The spring 323 is sleeved on the rod body 322 and its upper and lower ends are respectively abutted against the bottom end of the rod seat 321 and the upper end of the butt joint 324.

[0063] The mounting frame 1 includes a mounting surface, the floating pressure rod 32 and the connecting rod 21 are both perpendicular to the mounting surface of the mounting frame 1, the bottom end of the rod seat 321 has a step hole 3211, the upper end of the abutment head 324 has a receiving hole 324c, the upper end of the rod body 322 extends into the step hole 3211, the upper end of the spring 323 abuts against the step of the step hole 3211, the lower end of the rod body 322 and the lower end of the spring 323 respectively extend into the receiving hole 324c, and a spring mounting seat 325 is provided between the lower end of the spring 323 and the bottom wall of the receiving hole 324c.

[0064] Reference Figure 7As shown, the abutment head 324 includes a conical body 324a disposed at its bottom end, and a limiting groove 324b for accommodating the optical fiber is radially formed at the bottom end of the conical body 324a.

[0066] In some embodiments, the mounting frame 1 is also equipped with a laser rangefinder 700 and a visual positioning camera 800. The laser rangefinder 700 can measure the height of the water-cooling plate surface, thereby adjusting the distance from the floating pressure rod 32 to the water-cooling plate surface, and can achieve precise positioning during the optical fiber processing process, ensuring that the optical fiber can be completely pressed into the groove, and ensuring high-quality processing results. The visual positioning camera 800 can use a CCD camera, which can identify the MRAK point on the surface of the water-cooling plate.

[0067] When in use, first place the optical fiber reel 51 on the fiber release bracket 52 of the optical fiber release device 500. During the fiber guiding process, turn on the fiber release motor 53 to start releasing the optical fiber. At the same time, the guide assembly 22 of the fiber guiding device 600 will guide the optical fiber through the channel of the limiting cylinder 33. Then the optical fiber is axially pressed into the optical fiber groove by the floating pressure rod 32.
