Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] Please see Figures 1 to 8 This embodiment provides a stranding machine, which includes a frame 10, a first conveying mechanism 20, a lifting mechanism 30, a wire clamping mechanism 40, a translation mechanism 50, and a stranding mechanism 60.

[0026] The frame 10 serves as the supporting foundation for the entire machine and has a tabletop structure. Adjustable feet can be installed at the bottom to keep the equipment level. A work surface is provided on top of the frame 10 for the installation of various mechanisms.

[0027] The first conveying mechanism 20 is mounted on the worktable of the frame 10 and is used to convey materials to be twisted, such as wires, wire harnesses, etc. Specifically, the first conveying mechanism 20 includes a first conveyor belt 21 and a wire carrier 22. The first conveyor belt 21 is driven by a motor to rotate cyclically. The wire carrier 22 is fixedly connected to the surface of the first conveyor belt 21 by bolts or clips and can move along the conveying direction with the first conveyor belt 21.

[0028] Furthermore, the wire carrier 22 includes a mounting base 221, with bearing portions 222 extending upward from both ends of the mounting base 221. A wire-carrying groove 223 is formed in the middle of the bearing portion 222. In use, the two bearing positions on the wire to be twisted are respectively inserted into the corresponding wire-carrying grooves 223, with the middle section between the two bearing positions suspended to facilitate subsequent clamping. The selection of the bearing positions can be determined according to the actual wire and the wire carrier. For example, the two bearing positions can be respectively set on both sides of the midpoint of the wire, with the distance between the two bearing positions and the midpoint of the wire being 1 / 2 the length of the wire carrier.

[0029] The lifting mechanism 30 is mounted on the frame 10 and located above the first conveying mechanism 20. Specifically, the lifting mechanism 30 can adopt a structure of servo motor with lead screw module or cylinder with guide column and guide sleeve, and its function is to provide linear reciprocating motion in the vertical direction.

[0030] The wire clamping mechanism 40 is installed on the moving end of the lifting mechanism 30 and can move up and down with the lifting mechanism 30. The wire clamping mechanism 40 is used to clamp materials from the wire carrier 22 of the first conveying mechanism 20 and lift the materials to the stranding station.

[0031] Specifically, the wire clamping mechanism 40 includes a plurality of wire clamping assemblies 41. Preferably, three wire clamping assemblies 41 are provided to perform the stranding of three sets of wires simultaneously. Each wire clamping assembly 41 includes a wire clamping drive device 411 and a wire clamping actuator 412.

[0032] The wire clamping actuator 412 includes a first clamping plate 4121 and a second clamping plate 4122 disposed opposite to each other. The wire clamping drive device 411 is connected to the first clamping plate 4121 and the second clamping plate 4122 respectively to drive the first clamping plate 4121 and the second clamping plate 4122 to move closer or further apart from each other, so as to clamp or release the wire.

[0033] As a preferred driving structure, the wire clamping drive device 411 includes two wire clamping drive components 411a, which are respectively disposed at the upper and lower ends of the wire clamping actuator 412. This design of synchronous driving at both ends ensures that the long strip-shaped first clamping plate 4121 and second clamping plate 4122 are subjected to uniform force during opening and closing, avoiding clamping skew or insufficient clamping force due to unilateral force.

[0034] Referring further to the internal structure, each wire clamping drive component 411a includes a wire clamping drive unit 4111, a wire clamping support 4112, a first pusher 4113, a first lead screw 4114, a first connecting rod 4115, a second connecting rod 4116, a third connecting rod 4117, and a fourth connecting rod 4118. Preferably, the wire clamping drive unit 4111 can be a servo motor.

[0035] The first pusher 4113 is slidably disposed in the guide groove of the wire clamping support 4112 and is threadedly connected to the first lead screw 4114. The first lead screw 4114 is drively connected to the output shaft of the wire clamping drive unit 4111. When the wire clamping drive unit 4111 rotates, it drives the first lead screw 4114 to rotate, thereby driving the first pusher 4113 to move axially.

[0036] One end of the first connecting rod 4115 is hinged to the first pusher 4113, and the other end is hinged to one end of the third connecting rod 4117. The middle part or the other end of the third connecting rod 4117 is hinged to the wire clamping support 4112, and a first push rod 4119 is integrally formed or fixedly connected to the third connecting rod 4117, which is fixedly connected to the first clamping plate 4121.

[0037] One end of the second connecting rod 4116 is hinged to the first pushing member 4113, and the other end is hinged to one end of the fourth connecting rod 4118. The middle part or the other end of the fourth connecting rod 4118 is hinged to the wire clamping support 4112, and a second pushing rod 4110 is integrally formed or fixedly connected to the fourth connecting rod 4118, which is fixedly connected to the second clamping plate 4122.

[0038] Through the aforementioned linkage mechanism, when the first pusher 4113 is driven to move by the lead screw, the first link 4115 and the second link 4116 pull the third link 4117 and the fourth link 4118 to rotate around the hinge point, thereby driving the first pusher 4119 and the second pusher 4110 to move towards or away from each other, thus realizing the smooth opening and closing of the first clamping plate 4121 and the second clamping plate 4122.

[0039] The translation mechanism 50 is mounted on the frame 10, and its direction of movement intersects the conveying direction of the first conveying mechanism, preferably perpendicularly. The translation mechanism 50 is used to drive the stranding mechanism 60 to approach or move away from the clamping mechanism 40. By driving the stranding mechanism 60 to approach the clamping mechanism 40, it can grasp the wire clamped by the clamping mechanism 40. By driving the stranding mechanism 60 to move away from the clamping mechanism 40, it can pull apart the wire to be stranded, so that it is in a suitable state to be stranded, that is, both ends of the wire are fixed by the clamping mechanism 40 and the stranding mechanism 60 respectively, and the main body of the wire is stretched.

[0040] The stranding mechanism 60 is mounted on the translation mechanism 50 and can move horizontally with the translation mechanism 50. The stranding mechanism 60 and the clamping mechanism 40 are arranged opposite each other in space, so that the stranding mechanism 60 and the clamping mechanism 40 can work together to stretch and rotate the wire.

[0041] The stranding mechanism 60 includes a gripping component 61 for gripping material and a rotary drive component 62 for driving the gripping component 61 to rotate. The gripping component 61 and the rotary drive component 62 are connected in a driving connection.

[0042] The gripping assembly 61 includes a gripping drive unit 611, a second pusher 612, a second lead screw 613, a push rod 614, a gripping sleeve 615, a fifth link 616, a sixth link 617, and a gripper. The gripper specifically includes a first claw 618 and a second claw 619.

[0043] The gripping drive unit 611 is connected to the second lead screw 613 for driving the second lead screw 613 to rotate. The second lead screw 613 is threadedly connected to the second pusher 612. The rear end of the push rod 614 is connected to the second pusher 612, and the front end of the push rod 614 is slidably sleeved in the internal through hole of the gripping sleeve 615. The gripping drive unit 611 can be a servo motor.

[0044] One end of the fifth link 616 is hinged to the front end of the push rod 614, and the other end is hinged to the rear end of the first claw 618. One end of the sixth link 617 is hinged to the front end of the push rod 614, and the other end is hinged to the rear end of the second claw 619. The middle part of the first claw 618 and the middle part of the second claw 619 are hinged to each other, and the hinge axis is also hinged to the front extension arm of the gripping sleeve 615.

[0045] When the gripping drive unit 611 drives the second lead screw 613 to rotate, the second pusher 612 drives the push rod 614 to extend and retract within the gripping sleeve 615. When the push rod 614 pushes forward, it pushes the rear ends of the first claw 618 and the second claw 619 to open through the fifth link 616 and the sixth link 617. According to the lever principle, the front ends of the first claw 618 and the second claw 619 close, gripping the end of the wire; conversely, when the push rod 614 is pulled back, the front end of the gripper opens.

[0046] The rotary drive assembly 62 includes a rotary drive unit 621, a first gear 622, and a second gear 623. The first gear 622 is located at the output end of the rotary drive unit 621. The second gear 623 is fixedly connected to the outer circumferential surface of the gripping sleeve 615. The first gear 622 and the second gear 623 are connected by a toothed belt drive. When the rotary drive unit 621 rotates, the first gear 622 and the toothed belt drive the second gear 623 to rotate, thereby driving the entire gripping sleeve 615 and the gripped wire to rotate at high speed around the axial direction, realizing the wire stranding function. The rotary drive unit 621 can be a servo motor.

[0047] As a preferred extension, to improve production efficiency, multiple gripping components 61 can be provided, preferably three, arranged in a straight line. Each gripping component 61 has a second gear 623 fixedly mounted on its gripping sleeve 615. Multiple second gears 623 are sequentially wound and driven together by a toothed belt, and one of the second gears 623 is connected to the first gear 622 via a toothed belt drive. In this way, only one rotary drive unit 621 is needed to drive multiple gripping components 61 to rotate synchronously, ensuring the consistency of the twisting torque and speed of multiple wires. It should be noted that, to avoid obstruction, and because those skilled in the art can unambiguously determine the position and connection relationship of the toothed belt based on the gear positions and the above description, the toothed belt is not shown in the accompanying drawings.

[0048] Furthermore, as a preferred embodiment, the stranding mechanism 60 also includes a push plate 63. The second pusher 612 in each gripping assembly 61 is fixedly connected to the push plate 63, and only one of the gripping assemblies 61 is equipped with a gripping drive unit 611. The gripping drive unit 611 is drively connected to the corresponding second pusher 612 to drive the second pusher 612 to move axially. When the second pusher 612 moves, it drives the push plate 63 to move synchronously, which in turn drives the second pushers 612 in the remaining gripping assemblies 61 to move together, thereby achieving synchronous opening and closing of multiple gripping assemblies 61. This structural design utilizes a single drive source to achieve the linkage control of multi-station gripping assemblies, effectively reducing the number of drive units, simplifying the equipment structure, and ensuring the consistency of the actions of each gripping station.

[0049] In addition, the stranding machine also includes a second conveying mechanism 70. The second conveying mechanism 70 is located below the gripping assembly 61 and is used to convey the stranded material. The conveying direction of the second conveying mechanism 70 is opposite to that of the first conveying mechanism. When the stranding operation is completed, both the clamping mechanism 40 and the gripping assembly 61 are released, and the finished wire bundle falls onto the second conveying mechanism 70 and is conveyed in the opposite direction to the unloading station.

[0050] Brief description of the work process Initially, the wire is placed on the wire carrier 22 and moves with the first conveyor belt 21 to below the wire clamping station. The lifting mechanism 30 drives the wire clamping mechanism 40 to descend, and the wire clamping drive device 411 drives the first clamping plate 4121 and the second clamping plate 4122 to close and clamp the wire. The wire is clamped between the two bearing positions. The lifting mechanism 30 rises to lift the wire and remove it from the carrier.

[0051] Subsequently, the translation mechanism 50 drives the stranding mechanism 60 to move towards the clamping mechanism 40 until the gripper of the gripping component 61 aligns with the wire. The gripping drive unit 611 actuates to drive the gripper to close and grasp the wire. Next, the translation mechanism 50 drives the stranding mechanism 60 to move away from the clamping mechanism 40 to stretch the wire. After stretching, the clamping mechanism and the gripping mechanism fix the two ends of the wire, respectively. The rotation drive component 62 is activated, driving the gripping sleeve 615 to rotate at high speed to strand the wire. The wire has ends to limit movement during the stretching process, preventing the wire from detaching from the clamping mechanism 40 or the stranding mechanism 60.

[0052] After the twisting is completed, the clamping mechanism 40 is released, the gripping component 61 is also released, the finished product falls onto the second conveying mechanism 70 and is sent out, all mechanisms are reset, and the next cycle begins.

[0053] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
