[0018] Figure 1 It is a structural schematic diagram of the present invention. Detailed implementation manners

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] See Figure 1 , an automatic calibration and cable stripping system for multi-specification optical cables is disclosed in the embodiments of the present invention, including: An automatic calibration clamping module, an electric drive and intelligent control module, a cable stripping mechanism module, a time delay monitoring and compensation module, an optical cable protection and cleaning module, and a safety protection module; Among them, the automatic calibration clamping module is connected to the electric drive and intelligent control module, receives its instructions and feeds back the clamping state; it stably fixes the optical cable for the cable stripping mechanism module.

[0021] The electric drive and intelligent control module is connected to the automatic calibration clamping module, the cable stripping mechanism module, the time delay monitoring and compensation module, and the safety protection module, receives the feedback and sends control instructions.

[0022] The cable stripping mechanism module is connected to the electric drive and intelligent control module, receives the instructions and feeds back the progress depth; it is connected to the time delay monitoring and compensation module, provides cable stripping action information; it is connected to the optical cable protection and cleaning module, and triggers cleaning after cable stripping.

[0023] The time delay monitoring and compensation module is connected to the electric drive and intelligent control module and the cable stripping mechanism module, collects data and sends correction instructions.

[0024] The optical cable protection and cleaning module is only connected to the cable stripping mechanism module, and receives its cable stripping completion signal to start cleaning.

[0025] The safety protection module is connected to the automatic calibration clamping module and the electric drive and intelligent control module, monitors the state and controls the machine to stop in case of abnormality.

[0026] Specifically, in the entire system, each module is closely connected and collaborates. The electric drive and intelligent control module is the core hub, receiving feedback from other modules and coordinating the actions of each module. The pressure sensor of the automatic calibration clamping module feeds back the clamping state to it and adjusts the clamping according to the instructions; the laser sensor of the cable stripping mechanism module feeds back the cable stripping depth and receives action instructions; the time delay monitoring and compensation module collects time parameters, processes them, and issues correction instructions. After the cable stripping is completed, the cable protection and cleaning module receives the signal from the cable stripping mechanism module and starts cleaning. The safety protection module monitors the motor load and directly controls the power sources of each module to stop in case of abnormality to ensure safety.

[0027] In a specific embodiment, the automatic calibration clamping module includes at least 3 jaws (4 jaws are selected in this embodiment) distributed circumferentially, driven by springs or cylinders, capable of automatically and dynamically adjusting the clamping force and angle according to the outer diameter of the optical cable, using a pressure sensor to monitor the clamping state in real time and feedback the data to the main control module, and ensuring the alignment of the optical cable axis with the center of the cable stripping mechanism through an automatic centering algorithm.

[0028] Specifically, the jaws are made of high-strength and wear-resistant materials to ensure that they are not easily damaged during long-term use. The type selection of the spring or cylinder is calculated and determined according to the maximum and minimum outer diameters of common optical cables and the required clamping force. A high-precision type of pressure sensor is selected and installed at the contact part between the jaw and the optical cable to ensure accurate feedback of the clamping state.

[0029] Specifically, the preset automatic centering algorithm model is implemented by programming, transmitting the data collected by the pressure sensor to the control system for analysis and processing, and then controlling the actions of the jaws to achieve centering.

[0030] Specifically, in the process of automatic centering, the core idea is to judge whether the position of the optical cable is in the center based on the pressure data collected by the pressure sensors on each jaw. If the pressures on each jaw are not balanced, it means that the optical cable is eccentric. At this time, the positions of the jaws need to be adjusted until the pressures on each jaw reach balance, so as to achieve the centering of the optical cable.

[0031] More specifically, the program of the automatic centering algorithm model is as follows: import numpy as np # Preset parameters n = 4 # Number of jaws P_avg = 10 # Preset ideal average pressure value k = 0.1 # Adjustment coefficient error_threshold = 0.1 # Allowable pressure deviation error range # Simulate initial jaw pressure values P = np.array([8, 12, 9, 11]) # Initial position of the gripper x_old = np.zeros(n) # Implementation of the automatic centering algorithm while True: # Calculate the current average pressure value P_current_avg = np.mean(P) # Calculate the deviation of each gripper pressure from the average pressure delta_P = P - P_current_avg # Determine if the error range is reached if np.all(np.abs(delta_P) < error_threshold): break # Calculate the adjustment amount of the gripper delta_x = k * delta_P # Update the gripper position x_new = x_old + delta_x # Simulate the pressure value after update (need to re-collect in practice) # Here, it is simply assumed that the pressure is linearly related to the position P = P + delta_x x_old = x_new print("Centering completed, final gripper position:", x_new)。

[0032] In the above code, by simulating the pressure values and positions of the grippers, the iterative process of the automatic centering algorithm is realized until the pressure deviation of the grippers is within the allowable error range, and it is considered that the optical cable has been centered.

[0033] In a specific embodiment, the electric drive and the intelligent control module use the PID algorithm to control the motor speed and torque, can automatically and dynamically adjust the output according to the optical cable material, are provided with a touch screen for real-time display of the cable stripping parameters, support manual fine-tuning and preset mode switching, receive correction instructions from the automatic calibration related module, and control the coordinated operation of the cable stripping mechanism and the clamping module.

[0034] Specifically, the motor was selected to feature high torque and high-precision control, optimally matched to the transmission mechanism. The PID algorithm parameters were determined through experimental debugging to achieve optimal control. The touch screen was an industrial-grade product with excellent interference resistance and stability. Regarding software, a dedicated control program was developed to enable parameter display, manual fine-tuning, preset mode switching, and communication with other modules.

[0035] In a specific embodiment, the cable stripping mechanism module has a modular blade assembly, which can quickly replace the blade to adapt to different optical cable specifications. The integrated laser sensor monitors the cable stripping depth in real time, can automatically and dynamically adjust the blade cutting amount according to the monitoring results, receive control system instructions and feedback the stripping progress to the main control module.

[0036] Specifically, the modular cutter head assembly features various cutter head types designed to suit different cable specifications, with a quick-swap design for easy replacement. A laser sensor is installed near the cutter head to accurately monitor the cable stripping depth. A correlation between laser sensor data and cutter head penetration is established, enabling precise adjustment of the cutter head penetration through a control program.

[0037] In a specific embodiment, the delay monitoring and compensation module records the time parameters of each link of the cable stripping process through high-speed sensors to establish a delay baseline. When a delay deviation greater than 5% is detected, parameter freezing and an alarm are triggered. Based on historical data, the aging trend is predicted, and the motor response curve and the blade compensation amount are automatically and dynamically adjusted. Correction instructions are sent to the control system in real time to ensure synchronization of the cable stripping timing.

[0038] Specifically, high-speed sensors (such as photoelectric encoders) are installed on the motor shaft or key transmission components to accurately record the time parameters of each cable stripping step. A data storage unit records historical data, and an appropriate prediction algorithm (such as a machine learning algorithm) is used to predict aging trends. A compensation algorithm is programmed to dynamically adjust the motor response curve and blade compensation based on the prediction results and real-time monitored delay deviations.

[0039] In a specific embodiment, the optical cable protection and cleaning module uses an arc-shaped guide wheel to form a flexible guide structure to prevent excessive bending of the optical fiber. After the optical cable stripping is completed, the pneumatic cleaning unit uses high-pressure airflow to automatically remove debris on the surface of the optical fiber, and the cleaning action is triggered in conjunction with the cable stripping mechanism.

[0040] Specifically, the curved guide wheel is made of a smooth, low-friction material, and its curvature is designed based on the minimum bend radius of the optical fiber. The pneumatic cleaning unit is equipped with a high-pressure air source and a suitable nozzle. The nozzle's position and angle are optimized to ensure effective removal of debris from the optical fiber surface. This is linked to the cable stripping mechanism through a control circuit.

[0041] In a specific embodiment, the safety protection module monitors the motor load through a current sensor. When the load exceeds the limit, it automatically reduces the speed or cuts off the power supply. A dual-redundant emergency stop button is set to cut off all power sources with one key, and it has an independent hardware circuit, whose priority is higher than that of other modules.

[0042] Specifically, a current sensor with high precision and fast response speed is selected and installed on the motor power supply line. The emergency stop button adopts a large-size and eye-catching design, which is convenient for the operator to quickly operate in an emergency. The independent hardware circuit is realized through a specially designed circuit board to ensure that the safety protection function can still work normally when other parts of the system fail.

[0043] Specifically, the system working process is as follows: Initialization: The operator selects the optical cable type through the human-machine interface, and the system automatically loads the corresponding parameters (blade model, cable stripping depth, etc.).

[0044] Adaptive clamping: The optical cable is sent into the clamping module, and the clamping jaws dynamically adjust to complete centering, and the pressure sensor feeds back a "ready" signal.

[0045] Cable stripping execution: The electric drive module is started, and the blade cuts into the outer sheath of the optical cable according to the preset path. At the same time, the time delay monitoring module compares the actual time sequence with the baseline in real time. If there is a deviation, it triggers a compensation instruction to correct the motor speed.

[0046] Optical fiber protection and cleaning: After the optical cable is stripped, the pneumatic cleaning unit is started to remove the debris on the surface of the optical fiber.

[0047] Safety monitoring: During the whole working process of the system, the safety protection module monitors the whole process. Once an abnormal situation occurs, the shutdown operation is preferentially executed.

[0048] Through the above implementation manners, the multi-specification optical cable adaptive stripping system can operate stably and efficiently, meet the stripping requirements of various specifications of optical cables, and provide reliable technical support for the optical cable processing work.

The same or similar parts among the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.
