[0048] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0051] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0053] In the related art, the transfer device of the wire twisting machine clamps the wire by moving the clamping claw, and then passes the wire to the wire twisting mechanism for the wire twisting process after the wire stripping mechanism performs the wire stripping process, the bolt threading mechanism performs the bolt threading process, and the crimping mechanism performs the crimping process. However, this method has many transfer processes, is time-consuming, and has low work efficiency.

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a transfer device 100, which includes a plurality of the above-mentioned jaws and a plurality of driving members 120, wherein the plurality of jaws are arranged in sequence in a first preset direction, and the jaws are used to clamp the wire harness; at least one of the adjacent jaws is connected to the driving member 120, and the plurality of driving members 120 are respectively used to drive the corresponding jaws to move, so that the adjacent jaws can approach or move away from each other in the first preset direction, and any adjacent jaws can approach each other so that a preset handover station is formed between the two, and the adjacent jaws located at the preset handover station can respectively clamp different parts of the same wire harness; wherein, the transfer device 100 is configured with a wire stripping station, a bolting station and a crimping station, and the wire stripping station, the bolting station and the crimping station are arranged at intervals in the first preset direction, and the wire stripping station, the bolting station and the crimping station are respectively located within the moving range of the corresponding jaws.

[0055] In these embodiments, the technical solution provided by the present application is intended to optimize the transfer device 100 of the stranding machine to improve production efficiency. Specifically, first, multiple jaws work together, that is, a design is adopted in which multiple jaws are arranged in sequence in a first preset direction, and these jaws can move independently but 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., a wire harness) from one process to another.

[0056] For example, in this embodiment, the clamping jaws are parallel clamping jaws. Of course, in other embodiments, the clamping jaws are configured as swinging clamping jaws, which are not specifically limited here, as long as the wire harness can be clamped.

[0057] Secondly, precise control supported by the drive member 120, each or each pair of adjacent jaws is connected to at least one drive member 120, which enables the jaws to move relative to each other in a first preset direction, i.e., closer or farther away. Obviously, this allows the position of the jaws to be adjusted as needed to create specific working areas, such as stripping stations, bolting stations, and crimping stations. In addition, by ensuring that any two adjacent jaws can cooperate with each other to clamp different parts of the same wire, thereby forming an effective intersection and realizing transfer between adjacent jaws, the processing speed and accuracy are further improved.

[0058] Exemplarily, the driving member 120 includes a first driving module 1517 and a second driving module 1517, the first driving module 1517 is connected to the clamp, the first driving module 1517 is used to drive the clamp to move vertically, the second driving module 1517 is connected to the first driving module 1517, the second driving module 1517 is used to drive the clamp to move along a first preset direction, the first preset direction is a horizontal straight line direction, and thus the adjacent clamps can avoid and dock by setting the moving range of the clamp.

[0059] Furthermore, the key process steps such as wire stripping, bolting and crimping are distributed along the same straight line and included in the range of the clamping jaws, which means that the entire processing process can be completed without changing the overall equipment layout, greatly simplifying the operation process. At the same time, since each station is within the reach of the corresponding clamping jaws, there is no need for extra time to switch stations, which significantly improves work efficiency.

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

[0061] The wire stripping station removes the insulation layer at one or both ends of the wire to expose the metal conductor inside. Mechanical blades or thermal strippers are usually used to cut and strip the insulation material. For different types of wires (such as single-core or multi-core). Exemplarily, the wire stripping station is provided with a wire stripping device to be able to strip the wire bundle transported by the clamping jaws.

[0062] At the bolting station, the bare wires are inserted into the pre-prepared terminal connectors (usually metal parts with holes). The clamps will accurately feed the stripped wires into the holes of the terminal connectors. This process involves precise positioning and proper force control to ensure that the wires are completely passed through without damage. Good bolting can ensure the safety and reliability of the electrical connection, while also ensuring that the connection has sufficient mechanical strength. Exemplarily, the bolting station is provided with a bolting device, which can perform bolting operations on the wire harnesses that are transported by the clamps and stripped.

[0063] The crimping station is responsible for fixing the wires inserted into the connector and tightly combining the connector and the wires by applying pressure. Use a special crimping tool or mold to compress the connector under a certain pressure so that the metal part inside the connector can firmly wrap the wires. This not only enhances the electrical contact performance, but also improves the waterproof and dustproof capabilities. Effective crimping not only provides a stable electrical connection, but also increases the durability of the entire assembly and reduces the possible failure rate in the future. Exemplarily, the crimping station is provided with a crimping device that can perform crimping operations on the wire harness that has been transported by the clamping jaws and bolted.

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

[0065] In some embodiments, the clamp includes a sub-jaw 151 having a connecting end and multiple clamping ends, the multiple clamping ends are arranged at intervals in a second preset direction, the multiple clamping ends can respectively clamp different parts of the same wire harness, and the connecting end is connected to the driving member 120.

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

[0067] The plurality of clamping ends are located in the 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 the plurality of clamping ends act on different positions of a wire harness at the same time, the wire harness can be more firmly fixed, and shaking or displacement during processing can be reduced, thereby improving process accuracy and facilitating the handover of the wire harness between adjacent clamping jaws.

[0068] In other words, achieving multi-point clamping in one clamp can simplify the transfer process from one station to another to a certain extent, because there is no need to completely release the wire harness and then re-clamp it, only the position of the clamping end needs to be adjusted. Since the number of times the wire harness needs to be re-clamped is reduced, the entire production process becomes more continuous and smooth, thereby improving overall work efficiency. In addition, the design of this sub-jaw 151 can better meet the needs of the wire stripping station, bolting station and crimping station, ensuring that each step of the process can be completed efficiently and accurately. This multi-point clamping structure is particularly useful for situations where different parts of the wire need to be processed at the same time.

[0069] Exemplarily, in the present embodiment, the number of the clamping ends is two. Of course, in other embodiments, the number of the clamping ends may also be three, four, five, six, etc.

[0070] like Figure 3 and Figure 4 As shown, in some embodiments, the sub-clamping jaw 151 includes a plurality of clamping arm groups 1511 and a power unit, the plurality of clamping arm groups 1511 are arranged side by side at intervals in a second preset direction, the clamping arm group 1511 includes two clamping arms, and a clamping opening is formed between the two clamping arms of the same clamping arm group 1511; the power unit has a driving end and a fixed end, the driving end is connected to the clamping arm, the driving end can drive the two clamping arms of the same clamping arm group 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-clamping jaw 151 is further refined, and the sub-clamping jaw includes a plurality of clamping arm groups 1511 and a power unit. This design can provide more refined control and wider adaptability, and each clamping arm group 1511 includes two clamping arms. A clamping opening is formed between the two clamping arms for clamping the wiring harness. A plurality of such clamping arm groups 1511 are arranged side by side at intervals in the second preset direction, which means that they can be arranged along the length direction of the wire to form a plurality of clamping ends, thereby clamping different parts of the wire.

[0072] For example, in this embodiment, the number of the clamping arm groups 1511 is two. Of course, in other embodiments, the number of the clamping arm groups 1511 is three, four, five, and so on.

[0073] The power unit is connected to the clamping arms in each clamping arm group 1511, and can drive the two clamping arms to move closer to or away from each other. The power unit is connected to the driving member 120 to ensure that the entire power unit can be stably installed and controlled. When it is necessary to clamp the wire, the power unit makes the two clamping arms in the same clamping arm group 1511 move closer to each other, thereby closing the clamp and firmly clamping the wire. Conversely, when it is necessary to release the wire or move the wire to the next workstation, the power unit will move the clamping arms away from each other, open the clamp, and release the wire. Since the multiple clamping arm groups 1511 are arranged along the second preset direction, this allows different parts of the same wire to be independently controlled, thereby enhancing the flexibility and accuracy of the operation.

[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 the clamping arms, and the opening and closing action between the pair of clamping arms is achieved 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 limit block 1520, a limit pin 1519, a telescopic spring 1522 and a driving module 1517, the base has a preset axis, the preset axis is arranged parallel to the second preset direction, the two clamping arms of the same clamping arm group 1511 are respectively a fixed clamping arm 15112 and a movable clamping arm 15111, the movable clamping arm 15111 is hinged to the base, and the movable clamping arm 15111 can rotate around the preset axis to make 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 is extended along an arc direction, the axis of the guide groove 15151 coincides with the preset axis, and the plane where the arc direction is located is perpendicular to the second preset direction;

[0077] The slider 1514 has a slide groove 15141, and the slide groove 15141 is extended along the third preset direction;

[0078] The guide rod 1513 has an axis, and the axis of the guide rod 1513 is arranged parallel to the preset axis. The fixed clamping arm 15112 has a toggle slot 1512, and the toggle slot 1512 is extended along the third preset direction. The guide rod 1513 is arranged on the movable clamping arm 15111, and one end of the guide rod 1513 is movably inserted into the slide slot 15141, and the other end of the guide rod 1513 is movably inserted into the toggle slot 1512, and at least the portion of the guide rod 1513 located in the slide slot 15141 and the toggle slot 1512 is cylindrical; wherein the width of the toggle slot 1512 is greater than the outer diameter of the portion of the guide rod 1513 located in the toggle slot 1512;

[0079] The slide rail 1523 is disposed on the base, and the slide rail 1523 is extended along a fourth preset direction, and the fixed clamping arm 15112 is slidably connected to the slide rail 1523;

[0080] The limiting block 1520 is disposed on the base, and the limiting block 1520 has a limiting groove 1521, and the limiting groove 1521 is extended along the fourth preset direction;

[0081] The limiting pin 1519 is slidably disposed in 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 a fourth preset direction to move away from the base.

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

[0084] In these embodiments, the power unit is a complex mechanical structure used to control the opening and closing of the clamping arm set 1511. The following is a detailed description of the components of the 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 rotation around the preset axis, thereby achieving the movement of approaching or moving away from the fixed clamping arm 15112.

[0086] Exemplarily, the movable clamping arm 15111 has a hinge hole 1518, and the base is provided with a rotating shaft 1516, and the rotating shaft 1516 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 along an arc-shaped 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 where the arc-shaped direction is located is perpendicular to the second preset direction, ensuring that the rotational movement of the movable clamping arm 15111 will not be affected by other directions.

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

[0089] Guide rod 1513 and toggle slot 1512: The guide rod 1513 located in the slide slot 15141 and the toggle slot 1512 is cylindrical, ensuring good sliding performance. The toggle slot 1512 is wider than the outer diameter of the guide rod 1513, allowing a certain degree of relative displacement, and also helping to adapt to different clamping requirements. The axis of the guide rod 1513 is parallel to the preset axis on the base, which allows the guide rod 1513 to slide smoothly in the slide slot 15141 without generating additional friction or interference.

[0090] Exemplarily, the guide rod 1513 is configured as a cylinder. Optionally, the guide rod 1513 and the movable clamping arm 15111 are configured as an integrated whole.

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

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

[0093] Limit block 1520 and limit pin 1519: The limit slot 1521 on the limit block 1520 and the limit pin 1519 are used in combination to limit the maximum stroke of the fixed clamping arm 15112 to prevent it from exceeding the safety range. This not only increases the safety of the system, but also ensures the accuracy of the clamping action.

[0094] 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, applying a driving force to the fixed clamping arm 15112 to enable 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 automatically reset even when there is no external force.

[0095] For example, in the present application, the slide rail 1523 extends vertically, and in the absence of external force, the telescopic spring 1522 drives the fixed clamping arm 15112 to rise.

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

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

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

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

[0100] Taking the slide rail 1523 extending vertically as an example, when the driving module 1517 starts to work, the driving module 1517 will push the slider 1514 to move along the fourth preset direction. Since the slider 1514 is connected to the guide rod 1513, and the guide rod 1513 passes through the toggle slot 1512 on the fixed clamping arm 15112, the movement of the slider 1514 and the elastic force of the telescopic spring 1522 to restore the deformation will indirectly drive the fixed clamping arm 15112 to slide along the slide rail 1523 until the limit pin 1519 reaches the end above the limit slot 1521, and the fixed clamping arm 15112 stops. At the same time, due to the large gap between the toggle slot 1512 and the guide rod 1513, the movable clamping arm 15111 will continue to rise. Furthermore, since the movable clamping arm 15111 is hinged to the base and the guide rod 1513 is also installed on the movable clamping arm 15111, the movement of the slider 1514 will also cause the movable clamping arm 15111 to rotate around the preset axis, and finally realize the closing action between the two arms in the clamping arm group 1511, that is, the fixed clamping arm 15112 and the movable clamping arm 15111 are first raised and then clamped. 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 in the absence of external force. Throughout the process, the limit system ensures that all movements are carried out within a safe range, avoiding the risks caused by excessive movement.

[0101] And, the opening process is as follows: also because there is a very large gap between the guide rod 1513 and the toggle slot 1512, the movable clamping arm 15111 moves downward first, and the clamping jaw opens to 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 toggle slot 1512, driving the fixed clamping arm 15112 to move downward, and the clamping jaw completes the opening action, that is, the clamping jaw opens first and then descends.

[0102] like Figure 7 As shown, in some embodiments, the number of sub-jaws 151 is two, the clamp has a preset plane, the two sub-jaws 151 are symmetrically arranged about the preset plane, and the preset plane is perpendicular to the first preset direction.

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

[0104] The clamp has a preset plane, which is a reference plane in the design. The two sub-jaws 151 are symmetrically arranged about the preset plane. This means that the structures on both sides of the preset plane should be mirror-symmetrical. The preset plane is perpendicular to the first preset direction (usually the direction of wire movement). The symmetrical design ensures that the force on both sides is uniform during the clamping process, reducing the deviation or damage of the wire caused by uneven force on one side. This uniform clamping force can improve the processing accuracy and quality.

[0105] Because of the 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 more convenient because only one set of standard parts is required.

[0106] The symmetrical twin sub-jaws 151 can clamp a pair of wires at the same time, further improving work efficiency. In addition, since the fixed clamping arms 15112 of the two sub-jaws 151 are close to each other, they can be integrated. In addition, the fixed clamping arms 15112 are arranged between the movable clamping arms 15111, which can reduce the size of the clamps and the distance between the pair of wires.

[0107] like Figure 3 As shown, in some embodiments, the driving member 120 is used to drive the clamping jaws to move along a first preset direction; wherein the moving paths of adjacent clamping jaws are arranged in parallel and staggered.

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

[0109] The driving member 120 is responsible for driving the jaws to move along a first preset direction (usually the direction of wire conveying). This can be achieved by electric, pneumatic or hydraulic means. The driving member 120 can provide precise position control to ensure that each jaw can accurately reach the predetermined working position. The moving paths of adjacent jaws are parallel, but there is a certain offset between them. This means that when a jaw moves, it will not directly collide or interfere with the adjacent jaws. Through the offset setting, multiple jaws can be arranged more efficiently in a limited space while ensuring their independent operability.

[0110] Obviously, the parallel staggered moving path can prevent adjacent jaws from interfering with each other during the movement, thereby improving the reliability and safety of the system, and ensuring access to the preset handover station to hand over the wires.

[0111] Specific workflow;

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

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

[0114] Movement and handover: The driving member 120 drives the first clamping jaw to move along the first preset direction to send the wire into the wire stripping station. At this time, the second clamping jaw can clamp another part of the wire and prepare 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 to the next station (such as the threading station), while the third gripper can continue with the subsequent operation (such as the crimping station).

[0116] Cycle and repeat: This process is repeated continuously, forming an efficient assembly line operation. This design not only improves the flexibility and efficiency of the transfer device 100 of the stranding machine, but also enhances the stability and reliability of the system, and is suitable for automated production lines that require high precision and high efficiency.

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

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

[0119] In these embodiments, the first preset direction, the second preset direction and the third preset direction are all arranged horizontally, while the fourth preset direction is arranged vertically. This layout helps to clarify the role of each direction and ensure the coordinated movement of the clamp and other components.

[0120] The first preset direction is set horizontally. It usually refers to the conveying direction of the wire or wire harness during the processing. The driving member 120 moves the clamping jaws along this direction to transfer the wire harness from one station to another station (such as the stripping station, the bolting station and the crimping station).

[0121] The second preset direction is arranged horizontally, which generally refers to the arrangement direction of the internal structure of the sub-clamping jaws 151. For example, a plurality of clamping arm groups 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 arranged, which generally refers to the moving direction of the slider 1514 and the fixed clamping arm 15112. The slide slot 15141 on the slider 1514 extends along the third preset direction, allowing the slider 1514 to move in the direction, thereby driving the fixed clamping arm 15112 to move.

[0123] The fourth preset direction is set vertically. It usually refers to the moving direction of the slider 1514 driven by the driving module 1517. The driving end pushes the slider 1514 to move up and down in the vertical direction, and then the movable clamping arm 15111 rotates around the preset axis through the mechanical structure such as the guide rod 1513 to realize the opening and closing action of the clamp.

[0124] In other words, in the entire production line, the wire is transported horizontally along the first preset direction and processed in different stations in sequence. The driving member 120 moves the clamping jaws along this direction to ensure that the wire can be smoothly transferred from one station to the next station.

[0125] The plurality of clamping arm groups 1511 in the sub-clamping jaws 151 are arranged horizontally along the second preset direction, so that different parts of the wire can be independently controlled on the same plane, thereby improving the clamping stability and the flexibility of operation.

[0126] The slide slot 15141 of the slider 1514 extends horizontally along the third preset direction, so that the slider 1514 can move in the horizontal direction. 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 position change of the fixed clamping arm 15112.

[0127] The driving end of the driving module 1517 vertically pushes the slider 1514 along the fourth preset direction. The vertical thrust is transmitted to the movable clamping arm 15111 through the guide rod 1513, so that the movable clamping arm 15111 rotates around the preset axis on the base, thereby realizing the opening and closing action of the clamping jaw. This design ensures that the opening and closing action of the clamping arm is smooth and accurate.

[0128] like Figure 1 As shown, in some embodiments, the number of the clamping jaws is four. In the first preset direction, the four clamping jaws are respectively a wire stripping clamping jaw 110, a bolting clamping jaw 130, a transfer clamping jaw 140 and a crimping clamping jaw 150. The wire stripping station is located within the corresponding moving range of the wire stripping clamping jaw 110, the bolting clamping jaw 130 is located within the corresponding moving range of the bolting clamping jaw 130, and the crimping clamping jaw 150 is located within the corresponding moving range of the crimping clamping jaw 150. The wire stripping clamping jaw 110 is connected to the driving member 120, the bolting clamping jaw 130 is connected to the driving member 120, and the crimping clamping jaw 150 is connected to the driving member 120.

[0129] Among them, the clamping openings of the wire stripping clamp 110 and the crimping clamp 150 are both arranged vertically downward, and the clamping openings of the transfer clamp 140 and the bolt-threading transport clamp assembly are both arranged vertically upward.

[0130] In these embodiments, the number of the clamping jaws is four, and each clamping jaw 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 jaw 110: The wire stripping jaw 110 is located at the starting position in the first preset direction. The wire stripping jaw 110 is responsible for clamping the wire and sending it to the wire stripping station to strip the insulation layer. It is connected to a driving member 120 and can move along the first preset direction. The clamping direction of the wire stripping jaw 110: It is set vertically downward to facilitate the wire to be fed into the wire stripping mechanism.

[0132] Bolting jaw 130: Bolting jaw 130 is located behind wire stripping jaw 110 in the first preset direction. Bolting jaw 130 is responsible for clamping the stripped wire and feeding it into the bolting station for inserting the terminal connector. Bolting jaw 130 is connected to driving member 120 and can move along the first preset direction. Clamping direction of bolting jaw 130: vertically upward, which is convenient for feeding the wire into the bolting mechanism.

[0133] Transfer jaw 140: The transfer jaw 140 is located behind the bolting jaw 130 in the first preset direction. As an intermediate transition jaw, the transfer jaw 140 is responsible for receiving the wire from the bolting jaw 130 and transferring it to the crimping jaw 150. There is no drive member 120 connected, but a drive member 120 is usually provided to ensure that it can accurately move to the predetermined position. The clamping direction of the transfer jaw 140: It is set vertically upward to facilitate receiving the wire from the transfer jaw 140.

[0134] Crimping jaw 150: The crimping jaw 150 is located behind the transfer jaw 140 in the first preset direction. The crimping jaw 150 is responsible for clamping the wire that has been bolted and feeding it into the crimping station to crimp and fix the terminal connector. The crimping jaw 150 is connected to the driving member 120 and can move along the first preset direction. The clamping direction of the crimping jaw 150: It is set vertically downward to facilitate the feeding of the wire into the crimping mechanism.

[0135] Obviously, each jaw has a specific function, making the entire processing process more orderly and efficient. By using specialized jaws to handle different processes, the complexity of a single jaw is reduced, and the reliability and maintainability of the system are improved. The four jaws are responsible for different processes, forming an efficient assembly line operation system. The wire can be smoothly transferred between different jaws, reducing waiting time and the number of handling times. The jaws of the stripping jaw 110 and the crimping jaw 150 are facing downward, while the jaws of the transfer jaw 140 and the bolting jaw 130 are facing upward. This design reduces the mutual interference between the jaws and ensures the independence and accuracy of each process. Through the collaborative work of multiple jaws, multi-task parallel processing can be achieved, which significantly improves production efficiency. The downtime caused by changing the fixture or adjusting the position of the jaws is reduced. Since each jaw has a clear function and motion path, the control system can more easily manage the actions of each jaw, reducing the complexity of programming and debugging.

[0136] Specific workflow:

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

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

[0139] 3. Action of the plugging jaws 130: The stripped wire is clamped by the plugging jaws 130 and sent to the plugging station for insertion of the terminal connector.

[0140] 4. The transfer clamp 140 moves: the threaded wire is clamped by the transfer clamp 140 and is ready to be transferred to the next clamp.

[0141] 5. The crimping jaw 150 moves: the transfer jaw 140 transfers the wire to the crimping jaw 150, and the crimping jaw 150 sends it to the crimping station for crimping and fixing the terminal connector.

[0142] 6. Reciprocating: 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, and is suitable for automated production lines that require high precision and high efficiency.

[0144] In some embodiments, the clamps corresponding to the bolting station and the crimping station also include a wire supporting portion 152, respectively. The wire supporting portion 152 is extended along the first preset direction, and the wire supporting portion 152 is connected to the slider 1514. The top of the wire supporting portion 152 can abut against the lower side of the wiring harness.

[0145] In these embodiments, the clamping jaws corresponding to the bolting station and the crimping station further include a wire supporting portion 152. This design further enhances the control and support of the wire by the clamping jaws, ensuring stability and accuracy during processing.

[0146] The wire support portion 152 extends along a first preset direction (usually the direction in which the wire is transported). The wire support portion 152 is connected to the slider 1514. This means that the wire support portion 152 moves with the movement of the slider 1514. The top of the wire support portion 152 can abut against the bottom side of the wire harness to provide additional support to prevent the wire from sagging or shifting during processing.

[0147] Obviously, the wire supporting portion 152 provides stable support by contacting the lower side of the wire harness, thereby reducing the shaking and deviation of the wire during processing.

[0148] Illustratively, the upper side of the wire supporting portion 152 is a supporting surface, and the heights of both ends of the supporting surface gradually decrease in a direction approaching the end.

[0149] like Fig. 9 As shown, in some embodiments, the present application also provides a wire twisting machine, which includes a transfer device 100 as described in any one of the above embodiments.

[0150] Since the above-mentioned 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 repeated here.

[0151] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0152] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0153] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
