Abstract

An electric tool system includes an electric tool device and a camera device. The electric tool device has a drive unit and an electric tool communication unit. The drive unit performs tightening work of tightening a tightening component to a work target. The electric tool communication unit performs communication with outside. The camera device has a fixing unit, an image capturing unit, and a camera communication unit. The fixing unit is removably attached to the electric tool device. The image capturing unit captures an image of at least the work target. The camera communication unit performs communication with the outside.

Claims (30)

1 . An electric tool system comprising:

an electric tool device having a drive unit that performs tightening work of tightening a tightening component to a work target using power from a power source and an electric tool communication unit that performs communication with outside;

a camera device having a fixing unit that is removably attached to the electric tool device, an image capturing unit that captures an image of at least the work target, and a camera communication unit that performs communication with the outside; and

a processor that controls at least one of the image capturing unit and the camera communication unit on the basis of an operating state of the drive unit, wherein

the camera device includes at least one of a sound sensor and a vibration sensor that senses a first operating state, as a sensing result, indicating whether the drive unit is (1) in operation, in which the drive unit performs the tightening work, or (2) not in operation, in which the drive unit does not perform the tightening work, and

the processor controls the at least one of the image capturing unit and the camera communication unit on a basis of the first operating state.

2 . The electric tool system according to claim 1 , wherein the image capturing unit captures an image of each of the work target and the tightening component.

3 . The electric tool system according to claim 1 , wherein

the camera device includes the processor,

the electric tool communication unit transmits, to the camera communication unit, an operating state signal output from the drive unit and representing a second operating state indicating whether the drive unit is (1) in operation, in which the drive unit performs the tightening work, or (2) not in operation, in which the drive unit does not perform the tightening work, and

the processor controls the at least one of the image capturing unit and the camera communication unit on a basis of the operating state signal received by the camera communication unit.

4 . The electric tool system according to claim 1 , wherein

the electric tool device includes the processor,

the processor produces a camera control signal that controls the at least one of the image capturing unit and the camera communication unit on a basis of an operating state signal output from the drive unit and representing a second operating state indicating whether the drive unit is (1) in operation, in which the drive unit performs the tightening work, or (2) not in operation, in which the drive unit does not perform the tightening work, and

the electric tool communication unit transmits the camera control signal to the camera communication unit.

5 . The electric tool system according to claim 1 , further comprising:

an external communication device having an external communication unit and the processor, wherein

the electric tool communication unit transmits, to the external communication unit, an operating state signal output from the drive unit and representing a second operating state indicating whether the drive unit is (1) in operation, in which the drive unit performs the tightening work, or (2) not in operation, in which the drive unit does not perform the tightening work,

the processor produces a camera control signal that controls the at least one of the image capturing unit and the camera communication unit on a basis of the operating state signal received by the external communication unit, and

the external communication unit transmits the camera control signal to the camera communication unit.

6 . The electric tool system according to claim 3 , further comprising:

a history storage device that stores history information of the tightening work, wherein

the camera device further includes a camera storage unit that stores the captured image generated by the image capturing unit on a basis of the sensing result, and

the processor controls the camera communication unit on the basis of the operating state signal to cause the captured image to be transmitted from the camera communication unit to the history storage device.

7 . A camera device comprising:

an image capturing unit that captures an image of a work target of tightening work to which a drive unit of an electric tool device tightens a tightening component using power from a power source;

a fixing unit that is removably attached to the electric tool device;

a camera communication unit that communicates with the outside;

at least one of a sound sensor and a vibration sensor that senses a first operating state, as a sensing result, indicating whether the drive unit is (1) in operation, in which the drive unit performs the tightening work, or (2) not in operation, in which the drive unit does not perform the tightening work,

a processor that controls the at least one of the image capturing unit and the camera communication unit on a basis of the first operating state.
