Description

Parts data creation system

[0001] The present disclosure relates to a component data creation system that creates component data used in the production of a board on which components are mounted.

[0002] In the field of component mounting, component mounting lines are widely known, in which multiple mounting devices are arranged in series to produce mounted boards on which components are mounted. When producing mounted boards using a component mounting line, component data for the components used in production must be prepared in advance. Conventionally, to avoid stopping the operation of the component mounting line, component data has been created using an offline camera unit installed offline outside the component mounting line and a host device connected to the offline camera unit (see, for example, Patent Document 1).

[0003] Patent Document 1 discloses a technology in which an operator places a target part on the part placement surface of a lift-up table provided in an offline camera unit, a camera provided above the lift-up table scans in a predetermined direction to acquire a part image, and a host device recognizes and processes the acquired part image to create part data.

[0004] Japanese Patent Application Publication No. 2015-144167

[0005] In the prior art including Patent Document 1, the position where the camera recognizes and identifies a component is determined to be near the center of the camera's image capture, and the range in which the component can be placed is limited. For example, the range in which the component can be placed is the center position of the lift table, which is vertically aligned with the center of the camera's image capture. However, with components becoming increasingly smaller in recent years, it has become extremely difficult for operators to place tiny components in specific positions, which increases the burden of component placement work and creates issues such as the need to frequently redo component placement, which requires a significant amount of time to create component data.

[0006] Therefore, an object of the present disclosure is to provide a component data creation system that can reduce the burden on the operator in component placement work.

[0007] The component data creation system disclosed herein is a component data creation system including a camera unit and a data creation device, wherein the camera unit includes a component placement table on which components are placed by an operator, and an imaging unit that images a predetermined search range of the component placement table, and the data creation device includes a component search unit that searches for the component from a search range image captured by the imaging unit, a component image extraction unit that extracts component images of a range that includes the component identified by the component search unit from the search range image, and a component data creation unit that creates component data for the component based on the component images extracted by the component image extraction unit.

[0008] According to the present disclosure, the burden on the operator of component placement work can be reduced.

[0010] An embodiment of the present disclosure will be described in detail below with reference to the drawings. The configurations, shapes, and the like described below are merely examples for explanatory purposes and can be modified as appropriate depending on the specifications of the component mounting system, upper system, mounting line, component mounting device, and the like. Corresponding elements in all the drawings will be denoted by the same reference numerals, and redundant description will be omitted. In a given drawing, two axes perpendicular to each other in a horizontal plane are shown: an X-axis in the substrate transport direction (the up-down direction in FIG. 1 ), and a Y-axis perpendicular to the substrate transport direction (the left-right direction in FIG. 1 ). Furthermore, a Z-axis (the up-down direction in FIG. 3 ) is shown as the height direction perpendicular to the horizontal plane.

[0011] First, a schematic configuration of a component mounting system 1 will be described with reference to FIG. 1 . FIG. 1 is an overall configuration diagram showing an overview of a component mounting system according to an embodiment of the present disclosure. The component mounting system 1 has a function of printing solder paste on a board 3 to mount components 2 (see also FIG. 2 ). The component mounting system 1 includes a mounting line ML on which multiple mounting devices are arranged along the X-axis direction, which is the board transport direction, and a higher-level system 5 (host device) connected offline to the multiple mounting devices via a wired or wireless communication network 4. In this specification, "offline" refers to a position outside the work line where various operations are performed to mount components 2 on boards 3 transported along the board transport direction to produce mounted boards.

[0012] A camera unit 6, which is used to create component data (described later), is connected to the host system 5 via the communication network 4. Like the host system 5, the camera unit 6 is also installed offline, so the camera unit 6 can also be called an offline camera unit. In this embodiment, the component mounting system 1 will be referred to as including the camera unit 6.

[0013] The camera unit 6 captures an image of the component 2 for which component data is to be created. The host system 5 acquires image data of the component 2 captured by the camera unit 6 via the communication network 4 and creates predetermined component data by performing recognition processing on the image data. The host system 5 functions as a data creation device that creates component data. The host system 5 and the camera unit 6 together constitute a component data creation system 100 that creates component data. The detailed structure of the camera unit 6 will be described later.

[0014] Next, the mounting line ML will be described. In Fig. 1, the mounting line ML is configured by connecting, in the X-axis direction, mounting devices such as a board supply device M1, a screen printing device M2, multiple component mounting devices M3 and M4, an inspection device M5, a reflow device M6, and a board removal device M7, from upstream (upper side of the drawing) to downstream (lower side of the drawing) in the board transport direction. Boards 3 are delivered to and from each mounting device by a transport conveyor arranged along the X-axis direction.

[0015] The board supplying device M1 has a storage unit such as a rack for storing a plurality of boards 3, and performs the work of removing the boards 3 from the storage unit and supplying them to the screen printing device M2. The screen printing device M2 performs the work of aligning a screen mask above the boards 3 carried in from upstream, and printing solder on the electrode portions of the boards 3 by sliding a squeegee over the screen mask on which paste solder has been previously supplied.

[0016] The component mounting devices M3 and M4 use suction nozzles attached to their work heads to pick up components 2 supplied by component supply units such as tape feeders or tray feeders, and mount the components 2 on solder-printed boards 3. The inspection device M5 uses a mounting inspection work unit including an inspection camera to inspect the position and state of the components 2 mounted on the board 3.

[0017] The reflow device M6 heats the board 3 carried into the device using a board heating unit, melting and solidifying the solder on the board 3 and joining the electrode parts of the board 3 to the terminals of the components 2. The board recovery device M7 has a storage unit such as a rack that stores multiple boards 3, and receives the boards 3 carried out by an upstream device and recovers them in the storage unit.

[0018] The component data created by the higher-level system 5 is referenced during component mounting operations by component mounting devices M3 and M4 and during mounting state inspection operations by inspection device M5. The mounting line ML in this embodiment is an example, and may incorporate an inspection device for inspecting the state of the solder printed on the board 3, or an inspection device for inspecting the state of the board 3 after reflow, etc. Furthermore, the component mounting devices M3 and M4 may be equipped with various inspection functions. Furthermore, the number of component mounting devices arranged on one mounting line ML is arbitrary.

[0019] Next, the configuration of component mounting devices M3 and M4 will be described with reference to Figure 2. Figure 2 is a schematic plan view of a component mounting device constituting a component mounting system according to an embodiment of the present disclosure. A board transport mechanism 8 including a pair of transport conveyors extending in the X-axis direction is provided on the upper surface of a base 7. Component supply units 9 are disposed on both sides of the board transport mechanism 8, and a plurality of tape feeders 10 are set in the component supply unit 9. The tape feeders 10 pitch-feed a carrier tape holding components 2 to be mounted, thereby supplying the components 2 to a pickup position for a mounting head 11, which will be described later.

[0020] A Y-axis movement mechanism 12 equipped with a linear drive mechanism is disposed in the Y-axis direction at one end in the X-axis direction on the upper surface of the base 7. Two X-axis movement mechanisms 13 are attached to the Y-axis movement mechanism 12 so as to be movable in the Y-axis direction, and a mounting head 11 is attached to each X-axis movement mechanism 13 so as to be movable in the X-axis direction by the linear drive mechanism.

[0021] The mounting head 11 is a multiple head equipped with a plurality of unit transfer heads 11a (four in this example), and a suction nozzle (not shown) for suctioning components is attached to the lower end of each unit transfer head. By driving the Y-axis movement mechanism 12 and the X-axis movement mechanism 13, the two mounting heads 11 move in the X-axis and Y-axis directions, and the suction nozzles pick up components 2 from the desired component supply units 9 and mount them on the board 3 positioned and held at the mounting work position.

[0022] A component recognition camera 14 is provided with its imaging surface facing upward along the movement path of the mounting head 11. When the mounting head 11 holding the component 2 by the suction nozzle moves above the component recognition camera 14, the component recognition camera 14 captures an image of the component 2 held by the suction nozzle.

[0023] A board recognition camera 15, which moves integrally with the mounting head 11, is provided on the underside of the X-axis movement mechanism 13 with its imaging surface facing downward. The board recognition camera 15 moves above the board 3 together with the mounting head 11 and captures images of component mounting points set on the board 3. The mounting operation of the component 2 by the mounting head 11 is performed after the mounting head 11 has positioned the component 2 based on the recognition results obtained by recognition processing of image data by the component recognition camera 14 and the board recognition camera 15.

[0024] Next, the camera unit 6 constituting the component data creation system 100 will be described with reference to FIGS. 3 and 4 . FIG. 3 is a schematic perspective view of the camera unit constituting the component data creation system according to an embodiment of the present disclosure. FIG. 4 is a schematic front view of the camera unit constituting the component data creation system according to an embodiment of the present disclosure. The camera unit 6 is configured to include various elements, including a tray loading stage 26 and a camera 19, inside a housing 17. The housing 17 is configured to include a base 20, standing portions 21 that stand upright from both sides and the back of the base 20, and a cover portion 22 provided on the upper part of the standing portions 21 so as to cover the base 20 from above. The interior of the housing 17 is partially open.

[0025] On the base 20, an X-axis moving table 23, a Y-axis moving table 24, a Z-axis moving table 25, and a tray loading stage 26 are stacked in this order from the bottom. By driving the X-axis moving table 23, the Y-axis moving table 24, and the Z-axis moving table 25, the tray loading stage 26 moves in the X-axis, Y-axis, and Z-axis directions. The X-axis moving table 23, the Y-axis moving table 24, and the Z-axis moving table 25 form stage moving means that move the tray loading stage 26 in a predetermined direction. The tray loading stage 26 is open to the outside, allowing easy access by an operator.

[0026] Any means may be used to move the tray loading stage 26 in a predetermined direction, and for example, a link mechanism that is manually operated by an operator may be used as a means for moving it in the Z-axis direction. Also, a slide mechanism equipped with a slider that can slide along a guide rail may be used as a means for moving it in the X-axis direction and the Y-axis direction, and the tray loading stage 26 may be manually moved by an operator.

[0027] The camera 19 is located above the tray mounting stage 26 and is attached to the cover portion 22 with its imaging surface 19a facing downward toward the tray mounting stage 26. The camera 19 captures images of the components 2 on the tray 27 mounted on the tray mounting stage 26. When capturing an image with the camera 19, the components 2 on the tray 27 are illuminated by an illumination device (not shown) provided in the camera unit 6. For convenience, part of the camera 19 is not shown in Figure 3. It is desirable that the camera 19 be the same as the component recognition camera 14 provided in the component mounting devices M3 and M4. The camera 19 is installed upside down relative to the component recognition camera 14 (the orientation of the imaging surface is different).

[0028] A tray 27 is mounted on the tray mounting stage 26 as a component mounting table on which an operator places components 2. In Fig. 5, the tray 27 includes a tray main body 28 that is substantially rectangular in plan view, a frame member 29 that holds the outer edge of the tray main body 28 so as to cover it, and a gripper 30 provided on one side of the frame member 29. At least a front end 29a of the frame member 29 is made of a metal (such as iron) that is attracted to a magnetic member such as a magnet.

[0029] The upper surface of the tray main body 28 is a component placement surface 28a on which the components 2 are placed, and at least the component placement surface 28a, which is the upper surface (front surface) of the tray main body 28, is made of a material (e.g., rubber) that has a high coefficient of friction with the components 2 to be placed on it. By making the component placement surface 28a out of a rubber material, the components 2 placed on the component placement surface 28a are prevented from slipping. The gripping portion 30 has an opening 30a through which the operator's fingers are inserted, and the operator can mount the tray 27 on the tray loading stage 26 while gripping the gripping portion 30.

[0030] 5 is a schematic plan view of a tray used in a component data creation system according to an embodiment of the present disclosure. In FIG. 5 , a plurality of visible straight lines are marked on the component placement surface 28a of the tray body 28. More specifically, the component placement surface 28a is marked with two intersecting (more precisely, perpendicular) reference lines L1 and L2 that pass through the center of the tray 27 in a plan view. The position where the two reference lines L1 and L2 intersect, i.e., the tray center position C, corresponds to the imaging center of the camera 19. When the tray 27 is attached to the tray attachment stage 26, the imaging center of the camera 19 and the tray center position C coincide in the vertical direction.

[0031] Two first component placement reference lines L3 are provided on the tray 27, extending parallel to the reference line (horizontal direction) L2 and sandwiching the tray center position C. Each of the two first component placement reference lines L3 is positioned at an equal distance from the tray center position C. The first component placement reference lines L3 define the area on the component placement surface 28a on which a component 2 of a predetermined size (first component 2a shown in FIG. 8A) can be placed.

[0032] The tray 27 is further provided with two second component placement reference lines L4 extending parallel to the reference line (horizontal direction) L2 and sandwiching the tray center position C. Each of the multiple second component placement reference lines L4 is positioned at equal intervals from the tray center position C and is positioned at a distance greater than the distance between the two first component placement reference lines L3. The second component placement reference lines L4 define the area on the component placement surface 28a on which a component 2 of a predetermined size (a second component 2b shown in FIG. 8(b) that is larger than the first component 2a) can be placed.

[0033] 3, the structure for mounting the tray 27 on the tray mounting stage 26 will be described. A pair of guide members 31 are arranged on the tray mounting stage 26 at a distance corresponding to the lateral size of the tray 27. The pair of guide members 31 extend in the mounting direction (arrow a) of the tray 27, and guide the tray 27 from both sides when the tray 27 is mounted.

[0034] A stopper 32 having a pressing surface on its underside is provided on the rear end side of the pair of guide members 31 on the tray loading stage 26. The stopper 32 is located approximately in the center of the pair of guide members 31. Two magnetic members 33 are provided on each side of the stopper 32. As the tray 27 slides on the tray loading stage 26 along the pair of guide members 31, the front side of the tray 27 abuts against the stopper 32 and the magnetic member 33, restricting further movement. At this time, the front end 29a (FIG. 5) of the frame member 29 constituting the tray 27 is made of metal and is therefore attracted to the magnetic member 33. As a result, the tray 27 is positioned and fixed at a predetermined position on the tray loading stage 26. Note that upward movement of the tray 27 is restricted by the pressing surface of the stopper 32.

[0035] Next, the configuration of the control system of the component data creation system 100 will be described with reference to FIG. 6 . FIG. 6 is a block diagram showing the configuration of the control system of the component data creation system according to an embodiment of the present disclosure. The control unit 34 of the host system 5 includes a communication unit 35, a storage unit 36, a component search unit 37, a component image extraction unit 38, and a component data creation unit 39. The control unit 40 of the camera unit 6 includes a communication unit 41 and an image acquisition unit 42. The control unit 34 of the host system 5 is connected to a display unit 43 such as a monitor and an operation / input unit 44 such as a keyboard or mouse. Note that a touch panel in which the display unit 43 and the operation / input unit 44 are integrated may also be used.

[0036] The communication unit 35 transmits and receives various data to and from the camera unit 6 and a predetermined mounting device. The storage unit 36 ​​stores component data 45, search range data 46, and the like. The component data 45 includes, for each type of component 2, the component name, size information such as the component's length, width, and thickness, and identification information indicating the category of the component 2. The search range data 46 is a search range set for each size of the component 2 when searching for the component 2 from the image data acquired by the camera 19.

[0037] FIG. 7 is a diagram illustrating search range data used in a component data creation system according to an embodiment of the present disclosure. FIG. 7 illustrates an example of search range data 46. The search range data 46 is configured by linking "Component" 47, "Component Size" 48, and "Search Range" 49. "Component" 47 is information identifying the type of component using a component name, identification number, or the like. "Component Size" 48 indicates the vertical or horizontal size of the component 2. In this embodiment, the components 2 are classified based on their content, including components 2 (first components 2a) whose vertical size is in the range of less than 45 mm and components 2 (second components 2b) whose vertical size is in the range of 45 mm or more and less than 90 mm.

[0038] "Search range" 49 indicates the search range for components 2 set for each size of the classified components 2. Figures 8(a) and 8(b) show examples of search ranges set on the component placement surface 28a of the tray 27, and also show examples in which components 2 (first component 2a in Figure 8(a) and second component 2b in Figure 8(b)) are displayed in the search ranges.

[0039] 8A and 8B are diagrams illustrating a component search range of a camera unit according to an embodiment of the present disclosure. As shown in FIG. 8A , for example, for a first component 2a, the component 2 is searched for based on an image (first search range image) of a first search range R1 (the range indicated by hatching) defined by two first component placement reference lines L3 parallel to a reference line (horizontal) L2 marked on the tray 27 and two vertical search lines L5 parallel to a reference line (vertical) L1. In this embodiment, each of the two vertical search lines L5 coincides with two sides of the component placement surface 28a. Thus, two parallel straight lines (first component placement reference lines L3) indicating two sides of the rectangular search range are marked on the tray 27.

[0040] 8(b), for the second component 2b, the component 2 is searched for based on an image (second search range image) of a second search range R2 (the range indicated by hatching) defined by two second component placement reference lines L4 parallel to the reference line (horizontal) L2 marked on the tray 27 and the two vertical search lines L5 described above. In other words, the larger the size of the component 2, the wider the search range. The first search range image and the second search range image are acquired by imaging using the camera 19.

[0041] Thus, in this embodiment, tray 27 is marked with at least four parallel lines (first component placement reference line L3 and second component placement reference line L4) that indicate two sides of each of a plurality of rectangular search ranges that have the same center (tray center position C) but different sizes. Tray 27 is also marked with two lines (vertical reference line L1 and horizontal reference line L2) that intersect (are perpendicular to) each other at the center of the search range. Furthermore, camera 19 serves as an imaging unit that captures an image of the predetermined search range of tray 27.

[0042] In this embodiment, the first search range R1 and the second search range R2 are illustrated as two patterns with different sizes, but the search ranges may be divided into three or more patterns with different sizes depending on the size of the components 2. In such a case, similar to the first component placement reference line L3 and the second component placement reference line L4, two nth component placement reference lines extending parallel to the reference line (horizontal direction) L2 on either side of the tray center position C are provided on the tray body 28.

[0043] The component search unit 37 determines a predetermined search range from among a plurality of preset search ranges based on the size information of the component 2 selected by the operator via the display unit 43 and the operation / input unit 44 and the search range data 46, and executes processing to search for the component 2 from the search range image acquired by the camera 19. In other words, the component search unit 37 searches for the component 2 from the search range image captured by the camera 19. The host system 5 also varies the size of the search range depending on the size of the component 2.

[0044] 9 is a diagram showing a component size selection screen displayed on a display unit constituting a component data creation system according to an embodiment of the present disclosure. Fig. 9 shows a component size selection screen 50 displayed on the display unit 43 when creating component data 45. The component size selection screen 50 displays a drop-down list 51 from which the size of the component 2, classified within a predetermined range, can be selected. The operator selects the desired size by manipulating a pointer 52 via the operation / input unit 44. When the operator clicks a "Decide" button 53 displayed on the component size selection screen 50, the display on the display unit 43 switches to a component placement guidance screen 54 shown in Fig. 10.

[0045] FIG. 10 is a diagram illustrating a component placement guide screen displayed on a display unit constituting a component data creation system according to an embodiment of the present disclosure. In FIG. 10 , the component placement guide screen 54 displays an image display field 55 displaying an image of the tray 27, and also highlights the area in which the component 2 can be placed. Examples of highlighting include coloring the area in which the component 2 can be placed or applying hatching. Furthermore, the component placement guide screen 54 displays a text display field 56 that instructs the user, using text data, on the area in which the component 2 can be placed. In this embodiment, the text displayed is, "Please place the component in the area indicated by the hatching." The operator can place the component 2 in the appropriate area by visually checking the image of the tray 27 displayed in the image display field 55. After placing the component, the operator can click the "Done" button 57 displayed on the component placement guide screen 54 with the pointer 52, causing the camera 19 to capture an image of the component 2.

[0046] The component image extraction unit 38 executes a process of extracting component images by performing a recognition process on the search range image on the component placement surface 28a obtained by capturing an image using the camera 19. One method of recognition processing is to perform a binarization process on the search range image to separate it into black and white, and distinguish between the component placement surface 28a and the rest (components 2). In other words, the component image extraction unit 38 extracts component images of a range that includes the position of the component 2 identified by the component search unit 37 from the search range image.

[0047] The component data creation unit 39 creates component data 45 for the component 2 based on the component image extracted by the component image extraction unit 38. For example, the component data creation unit 39 detects the basic shape, vertical and horizontal sizes (length dimensions), terminal positions, etc. of the component 2 from the component image, and creates the component data 45 by linking this information to the component identification information.

[0048] The communication unit 41 included in the camera unit 6 transmits image data captured by the camera 19 to the host system 5. The image acquisition unit 42 controls the stage movement means to perform a scanning operation to acquire a predetermined search range image while moving the tray 27 on which the components 2 are placed relative to the camera 19. The image acquisition unit 42 generates the search range image by combining the divided images captured at each position. In addition, the control unit 40 controls the movement of each table by driving the X-axis moving table 23, the Y-axis moving table 24, and the Z-axis moving table 25.

[0049] The component data creation system 100 according to the present embodiment is configured as described above. Next, a component data creation method will be described with reference to the flowchart shown in FIG. 11. FIG. 11 is a flowchart of the component data creation method according to an embodiment of the present disclosure. When creating component data 45, the operator mounts the tray 27 on the tray mounting stage 26 in advance.

[0050] First, the upper system 5 determines whether or not a component size has been selected by the operator through the component size selection screen 50 (FIG. 9) (ST (step) 1: component size selection determination step). That is, the upper system 5 determines whether or not the operator has selected a component size through the component size selection screen 50 and then clicked the "OK" button 53. In this embodiment, the size corresponding to the first component 2a is selected.

[0051] Once the component size has been selected (Yes in ST1), the host system 5 displays the component placement guide screen 54 ( FIG. 10 ) on the display unit 43 ( ST2: component placement screen display step). The operator places the first component 2a in the first search range R1, which is displayed hatched in the image display field 55 ( FIG. 8( a)). At this time, the operator does not need to place the first component 2a at the tray center position C; the operator may place the first component 2a anywhere within the first search range R1.

[0052] After placing the first component 2a, if the operator clicks the "Done" button 57 displayed on the component placement guidance screen 54, the control unit 40 of the camera unit 6 adjusts the focus of the camera 19 before the camera 19 captures an image of the first component 2a (ST3: focus adjustment step). This step is performed by the control unit 40 driving and controlling the Z-axis moving table 25 to raise and lower the tray loading stage 26 and adjust the relative position of the camera 19 and the component 2. In a structure in which the operator manually adjusts the height of the tray loading stage 26, for example, the control unit 40 may notify the operator that the image is out of focus using a notifying unit (not shown) and stop notifying the operator when the image is in focus.

[0053] After the focus adjustment, the camera 19 captures an image of the search range (first search range R1) corresponding to the size of the selected first component 2a (ST4: imaging step). That is, the image acquisition unit 42 drives the X-axis moving table 23 and the Y-axis moving table 24 to move the tray 27 mounted on the tray mounting stage 26 in the X-axis and Y-axis directions (scanning operation), while the camera 19 captures divided images of each position of the tray 27 corresponding to the first search range R1. The image acquisition unit 42 generates a first search range image 58 ( FIG. 12 ) by combining multiple image data acquired by imaging. Note that, if the X-axis moving table 23 and the Y-axis moving table 24 are manually moved by an operator, the control unit 40 notifies the operator of the timing of manual operation before capturing an image with the camera 19. Note that if the imaging range of the camera 19 is larger than the search range, the scanning operation may not be performed.

[0054] Next, the component search unit 37 searches for the component 2 (image of the first component 2a) from the first search range image 58 (ST5: component search step). Next, the component image extraction unit 38 extracts a component image 58a ( FIG. 12 ) of a range T including the first component 2a identified by the component search unit 37 from the first search range image 58 (ST6: component image extraction step). FIG. 12 is a diagram illustrating a search range image according to an embodiment of the present disclosure.

[0055] Next, the component data creation unit 39 performs a recognition process on the extracted component image 58a (ST7: recognition process step). Then, based on the results of the recognition process on the component image 58a, the component data creation unit 39 detects the basic shape, vertical and horizontal sizes, terminal positions, etc. of the first component 2a, and creates component data 45 that links this information with component identification information (ST8: component data creation step). The created component data 45 is stored in the storage unit 36 ​​and is referenced when various tasks are performed by the component mounting devices M3 and M4 and the inspection device M5.

[0056] As described above, the component data creation system 100 according to this embodiment can widen the area in which components 2 can be placed, thereby reducing the burden on the operator in placing components. It can also eliminate delays in creating component data 45 due to the need to redo component placement.

[0057] The component data creation system 100 of the present disclosure is not limited to the embodiments described above, and design modifications may be made without departing from the spirit of the invention. For example, instead of providing the storage unit 36 ​​in the host system 5, an external storage device connected to the host system 5 may be provided separately. Furthermore, the various internal processing functions (component search unit 37, component image extraction unit 38, component data creation unit 39, image acquisition unit 42, etc.) provided in the host system 5 and the camera unit 6 may be provided in either the host system 5 or the camera unit 6.

[0058] This application is based on a Japanese patent application (Patent Application No. 2024-087206) filed on May 29, 2024, the contents of which are incorporated herein by reference.

[0059] According to the present disclosure, the burden on the operator of component placement work can be reduced.
