A through hole 10 is provided on the positioning frame 9 for the optical fiber to pass through. Horizontal slide rails 11 are provided on the upper surface of the positioning frame 9 on both sides of the through hole 10. Each slide rail 11 is slidably connected to a limit block 12. A side plate 13 extends from the outer side of the limit block 12. A positioning bolt 14 is inserted between the corresponding side plates 13 of the two limit blocks 12. A pad 15 is sleeved on the positioning bolt 14 at intervals. A compression spring 16 is sleeved on the positioning bolt 14 located between the two pads 15. A positioning nut 17 is screwed on the free end of the positioning bolt 14. The inner end surface of the positioning nut 17 is set against the surface of the pad 15 on the outer side. The two groups of limit blocks 12 on the positioning frame 9 clamp the optical fiber. At the same time, the setting of the compression spring 16 makes the limit block 12 in a flexible clamping state for the optical fiber to avoid damage to the optical fiber during the clamping process.

[0021] Specifically, an L-shaped frame 18 is integrally provided on the upper surface of the frame 1 , and an infrared detection sensor 19 for detecting the height of the optical fiber end face is fixedly connected to the inner side of the vertical section of the L-shaped frame 18 .

[0022] Specifically, a sliding hole 20 is opened on the frame 1, a copper guide plate 21 is fixedly connected to the inner wall of the sliding hole 20, and a guide plate 22 is arranged on the outer side of the ironing plate assembly 7, and the guide plate 22 is slidably connected to the copper guide plate 21.

[0023] Specifically, the roller member 8 includes a connecting rod seat 801 fixedly connected to the lower end of the ironing board assembly 7, a pin is inserted into the free end of the connecting rod seat 801, and a roller body 802 is sleeved on the pin.

The working iron sheet 704 and the lower mold sheet 702 are connected to the fixed block 701, the upper mold sheet 703 is provided with a through hole, and a spherical groove 706 for end face processing of the plastic optical fiber is provided on the surface of the working iron sheet 704 opposite to the through hole. A copper sleeve is provided in the fixed block 701, and a heating rod 708 is inserted in the copper sleeve.

[0025] During operation, the operator first passes the optical fiber that needs end face processing through the through hole 10 on the positioning frame 9 until the end face of the optical fiber moves to the horizontal plane where the infrared detection sensor 19 is located, and then moves the limit blocks 12 on both sides so that the limit blocks 12 clamp the optical fiber, and elastically limits the two limit blocks 12 through the positioning bolts 14, positioning nuts 17 and compression springs 16, so as to avoid damage to the optical fiber during the clamping process. After the positioning and clamping of the optical fiber is completed, the reducer 2 is controlled to work so that the first cam 3 and the second cam 4 rotate synchronously at a low speed counterclockwise. When the first cam 3 and the second cam 4 rotate counterclockwise at a low speed, the first cam 3 and the second cam 4 rotate counterclockwise at a low speed. 4 moves to the roller member 8, the ironing plate assembly 7 is moved upward, so that the spherical groove 706 on the ironing plate assembly 7 contacts the end face of the optical fiber, thereby completing the ironing work. When the relative angle between the first cam 3 and the second cam 4 is 0°, the contact time between the ironing plate assembly 7 and the optical fiber is the shortest. The first cam 3 is rotated to make the first cam 3 and the second cam 4 rotate relative to each other, thereby increasing the arc length of the arc segment where the first cam 3 and the second cam 4 contact the roller member 8, thereby extending the contact time between the ironing plate assembly 7 and the optical fiber, and effectively improving the effect of optical fiber end face processing.
