Traditional fiber-optic cutting methods mainly rely on sharp blades to break the optical fibers through mechanical pressure. However, this method has several problems, such as reduced cutting accuracy due to blade wear, possible damage to the optical fiber caused by improper operation, and contamination of the optical fiber end face by tiny fragments generated during the cutting process. Utility Model Content

[0013] Preferably, the air suction channel is located directly below the focusing lens and the laser generating module.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model controls the turning on of the laser generating module when the optical fiber and the optical fiber head section are kept clamped and fixed. When the laser generating module is turned on, it emits a laser beam of a specific wavelength and energy to heat the cutting part of the optical fiber, so that the optical fiber is heated to near its melting point without causing significant thermal damage. When the laser generating module is turned on to emit a laser beam of a specific wavelength and energy to heat the cutting part of the optical fiber, the laser beam emitted by the laser generating module will pass through the focusing lens. When the laser beam passes through the focusing lens, the laser beam will be accurately focused to a point on the surface of the optical fiber by the focusing lens for laser thermal cutting. When the optical fiber laser thermal cutting is completed, the suction fan is controlled to turn on. When the suction fan is turned on, the suction pipe and the suction channel will be used to suck and dissipate heat from the cutting part of the optical fiber, so that the suction airflow reduces the temperature of the optical fiber and prevents damage to the optical fiber caused by thermal stress, thereby achieving bladeless laser cutting of the optical fiber while ensuring the concentration of the energy of the laser beam emitted by the laser generating module and reducing the area affected by heat, so as to improve the optical fiber cutting accuracy.

[0016] 2. The utility model also drives the adjusting shaft to rotate through the knob. When the adjusting shaft rotates, it drives the secondary swing arm to swing. When the secondary swing arm swings, it drives the rear end of the connecting rod to swing back and forth. When the rear end of the connecting rod swings back and forth, it drives the limit slider to move back and forth along the inner wall of the limit straight slide groove. When the limit slider moves back and forth, it drives the supporting arm to move back and forth. When the supporting arm moves back and forth, it synchronously drives the upper mounting ring and the lower mounting ring to move back and forth. When the upper mounting ring and the lower mounting ring move back and forth synchronously, it drives the laser generating module and the focusing lens to move back and forth linearly, thereby realizing bladeless laser cutting of the optical fiber and facilitating the front and back linear movement adjustment of the cutting position of the laser generating module and the focusing lens.

A focusing lens 16 for focusing the laser beam is fixedly installed on the inner wall of the lower mounting ring 14, and the focusing lens 16 and the laser generating module 15 are kept on the same vertical line;

[0023] The main clamping platform 17 and the auxiliary clamping platform 18 are fixedly installed on both sides of the upper end of the cutting table 1. The outer sides of the upper ends of the main clamping platform 17 and the auxiliary clamping platform 18 are respectively hinged with a main clamping plate 19 and an auxiliary clamping plate 20 for clamping the required cut optical fiber. The lower ends of the main clamping plate 19 and the auxiliary clamping plate 20 are respectively bonded with clamping buffer pads.

[0024] Working principle: When in use, the utility model places the pre-treated and cleaned optical fiber on the upper end of the main clamping platform 17. When the optical fiber is placed on the upper end of the main clamping platform 17, the optical fiber head section is placed on the upper end of the auxiliary clamping platform 18. When the optical fiber head section is placed on the upper end of the auxiliary clamping platform 18, the main clamping plate 19 and the auxiliary clamping plate 20 are swung downward and closed. When the main clamping plate 19 and the auxiliary clamping plate 20 are swung downward and closed, the outer ends of the positioning protrusions 21 are respectively locked into The inner wall of the positioning notch 22, when the outer ends of the positioning protrusions 21 are respectively inserted into the inner wall of the positioning notch 22, the main clamping plate 19 and the auxiliary clamping plate 20 will maintain a lateral limit.

When the laser generating module 15 is turned on to emit a laser beam of a specific wavelength and energy to heat the cut part of the optical fiber, the laser beam emitted by the laser generating module 15 will pass through the focusing lens 16. When the laser beam passes through the focusing lens 16, the laser beam will be precisely focused to a point on the surface of the optical fiber through the focusing lens 16 for laser thermal cutting. When the optical fiber laser thermal cutting is completed, the suction fan 25 is turned on by control. When the suction fan 25 is turned on, the optical fiber cut part will be sucked and cooled through the suction pipe 24 and the suction channel 23, so that the suction airflow reduces the temperature of the optical fiber and prevents damage to the optical fiber caused by thermal stress, thereby realizing bladeless laser cutting of the optical fiber while ensuring the concentration of the laser beam energy emitted by the laser generating module 15 and reducing the area affected by heat, so as to improve the optical fiber cutting accuracy.

[0025] At the same time, before cutting the optical fiber, the fastening ring 7 is loosened by rotating. When the fastening ring 7 is loosened, the adjusting shaft 6 is driven to rotate by the knob. When the adjusting shaft 6 rotates, it will drive the secondary swing arm 8 to swing. When the secondary swing arm 8 swings, it will drive the rear end of the connecting rod 11 to swing back and forth. When the rear end of the connecting rod 11 swings back and forth, it will drive the limiting slider 10 to move back and forth along the inner wall of the limiting straight slide groove 9. When the limiting slider 10 moves back and forth, it will drive the supporting arm 12 to move back and forth. When the supporting arm 12 moves back and forth, it will synchronously drive the upper mounting ring 13 and the lower mounting ring 14 to move back and forth. When the upper mounting ring 13 and the lower mounting ring 14 move back and forth synchronously, it will drive the laser generating module 15 and the focusing lens 16 to adjust the front and back linear movement, thereby realizing bladeless laser cutting of the optical fiber while facilitating the front and back linear movement adjustment of the cutting position of the laser generating module 15 and the focusing lens 16.
