Description

Technical Field

[0001] This invention relates to the field of wire processing control technology, and in particular to a wire stripping control method, apparatus, equipment and medium based on conductive feedback. Background Technology

[0002] Mid-stripping of wires refers to the process of removing the outer sheath of a wire in its middle section without cutting the wire itself. It is a common procedure in wire harness processing. Existing mid-stripping methods are mainly divided into manual and automatic methods. Manual methods typically use wire strippers or utility knives to make circumferential and longitudinal cuts to the wire sheath. This method heavily relies on the operator's experience to control the cutting depth, and is prone to damaging the core wire due to excessive cutting. It also results in poor processing consistency and is difficult to meet the needs of mass production. Automatic methods use fully automated mid-stripping equipment that uses position sensors or vision systems to detect the core wire position and control the cutting depth. While this improves processing accuracy and efficiency, the detection system is complex and costly.

[0003] In existing automated stripping equipment, there are various detection schemes for controlling the cutting depth. For example, although the detection scheme based on capacitive sensors has high accuracy, it requires complex signal processing circuits and has insufficient applicability to core wire materials with low conductivity.

Based on the initial state configuration, drive the double-blade assembly downward to cut into the outer sheath of the target wire, and detect the continuity state between the double-blade assembly and the core wire of the target wire to obtain the continuity detection result; When the continuity detection result indicates continuity, the switching mechanism is triggered to switch the pressing state to the rotating state, and the dual-blade assembly is controlled to retract a preset retraction distance to obtain a rotation ready result; Based on the rotation readiness result, the drive motor rotates forward and is switched to the circumferential cutting state via the transmission mechanism to drive the double-blade assembly to rotate around the target wire once to complete the circumferential cutting, thus obtaining the circumferential cutting completion result; Based on the completion result of the circumferential cutting, the motor is driven to reverse and switched to the longitudinal cutting state via the transmission mechanism to drive the longitudinal cutting blade to move according to the middle peeling length to complete the longitudinal cutting, thereby obtaining the longitudinal cutting completion result; Based on the longitudinal cutting completion result, the motor is stopped and the switching mechanism is reset to the pressing position to wait for the next stripping operation, thus obtaining a reset standby state.

[0006] Secondly, embodiments of the present invention provide a wire stripping control device based on conductive feedback, comprising: The state configuration unit is used to control the dual-blade assembly and the longitudinal cutter to move to the initial position, and to adjust the distance between the two cutters in the dual-blade assembly according to the preset peeling length to obtain the initial state configuration; A continuity detection unit is configured to drive the double-blade assembly downward to cut into the outer sheath of the target wire based on the initial state configuration, and detect the continuity state between the double-blade assembly and the core wire of the target wire to obtain a continuity detection result.

[0007] Thirdly, embodiments of the present invention provide a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the wire stripping control method based on conductive feedback of the first aspect.

[0008] Fourthly, embodiments of the present invention provide a computer-readable storage medium, wherein a computer program is stored on the computer-readable storage medium, and when the computer program is executed by a processor, it implements the wire stripping control method based on conductive feedback of the first aspect.

[0009] This invention provides a wire stripping control method based on conductivity feedback, including controlling a double-blade assembly and a longitudinal cutter to move to an initial position, and adjusting the spacing between the two cutters in the double-blade assembly according to a preset stripping length to obtain an initial configuration; based on the initial configuration, driving the double-blade assembly downward to cut into the outer sheath of the target wire, and detecting the continuity between the double-blade assembly and the core wire of the target wire to obtain a continuity detection result; when the continuity detection result indicates continuity, triggering a switching mechanism to switch the pressing state to the rotating state, and controlling the double-blade assembly to retract a preset position.

[0018] Please see below. Figure 1 , Figure 1 The flowchart of a wire stripping control method based on conductive feedback provided in an embodiment of the present invention specifically includes steps S101 to S106.

[0019] S101. Control the double-blade assembly and control the longitudinal cutter to move to the initial position, and adjust the distance between the two cutters in the double-blade assembly according to the preset peeling length to obtain the initial state configuration; S102. Based on the initial state configuration, drive the double-blade assembly to cut downward into the outer sheath of the target wire, and detect the continuity state between the double-blade assembly and the core wire of the target wire to obtain the continuity detection result; S103. When the continuity detection result indicates continuity, the switching mechanism is triggered to switch the pressing state to the rotating state, and the double-blade assembly is controlled to retract a preset retraction distance to obtain a rotation ready result. S104. Based on the rotation ready result, drive the motor to rotate forward and switch to the circumferential cutting state through the transmission mechanism to drive the double-blade assembly to rotate around the target wire once to complete the circumferential cutting and obtain the circumferential cutting completion result; S105. Based on the completion result of the circumferential cutting, drive the motor to reverse and switch to the longitudinal cutting state through the transmission mechanism to drive the longitudinal cutting blade to move according to the middle peeling length to complete the longitudinal cutting, thereby obtaining the completion result of the longitudinal cutting. S106. Based on the longitudinal cutting completion result, control the motor to stop and reset the switching mechanism to the pressing position to wait for the next stripping operation, thus obtaining a reset standby state.

[0020] In step S101, before performing the mid-peeling operation, the double-blade assembly and the longitudinal cutter are first controlled to move to their respective initial positions, and the distance between the two cutters in the double-blade assembly is adjusted according to the preset mid-peeling length, so that each component is in a ready state before the mid-peeling operation, and the initial state configuration is obtained.

[0021] In one embodiment, step S101 includes: Control the first and second blades of the dual-blade assembly to switch to the initial upper-level state, and make both the first and second blades disconnect from the target wire to obtain dual-blade upper-level data; Control the longitudinal cutter to move to an initial position corresponding to the position of the first cutter, and put the longitudinal cutter in an initial state to be moved, thereby obtaining the initial data of the longitudinal cutter; Adjust the distance between the first blade and the second blade according to the preset peeling length to obtain the blade spacing configuration data; Set the preset linkage mechanism to a manually press-down state or set the preset grooved wheel to a press-down station, and switch to the press-down ready-to-trigger state to obtain the press-down station state; The initial state configuration is obtained by combining the upper data of the dual blades, the initial data of the longitudinal cutting blade, the configuration data of the dual blade spacing, and the state of the pressing station.

[0022] In this embodiment, the first and second blades of the dual-blade assembly are switched to the initial upper position, and both blades are detached from the target wire, thus obtaining dual-blade upper position data. The dual-blade assembly refers to a cutting tool assembly used to cut into the outer sheath of the target wire. This assembly includes two cutting blades, a first blade and a second blade, spaced apart along the axial direction of the wire. During the subsequent downward pressing process, the first and second blades simultaneously cut into the outer sheath of the target wire, forming two annular cuts on the sheath. The initial upper position means that both blades are in a raised position away from the target wire, i.e., the blades of both blades are not in contact with the outer sheath of the target wire, thus maintaining sufficient distance between the dual-blade assembly and the target wire, allowing the operator to smoothly place the target wire to be stripped into the blades. By switching both blades to the upper position detached from the target wire, dual-blade upper position data is obtained. This data indicates that the dual-blade assembly is in a safe initial position, providing the starting conditions for the subsequent downward cutting operation.

[0023] Furthermore, the longitudinal cutter is controlled to move to an initial position corresponding to the first cutter position, and is placed in an initial state ready to move, thus obtaining the initial data for the longitudinal cutter. The longitudinal cutter is an independent tool used to longitudinally cut the outer sheath along the axial direction of the wire. In subsequent longitudinal cutting steps, it will move along the wire axis from the first cutter position to the second cutter position to form a longitudinal slit between two annular cuts, thereby allowing the cut outer sheath segment to be peeled off. Therefore, in the initial state, the longitudinal cutter needs to be pre-aligned to the position corresponding to the first cutter in the axial direction of the wire, placing the longitudinal cutter in an initial state ready to move, ensuring that the starting point of the subsequent longitudinal cutting operation accurately corresponds to the position of the annular cut formed by the first cutter. Through the above control, the initial data for the longitudinal cutter can be obtained. This initial data indicates that the longitudinal cutter is in the correct starting position, ready for subsequent longitudinal cutting actions.

[0024] Furthermore, the distance between the first and second blades is adjusted according to the preset stripping length to obtain the double-blade spacing configuration data. The stripping length refers to the axial length of the middle section of the target wire from which the outer sheath needs to be removed; this length is preset according to actual processing requirements. The distance between the first and second blades directly determines the stripping length; that is, the axial distance between the two blades is equal to the length of the outer sheath to be removed. In actual operation, the relative position of the first and second blades can be adjusted using a handwheel on the equipment to ensure that the distance between the two blades matches the preset stripping length. This distance can be adjusted from 3mm to 20mm to accommodate the stripping processing requirements of wires of different specifications. For example, when the preset stripping length is 10mm, the distance between the first and second blades is adjusted to 10mm using the handwheel. This distance adjustment yields the double-blade spacing configuration data, which indicates that the two blades of the double-blade assembly have completed the spacing setting according to the preset stripping length.

[0025] Furthermore, the preset linkage mechanism is set to a manually press-down state, or the preset grooved wheel is set to a press-down position and switched to a press-down ready-to-trigger state to obtain the press-down position state. Since the wire stripping control method based on conductive feedback in this application is applicable to both handheld and benchtop wire stripping equipment, the press-down drive method differs depending on the equipment type. For handheld wire stripping equipment, the linkage mechanism refers to the transmission structure that converts the operator's trigger action into the press-down movement of the double-blade assembly. Setting the linkage mechanism to a manually press-down state means that the linkage mechanism is in a ready position where the operator can push the double-blade assembly downwards by pulling the trigger. For benchtop wire stripping equipment, the grooved wheel refers to the transmission mechanism that realizes multi-station cyclic indexing. This grooved wheel sequentially switches each functional station to the working position through indexing. Setting the grooved wheel to a press-down position means that the grooved wheel is indexed to the corresponding press-down cutting position, so that the equipment is in a ready-to-trigger state to perform press-down cutting at any time. The pressing station status can be obtained through the above settings. This pressing station status indicates that the pressing drive mechanism of the equipment has been configured and can trigger the pressing and cutting action of the double blade assembly at any time.

[0026] Finally, the upper-level data of the dual blades, the initial data of the longitudinal cutter, the configuration data of the dual blade spacing, and the status of the pressing station are combined to obtain the initial state configuration. This initial state configuration indicates that all functional components of the stripping equipment have completed initialization settings, that is, the dual blade assembly is in the upper position and the spacing between the two cutters has been adjusted according to the stripping length, the longitudinal cutter has been aligned to the initial position of the first blade, and the pressing drive mechanism is in a triggerable ready state. The equipment as a whole has all the conditions to perform the stripping operation and can enter the subsequent pressing cutting and conduction detection stage of step S102.

[0027] In step S102, based on the above initial state configuration, the double-blade assembly is driven to move downward to cut into the outer sheath of the target wire. During the process of the double-blade assembly gradually cutting into the outer sheath, the continuity state between the double-blade assembly and the core wire of the target wire is detected in real time to obtain the continuity detection result.

[0028] In one embodiment, step S102 includes: Based on the initial state configuration, drive the dual-blade assembly to move downwards to cut into the outer sheath of the target wire, thus obtaining a downward cutting state; A constant detection current is applied between the double-blade assembly and the core wire of the target wire through a constant current source detection circuit to obtain a detection current loop; In the downward cutting state, the resistance value between the double-blade assembly and the core wire of the target wire is collected in real time according to the detection current loop to obtain real-time resistance data; The real-time resistance data is filtered out of mechanical jitter by an RC filter circuit to obtain a jitter-reduced resistance signal; When the resistance value corresponding to the debounce resistor signal is less than a preset value, it is determined to be in a conducting state, and a conducting detection result is obtained.

[0029] In this embodiment, the dual-blade assembly is driven downwards based on the initial state configuration to cut into the outer sheath of the target wire, thus achieving a downward cutting state. Specifically, after the initial state configuration is completed, the first and second blades of the dual-blade assembly are in the initial upper position, and the target wire has been placed between the blades. At this time, a downward action is triggered, driving the dual-blade assembly to move downwards in a direction perpendicular to the wire's axial direction, with the first and second blades simultaneously cutting into the outer sheath of the target wire. As the dual-blade assembly continues to press downwards, the two blades gradually penetrate the outer sheath and continuously approach the internal core wire. For example, for a PVC insulated wire with an outer sheath thickness of 2mm, the dual-blade assembly needs to cut down approximately 2mm from the outer surface of the sheath to reach the core wire. During the process of the dual-blade assembly continuously moving downwards and gradually cutting into the outer sheath, it enters the downward cutting state. This downward cutting state indicates that the dual-blade assembly is in the dynamic process of cutting the outer sheath downwards, providing conditions for synchronously performing continuity detection.

[0030] Furthermore, a constant detection current is applied between the double-blade assembly and the core wire of the target wire using a constant current source detection circuit, thus forming a detection current loop. The constant current source detection circuit is a detection circuit capable of outputting a constant current. This circuit continuously applies a stable, small current as a detection signal between the double-blade assembly and the core wire of the target wire. The magnitude of the constant detection current is set within the range of 0.1mA to 1mA, for example, 0.5mA. The reason for using a constant current source as the excitation method for the detection circuit is that the constant small current will not cause electrolytic corrosion or thermal damage to the surface of the core wire when the double-blade assembly contacts it, thereby ensuring the safety of the detection process. When the constant current source detection circuit is working, the detection current is output from one end of the constant current source, conducted through the blade body of the double-blade assembly to the blade edge, forming a detection path between the blade edge of the double-blade assembly and the core wire of the target wire, and then flows back through the core wire to the other end of the constant current source, thus forming a complete detection current loop. Before the double-blade assembly cuts through the outer sheath and contacts the core wire, there is no conductive path between the blade and the core wire because the outer sheath material is an insulator. Therefore, the detection current loop is open, and no current flows through it. As the double-blade assembly continues to cut downwards, once the blade penetrates the outer sheath and contacts the core wire, the detection current loop is activated, and a constant detection current begins to flow through it, thus establishing an effective detection current loop.

[0031] Furthermore, during the downward cutting state, the resistance value between the double-blade assembly and the core wire of the target wire is collected in real time through the detection current loop to obtain real-time resistance data. Throughout the entire process of the double-blade assembly continuously cutting downwards into the outer sheath, the constant current source detection circuit continuously collects the resistance value between the blade of the double-blade assembly and the core wire through the detection current loop. Since the detection current output by the constant current source remains constant, according to Ohm's law, the voltage value in the loop is directly proportional to the resistance value between the double-blade assembly and the core wire. Therefore, the change in resistance value can be obtained in real time by detecting the voltage change across the detection loop. When the blade of the double-blade assembly is still moving downwards within the outer sheath and has not yet contacted the core wire, the resistance value between the double-blade assembly and the core wire exhibits an extremely high value, characteristic of an open circuit, due to the obstruction of the insulating outer sheath. When the blade of the double-blade assembly just penetrates the outer sheath and contacts the surface of the core wire, a conductive contact is formed between the blade and the core wire, and the resistance value decreases sharply from the open circuit state, for example, decreasing to approximately 5kΩ. The specific value depends on the contact area and contact pressure between the blade and the core wire. The detection circuit continuously collects the resistance value to obtain real-time resistance data, which reflects the resistance change process between the double-blade assembly and the core wire from insulation isolation to conductive contact.

[0032] Furthermore, the real-time resistance data is filtered through an RC filter circuit to remove mechanical jitter, resulting in a de-jittering resistance signal. The RC filter circuit is a low-pass filter composed of a series-connected resistive and capacitive element, connected in series in the detection loop to smooth out high-frequency fluctuations in the real-time resistance data. During the downward cutting of the outer sheath by the dual-blade assembly, transient pulse signals generated by mechanical jitter are mixed into the acquired real-time resistance data due to factors such as gaps and vibrations between mechanical transmission components and uneven contact between the blade and the outer sheath material. These transient pulse signals may cause false triggering of the detection circuit, incorrectly classifying a state where the core wire has not yet been truly contacted as conductive. The time constant of the RC filter circuit is set to 10ms to 20ms, for example, 15ms. This time constant effectively filters out transient pulse signals with durations shorter than this time constant, while retaining the continuous resistance change signal generated when the core wire is truly in contact. After filtering by the RC filter circuit, the short-term fluctuations caused by mechanical jitter in the real-time resistance data are eliminated, resulting in a stable and reliable de-jittering resistance signal.

[0033] Finally, when the resistance value corresponding to the de-jitter resistor signal is less than the preset value, it is determined to be in a conducting state, and a continuity detection result is obtained. The preset value refers to the resistance threshold used to determine whether an effective conductive contact has been formed between the double-blade assembly and the core wire. This threshold is preset according to the actual detection accuracy requirements, for example, set to 10kΩ. During the detection process, the de-jitter resistor signal processed by the RC filter circuit is compared with the preset value. When the resistance value corresponding to the de-jitter resistor signal is greater than or equal to the preset value, it indicates that the blade of the double-blade assembly has not yet penetrated the outer sheath or has not yet formed an effective contact with the core wire. At this time, it is determined to be in a non-conductive state, and the double-blade assembly continues to move downwards. When the resistance value corresponding to the de-jitter resistor signal is less than the preset value, it indicates that the blade of the double-blade assembly has penetrated the outer sheath and established a reliable conductive contact path with the core wire. At this time, it is determined to be in a conducting state, and a continuity detection result is obtained. This continuity detection result indicates that the cutting depth of the double-blade assembly has reached the surface of the core wire. Without needing to preset the cutting depth parameters according to the wire specifications, the actual thickness of the outer sheath can be adaptively determined through conductive feedback, thus providing an accurate trigger reference for the action switching in the subsequent step S103.

[0034] In step S103, when the continuity detection result indicates that a connection has been formed between the double-blade assembly and the core wire, the switching mechanism is triggered to switch the current pressing state to the rotation state, and at the same time, the double-blade assembly is controlled to retract a preset retraction distance to obtain the rotation ready result.

[0035] In one embodiment, step S103 includes: When the continuity detection result indicates continuity, the thyristor is triggered to conduct through the continuity signal to drive the electromagnet to generate an attraction force, thus forming a switching driving force. The switching driving force controls the shift fork of the switching mechanism to disconnect the pressing link and connect to the rotating link, or triggers the grooved wheel brake to pause the rotation, thus obtaining the transmission switching state; In a handheld device, the motor is controlled to reverse by a preset degree, converting the rotation into linear retraction, thus obtaining the handheld retraction amount; In the desktop device, the driven component is pulled to force the dual-blade assembly to retract, thus obtaining the desktop retraction amount; Based on the transmission switching state, the dual-blade assembly is retracted to a preset distance according to the handheld retraction amount or the desktop retraction amount, to obtain a rotation-ready result.

[0036] In this embodiment, when the continuity detection result indicates continuity, a continuity signal triggers the thyristor to conduct, driving the electromagnet to generate an attractive force, thus forming a switching driving force. Specifically, the continuity signal refers to the voltage jump signal output by the detection circuit in step S102 when the resistance value corresponding to the debounce resistor signal is less than a preset value, indicating a continuity state. A thyristor is a controllable semiconductor switching device. Before the continuity signal is triggered, the thyristor is in the off state, and no current flows through its drive circuit. When the continuity signal reaches the control electrode of the thyristor, the thyristor switches from the off state to the on state, thereby connecting the drive circuit. An electromagnet is an actuator that generates electromagnetic attraction through current, and it is connected in series with the thyristor in the same drive circuit. When the thyristor conducts, the drive circuit is connected, current flows through the coil of the electromagnet, and the electromagnet generates an attractive force. This attractive force forms the switching driving force used to drive the subsequent switching mechanism to switch its operating state.

[0037] Furthermore, by switching the driving force, the shift fork of the switching mechanism disconnects the pressing link and connects to the rotating link, or triggers the grooved wheel brake to pause rotation, thus obtaining the transmission switching state. The switching mechanism refers to the assembly used to switch the transmission path between different action stages of the stripping operation, and its implementation varies depending on the type of equipment. For handheld stripping equipment, the switching mechanism adopts a shift fork-type switching structure. The shift fork is a fork-shaped mechanical element that can slide between two positions. One end is driven by the attraction force of an electromagnet, and the other end corresponds to the two connection positions of the pressing link and the rotating link, respectively. The pressing link is the transmission link that transmits the operator's trigger action to the double-blade assembly to drive it downward. The rotating link is the transmission link that transmits the rotational power of the motor to the double-blade assembly to drive it to rotate around the target wire. During the pressing and cutting process in step S102, the shift fork is in the first position, connected to the pressing link, allowing the operator to push the double-blade assembly downward by triggering the action. When the electromagnet is energized and generates a switching driving force, it pulls the shift fork from the first position to the second position. During this process, the shift fork disconnects from the downward connecting rod and switches to the position connected to the rotating connecting rod, thereby switching the transmission path from the downward channel to the rotating channel. For benchtop stripping equipment, the switching mechanism adopts a grooved wheel brake structure. The grooved wheel brake is an electromagnetic braking device installed on the grooved wheel drive shaft. When the electromagnet is energized and generates a switching driving force, this driving force triggers the grooved wheel brake to operate, clamping the grooved wheel drive shaft and stopping its rotation, thus pausing the indexing movement of the grooved wheel. Through the above-mentioned shift fork switching or the grooved wheel brake pausing the rotation, the transmission switching state is obtained. This transmission switching state indicates that the transmission system of the equipment has switched from the downward state to the rotating state, and the double-blade assembly no longer continues to move downward.

[0038] Furthermore, in the handheld device, the motor is controlled to reverse by a preset degree, converting rotation into linear retraction, thus obtaining the handheld retraction amount. Specifically, in the handheld stripping device, after the transmission switching state is established, the motor controller receives a trigger signal and controls the motor to briefly reverse. The preset degree of reversal is set between 10 and 30 degrees, for example, 20 degrees. The rotational motion generated by the motor reversal is converted into linear retraction motion in the vertical direction through mechanical conversion structures such as cam profiles or lead screw drives. That is, the rotational displacement of the motor is converted into the linear displacement of the double-blade assembly in the direction away from the core wire. The linear retraction displacement obtained through the above conversion is the handheld retraction amount, which corresponds to the actual distance the double-blade assembly retracts upward from the position of contact with the core wire in the handheld device.

[0039] Furthermore, in the benchtop stripper, the driven element is pulled to force the double-blade assembly to retract, thus obtaining the benchtop retraction amount. The driven element refers to the transmission and following component connected to the double-blade assembly in the benchtop stripper; the up-and-down movement of the double-blade assembly is driven by the displacement of the driven element. In the benchtop stripper, after the grooved wheel brake pauses rotation, causing the double-blade assembly to stop pressing down, the driven element is directly pulled by an independent actuator such as an electromagnet or cylinder, causing the driven element to force the double-blade assembly to retract in a direction away from the core wire. Unlike handheld devices that indirectly achieve retraction through motor reversal, the benchtop device directly acts on the driven element through an independent actuator, achieving rapid forced retraction of the double-blade assembly. The retraction displacement generated by pulling the driven element is the benchtop retraction amount, which corresponds to the actual distance the double-blade assembly retracts upward from its contact position with the core wire in the benchtop device.

[0040] Finally, based on the transmission switching state, the dual-blade assembly is retracted to a preset distance according to the hand-held or benchtop retraction amount, resulting in a rotation-ready state. The preset distance refers to a set distance ΔH from the point where the blade contacts the core wire, moving away from the core wire. This preset distance ranges from 0.1mm to 0.5mm, for example, set to 0.2mm. Depending on the equipment type, the hand-held or benchtop retraction amount controls the precise retraction of the dual-blade assembly to this preset distance. The purpose of retracting the preset distance is to maintain a small safety gap between the blades of the dual-blade assembly and the surface of the core wire. This gap ensures that the blades will not scratch or damage the core wire during the subsequent circumferential cutting process, while also ensuring that the blades remain embedded in the outer sheath to maintain effective cutting. Once the dual-blade assembly has retracted the preset distance, a rotation-ready state is obtained. This state indicates that the transmission path has switched to the rotation channel and the dual-blade assembly has retracted to a safe position, making the equipment ready to execute the subsequent step S104 circumferential cutting operation.

[0041] In step S104, the drive motor rotates forward according to the rotation ready result and is switched to the ring cutting state through the transmission mechanism to drive the double blade assembly to rotate around the target wire once to complete the ring cutting and obtain the ring cutting completion result.

[0042] In one embodiment, step S104 includes: Based on the rotation readiness result, the motor is driven to rotate forward to obtain a forward rotation drive signal; Based on the forward rotation drive signal, the first one-way bearing of the transmission mechanism locks the rotating transmission chain, and during the forward rotation, the second one-way bearing of the transmission mechanism is controlled to rotate freely so that the longitudinal cutting transmission chain remains stationary and enters the circumferential cutting state; In the circumferential cutting state, the dual-blade assembly is controlled to rotate around the target wire once to obtain the circumferential cutting result.

[0043] In this embodiment, the motor is driven to rotate forward based on the rotation readiness result, thus obtaining a forward rotation drive signal. Specifically, after the transmission path has been switched to the rotation channel and the double-blade assembly has retracted to a preset distance in step S103, the rotation readiness result indicates that the device is ready to perform the circumferential cutting action. At this time, the motor controller sends a forward rotation control command to the motor according to the rotation readiness result, driving the motor to start running in the forward rotation direction. The forward rotation power output by the motor after startup forms the forward rotation drive signal. This forward rotation drive signal serves as the input signal for subsequent power distribution and transmission chain selection in the transmission mechanism, determining the working state of each transmission path in the transmission mechanism.

[0044] Furthermore, based on the forward rotation drive signal, the first one-way bearing of the transmission mechanism locks the rotary transmission chain, and during forward rotation, the second one-way bearing of the transmission mechanism is controlled to idle, so that the longitudinal cutting transmission chain remains stationary and enters the circumferential cutting state. Here, the transmission mechanism refers to the mechanical transmission assembly located between the motor and each actuator, used to distribute the motor's rotational power to different action execution paths. This transmission mechanism includes two independent transmission paths: a rotary transmission chain and a longitudinal cutting transmission chain. The rotary transmission chain refers to the transmission path from the motor via the transmission mechanism that ultimately transmits rotational power to the double-blade assembly to drive the double-blade assembly to rotate around the target wire. The longitudinal cutting transmission chain refers to the transmission path from the motor via the transmission mechanism that ultimately transmits power to the longitudinal cutting blade to drive the longitudinal cutting blade to move along the wire axial direction. The first one-way bearing is a one-way clutch bearing installed in the rotary transmission chain, which has the one-way transmission characteristic of locking transmission in one rotational direction and freely idling in the opposite direction. The second one-way bearing is a one-way clutch bearing installed in the longitudinal cutting transmission chain, whose one-way transmission direction is opposite to that of the first one-way bearing. When the motor rotates forward, the forward rotational power carried by the forward drive signal is transmitted to the transmission mechanism. The first one-way bearing is locked in the forward rotation direction, with a rigid connection between its inner and outer rings. This ensures that the forward rotational power of the motor is completely transmitted to the subsequent links of the rotary transmission chain, keeping the rotary transmission chain in an effective working state. Simultaneously, the second one-way bearing idles in the forward rotation direction, with no torque transmitted between its inner and outer rings. The inner ring rotates with the motor while the outer ring remains stationary. This prevents the longitudinal transmission chain from receiving any rotational power during the forward rotation of the motor, keeping the entire longitudinal transmission chain stationary. Through the coordinated action of the first one-way bearing locking the rotary transmission chain and the second one-way bearing idles to keep the longitudinal transmission chain stationary, selective power transmission is achieved where a single motor drives only the rotary transmission chain in the forward rotation direction without affecting the longitudinal transmission chain. The equipment thus enters the circumferential cutting state. This circumferential cutting state indicates that the forward rotational power of the motor has been precisely distributed to the rotary drive chain, while the longitudinal cutting drive chain is in a completely static and isolated state. The dual-blade assembly can perform circumferential rotational action under the forward drive of the motor, while the longitudinal cutting blade will not move at all.

[0045] Finally, in the circumferential cutting state, the dual-blade assembly is controlled to rotate one revolution around the target wire, resulting in a completed circumferential cut. Specifically, after entering the circumferential cutting state, the forward rotational power of the motor is continuously transmitted to the dual-blade assembly through the rotational transmission chain locked by the first one-way bearing, driving the dual-blade assembly to rotate around the axis of the target wire. During the rotation, the first and second blades of the dual-blade assembly always maintain the cutting depth after retracting the preset distance in step S103, that is, the blade is embedded in the outer sheath but a safe gap is maintained between it and the surface of the core wire. As the dual-blade assembly rotates around the target wire, the first and second blades continuously cut the outer sheath along the circumference of the target wire. When the dual-blade assembly completes a full revolution around the target wire, i.e., a 360-degree rotation, the first and second blades each form a complete closed annular cut on the outer sheath. The distance between the two annular cuts is the preset stripping length, thus completing the circumferential cutting operation. After the circumferential cutting is completed, the motor stops rotating forward, and the circumferential cutting result is obtained. This result indicates that two complete annular cuts have been formed on the outer sheath of the target wire, and the outer sheath of the stripped area has been completely cut off in the circumferential direction, which provides the conditions for longitudinal cutting between the two annular cuts by a longitudinal cutter in the subsequent step S105.

[0046] In step S105, the drive motor reverses according to the circumferential cutting result and switches to longitudinal cutting state through the transmission mechanism to drive the longitudinal cutting blade to move according to the preset peeling length to complete the longitudinal cutting and obtain the longitudinal cutting result.

[0047] In one embodiment, step S105 includes: Based on the completion result of the circumferential cutting, the motor is controlled to reverse, and a reverse drive command is sent to the longitudinal cutting transmission chain to obtain a reverse drive signal; Based on the reversing drive signal, the longitudinal cutting transmission chain is locked by the second one-way bearing of the transmission mechanism, and the first one-way bearing of the transmission mechanism is controlled to rotate freely during the reversing process, so that the rotating transmission chain remains stationary and enters the longitudinal cutting state; In the longitudinal cutting state, the longitudinal cutting blade is controlled to move from the first blade position of the double blade assembly to the second blade position of the double blade assembly, and then the moving distance of the longitudinal cutting blade is controlled to be the same as the peeling length to complete the longitudinal cutting and obtain the longitudinal cutting result.

[0048] In this embodiment, the motor is controlled to reverse based on the completion result of the circumferential cutting, and a reverse drive command is sent to the longitudinal cutting transmission chain, resulting in a reverse drive signal. Specifically, after the double-blade assembly completes the circumferential cutting by rotating around the target wire once in step S104, two complete closed annular cuts are formed on the outer sheath of the target wire, at which point the motor stops rotating forward. Subsequently, the motor controller sends a reverse rotation control command to the motor based on the completion result of the circumferential cutting, driving the motor to switch from the forward direction to the reverse direction and start running. After the motor reverses, the reverse rotation power is transmitted to the input end of the longitudinal cutting transmission chain via the transmission mechanism, that is, a reverse drive command is sent to the longitudinal cutting transmission chain. The reverse rotation power carried by this reverse drive command forms the reverse drive signal, which serves as the basis for switching the power distribution among the one-way bearings in the transmission mechanism, and is used to switch the power output of the motor from the rotational transmission chain to the longitudinal cutting transmission chain.

[0049] Furthermore, based on the reverse drive signal, the second one-way bearing of the transmission mechanism locks the longitudinal cutting transmission chain, and during the reverse process, the first one-way bearing of the transmission mechanism is controlled to idle, so that the rotating transmission chain remains stationary and enters the longitudinal cutting state. Specifically, when the motor switches from the forward direction to the reverse direction, the working state of the two one-way bearings in the transmission mechanism changes accordingly. The second one-way bearing is in an idle state during the forward rotation of the motor in step S104 and does not transmit any power to the longitudinal cutting transmission chain. When the motor switches to the reverse direction, the reverse rotational power carried by the reverse drive signal acts on the second one-way bearing. The second one-way bearing switches from the idle state to the locked state in the reverse direction, and a rigid connection is formed between its inner and outer rings, thereby completely transmitting the reverse rotational power of the motor to the subsequent links of the longitudinal cutting transmission chain, so that the longitudinal cutting transmission chain is in an effective working state. Meanwhile, the first one-way bearing is locked during the forward rotation of the motor in step S104 to drive the rotary transmission chain. When the motor switches to the reverse direction, the first one-way bearing switches from the locked state to the idle state in the reverse direction, and its inner and outer rings no longer transmit torque. This ensures that the rotary transmission chain does not receive any rotational power during the motor's reverse rotation, and the entire rotary transmission chain remains stationary. The double-blade assembly no longer generates rotational motion around the target wire. Through the coordinated action of the second one-way bearing locking the longitudinal cutting transmission chain and the first one-way bearing idlening to keep the rotary transmission chain stationary, the automatic switching of the transmission path between the circumferential cutting action and the longitudinal cutting action by a single motor is achieved simply by changing the rotation direction, without the need for an additional switching mechanism or independent motor. The equipment thus enters the longitudinal cutting state. This longitudinal cutting state indicates that the reverse rotational power of the motor has been precisely distributed to the longitudinal cutting transmission chain, while the rotary transmission chain is in a completely stationary and isolated state. The longitudinal cutting blade can perform longitudinal cutting action under the reverse drive of the motor, and the double-blade assembly will not generate any rotation.

[0050] Finally, in the longitudinal cutting state, the longitudinal cutting blade is controlled to move from the first blade position of the double-blade assembly to the second blade position of the double-blade assembly, and then the moving distance of the longitudinal cutting blade is controlled to be the same as the stripping length to complete the longitudinal cutting, thus obtaining the longitudinal cutting result. Specifically, after entering the longitudinal cutting state, the reverse rotational power of the motor is continuously transmitted to the drive mechanism of the longitudinal cutting blade through the longitudinal cutting transmission chain locked by the second one-way bearing. In the handheld stripping device, the longitudinal cutting transmission chain converts the rotational motion of the motor into the linear movement of the longitudinal cutting blade along the axial direction of the wire through the longitudinal cutting screw; in the benchtop stripping device, the longitudinal cutting transmission chain pushes the longitudinal cutting blade to move along the axial direction of the wire through the adjustable connecting rod. In step S101, the longitudinal cutting blade has been pre-placed at the initial position corresponding to the position of the first blade, so in the longitudinal cutting state, the longitudinal cutting blade starts from the position of the first blade and moves along the axial direction of the wire towards the position of the second blade. During its movement, the longitudinal cutter makes longitudinal cuts along the outer surface of the wire's sheath. A longitudinal slit extending along the wire's axial direction is cut between the annular cuts formed by the first and second cuts, connecting the two annular cuts. The moving distance of the longitudinal cutter is precisely controlled to be the same as the preset stripping length; that is, the axial displacement of the longitudinal cutter from the first cut position to the second cut position is equal to the distance between the first and second cuts. For example, when the preset stripping length is 10mm, the longitudinal cutter moves 10mm along the wire's axial direction from the first cut position to the second cut position, thus completing the longitudinal cutting operation. Through the cooperation of this longitudinal slit and the two annular cuts, the outer sheath of the stripped area is completely cut open both circumferentially and axially, forming a peelable state. After the longitudinal cutter reaches the second cut position, the motor stops reversing, indicating that the longitudinal cutting is complete. This result signifies that the outer sheath of the stripped area has been completely severed and separated under the combined action of the annular and longitudinal cuts, providing conditions for the subsequent reset of the equipment and the removal of the stripped outer sheath in step S106.

[0051] In step S106, based on the completion result of longitudinal cutting, the control motor stops running and the switching mechanism is reset to the pressing position to wait for the next stripping operation, thus obtaining a reset standby state.

[0052] In one embodiment, step S106 includes: Based on the longitudinal cutting completion result, the motor is controlled to stop running, and the motor is obtained as a stopped state; The shift fork of the switching mechanism is reset to the pressing position to obtain the mechanism reset state; Release the electromagnet and brake to return all components to their initial positions, achieving a spring-loaded reset state; The dual-blade assembly and the longitudinal cutting blade are returned to their initial positions to obtain the standby position state; The motor stop state, the mechanism reset state, the elastic reset state, and the standby position state are combined and awaited for the next stripping operation to obtain the reset standby state.

[0053] In this embodiment, the motor is stopped based on the completion result of the longitudinal cutting, resulting in a motor-stopped state. In step S105, after the longitudinal cutting blade moves from the first blade position to the second blade position and completes the longitudinal cutting, the outer skin of the peeling area has been completely cut off and separated by the combined action of the circumferential and longitudinal cutting, and the motor no longer needs to provide rotational power. At this time, the motor controller issues a stop command to the motor based on the completion result of the longitudinal cutting, and the motor switches from the reverse running state to the stop state, no longer outputting any rotational power. After the motor stops, both the rotational transmission chain and the longitudinal cutting transmission chain in the transmission mechanism are in a stationary state, and each transmission component no longer generates any movement, thus obtaining the motor-stopped state. This motor-stopped state indicates that all the power drive processes required in the entire peeling operation have ended, providing a static basis for the subsequent reset of each mechanism component.

[0054] Furthermore, the fork of the control switching mechanism is reset to the pressing position, resulting in the mechanism reset state. In step S103, the fork slides from the pressing position to the rotating position under the switching driving force of the electromagnet, switching the transmission path from the pressing channel to the rotating channel to perform subsequent circumferential and longitudinal cutting operations. When the motor stops running, the switching mechanism needs to reset the fork from its current rotating position back to the pressing position so that the transmission path returns to the pressing channel. For handheld stripping equipment, after the operator releases the trigger, the fork automatically slides back from the rotating position to the pressing position under the elastic restoring force of the return spring, re-establishing connection with the pressing linkage. For benchtop stripping equipment, the grooved wheel continues to rotate after the brake is released, automatically rotating to the pressing position of the next work cycle. The above reset operation results in the mechanism reset state, which indicates that the fork of the switching mechanism has returned to the pressing position, the transmission path has returned to the pressing channel, and the equipment can directly drive the double-blade assembly downward through the pressing action in the next operation.

[0055] Furthermore, the electromagnet and brake are released, allowing each component to return to its initial position, achieving a resilient reset state. Specifically, in step S103, the electromagnet is energized to generate an attractive force to drive the shift fork to switch positions. Simultaneously, in the benchtop equipment, the grooved wheel brake is energized to grip the grooved wheel drive shaft, pausing rotation. After the stripping operation is completed and the motor stops running, the control circuit cuts off the power supply to the electromagnet and brake. The electromagnet loses its attractive force after being de-energized, and the brake releases its braking force after being de-energized. After both the electromagnet and brake are de-energized and released, each moving component in the equipment automatically returns to its initial position under the elastic restoring force of its respective reset spring. Each reset spring acts on the shift fork, driven component, and other transmission connection components, causing these components to spring back from their working position during the stripping operation to their initial set position along the direction of the spring force. The automatic reset process driven by the elastic restoring force of the spring results in the elastic reset state. This elastic reset state indicates that all moving parts in the equipment that were in the working position due to the energization of the electromagnet and brake have returned to their initial positions, and the relative positional relationship between the parts has been restored to the state before the stripping operation.

[0056] Furthermore, the dual-blade assembly and the longitudinal cutting blade are returned to their initial positions to obtain a standby position. Specifically, during the elastic reset process, the first and second blades of the dual-blade assembly, under the action of the reset spring, return from the pressed position where they cut into the outer sheath to their initial upper position. That is, the blades of both the first and second blades disengage from the target wire and return to a raised position away from the wire, allowing the wire that has completed the stripping operation to be removed from the blades. At the same time, under the action of the reset spring, the longitudinal cutting blade returns from the position of the second blade along the axial direction of the wire to its initial position corresponding to the position of the first blade. That is, the longitudinal cutting blade returns to the starting position set in step S101, reserving the correct starting point for the next longitudinal cutting operation. After the dual-blade assembly returns to its initial upper position and the longitudinal cutting blade returns to its initial position, the standby position is obtained. This standby position indicates that the two main actuators of the stripping operation have returned to their respective initial positions, and the equipment is structurally ready to receive the next wire to be stripped.

[0057] Finally, the motor stop state, mechanism reset state, elastic reset state, and standby position state are combined and await the next stripping operation to obtain the reset standby state. Once all four states have been achieved—that is, the motor has stopped running, the switching mechanism's fork has reset to the lowering position, the electromagnet and brake have been released and all moving parts have returned to their initial positions under spring action, and the double-blade assembly and longitudinal cutter have returned to their respective initial positions—these four states are combined and confirmed, indicating that all functional components of the equipment have completed a full reset from the working state to the initial state. At this time, the entire equipment enters the reset standby state, that is, the equipment is in the same ready state as after step S101. The operator can then insert the next target wire and repeat the stripping operation process from S101 to S106, thereby realizing the cyclical operation of the stripping work.

[0058] In one specific embodiment, the wire stripping control method based on conductive feedback of this application is described using a handheld stripping device as an example. The handheld stripping device includes a double-blade assembly, a longitudinal slicing blade, a 12V DC motor, an electromagnet-driven switching mechanism fork, and a thyristor control circuit. The control flow is as follows: First, the operator adjusts the handwheel to set the distance between the first and second blades in the double-blade assembly to 10mm, according to the required stripping length (e.g., 10mm). The target wire (e.g., a 3.3 square millimeter PVC insulated wire with a 2mm thick outer sheath) is then placed into the blades.

[0059] The operator pulls the trigger, pushing the double-blade assembly downwards via the pressure lever. As the double-blade assembly cuts into the outer sheath, the control circuit continuously monitors the resistance between the double-blade assembly and the core wire via a conductive spring.

[0060] When the cutting depth reaches 2mm and the blade of the dual-blade assembly contacts the core wire, the sensing resistance changes from open circuit to approximately 5kΩ (depending on the contact area and pressure). The comparator LM358 detects the voltage surge and outputs a high level to trigger the thyristor MCR100-8 to conduct.

[0061] After the thyristor is turned on, the electromagnet is energized, generating a 5N pulling force that pulls the fork of the switching mechanism to switch from the pressing position to the rotating position within 20ms. At the same time, the motor controller receives a trigger signal and first controls the motor to briefly reverse 20 degrees, causing the double-blade assembly to retract 0.2mm via the cam profile.

[0062] The motor then rotates 360 degrees clockwise, locking the rotational drive chain via the first one-way bearing (HF0612), driving the double-blade assembly to rotate one revolution around the target wire, completing the circumferential cut. At this time, the second one-way bearing idles, and the longitudinal cutting drive chain remains stationary.

[0063] After the circumferential cutting is completed, the motor automatically reverses, locking the longitudinal cutting drive chain through the second one-way bearing, driving the longitudinal cutting screw to rotate, and moving the longitudinal cutting blade 10mm from the first blade position to the second blade position to complete the longitudinal cutting. At this time, the first one-way bearing rotates freely, and the double-blade assembly does not rotate.

[0064] Finally, the operator releases the trigger, and all components reset under the action of the springs. The fork returns to the pressing position, ready for the next stripping operation. The entire process takes only 2 to 3 seconds. The cutting depth is automatically controlled by conductive feedback, which can adapt to target wires with different outer sheath thicknesses without damaging the core wire.

[0065] In another specific embodiment, the wire stripping control method based on conductive feedback of this application is described using a benchtop multi-station stripping machine as an example. The benchtop stripping machine includes a grooved wheel indexing mechanism, a four-station turntable, a cylindrical cam group, and a 57-stepper motor. The control flow is as follows: Before starting the equipment, set the peeling length to 15mm and adjust the length of the adjustable connecting rod at the longitudinal cutting station.

[0066] The motor runs continuously at 15 rpm, driving the active dial through the reducer. Every time the dial rotates once (4 seconds), the grooved wheel rotates 90 degrees, sequentially driving the pressing station, rotating station, longitudinal cutting station, and peeling station into their working positions.

[0067] During the pressing position (0 to 1 second), the cylindrical cam drives the double-blade assembly to press down during the 0 to 90 degree push stroke. During the 90 to 100 degree pause (corresponding to 0.9 to 1.0 seconds), the cam profile is a circular arc of equal radius, and the follower is stationary. At this time, continuity testing is performed.

[0068] If the double-blade assembly contacts the core wire, the detection circuit is triggered, the Geneva wheel brake (mounted on the Geneva wheel shaft) is energized and locks, and the cam stops rotating. Simultaneously, an independent electromagnet pulls the driven component, forcing the double-blade assembly to retract by 0.2mm. After a delay of 0.1 seconds, the Geneva wheel brake releases, and the cam continues to rotate to its 180-degree reset.

[0069] At the rotary station (1 to 2 seconds), the cam drives the double-blade assembly to rotate 360 ​​degrees around the target wire via a rack and pinion mechanism to complete the circumferential cutting.

[0070] At the longitudinal cutting station (2 to 3 seconds), the cam pushes the longitudinal cutter 15mm through the adjustable linkage to complete the longitudinal cutting.

[0071] At the peeling station (3 to 4 seconds), the clamps close to hold the outer skin segment, the cam drives the clamps to retract and pull out the waste material, and then release it.

[0072] The entire cycle completes one stripping operation in 4 seconds. The equipment only requires one stepper motor, along with a simple cam and detection circuit to achieve full automation.

[0073] In summary, this application integrates conductivity detection, mechanical transmission, and motor control. For conductivity detection, it utilizes the conductivity of the double-blade assembly itself and the conductivity of the target wire core to form a detection circuit. When the double-blade assembly cuts into the outer sheath and contacts the core, the conductivity detection result is obtained through resistance change, thus adaptively determining the actual thickness of the outer sheath. This eliminates the need for additional independent detection devices such as position sensors, vision systems, or capacitive sensors, reducing the hardware complexity and manufacturing cost of the equipment. Regarding action switching, this application uses a thyristor to receive the conduction signal and achieve rapid triggering. The thyristor's response speed reaches the microsecond level, instantly driving the electromagnet to generate switching force the moment the double-blade assembly contacts the core. This allows the switching mechanism's fork to complete the switch from the pressing position to the rotating position in a very short time, avoiding the risk of damage to the core due to continued pressing of the double-blade assembly caused by response delay, and ensuring timely action switching. In terms of the drive system, this application utilizes the unidirectional transmission characteristics of the first and second one-way bearings to drive the rotary transmission chain and the longitudinal cutting transmission chain respectively through the forward and reverse rotation of a single motor, thereby realizing time-sharing drive of the circumferential cutting action and the longitudinal cutting action. It eliminates the need to configure an independent motor and complex electronic commutation control logic for each action, greatly simplifying the drive system structure and control system architecture of the equipment.

[0074] Finally, this application achieves automatic sequential control of the entire stripping process by combining three technical features: conductivity detection, rapid thyristor triggering, and automatic commutation of one-way bearings. This is done without relying on complex detection systems and multi-motor drive architectures, effectively solving the technical problems of complex overall structure and cumbersome control logic in existing automatic stripping equipment. It has the advantages of low cost and high reliability.
