Description of the embodiments

[0011] Next, an embodiment of the present disclosure will be described with reference to the drawings.

[0012] Fig. 1 is an external perspective view of a circuit board production line 1. Fig. 2 is an external perspective view of a component picker. Fig. 3 is a schematic configuration diagram of the component mounter 10. Fig. 4 is a block diagram illustrating an electrical connection relationship of each component mounter 10 of a circuit board production line 1. In Fig. 1 and Fig. 2, a left-right direction represents an X-axis direction, a front-back direction represents a Y-axis direction, and an up-down direction represents a Z-axis direction.

[0013] The circuit board production line 1 of the present embodiment is used to manufacture a circuit board S on which components are mounted, and a circuit board production machine (module) constituting the circuit board production line 1 includes a printing machine 2, a printing inspection machine 3, a plurality of component mounters 10 (10A, 10B, 10C, and 10D), an assembly inspection device 4, a reflow oven 5, and the like, as shown in Fig. 1. These are arranged along a conveying direction of the circuit board S. The printing machine 2 prints solder on the circuit board S by forcing the solder into pattern holes formed in a screen mask. The printing inspection machine 3 inspects a condition of the solder printed by the printing machine 2. The mounting inspection device 4 inspects the mounting condition of the components mounted on the circuit board S by the component mounter 10 (10A, 10B, 10C, and 10D). The reflow oven 5 melts the solder by heating the circuit board S on which the component is mounted on the solder and then cools the solder, thereby electrically connecting the component to the circuit board S to be fixed to the circuit board S.

[0014] As in the Fig. 2 and Fig. As shown in Figure 3, each component mounter 10 (10A, 10B, 10C, and 10D) includes a mounter main body 20 having a board conveying device 21, a head 22 and a head moving device 23, a feeder device 30 for feeding components to the mounter main body 20, and an operation panel 40 (40A, 40B, 40C, and 40D) having a touchscreen type display. Further, as shown in Fig. 4, each component mounter 10 includes a module control device 50 (50A, 50B, ..., 50D) for controlling the mounter main body 20 and a screen control device 60 (60A, 60B, ..., and 60D) for controlling the screen of the operation panel 40.

[0015] The board conveying device 21 is a belt conveying device that conveys the board S to the left and right (X-axis direction) with a conveyor belt.

[0016] The head 22 includes a mount to which a suction nozzle (collecting element) is detachably attached, and a lifting and lowering device that raises and lowers the mount (in the Z-axis direction). Negative pressure from a vacuum source is applied to the suction nozzle via a solenoid valve, and the suction nozzle can pick up (collect) components using the negative pressure. The head moving device 23 moves the head 22 in the front-back and left-right directions (XY-axis directions). The head moving device 23 includes a Y-axis slider that moves in the front-to-back direction (in the Y-axis direction) by being driven by a Y-axis motor, and an X-axis slider that moves in the left-to-right direction (in the X-axis direction) with respect to the Y-axis slider by being driven by an X-axis motor.The head 22 is attached to the X-axis slider and moves in the front-back and left-right directions (XY-axis directions) by being driven by the X-axis motor and the Y-axis motor. In the present embodiment, as shown in FIGS. Fig. 2 and Fig. 3, the component mounter 10 has two heads 22 that can move independently of each other in each head moving device 23.

[0017] In addition, the component mounter 10 also includes a marking camera 25, a component camera 26, and a nozzle magazine 27. The marking camera 25 captures an image of a reference mark applied to the board S from above to detect the position of the board S. The component camera 26 captures an image of a component picked up by the suction nozzle from below to detect a picking error or a picking deviation. The nozzle magazine 27 stores several types of suction nozzles that can be attached to the holder of the head 22.

[0018] The module control device 50 (50A, 50B, ..., and 50D) is configured as a microprocessor centrally located on the CPU and includes, in addition to the CPU, a ROM, a RAM, a memory, an input / output port, a communication port, and the like. The module control device 50 inputs a detection signal from a position sensor for detecting each position of the head 22 in the X-axis direction and the Y-axis direction, and inputs a signal of an image captured by the component camera 26 or the marking camera 25. The module control device 50 outputs control signals to the feeder 30, the board conveying device 21, the head moving device 23, the component camera 26, the marking camera 25, and the like.

[0019] As in Fig. As shown in Fig. 4, a module device OS 51 is installed in the memory of the module control device 50, and a module application (hereinafter referred to as a module application) 52 is installed in the module device OS 51. The CPU of the module control device 50 controls the mounter main body 20 by executing the module application 52 under the management of the module device OS 51. The control of the mounter main body 20 mainly includes batch control and mounting control. The batch control is performed by controlling the head moving device 23 so that the head 22 moves over a component feeding position of the feeding device 30, and then controlling the head 22 (lifting and lowering device) so that the suction nozzle of the head 22 is lowered and the component is gripped at the component feeding position.The mounting control is carried out by controlling the head moving device 23 so that the head 22 moves over the intended mounting position of the board S, and then by controlling the head 22 (lifting and lowering device) so that the suction nozzle of the head 22 is lowered and the component is mounted at the mounting position.

[0020] The screen control device 60 (60A, 60B, ..., and 60D) is configured as a microprocessor centrally located on the CPU and includes, in addition to the CPU, a ROM, a RAM, a memory, an input / output port, a communication port, and the like. The screen control device 60 communicates with the module control device 50 via the communication port and, in cooperation with the module control device 50, displays the operating status of the respective component mounter 10 and other information on the corresponding control panel 40 (40A, 40B, 40C, and 40D).

[0021] As in Fig. 4, a screen control device OS 61 is installed in the memory of the screen control device 60, and a screen control application (hereinafter referred to as a screen control application) 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 application 62 under the management of the screen control device OS 61. The display content includes, for example, status information indicating the operating status of a component mounter 10, such as during production or during setup change and during the occurrence of an abnormality.

[0022] A circuit breaker (main circuit breaker 55, sub-circuit breaker 65) is provided separately in each of the module control device 50 and the display control device 60. The main circuit breaker 55 switches between supplying power to the module control device 50 and interrupting that power supply, and the sub-circuit breaker 65 switches between supplying power to the display control device 60 and interrupting that power supply, independently of the module control device 50. The module control device 50 includes a power storage device, and when the main circuit breaker 55 is turned off, the module control device 50 can operate for a certain period of time using the electrical energy from the power storage device.Similarly, the screen control device 60 includes an energy storage device, and when the sub-breaker 65 is turned off, the screen control device 60 can be operated for a certain period of time using the electrical energy of the energy storage device.

[0023] Furthermore, the screen control device 60A of the component mounter 10A, which is one of a plurality of component mounters 10 (10A, 10B, 10C, and 10D), and the module control device 50 of each of the component mounters 10 (10A, 10B, 10C, and 10D) are communicatively connected via a file transfer protocol (FTP). In addition to the screen control application 62, a line control unit (hereinafter referred to as LCU) 63 for managing the board production line 1 is installed in the screen control device OS 61 of the screen control device 60A, as shown in FIG. Fig. 4. The CPU of the screen control device 60A executes the LCU 63 under the management of the screen control device OS 61 and instructs each component mounter 10 to mount the component through communication according to the production plan stored in the memory. The production plan specifies which components are to be mounted on which boards S by each component mounter 10, in what order, and how many boards S thus mounted are to be produced. In addition to each component mounter 10, the LCU 63 also manages the printing press 2, the printing test machine 3, the assembly tester 4, and the reflow oven 5 described above.

[0024] Next, the operation of the circuit board production line 1 configured as described above will be described. Specifically, an operation in which the main breaker 55 is turned off and then turned on again and an operation in which the sub-breaker 65 is turned off and then turned on again will be described. Fig. 5 is a diagram illustrating the flow of each operation 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. Fig. 6 is a diagram illustrating the flow of each operation 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 again.

[0025] As in Fig. 5, when the main breaker 55 is turned off by a worker (step S100) and it is detected that the main breaker 55 is turned off (step S110), the module device OS 51 notifies the display control device OS 61 that the main breaker 55 is turned off (step S120). As described above, since the module control device 50 is operated for a certain period of time with the electric power from the energy storage device, the module device OS 51 notifies the display control device OS 61 that the main breaker 55 is turned off during the certain period of time, even if the main breaker 55 is turned off. Thereafter, the module device OS 51 stops when the power supply is turned off by turning off the main breaker 55 (step S130).The module application 52 also stops when the power supply is turned off by turning off the main breaker 55 (step S140). Since the sub-breaker 65 remains on, the power supply to the display control device 60 is maintained.

[0026] The screen control device OS 61 receives a notification from the module device OS 51 indicating that the main breaker 55 is being turned off (step S150) and instructs the screen control application 62 to terminate the application (step S160). If the end of the application is instructed, the screen control application 62 instructs the screen control device OS 61 to restart (step S170) and then terminates the application (step S180). If the restart is instructed by the screen control application 62, the screen control device OS 61 restarts itself (step S190).

[0027] As in Fig. As shown in Figure 6, when the main breaker 55 is turned on again by the worker (step S200) and the module device OS 51 is started by the power supply (step S210), the module device OS 51 notifies the screen control device OS 61 that the startup of the module device OS 51 is complete (step S220) and starts the module application 52 (step S230). After receiving the notification of the completion of the startup of the module device OS 51 (step S240), the screen control device OS 61 starts the screen control application 62 (step S250). When the screen control application 62 starts, the screen control application 62 notifies the module application 52 of the completion of the startup of the screen control application 62 (step S260).After receiving the startup completion report from the screen control application 62 (step S270), the module application 52 notifies the reception completion to the screen control application 62 (step S280) and establishes communication with the screen control application 62 (step S290). Meanwhile, the screen control application 62 receives the reception completion report from the module application 52 (step S300) and establishes communication with the module application 52 (step S310). Accordingly, communication between the module application 52 and the screen control application 62 becomes possible, and the screen control application 62 receives various information from the module application 52 through the communication and displays the received various information on the operation panel 40.

[0028] Fig. 7 is a diagram illustrating the flow of each operation of the screen control application 62, the screen control device OS 61, the module device OS 51, and the module application 52 when the sub-breaker 65 is turned off. Fig. 8 is a diagram illustrating the flow of each operation of the screen control application 62, the screen control device OS 61, the module device OS 51, and the module application 52 when the sub-breaker 65 is turned on again.

[0029] As in Fig. As shown in Figure 7, when the sub-breaker 65 is turned off by the worker (step S400) and it is detected that the sub-breaker 65 is turned off (step S410), the display control device OS61 notifies the module device OS51 that the sub-breaker 65 is turned off (step S420). As described above, since the display control device 60 is powered by the electric power from the power storage device for a certain period of time, the display control device OS61 notifies the module device OS51 that the sub-breaker 65 is turned off during the certain period of time, even if the sub-breaker 65 is turned off. Thereafter, the display control device OS61 stops when the power supply is turned off by turning off the sub-breaker 65 (step S430).The screen control application 62 also stops when the power is turned off by turning off the sub-circuit breaker 65 (step S440). Since the main circuit breaker 55 remains on, the power supply to the module control device 50 is maintained.

[0030] When the module device OS 51 receives a notification from the screen control device OS 61 indicating that the sub-breaker 65 is being turned off (step S450), the module device OS 51 instructs the module application 52 to terminate the application (step S460) and restarts itself (step S470). If the application termination is instructed, the module application 52 terminates the module application 52.

[0031] As in Fig.As shown in Figure 8, when the sub-breaker 65 is turned on again by the worker (step S500) and the screen control device OS61 is started by the power supply (step S510), the screen control device OS61 notifies the module device OS51 that the startup of the screen control device OS61 is completed (step S520) and starts the screen control application 62 (step S530). When the module device OS51 receives the notification of the completion of the startup of the screen control device OS61 (step S540), the module device OS51 starts the module application 52 (step S550). When the module application 52 is started, the module application 52 notifies the screen control device OS61 that the startup of the module application 52 is completed (step S560).After receiving the startup completion notification from the module application 52 (step S570), the screen control device OS 61 reports the completion of the startup of the module application 52 to the screen control application 62 (step S580). The screen control application 62 receives the startup completion report of the module application 52 (step S590) and reports the completion of the startup of the screen control application 62 to the module application 52 (step S600). After receiving the startup completion report of the screen control application 62 (step S610), the module application 52 reports the completion of reception to the screen control application 62 (step S620) and establishes communication with the screen control application 62 (step S630).Meanwhile, the screen control application 62 receives the reception completion report from the module application 52 (step S640) and establishes communication with the module application 52 (step S650). Accordingly, 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 through the communication, causing the screen control application 62 to display various information on the control panel 40.

[0032] Here, a correspondence relationship between the elements of the present embodiment and the elements of the present invention is clarified. The component mounter 10 (10A, 10B, 10C, and 10D) of the present embodiment corresponds to a circuit board production machine according to the present disclosure, the module control device 50 (50A, 50B, ..., and 50D) corresponds to a first control device, the screen control device 60 (60A, 60B, ..., and 60D) corresponds to a second control device, the main breaker 55 corresponds to a first breaker, and the sub-breaker 65 corresponds to a second breaker. The module application 52 corresponds to a first control application, and the screen control application 62 corresponds to a second control application.

[0033] The present invention is in no way limited to the above embodiment, and it goes without saying that the present invention can be embodied in various aspects without departing from the technical scope of the present invention.

[0034] For example, in the above-described embodiment, the component mounter 10A is equipped with the LCU 63 in the screen control device 60, but the LCU 63 may also be provided in a separate control device.

[0035] In the above-described embodiment, the screen control device 60 includes the screen control application 62, which cooperates with the module application 52 of the module control device 50 to control the display of the control panel 40. However, any application may be used as long as it cooperates with the module application 52 of the module control device 50 to perform control.

[0036] Furthermore, in the above-described embodiment, the board production machine including the first control device and the second control device is applied to the component mounter 10 including the module control device 50 and the screen control device 60. However, the present invention is not limited thereto and can be applied to any board production machine as long as it includes, for example, a first control device related to the production of a board, such as a printing machine 2, a printing inspection machine 3, an assembly inspection device 4, and a reflow oven 5, and a second control device (for example, a control device that controls an operation panel attached to the board production machine) that performs other control.

[0037] As described above, different breakers are installed on the first control device, which executes the first control related to the production of the circuit board, and on the second control device, which executes the second control different from the first control. Accordingly, in the circuit board production machine, it is possible to operate the second control device even when the power supply of the first control device is turned off.

[0038] The blank production machine according to the present disclosure may be one of the plurality of blank production machines constituting the blank production line, and the second controller may include a management controller for managing the blank production line.

In this case, the display device may be provided for displaying various information related to the blank production machine, and the second controller may include a display controller for the display device.

[0039] In addition, in the circuit board production machine according to the present disclosure, the first control application may be installed in an operating system of the first control device, the second control application may be installed in an operating system of the second control device, the operating system of the first control device may notify the second control device that the first breaker is turned off before stopping when the first breaker is turned off, and when the first breaker is turned on and the operating system is started during stopping, notify the second control device of the start of the operating system, and the first control application may be started to establish communication between the first control application and the second control application,When the operating system of the second control device receives a notification from the first control device that the first breaker is turned off, the operating system can be restarted. When the operating system receives a notification of the start from the first control device, the second control application can be started to establish communication between the second control application and the first control application. In this way, even if the first breaker is turned off and then turned on again, it is possible to smoothly establish communication between the first control application and the second control application.

[0040] Furthermore, in the circuit board production machine according to the present disclosure, the first control application can be installed in the operating system of the first control device, the second control application can be installed in the operating system of the second control device, the operating system of the second control device can notify the first control device that the second breaker is turned off before stopping when the second breaker is turned off, and when the second breaker is turned on and the operating system is started during stopping, notify the first control device of the start of the operating system, and the second control application can be started to establish communication between the second control application and the first control application,When the operating system of the first control device receives a notification from the second control device that the second breaker is being turned off, the operating system can be restarted. When the operating system receives a notification of the start-up from the second control device, the first control application can be started to establish communication between the first control application and the second control application. In this way, even if the second breaker is turned off and then turned back on, it is possible to smoothly establish communication between the first control application and the second control application.

[0041] The present disclosure is not limited to the form of the board production machine and may represent a form of a board production line.
