DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] (Embodiment 1) (1-1) Overview Hereinafter, an overview of a power tool system 1 according to an embodiment will be described with reference to FIGS.

[0012] 1, the power tool system 1 according to this embodiment includes a power tool device 2 and a camera device 3. The power tool system 1 according to this embodiment is used, for example, in an assembly line in a factory where product assembly work is performed. The use of the power tool system 1 is not limited to the above-mentioned assembly line, and may be used for other purposes.

[0013] The work target on which the power tool device 2 is used is, for example, an electrical appliance or furniture. In this embodiment, it is assumed that the work target has a plurality of tightening target locations, and a worker tightens a tightening part to each of the tightening target locations using the power tool device 2. Specifically, the tightening fixtures are screws, bolts, nuts, etc., and the tightening target locations are screw holes into which the tightening fixtures are tightened. In the following, this embodiment will be described assuming the power tool device 2 having a cylindrical body 23 and a grip 24 protruding radially from the circumferential surface of the body 23 as shown in FIG. 3.

[0014] The power tool device 2 has a drive unit 21 and a power tool communication unit 22. The drive unit 21 performs a fastening operation of fastening a fastening part to a work target by using power from a power source such as a motor in response to an operation by an operator. The power tool communication unit 22 communicates with the outside and transmits the operating state of the drive unit 21 to the camera device 3.

[0015] The camera device 3 has a fixing unit 31, an imaging unit 32, and a camera communication unit 33. The fixing unit 31 fixes the camera device 3 to the power tool device 2 in a detachable manner. The imaging unit 32 images at least the work target. In this embodiment, the imaging unit 32 images the work target around the fastening target location where the fastening work is performed. The camera communication unit 33 communicates with the outside and receives information on the operating state of the drive unit 21 from the power tool communication unit 22.

[0016] The camera device 3 further includes a camera control unit 4 that controls at least one of the imaging unit 32 and the camera communication unit 33. In this embodiment, the camera control unit 4 controls the imaging unit 32 based on the operation state of the drive unit 21 received by the camera communication unit 33, and causes the imaging unit 32 to generate a captured image.

[0017] As described above, in this embodiment, when the power tool device 2 or the camera device 3 becomes unusable due to the end of its life or a malfunction, the power tool device 2 or the camera device 3 can be individually replaced. Therefore, the power tool system 1 of this embodiment has an advantage that the power tool device 2 and the camera device 3 can be effectively utilized.

[0018] (1-2) Details Hereinafter, a detailed configuration of the power tool system 1 of the present embodiment will be described with reference to FIGS.

[0019] The power tool system 1 of this embodiment includes a power tool device 2 and a camera device 3, as shown in FIG.

[0020] The power tool device 2 is, for example, an electric impact wrench, and is capable of performing a fastening operation of fastening a fastening part to a work target. In this embodiment, the power tool device 2 has a drive unit 21 and a power tool communication unit 22. In addition, as shown in Fig. 2, the power tool device 2 may further have an attachment unit 25 for detachably attaching a camera device 3 that captures an image of a work target.

[0021] The driving unit 21 can perform a fastening operation of fastening a fastening part to a work target by using power from a power source. In this embodiment, the driving unit 21 has a motor as a power source, and is configured to rotate by the power of the motor. The driving unit 21 can perform an operation such as fastening or loosening a fastening part by rotating. The driving unit 21 outputs an operating state signal A1 indicating an operating state to the power tool communication unit 22.

[0022] The power tool communication unit 22 is configured to be able to communicate with the outside. The power tool communication unit 22 is a communication module capable of wireless communication, such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). In this embodiment, the outside with which the power tool communication unit 22 communicates is assumed to be a device other than the power tool communication unit 22. The power tool communication unit 22 communicates with the camera communication unit 33, and transmits an operation status signal A1 indicating the operation status of the drive unit 21 to the camera communication unit 33. Specifically, when the drive unit 21 completes the tightening operation, the operation status signal A1 indicating the completion of tightening is transmitted to the camera communication unit 33.

[0023] The fixing portion 31 fixes the camera device 3 to the power tool device 2. The fixing portion 31 in this embodiment has at least one of a locking structure for locking the camera device 3 to the power tool device 2, a fitting structure for fitting into the mounting portion 25 of the power tool device 2, and a clamping structure for clamping the mounting portion 25.

[0024] The position where the fixing unit 31 fixes the camera device 3 to the power tool device 2 may be anywhere on the power tool device 2 as long as the imaging unit 32 can capture at least an image of the work target. For example, the fixing unit 31 may fix the camera device 3 to an upper part of the body 23 of the power tool device 2 as shown in Fig. 3A, or may be provided on a lower part of the body 23 of the power tool device 2 and on the front side of the body 23 as shown in Fig. 3B.

[0025] The power tool system 1 further includes a camera control unit 4 that controls at least one of the imaging unit 32 and the camera communication unit 33 based on the operating state of the driving unit 21. The camera control unit 4 preferably includes a computer system. In the computer system, a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) reads and executes a program stored in a memory, thereby realizing some or all of the functions of the camera control unit 4. The computer system includes a processor that operates according to a program as a main hardware configuration. The type of processor is not important as long as it can realize the function by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). Here, it is called an IC or an LSI, but the name changes depending on the degree of integration, and it may be called a system LSI, a VLSI (Very Large Scale Integration), or an ULSI (Ultra Large Scale Integration). Field programmable gate arrays (FPGAs), which are programmed after the LSI is manufactured, or reconfigurable logic devices, which can reconfigure the connections within the LSI or set up circuit partitions within the LSI, can also be used for the same purpose. Multiple electronic circuits may be integrated on one chip or may be provided on multiple chips. Multiple chips may be integrated in one device or may be provided on multiple devices.

[0026] In this embodiment, the camera device 3 has a camera control unit 4, and the camera control unit 4 controls at least one of the imaging unit 32 and the camera communication unit 33 based on an operation state signal A1 received by the camera communication unit 33.

[0027] The imaging unit 32 is composed of, for example, a camera having an imaging element and a lens. The imaging unit 32 captures an image of at least the work object. In this embodiment, the imaging unit 32 captures an image of the work object and the fastening parts. Specifically, the imaging unit 32 generates an imaged image including the work object and the fastening parts for which the fastening work has been completed in its imaging range based on the control of the camera control unit 4. Based on the imaged image generated by the imaging unit 32, a person managing the fastening work can check whether the drive unit 21 has normally attached the fastening fixture to the work object.

[0028] The camera communication unit 33 is configured to communicate with the outside and receive information related to the operating state of the drive unit 21 from the power tool communication unit 22. The camera communication unit 33 is a communication module capable of wireless communication, such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). In this embodiment, the outside with which the camera communication unit 33 communicates is a device other than the camera communication unit 33, such as the power tool communication unit 22 or an information terminal held by the worker. The camera communication unit 33 communicates with the power tool communication unit 22 and receives a work state signal A1 from the power tool communication unit 22.

[0029] The power tool system 1 further includes a history storage device 5 that stores history information of the fastening work. The history storage device 5 stores the captured image generated by the imaging unit 32 as history information of the fastening work. In this embodiment, the history storage device 5 is assumed to be a server having a storage device and a communication device. The storage device is, for example, a magnetic core memory or a semiconductor memory. The communication device may be capable of communicating with the camera communication unit 33 via a wide area network such as the Internet. The communication method between the communication device and the camera communication unit 33 may be wireless communication using radio waves as a medium that complies with a communication standard such as Wi-Fi (registered trademark). In addition, the communication method between the communication device and the camera communication unit 33 may be wired communication that complies with a communication standard such as a wired LAN (Local Area Network). In this embodiment, the camera communication unit 33 transmits the captured image generated by the imaging unit 32 to the history storage device 5 based on the control of the camera control unit 4.

[0030] (1-3) Operation The operation of the power tool system 1 according to this embodiment will be described with reference to the sequence diagram of FIG.

[0031] First, the driving unit 21 starts the tightening operation (S11). After the driving unit 21 completes the tightening operation (S12), the power tool communication unit 22 transmits an operation state signal A1 indicating the completion of the tightening to the camera communication unit 33 (S13).

[0032] Then, the camera communication unit 33 receives the operation status signal A1 from the power tool communication unit 22 (S14). The camera control unit 4 confirms that the tightening operation is completed based on the operation status signal A1 received by the camera communication unit 33, and controls the imaging unit 32 (S15). Thereafter, the imaging unit 32, under the control of the camera control unit 4, captures an image of the work target for which the tightening operation has been completed, and generates a captured image (S16).

[0033] Thereafter, the camera communication unit 33 transmits the captured image generated by the imaging unit 32 to the history storage device 5 under the control of the camera control unit 4 (S17). This enables the power tool system 1 to store the captured image generated by the imaging unit 32 in the history storage device 5 as history information of the fastening work.

[0034] The sequence diagram of FIG. 4 is merely an example of the operation of the power tool system 1 of this embodiment, and the order of the processes may be changed as appropriate, or any of the processes may be omitted as appropriate.

[0035] (1-4) Variations The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved.

[0036] In the above-described embodiment, as shown in Fig. 5, the power tool device 2 may have the camera control unit 4, instead of the camera device 3 having the camera control unit 4. In this case, the drive unit 21 outputs an operation state signal A1 indicating an operation state to the camera control unit 4, and the camera control unit 4 creates a camera control signal A2 for controlling at least one of the imaging unit 32 and the camera communication unit 33 based on the operation state signal A1 indicating the operation state of the drive unit 21. Then, the power tool communication unit 22 transmits the camera control signal A2 to the camera communication unit 33. The imaging unit 32 captures an image of the work object and the fastened part for which the fastening work has been completed based on the camera control signal A2, and the camera communication unit 33 transmits the captured image generated by the imaging unit 32 to the history storage device 5.

[0037] The imaging unit 32 according to one embodiment may generate an image including the work target in its imaging range before the drive unit 21 starts the fastening work, in addition to the image including the work target in its imaging range after the drive unit 21 has completed the fastening work. In this case, each of the images captured at different timings is stored in the history storage device 5. Therefore, the person managing the fastening work can more accurately check whether the drive unit 21 has normally attached the fastening fixture to the work target.

[0038] The history storage device 5 according to one embodiment may be provided in the camera device 3. In this case, the history storage device 5 is assumed to be, for example, a semiconductor memory such as a flash memory. Alternatively, the history storage device 5 may be a memory card that is removable from the camera device 3. The camera communication unit 33 does not need to transmit the captured image generated by the imaging unit 32 to the history storage device 5, and the history storage device 5 can store the captured image generated by the imaging unit 32 without going through the camera communication unit 33.

[0039] Moreover, the history storage device 5 according to one embodiment may be provided in the power tool device 2. The camera communication unit 33 transmits the captured image generated by the imaging unit 32 to the power tool communication unit 22. Then, the history storage device 5 can store the captured image generated by the imaging unit 32 via the power tool communication unit 22.

[0040] (Embodiment 2) (2-1) Overview The power tool system 1 of embodiment 2 differs from the power tool system 1 of embodiment 1 in that it is equipped with an external communication device 6 having an external communication unit 61 and a camera control unit 4, and the power tool device 2 and the camera device 3 communicate via the external communication device 6.

[0041] (2-2) Details Hereinafter, a detailed configuration of the power tool system 1 according to the second embodiment will be described with reference to FIG.

[0042] The power tool system 1 of the present embodiment includes a power tool device 2 having a drive unit 21 and a power tool communication unit 22, a camera device 3 having a fixed unit 31, an imaging unit 32, and a camera communication unit 33, and an external communication device 6 having an external communication unit 61 and a camera control unit 4. Note that the drive unit 21 and the fixed unit 31 of the power tool system 1 of the second embodiment are similar to the drive unit 21 and the fixed unit 31 of the power tool system 1 of the first embodiment, and therefore a description thereof will be omitted.

[0043] The power tool communication unit 22 communicates with the external communication unit 61 and transmits an operation status signal A1 indicating the operation status of the drive unit 21 to the external communication unit 61. Specifically, when the drive unit 21 completes the tightening operation, the power tool communication unit 22 transmits an operation status signal A1 indicating the completion of tightening to the external communication unit 61.

[0044] The external communication unit 61 is a communication module capable of wireless communication, such as Bluetooth (registered trademark), Wi-Fi (registered trademark), etc. The external communication unit 61 of the present embodiment is configured to be capable of communicating with both the power tool communication unit 22 and the camera communication unit 33.

[0045] The camera control unit 4 generates a camera control signal A2 for controlling at least one of the imaging unit 32 and the camera communication unit 33, based on the operation status signal A1 received by the external communication unit 61 from the power tool communication unit 22. In this embodiment, the camera control unit 4 generates the camera control signal A2 for controlling the imaging unit 32, based on the operation status signal A1. Then, the external communication unit 61 transmits the camera control signal A2 to the camera communication unit 33.

[0046] Based on the camera control signal A2 received by the camera communication unit 33, the imaging unit 32 captures an image of the work object for which the fastening work has been completed and the fastened parts.

[0047] The camera communication unit 33 transmits the captured image generated by the imaging unit 32 to the history storage device 5.

[0048] The power tool system 1 of this embodiment further includes a history storage device 5 that stores the captured images generated by the imaging unit 32 as history information of the fastening work performed by the driving unit 21. The camera communication unit 33 transmits the captured images generated by the imaging unit 32 to the history storage device 5.

[0049] The configuration of the power tool system 1 according to the second embodiment can be appropriately combined with the configuration of the first embodiment (including the modified examples).

[0050] (2-3) Operation The operation of the power tool system 1 according to this embodiment will be described with reference to the sequence diagram of FIG.

[0051] First, the driving unit 21 starts the tightening operation (S21). After the driving unit 21 finishes the tightening operation (S22), the power tool communication unit 22 transmits an operation state signal A1 indicating the completion of the tightening to the external communication unit 61 (S23).

[0052] Then, the external communication unit 61 receives the work status signal A1 from the power tool communication unit 22 (S24). The camera control unit 4 confirms that the tightening work has been completed based on the work status signal A1 received by the external communication unit 61, and creates a camera control signal A2 for controlling the imaging unit 32 (S25). Next, the external communication unit 61 transmits the camera control signal A2 to the camera communication unit 33 (S26).

[0053] After the camera communication unit 33 receives the camera control signal A2 (S27), the imaging unit 32 captures an image of the work object for which the fastening work has been completed and the fastened parts based on the camera control signal A2 (S28). Then, the camera communication unit 33 transmits the captured image generated by the imaging unit 32 to the history storage device 5 (S29). As a result, the captured image generated by the imaging unit 32 of the camera device 3, which is detachable from the power tool device 2, can be stored in the history storage device 5 as history information of the fastening work performed by the drive unit 21.

[0054] The sequence diagram of FIG. 7 is merely an example of the operation of the power tool system 1 of this embodiment, and the order of the processes may be changed as appropriate, or any of the processes may be omitted as appropriate.

[0055] (Embodiment 3) (3-1) Overview The power tool system 1 according to the third embodiment differs from the power tool system 1 according to the first embodiment in that the camera device 3 has at least one of a sound sensor 34 and a vibration sensor 35 that detects the operating state of the drive unit 21.

[0056] (3-2) Details Hereinafter, a detailed configuration of the power tool system 1 according to the third embodiment will be described with reference to FIG.

[0057] The power tool system 1 of the present embodiment includes a power tool device 2 having a drive unit 21, a fixed unit 31, an imaging unit 32, a camera communication unit 33, at least one of a sound sensor 34 and a vibration sensor 35, and a camera control unit 4. In this embodiment, both the sound sensor 34 and the vibration sensor 35 are included. The drive unit 21 and the fixed unit 31 of the power tool system 1 of the third embodiment are similar to the drive unit 21 and the fixed unit 31 of the power tool system 1 of the first embodiment, and therefore description thereof will be omitted.

[0058] The sound sensor 34 and the vibration sensor 35 detect the operating state of the drive unit 21 .

[0059] The sound sensor 34 is configured to detect a sound generated when the drive unit 21 performs a tightening operation. The sound sensor 34 may be any device that converts sound into an electric signal, and may be, for example, a microphone. When the sound sensor 34 detects a sound, it transmits a sound detection signal A3 to the camera control unit 4. Specifically, the sound sensor 34 continues to transmit the sound detection signal A3 while it continues to detect a sound, and stops transmitting the sound detection signal A3 when it no longer detects a sound.

[0060] The vibration sensor 35 is configured to detect vibrations that occur when the drive unit 21 performs a fastening operation. The vibration sensor 35 may be any device that converts vibrations into an electric signal, and may be, for example, a speed sensor, an acceleration sensor, or a gyro sensor. When the vibration sensor 35 detects vibrations, it transmits a vibration detection signal A4 to the camera control unit 4. Specifically, the vibration sensor 35 continues to transmit the vibration detection signal A4 while it continues to detect vibrations, and stops transmitting the vibration detection signal A4 when it no longer detects vibrations.

[0061] In this embodiment, the camera control unit 4 controls the imaging unit 32 when the state transitions from a state in which both the sound detection signal A3 and the vibration detection signal A4 are being output to a stop state. Then, the imaging unit 32 captures an image of the work target and the fastened parts for which the fastening work has been completed.

[0062] The power tool system 1 of this embodiment further includes a history storage device 5 that stores the captured images generated by the imaging unit 32 as history information of the fastening work performed by the driving unit 21. The camera control unit 4 controls the camera communication unit 33 to transmit the captured images generated by the imaging unit 32 to the history storage device 5.

[0063] The configuration of the power tool system 1 according to the third embodiment can be appropriately combined with the configuration of the first embodiment (including the modified examples).

[0064] (3-3) Operation The operation of the power tool system 1 of this embodiment will be described with reference to the sequence diagram of FIG.

[0065] First, the driving unit 21 starts the tightening operation, and sound and vibration are generated (S31). The sound sensor 34 detects the sound of the tightening operation and transmits a sound detection signal A3 to the camera control unit 4. Similarly, the vibration sensor 35 detects the vibration of the tightening operation and transmits a vibration detection signal A4 to the camera control unit 4 (S32).

[0066] Thereafter, the drive unit 21 completes the tightening operation, and the sound and vibration stop (S33). The sound sensor 34 no longer detects the sound of the tightening operation, and stops the sound detection signal A3. Similarly, the vibration sensor 35 no longer detects the vibration of the tightening operation, and stops the vibration detection signal A4 (S34).

[0067] Next, the camera control unit 4 controls the imaging unit 32 when the state transitions from a state in which both the sound detection signal A3 and the vibration detection signal A4 are output to a stopped state. Then, the imaging unit 32 captures images of the work object and the fastened parts for which the fastening work has been completed under the control of the camera control unit 4 (S35). The camera communication unit 33 transmits the captured images generated by the imaging unit 32 to the history storage device 5 (S36). As a result, the captured images generated by the imaging unit 32 of the camera device 3, which is detachable from the power tool device 2, can be stored in the history storage device 5 as history information of the fastening work performed by the drive unit 21.

[0068] The sequence diagram of FIG. 9 is merely an example of the operation of the power tool system 1 of this embodiment, and the order of the processes may be changed as appropriate, or any of the processes may be omitted as appropriate.

The drive unit 21 and the fixed unit 31 of the power tool system 1 of the fourth embodiment are similar to the drive unit 21 and the fixed unit 31 of the power tool system 1 of the first embodiment, and therefore description thereof will be omitted.

[0073] The sound sensor 34 or the vibration sensor 35 detects the operating state of the drive unit 21. In this embodiment, both the sound sensor 34 and the vibration sensor 35 detect the operating state of the drive unit 21.

[0074] The sound sensor 34 is configured to detect a sound generated when the drive unit 21 performs a tightening operation. The sound sensor 34 may be any device that converts sound into an electric signal, and may be, for example, a microphone. When the sound sensor 34 detects a sound, it transmits a sound detection signal A3 to the imaging control unit 36. Specifically, the sound sensor 34 continues to transmit the sound detection signal A3 while it continues to detect a sound, and stops transmitting the sound detection signal A3 when it no longer detects a sound.

[0075] The vibration sensor 35 is configured to detect vibrations that occur when the drive unit 21 performs a fastening operation. The vibration sensor 35 may be any device that converts vibrations into an electric signal, and may be, for example, a speed sensor, an acceleration sensor, or a gyro sensor. When the vibration sensor 35 detects vibrations, it transmits a vibration detection signal A4 to the imaging control unit 36. Specifically, the vibration sensor 35 continues to transmit the vibration detection signal A4 while it continues to detect vibrations, and stops transmitting the vibration detection signal A4 when it no longer detects vibrations.

[0076] The imaging control unit 36 ​​controls the imaging unit 32 to capture an image of at least the work target after the fastening operation based on the detection result of at least one of the sound sensor 34 and the vibration sensor 35. Since the power tool system 1 of the present embodiment includes both the sound sensor 34 and the vibration sensor 35, the imaging control unit 36 ​​controls the imaging unit 32 when the power tool system 1 transitions from a state in which both the sound detection signal A3 and the vibration detection signal A4 are output to a stopped state. Then, the imaging unit 32 generates captured images of the work target and the fastened parts for which the fastening operation has been completed based on the control of the imaging control unit 36. On the other hand, when the imaging control unit 36 ​​does not receive the sound detection signal A3 or the vibration detection signal A4, the imaging control unit 36 ​​does not control the imaging unit 32, and the imaging unit 32 does not capture an image.

[0077] The imaging control unit 36 ​​preferably includes a computer system. In the computer system, a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) reads and executes a program stored in a memory, thereby realizing some or all of the functions of the imaging control unit 36. The computer system includes a processor that operates according to a program as a main hardware configuration. The type of processor is not important as long as it can realize the function by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). Here, it is called an IC or an LSI, but the name changes depending on the degree of integration, and it may be called a system LSI, a VLSI (Very Large Scale Integration), or an ULSI (Ultra Large Scale Integration). A field programmable gate array (FPGA) that is programmed after the manufacture of the LSI, or a reconfigurable logic device that can reconfigure the connection relationship inside the LSI or set up the circuit partition inside the LSI, can also be used for the same purpose. A plurality of electronic circuits may be integrated into one chip, or may be provided on multiple chips. The multiple chips may be integrated into one device, or may be provided in multiple devices.

[0078] The camera storage unit 37 stores the captured image generated by the imaging unit 32 based on the detection result of at least one of the sound sensor 34 and the vibration sensor 35. The camera storage unit 37 of this embodiment is configured to store the captured image generated by the imaging unit 32. The camera storage unit 37 is, for example, a storage device such as a magnetic core memory or a semiconductor memory. The camera storage unit 37 may also be an auxiliary storage device such as an SSD (Solid State Drive) or an HDD (Hard Disk Drive).

[0079] The power tool system 1 of this embodiment further includes a history storage device 5 that stores the captured images generated by the imaging unit 32 as history information of the fastening work performed by the driving unit 21. The camera control unit 4 controls the camera communication unit 33 based on the operation status signal A1, and causes the camera communication unit 33 to transmit the captured images to the history storage device 5. In this embodiment, the camera control unit 4 determines whether or not to transmit the captured images stored in the camera storage unit 37 from the camera communication unit 33 to the history storage device 5 based on the operation status signal A1, and creates a camera control signal A2 that controls the camera communication unit 33.

[0080] The configuration of the power tool system 1 according to the fourth embodiment can be appropriately combined with the configuration of the first embodiment (including the modified examples).

[0081] (4-3) Operation In this embodiment, the sound sensor 34 is configured to detect the sound generated when the drive unit 21 performs the tightening operation, and the vibration sensor 35 is configured to detect the vibration generated when the drive unit 21 performs the tightening operation. However, it is possible that the sound sensor 34 or the vibration sensor 35 may make an erroneous detection. Therefore, the operation of the power tool system 1 of this embodiment will be described in the following cases: when both the sound sensor 34 and the vibration sensor 35 make a normal detection, when the sound sensor 34 or the vibration sensor 35 makes an erroneous detection, and when both the sound sensor and the vibration sensor make an erroneous detection.

[0082] (4-3-1) When both the sound sensor and the vibration sensor are detecting normally The operation of the power tool system 1 of this embodiment when the sound sensor 34 and the vibration sensor 35 normally detect the sound and vibration generated during the tightening operation will be described with reference to the sequence diagram of FIG.

[0083] First, the driving unit 21 starts the tightening operation, and sound and vibration are generated (S41). The sound sensor 34 detects the sound of the tightening operation and transmits a sound detection signal A3 to the camera control unit 4. Similarly, the vibration sensor 35 detects the vibration of the tightening operation and transmits a vibration detection signal A4 to the camera control unit 4 (S42).

[0084] Thereafter, the drive unit 21 completes the tightening operation, and the sound and vibration stop (S43). The sound sensor 34 no longer detects the sound of the tightening operation, and stops the sound detection signal A3 to the camera control unit 4. Similarly, the vibration sensor 35 no longer detects the vibration of the tightening operation, and stops the vibration detection signal A4 to the camera control unit 4 (S44).

[0085] Next, when the state where both the sound detection signal A3 and the vibration detection signal A4 are output is shifted to a stopped state, the imaging control unit 36 ​​controls the imaging unit 32. Then, the imaging unit 32 captures an image of the work object where the fastening parts are fastened, and the fastening parts, based on the control of the imaging control unit 36 ​​(S45). The camera storage unit 37 stores the captured image generated by the imaging unit 32 as captured image A (S46).

[0086] Thereafter, the power tool communication unit 22 transmits an operation status signal A1 indicating the completion of the fastening operation to the external communication unit 61 (S47). After the external communication unit 61 receives the operation status signal A1 (S48), the camera control unit 4 creates a camera control signal A2 for controlling the camera communication unit 33 to transmit the captured image A to the history storage device 5 based on the operation status signal A1 (S49). Then, the external communication unit 61 transmits the camera control signal A2 to the camera communication unit 33 (S4A).

[0087] After the camera communication unit 33 receives the camera control signal A2 (S4B), the camera communication unit 33 transmits the captured image A stored in the camera storage unit 37 to the history storage device 5 based on the camera control signal A2 (S4C). This allows the captured image generated by the imaging unit 32 of the camera device 3 to be stored in the history storage device 5 more quickly and accurately as history information of the fastening work performed by the drive unit 21.

[0088] The sequence diagram of FIG. 11 is merely an example of the operation of the power tool system 1 of this embodiment, and the order of the processes may be changed as appropriate, or any of the processes may be omitted as appropriate.

[0089] (4-3-2) When the sound sensor or vibration sensor detects something wrong The operation of the power tool system 1 of this embodiment when the sound sensor 34 or the vibration sensor 35 makes an erroneous detection will be described with reference to the sequence diagram of Fig. 12. First, a case where the sound sensor 34 makes an erroneous detection will be considered.

[0090] First, the sound sensor 34 detects a sound other than the tightening operation (for example, a sound generated when the power tool device 2 is moved or when an operation other than the tightening operation is performed) and transmits a sound detection signal A3 to the camera control unit 4. However, the vibration sensor 35 does not detect any vibration and does not transmit a vibration detection signal A4 (S51). After that, the sound sensor 34 no longer detects any sound other than the tightening operation and stops transmitting the sound detection signal A3 to the camera control unit 4. The vibration sensor 35 continues not to detect any vibration (S52).

[0091] Then, the imaging control unit 36 ​​receives only the sound detection signal A3 and does not receive the vibration detection signal A4. Therefore, the imaging control unit 36 ​​does not control the imaging unit 32, and the imaging unit 32 does not capture an image (S53).

[0092] Similarly, when the vibration sensor 35 makes an erroneous detection, the imaging control unit 36 ​​receives only the vibration detection signal A4 and does not receive the sound detection signal A3. Therefore, the imaging control unit 36 ​​does not control the imaging unit 32, and the imaging unit 32 does not capture an image.

[0093] The sequence diagram of FIG. 12 is merely an example of the operation of the power tool system 1 of this embodiment, and the order of the processes may be changed as appropriate, or any of the processes may be omitted as appropriate.

[0094] (4-3-3) When both the sound sensor and the vibration sensor detect an error The operation of the power tool system 1 of this embodiment when both the sound sensor 34 and the vibration sensor 35 make erroneous detections will be described with reference to the sequence diagram of FIG.

[0095] First, the sound sensor 34 detects a sound other than the fastening operation (for example, a sound generated when the power tool device 2 is moved or when an operation other than the fastening operation is performed) and transmits a sound detection signal A3 to the camera control unit 4. Similarly, the vibration sensor 35 detects a vibration other than the fastening operation (for example, a vibration generated when the power tool device 2 is moved or when an operation other than the fastening operation is performed) and transmits a vibration detection signal A4 to the camera control unit 4 (S61).

[0096] Thereafter, the sound sensor 34 no longer detects sounds other than those caused by the fastening operation, and stops the sound detection signal A3 to the camera control unit 4. Similarly, the vibration sensor 35 no longer detects vibrations other than those caused by the fastening operation, and stops the vibration detection signal A4 to the camera control unit 4 (S62).

[0097] Next, when the state where both the sound detection signal A3 and the vibration detection signal A4 are output is shifted to a stopped state, the imaging control unit 36 ​​controls the imaging unit 32. Then, based on the control of the imaging control unit 36, the imaging unit 32 captures an image of the work target where the fastening parts are fastened (S63). Then, the camera storage unit 37 stores the captured image generated by the imaging unit 32 as captured image B (S64).

[0098] However, since the tightening operation is not being performed, the camera communication unit 33 does not receive the camera control signal A2 (S65), and does not transmit the captured image B stored in the camera storage unit 37 to the history storage device 5 (S66).

[0099] Thereafter, when a preset certain time has elapsed since the camera storage unit 37 stored the captured image B, the camera storage unit 37 discards the captured image B (S67). For example, the preset certain time may be 30 seconds, or it may be shorter or longer than that.

[0100] This makes it possible to remove captured images generated due to malfunctions from the captured images to be transmitted to the history storage device 5.

[0101] The sequence diagram of FIG. 13 is merely an example of the operation of the power tool system 1 of this embodiment, and the order of the processes may be changed as appropriate, or any of the processes may be omitted as appropriate.

[0102] (4-4) Modifications In the above-described embodiment, the camera device 3 may have the camera control unit 4, rather than the external communication device 6 having the camera control unit 4. In this case, the camera control unit 4 may also function as the imaging control unit .

[0103] In the above-described embodiment, the external communication device 6 does not have the camera control unit 4, and the power tool device 2 may have the camera control unit 4.
