Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and more specifically, to a cable sheath stripping device and stripping method. Background Technology

[0002] Cables, as the lifeline of modern power transmission systems, bear the vital mission of transmitting electricity. Especially in high-voltage transmission networks, the functionality and safety of the cable sheath directly affect the stable operation of the entire power grid. The cable sheath not only protects the internal conductors from damage by the external environment but also provides multiple protective functions, including insulation, waterproofing, and fireproofing, ensuring the safe and efficient transmission of electricity. During cable laying and maintenance, precise stripping of the sheath is a necessary step for connecting cables or installing terminal accessories, and its importance cannot be underestimated. Correct stripping protects the cable insulation from damage, ensuring the long-term reliable operation of the power system. Conversely, improper stripping may damage the cable's function, create safety hazards, or even cause power outages, affecting social production and people's lives.

[0003] Currently, cable sheath stripping mainly relies on manual tools or simple mechanical devices, such as stripping pliers and stripping knives, as well as some more advanced electric or pneumatic stripping equipment. However, these devices generally have the problem of not being able to automatically identify the different material layers in the cable sheath and accurately adjust the cutting pressure. Cable sheaths are usually composed of multiple layers of different materials. During the stripping process, if the cutting pressure is not adjusted in a timely manner according to the material characteristics of different layers, the sheath may be torn due to excessive cutting pressure, or the cutting depth may be insufficient due to insufficient cutting pressure, thus seriously reducing the cutting quality and efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a cable sheath stripping device and method that can solve the problem that existing cable sheath stripping devices cannot independently identify different material layers in the cable sheath and accurately adjust the cutting pressure, resulting in poor cutting quality and low cutting efficiency.

The cutting component further includes a connecting part. One end of the connecting part is threadedly connected to the transmission screw rod, and the other end is connected to the cutting tool head. The driving part can drive the cutting tool head to approach or move away from the layer to be cut through the connecting part.

[0008] Further, the cable sheath stripping device further includes a third mounting seat. The third mounting seat is arranged on the second mounting seat. The driving part is arranged on the third mounting seat. The pressure adjustment component further includes a synchronous belt and a synchronous pulley. The synchronous pulley is sleeved on the transmission screw rod and is drivingly connected to the transmission screw rod. The synchronous belt is sleeved on the driving shaft of the driving part and the synchronous pulley. An installation part is further arranged on the first mounting seat. One end of the transmission screw rod is rotatably arranged on the installation part, and the other end is threadedly connected to the connecting part.

[0009] Further, a pressure sensor is further arranged between the connecting part and the cutting tool head. The pressure sensor can detect the cutting pressure.

[0010] Further, a buffer part is further arranged between the second mounting seat and the first mounting seat. The buffer part can apply an elastic buffer force to the second mounting seat along the sliding direction of the second mounting seat.

[0011] Further, a chute extending along the sliding direction of the second mounting seat is arranged on the second mounting seat. The cutting component includes a sliding part. The sliding part is slidably arranged in the chute. The connecting part, the pressure sensor and the cutting tool head are arranged on the sliding part.

[0012] According to another aspect of the present invention, a cable sheath stripping method is further provided. The above cable sheath stripping device is adopted. The stripping method includes: identifying the material of the layer to be cut; adjusting the cutting pressure according to the material of the layer to be cut.

[0013] Further, when the identification component includes a laser sensor, the step of the identification component identifying the material of the layer to be cut includes: defining the number of cycles n and inputting the initial number of cycles n = 0; inputting the maximum cycle threshold M; the laser sensor obtaining the metal reflectivity R of the layer to be cut; when R < 1%, outputting the identification result as the hot melt adhesive layer and initializing the number of cycles; returning to the step of the laser sensor obtaining the metal reflectivity R of the layer to be cut; when 1% ≤ R ≤ 10%, outputting the identification result as the outer sheath and initializing the number of cycles; returning to the step of the laser sensor obtaining the metal reflectivity R of the layer to be cut; when 10% < R < 80%, outputting the number of cycles and calculating the number of cycles n = n + 1 and comparing n with M; when n < M, returning to the step of the laser sensor obtaining the metal reflectivity R of the layer to be cut; when n = M, controlling the device to stop and alarm; when 80% ≤ R, outputting the identification result as the aluminum sheath; returning to the step of the laser sensor obtaining the metal reflectivity R of the layer to be cut.

[0014] Furthermore, the step of adjusting the cutting pressure according to the material of the layer to be cut includes: acquiring cutting pressure data from a pressure sensor; inputting the cutting pressure range corresponding to different materials of the layer to be cut; determining the corresponding cutting pressure range based on the material data of the layer to be cut; comparing the cutting pressure data with the cutting pressure range; when the cutting pressure data is higher than the cutting pressure range, controlling the drive unit to move the cutting head away from the layer to be cut; returning to the step of acquiring cutting pressure data from the pressure sensor; when the cutting pressure data is within the cutting pressure range, returning to the step of acquiring cutting pressure data from the pressure sensor; when the cutting pressure data is lower than the cutting pressure range, controlling the drive unit to move the cutting head closer to the layer to be cut; returning to the step of acquiring cutting pressure data from the pressure sensor.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] See also Figures 1 to 2 As shown, the present invention provides a cable sheath stripping device, including a first mounting base 1 and an identification component. The identification component can identify the material of the layer 6 to be cut. The first mounting base 1 is provided with a cutting component and a pressure adjustment component. The pressure adjustment component can adjust the cutting pressure of the cutting component according to the material of the layer 6 to be cut.

[0023] In the above technical solution, the first mounting base 1 serves as the support and fixing foundation for the entire stripping device, providing a reliable platform for the precise coordination of other components. The identification component typically includes identification devices such as laser recognition sensors or visual recognition sensors, which can identify the material of the current layer 6 to be cut based on the different characteristics of different materials during cable stripping, providing a data basis for subsequent stripping pressure adjustment. The pressure adjustment component typically includes components such as a drive device, and its main function is to dynamically adjust the cutting pressure of the cutting head on the cable sheath based on the material information identified by the identification component. Through the joint cooperation of the identification component and the pressure adjustment component, the cable sheath stripping device can autonomously identify the material of the current layer 6 to be cut during cable stripping and precisely adjust the cutting pressure, thereby avoiding defects such as over-cutting or insufficient depth, and significantly improving stripping quality and efficiency.

[0024] In one embodiment of the present invention, the cable sheath stripping device further includes a second mounting base 4, which is slidably disposed on the first mounting base 1. The cutting component is slidably disposed on the second mounting base 4. The cutting component includes a cutting head 22. The pressure adjustment component can drive the cutting head 22 to move closer to or further away from the layer to be cut 6 to adjust the cutting pressure.

[0025] In the above technical solution, the second mounting base 4 is disposed on the first mounting base 1 and can slide relative to the first mounting base 1, mainly for supporting the cutting assembly. The cutting assembly is used to strip the cable sheath, wherein the cutting head 22 is used to actually contact and cut the cable sheath. The pressure adjustment assembly can, according to the material of the layer 6 to be cut identified by the identification assembly, move the cutting assembly closer to the layer 6 to be cut to increase the cutting pressure of the cutting head 22 on the cable sheath, or move the cutting assembly away from the layer 6 to be cut to reduce the cutting pressure of the cutting head 22 on the cable sheath, thereby achieving adjustment of the cutting pressure.

[0026] In one embodiment of the present invention, the cutting head 22 includes a roller and a wedge-shaped blade. The roller conforms to the curvature of the cable, and the wedge-shaped blade completes burr-free cutting with an ultra-thin 0.8mm cutting edge.

[0027] In the above technical solution, the roller's function is to conform to the cable's curvature, adapting to the cable's circular or curved surface, ensuring that the cutting head 22 maintains good contact with the cable throughout the stripping process. This helps maintain the stability of the cutting process and improves cutting accuracy. Furthermore, the roller can adjust the cutting head position in real time according to changes in the cable's surface curvature to adapt to minute variations, avoiding additional stress during stripping and thus reducing burrs and improving cut quality. The wedge-shaped blade is designed with an ultra-thin 0.8mm cutting edge, ensuring that the blade can cut with a small contact area. This reduces friction between the blade and the sheath during cutting, lowers cutting force, prevents tearing of the sheath material, and significantly reduces burrs on the cut edge, improving the smoothness of the cut surface.

[0028] In one embodiment of the present invention, the pressure adjustment assembly includes a drive unit 31 and a transmission screw 32. The drive unit 31 is drivenly connected to the transmission screw 32. The cutting assembly also includes a connecting part 23. One end of the connecting part 23 is threadedly connected to the transmission screw 32, and the other end is connected to the cutting head 22. The drive unit 31 can drive the cutting head 22 to move closer to or away from the layer 6 to be cut through the connecting part 23.

[0029] In the above technical solution, the drive unit 31 typically includes a stepper motor or other drive device, which provides power for the cutting head 22 to move closer to or further away from the layer 6 to be cut. The stepper motor can perform precise rotational movements according to the instructions of the control system, featuring high positioning accuracy and precise speed control, thus enabling accurate regulation of the cutting pressure. The transmission screw 32, through its cooperation with the drive unit 31, converts the rotational motion at the output end of the drive unit 31 into linear motion, achieving high power transmission accuracy. The connecting part 23, through its threaded engagement with the transmission screw 32, transmits the linear motion to the cutting head 22.

[0030] In one embodiment of the present invention, the cable sheath stripping device further includes a third mounting base 5, which is disposed on the second mounting base 4. The drive unit 31 is disposed on the third mounting base 5. The pressure adjustment assembly further includes a synchronous belt 33 and a synchronous pulley 34. The synchronous pulley 34 is sleeved on the transmission screw 32 and is connected to the transmission screw 32 in a driving connection. The synchronous belt 33 is sleeved on the drive shaft of the drive unit 31 and the synchronous pulley 34. The first mounting base 1 is also provided with a mounting part 11. One end of the transmission screw 32 is rotatably disposed on the mounting part 11, and the other end is threadedly connected to the connecting part 23.

[0031] In the above technical solution, the main function of the third mounting base 5 is to provide a mounting position for the drive unit 31. The third mounting base 5 is placed on the second mounting base 4 to ensure that the drive unit 31 can maintain a relatively fixed position relative to the second mounting base 4. The synchronous belt 33 and synchronous pulley 34 are used to transmit the rotational motion output by the drive unit 31 to the transmission screw 32 in a high-precision, low-delay manner. The synchronous belt and synchronous pulley are characterized by a constant transmission ratio, thus enabling precise control of the rotational speed and angle of the transmission screw 32 through the drive unit 31, thereby achieving precise control of the movement of the cutting head 22. The first mounting base 1 is also provided with a mounting part 11, which is mainly used to support the transmission screw 32, ensuring that the transmission screw 32 can achieve smooth and precise transmission.

[0032] In one embodiment of the present invention, the third mounting base 5 includes a first mounting section and a second mounting section. The first mounting section is disposed on the second mounting base 4 and extends vertically. The synchronous wheel 34 is rotatably disposed on the first mounting section. The transmission screw 32 passes through the first mounting section and connects the synchronous wheel 34 and the connecting part 23 located on both sides of the first mounting section. The second mounting section is connected to the first mounting section and extends toward the direction of the layer to be cut. The driving part 31 is disposed on the second mounting section.

[0033] In the above technical solution, the first mounting section is set on the second mounting base 4 and extends vertically, providing a foundation for the installation and support of the synchronous pulley 34 and the transmission screw 32, making the installation of the synchronous pulley 34 and the transmission screw 32 more stable and reducing the vibration of the transmission system during the peeling process. The second mounting section is set on the first mounting section and extends towards the layer 6 to be cut, forming a platform for installing the drive unit 31. This layout facilitates the installation and maintenance of the drive unit 31. At the same time, after installation, the drive unit 31 is located above the connecting part 23 or the pressure sensor 24, making the overall structure of the peeling device more compact and improving space utilization.

[0034] In one embodiment of the present invention, a pressure sensor 24 is further provided between the connecting part 23 and the cutting head 22, and the pressure sensor 24 can detect the cutting pressure.

[0035] In the above technical solution, when the cutting head 22 cuts the cable sheath, it will be subjected to a force from the cable sheath toward the connecting part 23. This force is equal to the cutting pressure applied by the cutting head 22 to the cable sheath. Therefore, the pressure sensor 24 set between the connecting part 23 and the cutting head 22 can monitor the cutting pressure and feed back the collected cutting pressure data to a control system such as a PLC, so as to provide a basis for the subsequent control system to adjust the cutting pressure according to the type of the layer 6 to be cut.

[0036] In one embodiment of the present invention, a buffer portion 35 is further provided between the second mounting base 4 and the first mounting base 1, and the buffer portion 35 can apply an elastic buffering force to the second mounting base 4 along the sliding direction of the second mounting base 4.

[0037] In the above technical solution, the buffer part 35 is usually made of elastic material, such as a spring or elastic pad, and its function is to provide elastic buffering force for the second mounting base 4 in the sliding direction. When stripping the cable sheath, the cable may experience slight radial movement or vibration due to irregularities in its installation position or internal structure. This movement or vibration is transmitted to the second mounting base 4 through the cutting head 22, the connecting part 23, and the transmission screw 32 threadedly connected to the connecting part 23, causing the second mounting base 4 to move in the sliding direction on the first mounting base 1. By providing the buffer part 35 between the second mounting base 4 and the first mounting base 1, these vibrations and impacts can be absorbed, ensuring that the second mounting base 4 and the cutting components mounted on it remain stable during the stripping process. This ensures that the cutting head 22 can stably adhere to the cable surface, avoiding cut deviation or burr formation, and significantly improving the stability of the stripping process and the cut quality.

[0038] In one embodiment of the present invention, the buffer part 35 is an elastic compression spring, preferably an elastic compression spring with a diameter of 3cm, which connects the first mounting base 1 and the connecting part 23 to achieve buffering of the second mounting base 4.

[0039] In one embodiment of the present invention, a groove extending along the sliding direction of the second mounting base 4 is provided on the second mounting base 4, and the cutting assembly includes a sliding part 42, which is slidably disposed in the groove, and a connecting part 23, a pressure sensor 24 and a cutting head 22 are disposed on the sliding part 42.

[0040] In the above technical solution, the chute is located on the second mounting base 4 and extends along the sliding direction of the second mounting base 4, thereby providing guidance and constraint for the linear movement of the cutting assembly. The sliding part 42 is used to support the connecting part 23, the pressure sensor 24 and the cutting head 22. Through the cooperation of the chute and the sliding part 42, the cutting head 22 can slide linearly along a predetermined trajectory when stripping the cable sheath, avoiding lateral displacement of the cutting assembly, thereby improving the stripping accuracy and reliability.

[0041] See also Figures 1 to 2 As shown, the present invention also provides a cable sheath stripping method, which uses the cable sheath stripping device of the above embodiment. The stripping method includes: identifying the material of the layer to be cut; and adjusting the cutting pressure according to the material of the layer to be cut.

[0042] In the above technical solution, the cable sheath is usually composed of multiple material layers. For example, the outer sheath may be made of plastic or other polymer materials. In addition, it also includes metal sheaths such as aluminum or copper, and there may also be a hot-melt adhesive layer in the middle. The hardness, toughness, and thermal sensitivity of different material layers are different. If the cutting pressure is not matched and adjusted to the appropriate value according to the material characteristics of different layers, it is easy to cause problems such as poor cutting quality and low cutting efficiency. Therefore, the material of the layer to be cut is first identified, and then the cutting pressure is adjusted according to the identified material type of the layer to be cut, ensuring that neither the next layer of material will be damaged nor the stripping will be incomplete due to insufficient pressure during the stripping process, improving the quality and efficiency of cable sheath stripping.

[0043] In one embodiment of the present invention, when the identification component includes a laser sensor, the steps for the identification component to identify the material of the layer to be cut include: defining the number of cycles n and inputting the initial number of cycles n = 0; inputting the maximum cycle threshold M; the laser sensor obtains the metal reflectivity R of the layer to be cut; when R < 1%, the output identification result is the hot-melt adhesive layer and the number of cycles is initialized; return to the step of the laser sensor obtaining the metal reflectivity R of the layer to be cut; when 1% ≤ R ≤ 10%, the output identification result is the outer sheath and the number of cycles is initialized; return to the step of the laser sensor obtaining the metal reflectivity R of the layer to be cut; when 10% < R < 80%, the number of cycles is output and the number of cycles n = n + 1 is calculated and n is compared with M; when n < M, return to the step of the laser sensor obtaining the metal reflectivity R of the layer to be cut; when n = M, the control device stops and alarms; when R ≥ 80%, the output identification result is the aluminum sheath; return to the step of the laser sensor obtaining the metal reflectivity R of the layer to be cut.

[0044] In the above technical solution, defining the number of cycles n and inputting the maximum cycle threshold M is used to prevent the laser sensor from falling into an infinite loop when it cannot recognize the material, protecting the stable operation of the laser sensor and the entire device. Since different cable sheath materials have different reflection characteristics, the laser sensor can quantitatively identify different materials by obtaining the reflectivity, providing accurate data support for subsequent pressure adjustment. The reflection characteristic of the hot melt adhesive layer is usually semi-transparent scattering, so the metal reflectivity is extremely low. When R < 1%, the recognition result is output as the hot melt adhesive layer, and at the same time, the number of cycles is initialized to facilitate the recognition component to continue the next round of recognition work. The reflectivity of the outer sheath is usually in a range that is lower but higher than that of the hot melt adhesive layer. Therefore, when 1% ≤ R ≤ 10%, the recognition result is output as the outer sheath. When 10% < R < 80%, the control system cannot correspond the reflectivity in this interval to the sheath material used in the cable sheath, so it cannot recognize the material of the currently to-be-cut layer. This may be caused by the detection error of the laser sensor. Therefore, the step of the laser sensor obtaining the metal reflectivity R of the to-be-cut layer is returned for re-detection, and at the same time, the number of cycles is counted to avoid falling into an infinite loop. If the material of the to-be-cut layer can be normally recognized after re-detection, the next recognition is normally carried out after initializing the cycle technology. If the material of the to-be-cut layer still cannot be normally recognized after repeating many times until n = M, the control device stops and alarms, avoiding misoperations caused by material recognition failures and enhancing the safety and reliability of the system. The aluminum sheath has a high reflectivity. Therefore, when R ≥ 80%, the recognition result is output as the aluminum sheath.

[0045] In one embodiment of the present invention, the step of adjusting the cutting pressure according to the material of the to-be-cut layer includes: the pressure sensor obtains the cutting pressure data; inputs the cutting pressure ranges corresponding to different materials of the to-be-cut layers; determines the corresponding cutting pressure range according to the material data of the to-be-cut layer; compares the cutting pressure data with the cutting pressure range; when the cutting pressure data is higher than the cutting pressure range, controls the driving part to drive the cutting tool head to move away from the to-be-cut layer; returns to the step of the pressure sensor obtaining the cutting pressure data; when the cutting pressure data is within the cutting pressure range, returns to the step of the pressure sensor obtaining the cutting pressure data; when the cutting pressure data is lower than the cutting pressure range, controls the driving part to drive the cutting tool head to move closer to the to-be-cut layer; returns to the step of the pressure sensor obtaining the cutting pressure data.

[0046] In the above technical solution, cutting pressure data is acquired through a pressure sensor to monitor the actual pressure applied by the cutting head to the cable sheath during the stripping process, providing data for subsequent pressure adjustments. By inputting the cutting pressure range corresponding to different layers to be cut, a relationship between material and pressure is established. A suitable stripping pressure range for each material layer is preset, guiding the pressure to adaptively adjust based on the material detected by the laser sensor. Then, based on the material identification results from the laser sensor, the most suitable cutting pressure range is automatically matched, making pressure control more intelligent and precise. Subsequently, the acquired cutting pressure data is compared with the cutting pressure range to check whether the current cutting pressure is within the preset reasonable range, allowing for timely adjustments. When the cutting pressure data is higher than the cutting pressure range, the control drive unit moves the cutting head away from the layer to be cut, thereby reducing the cutting pressure and preventing tearing of the sheath layer or excessive cutting depth. When the cutting pressure data is lower than the cutting pressure range, the control drive unit moves the cutting head closer to the layer to be cut, thereby increasing the cutting pressure and preventing insufficient cutting depth. When the cutting pressure data is within the appropriate cutting pressure range, no adjustment of the cutting pressure is required. After the data range comparison is completed, the system returns to the step of obtaining cutting pressure data from the pressure sensor to continue monitoring the cutting pressure. This achieves a closed-loop control mechanism for monitoring, comparing, and adjusting the cutting pressure, ensuring that the peeling process always operates under optimal cutting pressure conditions. It can control pressure fluctuations within ±5%, thereby significantly enhancing the control system's ability to precisely regulate the peeling process.

[0047] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: The first mounting base 1 serves as the support and fixing foundation for the entire stripping device, providing a reliable platform for the precise coordination of other components. The identification component typically includes identification devices such as laser identification sensors or visual identification sensors, which can identify the material of the current layer 6 to be cut based on the different characteristics of different materials during cable stripping, providing a data basis for subsequent stripping pressure adjustment. The pressure adjustment component typically includes components such as a drive device, whose main function is to dynamically adjust the cutting pressure of the cutting head on the cable sheath based on the material information identified by the identification component. Through the joint cooperation of the identification component and the pressure adjustment component, the cable sheath stripping device can autonomously identify the material of the current layer 6 to be cut during cable stripping and precisely adjust the cutting pressure, thereby avoiding defects such as over-cutting or insufficient depth, and significantly improving stripping quality and efficiency.
