Abstract

A machining system of the present invention includes: a subject to be machined, said subject having a housing and a light source provided in the housing; and a fitting device for fitting a fixing member in the housing. The subject to be machined has a light output port for outputting, to the outer side of the housing, output light outputted from the light source, said light output port being an opening formed in the housing. The fitting device is provided with: a fitting mechanism for fitting the fixing member in the housing by being driven; a light receiving device for receiving the output light outputted from the light output port; and a drive control unit for controlling the drive of the fitting mechanism on the basis of the results of the light reception performed by the light receiving device.

First claim

a target device having a housing and a light source disposed within the housing; and a fitting device configured to fit a fixing member in the housing, wherein the target device has at least one light exit opening provided in the housing and configured to let out light emitted by the light source to an exterior of the housing as emitted light, and the fitting device includes:
a fitting mechanism configured to be driven to fit the fixing member in the housing;
at least one light receiver configured to receive the emitted light that has exited through the at least one light exit opening; and
a drive controller configured to control driving of the fitting mechanism based on a result of light reception by the at least one light receiver.

2 . The machining system according to claim 1 , Wherein
the drive controller drives the fitting mechanism when the at least one light receiver is receiving the emitted light.

3 . The machining system according to claim 2 , wherein
the at least one light exit opening is disposed in a specific position on the housing, and the at least one light receiver is disposed in a specific position on the fitting device so that a central axis of the fixing member being supported by the fitting mechanism is at a desired angle to the housing when the at least one light receiver is receiving the emitted light.

4 . The machining system according to claim 1 , wherein
the fitting device further includes an intensity measurement section configured to measure an optical intensity of the emitted light when the emitted light is received by the at least one light receiver, and the drive controller drives the fitting mechanism when the optical intensity is within a specific intensity range.

5 . The machining system according to claim 1 , wherein
the fitting device further includes an angle measurement section configured to measure an angle of incidence of the emitted light when the emitted light is received by the at least one light receiver, and the drive controller drives the fitting mechanism when the angle of incidence is within a specific angle range.

6 . The machining system according to claim 1 , wherein
the fixing member is fitted in a through hole provided in the housing, the at least one light exit opening comprises a plurality of light exit openings corresponding to the through hole, the at least one light receiver comprises a plurality of light receivers in one-to-one correspondence with the plurality of light exit openings, and the drive controller controls driving of the fitting mechanism based on a result of light reception by each of the plurality of light receivers.

7 . The machining system according to claim 1 , wherein
the fitting device further includes a notification section configured to notify of information about, the result of light reception by the at least one light receiver.

8 . The machining system according to claim 1 , Wherein
the housing has a lens member disposed over the at least one light exit opening and configured to adjust directionality of the emitted light.

9 . A fitting device for fitting a fixing member in a housing of a target device, the target device having:
the housing;
a light source disposed within the housing; and
at least one light exit opening provided in the housing and configured to let out light emitted by the light source to an exterior of the housing as emitted light,
the fitting device comprising: a fitting mechanism configured to be driven to fit the fixing member in the housing; at least one light receiver configured to receive the emitted light that has exited through the at least one light exit opening; and a drive controller configured to control driving of the fitting mechanism based on a result of light reception by the at least one light receiver.

10 . The fitting device according to claim 9 , wherein
the drive controller drives the fitting mechanism when the at least one light receiver is receiving the emitted light.

11 . The fitting device according to claim 10 , wherein
the at least one light exit opening is disposed in a specific position on the housing, and the at least one light receiver is disposed in a specific position on the fitting device so that a central axis of the fixing member being supported by the fitting mechanism is at a desired angle to the housing when the at least one light receiver is receiving the emitted light.

12 . The fitting device according to claim 9 , further comprising
an intensity measurement section configured to measure an optical intensity of the emitted light when the emitted light is received by the at least one light receiver, wherein the drive controller drives the fitting mechanism when the optical intensity is within a specific intensity range.

13 . The fitting device according to claim 9 , further comprising
an angle measurement section configured to measure an angle of incidence of the emitted light when the emitted light is received by the at least one light receiver, wherein the drive controller drives the fitting mechanism when the angle of incidence is within a specific angle range.

14 . The fitting device according to claim 9 , wherein
the fixing member is fitted in a through hole provided in the housing, the at least one light exit opening comprises a plurality of light exit openings corresponding to the through hole, the at least one light receiver comprises a plurality of light receivers in one-to-one correspondence with the plurality of light exit openings, and the drive controller controls driving of the fitting mechanism based on a result f light reception by each of the plurality of light receivers.

15 . The fitting device according to claim 9 , further comprising
a notification section configured to notify of information about the result of light reception by the at least one light receiver.

16 . The fitting device according to claim 9 , wherein
the housing has a lens member disposed over the at least one light exit opening and configured to adjust directionality of the emitted light.

17 . A method for controlling a fitting device for fitting a fixing member housing of a target device,
