Abstract
Description
Technical Field
[0001] This application relates to the field of cable stripping equipment technology, and in particular to an electric cable stripping and polishing device. Background Technology
[0002] The basic structure of a cable consists of a conductor, an insulation layer, a shielding layer, and a protective layer. The conductor transmits electrical energy, the insulation layer isolates the cable core from the outside environment, and the protective layer acts as a seal to maintain insulation performance. Cables require stripping in the following situations during actual use: 1. When connecting equipment and electrical boxes, the cable stripping is necessary for connection; 2. At cable joints, the cable stripping is necessary to connect the cable to the conductor, insulation layer, and shielding layer; 3. In some cases, cable protection is required to prevent damage, which also necessitates stripping.
[0003] Currently, cable stripping methods include: manual stripping, which involves manually peeling the insulation off the wires and cables; suitable for simple cables, but inefficient and costly; mechanical stripping, using cable stripping machines, a semi-mechanized operation suitable for large-diameter cables; mechanical crushing, which involves crushing waste wires and cables to remove the insulation, followed by water washing, airflow separation, or electrostatic separation to separate the copper and plastic; freezing, where the copper wire is frozen in a refrigerator and then repeatedly beaten with a mallet or on the ground for easy stripping; flame ablation, which uses flames to burn off the copper insulation, but produces pollution and darkens the surface of the copper wire, affecting its market value; and chemical stripping, which uses organic solvents to dissolve the insulation layer, suitable for large-scale operations, but the solvents are expensive and difficult to process. Therefore, considering both cost and efficiency, mechanical stripping is the preferred method in actual cable stripping processes.
[0004] There are many types of existing cable stripping equipment, but they usually only have the function of stripping, and there is a risk of stripping the cable core. Based on this, researchers have improved stripping equipment, resulting in automated equipment that integrates stripping and grinding. For example, patent application CN116365427A discloses an integrated stripping and grinding equipment for high-voltage cable joints, including a rotating mechanism comprising a rotatable tube with a limit ring rotatably connected to it; and a stripping mechanism fixedly installed on one side of the rotating mechanism, comprising a first turntable with a limit seat fixedly connected to one side, and a screw threaded onto the limit seat. This equipment has the advantage of strong applicability, solving the problem that existing automated systems for stripping and grinding high-voltage cable joints, when processing cables of different diameters, rely on automatically driven rotating, stripping, and grinding mechanisms. This makes it difficult to adjust the stripping and grinding dimensions in real time, easily leading to errors during the stripping and grinding process, resulting in excessive stripping and grinding, which affects the subsequent wiring of the cable joint. However, the cutting blade of the stripping mechanism still poses a risk of stripping the battery cell during rotation, and after stripping, the stripping mechanism needs to be adjusted back to its original state before the grinding mechanism is moved to the position where grinding is required, which is inefficient. Utility Model Content
[0005] In view of the shortcomings of the prior art, the present invention provides an electric cable stripping and polishing device, which can perform stripping and polishing simultaneously without cutting the battery core, thus efficiently completing the stripping and polishing of the cable.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An electric cable stripping and polishing device includes a drive mechanism, a stripping mechanism, and a polishing mechanism. It also includes a fixed disk and a first tray and a second tray rotatably mounted on opposite sides of the fixed disk. The drive mechanism and the stripping mechanism are mounted on the first tray, and the polishing mechanism is mounted on the second tray. The drive mechanism drives the first and second trays to rotate synchronously, and also drives the stripping mechanism and the polishing mechanism to rotate synchronously. The stripping mechanism clamps the cable and controls its travel distance, while simultaneously positioning the stripping mechanism relative to the cable core for rotating and stripping the cable. The polishing mechanism polishes the outer surface of the stripped cable as it travels into the polishing area.
[0008] According to the above-mentioned technical means, this utility model drives the stripping mechanism and the polishing mechanism to rotate synchronously through the first tray and the second tray. The stripped cable is controlled by the travel path of the stripping mechanism and partially enters the polishing area. The polishing mechanism polishes the oxide layer on its outer surface. During this process, the stripping mechanism and the polishing mechanism operate simultaneously, which can efficiently complete the stripping and polishing of the cable. In addition, the stripping mechanism of this utility model can position the relative position of the cable and the battery core to avoid the stripping mechanism cutting the battery core of the cable, resulting in a high degree of cable stripping integrity.
[0009] Furthermore, the wire stripping mechanism includes two clamping blocks mounted on the first tray facing the direction of cable travel, and the clamping surfaces of the clamping blocks have a threaded structure.
[0010] Based on the above technical means, the clamping block with threaded structure of this utility model can achieve precise control of the travel distance of the clamped cable through its thread characteristics. The travel distance can be precisely adjusted by controlling the number of rotations of the thread. Moreover, the inclined surface friction characteristics of the thread pair have a self-locking function, which can automatically maintain the current position after the rotation stops, preventing cable displacement deviation caused by external vibration or load changes.
[0011] Furthermore, the wire stripping mechanism also includes a first positive and negative lead screw, two clamping blocks are movably mounted on the first positive and negative lead screw, the first positive and negative lead screw is rotatably mounted in the wire stripping mechanism, and the distance between the two clamping blocks can be adjusted by its rotational movement.
[0012] Furthermore, the wire stripping mechanism also includes a cutter assembly mounted on the cable travel path and connected to the clamping block. The cutter assembly includes a rotating base and a cutter mounted on the rotating base. The rotating base changes the offset direction of the cutter through its rotational movement.
[0013] Furthermore, the wire stripping mechanism also includes a positioning element mounted on a rotating base for positioning the relative position of the wire stripping mechanism and the cable core. The positioning element is an infrared sensor and / or an electrical sensor.
[0014] Furthermore, it also includes a chip collection box connected to the wire stripping mechanism for collecting cable sheathing.
[0015] Furthermore, a pressure plate is installed in the chip collection box.
[0016] Furthermore, the grinding mechanism includes a mounting base, a second positive and negative lead screw, and two grinding blocks. The two grinding blocks are movably and spaced apart on the second positive and negative lead screw and are mounted in the mounting base via the second positive and negative lead screw. The second positive and negative lead screw can rotate in the mounting base to adjust the distance between the two grinding blocks.
[0017] Furthermore, the grinding block is equipped with an array of grinding brush heads in an arc shape.
[0018] Furthermore, it also includes a power supply assembly mounted on the first tray to provide power to the drive mechanism.
[0019] The beneficial technical effects of this utility model are as follows:
[0020] This utility model features a compact structure, enabling automated, integrated wire stripping and polishing processes with high efficiency. The device utilizes the synchronized rotation of the stripping and polishing mechanisms to strip the cable's insulation. The stripped cable, controlled by the stripping mechanism's travel path, partially enters the polishing area, where the polishing mechanism removes the oxide layer from its outer surface. During this process, the stripping and polishing mechanisms operate simultaneously, efficiently completing both stripping and polishing. Furthermore, the stripping mechanism can precisely position the cable and its core to prevent accidental cutting of the core, thus minimizing damage. Attached Figure Description

Detailed Implementation
[0028] Unless otherwise defined, all technical and / or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should be understood that certain features of this invention (described in the context of separate embodiments for clarity) may also be provided in combination in a single embodiment. Conversely, multiple features of this invention (described in the context of a single embodiment for brevity) may also be provided separately or in any suitable combination or, where appropriate, in any other described embodiment of this invention. Certain features described in the context of various embodiments will not be considered essential features of those embodiments unless the embodiment is inoperable without those elements. The present invention is further illustrated below by specific examples; however, it should be noted that the specific process conditions and results described in the embodiments of this invention are for illustrative purposes only and should not be construed as limiting the scope of protection of this invention. All equivalent changes or modifications made in accordance with the spirit and essence of this invention should be covered within the scope of protection of this invention.
[0029] This utility model provides an electric cable stripping and polishing device, including a drive mechanism, a stripping mechanism, and a polishing mechanism. It also includes a fixed disk 1 and a first tray 2 and a second tray 3, which are rotatably mounted on opposite sides of the fixed disk 1. The drive mechanism and the stripping mechanism are mounted on the first tray 2, and the polishing mechanism is mounted on the second tray 3. The drive mechanism is used to drive the first tray 2 and the second tray 3 to rotate synchronously, and to drive the stripping mechanism and the polishing mechanism to rotate synchronously. The stripping mechanism is used to clamp the cable and control its travel distance, and at the same time, it is used to position the relative position of the stripping mechanism and the cable core to perform rotational stripping of the cable. The polishing mechanism is used to polish the outer surface of the stripped cable that has traveled to the polishing area.
[0030] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the fixed disk 1 of this application can specifically be an open gear disk, which is equipped with multiple bearings, multiple tandem gear sets, and multiple screws. The first tray 2 and the second tray 3 are rotatably mounted on opposite sides of the fixed disk 1 by screws. Furthermore, when the drive mechanism is running, the drive mechanism connects to the gear disk through its main shaft, inputting power to the gear disk. The gear disk transmits rotational motion to the adjacent driven gear set through the meshing of its tooth profiles, forming a mechanical energy transmission path, thereby creating continuous rotation of multiple tandem gear sets in the gear disk, which in turn drives the first tray 2 and the second tray 3 to rotate synchronously. During this process, the gear disk of this application remains fixed, and its transmission smoothness is high.
[0031] Furthermore, a mounting post 4 is fixedly connected below the mounting plate 1 in this application. The fixing method includes, but is not limited to, welding, screw connection, and hinge. An insulating rod is independently installed in the usage site of the equipment. This application connects the insulating rod to the mounting post 4, combining the equipment with the insulating rod to ensure that the overall equipment meets insulation requirements and complies with power industry safety regulations. This avoids short circuits that may occur during live wire stripping due to contact with conductors at different potentials caused by the metal stripping mechanism. This application uses the insulating rod connected to the mounting post 4 to block the current conduction path, reducing the risk of discharge and arc burns.
[0032] Furthermore, this application utilizes a stripping mechanism to remove the protective and insulation layers from the outer surface of the cable, exposing the internal battery core and facilitating operations such as wire connection, welding, or terminal crimping. Specifically, the stripping mechanism of this application has a positioning function, enabling precise stripping to avoid damage to the internal battery core, such as broken strands or scratches, thus ensuring the conductivity and mechanical strength of the cable core. This application utilizes a grinding mechanism to remove the oxide layer or residual insulation debris from the battery core surface, making the outer surface of the battery core smoother, reducing contact resistance at connection points, and preventing localized overheating. The cleaner surface of the cable core after grinding can improve the strength of solder joints or the adhesion of crimped terminals, ensuring stable current transmission. In this application, stripping and grinding form a continuous process chain; the former addresses the need for battery core exposure, while the latter optimizes the surface condition of the battery core. Together, they ensure the reliability, safety, and long-term stability of the cable core connection.
[0033] Furthermore, the wire stripping mechanism includes two clamping blocks 22 mounted on the first tray 2 facing the cable travel direction, and the clamping surfaces of the clamping blocks 22 have a threaded structure. The clamping blocks 22 with threaded structures (not shown in the figures) of this application can achieve precise control of the travel distance of the clamped cable through their thread characteristics. Precise adjustment of the travel distance can be achieved by controlling the number of rotations of the thread, and the inclined surface friction characteristics of the threaded pair have a self-locking function, automatically maintaining the current position after rotation stops, preventing cable displacement deviation caused by external vibration or load changes. Specifically, when the cable enters the clamping area of the clamping block 22, the cable is clamped by the two clamping blocks 22. When the clamping block 22 rotates, the threaded structure of its clamping surface converts its rotational torque into a linear thrust along the axial direction of the cable, achieving an efficient conversion between the rotational motion of the clamping block 22 and the linear motion of the cable. For each rotation of the clamping block 22, the cable moves a distance along its axis equal to the pitch of the threaded structure. For example, the pitch of the threaded structure in this application is 0.5 mm, and the clamping block 22 rotates twice, pushing the cable to a linear displacement of 1 mm in its direction of travel. Furthermore, the clamping surface of the clamping block 22 in this application is a concave arc shape with a threaded structure. The curvature of the concave arc shape can be adapted to cables of different diameters. The material of the clamping block 22 includes, but is not limited to, hard alloys such as high-strength alloy steel, polyurethane rubber, and aluminum alloy composite materials. The size and specifications of the clamping block 22 are set according to actual usage requirements and cable travel distance requirements. Specifically, the clamping block 22 of this application is equipped with a clamping bracket 21, multiple support brackets 24, multiple mounting plates and multiple screws, so as to fix the two clamping blocks 22 to the first tray 2 through the above components.
[0034] Furthermore, such as Figure 3As shown, the wire stripping mechanism also includes a first positive and negative lead screw 23. Two clamping blocks 22 are movably mounted on the first positive and negative lead screw 23. The first positive and negative lead screw 23 is rotatably mounted in the wire stripping mechanism, and its rotational movement can adjust the distance between the two clamping blocks 22. The drive mechanism of this application includes a first motor 5, a second motor 6, and a third motor 7. The first motor 5 is the power motor for the rotation of the entire device, and it can be a two-phase motor, a three-phase motor, or a stepper motor, etc. The first motor 5 is mounted on the first tray 2, providing power for the rotation of the first tray 2 and the second tray 3. The second motor 6 is mounted on the clamping blocks 22, used to provide power for the first positive and negative lead screw 23. The first positive and negative lead screw 23 has left-hand threads and right-hand threads machined on the same shaft. When the first positive and negative lead screw 23 is driven by the second motor 6, it uses the difference in thread direction to achieve synchronous reverse movement of the two movable clamping blocks 22, thereby precisely adjusting the distance between them so that the distance matches the diameter of the cable, thus completing the clamping of the cable. Furthermore, when the first motor 5 of this application is running, it can simultaneously realize three movements, including driving the clamping block 22 and the first tray 2 to rotate, and pushing the cable to move linearly in its direction of travel based on the rotation of the clamping block 22, and driving the second tray 2 to drive the grinding mechanism to rotate to grind the stripped cable.
[0035] Furthermore, such as Figure 1 and Figure 3 As shown, the wire stripping mechanism also includes a cutter 26 assembly mounted on the cable travel path and connected to the clamping block 22. The cutter 26 assembly includes a rotating base 25 and a cutter 26 mounted on the rotating base 25. The rotating base 25 changes the offset direction of the cutter 26 through its rotational movement. The cutter 26 assembly also includes multiple mounting plates and support frames 24, a blade adjusting screw 28, and a blade adjusting brushed motor 29. Furthermore, the rotating base 25, the blade adjusting screw 28, and the blade adjusting brushed motor 29 are assembled and connected to the clamping block 22 by multiple mounting plates and screws. The blade of the cutter 26 in this application has an arc-shaped structure. This arc-shaped blade contacts the cable surface through a continuous curve, so that the cutting force is evenly distributed along the tangential direction. Compared with the traditional straight blade edge, it reduces most of the local stress concentration, which can reduce the wear of the cutter 26. In addition, the top of the cutter 26 in this application has an arc-shaped chip breaking groove structure, which can accelerate the curling and deformation of the chips and effectively prevent the chips from entangled and affecting the normal operation of the equipment. In addition, the cutter 26 of this application can produce a progressive cutting effect when performing high-speed wire stripping. With the drive of the brushed motor 29, it can achieve high-frequency wire stripping stability and high wire stripping integrity.
[0036] Furthermore, the adjusting screw 28 of this application, driven by the adjusting brush motor 29, can achieve high-precision displacement to compensate in real time for the position deviation of the cutter 26 caused by the diameter fluctuation of the cable stripping. The helical transmission of the adjusting screw 28 converts the rotation of the adjusting brush motor 29 into the linear displacement of the cutter 26, ensuring a small stripping depth error. In addition, the rotating base 25 of this application, driven by the adjusting brush motor 29, dynamically adjusts the contact angle between the cutter 26 and the cable, realizing a multi-angle variable cutting tilt angle, such as 15° to 65°.
[0037] Furthermore, such as Figure 1 As shown, the stripping mechanism also includes a positioning element 27 mounted on the rotating base 25 for positioning the relative position of the stripping mechanism and the cable core. The positioning element 27 is an infrared sensor and / or an electrical sensor. The positioning element 27 can be fixed in the rotating base 25 by welding, hinge, screw connection, or bonding. The infrared sensor in this application is an active infrared sensor, which includes a transmitting module and a receiving module. When the positioning element 27 is an infrared sensor, it emits 940nm wavelength infrared light to detect changes in the reflected signal when the blade of the cutter 26 contacts the cable core, and measures the distance between the cutter 26 and the cable core in real time, thus providing precise over-cutting protection for cable stripping. When the positioning element 27 is an electric sensor, the blade of the cutter 26 contacts the battery cell. The conductivity of the battery cell causes a sudden change in the surrounding electromagnetic field. The sensing probe of the electric sensor captures the change in magnetic field strength in real time and generates a microvolt-level voltage signal through coil induction. Through the synergistic effect of sensing the sudden change in electromagnetic field and analyzing the pulse current characteristics, the electric sensor achieves a millisecond-level response at the moment the blade contacts the battery cell, providing a reliable safety guarantee for the live wire stripping operation.
[0038] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, it also includes a chip collection box 9 connected to the wire stripping mechanism for collecting cable sheathing. The chip collection box 9 is assembled with the cutter 26 assembly to collect all the cable sheathing cut by the cutter 26, reducing the risk of sheathing scattering and preventing it from entering the air or polluting the factory environment. This application does not limit the shape and size of the chip collection box 9; it can be configured according to actual needs, such as a rectangular chip collection box 9.
[0039] Furthermore, the chip collection box 9 of this application is equipped with a pressure plate (not shown in the figure). The pressure plate of this application can compress the loose cable sheath entering the chip collection box 9 into block-shaped objects through mechanical pressure, thereby reducing its volume. Moreover, the surface structure of the pressure plate can be designed, such as setting staggered groove textures on the surface, to suppress the rebound expansion of the compressed cable sheath and the random flying of cable sheath, which would affect the normal operation of the equipment.
[0040] Furthermore, such as Figure 2 and Figure 4 As shown, the grinding mechanism includes a mounting base 31, a second forward and reverse lead screw 32, and two grinding blocks 33. The two grinding blocks 33 are movably and spaced apart on the second forward and reverse lead screw 32 and are mounted in the mounting base 31 via the second forward and reverse lead screw 32. The second forward and reverse lead screw 32 can rotate within the mounting base 31 to adjust the distance between the two grinding blocks 33. The mounting base 31 includes multiple mounting base plates, multiple screws, a series gear set, multiple bearings, and multiple mounting covers. The multiple mounting base plates, multiple bearings, and multiple mounting covers are assembled together with multiple screws according to the design drawings to form the mounting base 31, and a mounting position for the third motor 7 is reserved. The third motor 7 is mounted in the mounting base 31, and its bearings are connected to the series gear set. When the third motor 7 is running, it drives the series gear set to rotate, thereby driving the second forward and reverse lead screw 32, which is movably connected to the series gear set, to rotate. The second forward and reverse lead screw 32 of this application has left-hand thread and right-hand thread machined on the same shaft. When the second forward and reverse lead screw 32 is driven by the third motor 7, it uses the difference in thread direction to realize the synchronous reverse movement of the two movable grinding blocks 33, thereby precisely adjusting the distance between them so that the distance matches the diameter of the cable core, thereby completing the grinding of the outer surface of the cable core.
[0041] Furthermore, the polishing block 33 is provided with an arc-shaped polishing brush head array 331. The polishing brush head array 331 of this application includes several polishing brush heads. The material of the polishing brush heads is selected according to the performance of the oxide layer on the outer surface of different battery cells. For example, the material of the polishing brush heads can be high-density nylon bristles, which have excellent wear resistance, can withstand repeated friction on the surface of the metal battery cell, and have a Shore hardness of 70A to 85A, which can remove the oxide layer while avoiding damage to the surface finish of the battery cell; the material can be a silicone rubber matrix, which has antistatic properties and can prevent the risk of leakage during polishing. Furthermore, the polishing brush heads of this application all have a certain tilt angle, which is set according to actual needs, for example, 10° to 30°. This application utilizes the tilted polishing brush heads to form tangential contact with the surface of the battery cell, increasing the frictional force per unit area, effectively removing the oxide layer and metal burrs on the outer surface of the battery cell, and compensating for the torsional stress of the cable battery cell by the angle, avoiding missed polishing of some areas due to the rotation of the battery cell during polishing. Furthermore, the inclined polishing brush head of this application can simultaneously cover any part of the battery cell, thereby reducing the difference in polishing depth between different parts of the battery cell. The arc-shaped arrangement of the polishing brush head array 331 of this application can form a continuous gradient pressure band on the contact surface, reducing the risk of stress concentration, and automatically adapting to the curvature of the cylindrical cable battery cell surface, avoiding battery cell fatigue damage caused by local overload; in addition, the arc-shaped structure of the polishing brush head array 331 of this application generates centripetal force compensation when the polishing mechanism rotates at high speed, ensuring that each polishing brush head maintains a constant contact depth with the outer surface of the battery cell, such as 0.1mm to 0.3mm.
[0042] Furthermore, it also includes a power supply assembly mounted on the first tray 2 to provide power to the drive mechanism. The power supply assembly of this application can be a battery 8, such as 8 sets of lithium manganese iron phosphate batteries, 8 sets of nickel-cadmium batteries, and 8 sets of lithium thionyl chloride batteries, etc., which has the advantages of high power output, good stability, and durability, and is suitable for industrial applications of the equipment.
[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
