Description

Technical Field

[0001] This utility model relates to the field of wire harness assembly and production technology, and in particular to a sleeve device, sleeve equipment and wire harness assembly production line based on reciprocating kneading. Background Technology

[0002] In the wire harness assembly process, after the main body sleeve, core sleeve, and terminal crimping are completed, the insulating tube of the main body of the wire harness needs to be reset and heated to fix the insulating tube in a preset position between the main body and the core segment. Traditional processes rely mainly on manual operation, requiring workers to manually rotate the insulating tube on the main body of the wire harness to move it to the designated position. This manual operation method is not only inefficient, but also prone to inaccurate positioning of the insulating tube due to differences in operator skill levels, affecting the consistency of product quality.

[0003] To address the issues of manual operation, existing technologies employ mechanical clamps to directly hold and move the insulating tube. However, this mechanical operation method has significant drawbacks in practical applications. Since the outer sheath of wire harnesses is typically made of flexible insulating materials such as PVC, rubber, or cross-linked polyethylene, and the insulating tube itself possesses a certain degree of elasticity and resilience in its unheated state, the friction between the insulating tube and the wire harness surface, along with the elasticity of the insulating tube itself, can cause the insulating tube to accumulate on the wire harness surface during mechanical movement. This is especially true when the inner diameter of the insulating tube and the outer diameter of the wire harness are closely matched. Due to the smooth contact surface, low friction, the low bending stiffness of the thin-walled tube when gaps exist, and uneven thrust distribution, the insulating tube is highly prone to wrinkling and accumulation on the wire harness surface. This accumulation not only affects subsequent heating processes but also leads to inaccurate positioning of the insulating tube, severely impacting the quality and production efficiency of the wire harness products. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a sleeve device, sleeve equipment, and wire harness assembly production line based on reciprocating kneading, which has the advantages of improving the positioning accuracy of insulating tubes and the quality of insulating tube sleeves, and helps to improve production efficiency and product quality.

[0005] In a first aspect, the sleeve device based on reciprocating kneading according to an embodiment of the present invention includes:

[0006] Clamping mechanism for securing the wire harness body and / or wire core bundle;

[0007] A kneading mechanism is disposed on one side of the clamping mechanism. The kneading mechanism includes a kneading component and a driving component. The kneading component includes two kneading plates, which are arranged opposite each other to form a kneading cavity. The kneading cavity accommodates the sleeved section of the wire harness. The driving component can drive the two kneading plates to reciprocate linearly relative to each other on a first path. The two kneading plates can repeatedly knead the sleeved section to make the insulating tube and the wire harness body rotate relative to each other.

Two opposing kneading plates in the kneading mechanism form a kneading cavity. A driving component drives the kneading plates to reciprocate linearly along the first path F1, repeatedly kneading the sleeved section.

Furthermore, the pushing mechanism controls the displacement of the clamping mechanism or the kneading mechanism along the second path F2 through the second driving component, achieving precise advancement or retraction of the insulating tube along the axial direction of the wire harness, ensuring accurate positioning of the insulating tube at the preset position between the wire harness body and the core segment. Specifically, the driving component drives the kneading plates to move relative to each other, causing the insulating tube to rotate circumferentially during the kneading process, rather than simply being pushed axially, effectively dispersing local stress. Through the synergistic effect of the pushing mechanism and the kneading mechanism, both axial position adjustment and reduction of static friction resistance between the tube body and the wire harness through rotation are achieved, ultimately preventing the accumulation of insulating tubes.

Specifically, the driving component drives the kneading plates to move relative to each other, causing the insulating tube to rotate circumferentially during the kneading process, rather than simply being pushed axially, effectively dispersing local stress.

[0054] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0055] Reference Figure 1 and Figure 4This utility model provides a sleeve device based on reciprocating kneading, and also provides a sleeve device using the above-mentioned sleeve device.

[0056] like Figure 1 and Figure 4 As shown, the sleeve device mainly consists of a clamping mechanism, a kneading mechanism, and a pushing mechanism. The clamping mechanism is used to fix the main body 1 of the wire harness or the wire core bundle. The kneading mechanism is located on one side of the clamping mechanism, and either the clamping mechanism or the kneading mechanism is connected to the pushing mechanism. Specifically, the kneading mechanism includes a drive assembly and two kneading plates 100, with the two kneading plates 100 forming a sleeved section 2 for accommodating the wire harness. The drive assembly can drive the two kneading plates 100 to reciprocate linearly along the first path F1. It should be noted that the two kneading plates 100 are relatively movable, i.e., as shown... Figures 2 to 3 As shown, when the left washboard 100 moves upward along the first path F1, the right washboard 100 moves downward along the first path F1; conversely, when the left washboard 100 moves downward along the first path F1, the right washboard 100 moves upward along the first path F1. This reciprocating linear motion applies a tangential force to the insulating tube 4, causing the insulating tube 4 and the wire harness body 1 to rotate relative to each other. Furthermore, the pushing mechanism drives the clamping mechanism or the kneading mechanism to move horizontally, causing the insulating tube 4 and the wire harness body 1 to move relative to each other along the axial extension direction of the wire harness body 1.

[0057] It is understandable that the clamping mechanism can use pneumatic clamps or electromagnetic clamps to stably clamp the main body 1 of the wire harness or the core segment 3, ensuring the positional stability of the wire harness during operation.

[0058] That is, when the wire harness segment with the insulating tube 4 is placed in the kneading chamber, the drive assembly drives the two kneading plates 100 to reciprocate in opposite phases along a direction perpendicular to the wire harness axis. The periodic kneading action generates alternating frictional forces on the surface of the insulating tube 4, forming a rotational torque around the wire harness axis. Under the control of the propulsion mechanism, the insulating tube 4 gradually moves to the predetermined position along the axial extension direction of the wire harness body 1 during rotation. The dynamic frictional force generated by the kneading motion is significantly lower than the static frictional force, effectively preventing tube accumulation. Through the synergistic effect of axial propulsion and rotational motion, the insulating tube 4 maintains a uniform stress distribution during movement.

[0059] According to some embodiments of this application, when a propulsion mechanism is provided, the propulsion mechanism can be connected to either the clamping mechanism or the kneading mechanism.

[0060] It is understandable that when the pushing mechanism is connected to the clamping mechanism, the kneading mechanism is fixed and cannot be moved. When the clamping mechanism is used to clamp and fix the wire harness body 1, the kneading mechanism starts and repeatedly kneads the insulating tube 4. At the same time, the pushing mechanism drives the clamping mechanism to move along the second path F2 and gradually move away from the kneading mechanism, so that the insulating tube 4 reaches the predetermined position.

[0061] Alternatively, when the pushing mechanism is connected to the clamping mechanism, the kneading mechanism is fixed and cannot be moved. When the clamping mechanism is used to clamp and fix the core segment 3, the kneading mechanism starts and repeatedly kneads the insulating tube 4. The pushing mechanism then drives the clamping mechanism to move along the second path F2 and gradually approach the kneading mechanism, so that the insulating tube 4 reaches the predetermined position.

[0062] Alternatively, when the pushing mechanism is connected to the kneading mechanism, the clamping mechanism is fixed and cannot be moved. When the kneading mechanism is activated and repeatedly kneads the insulating tube 4, the pushing mechanism drives the kneading mechanism to move along the second path F2 and gradually approach the core segment 3, so that the insulating tube 4 reaches the predetermined position.

[0063] Understandably, this application utilizes a kneading motion to generate rotational movement, bringing the contact surface into a state of dynamic friction to reduce the coefficient of friction. This decomposes the thrust into rotational torque and axial force, resulting in a more uniform stress distribution within the tube. This effectively solves the problem of accumulation during the axial movement of the insulating tube 4, achieving precise relative positioning between the tube and the wire harness. The rotational effect generated by the kneading motion ensures uniform force distribution on the tube, avoiding localized stress concentration. Through the coordinated control of the propulsion mechanism and the kneading mechanism, precise positioning can be achieved without damaging the tube, significantly improving the installation qualification rate of the insulating tube 4, effectively shortening the time required for single-piece operations, and providing reliable technical support for automated production lines.

[0064] Preferably, in this application, the clamping mechanism includes a second base 400, a wire harness clamping assembly 200, and a wire core clamping assembly 300. The wire harness clamping assembly 200 and the wire core clamping assembly 300 are respectively used to clamp and fix the wire harness body 1 and the wire core. Specifically, as shown... Figure 4 As shown, the wire harness clamping assembly 200 and the wire core clamping assembly 300 are both mounted on the second base 400. The wire harness clamping assembly 200 and the wire core clamping assembly 300 are arranged along the second path F2 and are respectively located on both sides of the kneading mechanism. The pushing mechanism is connected to the second base 400.

[0065] Understandably, when the main body 1 of the wire harness is clamped by the clamp of the wire harness clamping assembly 200, the main body 1 of the wire harness forms a rigid connection with the second base 400. At this time, the reciprocating motion applied by the rubbing mechanism only acts on the insulating tube 4 and does not cause overall displacement of the main body 1 of the wire harness. At the same time, when the core bundle is fixed by the clamp of the core bundle clamping assembly 300, the end position of the core bundle is locked. When the pushing mechanism moves the second base 400, the wire harness clamping assembly 200 and the core bundle clamping assembly 300 move synchronously. The relative position between the core bundle and the main body 1 of the wire harness remains unchanged. A horizontal movement path of the insulating tube 4 is formed between the core segment 3 and the main body 1 of the wire harness, effectively solving the problem of sleeve misalignment caused by unstable fixing of the main body 1 of the wire harness or the core bundle. That is, the clamping design of the wire harness clamping assembly 200 eliminates the axial movement of the wire harness body 1 during the rubbing process, allowing the insulating tube 4 to move along a predetermined path; while the independent fixing function of the wire core clamping assembly 300 prevents the wire core bundle from bending during the pushing process, ensuring the alignment accuracy between the insulating tube 4 and the wire core bundle.

[0066] As a further improvement to the solution, the wire harness clamping assembly 200 includes a first clamp 210 and a lifting drive, the output end of which is connected to the first clamp 210; the wire core clamping assembly 300 includes a second clamp 310 and a lifting drive, the output end of which is connected to the second clamp 310.

[0067] Understandably, when the main body 1 of the wire harness needs to be fixed, the lifting drive moves the first clamp 210 vertically to a preset height, and the jaws close to clamp the outer surface of the main body 1 of the wire harness. When the core bundle needs to be fixed, the lifting drive moves the second clamp 310 to the corresponding height, and the clamp closes to fix the end of the core bundle. By independently controlling the lifting action of the two sets of clamps, the clamping positions of the main body 1 of the wire harness and the core bundle can be dynamically adjusted according to the actual working conditions, avoiding axial displacement of the wire harness during the kneading process due to clamping height deviation. During the advancement stage of the insulating tube 4, the lifting drive can compensate for the slight deformation of the wire harness caused by kneading in real time, maintaining a uniform pressure distribution between the clamping surface and the wire harness.

[0068] The advantage is that by actively adjusting the height of the clamp through the lifting drive, the main body 1 of the wire harness and the core segment 3 are always kept at the same height as the wire harness, eliminating the lateral force caused by height deviation and ensuring the reset accuracy of the insulating tube 4.

[0069] In some preferred embodiments of this application, the driving component includes two first driving members 500, the output ends of the two first driving members 500 are respectively connected to two washboards 100, and the first driving members 500 can drive the washboards 100 to reciprocate linearly on a first path.

[0070] It is understandable that the first driving component 500 can be a cylinder, an electric push rod, or a linear motor as the power source for outputting linear reciprocating motion, directly driving the washboard 100 to generate linear displacement. When two first driving components 500 are used, each first driving component 500 independently controls the corresponding washboard 100. By adjusting the motion parameters of the two driving components, such as the stroke length or reciprocating frequency, an asymmetrical motion mode of the two washboards 100 on the first path can be achieved, thereby adapting to the kneading requirements of different wire diameters or insulating tube materials 4.

[0071] In other embodiments of this application, the drive assembly includes a first drive member 500 and a transmission module, the output end of the first drive member 500 is connected to the transmission module, and the two washboards 100 are connected to the transmission module.

[0072] It is understandable that when a single drive component is combined with a transmission module, the output power of the drive component is converted into synchronous reverse motion of the two washboards 100 via the transmission module. For example, the drive assembly can use a servo motor in conjunction with a crank-slider mechanism to make the two washboards 100 reciprocate linearly along the first path F1.

[0073] In both of the above embodiments, this application converts power transmission into linear reciprocating motion of the washboard 100 through the direct or indirect connection between the drive component and the washboard 100, which solves the problem of precise kneading action control that cannot be achieved by traditional manual operation, and avoids uneven force or deformation failure of the wire harness surface insulation tube 4 caused by asynchronous drive.

[0074] According to some embodiments of this application, the kneading assembly further includes a mounting support 600, and the rubbing board 100 is slidably connected to the mounting support 600.

[0075] Understandably, the mounting bracket 600 is fixed to the main body of the equipment as a rigid carrier, and the two washboards 100 are respectively installed on both sides of the bracket through a sliding connection structure. When the drive assembly drives the washboards 100 to reciprocate along the first path, the sliding connection structure restricts the motion trajectory to a single degree of freedom, ensuring that the two washboards 100 always maintain a parallel alignment. During this process, the rigidity of the mounting bracket 600 suppresses the swaying of the washboards 100 caused by mechanical vibration, and the guiding effect of the sliding connection structure eliminates the trajectory deviation caused by assembly gaps. This ensures that the kneading cavity always makes uniform contact with the clamping surface of the sleeved section 2, so that the relative rotational force between the insulating tube 4 and the wire harness body 1 is evenly distributed axially, avoiding tube accumulation caused by local stress concentration.

[0076] Beneficially, this application constructs a rigid motion system with trajectory constraints through the combination of the mounting support 600 and the sliding connection. This system accurately converts the output force of the drive component into the linear reciprocating motion of the washboard 100, solving the problem of uneven kneading force transmission caused by mechanical backlash and vibration. It effectively eliminates deviations in the movement trajectory of the washboard 100, ensuring that the kneading force is uniformly transmitted axially to the surface of the insulating tube 4, and avoiding tube accumulation due to insufficient local friction. Simultaneously, the cooperation between the rigid mounting support 600 and the guide structure reduces vibration noise during equipment operation and improves the repeatability and positioning accuracy of the kneading action, providing a fundamental guarantee for the stable movement and precise positioning of the insulating tube 4.

[0077] As a further improvement to the solution, a first guide structure is provided between the mounting support 600 and the washboard 100. The first guide structure includes a first guide rail and a first slide. The mounting support 600 is provided with the first guide rail, and the washboard 100 is provided with the first slide. The first guide rail and the first slide are slidably connected.

[0078] It is understandable that the first guide rail refers to a rigid track structure extending along the first path, which can be implemented using a linear guide rail or a dovetail groove structure, and is used to limit the movement trajectory of the sliding component. The first slide block refers to a sliding component that matches the first guide rail, which can be implemented using a slider or a sliding sleeve structure, and forms a low-friction pair with the guide rail through rolling elements or sliding surfaces.

[0079] Specifically, the rigid fit between the first guide rail and the first slide constrains the reciprocating motion trajectory of the washboard 100 to a strictly straight path. When the drive assembly moves the washboard 100, the first slide slides along the extension direction of the first guide rail, eliminating motion deviation caused by transmission clearance or load changes. This application achieves high-precision linear guidance within a limited space through the cooperation of the first guide rail and the first slide, while reducing the dependence on the transmission accuracy of the drive assembly. This ensures that the washboard 100 maintains a straight trajectory during high-speed reciprocating motion, avoiding misalignment between the insulating tube 4 and the wire harness body 1 due to motion deviation, thereby improving the reliability of the insulating tube 4 position adjustment and ensuring the assembly quality of the wire harness product.

[0080] As a further improvement to the solution, this application also includes an adjustment mechanism for adjusting the size of the kneading cavity. Specifically, the adjustment mechanism includes a first base 700 and a third drive member 800. The mounting support 600 is slidably connected to the first base 700, and the third drive member 800 is fixed to the first base 700. The output end of the third drive member 800 is connected to one end of the mounting support 600, and the third drive member 800 can drive the washboard 100 to move away from or closer to another washboard 100.

[0081] Understandably, after the third drive unit 800 is activated, its output end pushes the mounting bracket 600 to slide along the first base 700, causing the washboard 100 fixed to the mounting bracket 600 to move synchronously. When the distance between the two washboards 100 needs to be increased, the third drive unit 800 drives the mounting bracket 600 to move away from the other washboard 100; when the distance needs to be decreased, the mounting bracket 600 moves in the opposite direction. During this process, the sliding connection structure constrains the movement trajectory of the mounting bracket 600, preventing the washboard 100 from shifting or tilting. Thus, the width of the kneading cavity can be dynamically adjusted according to the outer diameter of the wire harness sleeved section 2 or the size of the insulating tube 4, ensuring effective contact pressure of the kneading action, while avoiding damage to the wire harness surface or insufficient kneading force due to mismatch in cavity size.

[0082] Beneficially, this application achieves active adjustment of the spacing between the washboards 100 through the combination of the third driving component 800 and the sliding connection. This allows the kneading cavity to adapt to wire harnesses or insulating tubes 4 of different diameters, eliminating the kneading failure problem caused by size differences. It also solves the problem of insufficient adaptability of the kneading mechanism to wire harnesses and insulating tubes 4 of different sizes, avoiding the defect of the kneading cavity being unable to match the size of the sleeved section 2 due to the fixed spacing of the washboards 100. By dynamically adjusting the width of the kneading cavity, effective friction is ensured between the insulating tube 4 and the wire harness, preventing the insulating tube 4 from accumulating on the surface of the wire harness, thereby improving the reset accuracy of the insulating tube 4 and the efficiency of subsequent heat treatment.

[0083] As a further improvement to the solution, the adjustment mechanism also includes a second guide structure, which includes a second guide rail and a second slide. The first base 700 is provided with the second guide rail, and the mounting base is provided with the second slide.

[0084] Understandably, when the third driving component 800 pushes the mounting bracket 600 to move, the sliding fit between the second guide rail and the second slide restricts the lateral displacement of the mounting bracket 600, ensuring that the two washboards 100 maintain a parallel movement trajectory during the spacing adjustment process. The rigid contact surface between the guide rail and the slide provides axial support, preventing the washboards 100 from tilting due to unilateral force. This application achieves bidirectional constraint within a limited space through the combination of the second guide rail and the second slide, eliminating motion deviation caused by mechanical clearance, ensuring that the plane of the washboards 100 is always perpendicular to the wire harness axis during the kneading cavity size adjustment process, solving the problem of kneading action deviation caused by mechanical instability during the kneading cavity size adjustment process, keeping the relative rotation direction of the insulating tube 4 and the wire harness stable, avoiding kneading failure caused by mechanism shaking, and ensuring that the insulating tube 4 is evenly stressed and accurately reset to the preset position.

[0085] This application also provides a casing device that utilizes the aforementioned casing assembly. Specifically, as shown... Figure 4As shown, the second base 400 in the bushing device is the fixed base in the bushing equipment. The wire harness clamping assembly 200 and the wire core clamping assembly 300 are both installed on the second base 400. The second drive component of the push mechanism can be integrated on the second base 400, while the first base 700 is slidably connected to the second base 400. The second drive component of the push mechanism is connected to the first base 700 to drive the first base 700 to move horizontally and reciprocally in a linear motion.

[0086] Furthermore, referring to Figure 4 The first base 700 is provided with two kneading mechanisms. Correspondingly, the wire harness clamping assembly 200 and the wire core clamping assembly 300 are each provided with two sets to match the two kneading mechanisms respectively. This enables the simultaneous kneading of two sleeved sections 2 of the same wire harness, or the simultaneous kneading of sleeved sections 2 on two wire harnesses of the same specification, which can effectively improve production efficiency.

[0087] As a further improvement to the solution, the washboard can have a built-in heating component, such as a resistance wire or heating film, embedded inside the washboard. During the rubbing process, the surface of the insulating tube is directly heated, promoting its thermal contraction.

[0088] Alternatively, in some other embodiments of this application, the washboard itself is a heating plate.

[0089] Furthermore, a temperature sensor can be installed to monitor the temperature of the washboard in real time to prevent it from overheating.

[0090] This application shortens the shrinkage time of the insulating tube by simultaneously heating, kneading, and linearly moving the insulating tube, avoids overheating of the wire harness by local heating, and improves the efficiency of heat shrinking and fixing of the sleeve.

[0091] Optionally, the surface of the washboard can be provided with anti-slip texture to increase friction with the insulating tube and prevent slippage and failure during rubbing.

[0092] This application also provides a wire harness assembly production line that uses the above-mentioned sleeve device, or a wire harness assembly production line that uses the above-mentioned sleeve equipment, which realizes uniform deformation control of the insulating tube 4 during the pushing process and solves the problem of tube accumulation caused by single-point force application.
