Embodiment 1-1. Configuration example for the production line WL0

[0010] The screen fixing device 70 can be applied to at least one production line WL0, which has at least one panel processing machine WM0. As shown in Fig. Figure 1 shows that a production plant of one embodiment comprises two production lines WL0, including a first production line WL1 and a second production line WL2.

[0011] In each of the two production lines WL0, at least one (five in the drawing) plate processing machine WM0 performs a predetermined plate processing operation on the circuit board 90. The type and number of plate processing machines WM0 that make up production line WL0 are not limited. As shown in Fig. As shown in Figure 1, the production line WL0 of the embodiment comprises several plate processing machines WM0, namely a printing machine WM1, a print inspection machine WM2, a component placement device WM3, a reflow oven WM4 and a visual inspection device WM5, and the plate 90 is transported by a printed circuit board transport device in the sequence described above.

[0012] The printing machine WM1 prints solder onto the mounting positions of several components on the printed circuit board 90. The print inspection device WM2 checks the print condition of the solder printed by the printing machine WM1. As shown in Fig. As shown in Figure 2, the component placement device WM3 mounts several components onto the printed circuit board 90, onto which the solder was printed by the printing machine WM1. The number of component placement devices WM3 can be one or more. If several component placement devices WM3 are present, they can share the task of mounting multiple components.

[0013] The reflow oven WM4 heats the printed circuit board (PCB) 90, onto which several components have been mounted by the component placement device WM3, melts the solder, and performs the soldering process. The visual inspection device WM5 checks the mounting status, etc., of several components that have been mounted by the component placement device WM3. In this way, the production line WL0 can transport the PCB 90 in the correct sequence using the board processing machine WM0 and perform a production process, including an inspection process, to manufacture the finished product board 900. Depending on requirements, the production line WL0 can include board processing machines WM0 such as a functional testing device, a buffer device, a PCB feeder, a PCB flipper, a shielding assembly device, an adhesive application device, and a UV irradiation device.

[0014] At least one plate processing machine WM0, forming the production line WL0, and the line management device LC0 are connected in such a way that they can communicate with each other via a communication section. The line management device LC0 and the management device HC0 are also connected in such a way that they can communicate with each other via the communication section. The communication section simply needs to be capable of connecting the plate processing machine WM0 and the line management device LC0, as well as the line management device LC0 and the management device HC0, via wired or wireless communication, whereby the communication method can take various forms.

[0015] In this embodiment, several plate processing machines WM0, a line management device LC0, and an administration device HC0 form a local area network (LAN). This allows several plate processing machines WM0 to communicate with each other via the communication interface. Furthermore, several plate processing machines WM0 can communicate with the line management device LC0 via the communication interface. Additionally, the line management device LC0 and the administration device HC0 can communicate with each other via the communication interface.

[0016] The line management device LC0 controls several plate processing machines WM0, which form the production line WL0, and monitors the operating status of the production line WL0. The line management device LC0 stores various types of control data for controlling the several plate processing machines WM0. The line management device LC0 transmits control data to each of the several plate processing machines WM0. In addition, each of the several plate processing machines WM0 transmits its operating status and a production status to the line management device LC0. The management device LC0 manages at least one (in Fig. 1. Two) Line management device LC0. For example, the operating status and production status of the plate processing machine WM0, as recorded by the line management device LC0, are transferred to the management device HC0 and managed as needed. 1-2. Configuration example for the component placement device WM3

[0017] The WM3 component placement device secures several components onto the 90° printed circuit board. As shown in Fig. As shown in Figure 2, the component placement device WM3 of the embodiment has two sets of component placement devices 50, 50, each comprising a printed circuit board transport device 10, a component feeding device 20, a component transfer device 30, a parts camera 41, a printed circuit board camera 42, a nozzle station 43 and a protective cover 44 as well as a control device 45.

[0018] The two sets of component placement devices 50, 50 have a common structure and are arranged so that they are opposite each other on the same base.

[0019] For the sake of simplicity, in the present description, a side on which one of the two sets of component placement devices 50, 50 is arranged (for example, the underside of the paper surface of Fig. 2), is defined as the first side S1. Furthermore, a side on which the other of the two sets of component placement devices 50, 50 is arranged (for example, the top of the paper surface in Fig. 2), defined as the second side S2. Furthermore, the component placement device 50 arranged on the first side S1 is referred to as component placement device 50a, and the component placement device 50 arranged on the second side S2 is referred to as component placement device 50b.

[0020] As described above, in the Fig. In the component placement device WM3 shown in Figure 2, to identify the components of the two sets of component placement devices 50, an "a" is appended to the end of the reference number of the component located on the first side S1 and a "b" to the end of the reference number of the component located on the second side S2. In this description, the conveying direction of the printed circuit board 90 is defined as the X-direction. Furthermore, a direction orthogonal to the conveying direction (X-direction) in the horizontal plane in which the two sets of component placement devices 50 are located opposite each other is defined as the Y-direction. Finally, a vertical direction orthogonal to the conveying direction (X-direction) and to the opposite direction (Y-direction) is defined as the Z-direction.

[0021] The printed circuit board transport device 10 has transport mechanisms 11 arranged side by side in the opposite direction (Y-direction). The transport mechanism 11 comprises a pair of guide rails 12 and a conveyor belt 13. Each of the two guide rails 12 extends along the conveying direction (X-direction) of the printed circuit board 90 and can support the edge region of the printed circuit board 90 placed on and conveyed on the conveyor belt 13. At least one of the two guide rails 12 is arranged on the base such that it is movable along the opposite direction (Y-direction).

[0022] The printed circuit board transport device 10 conveys the printed circuit board 90 in the conveying direction (X-direction). The printed circuit board 90 is a circuit board on which an electronic circuit, an electrical circuit, a magnetic circuit, and the like are formed. The printed circuit board transport device 10 transports the printed circuit board 90 into the component placement device 50 and positions the printed circuit board 90 at a predetermined position in the component placement device 50. After an assembly operation of several components by the component placement device 50 is completed, the printed circuit board transport device 10 transports the printed circuit board 90 out of the component placement device 50.

[0023] The component feeder 20 feeds components to be mounted on the printed circuit board 90. The component feeder 20 has several slots 21 and several roller holder sections 22. The slots 21 and roller holder sections 22 are arranged along the conveying direction (X-direction) of the printed circuit board 90. A feeder 23 is removably provided in each of the slots 21. The feeder 23 indexes a carrier belt, which holds components, in a single step to feed the components so that they can be picked up at a feed position at the distal end of the feeder 23. The roller holder section 22 holds a replaceable roller onto which the carrier belt is wound. Furthermore, the component feeder 20 can also hold an electronic component (e.g., a microcontroller).a connection of the component or the like) which is relatively large compared to a chip component or the like and is arranged on a shell.

[0024] The component transfer device 30 transfers the component supplied by the component feeder 20 to a predetermined mounting position on the printed circuit board 90, which is transported by the printed circuit board transport device 10 into the component placement device 50. The component transfer device 30 has a head drive device 31 and a motion table 32. The head drive device 31 moves the motion table 32 in a horizontal direction (conveyor direction (X-direction) and counter-direction (Y-direction)) by means of the linear motion mechanism. The mounting head 33 is detachably (replaceably) attached to the motion table 32 by a clamping element.

[0025] Various tools are detachably (interchangeably) attached to the mounting head 33. These tools include, for example, a suction nozzle 34 and a chuck. The suction nozzle 34 picks up the component and holds it securely using supplied vacuum air. The lifting and lowering position and angle of the suction nozzle 34 relative to the mounting head 33, as well as the vacuum air supply status, are controlled by the control device 45 described later. Furthermore, a chuck for clamping a component can be detachably (interchangeably) attached to the mounting head 33.

[0026] As described above, the component placement device WM3 of the embodiment has a facing robot in which two assembly heads 33 (assembly head 33a and assembly head 33b) are arranged opposite each other. The movable areas of the two assembly heads 33 overlap, and the two assembly heads 33 are configured so that they are accessible from a side (in this case, the second side S2) opposite a side (for example, the first side S1, on which assembly head 33a is provided) on which the assembly heads 33 are provided. Therefore, the two assembly heads 33 can work alternately on the same circuit board 90. Non-interference control is implemented on the two assembly heads 33 by the control device 45 so that they do not interfere with each other in the area where the movable areas overlap.

[0027] Known imaging devices can be used as the part camera 41 and the printed circuit board camera 42. The part camera 41 is mounted on a base of the component placement device WM3 such that its optical axis points upwards in the vertical direction (Z-direction). The part camera 41 can, for example, image a component held by the suction nozzle 34 from below. The printed circuit board camera 42 is arranged on the motion table 32 of the component transfer device 30 such that its optical axis points downwards in the vertical direction (Z-direction). The printed circuit board camera 42 can image the printed circuit board 90 or the like from above. The part camera 41 and the printed circuit board camera 42 perform the imaging based on a control signal sent by the control device 45. The image data of the images acquired by the part camera 41 and the printed circuit board camera 42 are transmitted to the control device 45.

[0028] The nozzle station 43 is provided in the component placement device WM3. For example, the nozzle station 43 is detachably (interchangeably) attached to the base of the component placement device WM3. The nozzle station 43 is a tool station that accommodates various tools used for processing the printed circuit boards of the component placement device WM3. The nozzle station 43 can, for example, detachably hold several suction nozzles 34.

[0029] During a replacement process of the suction nozzle 34, the nozzle station 43 holds the suction nozzle 34 removed from the assembly head 33 and holds a different suction nozzle 34 in a removable manner. Accordingly, the component placement device WM3 can automatically replace the suction nozzle 34 according to the type of component to be mounted, for example, during the execution of the assembly process.

[0030] The protective cover 44 protects the worker. As in Fig. As shown in Figure 2, the protective cover 44 can cover the entire component placement device 50, which includes a component feeder 20. For example, if the worker is performing work on the component placement device 50a on the first side S1, he opens and closes the protective cover 44a on the first side S1 and performs the work on the component placement device 50a. Similarly, if the worker is performing work on the component placement device 50b on the second side S2, he opens and closes the protective cover 44b on the second side S2 and performs the work on the component placement device 50b.

[0031] The control device 45 comprises a known computing device and storage device and forms a control circuit. Information, image data, and the like, output by various sensors provided in the component placement device WM3, are input into the control device 45. The control device 45 sends control signals to each device based on a control program, a predefined placement condition, and the like.

[0032] For example, the control device 45 causes the printed circuit board camera 42 to image the printed circuit board 90 positioned by the printed circuit board transport device 10. The control device 45 performs image processing of the image captured by the printed circuit board camera 42 to detect the positioning state of the printed circuit board 90. Furthermore, the control device 45 causes, for example, the suction nozzle 34 to pick up and hold the component fed by the component feeder 20, and causes the part camera 41 to image the component held by the suction nozzle 34. The control device 45 performs image processing of the image captured by the part camera 41 to detect the holding position of the component.

[0033] The control device 45 moves the suction nozzle 34 past a planned mounting position, which was previously defined by a control program or the like. Furthermore, based on the positioning status of the circuit board 90, the holding position of the component, and the like, the control device 45 corrects the planned mounting position to determine the mounting position where the component is actually attached. In addition to a position (X-coordinate and Y-coordinate), the planned mounting position and the actual mounting position also have a rotation angle. The control device 45 corrects a target position (X-coordinate and Y-coordinate) and the rotation angle of the suction nozzle 34 according to the mounting position. The control device 45 lowers the suction nozzle 34 with the corrected rotation angle at the corrected target position to attach the component to the circuit board 90.

[0034] The control device 45 repeats the pick-up and placement cycle described above to perform the assembly process of attaching multiple components to the printed circuit board 90. The total time required for a predetermined number of cycles of the pick-up and placement cycle described above, and the time required for inserting and removing the printed circuit board 90, corresponds to one cycle time per printed circuit board 90. 1-3. Configuration example for the screen fixing device 70

[0035] As in Fig. As shown in Figure 2, the plate processing machine WM0 has several (two in the drawing) screens 60, which allow the operator to control the plate processing machine WM0 using a single display. For example, the operator authorization for the plate processing machine WM0 is configured such that operation using at least one screen 60 from several (two) screens 60, and operation using at least one other screen 60 from several (two) screens 60, do not conflict with each other.

[0036] In the configuration described above, if the operator authorization for operating the WM0 plate processing machine is switched, and this is done, for example, via a mechanical switch, the aging of the mechanical switch may lead to a malfunction during the authorization switchover. Furthermore, since a wiring harness is required to connect the mechanical switch and the control device 45, there is a possibility that manufacturing and maintenance costs will increase.

[0037] Therefore, the production plant is equipped with a screen locking device 70. The screen locking device 70 has several screens 60 and 60 and a locking section 71. Accordingly, the screen locking device 70 can lock the screen 60, which has operator authorization to operate the panel processing machine WM0, onto the display 61. The screen locking device 70 can have an identification section 72. The locking section 71 and the identification section 72 can be provided in different control devices and management devices. For example, at least one of the locking section 71 and identification section 72 can be provided in the control device of the panel processing machine WM0 (for example, the control device 45 in the component placement device WM3).

[0038] At least one of Determination Section 71 and Identification Section 72 may be provided in the Line Management Device LC0. At least one of Determination Section 71 and Identification Section 72 may be provided in the Management Device HC0. At least one of Determination Section 71 and Identification Section 72 may be configured in a cloud. As described in Fig. As shown in Figure 3, in this embodiment, the fixing section 71 and the identification section 72 are provided in the control device 45 of the component placement device WM3. The aspects described in this description can be selected and applied as appropriate. Furthermore, the aspects described in this description can be combined as appropriate. 1-3-1. Multiple screens 60 and setting section 71

[0039] Several (two in the Fig. 2 and Fig. 3) Screens 60, 60 can be any known screens, as long as the worker can operate the plate processing machine WM0 on the display 61. For example, a screen that has a touch panel can be used as multiple (two) screens 60, 60.

[0040] Each panel processing machine WM0 can be equipped with multiple (two) screens 60, 60. Each production line WL0 can be equipped with multiple (two) screens 60, 60. Multiple (two) screens 60, 60 can also be provided in a portable terminal or similar device carried by the operator. Multiple (two) screens 60, 60 of this embodiment are provided for each panel processing machine WM0 and are integrated into the component placement device WM3.

[0041] In particular, the plate processing machine WM0 of the embodiment has a component placement device WM3. As described above, in the component placement device WM3, two component placement devices 50, which have a common structure and attach components to the plate 90, are arranged opposite each other on the same base. In addition, each of the two component placement devices 50 has at least one (in Fig. 2 and Fig. 3) screen 60. For the sake of simplicity, the screen 60 located on the first page S1 is referred to as screen 60a and the screen 60 located on the second page S2 as screen 60b.

[0042] Setting section 71 allows the worker to set a valid screen 60y on a display 61. In this description, screen 60, which is at least one of several (two in the Fig. 2 and Fig. 3) Screens 60, 60, and has an operating authorization to operate the WM0 plate processing machine, are designated as valid screen 60y. In addition, screen 60, which is at least one of several (two in the Fig. 2 and Fig. 3) Screens 60, 60, and does not have an operating authorization to operate the WM0 plate processing machine, are designated as invalid screen 60m. In Fig. For example, screen 60a, located on the first page S1, is marked as valid screen 60y and screen 60b, located on the second page S2, is marked as invalid screen 60m.

[0043] Several (two in the Fig. 2 and Fig. 3) Screens 60, 60 and the setting section 71 can take different forms, as long as the worker can set the valid screen 60y on display 61. For example, if the invalid screen 60m prohibits any operation of screen 61 by the worker, the switching of the operating authorization for the control of the plate processing machine WM0 must be done on the valid screen 60y, which may complicate the switching of the operating authorization.

[0044] Therefore, as in Fig. As shown in Figure 4, each of the multiple (two) screens 60 has a normal area 62 and a specific area 63. The normal area 62 is an area on the display 61 and is an area that can be operated by the worker regardless of whether screen 60 is a valid screen 60y. The specific area 63 is an area on the display 61 that differs from the normal area 62 and can be set by the worker on the valid screen 60y. In the form described above, the setting section 71 allows the worker to set the valid screen 60y within the normal area 62. Accordingly, the worker can set the valid screen 60y on the display 61 regardless of whether the screen 60 to be operated is a valid screen 60y.

[0045] Furthermore, specific area 63 is an area that the worker can operate on the valid screen 60y and does not need to be displayed on the invalid screen 60m. Therefore, specific area 63 does not need to be displayed on the invalid screen 60m, but can be displayed on the valid screen 60y. Consequently, it is possible to prevent the worker from mistakenly assuming a problem if they cannot operate specific area 63 on the invalid screen 60m.

[0046] Specific area 63 can also be displayed on the invalid screen 60m to clearly indicate that the worker cannot work. For example, specific area 63 can be displayed differently on the invalid screen 60m than on the valid screen 60y (e.g., by changing the display color, adding a symbol in the form of a circle with a diagonal line, or similar). This approach also prevents the aforementioned misunderstanding.

[0047] The worker can perform various operations on display 61 within a specific area 63 of the valid screen 60y. For example, within a specific area 63, the worker can instruct the plate processing machine WM0 to perform at least one of the following operations: start plate processing, switch to power-saving mode, return from power-saving mode, and stop plate processing. As shown in Fig. As shown in Figure 4, the specific area 63 has a start symbol 63a, an energy-saving mode symbol 63b, and a stop symbol 63c. When the worker activates (touches) the start symbol 63a, the WM0 plate processing machine starts the plate processing.

[0048] When the operator presses (touches) the energy-saving mode symbol 63b, the mode switches from normal mode to energy-saving mode. When the operator presses (touches) the energy-saving mode symbol 63b again, the mode returns from energy-saving mode to normal mode. When the operator presses (touches) the stop symbol 63c, the WM0 plate processing machine stops processing the plates. In this way, the operator can perform various operations on display 61 within a specific area 63 of the valid screen 60y to operate the WM0 plate processing machine.

[0049] As in Fig. As shown in Figure 4, each of the multiple (two) screens 60, 60 can have a display area 64. The display area 64 is an area that the worker cannot operate on screen 61 and in which the plate processing machine WM0 and the like can display various types of information. For example, the display area 64 can show the operating status and production status of the plate processing machine WM0, instructions for the worker, and the like.

[0050] As described above, setting section 71 allows the worker to set a valid screen 60y within the normal range 62. Accordingly, the worker can set a valid screen 60y on display 61, regardless of whether the screen 60 being operated is a valid screen 60y. However, there are cases, for example, where it is desirable to maintain the current setting of the valid monitor 60y depending on the worker's work status.

[0051] Therefore, provision section 71, as in Fig. Figure 4 shows the setting symbol 71a and the retention symbol 71b on display 61. The setting symbol 71a is a symbol for setting the valid monitor 60y. The retention symbol 71b is a symbol for prohibiting the designation of the invalid screen 60m as the valid screen 60y and for retaining the current designation of the valid screen 60y.

[0052] In particular, if the worker activates (touches) the setting symbol 71a on the first screen 60, the first screen 60 is set as valid screen 60y. In this state, if the worker activates (touches) the setting symbol 71a or the retention symbol 71b on the second screen 60, which is different from the first screen 60, the second screen 60 is set as valid screen 60y and the first screen 60 as invalid screen 60m.

[0053] However, if the worker activates (touches) the retention symbol 71b on the first screen 60, the first screen 60 is set as the valid screen 60y, and the setting remains in effect. Therefore, on the second screen 60, which differs from the first screen 60, even if the worker activates (touches) either the setting symbol 71a or the retention symbol 71b, the valid screen 60y setting on the first screen 60 is retained, and the invalid screen 60m setting on the second screen 60 is retained.

[0054] In this state, the first screen 60 relinquishes its status as valid screen 60y when the worker activates (touches) the setting symbol 71a on the first screen 60. If the worker activates (touches) either the setting symbol 71a or the retention symbol 71b on the second screen 60, the second screen 60 is set as valid screen 60y and the first screen 60 is set as invalid screen 60m. Furthermore, the above description of the first screen 60 and the second screen 60 can be similarly applied to a mold in which the first screen 60 and the second screen 60 are reversed.

[0055] As the number of screens 60 increases, it can become more difficult for the worker to identify the position of screen 60 that is set as the valid screen 60y in the WM0 plate processing machine. Therefore, as in Fig. Figure 5 shows that the setting section 71 displays an image simulating the arrangement of multiple (two) screens 60, 60 in the plate processing machine WM0 on the display 61, so that the worker can set the valid screen 60y.

[0056] Fig. Figure 5 shows another display example for normal range 62, where normal range 62 is shown enlarged. This drawing shows that normal range 62 displays an image that represents the arrangement of several (two) screens 60, 60 in the Fig. The component placement device WM3 shown in the 2 is simulated. The one in Fig. The normal area 62 shown in Figure 5, for example, denotes the normal area 62 of the screen 60a located on the first page S1. A symbol (rectangle) of the screen 60, represented in the drawing by a solid line, denotes the screen 60a located on the first page S1. A symbol (rectangle) of the screen 60, represented in the drawing by a dashed line, denotes the screen 60b located on the second page S2.

[0057] Since the drawing shows the normal area 62 of screen 60a, which is located on the first side S1, the symbol (rectangle) of screen 60a located on the first side S1 is highlighted in comparison to the symbol (rectangle) of screen 60b located on the second side S2. Furthermore, the setting symbol 71a and the retention symbol 71b are displayed on the symbol (rectangle) of screen 60a located on the first side S1, and the operator can touch (activate) the setting symbol 71a or the retention symbol 71b. Accordingly, the operator can easily identify the position of screen 60 (screen 60a in the example above) that is to be set as the valid screen 60y in the component placement device WM3. The above description of screen 60a can be applied similarly to screen 60b.

[0058] As described above, setting section 71 allows the operator to set the valid screen 60y on display 61, thus eliminating the need for the mechanical switch to change the operator authorization to operate the WM0 plate processing machine. Furthermore, within a specific area 63, the operator can instruct the WM0 plate processing machine to perform a predetermined operation, and the mechanical switch for that predetermined operation can be omitted. However, due to standards, some mechanical switches cannot be omitted when operating the WM0 plate processing machine.

[0059] Therefore, the WM0 plate processing machine, as described in Fig. Figure 4 shows a mechanical switch 46 that allows the operator to perform a predetermined operation on the plate processing machine WM0 regardless of whether or not they have the necessary operating authorization. The mechanical switch 46 can take various forms, as long as it can mechanically switch an instruction to the plate processing machine WM0. For example, the mechanical switch 46 can include an emergency stop switch 46a for emergency stopping the powered plate processing machine WM0.

[0060] The operator can stop the driven plate processing machine WM0 in an emergency by pressing the emergency stop switch 46a. When the operator presses the emergency stop switch 46a, the plate processing machine WM0 immediately stops the plate processing in progress. If the operator activates (touches) the stop symbol 63c within a specific area 63, the plate processing machine WM0 stops plate processing. In this case, the plate processing machine WM0 stops plate processing after a predetermined pick-up and placement cycle has been completed.

[0061] As in Fig. As shown in Figure 4, the mechanical switch 46 can have at least one mechanical switch 46b in addition to the emergency stop switch 46a. The mechanical switch 46b can be used for any operation of the plate processing machine WM0. For example, if the mechanical switch 46b is actuated by the operator, the plate processing machine WM0 can start, interrupt, or stop any plate processing operation.

[0062] When the worker performs a predetermined task on the plate processing machine WM0, it is very likely that he operates the plate processing machine WM0 via screen 60, which is located on the side where the predetermined task is performed. Therefore, when the worker performs the predetermined task on the plate processing machine WM0, the setting section 71 can define as the valid screen 60y the corresponding screen 60t, which is located on the side where the predetermined task is performed, among several (two) screens 60, 60.

[0063] The predetermined work is not limited. For example, the predetermined work includes at least one of the following: attaching and removing a component feeder 20, which feeds the component into a component placement device 50, which places the component onto a circuit board 90, and opening and closing a protective cover 44, which protects the worker. As for example in Fig. As shown in Figure 2, in a case where the component feed device 20a located on the first side S1 is attached or removed, the screen 60a located on the first side S1 is highly likely to be used. Likewise, in a case where the protective cover 44a located on the first side S1 is opened or closed, the screen 60a located on the first side S1 is highly likely to be used.

[0064] In any case, the corresponding screen 60t is the screen 60a located on the first side S1. Therefore, specification section 71 designates the screen 60a located on the first side S1, which is the corresponding screen 60t, as the valid screen 60y. Similarly, if the component feeder 20b located on the second side S2 is attached or removed, specification section 71 designates the screen 60b located on the second side S2, which is the corresponding screen 60t, as the valid screen 60y. If the protective cover 44b located on the second side S2 is opened or closed, specification section 71 designates the screen 60b located on the second side S2, which corresponds to screen 60t, as the valid screen 60y.

[0065] The component placement device WM3 has a sensor that detects the attachment and removal of the component feeder 20 as well as the opening and closing of the protective cover 44. The setting section 71 can detect the attachment and removal of the component feeder 20 as well as the opening and closing of the protective cover 44 based on a detection result from the sensor. In this way, if the worker is performing the predetermined task on the plate processing machine WM0, the setting section 71 can automatically set the valid monitor 60y by simulating the worker's setting of the valid monitor 60y. 1-3-2. Identification section 72

[0066] As in Fig. As shown in Figure 1, a production plant of one embodiment has two production lines WL0, including a first production line WL1 and a second production line WL2. For example, a worker responsible for the first production line WL1 and a worker responsible for the second production line WL2 can be distinguished from one another. In this case, it is not desirable for the worker responsible for the first production line WL1 to operate the panel processing machine WM0 of the second production line WL2. Likewise, it is not desirable for the worker responsible for the second production line WL2 to operate the panel processing machine WM0 of the first production line WL1.

[0067] Therefore, the identification section 72 identifies the worker. The identification section 72 can take various forms, as long as it can identify the worker. For example, the identification section 72 can read an identification card carried by the worker using a reader and capture identification information that can be used to identify the worker. The identification section 72 can also identify the worker through biometric authentication, such as fingerprint or facial authentication.

[0068] Setting section 71 allows the setting of a valid screen 60y in a case where the worker identified by identification section 72 is a predetermined worker who can set a valid screen 60y, and prohibits the setting of a valid screen 60y in a case where the worker identified by identification section 72 is not the predetermined worker. Accordingly, setting section 71 can allow the predetermined worker to set a valid screen 60y and prohibit a worker who is not the predetermined worker from setting a valid screen 60y. 2. Other forms

[0069] As in Fig.As shown in Figure 2, the WM0 plate processing machine of the embodiment has a component placement device WM3 in which two component placement devices 50 with a common structure, which secure the components to the printed circuit board 90, are arranged opposite each other on the same base. In addition, each of the two component placement devices 50 has at least one (in the drawing, one) screen 60.

[0070] However, the circuit board processing machine WM0 and the multiple screens 60 are not limited to the form described above. For example, the component placement device WM3 can have at least one component placement device 50 that attaches a component to the circuit board 90. Furthermore, a component placement device WM3 can be equipped with at least one screen 60. The production line WL0 can have several component placement devices WM3 with a common structure and multiple screens 60.

[0071] Several component placement devices WM3 can be arranged along the conveying direction (X-direction) of the printed circuit board 90. In this case, the screen 60 provided in the first component placement device WM3 can be used to operate the second component placement device WM3. The screen 60 provided in the first component placement device WM3 corresponds to the valid screen 60y, and the screen 60 provided in the second component placement device WM3 corresponds to the invalid screen 60m. The board processing machine WM0 is not limited to the component placement device WM3. The board processing machine WM0 can be any of the various board processing machines WM0 described above, such as the printing machine WM1. 3. Example of the effects of embodiments
