[0033] like Figure 2 As shown, the reversing device 3 includes:

[0034] The panel 31 is used to receive the optical network terminal transported by the input conveyor belt 2.

[0035] A steering column 32, the top end of which is connected to the bottom of the face plate 31, and is used to drive the face plate 31 to rotate;

[0036] The driving motor 33 is connected to the steering column 32 and is used to drive the steering column 32 to rotate.

[0037] The reversing device 3 also includes a base 34, the steering column 32 and the base 34 are screwed together, and a limit portion 321 is provided on the steering column 32, and a first limit fitting portion 341 for limiting the clockwise rotation of the steering column 32 by 90 degrees and a second limit fitting portion 342 for limiting the counterclockwise rotation of the steering column 32 by 90 degrees are provided on the base 34.

When the side optical coupler 312 located in the middle detects an obstruction, and the side optical coupler 312 located at the opening has no obstruction, it indicates that there is an optical network terminal in the groove 311.
