[0033] Specific working principle:

[0034] When using the FA optical fiber array end face detection device, first place the optical fiber array to be detected on the inner side of the fixed clamping groove 6 in the positioning groove 4, then turn the horn nut 21 to adjust the inner side of the positioning groove 4 through a threaded connection with the threaded screw 20, so that the movable clamping groove 7 is pushed to dock with the fixed clamping groove 6 by adjusting the threaded screw 20, so that the optical fiber array can be safely and stably clamped and positioned, and the optical fiber array can be protected by the rubber pad 22, and then the stepper motor 10 drives the drive shaft 19 to drive the first pulley 18 to rotate.

When the rotating drum 3 rotates, the limiting slide rail 23 rolls relatively between the outer sides of the stabilizing pulley 16 to support and limit the rotating drum 3 for stability. The detection result is displayed on the display screen 5 during the detection process. After the detection of a single optical fiber array is completed, the optical fiber array can be relatively pulled out by adjusting the detection seat 11 to move backward by adjusting the electric cylinder 12. At the same time, the stabilizing guide rod 9 moves back and forth in the stabilizing sleeve 15 to stabilize the detection seat 11. The detected optical fiber array is rotated and moved to the bottom of the rotating drum 3, the clevis nut 21 is loosened, the optical fiber array is removed, and then the optical fiber array to be detected is placed. This process is repeated to efficiently perform the end face detection operation of the optical fiber array.
