Description

Technical Field

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

[0002] In the wire harness manufacturing process, terminal crimping at the wire core ends is a critical step. Traditional processes suffer from several technical bottlenecks: First, after the insulation layer is removed, the metal wires are in a loose state, causing some wires to fail to make full contact with the terminals during crimping, severely affecting connection reliability and conductivity. Currently, the industry commonly uses manual twisting, where workers manually twist the exposed wires into bundles before transporting them to the crimping station. This method poses significant safety hazards, as the metal wire strands can easily injure the operator's hands. Furthermore, manual operation makes it difficult to ensure consistent twisting force, directly impacting the quality stability of the wire harness products.

[0003] Existing technologies also suffer from fragmented processes. Stripping, twisting, and crimping require different equipment, and the alignment and insertion of wire cores and terminals rely entirely on manual operation. This fragmented processing model is not only inefficient and unable to meet the high-speed operation requirements of modern production lines, but also cannot achieve mass automated production. Especially in multi-core wire harness processing scenarios, traditional processes require repeated handling of wires, which increases labor intensity and easily damages the wires.

If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0026] 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.

[0027] Reference Figures 1 to 3 This utility model provides a terminal crimping device, wherein the terminal crimping device uses the linear feeding terminal crimping device provided in this application.

[0028] Specifically, such as Figure 1As shown, the terminal crimping device includes a wire core clamping mechanism, a terminal crimping mechanism, and a moving mechanism. The wire core clamping mechanism includes a first clamping module 100 and a stripping and twisting module 200; the former fixes the wire core body, and the latter performs insulation stripping and wire twisting. The terminal crimping mechanism has a crimping module 300 to fix the terminal. The moving mechanism is connected to at least one processing mechanism and achieves automatic insertion of the wire core and terminal through relative displacement.

[0029] Understandably, after the wire core clamping mechanism clamps the wire, the stripping and twisting module 200 strips the insulation layer from the wire core and applies rotational torque to the exposed conductor. The processed wire core is then moved to the crimping station 2 via a moving mechanism, where the crimping module 300 simultaneously adjusts its spatial orientation to ensure coaxial alignment between the crimped section of the wire core and the terminal. The moving mechanism automatically calculates the displacement based on the wire core length, eliminating the impact of processing errors on crimping accuracy. The entire process is controlled by a program, eliminating the need for manual intervention.

[0030] Beneficially, this application achieves continuous processing through integrated design, automating the stripping, twisting, and crimping processes and eliminating safety hazards associated with manual operation. Furthermore, precise alignment of the wire core and terminals improves the crimping pass rate and effectively increases processing efficiency. Additionally, the integrated equipment layout reduces the workshop floor space required.

[0031] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the moving mechanism includes a first moving module 400, which includes a first translation component 410 and a lifting component 420. The lifting component 420 is mounted on the first translation component 410. The first clamping module 100 is connected to the lifting component 420. The first translation component 410 can drive the first clamping module 100 away from or closer to the terminal crimping mechanism.

[0032] It is understood that the first translation component 410 refers to the drive component that adjusts the position in the horizontal direction, which can be implemented using a lead screw mechanism or a linear motor, and is used to control the horizontal distance between the first clamping module 100 and the terminal crimping mechanism. The lifting component 420 refers to the drive component that adjusts the height in the vertical direction, which can be implemented using a cylinder or a servo electric cylinder, and is used to adjust the height of the first clamping module 100 to meet the alignment requirements of the terminal crimping mechanism.

[0033] Specifically, after the first clamping module 100 fixes the wire core, the first translation component 410 drives it to move horizontally to a target position close to the terminal crimping mechanism. Simultaneously, the lifting component 420 adjusts the height of the wire core end to align it coaxially with the crimping hole of the terminal crimping mechanism. Then, the first translation component 410 drives the first clamping module 100 to continue moving a preset distance toward the terminal crimping mechanism so that the section of the wire core to be crimped is inserted into the terminal. After insertion, the terminal crimping mechanism is activated to complete the terminal crimping process. Finally, the first translation component 410 restarts, resetting the first clamping module 100. The wire core that has completed terminal crimping can be transferred to the next process via a transfer mechanism, or the first clamping module 100 releases the wire core, and the wire core that has completed terminal crimping is transported to the finished product collection mechanism.

[0034] In other embodiments of this application, the moving mechanism includes a second translation component (not shown in the figure), and the terminal crimping mechanism is connected to the second translation component. The second translation component can drive the terminal crimping mechanism away from or towards the first clamping module 100.

[0035] It is understood that the second translation component refers to the driving component that adjusts the position in the horizontal direction. Specifically, it can be implemented by a lead screw mechanism or a linear motor, and is used to control the horizontal distance between the first clamping module 100 and the terminal crimping mechanism.

[0036] That is, after the first clamping module 100 fixes the wire core, the second translation component drives the terminal crimping mechanism to move horizontally to a target position close to the first clamping module 100, so that the first clamping module 100 is coaxially aligned with the crimping hole of the terminal crimping mechanism. Subsequently, the second translation component drives the terminal crimping mechanism to continue moving towards the first clamping module 100 a preset distance so that the section of the wire core to be crimped is inserted into the terminal. After insertion, the terminal crimping mechanism starts to complete the terminal crimping process. Finally, the second translation component restarts, driving the terminal crimping mechanism to reset. The wire core that has completed terminal crimping can be transferred to the next process through the transfer mechanism, or the first clamping module 100 releases the wire core, and the wire core that has completed terminal crimping is transported to the finished product collection mechanism.

[0037] Furthermore, the terminal crimping mechanism may also be connected to a lifting component for adjusting the height of the terminal crimping mechanism in the vertical direction to meet the alignment requirements of the first clamping module 100 and the terminal crimping mechanism.

[0038] In other embodiments of this application, the moving mechanism includes a first moving module 400 and a second moving module. For example, Figure 1As shown, the first moving module 400 includes a first translation component 410 and a lifting component 420. The lifting component 420 is mounted on the first translation component 410. The first clamping module 100 is connected to the lifting component 420. The first translation component 410 can move the first clamping module 100 away from or towards the terminal crimping mechanism. The second moving module includes a second translation component. The terminal crimping mechanism is connected to the second translation component. The second translation component can move the terminal crimping mechanism away from or towards the first clamping module 100.

[0039] It is understandable that the second translation component refers to a horizontal drive component independent of the first moving module 400. Specifically, it can be implemented using a synchronous belt drive or a ball screw mechanism, and is used to directly adjust the position of the terminal crimping mechanism to actively move closer to or away from the wire core clamping mechanism.

[0040] That is, after the first clamping module 100 fixes the wire core, the first translation component 410 drives it to move horizontally to the target position close to the terminal crimping mechanism. At the same time, the lifting component 420 adjusts the height of the wire core end to align it coaxially with the crimping hole of the terminal crimping mechanism. Subsequently, the first translation component 410 drives the first clamping module 100 to continue moving towards the terminal crimping mechanism a preset distance. The second translation component can be activated simultaneously to move the terminal crimping mechanism towards the first clamping module 100 a preset distance so that the section of the wire core to be crimped can be inserted into the terminal. After insertion, the terminal crimping mechanism is activated to complete the terminal crimping process. Finally, the first translation component 410 and the second translation component restart, respectively driving the first clamping module 100 and the terminal crimping mechanism to reset. The wire core that has completed terminal crimping can be transferred to the next process through the transfer mechanism, or the first clamping module 100 releases the wire core, and the wire core that has completed terminal crimping is transported to the finished product collection mechanism.

[0041] Beneficially, this application achieves fully automatic position adjustment of the wire core clamping mechanism and the terminal crimping mechanism through independent or combined driving of the first moving module 400 and the second moving module, avoiding errors and safety risks caused by manual intervention, solving the problems of low efficiency and safety hazards caused by manual handling during the insertion of wire cores and terminals, and ensuring the axial alignment accuracy between the wire core end and the terminal through mechanized translation and lifting coordinated control, improving the consistency of crimping quality, and meeting the needs of automated production lines for continuous operation.

[0042] According to some embodiments of this application, such as Figure 1 and Figure 6 As shown, the terminal crimping mechanism includes a crimping module 300 and a flipping module 500. The crimping module 300 is connected to the flipping module 500. The flipping module 500 can drive the crimping module 300 to switch positions between the receiving station 1 and the crimping station 2 so that the terminal and the wire core are coaxial.

[0043] In this application, the receiving station 1 refers to the fixed area where the terminal is positioned by the conveying device, while the crimping station 2 refers to the working position where the terminal and the wire core axis coincide.

[0044] It is understandable that the flipping module 500 refers to the mechanical structure that drives the crimping module 300 to perform spatial position transformation. Specifically, it can be implemented by a swing arm mechanism driven by a rotary cylinder or servo motor. Its function is to transfer the crimping module 300 from the position of the receiving terminal to the crimping position aligned with the wire core axis through a rigid transmission path.

[0045] Specifically, when the terminal is conveyed to receiving station 1, the flipping module 500 drives the crimping module 300 to rotate around a fixed axis, for example, by using a swing arm mechanism to change the crimping module 300 from a horizontal receiving posture to a vertical crimping posture. During this process, the clamping unit of the crimping module 300 keeps the terminal fixed to prevent positional displacement. When the crimping module 300 reaches crimping station 2, its axis coincides with the axis of the wire core held by the wire core clamping mechanism. When the moving mechanism moves the wire core, allowing it to be coaxially inserted with the terminal, the pressing unit of the crimping module 300 performs the crimping action. Through the rigid transmission of the flipping module 500, the transfer path of the terminal from receiving station 1 to crimping station 2 is precisely defined, eliminating axis deviation caused by manual handling.

[0046] Beneficially, this application achieves station switching through the single-degree-of-freedom movement of the flip module 500, which simplifies the mechanical structure and ensures axial consistency during terminal transfer through a rigid transmission path. This avoids the cumulative errors of multi-axis positioning systems, achieves automatic axial positioning of terminals and wire cores, eliminates the need for manual station adjustment, and improves the positioning accuracy of crimping operations to the inherent accuracy level of the mechanical system. Simultaneously, the station switching process is entirely automated by the mechanical structure, avoiding the risk of pinching injuries to operators from contact with moving parts, and enabling seamless integration of the terminal crimping cycle with the wire core processing steps.

[0047] Specifically, in some embodiments of this application, such as Figure 4 As shown, the crimping module 300 includes a crimping seat 310 and a crimping block 320. A plurality of crimping blocks 320 are circumferentially spaced to form a crimping hole. At least one crimping block 320 is movably connected to the crimping seat 310 so that the movable crimping block 320 has a first state close to the crimping hole and a second state away from the crimping hole.

[0048] In this application, the first state refers to the crimping block 320 being in the closed position with the minimum diameter of the crimping hole. This can be achieved by driving the crimping block 320 inward using a hydraulic cylinder or a servo motor, ensuring tight contact between the terminal and the metal wire during the crimping process. The second state refers to the crimping block 320 being in the open position with the maximum diameter of the crimping hole, providing operating space when loading and unloading terminals.

[0049] It is understood that the crimping base 310 refers to the base structure used to support and fix the crimping blocks 320. Specifically, it can be implemented using a metal base with guide grooves or slide rails. Its function is to provide a stable mounting foundation for the crimping blocks 320, ensuring that the movement trajectory of each crimping block 320 is controllable during the crimping process. The crimping block 320 refers to the component that directly participates in the crimping of the terminal and the metal wire. Specifically, it can be implemented using a split wedge block structure. Its function is to form variable-diameter crimping holes through circumferential arrangement, thereby adapting to different wire diameters and terminal sizes. The movable connection refers to the movable connection between the crimping blocks 320 and the crimping base 310. Specifically, it can be implemented using a sliding pair or hinge mechanism. Its function is to control the radial displacement of the crimping blocks 320 through a driving component, realizing the expansion or contraction of the crimping holes.

[0050] Specifically, after the crimping module 300 receives the terminal, the terminal is clamped in the crimping hole. The flipping module 500 is activated, switching the terminal from receiving station 1 to crimping station 2. After the terminal and wire core are coaxially aligned, the moving mechanism drives the wire core to move, so that the wire core and the terminal are coaxially inserted. After the metal wire at the end of the wire core is inserted into the terminal, the movable crimping block 320 moves towards the center of the crimping hole to the first state. Multiple crimping blocks 320 together form a closed crimping hole that matches the outer diameter of the terminal, and radial pressure is applied to ensure full contact between the terminal and the metal wire. After the crimping process is completed, the movable crimping block 320 moves outward to the second state, and the diameter of the crimping hole expands to release the crimped wire bundle or insert a new terminal.

[0051] This application does not specifically limit the number of movable crimp blocks 320. Optionally, the independent movement of one or more crimp blocks 320 allows for local fine-tuning of the crimp hole, for example, adjusting only the crimp block 320 at the corresponding position when crimping asymmetrical terminals.

[0052] Alternatively, in some other embodiments, the symmetrical movement of the group of crimping blocks 320 can maintain a uniform distribution of crimping force, preventing the metal wire from shifting due to unilateral force during the crimping process.

[0053] Beneficially, this application achieves dynamic adjustment of the crimping hole size through the movable crimping block 320, allowing for the processing of objects of different sizes without changing the mold. In the prior art, fixed crimping holes easily lead to insufficient contact between the metal wire and the terminal. This application, however, forcibly eliminates the loose state of the wire through the closing action of the crimping block 320, ensuring that all metal wires are tightly fitted to the inner wall of the terminal after crimping. This solves the problem that the crimping module 300 cannot adapt to terminals and wire cores of different sizes. Dynamic adjustment of the crimping hole size achieves multi-specification compatibility and avoids poor contact caused by mismatched hole diameters. Furthermore, the symmetrical movement of the grouped crimping blocks 320 further prevents wire misalignment during crimping, improving the consistency of crimping quality.

[0054] This application also provides a layout of the stripping module 200 and the terminal crimping mechanism.

[0055] In some embodiments of this application, the stripping and twisting module 200 and the terminal crimping mechanism are arranged side by side in a direction perpendicular to the wire core axis. The moving module also includes a third translation component. The first translation component 410 is connected to the third translation component. The third translation component can drive the first clamping module 100 to switch positions between the stripping and twisting module 200 and the terminal crimping mechanism.

[0056] It is understandable that the third translation component refers to the linear motion mechanism that drives the first clamping module 100 to move laterally. Specifically, it can be implemented by a slide rail and lead screw mechanism or a cylinder drive, and is used to enable the first clamping module 100 to switch laterally between the stripping and twisting station 4 and the pressing station 2.

[0057] That is, in the layout perpendicular to the wire core axis, the stripping and twisting module 200 and the terminal crimping mechanism are arranged horizontally, wherein the third translation component and the first translation component 410 form a compound motion mechanism. After the wire core is stripped and twisted, the third translation component drives the first clamping module 100 to move laterally to the crimping station 2, and then the first translation component 410 drives the first clamping module 100 to move longitudinally, so that the terminal and the wire core are inserted and crimped.

[0058] In some other embodiments, such as Figure 1 and Figure 6 As shown, the stripping and twisting module 200 and the terminal crimping mechanism are arranged side by side along the extension direction of the wire core axis. The stripping and twisting module 200 is located below the receiving station 1. The first translation component 410 can drive the first clamping module 100 to adjust its position between the stripping and twisting module 200 and the terminal crimping mechanism.

[0059] It is understandable that, such as Figure 6 As shown, the layout below the receiving station 1 means that the stripping and twisting module 200 is located in the flipping area of ​​the terminal crimping mechanism, and the process connection is achieved through vertical spatial superposition.

[0060] That is, in the layout extending along the wire core axis, the stripping and twisting module 200 is directly set below the receiving station 1. The first translation component 410 drives the first clamping module 100 to move linearly along the axial direction of the wire core for a first displacement, so that the wire core reaches the stripping and twisting station 4. After the stripping and twisting module 200 completes the insulation layer removal and metal wire twisting process at the end of the wire core, the first translation component 410 drives the first clamping module 100 to move linearly in the opposite direction along the axial direction of the wire core for a second displacement, so that the first clamping module 100 retracts to the crimping station 2. Subsequently, the flipping module 500 is activated, and the flipping module 500 drives the crimping module 300 to rotate around the fixed axis, so that the crimping module 300 that has received the terminal switches to the crimping station 2. When the crimping module 300 reaches the crimping station 2, its axis coincides with the axis of the wire core held by the wire core clamping mechanism. When the moving mechanism drives the wire core to move, so that the wire core and the terminal are coaxially inserted, the punching unit of the crimping module 300 performs the crimping action.

[0061] Both layout methods provided in this application achieve continuous automated processing of the peeling, twisting and pressing processes through the coordinated cooperation of spatial arrangement and translation components.

[0062] Beneficially, this application integrates the wire stripping and twisting module 200 with the terminal crimping mechanism, and utilizes the automated drive of the translation component to directly transfer the wire core to the crimping station 2 via mechanical movement after stripping and twisting, eliminating the manual handling step. The existing technology's problems of large space occupation and redundant operation lines caused by separating the stripping and twisting equipment are solved in this application through a compact vertical or axial layout, achieving automated connection between the wire stripping and twisting processes and the terminal crimping process, avoiding efficiency losses and safety risks caused by manual handling of the wire core. Through precise control of the translation component, the wire core can be directly transferred to the crimping station 2 after stripping and twisting, improving processing speed while ensuring wire core positioning accuracy. The two layout methods can be flexibly selected according to the production line space conditions, optimizing the equipment structure compactness while ensuring process continuity.

[0063] According to some embodiments of this application, such as Figure 5 As shown, the stripping and twisting module 200 includes a cutting mechanism 210 and a stripping and twisting mechanism 220. The cutting mechanism 210 and the stripping and twisting mechanism 220 are arranged side by side along a direction perpendicular to the core axis. The third translation component can drive the first clamping module 100 to switch positions between the cutting mechanism 210 and the stripping and twisting mechanism 220.

[0064] In this application, the cutting mechanism 210 refers to the execution unit used to remove the insulation layer at the end of the wire core. Specifically, it can be implemented using a rotary blade or a laser cutting device, with precise control of the cutting depth to avoid damaging the internal metal wire. The stripping and twisting mechanism 220 refers to the execution unit used to clamp and twist the exposed metal wire. Specifically, it can be implemented using a pneumatic gripper in conjunction with a rotary drive device, with the wire forming a tightly bundled structure by setting the number of twists. The third translation component refers to the transmission unit that drives the first clamping module 100 to move laterally. Specifically, it can be a combination structure of a linear guide rail and a servo motor, with precise positioning for workstation switching achieved through a position feedback system.

[0065] It is understood that the cutting mechanism 210 and the stripping and twisting mechanism 220 are arranged side by side in a straight line in the horizontal direction. When the third translation component moves the first clamping module 100 holding the wire core laterally to the cutting station 3, and the insulation layer is removed, it moves laterally again to the stripping and twisting station 4 to twist the wire. Alternatively, the third translation component moves the first clamping module 100 holding the wire core laterally to the cutting station 3, and after the cutting mechanism 210 cuts the insulation layer of the wire core to form the stripping starting point, the third translation component is activated again, moving the first clamping module 100 laterally to the stripping and twisting station 4 to twist the wire and remove the insulation layer.

[0066] Specifically, such as Figure 5 As shown, the stripping and twisting mechanism 220 includes a second clamping module 221, a second driving member 222, and a fourth translation component 223. The second driving member 222 is connected to the fourth translation component 223, and the second clamping module 221 is connected to the second driving member 222. The second clamping module 221 is used to clamp the insulation layer to be stripped. The second driving member 222 can drive the second clamping module 221 to rotate and twist the metal wire into strands. The fourth translation component 223 can drive the second clamping component to move linearly so that the insulation layer is separated from the wire core.

[0067] Understandably, the second clamping module 221 refers to a mechanical clamping device for fixing the insulation layer, specifically implemented using pneumatic or electric grippers. Its clamping surface can be provided with anti-slip textures to enhance friction, ensuring stable clamping of the insulation layer during the peeling process. The second drive component 222 refers to an actuator that provides rotational power, specifically implemented using a servo motor or stepper motor, connected to the second clamping assembly via a coupling, used to precisely control the torsion angle and rotational speed of the metal wire. The fourth translation component 223 refers to a transmission mechanism that achieves linear displacement, specifically implemented using a ball screw module or linear motor module. Its direction of movement is parallel to the wire core axis, used to pull the insulation layer axially along the wire core after torsion.

[0068] That is, after the cutting mechanism 210 cuts the insulation layer of the wire core to form the peeling starting point, the second clamping module 221 closes and clamps the cut insulation layer segment. The second driving member 222 drives the second clamping module 221 to rotate the insulation layer and the internal metal wire synchronously, so that the metal wire forms a tight bundle structure during the torsional deformation process. After the rotation action is completed, the fourth translation component 223 drives the second clamping module 221 to move along the axial direction of the wire core, and uses mechanical traction force to completely peel the cut insulation layer from the wire core body. Alternatively, the fourth translation component 223 and the second driving member 222 start synchronously. While the second driving member 222 drives the second clamping module 221 to rotate, the fourth translation component 223 simultaneously drives the second clamping module 221 and the second driving member 222 to move along the axial direction of the wire core, so that the metal wire forms a tight bundle structure during the torsional deformation process, while pulling the insulation layer along the axial direction of the wire core.

[0069] Alternatively, in other embodiments of this application, the cutting mechanism 210 and the stripping and twisting mechanism 220 are arranged in the horizontal direction along the axial extension direction of the wire core. When the cutting mechanism 210 cuts the insulation layer of the wire core to form a stripping starting point, the cutting mechanism 210 can be withdrawn from the cutting station 3 by the moving device. The first translation component 410 drives the first clamping module 100 to move toward the stripping and twisting mechanism 220 located behind the cutting mechanism 210, so that the wire core reaches the stripping and twisting station 4. The second clamping module 221 closes and clamps the cut insulation layer segment. After the rotation action is completed, the fourth translation component 223 drives the second clamping module 221 to move along the axial direction of the wire core. The mechanical traction force is used to completely peel the cut insulation layer from the wire core body. Alternatively, the fourth translation component 223 and the second driving component 222 start synchronously. While the second driving component 222 drives the second clamping module 221 to rotate, the fourth translation component 223 simultaneously drives the second clamping module 221 and the second driving component 222 to move along the axial direction of the wire core, so that the metal wire forms a tight bundle structure during the torsional deformation process, while pulling the insulation layer along the axial direction of the wire core. After the insulation layer is removed, the fourth translation component 223 drives the stripping and twisting mechanism 220 to reset, while the first translation component 410 moves backward to bring the wire core to the crimping station 2 for terminal crimping.

[0070] Both layout methods described above achieve process switching through motion control of translation components, enabling wire stripping and twisting operations to be completed in a continuous automated process, avoiding intermediate handling steps. Compared to traditional equipment that requires manual transfer of wire cores from the stripping machine to the twisting machine, resulting in efficiency loss and safety hazards, this application, through modular integration of cutting and stripping / twisting functions, eliminates manual intervention and allows for flexible selection of the optimal layout scheme based on production line space conditions. This solves the problem of low processing efficiency caused by the separation of cutting and twisting processes, achieving seamless connection between wire stripping and twisting. The automated workstation switching mechanism avoids manual handling operations, improving processing safety. The two selectable layout methods can adapt to the space constraints of different production lines, enhancing the flexibility of equipment deployment. The modular design simplifies the equipment structure, reduces maintenance complexity, and ensures consistent processing accuracy.

[0071] Furthermore, this application eliminates the risk of wire punctures by replacing manual gripping with mechanical clamping; it uses a servo motor to control the torsion angle, ensuring uniform twisting force of the wire harness; and the linear module achieves precise displacement control, ensuring standardized insulation stripping action. This enables automated, continuous operation of twisting and bundling metal wires and stripping insulation, solving the problems of low efficiency, poor safety, and inconsistent quality associated with manual operation. The combination of mechanical clamping and servo drive ensures precise control of the wire harness torsion angle, and the synchronous displacement of the linear module ensures reliable insulation stripping, thereby improving wire harness processing quality and production efficiency.

[0072] According to some embodiments of this application, such as Figure 3 As shown, the first clamping module 100 includes a mounting base 110, a first clamping member 120, and a first driving member 130. The two first clamping members 120 are arranged opposite each other to form a first clamping cavity. The first clamping member 120 is slidably connected to the mounting base 110. The output end of the first driving member 130 is connected to the first clamping member 120. The first driving member 130 can drive one first clamping member 120 away from or closer to the other first clamping member 120.

[0073] It is understandable that the first driving element 130 refers to the actuator that provides clamping power, which can be an electric push rod or a cylinder, driving the clamping elements to produce displacement through linear or rotary output. The first clamping cavity refers to the variable space formed by the two clamping elements relative to each other, and the clamping distance or angle can be adjusted by the driving element to form a clamping area that adapts to different wire diameters.

[0074] That is, the wire core is clamped in a clamping cavity formed by two first clamping members 120. When the first driving member 130 is activated, one of the first clamping members 120 moves linearly along the guide rail of the mounting base 110, changing the lateral spacing of the first clamping cavities. Alternatively, in some other embodiments, both first clamping members 120 are connected to the first driving member 130, and the first driving member 130 drives the corresponding first clamping member 120 to move linearly along the guide rail of the mounting base 110, thereby changing the lateral spacing of the first clamping cavities.

[0075] Alternatively, in some other embodiments of this application, the first clamping module 100 includes a mounting base 110, a first clamping member 120, and a first driving member 130. The two first clamping members 120 are arranged opposite each other to form a first clamping cavity. The first clamping member 120 is hinged to the mounting base 110. The output end of the first driving member 130 is connected to the first clamping member 120. The first driving member 130 can drive the first clamping member 120 to rotate so as to adjust the opening and closing range of the first clamping cavity.

[0076] That is, the wire core is clamped in the clamping cavity formed by the two first clamping members 120. When the first driving member 130 is activated, the first clamping member 120 rotates around the hinge point of the mounting base 110, changing the opening angle of the first clamping cavity.

[0077] In both embodiments of the first clamping module 100 provided in this application, the clamping force is automatically adjusted through mechanical transmission. The wire core is evenly wrapped in the clamping cavity to avoid clamping deviation caused by manual operation. When processing wire cores of different diameters, the drive unit adjusts the stroke according to the preset program so that the size of the clamping cavity accurately matches the outer diameter of the wire core. Through the adjustable clamping cavity structure, the same clamping module is compatible with multiple specifications of wire cores.

[0078] like Figure 1 As shown, the terminal crimping device provided in this application has two terminal crimping devices. Specifically, the two terminal crimping devices are arranged side by side.

[0079] It is understandable that the two crimping devices are arranged in parallel along the horizontal direction. Specifically, this can be achieved by using a shared equipment frame or an independent mounting base, thereby optimizing the spatial layout to enable simultaneous processing of the two lines.

[0080] Specifically, the two crimping devices achieve synchronized operation through a shared control module. When the moving mechanism drives the wire core clamping mechanism and the terminal crimping mechanism to move relative to each other, the two devices can simultaneously complete the terminal crimping process of two wire cores with the same processing requirements, or simultaneously complete the terminal crimping process of the two ends of a single wire core. This solves the problem of low efficiency in single-wire processing, meets the needs of batch automated production, eliminates the need for manual intervention in wire core transfer during processing, eliminates operational safety hazards, and ensures the consistency of wire harness quality.

[0081] Furthermore, such as Figure 1 As shown, the moving mechanism is also provided with a mounting bracket 430, and two first clamping modules 100 are mounted on the mounting bracket 430. The mounting bracket 430 is connected to the lifting assembly 420.

[0082] Understandably, the first translation component 410 drives the mounting bracket 430 horizontally via a linear drive, causing the two first clamping modules 100 to synchronously move closer to or further away from the terminal crimping mechanism, ensuring consistent displacement of the clamping modules during dual-wire processing. The rigid connection structure of the mounting bracket 430 forms a single unit with the two clamping modules, preventing relative displacement errors during translation. The lifting component 420 drives the mounting bracket 430 vertically, enabling the two clamping modules to synchronously adjust their height, ensuring height alignment of the dual wires at crimping station 2 and cutting station 33. By integrating translation and lifting functions into the first moving module 400, only a single drive source is needed to achieve synchronous control of the two clamping modules, reducing the number of independent drive units and simplifying the equipment structure.

[0083] Beneficially, this application eliminates the cumulative errors caused by the independent movement of the two modules through the rigid connection and unified drive of the mounting bracket 430, while reducing the number of drive components, optimizing the equipment layout space, and realizing synchronous displacement control of the clamping modules during dual-wire processing. This solves the problem of low positioning accuracy caused by independent drive, and at the same time, the structural integration reduces redundant components in the equipment, improving the efficiency of automated processing. The rigid connection design of the mounting bracket 430 ensures high consistency in dual-wire processing, avoids manual adjustment or multiple positioning operations, and significantly improves the stability of wire harness crimping quality.

[0084] This application also provides a wire harness assembly line that uses the above-mentioned terminal crimping device, or a wire harness assembly line that uses the above-mentioned terminal crimping equipment containing the terminal crimping device provided in this application.
