Description

This disclosure relates to a component mounting device and a display method.

Component mounting devices that mount components on a circuit board are known in the past. As an example of a component mounting device, Patent Document 1 discloses a component mounting system that includes a component mounting unit that mounts components on a circuit board and an inspection unit that takes images of the components mounted on the circuit board. The inspection unit determines whether the components are properly mounted on the circuit board based on the obtained images.

JP 2011-82376 A

However, the component mounting system of Patent Document 1 also takes images of components that are well mounted and do not require imaging, which reduces the production efficiency of the component mounting system.

This disclosure therefore provides a component mounting device that can prevent a decrease in production efficiency caused by the component mounting device.

A component mounting device according to one aspect of the present disclosure is a component mounting device that mounts components onto a board, and includes a detection unit for detecting a predetermined error during the operation of mounting the component onto the board, an imaging unit that captures an image of 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 capture an image of 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.

Furthermore, a display method according to one aspect of the present disclosure includes, when a predetermined error is detected during the operation of mounting a component on a board, an imaging step of 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.

Note that these comprehensive or specific aspects may be realized as a system, method, integrated circuit, computer program, or computer-readable recording medium such as a CD-ROM, or as any combination of a system, method, integrated circuit, computer program, and recording medium. The recording medium may also be a non-transitory recording medium.

The component mounting device and the like disclosed herein can prevent a decrease in production efficiency caused by the component mounting device.

Further advantages and benefits of one aspect of the present disclosure will become apparent from the specification and drawings. While such advantages and/or benefits may be provided by some of the embodiments and features described in the specification and drawings, not all of them necessarily need to be provided in order to obtain one or more identical features.

FIG. 2 is a front view showing the component mounting section of the component mounting apparatus of FIG. 3 is a front view showing the holding portion and the like of the component mounting portion of FIG. 2. FIG. FIG. 4 is a block diagram showing the functional configuration of the component mounting apparatus of FIG.

FIG. 7 is a flowchart showing a second example of the operation of the component mounting apparatus of FIG. FIG. 8 is a diagram showing an image captured by the board recognition camera of the component mounting apparatus of FIG.

In order to solve the above-mentioned problems, a component mounting device according to one aspect 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 captures an image of 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 capture an image of 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.

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

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 by 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.

This allows for efficient imaging of components mounted on a board using a holding unit that has poor sliding contact with the lifting unit, further reducing any decline in production efficiency caused by the component mounting device.

Furthermore, 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 section exposed, and the imaging section may move integrally with the housing.

This makes it easy to capture images of components mounted on a board using a holding unit that has poor sliding contact with the lifting unit, further reducing declines in production efficiency caused by the component mounting device.

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

This allows for easy processing according to the mounting state of components on the board, further minimizing declines in production efficiency due to the component mounting device.

Furthermore, 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 the position on the board corresponding to the specified error from "mounted" to "not mounted."

This means that if the mounting of components on a board is poor and the board needs to be repaired, the information about the mounting of the components can be updated to indicate that mounting is incomplete, thereby preventing boards from being delivered with components not properly mounted.

In order to solve the above-mentioned problems, a display method according to one aspect of the present disclosure includes, when a predetermined error is detected during the operation of mounting a component on a board, an imaging step of 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.

This provides the same benefits as the component mounting device described above.

The following describes the embodiments in detail, with reference to the drawings.

Furthermore, among the components in the following embodiments, components that are not recited in an independent claim that represents a superordinate concept are described as optional components.

Furthermore, each figure is a schematic diagram and is not necessarily an exact representation. Furthermore, the same components are designated by the same reference numerals in each figure.

(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.

As shown in FIG. 1, the component mounting device 10 includes a base 12, a transport unit 14, a pair of Y-axis tables 16, a pair of beams 18, multiple component supply units 20, multiple component mounting units 30, multiple board recognition cameras 22, multiple component recognition cameras 24, and a notification unit 26. The component mounting device 10 is a device that mounts components 2 (see FIG. 3, etc.) onto a board 1. For example, the components 2 mounted on the board 1 are electronic components.

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 in a predetermined position. For example, the transport unit 14 is a conveyor.

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.

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 components 2 by pitch-feeding a carrier tape holding the components 2.

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.

Each of the multiple board recognition cameras 22 is attached to a corresponding one of the multiple component mounting units 30. Each of the multiple board recognition cameras 22 is configured to capture an image below the corresponding one of the multiple 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.

In this embodiment, the board recognition camera 22 is an example of an imaging unit that captures images of the components 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.

Each of the multiple component recognition cameras 24 captures an image of a component 2 held in a holding unit 52 (described below). 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 holding unit 52 from below as the holding unit 52 passes between the conveying unit 14 and the component supply unit 20. Note that each of the multiple component recognition cameras 24 only needs to be provided in a position where it can capture an image of the component 2 held in the holding unit 52.

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.

In this 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 displays the image captured by the board recognition camera 22 on the display screen 27.

In addition, in this embodiment, the notification unit 26 is an example of an input unit that accepts input that the board 1 needs to be repaired or that the operation of mounting the component 2 on the board 1 can continue. For example, the display screen 27 is a touch panel, and the notification unit 26 accepts input when an icon on the display screen 27 is touched.

The configuration of the component mounting device 10 has been described above.

Figure 2 is a front view showing the component mounting unit 30 of the component mounting device 10 of Figure 1. Figure 3 is a front view showing the holding unit 52 and other components of the component mounting unit 30 of Figure 2. Note that Figure 2 illustrates the housing 32 in cross section. Figure 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 Figures 2 and 3.

As shown in FIG. 2, the component mounting section 30 has 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 has 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.

The drive unit 36 raises and lowers the lifting unit 38. In other words, the drive unit 36 moves the lifting unit 38 in the up and down direction. For example, the drive unit 36 is a motor.

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 vertically and is connected to the drive unit 36, causing it to move vertically 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.

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.

As shown in Figure 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, which can slide along the sliding shaft portion 42.

The connecting portion 44 has an engagement hole 46. The pin 56 of the holding portion 52 is hooked into the engagement hole 46, thereby supporting the holding portion 52 on the lifting portion 38.

The holding unit 52 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 it picks up and holds the component 2. The holding unit 52 has a suction nozzle 54, a pin 56, and a sliding hole 58.

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.

The elastic member 60 biases the connecting portion 44 and the holding portion 52 in directions that move them away from each other. In other words, the elastic member 60 biases the holding portion 52 downward relative to the lifting portion 38. For example, the elastic member 60 is a coil spring.

For example, as shown in FIG. 3(a), when the lifting unit 38 is moved downward by the drive unit 36 while a 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). If the lifting unit 38 is further moved downward by the drive unit 36 from the state shown in FIG. 3(b), the lifting unit 38 slides downward relative to the holding unit 52, as shown in FIG. 3(c), 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.

The above explains the details of the component mounting unit 30.

Figure 4 is a block diagram showing the functional configuration of the component mounting device 10 in Figure 1. The functional configuration of the component mounting device 10 will be described with reference to Figure 4.

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

The servo control unit 62 drives the drive unit 36 and raises and lowers the lift unit 38 based on commands 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 commands from the control unit 70.

The measurement unit 64 measures the thrust value of the drive unit 36 when the drive 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 measurement unit 64 measures the thrust value of the drive unit 36 in the state shown in Figure 3(c).

The measuring unit 64 measures the greatest 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 its lowest position during mounting of the component 2 on the board 1.

The measurement unit 64 measures the thrust value of the drive unit 36 when the component 2 held by the holding unit 52 in each of the multiple mounting units 34 is pressed against the board 1.

In this embodiment, the measurement unit 64 is an example of a detection unit for detecting a predetermined error during the operation of mounting the component 2 on the board 1. In this embodiment, the predetermined error is an error caused by a poor sliding condition of the holding unit 52 relative to the lifting unit 38. As will be described in detail below, the sliding condition of the holding unit 52 relative to the lifting unit 38 can be determined based on the thrust value of the drive unit 36 measured by the measurement unit 64, and therefore, an error caused by a poor sliding condition of the holding unit 52 relative to the lifting unit 38 can be detected using the measurement unit 64.

The component mounting device 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 a 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.

In addition, in this embodiment, the control unit 70 is an example of an update unit that updates information related to the mounting of a component 2 mounted at a position on the board 1 corresponding to a specified error from "mounted" to "mounted incomplete" when the notification unit 26 receives input indicating that the board 1 needs to be repaired. For example, information related to the mounting of component 2 is information linked to component 2 and indicates the mounting status of component 2 on the board 1. For example, if component 2 is not mounted on the board 1, the information related to the mounting of that component 2 is "mounted incomplete," and if component 2 is mounted on the board 1, the information related to the mounting of that component 2 is "mounted incomplete."

The control unit 70 has an attachment processing unit 72, a determination unit 74, and a display processing unit 76.

The mounting processing unit 72 controls each part of the component mounting device 10 to perform component mounting work on the board 1 based on production data including the component name and mounting position of the component 2 to be mounted on the board 1.

The determination unit 74 determines the sliding condition 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 condition 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 greater the thrust value measured by the measurement unit 64, the worse the sliding condition of the holding unit 52 relative to the lifting/lowering unit 38.

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 measured by the measurement unit 64 is equal to or greater than a predetermined threshold.

For example, the predetermined threshold is determined in advance. For example, the predetermined threshold is the maximum, minimum, or average value of the thrust force 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 condition of the holder 52 relative to the lifting unit 38 is so poor that the component 2 cannot be properly mounted 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 condition of the holder 52 relative to the lifting unit 38 is so poor that the component 2 cannot be properly mounted 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 condition of the holder 52 relative to the lifting unit 38 is not so poor that the component 2 cannot be properly mounted on the board 1.

The determination unit 74 determines the sliding state of the holding unit 52 relative to the lifting unit 38 for each of the multiple mounting units 34.

The display processing unit 76 causes the notification unit 26 to notify various data measured by the measurement unit 64, etc., and the judgment results by the judgment unit 74, etc.

The notification unit 26 notifies of an error when the determination unit 74 determines that the thrust value is equal to or greater than a predetermined threshold. For example, as described above, the notification unit 26 notifies of an 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.

The functional configuration of the component mounting device 10 has been described above.

Figure 5 is a flowchart showing operation example 1 of the component mounting device 10 of Figure 1. Figure 6 is a graph showing thrust values measured by the measurement unit 64 of the component mounting device 10 of Figure 1. Operation example 1 of the component mounting device 10 will be described with reference to Figures 5 and 6.

As shown in FIG. 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.

The measurement unit 64 measures the thrust value of the drive unit 36 when the component 2 is mounted on the board 1 (measurement step) (step S2). For example, as described above, the measurement unit 64 measures the thrust value of the drive unit 36 when the drive 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 measurement 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, as shown in Figure 6(a), when the component 2 held by the holder 52 is not pressed against the board 1 and the suction nozzle 54 is being lowered, the thrust value of the drive unit 36 is constant. When the component 2 held by the holder 52 is pressed against the board 1 and attached to the board 1, the thrust value of the drive unit 36 increases. When the suction nozzle 54 is raised after the attachment of the component 2 to the board 1 is complete, the thrust value of the drive unit 36 decreases when the suction nozzle 54 is in contact with the component 2, and the thrust value of the drive unit 36 is constant when the suction nozzle 54 is away from the component 2.

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). Thus, here, 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.

As shown in FIG. 5, if the determination unit 74 determines that the thrust value is equal to or greater than a predetermined threshold (Yes in step S3), the notification unit 26 notifies an error (step S4).

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

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.

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

Once the user has cleaned the component mounting device 10, the component mounting device 10 resumes production (step S8). Specifically, the component mounting device 10 resumes mounting components 2 onto the board 1.

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), or if the component mounting device 10 resumes production (step S8), the determination unit 74 determines whether there is a next component 2 (step S9). Specifically, the determination unit 74 determines whether there are any more components 2 to be mounted on the board 1.

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

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

The above describes operation example 1 of the component mounting device 10.

Figure 7 is a flowchart showing a second operational example of the component mounting device 10 of Figure 1. Figure 8 is a diagram showing an image captured by the board recognition camera 22 of the component mounting device 10 of Figure 1. Operational example 2 of the component mounting device 10 will be described with reference to Figures 7 and 8.

Operation Example 2 differs from Operation Example 1 primarily in that it further performs steps S10 to S14. The following explanation will focus on the differences from Operation Example 1.

As shown in FIG. 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 specified error (imaging step) (step S10). In this way, if a specified error is detected during the mounting operation of 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 specified error.

When the board recognition camera 22 captures an image of a 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 an image 100 captured by the board recognition camera 22.

As shown in FIG. 7, once 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 component 2 onto 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.

As shown in FIG. 7, when the notification unit 26 receives input from the worker, the determination unit 74 determines whether input indicating that the board 1 needs repair has been received (step S13). For example, as shown in FIG. 8, when the "repair" icon is touched, the determination unit 74 determines that input indicating that the board 1 needs repair has been received.

As shown in FIG. 7, if the determination unit 74 determines 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 on the board 1 corresponding to the specified error from "mounted" to "mounted incomplete" (step S14).

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

If the determination unit 74 determines that input indicating that the board 1 needs to be repaired has not been received (No in step S13), the determination unit 74 determines whether the next component 2 is present (step S9).

The above describes operation example 2 of the component mounting device 10.

As described above, the component mounting device 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 device 10 at the appropriate time, preventing a decrease in production efficiency using the component mounting device 10. Furthermore, since there is no need to install a separate measuring device to measure load, an increase in the installation space and costs of the component mounting device 10 can be prevented.

In addition, the component mounting device 10 can capture images of components 2 mounted at positions on the board 1 that correspond to specified errors. This helps prevent a decline in production efficiency using the component mounting device 10.

The above describes the component mounting device 10 according to the embodiment.

The component mounting device 10 according to the embodiment is a component mounting device that mounts components 2 on a board 1, and includes a measurement unit 64 for detecting a predetermined error during the operation of mounting the components 2 on the board 1, a board recognition camera 22 that captures an image of the components 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 a notification unit 26 that displays the image captured by the board recognition camera 22.

This allows the board recognition camera 22 to be controlled to capture images of components 2 mounted at positions on the board 1 that correspond to a specified error, and prevents the capturing of images of components that are well mounted on the board 1 and do not need to be captured, thereby preventing a decrease in production efficiency by the component mounting device 10.

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; the predetermined error is an error caused by poor sliding of the holding unit 52 relative to the lifting unit 38.

This allows for efficient imaging of components 2 mounted on the board 1 using a holding unit 52 that has poor sliding contact with the lifting unit 38, further reducing any decline in production efficiency caused by the component mounting device 10.

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.

This allows for easy imaging of components 2 mounted on the board 1 using a holding unit 52 that has poor sliding contact with the lifting unit 38, further reducing any decline in production efficiency caused by the component mounting device 10.

In addition, the component mounting device 10 according to the embodiment further includes a notification unit 26 that accepts input indicating that the board 1 needs to be repaired or that the mounting operation can continue.

This allows processing to be easily performed according to the mounting state of the component 2 on the board 1, further reducing any decline in production efficiency caused by the component mounting device 10.

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 repair, updates the mounting information for the component 2 mounted at the position on the board 1 corresponding to a specified error from "mounting complete" to "mounting incomplete."

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

Furthermore, the display method according to the embodiment includes an imaging step of imaging the component 2 mounted on the board 1 at a position 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.

This provides the same effects as the component mounting device 10 described above.

(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.

In the above-described embodiment, the component mounting device 10 is described as having multiple component supply units 20, multiple component mounting units 30, multiple board recognition cameras 22, and multiple component recognition cameras 24, but this is not limited to this. For example, the component mounting device 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 cameras.

Furthermore, in the above-described embodiment, the component mounting unit 30 has been described as having multiple mounting units 34, but this is not limited to this. For example, the component mounting unit 30 may have only one mounting unit 34 instead of multiple mounting units.

In addition, in the above-described embodiment, the specified error is an error caused by poor sliding of the holding unit 52 relative to the lifting unit 38, but this is not limited to this. For example, the specified 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, the detection unit may be, for example, a measuring device that measures the flow rate of the air.

In the above-described embodiments, each component may be configured with dedicated hardware, or may be realized by executing a software program appropriate for that 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, etc. 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.

This disclosure can be used in devices for mounting components on substrates, etc.
