Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of optical communication engineering construction equipment, specifically relating to a convenient strip optical cable stripping device. Background Technology
[0002] In the large-scale construction and maintenance of fiber-to-the-home, data centers, and 5G fronthaul networks, ribbon optical cables are widely used due to their high-density cores and ease of splicing. During on-site construction, the ends of the optical cable need to be stripped, that is, the outer sheath, aramid reinforcement layer, loose tube, etc., are removed layer by layer until the neatly arranged ribbon optical fiber units inside are exposed, in order to perform subsequent splicing or termination operations. The quality of this stripping process directly affects the efficiency of subsequent operations and the final performance of the optical fiber link.
[0003] Currently, on-site operations primarily rely on handheld or simple fixed-type convenient stripping tools. These tools typically include adjustable-depth cutting blades and mechanical limiting devices. Their working principle relies on the operator's experience to manually adjust the blade's cutting depth and limiting position beforehand according to the fiber optic cable model, and then apply appropriate force during operation to cut and strip the cable. However, in practical applications, it has been found that this method presents significant technical challenges and operational risks when handling ribbon fiber optic cables with multi-layered composite structures and internal fragile fiber coatings, specifically as follows: First, determining stripping parameters heavily relies on personal experience, lacking a unified and precise standard. Ribbon optical cables come in numerous models, and the physical properties of their various layers (such as polyethylene sheath, aramid yarn, PBT loose tube, and fiber UV-cured coating) vary between different manufacturers and batches. On-site operators often rely solely on visual inspection and experience to manually set tool parameters, such as cutter knob markings and limit stop positions. This experience-based approach cannot accurately match the actual material characteristics of the cable to be stripped, leading to inaccurate stripping depth control. Excessive cutting directly damages the internal ribbon fiber, causing fiber breakage or introducing microcracks, increasing optical signal transmission loss or even causing link interruption; while shallow cutting fails to effectively strip the target layer, requiring repeated operations, reducing efficiency, and potentially damaging the fiber due to accumulated stress. The fundamental reason is the lack of a way to quickly and accurately obtain the precise mechanical and structural parameters of a specific optical cable on-site, and the absence of readily available portable tools that can precisely adjust themselves based on these parameters.
[0004] Secondly, during the stripping process, especially when dealing with coatings or adhesive buffer layers adjacent to fragile fiber layers, there is a lack of real-time, precise force feedback and control mechanisms. Existing handy tools mainly provide mechanical depth limits, but in actual stripping operations, the push force manually applied by the operator is dynamic and difficult to maintain consistently. When the cutter contacts different material interfaces, the required stripping force changes abruptly. For example, when transitioning from a harder outer sheath to a softer loose tube, or when stripping a coating layer tightly bonded to the fiber, if the applied force is not detected and adjusted in time, it is easy to cause compression or scratches to the fiber, which is only tens of micrometers in diameter, due to instantaneous overload. Such damage is usually irreversible. The tools themselves generally do not integrate highly sensitive micro-force sensing and a fast-response closed-loop control system, and cannot automatically intervene (such as pausing or slightly retracting) when the preset safety force threshold is reached, thus failing to provide effective protection for the fragile fiber structure in the critical "last micrometer" operation. The challenge lies in the fact that, within the limited space and cost constraints of portable tools, integrating high-precision force sensors, achieving stable measurement of millinewton-level forces and millisecond-level real-time control, and ensuring their reliability in complex field environments, is an extremely challenging engineering problem.
[0005] Furthermore, tool wear is another dynamic variable affecting peeling quality. Cutting blades gradually wear down with increased use, their sharpness decreasing, leading to increased force required to complete the same peeling action. Without compensation for this, the safety force threshold calibrated based on new blades will no longer be applicable. Tools controlled by the old threshold will either malfunction due to frequent false alarms or lose their protective function due to the threshold being too low. Currently, operators typically judge whether the blade is "dull" by feel and roughly adjust their operating techniques or directly replace the blade, lacking a mechanism for dynamic and quantitative compensation of tool control parameters based on objective data (such as cumulative usage count).
[0006] In summary, the core problem with existing portable ribbon fiber optic cable stripping equipment lies in its over-reliance on manual experience for stripping precision (depth and force). Furthermore, the tools themselves lack the ability to adaptively preset based on the precise parameters of specific optical cables, and to provide real-time micro-force protection for fragile structures during operation. This results in common drawbacks such as unstable stripping quality, high risk of fiber damage, and strong dependence on skilled workers. Efforts to solve these problems are often limited by how to embed "precise sensing and intelligent control" functions into the tools while maintaining their inherent attributes of "convenience, low cost, and high reliability"—a long-standing contradiction. Summary of the Invention
[0007] One object of the present invention is to solve at least the above-mentioned problems and / or defects, and to provide at least the advantages described below.
[0008] One objective of this invention is to address how to make portable stripping equipment independent of the personal experience of on-site operators and to ensure standardized, high-precision, and low-damage stripping of the multi-layered fragile structure inside optical cables.
[0009] One object of the present invention is to provide a convenient strip optical cable stripping device, comprising a device body, a cutter adjustment mechanism mounted on the device body, and a control module, and further comprising: The remote collaborative control system consists of a remote management center and a control module of the device body connected via a wireless communication module. The remote management center is a data processing system deployed on a cloud server, configured to perform the following operations: Receive the model identification code of the optical cable to be stripped, uploaded by the wireless communication module of the device body; Based on the model identification code, the precision calibration parameter database is queried to obtain the set of safe stripping parameters uniquely corresponding to the model. The set of safe stripping parameters includes multiple precise depth values and multiple critical stripping force ranges corresponding to the safe stripping of the multi-layer structure of the optical cable to be stripped. The precision calibration parameter database includes multiple precise depth values and multiple critical stripping force ranges corresponding to the safe stripping of the multi-layer structure obtained by performing layer dissection and micro-force testing on optical cable samples of different models under standard laboratory conditions. The control command, which includes the multiple precise depth values and multiple critical peel force ranges, is sent to the control module of the device body; The control module of the device body is configured as follows: Receive and parse the control command; During the peeling process, the current working load of the tool is obtained in real time by a pressure sensor integrated on the tool adjustment mechanism, and the current cutting depth is obtained by a displacement sensor. For any layer of the optical cable to be stripped, when the current cutting depth reaches the precise depth value, the micro-force protection mode is activated. The micro-force protection mode includes: comparing the current tool working load with the critical stripping force range; if the current tool working load exceeds the upper limit of the critical stripping force range, controlling the tool adjustment mechanism to perform a pause or retraction action.
[0010] Preferably, in the aforementioned convenient ribbon optical cable stripping device, the multi-layer structure includes a stripping interface between the outer sheath layer and the loose tube, a separation interface between the loose tube and the optical fiber bundle, and a stripping interface for the optical fiber coating layer.
[0011] Preferably, in the aforementioned convenient ribbon optical cable stripping device, the control module is configured to execute the micro-force protection mode, which includes: Compare the current tool working load with the critical peeling force range; When the current tool working load reaches the preset range of the upper limit of the critical peeling force range, a pause hold command is generated; After the pause hold command has been executed for a preset duration, it is determined whether the current tool working load is still higher than the upper limit of the critical peel force range; if it is higher, a micro retraction command is triggered. The tool adjustment mechanism responds to the pause hold command and the micro retraction command by performing corresponding actions.
[0012] Preferably, in the aforementioned convenient strip optical cable stripping device, the preset range is 105% to 110% of the upper limit of the critical stripping force range, and the preset duration is 0.3 seconds to 0.8 seconds.
[0013] Preferably, in the aforementioned convenient strip optical cable stripping device, the distance by which the micro-retraction command controls the cutter to retract is 0.02 mm to 0.1 mm.
[0014] Preferably, in the aforementioned convenient ribbon optical cable stripping equipment, the remote management center also pre-stores a tool wear compensation parameter table, which is used to define the mapping relationship between the cumulative number of tool uses and the compensation coefficient; the remote management center is configured to perform the following operations: Receive the cumulative number of times the cutting tool has been used, uploaded by the wireless communication module of the device body; Based on the cumulative number of times the tool has been used, the corresponding compensation coefficient is obtained by querying the tool wear compensation parameter table, and based on the compensation rules, the upper limit of each critical peeling force range is compensated according to the compensation coefficient.
[0015] Preferably, in the aforementioned convenient ribbon optical cable stripping device, the compensation rule is as follows: multiply the compensation coefficient by the upper limit of each standard critical stripping force range to obtain the upper limit of each compensated critical stripping force range.
[0016] Preferably, in the aforementioned convenient ribbon optical cable stripping device, the device body further includes a status indicator unit; after receiving a control command from the remote management center, the control module drives the status indicator unit to issue a first prompt signal; when the micro-force protection mode is activated, the control module drives the status indicator unit to issue a second prompt signal that is different from the first prompt signal.
[0017] Preferably, in the aforementioned convenient ribbon optical cable stripping device, the status indicator unit includes at least two different colored LED indicator lights, wherein the first indication signal is a constantly lit LED of the first color, and the second indication signal is a flashing LED of the second color.
[0018] The present invention has at least the following beneficial effects: This invention achieves precise and standardized distribution of stripping parameters by constructing a cloud-based precision calibration parameter library and a remote collaborative control system for on-site stripping equipment. This enables on-site equipment to automatically obtain matching precise depth and critical force parameters based on the optical cable type, effectively reducing reliance on the operator's personal experience. During the stripping process, by monitoring the load and depth in real time and actively protecting the fragile internal optical fiber structure based on preset force thresholds when reaching critical positions, technical protection is provided for the fragile internal optical fiber structure, thereby improving the consistency and reliability of the stripping operation.
[0019] This invention optimizes the dynamic process of micro-force protection by introducing a hierarchical response control mode that includes pause, hold judgment, and conditional deceleration. This mode provides the system with a brief buffer and self-adjustment time, distinguishing between instantaneous fluctuations and sustained overloads, thereby reducing potential malfunctions or protection hysteresis caused by instantaneous triggering of a single threshold. This makes the protection control more fault-tolerant and adaptable, improving the accuracy of actions and the smoothness of operation.
[0020] This invention introduces a wear compensation mechanism based on the number of times the tool has been used into the cloud management system, enabling the system to sense and respond to the key dynamic variable of tool status. By dynamically adjusting the issued critical force threshold, it compensates for changes in peeling force caused by tool wear, thereby extending the effective period of the micro-force protection function within a single tool regrinding cycle and maintaining the performance stability of the equipment during long-term use.
[0021] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description
[0022] Figure 1 This is a block diagram of the convenient strip optical cable stripping device described in this invention. Detailed Implementation
[0023] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.
[0024] like Figure 1As shown, this invention provides a convenient strip optical cable stripping device, including a device body, a cutter adjustment mechanism mounted on the device body, and a control module. It also includes a remote collaborative control system, which consists of a remote management center connected to the control module of the device body via a wireless communication module. The remote management center is a data processing system deployed on a cloud server, configured to perform the following operations: receive the model identification code of the optical cable to be stripped, uploaded by the wireless communication module of the device body; query a precision calibration parameter database based on the model identification code to obtain a set of safe stripping parameters uniquely corresponding to that model, the safe stripping parameter set including multiple precise depth values and multiple critical stripping force ranges corresponding to the safe stripping of the multi-layer structure of the optical cable to be stripped; the precision calibration parameter database includes data collected from samples of different optical cable models under standard laboratory conditions. Layered dissection and micro-force testing are performed to obtain multiple precise depth values and multiple critical peeling force ranges corresponding to the safe stripping of the multi-layered structure. Control commands containing these precise depth values and critical peeling force ranges are sent to the control module of the device body. The control module of the device body is configured to receive and parse the control commands. During the stripping process, the current tool working load is acquired in real time through a pressure sensor integrated on the tool adjustment mechanism, and the current cutting depth is acquired through a displacement sensor. For any layer of the optical cable to be stripped, when the current cutting depth reaches the precise depth value, a micro-force protection mode is activated. This micro-force protection mode includes comparing the current tool working load with the critical peeling force range; if the current tool working load exceeds the upper limit of the critical peeling force range, the tool adjustment mechanism is controlled to perform a pause or retraction action.
[0025] The present invention provides a convenient strip optical cable stripping device comprising a device body that is easy to hold or fix, wherein the device body is equipped with a cutting and stripping tool assembly, a control module, and a wireless module for communication.
[0026] During the preparation phase, operators first input the model identification information of the optical cable to be stripped into the equipment by scanning the barcode on the cable reel or manually entering it. This information is then uploaded wirelessly to a remote management center deployed on a cloud server. The remote management center has a pre-installed precision calibration parameter database. The records in this database were established by performing layer-by-layer dissection and stripping force tests on optical cable samples of different models and batches in a laboratory environment using standard metrology equipment. It systematically records the precise depth values and critical stripping force ranges corresponding to the safe stripping of each key interface, from the outer sheath to the inner fiber coating.
[0027] Based on the received optical cable model, the management center retrieves the matching set of safety stripping parameters from the database and encapsulates them into control commands, which are then sent to the field equipment. After receiving and parsing the command, the control module of the field equipment drives the micro-actuator to automatically adjust the cutter's depth and the position of the limit stop to the state specified in the command. Simultaneously, it alerts the operator via indicator lights or a simple display screen to indicate that the preset is complete.
[0028] Upon entering the stripping stage, the operator secures the optical cable and operates the equipment as usual. During stripping, a pressure sensor integrated into the cutter assembly continuously monitors the working load on the cutter, while a displacement sensor simultaneously monitors the cutting depth. The control module compares the current cutting depth with the precise depth values for each layer sent from the cloud in real time. When the cutting depth reaches, for example, the precise depth value corresponding to the fiber coating layer, the control module automatically activates the micro-force protection mode. In this mode, the system compares the real-time cutter working load with the upper limit of the critical stripping force range sent from the cloud for that coating. If the working load exceeds this upper limit, the control module immediately generates a control signal, instructing the cutter adjustment mechanism to pause feeding or perform a small retraction movement, thereby actively relieving excessive stress and preventing damage to the bare fiber underneath. After safely stripping the layer, the equipment can proceed to the next layer's processing flow or terminate the operation according to instructions.
[0029] The closest existing technology is the widely used purely mechanical or simple electromechanical stripping tools. Before operation, these tools rely entirely on the operator's personal experience to determine the fiber optic cable type and manually rotate knobs and move stops by feel to set the cutter depth and limits. Throughout the stripping process, whether the current layer is cut through, when to switch to the next layer, and whether the applied force is appropriate are all judged and adjusted based on the operator's subjective feelings such as hearing and touch. Especially when dealing with the innermost fragile fiber coating, extremely high concentration and manual control are required.
[0030] Compared to the existing technologies described above, the embodiments of this invention bring about substantial differences in working logic. It shifts the core process parameters required for peeling operations—namely, the precise depth and safe force range of each layer—from reliance on personal experience to a cloud database based on objective laboratory measurements. The field equipment is no longer a completely passive manual tool, but rather a terminal capable of receiving and executing precise parameter instructions. The core difference lies in the standardization and precise distribution and setting of peeling parameters through the introduction of a remote collaborative architecture; and in the integration of force and depth sensing, and real-time comparison and control based on objective thresholds distributed from the cloud, providing data-driven, automated micro-force protection intervention for internally vulnerable structures. This reduces excessive reliance on the operator's long-term experience and instantaneous judgment, aiming to transform the peeling process from a highly skill-dependent "craft" into a "process" with traceable parameters, controllable process, and more consistent results, thereby improving the predictability and reliability of operational quality.
[0031] In a preferred embodiment, the convenient ribbon optical cable stripping device includes a stripping interface between the outer sheath and the loose tube, a separation interface between the loose tube and the optical fiber bundle, and a stripping interface for the optical fiber coating layer.
[0032] When constructing the precise calibration parameter database for the remote management center, instead of conducting indiscriminate testing on all possible material layers of the optical cable, the calibration is focused on three easily defined physical interfaces that are crucial to the final stripping quality.
[0033] The first calibration interface is the peeling interface between the outer sheath and the inner loose tube. In the laboratory, a high-precision force gauge is used to record the force and corresponding cutting depth required to completely peel the polyethylene or PVC outer sheath of a specific type of optical cable from its internal PBT loose tube. The second calibration interface is the separation interface between the loose tube and the internal ribbon fiber bundle unit. This process involves separating the loose tube material from the bundled fiber ribbon, recording the force and precise depth required to complete the separation without deforming or unraveling the fiber ribbon. The third, and most refined, calibration interface is the fiber coating itself. Here, the maximum allowable peeling force and its corresponding operating depth are calibrated when the UV-cured acrylate coating surrounding a single fiber glass core is safely removed, exposing a clean glass surface. The depth values of these three interfaces constitute a progressive depth sequence, and their corresponding critical peeling force ranges form a graded set of force protection thresholds.
[0034] During on-site operations, when the equipment receives a control command for a specific type of optical cable, the command includes an array of precise depth values and an array of critical stripping force ranges corresponding to the three specific interfaces. During the stripping process, the equipment control module sequentially compares the current cutting depth with these three depth values. For example, when the value fed back by the depth sensor reaches the first calibrated depth, the system knows that the cutter has reached the interface between the outer sheath and the loose tube, and then invokes and monitors the critical stripping force range for that interface to provide protection. This process continues until the protective stripping of the innermost and most vulnerable fiber coating is completed.
[0035] In a preferred embodiment, in the convenient ribbon optical cable stripping device, the control module is configured to execute the micro-force protection mode, which includes: comparing the current tool working load with the critical stripping force range; when the current tool working load reaches a preset range of the upper limit of the critical stripping force range, generating a pause and hold command; after the pause and hold command has been executed for a preset duration, determining whether the current tool working load is still higher than the upper limit of the critical stripping force range; if it is higher, triggering a micro-retreat command; wherein, the tool adjustment mechanism responds to the pause and hold command and the micro-retreat command by performing corresponding actions.
[0036] In a specific implementation of the micro-force protection control logic of this invention, the control module is configured to execute a micro-force protection mode that includes a graded response. When the system determines that the current cutting depth has reached the precise depth value of the target layer based on the parameters sent from the cloud and activates the micro-force protection mode, this mode does not directly trigger a strong retraction action when the tool working load exceeds the critical upper limit at once, but executes a gentler, step-by-step control sequence.
[0037] First, the system continuously compares the real-time load with the critical upper limit value. When the load is detected to rise and reach a preset percentage range of the upper limit value, such as within five percent of the upper limit value, the control module generates a first-level command: a pause and hold command. This command does not immediately reverse the tool's movement, but rather instructs the tool adjustment mechanism to immediately stop the current feed motion and maintain the current depth position and pressure state for a preset short period of time, such as a fraction of a second. The purpose of this step is to provide the system with a brief period of stabilization.
[0038] During the pause and hold period, the system continuously monitors the working load. If, at the end of the hold period, the load has naturally decreased and fallen below the critical upper limit, indicating that the previous overload may have been just a momentary fluctuation or has been alleviated by the material's own relaxation, the system will deactivate the protection and allow the operator or equipment to continue normal peeling operations.
[0039] If, after the pause period, the system determines that the working load is still above the critical upper limit, this indicates that the overload is persistent and requires active intervention. At this point, the control module generates a second-level command: a micro-retraction command. This command controls the tool adjustment mechanism to perform a very small reverse displacement, such as retracting a few percent of a millimeter. Its purpose is to reduce the load by actively releasing a small portion of mechanical strain, moving it out of the danger zone. After completing this micro-retraction, the system will reassess the load status and determine subsequent operations.
[0040] When dealing with overload issues, two simple methods are typically used: one is to rely entirely on the operator's feel without any automatic protection, which is very risky; the other is to integrate a simple mechanical overload protection or circuit overcurrent protection into the tool. This protection mechanism usually sets a high fixed threshold, and once triggered (e.g., due to a sudden increase in resistance caused by cutting aramid or a hard object), its action is often to directly cut off the power or trigger a large, uncontrollable mechanical release action. This "one-size-fits-all" protection method is too harsh when dealing with delicate stripping near the fragile fiber layer: either the threshold is too high to trigger before actually damaging the fiber, rendering the protection meaningless; or it is falsely triggered due to instantaneous fluctuations, causing work interruption, and the large amplitude of the triggered action may damage the completed stripping surface, affecting the continuity of subsequent operations.
[0041] In contrast, the graded response strategy in this invention is designed to distinguish between transient disturbances and persistent hazards. It introduces a "pause-observation" buffer step, first attempting to eliminate brief overshoots caused by material inhomogeneity or operational jitter. Only when the hazard is confirmed to persist is a precise, minute corrective action taken. This approach makes the protection logic more discriminative and fault-tolerant, with the magnitude of its control actions more closely aligned with the target. It aims to achieve more refined and "gentle" protection for vulnerable structures, effectively preventing damage while minimizing interruptions and interference with the normal stripping process, thus improving the practicality and reliability of the protection function.
[0042] In a preferred embodiment, in the convenient strip optical cable stripping device, the preset range is 105% to 110% of the upper limit of the critical stripping force range, and the preset duration is 0.3 seconds to 0.8 seconds.
[0043] During the equipment manufacturing or system commissioning phase, two key parameters in the micro-force protection mode are set within a specific numerical range.
[0044] The load range for triggering the pause and hold command is set at 5% to 10% above the upper limit of the critical peeling force range. This means that when the system detects that the real-time load reaches 105% of this upper limit, it enters the early warning and intervention preparation phase; and when the load reaches 110% of the upper limit, it is a clear boundary requiring intervention. This range is designed to take into account the slight noise that may exist in the sensor signal and the normal force fluctuations during the peeling process, avoiding excessively frequent false triggers due to minor disturbances.
[0045] Meanwhile, the execution duration of the pause-and-hold command is set between 0.3 and 0.8 seconds. This timeframe is chosen to balance two needs: first, to provide sufficient time for material stress relaxation or the dissipation of transient disturbances; and second, to avoid delays in taking further protective measures when there is a genuine risk of sustained overload due to excessively long waiting times. The specific duration can be selected within this range based on the typical viscoelasticity of the optical cable coating material or user experience.
[0046] In actual operation, the control module operates based on specific values preset within this range. For example, it can be set to trigger a pause when the load reaches 106% of the upper limit and remain there for 0.5 seconds for observation. This injects precise and reproducible numerical definitions into the originally descriptive control logic.
[0047] This invention provides a clear numerical range for the control logic, making the characteristics of the protection behavior quantifiable, predictable, and adjustable. It allows for the selection of more sensitive or robust parameter combinations within a reasonable range, depending on the application scenario. This method of clearly defining the range of key control parameters transforms the micro-force protection function from a black box or uncontrollable mechanism into a technical feature whose response characteristics can be clearly understood, set, and reproduced. This helps achieve consistent protection effects and facilitates standardized performance verification and debugging under different equipment or operating conditions.
[0048] In a preferred embodiment, in the convenient strip optical cable stripping device, the distance by which the micro-retraction command controls the cutter to retract is 0.02 mm to 0.1 mm.
[0049] When the graded response strategy in the micro-force protection mode determines that final correction needs to be performed, i.e., when the micro-retraction command is triggered, its control objective is to make the tool produce a small reverse displacement.
[0050] The retraction distance is implemented as a value between 0.02 mm and 0.1 mm. This scale is much smaller than the feed step of the tool or the thickness of a single layer of material in conventional peeling operations. In practice, the control module sends a corresponding number of pulses or a tiny position adjustment command to the drive unit of the tool adjustment mechanism based on a specific value preset within this range. For example, each micro-retraction movement can be set to 0.05 mm.
[0051] The intention behind this minute displacement is not to completely remove the tool from the current cutting surface or retract it to a safe distance, but rather to actively release the additional mechanical strain caused by the interference fit or continuous loading between the tool and the material through a very limited, precisely controlled positional retraction. Ideally, this tiny displacement is sufficient to bring the real-time monitored tool workload back from a dangerous state exceeding the critical upper limit to a safe range, thereby immediately eliminating the risk of overload. Simultaneously, it maximizes the stability of the formed cutting interface or peeling state, creating conditions for subsequent feed and peeling.
[0052] The micro-retraction distance defined in this invention is designed with the philosophy of "minimal necessary intervention." It aims to achieve immediate improvement in load conditions with minimal positional change. This minimizes the interference of protective intervention on the ongoing peeling process. After retraction, the tool tip remains very close to, or even almost completely stationary near, the original cutting depth, allowing for seamless continuation of the planned feed peeling operation once the load returns to normal. This protective corrective action, precise to the millimeter level and geared towards maintaining operational continuity, differs significantly in both its working philosophy and practical effect from the "reset" action in existing technologies, which often results in operational interruption or interface damage after protection. It allows the micro-force protection function to be more smoothly integrated into the continuous peeling process.
[0053] In a preferred embodiment, the remote management center of the convenient ribbon optical cable stripping device further stores a tool wear compensation parameter table, which defines the mapping relationship between the cumulative number of tool uses and the compensation coefficient. The remote management center is configured to perform the following operations: receive the cumulative number of tool uses uploaded by the wireless communication module of the device body; query the tool wear compensation parameter table to obtain the corresponding compensation coefficient based on the cumulative number of tool uses; and compensate the upper limit of each critical stripping force range according to the compensation coefficient based on the compensation rules.
[0054] In addition to storing standard safety stripping parameter sets for each fiber optic cable model, the remote management center also maintains a tool wear compensation parameter table. This parameter table uses the cumulative number of tool uses as an index, with each range associated with a compensation coefficient greater than zero. For example, in the range of 0 to 100 uses, the compensation coefficient can be 1.0, indicating no compensation; in the range of 101 to 300 uses, the compensation coefficient may be set to 1.15.
[0055] Before each operation or periodically, the equipment's wireless communication module uploads the cumulative number of tool uses as one of its status information messages to the remote management center. Upon receiving the information, which includes the fiber optic cable type and the number of tool uses, the management center first queries the standard precision calibration parameter database to obtain the initial set of safe stripping parameters. Then, based on the received number of tool uses, it looks up the corresponding compensation coefficient in the tool wear compensation parameter table.
[0056] After obtaining this coefficient, the management center processes the key part of the safe peeling parameter set—the upper limit of the critical peeling force range—according to the established compensation rules. The purpose of this processing is to adjust the standard force threshold originally applicable to new tools to a compensated force threshold applicable to tools in the current wear state. This compensated new parameter set will replace or supplement the original standard parameters and will be sent to the field equipment along with the control commands.
[0057] This invention introduces a systematic wear compensation path based on objective data (cumulative usage count). Through predefined coefficient mapping, it transforms the tool's usage history into quantitative adjustments to key control parameters. This allows the protection threshold issued to field equipment to dynamically and proportionally increase according to the actual wear level of the tool. Its core advantage lies in transforming wear management from an uncertain process dependent on operator feel and experience into a predictable and repeatable automated parameter adjustment process. This aims to maintain the continuous effectiveness of micro-force protection throughout the entire tool lifecycle, reducing the probability of protection failure or a decline in user experience due to tool performance degradation.
[0058] In a preferred embodiment, the compensation rule in the convenient ribbon optical cable stripping device is as follows: multiply the compensation coefficient by the upper limit of each standard critical stripping force range to obtain the upper limit of each compensated critical stripping force range.
[0059] Once the management center retrieves the compensation coefficient corresponding to the current cumulative number of times the tool has been used from the tool wear compensation parameter table, it will apply this rule to the upper limit of each critical peeling force range in the safe peeling parameter set.
[0060] The rule is as follows: For each standard critical stripping force range requiring compensation, its upper limit value is directly multiplied by the obtained compensation coefficient. For example, assuming that for a specific optical cable layer, the upper limit of its standard critical stripping force range is 100 Newtons, and the obtained compensation coefficient is 1.2, then the new upper limit value after compensation is 120 Newtons. If the stripping parameter set of this type of optical cable contains critical stripping force ranges for three different layers, then this multiplication operation will be performed on the upper limits of all three ranges one by one. The resulting set of new values constitutes the "wear-compensated critical stripping force range," which is then encapsulated in the issued control command.
[0061] This multiplication rule ensures that the compensation process is linear and proportional. The magnitude of the compensation coefficient directly determines the amplification factor of the standard upper limit. A coefficient of 1.0 means no compensation, while a coefficient greater than 1.0 means that the maximum allowable load threshold is increased proportionally according to the degree of wear. This rule is simple and clear, requiring no complex functions or conditional judgments, making it easy to execute efficiently and reliably in cloud data processing systems.
[0062] The "multiplication" rule defined in this invention transforms wear compensation into a precise and quantifiable mathematical operation. It establishes a direct and transparent linear relationship between the "degree of wear (represented by a coefficient)" and the "parameter adjustment range." This rule eliminates the arbitrariness and uncertainty of compensation behavior. Its advantages are: first, it is easy to understand and implement, both for system developers and process parameter managers; second, it ensures the predictability and consistency of compensation results—tools under the same wear condition will receive the same parameter adjustments regardless of when or where they are used; and finally, it strictly limits compensation to a proportional amplification of the force threshold, focusing on the core objective of maintaining the effectiveness of the protective function, avoiding blind adjustments to other irrelevant parameters (such as depth). This constitutes a clear, stable, and well-defined technical compensation scheme.
[0063] In a preferred embodiment, the convenient ribbon optical cable stripping device further includes a status indicator unit; after receiving a control command from a remote management center, the control module drives the status indicator unit to issue a first prompt signal; when the micro-force protection mode is activated, the control module drives the status indicator unit to issue a second prompt signal that is different from the first prompt signal.
[0064] This unit receives drive signals from the control module and, depending on the different working stages of the device, issues visual, auditory, or tactile cues with clear distinction.
[0065] During the preparation phase, once the control module successfully receives and parses the control commands from the remote management center and confirms that it has acquired the precise stripping parameters for the current optical cable, it will drive the status indicator unit to issue the first prompt signal. This signal is intended to convey to the operator the message that "the equipment is ready, the parameters have been loaded, and safe stripping can begin."
[0066] During the peeling operation, once the control module determines, based on real-time monitoring, that the current cutting depth has reached the precise depth value of the target layer and immediately activates the low-force protection mode, it will immediately drive the status indicator unit to issue a second prompt signal. The second prompt signal must be clearly distinguishable from the first prompt signal in form, and its purpose is to immediately convey to the operator the key status change that "the equipment has entered a high-sensitivity protection state and is monitoring the peeling force."
[0067] With these two preset, differentiated signals, operators can quickly and accurately judge the core operating status of the device without constantly paying attention to complex screen readings or relying on personal guesswork, thereby guiding their subsequent operations.
[0068] This invention establishes a clear status communication channel between the device and the operator by adding a dedicated status indication unit and defining its linkage with the core operating logic. It transforms the key internal logic states of the device (parameter readiness, protection activation) into externally perceptible prompts. This design enhances operational transparency and guidance, enabling operators to perform tasks based on a clear understanding of the device's status. This helps reduce misoperations or underutilization of device functions due to information asymmetry, making human-machine collaboration more efficient and reliable.
[0069] In a preferred embodiment, the status indicator unit of the convenient ribbon optical cable stripping device includes at least two different colored LED indicator lights, wherein the first indication signal is a constantly lit LED of the first color, and the second indication signal is a flashing LED of the second color.
[0070] The status indication unit is specifically implemented as a hardware indicator module. This module typically contains at least two LEDs of different colors, such as a green LED and a red LED, which are mounted on the device body in a location easily visible to the operator. When the device control module confirms receipt of a valid cloud parameter command, it drives the status indication unit to illuminate the LED representing the "ready" state in a specific pattern. For example, it can be set to keep the green LED constantly lit. This stable and continuous light signal clearly indicates to the operator that the device has been loaded with parameters and is in standby mode.
[0071] When the micro-force protection mode is activated during the peeling process, the control module immediately changes the drive signal, and the control status indicator unit switches to a second alert signal mode. This mode must be significantly different from the first mode. A typical implementation is to turn off the green LED while simultaneously driving the red LED to flash at a preset frequency (e.g., 2 to 3 times per second). This light signal, with its simultaneous change in color and dynamic pattern, provides stronger visual attention and status differentiation, effectively and instantly reminding the operator that the equipment has entered a critical, monitoring-required protective phase during operation.
[0072] This invention employs a low-cost, highly reliable, and clearly identifiable hardware solution to achieve clear state differentiation. It utilizes a combination of two dimensions—color (green / red) and dynamic pattern (constant / flashing)—to encode two key system states using only two LEDs. This design maximizes the efficiency and accuracy of state information transmission within limited cost and space constraints. A constant green light and a flashing red light are visually distinct and easily distinguishable even in low light conditions or when only glanced at by the operator.
[0073] This invention provides a specific embodiment of a convenient strip optical cable stripping device.
[0074] The basic physical components of this device and its installation method can all be achieved using existing technologies. The device body is a conventional handheld or benchtop tool housing, used to house and support the various functional components. The tool adjustment mechanism can employ a micro-feed mechanism with a precision threaded knob and linear guide rail to achieve fine adjustment of the cutting depth. The fixed part of the displacement sensor (such as a miniature linear displacement sensor) is mounted on the device body, and its measuring head is connected to the moving part of the tool for real-time measurement of the tool's cutting depth. The pressure sensor (such as a strain gauge force sensor) is integrated into the force path between the tool assembly and the device body for real-time sensing of the tool's working load.
[0075] One specific implementation of the tool adjustment mechanism is as follows: The tool adjustment mechanism uses a small two-phase hybrid stepper motor as its power source. This motor is connected to a precision ball screw via a set of miniature planetary gear reducers. The ball screw nut is fixed to a movable tool holder slider. When the control module sends a pulse signal to the stepper motor driver, the motor rotates accordingly. After torque amplification by the reducer, the motor drives the ball screw to rotate, thus converting the rotary motion into high-precision, low-friction linear motion of the nut and the tool holder slider. The tool is mounted at the front end of the tool holder.
[0076] An incremental encoder is integrated at the tail of the stepper motor. Simultaneously, a magnetic scale reading head is mounted on the tool holder slider, and the matching magnetic scale is fixed to the base along the direction of movement. The encoder signal is used for commutation control and step loss detection of the motor, while the magnetic scale provides direct, high-resolution actual position feedback. The control module reads the magnetic scale signal in real time and compares it with the target position value (precise depth value or real-time control command from the cloud). It then adjusts the pulse frequency and direction sent to the stepper motor using a PID control algorithm, forming a fully closed-loop position control system.
[0077] The remote management center is deployed on a cloud server and has established a precise calibration parameter database. This database was established through standard laboratory procedures: for optical cable samples of different models, layered dissection and micro-force testing were performed using metrology equipment to systematically record the precise depth values and critical stripping force ranges corresponding to the safe stripping of each key structural interface (especially the interface between the outer sheath and the loose tube, the interface between the loose tube and the fiber ribbon, and the interface of the fiber coating).
[0078] The on-site operation process is as follows: Parameter Acquisition and Presetting: The operator uploads the fiber optic cable model to the remote management center via a wireless communication module by scanning a barcode or entering the information. The management center queries the database to obtain the matching set of safety stripping parameters and sends it to the equipment. After the control module parses the command, it can drive the actuator to automatically adjust the cutter and limit device to the preset position, while the status indicator unit (such as a solid green LED) indicates that it is ready.
[0079] Peeling and Monitoring: The operator begins peeling. Displacement sensors provide real-time feedback on the cutting depth, and pressure sensors provide real-time feedback on the tool's working load.
[0080] Layered protection: The control module continuously compares the current depth with the precise depth values of each layer sent from the cloud. When the depth reaches the calibration value of a certain target layer (such as the fiber coating layer), the micro-force protection mode is automatically activated.
[0081] Micro-force protection logic: This mode employs a tiered response strategy. First, when the working load reaches a value within the range of 105% to 110% of the upper limit of the critical peel force range for that layer (e.g., 106%), a pause-hold command is triggered. The tool stops feeding and maintains the current state for 0.3 to 0.8 seconds (e.g., 0.5 seconds). During this period, if the load naturally falls back to a safe range, the protection is released, and operation continues. If the load is still higher than the upper limit after the holding period ends, a micro-retraction command is triggered, controlling the tool to retract 0.02 to 0.1 mm (e.g., 0.05 mm) to release stress.
[0082] Wear compensation (optional): The remote management center can also query the pre-stored wear compensation parameter table to obtain the compensation coefficient (e.g., 1.15) based on the cumulative number of tool uses reported by the equipment, and multiply the coefficient by the upper limit of the standard critical peel force range to obtain the compensated threshold before issuing it to adapt to the tool wear status.
[0083] Status indication: When the micro-force protection mode is activated, the status indication unit switches to the second prompt signal (such as a flashing red LED) to intuitively remind the operator.
[0084] In summary, this invention combines cloud-based precise parameter calibration, real-time multi-sensor monitoring, and hierarchical intelligent control logic to enable traditional peeling tools to perform operations based on objective parameters and to proactively and meticulously protect fragile structures, thereby improving the consistency and reliability of peeling quality.

Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and examples shown and described herein.
