[0002] In existing technologies, before crimping the wire core to the terminal, the ends of the wire core need to be pre-treated, such as by stripping the insulation layer, before the terminal can be crimped onto the exposed metal wire. However, current terminal crimping mechanisms lack a structure for pre-treating the wire core; the pre-treatment mechanism and the crimping mechanism are separate structures. That is, the current practice is to use a stripping machine to centrally process the wire cores, and then transport the stripped wire cores to the terminal crimping machine for centralized terminal crimping. When facing production line-style wire harness assembly, the current processing method has many shortcomings: First, the separate equipment layout requires the wire cores to be transferred multiple times, increasing production steps and easily causing damage during transfer; second, the separation of pre-treatment and crimping processes requires repeated positioning, increasing the difficulty of equipment debugging and affecting the consistency of processing accuracy; third, the dispersed equipment occupies a large amount of production space, which is not conducive to a compact production line layout; finally, this segmented processing mode makes it difficult to achieve continuous automated production, restricting the improvement of overall production efficiency.

[0023] 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.

[0024] Reference Figures 1 to 5This utility model provides a terminal crimping device, wherein the terminal crimping device applies the terminal crimping device based on integrated wire core pretreatment proposed in this application.

[0025] Specifically, such as Figure 1 As shown, the terminal crimping device includes a pre-processing unit 100 and a crimping unit 300. The pre-processing unit 100 includes a stripping mechanism and a twisting mechanism. The stripping mechanism is used to remove the insulation layer at the end of the wire core, and the twisting mechanism is used to twist the exposed metal wire into strands. The crimping unit 300 is disposed at one end of the pre-processing unit 100 and includes a terminal feeding mechanism 200 and a crimping mechanism. The terminal feeding mechanism 200 feeds the terminals to the crimping mechanism, and the crimping mechanism fixes the terminals to the wire core.

[0026] Understandably, a stripping mechanism refers to a device that mechanically cuts off the insulation layer of the wire core. Specifically, this can be achieved using a set of cutting blades with adjustable spacing, which simultaneously cut both sides of the wire core to complete a circumferential cut. A twisting mechanism refers to a device that rotates and twists the exposed wire. Specifically, this can be achieved using a drive assembly with a rotating clamp. The clamp holds the end of the wire and rotates it to form a tightly twisted structure. A crimping mechanism refers to a device that combines the terminal with the wire core conductor. Specifically, this can be achieved using a hydraulic stamping assembly with an adjustable die. The closing of the die generates pressure, creating a mechanical connection between the terminal and the wire.

[0027] That is, after the wire core enters the pretreatment unit 100, the stripping mechanism first positions and cuts the insulation layer, and then the twisting mechanism rotates and twists the exposed wire to form a regular conductor bundle. The pretreated wire core directly enters the crimping unit 300, where the terminal feeding mechanism 200 transports the terminal to the crimping position. The crimping mechanism then uses a mold to close and crimp the terminal to the conductor bundle. The entire process is completed continuously in a single device, without the need to transfer the wire core to another station, and the processing position reference remains consistent.

[0028] Advantageously, compared to existing technologies, separate equipment requires independent stripping and crimping machines, and the wire cores need to be transferred and repositioned between the two machines. This application integrates the pretreatment and crimping processes into a single device through integrated design, eliminating positioning errors caused by wire core transfer. Furthermore, traditional separate equipment requires material transfer mechanisms and reserved equipment spacing, while this application reduces the equipment footprint through optimized space layout, effectively reducing the space occupied by wire harness processing equipment and avoiding accuracy loss caused by repeated wire core positioning. Continuous operation of the pretreatment and crimping processes reduces material turnaround time and improves processing efficiency. At the same time, the integrated design simplifies the equipment structure, reduces the complexity of equipment debugging and maintenance, and improves the level of production line automation.

[0029] According to some embodiments of this application, such as Figure 5As shown, the stripping mechanism includes a first drive member 310 and a cutting blade 320. The cutting blade 320 is connected to the first drive member 310, and the first drive member 310 can drive the cutting blade 320 to move closer to or away from the wire core.

[0030] Understandably, the output end of the first driving component 310 is fixed to the cutting blade 320 via a rigid connector. When the wire core is positioned at the preset station, the first driving component 310 pushes the cutting blade 320 towards the surface of the wire core in a direction perpendicular to the wire core axis. After the cutting edge of the cutting blade 320 contacts the outer surface of the wire core, it completes the insulation layer cutting within a preset stroke range. Subsequently, the first driving component 310 moves in the opposite direction to reset the cutting blade 320. During this process, the movement trajectory of the cutting blade 320 is controlled by the stroke accuracy of the driving component, without relying on an external positioning mechanism, thus ensuring the consistency of the cutting depth.

[0031] Specifically, in some embodiments of this application, the stripping mechanism and the twisting mechanism are spaced apart along the extension direction of the wire core axis, and two cutting blades 320 are disposed opposite to each other on both sides of the wire core.

[0032] Understandably, the stripping mechanism and the twisting mechanism are arranged at intervals along the axial direction, and the cutting blades 320 are symmetrically arranged on both sides of the wire core. When the wire core is conveyed along the axial direction, the stripping mechanism simultaneously completes the insulation layer cutting through the cutting blades 320 on both sides. Subsequently, the wire core continues to move to the twisting mechanism to complete the wire twisting, maintaining the consistency of the axial positioning reference of the wire core and avoiding repeated positioning errors.

[0033] Or, in some other embodiments of this application, such as Figure 5 As shown, the stripping mechanism and the twisting mechanism are arranged side by side in a direction perpendicular to the wire core axis. The stripping mechanism also includes an L-shaped connector 330, one end of which is connected to the first drive member 310, and the cutting blade 320 is connected to the other end of the connector.

[0034] It is understandable that the L-shaped connector 330 refers to a mechanical connection component with a bent structure, which can be implemented by using a metal sheet or casting with a right-angle bend. The mechanism avoids obstacles by changing the spatial positional relationship between the drive component and the cutting blade 320.

[0035] That is, the peeling mechanism and the twisting mechanism are arranged side by side in the vertical axis direction. The L-shaped connector 330 changes the movement direction of the drive component from the vertical axis to the parallel axis, so that the cutting blade 320 can complete the cutting action on the side of the wire core. At the same time, it leaves axial operating space for the twisting mechanism. Through vertical staggered arrangement, the mechanism is compacted while ensuring processing accuracy.

[0036] Beneficially, compared with existing technologies, traditional equipment typically employs a single linear layout or disordered arrangement for the stripping and twisting mechanisms, leading to excessive equipment length or interference issues. The two layout schemes for the stripping and twisting mechanisms proposed in this application address different equipment form requirements. The former maintains processing continuity through axial spacing, while the latter achieves space compression through L-shaped connectors 330. This effectively solves the problems of low space utilization and difficulty in achieving processing accuracy in traditional equipment, realizing a coordinated spatial layout for the stripping and twisting processes. While ensuring wire core positioning accuracy, it significantly reduces the volume of the pre-processing unit 100, allowing the wire core pre-processing and terminal crimping processes to be integrated into the same equipment. The two layout schemes respectively adapt to the design requirements of long-line equipment and compact equipment, providing flexible choices for different production scenarios, while avoiding the accuracy loss caused by multiple positioning in traditional split-type equipment.

[0037] As a further improvement to the plan, such as Figure 5 As shown, the peeling mechanism also includes a slide rail assembly, which includes a guide rail 340 and a slider 350. The slider 350 is slidably connected to the guide rail 340. The output end of the first drive member 310 is connected to one end of the slider 350, and the connector or cutter 320 is connected to the other end of the slider 350.

[0038] Understandably, the slide rail assembly, through the cooperation of the guide rail 340 and the slider 350, converts the linear driving force of the first drive member 310 into the precise movement of the cutting blade 320 along a predetermined path. When the first drive member 310 is activated, its output end pushes the slider 350 to slide along the guide rail 340, causing the cutting blade 320 or the connecting member to move synchronously. The rigid guiding effect of the guide rail 340 limits the lateral deviation of the cutting blade 320 during movement, ensuring that the cutting blade 320 always cuts into the insulation layer in a direction perpendicular to the wire core axis. The sliding stroke of the slider 350 is limited by the length of the guide rail 340, preventing damage to the wire core due to excessive displacement of the cutting blade 320. Through the constraint of the slide rail assembly, the cutting blade 320 maintains a stable cutting angle and depth as it approaches the wire core, thereby eliminating positioning deviations caused by mechanical backlash or vibration.

[0039] Beneficially, this application forcibly constrains the movement trajectory of the cutting blade 320 through the slide rail assembly, ensuring that the cutting blade 320 can only move along the direction defined by the guide rail 340, significantly improving movement stability. Furthermore, the slide rail assembly separates the power transmission path of the driving component from the guiding path, avoiding the influence of the driving component's own clearance on cutting accuracy, achieving high-precision positioning of the cutting blade 320 during the stripping process, and solving the problem of uneven insulation layer cutting depth caused by unstable movement. The rigid guiding characteristics of the slide rail assembly effectively suppress the vibration and offset of the cutting blade 320 during movement, ensuring precise and controllable relative position between the cutting blade 320 and the wire core. Therefore, the insulation layer at the end of the wire core is uniformly stripped, maintaining the integrity of the metal conductor and providing a reliable pre-treatment foundation for subsequent twisting and crimping processes.

[0040] Specifically, regarding the first embodiment of the twisting mechanism, as follows: Figure 5 As shown, the twisting mechanism includes a first clamping assembly 360 and a rotary drive 370. The first clamping assembly 360 is connected to the output end of the rotary drive 370. The first clamping assembly 360 is used to clamp the end of the wire core. The rotary drive 370 can drive the first clamping assembly 360 to rotate so that the metal wire at the end of the wire core is twisted into a strand.

[0041] It is understood that the first clamping component 360 refers to a mechanical clamping device used to fix the end of the wire core. Specifically, it can be implemented using a pneumatic clamp or an electric clamp. Its clamping surface can be provided with anti-slip texture to enhance clamping stability and prevent displacement of the wire core during the twisting process through clamping action. The rotary drive component 370 refers to a drive device that provides rotational power. Specifically, it can be implemented using a servo motor or a stepper motor. Its output shaft is connected to the first clamping component 360 through a coupling. By controlling the rotation angle and speed of the motor, the precise twisting of the metal wire at the end of the wire core is achieved.

[0042] That is, after the insulation layer is removed from the end of the wire core by the stripping mechanism, the first clamping assembly 360 clamps the exposed metal wire segment, and the rotary drive 370 drives the clamping assembly to rotate around the wire core axis. Under the action of circumferential torsional force, the metal wire gradually forms a tight strand structure. Since the clamping assembly and the rotary drive 370 are directly connected, the rotational torque can be transmitted to the wire core without loss, avoiding uneven torsion caused by complex transmission structure. For example, when the servo motor rotates at a set speed, the clamping assembly drives the end of the wire core to rotate synchronously, and the metal wire forms a shape that meets the crimping requirements in continuous torsion.

[0043] Advantageously, this application enables the direct twisting and stranding of metal wires during the core pre-processing stage, avoiding the loss of positioning accuracy caused by separate equipment and ensuring the stability of the stranded core shape. The precise speed control of the rotary drive 370 can adapt to the twisting requirements of wires with different diameters; for example, a low speed is used for thin wires to prevent breakage, while a high speed is used for thick wires to improve processing efficiency. The rigid connection structure of the clamping assembly further ensures no displacement at the core end during twisting, providing a well-formed metal wire foundation for subsequent terminal crimping.

[0044] As a further improvement to the solution, the twisting mechanism also includes a translation component, which includes a mounting base 380 and a second drive member 390. A rotary drive member 370 is mounted on the mounting base 380, and the output end of the second drive member 390 is connected to the mounting base 380. The translation component can drive the first clamping component 360 to reciprocate linearly along the extension direction of the wire core axis.

[0045] Understandably, after the second drive unit 390 is activated, its output end pushes the mounting base 380 to move along a preset track, causing the rotary drive unit 370 and the first clamping assembly 360 to move synchronously. After the first clamping assembly 360 clamps the insulation layer at the end of the wire core, the first drive unit 310 is activated and drives the cutting blade 320 to approach the wire core. The cutting blade 320 cuts the insulation layer along the processing path, causing the insulation layer at the end of the wire core to separate from the insulation layer of the main body of the wire core. Subsequently, the rotary drive unit 370 and the second drive unit 390 are activated simultaneously. The second drive unit 390 drives the rotary drive unit 370 and the first clamping assembly 360 to move in a direction away from the main body of the wire core.

[0046] That is, it can be understood that the second driving member 390 and the rotary driving member 370 work together to make the first clamping assembly 360 rotate and retract while clamping the insulation layer at the end of the wire core. This allows the insulation layer to be peeled off while the wire core is twisted into strands by friction between the insulation layer and the wire core during rotation. This simplifies the equipment structure, reduces the need for additional positioning devices, and enables continuous operation of wire core pretreatment and crimping processes. It also avoids repetitive positioning actions between separate equipment and improves processing accuracy and production efficiency.

[0047] According to some embodiments of this application, such as Figure 1 As shown, the crimping mechanism includes a crimping module 400 and a flipping module 500. The crimping module 400 is connected to the flipping module 500. The crimping module 400 can receive terminals and crimp and fix the terminals onto the wire core. The flipping module 500 can drive the crimping module 400 to rotate, so that the crimping module 400 can switch positions between the terminal feeding mechanism 200 and the pre-processing unit 100.

[0048] It is understandable that the crimping module 400 refers to the functional unit used to complete the crimping action between the terminal and the wire core. Specifically, it can be implemented using a crimping seat with an adjustable crimping block 420. The crimping block 420 expands and contracts the crimping hole through the linear movement of the driving component, thereby adapting to different terminal sizes. It directly fixes the relative position of the terminal and the wire core through physical contact, avoiding the positioning deviation caused by terminal transfer in traditional split equipment. The flipping module 500 refers to the rotating mechanism that realizes the spatial position switching of the crimping module 400. Specifically, it can be implemented using a mechanical structure with a flipping bracket 510 and a rotating driving component 370. The rotation axis of the flipping bracket 510 matches the center of gravity of the crimping module 400, ensuring stability during rotation. This module enables the crimping module 400 to accurately switch between the terminal feeding station and the wire core pre-processing station through angle control, eliminating the need for repetitive positioning caused by the split equipment.

[0049] In this application, after the crimping module 400 receives the terminals conveyed by the terminal feeding mechanism 200 at the terminal feeding station, the flipping module 500 drives the crimping module 400 to rotate to the position where the wire core is located after the pre-processing unit 100 has completed stripping and twisting. At this time, the exposed metal section of the wire core is pushed into the crimping hole of the crimping module 400, and the crimping block 420 closes under the action of the driving component to complete the crimping of the terminal and the wire core. After the crimping is completed, the flipping module 500 drives the crimping module 400 back to the terminal feeding station for the next cycle. In this process, the receiving and crimping functions of the crimping module 400 are realized through the same structure, and the rotation path of the flipping module 500 is optimized so that the switching time between the two stations is compressed into a single rotation cycle.

[0050] Beneficially, compared with existing technologies, traditional solutions require manual or robotic transfer of pre-treated wire cores to independently installed crimping equipment, which not only increases handling time but also leads to cumulative errors due to multiple positioning steps. This application integrates the crimping module 400 and the flipping module 500, creating a spatial closed loop between the terminal crimping process and the wire core pre-treatment process. The position switching of the crimping module 400 directly replaces the transfer process of the wire core or terminal, reducing the connection links between equipment and solving the problem of repeated positioning caused by the separation of the crimping mechanism and the pre-treatment mechanism. Seamless connection between processes is achieved through modular rotation switching, reducing equipment space occupancy. The synergistic effect of the crimping module 400 and the flipping module 500 allows the terminal crimping accuracy to be controlled by a single mechanism, avoiding positioning errors caused by multiple equipment connections, while shortening process changeover time and improving the automation level of wire harness assembly.

[0051] Specifically, such as Figure 2 and Figure 3As shown, the flip module 500 includes a flip bracket 510 and a flip drive 520. The crimping module 400 is mounted on the flip bracket 510. The output end of the flip drive 520 is connected to the flip bracket 510. The flip drive 520 can drive the flip bracket 510 to rotate so as to realize the position switching of the crimping module 400 between the terminal feeding mechanism 200 and the pre-processing unit 100.

[0052] Understandably, when the flip drive 520 receives a station switching command, it drives the flip bracket 510 to rotate around its axis by outputting torque through the reducer. The crimping module 400 rotates synchronously with the flip bracket 510 to the terminal loading station, where the terminal is accurately fed into the clamping area of ​​the crimping module 400. After the terminal is clamped, the flip drive 520 drives the flip bracket 510 to rotate in the opposite direction, precisely transferring the crimping module 400 to the wire core processing station. During the flipping process, the rigid structure of the flip bracket 510 prevents the flexible deformation of the multi-joint robotic arm, and its rotation trajectory is controlled by the encoder of the drive unit in a closed loop, ensuring that the repeatability of the positioning accuracy during each station switching is controlled within the preset tolerance range.

[0053] Beneficially, this application eliminates positioning deviations caused by joint clearances in the robotic arm by rigidly integrating the crimping module 400 with the flipping bracket 510. In existing technologies, separate drive mechanisms require independent control of rotation and lifting movements, while this application uses a single rotary drive source to achieve station switching, reducing the number of motion control nodes, avoiding multi-axis coordination errors, and effectively solving the problem of decreased positioning accuracy caused by the complex structure of the crimping module 400 during station switching. The direct drive between the flipping bracket 510 and the drive component simplifies the mechanical structure and reduces equipment manufacturing costs. The rigid connection design between the crimping module 400 and the bracket ensures motion stability during station switching, significantly improving the docking accuracy between the terminal and the wire core, and shortening the station switching time to meet the demands of high-speed continuous production.

[0054] Furthermore, such as Figure 4 As shown, the crimping module 400 includes a fixed base 410, a crimping block 420, and a crimping drive. Multiple crimping blocks 420 are circumferentially arranged to form crimping holes. At least one crimping block 420 is interactively connected to the fixed base 410. The movable crimping block 420 is connected to the crimping drive, which can drive the crimping block 420 away from or closer to the crimping hole.

[0055] It is understandable that when multiple crimping blocks 420 are closed, they form crimping holes that match the shape of the terminal, and the hole diameter can be adjusted by changing the spacing between adjacent crimping blocks 420.

[0056] Specifically, when the terminal enters the crimping module 400, the crimping drive unit drives the movable crimping block 420 to move towards the center of the crimping hole according to preset parameters. Multiple crimping blocks 420 simultaneously retract to form a closed space matching the terminal size. During crimping, the circumferentially distributed crimping blocks 420 apply uniform radial pressure to the terminal, ensuring a force balance on the contact surface between the terminal and the wire core. When a terminal specification needs to be changed, the crimping drive unit moves in the opposite direction, causing the crimping blocks 420 to expand outwards, thus increasing the diameter of the crimping hole. After the new specification terminal is positioned, the closing action is repeated. Through independent control of at least one movable crimping block 420, continuous processing of terminals of different sizes can be achieved without changing the mold.

[0057] In some specific embodiments, the number of pressing blocks 420 can be set to four, two of which are connected to the fixed base 410 via slide rails and are synchronously driven by the pressing drive, while the other two are rigidly connected to the fixed base 410 to form a reference positioning surface. The pressing drive can be a double-rod cylinder, whose piston rod is connected to the movable pressing block 420 via a linkage mechanism to achieve bidirectional synchronous movement.

[0058] Beneficially, this application, through its adjustable crimping hole structure, allows for adaptation to various terminal specifications simply by adjusting the position of the crimping block 420, eliminating the need for mold replacement and avoiding crimping misalignment caused by mold clearance errors. Furthermore, it enables the crimping module 400 to adjust the crimping hole diameter in real time according to the terminal shape, ensuring uniform distribution of the covering force on the terminal during crimping and solving the problem of terminal deformation or weak crimping caused by mismatched hole diameters. The modular adjustable structure enables a single device to handle multiple terminal specifications, reducing the number of devices required and maintenance costs, and improving the flexible production line capability.

[0059] According to some embodiments of this application, a wire core feeding unit 600 is also provided. Specifically, as shown in the embodiments of this application... Figure 1 and Figure 2 As shown, the wire core feeding unit 600 includes a third driving member 610 and a second clamping assembly 620. The second clamping assembly 620 is connected to the third driving member 610. The third driving member 610 can drive the second clamping assembly 620 away from or near the crimping mechanism so that the wire core is sleeved with the terminal.

[0060] It is understood that the third driving component 610 refers to the power device used to control the linear movement of the second clamping assembly 620. Specifically, it can be implemented using a linear motor or a cylinder. Its output end is rigidly connected to the second clamping assembly 620, and its travel distance is set through programming or mechanical limiting. The second clamping assembly 620 refers to the mechanical structure used to fix the wire core. Specifically, it can be implemented using pneumatic grippers or electromagnetic clamps. Its clamping surface can be provided with anti-slip textures or elastic material to increase friction. The combined structure of the third driving component 610 and the second clamping assembly 620 ensures that the wire core moves precisely along the axial direction to the crimping station after pretreatment, avoiding positioning deviations caused by handling multiple devices.

[0061] That is, the wire core is clamped and fixed by the second clamping assembly 620. After stripping and twisting are completed, the third driving component 610 drives the second clamping assembly 620 to move along a preset path toward the crimping mechanism. When it moves to the set position, the exposed metal wire segment of the wire core is axially aligned with the terminal conveyed by the terminal feeding mechanism 200, at which point the crimping mechanism performs the crimping action. During this process, the movement path of the wire core and the spatial position of the crimping station are matched through mechanical linkage, without the need for manual intervention or repeated calibration.

[0062] Beneficially, this application integrates the wire core feeding unit 600, enabling the pretreatment and crimping processes to be completed within the same device. Existing technologies rely on manual handling or robotic transfer between separate equipment, resulting in low positioning efficiency and insufficient automation. Simultaneously, through the coordinated control of the third drive component 610 and the second clamping assembly 620, continuous and precise positioning of the wire core from pretreatment to crimping is achieved, resolving the problem of repetitive positioning caused by the separation of wire core pretreatment and crimping processes. The integrated conveying mechanism ensures the axial alignment accuracy of the wire core and the terminal, avoiding the accumulation of positioning errors between multiple devices. Furthermore, the linkage control of the third drive component 610 and the second clamping assembly 620 enables automatic conveying and splicing of the wire core, reducing manual intervention and improving the automation level of the production process.

[0063] In addition, this application also provides a terminal crimping device that uses the above-mentioned terminal crimping apparatus, such as... Figure 1 As shown, two crimping devices are arranged side by side to simultaneously pre-process and crimp the ends of the same wire core, or simultaneously pre-process and crimp the ends of two different wire cores, effectively improving production efficiency and automation.

[0064] Furthermore, this application also provides a wire harness assembly line that utilizes the aforementioned terminal crimping device. By utilizing the aforementioned terminal crimping device, the compactness and automation level of the wire harness assembly line are improved, and the space occupied by the equipment is reduced through functional integration.
