Detailed Description
The invention is further illustrated with reference to the following figures and examples.
As shown in figure 1, the displacement type tension controlled full-automatic optical fiber winding system of the invention is composed of a PLC automatic control part (a PLC controller, a take-up motor 5, a pay-off stepping motor 1, a driver, an electrical element and the like), a mechanical feeding system (a feeding motor 2, a driver and a ball screw 3) and a displacement type tension controller, wherein all motors and detection electrical elements (photoelectric switches) are directly connected with a controlled core PLC, the movement speed of an optical fiber is determined according to the coating requirement, and corresponding pulses are respectively sent to the take-up motor 5, the pay-off stepping motor 1 and the stepping motor by the PLC according to the program setting, so that the linear speed of the take-up motor 5 is always constant coating speed. When the take-up motor 5 rotates, the feeding motor 2 drives the ball screw 3 to move, and the position of the optical fibers is controlled by the guide wheel on the working platform of the device, so that the optical fibers are ensured to be closely arranged. The precision of the ball screw 3 is determined according to the wire diameter and the take-up speed of the optical fiber, and the smaller the wire diameter is, the slower the take-up speed is, and the higher the precision of the ball screw 3 is required. The rotation speed of the take-up motor 5 and the pay-off stepping motor 1 is adjusted along with the change of the number of the optical fiber layers on the respective reel, so that the linear speed of the optical fiber movement is always ensured to be constant.
By the method, the winding speed needs to be adjusted by a tension control instrument. If the tension sensor in the traditional tension control system is used for measuring the tension applied to the optical fiber, the sensor is contacted with the surface of the optical fiber, so that the optical fiber and the metal film layer are easily damaged, and the method is not suitable for winding the optical fiber. In the displacement type tension-controlled full-automatic optical fiber winding system, the winding speed is adjusted by detecting the displacement of the optical fiber wire guide wheel, all the wire guide wheels in contact with the optical fiber are arc surfaces, and the tension loaded on the optical fiber is controlled to be 10-15 g, so that the optical fiber is ensured not to be damaged and broken.
As shown in fig. 1-2, after the optical fiber is paid out by the pay-off reel, the optical fiber bypasses the guide wheel on the displacement type tension controller, when the tension on the optical fiber changes, the optical fiber can drive the pulley in the middle to move up and down, and four photoelectric switch detection points are arranged on the side edge of the displacement type tension controller:
when the detection point 2 (namely the speed-up position of the pay-off motor) detects a signal, which indicates that the rotation speed of the pay-off stepping motor 1 is too high, the pay-off stepping motor 1 is accelerated properly;
when the detection point 3 (namely the speed reduction position of the pay-off motor) detects a signal, the speed of the pay-off stepping motor 1 is too slow, and the pay-off stepping motor 1 is properly decelerated;
the displacement type tension controller is also provided with two sudden stop protection points of a detection point 1 and a detection point 4, and if the speed of the pay-off stepping motor 1 is too high (the detection point 4) or too low (the detection point 1), the whole winding system automatically stops to be adjusted by an operator.
