Description

Technical Field

[0001] The present invention relates to the technical field of fiber supply for fiber optic winding machines, and more particularly to a fiber supply mechanism for an automatic fiber optic winding machine. Background Art

[0002] With the development of society and technology, the performance of equipment in various fields has also been improved. Among them, the fiber optic gyroscope is the second-generation optical gyroscope and is widely used in fields such as aerospace, aviation, navigation, and weaponry, as well as the industrial field. The core sensitive element in the fiber optic gyroscope is the fiber optic loop, and the fiber optic loop is produced by winding with a winding machine.

[0003] Chinese Patent Publication No. CN217376783U discloses an automatic raw material feeding device for a fiber optic winding machine, including a base. A support plate is welded at the rear edge of the center position of the upper surface of the base. An adjusting component and a transmission component are respectively arranged at the top ends of the front and rear end faces of the support plate. By using the adjusting component and the telescopic component in the present utility model, when the motor B operates, the position of the fiber releasing roller on the surface of the rotating plate is adjusted, thereby adjusting the linear speed of the fiber released from the fiber releasing roller. When the motor C operates, the position of the connecting frame is adjusted to adjust the tension of the fiber. The above related technologies have the following defects: The fiber is generally wound into a disk. As the fiber is used, a new fiber disk needs to be replaced. However, the existing fiber supply structure needs to stop fiber supply after the fiber disk is used up, then replace the new fiber disk, and then manually pass the new fiber through the lead structure, and cannot automatically complete the feeding. Stopping the machine is required during feeding. Therefore, a fiber supply mechanism for an automatic fiber optic winding machine is proposed. Summary of the Invention

[0014] In summary, the present invention includes the following beneficial technical effects:

[0015] 1. By providing the front clamping plate, the rear clamping plate, the inner damping plate and the outer damping plate, when refueling is required, the power structure drives the front clamping plate and the rear clamping plate to move in front of a new fiber feeding structure on one side. The power structure controls the strip rod to move backward. The inner damping plate generates resistance to the movement of the front clamping plate by contacting the outer damping plate, so that the front clamping plate moves away from the rear clamping plate and separates. The fiber end on the new fiber optic disc droops. When the rear clamping plate moves backward, it moves behind the drooping fiber. The front clamping plate is located in front of the fiber end. When controlling the strip rod to move forward, the outer damping plate generates damping to the movement of the inner damping plate, so that the rear clamping plate first approaches the front clamping plate to clamp the drooping fiber end. Then, when controlling the strip rod to move forward, the clamped fiber is pulled out from the fiber optic disc by driving the front clamping plate and the rear clamping plate, so that the front clamping plate and the rear clamping plate move to the front end of the fiber feeding limiting structure. Then, the power structure controls the strip rod to move to one side of the fiber feeding limiting structure, driving the fiber to move between the fiber feeding limiting structures, and automatic feeding can be completed without stopping the machine.

[0016] 2. In the present invention, by providing a vertical rod, an inclined frame, a pressure telescopic rod and a corner block, when the inclined frame moves to the left, it first drives the vertical shaft and the strip rod to move forward. At the same time, the vertical shaft slides within the vertical frame. When the inclined frame pushes the vertical shaft to move to the front end of the bent frame, when the inclined frame continues to move to the left, it pulls the vertical shaft to move to the left. At the same time, the vertical shaft drives the vertical frame to move to the left. The vertical frame drives the vertical rod through the bent rod, the pressure telescopic rod and the corner block, driving the conveyor belt to rotate. When the front clamping plate and the rear clamping plate move to the left, it drives the conveyor belt at the rear to rotate synchronously. When pushing the optical fiber between two rows of fiber feeding wheels, it drives the corresponding fiber disk to move to the rear of the fiber feeding wheels, keeping the optical fiber released from the fiber wheel in a straight line.

[0017] 3. In the present invention, by providing a bent dialing plate, a force-bearing bent rod and a fiber feeding wheel, when the vertical frame moves to the left, it first drives the bent dialing plate to move to the left to contact the force-bearing bent rod, pushing the force-bearing bent rod to drive the side plate above to move upward, separating the two rows of fiber feeding wheels from each other, facilitating the movement of the optical fiber moving to the left between the two rows of fiber feeding wheels. When the inclined frame moves to the right, the upper end of the force-bearing bent rod moves from below the bent dialing plate, pushing the bent dialing plate to rotate. When the vertical frame moves to the right, the two rows of fiber feeding wheels will not move away from each other to loosen the clamping of the optical fiber. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0028] The following will Figures 1-9 further elaborate on the present invention in detail.

[0029] An embodiment of the present invention discloses a fiber feeding mechanism for an automatic fiber optic winding machine. As Figure 1 shown, it includes a support frame 1. Transmission wheels 2 are rotatably connected to the four corners of the support frame 1. The four transmission wheels 2 are driven by a conveyor belt 3. A plurality of fiber feeding structures 6 are installed on the outer ring surface of the conveyor belt 3.

[0030] The fiber feeding structure 6 includes a vertical rod 61 and a mounting shaft 62. One end of the vertical rod 61 away from the conveyor belt 3 is rotatably sleeved on the outer surface of the mounting shaft 62. The mounting shaft 62 is damping-connected to the vertical rod 61. A fiber optic disc 63 is detachably connected to the outer surface of the mounting shaft 62. The fiber optic disc 63 with the fiber used up can be removed from the mounting shaft 62, and then a new fiber optic disc 63 can be installed.

[0031] A fiber feeding limiting structure 7 is installed at the lower end of the support frame 1 and in front of the conveyor belt 3. A rear clamping plate 4 is arranged below the conveyor belt 3 and on the right side of the fiber feeding limiting structure 7. A front clamping plate 9 is arranged in front of the rear clamping plate 4. A strip rod 5 is fixed to the right end of the rear clamping plate 4. The right end of the front clamping plate 9 is slidably sleeved on the outer surface of the strip rod 5. A tension telescopic rod 10 is fixed to the bottom surface of the right end of the front clamping plate 9. The rear end of the tension telescopic rod 10 is fixed to the right end of the rear clamping plate 4. An inner damping plate 12 is fixed to the right end of the front clamping plate 9. An outer damping plate 11 is arranged in contact with the right side surface of the inner damping plate 12. The front end of the outer damping plate 11 is fixed to the support frame 1. When the strip rod 5 moves backward, the outer damping plate 11 generates resistance to the movement of the inner damping plate 12, pushing the rear clamping plate 4 to gradually move away from the front clamping plate 9, stretching the tension telescopic rod 10. Then when the strip rod 5 moves forward, the outer damping plate 11 applies resistance to the inner damping plate 12, causing the front clamping plate 9 to first approach the rear clamping plate 4 to clamp the optical fiber therebetween. Then when the strip rod 5 continues to move forward, the front clamping plate 9 and the rear clamping plate 4 drive the optical fiber to move forward synchronously to pull the optical fiber out of the optical fiber reel 63. A power structure 8 is installed at the front end of the strip rod 5, and the power structure 8 is connected to the support frame 1.

[0032] The power structure 8 includes a power telescopic rod 801, a bending frame 802 and an inclined frame 803. The fixed end of the power telescopic rod 801 is fixed to the support frame 1, and the telescopic end of the power telescopic rod 801 is fixed to the inclined frame 803. The inclined frame 803 is located above the bending frame 802. The bending frame 802 is fixed to the support frame 1. A vertical shaft 804 is fixed to the upper surface of the front end of the strip rod 5. Both the inclined frame 803 and the bending frame 802 are slidably sleeved on the outer surface of the vertical shaft 804. The inclined frame 803 bends away from the support frame 1, and the front end of the bending frame 802 bends horizontally to the left at a right angle. A longitudinal rod 611 is fixed to the front surface of the vertical rod 61. The vertical rod 61 is perpendicular to the outer ring surface of the conveyor belt 3, and the vertical rod 61 is perpendicular to the longitudinal rod 611. The longitudinal rod 611 is parallel to the axis of the transmission wheel 2. A longitudinal frame 807 is arranged above the inclined frame 803. The longitudinal frame 807 is slidably sleeved on the outer surface of the vertical shaft 804. A horizontal telescopic rod 808 is fixed to the left side surface of the longitudinal frame 807. The other end of the horizontal telescopic rod 808 is fixed to the support frame 1. The horizontal telescopic rod 808 ensures that the longitudinal frame 807 can only move horizontally. When the inclined frame 803 starts to move to the left, the vertical shaft 804 moves in the inclined frame 803 and first slides forward at the longitudinal end of the bending frame 802, driving the strip rod 5 to move forward. When the vertical shaft 804 moves to the front end of the bending frame 802, when the inclined frame 803 continues to move, it pushes the vertical shaft 804 to move to the left at the front end of the bending frame 802. At the same time, the vertical shaft 804 drives the longitudinal frame 807 to move to the left. A bending rod 809 is fixed to the upper surface of the rear end of the longitudinal frame 807. The upper end of the bending rod 809 bends backward. A pressure telescopic rod 810 is fixed to the rear end of the bending rod 809. A corner block 811 is fixed to the rear end of the pressure telescopic rod 810. The corner block 811 is a right triangle. The left side surface of the corner block 811 is a longitudinal surface, and the right side surface of the corner block 811 is an inclined surface. The rear end of the corner block 811 is located behind the front end of the longitudinal rod 611. When the longitudinal frame 807 moves to the left, it drives the corner block 811 to move to the left through the bending rod 809 and the pressure telescopic rod 810. The corner block 811 pushes the adjacent vertical rod 61 on the left to drive the corresponding optical fiber disk 63 to move to the left.

[0033] A longitudinal track rod 805 is fixed to the front end of the strip rod 5. A transverse track frame 806 is slidably sleeved on the front end of the longitudinal track rod 805. The support frame 1 is slidably sleeved on the left end of the transverse track frame 806. The longitudinal track rod 805 and the transverse track frame 806 limit the movement tracks of the vertical shaft 804 and the strip rod 5.

[0034] The fiber feeding limit structure 7 includes two side plates 701. A row of longitudinally distributed fiber feeding wheels 702 are inserted into the right side surfaces of the two side plates 701. Guide wire inlet plates 709 are fixed to the mutually remote sides of the two side plates 701. The ends of the two guide wire inlet plates 709 on the right side of the fiber feeding wheels 702 approach each other, bend, and then move away from each other. The right ends of the two guide wire inlet plates 709 are distributed in a V shape. The right end of the fiber feeding wheel 702 is a conical surface. When the optical fiber moves to the left, it is convenient to move the optical fiber between the two rows of fiber feeding wheels 702 through the space between the two guide wire inlet plates 709.

[0035] A force-bearing bent rod 710 is fixed to the upper surface of the upper guide wire inlet plate 709 among the two guide wire inlet plates 709. The upper end of the force-bearing bent rod 710 bends forward. A bent deflecting plate 711 is elastically rotatably connected to the back surface of the longitudinal frame 807. The bent deflecting plate 711 is inclined to the right and then horizontally bent to the right. The bottom surface of the horizontal end of the bent deflecting plate 711 is above the upper surface of the force-bearing bent rod 710. The bottom surface of the inclined end of the bent deflecting plate 711 is below the bent end of the force-bearing bent rod 710. When the longitudinal frame 807 moves to the left, it drives the bent deflecting plate 711 to push the force-bearing bent rod 710 upward, driving the two rows of fiber feeding wheels 702 to move away from each other, facilitating the entry of the optical fiber between the two rows of fiber feeding wheels 702. Then, the bent deflecting plate 711 moves to the left side of the force-bearing bent rod 710, causing the two rows of fiber feeding wheels 702 to clamp the optical fiber. Then, when the bent deflecting plate 711 follows the longitudinal frame 807 and moves to the right, the force-bearing bent rod 710 pushes the bent deflecting plate 711 to rotate, causing the bent deflecting plate 711 to move to the right side of the force-bearing bent rod 710.

[0036] A central gear 704 is elastically rotatably penetrated through the right side surface at the lower end of the support frame 1. Side gear plates 703 are engaged with both the front and rear sides of the central gear 704. Two vertical rods 705 are fixed to the upper surface of the support frame 1. Each side plate 701 is slidably sleeved on the outer surfaces of the two vertical rods 705. The two ends of the two side gear plates 703 engaged with the same central gear 704 are respectively fixed to the two side plates 701. Worms 706 are fixed to the left ends of the upper row of fiber feeding wheels 702. A worm gear 707 is rotatably sleeved on the left side surface of the upper side plate 701 among the two side plates 701. The worm 706 is engaged with the worm gear 707. A motor 708 is fixed to the left side surface of the upper side plate 701 among the two side plates 701. The rear end of the worm gear 707 is fixed to the output end of the motor 708. When the upper side plate 701 moves, through the engagement of the side gear plate 703 and the central gear 704, the two side plates 701 move away from each other synchronously.

[0037] Parallel plates 13 are fixed to the bottom surfaces of the front clamping plate 9 and the rear clamping plate 4. The surfaces of the front clamping plate 9 and the rear clamping plate 4 that face each other are flush with the surfaces of the two parallel plates 13 that face each other. The two parallel plates 13 are located below the strip rod 5. The surfaces of the right ends of the two parallel plates 13 that face each other are inclined surfaces. A one-way dial 14 is arranged below the bending frame 802. The right side surface of the lower end of the one-way dial 14 is elastically rotatably connected to the support frame 1. The one-way dial 14 can only elastically rotate in one direction to the left. The one-way dial 14 is located in front of the side plate 701, the fiber feeding wheel 702, and the guiding wire inlet plate 709. The one-way dial 14 and the inclined surfaces of the parallel plates 13 are at the same height. When the front clamping plate 9 and the rear clamping plate 4 move to the front of the two rows of fiber feeding wheels 702, the one-way dial 14 moves to the right side of the two parallel plates 13 by rotation. When the two parallel plates 13 move to the right following the front clamping plate 9 and the rear clamping plate 4, the one-way dial 14 can push the two parallel plates 13 away from each other by contacting the inclined surfaces of the right ends of the two parallel plates 13, so that the front clamping plate 9 and the rear clamping plate 4 move away from each other to release the clamping of the optical fiber, preventing the optical fiber from being pulled out between the two rows of fiber feeding wheels 702.

[0038] The working principle is as follows: When feeding the optical fiber, the motor 708 drives the worm 707 to rotate and mesh with the worm wheel 706. The upper fiber feeding wheel 702 rotates actively, feeding the optical fiber forward between the upper and lower rows of fiber feeding wheels 702, pulling the optical fiber out from the fiber reel 63. At the same time, a new fiber reel 63 can be detachably installed on the surface of the remaining mounting shafts 62. The outer end of the optical fiber on the surface of the fiber reel 63 located below the conveyor belt 3 droops under gravity. When the inclined frame 803 moves to the right and pushes the bar 5 backward through the vertical shaft 804, the inner damping plate 12 generates resistance to the movement of the front clamping plate 9 by contacting the outer damping plate 11, causing the front clamping plate 9 to move away from the rear clamping plate 4 and separate. When the bar 5 continues to move, it first pushes the rear clamping plate 4 to move and misalign with the lower end of the optical fiber to the rear of the optical fiber, so that the optical fiber is located between the front clamping plate 9 and the rear clamping plate 4. After the optical fiber on the surface of the fiber reel 63 directly behind the two rows of fiber feeding wheels 702 is used up, the power telescopic rod 801 is controlled to pull the inclined frame 803 to move to the left. The vertical shaft 804 moves in the inclined frame 803, first slides forward at the longitudinal end of the bent frame 802, driving the bar 5 to move forward. The outer damping plate 11 generates damping to the movement of the inner damping plate 12, causing the rear clamping plate 4 to first approach the front clamping plate 9 to clamp the drooping end of the optical fiber. Then, when controlling the bar 5 to move forward, the clamped optical fiber is pulled out from the fiber reel 63 through the front clamping plate 9 and the rear clamping plate 4, causing the front clamping plate 9 and the rear clamping plate 4 to move to the front of the side plate 701 and the fiber feeding wheels 702. Then, when the inclined frame 803 continues to move to the left, it pushes the vertical shaft 804 to move to the left at the front end of the bent frame 802. At the same time, the vertical shaft 804 drives the longitudinal frame 807 to move to the left. The longitudinal frame 807 drives the conveyor belt 3 to rotate through the bent rod 809, the pressure telescopic rod 810, and the angle block 811 to drive the longitudinal rod 611, so that when the front clamping plate 9 and the rear clamping plate 4 move to the left, the conveyor belt 3 behind is driven to rotate synchronously. When pushing the optical fiber into the space between the two rows of fiber feeding wheels 702, the corresponding fiber reel 63 is driven to move to the rear of the fiber feeding wheels 702. At the same time, when the vertical shaft 804 moves to the left, the upper end of the force-bearing bent rod 710 is pushed through the bent dial 711, pushing the two rows of fiber feeding wheels 702 away from each other, first pulling the optical fiber into the space between the two rows of fiber feeding wheels 702, and then the power telescopic rod 801 controls the inclined frame 803 to reset to the right.

[0039] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
