Description

Technical Field

[0001] The invention relates to a window opening and coating device, in particular to an optical fiber window opening and coating device. Background Art

[0002] The method of "opening a window" in the optical cable for communication is an emergency measure taken when encountering accidents such as broken cores during the laying of optical cables; window coating treatment is also required during the manufacturing process of fiber optic gratings. In the window opening, the traditional method is to manually hold a circular cutting knife to cut the two ends of the part that needs to be opened, so that the protective layer of the window opening part is disconnected, and then use a cutting knife to cut the part, thereby leaking the cable core part of the part.

[0003] This window opening method relies on the skills and experience of the operator, and it is difficult to ensure the consistency of the ring cutting and cutting force, which is easy to cause damage to the cable core and is extremely inconvenient to use; such as the patent with authorization announcement number CN218824830U, which discloses an outdoor optical fiber cable window opening tool, which belongs to the field of wire stripping tools. The window opening tool includes a gripping part, a cutter, an adjusting rod and a locking member: the gripping part has a first end and a second end, and the first end is located above the second end; the second end is provided with an arc-shaped space for placing the cable; the cutter moves closer to or away from the arc-shaped space and the first end; the adjusting rod longitudinally passes through the first end and is connected to the cutter; the locking member is arranged on the first end to lock and fix the adjusting rod on the first end. The window opening tool has a simple structure and is easy to use. It can effectively perform radial ring cutting and axial sectioning on the cable, and quickly complete the cable skylight opening work. At the same time, the cutting depth can be effectively controlled by the adjusting rod and the locking member to ensure that the cutting and cutting depths are consistent, avoid damage to the cable, and use it safely.

[0004] Although the above technology has many advantages, it still has defects when used: the length of the window is relatively fixed, the adaptability is poor, and the selection of the window position is inconvenient and cannot be dealt with according to the actual situation.
