Description

[Technical Field]

[0001] The present invention relates to a component mounting apparatus and a component mounting system, and more particularly to a component mounting apparatus and a component mounting system that are provided with an imaging unit that captures an image of a component to be mounted on a board. [Background technology]

[0002] BACKGROUND ART Conventionally, component mounting devices and component mounting systems that include an imaging unit that captures an image of a component to be mounted on a board are known (see, for example, Patent Document 1).

[0003] The above-mentioned Patent Document 1 discloses a component mounter (component mounting device) equipped with a component imaging camera (imaging unit) that captures images of components to be mounted on a board. This component mounter is equipped with an image recognition system including a storage unit. The image recognition system is configured to classify images of components captured by the component imaging camera into normal images and abnormal images based on whether the images correctly recognize the pickup posture (position and angle) of the components. After classifying the images into normal images and abnormal images, the image recognition system stores both the normal images and the abnormal images in the storage unit. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2018 / 087932 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the image recognition system of the component mounter of Patent Document 1, the images captured by the component imaging camera must be classified into normal images and abnormal images, and then all images must be stored in a storage unit as normal images and abnormal images, making it difficult to suppress an increase in the storage capacity of the storage unit required for image storage. For this reason, in the image recognition system of Patent Document 1, it is desired to suppress an increase in the storage capacity of the storage unit required for image storage.

[0006] The present invention has been made to solve the above-mentioned problems, and one object of the present invention is to provide a component mounting device and a component mounting system that can suppress an increase in the memory capacity of the memory unit required for image storage. [Means for solving the problem]

[0007] In order to achieve the above object, a component mounting apparatus according to a first aspect of the present invention includes an imaging unit that captures an image of a component to be mounted on a board, and a control unit configured to enable a setting to save the component image as a saved image in the storage unit based on a condition for enabling a setting to save the component image of the component captured by the imaging unit in a storage unit, and the control unit enables the setting to save the component image as a saved image in the storage unit based on a condition for eliminating a defective state related to component mounting, after enabling the setting to save the component image as a saved image in the storage unit. Rumu Enabling Article The matter Based on whether the condition is met, control is performed to disable the setting for saving the component image as a saved image in the storage unit.

[0008] As described above, the component mounting device according to the first aspect of the present invention includes a control unit configured to enable a setting to save component images as saved images based on the satisfaction of a save enablement condition that enables the setting to save component images of components captured by the imaging unit in a storage unit. This prevents component images captured by the imaging unit from being saved in the storage unit unless the save enablement condition is satisfied, thereby suppressing an increase in the storage capacity of the storage unit required for image saving. Furthermore, when component images need to be saved in the storage unit, the component images can be automatically saved in the storage unit as saved images, making it easy to obtain component images that need to be saved in the storage unit. A component mounting device in a second aspect of the present invention includes an imaging unit that captures images of components mounted on a board, and a control unit configured to enable a setting to save the component image in the memory as a saved image based on satisfaction of a save activation condition that enables a setting to save the component image of the component captured by the imaging unit in a memory unit, the save activation condition having an activation condition based on an index for acquiring defects related to component mounting, the control unit configured to control saving the component image corresponding to the activation condition as a saved image in the memory unit based on satisfaction of the activation condition, and the control unit configured to control disabling the setting to save the component image as a saved image in the memory unit based on satisfaction of an disable condition that disables the setting to save the component image based on the index indicating that the defective state related to component mounting has been resolved. This allows the setting for saving component images to be disabled at an appropriate time based on the invalidation conditions, thereby preventing an increase in the number of saved images required to identify defects related to component mounting. 。

[0009] In the component mounting device according to the first aspect, the control unit is preferably configured to control the server to acquire the saved images. With this configuration, only the saved images from among the component images can be saved in the server's storage unit, thereby suppressing an increase in the storage capacity required for saving images in the server's storage unit.

[0010] In the aforementioned component mounting apparatus according to the first aspect, the save validating condition is preferably based on an index for acquiring a defect related to component mounting. Kuy The control unit has an enabling condition. Yes Based on the fulfillment of the activation conditions, Yes The control unit is configured to control the storage of component images corresponding to the validation conditions as saved images in the storage unit. With this configuration, the component images after the index has decreased to the point where the control unit identifies that a component mounting defect has occurred can be saved as saved images in the storage unit, so that images necessary for identifying the cause of the mounting defect can be saved.

[0011] In this case, the head further includes a nozzle that picks up a component to be mounted on the board, and the imaging unit includes a component imaging unit that picks up an image of the component picked up by the nozzle, Yes The enabling condition is at least one of the pickup rate, which is an index based on the number of times that the nozzle fails to pick up a component, and the recognition rate, which is an index based on the number of times that the component is not recognized based on the component image captured by the component imaging unit. With this configuration, component images after at least one of the pickup rate and the recognition rate has decreased can be saved as saved images in the storage unit, so that images necessary for identifying the cause of at least one of the pickup failure and the recognition failure can be saved.

[0016] The component mounting device according to the first aspect preferably further includes a temporary storage unit that is provided separately from the storage unit and that temporarily stores component images, and the control unit is configured to select, based on a storage activation condition, a component image to be transmitted to the server storage unit and stored in the server from among the component images stored in the temporary storage unit, and to store the selected component image as a saved image. With this configuration, multiple saved images can be stored in the temporary storage unit and then saved in the server, compared to a case where a component image is stored in the server storage unit every time an image is captured by the imaging unit, and therefore it is possible to reduce the processing required to save saved images in the server storage unit.

[0017] The first aspect of this invention 3 The component mounting system in this aspect includes a component mounting device including an imaging unit that images a component to be mounted on a board, and a server including a storage unit that acquires and stores component images of the component imaged by the imaging unit, wherein the component mounting device further includes a control unit configured to enable a setting to store the component images as saved images in the storage unit of the server based on a condition for enabling storage of the component images in the storage unit of the server, and the control unit disables the setting to store the component images as saved images in the storage unit based on a condition for eliminating a defective state related to component mounting after enabling the setting to store the component images as saved images in the storage unit. Rumu Enabling Article The matter Based on whether the condition is met, control is performed to disable the setting for saving the component image as a saved image in the storage unit.

[0018] The first aspect of this invention 3 In the component mounting system according to the above aspect, as described above, the component mounting device is provided with a control unit configured to enable a setting for saving component images as saved images in the server's storage unit based on satisfaction of a save enablement condition for enabling a setting for saving component images in the server's storage unit. This prevents component images captured by the imaging unit from being saved in the storage unit unless the save enablement condition is satisfied, thereby providing a component mounting system that can suppress an increase in the storage capacity of the storage unit required for image saving.

[0019] The first aspect of this invention 4The component mounting system according to this aspect includes a component mounting device including an imaging unit that images components to be mounted on a board, and a server including a memory unit that acquires and stores component images of the components imaged by the imaging unit, the component mounting device further including a control unit configured to enable a setting to store the component images in the server's memory as saved images based on a storage enablement condition that enables a setting to store the component images in the server's memory, the component mounting device further including an inspection device disposed downstream of the component mounting device, and a temporary memory unit provided separately from the server's memory that temporarily stores the component images, the storage enablement condition being an inspection failure condition based on a defect detection result of the inspection device detecting a mounting failure of a component on the board, the control unit being configured to control, based on the inspection failure condition, to select component images to be sent to the server from the component images stored in the temporary memory and store them in the server's memory as saved images. This allows component images after a component mounting failure has occurred to be stored in the memory as saved images, making it possible to store images necessary for identifying the cause of the component mounting failure. [Effects of the Invention]

[0020] According to the present invention, as described above, it is possible to suppress an increase in the storage capacity of the storage unit required for saving images. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

[0023] (Component mounting system) The configuration of a component mounting system 100 according to one embodiment of the present invention will be described with reference to FIGS.

[0024] 1, component mounting system 100 is a system that mounts (loads) components E (electronic components) such as ICs, transistors, capacitors, and resistors on a board P1 such as a printed circuit board to produce a production board P2 on which components E are mounted. Specifically, component mounting system 100 includes a component mounting line 1 and a server 2.

[0025] (Component mounting line configuration) The component mounting line 1 includes a printing device 11, a plurality of (two) component mounting devices 12, an inspection device 13, a reflow furnace 14, and an inspection device 15. Two or more component mounting lines 1 may be provided. Also, although two component mounting devices 12 are provided, one, or three or more may be provided.

[0026] (Printing device) The printing device 11 is a screen printing machine, and has the function of applying cream solder M (see FIG. 5) onto the mounting surface of the board P1.

[0027] (Component mounting equipment) 1 and 2, each of the plurality of component mounting devices 12 is configured to mount (load) a component E at a predetermined mounting position on a substrate P1 on which cream solder has been printed. Since each of the plurality of component mounting devices 12 has the same configuration, only the configuration of the downstream component mounting device 12 will be described below.

[0028] Here, in the component mounting device 12, the transport direction in which the substrate P1 is transported is the X1 direction, the opposite direction to the transport direction in which the substrate P1 is transported is the X2 direction, and the combined direction of the X1 and X2 directions is the X direction. Furthermore, the horizontal direction perpendicular to the X direction is the Y direction, one side of the Y direction is the Y1 direction, and the other side of the Y direction is the Y2 direction. Furthermore, the up-down direction perpendicular to the X and Y directions is the Z direction (up-down direction), one side of the Z direction is the Z1 direction (upward), and the other side of the Z direction is the Z2 direction (downward).

[0029] The component mounting device 12 has a base 120, a feeder arrangement unit 121, a board transport unit 122, a support unit 123, a pair of rail units 124, a head unit 125, a component imaging unit 126, a board imaging unit 127, a control unit 128, a memory unit 129, and a communication unit 1210. The component imaging unit 126 is an example of the "imaging unit" in the claims. The memory unit 129 is an example of the "temporary memory unit" in the claims.

[0030] The base 120 is a base on which each component is arranged in the component mounting apparatus 12. The base 120 has feeder arrangement sections 121 on both sides in the Y direction (the Y1 direction side and the Y2 direction side). A plurality of tape feeders 121a can be arranged in the feeder arrangement section 121. The tape feeder 121a is a component supply device that supplies components E to be mounted on the board P1. The tape feeder 121a holds a reel (not shown) around which a component supply tape is wound, which holds a plurality of components E at predetermined intervals.

[0031] The board transport unit 122 is configured to carry in the board P1 from outside the component mounting apparatus 12 and transport the board P1 in a transport direction (X1 direction). The board transport unit 122 has a pair of conveyors 122a and a drive unit (not shown).

[0032] The support portion 123 is configured to support the head unit 125 so that the head unit 125 can move in the X direction. The support portion 123 has a ball screw shaft 123a and a drive portion 123b.

[0033] The pair of rail portions 124 are configured to support the support portion 123 so that the support portion 123 can move in the Y direction. The rail portion 124 has a ball screw shaft 124a, a guide rail 124b, and a drive portion 124c.

[0034] The head unit 125 is a head unit for mounting components, and is configured to move in the Z1 direction (upward) of the board P1 and perform mounting work on the board P1. In other words, the head unit 125 is configured to mount components E on the board P1 fixed at the work position.

[0035] Specifically, the head unit 125 includes a head 125a, a Z-axis motor (not shown), and an R-axis motor (not shown). The head 125a is configured to hold the component E and to mount the component E at a predetermined mounting position (not shown) on the board P1. A plurality of (five) heads 125a are arranged in a line in the X direction.

[0036] Each of the plurality of heads 125a is connected to a pressure generator (not shown), and is configured to be able to hold (suck) a component E onto a nozzle N attached (mounted) to the tip thereof by the negative pressure generated by the pressure generator. Each of the plurality of heads 125a is also configured to be able to mount (place) a component E onto a substrate P1 by switching the negative pressure generated by the pressure generator to positive pressure. Here, the pressure generated on the nozzle N by the pressure generator is measured by a pressure sensor (not shown).

[0037] Each of the plurality of heads 125a is configured to be movable in the Z direction (up and down direction) by a Z-axis motor, and each of the plurality of heads 125a is configured to be rotatable around a rotation axis by an R-axis motor.

[0038] The component imaging unit 126 is configured to capture an image of the component E to be mounted on the board P1. That is, the component imaging unit 126 is a component imaging camera that captures an image of the component E held (sucked) by the nozzle N prior to mounting the component E on the board P1. The component imaging unit 126 is fixed on the base 120, and is configured to capture an image of the component E held (sucked) by the nozzle N from below (in the Z2 direction) the component E. This makes it possible to acquire a component image G1 of the component E captured by the component imaging unit 126, as shown in FIG. 3.

[0039] The board imaging unit 127 is attached to the head unit 125 and is a mark imaging camera that images an FI mark (fiducial mark: not shown) attached to the top surface of the board P1 prior to mounting the component E on the board P1. The FI mark is a mark for confirming the position of the board P1.

[0040] 4, the control unit 128 is configured to perform control to suck up components E from the tape feeder 121a using the nozzle N and mount them on the board P1. Specifically, the control unit 128 includes a CPU (Central Processing Unit) 128a, a memory unit 128b, etc., and controls the operation of the component mounting apparatus 12. The control unit 128 is electrically connected to the tape feeder 121a, the board transport unit 122, the support unit 123, the rail unit 124, the head unit 125, the component imaging unit 126, the board imaging unit 127, the control unit 128, and the memory unit 129.

[0041] The memory unit 128b is a storage device having memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory). The memory unit 128b has a smaller storage capacity than the memory unit 129. The memory unit 128b is a memory used to store control data during production operation and software such as the component mounting program Mp. The control data includes a storage activation condition C1 and a storage inactivation condition C2, which will be described later. The component mounting program Mp is a program for performing the mounting process of the component E to be mounted on the board P1. As such, the memory unit 128b is not a dedicated storage medium for storing the component image G1 and the captured image when performing the board recognition process. The detailed configuration of the control unit 128 will be described later.

[0042] The storage unit 129 is a non-volatile large-capacity storage medium such as an SSD (Solid State Drive) or an HDD (Hard Disk Drive). The storage unit 129 is provided separately from the storage unit 128b and a storage unit 22 of the server 2, which will be described later.

[0043] The storage unit 129 is a storage unit for temporarily storing the component image G1, the saved image G2 included in the component image G1, and the captured image when performing the board recognition process. In this way, the storage unit 129 is configured to temporarily store the saved image G2 transmitted from the component mounting device 12 to the server 2 via the network. The saved image G2 is the component image G1 that is set by the control unit 128 to be stored in the storage unit 22 of the server 2.

[0044] The control unit 128 is configured to perform control to store the component image G1 as the saved image G2 in the storage unit 129 based on the fact that the component image G1 satisfies the saved image G2. The control unit 128 is configured to perform control to transmit the saved image G2 from the component mounting apparatus 12 to the server 2 based on a predetermined timing (for example, after production of all production boards P2 for one day has been completed). Here, the control unit 128 is configured to perform control to transmit the saved image G2 to the server 2 so as to avoid an excessive increase in the processing load on the server 2. In other words, the control unit 128 is configured to temporarily store the saved image G2 in the storage unit 129 and perform control to transmit a predetermined number of the temporarily stored saved images G2 to the server 2 all at once. Note that the data including the image information temporarily stored in the storage unit 129 is periodically deleted.

[0045] The communication unit 1210 is configured to transmit information (data such as the saved image G2) from the component mounting device 12 to the server 2 or the like. The communication unit 1210 is also configured to receive information (data) from other devices such as the server 2.

[0046] (Inspection equipment) 5, inspection device 13 is provided downstream of a plurality of component mounting devices 12. Inspection device 13 has a function of inspecting the appearance of board P1 on which components E are mounted by component mounting device 12. That is, inspection device 13 has an inspection imaging unit 131, a control unit 132, and a memory unit 133.

[0047] The inspection imaging unit 131 captures an inspection image G3 of the component E on the board P1 after the mounting work on which the component E has been mounted. The control unit 132 is configured to control the inspection (recognition) of the component E on the board P1 based on the inspection image G3 of the component E on the board P1 after the mounting work. The control unit 132 has a CPU 132a and a memory unit 132b. The memory unit 132b is a storage device having memories such as ROM and RAM. This allows the inspection device 13 to recognize, for example, the amount of positional deviation of the component E, floating of the component E, etc. Furthermore, the inspection device 13 makes a pass / fail judgment (OK / NG judgment) of the component E on the board P1 based on the recognition result of the component E on the board P1.

[0048] (reflow oven) 1, the reflow furnace 14 has a function of melting the solder by performing a heat treatment to bond the component E to the electrode portion of the substrate P1. The reflow furnace 14 is configured to perform the heat treatment while transporting the substrate P1 on the lane.

[0049] (Inspection equipment) The inspection device 15 is provided downstream of the reflow furnace 14. The inspection device 15 has a function of inspecting the appearance of the board P1 after the heat treatment in the reflow furnace 14 has been performed.

[0050] (server) The server 2 is a management computer for managing information transmitted from a plurality of component mounting devices 12, information input by an operator, etc. As shown in Fig. 4, the server 2 is configured to acquire and store a saved image G2 as a component image G1 of a component E captured by the component imaging unit 126 (see Fig. 2).

[0051] Specifically, the server 2 includes a CPU 21, a storage unit 22, and a communication unit 23. The storage unit 22 stores information (such as saved images G2) transmitted from a plurality of component mounting devices 12, information input by an operator, and the like.

[0052] The communication unit 23 is configured to receive information (data) from other devices such as the component mounting device 12 and the inspection device 13. The communication unit 23 is configured to transmit information (data) from the server 2 to the component mounting device 12, the inspection device 13, etc.

[0053] (Control unit) A detailed configuration relating to the control of the control unit 128 of this embodiment will be described below.

[0054] 4, the control unit 128 is configured to acquire the saved image G2 in the storage unit 22 of the server 2. Here, the control unit 128 is configured to perform control to switch between enabling and disabling saving of the component image G1 in the storage unit 22 of the server 2, in order to reduce the number of component images G1 saved in the storage unit 22 of the server 2.

[0055] Specifically, the control unit 128 is configured to perform control to enable a setting to save the component image G1 as a saved image G2 based on whether the save enablement condition C1 is satisfied. The save enablement condition C1 is a condition that enables a setting to save the component image G1 of the component E, captured by the component imaging unit 126 or the like, in the storage unit 22 of the server 2. That is, the control unit 128 is configured to perform control to set identification information indicating that the component image G1 is to be saved as a saved image G2 in information related to the component image G1 based on whether the save enablement condition C1 is satisfied. Here, the saved image G2 is the component image G1 corresponding to the component type of the component E that satisfies the save enablement condition C1.

[0056] Furthermore, the control unit 128 is configured to perform control to disable the setting for saving the component image G1 as a saved image G2, based on whether the save invalidation condition C2 is satisfied. The save invalidation condition C2 is a condition for disabling the setting for saving the component image G1 in the storage unit 22 of the server 2. The save invalidation condition C2 is set in correspondence with the save validation condition C1. That is, the control unit 128 is configured to perform control to stop setting the above-mentioned identification information, based on whether the save invalidation condition C2 is satisfied.

[0057] 6, the storage validation condition C1 includes a pickup rate condition C11, a recognition rate condition C12, a defective inspection condition C13, a first-product condition C14, a part replacement condition C15, a part lot condition C16, a part return condition C17, a part drop condition C18, and a maintenance condition C19. Each of the pickup rate condition C11 and the recognition rate condition C12 is an example of a "first validation condition" in the claims. Each of the first-product condition C14, the part replacement condition C15, the part lot condition C16, the part return condition C17, the part drop condition C18, and the maintenance condition C19 is an example of a "second validation condition" in the claims.

[0058] The storage invalidation condition C2 has a first invalidation condition C21 and a second invalidation condition C22. The first invalidation condition C21 is a condition set corresponding to the pickup rate condition C11, the recognition rate condition C12, and the inspection failure condition C13. The second invalidation condition C22 is a condition set corresponding to the first product condition C14, the part replacement condition C15, the part lot condition C16, the part return condition C17, the part drop condition C18, and the maintenance management condition C19.

[0059] <Adsorption rate conditions> 7, the pickup rate condition C11 is a condition based on an index for acquiring defects related to the mounting of component E. In other words, the pickup rate condition C11 is a condition for the pickup rate, which is an index based on the number of times that nozzle N has failed to pick up component E. The pickup rate condition C11 is a condition that causes the control unit 128 to start control to set component image G1 as saved image G2 when the pickup rate becomes equal to or less than threshold value Th1. Saved image G2 is component image G1 that corresponds to the component type of component E whose pickup rate becomes equal to or less than threshold value Th1.

[0060] Here, the pickup rate is a numerical value obtained by dividing the number of times component E was successfully picked up by the number of times component E was attempted to be picked up. Success in picking up component E indicates, for example, when the negative pressure applied to nozzle N when picking up component E increases to or exceeds a predetermined value. Failure in picking up component E indicates, for example, when the negative pressure applied to nozzle N when picking up component E does not increase to or exceeds a predetermined value.

[0061] The control unit 128 is configured to perform control to store the component image G1 corresponding to the pickup rate condition C11 as the saved image G2 based on whether the pickup rate condition C11 is satisfied. That is, from the time T1 in FIG. 7 when the pickup rate becomes equal to or lower than Th1, the component image G1 captured by the component imaging unit 126 is set as the saved image G2.

[0062] The first invalidation condition C21 is a condition for invalidating the setting of storing the component image G1 corresponding to the pickup rate condition C11 as the saved image G2 in the storage unit 22 based on the fact that the index indicates that the defective state related to the mounting of the component E has been resolved. In other words, the first invalidation condition C21 is a condition for stopping the control of the control unit 128 to set the component image G1 as the saved image G2 based on the fact that the pickup rate has become equal to or greater than the threshold value Th1.

[0063] The control unit 128 is configured to perform control to disable the setting of saving the component image G1 as the saved image G2 when the first invalidation condition C21 is satisfied. That is, from the time T2 in FIG. 7 when the suction rate has recovered to Th1 or higher, the component image G1 captured by the component imaging unit 126 is no longer set as the saved image G2.

[0064] Here, in the pickup rate condition C11, all component images G1 corresponding to the component type of the component E that satisfies the pickup rate condition C11 are set as saved images G2 until the first invalidation condition C21 is satisfied.

[0065] <Recognition rate conditions> 8, the recognition rate condition C12 is a condition based on an index for acquiring defects related to the mounting of component E. In other words, the recognition rate condition C12 is a condition for the recognition rate, which is an index based on the number of times that component E is recognized incorrectly based on component image G1 captured by component imaging unit 126. The recognition rate condition C12 is a condition that causes control unit 128 to start control to set component image G1 as saved image G2 when the recognition rate becomes equal to or less than threshold value Th2. Saved image G2 is component image G1 that corresponds to the component type of component E whose recognition rate becomes equal to or less than threshold value Th2.

[0066] Here, the recognition rate is a numerical value obtained by dividing the number of times component E was successfully recognized by the number of times recognition of component E was attempted. Successful recognition of component E refers to, for example, a case where, after nozzle N picked up component E, component E did not fall off nozzle N before reaching the Z1 direction side of component imaging unit 126, and therefore component imaging unit 126 was able to capture the component. Failure in recognition of component E refers to, for example, a case where, after nozzle N picked up component E, component E fell off nozzle N before reaching the Z1 direction side of component imaging unit 126, and therefore component imaging unit 126 was unable to capture the component.

[0067] The control unit 128 is configured to perform control to store the component image G1 corresponding to the recognition rate condition C12 as the saved image G2 based on whether the recognition rate condition C12 is satisfied. That is, from the time T3 in Fig. 8 when the recognition rate becomes equal to or lower than Th2, the component image G1 captured by the component imaging unit 126 is set as the saved image G2.

[0068] The first invalidation condition C21 is a condition for invalidating the setting of saving the component image G1 that corresponds to the recognition rate condition C12 as the saved image G2 in the storage unit 22 based on the fact that the defective state related to the mounting of the component E in the index has been resolved. In other words, the first invalidation condition C21 is a condition for stopping the control of the control unit 128 to set the component image G1 as the saved image G2 based on the fact that the recognition rate has become equal to or greater than the threshold value Th2.

[0069] The control unit 128 is configured to perform control to invalidate the setting of saving the component image G1 as the saved image G2 when the first invalidation condition C21 is satisfied. That is, from the time T4 in FIG. 8 when the suction rate has recovered to Th2 or higher, the component image G1 captured by the component imaging unit 126 is no longer set as the saved image G2.

[0070] Here, under the recognition rate condition C12, all component images G1 corresponding to the component type of the component E that satisfies the recognition rate condition C12 are set as saved images G2 until the first invalidation condition C21 is satisfied.

[0071] <Inspection failure conditions> As shown in FIG. 9 , the inspection failure condition C13 is a condition based on an index for detecting a defect related to the mounting of component E. That is, the inspection failure condition C13 is a condition based on the defect detection result of the inspection device 13 detecting a mounting failure of component E on the board P1. The defect detection result is a detection result determined based on whether an index representing the amount of misalignment of component E is within a predetermined range based on the inspection image G3 of component E on the board P1 after the mounting operation. The defect detection result is a result obtained when the amount of misalignment of component E from the ideal placement position of component E mounted on the board P1 is outside the predetermined range. In this way, the inspection failure condition C13 is based on the index. The inspection failure condition C13 is a condition that, based on the acquisition of the defect detection result from the inspection device 13, starts control to cause the control unit 128 to set component image G1 as a saved image G2. The saved image G2 is a component image G1 corresponding to the component type of component E for which the index representing the amount of misalignment of component E is outside the predetermined range.

[0072] The control unit 128 is configured to select a component image G1 to be sent to the memory unit 22 of the server 2 and stored in the server 2 from the component images G1 stored in the memory unit 129 based on the inspection defect condition C13, and to control the storage of the selected component image G1 as a saved image G2.

[0073] The first invalidation condition C21 is a condition for invalidating the setting of saving the component image G1 corresponding to the defective inspection condition C13 as the saved image G2 in the storage unit 22 based on the fact that the defective state related to the mounting of the component E in the index has been resolved. In other words, the first invalidation condition C21 is a condition for stopping the control of the control unit 128 to set the component image G1 as the saved image G2 based on the fact that the amount of positional deviation of the component E, which is the index, has fallen within a predetermined range.

[0074] The control unit 128 is configured to perform control to invalidate the setting for saving the part image G1 as the saved image G2, based on whether the first invalidation condition C21 is satisfied.

[0075] Here, under the inspection rejection condition C13, all component images G1 corresponding to the component type of the component E that falls under the inspection rejection condition C13 are set as saved images G2 until the first invalidation condition C21 is satisfied.

[0076] <First-product conditions> 10, the first-product condition C14 is a condition based on an expected phenomenon in which a defect in the mounting of the component E is predicted. In other words, the first-product condition C14 is a condition that there is a component E as an initial product that has never been mounted on the board P1. Here, for the component E as an initial product that has never been mounted on the board P1, there is a high possibility that poor pickup, poor recognition, and poor mounting will occur due to the fact that it has never been mounted, so the component image G1 is saved in the memory unit 22 as the saved image G2.

[0077] The history of the component E mounted on the board P1 is stored, for example, as history information H in the storage unit 128b of the component mounting apparatus 12. The first-product condition C14 is a condition that causes the control unit 128 to start control to set the component image G1 as the saved image G2 based on the start of production of a production board P2 that is produced by mounting a component E that is not included in the history information H saved in the storage unit 128b of the component mounting apparatus 12. The saved image G2 is the component image G1 that corresponds to the component type of the component E that is an initial product that has no history of being mounted on the board P1.

[0078] Here, the part E as the initial product indicates that, for example, when the part names of the first part, the second part, and the third part are registered in the history information H, the part E has the part name of the fourth part.

[0079] The control unit 128 is configured to perform control to store the component image G1 corresponding to the first-item condition C14 as a stored image G2 based on whether the first-item condition C14 is satisfied.

[0080] The second invalidation condition C22 corresponds to the first product condition C14, and is a condition for invalidating the setting of saving the component image G1 that satisfies the first product condition C14 as the saved image G2 in the storage unit 22 based on the fact that the number of saved images G2 has reached a predetermined number after enabling the setting of saving the component image G1 as the saved image G2 based on the first product condition C14. In other words, the second invalidation condition C22 is a condition for stopping the control of the control unit 128 to set the component image G1 as the saved image G2 based on the fact that the number of saved images G2 counted after the first product condition C14 has been satisfied has reached a predetermined number.

[0081] The control unit 128 is configured to perform control to invalidate the setting for saving the part image G1 as the saved image G2 based on the second invalidation condition C22 being satisfied.

[0082] <Parts replacement conditions> The component replacement condition C15 is a condition based on an expected event that predicts a defect in the mounting of the component E. In other words, the component replacement condition C15 is a condition that the component E has been replaced. Here, with regard to the replacement of the component E, since there is a high possibility that a pickup defect, a recognition defect, a mounting defect, etc. will occur after the replacement of the component E, the component image G1 is stored in the storage unit 22 as a saved image G2.

[0083] Component E is replaced when the component E stored in the component supply tape wound on the reel attached to tape feeder 121a runs out. To replace component E, an operator reads the barcode attached to a new reel and attaches tape feeder 121a with the new reel attached to feeder arrangement section 121. Component replacement condition C15 is a condition that, based on the tape feeder 121a with the new reel attached being attached to feeder arrangement section 121, causes control section 128 to start control to set component image G1 as saved image G2. Saved image G2 is component image G1 that corresponds to the component type of component E stored in the new reel of tape feeder 121a for which replacement has been performed.

[0084] The control unit 128 is configured to perform control to store the part image G1 corresponding to the part replacement condition C15 as a saved image G2 based on whether the part replacement condition C15 is satisfied.

[0085] The second invalidation condition C22 corresponds to the part replacement condition C15, and is a condition for invalidating the setting of saving the part image G1 corresponding to the part replacement condition C15 as the saved image G2 in the storage unit 22 based on the fact that the number of saved images G2 has reached a predetermined number after enabling the setting of saving the part image G1 as the saved image G2 based on the part replacement condition C15. In other words, the second invalidation condition C22 is a condition for stopping the control of the control unit 128 to set the part image G1 as the saved image G2 based on the fact that the number of saved images G2 counted after the part replacement condition C15 has been satisfied has reached a predetermined number.

[0086] The control unit 128 is configured to perform control to invalidate the setting for saving the part image G1 as the saved image G2 based on the second invalidation condition C22 being satisfied.

[0087] <Parts lot conditions> 12, component lot condition C16 is a condition based on an expected event that predicts a defect in the mounting of component E. In other words, component lot condition C16 is a condition that the component lot of component E has been changed. Here, with regard to the change of component lot for component E, since there is a high possibility that pickup failure, recognition failure, mounting failure, etc. will occur after the change of component lot for component E, component image G1 is saved in storage unit 22 as saved image G2.

[0088] The component lot is stored as component lot number information L in the memory unit 128b of the component mounting device 12, for example. The component lot number information L is the same number when the components are of the same type and have the same manufacturing date. The component lot number information L is different numbers when the components are of the same type but have different manufacturing dates. The component lot condition C16 is a condition that causes the control unit 128 to start control to set the component image G1 as the saved image G2 based on the change in the component lot number information L. The saved image G2 is the component image G1 that corresponds to the component type of the component E whose component lot has been changed.

[0089] The control unit 128 is configured to perform control to store the component image G1 corresponding to the component lot condition C16 as a stored image G2 based on whether the component lot condition C16 is satisfied.

[0090] The second invalidation condition C22 corresponds to the part lot condition C16, and is a condition for invalidating the setting of saving the part image G1 corresponding to the part lot condition C16 as the saved image G2 in the storage unit 22 based on the fact that the number of saved images G2 has reached a predetermined number after enabling the setting of saving the part image G1 as the saved image G2 based on the part lot condition C16. In other words, the second invalidation condition C22 is a condition for stopping the control of the control unit 128 to set the part image G1 as the saved image G2 based on the fact that the number of saved images G2 counted after the part lot condition C16 has been satisfied has reached a predetermined number.

[0091] The control unit 128 is configured to perform control to invalidate the setting for saving the part image G1 as the saved image G2 based on the second invalidation condition C22 being satisfied.

[0092] <Conditions for taking back parts> 13, the component take-home condition C17 is a condition based on a predicted event that predicts a defect in the mounting of the component E. In other words, the component take-home condition C17 is a condition that an error (hereinafter referred to as a component take-home error) has occurred in which the component E is moved while remaining attached to the nozzle N without being mounted on the board P1. Here, with regard to the component take-home error, since there is a high possibility that the component take-home error will occur again after the component take-home error has occurred, the component image G1 is saved in the storage unit 22 as a saved image G2.

[0093] A component take-home error is an error that is identified when, after component E picked up by nozzle N is imaged by component imaging unit 126 before mounting, the negative pressure of nozzle N remains elevated to a predetermined value or higher after component E is mounted, and component E is present in component image G1 imaged by component imaging unit 126. Component take-home condition C17 is a condition that, based on the identification of a component take-home error, causes control unit 128 to start control of setting component image G1 as saved image G2. Saved image G2 is component image G1 that corresponds to the component type of component E for which the component take-home error occurred.

[0094] The control unit 128 is configured to perform control to store the component image G1 corresponding to the component take-home condition C17 as a stored image G2 based on whether the component take-home condition C17 is satisfied.

[0095] The second invalidation condition C22 corresponds to the component take-home condition C17, and is a condition for invalidating the setting for saving the component image G1 corresponding to the component take-home condition C17 as the saved image G2 in the storage unit 22 based on the fact that the number of saved images G2 has reached a predetermined number after enabling the setting for saving the component image G1 as the saved image G2 based on the component take-home condition C17. In other words, the second invalidation condition C22 is a condition for stopping the control of the control unit 128 to set the component image G1 as the saved image G2 based on the fact that the number of mounted saved images G2 counted after the component take-home condition C17 has been satisfied has reached a predetermined number.

[0096] The control unit 128 is configured to perform control to invalidate the setting for saving the part image G1 as the saved image G2 based on the second invalidation condition C22 being satisfied.

[0097] <Conditions for component drop> 14, the component drop condition C18 is a condition based on a predicted event that predicts a failure in mounting of the component E. In other words, the component drop condition C18 is a condition that an error (hereinafter referred to as a drop error) has occurred in which the component E falls from the nozzle N. Here, regarding the drop error, since there is a high possibility that the drop error will occur again after the drop error has occurred, the component image G1 is saved in the storage unit 22 as the saved image G2.

[0098] A drop error is an error that is identified when a component E is not picked up by the nozzle N when the nozzle N is lowered to mount (mount) the component E at a predetermined mounting position on the board P1 after the component E picked up by the nozzle N is imaged by the component imaging unit 126 before mounting. Whether the component E is not picked up by the nozzle N when the nozzle N is lowered is determined, for example, based on whether the negative pressure of the nozzle N falls below a predetermined value when the nozzle N is lowered, or whether the component E is not present in the captured image G4 (e.g., captured by a component side imaging unit, etc.). The component drop condition C18 is a condition that, based on the identification of a drop error, causes the control unit 128 to start control to set the component image G1 as the saved image G2. The saved image G2 is the component image G1 that corresponds to the component type of the component E for which the drop error occurred.

[0099] The control unit 128 is configured to perform control to store the component image G1 corresponding to the component drop condition C18 as a saved image G2 based on whether the component drop condition C18 is satisfied.

[0100] The second invalidation condition C22 corresponds to the component drop condition C18, and is a condition for invalidating the setting of saving the component image G1 corresponding to the component drop condition C18 as the saved image G2 in the storage unit 22 based on the fact that the number of saved images G2 has reached a predetermined number after enabling the setting of saving the component image G1 as the saved image G2 based on the component drop condition C18. In other words, the second invalidation condition C22 is a condition for stopping the control of the control unit 128 to set the component image G1 as the saved image G2 based on the fact that the number of saved images G2 counted after the component drop condition C18 has been satisfied has reached a predetermined number.

[0101] The control unit 128 is configured to perform control to invalidate the setting for saving the part image G1 as the saved image G2 based on the second invalidation condition C22 being satisfied.

[0102] <Maintenance management conditions> 15, the maintenance condition C19 is a condition based on a predicted event that predicts a defect related to the mounting of component E. In other words, the maintenance condition C19 is a condition that maintenance has been completed. Here, regarding the completion of maintenance, after maintenance of the devices that make up component mounting apparatus 12, there is a high possibility that a defect will occur due to the maintained device, so component image G1 is stored in storage unit 22 as saved image G2.

[0103] The maintenance management is, for example, the replacement of nozzle N. The replacement of nozzle N is stored in the memory unit 22 of the server 2 as replacement information Ch for nozzle N. The replacement information Ch for nozzle N is identified, for example, by resetting the number of mounting times for nozzle N to 0 or by recording information that nozzle N has been replaced. The maintenance management condition C19 is a condition that, based on the completion of maintenance management, causes the control unit 128 to start control to set component image G1 as saved image G2. The saved image G2 is component image G1 that corresponds to the component type of component E on which work was performed by the device that performed the maintenance management.

[0104] The control unit 128 is configured to perform control to store the component image G1 corresponding to the maintenance management condition C19 as a stored image G2 based on whether the maintenance management condition C19 is satisfied.

[0105] The second invalidation condition C22 corresponds to the maintenance management condition C19, and is a condition for invalidating the setting of saving the component image G1 corresponding to the maintenance management condition C19 as the saved image G2 in the storage unit 22 based on the fact that the number of saved images G2 has reached a predetermined number after enabling the setting of saving the component image G1 as the saved image G2 based on the maintenance management condition C19. In other words, the second invalidation condition C22 is a condition for stopping the control of the control unit 128 to set the component image G1 as the saved image G2 based on the fact that the number of saved images G2 counted after the maintenance management condition C19 has been satisfied has reached a predetermined number.

[0106] The control unit 128 is configured to perform control to invalidate the setting for saving the part image G1 as the saved image G2 based on the second invalidation condition C22 being satisfied.

[0107] (Image save setting change process) Hereinafter, with reference to FIGS. 16 to 19, an image storage setting change process for setting whether or not the part image G1 is to be stored in the server 2 as a storage image G2 by the control unit 128 will be described.

[0108] 16, image storage is enabled in step S1, image storage is disabled in step S2, and then the image storage setting change process is completed.

[0109] The image storage validation process, which is a subroutine of the image storage setting change process, will be described with reference to FIGS.

[0110] In step S101, it is determined whether or not the adsorption rate condition C11 is satisfied. If the adsorption rate condition C11 is satisfied, the process proceeds to step S109; if the adsorption rate condition C11 is not satisfied, the process proceeds to step S102. In step S102, it is determined whether or not the recognition rate condition C12 is satisfied. If the recognition rate condition C12 is satisfied, the process proceeds to step S109; if the recognition rate condition C12 is satisfied, the process proceeds to step S103. In step S103, it is determined whether or not the inspection failure condition C13 is satisfied. If the inspection failure condition C13 is satisfied, the process proceeds to step S109; if the inspection failure condition C13 is not satisfied, the process proceeds to step S104.

[0111] In step S104, it is determined whether the first product condition C14 is satisfied. If the first product condition C14 is satisfied, the process proceeds from point B in FIG. 17 via point B in FIG. 18 to step S112; if the first product condition C14 is not satisfied, the process proceeds to step S105. In step S105, it is determined whether the part replacement condition C15 is satisfied. If the part replacement condition C15 is satisfied, the process proceeds from point B in FIG. 17 via point B in FIG. 18 to step S112; if the part replacement condition C15 is not satisfied, the process proceeds to step S106. In step S106, it is determined whether the part lot condition C16 is satisfied. If the part lot condition C16 is satisfied, the process proceeds from point B in FIG. 17 via point B in FIG. 18 to step S112; if the part lot condition C16 is not satisfied, the process proceeds to step S107.

[0112] In step S107, it is determined whether the component take-home condition C17 is satisfied. If the component take-home condition C17 is satisfied, the process proceeds from point B in FIG. 17 via point B in FIG. 18 to step S112; if the component take-home condition C17 is not satisfied, the process proceeds to step S108. In step S108, it is determined whether the component drop condition C18 is satisfied. If the component drop condition C18 is satisfied, the process proceeds from point B in FIG. 17 via point B in FIG. 18 to step S112; if the component drop condition C18 is not satisfied, the process proceeds from point A in FIG. 17 via point A in FIG. 18 to step S111.

[0113] In step S109, all acquired component images G1 are set to be saved as saved images G2 on the server 2. In step S110, index monitoring for monitoring any one of the indexes of pickup rate, recognition rate, and positional deviation amount of component E is stored in the memory unit 128b, and then the image saving activation process is terminated via point C in Figure 17 and point C in Figure 18.

[0114] 18, in step S111, it is determined whether or not the maintenance management condition C19 is satisfied. If the maintenance management condition C19 is satisfied, the process proceeds to step S112, and if the maintenance management condition C19 is not satisfied, the image storage validation process ends.

[0115] In step S112, after the first product condition C14, part replacement condition C15, part lot condition C16, part return condition C17, part drop condition C18, or maintenance management condition C19 is satisfied, a predetermined number of images G2 are set to be saved. In step S113, predicted event monitoring that monitors any of the predicted events of the first product condition C14, part replacement condition C15, part lot condition C16, part return condition C17, part drop condition C18, and maintenance management condition C19 is stored in memory unit 128b, and then the image saving activation process is terminated.

[0116] Referring to FIG. 19, the image storage invalidation process, which is a subroutine of the image storage setting change process, will be described.

[0117] In step S201, it is determined whether or not the part is E whose indicator is being monitored. If it is E whose indicator is being monitored, the process proceeds to step S202, and if it is not E whose indicator is being monitored, the process proceeds to step S204. In step S202, it is determined whether or not the indicator has improved. If the indicator has improved, image storage is disabled in step S203, and then the image storage disablement process is terminated. If the indicator has not improved, the image storage disablement process is terminated without disabling image storage.

[0118] In step S204, it is determined whether or not the part is E that is currently being monitored for a predicted event. If it is E that is currently being monitored for a predicted event, the process proceeds to step S205; if it is not E that is currently being monitored for a predicted event, the image storage disable process ends without disabling image storage. In step S205, it is determined whether or not a predetermined number of saved images G2 have been saved. If the predetermined number of saved images G2 have been saved, image storage is disabled in step S203, and the image storage disable process ends. If the predetermined number of saved images G2 have not been saved, the image storage disable process ends without disabling image storage.

[0119] (Effects of this embodiment) In this embodiment, the following effects can be obtained.

[0120] In this embodiment, as described above, the component mounting apparatus 12 includes the control unit 128 configured to enable a setting to save the component image G1 of the component E captured by the component imaging unit 126 as a saved image G2 in the storage unit 22 based on whether the storage enablement condition C1 is satisfied, which enables a setting to save the component image G1 of the component E captured by the component imaging unit 126 in the storage unit 22. This prevents the component image G1 captured by the component imaging unit 126 from being saved in the storage unit 22 unless the storage enablement condition C1 is satisfied, thereby suppressing an increase in the storage capacity of the storage unit 22 required for image saving. Furthermore, when the component image G1 needs to be saved in the storage unit 22, the component image G1 can be automatically saved in the storage unit 22 as a saved image G2, making it easy to obtain the component image G1 that needs to be saved in the storage unit 22.

[0121] Furthermore, in this embodiment, as described above, the control unit 128 is configured to perform control to cause the storage unit 22 of the server 2 to acquire the saved image G2. This allows the part images G1 to be narrowed down to the saved image G2 and saved in the storage unit 22 of the server 2, thereby suppressing an increase in the storage capacity required for image storage in the storage unit 22 of the server 2.

[0122] Furthermore, in this embodiment, as described above, the storage validation condition C1 includes a pickup rate condition C11 and a recognition rate condition C12 (first validation condition) based on an index for acquiring a defect related to the mounting of component E. The control unit 128 is configured to perform control to store the component image G1 corresponding to the first validation condition as a saved image G2 in the storage unit 22 based on the satisfaction of the first validation condition. This allows the component image G1 after the index has decreased to the point where the control unit 128 has identified that a defect related to the mounting of component E has occurred to be stored in the storage unit 22 as a saved image G2, thereby allowing images necessary for identifying the cause of the mounting defect to be stored.

[0123] Furthermore, in this embodiment, as described above, the component mounting device 12 is equipped with a head 125a including a nozzle N that picks up a component E to be mounted on the board P1. The component mounting device 12 also includes a component imaging unit 126 that images the component E picked up by the nozzle N. The pickup rate condition C11 (first validation condition) is a pickup rate condition that is an index based on the number of times the nozzle N has failed to pick up the component E. The recognition rate condition C12 (first validation condition) is a pickup rate condition that is an index based on the number of times the nozzle N has failed to pick up the component E. This allows the component image G1 after at least one of the pickup rate and the recognition rate has decreased to be saved in the storage unit 22 as a saved image G2, making it possible to save images necessary for identifying the cause of at least one of the pickup failure and the recognition failure.

[0124] Furthermore, in this embodiment, as described above, the control unit 128 is configured to perform control to disable the setting for saving the component image G1 as a saved image G2 in the storage unit 22 based on the satisfaction of the first disablement condition C21, which disables the setting for saving the component image G1 based on the fact that the defective state related to the mounting of the component E has been resolved in the index. This allows the setting for saving the component image G1 to be disabled at an appropriate time based on the first disablement condition C21, thereby suppressing an increase in the number of saved images G2 required to identify defects related to the mounting of the component E.

[0125] Furthermore, in this embodiment, as described above, the storage validation conditions C1 include a first-item condition C14, a component replacement condition C15, a component lot condition C16, a component take-home condition C17, a component drop condition C18, and a maintenance management condition C19 (second validation conditions) based on predicted events that predict defects related to the mounting of component E. The control unit 128 is configured to perform control to store a component image G1 corresponding to the second validation condition as a saved image G2 in the storage unit 22 based on the second validation condition being satisfied. This allows the component image G1 after a predicted defect to be stored in the storage unit 22 as the saved image G2, making it possible to identify signs of a mounting defect before it occurs from the saved image G2 stored in the storage unit 22.

[0126] Furthermore, in this embodiment, as described above, the component mounting device 12 is equipped with a head 125a including a nozzle N that picks up the component E to be mounted on the board P1. The second validating conditions are a first-product condition C14, a component replacement condition C15, a component lot condition C16, a component take-home condition C17, a component drop condition C18, and a maintenance management condition C19. This allows the component image G1 taken after a condition under which a defect in the component E is likely to occur to be reliably saved as a saved image G2 in the storage unit 22, thereby ensuring that images necessary for identifying the cause of the defect in the component E are saved.

[0127] Furthermore, in this embodiment, as described above, the control unit 128 is configured to enable the setting to save the component image G1 as the saved image G2 based on the first product condition C14, the component replacement condition C15, the component lot condition C16, the component take-home condition C17, the component drop condition C18, or the maintenance management condition C19 (second enabling condition), and then disable the setting to save the saved image G2 in the storage unit 22 based on the satisfaction of the second disabling condition C22 that disables the setting to save the component image G1 based on the number of saved images G2 reaching a predetermined number. This allows the setting to save the component image G1 based on the second disabling condition C22 to be disabled at an appropriate time, thereby preventing an increase in the number of saved images G2 required to identify defects related to the mounting of the component E.

[0128] Furthermore, in this embodiment, as described above, the component mounting apparatus 12 includes a storage unit 129 that is provided separately from the storage unit 22 and that temporarily stores the component image G1. The control unit 128 is configured to perform control to select a component image G1 to be transmitted to the storage unit 22 of the server 2 and stored in the server 2 from the component images G1 stored in the storage unit 129 and stored in the server 2, based on the storage activation condition C1, and store the selected component image G1 as a stored image G2. This allows multiple stored images G2 to be stored in the storage unit 129 and then stored in the server 2, compared to when a component image G1 is stored in the storage unit 22 of the server 2 every time an image is captured by the component imaging unit 126, and therefore reduces the amount of processing required to store the stored image G2 in the storage unit 22 of the server 2.

[0129] Furthermore, in this embodiment, as described above, the component mounting device 12 is provided with a control unit 128 configured to enable a setting to save the component image G1 as a saved image G2 in the storage unit 22 of the server 2 based on satisfaction of the save enablement condition C1 that enables the setting to save the component image G1 in the storage unit 22 of the server 2. This prevents the component image G1 captured by the component imaging unit 126 from being saved in the storage unit 22 unless the save enablement condition C1 is satisfied, thereby providing a component mounting system that can suppress an increase in the storage capacity of the storage unit 22 required for image saving.

[0130] Furthermore, in this embodiment, as described above, the component mounting system 100 includes the inspection device 13 disposed downstream of the component mounting device 12, and a storage unit 129 that is provided separately from the storage unit of the server 2 and that temporarily stores the component image G1. The storage activation condition C1 is an inspection failure condition C13 based on a defect detection result in which the inspection device 13 detects a mounting failure of the component E on the board P1. The control unit 128 is configured to perform control to select, based on the inspection failure condition C13, a component image G1 to be sent to the server 2 and stored in the server 2 from the component images G1 stored in the storage unit 129, and store the selected component image G1 in the server 2 as a saved image G2 in the storage unit 22 of the server 2. This allows the component image G1 after a component mounting failure has occurred to be stored as a saved image G2 in the storage unit 22 of the server 2, thereby saving images necessary for identifying the cause of the mounting failure of the component E.

[0131] [Variations] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims rather than the above description of the embodiments, and further includes all modifications (variations) within the meaning and scope of the claims.

[0132] For example, in the above embodiment, the "first validation condition" in the claims is the pick-up rate condition C11, the recognition rate condition C12, and the inspection failure condition C13, but the present invention is not limited to this. In the present invention, the first validation condition may include at least one of the pick-up rate condition, the recognition rate condition, and the inspection failure condition, or may include other conditions based on the index.

[0133] In the above embodiment, the first product condition C14, the part replacement condition C15, the part lot condition C16, the part return condition C17, the part drop condition C18, and the maintenance management condition C19 are described as the "second validation conditions" in the claims, but the present invention is not limited to this. In the present invention, the second validation conditions may include at least one of the first product condition, the part replacement condition, the part lot condition, the part return condition, the part drop condition, and the maintenance management condition, and may also include other conditions based on predicted events.

[0134] In the above embodiment, the control unit 128 is configured to control the storage unit 22 of the server 2 to acquire the saved image G2, but the present invention is not limited to this. In the present invention, the control unit may cause the saved image to be acquired by an external storage device other than the server, or may store the saved image in the storage unit of the control unit.

[0135] In the above embodiment, the first invalidation condition C21 of the defective inspection condition C13 is an example of a condition that causes the control unit 128 to stop control of setting the component image G1 as the saved image G2 based on the amount of misalignment of the component E, which is the index, falling within a predetermined range, but the present invention is not limited to this. In the present invention, the first invalidation condition of the defective inspection condition may be a condition that causes the control unit to stop control of setting the component image as the saved image when no defects are detected for a certain period of time after the defect detection result is obtained, or when the frequency of defects decreases after the defect detection result is obtained.

[0136] In the above embodiment, the component mounting device 12 has the storage unit 129 (temporary storage unit), but the present invention is not limited to this. In the present invention, the component mounting device does not need to have a temporary storage unit. In this case, the saved image is sent directly to the server.

[0137] In the above embodiment, the component image G1 is an image captured by the component imaging unit 126 (imaging unit), but the present invention is not limited to this. In the present invention, the component image may be an image of a component captured by an imaging unit other than the component imaging unit (such as a component side imaging unit or a board imaging unit).

[0138] In the above embodiment, the storage activation condition C1 and the storage invalidation condition C2 are set for each component type of component E, but the present invention is not limited to this. In the present invention, the storage activation condition and the storage invalidation condition may be set for each nozzle. In this case, an image of a component picked up by a nozzle replaced for maintenance may be saved as a saved image. In addition, the storage activation condition and the storage invalidation condition may be set for each tape feeder. In this case, an image of a component supplied from a replaced tape feeder may be saved as a saved image.

[0139] In the above embodiment, the second invalidation condition C22 is an example of a condition that causes the control unit 128 to stop control of setting the component image G1 as the saved image G2 based on the fact that the number of saved images G2 counted after any one of the first product condition C14, the part replacement condition C15, the part lot condition C16, the part return condition C17, the part drop condition C18, and the maintenance management condition C19 (second validation condition) has reached a predetermined number. However, the present invention is not limited to this. In the present invention, the second invalidation condition may be to save the saved image in the server once every predetermined number of mounting attempts within a certain number of mounting attempts after the second validation condition has been satisfied. Alternatively, the frequency of saving the saved image in the server may be gradually reduced.

[0140] Furthermore, in the above embodiment, under the pickup rate condition C11 (the recognition rate condition C12 and the inspection failure condition C13: the first validation condition), all component images G1 corresponding to the component type of component E that satisfy the pickup rate condition C11 (the recognition rate condition C12 and the inspection failure condition C13: the first validation condition) are set as saved images G2 until the first invalidation condition C21 is satisfied. However, the present invention is not limited to this. Under the first validation condition, under the present invention, saved images may be saved to the server once every predetermined number of mountings within a certain number of mountings after the first invalidation condition is satisfied. Furthermore, the frequency at which saved images are saved to the server may be gradually reduced.

[0141] In the above embodiment, the second invalidation condition C22 is an example in which a predetermined number of saved images G2 are saved after either the component take-home condition C17 or the component drop condition C18 is satisfied, but the present invention is not limited to this. In the present invention, the second invalidation condition may be such that, at the time of the first component mounting after either the component drop condition or the maintenance management condition is satisfied, a video of the component mounting is saved in the server instead of saved images.

[0142] In the above embodiment, the pickup rate is an example obtained by dividing the number of times component E was successfully picked up by the number of times pickup of component E was attempted, but the present invention is not limited to this. In the present invention, the pickup rate may be an example obtained by dividing the number of times a component was unsuccessfully picked up by the number of times pickup of the component was attempted.

[0143] In the above embodiment, the recognition rate is an example obtained by dividing the number of times component E was successfully recognized by the number of times recognition of component E was attempted, but the present invention is not limited to this. In the present invention, the recognition rate may be an example obtained by dividing the number of times component recognition failed by the number of times recognition of component E was attempted.

[0144] In the above embodiment, for convenience of explanation, the control processing of the control unit 128 is explained using a flow-driven flowchart in which processing is performed sequentially according to a processing flow, but the present invention is not limited to this. In the present invention, the control processing of the control unit may be performed by event-driven processing in which processing is performed on an event-by-event basis. In this case, the control processing may be performed completely event-driven, or may be performed in a combination of event-driven and flow-driven. [Explanation of symbols]
