[0001] The present disclosure generally relates to a mounting system, a mounting control method, a mounting device, and a management system, and more particularly to a mounting system that mounts components on a board, a mounting control method, a mounting device, and a management system.

[0002] Conventionally, there has been known an electronic component mounting device (mounting system) that includes a feeder base (feeder) that supplies components stored in a storage tape to a component removal position, and a head unit (mounting head) that sucks the components from the component removal position (see Patent Document 1).

[0003] In Patent Document 1, a control device provided in an electronic component mounting device controls the storage tape feed drive source to decelerate when feeding the storage tape when the connecting tape (connecting portion) connecting the storage tapes is in the component removal position.

[0013] (Embodiment) Hereinafter, a mounting system, a mounting control method, and a mounting device and management system provided in the mounting system according to this embodiment will be described with reference to the drawings. The drawings referred to in the following embodiments are schematic diagrams, and the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensions, and the size ratios and thickness ratios between the components do not necessarily reflect the actual dimensional ratios.

[0014] (1) Overview The mounting system 1 according to the embodiment is an apparatus for mounting (attaching) a component 30 captured by a capture unit 122 onto a substrate 40. The mounting system 1 is used in the manufacturing of various products such as electronic devices and automobiles in facilities such as factories, laboratories, offices, and educational facilities.

[0015] In this embodiment, a case where the mounting system 1 is used in the manufacture of electronic devices in a factory will be described. Typical electronic devices include various circuit boards, such as power supply circuits and control circuits. In the manufacture of these circuit boards, for example, a solder application process, a mounting process, and a soldering process are performed in this order. In the solder application process, cream solder is applied (or printed) to a board (including a printed wiring board). In the mounting process, components (including electronic components) are mounted (attached) to the board. In the soldering process, for example, the board with the mounted components is heated in a reflow furnace to melt the cream solder and perform soldering. In the mounting process, the mounting system 1 performs the following operations: causing the capture unit 122 to capture the component 30; and mounting (attaching) the component 30 captured by the capture unit 122 to the board 40.

[0016] As described above, the mounting system 1 used to mount components 30 on a substrate 40 includes a mounting apparatus 10 and a management system 20, as shown in FIGS. 1 and 2 . The mounting apparatus 10 includes a communication unit 101, a mounting head 102, a detection unit 103, a control unit 104, a movement unit 105, a transport unit 106, multiple feeders 107, a fixed camera 108, and a base 110. The communication unit 101 is configured to communicate with the management system 20. The transport unit 106 has a pair of conveyor mechanisms 161 extending in the X-axis direction (a direction perpendicular to the plane of FIG. 2 ) on the base 110, and transports the substrate 40 in the X-axis direction to position it in a predetermined mounting space. The multiple feeders 107 include multiple tape feeders attached to a feeder base 12 of a carriage 11 connected to the base 110, lined up in the X-axis direction. Each of the multiple feeders 107 pitch-feeds the storage tape 14 supplied from the reel 13 and supplies the components 30 held (stored) on the storage tape 14 to the component supply port 171. The reel 13 is held by the dolly 11. The fixed camera 108 is attached to a base 110 and captures images of the upward direction. A mounting head 102 and a moving unit 105 are provided on the base 110. In addition, the worker performs splicing work to connect the ends of the storage tape 14 attached to the feeder 107. That is, the worker performs splicing work to connect the end of a new storage tape 14 to the end of the storage tape 14 attached to the feeder 107.

[0017] A pair of support legs (not shown) are installed on the base 110. The pair of support legs are located on both sides of the transport unit 106 in the X-axis direction (the direction perpendicular to the paper surface of FIG. 2 ) and extend in the Y-axis direction. Each of the pair of support legs is provided with a guide rail (Y-axis drive unit 154), and both ends of an axis member (X-axis drive unit 153) that holds the head unit 121 of the mounting head 102 in a state where it can move in the X-axis direction is attached to the pair of guide rails. Each support leg is provided with a Y-axis motor (not shown) of the moving unit 105, and the Y-axis motor moves the axis member and the head unit 121 in the Y-axis direction along the guide rails. Furthermore, the axis member is provided with a guide member extending in the X-axis direction and an X-axis motor (not shown) of the moving unit 105, and the X-axis motor moves the head unit 121 in the X-axis direction along the guide member.

[0018] The mounting head 102 has a capturing unit 122 that can capture the component 30. The capturing unit 122 is, for example, a suction nozzle, and captures the component 30 in a state in which it can be released (i.e., released from the capture). The mounting device 10 of the mounting system 1 lowers the capturing unit 122 so that it approaches the component supply port 171 of the feeder 107, causing the capturing unit 122 to capture the component 30. Furthermore, with the capturing unit 122 capturing the component 30, the mounting device 10 of the mounting system 1 lowers the capturing unit 122 so that it approaches the board 40, thereby mounting (attaching) the component 30 to the board 40.

[0019] As shown in FIG. 1 , a mounting system 1 according to an embodiment includes a mounting apparatus 10 and a management system 20. The mounting apparatus 10 includes a mounting head 102, a feeder 107, and a control unit 104. The mounting head 102 has a capture unit 122 that captures components 30 from a storage tape 14 that stores the components 30, and mounts the components 30 captured by the capture unit 122 on a substrate 40. The feeder 107 supplies the components 30 stored on the storage tape 14 to a capture position where the components 30 will be captured by the mounting head 102. The control unit 104 controls the mounting of the components 30. The management system 20 manages the worker who performed the splicing work of joining the ends of the storage tape 14 attached to the feeder 107. The management system 20 calculates a capture error value for the worker, which is a value related to capture errors that occurred in a predetermined section from the connection portion where the storage tape 14 is joined. The management system 20 transmits capture-related information regarding the feeder 107 corresponding to the worker whose capture error value is equal to or greater than a predetermined value to the mounting device 10. Based on the capture-related information transmitted from the management system 20, the control unit 104 performs a stabilization process, which is a process for improving the stability of the capture operation in which the mounting head 102 captures the component 30.

[0020] According to this configuration, when the capture error value is equal to or greater than a predetermined value, stabilization processing is performed on the corresponding feeder 107. This improves productivity compared to when stabilization processing is always performed. This reduces the occurrence of component suction errors at the connecting portions of the storage tape 14, while also improving productivity.

[0021] (2) Configuration Next, the configuration of the mounting system 1 according to the embodiment will be described with reference to FIGS. 1 and 2. FIG.

[0022] (2.1) Premise In the present embodiment, as an example, a case will be described in which the mounting apparatus 10 of the mounting system 1 is used to mount the component 30 using surface mount technology (SMT). That is, the component 30 is a surface mount device (SMD) that is mounted by being placed on the mounting surface 401 of the substrate 40. However, this example is not limiting, and the mounting apparatus 10 of the mounting system 1 may also be used to mount the component 30 using insertion mount technology (IMT). In this case, the component 30 is an insertion mount component having lead terminals that is mounted on the mounting surface 401 of the substrate 40 by inserting the lead terminals into holes in the substrate 40. That is, in this disclosure, "mounting a component on a substrate" includes placing the component on the mounting surface of the substrate and inserting the lead terminals of the component into holes in the substrate.

[0023] In the following description, three mutually orthogonal axes, the X-axis, the Y-axis, and the Z-axis, are defined as follows: the axes parallel to the surface of the substrate 40 are referred to as the "X-axis" and the "Y-axis," and the axis parallel to the thickness direction of the substrate 40 is referred to as the "Z-axis." Furthermore, one of the two directions along the Z-axis is referred to as the upward direction, and the other as the downward direction. For example, when the capture unit 122 faces the substrate 40, the substrate 40 is positioned below the capture unit 122. The X-axis, the Y-axis, and the Z-axis are all imaginary axes, and the arrows indicating "X," "Y," and "Z" in the drawings are merely used for explanatory purposes and do not represent any physical entities. Furthermore, these directions are not intended to limit the orientation of the mounting device 10 of the mounting system 1 during use.

[0024] In addition, pipes for circulating cooling water, cables for supplying power, and pipes for supplying air pressure (including positive pressure and vacuum) are connected to the mounting device 10, but in this embodiment, these are omitted from the illustration as appropriate.

[0025] (2.2) Mounting Apparatus Next, each component of the mounting apparatus 10 according to the embodiment will be described with reference to FIGS. 1 and 2. FIG.

[0026] The mounting device 10 of the mounting system 1 is a device that captures components and mounts them on a board. As shown in Figures 1 and 2, the mounting device 10 includes a communication unit 101, a mounting head 102, a detection unit 103, a control unit 104, a moving unit 105, a conveying unit 106, multiple feeders 107, a fixed camera 108, and an imaging unit 109. However, the moving unit 105, the conveying unit 106, and the fixed camera 108 are not essential components of the mounting device 10. In other words, all or some of the moving unit 105, the conveying unit 106, and the fixed camera 108 do not have to be included as components of the mounting device 10.

[0027] (2.2.1) Communication Unit The communication unit 101 has a communication interface for communicating with the management system 20. The communication between the communication unit 101 and the management system 20 may be wired communication or wireless communication.

[0028] (2.2.2) Mounting Head The mounting head 102 has a capturing unit 122 that captures components 30 from the storage tape 14 that stores the components 30, and mounts the components 30 captured by the capturing unit 122 on the board 40. Under the control of the control unit 104, the mounting head 102 performs a turning operation, which is an operation of capturing multiple components 30 from multiple feeders 107 and mounting the captured multiple components on the board. The mounting head 102 has at least one capturing unit 122. In this embodiment, the mounting head 102 has one capturing unit 122. The mounting head 102 moves (lowers) the capturing unit 122 so that it approaches the capturing position, and causes the capturing unit 122 to capture the component 30 located at the capturing position. The capturing position (suction position) is an area in the feeder 107 that supplies the components 30 where the component 30 is captured (sucked). In the mounting apparatus 10, the feeder 107 supplies the components 30 to the component supply port 171, and therefore the component supply port 171 corresponds to the capture position.

[0029] Furthermore, with the component 30 captured by the capturing unit 122, the mounting head 102 moves (lowers) the capturing unit 122 so that it approaches the mounting position on the mounting surface 401 of the board 40, and mounts (attaches) the component 30 at the mounting position. The mounting position is the area on the mounting surface 401 of the board 40 where the component 30 is mounted. In the mounting device 10, the pads or lands provided on the mounting surface 401 of the board 40 correspond to the mounting position. In this way, the mounting head 102 holds the capturing unit 122 so that it can move toward the capturing position (component supply port 171) and the mounting position.

[0030] The capturing unit 122 is, for example, a suction nozzle. The capturing unit 122 is controlled by the control unit 104 and is capable of switching between a suction state in which it suctions (holds) the component 30 and a release state in which it releases (releases suction) the component 30. However, the capturing unit 122 is not limited to a suction nozzle, and may be configured to capture (hold) the component 30 by grasping (picking) it, like a robot hand or a mechanical chuck, for example. In other words, "capturing a component" in this disclosure includes both suctioning the component and grasping the component.

[0031] The mounting head 102 operates by receiving air pressure (vacuum) as power when the capturing unit 122 captures the component 30. That is, the mounting head 102 switches the capturing unit 122 between an adsorption state and a release state by opening and closing a valve on the air pressure (vacuum) supply path connected to the capturing unit 122.

[0032] In addition to the capturing portion 122, the mounting head 102 further has a head unit 121 that holds the capturing portion 122. In this embodiment, one capturing portion 122 is attached to one head unit 121. This allows the mounting head 102 to capture (hold) one component 30.

[0033] As an example, the head unit 121 is made of metal and formed in a rectangular parallelepiped shape. The head unit 121 holds the capture unit 122 and the vertical drive unit 152 (see FIG. 1), which will be described later, by assembling the capture unit 122 and the vertical drive unit 152 to the head unit 121. In this embodiment, the capture unit 122 is indirectly held by the head unit 121 via the vertical drive unit 152, in a state in which it can move in the Z-axis direction and the θ direction, which will be described later. Furthermore, the mounting head 102 moves within the X-Y plane by moving the head unit 121 within the X-Y plane using the horizontal drive unit 151 (see FIG. 1), which will be described later. The "X-Y plane" here refers to a plane that includes the X-axis and the Y-axis and is perpendicular to the Z-axis.

[0034] According to the above-described configuration, the mounting head 102 can move (lower) the capturing portion 122 so as to approach the capturing position (component supply port 171), and can cause the component 30 located at the capturing position to be captured by the capturing portion 122. Furthermore, with the component 30 captured (sucked) by the capturing portion 122, the mounting head 102 can move (lower) the capturing portion 122 so as to approach the mounting position on the mounting surface 401 of the board 40, and can mount (attach) the component 30 at the mounting position.

[0035] (2.2.3) Detection Unit The detection unit 103 is a sensor that detects the joint, i.e., the connected portion, of two storage tapes 14 connected by the splicing operation. The detection unit 103 is provided in each of the multiple feeders 107. As shown in FIG. 2 , the detection unit 103 is provided on the reel 13 side of the component supply port 171. The detection unit 103 detects the connected portion of the storage tape 14 at a position before it is captured by the capture unit 122.

[0036] (2.2.4) Imaging Unit The imaging unit 109 is provided in the mounting head 102. The imaging unit 109 images an area including the component supply port 171. That is, the imaging unit 109 images the capture position (component supply port 171). The imaging unit 109 images the component supply port 171 from above. Therefore, the component 30 appears in the image captured by the imaging unit 109. That is, the image captured by the imaging unit 109 includes information about the position of the component 30. In this case, the imaging unit 109 does not capture images all the time, but the start and end of imaging is controlled by the control unit 104.

[0037] (2.2.5) Control Unit The control unit 104 can be realized, for example, by a computer system having one or more processors and one or more memories. That is, the control unit 104 functions as a computer system by having one or more processors execute a program recorded in one or more memories of the computer system. Here, the program is pre-recorded in the memory of the computer system, but it may also be provided via a telecommunications line such as the Internet, or may be provided by recording it on a non-transitory recording medium such as a memory card.

[0038] The control unit 104 performs control related to the mounting of the components 30. The control unit 104 controls each unit of the mounting apparatus 10. The control unit 104 is electrically connected to, for example, the mounting head 102, the detection unit 103, the movement unit 105, the conveyance unit 106, the multiple feeders 107, and the fixed camera 108. The control unit 104 outputs a control signal to the movement unit 105 and controls the movement unit 105 so as to mount the components 30 captured by the capture unit 122 on the mounting surface 401 of the board 40. The control unit 104 also outputs a control signal to the detection unit 103 and the fixed camera 108 to control the detection unit 103 and the fixed camera 108, and acquires images captured by the detection unit 103 and the fixed camera 108 from the detection unit 103 and the fixed camera 108.

[0039] The control unit 104 outputs a control signal to the transport unit 106, and controls the transport unit 106 so that the board 40 is positioned in the mounting space.

[0040] The control unit 104 also outputs control signals to the plurality of feeders 107 to control the plurality of feeders 107 so that the components 30 are positioned at the respective component supply ports 171 .

[0041] The control unit 104 transmits a plurality of pieces of splicing information corresponding to the plurality of feeders 107 to the management system 20 via the communication unit 101. The splicing information includes worker information for identifying the worker performing the splicing work, feeder identification information for identifying the feeder 107 on which the splicing work is performed, and component information for identifying the components 30 included in the storage tape 14 that is the target of the splicing work.

[0042] When the detection unit 103 detects the connected portion of the storage tape 14, the control unit 104 determines that the capture unit 122 has started capturing at the connected portion. For example, after the detection unit 103 detects the connected portion of the storage tape 14, the control unit 104 determines whether a predetermined number (e.g., 100) of components 30 have been fed into the component supply port 171. When the control unit 104 determines that the predetermined number of components 30 have been fed into the component supply port 171, it determines that the capture unit 122 has started capturing at the connected portion.

[0043] The control unit 104 acquires a capture result indicating whether capture of the component 30 was successful or unsuccessful for each component 30 present in a management target section that is a predetermined section from the connecting portion for each of the multiple feeders 107. The control unit 104 transmits capture information for each feeder 107 to the management system 20 via the communication unit 101. The capture information includes capture result information indicating the capture result of the component 30, feeder identification information of the corresponding feeder 107, and a section flag indicating whether capture occurred within the management target section that is the predetermined section from the connecting portion.

[0044] When the control unit 104 receives from the outside capture-related information about a feeder corresponding to an operator whose capture error value is equal to or greater than a predetermined value, the control unit 104 performs a stabilization process, which is a process for improving the stability of the capture operation in which the mounting head 102 captures components, based on the capture-related information. The capture-related information is information about the feeder 107 corresponding to the operator whose capture error value is equal to or greater than a predetermined value. The capture error value is a value related to a capture error that occurred in a management target section, which is a predetermined section from the connection portion where the storage tape 14 is connected by the splicing work performed by the operator.

[0045] The control unit 104 receives, via the communication unit 101 from the management system 20, the capture-related information regarding the feeder corresponding to the worker whose capture error value is equal to or greater than a predetermined value.

[0046] Here, the capture-related information includes feeder identification information that identifies the feeders 107 whose capture error value is equal to or greater than a predetermined value. For example, based on the received capture-related information, the control unit 104 creates a list including one or more feeder identification information corresponding to one or more feeders 107 whose capture error value is equal to or greater than a predetermined value.

[0047] The control unit 104 performs a stabilization process, which is a process for improving the stability of the capture operation in which the mounting head 102 captures the component 30, based on the capture-related information transmitted from the management system 20. The control unit 104 identifies a feeder 107 to be subjected to the stabilization process from among the multiple feeders 107 used in one or more turn operations, based on the capture-related information. The control unit 104 identifies a feeder 107 to be subjected to the stabilization process based on feeder identification information included in the capture-related information. In this embodiment, the control unit 104 identifies a feeder 107 to be subjected to the stabilization process based on the created list.

[0048] In this embodiment, as a stabilization process, the control unit 104 changes the parameters of the capture operation for the feeder 107 to be processed so as to slow down the capture operation. Here, the parameters are at least one of the speed of the feed operation by which the feeder 107 feeds the storage tape 14 and the speed of the lifting operation by which the capture unit 122 moves up and down when the capture unit 122 captures components 30 from the feeder 107. For example, the control unit 104 changes the parameters of the capture operation for the feeder 107 to be processed so as to slow down the speed of the feed operation. Furthermore, the control unit 104 changes the parameters of the capture operation for the feeder 107 to be processed so as to slow down the speed of the lifting operation.

[0049] Here, the stabilization process is performed in a predetermined section from the connecting portion of the storage tape 14. Therefore, the control unit 104 changes the parameters of the capture operation during the capture operation within the predetermined section. If the parameters of the capture operation are changed, the control unit 104 updates the parameters of the capture operation to the values ​​before the change when capture of the component 30 within the predetermined section from the connecting portion is completed. In other words, in sections other than the predetermined section from the connecting portion, the capture operation is performed at the normal feed speed and lifting speed.

[0050] The control unit 104 does not change the parameters of the capture operation for feeders 107 that are not the target of the stabilization process, i.e., feeders 107 that correspond to feeder identification information that is not included in the created list. In other words, the control unit 104 controls the feeders 107 that are not the target of the stabilization process to perform the capture operation at the normal feed speed and lifting speed.

[0051] Furthermore, as a stabilization process, the control unit 104 causes the imaging unit 109 to capture an image of the capture position (component supply port 171). For example, after changing the parameters of the capture operation, if a capture error occurs with respect to the feeder 107 being processed, the control unit 104 causes the imaging unit 109 to capture an image of the capture position. Based on the image captured by the imaging unit 109, the control unit 104 determines whether the location (storage location) where the component 30 should be stored is empty (i.e., the component 30 is not stored). If it is determined that the location is empty, the control unit 104 performs a feeding operation of the feeder 107 being processed without raising or lowering the capture unit 122 until it is determined that the component 30 is stored in the storage location. In other words, the control unit 104 performs a cueing operation for the component 30 until it is determined that the component 30 is stored in the storage location. Furthermore, the control unit 104 corrects the position of the capture unit 122 by controlling the moving unit 105 based on the position of the part 30 imaged by the imaging unit 109 so that the position of the capture unit 122 is positioned at the center of the part 30.

[0052] (2.2.6) Moving Unit The moving unit 105 positions (aligns) the capturing unit 122 of the mounting head 102 at the capturing position of the component 30 (component supply port 171) and at the mounting position of the component 30 on the board 40. That is, the moving unit 105 is a device for moving the mounting head 102, including the capturing unit 122. The moving unit 105 moves the head unit 121 horizontally within the X-Y plane, and moves the capturing unit 122 vertically along the Z axis. That is, the moving unit 105 moves the head unit 121 in the X-axis direction and the Y-axis direction. In this embodiment, the capturing unit 122 is fixed to the head unit 121, and therefore the moving unit 105 also moves the capturing unit 122 together with the head unit 121 in the X-axis direction and the Y-axis direction. In FIG. 2, the mounting head 102 is moved by the moving unit 105 between above the component supply port 171 of the feeder 107 and above the board 40 positioned in the mounting space of the transport unit 106 .

[0053] Specifically, as shown in FIG. 1, the moving unit 105 has a horizontal driving unit 151 and a vertical driving unit 152 .

[0054] The horizontal drive unit 151 includes an X-axis drive unit 153 and a Y-axis drive unit 154. The X-axis drive unit 153 moves the mounting head 102 linearly in the X-axis direction. The Y-axis drive unit 154 moves the mounting head 102 linearly in the Y-axis direction. The Y-axis drive unit 154 moves the mounting head 102 linearly in the Y-axis direction by moving the mounting head 102 together with the X-axis drive unit 153 along the Y-axis. The X-axis drive unit 153 includes an X-axis motor (not shown) and drives the X-axis motor. The Y-axis drive unit 154 includes a Y-axis motor (not shown) and drives the Y-axis motor. Each of the X-axis motor and the Y-axis motor is, for example, a linear motor. Therefore, in this embodiment, the X-axis drive unit 153 moves the mounting head 102 linearly in the X-axis direction by using a driving force generated by the X-axis motor when power is supplied. Furthermore, the Y-axis driving unit 154 receives power supply and uses the driving force generated by the Y-axis motor to move the mounting head 102 linearly in the Y-axis direction.

[0055] The vertical drive unit 152 moves the capturing unit 122 linearly in the Z-axis direction. Furthermore, the vertical drive unit 152 rotates the capturing unit 122 in a rotational direction (hereinafter referred to as the "θ direction") around an axis along the Z-axis direction. That is, the vertical drive unit 152 is an actuator that moves the capturing unit 122 linearly in the Z-axis direction and rotates the capturing unit 122 in the θ direction. In the present embodiment, as an example, the vertical drive unit 152 drives the capturing unit 122 in the Z-axis direction by a driving force generated by a linear motor. Furthermore, the vertical drive unit 152 drives the capturing unit 122 in the θ direction by a driving force generated by a rotary motor. As described above, the head unit 121 of the mounting head 102 moves linearly in the X-axis direction and the Y-axis direction by the horizontal drive unit 151. As a result, the capture unit 122 attached to the head unit 121 can be moved in the X-axis direction, Y-axis direction, Z-axis direction, and θ direction by the horizontal drive unit 151 and the vertical drive unit 152 .

[0056] (2.2.7) Transport Unit The transport unit 106 is a device for transporting the board 40. For example, as shown in FIG. 2 , the transport unit 106 has a pair of conveyor mechanisms 161. The transport unit 106 transports the board 40 in the X-axis direction (a direction perpendicular to the plane of FIG. 2 ) using the pair of conveyor mechanisms 161. The transport unit 106 transports the board 40 to a mounting space that is at least below the mounting head 102, that is, that faces the capture unit 122 in the Z-axis direction. The transport unit 106 then stops the board 40 in the mounting space until the mounting head 102 has completed mounting the components 30 on the board 40.

[0057] (2.2.8) Feeder Each of the multiple feeders 107 supplies components 30 stored on the storage tape 14 to a capture position (component supply port 171) where the components are captured by the mounting head 102. As an example, each feeder 107 has a tape feeder that supplies the components 30 stored on the storage tape 14. Each feeder 107 moves the components 30 to the component supply port 171 by feeding out the storage tape 14 in the Y-axis direction using the tape feeder.

[0058] (2.2.9) Fixed Camera The fixed camera 108 captures an image from below of the mounting head 102 moving between above the component supply port 171 of the feeder 107 and above the board 40 positioned in the mounting space. Therefore, the image captured by the fixed camera 108 shows the component 30 captured by the capture unit 122. In other words, the image captured by the fixed camera 108 contains information about the relative positional relationship between the capture unit 122 and the component 30, in other words, information about the deviation of the component 30 from the capture unit 122.

[0059] It is preferable that the fixed camera 108 captures an image of the mounting head 102 from below as it moves from the component supply port 171 toward the board 40. In this case, the fixed camera 108 does not capture images all the time, but captures an image when the capturing unit 122 capturing the component 30 passes above the fixed camera 108. The fixed camera 108 may also be installed below the component supply port 171.

[0060] (2.3) Management System The management system 20 manages the workers who performed splicing work to connect the ends of the storage tape 14 attached to the feeder 107. The management system 20 calculates a capture error value for the worker, which is a value related to a capture error that occurred in a predetermined section (a management target section) from the connection portion where the storage tape 14 is connected. The management system 20 transmits to the mounting device 107 capture-related information related to the feeder 107 corresponding to the worker whose capture error value is equal to or greater than a predetermined value.

[0061] As shown in FIG. 1, the management system 20 includes a collation management system 21 and an analysis system 22 .

[0062] The verification management system 21 manages the workers who performed the splicing work of joining the ends of the storage tape 14 attached to the feeder 107. As shown in FIG. 1 , the verification management system 21 has a first communication unit 211, a second communication unit 212, a first memory unit 213, and a first processing unit 214.

[0063] The first communication unit 211 has a communication interface for communicating with the mounting device 10. The communication between the first communication unit 211 and the mounting device 10 may be wired communication or wireless communication.

[0064] The second communication unit 212 has a communication interface for communicating with the analysis system 22. The communication between the second communication unit 212 and the analysis system 22 may be wired communication or wireless communication.

[0065] The first storage unit 213 is configured with a device selected from a read-only memory (ROM), a random access memory (RAM), an electrically erasable programmable read-only memory (EEPROM), etc. The first storage unit 213 stores the worker who performed the splicing work. Specifically, the first storage unit 213 stores worker information that identifies the worker who performed the splicing work for each of the multiple feeders.

[0066] The first processing unit 214 can be realized, for example, by a computer system having one or more processors and one or more memories. That is, the first processing unit 214 functions as a computer system in which one or more processors execute a program recorded in one or more memories of the computer system. Here, the program is pre-recorded in the memory of the computer system, but it may also be provided via a telecommunications line such as the Internet, or may be provided by being recorded on a non-transitory recording medium such as a memory card.

[0067] The first processing unit 214 receives the splicing information from the mounting device 10 via the first communication unit 211. The first processing unit 214 stores the received splicing information in the first storage unit 213.

[0068] The first processing unit 214 compares the splicing information with a work schedule list, which is a list stored in advance in the first storage unit 213 and includes a work schedule, to confirm that the work is being performed correctly. The work schedule list includes worker information, feeder identification information for the feeder 107 on which the worker represented by the worker information will work, component information for the components 30 sent by the feeder 107, and the time period in which the worker will work on the feeder 107. The first processing unit 214 confirms that the time at which the splicing information was received is within the time period included in the work schedule list. Furthermore, the first processing unit 214 confirms that the worker information, feeder identification information, and component information included in the splicing information are identical to the various information corresponding to the time period.

[0069] The first processing unit 214 receives request information from the analysis system 22, including feeder identification information and requesting worker information corresponding to the feeder identification information, via the second communication unit 212. The first processing unit 214 acquires splicing information including the feeder identification information included in the received request information from the first storage unit 213. The first processing unit 214 acquires worker information included in the acquired splicing information. The first processing unit 214 outputs the acquired worker information to the analysis system 22 via the second communication unit 212.

[0070] The analysis system 22 calculates a capture error value for an operator, which is a value related to a capture error that occurred in a predetermined section (a management target section) from a connection portion where the storage tape 14 is connected. The analysis system 22 transmits capture-related information related to a feeder 107 corresponding to an operator whose capture error value is equal to or greater than a predetermined value to the mounting device. As shown in FIG. 1 , the analysis system 22 has a third communication unit 221, a fourth communication unit 222, a second memory unit 223, and a second processing unit 224.

[0071] The third communication unit 221 has a communication interface for communicating with the mounting device 10. The communication between the third communication unit 221 and the mounting device 10 may be wired communication or wireless communication.

[0072] The fourth communication unit 222 has a communication interface for communicating with the verification management system 21. The communication between the fourth communication unit 222 and the verification management system 21 may be wired communication or wireless communication.

[0073] The second storage unit 223 is configured with a device selected from a ROM, a RAM, an EEPROM, etc. The second storage unit 223 stores the acquisition information in association with the worker information. Specifically, the second storage unit 223 stores the acquisition information for each of the multiple feeders.

[0074] The second processing unit 224 can be realized, for example, by a computer system having one or more processors and one or more memories. That is, the second processing unit 224 functions as a computer system in which one or more processors execute a program recorded in one or more memories of the computer system. Here, the program is pre-recorded in the memory of the computer system, but it may also be provided via a telecommunications line such as the Internet, or may be provided by being recorded on a non-transitory recording medium such as a memory card.

[0075] The second processing unit 224 receives the captured information for each feeder 107 and each component 30 from the mounting apparatus 10 via the third communication unit 221 .

[0076] The second processing unit 224 outputs request information including the feeder identification information for each feeder 107 to the verification management system 21 via the fourth communication unit 222. The second processing unit 224 receives worker information corresponding to the output request information from the verification management system 21 via the fourth communication unit 222. The second processing unit 224 associates the received worker information with the supplementary information and feeder identification information corresponding to the feeder identification information included in the output request information, and stores them in the second storage unit 223.

[0077] The second processing unit 224 calculates a capture miss value based on the capture information. For example, the second processing unit 224 counts the number of capture misses for each feeder 107 based on multiple pieces of capture result information included in the capture information whose section flag indicates capture within the management target section. At this time, a group made up of multiple pieces of capture information whose section flag indicates capture within the management target section is formed each time a new storage tape 14 is switched to. The second processing unit 224 counts the number of capture misses for each group. In other words, the second processing unit 224 counts the number of capture misses for each storage tape 14.

[0078] The second processing unit 224 calculates, for each feeder 107, the ratio of components 30 that have failed to be captured (missedly picked up) to the total number of components 30 present in the management section as a capture failure value. More specifically, the second processing unit 224 calculates, for each feeder 107, the ratio (proportion) of the number of components 30 that have failed to be captured (missedly picked up) to the total number of components 30 present in the management section (100 in this example). The second processing unit 224 calculates, as the capture failure value, the average value of the ratio calculated a predetermined number of times (e.g., the most recent five times) for the same feeder 107. If the ratio has been calculated fewer than five times, the second processing unit 224 calculates the average value of the ratio for the calculated number of times. In other words, the capture failure value can be said to be the ratio of components 30 that have failed to be captured (missedly picked up) to the total number of components 30 present in the management section.

[0079] The capture failure value may be the maximum value of the most recent five calculated ratios, rather than the average value of the ratios. If the number of calculations is less than five, the second processing unit 224 sets the maximum value of one or more calculated ratios as the capture failure value.

[0080] Alternatively, the second processing unit 224 may calculate the ratio of the total number of components 30 that have experienced capture errors (pickup errors) to the total number of components 30 that exist in the section to be managed over a predetermined number of times (e.g., the most recent five times). That is, the second processing unit 224 may calculate the ratio of the total number of components 30 that have experienced capture errors (pickup errors) over a predetermined number of times to the total number obtained by multiplying the total number of components 30 that exist in the section to be managed by the predetermined number of times. If the number of calculations is less than five, the second processing unit 224 calculates the ratio of the total number of components 30 that have experienced capture errors (pickup errors) to the total number of components 30 over the calculated number of times.

[0081] Furthermore, when a different worker performs splicing on the same feeder 107, the second processing unit 224 resets the number of times the ratio has been calculated to 0 at the time of the change. For example, when the worker represented by the worker information included in the splicing information previously received for the same feeder 107 is different from the worker represented by the worker information included in the splicing information currently received, the second processing unit 224 resets the number of times the ratio has been calculated to 0. In other words, the second processing unit 224 calculates the capture error value for each worker on the same feeder 107.

[0082] The second processing unit 224 transmits, to the mounting device 10, capture-related information about the feeder 107 corresponding to the worker whose capture error value is equal to or greater than the predetermined value, via the third communication unit 221. Specifically, the second processing unit 224 transmits, to the mounting device 10, capture-related information including the feeder identification information of the feeder 107 associated with the worker information of the worker whose capture error value is equal to or greater than the predetermined value.

[0083] (3) Operation Here, the operation of the mounting system 1 will be described.

[0084] (3.1) Operation of the Implementation System Related to Calculation and Transmission of Capture Miss Values ​​First, the operation of the implementation system 1 related to calculation and transmission of capture miss values ​​will be described with reference to FIG.

[0085] The analysis system 22 of the management system 20 performs an acquisition process (step S1). The analysis system 22 acquires acquisition information and worker information. Specifically, the second processing unit 224 of the analysis system 22 receives the acquisition information from the mounting device 10 for each feeder 107 and each component 30. Furthermore, the second processing unit 224 receives from the verification management system 21 the worker information corresponding to the request information output by the second processing unit to the verification management system 21.

[0086] The second processing unit 224 performs a calculation process (step S2). The second processing unit 224 calculates a capture failure value based on the capture information. For each feeder 107, the second processing unit 224 counts the number of capture failures based on multiple pieces of capture result information included in the capture information whose section flag indicates capture within the management section. For each feeder 107, the second processing unit 224 calculates the capture failure value as the ratio of components 30 that have experienced capture failures (pickup failures) to components 30 present in the management section.

[0087] The second processing unit 224 determines whether the capture failure value in the feeder 107 to be determined is equal to or greater than a predetermined value (step S3).

[0088] If it is determined that the capture error value is equal to or greater than the predetermined value ("Yes" in step S3), the second processing unit 224 performs a transmission process (step S4). The second processing unit 224 transmits the capture-related information to the mounting device 10.

[0089] If the second processing unit 224 determines that the capture error value is not greater than or equal to the predetermined value ("No" in step S3), or after the second processing unit 224 performs the transmission process, the second processing unit 224 determines whether the determination process in step S3 has been performed for all feeders 107 (step S5).

[0090] If the second processing unit 224 determines that the determination process has not been performed on all feeders 107 ("No" in step S5), the process returns to step S3. The second processing unit 224 performs the above-described determination process on the feeders 107 for which the determination process has not been performed.

[0091] If the determination process has been performed for all feeders 107 ("Yes" in step S5), the mounting device 10 performs a list creation process (step S6). Based on the received capture-related information, the control unit 104 of the mounting device 10 creates a list including one or more feeder identification information corresponding to one or more feeders 107 whose capture error value is equal to or greater than a predetermined value.

[0092] (3.2) Operation of Mounting Apparatus Related to Mounting Operation Here, the operation of the mounting apparatus 10 when capturing the component 30 and mounting the captured component 30 on the board 40 will be described with reference to FIG.

[0093] The control unit 104 of the mounting device 10 determines whether the feeder 107 that sends the component 30 to the capture position (component supply port 171) is a target for stabilization processing (step S11). Based on the list created in step S6, the control unit 104 identifies (determines) whether the feeder 107 that sends the component 30 to the capture position is a feeder 107 that is a target for stabilization processing.

[0094] If it is determined that the feeder 107 that sends the component 30 to the capture position is not the feeder 107 that is the target of the stabilization process ("No" in step S11), the control unit 104 performs a first control process (step S12). The control unit 104 controls the feeder 107 and the mounting head 102 to set the feed speed of the feeder 107 to the normal feed speed and the lift speed of the capture unit 122 to the normal speed, and to deliver and capture the component 30. At this time, the capture operation is performed at the normal feed speed and normal lift speed, and capture information including the capture result of the component 30 is sent to the management system 20.

[0095] When it is determined that the feeder 107 that sends the component 30 to the capture position is the feeder 107 that is the target of the stabilization process ("Yes" in step S11), the control unit 104 performs a second control process (step S13). The control unit 104 changes the parameters of the capture operation for the feeder 107 to be processed. For example, the control unit 104 changes the parameters of the capture operation for the feeder 107 to be processed so that at least one of the feeding speed and the lifting speed is slowed. This allows the control unit 104 to control at least one of the feeder 107 and the mounting head 102 so that at least one of the feeding speed and the lifting speed is slowed. At this time, the capture operation is performed with at least one of the feeding speed and the lifting speed slower than normal, and capture information including the capture result of the component 30 is transmitted to the management system 20.

[0096] After capturing the components 30, the control unit 104 determines whether all of the components 30 that should be captured in one turn have been captured (step S14). For example, since the mounting head 102 of this embodiment has one capturing unit 122, the number of components 30 that should be captured in one turn is one. For example, when one component 30 is captured by the mounting head 102, the control unit 104 determines that all of the components 30 that should be captured in one turn have been captured.

[0097] If it is determined that all of the components 30 to be acquired in one turn have been captured ("Yes" in step S14), the control unit 104 performs mounting processing (step S15). The control unit 104 controls, for example, the mounting head 102 so that all of the captured components 30 for one turn are mounted on the board 40.

[0098] If the control unit 104 determines that all of the parts 30 to be acquired in one turn have not been captured ("No" in step S14), the process returns to step S11.

[0099] (4) Advantages As described above, the mounting system 1 of this embodiment includes a mounting apparatus 10 and a management system 20. The mounting apparatus 10 includes a mounting head 102, a feeder 107, and a control unit 104. The mounting head 102 has a capture unit 122 that captures components 30 from a storage tape 14 that stores the components 30. The mounting head 102 mounts the components 30 captured by the capture unit 122 on a board 40. The feeder 107 supplies the components 30 stored on the storage tape 14 to a capture position (component supply port 171) where the components 30 are captured by the mounting head 102. The control unit 104 controls the mounting of the components 30. The management system 20 manages the worker who performed the splicing work to connect the ends of the storage tape 14 attached to the feeder 107. The management system 20 calculates a capture error value for the worker, which is a value related to capture errors that occurred in a predetermined section from the connection portion where the storage tape 14 is connected. The management system 20 transmits capture-related information relating to the feeder corresponding to the worker whose capture error value is equal to or greater than a predetermined value to the mounting device 10. The control unit 104 performs a stabilization process, which is a process for improving the stability of the capture operation in which the mounting head 102 captures the component 30, based on the capture-related information transmitted from the management system 20.

[0100] According to this configuration, when the capture error value is equal to or greater than a predetermined value, stabilization processing is performed on the corresponding feeder 107. This improves productivity compared to when stabilization processing is always performed. This reduces the occurrence of component suction errors at the connecting portions of the storage tape 14, while also improving productivity.

[0101] The mounting apparatus 10 of this embodiment includes a mounting head 102, a feeder 107, and a control unit 104. The mounting head 102 has a capture unit 122 that captures components 30 from a storage tape 14 that stores the components 30. The mounting head 102 mounts the components 30 captured by the capture unit 122 on a board 40. The feeder 107 supplies the components 30 stored on the storage tape 14 to a capture position (component supply port 171) where the components 30 will be captured by the mounting head 102. The control unit 104 controls the mounting of the components 30. A worker splices the storage tape 14 attached to the feeder 107 to connect the ends of the storage tape 14. When the control unit 104 receives capture-related information from an external device, it performs a stabilization process, which is a process for stabilizing the capture operation in which the mounting head 102 captures the components 30, based on the capture-related information. The capture-related information is a value related to a capture error that occurred in a specified section from the connection part where the storage tape 14 is connected, and is information about the feeder 107 corresponding to the worker whose capture error value for the worker is equal to or greater than a specified value.

[0102] This configuration reduces the occurrence of errors in picking up components 30 at the connecting portions of the storage tape 14, while improving productivity.

[0103] Furthermore, the management system 20 of this embodiment manages workers who performed splicing work to join the ends of storage tapes 14 that store components 30 to storage tapes attached to feeders 107. The management system 20 calculates a capture error value for each worker, which is a value related to capture errors that occurred in a predetermined section from the connection portion where the storage tapes 14 are connected. The management system 20 transmits capture-related information related to the feeders 107 corresponding to workers whose capture error values ​​are equal to or greater than a predetermined value to the mounting device 10, and causes the mounting device 10 to perform a stabilization process that stabilizes the capture operation that captures components 30. The mounting device 10 is a device that captures components 30 and mounts them on a board 40.

[0104] According to this embodiment, the capture-related information is transmitted to the mounting device 10, and the mounting device 10 is caused to perform stabilization processing, thereby improving productivity while reducing the occurrence of errors in suction of the components 30 at the connecting portion of the storage tape 14.

[0105] (5) Modifications Modifications are listed below. The modifications described below can be applied in appropriate combination with the above-described embodiment.

[0106] (5.1) Modification 1 In the above embodiment, the control unit 104 is configured to capture an image of the capture position (component supply port 171) using the imaging unit 109 when a capture error occurs for the feeder 107 undergoing stabilization processing. However, the present invention is not limited to this configuration.

[0107] The control unit 104 may image the capture position using the imaging unit 109, regardless of whether a capture error has occurred for the feeder 107 for which the stabilization process is being performed. That is, the control unit 104 may image the capture position using the imaging unit 109 as the stabilization process for the feeder 107 for which the capture error value is equal to or greater than a predetermined value.

[0108] (5.2) Modification 2 In the above embodiment, the mounting head 102 is configured to have one capturing portion 122. However, the present invention is not limited to this configuration.

[0109] The mounting head 102 may have multiple capture units 122. In this case, the multiple capture units 122 correspond to multiple feeders 107, respectively. When the control unit 104 targets a feeder 107 corresponding to one of the multiple capture units 122 that capture multiple components 30 that are targets of simultaneous capture as the target of stabilization processing, the control unit 104 further changes the parameters of the capture operation for another feeder 107 corresponding to the remaining capture unit 122 of the multiple capture units 122. For example, when a component 30 has been captured by each of the multiple capture units 122 included in the mounting head 102, the control unit 104 determines that all of the components 30 that should be obtained in one turn have been captured.

[0110] (5.3) Modification 3 The second processing unit 224 may calculate the capture error value as the average value of the number of capture errors in the most recent five splicing operations calculated for the same feeder 107. That is, the capture error value may be the number of capture errors (sucking errors) for components 30 present in the management target section. Also in modification 3, when a different worker performs splicing on the same feeder 107, the second processing unit 224 resets the number of splicing operations for which the number of capture errors was calculated to 0 at the time of the change. That is, even in this case, the second processing unit 224 calculates the capture error value for each worker on the same feeder 107.

[0111] Alternatively, the capture failure value may be the maximum value of the most recent five calculated ratios, rather than the average value of the ratios described in the embodiment. If the number of calculations is less than five, the second processing unit 224 sets the maximum value of one or more calculated ratios as the capture failure value.

[0112] Alternatively, the second processing unit 224 may calculate the ratio of the total number of components 30 that have experienced capture errors (pickup errors) to the total number of components 30 that exist in the section to be managed over a predetermined number of times (e.g., the most recent five times). That is, the second processing unit 224 may calculate the ratio of the total number of components 30 that have experienced capture errors (pickup errors) over a predetermined number of times to the total number obtained by multiplying the total number of components 30 that exist in the section to be managed by the predetermined number of times.
