Description

Technical Field

[0001] The invention belongs to the technical field of optical fiber and cable processing equipment, and in particular relates to an end surface ironing device for optical fiber and cable. Background Art

[0002] The existing Chinese patent database discloses a patent entitled "A Plastic Optical Fiber Hotming Machine," application number CN202410456518.X, filed April 16, 2024. The machine specifically relates to the technical field of optical fiber processing equipment and comprises a base, a shielding shell fixedly connected to the upper end of the base, a fiber feeding structure disposed at the front of the upper end of the base, a hotming structure disposed at the rear end of the upper end of the base, a spring-loaded flip-top box slidably connected to the rear left end of the base, a cleaning structure disposed at the front end of the hotming structure, and a detergent feeding structure fixedly connected to the shielding shell at the upper end of the cleaning structure. The plastic optical fiber hotming machine of the present invention pushes the fiber feeding structure inward so that the plastic optical fiber and the hotming structure are in a precisely aligned state, preventing the hotming structure from curling due to excessive pressure during the hotming process. After the hotming process is completed, the fiber feeding structure is pulled out to remove the plastic optical fiber, and the surface of the hotming structure is cleaned by the cleaning structure to remove plastic residue adhering to the surface of the hotming structure, thereby preventing it from affecting subsequent hotming operations.

The effect of end-face processing is closely related to the force applied to the optical fiber end face and the duration of the end-face processing. This proposal aims to propose an end-face processing device for optical fiber cables, which can effectively control the end-face processing time of the optical fiber and improve the quality of the end-face processing.

DETAILED DESCRIPTION

[0018] The technical solution of the present application is further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-4 The figure shows an end ironing device for an optical fiber cable, comprising a frame 1, a reducer 2 is provided at the bottom of the frame 1, and the output shaft section of the reducer 2 is connected to a first cam 3 and a second cam 4 at the front and rear. The head end of the arc section of the first cam 3 is convex, and the end end of the arc section of the first cam 3 is concave. The second cam 4 is mirror-imaged to the first cam 3.

A roller member 8 is fixed to the lower end of the ironing plate assembly 7. The outer peripheral surface of the roller member 8 abuts against the outer peripheral surfaces of the first cam 3 and the second cam 4.

[0020] Specifically, a positioning frame 9 is integrally provided on the upper surface of the workbench of the rack 1. The positioning frame 9 is provided with a through hole 10 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. The positioning bolts 14 are spaced apart and sleeved with pads 15. A compression spring 16 is sleeved on the positioning bolt 14 located between the two pads 15. The free end of the positioning bolt 14 is screwed with a positioning nut 17. The inner end surface of the positioning nut 17 is set against the surface of the outer pad 15. The two sets of limit blocks 12 on the positioning frame 9 clamp the optical fiber. At the same time, the compression spring 16 allows the limit blocks 12 to flexibly clamp the optical fiber, preventing 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, and a copper guide plate 21 is fixed to the inner wall of the sliding hole 20. A guide plate 22 is provided 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 the roller body 802 is sleeved on the pin.

[0024] Specifically, the ironing board assembly 7 includes a fixed block 701 slidably connected to the frame 1, a lower mold piece 702 is provided on the upper surface of the fixed block 701, an upper mold piece 703 is provided just above the lower mold piece 702, a working iron piece 704 is provided between the upper mold piece 703 and the lower mold piece 702, and also includes a plurality of mounting bolts 705, each mounting bolt 705 passes through the upper mold piece 703, the working iron piece 704 and the lower mold piece 702 in sequence, 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. 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 the through hole. A copper sleeve is provided in the fixed block 701, and a heating rod 708 is inserted into the copper sleeve. The upper end of the heating rod 708 passes through the lower mold sheet 702 and is connected to the working iron sheet 704, and the other end is connected to a heating wire 707, which is electrically connected to an external power supply.

[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. The two limit blocks 12 are elastically limited by the positioning bolts 14, positioning nuts 17 and compression springs 16 to avoid damage to the optical fiber during the clamping process. After completing the positioning and clamping of the optical fiber, 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.
