Description

Component mounter

The technology disclosed in this specification relates to a component mounter that mounts electronic components on a substrate.

Some component mounters that mount electronic components on a board can set operating conditions for mounting processing executed by the component mounter. In such a component mounting machine, the setting range (that is, setting authority) of the operating condition is different for each worker. For this reason, such a component mounting machine is provided with the identification part which identifies an operator, and the setting range is defined for every operator. When the worker is identified by the identification unit, the worker can set the operating condition of the mounting process within the setting range permitted for the worker. As such a technique, for example, Japanese Patent Application Laid-Open No. 2004-167669 discloses a technique in which only a registrant registered in advance can set operating conditions of an industrial machine.

The component mounter includes a device that performs a mounting process for mounting electronic components on a substrate, and a peripheral device that does not participate in the mounting process itself (for example, a display unit such as a display). The device that performs the mounting process needs to be operating during the mounting process. On the other hand, the peripheral device does not necessarily need to be operating during the mounting process, and may be operated when the peripheral device is required. For example, a peripheral device such as a display only needs to operate when an operator sets operating conditions and can display information necessary for the operator. However, the conventional technique has a problem that the peripheral device is in an operating state (hereinafter also referred to as a normal state) more than necessary, and consumes power unnecessarily. The present specification discloses a technique for reducing power consumption of a component mounter.

The component mounter disclosed in this specification mounts electronic components on a board. The component mounter includes an identification unit for identifying a pre-registered worker, an operation unit that can be operated when a pre-registered worker is identified by the identification unit, and a predetermined range in the vicinity of the component mounter. When the operation unit is operated in an operable state, a detection unit that detects whether or not the operator is positioned on the machine, a component mounting unit that executes a mounting process for mounting an electronic component on a board, and the operation unit are operated. Accordingly, an operating condition setting unit for setting an operating condition of a mounting process executed by the component mounting unit and a component mounting unit are provided separately from each other, and the operation unit is in a normal state when the operator registered in advance can operate it. On the other hand, a peripheral device that can be switched to a power saving state when an operator whose operation unit is registered in advance cannot be operated, and power supply to the peripheral device are controlled, and the detection unit is positioned within a predetermined range. If it is detected that the peripheral device is And a power supply unit to switch to et power saving state.

In the above component mounter, the operator registered in advance is identified by the identification unit. As a result, the operating condition of the mounting process can be set by an operation performed on the operation unit by a worker registered in advance. The power supply unit switches the peripheral device from the normal state to the power saving state when the detection unit detects that the worker is not located within the predetermined range. When the worker is not located near the component mounter, no operation from the worker is input. For this reason, a power supply part can reduce power consumption by switching a peripheral device to a power saving state.

The figure which shows schematic structure of the component mounting machine which concerns on an Example. Sectional drawing in the III-III line of FIG. The block diagram which shows the function of a control apparatus. The flowchart which shows an example of the process by which the component mounting machine sets the operating condition of the mounting process by the operator.

The main features of the embodiment described below are listed. The technical elements described below are independent technical elements and exhibit technical usefulness singly or in various combinations, and are limited to the combinations described in the claims at the time of filing. It is not a thing.

In the component mounter disclosed in this specification, the power supply unit may switch the peripheral device to the normal state when an operator registered in advance by the identification unit is identified while the peripheral device is in the power saving state. According to such a configuration, when an operator registered in advance is identified by the identification unit, the peripheral device is changed from the power saving state to the normal state. Thereby, when the operator registered in advance can operate the operation unit, the peripheral device can be brought into a normal state.

In the component mounting machine disclosed in this specification, the power supply unit switches the peripheral device to the normal state when the detection unit detects that the peripheral device is within the predetermined range in the power saving state. Also good. According to such a configuration, the peripheral device is in a normal state when an operator is located near the component mounter even in the power saving state. For this reason, as soon as the worker approaches the component mounter, the peripheral device is in a normal state, and the time for the worker to wait for the peripheral device to start can be shortened.

Hereinafter, the component mounter 10 according to the embodiment will be described. As shown in FIG. 1, the component mounter 10 is connected to the management device 8 so as to be communicable. The management apparatus 8 is communicably connected to the plurality of component mounters 10 and manages the plurality of component mounters 10. A component mounting line 100 is configured by the management device 8 and the plurality of component mounters 10. The management device 8 is configured using a computer including a CPU and a storage device. The management device 8 controls the entire component mounting line 100 by controlling the operation of each component mounting machine 10. That is, the management device 8 determines the type and position of the electronic component 4 to be mounted on the circuit board 2 by the component mounter 10 for each of the plurality of component mounters 10, and sends them to the component mounter 10. Instruct. When the component mounter 10 operates based on an instruction from the management device 8, the necessary electronic components 4 are mounted on the circuit board 2.

The component mounter 10 mounts the electronic component 4 on the circuit board 2. The circuit board 2 is sent from one end of the component mounting line 100 toward the other end. A predetermined electronic component 4 is mounted on the circuit board 2 in each component mounter 10. The circuit board 2 sent to the other end of the component mounting line 100 is shipped as a final product or sent to a subsequent process as a semi-finished product. A plurality of component feeders 12 can be installed in the component mounter 10. By installing the component feeder 12 in the component mounter 10, the electronic component 4 is supplied from the component feeder 12 to the component mounter 10. The component feeder 12 can be installed on any of the plurality of component mounting machines 10 in the component mounting line 100. The type of component feeder 12 to be installed in the component mounter 10 is determined by the management device 8.

2 to 4, the component mounter 10 includes a component mounting unit 22, a touch panel 24, an operator information acquisition unit 26, a sensor 28, and a control device 30.

2 and 3, the component mounting unit 22 includes a plurality of component feeders 12, a feeder holding unit 14, a mounting head 16, a head moving device 18, and a board conveyor 20. Each component feeder 12 accommodates a plurality of electronic components 4. The component feeder 12 is detachably attached to the feeder holding unit 14 and supplies the electronic component 4 to the mounting head 16. The specific configuration of the component feeder 12 is not particularly limited. Each component feeder 12 is, for example, a tape feeder that accommodates a plurality of electronic components 4 on a winding tape, a tray feeder that accommodates a plurality of electronic components 4 on a tray, or a plurality of electronic components 4 in a container. Any of the bulk type feeders that accommodates the ink at random.

The feeder holding unit 14 includes a plurality of slots, and the component feeder 12 can be detachably installed in each of the plurality of slots. The feeder holding unit 14 may be fixed to the component mounting machine 10 or may be detachable from the component mounting machine 10. The mounting head 16 detachably holds one or a plurality of suction nozzles 6, picks up the electronic components 4 supplied by the component feeder 12 using the suction nozzles 6, and mounts the electronic components 4 on the circuit board 2. At this time, the head moving device 18 moves the mounting head 16 with respect to the component feeder 12 and the circuit board 2. Thus, the electronic component 4 is picked up from the specific component feeder 12 among the plurality of component feeders 12, and the electronic component 4 is mounted at a predetermined position on the circuit board 2. The board conveyor 20 carries in, supports, and carries out the circuit board 2.

The touch panel 24 is a display device that provides various information of the component mounter 10 to the worker, and a user interface that receives instructions and information from the worker. For example, the touch panel 24 displays a different operation screen for each operation authority corresponding to the worker identified by the identification unit 42 described later. The touch panel 24 receives information input from the operation screen by the operator and outputs the information to the control device 30. Accordingly, the touch panel 24 is configured to be operable when an operator is identified by the identification unit 42 described later. The touch panel 24 is switched between an operable state and an inoperable state by a power supply unit 46 described later. In addition, although the component mounting machine 10 of a present Example is provided with the touch panel 24, it is not limited to such a structure. For example, a display device such as a display and an input device such as a keyboard and a mouse may be provided separately. The touch panel 24 is an example of an “operation unit” and “peripheral device”.

The worker information acquisition unit 26 (see FIG. 4) acquires information (hereinafter also referred to as worker information) about the worker used to identify the worker from the worker. The worker information may be any information that can identify each worker, and the type thereof is not particularly limited. For example, the worker information may be physical features such as a worker's fingerprint, iris, face, or a password set for each worker. The worker information acquisition unit 26 is configured to be able to acquire worker information. For example, in this embodiment, the worker information is a fingerprint of each worker, and the worker information acquisition unit 26 is a fingerprint sensor. When the worker information is the iris or face of each worker, the worker information acquisition unit 26 is a camera configured to be able to photograph the iris or face. When the worker information is a password set for each worker, the worker information acquisition unit 26 is an input device (for example, a keyboard) that can input the password. The worker information acquisition unit 26 is connected to the control device 30, and the worker information input to the worker information acquisition unit 26 is input to the control device 30.

The sensor 28 detects whether or not the worker is located within a predetermined range near the component mounter 10. Specifically, the sensor 28 detects whether or not the operator is located at a position where the touch panel 24 can be operated. For example, an optical sensor can be used as the sensor 28, and the sensor 28 detects whether or not the operator blocks the optical path. The sensor 28 is connected to the control device 30, and a signal from the sensor 28 is input to the control device 30. In this embodiment, the worker information acquisition unit 26, which is a fingerprint sensor, and the sensor 28, which is an optical sensor, are provided separately. However, the present invention is not limited to such a configuration. The worker information acquisition unit 26 and the sensor 28 may be integrally configured. For example, the worker information and the information related to the position of the worker are simultaneously acquired using a wireless medium such as a beacon, wireless communication, and a sound wave. It may be configured to. In this case, the worker carries the wireless communication terminal, and the wireless medium detects the wireless communication terminal carried by the worker, thereby simultaneously obtaining the worker information and the information regarding the position of the worker.

The control device 30 is configured using a computer including a memory 32 and a CPU 40. The memory 32 is provided with a registration information storage unit 34.

The registration information storage unit 34 stores information on workers registered in advance (hereinafter also referred to as registration information). In the present embodiment, the registration information storage unit 34 stores information related to the fingerprints of each worker as worker information for identifying the worker. Further, the registration information storage unit 34 combines worker information for identifying each worker (for example, information on the fingerprint of each worker in this embodiment) and operation authority permitted to the worker. I remember it. In this embodiment, the registration information is registered by the management device 8 and transmitted to the control device 30 of each component mounter 10 constituting the component mounting line 100.

Here, the operation authority is explained. The operation authority defines a setting range of work conditions that can be set by the worker, and a plurality of types of operation authority are set. The type of operation authority is not limited. For example, in this embodiment, four types of operation authority are set: operator authority, engineer authority, line manager authority, and designer authority.

The operator authority is an authority to perform an auxiliary operation (for example, supplementation of parts and instruments) necessary when the component mounting unit 22 executes the mounting process. For example, an operator having an operator authority can execute an operation of replenishing the electronic component 4 to the component feeder 12 when the component feeder 12 is out of components. The engineer authority is an authority to perform operations necessary for maintenance work of the component mounter 10 in addition to the operator authority. For example, an operator with engineer authority can operate a manual operation command that is required during maintenance. The line manager authority is an authority to change settings related to the production line and register and delete workers in addition to the engineer authority. For example, an operator having line manager authority can change the configuration of the component mounting line 100. Further, the worker having the line manager authority includes the worker registration information (that is, the worker information for identifying each worker (in this embodiment, the worker's fingerprint) and the operation authority given to the worker. ) Can be registered or deleted. The designer authority is an authority that can perform all operations related to operations and settings of the component mounter 10, and is, for example, an authority possessed by the manufacturer of the component mounter 10. For example, an operator having designer authority can forcibly operate the component mounting machine 10 in an emergency.

A calculation program is stored in the memory 32, and the CPU 40 functions as an identification unit 42, an operation condition setting unit 44, and a power supply unit 46 when the CPU 40 executes the calculation program.

The identification unit 42 determines whether or not the worker information acquired by the worker information acquisition unit 26 is stored in the registration information storage unit 34. Further, the registration information storage unit 34 stores the operation authority permitted to the worker along with the worker information. Therefore, when it is determined by the identification unit 42 that the identifier information for identifying the worker is stored in the registered information storage unit 34, the operation authority permitted to the worker is determined.

The operating condition setting unit 44 sets the operating condition of the mounting process executed by the component mounting unit 22. The operating conditions are input from the touch panel 24 by the operator. The operation condition setting unit 44 sets an operation condition of a mounting process executed by the component mounting unit 22 based on information input to the touch panel 24.

The power supply unit 46 controls power supply to the component mounting unit 22 and the touch panel 24. Specifically, when power supply to the component mounter 10 is started from an external power supply, the power supply unit 46 starts power supply to the component mounter 22. As a result, the component mounting unit 22 can execute the component mounting process. On the other hand, unlike the component mounting unit 22, the touch panel 24 only needs to be operable when an operator sets the work conditions for the mounting process, and while the component mounting unit 22 is executing the component mounting process. However, when the worker does not need to set the working conditions for the mounting process, it is not necessary to be in an operable state. For this reason, in this embodiment, the power supply unit 46 controls the supply of power to the touch panel 24 and switches between a state where the touch panel 24 can be operated and a state where the touch panel 24 cannot be operated. Hereinafter, a state in which power is supplied to the touch panel 24 by the power supply unit 46 and the touch panel 24 can be operated is referred to as a “normal state”, and a state in which no power is supplied and the touch panel 24 cannot be operated is a “power saving state”. May be called.

FIG. 5 is a flowchart showing an example of processing in which the operating conditions of the mounting processing are set by the worker. The operator sets the working conditions for the mounting process by operating the touch panel 24. The touch panel 24 only needs to be in a normal state when the worker sets the working conditions of the mounting process, and is in a power saving state except when the worker needs to set the working conditions of the mounting process. Yes. For this reason, in most cases, the touch panel 24 is in a power saving state when an operator attempts to set the working conditions of the mounting process. Therefore, when the operator sets the working conditions for the mounting process, first, the touch panel 24 needs to be switched from the power saving state to the normal state. Hereinafter, processing when the touch panel 24 is switched from the power saving state to the normal state and an operator inputs work conditions to the touch panel 24 will be described.

As shown in FIG. 5, first, the control device 30 determines whether or not worker information has been input to the worker information acquisition unit 26 (S12). The worker inputs worker information for identifying the worker himself / herself into the worker information acquisition unit 26. In this embodiment, since the worker information acquisition unit 26 is a fingerprint sensor, the worker causes the worker information acquisition unit 26 to read the worker's own fingerprint. The worker information acquisition unit 26 outputs the acquired worker information (that is, information regarding the read fingerprints of the worker) to the control device 30. When the worker information is not input from the worker information acquisition unit 26 (NO in step S12), the control device 30 waits until the worker information is input from the worker information acquisition unit 26.

When worker information is input from the worker information acquisition unit 26 (YES in step S12), the identification unit 42 is a worker in which a worker related to the worker information input in step S12 is registered in advance. It is determined whether or not (S14). That is, the identification unit 42 determines whether or not the worker information input in step S12 is stored in the registration information storage unit 34. If the worker information input in step S12 is not stored in the registration information storage unit 34 (NO in step S14), the worker does not have the authority to set the operating conditions of the component mounter 10. Is determined, and the setting of the operating condition of the component mounter 10 is rejected. For this reason, it returns to step S12 and repeats the process from step S12.

When the worker information input in step S12 is stored in the registration information storage unit 34 (YES in step S14), the power supply unit 46 switches the touch panel 24 from the power saving state to the normal state (S16). . Specifically, the power supply unit 46 switches from a state in which power is not supplied to the touch panel 24 to a state in which power is supplied. As a result, the touch panel 24 becomes operable by the operator. At this time, the touch panel 24 displays a screen according to the operation authority given to the worker. As described above, the registration information storage unit 34 is combined with worker information for identifying each worker (in this embodiment, the worker's fingerprint) and the operation authority permitted to the worker. Registration information is stored. A different operation screen is displayed on the touch panel 24 for each operation authority corresponding to the identified worker. Thereby, the worker can set the operation condition within the range of the operation authority permitted by the worker. For example, when the authority granted to the worker is an operator authority, the operator is displayed on the touch panel 24 so that only auxiliary operations necessary when the component mounting unit 22 executes the mounting process can be set.

When the touch panel 24 is in a normal state, the control device 30 determines whether or not the operator has input work condition settings to the touch panel 24 (S18). When the operator inputs work condition settings on the touch panel 24 (YES in step S18), the control device 30 acquires the input information (S20). The operation condition setting unit 44 sets the operation condition of the mounting process executed by the component mounting unit 22 based on the input information. And the control apparatus 30 performs a process according to the set operating condition. On the other hand, when the operator does not input the work condition setting on the touch panel 24 (NO in step S18), the process skips step S20 and proceeds to step S22.

Next, the control device 30 determines whether or not the sensor 28 has detected an operator (S22). Specifically, the control device 30 determines whether or not the sensor 28 has detected an operator based on a signal input from the sensor 28. When the sensor 28 detects the worker (YES in step S22), the worker is present within a predetermined range (that is, a position where the touch panel 24 can be operated). For this reason, it is determined that the operation by the operator has not been completed, the process returns to step S18, and the processes of steps S18 to S22 are repeated.

On the other hand, when the sensor 28 does not detect the worker (NO in step S22), the worker does not exist within the predetermined range (that is, the position where the touch panel 24 can be operated), and from within the predetermined range. I'm away. For this reason, it is determined that the operation by the operator has ended, and the control device 30 switches the touch panel 24 from the normal state to the power saving state (S24). Thereby, after the operator leaves the touch panel 24 from a position where the touch panel 24 can be operated, the normal state can be avoided more than necessary, and the power consumption can be reduced.

In the present embodiment, the touch panel 24 is switched from the power saving state to the normal state when the identification unit 42 identifies that the worker is a registered worker, but the present invention is not limited to such a configuration. . For example, when the sensor 28 detects that the worker is within a predetermined range, the touch panel 24 is switched from the power saving state to the normal state, and then whether or not the worker is registered in advance by the identification unit 42. You may identify.
