[0002] Fiber lasers are lasers that use rare earth-doped glass optical fiber as the gain medium. They are widely used in laser fiber communications, industrial manufacturing, medical instruments and equipment, military defense security and other fields because of their advantages such as good beam quality, compact structure, low thermal efficiency and high power density.

[0003] At present, medium and high power fiber lasers usually use water cooling to dissipate heat. In the existing fiber laser cooling system, the optical fiber needs to be coiled in the optical fiber groove on the water cooling plate, and the heat generated by the optical fiber is transferred to the water cooling plate through heat conduction, and then the heat is taken away by the cooling water circulation.

[0004] In the prior art, when winding an optical fiber, the optical fiber is released from the optical fiber reel and then wound into an optical fiber groove. The optical fiber is easily damaged during the process of being pressed into the optical fiber groove, which affects the winding quality. Summary of the invention

[0005] To this end, the utility model provides an optical fiber winding and pressing mechanism, which solves the problem that the optical fiber is easily damaged during the process of winding into the optical fiber groove, affecting the winding quality.

[0010] In one embodiment of the present invention, the abutment head includes a cone at the bottom end thereof, and a limiting groove for accommodating the optical fiber is radially formed at the bottom end of the cone.

[0011] In an embodiment of the present utility model, the rod seat is in a columnar shape, the frame body is provided with a height adjustment hole, and the rod seat is provided with a height adjustment groove corresponding to the height adjustment hole.

[0012] In an embodiment of the present utility model, an adjustment component is provided between the limiting cylinder and the frame body to adjust the position of the limiting cylinder along the axial direction of the limiting cylinder.

[0013] In one embodiment of the utility model, the side end of the frame body has a first mounting bevel, and the adjustment component includes a fixed block installed on the first mounting bevel, the fixed block is provided with an adjustment groove in a direction parallel to the first mounting bevel, an adjustment slider is slidably arranged in the adjustment groove, the adjustment slider has a second mounting bevel parallel to the first mounting bevel, the limiting cylinder is connected to a bracket installed on the second mounting bevel, and the axis of the limiting cylinder is parallel to the first mounting bevel.

After the optical fiber passes through the channel of the limiting cylinder, it radially passes through the lower end of the floating pressure rod. The limiting cylinder is inclined to the floating pressure rod, which reduces the stress and curvature of the optical fiber and enables the optical fiber to be pressed into the optical fiber groove through the lower end of the floating pressure rod with a smaller curvature.

The spring 23 is sleeved on the rod body 22 and its upper and lower ends are respectively butted against the lower end of the rod seat 21 and the upper end of the butt joint 24.

[0037] The limiting cylinder 3 is arranged obliquely to the floating pressure rod 2, and the limiting cylinder 3 has an axial channel for the optical fiber to pass through.

[0038] Through the above arrangement, after the optical fiber passes through the channel of the limiting cylinder 3, it radially passes through the lower end of the floating pressure rod 2. The limiting cylinder 3 is arranged obliquely to the floating pressure rod 2, which reduces the stress and curvature of the optical fiber and enables the optical fiber to be pressed into the required optical fiber groove through the lower end of the floating pressure rod 2 with a smaller curvature. Through the floating of the floating pressure rod 2, the optical fiber is prevented from being damaged by excessive pressure during the fiber pressing process, and a floating effect can be provided when it abuts against the optical fiber, which plays a buffering role during winding and protects the optical fiber from damage.

[0041] In some embodiments, reference Figure 4 As shown, the rod seat 21 is in a columnar shape, the frame body 1 is provided with a height adjustment hole 11, and the rod seat 21 is provided with a height adjustment groove 21a corresponding to the height adjustment hole 11, so as to facilitate the adjustment of the height position of the rod seat 21.

The locking block 45 and the adjusting slider 42 can contact each other through an inclined surface, and the locking handle 44 and the fixing block 41 can be connected through threads. When the locking handle 44 is rotated, the locking block 45 can move relative to the adjusting slider 42 to limit the sliding of the adjusting slider 42 after contacting the adjusting slider 42.

[0045] Through the above arrangement, the relative positions of the floating pressure rod 2 and the limiting cylinder 3 can be conveniently adjusted while the angle between the axes of the two is kept unchanged.

[0046] In some embodiments, reference Figure 5 As shown, the limiting cylinder 3 includes a hollow cylindrical body 31 and a hollow conical body 32 extending from the hollow cylindrical body 31 and contracting in a direction away from the hollow cylindrical body 31 .

[0047] When in use, after the optical fiber is released from the fiber release tray, it passes through the channel of the limiting cylinder 3 and radially passes through the lower end of the floating pressure rod 2, and is abutted by the floating pressure rod 2 and pressed into the optical fiber groove on the water cooling plate.
