Description

Technical Field

[0001] This invention relates to the field of wire and cable processing technology, and in particular to a desktop fixed wire stripper. Background Technology

[0002] In the production and repair process of wires and cables, wire stripping is a fundamental and crucial step, and its quality and efficiency directly affect the smooth progress of subsequent processes. Currently, when stripping multi-strand wires manually using a utility knife, the process relies entirely on hand strength control, which easily leads to uneven cutting depth, tilting, and other problems. This can not only result in insulation residue or damage to the battery core, but also create safety hazards due to insufficient operational precision, seriously restricting the stability of product quality.

[0003] Existing wire stripping equipment, such as patents CN105322470B and CN205544007U, while replacing manual labor to some extent, still has significant limitations: For cables of different diameters, frequent replacement of suitable stripping components is required, which is not only cumbersome but also consumes a significant amount of time, significantly reducing production efficiency; during the stripping process, the cable positioning mechanism lacks stability and is prone to axial or radial displacement, resulting in poor flatness and inconsistent stripping depth, directly affecting the quality of subsequent crimping and conduction processes; furthermore, after stripping, the cable's internal core is difficult to separate from the outer sheath quickly, and existing equipment lacks an efficient separation structure, requiring manual disassembly one by one, which increases the labor intensity of workers and further slows down the overall operation due to inconsistencies in manual operation.

[0004] Therefore, developing a desktop fixed wire stripper that is simple in structure, easy to operate, adaptable to cables of different diameters, and has both precise wire stripping and rapid separation of battery cells has become an urgent need to solve the current pain points in the industry. Summary of the Invention

[0005] To address the technical problems existing in the background art, the present invention proposes a desktop fixed wire stripper.

[0006] The present invention proposes a desktop fixed wire stripper, including a vertical plate, wherein the upper and lower parts of the inner side of the vertical plate are respectively provided with a wire stripping mechanism and a positioning mechanism; The wire stripping mechanism includes side plates symmetrically arranged on both sides of the upright plate. A rotating shaft and a rotating roller are rotatably connected between the two sets of side plates. The rotating shaft is provided with multiple sets of circular cutters. The side wall of the rotating roller is provided with multiple sets of annular slots. The circular cutters correspond one-to-one with the slots and are directly opposite each other. The upright plate is provided with multiple sets of through holes. The through holes correspond one-to-one with the slots and are distributed in a gradient size. The rotating roller and the rotating shaft are linked by a gear transmission assembly. The side plate is provided with a first driving member for driving the rotating roller to rotate. The positioning mechanism includes multiple sets of support plates vertically fixed to the upright plate, and a clamping plate located below the support plates. The clamping plate is connected to the upright plate via a vertical adjustment component to adjust the distance between it and the support plates. Two sets of side plates have protrusions on the side away from the upright plate. A crossbeam connects the two sets of protrusions. A moving block is slidably connected to the crossbeam. A partition plate is provided at the bottom of the moving block. A boss is provided on one side of the moving block. A lifting platform is connected to the bottom of the boss via a telescopic component. A first shovel plate and a second shovel plate, arranged in a V-shape, are slidably connected to the bottom of the lifting platform. The sliding direction of the first and second shovel plates is parallel to the crossbeam. A separation adjustment component is provided on the lifting platform to drive the first and second shovel plates to move relative to each other. Preferably, the first driving component is a first motor, the output end of which is connected to the rotating roller. The gear transmission assembly includes a first gear mounted on one side of the rotating roller and a second gear mounted on one side of the rotating shaft, with the first gear meshing with the second gear. Using a first motor as the driving component provides stable and controllable power to the rotating roller, ensuring uniform roller rotation speed and preventing a decrease in cutting accuracy due to unstable power during wire stripping. Furthermore, the meshing of the first and second gears enables linkage between the rotating roller and the rotating shaft, resulting in high transmission efficiency and a simple structure. This ensures synchronized movement of the circular cutter and the roller's groove, further improving the accuracy and consistency of wire stripping. Preferably, the vertical adjustment component is a screw-nut mechanism, including a drive source, a vertical screw, and a nut block. The drive source is mounted on the vertical plate, the vertical screw is connected to the output end of the drive source, and the nut block is threadedly connected to the vertical screw and fixed to the clamping plate. The screw-nut mechanism features high transmission accuracy and good self-locking performance. By driving the vertical screw to rotate through the drive source, the height of the nut block and the clamping plate can be precisely adjusted, thereby accurately controlling the distance between the clamping plate and the support plate. This adapts to the positioning requirements of cables of different diameters, and the distance can be stably maintained after adjustment, preventing the cable from loosening or shifting during stripping. Preferably, the crossbeam has multiple sets of limiting grooves, each set corresponding to a through hole. The moving block has a telescopic cavity, with sliding grooves at both the top and bottom. Both sets of sliding grooves are perpendicular to the crossbeam, and sliders are slidably connected to each set. A spring is connected to the sidewall of the slider and the end of the sliding groove away from the crossbeam. A cylindrical rotating cylinder connects the two sets of sliders, with its sidewall movably engaged with each sliding groove. The one-to-one correspondence between the limiting grooves and through holes on the crossbeam, combined with the engaging structure of the rotating cylinder and sliding groove on the moving block, allows for precise positioning of the moving block on the crossbeam, ensuring that the positions of the separator, the first shovel, and the second shovel correspond to the cables to be processed. The springs provide elastic pressure to the rotating cylinder, ensuring stable engagement between the rotating cylinder and the limiting groove, while also allowing the moving block to be flexibly adjusted as needed, resulting in convenient operation and reliable positioning. Preferably, the vertical adjustment component is a screw-nut mechanism, including a drive source and a vertical screw. The drive source is mounted on a boss, the vertical screw is connected to the output end of the drive source, the vertical screw is threadedly connected to the lifting platform, and the lifting platform is slidably connected to the side wall of the moving block. This screw-nut mechanism can drive the vertical screw to rotate through the drive source, precisely adjusting the height of the lifting platform, thereby controlling the contact distance between the first and second shovel plates and the cable. The slidable connection between the lifting platform and the side wall of the moving block ensures the stability of the lifting process, prevents the shovel plates from shaking, ensures the accuracy of the cell separation operation, and adapts to different cable height requirements after stripping. After the first and second shovel plates separate the outer sheath, they push downwards past the internal cell and then close together, separating the first and second shovel plates between the cell and the outer sheath. Preferably, the separation adjustment assembly includes two sets of grooves located at the bottom of the lifting platform. A first sliding block and a second sliding block are respectively provided in the two sets of grooves. The first sliding block is connected to a first shovel plate, and the second sliding block is connected to a second shovel plate. A transverse lead screw, a first lead screw and a second lead screw, are respectively provided in the two sets of grooves. The first lead screw is threadedly connected to the first sliding block, and the second lead screw is threadedly connected to the second sliding block. A second driving component is provided on the lifting platform, driving the first and second lead screws to rotate synchronously in opposite directions via a bevel gear transmission assembly. By driving the first and second lead screws to rotate synchronously in opposite directions via the bevel gear transmission assembly, the first and second sliding blocks can precisely move the first and second shovel plates relative to each other, achieving uniform separation of the battery cells. The grooves provide a stable sliding track for the sliding blocks, ensuring the smooth movement of the shovel plates and improving the efficiency and effectiveness of battery cell separation. Preferably, the bevel gear transmission assembly includes a transmission shaft connected to the output end of the second drive member. The transmission shaft is equipped with a first bevel gear and a second bevel gear. The ends of the first and second lead screws are respectively equipped with a third bevel gear and a fourth bevel gear. The first bevel gear meshes with the fourth bevel gear, and the second bevel gear meshes with the third bevel gear. The bevel gear transmission assembly enables power transmission in the vertical direction, has a compact structure, and provides smooth transmission. It ensures that the first and second lead screws rotate precisely in opposite directions synchronously under the drive of the second drive member, thereby ensuring coordinated movement of the first and second shovel plates and improving the synchronization and accuracy of cell separation. Preferably, the first and second shovel plates are symmetrically inclined, forming a V-shaped structure in side view, and their bottoms are collinear with the vertical projection of the separator plate. The V-shaped shovel plates can better conform to the distribution pattern of the multi-strand battery cells, and can apply a uniform separation force from both sides of the battery cells during relative movement, avoiding damage to the battery cells. The collinearity of the bottom with the vertical projection of the separator plate ensures that the separator plate and the shovel plates work together, with the separator plate initially widening the gap, and then the shovel plates further separating the cells, improving the overall separation effect. Preferably, the multiple sets of through holes are distributed in a straight line along the horizontal direction, and their size gradient matches that of the slots. This straight-line distribution and consistent size gradient between the through holes and slots facilitates quick selection of the corresponding through holes and slots by the operator based on the cable diameter, eliminating the need for additional adjustments to the overall structure of the equipment. This improves the equipment's adaptability to cables of different diameters and reduces the time cost of cable replacement operations. Preferably, the maximum distance between the first and second shovel plates driven by the separation adjustment assembly is greater than the diameter of the cable core. This ensures that the shovel plates have sufficient room to move, accommodating the separation needs of different numbers and diameters of cores, and avoiding incomplete separation of cores due to insufficient spacing or damage caused by excessive compression during separation, thus improving the versatility and safety of the equipment.

[0007] This invention presents a benchtop fixed wire stripper, a tool commonly used in electronic assembly and electrical repair. By placing the cable in the appropriate holes of the stripper, its cutting device can easily and quickly strip the insulation layer, exposing the internal conductors, thus improving stripping efficiency and quality. Compared to some manual wire stripping tools, it reduces the risk of operators being cut by sharp tools, and the benchtop fixed design offers greater stability compared to manual methods. By setting multiple sets of through holes, slots, and circular cutters with gradient size distribution, it can adapt to the stripping needs of cables of different sizes, eliminating the need for frequent component replacement and improving work efficiency. By setting multiple sets of through holes and slots of different sizes, it can adapt to cables of different diameters, eliminating the need for frequent adjustment or replacement of cutters and improving the versatility and applicability of the equipment. The stripping mechanism adopts a gear transmission component to link the rotating roller and the rotating shaft, realizing the simultaneous conveying of the cable and the cutting of the outer sheath. The structure is simple and the transmission efficiency is high. The positioning mechanism adjusts the distance between the clamping plate and the support plate through the vertical adjustment component, which can firmly clamp the wire stripper on the workbench of different thicknesses, ensuring the stability of the equipment during the wire stripping process, avoiding the impact of shaking on the wire stripping accuracy, and highlighting the fixed advantage of the benchtop equipment.

[0008] The separation mechanism uses a V-shaped first and second shovel plate, which, together with the widening effect of the partition plate, can automatically separate the cable sheath from the battery core. The battery core is located inside the angle of the V-shaped structure, while the sheath is located outside the angle of the V-shaped structure, eliminating the need for additional manual separation steps and improving work efficiency.

[0011] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0012] like Figures 1-9The tabletop wire stripper shown includes a vertical plate 1. The upper part of the inner side of the vertical plate 1 is provided with a wire stripping mechanism, and the lower part is provided with a positioning mechanism. The vertical plate 1 serves to support and fix the various mechanisms, and the positioning mechanism is used to stably clamp the entire wire stripper on the worktable.

[0013] In the wire stripping mechanism, two sets of side plates 103 are symmetrically arranged on both sides of the upright plate 1. The rotating shaft 3 and the rotating roller 2 are rotatably connected between the two sets of side plates 103 and are distributed vertically. Multiple sets of circular cutters 302 are installed on the rotating shaft 3, and multiple sets of annular grooves 401 are opened on the side wall of the rotating roller 2. The circular cutters 302 correspond one-to-one with the grooves 401 and are directly opposite each other vertically. Multiple sets of through holes 104 are opened through the upright plate 1, distributed in a straight line along the horizontal direction, corresponding one-to-one with the grooves 401 and distributed in a gradient size distribution with consistent size gradient. The dimensions of the multiple sets of circular cutters 302 are adapted to the corresponding through holes 104. The inner diameter of the circular cutter 302 is slightly larger than the inner core diameter of the cable adapted to the corresponding through hole 104, and smaller than the outer protective layer diameter of the cable adapted to the corresponding through hole 104, so as to ensure that only the outer protective layer of the cable is cut during the stripping process without damaging the inner core. The circular cutter 302 is detachable, so that the cutter can be easily replaced when it is rusted or dull.

[0014] The rotating roller 2 and the rotating shaft 3 are linked by a gear transmission assembly, which includes a first gear 201 mounted on one side of the rotating roller 2 and a second gear 301 mounted on one side of the rotating shaft 3. The first gear 201 and the second gear 301 mesh with each other. A first driving member 202 is mounted on the side plate 103. The first driving member 202 is a first motor, and its output end is connected to the rotating roller 2 for driving the rotating roller 2 to rotate.

[0015] Positioning mechanism The positioning mechanism is used to clamp the wire stripper on the workbench. It includes multiple sets of support plates 101 that are vertically fixed to the upright plate 1, and a clamping plate 102 located below the support plate 101. The clamping plate 102 is connected to the upright plate 1 through a vertical adjustment component to adjust the distance between it and the support plate 101 to accommodate workbenches of different thicknesses.

[0016] In this embodiment, the vertical adjustment component is a lead screw and nut mechanism, including a drive source, a vertical lead screw, and a nut block. The drive source is mounted on the vertical plate 1, the vertical lead screw is connected to the output end of the drive source, and the nut block is threadedly connected to the vertical lead screw and fixed to the clamping plate 102. In use, the edge of the worktable is placed between the support plate 101 and the clamping plate 102. The drive source drives the vertical lead screw to rotate, and the nut block moves up and down along the vertical lead screw, thereby causing the clamping plate 102 to rise and cooperate with the support plate 101 to clamp the worktable, thus achieving stable fixation of the wire stripper on the worktable. When the device needs to be moved, driving the clamping plate 102 to descend releases the worktable.

[0017] Separation mechanism Two sets of side plates 103 have protrusions on the side away from the upright plate 1, and a crossbeam 4 connects the two sets of protrusions. A movable block 5 is slidably connected to the crossbeam 4. A partition plate 603 is provided at the bottom of the movable block 5. A boss 501 is provided on one side of the movable block 5. A lifting platform 6 is connected to the bottom of the boss 501 through a telescopic component 604. A first shovel plate 601 and a second shovel plate 602 distributed in a V-shape are slidably connected to the bottom of the lifting platform 6. The sliding direction of the first shovel plate 601 and the second shovel plate 602 is parallel to the crossbeam 4. A separation adjustment component is provided on the lifting platform 6 to drive the first shovel plate 601 and the second shovel plate 602 to move relative to each other.

[0018] In this embodiment, the crossbeam 4 has multiple sets of limiting grooves, each corresponding to a through hole 104. The moving block 5 has a telescopic cavity, with sliding grooves 503 at both the top and bottom. Both sets of sliding grooves 503 are perpendicular to the crossbeam 4, and sliders are slidably connected to each set of sliding grooves 503. A spring 504 is connected to the side wall of the slider and the end of the sliding groove 503 away from the crossbeam 4. A cylindrical rotating cylinder 502 is connected between the two sets of sliders, and the side wall of the rotating cylinder 502 is movably engaged with each sliding groove 503. When the position of the moving block 5 needs to be adjusted, the moving block 5 is moved, and the rotating cylinder 502 is engaged in the limiting groove. The spring 504 keeps the side wall of the rotating cylinder 502 engaged in the limiting groove, thus achieving the positioning of the moving block 5.

[0019] The vertical adjustment assembly is a lead screw and nut mechanism, including a drive source and a vertical lead screw. The drive source is mounted on the boss 501, the vertical lead screw is connected to the output end of the drive source, and the vertical lead screw is threadedly connected to the lifting platform 6. The lifting platform 6 is slidably connected to the side wall of the moving block 5. When the drive source drives the vertical lead screw to rotate, the lifting platform 6 moves up and down along the vertical lead screw, realizing the lifting and lowering of the first shovel plate 601 and the second shovel plate 602.

[0020] The separation adjustment assembly includes two sets of grooves 7 located at the bottom of the lifting platform 6. A first sliding block 707 and a second sliding block 710 are respectively provided in the two sets of grooves 7. The first sliding block 707 is connected to the first shovel plate 601, and the second sliding block 710 is connected to the second shovel plate 602. A transverse lead screw is provided in the two sets of grooves 7, namely a first lead screw 705 and a second lead screw 708. The first lead screw 705 is threadedly connected to the first sliding block 707, and the second lead screw 708 is threadedly connected to the second sliding block 710. A second driving member 701 is provided on the lifting platform 6, which drives the first lead screw 705 and the second lead screw 708 to rotate synchronously in opposite directions through a bevel gear transmission assembly.

[0021] The bevel gear transmission assembly includes a transmission shaft 702 connected to the output end of the second drive member 701. The transmission shaft 702 is equipped with a first bevel gear 703 and a second bevel gear 704. The ends of the first lead screw 705 and the second lead screw 708 are respectively equipped with a third bevel gear 706 and a fourth bevel gear 709. The first bevel gear 703 meshes with the fourth bevel gear 709, and the second bevel gear 704 meshes with the third bevel gear 706. When the second drive member 701 drives the transmission shaft 702 to rotate, the meshing of the first bevel gear 703 with the fourth bevel gear 709, and the meshing of the second bevel gear 704 with the third bevel gear 706, drives the first lead screw 705 and the second lead screw 708 to rotate synchronously in opposite directions. This causes the first sliding block 707 and the second sliding block 710 to move relative to each other, thereby opening and closing the first shovel plate 601 and the second shovel plate 602.

[0022] The first shovel plate 601 and the second shovel plate 602 are symmetrically inclined and have a V-shaped structure when viewed from the side, with their bottoms collinear with the vertical projection of the separator plate 603. This structural design allows the separator plate 603 to be inserted into the cut in the cable sheath first, widening the gap. Then, the first shovel plate 601 and the second shovel plate 602 are inserted into the cut and separated to the sides, peeling the sheath from the battery cell. After the lifting platform 6 descends, the first shovel plate 601 and the second shovel plate 602 come together again. The bottom side of the lifting platform 6, the first shovel plate 601 and the second shovel plate 602 form a closed space, with the separated battery cell located inside this space and the peeled outer wall located outside this space.

[0023] In this embodiment, during operation: Before use, fix the wire stripper on the workbench using the positioning mechanism: according to the thickness of the workbench, activate the vertical adjustment component to drive the clamping plate 102 to rise, so that the support plate 101 and the clamping plate 102 clamp the workbench, ensuring the equipment is stable.

[0024] Select the appropriate through hole 104 and corresponding limiting groove according to the cable diameter, and pass the cable through the through hole 104. Start the first drive unit 202 to drive the roller 2 to rotate, and drive the rotating shaft 3 to rotate synchronously through the gear transmission assembly. The circular cutter 302 cuts a slit in the cable sheath. At the same time, the rotation of the roller 2 and the circular cutter 302 transports the cable forward.

[0025] As the cable continues to be conveyed forward, the separator 603 is precisely inserted into the opening made by the circular cutter 302, widening the gap. For example... Figures 4-7 As shown: The telescopic component 604 drives the lifting platform 6 to descend, allowing the first shovel plate 601 and the second shovel plate 602 to be inserted into the enlarged opening. The second drive component 701 is activated, and the separation adjustment component drives the first shovel plate 601 and the second shovel plate 602 to separate to both sides. During this process, the separation distance is slightly larger than the diameter of the battery cell, which can pry the opening open from both sides to expose the internal battery cell.

[0026] Next, the lifting platform 6 moves downwards a short distance. During this descent, the first shovel plate 601 and the second shovel plate 602 push the separated outer sheath downwards, passing over the battery cell. Then, the first shovel plate 601 and the second shovel plate 602 converge towards the center. At this point, the battery cell is located inside the V-shaped angle formed by the first shovel plate 601 and the second shovel plate 602, while the outer sheath is located outside the V-shape. As the cable continues to be transported, the battery cell and outer sheath automatically separate, with the first shovel plate 601 and the second shovel plate 602 separating the battery cell and outer sheath on opposite sides.

[0027] The desktop fixed wire stripper of the present invention achieves a stable connection with the workbench through a positioning mechanism. It has a simple structure and is easy to operate. It can perform wire stripping operations on cables of different diameters efficiently and accurately. The automatic separation of the cable sheath and the battery core is achieved through the coordinated action of the partition plate 603, the first shovel plate 601 and the second shovel plate 602. It has high practical value and promotion prospects.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
