component mounting machine) is compared with the automatic operation start conditions, and unnecessary preparation operations are excluded. It is said that this shortens the time required for the preparation operation and improves productivity.

In addition, in the substrate-related operation machine of Patent Document 2, the operation head (mounting head device) is provided with a recording medium that records its own unique value, and the unique information is read out, information related to the operation head is recognized based on the read unique information, and preparation processing for using the operation head is performed based on the recognized information. This is said to improve the convenience of the substrate-related operation machine, and in particular to enable automatic preparation processing of the operation head.

In the technical examples of Patent Documents 1 and 2, the preparatory operations before the component mounting machine starts the mounting operation are automated. Furthermore, in the technical example of Patent Document 1, the mounting operation starts automatically after the preparatory operations are completed. However, some component mounting machines allow the operator to command the start of the mounting operation, taking into consideration safety confirmation and final confirmation of the preparation status. In this case, the operator waits for the preparatory operations to be completed before commanding the start of the mounting operation, resulting in unnecessary waiting time. Furthermore, the operator experiences psychological stress while waiting.

The problem to be solved in this specification is to provide a component mounting system that eliminates the unnecessary waiting time of the operator and reduces psychological stress during the preparatory operations of the component mounting machine.

This specification discloses a component mounting system that includes a component mounting machine having a preparatory operation unit that performs preparatory operations after an operator has installed peripheral devices and establishes a start condition for mounting a component on a board, and a condition satisfaction notification unit that notifies a portable information device held by the operator that the start condition has been satisfied.

This specification also discloses a component mounting system that includes a component mounting machine having a preparatory operation unit that performs preparatory operations in response to instructions from an operator to establish a start condition for mounting a component on a board, and a condition establishment notification unit that notifies a portable information device held by the operator that the start condition has been established.

In the component mounting system disclosed in this specification, when the operator mounts a peripheral device or instructs the operator, the preparatory operation unit of the component mounting machine automatically performs the preparatory operation to establish the start conditions for the mounting work. In addition, the condition establishment notification unit notifies the portable information device that the start conditions have been established. Therefore, after mounting the peripheral device or instructing the preparatory operation, the operator can temporarily leave the component mounting machine to engage in another task. Then, when the portable information device is notified, the operator can return to the component mounting machine and instruct the start of the mounting work. Therefore, the operator does not need to wait beside the component mounting machine until the preparatory operation is completed, eliminating unnecessary waiting time and reducing psychological stress.

1. Configuration example of component mounting machine 1 First, a configuration example of the component mounting machine 1 included in the component mounting system 6 of the first embodiment will be described with reference to Fig. 1. In Fig. 1, the direction from the upper left to the lower right is the X-axis direction along which the board is transported, the direction from the lower left (rear side) to the upper right (front side) is the Y-axis direction, and the vertical direction is the Z-axis direction. The component mounting machine 1 repeatedly performs component mounting work. The component mounting machine 1 is configured by assembling a board transport unit 2, a component supply unit 3, a component transfer unit 4, a component camera 11, and a control unit 5 (see Fig. 2) on a base 10 and covered with a protective cover 12.

The board transport section 2 is composed of a first guide rail 21, a second guide rail 22, a pair of conveyor belts (not shown), and a clamp mechanism 23. The first guide rail 21 and the second guide rail 22 extend in the X-axis direction across the center of the top of the base 10 and are attached to the base 10 so as to be parallel to each other. A pair of conveyor belts are provided along the first guide rail 21 and the second guide rail 22. The pair of conveyor belts rotate with a board placed on the conveyor transport surface, and transport the board to and from the mounting position set in the center of the base 10. The clamp mechanism 23 is provided between the first guide rail 21 and the second guide rail 22. The clamp mechanism 23 pushes up the board that has been transported, clamps it in a horizontal position, and positions it at the mounting position.

The component supply unit 3 is removably mounted on the rear side of the component mounting machine 1. The component supply unit 3 is configured with a plurality of feeders 31 arranged on a pallet 35. The feeder 31 comprises a main body 32, a supply reel 33 provided on the rear side of the main body 32, and a supply position 34 provided at the top of the front end of the main body 32. A carrier tape containing a large number of components sealed at a predetermined pitch is wound and held on the supply reel 33. The feeder 31 performs a supply operation in which the carrier tape is sent out at a predetermined pitch by a tape drive mechanism (not shown), and the components are released from the sealed state and sequentially supplied to the supply position 34.

The feeder 31 is a form of a component supply device, and is also a form of a replaceable peripheral device. The supply reel 33 and the carrier tape are a form of component holder that holds multiple components. The feeder 31 stores its own device-specific information in a built-in non-volatile memory unit. In addition to an individual identification code, the feeder 31's unique information includes information on the supply reel 33 and the type of component, information on the position coordinates of the supply position 34, information on the operating characteristics of the tape drive mechanism, and information on the operation history and maintenance history. Note that a tray-type device or other type of device may be used as the component supply device.

The component transfer unit 4 is composed of a pair of Y-axis rails 41, a Y-axis moving table 42, a Y-axis motor 43, an X-axis moving table 44, an X-axis motor 45, and a mounting head device 46. The pair of Y-axis rails 41 are disposed from the front side of the base 10 to above the component supply unit 3 on the rear side. The Y-axis moving table 42 is mounted on the pair of Y-axis rails 41. The Y-axis moving table 42 is driven by the Y-axis motor 43 via a ball screw mechanism and moves in the Y-axis direction.

The X-axis moving stage 44 is mounted on the Y-axis moving stage 42. The X-axis moving stage 44 is driven by the X-axis motor 45 via a ball screw mechanism and moves in the X-axis direction. The mounting head device 46 is detachably attached to the rear side of the X-axis moving stage 44. The Y-axis rail 41, the Y-axis moving stage 42, the Y-axis motor 43, and the X-axis motor 45 constitute the head drive mechanism 40. The mounting head device 46 is driven by the head drive mechanism 40 to move in two horizontal directions.

The mounting head device 46 has a rotary tool 47 on the underside. The rotary tool 47 is rotated by an R-axis motor 48. Although omitted from FIG. 1, a number of suction nozzles are arranged in a ring shape on the underside of the rotary tool 47. The suction nozzles are rotated by a Q-axis motor (not shown). Furthermore, when the rotary tool 47 rotates, the suction nozzle located at the rearmost side is driven by a Z-axis motor (not shown) to move up and down. In addition to these operations, negative and positive pressures are supplied to the suction nozzles to perform the suction and mounting operations of the components.

The mounting head device 46 is one form of a replaceable peripheral device. The suction nozzle is one form of a component mounting tool. The mounting head device 46 stores unique information specific to the device itself in a built-in non-volatile memory unit. In addition to the individual identification code, the unique information of the mounting head device 46 includes information on the type and size of the suction nozzle, information on the position coordinates of the suction nozzle within the device, information on the operating characteristics of the R-axis motor 48, Z-axis motor, and Q-axis motor, and information on the operation history and maintenance history. Note that a clamp-type mounting tool or other type of mounting tool may be used as the component mounting tool.

The mark camera 49 is provided below the X-axis moving stage 44 and is arranged next to the rotary tool 47. The mark camera 49 and the head drive mechanism 40 operate during mounting work. The mark camera 49 captures an image of a position reference mark provided on the positioned board to detect the exact mounting position of the board.

The mark camera 49 and head drive mechanism 40 also operate during calibration operations. The mark camera 49 can capture an image of a position reference mark provided on the top surface of the base 10, etc., and perform a calibration operation of the X-Y coordinate system of the head drive mechanism 40. Furthermore, the mark camera 49 can capture an image of the supply position 34 of the feeder 31 and perform a calibration operation of the position coordinates of the supply position 34.

The component camera 11 is mounted facing upward on the top surface of the base 10 between the board transport unit 2 and the component supply unit 3. The component camera 11 operates during mounting work, capturing images of the multiple suction nozzles of the mounting head device 46 as they pick up components at the supply position 34 and move to the board. This allows the component camera 11 to capture images of the components held by the multiple suction nozzles all at once. The acquired image data is processed to confirm the presence or absence of components and whether they are correct, and to obtain the suction posture.

The component camera 11 also operates during calibration operations. The component camera 11 can capture an image of a position reference mark provided on the underside of the X-axis moving stage 44, etc., to perform a calibration operation of the X-Y coordinate system of the head drive mechanism 40. Furthermore, the component camera 11 can capture an image of the mounting head device 46 to perform a calibration operation of the position coordinates of the mounting head device 46 and the suction nozzle. In addition, a calibration operation can be performed by mutually photographing the component camera 11 and the mark camera 49.

The control unit 5 holds job data for each type of board product and controls the mounting work. The job data describes the detailed procedures and implementation methods of the mounting work. The control unit 5 sends various commands to the board transport unit 2, component supply unit 3, component transfer unit 4, and component camera 11, and receives information on the operating status. The control unit 5 may be configured as a single computer device, or may be configured with its functions distributed across multiple computer devices.

2. Functional configuration of component mounting system 6 of first embodiment Next, the functional configuration of component mounting system 6 of the first embodiment will be described with reference to Fig. 2. As shown in the figure, component mounting system 6 is composed of a component mounting machine 1 having a preparatory operation unit 53 and a progress display unit 54, and a condition satisfaction notification unit 93. Preparatory operation unit 53 and progress display unit 54 are realized by software of control unit 5. Condition satisfaction notification unit 93 is realized by software of host computer 9.

The component mounting machine 1 has an operation unit 51 and a display unit 52. The operation unit 51 accepts various commands from the operator, such as a command to perform preparatory operations and a command to start mounting work. The operation unit 51 is formed, for example, by a plurality of operation switches. The display unit 52 displays the contents of the operator's operations and the status of the component mounting machine 1. The display unit 52 is formed, for example, by a liquid crystal display device. The operation unit 51 and the display unit 52 are not limited to these, and may be a touch panel in which the two are integrated.

Upstream of the component mounting machine 1, a solder printing machine and a print inspection machine (not shown) are arranged side by side, and downstream of the component mounting machine 1, a board visual inspection machine and a reflow machine (not shown) are arranged side by side. A host computer 9 is provided to control these board-related work machines. This forms a production line for board products. The control unit 5 of the component mounting machine 1 is connected to the host computer 9 via wired communication, and controls the mounting work based on commands from the host computer 9. The control unit 5 also reports the progress of the mounting work, etc. to the host computer 9.

The host computer 9 has a wireless communication unit 91 that transmits information bidirectionally with a portable information device 8 held by an operator. Examples of the portable information device 8 include a dedicated wireless communication terminal and a general-purpose mobile phone (such as a smartphone). Examples of the wireless communication method include a dedicated in-house LAN communication and general-purpose Internet communication.

After the operator has installed the peripheral devices, the preparatory operation unit 53 automatically performs preparatory operations to establish the conditions for starting the mounting operation. For example, in a changeover when changing the type of board product being produced, the feeder 31 is replaced and installed to change the type of components to be mounted. Furthermore, the mounting head device 46 is replaced and installed in response to changes in the size or shape of the components. Also, for example, if the components supplied from the feeder 31 run out during the mounting operation, the feeder 31 is removed and another feeder 31 is installed.

The preparatory operations performed by the preparatory operation unit 53 include an information transfer operation and a calibration operation. More specifically, when the mounting head device 46 is installed, the preparatory operation unit 53 performs an information transfer operation to transfer the unique information of the mounting head device 46 from the storage unit to the control unit 5 on the main body side. This allows the control unit 5 to stably control the component suction operation and mounting operation, taking into account the unique characteristics and individual differences of each installed mounting head device 46.

Furthermore, the preparatory operation unit 53 performs a calibration operation regarding the position of the mounting head device 46. This calibration operation is performed using the mark camera 49 and the component camera 11. This compensates for any errors in the mounting position that may occur when the mounting head device 46 is mounted. Furthermore, the calibration operation eliminates the effects of individual differences in the mounting head device 46 and the rotary tool 47. Therefore, the control unit 5 can control the component suction and mounting operations with high precision.

When the feeder 31 is installed, the preparatory operation unit 53 performs an information transfer operation to transfer the unique information of the feeder 31 from the storage unit to the control unit 5 on the main body side. This allows the control unit 5 to stably control the part supply operation and suction operation, taking into account the unique characteristics and individual differences of each installed feeder 31.

Furthermore, the preparatory operation unit 53 performs a calibration operation regarding the component supply position 34 and the state of the carrier tape. This calibration operation is performed using the mark camera 49 and the component camera 11. This compensates for position errors in the supply position 34 that may occur when the feeder 31 is installed. Furthermore, the effects of individual differences and deformations in the carrier tape are eliminated by the calibration operation. Therefore, the control unit 5 can control the component supply operation and suction operation with high precision.

The preparatory operation unit 53 may perform only one of the above-mentioned information transfer operation and the calibration operation. The preparatory operation unit 53 may also perform preparatory operations other than those described above. Furthermore, when an operator commands a preparatory operation without installing a peripheral device, the preparatory operation unit 53 performs the above-mentioned calibration operation. For example, when the number of board products produced increases and there is concern about wear and tear on the peripheral devices, or when high reliability is required for the next type of board product to be produced, the operator commands a preparatory operation without replacing the peripheral devices.

The progress display unit 54 displays on the display unit 52 the progress of the preparatory operation performed by the preparatory operation unit 53. The progress display unit 54 acquires from the peripheral device an information transfer time estimated to be required for the information transfer operation of the preparatory operation. The peripheral device may store the information transfer time itself and pass it to the progress display unit 54. Alternatively, the peripheral device may pass the amount of information (data size) of the unique information stored therein, and the progress display unit 54 may refer to the information transfer specifications and estimate the information transfer time based on the amount of information.

In the prior art, the information transfer time was a fixed value for each type of peripheral device, and was set in the control unit 5. For this reason, every time a peripheral device was upgraded due to a design change, it was necessary to review and reset the fixed value (modify the software). Furthermore, there was a risk of incorrect settings.

In contrast, in the first embodiment, the progress display unit 54 obtains the information transfer time from the peripheral device. Therefore, the effort of resetting the information transfer time is unnecessary, and setting errors do not occur. In addition, it is possible to use an information transfer time that differs for each individual peripheral device and that can change over time. For example, when there is a large difference in the amount of unique information depending on the individual peripheral device, the information transfer time is estimated with high accuracy based on the amount of information for each individual device. In addition, when the amount of unique information increases over time, a large information transfer time corresponding to the amount of information is estimated, and therefore the accuracy of the information transfer time is maintained at a high level.

The progress display unit 54 can also estimate the time required for the current calibration operation with high accuracy based on the time required for previous calibration operations, etc. The calibration operation for the replaced peripheral device is performed using the new unique information acquired after the unique information transfer operation. The progress display unit 54 can estimate the total time required for the preparation operation based on the type, number, etc. of the replaced peripheral device.

Furthermore, the progress display unit 54 estimates the time required from the present time onwards that is estimated to be required for the preparatory action and displays it in real time. This allows the operator to check the displayed required time and decide on future actions. Note that the progress display unit 54 may use another display method, such as a method of displaying the progress as a percentage by dividing the time required from the present time onwards by the total required time.

When the preparatory operation is completed and the start condition is satisfied, the progress display unit 54 reports this to the condition satisfaction notification unit 93. The condition satisfaction notification unit 93 notifies the portable information device 8 held by the operator that the start condition has been satisfied. The progress display unit 54 also displays on the display unit 52 that the start condition has been satisfied.

3. Operation of the component mounting system 6 of the first embodiment Next, the operation of the component mounting system 6 of the first embodiment will be described with reference to the operation flow diagram of Fig. 3. In step S1 of Fig. 3, an operator installs a peripheral device or commands a preparatory operation. Step S1 serves as a start trigger for the preparatory operation unit 53. In the next step S2, the preparatory operation unit 53 performs a predetermined preparatory operation. After that, when a predetermined control cycle time has elapsed, the execution of the operation flow proceeds to step S3.

In step S3, the progress display unit 54 displays in real time the estimated time required from the present for the preparatory operation. The operator can look at this display and decide on future actions. For example, if the required time is short, the operator can stay near the component mounting machine 1, and if the required time is long, the operator can temporarily leave the component mounting machine 1 to engage in another task. Examples of another task include a task related to the setup of a different type of board product to be produced next by the component mounting machine 1, or a task related to a different production line.

In the next step S4, the progress display unit 54 determines whether the preparatory operation has ended and the start conditions for the mounting operation have been met. While the start conditions have not been met, steps S2 to S4 are repeatedly executed. Therefore, the operator can grasp the progress of the preparatory operation by checking the required time, which is successively updated in step S3 and gradually decreases. If the start conditions have been met in step S4, the execution of the operation flow proceeds to step S5.

In step S5, the condition satisfaction notification unit 93 notifies the portable information device 8 that the start condition has been satisfied. At the same time, the progress display unit 54 displays on the display unit 52 that the start condition has been satisfied. This ends the operation of the component mounting system 6. When the operator recognizes on the portable information device 8 that the start condition has been satisfied, he or she returns to the component mounting machine 1 and inputs a work start command for the mounting work from the operation unit 51. Alternatively, if the operator is near the component mounting machine 1, he or she may visually confirm that the start condition has been satisfied as displayed on the display unit 52 and input a work start command. In either case, the component mounting machine 1 starts the mounting work. Here, the operator can check the safety conditions inside and outside the component mounting machine 1 and make a final check of the preparation state of the component mounting machine 1 prior to the input operation.

In the component mounting system 6 of the first embodiment, when the operator installs a peripheral device or instructs the operator, the preparatory operation unit 53 of the component mounting machine 1 automatically performs the preparatory operation to establish the start condition for the mounting work. In addition, the condition establishment notification unit 93 notifies the portable information device 8 that the start condition has been established. Therefore, after installing the peripheral device or instructing the preparatory operation, the operator can temporarily leave the component mounting machine 1 to engage in another task. Then, when the portable information device 8 is notified, the operator can return to the component mounting machine 1 and instruct the start of the mounting work. Therefore, the operator does not need to wait beside the component mounting machine 1 until the preparatory operation is completed, which eliminates unnecessary waiting time and reduces psychological stress.

Furthermore, before the start of mounting work, the operator can check the safety situation and final confirmation of the preparation state. Therefore, the component mounting system 6 of the first embodiment is superior in terms of safety and reliability compared to the technology of Patent Document 1, which automatically starts mounting work after preparation operations are completed. In addition, the operator can check the required time, which gradually decreases, by looking at the display on the progress display unit 54, thereby significantly reducing psychological stress.

4. Functional Configuration and Operation of Component Mounting System 6A of Second Embodiment Next, the functional configuration and operation of component mounting system 6A of the second embodiment will be described with reference to Figures 4 and 5, focusing mainly on the differences from the first embodiment. As shown in the functional block diagram of Figure 4, in the second embodiment, a work initiation unit 55 is added to the control unit 5 of the component mounting machine 1. Furthermore, a reservation acquisition unit 92, a command acquisition unit 94, and a work start notification unit 95 are added to the host computer 9. Each of the added units is realized by software. The functions of each of the added units will be described next with reference to the operation flow diagram of Figure 5.

In step S11 of FIG. 5, the operator equips a peripheral device or commands a preparatory operation. Step S11 serves as a start trigger for the preparatory operation unit 53. In the next step S12, the operator inputs a notification reservation command to the portable information device 8. The reservation acquisition unit 92 acquires the input notification reservation command by wireless communication. The notification reservation command is a command to reserve a notification to the portable information device 8 of the establishment of the start condition. Here, input of the notification reservation command is an optional operation. For this reason, if the operator plans to visually confirm the establishment of the start condition displayed on the display unit 52, the execution of step S12 may be omitted.

In the next step S13, the preparatory operation unit 53 performs a predetermined preparatory operation. After this, when a predetermined control cycle time has elapsed, execution of the operation flow proceeds to step S14. In step S14, the progress display unit 54 displays in real time the estimated time required from the present for the preparatory operation. The operator can judge future actions by looking at this display.

In the next step S15, the progress display unit 54 determines whether the preparatory operation has ended and the start condition for the mounting operation has been met. While the start condition has not been met, steps S13 to S15 are repeatedly executed. If the start condition has been met in step S15, the execution of the operation flow proceeds to step S16. In step S16, the condition met notification unit 93 determines whether a notification reservation command has been acquired by the reservation acquisition unit 92.

In step S17, if a notification reservation command has been acquired, the condition satisfaction notification unit 93 notifies the portable information device 8 that the start condition has been satisfied. If a notification reservation command has not been acquired, the condition satisfaction notification unit 93 does not issue a notification, and execution of the operation flow branches to step S19. Note that regardless of whether a notification reservation command has been acquired or not, the progress display unit 54 displays on the display unit 52 that the start condition has been satisfied. The component mounting machine 1 is now in a state of waiting for a work start command.

When the operator recognizes on the portable information device 8 that the start condition is satisfied, in step S18, the operator inputs a work start command to the portable information device 8. The command acquisition unit 94 acquires the input work start command via wireless communication. Furthermore, the command acquisition unit 94 transfers the acquired work start command to the work start unit 55. Furthermore, when the operator visually recognizes that the start condition displayed on the display unit 52 is satisfied, in step S19, the operator inputs a work start command from the operation unit 51. In addition, when the operator recognizes on the portable information device 8 that the start condition is satisfied, the operator may execute step S19 (flow indicated by the dashed arrow in FIG. 5).

In the second embodiment, the work start command can be received either as a remote command via wireless communication or as an input operation to the operation unit 51. In either case, in step S20, the work start unit 55 starts the mounting work in accordance with the work start command. Furthermore, the work start unit 55 transfers work start information indicating that the mounting work has started to the work start notification unit 95. In the next step S21, the work start notification unit 95 notifies the portable information device 8 that the component mounting machine 1 has started the mounting work based on the transferred work start information. This ends the operation of the component mounting system 6A.

In the component mounting system 6A of the second embodiment, as in the first embodiment, unnecessary waiting time for the operator is eliminated and psychological stress is also reduced. Furthermore, the operator can start the mounting work of the component mounting machine 1 by a remote work start command via wireless communication without returning to the component mounting machine 1. Furthermore, even if the operator is away from the component mounting machine 1 or the host computer 9, the operator can confirm that the mounting work has started by the portable information device 8. In addition, flexible system operation is possible, such as optional operation of the notification reservation command and two ways of issuing the work start command.

5. Functional Configuration and Operation of Component Mounting System 6B of Third Embodiment Next, the functional configuration and operation of component mounting system 6B of the third embodiment will be described with reference to Fig. 6, focusing mainly on the differences from the first and second embodiments. As shown in the functional block diagram of Fig. 6, in the third embodiment, a camera 7 and an image transmission unit 96 are added to the configuration of the second embodiment. The camera 7 and the image transmission unit 96 operate regardless of the state of the component mounting machine 1 (stopped, in preparation, in mounting).

Camera 7 is disposed at least inside or around the exterior of component mounting machine 1. Camera 7 captures images of the safety conditions inside or around the exterior of component mounting machine 1, and at least one of the conditions at the start of mounting work, to obtain a situation image. Multiple cameras 7 may be provided. Camera 7 is preferably a video camera that captures moving images, but may also be a still image camera that captures still images at regular time intervals. Camera 7 transfers image data of the situation image to image transmission unit 96.

Examples of safety conditions captured by camera 7 include the presence or absence of foreign objects inside component mounting machine 1, the opening and closing status of protective cover 12, the remaining status of unused tools and carts, and the entry status of outsiders. Examples of conditions at the start of mounting work captured by camera 7 include the transport status of the board, the operating status of mounting head device 46, rotary tool 47, and suction nozzle, the lighting status when capturing images by mark camera 49 and component camera 11, the rotation status of supply reel 33, and the payout status of carrier tape. Note that camera 7 may capture conditions other than those mentioned above.

The image transmission unit 96 is realized by software of the host computer 9. The image transmission unit 96 transmits image data of the situation image captured by the camera 7 to the portable information device 8. The portable information device 8 has an image display function, and reproduces and displays the situation image captured by the camera 7.

In the component mounting system 6B of the third embodiment, the operator can check the safety conditions inside and outside the component mounting machine 1 by viewing the status image. Therefore, even when starting mounting work on the component mounting machine 1 by remote command, it is excellent in terms of safety. Furthermore, by viewing the status image, the operator can check the start status of mounting work on the component mounting machine 1 and the subsequent operating status. Therefore, even when starting mounting work on the component mounting machine 1 by remote command, it is excellent in terms of reliability.

6. Applications and Modifications of the Embodiments In the first embodiment, the progress display unit 54 may be omitted, and the operator may temporarily leave the component mounting machine 1. In the second and third embodiments, the reservation acquisition unit 92 may be omitted. In this modified embodiment, step S12 is omitted in the operation flow diagram of FIG. 5, and step S17 is unconditionally executed when the start condition is satisfied in step S15, and a work start command is acquired in step S18 or step S19. Furthermore, in the second and third embodiments, the work start notification unit 95 may be omitted. In this modified embodiment, step S21 is omitted in the operation flow diagram of FIG. 5.

In each embodiment, the progress display unit 54 may display the progress of the preparatory operation on the host computer 9 or the portable information device 8. Furthermore, in each embodiment, the component mounting system 6 may be configured not to include the host computer 9.
