[0074] Example 10

[0075] Embodiment 10 provides a method for removing a protective cap of an optical fiber coupler, using the above-mentioned device for removing a protective cap of an optical fiber coupler. The method for removing a protective cap of an optical fiber coupler comprises:

[0076] S1. The moving mechanism drives the connecting rod driving mechanism and the clamping mechanism to move, so that the clamping mechanism can extend from the inside of the shell.

[0077] S2. The connecting rod driving mechanism opens the clamping mechanism, and the clamping mechanism is aligned with the protective cap of the optical fiber coupler so that the protective cap of the optical fiber coupler is inside the clamping mechanism. Then the connecting rod driving mechanism closes the clamping mechanism to clamp the protective cap of the optical fiber coupler.

[0078] S3, the moving mechanism controls the clamping mechanism for clamping the protective cap of the optical fiber coupler to retract into the housing, and the connecting rod driving mechanism opens the clamping mechanism, and the protective cap of the optical fiber coupler falls into the storage mechanism.

[0079] In the extraction device of the fiber optic coupler protective cap, the rotating component 33 in the connecting rod driving mechanism 3 adopts a single-axis servo, and the driving component 46 in the moving mechanism 4 includes a stepping motor and a driver connected to the stepping motor. The driver and the single-axis servo are connected to the power mechanism 8. The control module 82 in the power mechanism 8 can control the single-axis servo and the driver to operate separately.

The sensor 5 measures the movement position of the slider 44 each time, and the control module 82 has recorded the movement position information of the slider 44 each time according to the length of the storage box 61 in the storage mechanism 6 and the length of the fiber optic coupler protective cap.

[0080] When extracting, first, the control module 82 controls the driver to make the moving mechanism 4 drive the first clamp 21 and the second clamp 22 to move out from the inside of the housing 1, and then the control module 82 controls the single-axis steering gear to open the first clamp 21 and the second clamp 22, and then controls the first clamp 21 and the second clamp 22 to close, and after clamping the protective cap of the optical fiber coupler, the control module 82 controls the driver to move the first clamp 21 and the second clamp 22 to the inside of the housing 1, and to the right side of the storage box 61, and then the control module 82 controls the first clamp 21 and the second clamp 22 to open so that the protective cap of the optical fiber coupler falls into the storage box 61. Since the control module 82 has recorded and stored the position of the slider 44 when the protective cap of the optical fiber coupler falls, when the sensor 5 detects that the slider 44 moves to a specific position during the clamping process, the control module 82 controls the single-axis steering gear to open the first clamp 21 and the second clamp 22. Among them, the control module 82 adopts a PLC (programmable logic controller).
