[Modes for carrying out the invention]
[0012] Next, the forms for implementing this disclosure will be described with reference to the drawings.
[0013] Figure 1 is an external perspective view of the PCB production line 1. Figure 2 is an external perspective view of the component mounting machine. Figure 3 is a schematic configuration diagram of the component mounting machine 10. Figure 4 is a block diagram showing the electrical connection relationships of each component mounting machine 10 in the PCB production line 1. In Figures 1 and 2, the left-right direction is the X-axis direction, the front-back direction is the Y-axis direction, and the up-down direction is the Z-axis direction.
[0014] The substrate production line 1 of this embodiment produces a substrate S on which components are mounted. As shown in FIG. 1, as the substrate production machines (modules) constituting the substrate production line 1, there are a printer 2, a printing inspection machine 3, a plurality of component mounters 10 (10A, 10B, 10C, 10D), a mounting inspection machine 4, a reflow furnace 5, and the like. These are arranged along the conveyance direction of the substrate S. The printer 2 prints solder on the substrate S by pressing solder into the pattern holes formed in the screen mask. The printing inspection machine 3 inspects the state of the solder printed by the printer 2. The mounting inspection machine 4 inspects the mounting state of the components mounted on the substrate S by the component mounters 10 (10A, 10B, 10C, 10D). The reflow furnace 5 heats the substrate S on which components are arranged on the solder to melt the solder, and then cools it to electrically connect and fix each component on the substrate S.
[0015] As shown in FIGS. 2 and 3, each component mounter 10 (10A, 10B, 10C, 10D) includes a mounter main body 20 including a substrate conveyance device 21, a head 22, and a head movement device 23, a feeder 30 that supplies components to the mounter main body 20, and an operation panel 40 (40A, 40B, 40C, 40D) having a touch panel type screen. Further, as shown in FIG. 4, each component mounter 10 includes a module control device 50 (50A, 50B,..., 50D) that controls the mounter main body 20, and a screen control device 60 (60A, 60B,..., 60D) that controls the screen of the operation panel 40.
[0016] The substrate conveyance device 21 is a belt conveyor device that conveys the substrate S left and right (in the X-axis direction) by a conveyor belt.
[0017] The head 22 includes a holder to which a suction nozzle (collection member) is detachably attached, and a lifting device that moves the holder up and down (in the Z-axis direction). Negative pressure from a negative pressure source is supplied to the suction nozzle via a solenoid valve, and the suction nozzle is able to pick up (collect) parts by negative pressure. The head moving device 23 moves the head 22 forward, backward, left and right (in the XY-axis direction). This head moving device 23 has a Y-axis slider that moves forward and backward (in the Y-axis direction) driven by a Y-axis motor, and an X-axis slider that moves left and right (in the X-axis direction) relative to the Y-axis slider driven by an X-axis motor. The head 22 is attached to the X-axis slider and moves forward, backward, left and right (in the XY-axis direction) driven by the X-axis motor and Y-axis motor. In this embodiment, as shown in Figures 2 and 3, the component mounting machine 10 has two heads 22 that can move independently of each other by their respective head moving devices 23.
[0018] The component mounting machine 10 also includes a mark camera 25, a parts camera 26, and a nozzle stocker 27. The mark camera 25 captures a reference mark placed on the substrate S from above in order to detect the position of the substrate S. The parts camera 26 captures a part picked up by the suction nozzle from below in order to detect suction errors or misalignment. The nozzle stocker 27 stores multiple types of suction nozzles that can be attached to the holder of the head 22.
[0019] The module control devices 50 (50A, 50B, ..., 50D) are configured as microprocessors centered around a CPU, and in addition to the CPU, they include ROM, RAM, storage, input / output ports, and communication ports. The module control devices 50 receive detection signals from position sensors to detect the positions of the head 22 in the X and Y axes, and also receive image signals captured by the parts camera 26 and the mark camera 25. Furthermore, the module control devices 50 output control signals to the feeder 30, the substrate transport device 21, the head moving device 23, the parts camera 26, the mark camera 25, and other components.
[0020] As shown in Figure 4, the module control device 50 has the module device OS 51 installed in its storage, and the module application (hereinafter referred to as module app) 52 is installed in the module device OS 51. The CPU of the module control device 50 controls the mounting machine body 20 by executing the module app 52 under the management of the module device OS 51. The control of the mounting machine body 20 mainly includes sampling control and mounting control. Sampling control is performed by controlling the head moving device 23 so that the head 22 moves above the component supply position of the feeder 30, and then controlling the head 22 (lifting device) so that the suction nozzle of the head 22 descends to pick up the component at the component supply position. Mounting control is performed by controlling the head moving device 23 so that the head 22 moves above the designated mounting position on the substrate S, and then controlling the head 22 (lifting device) so that the suction nozzle of the head 22 descends to mount the component at the mounting position.
[0021] The screen control devices 60 (60A, 60B, ..., 60D) are configured as microprocessors centered around a CPU, and in addition to the CPU, they include ROM, RAM, storage, input / output ports, and communication ports. The screen control devices 60 are connected to the module control devices 50 via communication ports and, in cooperation with the module control devices 50, display the operating status of the corresponding component mounting machine 10 and other information on the corresponding operation panels 40 (40A, 40B, 40C, 40D).
[0022] As shown in Figure 4, the screen control device OS 61 is installed in the storage of the screen control device 60, and the screen control application (hereinafter referred to as the screen control app) 62 is installed in the screen control device OS 61. The CPU of the screen control device 60 controls the display of the screen by executing the screen control app 62 under the management of the screen control device OS 61. The displayed content includes status information indicating the operating status of the component mounting machine 10, such as "in production," "in setup change," or "anomaly occurred."
[0023] The module control device 50 and the screen control device 60 are each provided with separate circuit breakers (main breaker 55 and sub-breaker 65). The main breaker 55 switches the supply and interruption of power to the module control device 50, while the sub-breaker 65 switches the supply and interruption of power to the screen control device 60 independently of the module control device 50. The module control device 50 is equipped with a power storage device, and when the main breaker 55 is turned off, it can operate for a certain period of time using the power of the power storage device. Similarly, the screen control device 60 is equipped with a power storage device, and when the sub-breaker 65 is turned off, it can operate for a certain period of time using the power of the power storage device.
[0024] Furthermore, the screen control device 60A of component mounting machine 10A, one of the multiple component mounting machines 10 (10A, 10B, 10C, 10D), and the module control devices 50 of each component mounting machine 10 (10A, 10B, 10C, 10D) are connected via FTP (File Transfer Protocol) for communication. In addition, as shown in Figure 4, the screen control device OS 61 of the screen control device 60A has a line control unit (hereinafter referred to as LCU) 63 installed for managing the board production line 1, in addition to the screen control application 62. The CPU of the screen control device 60A executes the LCU 63 under the management of the screen control device OS 61, and communicates with each component mounting machine 10 to instruct them to mount components according to the production schedule stored in storage. The production schedule specifies which components on which board S are mounted in what order at each component mounting machine 10, and how many boards S with such mounting are to be manufactured. In addition to managing each component mounting machine 10, the LCU63 also controls the aforementioned printing machine 2, printing inspection machine 3, mounting inspection machine 4, and reflow oven 5.
[0025] Next, the operation of the circuit board production line 1 configured in this way will be described. In particular, the operation when the main breaker 55 is turned off and then turned on, and the operation when the sub-breaker 65 is turned off and then turned on will be described. Figure 5 is an explanatory diagram showing the operation flow of the screen control application 62, the screen control device OS 61, the module device OS 51, and the module application 52 when the main breaker 55 is turned off. Figure 6 is an explanatory diagram showing the operation flow of the screen control application 62, the screen control device OS 61, the module device OS 51, and the module application 52 when the main breaker 55 is turned on.
[0026] As shown in Figure 5, when the module device OS51 detects that the main breaker 55 has been turned off by an operator (step S100) (step S110), it notifies the screen control device OS61 that the main breaker 55 has been turned off (step S120). As described above, even when the main breaker 55 is turned off, the module control device 50 continues to operate for a certain period of time using power from the energy storage device. During this time, the module device OS51 notifies the screen control device OS61 that the main breaker 55 has been turned off. Subsequently, the module device OS51 stops due to the cessation of power supply caused by the turning off of the main breaker 55 (step S130). The module application 52 also stops due to the cessation of power supply caused by the turning off of the main breaker 55 (step S140). Since the sub-breaker 65 remains on, power supply to the screen control device 60 is maintained.
[0027] The screen control device OS61 receives notification from the module device OS51 that the main breaker 55 has been turned off (step S150) and instructs the screen control application 62 to terminate the application (step S160). When the screen control application 62 is instructed to terminate the application, it instructs the screen control device OS61 to restart (step S170) and then terminates the application (step S180). When the screen control device OS61 is instructed to restart by the screen control application 62, it restarts itself (step S190).
[0028] As shown in Figure 6, when the main breaker 55 is turned on again by the operator (step S200) and the module device OS 51 starts up with power supply (step S210), it notifies the screen control device OS 61 that it has finished starting up (step S220) and starts the module application 52 (step S230). When the screen control device OS 61 receives notification that the module device OS 51 has finished starting up (step S240), it starts the screen control application 62 (step S250). When the screen control application 62 starts up, it reports to the module application 52 that it has finished starting up (step S260). When the module application 52 receives the report from the screen control application 62 that it has finished starting up (step S270), it reports to the screen control application 62 that it has received the report (step S280) and establishes communication with the screen control application 62 (step S290). Meanwhile, the screen control application 62 receives a report from the module application 52 indicating that reception is complete (step S300) and establishes communication with the module application 52 (step S310). This enables communication between the module application 52 and the screen control application 62, and the screen control application 62 receives various information from the module application 52 via communication and displays the received information on the operation panel 40.
[0029] Figure 7 is an explanatory diagram showing the operation flow of the screen control application 62, screen control device OS 61, module device OS 51, and module application 52 when the sub-breaker 65 is turned off. Figure 8 is an explanatory diagram showing the operation flow of the screen control application 62, screen control device OS 61, module device OS 51, and module application 52 when the sub-breaker 65 is turned on again.
[0030] As shown in Figure 7, when the sub-breaker 65 is turned off by the operator (step S400), the screen control device OS 61 detects that the sub-breaker 65 has been turned off (step S410) and notifies the module device OS 51 that the sub-breaker 65 has been turned off (step S420). As described above, even when the sub-breaker 65 is turned off, the screen control device 60 continues to operate for a certain period of time using power from the energy storage device. During this time, the screen control device OS 61 notifies the module device OS 51 that the sub-breaker 65 has been turned off. Subsequently, the screen control device OS 61 stops due to the cessation of power supply caused by the sub-breaker 65 being turned off (step S430). The screen control application 62 also stops due to the cessation of power supply caused by the sub-breaker 65 being turned off (step S440). Since the main breaker 55 remains on, power supply to the module control device 50 is maintained.
[0031] When the module device OS51 receives notification from the screen control device OS61 that the sub-breaker 65 has been turned off (step S450), it instructs the module application 52 to terminate the application (step S460) and restarts itself (step S470). When the module application 52 is instructed to terminate the application, it terminates itself.
[0032] As shown in Figure 8, when the sub-breaker 65 is turned on by the operator (step S500) and the power is supplied, the screen control device OS 61 starts up (step S510), notifies the module device OS 51 that it has finished starting up (step S520), and starts the screen control application 62 (step S530). When the module device OS 51 receives notification that the screen control device OS 61 has finished starting up (step S540), it starts the module application 52 (step S550). Then, when the module application 52 starts up, it notifies the screen control device OS 61 that it has finished starting up (step S560). When the screen control device OS 61 receives notification that the module application 52 has finished starting up (step S570), it reports to the screen control application 62 that the module application 52 has finished starting up (step S580). The screen control application 62 receives a report from the module application 52 that it has finished starting up (step S590) and reports to the module application 52 that it has finished starting up itself (step S600). When the module application 52 receives the report from the screen control application 62 that it has finished starting up (step S610), it reports to the screen control application 62 that it has finished receiving the report (step S620) and establishes communication with the screen control application 62 (step S630). Meanwhile, the screen control application 62 receives a report from the module application 52 that it has finished receiving the report (step S640) and establishes communication with the module application 52 (step S650). As a result, communication between the module application 52 and the screen control application 62 becomes possible, and the module application 52 sends various information to the screen control application 62 via communication, causing the screen control application 62 to display various information on the operation panel 40.
[0033] Here, the correspondence between the components of this embodiment and the components of the present invention will be clarified. The component mounting machine 10 (10A, 10B, 10C, 10D) of this embodiment corresponds to the substrate production machine of this disclosure, the module control devices 50 (50A, 50B, ..., 50D) correspond to the first control device, the screen control devices 60 (60A, 60B, ..., 60D) correspond to the second control device, the main breaker 55 corresponds to the first breaker, and the sub-breaker 65 corresponds to the second breaker. Furthermore, the module application 52 corresponds to the first control application, and the screen control application 62 corresponds to the second control application.
[0034] It goes without saying that the present invention is not limited in any way to the embodiments described above, and can be implemented in various forms as long as they fall within the technical scope of the present invention.
[0035] For example, in the embodiment described above, the component mounting machine 10A is equipped with an LCU 63 in the screen control device 60, but the LCU 63 may be provided in a separate control device.
[0036] Furthermore, in the above-described embodiment, the screen control device 60 is equipped with a screen control application 62 that controls the display of the operation panel 40 in cooperation with the module application 52 of the module control device 50. However, it can be applied to any application as long as it is controlled in cooperation with the module application 52 of the module control device 50.
[0037] Furthermore, in the above-described embodiment, a substrate production machine equipped with a first control device and a second control device was described in relation to a component mounting machine 10 equipped with a module control device 50 and a screen control device 60. However, it is not limited to this, and can be applied to any substrate production machine, such as a printing press 2, a printing inspection machine 3, a mounting inspection machine 4, or a reflow oven 5, as long as it is equipped with a first control device involved in substrate production and a second control device that performs other controls (for example, a control device that controls the operation panel mounted on the substrate production machine).
[0038] As explained above, separate circuit breakers are installed for the first control unit, which executes the first control related to the production of circuit boards, and the second control unit, which executes a second control that is different from the first control. This makes it possible to operate the second control unit even when the power to the first control unit is turned off in the circuit board production machine.
[0039] In the substrate production machine of this disclosure, the second control may be one of a plurality of substrate production machines constituting a substrate production line, and the second control may include management control for managing the substrate production line. This would eliminate the need to provide a separate control device for managing the substrate production line, thus simplifying the system. In this case, the system may be equipped with a display device that displays various information about the substrate production machine, and the second control may include display control for the display device.
[0040] Furthermore, in the substrate production machine of this disclosure, the operating system of the first control unit has a first control application installed, and the operating system of the second control unit has a second control application installed. The operating system of the first control unit notifies the second control unit that the first breaker has been turned off before stopping when the first breaker is turned off, and when the first breaker is turned on during stopping and the operating system starts up, it notifies the second control unit that it has started up and starts the first control application to establish communication between the first control application and the second control application. The operating system of the second control unit restarts when it receives notification from the first control unit that the first breaker has been turned off, and when it receives notification from the first control unit that it has started up, it starts the second control application to establish communication between the second control application and the first control application. In this way, even if the first breaker is turned on again after being turned off, the establishment of communication between the first control application and the second control application can be performed smoothly.
[0041] Furthermore, in the substrate production machine of this disclosure, the operating system of the first control unit has a first control application installed, and the operating system of the second control unit has a second control application installed. The operating system of the second control unit notifies the first control unit that the second breaker has been turned off before stopping when the second breaker is turned off, and when the second breaker is turned on during stopping and the operating system starts up, it notifies the first control unit that it has started up and starts the second control application to establish communication between the second control application and the first control application. The operating system of the first control unit may restart its operating system when it receives notification from the second control unit that the second breaker has been turned off, and when it receives notification from the second control unit that it has started up, it starts the first control application to establish communication between the first control application and the second control application. In this way, even if the second breaker is turned on again after being turned off, the establishment of communication between the first control application and the second control application can be performed smoothly.
[0042] Furthermore, this disclosure is not limited to the form of a circuit board production machine, but can also be in the form of a circuit board production line.
[0043] This specification also discloses technical concepts in which "the substrate production machine described in claim 2" was changed to "the substrate production machine described in claim 1 or 2" in claim 3 of the original application, and technical concepts in which "the substrate production machine described in any one of claims 1 to 3" was changed to "the substrate production machine described in any one of claims 1 to 4" in claim 5 of the original application.
