Abstract
Description
Technical Field
[0001] This application relates to the field of wire harness processing technology, and more specifically, to a core wire separation mechanism. Background Technology
[0002] In industrial production fields such as electronic wire harness processing and electrical connection system assembly, core wire separation is a crucial fundamental process. Scenarios such as automotive wire harness manufacturing, internal wiring of electronic equipment, and electrical control cabinet wiring all require the precise separation of multi-stranded core wires to meet the demands of subsequent processes such as welding, terminal crimping, and plug-in assembly, ensuring the stability and reliability of electrical connections. The quality of this process directly affects the overall performance and lifespan of the product. With the continuous expansion of industrial production scale, increasingly stringent requirements are being placed on the efficiency, precision, and consistency of core wire separation operations.
[0003] In existing technologies, most production scenarios still rely on manual operation to separate the core wires. During manual separation, workers need to use manual tools and rely on experience to pull and arrange the merged core wires one by one. This results in low production efficiency, making it difficult to adapt to the high-speed production rhythm of large-scale assembly lines, limiting production capacity. Furthermore, the accuracy of manual separation is greatly affected by the worker's skill level and fatigue level, resulting in poor consistency in the shape of the separated core wires, easy occurrence of core wire damage, substandard separation angles, and other problems, which in turn increase the defect rate of subsequent processes and raise production costs. Utility Model Content
[0004] To address the aforementioned problems, this application provides a core wire separation mechanism.
[0005] The core wire separation mechanism provided in this application adopts the following technical solution:
[0006] A core wire separation mechanism includes a base plate, a base on the top of the base plate, and a separation component on the top of the base.
[0007] The separation assembly includes a clamping component and a separation component. The clamping component includes two second cylinders. The output ends of the two second cylinders are respectively connected to a first clamping jaw and a second clamping jaw. An adjustable clamping cavity is formed between the first clamping jaw and the second clamping jaw for clamping the core wires respectively.
[0008] The separation component includes a guide rail and two limit blocks slidably disposed thereon. The limit blocks are connected to the corresponding second cylinders via connecting plates to achieve relative movement between the first gripper and the second gripper.
[0009] Through the above technical solutions, the separation component enables rapid separation of the core wire, eliminating reliance on manual operation rhythm and adapting to the high-speed production needs of large-scale production lines. Furthermore, with the control of components such as servo motors and bidirectional threaded rods, parameters such as core wire separation angle and clamping force can be stably set, avoiding fluctuations in separation pattern caused by differences in worker skills and fatigue levels, and reducing core wire damage and substandard angles.
[0010] Furthermore, a servo motor is installed on the top of the base, and two plates are fixedly connected to the top of the base.
[0011] Furthermore, the top of the base is provided with a two-way threaded rod, which is rotatably connected to the two plates.
[0012] Furthermore, the output end of the servo motor is connected to the bidirectional threaded rod via a synchronous belt to drive the bidirectional threaded rod to rotate.
[0013] Furthermore, the outer wall of the bidirectional threaded rod has two sliders, and the two sliders are fixedly connected to the corresponding connecting plates respectively.
[0014] Furthermore, a first cylinder is provided at one end of the base, and a heating gripper is connected to the output end of the first cylinder.
[0015] Through the above technical solution, the heated gripper is driven by the first cylinder to adhere to the part where the core wire is separated. The heating makes the insulation layer and surface material of the core wire enter a plastic state. Combined with heat conduction, shape memory and shaping are achieved, so that the core wire forms a stable Y-shaped structure. This effectively avoids the rebound problem caused by the elasticity of the core wire itself, and ensures the consistency and stability of the shape after separation.
[0016] Furthermore, the heating jaw is located on one side of the first jaw and the second jaw.
[0017] Furthermore, the top of the base is provided with a housing, and one end of the housing has a placement hole for inserting the core wire.
[0018] Furthermore, the placement hole is located on one side of the first gripper and the second gripper.
[0019] Furthermore, the clamping surfaces of the first and second jaws are provided with anti-slip textures to enhance the clamping force on the core wire.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] (1) This utility model achieves rapid separation of the core wire by setting the separation component, gets rid of the dependence on the rhythm of manual operation, can adapt to the high-speed production needs of large-scale assembly lines, and with the help of the control of components such as servo motors and bidirectional threaded rods, parameters such as core wire separation angle and clamping force can be set stably, avoiding the fluctuation of separation form caused by differences in worker skills and fatigue, and reducing the damage to the core wire and the failure of the angle to meet the standard.
[0022] (2) This utility model uses heated grippers and a first cylinder to drive them to adhere to the core wire separation part. Heating makes the core wire insulation layer and surface material enter a plastic state. Combined with heat conduction, shape memory and shaping are achieved, so that the core wire forms a stable Y-shaped structure. This effectively avoids the rebound problem caused by the core wire's own elasticity and ensures the consistency and stability of the shape after separation. Attached Figure Description

Detailed Implementation
[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0031] Reference Figures 1-6A core wire separation mechanism includes a base plate 1, a base 4 on the top of the base plate 1, and a separation component on the top of the base 4.
[0032] The separation assembly includes a clamping component and a separation component. The clamping component includes two second cylinders 13. The output ends of the two second cylinders 13 are respectively connected to a first gripper 11 and a second gripper 12. An adjustable clamping cavity 10 is formed between the first gripper 11 and the second gripper 12 for clamping the core wires respectively.
[0033] The separation component includes a guide rail 9 and two limiting blocks 14 slidably disposed thereon. The limiting blocks 14 are connected to the corresponding second cylinders 13 via connecting plates 17 to realize the relative movement of the first gripper 11 and the second gripper 12.
[0034] First, the operator or an external robotic arm places the combined core wires to be separated into the mechanism through the placement hole 3 on the outer casing 2, aligning the front ends of the two core wires with the clamping cavity 10 between the first gripper 11 and the second gripper 12, respectively. At this point, all components are in their initial reset state. Subsequently, the two second cylinders 13 are activated, and their output ends push the first gripper 11 and the second gripper 12 to move towards each other. The anti-slip texture on the clamping surfaces of the two grippers increases the friction, stably clamping the two core wires in the adjustable clamping cavity 10, ensuring that the core wires will not slip or fall off during the subsequent separation process.
[0035] Once the core wire is securely clamped, the servo motor 5 starts working, and its output end transmits power to the bidirectional threaded rod 6, which is rotatably connected to the two plates 15, via a synchronous belt, driving the bidirectional threaded rod 6 to rotate. Since the outer wall of the bidirectional threaded rod 6 is threadedly connected to the two sliders 16 with opposite thread directions, the two sliders 16 will move relatively away from each other along the threaded rod when the threaded rod rotates. The sliders 16 drive the corresponding second cylinders 13 to move synchronously through the connecting plate 17. At the same time, the limiting block 14 at the bottom of the second cylinder 13 slides along the guide rail 9, providing guidance and stable support for the movement of the grippers. Finally, the first gripper 11 and the second gripper 12, with their respective clamped core wires, separate to both sides, forming the required separation angle.
[0036] Reference Figures 4-6 The top of the base 4 is equipped with a servo motor 5. Two plates 15 are fixedly connected to the top of the base 4. The top of the base 4 is equipped with a bidirectional threaded rod 6. The bidirectional threaded rod 6 is rotatably connected to the two plates 15. The output end of the servo motor 5 is connected to the bidirectional threaded rod 6 via a synchronous belt to drive the bidirectional threaded rod 6 to rotate. Two sliders 16 are threadedly connected to the outer wall of the bidirectional threaded rod 6. The two sliders 16 are fixedly connected to the corresponding connecting plates 17 respectively.
[0037] Since the slider 16 is connected to the second cylinder 13 via the connecting plate 17, and the bottom of the second cylinder 13 is provided with a sliding limit block 14, which is embedded in the guide rail 9 and slides along it, this connection structure indirectly constrains the movement of the slider 16 in the extension direction of the guide rail 9, preventing the slider 16 from rotating circumferentially when it rotates with the bidirectional threaded rod 6, and allowing it to only move linearly along the axial direction of the threaded rod.
[0038] Reference Figures 1-4 The base 4 has a first cylinder 8 at one end, and the output end of the first cylinder 8 is connected to a heating claw 7. The heating claw 7 is located on one side of the first claw 11 and the second claw 12. The clamping surfaces of the first claw 11 and the second claw 12 are provided with anti-slip textures to enhance the clamping force on the core wire.
[0039] After the first gripper 11 and the second gripper 12 pull the core wire to a preset angle (forming a Y-shape or other target shape) under the drive of the separation component, the core wire is then pushed into the heating gripper 7 manually or by an external robotic arm. At this time, the first cylinder 8 drives the heating gripper 7 to fit the separated part of the core wire. The heating gripper 7 is then energized and heats up, heating the separated core wire (especially the insulation layer or surface material) through heat conduction (the heating temperature is generally set between 60-150℃), making it enter a plastic state. The insulation layer or surface material of the core wire completes shape memory under the action of heat, that is, it stabilizes the current separation angle through heat setting. After the shaping is completed, the heating gripper 7 is first de-energized to stop heating, and the residual heat is used to further consolidate the shaping effect. Then, the first cylinder 8 drives the heating gripper 7 to reset and release. At this time, the core wire has formed a stable Y-shaped structure through heat setting and no longer changes its shape due to elastic rebound.
[0040] The heating gripper 7, as a mechanical component integrating clamping and heating functions, falls within the scope of existing technology and will not be elaborated upon here.
[0041] Reference Figures 1-2 The base 4 has a housing 2 on its top. One end of the housing 2 has a placement hole 3 for inserting the core wire. The placement hole 3 is located on one side of the first gripper 11 and the second gripper 12.
[0042] Working principle: The operator or external robotic arm puts the combined core wires to be separated into the mechanism through the placement hole 3 on the outer shell 2, so that the front ends of the two core wires are respectively aligned with the clamping cavity 10 between the first gripper 11 and the second gripper 12. At this time, all components are in the initial reset state.
[0043] The two second cylinders 13 are started, and their output ends push the first gripper 11 and the second gripper 12 to move towards each other. The anti-slip texture on the gripping surface increases the friction, and the two core wires are stably clamped in the gripping cavity 10 to prevent the core wires from sliding or falling off in the subsequent process.
[0044] After the core wire is firmly clamped, the servo motor 5 starts working, and its output end transmits power to the bidirectional threaded rod 6, which is rotatably connected to the two plates 15, through a synchronous belt, driving the bidirectional threaded rod 6 to rotate. Since the outer wall of the bidirectional threaded rod 6 is threadedly connected to the two sliders 16 with opposite thread directions, the two sliders 16 move away from each other along the threaded rod. The sliders 16 drive the corresponding second cylinders 13 to move synchronously through the connecting plate 17. At the same time, the limiting block 14 at the bottom of the second cylinder 13 slides along the guide rail 9, providing guidance and support for the movement of the grippers, so that the first gripper 11 and the second gripper 12, with their respective clamped core wires, separate to both sides to form the required angle.
[0045] Once the core wire is pulled to a preset angle, the first gripper 11 and the second gripper 12 release the core wire. An operator or external robotic arm then pushes the core wire into the heating gripper 7. The first cylinder 8 drives the heating gripper 7 to contact the separated part of the core wire. The heating gripper 7 is energized and heats up, heating the separated core wire through heat conduction. The temperature is controlled between 60-150℃, causing the core wire insulation layer or surface material to enter a malleable state, completing shape memory to stably maintain the separation angle.
[0046] After shaping, the heating gripper 7 is de-energized to stop heating, using residual heat to solidify the shape. Then, the first cylinder 8 drives the heating gripper 7 to reset and release, leaving the core wire with a stable Y-shaped structure. Finally, the operator or an external robotic arm removes the processed core wire, completing a separation operation.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
