Description
Technical Field
[0001] The present invention belongs to the technical field of optical fiber surround system, and in particular relates to an intelligent control system and method for optical fiber surround system. Background Art
[0002] Fiber optic gyroscope is a high-precision inertial sensor used to measure attitude and orientation, and the fiber optic ring is the core sensing component of the fiber optic gyroscope. The fiber optic ring is a fiber optic sensitive element made by winding a section of optical fiber through special winding methods such as quadrupole symmetry, octupole symmetry, and hexadecanoe symmetry. The fiber length of fiber optic rings of different specifications ranges from hundreds of meters to several kilometers, and the time required to wind the fiber optic ring is generally several hours to more than ten hours.
[0003] The production process of optical fiber rings involves a variety of processes, such as the base laying process, in which several layers of base special optical fiber are pre-wound on the surface of the optical fiber ring skeleton using the cylindrical winding method to protect the inner circumference of the optical fiber ring; or after the optical fiber ring is completed, several layers of special optical fiber are wound on its outer surface to protect the outer circumference of the optical fiber ring; for example, the reel replacement process, in which the two ends of the optical fiber are respectively wound on two fiber release reels. In the process of winding the optical fiber ring from the midpoint of the optical fiber length, the fiber release reels required for different layers may be different, and it is necessary to switch to the fiber release reel required for the current layer according to the process; for example, the pole changing process requires that the optical fiber ring is not limited to one symmetrical winding method, but has a combination of two or more of cylindrical winding, quadrupole symmetry, octupole symmetry, and hexadecanopole symmetry to achieve the special performance of the optical fiber ring.
[0004] At present, the industry mainly uses semi-automatic equipment for ring winding, and the ring winding process requires manual observation and intervention. Due to the small diameter, transparency and high speed of the optical fiber, it is difficult to distinguish the arrangement of the optical fiber directly with the naked eye. Generally, a high-power camera is required to observe the arrangement of the optical fiber through the display screen. In addition, the optical fiber is fragile and easy to be damaged and broken. The production time of the optical fiber ring is long and the fault tolerance rate is low. The environmental temperature and humidity, air cleanliness, and optical fiber tension are extremely high. Therefore, it is required to control it very finely, continuously, smoothly, and reliably. The use of semi-automatic equipment for ring winding is a great test for the operator's physical strength and attention. A qualified ring winding operator needs several months of training to meet the ability requirements.
[0005] Fully automatic fiber optic ring winding is an effective way to improve the performance and production efficiency of fiber optic rings. At present, there are some fully automatic ring winding technologies at home and abroad, most of which only realize automatic fiber collection and release, and the reel changing process still needs manual operation; there are also a small number of technologies that realize automatic reel changing, but they do not have variable pole winding, tension detection, length detection, image recognition technology, digital technology, etc., and the degree of automation is not high enough.

[0014] The fiber optic ring winding control system is used to wind the optical fiber onto the fiber optic ring skeleton, and feedback data such as the optical fiber tension, winding length, winding turns, and winding speed during the winding process to the main control system. The fiber optic ring winding control system includes a head A, a head B, and a fiber optic ring skeleton. Tension sensors, length measuring encoders, gluing devices, fiber unwinding discs, and fiber guiding wheel mechanisms are arranged on both head A and head B.

[0025] A B guide wheel frame mechanism inner shaft is provided on the B outer shaft mechanism; the B guide wheel frame mechanism inner shaft is used to install the skeleton.
[0026] A method for using an intelligent control system for optical fiber winding. The reel changing movement is performed through the machine table movement control system, and the control process is as follows:
[0027] Step 1, the lifting turntable rises to clamp the optical fiber ring skeleton, and then the motor drives the BY slide table to move the B head to the right and away from the optical fiber ring skeleton;
[0028] Step 2, the machine table movement control system performs multi-axis linkage to move the A head originally at the upper fiber pay-off position to the left fiber take-up position, and move the B head originally at the right fiber take-up position to the lower fiber pay-off position;
[0029] Step 3: The AY slide table moves the A head to the right to suck and hold the optical fiber ring skeleton, and then the lifting turntable descends to release the optical fiber ring skeleton, completing the disk change.
[0030] During the disk change movement, the fiber spools on the A head and the B head will adaptively rotate through the PID control algorithm of the main control system to ensure that the optical fibers connecting the A head and the B head to the optical fiber ring skeleton always maintain a constant tension, preventing optical fiber damage and optical fiber ring loosening.
[0031] Preferably, when winding two layers of base fibers using the base winding method, the process is as follows:
[0032] The main control system automatically moves the A head and the B head to the upper fiber operation position ( Figure 9 position of step ①). The operator sets the A fiber spool on the A outer shaft mechanism of the A head, sets the B fiber spool on the B outer shaft mechanism of the B head, and positions and adsorbs the optical fiber ring skeleton on the inner axial end face of the B guide wheel frame mechanism of the B head.
[0033] There is a sufficient amount of base optical fiber on the A fiber spool, and the B fiber spool is an empty spool. The optical fiber of the A fiber spool is introduced into the optical fiber ring skeleton through the inner shaft of the A guide wheel frame mechanism, then into the inner shaft of the B guide wheel frame mechanism, and finally into the B fiber spool and fixed on the B fiber spool with tape.
[0034] The operating equipment continues to run. The main control system automatically moves the A head and the B head to the first layer winding position. During the running process, the fiber spools on the A head and the B head will adaptively rotate through the PID control algorithm of the main control system to ensure that the optical fibers connecting the A head and the B head to the optical fiber ring skeleton always maintain a constant tension, preventing optical fiber damage.
[0035] Then the winding movement starts. The B outer shaft mechanism and the inner shaft of the B guide wheel frame mechanism drive the optical fiber ring skeleton to rotate synchronously to wind the fiber. The inner shaft of the A guide wheel frame mechanism does not move. The A fiber spool rotates under the drive of the A outer shaft mechanism and releases the optical fiber onto the optical fiber ring skeleton.
[0036] During the fiber winding process, the fiber tension is detected in real time through a tension sensor, and the fiber winding and releasing speeds are automatically configured through the PID control algorithm of the main control system to keep the optical fiber under a constant tension at all times; the fiber winding length can be obtained through a length measuring encoder.
[0037] The first turn of the first layer of optical fiber is close to the right edge of the optical fiber ring skeleton, and then spirally arranged tightly to the left of the optical fiber ring skeleton. During the fiber winding process, every time one turn of optical fiber is wound, the AY slide table automatically moves left by a distance corresponding to the optical fiber diameter, so that the optical fiber led out from the inner shaft of the A guide wheel frame mechanism and the optical fiber ring skeleton always maintain a constant fiber inlet angle, which is conducive to neat fiber arrangement. After the first layer of optical fiber is arranged to the left edge of the optical fiber ring skeleton, the first layer winding ends.
[0038] Enter the second layer of winding loop. Except that the fiber arranging direction of the AY slide is automatically reversed, other moving mechanisms are in the same state as those in the first layer of winding loop until the end of the second layer of winding loop, and the base winding is completed.
[0039] Preferably, when winding 60 layers of fiber optic loops with a four-pole winding method with glue, the process is as follows:
[0040] The main control system automatically moves the A head and the B head to the fiber loading operation position. The operator sets the A fiber spool on the A outer shaft mechanism of the A head, sets the B fiber spool on the B outer shaft mechanism of the B head, and positions and adsorbs the fiber optic loop skeleton on the inner shaft end face of the B guide wheel frame mechanism of the B head.
[0041] The fibers on the A fiber spool and the B fiber spool have the same length. The fiber of the A fiber spool is introduced into the fiber optic loop skeleton through the inner shaft of the A guide wheel frame mechanism, and the fiber of the B fiber spool is introduced into the fiber optic loop skeleton through the inner shaft of the B guide wheel frame mechanism.
[0042] The operating equipment continues to run. The main control system automatically moves the A head and the B head to the first layer winding position. During the running process, the fiber spools on the A head and the B head will adaptively rotate through the PID control algorithm of the main control system to ensure that the fibers connected to the fiber optic loop skeleton from the A head and the B head always maintain a constant tension to prevent fiber damage.
[0043] Then the winding loop movement starts. The B outer shaft mechanism and the inner shaft of the B guide wheel frame mechanism drive the fiber optic loop skeleton to rotate synchronously to wind up the fiber. The inner shaft of the A guide wheel frame mechanism does not move. The A fiber spool rotates under the drive of the A outer shaft mechanism and releases the fiber onto the fiber optic loop skeleton.
[0044] During the fiber winding process, the fiber tension is detected in real time through a tension sensor, and the fiber winding and releasing speeds are automatically configured through the PID control algorithm of the main control system to keep the fiber under a constant tension all the time. The fiber winding length can be obtained through a length measuring encoder.
[0045] The first turn of the fiber in the first layer is close to the right edge of the fiber optic loop skeleton, and then is closely spirally arranged to the left of the fiber optic loop skeleton. During the fiber winding process, every time one turn of fiber is wound, the AY slide automatically moves left by a distance corresponding to the fiber diameter, so that the fiber led out from the inner shaft of the A guide wheel frame mechanism by the A fiber spool and the fiber optic loop skeleton always maintain a constant fiber inlet angle, which is beneficial to the neat arrangement of the fibers. After the fibers in the first layer are arranged to the left edge of the fiber optic loop skeleton, the first layer of winding loop ends.
[0046] For the second layer of winding, the equipment first automatically changes the spool, and then starts the winding loop movement. The A outer shaft mechanism and the inner shaft of the A guide wheel frame mechanism drive the fiber optic loop skeleton to rotate synchronously to wind up the fiber. The inner shaft of the B guide wheel frame mechanism does not move. The B fiber spool rotates under the drive of the B outer shaft mechanism and releases the fiber onto the fiber optic loop skeleton. The BY slide in the second layer is used as the fiber arranging drive mechanism, and the fiber arranging principle is the same as that in the first layer, and the fiber arranging direction is from right to left.
[0047] The third layer is wound. The fiber arranging direction of the BY slide is from left to right until the winding of the third layer around the loop is completed;
[0048] The fourth layer is wound. First, the equipment automatically changes the coil, and then starts the loop winding movement. The fiber arranging direction of the AY slide is from left to right until the winding of the fourth layer around the loop is completed;
[0049] The first to the fourth layers form a four-pole cycle, and the fifth to the eighth layers form the second four-pole cycle. The loop winding movements of each cycle are the same; for the fifth layer, the fiber arranging direction and the movement mechanism are the same as those in the first layer's loop winding state; for the sixth layer, the coil changing and loop winding movements are the same as those in the second layer... until the sixtieth layer, the loop winding is completed.
[0050] Preferably, when winding a sixty-four-layer fiber optic loop using the eight-pole winding method, the process is as follows:
[0051] The main control system automatically moves the A head and the B head to the fiber loading operation position. The operator sets the A fiber coil on the A outer shaft mechanism of the A head, sets the B fiber coil on the B outer shaft mechanism of the B head, and positions and adsorbs the fiber optic loop skeleton on the inner shaft end face of the B guide wheel frame mechanism of the B head.
[0052] The A fiber coil and the B fiber coil have the same length of optical fiber. The optical fiber of the A fiber coil is introduced into the fiber optic loop skeleton through the inner shaft of the A guide wheel frame mechanism, and the optical fiber of the B fiber coil is introduced into the fiber optic loop skeleton through the inner shaft of the B guide wheel frame mechanism.
[0053] Operate the equipment to continue running. The main control system automatically moves the A head and the B head to the position of the first layer of loop winding (step ② of Figure 9 ). During the running process, the fiber coils on the A head and the B head will adaptively rotate through the PID control algorithm of the main control system to ensure that the optical fibers connected to the fiber optic loop skeleton from the A head and the B head always maintain a constant tension to prevent optical fiber damage;
[0054] Then start the loop winding movement. The B outer shaft mechanism and the inner shaft of the B guide wheel frame mechanism drive the fiber optic loop skeleton to rotate synchronously to wind the fiber. The inner shaft of the A guide wheel frame mechanism does not move, and the A fiber coil rotates under the drive of the A outer shaft mechanism and releases the optical fiber onto the fiber optic loop skeleton;
[0055] During the fiber winding process, the fiber tension is detected in real time through a tension sensor, and the fiber winding and releasing speeds are automatically configured through the PID control algorithm of the main control system to keep the optical fiber at a constant tension at all times; the fiber winding length can be obtained through a length measuring encoder;
[0056] The first turn of the optical fiber in the first layer is closely attached to the right edge of the optical fiber ring skeleton, and then it is tightly spirally arranged to the left of the optical fiber ring skeleton. During the process of winding the optical fiber, every time a turn of the optical fiber is wound, the AY slide automatically moves leftward by a distance corresponding to the diameter of the optical fiber, so that the optical fiber led out from the inner shaft of the A fiber pay-off reel and the optical fiber ring skeleton always maintain a constant fiber inlet angle, which is beneficial to the neat arrangement of the optical fiber. After the first layer of optical fiber is arranged to the left edge of the optical fiber ring skeleton, the winding of the first layer around the ring is completed.
[0057] For the winding of the second layer, the equipment first automatically changes the reel, and then starts the winding movement around the ring. The outer shaft mechanism of A and the inner shaft of the A guide wheel frame mechanism drive the optical fiber ring skeleton to rotate synchronously for fiber take-up. The inner shaft of the B guide wheel frame mechanism remains stationary. The B fiber pay-off reel rotates under the drive of the outer shaft mechanism of B and releases the optical fiber onto the optical fiber ring skeleton. The BY slide in the second layer serves as the fiber arranging drive mechanism, and the fiber arranging principle is the same as that of the first layer, and the fiber arranging direction is from right to left.
[0058] For the winding of the third layer, the fiber arranging direction of the BY slide is from left to right until the winding of the third layer around the ring is completed.
[0059] For the winding of the fourth layer, the equipment first automatically changes the reel, and then starts the winding movement around the ring. The fiber arranging direction of the AY slide is from left to right, and the other movement mechanisms are the same as those in the winding state of the first layer until the winding of the fourth layer around the ring is completed.
[0060] For the winding of the fifth layer, the equipment first automatically changes the reel, and at the same time the lifting turntable drives the optical fiber ring skeleton to rotate counterclockwise by a certain degree, and then starts the winding movement around the ring. The A head drives the optical fiber ring skeleton to take up fiber, the B head pays off fiber, and the BY slide arranges fiber, and the fiber arranging direction is from left to right.
[0061] For the winding of the sixth layer, the equipment first automatically changes the reel, and then starts the winding movement around the ring. The B head drives the optical fiber ring skeleton to take up fiber and the A head pays off fiber, and the AY slide arranges fiber, and the fiber arranging direction is from left to right.
[0062] For the winding of the seventh layer, the fiber arranging direction is from right to left, and the other movement mechanisms are the same as those in the winding state of the sixth layer.
[0063] For the winding of the eighth layer, the equipment first automatically changes the reel, and then starts the winding movement around the ring. The fiber arranging direction is from right to left, and the other movement mechanisms are the same as those in the winding state of the fifth layer.
[0064] The first to the eighth layers form an eight-pole cycle, and the ninth to the sixteenth layers form the second eight-pole cycle. The winding movement of each cycle is the same. For the ninth layer, the equipment first automatically changes the reel, and at the same time the lifting turntable drives the optical fiber ring skeleton to rotate clockwise by a certain degree, and then starts the winding movement around the ring. The fiber arranging direction and the movement mechanisms are the same as those in the winding state of the first layer. For the tenth layer, the reel changing and the winding movement are the same as those of the second layer... until the sixty-fourth layer, the winding around the ring is completed.
[0065] Preferably, when winding a 64-layer fiber optic ring using a 16-pole winding method, the process is as follows: The main control system automatically moves the A head and the B head to the fiber loading operation position. The operator installs the A fiber spool on the A outer shaft mechanism of the A head, installs the B fiber spool on the B outer shaft mechanism of the B head, and positions and adsorbs the fiber optic ring skeleton on the inner shaft end face of the B guide wheel frame mechanism of the B head;
[0066] The A fiber spool and the B fiber spool have fibers of the same length. The fiber of the A fiber spool is introduced into the fiber optic ring skeleton through the inner shaft of the A guide wheel frame mechanism, and the fiber of the B fiber spool is introduced into the fiber optic ring skeleton through the inner shaft of the B guide wheel frame mechanism.
[0067] The operating equipment continues to run. The main control system automatically moves the A head and the B head to the first layer winding position. During the running process, the fiber spools on the A head and the B head will adaptively rotate through the PID control algorithm of the main control system to ensure that the fibers connected to the fiber optic ring skeleton from the A head and the B head always maintain a constant tension to prevent fiber damage;
[0068] Then the winding movement starts. The B outer shaft mechanism and the inner shaft of the B guide wheel frame mechanism drive the fiber optic ring skeleton to rotate synchronously to wind the fiber. The inner shaft of the A guide wheel frame mechanism does not move, and the A fiber spool rotates under the drive of the A outer shaft mechanism and releases the fiber onto the fiber optic ring skeleton;
[0069] During the fiber winding process, the fiber tension is detected in real time through a tension sensor, and the fiber winding and releasing speeds are automatically configured through the PID control algorithm of the main control system to keep the fiber always under a constant tension; the fiber winding length can be obtained through a length measuring encoder;
[0070] The first turn of the fiber in the first layer is close to the right edge of the fiber optic ring skeleton, and then spirally arranged tightly to the left of the fiber optic ring skeleton. During the fiber winding process, every time a turn of fiber is wound, the AY slide automatically moves left by a distance corresponding to the fiber diameter, so that the fiber led out from the inner shaft of the A guide wheel frame mechanism by the A fiber spool and the fiber optic ring skeleton always maintain a constant fiber inlet angle, which is beneficial to the neat arrangement of the fiber; after the first layer of fiber is arranged to the left edge of the fiber optic ring skeleton, the first layer winding ends;

For the eighteenth layer, the automatic coil changing action, the fiber laying direction, and the motion mechanism are the same as those of the second layer during looping... until the sixty-fourth layer, the looping is completed.
[0087] The present invention can achieve the following beneficial effects:
[0088] 1. The two sides of the optical fiber loop skeleton of the present invention can be magnetically attracted to the end faces of the A head and the B head. At the same time, coaxial positioning can be achieved through the positioning pins of the optical fiber loop skeleton and the positioning holes of the A head and the B head, so that the A head and the B head can drive the attracted optical fiber loop skeleton to move synchronously when they move.
[0089] 2. The system of the present invention has an automatic gluing function. Each of the A head and the B head has a set of gluing systems. During the looping process, the gluing system is automatically switched into the looping process and automatically exits the gluing function during the processes of fiber retraction, coil changing, and other processes that do not require gluing.
[0090] 3. The present invention can achieve the function of automatically switching the fiber feeding coil. According to the looping process requirements such as four-pole symmetry, eight-pole symmetry, and sixteen-pole symmetry, through the machine tool motion control system, the required head is automatically moved as the fiber feeding mechanism to the looping position of the optical fiber loop skeleton, and the other head is moved as the fiber receiving mechanism to the fiber receiving position. Preferably, the five sets of linear motion mechanisms and the three sets of turntable mechanisms of the machine tool motion control system are driven by absolute value type servo motors, so that the positioning of each moving mechanism is accurate and the positioning data is not affected by power on and off.
[0091] 4. The present invention can achieve the function of automatic fiber laying. After determining the fiber feeding mechanism and the fiber receiving mechanism through the machine tool motion control system, the machine tool corresponding to the fiber feeding mechanism can translate at a certain speed, and this speed is always positively correlated with the rotational speed of the fiber receiving mechanism, so that a constant fiber inlet angle is always maintained between the optical fiber led out by the fiber feeding mechanism and the optical fiber loop skeleton, thereby achieving the function of automatic fiber laying.
[0092] 5. The present invention can achieve the functions of automatic fiber winding and unwinding. The A head of the fiber winding control system is provided with a set of coaxial shaft structures. The outer shaft can drive the A fiber pay-off reel to rotate, and the inner shaft can drive the A guide wheel frame to rotate. The end face of the inner shaft can also attract the fiber loop skeleton through a permanent magnet, so that the fiber loop skeleton rotates coaxially and synchronously with the inner shaft. The outer shaft and the inner shaft are each driven by a set of absolute value servo motors. The control principle of the B head of the fiber winding control system is the same as that of the A head, and the structure is mirror-imaged. After the pay-off mechanism and the fiber take-up mechanism are determined by the machine tool motion control system, the fiber winding control system automatically makes the outer shaft and the inner shaft of the fiber take-up mechanism rotate synchronously. At this time, the fiber loop skeleton is attracted to the inner shaft of the fiber take-up mechanism and rotates synchronously with the fiber pay-off reel and the guide wheel frame of the fiber take-up mechanism; the inner shaft of the pay-off mechanism controls the guide wheel frame to keep the zero position stationary, and the outer shaft of the pay-off mechanism drives the fiber pay-off reel of the pay-off mechanism to pay off the fiber. During the process of the fiber pay-off reel of the pay-off mechanism paying off the fiber and the fiber loop skeleton of the fiber take-up mechanism taking up the fiber, the fiber tension is measured in real time by the tension sensor on the head of the pay-off mechanism. By introducing the pay-off speed, the take-up speed, and the fiber tension into the PID closed-loop control algorithm, a stable winding speed and a stable tension can be achieved. When the system detects that unwinding is required, the winding speed is automatically decelerated to zero, and then both the pay-off direction and the take-up direction are reversed and accelerated to a predetermined value, and the unwinding function can be realized again through the PID closed-loop control algorithm.
[0093] 6. The present invention can achieve the function of automatic layer change, including the increase in the number of layers from the first layer to the Nth layer. During normal winding, after the winding of the current layer is completed, it enters the next layer. According to the winding process, it may be necessary to operate to switch the fiber pay-off reel, and the equipment will automatically handle it. After the switching of the fiber pay-off reel is completed, it automatically enters the winding of the next layer, and so on, until the required number of layers is reached.
[0094] 7. The present invention can achieve the functions of intelligent unwinding and layer retreat, including unwinding from the current turn of the current layer to the first turn, and retreating layer by layer from the current layer to the first layer. The equipment automatically handles the unwinding and reel-changing actions. When an abnormal situation occurs during winding, it may be necessary to unwind several turns, one layer or even multiple layers. First, the winding image recognition system identifies the winding defect and sends an instruction to the main control system. The main control system automatically performs the unwinding and layer retreat actions according to different layer retreat instructions until the winding image recognition system determines that the winding defect has been eliminated.
[0095] 8. The present invention can achieve the coaxial rotation function. When a long pause is required during the winding around the ring, to ensure uniform distribution of glue on the ring body, it is necessary to make the fiber optic ring skeleton rotate slowly at a low speed without removing the fiber feeding disk, without damaging the fiber arrangement state of the already wound fiber optic ring, and while maintaining the stability of the fiber tension. Through the cooperation of the machine motion control system and the fiber optic ring winding control system, the fiber feeding head, the fiber optic ring skeleton, and the fiber collecting head can be run to a coaxial state. The inner and outer shafts of the fiber collecting head and the fiber optic ring skeleton are already in a magnetic adsorption state. The synchronous rotation of the inner and outer shafts of the fiber collecting head drives the rotation of the fiber optic ring skeleton, making the inner and outer shafts of the fiber feeding head rotate at the same speed and in the same direction as the inner and outer shafts of the fiber collecting head, thereby achieving the coaxial rotation function.
[0096] 9. The present invention can achieve the digitalization function during the winding process. The equipment is equipped with a rich variety of sensing and detection components, which can integrate a large number of process parameters such as fiber tension, fiber length, rotation speed, number and position of defects, etc. during the winding process, digitalize the winding process, and conduct real-time online analysis; it can also conduct comparative analysis in combination with the detection data after the production of the fiber optic ring, find out the factors affecting the quality of the fiber optic ring, and provide reverse guidance for the winding operation and control process.

Detailed implementation manners
[0112] Embodiment 1:
[0113] The disk changing motion is carried out through the machine table motion control system. As Figure 2-7 shown, the machine table motion control system has good degrees of freedom and control precision. Among them, the AY slide table 2 and the BY slide table 3 can respectively perform linear motion along the X direction on the first machine table guide rail 101 and the second machine table guide rail 102 of the machine table 1 under the drive of motors. The A head 6 can perform linear motion along the Y direction on the AY slide table 2 under the drive of a motor. The A head 6 can rotate on the tabletop of the A turntable 601 under the drive of a motor. The B head 7 can perform linear motion along the Y direction on the BY slide table 3 under the drive of a motor. The B head 7 can rotate on the tabletop of the B turntable 701 under the drive of a motor. The lifting turntable 4 can hold the optical fiber ring skeleton 5 and rotate or lift along the Z-axis direction.
[0114] As Figure 2 shown, the current state is the state where the B head 7 drives the optical fiber ring skeleton 5 to wind the optical fiber and the A head 6 pays off the optical fiber. The current layer has been wound, and it is necessary to control the A head 6 and the B head 7 to perform the disk changing motion to the next layer for winding. As Figure 8 shown, step ①, the lifting turntable 4 rises to hold the optical fiber ring skeleton, and then the motor drives the BY slide table 3 to move the B head 7 to the right and away from the optical fiber ring skeleton; steps ②-③, the multi-axis linkage of the machine table motion control system makes the A head 6 originally in the upper pay-off position move to the left winding position, and the B head 7 originally in the right winding position move to the lower pay-off position; step ④, the AY slide table 2 drives the A head 6 to move to the right to suck and hold the optical fiber ring skeleton 5, and then the lifting turntable 4 descends to release the optical fiber ring skeleton, and the disk changing is completed.
[0115] During the process of the disk changing movement, the fiber spools on the A head 6 and the B head 7 will adaptively rotate through the PID control algorithm of the main control system to ensure that the optical fibers connecting the A head 6 and the B head 7 to the optical fiber ring skeleton 5 always maintain a constant tension, so as to prevent optical fiber damage and the loosening of the optical fiber ring.
[0116] Embodiment 2:
[0117] Wind two layers of bottom layer optical fiber rings using the bottom winding method. First, set process parameters such as the optical fiber ring skeleton model, fiber arrangement spacing, and fiber winding speed required according to the winding process on the touch screen, and set the winding mode to the bottom layer mode. Then run the equipment, and the main control system automatically moves the A head 6 and the B head 7 to Figure 9 the upper fiber loading operation position shown in step ①. At this time, the equipment automatically pauses and waits. The operator sets the A fiber spool on the A outer shaft mechanism 602 of the A head 6, sets the B fiber spool on the B outer shaft mechanism 702 of the B head 7, positions and adsorbs the optical fiber ring skeleton 5 on the end face of the inner shaft 703 of the B guide wheel frame mechanism of the B head 7. There is a sufficient amount of bottom layer optical fiber on the A fiber spool, and the B fiber spool is an empty spool. Lead the optical fiber of the A fiber spool into the optical fiber ring skeleton through the inner shaft 603 of the A guide wheel frame mechanism, then into the inner shaft 703 of the B guide wheel frame mechanism, and finally into the B fiber spool and fix it on the B fiber spool with tape. Operate the equipment to continue running, and the main control system automatically moves the A head 6 and the B head 7 to Figure 9 the position shown in step ②. During the running process, the fiber spools on the A head 6 and the B head 7 will adaptively rotate through the PID control algorithm of the main control system to ensure that the optical fibers connecting the A head 6 and the B head 7 to the optical fiber ring skeleton 5 always maintain a constant tension, so as to prevent optical fiber damage.
[0118] Then start the winding movement. The B outer shaft mechanism 702 and the inner shaft 703 of the B guide wheel frame mechanism drive the optical fiber ring skeleton 5 to rotate and wind the fiber synchronously. The inner shaft 603 of the A guide wheel frame mechanism does not move. The A fiber spool rotates under the drive of the A outer shaft mechanism 602 and releases the optical fiber onto the optical fiber ring skeleton 5. During the fiber winding process, the optical fiber tension is detected in real time through the tension sensor, and the appropriate fiber winding and releasing speeds are automatically configured through the PID control algorithm of the main control system to keep the optical fiber under a constant tension at all times; the fiber winding length can be obtained through the length measuring encoder.
[0119] The first turn of the optical fiber in the first layer is closely attached to the right edge of the optical fiber ring skeleton 5, and then spirally arranged tightly to the left of the optical fiber ring skeleton 5. During the process of winding the optical fiber, every time a turn of the optical fiber is wound, the AY slide table 2 automatically moves leftward by a distance corresponding to the diameter of the optical fiber, so that the optical fiber led out from the inner shaft 603 of the A fiber feeding reel through the A guide wheel frame mechanism and the optical fiber ring skeleton 5 always maintain a constant fiber entry angle, which is beneficial to the neat arrangement of the optical fiber. After the first layer of optical fiber is arranged to the left edge of the optical fiber ring skeleton, the winding of the first layer around the ring ends, and the winding of the second layer around the ring begins. Except that the fiber discharging direction of the AY slide table 2 automatically reverses, other moving mechanisms are the same as those in the first layer of winding around the ring until the winding of the second layer around the ring ends and the bottom layer winding is completed.
[0120] Embodiment 3:
[0121] The optical fiber ring is wound with sixty layers of optical fibers by using the four-pole winding method with glue. The winding mode around the ring is set to the four-pole mode. The optical fibers on the A fiber feeding reel and the B fiber feeding reel have the same length. The optical fiber of the A fiber feeding reel is introduced into the optical fiber ring skeleton through the inner shaft 603 of the A guide wheel frame mechanism, and the optical fiber of the B fiber feeding reel is introduced into the optical fiber ring skeleton through the inner shaft 703 of the B guide wheel frame mechanism. The remaining fiber feeding operations and the winding of the first layer of the optical fiber ring are the same as those in Embodiment 2.
[0122] For the second layer of winding, the equipment first automatically changes the reel, as Figure 10 shown in step ②, and then starts the winding motion around the ring. The A outer shaft mechanism 602 and the inner shaft 603 of the A guide wheel frame mechanism drive the optical fiber ring skeleton 5 to rotate synchronously for fiber collection. The inner shaft 703 of the B guide wheel frame mechanism does not move, and the B fiber feeding reel rotates under the drive of the B outer shaft mechanism 702 and releases the optical fiber onto the optical fiber ring skeleton 5. The second layer BY slide table 3 is used as the fiber discharging drive mechanism, and the fiber discharging principle is the same as that of the first layer, and the fiber discharging direction is from right to left.
[0123] For the third layer of winding, as Figure 10 shown in step ③, the fiber discharging direction of the BY slide table 3 is from left to right, and other moving mechanisms are the same as those in the second layer of winding around the ring until the winding of the third layer around the ring ends.
[0124] For the fourth layer of winding, the equipment first automatically changes the reel, as Figure 10 shown in step ④, and then starts the winding motion around the ring. The fiber discharging direction of the AY slide table 2 is from left to right, and other moving mechanisms are the same as those in the first layer of winding around the ring until the winding of the fourth layer around the ring ends.
[0125] The first to the fourth layers are a four-pole cycle, and the fifth to the eighth layers are the second four-pole cycle. The winding motions of each cycle are the same. For the fifth layer, the fiber discharging direction and the moving mechanisms are the same as those in the first layer of winding around the ring; for the sixth layer, the reel changing and the winding motion are the same as those in the second layer... until the sixtieth layer, the winding around the ring is completed.
[0126] During the above-mentioned looping process, the gluing system automatically cuts in, extends the glue supply brush to the optical fiber. As the optical fiber is continuously wound into the optical fiber loop skeleton 5, the glue also automatically adheres to the optical fiber and is brought into the optical fiber loop skeleton 5. The amount of glue is controlled by a precision dispensing machine. During the processes of fiber unwinding, disk changing, and other processes that do not require gluing, the glue supply brush automatically retracts.
[0127] Example 4:
[0128] The sixty-four-layer optical fiber loop is wound using the eight-pole winding method. The winding mode is set to the eight-pole mode. The fiber feeding operation and the winding of the first to fourth layers of the optical fiber loop are the same as those in Example 3.
[0129] For the winding of the fifth layer, the equipment first automatically changes the disk. At the same time, the lifting turntable 4 drives the optical fiber loop skeleton 5 to rotate counterclockwise by 180 degrees. As shown in Figure 11 Step ⑤, then the looping motion starts. The A head 6 drives the optical fiber loop skeleton 5 to wind the fiber, the B head 7 pays out the fiber, and the BY slide 3 arranges the fiber. The fiber arrangement direction is from left to right.
[0130] For the winding of the sixth layer, the equipment first automatically changes the disk. As shown in Figure 11 Step ⑥, then the looping motion starts. The B head 7 drives the optical fiber loop skeleton 5 to wind the fiber, the A head 6 pays out the fiber, and the AY slide 2 arranges the fiber. The fiber arrangement direction is from left to right.
[0131] For the winding of the seventh layer, as shown in Figure 11 Step ⑦, the fiber arrangement direction is from right to left, and other moving mechanisms are the same as those in the sixth-layer looping state.
[0132] For the winding of the eighth layer, the equipment first automatically changes the disk. As shown in Figure 11 Step ⑧, then the looping motion starts. The fiber arrangement direction is from right to left, and other moving mechanisms are the same as those in the fifth-layer looping state.
[0133] The first to eighth layers are one eight-pole cycle. The ninth to sixteenth layers are the second eight-pole cycle. The looping motions of each cycle are the same. For the ninth layer, the equipment first automatically changes the disk. At the same time, the lifting turntable 4 drives the optical fiber loop skeleton 5 to rotate clockwise by 180 degrees. As shown in Figure 11 Step ①, then the looping motion starts. The fiber arrangement direction and the moving mechanisms are the same as those in the first-layer looping state; for the tenth layer, the disk changing and looping motion are the same as those in the second layer... until the sixty-fourth layer, the looping is completed.
[0134] Example 5:

[0136] For the winding of the ninth layer, as shown in Figure 12As shown in Step ⑨, the fiber arranging direction is from left to right, and other moving mechanisms are the same as those in the eighth layer winding state.
[0137] Winding of the tenth layer, as Figure 12 shown in Step ⑩, the automatic disk changing action, fiber arranging direction and moving mechanism are the same as those in the sixth layer winding state.
[0138] Winding of the eleventh layer, as Figure 12 shown in Step ⑪, the fiber arranging direction and moving mechanism are the same as those in the seventh layer winding state.
[0139] Winding of the twelfth layer, as Figure 12 shown in Step ⑫, the automatic disk changing action, fiber arranging direction and moving mechanism are the same as those in the eighth layer winding state.
[0140] Winding of the thirteenth layer, the equipment first automatically changes the disk, and at the same time the lifting turntable 4 drives the fiber optic ring skeleton 5 to rotate clockwise by 180 degrees, as Figure 12 shown in Step ⑬, and then starts the winding movement, and the fiber arranging direction and moving mechanism are the same as those in the first layer winding state.
[0141] Winding of the fourteenth layer, as Figure 12 shown in Step ⑭, the automatic disk changing action, fiber arranging direction and moving mechanism are the same as those in the second layer winding state.
[0142] Winding of the fifteenth layer, as Figure 12 shown in Step ⑮, the fiber arranging direction and moving mechanism are the same as those in the third layer winding state.
[0143] Winding of the sixteenth layer, as Figure 12 shown in Step ⑯, the automatic disk changing action, fiber arranging direction and moving mechanism are the same as those in the fourth layer winding state.
[0144] The first to the sixteenth layers are a sixteen-pole cycle, and the seventeenth to the thirty-second layers are the second sixteen-pole cycle. The winding movements of each cycle are the same. For the seventeenth layer, as Figure 12 shown in Step ①, the fiber arranging direction and moving mechanism are the same as those in the first layer winding state; for the eighteenth layer, as Figure 12 shown in Step ②, the automatic disk changing action, fiber arranging direction and moving mechanism are the same as those in the second layer winding state... until the sixty-fourth layer, the winding is completed.
[0145] Example 6:
[0146] A fiber optic ring with 108 layers is wound by the variable pole winding method. It is required to wind a four-pole cycle and an eight-pole cycle respectively, and then all use the sixteen-pole winding method. That is, the first to the fourth layers use the four-pole winding method, the fifth to the twelfth layers use the eight-pole winding method, and the thirteenth to the 108th layers use the sixteen-pole winding method.
[0147] First, set the winding mode to the quadrupole mode. The upper fiber operation and the winding of the first to fourth layers of fiber optic rings are the same as in Embodiment 3. Then, set the winding mode to the octupole mode and continue winding. Except for not needing to perform the upper fiber operation, the winding of the fifth to twelfth layers is the same as the winding of the first to eighth layers of fiber optic rings in Embodiment 4. Finally, set the winding mode to the hexadecapole mode and continue winding. Except for not needing to perform the upper fiber operation, the winding of the thirteenth to twenty-eighth layers is the same as the winding of the first to sixteenth layers of fiber optic rings in Embodiment 5. Subsequently, wind in a cycle according to the hexadecapole winding method until the one-hundred-and-eighth layer, and the winding is completed.
[0148] Embodiment 7:
[0149] When winding to the fiftieth layer according to the hexadecapole winding method, due to certain reasons, it is necessary to pause the winding for a long time. However, it is not desired that the glue drains under the action of gravity when the fiber optic ring stops rotating. At this time, the coaxial rotation function needs to be used.
[0150] When winding to the fiftieth layer according to the hexadecapole winding method, the operating state is as Figure 12 shown in Step ②. At this time, the fiber optic ring skeleton 5 is attracted to the A head 6. First, through the control of the machine tool motion control system, move the B head 7 to the Figure 13 position shown in State 1, and ensure that the optical fiber connecting the B head 7 to the fiber optic ring skeleton 5 always maintains a constant tension through the PID control algorithm of the main control system to prevent optical fiber damage. At this time, the A head 6, the fiber optic ring skeleton 5, and the B head 7 are coaxial. Then, drive the A head 6 to drive the fiber optic ring skeleton 5 to rotate through the fiber optic winding control system, and the B head 7 rotates synchronously with the A head 6, with the same rotation direction and speed. Thus, the continuous rotation of the fiber optic ring skeleton 5 can ensure the uniform self-flow of the glue.
[0151] When it is necessary to continue winding, move the B head 7 to the Figure 12 position shown in Step ② through the control of the machine tool motion control system, restore the winding state of the fiftieth layer, and then continue winding according to the normal operation.
[0152] Embodiment 8:
[0153] When winding to the fifth layer according to the quadrupole winding method, the winding image recognition system finds that there are defects on the ring surface. After being judged by the data analysis system, it is necessary to unwind this layer and the previous layer.
[0154] The device is at this time in the Figure 10 state shown in Step ①. The device automatically reverses the fiber receiving and fiber discharging directions and completes the unwinding of this layer. Then, it retreats to the fourth layer and completes the unwinding of the fourth layer. After the unwinding of the two layers is completed, the winding image recognition system finds that the defect still exists. After being judged by the data analysis system, it may be that the fiber diameter does not match the fiber optic ring skeleton, and it is necessary to unwind all.
[0155] The device is at this time in the Figure 10In the state shown in Step ④, the device automatically executes the reverse process of disk changing, running the device to Figure 10 the state shown in Step ③ and completing the unwinding of the third layer; after the device sequentially completes the unwinding of the second and first layers, it runs to Figure 10 the state shown in Step ①; finally, the device executes the reverse process of fiber threading, from Figure 9 the state shown in Step ② to Figure 9 the state shown in Step ①, and gives out an audible and visual alarm to remind the operator to take away the optical fiber and the optical fiber ring skeleton.
[0156] The present invention is not limited to the above embodiments. For example, winding different numbers of layers, adopting different combinations of pole-changing processes, winding bottom rings on the inner and outer circumferences of the optical fiber ring, etc. are all within the technical scope of the present invention. The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
