Description

Technical Field

[0001] The utility model relates to the field of rotating optical fiber devices, in particular to a rotating optical fiber device which can rotate 360 ​​degrees in a circular manner. Background Art

[0002] There are two main types of existing optical fiber rotation mechanisms. One is to use a set of gears with the same number of teeth to drive the optical fiber clamp, and open a small groove on the gear connected to the optical fiber clamp for taking and placing the optical fiber, so that the optical fiber can rotate along the central axis of the gear. Although the optical fiber rotation accuracy of this scheme is high and can rotate 360°, the disadvantage is that the optical fiber opening is small, it is inconvenient to take and place, and the optical fiber is easy to damage.

[0003] The second method is to use a worm gear to drive the optical fiber clamp. The optical fiber clamp is connected to the worm wheel. A groove is cut in the worm wheel for picking up and placing the optical fiber. It can rotate infinitely, but the opening is small, and it is also difficult to pick up and place the optical fiber. The worm gear is easy to wear, easy to produce metal dust, large backlash, low rotation accuracy, and cannot be used in occasions with high precision requirements. Utility Model Content
