[0012] In order to solve the above-mentioned problems, a component mounting device according to one embodiment of the present disclosure is a component mounting device that mounts components on a board, and includes: a detection unit for detecting a predetermined error during the operation of mounting the component on the board; an imaging unit that images the component mounted on the board; a control unit that, when the predetermined error is detected using the detection unit, controls the imaging unit to image the component mounted on the board at a position corresponding to the predetermined error; and a display unit that displays the image captured by the imaging unit.

[0013] This allows the imaging unit to be controlled to capture images of components mounted at positions on the board that correspond to a specified error, and prevents the imaging of components that are well mounted on the board and do not need to be captured, thereby preventing a decrease in production efficiency caused by the component mounting device.

[0014] In addition, a component mounting device according to one aspect of the present disclosure further includes a mounting unit having a drive unit, a lifting unit that is raised and lowered by the drive unit, and a holding unit that is supported on the lifting unit in a state where it can slide a predetermined distance in the vertical direction relative to the lifting unit and that adsorbs and holds the component, and the predetermined error may be an error caused by poor sliding of the holding unit relative to the lifting unit.

[0015] This allows efficient imaging of components mounted on a board using a holding section that has poor sliding contact with the lifting section, thereby further reducing a decrease in production efficiency due to the component mounting device.

[0016] In addition, a component mounting device according to one aspect of the present disclosure may further include a housing that houses the mounting unit with at least a portion of the holding portion exposed, and the imaging unit may move integrally with the housing.

[0017] This allows for easy imaging of components mounted on a board using a holding section that has poor sliding contact with the lifting section, thereby further reducing any decline in production efficiency due to the component mounting device.

[0018] Furthermore, the component mounting device according to one aspect of the present disclosure may further include an input unit that receives an input indicating that the board needs to be repaired or that the mounting operation can be continued.

[0019] This allows processing to be easily performed according to the state of component placement on the board, further reducing the decline in production efficiency due to the component placement device.

[0020] In addition, a component mounting device according to one aspect of the present disclosure may further include an update unit that, when the input unit receives input indicating that the board needs to be repaired, updates information regarding the mounting of the component mounted at a position on the board corresponding to the specified error from "mounting completed" to "mounting incomplete."

[0021] According to this, if the mounting state of the components on the board is poor and the board needs to be repaired, the information regarding the mounting of the components can be updated to indicate that mounting is incomplete, thereby preventing the board from being delivered with the components mounted on the board in a poor state.

[0022] In addition, in order to solve the above-mentioned problems, a display method according to one aspect of the present disclosure includes an imaging step of, when a predetermined error is detected during the operation of mounting a component on a board, imaging the component mounted on the board at a position corresponding to the predetermined error, and a display step of displaying the image captured in the imaging step.

[0023] This provides the same effects as the component mounting device described above.

[0024] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0025] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components that are not described in the independent claims that represent the highest concepts are described as optional components.

[0026] In addition, each drawing is a schematic diagram and is not necessarily an exact illustration. In addition, the same components are denoted by the same reference numerals in each drawing.

[0027] (Embodiment) 1 is a plan view showing a component mounting apparatus 10 according to an embodiment of the present invention. The configuration of the component mounting apparatus 10 will be described with reference to FIG.

[0028] 1, component mounting apparatus 10 includes a base 12, a transport unit 14, a pair of Y-axis tables 16, a pair of beams 18, a plurality of component supply units 20, a plurality of component mounting units 30, a plurality of board recognition cameras 22, a plurality of component recognition cameras 24, and an alarm unit 26. Component mounting apparatus 10 is an apparatus that mounts components 2 (see FIG. 3, etc.) onto board 1. For example, components 2 mounted on board 1 are electronic components.

[0029] The transport unit 14 is provided on the base 12 and transports the substrate 1. In this embodiment, the transport unit 14 transports the substrate 1 in the X-axis direction while positioning the substrate 1 in the Y-axis direction. The transport unit 14 has a pressure plate 14a. When the substrate 1 is positioned at a predetermined position, the substrate 1 is lifted upward and the side of the upper surface of the substrate 1 is pressed against the lower surface of the pressure plate 14a. In this way, the substrate 1 is held at a predetermined position. For example, the transport unit 14 is a conveyor.

[0030] Each of the pair of Y-axis tables 16 is attached to the base 12, and each of the pair of beams 18 is attached to the pair of Y-axis tables 16.

[0031] The multiple component supply units 20 are provided on both sides of the base 12, and each of the multiple component supply units 20 supplies components 2 to be mounted on the board 1. For example, each of the multiple component supply units 20 has multiple tape feeders, and supplies the components 2 by pitch-feeding a carrier tape holding the components 2.

[0032] Each of the multiple component mounting units 30 mounts a component 2 supplied from a corresponding one of the multiple component supply units 20 onto the board 1. Each of the multiple component mounting units 30 is attached to a beam 18. Each of the multiple component mounting units 30 moves in the Y-axis direction together with the beam 18 by a pair of Y-axis tables 16, and moves in the X-axis direction by the beam 18. Details of the component mounting units 30 will be described later.

[0033] Each of the plurality of board recognition cameras 22 is attached to a corresponding one of the plurality of component mounting units 30. Each of the plurality of board recognition cameras 22 is provided to capture an image below the corresponding one of the plurality of component mounting units 30, and captures an image of the board 1 from above in order to recognize the mounting positions of the components 2 on the board 1.

[0034] In this embodiment, the board recognition camera 22 is an example of an imaging unit that captures an image of the component 2 mounted on the board 1. The board recognition camera 22 is attached to the housing 32 of the component mounting unit 30, and moves integrally with the housing 32.

[0035] Each of the multiple component recognition cameras 24 captures an image of a component 2 held in a holder 52 (described later). In this embodiment, each of the multiple component recognition cameras 24 is provided between the conveying unit 14 and the component supply unit 20, and captures an image of the component 2 held in the holder 52 from below when the holder 52 passes between the conveying unit 14 and the component supply unit 20. Note that each of the multiple component recognition cameras 24 may be provided in a position where it can capture an image of the component 2 held in the holder 52.

[0036] The notification unit 26 notifies of an error. For example, the notification unit 26 has a display screen 27 (see FIG. 8), and notifies of an error by displaying error information indicating the error on the display screen 27.

[0037] In the present embodiment, the notification unit 26 is an example of a display unit that displays an image captured by the board recognition camera 22. For example, the notification unit 26 causes the display screen 27 to display the image captured by the board recognition camera 22.

[0038] In the present embodiment, notification unit 26 is an example of an input unit that receives an input indicating that board 1 needs to be repaired or that it is possible to continue the operation of mounting components 2 on board 1. For example, display screen 27 is a touch panel, and notification unit 26 receives an input when an icon on display screen 27 is touched.

[0039] The configuration of the component mounting apparatus 10 has been described above.

[0040] Fig. 2 is a front view showing the component mounting unit 30 of the component mounting device 10 of Fig. 1. Fig. 3 is a front view showing the holding unit 52 and other components of the component mounting unit 30 of Fig. 2. Note that Fig. 2 illustrates the housing 32 in cross section. Fig. 3 also illustrates a portion of the holding unit 52 in cross section. Details of the component mounting unit 30 will be described with reference to Figs. 2 and 3.

[0041] 2, the component mounting section 30 includes a housing 32 and multiple mounting units 34. The housing 32 houses a portion of each of the multiple mounting units 34. Specifically, the housing 32 houses the mounting units 34 with at least a portion of the holding section 52 exposed. Each of the multiple mounting units 34 includes a drive section 36, a lifting section 38, a support section 48, an elastic member 50, a holding section 52, and an elastic member 60.

[0042] The drive unit 36 ​​raises and lowers the lift unit 38. That is, the drive unit 36 ​​moves the lift unit 38 in the up and down direction. For example, the drive unit 36 ​​is a motor.

[0043] The lifting unit 38 is raised and lowered by the drive unit 36. The lifting unit 38 has a shaft 40 and a connecting unit 44. The shaft 40 extends in the vertical direction, is connected to the drive unit 36, and is moved in the vertical direction by the drive unit 36. The connecting unit 44 is connected to the lower end of the shaft 40, and connects the shaft 40 to the holding unit 52.

[0044] The support portion 48 slidably supports the shaft 40. For example, the support portion 48 is a spline guide. The elastic member 50 biases the shaft 40 upward. For example, the elastic member 50 is a return spring.

[0045] 3(a), the shaft 40 has a sliding shaft portion 42. The sliding shaft portion 42 extends in the vertical direction and is inserted into the holding portion 52, and the holding portion 52 is slidable along the sliding shaft portion 42.

[0046] The connecting portion 44 has an engagement hole 46. A pin 56 of the holding portion 52 is hooked into the engagement hole 46, whereby the holding portion 52 is supported by the lifting portion 38.

[0047] The holding unit 52 is supported by the lifting unit 38 in a state in which it can slide a predetermined distance in the vertical direction relative to the lifting unit 38, and sucks and holds the component 2. The holding unit 52 has a suction nozzle 54, a pin 56, and a sliding hole 58.

[0048] The suction nozzle 54 sucks and holds the component 2 at the lower end of the suction nozzle 54. The pin 56 is inserted into the engagement hole 46 and engages with the engagement hole 46 in a state where it can slide a predetermined distance in the vertical direction relative to the engagement hole 46. The sliding shaft 42 is inserted into the sliding hole 58 in a state where the sliding hole 58 and the sliding shaft 42 can slide relative to each other.

[0049] The elastic member 60 biases the connecting portion 44 and the holding portion 52 in directions separating them from each other. In other words, the elastic member 60 biases the holding portion 52 downward relative to the lifting portion 38. The elastic member 60 is, for example, a coil spring.

[0050] For example, as shown in Fig. 3(a), when the lifting / lowering unit 38 is moved downward by the driving unit 36 ​​while the component 2 is held by the suction nozzle 54, the component 2 held by the suction nozzle 54 comes into contact with the board 1, as shown in Fig. 3(b). When the lifting / lowering unit 38 is further moved downward by the driving unit 36 ​​from the state shown in Fig. 3(b), the lifting / lowering unit 38 slides downward relative to the holding unit 52, and the elastic member 60 contracts, urging the holding unit 52 downward, so that the component 2 held by the holding unit 52 can be pressed against the board 1 and attached, as shown in Fig. 3(c).

[0051] The component mounting section 30 has been described in detail above.

[0052] Fig. 4 is a block diagram showing the functional configuration of the component mounting apparatus 10 of Fig. 1. The functional configuration of the component mounting apparatus 10 will be described with reference to Fig. 4.

[0053] As shown in FIG. 4, each of the component mounting units 30 further includes a servo control unit 62 and a measurement unit 64.

[0054] The servo control unit 62 drives the drive unit 36 ​​and raises and lowers the lift unit 38 based on a command from the control unit 70. For example, the servo control unit 62 controls the position of the drive unit 36 ​​or the torque of the drive unit 36 ​​based on a command from the control unit 70.

[0055] The measuring unit 64 measures the thrust value of the driving unit 36 ​​when the driving unit 36 ​​lowers the holding unit 52 together with the lifting unit 38 and presses the component 2 held by the holding unit 52 against the board 1. For example, the measuring unit 64 measures the thrust value of the driving unit 36 ​​in the state shown in FIG. 3(c).

[0056] The measuring unit 64 measures the largest thrust value when the component 2 held by the holding unit 52 is pressed against the board 1. For example, the measuring unit 64 measures the thrust value of the driving unit 36 ​​when the lifting unit 38 is in the lowest position during mounting of the component 2 on the board 1.

[0057] The measuring section 64 measures the thrust value of the driving section 36 when the component 2 held by the holding section 52 is pressed against the board 1 in each of the multiple placement units 34 .

[0058] In this embodiment, measurement unit 64 is an example of a detection unit for detecting a predetermined error during the operation of placing component 2 on board 1. In this embodiment, the predetermined error is an error caused by a poor sliding state of holding unit 52 relative to lifting unit 38. As will be described in detail later, the sliding state of holding unit 52 relative to lifting unit 38 can be determined based on the thrust value of drive unit 36 ​​measured by measurement unit 64, and therefore measurement unit 64 can be used to detect an error caused by a poor sliding state of holding unit 52 relative to lifting unit 38.

[0059] The component mounting apparatus 10 further includes a control unit 70. When a predetermined error is detected using the measurement unit 64, the control unit 70 controls the board recognition camera 22 to capture an image of the component 2 mounted at a position on the board 1 that corresponds to the predetermined error. For example, when a predetermined error is detected during the operation of mounting the component 2 at a certain position on the board 1, the control unit 70 controls the board recognition camera 22 to capture an image of the component 2 mounted at that certain position.

[0060] Furthermore, in this embodiment, the control unit 70 is an example of an updating unit that updates information relating to the mounting of the component 2 mounted at a position on the substrate 1 corresponding to a predetermined error from "mounted" to "not mounted" when the notification unit 26 receives input indicating that the substrate 1 needs to be repaired. For example, the information relating to the mounting of the component 2 is information linked to the component 2, and is information indicating the mounting status of the component 2 on the substrate 1. For example, when the component 2 is not mounted on the substrate 1, the information relating to the mounting of the component 2 is "not mounted," and when the component 2 is mounted on the substrate 1, the information relating to the mounting of the component 2 is "mounted."

[0061] The control unit 70 includes an attachment processing unit 72, a determination unit 74, and a display processing unit 76.

[0062] The mounting processing unit 72 controls each unit of the component mounting device 10 to perform the component mounting work on the board 1 based on production data including the component names and mounting positions of the components 2 to be mounted on the board 1 .

[0063] The determination unit 74 determines the sliding state of the holding unit 52 relative to the lifting / lowering unit 38 based on the thrust value measured by the measurement unit 64. For example, the worse the sliding state of the holding unit 52 relative to the lifting / lowering unit 38, the greater the thrust value of the drive unit 36 ​​tends to be when the component 2 held by the holding unit 52 is pressed against the board 1. Therefore, the determination unit 74 can determine that the larger the thrust value measured by the measurement unit 64, the worse the sliding state of the holding unit 52 relative to the lifting / lowering unit 38.

[0064] The determining unit 74 determines whether the thrust value measured by the measuring unit 64 is equal to or greater than a predetermined threshold value, thereby determining the sliding state of the holding unit 52 relative to the lifting unit 38.

[0065] For example, the predetermined threshold is set in advance. For example, the predetermined threshold may be the maximum, minimum, or average value of the thrust value of the drive unit 36 ​​when the component 2 held by the holder 52 is pressed against the board 1 in a state where the sliding state of the holder 52 relative to the lifting unit 38 is so poor that the component 2 cannot be properly placed on the board 1. In this case, if the thrust value measured by the measurement unit 64 is equal to or greater than the predetermined threshold, the determination unit 74 can determine that the sliding state of the holder 52 relative to the lifting unit 38 is so poor that the component 2 cannot be properly placed on the board 1. On the other hand, if the thrust value measured by the measurement unit 64 is not equal to or greater than the predetermined threshold, the determination unit 74 can determine that the sliding state of the holder 52 relative to the lifting unit 38 is not so poor that the component 2 cannot be properly placed on the board 1.

[0066] The determining unit 74 determines the sliding state of the holding unit 52 relative to the lifting unit 38 in each of the multiple fitting units 34 .

[0067] The display processing unit 76 causes the notification unit 26 to notify various data measured by the measurement unit 64 and the like, and the determination results by the determination unit 74 and the like.

[0068] The notification unit 26 notifies of an error when the determination unit 74 determines that the thrust force value is equal to or greater than a predetermined threshold. For example, as described above, the notification unit 26 notifies of the error by displaying error information indicating the error on the display screen 27. Also, for example, the notification unit 26 displays an image captured by the board recognition camera 22 on the display screen 27.

[0069] The functional configuration of the component mounting apparatus 10 has been described above.

[0070] Fig. 5 is a flowchart showing a first operation example of the component mounting apparatus 10 of Fig. 1. Fig. 6 is a graph showing thrust values ​​measured by the measuring unit 64 of the component mounting apparatus 10 of Fig. 1. The first operation example of the component mounting apparatus 10 will be described with reference to Figs. 5 and 6.

[0071] 5, first, the component mounting unit 30 mounts the component 2 on the board 1 (step S1). Specifically, as shown in (a) to (c) of FIG. 3, the drive unit 36 ​​moves the holding unit 52 downward together with the lifting unit 38, and the component 2 held by the holding unit 52 is pressed against the board 1, thereby mounting the component 2 on the board 1.

[0072] The measuring unit 64 measures the thrust value of the driving unit 36 ​​when the component 2 is mounted on the board 1 (measurement step) (step S2). For example, as described above, the measuring unit 64 measures the thrust value of the driving unit 36 ​​when the driving unit 36 ​​lowers the holding unit 52 together with the lifting unit 38 and the component 2 held by the holding unit 52 is pressed against the board 1. Also, for example, as described above, the measuring unit 64 measures the largest thrust value when the component 2 held by the holding unit 52 is pressed against the board 1.

[0073] 6(a), when component 2 held by holder 52 is not pressed against board 1 and suction nozzle 54 is being lowered, the thrust value of drive unit 36 ​​is constant. When component 2 held by holder 52 is pressed against board 1 and attached to board 1, the thrust value of drive unit 36 ​​increases. When suction nozzle 54 is being raised after component 2 has been attached to board 1, the thrust value of drive unit 36 ​​decreases when suction nozzle 54 is in contact with component 2, and remains constant when suction nozzle 54 is away from component 2.

[0074] As shown in FIG. 5, when the measurement unit 64 measures the thrust value, the determination unit 74 determines whether the thrust value is equal to or greater than a predetermined threshold (determination step) (step S3). In this manner, the determination unit 74 determines the sliding state of the holding unit 52 relative to the lifting unit 38 by determining whether the thrust value is equal to or greater than the predetermined threshold. For example, as shown in FIG. 6(a), if the measurement unit 64 does not measure a thrust value equal to or greater than the predetermined threshold, the determination unit 74 determines that the measured thrust value is not equal to or greater than the predetermined threshold. On the other hand, for example, as shown in FIG. 6(b), if the measurement unit 64 measures a thrust value equal to or greater than the predetermined threshold, the determination unit 74 determines that the measured thrust value is equal to or greater than the predetermined threshold.

[0075] As shown in FIG. 5, when the determining unit 74 determines that the thrust value is equal to or greater than a predetermined threshold value (Yes in step S3), the notifying unit 26 notifies of an error (step S4).

[0076] When the notification unit 26 notifies of the error, the component mounting apparatus 10 stops production (step S5). Specifically, the component mounting apparatus 10 stops mounting the components 2 onto the board 1.

[0077] When the component mounting device 10 stops production, the notification unit 26 displays a cleaning instruction (step S6). For example, the notification unit 26 displays the cleaning instruction on the display screen 27.

[0078] When the notification unit 26 displays the cleaning instruction, the user cleans the component mounting device 10 (step S7). Specifically, the user cleans the part of the component mounting device 10 that is causing the poor sliding state of the holding unit 52 relative to the lifting unit 38.

[0079] When the user cleans the component mounting apparatus 10, the component mounting apparatus 10 resumes production (step S8). Specifically, the component mounting apparatus 10 resumes mounting of the components 2 onto the board 1.

[0080] If the determination unit 74 determines that the thrust value is not equal to or greater than the predetermined threshold value (No in step S3), and if the component mounting device 10 resumes production (step S8), the determination unit 74 determines whether or not there is a next component 2 (step S9). Specifically, the determination unit 74 determines whether or not there is still a component 2 to be mounted on the board 1.

[0081] If the determining unit 74 determines that there is a next component 2 (Yes in step S9), the component mounting unit 30 mounts a component 2 on the board 1 again (step S1).

[0082] If the determining unit 74 determines that there is no next component 2 (No in step S9), the component mounting device 10 ends the process.

[0083] The first operation example of the component mounting apparatus 10 has been described above.

[0084] Fig. 7 is a flowchart showing a second operation example of the component mounting apparatus 10 of Fig. 1. Fig. 8 is a diagram showing an image captured by the board recognition camera 22 of the component mounting apparatus 10 of Fig. 1. The second operation example of the component mounting apparatus 10 will be described with reference to Figs. 7 and 8.

[0085] Operation Example 2 differs from Operation Example 1 mainly in that it further performs the processes of steps S10 to S14. The following description will focus on the differences from Operation Example 1.

[0086] 7, when the user cleans the component mounting device 10 (step S7), the board recognition camera 22 captures an image of the component 2 mounted at a position on the board 1 that corresponds to the predetermined error (imaging step) (step S10). In this way, when a predetermined error is detected during the operation of mounting the component 2 on the board 1, the board recognition camera 22 captures an image of the component 2 mounted at a position on the board 1 that corresponds to the predetermined error.

[0087] When the board recognition camera 22 captures an image of the component 2 mounted at a position on the board 1 that corresponds to a predetermined error, the notification unit 26 displays the image captured by the board recognition camera 22 (display step) (step S11). For example, as shown in Fig. 8, the notification unit 26 displays the image 100 captured by the board recognition camera 22.

[0088] 7, when the image is displayed by the notification unit 26, the notification unit 26 accepts input from the worker (step S12). For example, as shown in Fig. 8, the notification unit 26 displays a "repair" icon to accept input that the board 1 needs to be repaired, and displays a "continue" icon to accept input that the operation of mounting the components 2 on the board 1 can be continued. In this way, for example, the notification unit 26 accepts input that the board 1 needs to be repaired or that the mounting operation can be continued.

[0089] 7, when the notification unit 26 receives an input from the worker, the determination unit 74 determines whether or not an input indicating that the board 1 needs to be repaired has been received (step S13). For example, as shown in FIG. 8, when the "repair" icon is touched, the determination unit 74 determines that an input indicating that the board 1 needs to be repaired has been received.

[0090] As shown in FIG. 7, if the judgment unit 74 judges that input indicating that the board 1 needs to be repaired has been received (Yes in step S13), the control unit 70 updates the information regarding the mounting of the component 2 mounted at the position corresponding to the specified error on the board 1 from "mounted" to "mounted incomplete" (step S14).

[0091] When the control unit 70 updates the information regarding the placement of the components 2 from "placement completed" to "placement incomplete," the component placement device 10 resumes production (step S8).

[0092] If the determining unit 74 determines that an input indicating that the board 1 needs to be repaired has not been received (No in step S13), the determining unit 74 determines whether or not there is a next component 2 (step S9).

[0093] The second operation example of the component mounting apparatus 10 has been described above.

[0094] As described above, the component mounting apparatus 10 can determine the sliding state of the holding unit 52 relative to the lifting unit 38. This makes it easier to clean the component mounting apparatus 10 at an appropriate time, and prevents a decrease in production efficiency using the component mounting apparatus 10. Furthermore, since there is no need to provide a separate measuring device for measuring load, an increase in the installation space and costs for the component mounting apparatus 10 can be prevented.

[0095] Furthermore, the component mounting apparatus 10 can capture an image of the component 2 that has been mounted at a position corresponding to a predetermined error on the board 1. This makes it possible to prevent a decrease in production efficiency by the component mounting apparatus 10.

[0096] The component mounting apparatus 10 according to the embodiment has been described above.

[0097] The component mounting device 10 according to the embodiment is a component mounting device that mounts a component 2 on a board 1, and includes a measurement unit 64 for detecting a predetermined error during the mounting operation of the component 2 on the board 1, a board recognition camera 22 that captures an image of the component 2 mounted on the board 1, a control unit 70 that, when a predetermined error is detected using the measurement unit 64, controls the board recognition camera 22 to capture an image of the component 2 mounted at a position on the board 1 that corresponds to the predetermined error, and an alarm unit 26 that displays the image captured by the board recognition camera 22.

[0098] This allows the board recognition camera 22 to be controlled to capture an image of the component 2 mounted at a position on the board 1 that corresponds to a specified error, and prevents the capturing of images of components that do not need to be captured because the component 2 is well mounted on the board 1, thereby preventing a decrease in production efficiency by the component mounting device 10.

[0099] In addition, the component mounting device 10 according to the embodiment further includes a mounting unit 34 having a drive unit 36, a lifting unit 38 that is raised and lowered by the drive unit 36, and a holding unit 52 that is supported by the lifting unit 38 in a state where it can slide a predetermined distance in the vertical direction relative to the lifting unit 38 and that adsorbs and holds the component 2, and the specified error is an error caused by poor sliding of the holding unit 52 relative to the lifting unit 38.

[0100] This allows efficient imaging of components 2 mounted on board 1 using holder 52 that is not in a good sliding state with respect to lifting section 38, thereby further preventing a decrease in production efficiency by component mounting apparatus 10.

[0101] In addition, the component mounting device 10 according to the embodiment further includes a housing 32 that houses the mounting unit 34 with at least a portion of the holding portion 52 exposed, and the board recognition camera 22 moves integrally with the housing 32.

[0102] This allows for easy imaging of components 2 mounted on board 1 using holder 52 that is not in a good sliding state with respect to lifting section 38, thereby further reducing a decrease in production efficiency of component mounting apparatus 10.

[0103] Moreover, the component mounting apparatus 10 according to the embodiment further includes a notification unit 26 that receives an input indicating that the board 1 needs to be repaired or that the mounting operation can be continued.

[0104] This allows processing to be easily performed according to the mounting state of the components 2 on the board 1, and therefore reduces or prevents a decrease in production efficiency by the component mounting apparatus 10.

[0105] In addition, the component mounting device 10 according to the embodiment further includes a control unit 70 that, when the notification unit 26 receives input indicating that the board 1 needs to be repaired, updates information regarding the mounting of the component 2 mounted at a position on the board 1 corresponding to a specified error from mounting complete to mounting incomplete.

[0106] According to this, if the mounting state of the component 2 on the board 1 is poor and the board 1 needs to be repaired, the information regarding the mounting of the component 2 can be updated to indicate that mounting is incomplete, thereby preventing the board 1 from being delivered with the component 2 mounted on the board 1 in a poor state.

[0107] In addition, the display method of the embodiment includes an imaging step of imaging the component 2 mounted at a position on the board 1 corresponding to the specified error when a specified error is detected during the mounting operation of the component 2 on the board 1, and a display step of displaying the image captured in the imaging step.

[0108] This provides the same effects as the component mounting apparatus 10 described above.

[0109] (Other embodiments, etc.) While the component mounting apparatus and the like according to one or more aspects have been described above based on the embodiments, the present disclosure is not limited to these embodiments. As long as they do not deviate from the spirit of the present disclosure, various modifications conceivable by those skilled in the art may also be included within the scope of the present disclosure.

[0110] In the above-described embodiment, the component mounting apparatus 10 is described as having a plurality of component supply units 20, a plurality of component mounting units 30, a plurality of board recognition cameras 22, and a plurality of component recognition cameras 24. However, the present invention is not limited to this. For example, the component mounting apparatus 10 may have only one component supply unit 20, one component mounting unit 30, one board recognition camera 22, and one component recognition camera 24, rather than multiple components.

[0111] In the above-described embodiment, the component mounting unit 30 has been described as having a plurality of mounting units 34. However, the present invention is not limited to this. For example, the component mounting unit 30 may have a single mounting unit 34 instead of a plurality of mounting units 34.

[0112] Furthermore, in the above-described embodiment, the predetermined error is an error caused by a poor sliding state of the holding unit 52 relative to the lifting unit 38, but this is not limiting. For example, the predetermined error may be an error caused by an abnormality in the flow rate of air blown toward the component 2 when the component 2 is mounted on the board 1. In this case, for example, the detection unit may be a measuring device or the like that measures the flow rate of the air.

[0113] In the above-described embodiments, each component may be configured with dedicated hardware, or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU (Central Processing Unit) or processor reading and executing a software program recorded on a recording medium such as a hard disk or semiconductor memory. Here, the software that realizes the devices and the like of the above-described embodiments is a program that causes a computer to execute each step included in the flowcharts shown in Figures 5 and 7.
