Description

[Technical field]

[0001] The technology disclosed in this specification relates to a component mounter. [Background technology]

[0002] Patent Document 1 discloses a component mounter that creates component data for components to be mounted on a board. This component mounter creates the component data based on CAD data that describes the shapes and dimensions of the components to be used in production, and image data of the components that are actually captured by a camera while the component mounter is operating (during production).

[0003] [Patent Document 1] JP 2011-211088 A Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, while a component mounter is in operation, a camera captures an image of a component that is actually mounted on a board, and component data for that component is created. Therefore, when creating component data for other components (i.e., components that are not used in production while the component mounter is in operation) in the component mounter, it is necessary to stop the operation of the component mounter. This specification provides a technology that can capture images of various types of components required for creating component data, etc., without reducing production efficiency. [Means for solving the problem]

[0005] A component mounter disclosed in this specification mounts components on a board by executing a production plan including at least one job. The component mounter includes a storage unit, a mounting unit, an imaging unit, and a control unit. The storage unit stores a production plan including at least a job for mounting a first component on the board, but not including a job for mounting a second component different from the first component on the board. The mounting unit mounts the first component on a board to be produced. The imaging unit images the component. The control unit controls the imaging unit to cause the imaging unit to image the second component during a predetermined period during which the production plan is being executed and the mounting unit is not mounting the first component on the board.

[0006] When a board is produced by a component mounter, a production plan including jobs (instructions including the type and number of boards to be produced, etc.) is generally created in advance, and predetermined components are mounted on the board according to the production plan. Here, when actually producing a board according to the production plan, a predetermined period during which the mounting unit in the component mounter does not operate (i.e., a time during which the mounting unit is not mounting components (so-called idle time)) may occur due to, for example, waiting for a process of another work machine. In the above-mentioned component mounter, during this predetermined period, an image of a second component (more specifically, a component not used in production) different from the first component mounted on the board based on the production plan is captured. Therefore, an image of the second component not used in the production can be captured without stopping the production by the component mounter. [Brief description of the drawings]

[Diagram 2] FIG. 1 is a diagram showing a schematic configuration of a component mounter according to an embodiment. [Diagram 3] 3 is a cross-sectional view taken along line III-III in FIG. 2 . [Figure 4] 11 is a flowchart showing a process executed by a management device according to the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The main features of the embodiment described below are listed below. Note that the technical elements described below are independent technical elements that exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.

[0009] In an embodiment of the present technology, the mounter may further include a transport unit that transports the board to be produced to a component mounting position. The predetermined period may be a period during which the production plan is being executed and the board is not transported to the component mounting position by the transport unit.

[0010] When mounting components according to a production plan, there may be periods during which the board is not carried into the component mounter due to, for example, waiting for another work machine to complete a process, etc. In the above configuration, by capturing an image of the second component during such periods, it is possible to suppress a decrease in production efficiency.

[0011] In an embodiment of the present technology, the component mounter may further include a feeder holding unit to which a plurality of component feeders for supplying the components are attached, and a nozzle for suctioning the components supplied from the component feeders. A first component feeder containing the first components and a second component feeder containing the second components may be attached to the feeder holding unit. The control unit may cause the nozzle to suction the second components supplied from the second component feeder during the predetermined period, and cause the imaging unit to capture an image of the second components.

[0012] In the above configuration, the second component feeder containing the second component is attached to the feeder holding section, so that the second component can be imaged by utilizing the nozzle for mounting the components (i.e., by adsorbing the second component to the nozzle).

[0013] In an embodiment of the present technology, the component mounter may further include an automatic placement mechanism capable of attaching and detaching the component feeder to the feeder holding unit. The control unit may control the automatic placement mechanism to attach the second component feeder to the feeder holding unit when it is determined based on the production plan that the predetermined period will occur.

[0014] In the above configuration, when it is determined that the predetermined period will occur, the second component feeder is automatically attached to the feeder holding unit, which eliminates the need for an operator to manually attach the second component feeder, improving convenience.

[0015] In one embodiment of the present technology, the control unit may control the automatic placement mechanism to remove the second component feeder from the feeder holding unit when the imaging unit has finished imaging the second component.

[0016] In the above configuration, when the imaging of the second component is completed, the second component feeder is automatically removed from the feeder holder. Therefore, for example, when it is desired to image another component (i.e., a third component), a component feeder containing the other component can be attached in the position where the second component feeder was attached.

[0017] In one embodiment of the present technology, the component mounter may be installed in a production line including a plurality of other component mounters. The component mounter and each of the plurality of other component mounters may be capable of communicating with each other. When the control unit receives predetermined information related to the progress of the production plan from the other component mounters, the control unit may cause the imaging unit to capture an image of the second component.

[0018] When components are mounted on a production line according to a production plan, an event may occur in one of the mounters that hinders the progress of the production plan. For example, if an error or the like occurs in another mounter, the transportation of the board may be delayed, and a period of time during which processing on the board cannot be performed may occur. In the above configuration, in such a case, the second component is imaged in response to receiving predetermined information regarding the production plan from the other mounter. Therefore, if an error or the like occurs at an unintended timing in the production line, the second component can be imaged by utilizing the period during which the mounter cannot operate.

[0019] In an embodiment of the present technology, the control unit may create part data of the second part based on an image captured by the imaging unit.

[0020] In the above configuration, by creating component data for the second component based on the captured image, the component data can be used when mounting the second component.

[0021] (Example) Hereinafter, the component mounter 10 of the embodiment will be described with reference to the drawings. As shown in FIG. 1, the component mounter 10 is communicably connected to a management device 8. The management device 8 manages a plurality of component mounters 10. A production line 100 is configured by the management device 8 and a plurality of component mounters 10. The management device 8 is configured using a computer having a CPU and a memory. The management device 8 controls the operation of each component mounter 10 to control the entire production line 100. That is, the management device 8 determines the type and position of the electronic component 4 to be mounted on the board 2 by each of the plurality of component mounters 10, and instructs the component mounter 10. Each component mounter 10 operates based on the instruction of the management device 8, so that the necessary electronic component 4 is mounted on the board 2. Note that the configuration of the production line 100 shown in FIG. 1 is an example, and other board working machines such as a printer and an inspection machine may be installed in addition depending on the type of the board 2 to be produced.

[0022] The component mounter 10 mounts electronic components 4 on the board 2. The component mounter 10 is also called a surface mounter or chip mounter. The board 2 is sent from one end of the production line 100 to the other end. Predetermined electronic components 4 are mounted on the board 2 by each component mounter 10. The board 2 sent to the other end of the production line 100 is shipped as a final product, or sent to a subsequent process as a semi-finished product.

[0023] As shown in FIGS. 2 and 3, the component mounter 10 includes a mounting unit 5, a plurality of component feeders 12, a feeder holding unit 14, a bottom imaging camera 22, an operation panel 28, a loader 30, and a control device 40.

[0024] Each component feeder 12 accommodates a plurality of electronic components 4. The component feeders 12 are detachably attached to the feeder holder 14 and supply the electronic components 4 to the head 16. The specific configuration of the component feeders 12 is not particularly limited. Each component feeder 12 may be, for example, a tape feeder that accommodates a plurality of electronic components 4 in the form of a rolled tape, a tray feeder that accommodates a plurality of electronic components 4 on a tray, or a bulk feeder that accommodates a plurality of electronic components 4 randomly in a container.

[0025] Feeder holding unit 14 has a plurality of slots, and component feeders 12 can be removably installed in each of the plurality of slots. Feeder holding unit 14 may be fixed to component mounter 10, or may be detachable from component mounter 10.

[0026] The loader 30 is a device that automatically attaches and detaches the component feeder 12 to and from the feeder holding unit 14. The loader 30 is configured to remove and collect the component feeder 12 to be replaced from the feeder holding unit 14, and to attach the component feeder 12 to be used in production to the feeder holding unit 14. The component mounters 10 that make up the production line 100 are arranged in one direction, and the loader 30 is configured to be movable in parallel to each slot of the feeder holding unit 14 of each component mounter 10 by a guide rail (not shown) provided along the one direction (X direction in FIG. 3). The loader 30 includes a control device (not shown), and the control device is configured to be able to communicate with the control device 40 of each component mounter 10.

[0027] The mounting section 5 mounts the electronic components 4 on the board 2. The mounting section 5 includes a head 16, a side imaging camera 20, a moving device 18 that moves the head 16 and the side imaging camera 20, and a board conveyor 26.

[0028] The moving device 18 moves the head 16 and the side imaging camera 20 between the component feeder 12 and the board 2. The moving device 18 in this embodiment is an XY robot that moves a moving base 18a in the X and Y directions. The moving device 18 is composed of a guide rail that guides the moving base 18a, a moving mechanism that moves the moving base 18a along the guide rail, a motor that drives the moving mechanism, and the like. The moving device 18 is disposed above the component feeder 12 and the board 2. The head 16 and the side imaging camera 20 are attached to the moving base 18a. The head 16 and the side imaging camera 20 are moved above the component feeder 12 and above the board 2 by the moving device 18.

[0029] The head 16 includes one or more nozzles 6 for suctioning the electronic components 4. The nozzles 6 are detachable from the head 16. The nozzles 6 are held by the head 16 so as to be movable in the vertical direction (Z direction in FIG. 2). The nozzles 6 are configured to be able to move up and down by an actuator (not shown) housed in the head 16 and to suction the electronic components 4. To mount the electronic components 4 on the board 2 using the head 16, first, the moving device 18 moves the head 16 to a component suction position. Next, the nozzle 6 is moved downward until the lower surface (suction surface) of the nozzle 6 abuts against the electronic components 4 housed in the component feeder 12. Next, the moving device 18 moves the head 16 to a component mounting position and positions it relative to the board 2. Next, the nozzle 6 is lowered toward the board 2 to mount the electronic components 4 on the board 2.

[0030] The side imaging camera 20 is attached to the moving base 18a. Therefore, when the head 16 moves, the side imaging camera 20 also moves integrally. The side imaging camera 20 is disposed to the side (Y direction) of the nozzle 6. The side imaging camera 20 captures an image of the electronic component 4 sucked by the nozzle 6 from the side. For example, a CCD camera is used as the side imaging camera 20. Data of the image captured by the side imaging camera 20 is transmitted to the control device 40.

[0031] The bottom surface imaging camera 22 is disposed between the feeder holding unit 14 and the board conveyor 26. The bottom surface imaging camera 22 is installed so that the imaging optical axis faces upward (Z direction), and images the electronic component 4 sucked by the nozzle 6 from below. For example, a CCD camera is used as the bottom surface imaging camera 22. Data of the image captured by the bottom surface imaging camera 22 is transmitted to the control device 40.

[0032] The board conveyor 26 transports the board 2 in the X direction. In this embodiment, the board conveyor 26 is composed of a pair of belt conveyors, a support device attached to the belt conveyors and supporting the board 2 from below, and a drive device that drives the belt conveyor. The board conveyor 26 receives the board 2 from an adjacent board work machine on one side, carries it into the component mounter 10, and positions the board 2 at the component mounting position. When mounting of the electronic components 4 on the board 2 is completed, the board conveyor 26 carries the board 2 out of the component mounter 10 and hands it over to the adjacent board work machine on the other side.

[0033] The operation panel 28 is a display device that provides the worker with various information about the component mounter 10, and is also an input device that receives instructions and information from the worker. The control device 40 is configured using a computer equipped with a CPU and memory. The control device 40 controls the operation of each part of the component mounter 10 based on the production plan transmitted from the management device 8. The control device 40 is also configured to be able to communicate with each of the control devices of the other component mounters 10 that make up the production line 100.

[0034] When mounting the electronic component 4 on the board 2, the side imaging camera 20 and the bottom imaging camera 22 capture an image of the electronic component 4 sucked by the nozzle 6, and the captured image is compared with component data (data describing the type, dimensions, shape, etc. of the electronic component 4) previously stored in the memory of the control device 40 to detect whether the type of the electronic component 4 is appropriate and whether there is any defect, etc., in the electronic component 4. For this reason, for example, when mounting a type of electronic component 4 for which no component data is stored in the control device 40, it is necessary to create new component data.

[0035] As described above, in the production line 100, each mounter 10 executes a process according to the production plan transmitted from the management device 8, thereby producing the board 2 according to the production plan. The production plan transmitted to each mounter 10 includes one or more jobs (commands including the type and number of boards to be produced, the type of electronic components 4 to be mounted, etc.) to be executed by the corresponding mounter 10, and each mounter 10 mounts the electronic components 4 on the board 2 according to the job. Here, when actually producing the board 2 according to the production plan, a predetermined period may occur during which the mounting unit 5 in the mounter 10 does not operate (i.e., the mounting unit 5 does not mount the electronic components 4) due to, for example, waiting for a process of another mounter. In this embodiment, during this predetermined period, an image for creating component data of the electronic components 4 is captured. In particular, in this embodiment, an image of an electronic component 4b (hereinafter referred to as a second component 4b) different from an electronic component 4a (hereinafter referred to as a first component 4a) to be mounted on the board 2 based on the production plan is captured. The second component 4b is a component that is not mounted on the board 2 in the production of the board 2 based on the production plan. In other words, the production plan transmitted to the component mounter 10 includes a job to mount the first component 4a, but does not include a job to mount the second component 4b. Note that the production plan may include a job to mount electronic components 4 other than the first component 4a (but excluding the second component 4b).

[0036] Hereinafter, a process of creating component data for the second components 4b by the component mounter 10 will be described with reference to Fig. 4. When creating component data, first, an operator inputs information on the second components 4b for which component data is to be created (for example, information listed in a specification table provided by a component manufacturer) into the management device 8. The operator also sets the component feeder 12b containing the second components 4b in the loader 30. The operator also inputs information including the type and number of boards 2 to be produced into the management device 8. In response to the input of the information, the process of Fig. 4 is started.

[0037] In S12, the management device 8 creates a production plan based on the input information (information including the type and number of boards 2 to be produced). That is, the management device 8 determines the processing to be executed by each of the mounters 10 constituting the production line 100. Then, in S14, the management device 8 transmits the created production plan to the control device 40 of each mounter 10.

[0038] In S16, the management device 8 determines whether or not the part information of the image capturing target is stored in memory. Here, if the information of the second part 4b has been input in advance by the worker, the management device 8 determines that the part information of the image capturing target is stored, and proceeds to S18. On the other hand, if the management device 8 determines that the part information of the image capturing target is not stored (NO in S16), the management device 8 proceeds to S24.

[0039] In S18, the management device 8 judges whether or not there is a mounter 10 with a non-operating period among the mounters 10 that execute processing according to the production plan. The number and type of electronic components 4 to be mounted on the board 2 may differ for each mounter 10. Therefore, when processing according to the production plan is executed, the processing time for one board 2 may differ for each mounter 10. Therefore, in a mounter 10 that has a short processing time for a board 2, a non-operating period occurs during the execution of the production plan in which the mounting unit 5 does not operate (for example, the mounting unit 5 does not mount electronic components 4). In S18, the management device 8 judges whether or not there is a mounter 10 with a non-operating period based on the created production plan. If the management device 8 judges that there is a mounter 10 with a non-operating period (YES in S18), the process proceeds to S20, and if the management device 8 judges that there is no mounter 10 with a non-operating period (NO in S18), the process proceeds to S24.

[0040] In S20, the management device 8 judges whether or not an empty slot exists in the component mounter 10 identified in S18. The production plan transmitted to each component mounter 10 includes one or more jobs in which the type and number of electronic components 4 to be mounted on the board 2 are determined. Therefore, one or more component feeders 12 that accommodate the electronic components 4 corresponding to the job are attached to the feeder holding unit 14 of each component mounter 10. Here, since the feeder holding unit 14 has multiple slots, there may be a slot (empty slot) to which the component feeder 12 cannot be attached. In S20, the management device 8 judges whether or not this empty slot exists in the component mounter 10 identified in S18. If the management device 8 judges that an empty slot exists (YES in S20), the management device 8 proceeds to S22, and if the management device 8 judges that an empty slot does not exist (NO in S20), the management device 8 proceeds to S24.

[0041] In S22, the management device 8 transmits an imaging instruction to the control device 40 of the component mounter 10 identified in S18 to capture an image of the second component 4b during the non-operating period. The imaging instruction is an instruction independent of the production plan, and is not transmitted to component mounters 10 other than the component mounter 10 identified in S18. Specifically, the management device 8 transmits an instruction to the control device 40 of the component mounter 10 identified in S18 to attach the component feeder 12b containing the second component 4b to the feeder holding unit 14, and capture images of the second component 4b by the side imaging camera 20 and the bottom imaging camera 22 during the non-operating period.

[0042] In S24, the management device 8 judges whether or not an operation input for executing a process according to the created production plan has been received from the worker. If the management device 8 judges that the operation input has been received (YES in S24), in S26, the management device 8 transmits an execution instruction for executing a process according to the production plan to each mounter 10. After executing the process of S26, the management device 8 ends the series of processes.

[0043] Meanwhile, each mounter 10 that has received the execution instruction executes processing according to the job included in the production plan. Here, the control device 40 of the mounter 10 that has received the image capture instruction in S22 controls the loader 30 to attach the component feeder 12b that accommodates the second component 4b to an empty slot of the feeder holding unit 14. Then, the loader 30 attaches the component feeder 12b to the empty slot of the feeder holding unit 14, as shown by the arrow in Fig. 3. In Fig. 3, a plurality of component feeders 12 including the component feeder 12a that accommodates the first component 4a are attached to the feeder holding unit 14, and among the plurality of slots of the feeder holding unit 14, the two slots on the lower side of the drawing are empty slots.

[0044] Thereafter, when a non-operating period arrives while the control device 40 is executing a job included in the production plan, the control device 40 causes the nozzle 6 to pick up the second component 4b supplied from the component feeder 12b. Then, the control device 40 causes the side imaging camera 20 and the bottom imaging camera 22 to capture an image of the second component 4b picked up by the nozzle 6. Then, the control device 40 transmits the captured image of the second component 4b to the management device 8. Furthermore, when the control device 40 finishes capturing the image of the second component 4b, it controls the loader 30 to remove the component feeder 12b from the feeder holding unit 14. Meanwhile, the management device 8 that has received the image of the second component 4b creates component data for the second component 4b based on the image.

[0045] As described above, in the component mounter 10 of this embodiment, the period during which the mounting unit 5 is not operating (the period during which the mounting unit 5 does not mount electronic components 4) is calculated during the execution of the production plan, and images of the second components 4b (i.e., components not used in production) are captured during that period. Therefore, images of the second components 4b not used in production can be captured without reducing the production efficiency in the production line 100.

[0046] Moreover, in this embodiment, the second component 4b adsorbed to the nozzle 6 is imaged by the side imaging camera 20 and the bottom imaging camera 22. Therefore, images of the second component 4b can be acquired under the same imaging conditions as when the component is mounted on the board 2, and the reliability of the created component data is high.

[0047] In addition, in this embodiment, when imaging the second components 4b, the component feeder 12b is automatically attached to and detached from the feeder holding unit 14 by the loader 30. This eliminates the need for an operator to manually attach the component feeder 12b, improving convenience.

[0048] (Correspondence) The side imaging camera 20 and the bottom imaging camera 22 are an example of an "imaging unit." The memory of the control device 40 is an example of a "storage unit." The management device 8 and the control device 40 are an example of a "control unit." The non-operating period is an example of a "predetermined period." The board conveyor 26 is an example of a "transport unit." The loader 30 is an example of an "automatic placement mechanism."

[0049] In the above-described embodiment, the component feeder 12b containing the second components 4b is attached to and detached from the feeder holder 14 by the loader 30, but the component mounter 10 does not need to be equipped with the loader 30. In this case, the management device 8 may identify the component mounter 10 to which the component feeder 12b should be attached, and may display, for example, information indicating the position of the slot to which the component feeder 12b should be attached on the operation panel 28 of the identified component mounter 10. The worker may check the information and attach the component feeder 12b to an empty slot of the component mounter 10.

[0050] Furthermore, in the above embodiment, only the second component 4b is described as the subject of imaging, but images of a plurality of types of electronic components 4 may be captured during execution of the production plan.

[0051] In addition, the non-operating period does not have to be a period calculated based on a production plan. For example, when a certain mounter 10 has completed mounting of electronic components 4 on a board 2, but the post-processing in a downstream mounter 10 is delayed, a period occurs during which the board 2 on which mounting has been completed cannot be carried out. For this reason, for example, when the management device 8 receives information from the downstream mounter 10 that the post-processing is delayed, the management device 8 may control the mounter 10 to capture an image of the second components 4b during the period during which the board 2 cannot be carried out. That is, even if the determination is NO in S18 of FIG. 4, when the above information is received after executing S26, an image capture instruction may be transmitted. In this modification, the period during which the board 2 cannot be carried out is an example of a "predetermined period," and the information that the post-processing is delayed is an example of "predetermined information."

[0052] In addition, when the transportation of the board 2 is delayed due to an error or a pick-up error of the electronic components 4 in the upstream mounter 10, a period in which the board 2 is not carried into the mounter 10 occurs. For this reason, for example, when the management device 8 receives information from the upstream mounter 10 that the transportation of the board 2 is delayed due to an error or a pick-up error of the electronic components 4, the management device 8 may control the mounter 10 to capture an image of the second components 4b during the period in which the board 2 is not carried in. That is, even if the determination is NO in S18 of FIG. 4, if the above information is received after executing S26, an image capture instruction may be transmitted. In this modification, the period in which the board 2 is not carried in is an example of the "predetermined period," and the information that the transportation of the board 2 is delayed is an example of the "predetermined information."

[0053] Furthermore, there may be cases where the management device 8 determines in S18 that non-operating periods exist in multiple mounters 10, and determines in S20 that empty slots exist in multiple mounters 10. In such cases, the management device 8 may execute a process to identify, from among the multiple mounters 10, a mounter 10 equipped with a nozzle 6 optimal for picking up the second component 4b and cameras 20, 22 having optimal performance (resolution and lighting arrangement) for capturing an image of the second component 4b. Then, the management device 8 may transmit an image capture instruction to the identified mounter 10.

[0054] The technical elements described in this specification or drawings have technical utility either alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technologies illustrated in this specification or drawings achieve multiple objectives simultaneously, and achieving one of these objectives is itself technically useful.
