Optical fiber etching device

An optical fiber etching device, comprising:

• a base;
• a clamping assembly comprising two clamping members arranged on the base at intervals in a first direction, wherein the two clamping members each comprise a connecting seat arranged on the base, and a clamper movably connected with the connecting seat;
• the clamper has a clamping position and a releasing position;
• when the clamper is in the clamping position, a clamping space for clamping an optical fiber is formed between the clamper and the connecting seat;
• when the clamper is in the releasing position, the optical fiber is released;
• the connecting seat of each of the two clamping members is slidably connected with the base in the first direction, and the clamping space of each of the two clamping members extends in the first direction;
• and the clamping space of one of the two clamping members coincides with the clamping space of another one of the two clamping members in the first direction;
• two tensile force measuring members for measuring a tensile force applied to the optical fiber, wherein the two tensile force measuring members are each provided on the base and are each connected to the connecting seat of a corresponding one of the two clamping members;
• a torsional force measuring member comprising a torsional force sensor for measuring a torsional force applied to the optical fiber, wherein the torsional force sensor is provided on a side of the clamper facing toward the clamping space or a side of the connecting seat facing toward the clamping space;
• an etching assembly comprising a laser for generating laser light and a moving mechanism, wherein the moving mechanism is connected to the laser and configured for driving the laser to move so that the laser light etches the optical fiber along a length direction of the optical fiber;
• and
• a positioning member provided between the two clamping members of the clamping assembly, wherein the positioning member comprises a positioning groove extending in the first direction and extending through the positioning member, the positioning groove is configured for receiving the optical fiber, an inner surface of the positioning groove is configured for abutting against an outer peripheral surface of the optical fiber, one or more adsorption holes formed in the inner surface of the positioning groove, and the one or more adsorption holes are configured to be in communication with a suction member.
