Description

Technical Field

[0001] This application relates to the field of stranding technology, and in particular to a transfer device and a stranding machine. Background Technology

[0002] Typically, the transfer device of a stranding machine picks up the conductor by moving the grippers, and then sequentially passes it through a stripping mechanism for stripping, a bolting mechanism for bolting, and a crimping mechanism for crimping before handing it over to the stranding mechanism for stranding. However, this method involves multiple transfer steps, is time-consuming, and has low work efficiency. Summary of the Invention

At least the portion of the guide rod located within the sliding groove and the moving groove is cylindrical. The width of the moving groove is greater than the outer diameter of the portion of the guide rod located within the moving groove.

[0018] A slide rail is provided on the base and extends along a fourth preset direction. The fixed clamping arm is slidably connected to the slide rail.

[0019] A limiting block is disposed on the base and has a limiting groove that extends along the fourth preset direction.

[0020] A limiting pin is slidably disposed within the limiting groove, and the limiting pin is connected to the fixed clamping arm.

[0021] A telescopic spring, one end of which is connected to the fixed clamping arm and the other end of which is connected to the base, is used to apply a driving force to the fixed clamping arm so that the fixed clamping arm can move along the fourth preset direction away from the base;

[0022] A driving module is disposed on the base and connected to the slider. The driving module is used to drive the slider to move along the fourth preset direction. The fourth preset direction, the third preset direction and the preset axis are arranged perpendicular to each other.

[0023] In some embodiments of the first aspect, the number of the sub-grippers is two, the gripper has a preset plane, the two sub-grippers are symmetrically arranged about the preset plane, and the preset plane is perpendicular to a first preset direction.

[0024] In some embodiments of the first aspect, the driving member is used to drive the gripper to move along the first preset direction; wherein the movement paths of adjacent grippers are arranged in parallel and offset order.

[0025] In some embodiments of the first aspect, the first preset direction, the second preset direction, and the third preset direction are all horizontally arranged, and the fourth preset direction is vertically arranged.

[0026] In some embodiments of the first aspect, the number of grippers is four.

[0031] The embodiments of this application have the following advantages:

[0032] This application provides a transfer device that, by employing a configuration of multiple grippers and driving components, allows the wire stripping, threading, and crimping stations to simultaneously process wire harnesses transferred by different grippers, reducing the waiting time for wire transfer between different stations. This enables a continuous and smooth workflow, significantly improving the overall efficiency of the production line. Furthermore, the new design allows stripping, threading, and crimping processes to be completed directly while the wire harness is gripped, without the need to frequently transfer the wire harness from one gripper to another or to another mechanism. This not only simplifies mechanical movements but also reduces the possibility of errors. Moreover, since adjacent grippers can approach each other to form a pre-set handover station, and each gripper is controlled by an independent driving component, multiple grippers can cooperate to transfer wire harnesses between multiple stations.

[0033] This application also relates to a stranding machine. Since the above-mentioned transfer device has the above-mentioned technical effects, the stranding machine including the transfer device should have the same technical effects, which will not be described in detail here.

[0053] In related technologies, the transfer device of a stranding machine picks up the conductor by moving the grippers, and then sequentially passes it through a stripping mechanism for stripping, a bolting mechanism for bolting, and a crimping mechanism for crimping before handing it over to the stranding mechanism for stranding. However, this method involves multiple transfer processes, is time-consuming, and has low work efficiency.

[0054] As shown in Figure 1, Figure 2 , Figure 3 , Figure 4As shown in Figure 5, in order to solve the above-mentioned technical problems, this application provides a transfer device 100. The transfer device 100 includes a plurality of grippers and a plurality of driving members 120. The plurality of grippers are arranged sequentially in a first preset direction. The grippers are used to hold wire harnesses. At least one of the adjacent grippers is connected to a driving member 120. The plurality of driving members 120 are respectively used to drive the corresponding grippers to move, so that the adjacent grippers can move closer or further away from each other in the first preset direction. The proximity of any adjacent grippers can form a preset handover station between them. The adjacent grippers located at the preset handover station can respectively hold different parts of the same wire harness. The transfer device 100 is configured with a wire stripping station, a bolt threading station and a crimping station. The wire stripping station, bolt threading station and crimping station are spaced apart in the first preset direction. The wire stripping station, bolt threading station and crimping station are respectively located within the movement range of the corresponding grippers.

[0055] In these embodiments, the technical solutions provided in this application aim to optimize the transfer device 100 of the stranding machine to improve production efficiency. Specifically, firstly, multiple grippers work collaboratively, that is, multiple grippers are arranged sequentially in a first preset direction. These grippers can move independently, but can also work together. This design allows for a more flexible operating process and reduces the transfer time and waiting idle time of a single workpiece (i.e., wire harness) from one process to another.

[0056] For example, in this embodiment, the gripper is a parallel gripper. Of course, in other embodiments, the gripper is set as a swing gripper, which is not specifically limited here, as long as it can clamp the wire harness.

[0057] Secondly, the precise control supported by the drive unit 120, with at least one drive unit 120 connected to each or each pair of adjacent grippers, allows the grippers to move relative to each other in a first preset direction, i.e., closer or farther apart. Clearly, this allows for the adjustment of the gripper positions as needed to create specific work areas, such as wire stripping stations, bolt insertion stations, and crimping stations. Furthermore, by ensuring that any two adjacent grippers can cooperate to clamp different parts of the same wire, an effective handover point is formed, enabling transfer between adjacent grippers and further improving processing speed and accuracy.

[0058] For example, the driving component 120 includes a first driving module 1517 and a second driving module 1517. The first driving module 1517 is connected to the gripper and is used to drive the gripper to move vertically. The second driving module 1517 is connected to the first driving module 1517 and is used to drive the gripper to move along a first preset direction. The first preset direction is a horizontal straight line direction. Thus, by setting the movement range of the gripper, adjacent grippers can avoid each other and dock.

[0059] Furthermore, by aligning key processes such as wire stripping, bolt threading, and crimping along a straight line and within the reach of the grippers, the entire processing can be completed without altering the overall equipment layout, greatly simplifying the operation. Simultaneously, since each workstation is within the reach of its corresponding gripper, no additional time is required for workstation switching, significantly improving work efficiency.

[0060] It should be noted that the wire stripping station, the bolting station, and the crimping station are three important process steps on the stranding machine production line, and each station has its specific function and role.

[0061] A wire stripping station removes the insulation from one or both ends of a wire to expose the internal metallic conductor. Mechanical blades or thermal strippers are typically used to cut and peel off the insulation material. This applies to different types of wires (such as single-core or multi-core). For example, a wire stripping station may be equipped with a stripping device to perform the stripping operation on wire bundles transported by grippers.

[0062] At the wire threading station, bare wires are inserted into pre-prepared terminal connectors (typically metal pieces with holes). Grippers accurately feed the stripped wires into the holes of the terminal connectors. This process involves precise positioning and appropriate force control to ensure the wires are fully threaded without damage. Proper threading ensures the safety and reliability of the electrical connection, while also guaranteeing sufficient mechanical strength at the joint. For example, the threading station may be equipped with a threading device capable of threading stripped wire bundles transported by the grippers.

[0063] The crimping station is responsible for securing the wires inserted into the connector and applying pressure to ensure a tight bond between the connector and the wires. Using specialized crimping tools or dies, the connector is compressed under pressure, allowing the metal parts inside the connector to firmly encase the wires. This not only enhances electrical contact performance but also improves water and dust resistance. Effective crimping provides a stable electrical connection and increases the overall durability of the assembly, reducing the potential failure rate in the future. For example, the crimping station is equipped with a crimping device capable of crimping wire harnesses that have been transferred by grippers and threaded through the connector.

[0064] Therefore, by reducing unnecessary mechanical movements and shortening the waiting time between each process step, this application not only speeds up the entire production cycle but also reduces energy consumption and maintenance costs, ultimately achieving the goal of improving overall production efficiency.

[0065] In some embodiments, the gripper includes a sub-gripper 151, which has a connecting end and multiple clamping ends. The multiple clamping ends are spaced apart in a second preset direction, and each clamping end can clamp different parts of the same wire harness. The connecting end is connected to the drive member 120.

[0066] In these embodiments, the gripper design is further optimized to improve its functionality and flexibility. Specifically, this gripper includes a sub-gripper 151. The connecting end is the portion where the sub-gripper 151 is connected to the drive member 120, through which the drive member 120 can control the movement and operation of the sub-gripper 151.

[0067] Multiple clamping ends are located in a second preset direction and are spaced apart from each other. This means that each clamping end can independently clamp different parts of the same wire harness. Obviously, by having multiple clamping ends act on different positions of a wire harness simultaneously, the wire harness can be more firmly fixed, reducing shaking or displacement during processing, thereby improving process accuracy and facilitating the handover of the wire harness between adjacent clamps.

[0068] In other words, multi-point clamping within a single gripper simplifies the transfer process from one workstation to another, as it eliminates the need to completely release and re-clamp the wire harness; only the position of the clamping ends needs adjustment. This reduction in re-clamping frequency makes the entire production process more continuous and streamlined, thereby improving overall work efficiency. Furthermore, this sub-gripper 151 design better suits the needs of wire stripping, threading, and crimping stations, ensuring that each process step is completed efficiently and accurately. This multi-point clamping structure is particularly useful when different parts of the wire need to be processed simultaneously.

[0069] For example, in this embodiment, there are two clamping ends. Of course, in other embodiments, the number of clamping ends may be three, four, five, six, etc.

[0070] like Figure 3 and Figure 4 As shown, in some embodiments, the sub-gripper 151 includes a plurality of gripping arm assemblies 1511 and a power unit. The plurality of gripping arm assemblies 1511 are arranged side by side at intervals in a second preset direction. Each gripping arm assembly 1511 includes two gripping arms, and a clamping opening is formed between the two gripping arms of the same gripping arm assembly 1511. The power unit has a driving end and a fixed end. The driving end is connected to the gripping arms. The driving end can drive the two gripping arms of the same gripping arm assembly 1511 to move away from or closer to each other, and the fixed end is connected to the driving member 120.

[0071] In these embodiments, the design of the sub-clamp 151 is further refined, comprising multiple clamping arm assemblies 1511 and a power unit. This design provides finer control and wider adaptability, with each clamping arm assembly 1511 comprising two clamping arms. A jaw is formed between these two clamping arms for clamping the wire harness. Multiple such clamping arm assemblies 1511 are arranged side-by-side at intervals in a second predetermined direction, meaning they can be arranged along the length of the wire to form multiple clamping ends, thereby clamping different portions of the wire.

[0072] For example, in this embodiment, there are two clamping arm assemblies 1511. Of course, in other embodiments, the number of clamping arm assemblies 1511 may be three, four, five, etc.

[0073] The power unit is connected to the clamping arms in each clamping arm assembly 1511, enabling it to drive the two clamping arms closer together or further apart. The power unit is connected to the drive unit 120, ensuring stable installation and control of the entire power unit. When clamping a wire, the power unit brings the two clamping arms within the same clamping arm assembly 1511 closer together, thereby closing the clamp and firmly gripping the wire. Conversely, when releasing the wire or moving it to the next station, the power unit moves the clamping arms further apart, opening the clamp and releasing the wire. Since the multiple clamping arm assemblies 1511 are arranged along a second preset direction, this allows for independent control of different sections of the same wire, enhancing operational flexibility and precision.

[0074] For example, the power unit is a pneumatic cylinder, and the housing of the piston rod of the pneumatic cylinder is respectively connected to a clamping arm. The opening and closing action between a pair of clamping arms is realized by the extension and retraction of the piston rod.

[0075] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the power unit includes a base, a guide block 1515, a slider 1514, a limiting block 1520, a limiting pin 1519, a telescopic spring 1522, and a drive module 1517. The base has a preset axis, which is parallel to the second preset direction. The two clamping arms of the same clamping arm group 1511 are a fixed clamping arm 15112 and a movable clamping arm 15111. The movable clamping arm 15111 is hinged to the base and can rotate around the preset axis to move the movable clamping arm 15111 away from or close to the fixed clamping arm 15112.

[0076] The guide block 1515 has a guide groove 15151, which extends along an arc direction. The axis of the guide groove 15151 coincides with the preset axis, and the plane containing the arc direction is perpendicular to the second preset direction.

[0077] The slider 1514 has a groove 15141, which extends along a third preset direction;

[0078] The guide rod 1513 has an axis, which is parallel to a preset axis. The fixed clamping arm 15112 has a moving groove 1512, which extends along a third preset direction. The guide rod 1513 is disposed on the movable clamping arm 15111. One end of the guide rod 1513 is movably inserted into the slide groove 15141, and the other end of the guide rod 1513 is movably inserted into the moving groove 1512. The portion of the guide rod 1513 located at least within the slide groove 15141 and the moving groove 1512 is cylindrical. The width of the moving groove 1512 is greater than the outer diameter of the portion of the guide rod 1513 located within the moving groove 1512.

[0079] The slide rail 1523 is disposed on the base and extends along the fourth preset direction. The fixed clamping arm 15112 and the slide rail 1523 are slidably connected.

[0080] A limiting block 1520 is disposed on the base, and the limiting block 1520 has a limiting groove 1521, which extends along a fourth preset direction.

[0081] The limiting pin 1519 is slidably inserted into the limiting groove 1521, and the limiting pin 1519 is connected to the fixed clamping arm 15112.

[0082] One end of the telescopic spring 1522 is connected to the fixed clamping arm 15112, and the other end of the telescopic spring 1522 is connected to the base. The telescopic spring 1522 is used to apply a driving force to the fixed clamping arm 15112, so that the fixed clamping arm 15112 can move along the fourth preset direction to move away from the base.

[0083] The drive module 1517 is mounted on the base and is connected to the slider 1514. The drive module 1517 is used to drive the slider 1514 to move along the fourth preset direction. The fourth preset direction, the third preset direction and the preset axis are set perpendicular to each other.

[0084] In these embodiments, the power unit is a complex mechanical structure used to control the opening and closing movements of the clamping arm assembly 1511. The following is a detailed description of the components of this power unit and their functions:

[0085] Base and movable clamping arm 15111: The preset axis on the base is parallel to the second preset direction, providing a rotation center for the movable clamping arm 15111. The movable clamping arm 15111 is connected to the base by a hinge, allowing it to rotate around the preset axis, thereby enabling it to move closer to or away from the fixed clamping arm 15112.

[0086] For example, the movable clamping arm 15111 has a hinge hole 1518, and the base is provided with a rotating shaft 1516, which passes through the hinge hole 1518 to achieve hinge.

[0087] Guide block 1515 and arc-shaped guide groove 15151: The guide groove 15151 on the guide block 1515 extends in an arc direction, and the axis of the guide groove 15151 coincides with the preset axis, ensuring that the movable clamping arm 15111 can move along a predetermined path when rotating around the preset axis. The plane containing the arc direction is perpendicular to the second preset direction, ensuring that the rotational movement of the movable clamping arm 15111 is not affected by other directions.

[0088] Slider 1514 and groove 15141: The groove 15141 on slider 1514 extends along a third preset direction, which is perpendicular to both the preset axis and the fourth preset direction, ensuring that slider 1514 can move in an independent direction. The groove 15141 is movably engaged with one end of guide rod 1513, so that when slider 1514 moves, the fixed clamping arm 15112 can be moved together through guide rod 1513.

[0089] Guide rod 1513 and actuating groove 1512: The portion of guide rod 1513 located within slide groove 15141 and actuating groove 1512 is cylindrical, ensuring good sliding performance. The width of actuating groove 1512 is greater than the outer diameter of guide rod 1513, allowing for a certain degree of relative displacement and facilitating adaptation to different clamping requirements. The axis of guide rod 1513 is parallel to a preset axis on the base, allowing guide rod 1513 to slide smoothly within slide groove 15141 without generating additional friction or interference.

[0090] For example, the guide rod 1513 is cylindrical. Alternatively, the guide rod 1513 and the movable clamping arm 15111 are integrated.

[0091] The slide rail 1523 and the fixed clamping arm 15112: The slide rail 1523 is set along the fourth preset direction, and the fixed clamping arm 15112 is slidably connected to the slide rail 1523, ensuring that the fixed clamping arm 15112 can move stably along a straight line. Since the fourth preset direction is perpendicular to the other two directions, the movement of the fixed clamping arm 15112 will not interfere with the operation of other components.

[0092] For example, the slide rail 1523 is configured as a guide plate, which is disposed on the base and passes through the slide rail groove 1524 on the fixed clamping arm 15112. The slide rail groove 1524 and the guide plate extend in the same direction, so that the two slide together.

[0093] Limiting block 1520 and limiting pin 1519: The limiting groove 1521 on the limiting block 1520 and the limiting pin 1519 work together to limit the maximum stroke of the fixed clamping arm 15112, preventing it from exceeding the safe range. This not only increases the safety of the system but also ensures the accuracy of the clamping action.

[0094] The function of the telescopic spring 1522: One end of the telescopic spring 1522 is connected to the fixed clamping arm 15112, and the other end is connected to the base. It applies a driving force to the fixed clamping arm 15112, enabling it to move along the fourth preset direction away from the base. The presence of the spring ensures that the system can maintain a certain initial state or help with automatic reset even when no external force is applied.

[0095] For example, in this application, the slide rail 1523 extends vertically, so that without external force, the telescopic spring 1522 drives the fixed clamping arm 15112 to rise.

[0096] It should be noted that when the sub-gripper 151 is in the open state, the telescopic spring 1522 is in the compressed state; when the sub-gripper 151 is in the closed state, the telescopic spring 1522 is in the compressed state.

[0097] Operation of drive module 1517: Drive module 1517 is mounted on the base and connected to slider 1514, responsible for driving slider 1514 to move along the fourth preset direction. Because the fourth preset direction is perpendicular to other directions, the action of drive module 1517 will not affect the movement in other directions, ensuring the coordination and stability of the entire system.

[0098] The third preset direction, the fourth preset direction (i.e. the driving direction of the driving end), and the preset axis are perpendicular to each other, forming a three-dimensional spatial coordinate system.

[0099] For example, the drive module 1517 is configured as a linear motion module. Of course, in other embodiments, it can also be configured as an electric actuator, a pneumatic cylinder, etc.

[0100] Taking the slide rail 1523 as an example of extending vertically, when the drive module 1517 starts working, it pushes the slider 1514 to move along a fourth preset direction. Since the slider 1514 is connected to the guide rod 1513, and the guide rod 1513 passes through the actuation groove 1512 on the fixed clamping arm 15112, the movement of the slider 1514 and the restoring force of the extension spring 1522 indirectly drive the fixed clamping arm 15112 to slide along the slide rail 1523 until the limiting pin 1519 reaches the end above the limiting groove 1521, at which point the fixed clamping arm 15112 stops. Simultaneously, due to the large gap between the actuation groove 1512 and the guide rod 1513, the movable clamping arm 15111 continues to rise. Furthermore, since the movable clamping arm 15111 is hinged to the base, and the guide rod 1513 is also mounted on the movable clamping arm 15111, the movement of the slider 1514 will also cause the movable clamping arm 15111 to rotate around a preset axis, ultimately achieving a closing action between the two arms in the clamping arm assembly 1511, that is, the fixed clamping arm 15112 and the movable clamping arm 15111 rise first and then clamp. In addition, the presence of the telescopic spring 1522 provides additional driving force for the fixed clamping arm 15112, ensuring that the system can drive the fixed clamping arm 15112 to rise even without external force. Throughout the process, the limiting system ensures that all movements are within a safe range, avoiding the risks caused by excessive movement.

[0101] Furthermore, the opening process is as follows: Since there is a very large gap between the guide rod 1513 and the actuation groove 1512, the movable clamping arm 15111 moves downward first, and the jaws open at a certain angle. At this time, the fixed clamping arm 15112 does not move downward until the guide rod 1513 contacts the lower part of the actuation groove 1512, which drives the fixed clamping arm 15112 to move downward, and the jaws complete the opening action. That is, the jaws open first and then descend.

[0102] like Figure 7 As shown, in some embodiments, there are two sub-grippers 151. The grippers have a preset plane, and the two sub-grippers 151 are symmetrically arranged about the preset plane. The preset plane is perpendicular to the first preset direction.

[0103] In these embodiments, the design of the grippers is further optimized. Specifically, this design includes two sub-grippers 151, and these two sub-grippers 151 are symmetrically arranged about a preset plane.

[0104] The grippers have a preset plane, which serves as a reference plane in the design. Two sub-grippers 151 are symmetrically positioned about this preset plane. This means that the structure on either side of the preset plane should be mirror-symmetrical. The preset plane is perpendicular to a first preset direction (typically the direction of wire movement). This symmetrical design ensures uniform force on both sides during clamping, reducing wire misalignment or damage caused by uneven force on one side. This uniform clamping force improves machining accuracy and quality.

[0105] Because of its symmetrical design, many components can share the same parts on both sides, simplifying the design and manufacturing process. Maintenance and replacement of parts are also much easier, as only one set of standard parts is needed.

[0106] The symmetrical dual-jaw design 151 can clamp a pair of wires simultaneously, further improving work efficiency. Furthermore, since the fixed clamping arms 15112 of the two jaws 151 are close to each other, they can be integrated into a single unit. Moreover, the fixed clamping arms 15112 are positioned between the movable clamping arms 15111, which reduces the size of the jaws and the spacing between a pair of wires.

[0107] like Figure 3 As shown, in some embodiments, the drive member 120 is used to drive the gripper to move along a first preset direction; wherein the movement paths of adjacent grippers are set in parallel and staggered.

[0108] In these embodiments, the drive member 120 is used to drive the gripper to move along a first preset direction, and the movement paths of adjacent grippers are parallel but staggered.

[0109] The drive unit 120 is responsible for driving the grippers to move along a first preset direction (usually the direction of wire delivery). This can be achieved by electric, pneumatic, or hydraulic means. The drive unit 120 provides precise position control, ensuring that each gripper accurately reaches its predetermined working position. The movement paths of adjacent grippers are parallel, but they are staggered. This means that when one gripper moves, it will not directly collide or interfere with adjacent grippers. By staggering, multiple grippers can be arranged more efficiently in a limited space while ensuring their independent operation.

[0110] Obviously, the parallel staggered movement path can prevent adjacent grippers from interfering with each other during movement, thereby improving the reliability and safety of the system, and ensuring that it enters the preset handover station for handover of wires.

[0111] Specific workflow;

[0112] Initial state: All grippers are in the initial position, waiting for the wire to enter.

[0113] Wire clamping: The first jaw grips one end of the wire.

[0114] Movement and handover: The drive unit 120 drives the first gripper to move along the first preset direction, feeding the wire into the wire stripping station. At this time, the second gripper can hold the other part of the wire, ready for the next operation.

[0115] Continuous operation: As the first gripper completes its task and releases the wire, the second gripper begins to move, feeding the wire into the next station (such as the bolt insertion station), while the third gripper can continue to perform subsequent operations (such as the crimping station).

[0116] Continuous cycle: This process is repeated continuously, forming a highly efficient assembly line operation. This design not only improves the flexibility and efficiency of the stranding machine's transfer device 100, but also enhances the system's stability and reliability, making it suitable for automated production lines requiring high precision and efficiency.

[0117] For example, the drive unit 120 is configured as a linear motion module. Of course, in other embodiments, it can also be configured as an electric actuator, a pneumatic cylinder, etc.

[0118] In some embodiments, the first preset direction, the second preset direction, and the third preset direction are all horizontally set, and the fourth preset direction is vertically set.

[0119] In these embodiments, the first, second, and third preset directions are all horizontally positioned, while the fourth preset direction is vertically positioned. This layout helps to clarify the function of each direction and ensures that the movement of the gripper and other components is coordinated.

[0120] The first preset direction is horizontal. This usually refers to the direction in which the wire or wire harness is fed during processing. The drive unit 120 moves the grippers in this direction to transfer the wire harness from one station to another (such as a wire stripping station, a bolt insertion station, and a crimping station).

[0121] The second preset direction is horizontally set. This usually refers to the arrangement direction of the internal structure of the sub-clamp 151. For example, multiple clamping arm assemblies 1511 are arranged side by side at intervals in the second preset direction, so that they can clamp different parts of the same wire harness at the same time.

[0122] The third preset direction is horizontally set. This usually refers to the direction of movement of the slider 1514 and the fixed clamping arm 15112. The groove 15141 on the slider 1514 extends along the third preset direction, allowing the slider 1514 to move in this direction, thereby driving the fixed clamping arm 15112 to move.

[0123] The fourth preset direction is vertical. This usually refers to the direction in which the drive module 1517 drives the slider 1514 to move. The drive end pushes the slider 1514 to move up and down in the vertical direction, and then through mechanical structures such as the guide rod 1513, the movable clamping arm 15111 rotates around the preset axis to realize the opening and closing action of the clamp.

[0124] In other words, throughout the production line, the wire is conveyed horizontally along a first preset direction and processed sequentially at different workstations. The drive unit 120 moves the gripper along this direction to ensure that the wire can be smoothly transferred from one workstation to the next.

[0125] Multiple clamping arm assemblies 1511 within the sub-clamp 151 are arranged horizontally along a second preset direction. This allows for independent control of different parts of the wire on the same plane, improving clamping stability and operational flexibility.

[0126] The slide groove 15141 of the slider 1514 extends horizontally along a third preset direction, allowing the slider 1514 to move horizontally. This may be parallel or perpendicular to the first preset direction, depending on the specific layout of the device. The movement of the slider 1514 directly affects the positional change of the fixed clamping arm 15112.

[0127] The drive end of the drive module 1517 vertically pushes the slider 1514 along a fourth preset direction. This vertical thrust is transmitted to the movable clamping arm 15111 through the guide rod 1513, causing it to rotate around a preset axis on the base, thereby realizing the opening and closing action of the clamp. This design ensures that the opening and closing action of the clamping arm is smooth and precise.

[0128] like Figure 1 As shown, in some embodiments, there are four grippers. In the first preset direction, the four grippers are a wire stripping gripper 110, a bolt threading gripper 130, a transfer gripper 140, and a crimping gripper 150. The wire stripping station is located within the movement range of the corresponding wire stripping gripper 110, the bolt threading gripper 130, and the crimping gripper 150. The wire stripping gripper 110 is connected to the driving member 120, the bolt threading gripper 130 is connected to the driving member 120, and the crimping gripper 150 is connected to the driving member 120.

[0129] The stripping jaws 110 and crimping jaws 150 are both vertically downward, while the transfer jaws 140 and bolt clamping jaws are both vertically upward.

[0130] In these embodiments, there are four grippers, and each gripper has a specific function and position setting. This configuration further optimizes the transfer device 100 of the stranding machine, enabling it to complete different processing steps more efficiently.

[0131] Wire stripping jaws 110: The wire stripping jaws 110 are located at the starting position in a first preset direction. The wire stripping jaws 110 are responsible for gripping the wire and feeding it into the wire stripping station for stripping the insulation layer. A drive unit 120 is connected, allowing it to move along the first preset direction. The clamping direction of the wire stripping jaws 110 is vertically downward, facilitating the feeding of the wire into the wire stripping mechanism.

[0132] Connector insertion jaw 130: The connector insertion jaw 130 is located after the wire stripping jaw 110 in a first preset direction. The connector insertion jaw 130 is responsible for clamping the stripped wire and feeding it into the connector insertion station for insertion of the terminal connector. The connector insertion jaw 130 is connected to a drive unit 120 and can move along the first preset direction. The clamping direction of the connector insertion jaw 130 is vertically upward, which facilitates feeding the wire into the connector insertion mechanism.

[0133] Intermediate clamp 140: The intermediate clamp 140 is located after the threading clamp 130 in a first preset direction. As an intermediate transition clamp, the intermediate clamp 140 is responsible for receiving the wire from the threading clamp 130 and transferring it to the crimping clamp 150. There is no connecting drive 120, but it is usually provided to ensure accurate movement to the predetermined position. The clamping direction of the intermediate clamp 140: It is vertically upward to facilitate receiving the wire from the intermediate clamp 140.

[0134] Crimping jaw 150: The crimping jaw 150 is located after the intermediate jaw 140 in a first preset direction. The crimping jaw 150 is responsible for clamping and feeding the wires that have undergone the bolt insertion process into the crimping station to crimp and fix the terminal connector. The crimping jaw 150 is connected to a drive unit 120 and can move along the first preset direction. The clamping direction of the crimping jaw 150 is vertically downward, which facilitates feeding the wires into the crimping mechanism.

[0135] Clearly, each gripper has a specific function, making the entire processing more organized and efficient. Using specialized grippers to handle different processes reduces the complexity of individual grippers, improving system reliability and maintainability. Four grippers, each responsible for a different process, form a highly efficient assembly line system. Wires can be smoothly transferred between different grippers, reducing waiting time and handling frequency. The stripping gripper 110 and crimping gripper 150 have their jaws facing downwards, while the transfer gripper 140 and bolt insertion gripper 130 have their jaws facing upwards. This design reduces interference between grippers, ensuring the independence and accuracy of each process. Through the coordinated work of multiple grippers, multi-task parallel processing can be achieved, significantly improving production efficiency. Downtime caused by changing fixtures or adjusting gripper positions is reduced. Because each gripper has a defined function and movement path, the control system can more easily manage the movements of each gripper, reducing the complexity of programming and debugging.

[0136] Specific workflow:

[0137] 1. Initial state: All grippers are in the initial position, waiting for the wire to enter.

[0138] 2. Operation of stripping jaw 110: The stripping jaw 110 clamps the wire and sends it into the stripping station to strip the insulation layer.

[0139] 3. Bolt insertion clamp 130 action: The stripped wire is clamped by the bolt insertion clamp 130 and sent into the bolt insertion station for insertion of the terminal connector.

[0140] 4. Transfer gripper 140 action: The threaded wire is gripped by the transfer gripper 140 and is ready to be transferred to the next gripper.

[0141] 5. Crimping jaw 150 operation: The transfer jaw 140 transmits the wire to the crimping jaw 150, which then sends it into the crimping station to crimp and fix the terminal connector.

[0142] 6. Repeated cycle: After completing the above steps, each gripper returns to its initial position, ready to process the next wire, forming a continuous processing flow.

[0143] This configuration not only improves the production efficiency of the stranding machine, but also enhances the stability and reliability of the system, making it suitable for automated production lines that require high precision and high efficiency.

[0144] In some embodiments, the grippers corresponding to the bolt threading station and the crimping station respectively further include a wire support portion 152. The wire support portion 152 extends along the first preset direction and is connected to the slider 1514. The top of the wire support portion 152 can abut against the lower side of the wire harness.

[0145] In these embodiments, the grippers corresponding to the threading and crimping stations also include a wire support portion 152. This design further enhances the grippers' control and support of the wires, ensuring stability and accuracy during the processing.

[0146] The wire support portion 152 extends along a first preset direction (typically the direction of wire delivery). The wire support portion 152 is connected to the slider 1514. This means that the wire support portion 152 moves as the slider 1514 moves. The top of the wire support portion 152 can abut against the underside of the wire harness, providing additional support and preventing the wire from sagging or shifting during processing.

[0147] Clearly, the wire support 152 provides stable support by contacting the lower side of the wire harness, reducing the swaying and shifting of the wires during processing.

[0148] For example, the upper side of the wire support portion 152 is a support surface, and the height of both ends of the support surface gradually decreases in the direction near the end.

[0149] like Figure 9 As shown, in some embodiments, this application also provides a stranding machine, which includes a transfer device 100 as described in any of the above embodiments.

[0150] Since the aforementioned transfer device 100 has the above-mentioned technical effects, the stranding machine including the transfer device 100 should have the same technical effects, which will not be elaborated here.
