Description
Technical Field
[0001] This utility model relates to the field of notebook computer wire harness processing technology, and in particular to a wire harness stripping device. Background Technology
[0002] Laptop wiring harnesses are crucial integrated circuit systems that connect the various internal functional components, enabling data transmission and power supply; they can be considered the "nerve lines" of a laptop. They are carefully composed of multiple wires of different specifications and purposes. These wires are typically wrapped in an insulating, wear-resistant, and flexible material to effectively prevent signal interference and short circuits within the complex and confined space of a laptop, while also withstanding the bending and vibrations of daily use. The wiring harness precisely connects the motherboard, processor, memory, hard drive, graphics card, display, keyboard, touchpad, battery, and various interfaces (such as USB, HDMI, and power connectors), ensuring stable and efficient data exchange and power transmission between these components. This allows the laptop to run various programs smoothly, display clear images, and achieve convenient human-computer interaction, making it an indispensable core component for the normal operation of a laptop.
[0003] Utility model patent CN221508954U discloses a wire harness processing stripping device, including a base. A fixing and adjusting mechanism is provided on the top of the base. The fixing and adjusting mechanism includes a slide rail fixedly installed to the top of the base. A worktable is slidably connected to the top of the slide rail. A pull rod is fixedly installed on the front of the worktable. Fixing screws are threaded to both sides of the worktable. A mounting plate is rotatably connected to one side of each fixing screw. This wire harness processing stripping device, through the fixing and adjusting mechanism, uses the fixing screws to move the mounting plate and clamping sleeve until the mounting plate and clamping sleeve move closer together to clamp and fix the wire harness body. This facilitates clamping, fixing, loosening, and disassembling of wire harnesses of different sizes. An electric push rod drives the stripping assembly to move up and down, and a pull rod drives the worktable to slide back and forth on the slide rail, which helps improve the device's adjustable stripping function, increasing the device's flexibility and practicality.
[0004] However, in practical applications, existing wire harness stripping devices still have a series of obvious technical limitations. Specifically, existing devices lack a rapid adaptive adjustment mechanism when dealing with different specifications of laptop wire harnesses, resulting in complex operations and long adjustment times when changing wire harness models, seriously affecting overall processing efficiency. Furthermore, the device lacks an effective wire harness take-up and undo structure, which easily causes wire harness tangling or uneven tension during stripping, thus affecting stripping accuracy and even damaging the wire core, reducing yield. Simultaneously, due to the lack of a unified guiding and positioning design, the stripping blade is prone to deviation during movement, leading to inconsistent stripping depth and further affecting product quality. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative wire harness processing stripping device to solve these problems. Utility Model Content
[0005] The purpose of this utility model is to provide a wire harness processing stripping device, which solves the problem that the existing technology lacks a quick and adaptable adjustment mechanism when dealing with different specifications of laptop wire harnesses, resulting in complicated operation and long adjustment time when changing wire harness models, which seriously affects the overall processing efficiency. In addition, the lack of an effective wire harness take-up and release structure makes it easy for the wire harness to become tangled or unevenly tensioned during the stripping process, which in turn affects the stripping accuracy and may even damage the wire core, reducing the yield.
[0006] To achieve the above objectives, this utility model provides a wire harness processing stripping device, including a frame, and side plates fixedly connected to both sides of the inner side of the frame, with a bearing cylinder provided between the two side plates;
[0007] Two cylinders are bolted to opposite sides of the two side plates, and cutters are provided on both sides of the inner side of the bearing cylinder. The output shafts of the two cylinders pass through the two side plates and both sides of the bearing cylinder in sequence. The output shafts of the two cylinders are fixedly connected to one side of the two cutters respectively. Bearing frames are fixedly connected to both sides of the frame, and a first bearing rod is rotatably connected to one side of the inner side of each of the two bearing frames. A second bearing rod is rotatably connected to the other side of the inner side of each of the two bearing frames. A winding rod is detachably connected between the first and second bearing rods, and one end of the two second bearing rods is connected by a belt winding.
[0008] One side of one of the two load-bearing frames is fixedly connected to a drive motor by bolts, and one end of one of the two second load-bearing rods is connected to the output shaft of the drive motor.
[0009] Each of the two second bearing rods has a pulley fitted onto one end, and the two pulleys are connected by a belt winding around each other.
[0010] Both ends of the two winding rods are fixedly connected to one end of the two first bearing rods and one end of the two second bearing rods by bolts. One end of the two first bearing rods is rotatably connected to the inner wall of the two bearing frames by a rotating shaft, and one end of the two second bearing rods passes through the side wall of the two bearing frames by a bearing sleeve.
[0011] The bearing cylinder has arc-shaped bearing plates on both sides, and the bottom of the two arc-shaped bearing plates is fixedly connected to the bottom of the inner side of the frame through telescopic rods.
[0012] Both telescopic rods are fitted with compression springs, and the bottom of the arc-shaped support plate is elastically connected to the inner bottom of the frame through the compression springs.
[0013] This utility model discloses a wire harness stripping device. By using a cylinder to drive the cutter, it achieves rapid adjustment of wire harnesses of different diameters without changing fixtures or manually adjusting multiple components, greatly shortening changeover time and improving equipment adaptability and work efficiency. Addressing the issue of inconvenient wire harness unwinding and rewinding, this utility model introduces a detachable unwinding and rewinding structure composed of a first support rod, a second support rod, and a winding rod, combined with a belt drive mechanism. This enables stable wire unwinding and rewinding control during stripping, effectively avoiding problems such as wire harness tangling, knotting, and tension fluctuations, thereby improving the consistency of stripping quality and yield. Furthermore, the positioning and cooperation between the support cylinder and the cutters on both sides ensures the stability of the stripping cutter's running path, reducing the cutter deviation phenomenon common in traditional devices, further ensuring the consistency of stripping depth and improving processing accuracy. Overall, this device not only has a reasonable structural design and convenient operation, but also significantly improves the work efficiency and processing quality of laptop computer wire harness stripping, meeting the production needs of modern manufacturing for high efficiency, high consistency, and multi-specification compatibility, and has good application prospects and promotional value.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0022] Please see Figure 1-5 A wire harness stripping device includes a frame 1, and side plates 8 are fixedly connected to both sides of the inner side of the frame 1, with a bearing cylinder 9 between the two side plates 8. Cylinders 11 are fixedly connected to the opposite sides of the two side plates 8 by bolts. Cutters 10 are provided on both sides of the inner side of the bearing cylinder 9. The output shafts of the two cylinders 11 pass through both sides of the two side plates 8 and the bearing cylinder 9 in sequence. The output shafts of the two cylinders 11 are fixedly connected to one side of the two cutters 10 respectively. Bearing frames 2 are fixedly connected to both sides of the frame 1. A first bearing rod 3 is rotatably connected to one side of the inner side of the two bearing frames 2, and a second bearing rod 15 is rotatably connected to the other side of the inner side of the two bearing frames 2. A winding rod 4 is detachably connected between the first bearing rod 3 and the second bearing rod 15. One end of the two second bearing rods 15 is wound together by a belt 7.
[0023] First, the wire harness that needs to be stripped is removed from one of the winding rods 4 and passed through the internal space of the carrier cylinder 9. Then, the other end of the wire harness is connected to and fixed to another winding rod 4. Next, the two cylinders 11 are activated, and their output shafts drive the cutter 10 to move inward through the structure that passes through the side plate 8 and the carrier cylinder 9. The distance between the two cutters 10 is adjusted according to the specific diameter of the wire harness to achieve adaptive cutting for wire harnesses of different specifications. After the cutter 10 is in position, the outer insulation of the wire harness passing through the carrier cylinder 9 is cut and stripped. At the same time, the two second carrier rods 15 drive the two winding rods 4 to rotate synchronously through the transmission action of the belt 7, realizing the automatic wire feeding and the winding of the stripped metal core wire. The whole process is completed under the condition that the wire harness tension is kept relatively stable, avoiding uneven stripping or core wire damage caused by uneven tension.
[0024] Furthermore, one side of one of the two support frames 2 is fixedly connected to a drive motor 5 by bolts, and one end of one of the two second support rods 15 is connected to the output shaft of the drive motor 5. When the drive motor 5 is started, it drives the second support rod 15 to rotate, thereby realizing the automatic rotation of the winding rod 4. This achieves the effect of improving the degree of automation, reducing the need for manual operation, and improving work efficiency and stability.
[0025] Furthermore, each of the two second bearing rods 15 is fitted with a pulley 6 at one end, and the two pulleys 6 are connected by a belt 7. When the drive motor 5 drives one of the second bearing rods 15 to rotate, the other second bearing rod 15 is driven to rotate synchronously through the action of the belt 7 and the pulley 6. This ensures that the two winding rods 4 can coordinate and perform the wire feeding and winding actions, thereby ensuring uniform tension of the wire harness and avoiding the problem of unstable stripping quality due to uneven tension.
[0026] Furthermore, both ends of the two winding rods 4 are fixedly connected to one end of the two first bearing rods 3 and one end of the two second bearing rods 15 respectively by bolts. One end of the two first bearing rods 3 is rotatably connected to the inner wall of the two bearing frames 2 through a rotating shaft, and one end of the two second bearing rods 15 passes through the side wall of the two bearing frames 2 respectively through a bearing sleeve. This design makes it simple and quick to replace winding rods 4 of different specifications or lengths, while ensuring the stability of the winding rods 4 during rotation. It achieves the purpose of facilitating quick adjustment to adapt to the processing needs of wire harnesses of different sizes, and enhances the flexibility and applicability of the device.
[0027] Furthermore, both sides of the bearing cylinder 9 are provided with arc-shaped bearing plates 12, and the bottom of the two arc-shaped bearing plates 12 are fixedly connected to the bottom of the inner side of the frame 1 through the telescopic rod 13. During the process of the wire harness passing through the bearing cylinder 9, the arc-shaped bearing plates 12 can automatically adjust their position according to the diameter of the wire harness, provide appropriate support, and prevent the wire harness from shifting during the cutting process, thereby achieving the effect of enhancing cutting accuracy and reducing the risk of core wire damage.
[0028] Furthermore, each of the two telescopic rods 13 is fitted with a compression spring 14, and the bottom of the arc-shaped support plate 12 is elastically connected to the bottom of the inner side of the frame 1 through the compression spring 14. The presence of the compression spring 14 allows the arc-shaped support plate 12 to adaptively adjust the pressure according to the different thicknesses of the wire harness, which not only ensures good support for the wire harness, but also avoids excessive compression that could cause deformation or damage to the wire harness, thus achieving the effect of optimizing wire harness positioning and improving stripping quality.
[0029] In summary:
[0030] First, the laptop wiring harness that needs to be stripped is removed from one of the winding rods 4 and passed through the internal space of the carrier cylinder 9. Then, the other end of the wiring harness is connected and fixed to another winding rod 4. Next, two cylinders 11 are activated, and their output shafts drive the cutter 10 to move inward. The distance between the two cutters 10 is adjusted according to the specific diameter of the wiring harness to accommodate the stripping requirements of different specifications of wiring harnesses. After the cutter 10 is in position, the outer insulation layer of the wiring harness passing through the carrier cylinder 9 is cut and stripped. At the same time, the drive motor 5 is set on one side of one of the carrier frames 2 and fixed with bolts. Its output shaft is connected to a second carrier rod 15. After the motor is started, it drives the second carrier rod 15 to rotate. Then, through the linkage of the pulley 6 and the belt 7, the two second carrier rods 15 rotate synchronously, thereby driving the two winding rods 4 to realize the automatic wire feeding and stripped metal core wire winding action. Throughout the process, the wiring harness maintains a relatively stable tension state to avoid uneven stripping or core wire damage caused by uneven tension. In addition, both ends of the winding rod 4 are fixedly connected to one end of the two first bearing rods 3 and the two second bearing rods 15 respectively by bolts. One end of the two first bearing rods 3 is rotatably connected to the inner wall of the bearing frame 2 through a rotating shaft, and one end of the two second bearing rods 15 passes through the side wall of the bearing frame 2 respectively through bearing sleeves. This detachable connection method makes it simple and quick to replace winding rods 4 of different lengths or specifications, while ensuring the stability of the winding rod 4 during rotation. It is convenient to quickly adapt to the processing requirements of wire harnesses of different sizes, and improves the flexibility and applicability of the equipment. To further improve stripping accuracy, arc-shaped support plates 12 are provided on both sides of the support cylinder 9. The bottom of the two arc-shaped support plates 12 is fixedly connected to the inner bottom of the frame 1 through a telescopic rod 13, and a compression spring 14 is sleeved on the telescopic rod 13 to form an elastic connection between the arc-shaped support plates 12 and the frame 1. During the process of the wire harness passing through the support cylinder 9, the arc-shaped support plates 12 can adaptively move up and down according to the diameter of the wire harness. With the elastic support of the telescopic rod 13 and the compression spring 14, appropriate support pressure is provided to prevent the wire harness from shifting or being over-compressed during the cutting process, thereby effectively enhancing the cutting accuracy, reducing the risk of core wire damage, optimizing the wire harness positioning effect, and improving the stripping quality.The movement of the cutter 10 driven by the cylinder 11 enables rapid adjustment of wire harnesses of different diameters, solving the problem of "inconvenience in stripping wire harnesses of different specifications" in the prior art, and improving work efficiency and equipment adaptability. The synchronous transmission system composed of the drive motor 5, pulley 6, and belt 7 ensures stable wire feeding and take-up control during the stripping process, solving the problem of inconvenience in wire harness feeding and take-up, and improving processing consistency and yield. The detachable connection design between the winding rod 4 and the first and second support rods 3 and 15 enhances the compatibility of the device with various wire harness specifications and improves the convenience and flexibility of use. The combination structure of the arc-shaped support plate 12, telescopic rod 13, and compression spring 14 on both sides of the support cylinder 9 effectively improves the positioning accuracy and force balance of the wire harness during the cutting process, reduces the possibility of core wire damage, further ensures the consistency of stripping depth, and improves the overall processing quality. The device has a reasonable structure and is easy to operate, which significantly improves the efficiency and processing accuracy of stripping wire harnesses for laptops. It meets the production needs of modern manufacturing industry for high efficiency, high consistency and multi-specification compatibility, and has good application prospects and promotion value.
