Description

[Technical field]

[0001] The technology disclosed in this specification relates to a technology for calculating the energy consumption of a component mounter. [Background technology]

[0002] Patent Document 1 discloses an equipment tact optimization method for reducing energy consumption in a component mounter. In the equipment tact optimization method, a reference tact is acquired, which is the equipment tact of one of the mounting processing devices that make up the mounting line, and an initial tact is acquired, which is the equipment tact when mounting processing is performed under standard mounting processing conditions. Furthermore, if the initial tact is less than the reference tact, mounting processing conditions are determined so that energy consumption is reduced in an equipment tact that does not exceed the reference tact.

[0003] [Patent Document 1] JP 2006-269754 A Summary of the Invention [Problem to be solved by the invention]

[0004] As one of the countermeasures against the recent climate change problem, for example, reduction of energy consumption is required. In order to reduce the energy consumption of a component mounter, a user needs to know the breakdown of the energy consumption of the component mounter in more detail. This specification provides a technology that allows a user to know the breakdown of the energy consumption of a component mounter in more detail. [Means for solving the problem]

[0005] This specification discloses a method for calculating energy consumption of a component mounter. The component mounter includes a first device that moves a component to a mounting position on a board, and a second device different from the first device. The calculation method includes a first calculation step of calculating a first energy consumption consumed by the first device in mounting the component, a second calculation step of calculating a second energy consumption consumed by the second device in mounting the component, and a display step of displaying the calculated first energy consumption and second energy consumption.

[0006] In the first device that moves a component to a mounting position on a board, for example, the energy consumption changes greatly depending on the speed at which the component is moved to the mounting position on the board. Specifically, if the speed at which the component is moved to the mounting position on the board increases, the energy consumption increases, and if the speed decreases, the energy consumption decreases. On the other hand, in the second device of the component mounter, even if the speed at which the component is moved to the mounting position on the board changes, the energy consumption does not change greatly compared to the first device. In the above calculation method, the first energy consumption consumed by the first device and the second energy consumption consumed by the second device are displayed separately. Therefore, according to the calculation method disclosed in this specification, the user can know the breakdown of the energy consumption of the component mounter (for example, the change in the breakdown of the energy consumption when the speed at which the component is moved to the mounting position on the board is changed, etc.) in more detail.

[0007] Also, a management device for a component mounter that executes the above-mentioned calculation method, a computer program for causing the management device to execute the calculation method, and a component mounting system including the management device and a component mounter are also novel and useful. [Brief description of the drawings]

[0008] [Figure 1] 1 is a schematic diagram of a component mounting system including a management device according to an embodiment. [Diagram 2] FIG. [Diagram 3] FIG. [Figure 4] 13 is a graph showing the relationship between power consumption and mounting time. [Diagram 5] 11 is a flowchart showing an example of a component mounting process. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The main features of the embodiment described below are listed below. Note that the technical elements described below are independent technical elements that exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.

[0010] The calculation method disclosed in this specification may be a method capable of calculating the energy consumption of the component mounter before the mounting of the component is executed. In this case, the calculation method may further include an acquisition step of acquiring a mounting program for executing the mounting of the component. In the first calculation step, the first energy consumption may be calculated using an output value of the first device included in the mounting program acquired by the acquisition step, and in the second calculation step, the second energy consumption may be calculated using a mounting time required to mount the component included in the mounting program acquired by the acquisition step.

[0011] The first energy consumed by the first device varies mainly according to the output value of the first device included in the mounting program. Meanwhile, the second energy consumed by the second device varies mainly according to the mounting time included in the mounting program. With this configuration, the first energy and the second energy are calculated based on the mounting program, so that the user can know the breakdown of the energy consumption of the component mounter in more detail before the components are mounted.

[0012] In the calculation method disclosed in the present specification, the mounting program may include a first program for mounting the component in a first mounting time, and a second program for mounting the component in a second mounting time different from the first mounting time. In the acquisition step, the first program and the second program may be acquired. Furthermore, in the first calculation step, a third consumed energy using a first output value of the first device included in the first program and a fourth consumed energy using a second output value of the first device included in the second program may be calculated. In the second calculation step, a fifth consumed energy using the first mounting time included in the first program and a sixth consumed energy using the second mounting time included in the second program may be calculated. In the display process, at least one of the first consumed energy, which includes the third consumed energy and the fifth consumed energy consumed in implementing the component according to the first program, and the second consumed energy, which includes the fourth consumed energy and the sixth consumed energy consumed in implementing the component according to the second program, may be displayed.

[0013] With this configuration, it is possible to compare the energy consumption when mounting is performed using different mounting programs and for different mounting times.

[0014] In the calculation method disclosed in the present specification, the display step may display a smaller one of the first consumed energy and the second consumed energy.

[0015] According to this configuration, it is possible to inform the user of the smaller energy consumption. However, in another embodiment, in the display step, the larger of the first and second consumed energies may be displayed.

[0016] The calculation method disclosed in this specification may include a time designation step of accepting designation of the mounting time. In this case, the mounting program may include the output value corresponding to the mounting time designated by the time designation step. Furthermore, in the first calculation step, the first consumed energy may be calculated using the output value corresponding to the mounting time designated by the time designation step, and in the second calculation step, the second consumed energy may be calculated using the mounting time designated by the time designation step.

[0017] According to this configuration, the energy consumption of the mounter is calculated based on the mounting time specified by the user, so that the user can know the energy consumption according to the mounting time specified by the user.

[0018] In the calculation method disclosed in the present specification, the first device may include a servo motor that moves a head drive device of the mounter along the surface of the board. In this case, in the first calculation step, the first consumed energy may be calculated by taking into account regenerative energy generated by the servo motor.

[0019] According to this configuration, it is possible to calculate the first energy more accurately by taking the regenerative energy into consideration.

[0020] (First Example) 1 shows a schematic diagram of a component mounting system 100 including a management device 50 according to the present embodiment. The component mounting system 100 includes five component mounters 10 in addition to the management device 50. The management device 50 is capable of communicating with each of the component mounters 10. The management device 50 is a computer that manages each of the component mounters 10. The management device 50 transmits a mounting program, which will be described later, to each of the component mounters 10, and causes each of the component mounters 10 to mount components.

[0021] A detailed structure of the component mounter 10 will be described with reference to FIG. 2. The component mounter 10 is a device that mounts a component 4 at a mounting position on a board 2. The component 4 is an electronic component, and the board 2 is a circuit board. As shown in FIG. 2, the component mounter 10 includes a fan 11, a component feeder unit 12, a feeder holder 14, a head unit 15 that includes a mounting head 16 and a head moving device 18, a touch panel 24, a vacuum pump 26, an imaging device 30, a board conveyor 20, a control device 22, and a battery V1. The fan 11 ventilates the inside of the component mounter 10. The component feeder unit 12 has a plurality of feeders arranged in the +X direction (i.e., the direction into the paper surface of FIG. 1), and each feeder stores a plurality of components 4. Each feeder of the component feeder unit 12 is detachably attached to the feeder holder 14 and supplies the components 4 to the mounting head 16.

[0022] The mounting head 16 includes a nozzle 6 and a Z-axis motor 17. The nozzle 6 is connected to a vacuum pump 26. The vacuum pump 26 creates a negative pressure inside the nozzle 6, causing the nozzle 6 to pick up the component 4. The Z-axis motor 17 moves the nozzle 6 along the Z-axis (i.e., in the vertical direction on the paper surface of FIG. 2). The Z-axis motor 17 moves the nozzle 6 toward and away from each feeder of the component feeder unit 12 or the surface of the board 2. The Z-axis motor 17 is a so-called servo motor, and includes a servo controller, a servo amplifier, and a motor, although not shown. The mounting head 16 can pick up the component 4 from the feeder by the nozzle 6, and can mount the component 4 picked up by the nozzle 6 at a mounting position on the board 2. The mounting head 16 is not limited to one having a single nozzle 6, and may be one having multiple nozzles 6.

[0023] The head moving device 18 includes a moving base 18a, an XY-axis motor 19, and an imaging device 30. The XY-axis motor 19 moves the moving base 18a along the XY plane. As a result, the mounting head 16 and the imaging device 30 fixed to the moving base 18a move along the XY plane. The XY-axis motor 19 is also a servo motor, like the Z-axis motor 17. In addition to functioning as a motor to move the moving base 18a, the XY-axis motor 19 also functions as a generator. For example, the XY-axis motor 19 generates electricity by utilizing regenerative power generated when the moving speed of the moving base 18a is reduced. The power generated by the regenerative power is stored in the battery V1.

[0024] The touch panel 24 displays various information related to the component mounter 10. The touch panel 24 also functions as an operation unit that receives various instructions from the user.

[0025] The imaging device 30 includes a camera 32, an illumination light source (not shown), and a prism (not shown). The camera 32 captures an image of the side surface of the component 4 sucked by the nozzle 6 from the side (i.e., from the right side of the paper surface in FIG. 1). For example, a CCD camera is used as the camera 32. The illumination light source is composed of an LED, and illuminates the imaging surface of the component 4.

[0026] The board conveyor 20 is a device that carries in, positions, and carries out the board 2. As an example, the board conveyor 20 in this embodiment has a pair of belt conveyors and a support device (not shown) that supports the board 2 from below. When mounting of components 4 in the component mounter 10 is completed, the board conveyor 20 carries out the board 2 to an adjacent component mounter 10.

[0027] The configuration of the management device 50 will be described with reference to Fig. 3. In this embodiment, the management device 50 is, for example, a terminal device such as a notebook computer, and includes an operation unit 52, a display 54, a memory 55, and a CPU 58. The management device 50 may be a desktop personal computer, or a terminal device such as a smartphone or PDA. The operation unit 52 accepts various instructions from a user. The display 54 displays various information related to each mounter 10.

[0028] The memory 55 is composed of a volatile memory and a non-volatile memory. The memory 55 stores a program 56 and power consumption information 57. The program 56 is a program for executing a component mounting process and the like, which will be described later with reference to FIG. 5. The power consumption information 57 includes information regarding the power consumption of the component mounter 10. The program 56 and the power consumption information 57 are stored in advance at the time of shipment of the management device 50. In a modified example, the program 56 and the power consumption information 57 may be stored in the memory 55 after shipment of the management device 50.

[0029] The power consumption information 57 includes, for example, the power consumption per unit time of each of the fan 11, touch panel 24, control device 22, and camera 32 of the component mounter 10. The power consumption information 57 also includes, for example, a calculation formula for the power consumption of each of the devices 17, 19, and 26 of the component mounter 10. The calculation formula is, for example, a formula for calculating the power consumption of each of the motors 17 and 19 based on the required torque and mounting time. The calculation formula is, for example, a formula for calculating the power consumption of the vacuum pump 26 based on the required displacement and mounting time.

[0030] The CPU 58 executes various processes according to the program 56. The CPU 58 functions as, for example, a first calculation unit 59F that calculates the power consumption of each of the devices 17, 19, and 26, a second calculation unit 59S that calculates the power consumption of each of the devices 11, 24, 22, and 32, and a display unit 59D that displays the calculated power consumption on the display 54.

[0031] The management device 50 is connected to the control devices 22 of the component mounters 10. The management device 50 transmits various information to the component mounters 10, and also receives various information from the component mounters 10.

[0032] Here, the power consumption in the component mounter 10 will be described with reference to Fig. 4. Fig. 4 is a graph showing a breakdown of the power consumption in the component mounter 10. In Fig. 4, the vertical axis indicates the power consumption value, and the horizontal axis indicates the mounting time. Fig. 4 shows the power consumption of two different patterns P1 and P2. In both patterns P1 and P2, the same number of components 4 are mounted in the same mounting positions, but the mounting times are different. Pattern P1 is the power consumption when the components 4 are mounted in mounting time T1. Pattern P2 is the power consumption when the components 4 are mounted in mounting time T2, which is shorter than mounting time T1.

[0033] The power consumption of pattern P1 includes power consumption E1, E11, E21, and E31. The power consumption of pattern P2 includes power consumption E2, E12, E22, and E32. The power consumption E1 and E2 indicate the power consumed by the fan 11, touch panel 24, control device 22, and camera 32 of the component mounter 10. The power consumption E11 and E12 indicate the power consumed by the XY-axis motor 19 of the component mounter 10. The power consumption E21 and E22 indicate the power consumed by the Z-axis motor 17. The power consumption E31 and E31 indicate the power consumed by the vacuum pump 26.

[0034] In recent years, there has been a demand for reducing power consumption in the component mounter 10. On the other hand, there is a demand for improving productivity of the component mounter 10 by increasing the mounting speed. The present inventors have made a detailed comparison of the relationship between power consumption and mounting time in the component mounter 10. As a result, it was discovered that there are cases in which the power consumption of the component mounter 10 increases even if the mounting time is shortened.

[0035] The fan 11 of the component mounter 10 rotates at a substantially constant speed while the component 4 is being mounted. The touch panel 24 also continues to display images while the component 4 is being mounted. The control device 22 also continues to execute processing while the component 4 is being mounted. The camera 32 also repeatedly captures images of the side of the component 4 while the component 4 is being mounted. In these devices 11, 24, 22, and 32, the power consumption does not change significantly while the component 4 is being mounted. Therefore, in these devices 11, 24, 22, and 32, the power consumption changes according to the mounting time. In other words, in these devices 11, 24, 22, and 32, the power consumption is substantially proportional to the mounting time. As can be understood by comparing the power consumptions E1 and E2 in FIG. 4, the power consumed by the fan 11, touch panel 24, control device 22, and camera 32 of the component mounter 10 decreases as the mounting time becomes shorter. Hereinafter, the devices 11, 24, 22, and 32 in which the implementation time and power consumption are approximately proportional to each other may be referred to as "power-invariant devices."

[0036] On the other hand, for example, when the mounting time is shortened, the XY-axis motor 19 moves the moving base 18a at high speed with a large torque. As a result, the power consumption of the XY-axis motor 19 increases. Furthermore, when the moving base 18a moves at high speed, the energy loss (for example, heat loss) that occurs when the moving base 18a changes direction increases. For this reason, as shown by the power consumptions E11 and E12 in FIG. 4, there are cases in which the XY-axis motor 19 outputs a large torque to shorten the mounting time, resulting in an increase in power consumption. In other words, the power consumption of the XY-axis motor 19 may not be proportional to the mounting time. Similarly, the power consumption of the Z-axis motor 17 and the vacuum pump 26 may also increase when the mounting time is shortened. Hereinafter, the devices 19, 17, and 26 in which the mounting time and the power consumption may not be proportional to each other may be referred to as "power consumption varying devices."

[0037] 4, the proportion of power consumption in the mounter 10 accounted for by the XY-axis motor 19, the Z-axis motor 17, and the vacuum pump 26 (i.e., devices with variable power consumption) is greater than the proportion of power consumption in the devices 11, 24, 22, and 32 (i.e., devices with fixed power consumption). Therefore, as can be seen by comparing the power consumption in pattern P1 with the power consumption in pattern P2, there are cases in which the mounter 10 increases power consumption by shortening the mounting time.

[0038] The component mounting process executed by the CPU 58 of the management device 50 will be described with reference to Fig. 5. The component mounting process is a process executed before the component mounter 10 mounts the component 4. The component mounting process is started in response to receiving an operation to start the component mounting process on the operation unit 52 of the management device 50. Since the component mounting process is executed before the component 4 is mounted, the user can know the details of the power consumption before executing the component mounting process.

[0039] In S10, the CPU 58 accepts input of mounting information from the user via the operation unit 52. The mounting information includes, for example, the type of components 4 to be mounted, the number of components 4 to be mounted, and the mounting positions at which the components 4 are mounted.

[0040] In S12, the CPU 58 generates a first program in accordance with the program 56. The first program is a program for mounting components 4 of the type and number included in the mounting information input in S10 in the shortest mounting time at the mounting positions included in the mounting information. Specifically, the first program includes, for example, the shortest mounting time, and the torque of the XY-axis motor 19, the torque of the Z-axis motor 17, and the displacement of the vacuum pump 26 for achieving the mounting time.

[0041] In S20, the CPU 58 calculates the power consumption of the power consumption varying device using the torque of the XY-axis motor 19, the torque of the Z-axis motor 17, and the displacement of the vacuum pump 26, which are included in the first program generated in S12. Here, when calculating the power consumption of the XY-axis motor 19, the CPU 58 calculates the power consumption taking into account the regenerative power described above. This makes it possible to calculate the power consumption of the XY-axis motor 19 more accurately by taking into account the regenerative power.

[0042] Next, in S22, the CPU 58 calculates the power consumption of the non-variable power consumption device by multiplying the implementation time included in the first program generated in S12 by the power consumption per unit time of the non-variable power consumption device included in the power consumption information in the memory 55.

[0043] In S24, the CPU 58 displays a power consumption screen SC1 on the display 54. As shown in Fig. 5, the power consumption screen SC1 includes a shortest mounting time T2, the power consumption of the variable power consumption device "1.6 KW", the power consumption of the fixed power consumption device "0.08 KW", the total value of both power consumptions "1.68 KW", a mounting time change button, and an OK button. The shortest mounting time T2 is the shortest mounting time included in the first program generated in S12. The mounting time change button is a button for receiving an instruction to change the mounting time from the user.

[0044] In S30, the CPU 58 monitors whether an instruction to change the mounting time is received. If the CPU 58 receives the selection of the mounting time change button, it determines YES in S30 and proceeds to S40. If the CPU 58 receives the selection of the OK button, it determines NO in S30 and proceeds to S60.

[0045] In S40, the CPU 58 displays a mounting time change screen SC2. The mounting time change screen SC2 includes a designation area SA1 for designating a mounting time, and an OK button. After accepting the designation of the mounting time from the user and then accepting the selection of the OK button, the CPU 58 proceeds to S42.

[0046] In S42, the CPU 58 generates a second program based on the mounting time specified in S40.

[0047] Furthermore, in S50, similarly to S20, the CPU 58 calculates the power consumption of the power consumption variation device using the torque of the XY-axis motor 19, the torque of the Z-axis motor 17, and the displacement of the vacuum pump 26, which are included in the second program.

[0048] Next, in S52, the CPU 58 calculates the power consumption of the non-variable power consumption device by multiplying the mounting time specified in S40 by the power consumption per unit time of the non-variable power consumption device included in the power consumption information in the memory 55. In this way, the CPU 58 calculates the power consumption for each of the first program that mounts the component 4 in the shortest mounting time T2 and the second program that mounts the component 4 in the specified mounting time T1 specified by the user. This makes it possible to compare the power consumption for different mounting times.

[0049] In S54, the CPU 58 displays a power consumption screen SC3 on the display 54. As shown in FIG. 5, the power consumption screen SC3 includes the specified mounting time T1 specified in S40, the power consumption of the variable power consumption device when the component 4 is mounted at the specified mounting time T1, 1.2 KW, the power consumption of the non-variable power consumption device, 0.1 KW, the total power consumption of 1.3 KW, and an OK button, in addition to the contents of the power consumption screen SC1 described above. Since the power consumption screen SC3 displays the power consumption corresponding to the shortest mounting time T2 and the power consumption corresponding to the specified mounting time T1, the user can compare the power consumption at different mounting times. In addition, the user can know the power consumption corresponding to the specified mounting time T1 specified by the user. After accepting the selection of either the shortest mounting time T2 or the specified mounting time T1 from the user, the CPU 58 proceeds to S60 when it accepts the selection of the OK button.

[0050] In S60, the CPU 58 transmits a program corresponding to the mounting time selected in S54 (i.e., either the first program or the second program) as a mounting program to a specific one of the five mounters 10. As a result, the specific mounter 10 mounts the components 4 on the board 2 based on the received program.

[0051] (Effects of this embodiment) In this way, the management device 50 of this embodiment displays the power consumption of the power consumption varying device and the power consumption of the power consumption fixed device separately on the power consumption screens SC1 and SC3. This allows the user to know the power consumption of the component mounter 10 in more detail. Furthermore, because these are displayed separately, the user can know that when the power consumption of the power consumption varying device is greater than the power consumption of the power consumption fixed device, the power consumption can be reduced by changing the mounting time (e.g., lengthening the mounting time).

[0052] Furthermore, the component mounting process described above allows the user to simulate power consumption before mounting the components 4. This allows the user to select a mounting program that includes an appropriate mounting time, taking into consideration the mounting time and power consumption that are allowable under conditions such as the production speed of other production lines, etc. This allows the power consumption in the component mounter 10 to be reduced.

[0053] (Correspondence) The power consumption varying devices (i.e., devices 17, 19, 26) and the power consumption fixed devices (i.e., devices 11, 24, 22, 32) are examples of the "first device" and the "second device", respectively. The power consumptions E11, E12, E21, E22, E31, and E32 are examples of the "first consumed energy". The power consumptions E1 and E2 are examples of the "second consumed energy". The torque and the displacement are examples of the "output value". The power consumptions of the power consumption varying devices calculated in S20 and S50 of FIG. 5 are examples of the "third consumed energy" and the "fifth consumed energy", respectively. The power consumptions of the power consumption fixed devices calculated in S22 and S52 of FIG. 5 are examples of the "fourth consumed energy" and the "sixth consumed energy", respectively.

[0054] The steps performed by the processing of S20 and S22 are examples of a "first calculation step" and a "second calculation step", respectively. The step performed by the processing of S24 is an example of a "display step". The step performed by the processing of S12 is an example of an "acquisition step". The step performed by the processing of S40 is an example of a "time designation step".

[0055] (Second Example) Next, the component mounting process executed by the management device 50 of the second embodiment will be described with reference to FIG. 5. Comparing the component mounting process of this embodiment with the component mounting process of the first embodiment, in the component mounting process of this embodiment, a power consumption screen SC4 is displayed in place of the power consumption screen SC3 of the first embodiment at S54, but the other processes are the same. In the power consumption screen SC4 of this embodiment, only the smaller power consumption (i.e., the power consumption corresponding to the specified mounting time T1) between the power consumption corresponding to the first program and the power consumption corresponding to the second program is displayed. This allows the user to know the smaller power consumption.

[0056] Points to note about this embodiment are described below. The above-described component mounting process may be executed by the control device 22 of the component mounter 10. In that case, in S60 of FIG. 5, the mounting process is executed instead of transmitting the mounting program.

[0057] In the above-described embodiment, the component mounting process is executed before mounting the component 4 on the board 2. However, in a modified example, the component mounting process may be executed after mounting the component 4 on the board 2. In this case, the CPU 58 may calculate the power consumption of the power consumption varying device and the power consumption fixed device based on the program actually used to mount the component 4, and display them separately. According to this modified example, the user can know the power consumption of the power consumption varying device and the power consumption of the power consumption fixed device in detail in the mounting program in which the component 4 is actually mounted. In another modified example, the power consumption of the power consumption varying device and the power consumption fixed device may be calculated based on, for example, the amount of power applied to each device, without being based on a program.

[0058] The power consumption screen SC1 may not include a mounting time change button. In this case, the CPU 58 may not execute the processes of S30 to S54. That is, the calculation method may not include a time designation step. In a further modified example, the CPU 58 may accept a designation of the mounting time when inputting the mounting information in S10. In this case, only the power consumption corresponding to the designated mounting time may be displayed on the power consumption screen SC1.

[0059] The XY-axis motor 19 is not limited to a servo motor. In this case, the CPU 58 does not need to calculate the power consumption of the XY-axis motor 19 taking into account the regenerative power in S20.
