DESCRIPTION OF EMBODIMENTS

Hereinafter, the present embodiment will be described with reference to the drawings.FIG.1is a schematic explanatory diagram illustrating an example of mounting system10of the present disclosure.FIG.2is an explanatory diagram schematically illustrating configurations of mounting device15and board S. In the present embodiment, a left-right direction (X-axis), a front-rear direction (Y-axis), and an up-down direction (Z-axis) are as illustrated inFIGS.1and2.

Mounting system10is configured as, for example, a production line in which mounting devices15executing a mounting process for components P on board S serving as a mounting target are arranged in a conveyance direction of board S. Here, a mounting target is described as board S but is not particularly limited as long as component P is mounted thereon, and may be a substrate having a three-dimensional shape. As illustrated inFIG.1, mounting system10is configured to include printing device11, printing inspection device12, storage section13, management PC14, mounting device15, automatic conveyance vehicle16, loader18, host PC60, and the like. Printing device11is a device that prints a solder paste or the like on board S. Printing inspection device12is a device that inspects a state of the printed solder.

Mounting device15is a device that picks up component P and mounts component P on board S. Mounting device15has a function of executing a mounting inspection process for inspecting whether a component on board S is missing or not or a state of a component disposed on board S. Mounting device15includes board processing section22, supply section24, pickup/imaging section27, mounting section30, and mounting control section40. As illustrated inFIG.2, mounting control section40is configured as a microprocessor centered on CPU41, and controls the entire device. Mounting control section40includes memory section42and inspection section45. Memory section42stores mounting condition information43, board information44, and the like. Mounting condition information43is a production job, and includes information such as information of component P, a disposition order in which component P is mounted on board S, a disposition position, an attachment position of feeder25from which component P is picked up, and the like. Board information44is information for managing the mounting state or the like of board S, and includes, for example, a picked-up state or an inspection result when component P is mounted, and a remounting result of a missing component. The missing component means that component P is not present on board S for some reason although a mounting process for component P is performed. Board information44is transmitted to host PC60and stored as a board information database for production management. Inspection section45is, for example, a functional block that inspects a state of board S or disposed component P based on an image obtained by imaging board S. Mounting control section40outputs control signals to board processing section22, supply section24, and mounting section30, and also receives signals from board processing section22, supply section24, and mounting section30.

Board processing section22is a unit that carries in, conveys, fixes at a mounting position, and carries out board S. Board processing section22has a pair of conveyor belts extending in the left-right direction and spaced apart from each other in the front-rear direction inFIG.2. Board S is conveyed by these conveyor belts. Board processing section22includes two pairs of the conveyor belts, and can convey and fix two boards S simultaneously. Supply section24is a unit that supplies component P to mounting section30. Supply section24attaches feeder25including a reel around which a tape serving as a holding member holding component P is wound to at least one attachment section. Feeder25includes a controller (not illustrated). The controller stores information such as an ID of the tape included in feeder25, the type of component P, and the remaining number of components P. When feeder25is attached to the attachment section, the controller transmits information regarding feeder25to mounting control section40. Supply section24includes a tray unit having tray26serving as a holding member on which multiple components P are arranged and placed.

Pickup/imaging section27is a device that captures images of one or more components P in a state of being picked up and held by mounting head32. Pickup/imaging section27is disposed between board processing section22and supply section24. An imaging range of pickup/imaging section27is located above pickup/imaging section27. Pickup/imaging section27captures an image of component P when mounting head32holding component P passes over pickup/imaging section27, and outputs the captured image to mounting control section40. Based on the captured image, mounting control section40may execute, for example, inspection as to whether a shape and a part of component P are normal, or detection of a deviation amount of a position, rotation, or the like at the time of picking up component P.

Mounting section30is a unit that picks up component P from supply section24and disposes component P on board S fixed to board processing section22. Mounting section30includes head moving section31, mounting head32, nozzle33, inspection/imaging section34, and nozzle storage section35. Head moving section31includes a slider moved by being guided by guide rails in the XY-directions, and a motor that drives the slider. Mounting head32picks up one or more components P and is moved in the XY-directions by head moving section31. Mounting head32is detachably attached to the slider. One or more nozzles33are detachably attached to a lower surface of mounting head32. Nozzle33picks up component P by using a negative pressure. A pickup member that picks up component P may be a mechanical chuck or the like that mechanically holds component P in addition to nozzle33. Inspection/imaging section34is a camera that captures an image of a region below mounting head32, and captures an image of, for example, not only component P disposed on board S but also a reference mark, a 2D code, or the like formed on board S. Inspection/imaging section34is disposed on the lower surface side of the slider to which mounting head32is attached, and is moved in the XY-directions in accordance with the moving of mounting head32. Inspection/imaging section34outputs the image data of multiple missing component inspection regions A (refer toFIG.2) set on board S on which component P is disposed to mounting control section40. Mounting control section40causes inspection section45to analyze the image data.

Storage section13is a storage location for temporarily storing feeder25used in mounting device15. Storage section13is provided under a conveyance device between printing inspection device12and mounting device15. Storage section13has an attachment section in the same manner as supply section24. When feeder25is connected to the attachment section, the controller of feeder25transmits the information regarding feeder25to management PC14. In storage section13, feeder25may be transported by automatic conveyance vehicle16, or feeder25may be transported by an operator. Management PC14is a device that manages feeder25, stores execution data or the like executed by loader18, and manages loader18. Automatic conveyance vehicle16automatically conveys feeder25, a member used in mounting system10, and the like between a warehouse (not illustrated) and storage section13. The warehouse stores feeder25and other members.

Loader18is a mobile work device, which is a device that is moved in a moving region in front of mounting system10(refer to dotted lines inFIG.1), and automatically collects and provides members or the like necessary for a mounting process, such as feeder25of mounting device15. Loader18includes moving control section50, memory section53, accommodation section54, exchange section55, moving section56, and communication section57. Moving control section50is configured as a microprocessor centered on CPU51and controls the entire device. Moving control section50controls the entire device such that feeder25is collected from supply section24or feeder25is provided to supply section24, and feeder25is moved to and from storage section13. Memory section53is, for example, an HDD that stores various data such as a processing program. Accommodation section54has an accommodation space for accommodating feeder25. Accommodation section54is configured to be able to accommodate, for example, four feeders25. Exchange section55is a mechanism that moves feeder25in and out as well as moving feeder25in the up-down direction. Exchange section55has a clamp section that clamps feeder25, a Y-axis slider that moves the clamp section in the Y-axis direction (front-rear direction), and a Z-axis slider that moves the clamp section in the Z-axis direction (up-down direction). Exchange section55executes attachment and detachment of feeder25at mounting attachment section28, and attachment and detachment of feeder25at buffer attachment section29. Moving section56is a mechanism that moves loader18in the X-axis direction (the left-right direction) along X-axis rail19disposed in front of mounting device15. Communication section57is an interface that performs exchange of information with external devices such as management PC14and mounting device15. Loader18outputs the current position or details of executed work to management PC14. Loader18is capable of collecting and providing feeder25, but may be configured to collect and provide members related to the mounting process, such as mounting head32, nozzle33, a solder cartridge, a screen mask, and a backup pin for supporting a board.

Host PC60(refer toFIG.1) is configured as a server that stores and manages information used by each device of mounting system10, for example, a production planning data including multiple pieces of mounting condition information43and a board information database including multiple pieces of board information44.

Next, an operation of mounting system10according to the present embodiment configured as described above, first, a process in which mounting device15mounts component P on board S will be described.FIG.3is a flowchart illustrating an example of a mounting process routine executed by CPU41of mounting control section40of mounting device15. This routine is stored in memory section42of mounting device15and executed in accordance with a starting instruction from an operator. When this routine is started, first, CPU41reads and acquires mounting condition information of board S to be produced this time (S100). CPU41reads mounting condition information43that is acquired from host PC60and stored in memory section42. Next, CPU41causes board processing section22to convey board S to a mounting position and to perform a process of fixing board S (S110). Next, CPU41sets a component that is a pickup target based on mounting condition information43(S120), causes mounting head32to pick up component P from feeder25at a preset position and to move component P above pickup/imaging section27(S130).

Next, CPU41causes pickup/imaging section27to perform a process of imaging component P in the state of being picked up by mounting section30, and calculates a deviation amount based on a reference position (S140).FIG.4is an explanatory diagram illustrating an example of mounting head32having picked up component P when viewed from the bottom.FIG.4illustrates an example in which mounting head32includes four nozzles33. InFIG.4, component P at the reference position is indicated by dotted lines. As illustrated inFIG.4, a positional deviation in the XY-coordinate directions occurs in component Pa with respect to the reference position, and a rotational deviation in which the component is rotated with respect to the reference position to cause an inclination occurs in component Pb. As described above, in mounting section30, a picked-up state of component P may be changed. When the deviation amount is calculated, CPU41checks whether the positional deviation amount of component P is within a threshold value, exceeds the threshold value and within an allowable value, or exceeds the allowable value (S150). In mounting device15, a predetermined threshold value at which a probability of a missing component or the like occurring when exceeding a positional deviation amount of component P in a picked-up state of component P is increased is empirically determined, and an allowable value that is larger than the threshold value and at which a normal product cannot be obtained even if component P is disposed on board S when exceeding the threshold value is also empirically determined.

When the positional deviation amount of component P exceeds the threshold value and is within the allowable value in S150, CPU41stores component P as a missing predicted component in board information44(S160). In this case, CPU41stores a disposition position number of corresponding component P in association with information as the missing predicted component in board information44including identification information (ID) of board S After S160or when the positional deviation amount of component P is within the threshold value in S150, CPU41checks whether the rotational deviation amount of component P is within the threshold value, exceeds the threshold value and within the allowable value, or exceeds the allowable value (S170). In mounting device15, a predetermined threshold value at which a probability of a missing component or the like occurring when exceeding a rotational deviation amount in a picked-up state of component P is increased is empirically determined, and an allowable value that is larger than the threshold value and at which a normal product cannot be obtained even if component P is disposed on board S when exceeding the threshold value is also empirically determined.

When the rotational deviation amount of component P exceeds the threshold value and is within the allowable value in S170, corresponding component P is stored in board information44as a missing predicted component (S180). In this case, CPU41stores a disposition position number of corresponding component P in association with information as the missing predicted component in board information44including identification information (ID) of board S. As described above, the information obtained from an image captured by pickup/imaging section27and possibly leading to a defect thereafter is stored in board information44. According to board information44, it is possible to manage by which mounting device15component P mounted may be defective.

On the other hand, when the positional deviation amount of component P exceeds the allowable value in S150, or when the rotational deviation amount of component P exceeds the allowable value in S170, CPU41determines that a board on which component P is to be mounted will be a defective board, sets corresponding component P as a non-mounting component not used for a mounting process, and then performs a process of discarding component P (S190). In a case where mounting head32holds multiple components P, when there is a non-mounting component among components, CPU41discards the non-mounting component in a predetermined discarding location after disposing normal components P on board S. Components P instead of discarded components P may be collectively mounted at the end of the mounting process of mounting device15.

After S190, after S180, or when the rotational deviation amount of component P is within the threshold value in S170, CPU41causes mounting section30to execute a process of disposing component P (S200). Subsequently, CPU41determines whether the mounting process for board S that is currently fixed to the mounting position has been finished (S210), and executes the processes in and after S120when the mounting process has not been finished. That is, CPU41sets component P to be picked up and disposed next, causes mounting section30to pick up component P, stores missing predicted component information in board information44according to a state of component P, or executes a process of disposing component P on board S while discarding a non-mounting component (S120to S200). On the other hand, when the mounting process for board S that is currently fixed to the mounting position is finished in S210, CPU41executes a missing component inspection and remounting process (S220). The missing component inspection and remounting process, which will be described later in detail, is a process of inspecting the presence or absence of a missing component on board S, and executing a remounting process for the corresponding component when a component is missing. After the missing component inspection and remounting process in S220is executed, CPU41causes board processing section22to discharge board S for which the mounting has been finished (S230), and determines whether or not production of all boards S set in mounting condition information43has been completed (S240). When the production of all boards S has not been completed, CPU41executes the processes in and after S110, whereas when the production of all boards S has been completed, CPU41finishes this routine. Since such mounting process is executed by each of mounting devices15, information regarding a position where a missing predicted component is present in specific board S is integrated and stored in board information44.

Here, the missing component inspection and remounting process in S220will be described.FIG.5is a flowchart illustrating an example of the missing component inspection and remounting process routine. This routine is stored in memory section42of mounting device15, and is executed in S220of the mounting process routine after the mounting process in current mounting device15is finished. When this routine is started, first, CPU41reads and acquires board information44of board S which is fixed to board processing section22and for which a mounting process in mounting device15is finished (S300). Next, in S310, CPU41sets missing component inspection region A corresponding to the missing predicted component. CPU41may determine whether or not there is a missing predicted component in entire missing component inspection region A of board S on which the inspection is executed by mounting device15, and may omit the missing component inspection process without setting missing component inspection region A when there is no missing predicted component. In this case, when there is a missing predicted component, CPU41may set a region including a disposition region in which the missing predicted component is disposed as missing component inspection region A, and execute the missing component inspection process. In this mounting device15, since the missing component inspection process is executed only on a region where a missing component may occur, it is possible to further reduce the inspection time.

Next, CPU41causes inspection/imaging section34to perform a process of imaging set missing component inspection region A (S320). CPU41controls head moving section31to move inspection/imaging section34onto missing component inspection region A of board S, and causes inspection/imaging section34to image missing component inspection region A. Next, CPU41determines whether or not a component is missing in a captured image by using a reference image captured when component P is appropriately disposed (S330). When a component is missing in imaged missing component inspection region A, a foreign object inspection region corresponding to a position of the missing component is set (S340), and a foreign object inspection process of inspecting a foreign object on board S is executed (S350). This foreign object inspection process is inspection because a component that has missed is present as a foreign object anywhere in board S, so that a defective board will not be manufactured. The setting of the foreign object inspection region may be, for example, a region around the missing component position where the presence of the foreign object adversely affects board manufacturing. For example, the foreign object inspection region may be set to a region where component P is not currently disposed and component P is disposed by next mounting device15or after, a disposition region of component P having a special shape in which component P that is missing enters a lower part of already disposed component P, a disposition region of an expensive component, or the like. For example, in a region where component P is not disposed has a low possibility that a defective board will occur due to the presence of a foreign object, the foreign object inspection may be omitted. The foreign object inspection process may be performed, for example, by capturing an image of set missing component inspection region A with inspection/imaging section34, and comparing the captured image with an image obtained by appropriately disposing component P on board S.

Subsequently, CPU41determines whether or not there is a foreign object in missing component inspection region A (S360), and notifies the operator of the presence of the foreign object (S370). The operator may be notified, for example, by displaying a message indicating the presence of the foreign object on the operation panel or outputting a sound. In this case, CPU41may temporarily stop the operation of mounting device15, obtain an input for restart from the operator, and then perform the processes in and after S370. On the other hand, when there is no foreign object in missing component inspection region A in S360, CPU41executes a remounting process for component P that is the missing component (S380to S400). In the remounting process, CPU41determines whether or not component P that is the missing component is held in feeder25or tray26and is present in supply section24(S380), and outputs a command for causing loader18to provide and convey component P when there is no corresponding component P in supply section24(S390). For example, inFIG.2, when component P1is a component mounted by this mounting device15, component P1is substantially present in supply section24. On the other hand, when component P2is mounted before this mounting device15, component P2may not be present in supply section24. In this case, for example, CPU41causes loader18to provide component P2in storage section13to supply section24. Component P in storage section13is managed by management PC14, so that whether or not missing component P is present in storage section13may be ascertained from the management information of management PC14. When there is no corresponding component P in storage section13, CPU41may cause automatic conveyance vehicle16to convey corresponding component P to storage section13. After outputting the command in S390, CPU41waits until component P is conveyed to supply section24, and executes the following processes after component P is conveyed to supply section24. When this command is received, loader18moves feeder25or tray26holding corresponding component P from storage section13to mounting device15for which an instruction is given.

After S390or when missing component P is present in supply section24in S380, CPU41causes mounting section30to execute a remounting process for missing component P (S400). In the remounting process, CPU41causes mounting head32to pick up corresponding component P from supply section24, and moves component P to a position of the missing component ascertained in S330and disposes component P. Nozzle33for picking up missing component P may be predicted in advance, stored in nozzle storage section35of mounting section30, or may be moved from storage section13by loader18. Mounting head32is also the same as nozzle33. As described above, since mounting device15has the function of the inspection device and the function of the mounting device, it is possible to easily remount component P that is a missing component after the missing component inspection is performed.

After S400, after S370, or when no component is missing in missing component inspection region A in S330, CPU41determines whether or not there is next missing component inspection region A (S410), and executes the processes in and after S310when there is next missing component inspection region A. That is, CPU41sets next missing component inspection region A in S310, performs the missing component inspection process, and executes the foreign object inspection process or the remounting process as necessary. On the other hand, when there is no next missing component inspection region A in S410, that is, when all the missing component inspections are executed, information regarding details of the executed processes is included in board information44, updated, and stored in memory section42(S420), and this routine is finished.

Here, correspondence relationships between configuration element of the present embodiment and configuration element of the present disclosure will be clarified. Supply section24of the present embodiment corresponds to a supply section, mounting section30corresponds to a mounting section, inspection/imaging section34corresponds to an inspection/imaging section, mounting control section40corresponds to a control section, feeder25and tray26correspond to a holding member, nozzle33and the mechanical chuck correspond to a pickup member, and pickup/imaging section27corresponds to pickup/imaging section. In the present embodiment, an example of the inspection and mounting method of the present disclosure is also clarified by describing the operation of mounting device15.

In mounting device15of the present embodiment described above, the missing component inspection process of detecting whether a component P on board S is missing or not is executed by using a captured image of board S serving as a mounting target, and when component P is missing, mounting section30is controlled to pick up missing component P from supply section24and dispose component P on board S. Since mounting device15has a configuration for executing the mounting process and a configuration for executing the inspection process, it is possible to remount this missing component P after executing the missing component inspection. Therefore, it is possible to execute production more efficiently compared with a case where an operator executes an operation for a missing component. Mounting system10includes multiple mounting devices15, and CPU41executes the missing component inspection process on board S on which the mounting process is performed by other mounting device15, and controls mounting section30to pick up missing component P that should have been mounted by other mounting device15from supply section24and dispose missing component P on board S when component P is missing. In this mounting device15, since missing component P that should have been mounted by other mounting device15can also be remounted, production can be executed more efficiently.

Supply section24is provided with feeder25or tray26as a holding member that holds component P, and mounting system10further includes loader18as a mobile work device including accommodation section54that accommodates feeder25or the like to collect feeder25from supply section24and/or to attach feeder25or the like to supply section24. In this case, when component P on board S is missing and missing component P is not present in supply section24, CPU41moves feeder25holding the missing component to the supply section by loader18. In this mounting device15, even in a case where component P mounted by other mounting device15is not present in mounting device15, component P can be secured, and thus production can be executed more reliably and efficiently. When component P on board S is missing and nozzle33serving as a pickup member that picks up missing component P is not in mounting section30, CPU41causes loader18to move nozzle33for picking up this missing component P to mounting section30. In this mounting device15, even in a case where a pickup member for picking up component P mounted by other mounting device15is not present in this mounting device15, component P can be picked up, and thus production can be executed more reliably and efficiently.

CPU41executes the missing component inspection process by using a captured image of component P captured by inspection/imaging section34and in a state in which component P is picked up by mounting section30. In this mounting device15, it is possible to execute production more efficiently by using a captured image of component P in a picked-up state. CPU41executes the missing component inspection process on a disposition region in which component P for which a value of a rotational position as a pickup position or a pickup posture of component P obtained from the captured image of component P in a state of being picked up by mounting section30exceeds a predetermined threshold value is disposed. In mounting device15, since a region where the missing component inspection process is executed is specified based on the picked-up state of component P, the production can be executed more efficiently by executing the missing component inspection process more efficiently. CPU41acquires, from board information44, information regarding a pickup position or a pickup posture of component P obtained based on a captured image that is captured by pickup/imaging section27of other mounting device15, and executes the missing component inspection process. In this mounting device15, production can be executed more efficiently by executing the missing component inspection process by using information obtained by other mounting devices15.

When component P on board S is missing, CPU41executes the foreign object inspection process for detecting a foreign object present on board S. In mounting device15, the production can be executed more efficiently by executing the foreign object inspection process only when component P is missing. CPU41executes the foreign object inspection process on some or all of regions where component P is mounted on board S. In mounting device15, production can be executed more efficiently by executing the foreign object inspection process only on a region related to component mounting. Since CPU41executes the foreign object inspection process on a region where component P is mounted in the subsequent mounting process, a disposition region of a component having a special shape in which a missing component is embedded, or a disposition region of an expensive component, it is possible to further suppress the occurrence of a defective board, an increase in production cost, or the like.

Needless to say, the present disclosure is not limited to the embodiment that has been described, and can be carried out in various forms without departing from the technical scope of the present disclosure.

For example, in the above embodiment, the missing component inspection process is executed on component P of board S that has been subjected to the mounting process by other mounting device15; however, the configuration is not particularly limited to this, and the missing component inspection process may be performed on only component P that has been subjected to the mounting process by current mounting device15. In this mounting device15, since component P is inevitably present in mounting section30, it is easy to perform the remounting process. Loader18conveys component P when there is no component P to be remounted; however, the configuration is not particularly limited to this, and loader18may be omitted, and component P may be conveyed by automatic conveyance vehicle16or may be conveyed by an operator.

In the above embodiment, pickup/imaging section27captures an image in a state in which component P is picked up by mounting head32and executes the missing component inspection process by using the captured image; however, the configuration is not particularly limited to this, and the missing component inspection process may be executed without using a deviation amount obtained by using the captured image from pickup/imaging section27. In particular, CPU41may execute the missing component inspection process on all the regions of board S. Similarly, in the above embodiment, the foreign object inspection region is set and the foreign object inspection process is performed only on that region; however, the configuration is not particularly limited to this, and the foreign object inspection process may be executed on all the regions of board S. This mounting device15requires an inspection time but can execute more reliable missing component inspection and foreign object inspection.

In the above embodiment, the present disclosure is described as mounting system10or mounting device15, but may be a control method for mounting device15or a program for realizing the control method for mounting device15.

Here, the mounting device, the mounting system, and the inspection and mounting method of the present disclosure may be configured as follows. For example, in the mounting device according to the present disclosure, the mounting system may include the multiple mounting devices, the control section may execute the missing component inspection process on the mounting target that has been subjected to a mounting process by other mounting device, and when a component is missing, control the mounting section to pick up the missing component that should have been mounted by the other mounting device from the supply section and dispose the missing component on the mounting target. In this mounting device, since a missing component that should have been mounted by other mounting device can also be remounted, production can be executed more efficiently.

In the mounting device according to the present disclosure used in the mounting system including the multiple mounting devices, the supply section may be provided with a holding member holding the component, and the mounting system may further include a mobile work device including an accommodation section that accommodates the holding member to collect the holding member from the supply section and/or to move the holding member to the supply section, and the control section may cause the mobile work device to move the holding member holding a missing component to the supply section when a component on the mounting target is missing and the missing component is not present in the supply section. In this mounting device, even in a case where a component mounted by other mounting device is not present in the mounting device, the component can be secured, and thus production can be executed more reliably and efficiently.

In the mounting device according to the present disclosure used in the mounting system including the multiple mounting devices, the mounting section may be able to attach and detach a pickup member that picks up the component, the supply section may be provided with a holding member holding the component, the mounting system may further include a mobile work device including an accommodation section that accommodates the holding member to collect the holding member from the supply section and/or to move the holding member to the supply section, and the control section may cause the mobile work device to move the pickup member that picks up a missing component to the mounting section when a component on the mounting target is missing and the pickup member that picks up the missing component is not present in the mounting section. In this mounting device, even in a case where the pickup member that picks up a component mounted by other mounting device is not present in the mounting device, the component can be picked up, and thus production can be executed more reliably and efficiently.

The mounting device of the present disclosure may include a pickup/imaging section that captures an image of the component in a state of being picked up by the mounting section, and the control section may execute the missing component inspection process by using the captured image of the component in a state of being picked up by the mounting section. In this mounting device, it is possible to execute production more efficiently by using the captured image of the component in a picked-up state.

In the mounting device of the present disclosure including the pickup/imaging section, when the captured image of the component in a state of being picked up by the mounting section is used, the control section may execute the missing component inspection process on a disposition region in which the component for which a value of a pickup position and/or a pickup posture of the component obtained from the captured image exceeds a predetermined threshold value is disposed. In this mounting device, since the region for executing the missing component inspection process is specified based on the picked-up state of the component, it is possible to execute production more efficiently by executing the missing component inspection process more efficiently.

In the mounting device of the present disclosure including the pickup/imaging section, the mounting system may include the multiple mounting devices, and the control section may acquire information regarding the pickup position and/or the pickup posture of the component based on the captured image that is captured by the pickup/imaging section of other mounting device, and execute the missing component inspection process. In this mounting device, production can be executed more efficiently by executing the missing component inspection process by using the information obtained by other mounting device.

The control section may control the inspection/imaging section to execute a foreign object inspection process for detecting a foreign object present on the mounting target when a component on the mounting target is missing. In this mounting device, production can be executed more efficiently by executing the foreign object inspection process only when a component is missing. In this case, the control section may execute the foreign object inspection process on some or all of regions where components are mounted on the mounting target. In this mounting device, production can be executed more efficiently by executing the foreign object inspection process only on a region related to component mounting. In this case, the control section may execute the foreign object inspection process on a region where a component is to be mounted in the subsequent mounting process, a disposition region where a component having a special shape is disposed, or a disposition region where an expensive component is disposed.

The mounting system of the present disclosure includes any of the mounting devices described above. Since the mounting system has any of the mounting devices described above, it is possible to achieve the same effects.

The inspection and mounting method of the present disclosure is a method used in a mounting system having a mounting device including a supply section that holds a component, a mounting section that picks up the component from the supply section and performs a mounting process for the component on a mounting target, and an inspection/imaging section that captures an image of the mounting target, the inspection and mounting method including: (a) a step of executing a missing component inspection process of detecting whether a component on the mounting target is missing or not by using a captured image of the mounting target; and (b) a step of, when a component is missing in the step (a), controlling the mounting section to pick up the missing component from the supply section and dispose the missing component on the mounting target.

In this inspection and mounting method, similarly to the mounting device described above, since it is possible to remount missing component P after the missing component inspection is executed, it is possible to more efficiently execute the production. The inspection and mounting method may employ the aspect of the mounting device described above, or may include a step of expressing the function of the mounting device described above.
