Description

[Technical Field]

[0001] The technology disclosed in this specification relates to a board production system and a method for inspecting a board processing machine. [Background technology]

[0002] For example, International Publication No. 2018 / 073952 discloses a board processing machine that performs operations for producing boards. Generally, board processing machines require periodic maintenance of each component of the machine. Examples of such maintenance include cleaning and replacing filters. The board processing machine has a fan for introducing air into the machine and discharging the air introduced into the machine, and the fan is equipped with a filter. The filter prevents dust and dirt from entering the machine. When the board processing machine is used, dust and dirt accumulate on the filter. Therefore, periodic filter maintenance is required. The timing of maintenance of each component of such a board processing machine is determined by the operator checking the condition of each component. Summary of the Invention [Problem to be solved by the invention]

[0003] The timing of maintenance for each part of a board working machine varies depending on the environment in which the board working machine is used, etc. However, parts of a board working machine that require maintenance may be located in a position that is difficult for an operator to visually check, or may be difficult for an operator to approach. In such cases, it is difficult for an operator to check the condition of the parts of the board working machine that require maintenance. Furthermore, even if an operator can check the parts that require maintenance, it may be difficult for the operator to determine whether the condition of the parts requires maintenance or does not require maintenance.

[0004] This specification discloses a technique for appropriately determining whether or not a board processing machine needs maintenance. [Means for solving the problem]

[0005] The board production system disclosed in this specification comprises a mobile body that is installed in a predetermined set area and includes a plurality of board work machines that perform work on boards, an inspection unit that is movable within the set area and performs predetermined inspection work on at least one of the plurality of board work machines, and a first communication unit that transmits inspection results from the inspection unit, and a management device that includes a second communication unit that receives the inspection results transmitted from the first communication unit, and an output unit that outputs the inspection results received by the second communication unit.

[0006] In the above-described board production system, inspection work is performed using a mobile object. Furthermore, the inspection results of the inspection work performed using the mobile object are transmitted to a management device. This eliminates the need for a worker to perform the inspection work or to determine whether maintenance is required based on the inspection results, and allows the management device to appropriately determine whether maintenance is required for the board production machine.

[0007] The present specification also discloses a method for inspecting at least one of a plurality of board work machines that perform work on boards, and the inspection method includes the steps of: arranging a movable body at a predetermined position within a set area in which the plurality of board work machines are installed; positioning the movable body arranged at the predetermined position relative to a board work machine to be inspected among the plurality of board work machines; inspecting the board work machine to be inspected by the positioned movable body; and transmitting inspection results obtained by the inspection step to a management device.

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

[0010] The board production system disclosed in this specification includes a mobile body that can move within a predetermined set area. For example, it may be difficult for workers to access areas such as the rear side of a board production machine. On the other hand, a mobile body can move to areas that are difficult for workers to access. Therefore, by using the mobile body, it is possible to properly inspect a board production machine that is located in a position that is difficult for workers to directly check. In addition, the mobile body transmits inspection results performed by the inspection unit to a management device. This allows the management device to check the inspection results and determine whether maintenance is required for the board production machine. This reduces the burden on workers and enables maintenance of the board production machine at an appropriate time.

[0011] In the board production system disclosed in this specification, the board working machine may include a board working unit that performs work on the board, a housing that accommodates the board working unit and has an air intake, and a filter that is removably attached to the air intake. The inspection unit may be a camera. The inspection work may involve photographing the filter attached to the air intake with the camera. The inspection result may be an image of the filter photographed by the camera. With this configuration, the management device acquires an image of the filter installed in the board working machine. This allows the management device to appropriately determine whether maintenance is required for the filter installed in the board working machine.

[0012] In the board production system disclosed in this specification, the air intake may be provided on the back, top, or side of the housing. The mobile object may be an aircraft that flies within a set area. With this configuration, the camera can capture images of the back, top, or side of the housing as the mobile object flies. The back, top, or side of the housing may be difficult for workers to see. This allows the condition of a filter located in a position that is difficult for workers to see to be properly inspected.

[0013] In the board production system disclosed in this specification, the management device may further include an input unit through which an operator inputs a control command for controlling the moving body. The second communication unit may transmit the control command input from the input unit to the first communication unit. The moving body may further include a drive unit for moving the moving body and a control unit for controlling the drive unit based on the control command received by the first communication unit. With this configuration, the operator can operate the moving body from the management device. This allows the operator to properly perform inspection work via the moving body.

[0014] In the board production system disclosed in this specification, the board work machine may include a board work unit that performs work on the board. The inspection unit may be an acoustic device capable of converting sound into an electrical signal. The inspection work may involve converting sound generated from the board work unit into an electrical signal using the acoustic device. The inspection result may be an audio signal obtained by converting sound generated from the board work unit into an electrical signal. With this configuration, the management device acquires the audio signal obtained by converting sound generated from the board work machine into an electrical signal. For example, if an abnormality occurs in a device (e.g., air equipment, motor, etc.) installed in the board work machine, an abnormal sound that is different from normal will be generated. By acquiring the audio signal, the management device can appropriately determine whether maintenance is required for the device installed in the board work machine (whether or not an abnormal sound is generated).

[0015] In the board production system disclosed in this specification, the management device may further include a determination unit that determines the state of the board work machine that has been inspected based on the inspection results received by the second communication unit. With this configuration, the determination unit in the management device can determine the state of the board work machine. Therefore, the management device can automatically determine whether maintenance is required for the board work machine. [Example]

[0016] Example 1 A board production system 1 according to an embodiment will be described with reference to the drawings. As shown in Fig. 1, the board production system 1 includes a plurality of component mounters 10 arranged in a predetermined setting area 60, a drone 50, and a management device 70 installed in a location different from the setting area 60.

[0017] First, the component mounter 10 will be described with reference to Figure 2. The component mounter 10 is a device that mounts electronic components 4 onto a circuit board 2. The component mounter 10 is also called an electronic component placement device or a chip mounter. Typically, the component mounter 10 is installed alongside other board work machines such as a solder printer and a board inspection machine, forming a continuous mounting line.

[0018] As shown in FIG. 2 , the component mounter 10 includes a component mounter 22, a touch panel 24, and a control device 26. The component mounter 22 is disposed within a housing 28 of the component mounter 10. The component mounter 22 includes multiple component feeders 12, a feeder holder 14, a mounting head 16, a head moving device 18, and a board conveyor 20. Each component feeder 12 accommodates multiple electronic components 4. The component feeders 12 are detachably attached to the feeder holder 14 and supply the electronic components 4 to the mounting head 16. The specific configuration of the component feeders 12 is not particularly limited. Each component feeder 12 may be, for example, a tape feeder that accommodates multiple electronic components 4 on a roll of tape, a tray feeder that accommodates multiple electronic components 4 on a tray, or a bulk feeder that randomly accommodates multiple electronic components 4 in a container.

[0019] The feeder holder 14 has multiple slots, and a component feeder 12 can be removably installed in each of the multiple slots. The feeder holder 14 may be fixed to the component mounter 10 or may be removably attached to the component mounter 10. The placement head 16 removably holds one or multiple suction nozzles 6, and uses the suction nozzles 6 to pick up electronic components 4 supplied by the component feeders 12 and place the electronic components 4 on the circuit board 2. At this time, the head moving device 18 moves the placement head 16 relative to the component feeders 12 and the circuit board 2. As a result, the electronic components 4 are picked up from a specific one of the multiple component feeders 12 and placed in a predetermined position on the circuit board 2. The board conveyor 20 loads, supports, and removes the circuit boards 2.

[0020] The touch panel 24 is a display device that provides the operator with various information about the component mounter 10, and is also an input device that accepts instructions and information from the operator. The control device 26 is configured using a computer equipped with a CPU and a storage device. The control device 26 controls each part of the component mounter 10. The touch panel 24 is installed on the front side (-Y direction side) of the housing 28, and the control device 26 is installed on the back side (+Y direction side) of the housing 28. The component mounter 10 is installed within the setting area 60 so that the operator can easily access the front side of the housing 28. Hereinafter, of the sides of the housing 28, the side on which the touch panel 24 is installed will be referred to as the front side of the housing 28, the side opposite the front side of the housing 28 will be referred to as the back side of the housing 28, and the other sides will sometimes simply be referred to as the side of the housing 28.

[0021] The component mounter 10 also has an intake fan 30, a filter 32, and an exhaust fan 34. The intake fan 30 is provided on the back surface of the housing 28. The intake fan 30 draws air from the outside of the housing 28 into the inside of the housing 28 (i.e., the inside of the component mounter 10). The filter 32 is attached to the intake fan 30. The filter 32 removes dust and dirt from the air drawn into the component mounter 10 by the intake fan 30. The exhaust fan 34 is provided on the top surface of the housing 28. The exhaust fan 34 exhausts air from the inside of the housing 28 (i.e., the inside of the component mounter 10) to the outside of the housing 28. Note that in this embodiment, the filter 32 is attached only to the intake fan 30, but a filter may also be attached to the exhaust fan 34.

[0022] Next, the drone 50 will be described with reference to Fig. 3. As shown in Fig. 3, the drone 50 includes a driving unit 52, an imaging device 54, a communication unit 56, and a control unit 58.

[0023] The drive unit 52 is equipped with multiple motors that respectively drive multiple propellers (shown in FIG. 1). Driving the drive unit 52 causes the multiple propellers to rotate, causing the drone 50 to fly. Furthermore, by individually controlling the rotation speed of the multiple propellers, the drone 50 can be moved to a desired height and direction. The drone 50 is equipped with various sensors (e.g., gyro sensors, acceleration sensors, altitude sensors, distance sensors, etc.). The control unit 58 controls the drive unit 52 based on the outputs of these sensors, thereby positioning (hovering) the drone 50 at a desired position and height relative to the component mounter 10.

[0024] The photographing device 54 includes a camera and multiple light sources. Specifically, the multiple light sources are a front light source and a side light source. The front light source is installed so as to illuminate the photographed object coaxially with the photographing direction of the camera. The side light source is installed so as to illuminate the photographed object at an angle to the photographing direction of the camera. When the measurement object is illuminated with a side light source, shadows are generated by the unevenness of the measurement object, allowing the contour of the measurement object to be photographed clearly. The photographing device 54 is used to photograph the filter 32 of the component mounter 10. Note that the side light source may be configured so that the illumination angle is changeable. Furthermore, the photographing device may be equipped with a single light source, or the single light source may be movable so as to illuminate the photographed object from the front or from an oblique angle.

[0025] The communication unit 56 can communicate with a communication unit 74 (described later) of the management device 70 via the Internet 100 (see FIG. 1). The communication unit 56 transmits images captured by the imaging device 54 (for example, a captured image of the filter 32 of the component mounter 10) to the communication unit 74. The communication unit 56 also receives control commands (described later) for the drone 50 transmitted from the communication unit 74. The communication unit 56 outputs the received control commands to the control unit 58.

[0026] The control unit 58 is configured using a computer equipped with a CPU and a storage device. The control unit 58 is connected to the drive unit 52, the photographing device 54, and the communication unit 56, and controls the drive unit 52, the photographing device 54, and the communication unit 56, respectively. Specifically, the control unit 58 controls the drive unit 52 based on a control command received by the communication unit 56. The control unit 58 also causes the communication unit 56 to transmit an image captured by the photographing device 54 to the communication unit 74 of the management device 70.

[0027] Next, the management device 70 will be described with reference to Fig. 4. The management device 70 is installed in a location different from the setting area 60 in which multiple mounters 10 are installed, and is under the management of, for example, the manufacturer of the mounters 10. As shown in Fig. 4, the management device 70 includes an input unit 72, a communication unit 74, a display 76, and a control unit 78.

[0028] Input unit 72 is an input device for inputting various instructions to board production system 1, and is configured to allow an operator to input control commands for controlling drone 50, for example. Note that input unit 72 is not particularly limited in its specific configuration as long as it is capable of inputting control commands for controlling drone 50. The control commands input to input unit 72 are output to control unit 78.

[0029] The communication unit 74 can communicate with the communication unit 56 of the drone 50 via the Internet 100. The communication unit 74 transmits control commands for the drone 50 input to the input unit 72 to the communication unit 56. The communication unit 74 also receives captured images transmitted from the communication unit 56. The communication unit 74 outputs the received captured images to the control unit 78.

[0030] The display 76 displays the image output from the control unit 78. Specifically, the display 76 displays the image captured by the imaging device 54 of the drone 50 received via the communication unit 74.

[0031] The control unit 78 is configured using a computer equipped with a CPU and a storage device. The control unit 78 is connected to the input unit 72, the communication unit 74, and the display 76, and controls the input unit 72, the communication unit 74, and the display 76, respectively. Specifically, the control unit 78 causes the communication unit 74 to transmit a control command for the drone 50 input to the input unit 72 to the communication unit 56 of the component mounter 10. The control unit 78 also causes the display 76 to display the captured image received by the communication unit 74.

[0032] Next, a method for inspecting the filter 32 of the component mounter 10 using the board production system 1 of this embodiment will be described. The filter 32 removes dust and other particles from the air drawn into the component mounter 10 by the intake fan 30. Therefore, as the component mounter 10 is used, dust and other particles gradually accumulate on the filter 32. If excessive dust and other particles accumulate on the filter 32, the filter 32 becomes clogged. Therefore, the filter 32 requires maintenance, such as cleaning or replacement, at appropriate intervals. However, the filter 32 is installed on the rear surface of the housing 28 of the component mounter 10 (see FIG. 2). The component mounter 10 is often installed so that it is difficult for workers to approach the rear surface of the component mounter 10. Therefore, in order for the worker to check the filter 32, the worker must move the component mounter 10 (for example, pull the component mounter 10 forward) so that the rear surface of the component mounter 10 can be visually inspected. Furthermore, some workers may find it difficult to determine whether maintenance is required for the filter 32, even after visually inspecting it. The following describes a method for properly checking whether the filter 32 needs maintenance.

[0033] First, a worker (hereinafter simply referred to as "worker") in the setting area 60 places the drone 50 in a predetermined position in the setting area 60 (for example, near the back of one of the multiple component mounters 10) and turns on the power switch (not shown) of the drone 50. This establishes communication between the drone 50 and the management device 70, and the drone 50 starts capturing images using the imaging device 54. Images captured by the imaging device 54 are transmitted as needed to the communication unit 74 of the management device 70 via the communication unit 56.

[0034] When the management device 70 receives the captured images from the drone 50, an operator (hereinafter simply referred to as "operator") at the location where the management device 70 is installed operates the drone 50 while checking the captured images. Specifically, the operator inputs a control command for the drone 50 via the input unit 72. The control command input to the input unit 72 is transmitted from the communication unit 74 to the communication unit 56 of the drone 50. The control unit 58 of the drone 50 controls the drive unit 52 in accordance with the received control command. As a result, the drone 50 moves in accordance with the operation of the operator.

[0035] The operator moves the drone 50 to a predetermined position while checking the captured image. Specifically, the operator moves the drone 50 to a position where the imaging device 54 of the drone 50 can capture an image of the filter 32 of one of the multiple mounters 10 to be inspected (i.e., the first mounter 10). The drone 50 and the management device 70 may each be equipped with a voice communication function (not shown), and the operator may move the drone 50 while communicating with a worker within the set area 60. Specifically, the operator may operate the drone 50 while confirming with the worker that there are no obstacles or other workers in the drone 50's entry path. The drone 50 may also be equipped with an alarm unit (not shown). The alarm unit may be configured to notify those in the vicinity that the drone 50 is flying, and may be, for example, a siren or a voice generating device. When the drone 50 is moved, the alarm unit can notify those around the drone 50 that the drone 50 is flying, thereby avoiding the risk of other workers coming into contact with the drone 50.

[0036] When the drone 50 moves to a position where it can photograph the filter 32 of the first mounter 10, the operator photographs the filter 32 with the photographing device 54 via the input unit 72. When photographing the filter 32, the operator first photographs the filter 32 with a front light source illuminating it. However, if the operator determines that the image photographed with the front light source illuminating the filter 32 does not clearly show the shadows on the filter 32 and makes it difficult to determine the state of the filter 32, the operator inputs a control command to the input unit 72 to photograph the filter 32 with a side light source illuminating it. Depending on conditions such as the installation position of the mounter 10 and the installation position of the lighting within the setting area 60, the filter 32 may be photographed more clearly when illuminated with a front light source, or may be photographed more clearly when illuminated with a side light source. While checking the photographed image, the operator adjusts the illumination of the filter 32 to obtain an image that is most suitable for determining the state of the filter 32. The captured image of the filter 32 is stored in a memory (not shown) of the control unit 78 of the management device 70. The captured image is taken by the drone 50. The drone 50 can enter places that workers cannot enter. Therefore, the state of the filter 32 installed on the back side of the component mounter 10 can be checked without changing the installation position of the component mounter 10.

[0037] Once the captured image of the filter 32 is stored, an evaluator (hereinafter simply referred to as "evaluator") different from the operator determines the state of the filter 32 from the captured image. If the operator is able to determine the state of the filter 32, the operator may determine the state of the filter 32. Some workers may not be able to accurately determine whether or not the filter 32 is in a state requiring maintenance. By having the evaluator (or an operator with the ability to make such determination) determine the state of the filter 32, the state of the filter 32 can be appropriately determined.

[0038] After photographing the filter 32 of the first mounter 10, the operator photographs the filter 32 of another mounter 10 (i.e., the second mounter 10) in the setting area 60. The method for photographing the filter 32 of the second mounter 10 is similar to the method for photographing the filter 32 of the first mounter 10, and therefore detailed description thereof will be omitted. Similarly, the operator photographs the filters 32 of all mounters 10 to be inspected in the setting area 60. If a filter is also attached to the exhaust fan 34, the operator also photographs the filter attached to the exhaust fan 34. The photographed images of the filters 32 are transmitted to the management device 70. The assessor determines the state of each filter 32 from the transmitted photographed images. In this embodiment, the photographed images are displayed on the display 76, but this configuration is not limiting. As long as the assessor can confirm the photographed images, the photographed images may be printed on paper or the like using a printing device or the like.

[0039] The assessment result for the filter 32 is reported to the worker. For example, if the condition of the filter 32 is poor and it is clogged, it is reported that immediate maintenance is required. Furthermore, if the condition does not require immediate maintenance but the filter is partially clogged, it is reported when maintenance should be performed depending on the degree of clogging. For example, it may be recommended that maintenance of the filter 32 be performed at the same time as maintenance of another part. Furthermore, if it is reported that maintenance is required, after the maintenance is completed, the drone 50 may photograph the filter 32 after maintenance, so that the operator can check the condition of the filter 32 after maintenance.

[0040] In this embodiment, the intake fan 30 and the filter 32 are provided on the back surface of the housing 28 of the component mounter 10, but the present invention is not limited to this configuration. For example, the intake fan and the filter may be provided on the top or side surface of the housing 28. In this case, if the drone 50 is used to photograph the filter provided on the top or side surface, the state of the filter can be appropriately determined in the same way as in this embodiment.

[0041] Furthermore, in this embodiment, an assessor determines the state of the mounter 10 (specifically, the state of the filter 32), but this configuration is not limited to this. The state of the mounter 10 may also be automatically determined by the control unit 78 of the management device 70. For example, the control unit 78 stores a photographed image of the filter 32 in its initial state (the state before use), and can compare the photographed image of the filter 32 in its initial state with the photographed image of the filter 32 taken by the photographing device 54 of the drone 50 to determine the state of the filter 32. Specifically, the control unit 78 may calculate the difference between the photographed image of the filter 32 in its initial state and the photographed image of the filter 32 taken by the photographing device 54, and determine that maintenance is required when the difference is greater than a predetermined value.

[0042] In addition, in this embodiment, the state of the filter 32 of the component mounter 10 is inspected, but the present invention is not limited to such a configuration. If the part can be inspected from a captured image, the inspection can be performed using the drone 50 in the same manner as in this embodiment.

[0043] Example 2 In the above-described first embodiment, the state of the filter 32 installed in the component mounter 10 is inspected, but the present invention is not limited to such a configuration. For example, the sound generated from the component mounter 10 may be inspected using a mobile object such as a drone.

[0044] 5, the drone 150 of this embodiment includes a driving unit 52, a microphone 154, a communication unit 56, and a control unit 58. Note that the driving unit 52, the communication unit 56, and the control unit 58 have the same configurations as the driving unit 52, the communication unit 56, and the control unit 58 of the first embodiment described above, and therefore detailed description thereof will be omitted.

[0045] The microphone 154 converts the sound generated from the component mounter 10 into an electrical signal. The drone 150 also includes a noise-canceling sound pickup microphone (not shown). By using the noise-canceling function to cancel the driving sound of the drive unit 52 of the drone 150 from the audio signal output from the microphone 154, the audio signal output from the microphone 154 becomes an electrical signal obtained by converting the sound generated from the component mounter 10 (sound excluding the driving sound of the drive unit 52). The audio signal output from the microphone 154 is transmitted to the management device 170 via the communication unit 56.

[0046] 6, the management device 70 of this embodiment includes an input unit 72, a communication unit 74, a speaker 176, and a control unit 78. Note that the input unit 72, the communication unit 74, and the control unit 78 have the same configurations as the input unit 72, the communication unit 74, and the control unit 78 of the first embodiment, and therefore detailed description thereof will be omitted.

[0047] The speaker 176 converts the audio signal received by the communication unit 74 from the communication unit 56 of the drone 150 into audio and outputs the converted audio.

[0048] The operator operates the drone 150 to move it to an appropriate position around the mounter 10. The microphone 154 then picks up the sound generated by the mounter 10. The sound picked up by the microphone 154 is converted into an audio signal and transmitted to the communication unit 74 of the management device 170 via the communication unit 56. The speaker 176 of the management device 170 converts the received audio signal into sound and outputs it. An evaluator (or an operator with the ability to judge) checks the output sound and determines whether it is normal. For example, if a malfunction or abnormality occurs in an air device, motor, or the like installed in the mounter 10, a sound different from normal may be generated. The evaluator checks the sound from the speaker 176 and determines whether an abnormality has occurred in the mounter 10. The determination result is reported to the operator. Note that the control unit 78 may automatically determine whether an abnormality has occurred. For example, the control unit 78 may store a normal audio signal converted from the sound generated by the component mounter 10 under normal conditions, and detect an abnormality from the difference between the normal audio signal and the audio signal converted from the sound received by the microphone 154.

[0049] In the above-described first and second embodiments, the inspection was performed on the component mounter 10, but the present invention is not limited to such a configuration. A similar inspection can be performed on any board work machine that performs work on the circuit board 2. For example, the drones 50 and 150 may be used to perform inspections on solder printing machines, board inspection machines, etc.

[0050] Furthermore, in the above-described first and second embodiments, the drones 50 and 150 are used to acquire images and audio of the inspection target of the component mounter 10, but the present invention is not limited to this configuration. For example, an autonomous vehicle capable of moving within the set area 60 may be used to acquire images and audio of the inspection target of the component mounter 10. In this case, too, an operator can remotely control the autonomous vehicle to appropriately acquire the desired images and audio. Furthermore, mobile bodies such as the drones 50 and 150 and the autonomous vehicle may be capable of moving within the set area 60 by autonomous driving. For example, the mobile body may store a map of the set area 60, and the mobile body may move along a predetermined route to acquire the desired images and audio.

The component mounter 10 in the embodiment is an example of a "board work machine," the component mounter 22 is an example of a "board work section," the intake fan 30 is an example of an "air intake," the drone 50 is an example of an "air vehicle," the communication section 56 is an example of a "first communication section," the microphone 154 is an example of an "acoustic device," the communication section 74 is an example of a "second communication section," the display 76 and the speaker 176 are examples of an "output section," and the control section 78 is an example of a "determination section."
