Description

Technical Field

[0001] The invention relates to the technical field of optical fiber winding machines, and in particular to an optical fiber winding machine. Background Art

[0002] The fiber ring is the sensing core of the fiber optic gyroscope. The basic requirements for it are a large extinction ratio and good reciprocity. How to wind a high-quality fiber ring is very important for the development of a fiber optic gyroscope. There are many winding methods. The quadrupole symmetrical winding method has the best effect and is an internationally used method. Due to the principle of the quadrupole symmetrical winding method, the fiber is wound from the midpoint, and half of the length of the fiber on the left and right sides is named A pole and B pole. The A pole and the B pole are wound on the A fiber supply wheel and the B fiber supply wheel respectively. When winding the A pole, the viewing point of the CCD camera is on the outside of the product wheel, and the CCD camera is easy to see. When winding the B pole, the viewing point of the CCD camera is on the inside of the product wheel (opposite to the A pole), and the CCD camera is blocked by the fiber release mechanism and the fiber routing mechanism of the fiber winding machine and cannot be seen. The existing practice is that the CCD camera is fixed and does not move. When winding the B pole, the A pole winding point is still observed. The winding conditions of half a turn of optical fiber and the B pole winding point cannot be observed, and the latest winding conditions of the B pole cannot be directly judged. When a winding problem is found, at least half a turn of optical fiber needs to be withdrawn, and the production efficiency is extremely low. Another method is to adjust the position of the CCD camera when winding the B pole. Due to the large magnification of the CCD camera, it is difficult to find a suitable observation position, so the position adjustment of the CCD camera is very cumbersome. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and cannot be understood as limitations on the present invention.

[0039] like Figure 1-Figure 5As shown, an optical fiber winding machine according to an embodiment of the present invention comprises an A fiber supply wheel 1, a B fiber supply wheel 2 and a skeleton 3. The optical fiber is wound from one end and wound on the A fiber supply wheel 1, and the optical fiber is wound from the other end and wound on the B fiber supply wheel 2. The connecting section of the optical fiber between the A fiber supply wheel 1 and the B fiber supply wheel 2 is wound on the skeleton 3. The optical fiber winding machine also comprises a base 4, a fiber releasing mechanism 40, a fiber walking mechanism 41, a CCD camera 42 and a fiber winding mechanism 8. The fiber releasing mechanism 40 is arranged on the base 4 for releasing the fiber from the A fiber supply wheel 1 or the B fiber supply wheel 2; the fiber walking mechanism 41 is arranged on the base 4 for transferring the optical fiber released by the A fiber supply wheel 1 or the B fiber supply wheel 2 to the skeleton 3 for winding; the CCD camera 42 is provided for the optical fiber winding mechanism 8. The camera 42 is fixedly arranged above the skeleton 3 to monitor whether the optical fiber wound on the skeleton 3 is neat; the fiber winding mechanism 8 includes a driving motor and a main shaft 81 coaxially fixedly connected to the driving motor, the skeleton 3 is sleeved at the center of the main shaft 81, and the fiber supply wheel A 1 and the fiber supply wheel B 2 are detachably arranged on the main shaft 81 and symmetrically distributed on both sides of the skeleton 3; wherein, a connecting sleeve 80 is arranged on the output shaft of the driving motor, the main shaft 81 has a first end 810 and a second end 811, the first end 810 and the second end 811 can be detachably connected to the connecting sleeve 80, and the fiber supply wheel A 1 is arranged close to the second end 811, and the fiber supply wheel B 2 is arranged close to the first end 810. Reference Figure 1 When the A fiber supply wheel 1 is releasing the fiber, the first end 810 is fixedly connected to the connecting sleeve 80. The user removes the A fiber supply wheel 1 from the main shaft 81 and installs it on the fiber release mechanism 40 to release the fiber. The B fiber supply wheel 2 moves synchronously with the main shaft 81 and remains relatively still with the skeleton 3. At this time, the CCD camera 42 can monitor in real time whether the optical fiber wound on the skeleton 3 is neat. Figure 2 When the B fiber supply wheel 2 is releasing the fiber, the second end 811 is fixedly connected to the connecting sleeve 80. The user removes the B fiber supply wheel 2 from the main shaft 81 and installs it on the fiber release mechanism 40 to release the fiber. The A fiber supply wheel 1 moves synchronously with the main shaft 81 and remains relatively still with the skeleton 3. At this time, the CCD camera 42 can monitor in real time whether the optical fiber wound on the skeleton 3 is neat. In this embodiment, it is only necessary to reverse the direction of the main shaft 81, so that the CCD camera can monitor the A-pole fiber winding and the B-pole fiber winding at the same time without adjusting the position of the CCD camera, and the operation is simple.

[0040] like Figure 3 As shown, a mounting hole 800 is provided at one end of the connecting sleeve 80 away from the motor. When the A fiber supply wheel 1 is releasing fiber, the first end 810 of the main shaft 81 is fixed in the mounting hole 800 by the positioning pin 5; when the B fiber supply wheel 2 is releasing fiber, the second end 811 of the main shaft 81 is fixed in the mounting hole 800 by the positioning pin 5.

[0041] Specifically, a first through hole 801 is formed on the outer circumferential surface of the connecting sleeve 80, a second through hole 812 is formed on the first end 810 of the main shaft 81, and a third through hole 813 is formed on the second end 811 of the main shaft 81. When the A fiber supply wheel 1 is releasing fiber, the positioning pin 5 passes through the first through hole 801 and the second through hole 812 at the same time; when the B fiber supply wheel 2 is releasing fiber, the positioning pin 5 passes through the first through hole 801 and the third through hole 813 at the same time.

[0042] like Figure 4 As shown, in this embodiment, the main shaft 81 includes a fixed shaft 82 and a pair of connecting shafts 83, the frame 3 is sleeved on the fixed shaft 82, and the two ends of the fixed shaft 82 are detachably connected to the pair of connecting shafts 83 respectively. The pair of connecting shafts 83 are symmetrically arranged about the frame 3, and the end of one of the connecting shafts 83 away from the frame 3 is the first end 810, and the end of the other connecting shaft 83 away from the frame 3 is the second end 811. When the frame 3 needs to be replaced, we can first remove the fixed shaft 82 from the pair of connecting shafts 83, then replace the frame 3 on the fixed shaft 82, and then install the fixed shaft 82 in the middle of the pair of connecting shafts 83. Since the structure of the pair of connecting shafts 83 is completely the same, the fixed shaft 82 can ensure that the frame 3 is in the middle of the pair of connecting shafts 83, that is, in the middle of the entire main shaft 81. Compared with the traditional main shaft that cannot be disassembled and needs to use a ruler to determine the middle position of the frame 3 in the main shaft 81, the structure of the present invention is simpler, does not need to use a ruler tool, and has high installation accuracy.

[0043] Specifically, a long slot 830 is formed on the connecting shaft 83, and the two ends of the fixed shaft 82 are respectively received in the long slots 830 of a pair of connecting shafts 83, and an open slot 831 is formed on the circumferential surface of the connecting shaft 83. The knob press head 6 passes through the open slot 831 and is threadedly connected to the fixed shaft 82 to fix the fixed shaft 82 to the connecting shaft 83. The installation is that the directions of the open slots 831 of the pair of connecting shafts 83 are opposite, so that the connection between the fixed shaft 82 and the connecting shaft 83 is more stable.

[0044] The main shaft 81 also includes a pair of sleeves 84, which are sleeved on the fixed shaft 82. One end of one of the sleeves 84 abuts against one side of the frame 3, and the other end abuts against one of the connecting shafts 83; one end of the other sleeve 84 abuts against the other side of the frame 3, and the other end abuts against the other connecting shaft 83 of the pair of connecting shafts 83. The purpose of setting the sleeves 84 is to prevent the side of the frame 3 from directly contacting the connecting shaft 83. In addition, the structures of the pair of sleeves 84 must be completely identical to ensure that the frame 3 is in the middle of the main shaft 81.

[0045] like Figure 5As shown, in order to ensure the balance of the main shaft 81, the optical fiber winding machine also includes a push rod mechanism 7 fixed on the base 4. When the A fiber supply wheel 1 is releasing the fiber, the end face of the second end 811 abuts against the push rod mechanism 7; when the B fiber supply wheel 2 is releasing the fiber, the end face of the first end 810 abuts against the push rod mechanism 7.

[0046] Specifically, the push rod mechanism 7 includes a support frame 70 fixed on the base 4 and a screw 71 threadedly connected to the support frame 70, and a rotating disk 72 is provided at one end of the screw 71; when the A fiber supply wheel 1 is releasing fiber, the end face of the second end 811 abuts against the other end of the screw 71; when the B fiber supply wheel 2 is releasing fiber, the end face of the first end 810 abuts against the other end of the screw 71.

[0047] Specifically, the other end of the screw 71 is disposed on the circular convex portion 710, and the end surfaces of the first end 810 and the second end 811 are both provided with a circular concave portion 814 that matches the circular convex portion 710. When the main shaft 81 rotates, the circular concave portion 814 rotates relative to the circular convex portion 710.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
