- FIG. 1 is a schematic diagram of a component mounting apparatus in the present embodiment.
- the component mounting apparatus is an example of a positioning system that determines a relative position between a predetermined target and some configuration.
- a Y beam 105 operating in the Y-axis direction in the drawing is driven and positioned in the Y-axis direction by two Y linear motors 101 and 103.
- the mounting head 108 which is an example of a working unit, is driven and positioned in the X-axis direction with respect to the Y beam 105 by the X linear motor 106. Thereby, the mounting head 108 is freely positioned on the XY plane.
- the mounting head 108 is provided with a plurality of suction nozzles 110. Each suction nozzle 110 sucks and holds a component, and is driven in the Z direction to mount the component at the position of the mounting target 112 on the substrate 109.
- the Y beam 105, the Y linear motors 101 and 103, and the X linear motor 106 can be expressed as an example of a positioning system.
- the mounting head 108 in addition to the Y-axis position information from the Y encoders 102 and 104, and the X-axis position information from the X encoder 107, the mounting target 112 based on the captured image of the camera 111, which is an example of the imaging unit provided in the mounting head 108.
- the position information is used for driving and positioning.
- the drive of the mounting head 108 and the suction nozzle 110 necessary for component mounting is performed by the control device 113.
- the control device 113 includes a memory and a processor, performs operations for controlling the component mounting apparatus, including FIG. 6 described later, and instructs each component.
- the display unit 114 notifies the operator of the driving status, mounting state, device abnormality information, and the like.
- the display unit 114 since the display unit 114 is intended to notify the operator, the display unit 114 may be configured to notify the remote operator using a communication unit or the like without using the device itself.
- the control device 113 and the display unit 114 may be connected to other configurations by a wired network, or may be connected by a wireless network.
- the control device 113 and the display unit 114 may be portable terminals.
- the display unit 114 includes an input interface for an operator to perform work.
- FIG. 2 is a schematic diagram showing an example of positioning using image information.
- the mounting head 108 moves the component 203 sucked by the suction nozzle 110 to the specified mounting command position 201 (r0) using the position information of the X encoder 107 and the Y encoders 102 and 104.
- the mounting target 112 is displaced to the position r1 in the encoder coordinates due to positioning obstruction factors such as displacement and deformation of the substrate 109.
- the target position shift amount d at this time is expressed by Equation 1.
- the camera 111 observes the mounting target 112 in the field of view 202 and detects the position r1 of the mounting target 112.
- the control algorithm in the control device 113 corrects the target positional deviation amount d and positions the mounting head 108 at the position r1. Thereby, highly accurate mounting becomes possible.
- the position a1 positioned using the image information is the position r1 of the mounting target 112 and can be observed by the X encoder 107 and the Y encoders 102 and 104 after the mounting head 108 is positioned. Therefore, the target position deviation amount d can be calculated from Equation 2.
- FIG. 3 is a schematic diagram showing an example of a state after mounting.
- the component 203 is mounted on the substrate 109 by driving the suction nozzle 110 in the Z-axis direction.
- the position a2 where the component 203 is mounted deviates from the mounting target position r1.
- the mounting position deviation amount e between the mounted position a2 and the position target position r1 is expressed by Equation 3.
- the mounting position deviation amount e can be observed by the camera 111 after the component 203 is mounted.
- FIG. 4 is an example of a block diagram of an X-axis positioning control system using image information. Although FIG. 4 shows only the X-axis direction, the same applies to the Y-axis.
- the X-axis component Xr1 at the position r1 of the mounting target 112 is shifted by the substrate displacement disturbance Tt due to the displacement or deformation of the substrate 109 with respect to the X-axis component Xr0 at the mounting command position r0. Therefore, the purpose of the positioning control system is to position the suction nozzle 110 at the mounting target X-axis position Xr1.
- the camera 111 detects the image X-axis position deviation Xc between the mounting target 112 in the field of view 202 and the current position, and feeds it back to the controller C401.
- the controller C401 performs a control calculation and inputs a command to the X-axis control target P402, thereby driving the mounting head 108 in the X-axis direction.
- the detection position Xs of the X encoder 107 is affected by the mechanism deformation disturbance Ts.
- a camera mechanism deformation disturbance Tc due to a deformation of a mechanism existing between the camera 111 and the X encoder 107 shifts the field of view 202 of the camera 111. Therefore, the image X-axis position deviation Xc is a relative deviation of the camera position obtained by adding the camera mechanism deformation disturbance Tc to the detection position Xs of the X encoder 107 with respect to the mounting target X-axis position Xr1.
- a mechanism such as the mounting head 108, the suction nozzle 110, and a support portion thereof is interposed at the tip of the suction nozzle 110 that holds the X encoder detection position Xs and the component 203. Therefore, in the X-axis direction Xa2 of the mounting position a2, the mounting head deformation disturbance Th and the suction nozzle deformation disturbance Tn are applied to the X encoder detection position Xs.
- the state quantities that can be directly observed during the positioning control are the X encoder detection position Xs and the image X axis position deviation Xc.
- the mounting command X-axis position Xr0 is known in advance because of the command value. Equation 4 is a response characteristic of the X encoder detection position Xs.
- Equation 5 is a characteristic of the X encoder detection position Xs when Equation 4 is allowed to elapse for an infinite time, that is, the positioning position a1 in the X axis direction Xa1. From Equation 5, the positioning control system using the image information causes the X encoder detection position Xs to follow the mounting target X axis position Xr1. Further, the influence of the mechanism deformation disturbance Ts can be compressed and removed. However, the camera mechanism deformation disturbance Tc remains.
- the X-axis component Xd of the target position deviation amount d is expressed by Equation 6. That is, the target X-axis position deviation amount Xd has information on the substrate deviation disturbance Tt and the camera mechanism deformation disturbance Tc.
- Equation 7 is a response characteristic of the image X-axis position deviation Xc.
- Equation 8 is the image X-axis position deviation Xc when Equation 7 is allowed to elapse for an infinite time.
- the positioning control system using the image information performs control so that the image X-axis position deviation Xc becomes zero.
- Equation 9 is a response characteristic of the X-axis position Xn of the suction nozzle 110.
- the component mounting X-axis position Xa2 is the suction nozzle X-axis position Xn when Equation 9 is allowed to elapse for an infinite time. From Equation 10, the component mounting X-axis position Xa2 follows the mounting target X-axis position Xr1. However, the camera mechanism deformation disturbance Tc, the mounting head mechanism deformation disturbance Th, and the suction nozzle deformation disturbance Tn remain.
- the positioning control system using the image information shown in FIG. 4 for example, at least the camera mechanism deformation disturbance Tc, the mounting head mechanism deformation disturbance Th, and the suction nozzle deformation disturbance Tn are detected, and the positioning accuracy is deteriorated. It is necessary to notify as abnormal.
- Equation 11 is an X-axis component Xe of the mounting position deviation amount e.
- the mounting X-axis positional deviation amount Xe has information on camera mechanism deformation disturbance Tc, mounting head mechanism deformation disturbance Th, and suction nozzle deformation disturbance Tn. Note that the mounted X-axis positional deviation amount Xe can be observed by the camera 111 after the component 203 is mounted.
- FIG. 4 shows an example of a positioning control system using image information, and the configuration of the control system is not limited to FIG.
- the controller C401 may input the detection position Xs by the X encoder 107.
- the substrate displacement disturbance Tt, the camera mechanism deformation disturbance Tc, the mounting head mechanism deformation disturbance Th, and the suction nozzle deformation disturbance Tn which are positioning obstruction factors, change slowly due to thermal deformation even when there is no device abnormality.
- the apparatus abnormality changes with a time constant in which the camera mechanism deformation disturbance Tc is smaller than the thermal deformation.
- This device abnormality may be equal to or less than a time constant obtained by multiplying A by a normal disturbance change (A is less than 1). Further, the time constant of the disturbance change within the past specified time may be used as the reference time constant.

- the trend of the deviation amount e is calculated and stored.
- Trends can be represented by moving averages.
- the moving average may include a simple moving average that does not weight data (d and e in this embodiment), a weighted moving average that performs weighting, an exponential moving average that changes weights exponentially, and other moving averages.
- Parameters for obtaining the trend can be arbitrarily set by the operator via the display unit 114, and can be changed by the control device 113 according to a predetermined program.
- a parameter for obtaining a trend for example, the number of data, and when the trend is an exponential moving average, a smoothing coefficient can be considered, but other parameters can also be included.
- FIG. 7 is an example of the shift amount trend 4 of the target position shift amount d and the mounting position shift amount e calculated and stored by the shift trend calculation flow 602.
- the trend of these deviation amounts is stored including the past ones.
- the time to be stored may be a specified time or may be all from the time when the apparatus is activated.
- the specified time to be stored may be longer than the time constant of disturbance change caused by normal deformation.
- the target positional deviation amount d can be expressed as a first positional deviation amount.
- at least two images are required to obtain the trend of the target position deviation amount d, and the images for obtaining the trend of the target position deviation amount d are the first image and the first image later than the first image. It can be expressed as including the obtained second image.

- the drive continuation enable flag is raised in the drive continuation enable flag erection flow 614, and then the process proceeds to the end flag 615 to display the abnormality diagnosis flow 506. finish.
- the abnormal part diagnosis flow 604 is classified into three abnormal parts according to a deviation amount trend in which a sudden change has occurred.
- the camera abnormality display flow 605 displays on the display unit 114 that an abnormality has occurred in the camera 111 mechanism, and proceeds to the drive continuation disable flag standing up flow 613.
- the drive continuation disable flag rising flow 613 moves to the device stop flow 508 and stops the device by raising the drive continuation disable flag.
- the process proceeds to the substrate abnormality return flow 606.
- the change in only the target position deviation d is due to the substrate 109 deviation disturbance Tt.
- the drive mechanism system is a structure for moving the mounting head 108 such as the X linear motor 106, the X encoder 107, the Y linear motors 101 and 103, the Y encoders 102 and 104, and the Y beam 105.
- Substrate abnormality return 606 performs an operation for correcting a shift of the substrate 109.
- the correction of the displacement of the substrate 109 is, for example, by discharging the substrate 109 at the time of detecting an abnormality and mounting it on the new substrate 109, observing and correcting the displacement amount of the substrate 109 by observing the feature points on the substrate 109, etc. It can be done by the method.
- the substrate abnormal recovery possibility flow 607 confirms whether or not the deviation of the substrate 109 has been corrected, and if so, by raising the drive continuation enable flag in the drive continuation enable flag raising flow, the process proceeds to the end flag 507 to stop the apparatus. Without moving to the next component 203 mounting. If the deviation of the substrate 109 cannot be corrected in the substrate abnormality recovery possibility flow 607, there is a high possibility that the abnormality is in the drive mechanism system, so the process proceeds to the drive unit abnormality display flow 608 and the display unit 114 displays an abnormality in the drive unit. Is displayed to notify the operator. An abnormality in the drive mechanism system is an abnormality that can cause the apparatus to become inoperable. Therefore, by raising the drive continuation disabling flag in the drive continuation impossibility flag standing up flow 613, the process proceeds to the apparatus stop flow 508 and the apparatus is stopped.
- the process proceeds to the mounting head abnormality diagnosis flow 609.
- the mounting position deviation e changes due to the mounting head 108 mechanism deformation disturbance Th or the suction nozzle 110 deformation disturbance Tn. Therefore, if a sudden change is observed only in FIG. 7B, that is, the mounting position deviation e, it is specified that the mounting head 108 or the suction nozzle 110 is abnormal.
- the mounting head abnormality diagnosis flow 609 identifies whether the cause of the mounting position deviation e is due to either the mounting head 108 or the suction nozzle 110.
- FIG. 8 is an example of the mounting position deviation amount e trend for each suction nozzle 110.

- the mounting head 108 supports all the suction nozzles 110. Accordingly, when a sudden change is observed at the same time in the mounting deviation amount e trend of the plurality of suction nozzles 110, the sudden change in the mounting position deviation amount e trend is due to the mounting head mechanism deformation disturbance Th. It can be identified that the mounting head 108 is abnormal.
- the sudden change in the mounting position deviation amount e trend is the deformation of the suction nozzle. This is due to the disturbance Tn and can be identified as an abnormality of the suction nozzle 110. Furthermore, it is also specified that the suction nozzle 110 whose mounting position shift amount e trend has suddenly changed, that is, the abnormality of the first suction nozzle 110 in FIG. 8B. Similarly, when a sudden change is observed only in the mounting deviation amount trend e2 of the second suction nozzle 110, it is an abnormality of the second suction nozzle 110.

Accordingly, the mounting of the component 203 can be continued until the abnormality of the suction nozzle 110 is repaired, and a significant reduction in productivity can be prevented.
- an abnormality is diagnosed by detecting a sudden change in the shift amount trend at time td, but the past shift amount trend is stored as described above. Therefore, since the time td0 at which a sudden change in the deviation amount trend is started can be detected, the apparatus abnormality occurrence time td0 can be specified. Further, the mounted substrate 109 after the occurrence of the device abnormality is affected by the device abnormality and is likely to be a defective product. On the other hand, the mounted substrate 109 before the occurrence of the device abnormality is highly likely to be a non-defective product.
