Description

Technical Field

[0001] This invention relates to a power control device for a component placement machine, specifically a power control device for a component placement machine that enables remote control of the power supply of the entire component placement machine, which is composed of wiring, via a network. Background Technology

[0002] A typical component placement machine uses negative pressure to attract electronic components to the front end of an adsorption nozzle. The head equipped with the adsorption nozzle is moved to a predetermined coordinate on the substrate, and positive pressure is applied to the front end of the adsorption nozzle at that position, thereby placing the electronic components onto the desired position on the substrate.

[0003] Typically, multiple component placement machines used for adsorbing, moving, and attaching electronic components are arranged in succession to form a line, and multiple such lines can be provided.

[0004] That is, multiple component placement machines are usually arranged and operated continuously on at least one line. When it is desired to turn the power on / off of the component placement machines consisting of at least one line, there is a problem that the staff needs to manually operate the power supply and operating software of each device one by one.

[0005] Furthermore, at the start of production, there is a need for servo activation and axis return time, and additional time may be required for selecting production programs. Therefore, the required time increases proportionally with the number of component placement machines, resulting in the consumption of manpower and time and reduced work efficiency.

[0006] Therefore, there is a need for a remote control device for a component placement machine that can centrally control the power supply to turn on / off, rather than turning the power supply on / off for each individual device, and can remotely control the power supply.

[0008] Japanese Patent No. 6067840 (Granted on January 6, 2017) Summary of the Invention

[0009] Technical issues

[0010] The technical problem to be solved by the present invention is to provide a power control device for a component placement machine that can centrally control the power supply of the equipment equipped in the component placement machine and prevent accidents caused by accidental power-on / off.

[0011] The technical problems to be solved by the present invention are not limited to those mentioned above. Those skilled in the art can clearly understand other technical problems not mentioned through the following description.

[0012] Technical solution

[0013] A power control device for a component mounter according to an embodiment of the present invention may include: at least one line configured with a device for mounting components; a power control module for controlling the power supply of the device; a line power controller for applying the power on / off state of each of the lines to the power control module at least in a first manner, or receiving the power on / off state of the power control module; and a remote control module for controlling the power supply of the line and the power controller via Ethernet.

[0014] The power control module may be configured to control the power supply of each of the devices, respectively connected to the devices.

[0015] The power control module may include: an actuator; a main circuit blocker connected to the actuator; and a safety module installed on the actuator, which shares the signal of the circuit's state and enables the setting to prohibit state changes.

[0016] The line power controller may be equipped with a PLC to process communication and I / O signals, and may transmit power on / off signals to each of the power control modules, and may receive the status of each of the power control modules and apply it to the remote controller.

[0017] To enable the device from a closed state, the remote control module can receive a start-up command to begin production. Based on the application of the start-up command, the remote control module can apply an execution command to the operating system of the component placement machine, allowing the device to prepare for the production program for producing the component.

[0018] When the device is in the off state, the individual states of the device can be aggregated to the line power controller through the power control modules that are individually connected to each of the devices, and applied to the remote control module.

[0019] The various operational states that apply the drive command, or apply the execution command, or prepare the production program can be applied to the line power controller. When the applied result value is abnormal, the various operations can be interrupted and an error occurs.

[0020] When an end command is applied to shut down the device from the on state, the remote control module can apply a shutdown drive command to stop production. According to the shutdown drive command, the remote control module can apply a servo shutdown command to the operating system of the component placement machine, and the power control module can be applied to shut down, so that the device can end the production of the component.

[0021] The various operational states that apply the shutdown drive command, the servo shutdown command, or terminate the production of the component can be applied to the line power controller. When the applied result value is abnormal, the various operations can be interrupted and an error occurs.

[0022] Specific details of other embodiments are included in the detailed description and accompanying drawings.

[0023] Beneficial effects

[0024] The power control device of the component placement machine according to the embodiment of the present invention described above has the advantage of being able to remotely control the power supply of all equipment on the line and complete production preparation work.

[0025] Furthermore, the power control device of the component placement machine according to an embodiment of the present invention has the advantage that staff can manage all line equipment in one place and can save production preparation time.

[0036] Hereinafter, based on embodiments of the present invention, the present invention will be described with reference to the accompanying drawings illustrating the power control device 100 for a component placement machine.

[0037] Figure 1 This is a schematic configuration diagram of a power control device 100 for a component placement machine according to an embodiment of the present invention. Figure 2 This is a schematic diagram illustrating the configuration of the line power controller 130 in the power control device 100 of a component placement machine according to an embodiment of the present invention. Figure 3 This is a schematic diagram illustrating the configuration of the power control module 120 in the power control device 100 of a component placement machine according to an embodiment of the present invention.

[0038] Reference Figures 1 to 3According to an embodiment of the present invention, the power control device 100 of the component placement machine may include a line 110, a power control module 120, a line power controller 130, and a remote control module 140.

[0039] The line 110 is constructed using a device 111 for mounting components, and may be equipped with at least one.

[0040] The power control module 120 may be configured to be connected to the devices 111 respectively to control the power supply of each of the devices 111, and may be configured to apply the state of the devices 111 to the line power controller 130.

[0041] Specifically, the power control module 120 may include an actuator 121, a main circuit breaker (MCB) 122, and a safety module 123.

[0042] The state of the device 111 can be applied to the line power controller 130 (described later) by the on / off drive of the actuator 121, and commands from the line power controller 130 can be received by the on / off drive of the actuator 121.

[0043] The main circuit blocker 122 may be configured to connect to the actuator 121 to prevent accidents caused by unexpected power-on / off signals.

[0044] The safety module 123 may be equipped with a signal connected between the actuator 121 and the device 111 to share the state of the line 110, and implement a state change prohibition setting.

[0045] Specifically, the power control module 120 is equipped with voltage and current capacity capable of remotely controlling the power supply of the device 111, and can add signals and functions to prevent accidents. The power control module 120 (specifically, the actuator 121) is implemented to acknowledge status signals and operate so that the power supply to the device 111 will not be shut off due to an accident during normal operation. Furthermore, the power control module 120 (specifically, the safety module 123) implements a status change prohibition setting function to prevent accidents caused by externally turning on the power supply during maintenance of the device 111; this status change prohibition setting function can be manually set in the device 111.

[0046] The line power controller 130 may be configured to apply the power supply of each line 110 to the power control module 120 for on / off states at least in a first manner, or to receive the on / off states of the power control module 120.

[0047] The line power controller 130 can be designed as a programmable logic controller (PLC). Accordingly, the line power controller 130 can be configured to process communication and I / O signals. The line power controller 130 can be configured to transmit power on / off signals to each of the power control modules 120, receive the status of each of the power control modules 120 and summarize the status, and apply the summarized result value to the remote control module 140.

[0048] The remote control module 140 can be configured to control the power supply of the line 110 and the power controller via Ethernet. Specifically, the remote control module 140 can be configured to connect to the line power controller 130 via Ethernet, or to each device 111 to control the power supply. Therefore, it can be configured to not only control the power supply of each device 111 via the power control module 120, but also to control the power supply of each device 111 individually.

[0049] In this way, the power supply of all equipment 111 of the line 110 can be remotely controlled, thereby enabling the completion of additional production preparations in advance.

[0050] Figure 4 This is a flowchart of the power-on operation of the power control device 100 of the component placement machine according to an embodiment of the present invention. Figure 5 This is a flowchart of the power-off operation in the component mounting and power control device 100 according to an embodiment of the present invention.

[0051] Reference Figure 4 and Figure 5 The power-on and power-off operation processes of this invention can be observed.

[0052] First, observe the power-on operation process of the power control device 100 of the component placement machine according to an embodiment of the present invention. The individual states of each of the devices 111 can be applied to the line power controller 130 by the power control module 120 and summarized. The summarized result value can be applied to the remote control module 140 by the line power controller 130 and confirmed.

[0053] If device 111 is in a powered-off state, the remote control module 140 can issue a start-up command to begin production. Based on the start-up command for device 111, an execution command can be issued to the operating system of the remote control module 140. Through the execution commands issued to the operating system of device 111 by the remote control module 140, the state of each device 111 is reset (origin restored), and preparation for the production program for the production components can be executed.

[0054] While each step is performed, the component placement machine or line power controller 130 communicates with each other to confirm the operation status. If an abnormal state is sensed during the confirmation of each operation status, the step can be stopped and an error will occur.

[0055] Furthermore, observing the power-off operation process of the power control device 100 of the component placement machine according to an embodiment of the present invention, the individual states of each device 111 can be applied to the remote control module 140 and confirmed by the power control module 120 through the line power controller 130.

[0056] If the device 111 is in the ON state, the remote control module 140 can issue an end command to terminate production. Based on the issuance of the end command, a servo shutdown command can be issued. An operating system shutdown command can be issued by issuing the servo shutdown command. When the operating system shutdown command is issued, a command to shut down the power control module 120 can be issued. Accordingly, the power to each device 111 can be shut down. Furthermore, while communicating with the component placement machine or line power controller 130, the operation status is confirmed during each step. If an abnormal state is sensed, the step can be terminated and an error can occur.

[0057] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical concept or essential features of the invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
