Description

Technical Field

[0001] The present application relates to the technical field of cable stripping equipment, and in particular to an electric cable stripping and polishing device. Background Art

[0002] The basic structure of a cable consists of a conductor, insulation layer, shielding layer, and protective layer. The conductor transmits electrical energy, the insulation layer isolates the core from the outside world, and the protective layer acts as a seal to maintain insulation performance. Cable stripping is necessary in the following situations during actual use: 1. When connecting equipment and electrical boxes, the cable needs to be stripped to facilitate connection; 2. At cable joints, the cable needs to be stripped to connect the cable to the conductor, insulation layer, and shielding layer; 3. In some cases, cable protection is required to protect the cable from damage, which also requires stripping.

[0003] Currently, cable stripping methods include: manual stripping, which involves manually removing the sheath from wires and cables. This method is suitable for simple cables, but is inefficient and costly. Mechanical stripping, which uses a cable stripping machine and is a semi-mechanized process suitable for large-diameter cables. Mechanical pulverization, which removes the sheath from scrap wires and cables by pulverizing them, then separates the copper from the plastic using water washing, airflow differentiation, or electrostatic separation. Freezing, which involves freezing the copper wire in a refrigerator and then repeatedly hitting it with a mallet or the ground, allows for easy stripping. Flame ablation, which uses flames to burn off the copper wire's outer covering, can cause pollution and darken the surface, affecting its market value. Chemical stripping, which uses organic solvents to dissolve the insulation layer, is suitable for large-scale operations, but the solvents are expensive and difficult to process. Therefore, based on a comprehensive consideration of cost and efficiency, mechanical stripping is the preferred method for actual cable stripping.

[0004] There are many types of existing cable stripping equipment, but they usually only have the function of stripping, and there may be a risk of stripping the cable core. Based on this, researchers have improved the stripping equipment and derived an integrated stripping and grinding automated device. For example, the patent application document with publication number CN116365427A discloses a high-voltage cable joint stripping, cutting and grinding integrated device, including a rotating mechanism, the rotating mechanism including a rotatable rotating tube, the rotating tube being rotatably connected to a limit ring; a stripping mechanism, the stripping mechanism being fixedly mounted on one side of the rotating mechanism, the stripping mechanism including a first turntable, one side of the first turntable being fixedly connected to a limit seat, the limit seat being threadedly connected to a screw. This device has the advantage of strong applicability and solves the problem that the existing high-voltage cable joint stripping, cutting and grinding integrated automated system, when processing cables of different diameters, uses an automatically driven rotating mechanism, stripping mechanism and grinding mechanism to perform stripping and grinding, which is not convenient for adjusting the stripping and grinding size at any time, and is prone to errors in the stripping and grinding process, resulting in excessive stripping and grinding, affecting the subsequent wiring of the cable joint. However, the cutter of the stripping mechanism of this equipment still has the risk of stripping the battery cell during the rotation process, and after the stripping is completed, the stripping mechanism needs to be adjusted to the original state, and then the grinding mechanism needs to be moved to the position where grinding is required, which is inefficient.

[0011] Furthermore, the wire stripping mechanism also includes a first forward and reverse screw rod, and the two clamping blocks are movably mounted on the first forward and reverse screw rod.

DETAILED DESCRIPTION

[0028] Unless otherwise defined, all technical and / or scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the invention pertains. It should be understood that certain features of the present invention (described in the context of separate embodiments for clarity) may also be provided in combination in a single embodiment. On the contrary, a plurality of features of the present invention (described in the context of a single embodiment for brevity) may also be provided separately or in any suitable combination or in any other described embodiment of the present invention when appropriate. Certain features described in the context of various embodiments will not be considered as essential features of those embodiments unless the embodiment is inoperable without those elements. The present invention will be further described below by specific examples, but it should be noted that the specific process conditions and results described in the embodiments of the present invention are only used to illustrate the present invention and cannot limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and substance of the present invention should be included within the scope of protection of the present invention.

[0029] The present invention provides an electric cable stripping and polishing device, comprising a driving mechanism, a wire stripping mechanism and a polishing mechanism, and also comprising a fixed disk 1 and a first tray 2 and a second tray 3 rotatably mounted on opposite sides of the fixed disk 1, the driving mechanism and the wire stripping mechanism being mounted on the first tray 2, and the polishing mechanism being mounted on the second tray 3; the driving mechanism being used to drive the first tray 2 and the second tray 3 to rotate synchronously, and to drive the wire stripping mechanism and the polishing mechanism to perform synchronous rotational motion; the wire stripping mechanism being used to clamp the cable and control its travel distance, and at the same time being used to position the relative position of the wire stripping mechanism and the cable core so as to rotationally strip the cable; the polishing mechanism being used to polish the outer surface of the stripped cable that has traveled to the polishing area.

[0030] Further, if Figure 1 、 Figure 2 and Figure 3 As shown, the fixed disk 1 of the present application can specifically be an open gear disk, which is equipped with multiple bearings, multiple series 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 in operation, the drive mechanism connects to the gear disk via its main shaft, inputting power into the gear disk. The gear disk transmits the rotational motion to the adjacent driven gear set through the meshing of its tooth profile, forming a mechanical energy transmission path, thereby forming continuous rotation of multiple series gear sets in the gear disk, and then driving the first tray 2 and the second tray 3 to perform synchronous rotational motion. During this process, the gear disk of the present application always remains fixed and its transmission is highly stable.

[0031] Furthermore, the present application has a mounting support 4 fixedly connected below the fixed plate 1, and the fixing methods include but are not limited to welding, screw connection and hinge, etc. An insulating rod is independently set up in the use site of the device of the present application. The present application connects the insulating rod by installing the support 4, and uses the device and the insulating rod in combination to ensure that the device as a whole meets the insulation requirements and complies with the safety regulations of the power industry, so as to avoid the metal stripping mechanism causing a short circuit due to contact with conductors of different potentials during the live wire stripping process. The present application blocks the current conduction path by connecting the insulating rod to the mounting support 4, thereby reducing the risk of discharge and arc burns.

[0032] Furthermore, the present application utilizes a wire stripping mechanism to strip off the protective layer and insulation layer on the outer surface of the cable to expose the internal battery core, which is convenient for operations such as wire connection, welding or terminal crimping. The wire stripping mechanism of the present application specifically has a positioning function, which can avoid damaging the internal battery core by accurately positioning the wire stripping, such as causing broken strands or scratches, thereby ensuring the conductivity and mechanical strength of the cable battery core. The present application utilizes a grinding mechanism to remove the oxide layer or residual insulation debris on the surface of the battery core, making the outer surface of the battery core smoother, reducing the contact resistance of the connection part, and avoiding local overheating; the surface of the cable battery core is cleaner through grinding, which can improve the strength of the solder joints or the adhesion of the crimped terminals, and ensure the stability of current transmission. The wire stripping and grinding of the present application form a coherent process chain. The former solves the need to expose the battery core, and the latter optimizes the surface state of the battery core. The two together ensure the reliability, safety and long-term stability of the cable battery core connection.

[0033] Furthermore, the stripping mechanism includes two clamping blocks 22 mounted on the first tray 2 in the direction of cable travel. The clamping surfaces of the clamping blocks 22 have a threaded structure. The threaded clamping blocks 22 (not shown) in this application can precisely control the travel distance of the clamped cable through their thread characteristics. The travel distance can be precisely adjusted by controlling the number of thread rotations. The inclined friction characteristics of the thread pair provide a self-locking function, automatically maintaining the current position after stopping rotation, preventing cable displacement caused by external vibration or load changes. Specifically, when the cable of the present application 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 efficient conversion of the rotational motion of the clamping block 22 to the linear motion of the cable. For each rotation of the clamping block 22, the distance the cable moves along its axis is equal to the pitch of the threaded structure. For example, the pitch of the threaded structure of the present application is 0.5mm, and the clamping block 22 rotates 2 circles, which can push the cable to move 1mm in the direction of its travel. Furthermore, the clamping surface of the clamping block 22 of the present application is a concave arc with a threaded structure. The curvature of the concave arc 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 specifications of the clamping block 22 are set according to actual use requirements and cable travel distance requirements. Specifically, the clamping block 22 of the present application is equipped with a clamping bracket 21, multiple support frames 24, multiple mounting plates and multiple screws, so that the two clamping blocks 22 are fixedly connected to the first tray 2 through the above components.

[0034] Further, if Figure 3As shown, the wire stripping mechanism also includes a first forward and reverse screw rod 23, and two clamping blocks 22 are movably mounted on the first forward and reverse screw rod 23. The first forward and reverse screw rod 23 is rotatably mounted in the wire stripping mechanism and can adjust the distance between the two clamping blocks 22 through its rotational movement. The driving mechanism of the present application includes a first motor 5, a second motor 6 and a third motor 7. The first motor 5 is a power motor for rotating the entire device. It can be a two-phase motor, a three-phase motor and a stepping motor, etc. The first motor 5 is mounted on the first tray 2 to provide power for the rotation of the first tray 2 and the second tray 3. The second motor 6 is mounted on the clamping block 22 to provide power for the first forward and reverse screw rod 23. The same shaft of the first forward and reverse screw rod 23 of the present application is machined with left-handed and right-handed threads. When the first forward and reverse screw rod 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 accurately adjusting the distance between the two so that the distance matches the diameter of the cable, thereby completing the clamping of the cable. Furthermore, when the first motor 5 of the present application is running, it can synchronously realize three movements, including driving the clamping block 22 and the first tray 2 to rotate, and on the basis of the rotational movement of the clamping block 22, pushing the cable to perform a linear displacement in its travel direction, and driving the second tray 2 to drive the grinding mechanism to rotate to grind the stripped cable.

[0035] Further, if Figure 1 and Figure 3 As shown, the wire stripping mechanism also includes a cutter 26 assembly mounted along the cable 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 motion. The cutter 26 assembly also includes multiple mounting plates and a support frame 24, a cutter screw 28, and a cutter brush motor 29. Furthermore, the present application utilizes multiple mounting plates and screws to assemble the rotating base 25, the cutter screw 28, and the cutter brush motor 29 and connect them to the clamping block 22. The cutting edge of the cutter 26 in the present application has an arc-shaped structure. This arc-shaped blade contacts the cable surface through a continuous curve, evenly distributing the cutting force along the tangential direction. Compared to traditional straight cutting edges, this reduces most of the local stress concentration and can reduce the wear of the cutter 26. The top of the cutter 26 in the present application has an arc-shaped chip breaker structure, which can accelerate the curling and deformation of the chips, effectively preventing the chips from entanglement and affecting the normal operation of the equipment. In addition, the cutter 26 of the present application can produce a progressive cutting effect when performing high-speed wire stripping. Combined with the drive of the brush motor 29, high-frequency wire stripping stability and high wire stripping integrity can be achieved.

[0036] Furthermore, the present invention's screwdriver 28, driven by a brushed motor 29, can achieve high-precision displacement, effectively compensating for positional deviations of the cutter 26 caused by diameter fluctuations during cable stripping. The screw drive of the screwdriver 28 converts the rotation of the brushed motor 29 into linear displacement of the cutter 26, ensuring minimal error in stripping depth. Furthermore, the present invention's rotating base 25, driven by the brushed motor 29, dynamically adjusts the contact angle between the cutter 26 and the cable, achieving a multi-angle variable cutting angle, for example, from 15° to 65°.

[0037] Further, if Figure 1 As shown, the wire stripping mechanism also includes a positioning member 27 installed on the rotating base 25 for positioning the relative position of the wire stripping mechanism and the cable core. The positioning member 27 is an infrared sensor and / or an electrical sensor. The positioning member 27 of the present application can be fixed in the rotating base 25 by welding, hinged, screw connection and bonding. The infrared sensor of the present application is an active infrared sensor, which includes a transmitting module and a receiving module. When the positioning member 27 is an infrared sensor, it emits 940nm wavelength infrared light to detect the change in the reflected signal when the blade of the cutter 26 contacts the core, and measures the distance between the cutter 26 and the core in real time to provide accurate anti-overcut protection for cable stripping. When the positioning member 27 is an electrical sensor, the blade of the cutter 26 contacts the battery cell, and the conductive characteristics of the battery cell cause a sudden change in the surrounding electromagnetic field. The induction probe of the electrical sensor captures the change in magnetic field strength in real time, and generates a microvolt voltage signal through coil induction. The electrical sensor achieves a millisecond-level response at the moment the blade contacts the battery cell through the synergistic effect of electromagnetic field mutation perception and pulse current characteristic analysis, providing reliable safety protection for live wire stripping.

[0038] Further, if Figure 1 、 Figure 2 and Figure 3 As shown, the device also includes a chip box 9 connected to the stripping mechanism for collecting cable scraps. The chip box 9 is assembled with the cutter 26 assembly to collect all cable scraps removed by the cutter 26, reducing the risk of scraps being scattered and preventing them from entering the air or polluting the factory environment. The device does not specify the shape or size of the chip box 9; it can be configured as needed, such as a rectangular chip box 9.

[0039] Furthermore, a pressing sheet (not shown in the figure) is installed in the chip box 9 of the present application. The pressing sheet of the present application can compress the loose cable scraps entering the chip box 9 into blocks by mechanical pressure to reduce their volume. In addition, the surface structure of the pressing sheet can be designed, such as by setting a staggered groove texture on the surface, to suppress the rebound expansion of the compressed cable scraps and the flying of the cable scraps, which would affect the normal operation of the equipment.

[0040] Further, if Figure 2 and Figure 4 As shown, the grinding mechanism includes a mounting base 31, a second forward and reverse screw 32 and two grinding blocks 33. The two grinding blocks 33 are movably mounted on the second forward and reverse screw 32 at intervals and are mounted in the mounting base 31 through the second forward and reverse screw 32. The second forward and reverse screw 32 can rotate in the mounting base 31 to adjust the distance between the two grinding blocks 33. The mounting base 31 of the present application includes multiple mounting substrates, multiple screws, a series gear set, multiple bearings and multiple mounting covers. The multiple mounting substrates, multiple bearings and multiple mounting covers are assembled together by 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 of the present application is mounted in the mounting base 31, and its bearing is connected to the series gear set. When the third motor 7 is running, it is used to drive the series gear set to rotate, thereby driving the second forward and reverse screw 32 movably connected to the series gear set to rotate. The same shaft of the second forward and reverse screw rod 32 of the present application is processed with left-handed and right-handed threads. When the second forward and reverse screw rod 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 accurately adjusting the distance between the two 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, a grinding brush head array 331 with an arc-shaped structure is provided in the grinding block 33. The grinding brush head array 331 of the present application includes a number of grinding brush heads, and the material of the grinding brush head is selected according to the performance of the oxide layer on the outer surface of different battery cells. For example, the material of the grinding brush head can be high-density nylon bristles, which have excellent wear resistance and can withstand repeated friction on the surface of the metal battery cell, and the flexibility reaches Shore hardness 70A to 85A, which can not only remove the oxide layer but also avoid damaging 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 the grinding operation. Furthermore, the grinding brush heads of the present application all have a certain inclination angle, which is set according to actual needs, such as 10° to 30°. The present application uses an inclined grinding brush head to form a tangential contact with the surface of the battery cell, so that the friction per unit area is increased, and the oxide layer and metal burrs on the outer surface of the battery cell are effectively removed. The angle compensates for the torsional stress of the cable battery cell through the angle to avoid the battery cell rotating during the grinding process and causing partial area leakage. In addition, the inclined grinding brush head of the present application can cover any part of the battery cell at the same time to reduce the difference in grinding depth of different parts of the battery cell. The arc-shaped brush head arrangement of the grinding brush head array 331 of the present application can form a continuous gradient pressure zone on the contact surface, reduce the risk of stress concentration, and automatically adapt to the curvature of the surface of the cylindrical cable battery cell to avoid fatigue damage to the battery cell caused by local overload; In addition, the arc-shaped structure of the grinding brush head array 331 of the present application generates centripetal force compensation when the grinding mechanism rotates at high speed, ensuring that each grinding brush head maintains a constant contact depth with the outer surface of the battery cell, for example, 0.1mm to 0.3mm.

[0042] Furthermore, a power supply assembly mounted on the first tray 2 for providing power to the drive mechanism is included. The power supply assembly in this application can be a battery 8, such as a set of 8 lithium manganese iron phosphate batteries, 8 nickel-cadmium batteries, or 8 lithium thionyl chloride batteries, which have the advantages of high power output, good stability, and durability, and are suitable for industrial applications of the equipment.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
