Description

Technical Field

[0001] This invention belongs to the field of wire stranding technology, and particularly relates to a wire stranding device for wire harness assembly processing. Background Technology

[0002] In the industrial production of wire harnesses, multiple wires need to be continuously transported and synchronously twisted before being transported to the subsequent sleeve processing station.

[0003] Currently available conventional wire stranding and conveying devices only have simple guiding and stranding structures. Under the condition of dynamic wire conveying and synchronous rotary stranding, the wires are prone to radial deviation and swaying, and the conveying trajectory is difficult to maintain. At the same time, most existing equipment is not equipped with integrated tension detection and automatic adjustment mechanisms, so it is impossible to monitor the tension changes of the wires in real time during the conveying process. The wires are easily damaged due to excessive tension, or the stranding is loose and the forming quality is poor due to insufficient tension. In addition, the coordination of the various conveying and stranding mechanisms in traditional equipment is weak, and the stranded wires are difficult to smoothly connect to the next process. The conveying connection between processes is not smooth, and the overall automation and continuous operation capabilities are insufficient, making it difficult to adapt to the efficient and stable processing requirements of modern wire harness production lines.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This equipment employs a multi-stage, coaxially rotating structure to complete the wire feeding and stranding operations. The well-organized layout of each functional component and the coordinated movement trajectories provide guidance and limit the wire throughout the entire process, effectively preventing deviation, swaying, and twisting during feeding and stranding. Simultaneously, a clamping structure reliably secures the wire coil and its ends, preventing material loosening or displacement during operation. Combined with the continuous correction of the wire's posture by the guiding components, the entire wire feeding and stranding process operates more smoothly, significantly reducing the probability of operational failures and ensuring the reliability of long-term continuous operation.

[0018] Compared to traditional equipment's inability to control conductor tension in real time, this invention integrates a tension detection component and a tension adjustment component to form a closed-loop control system. It can sense changes in conductor tension in real time throughout the entire process of wire feeding and stranding, accurately determine whether the tension is standard, too high, or too low, and automatically adjust the conductor's support position based on the detection results, dynamically correcting the wire tension. The entire control process is synchronized with the stranding and feeding actions, ensuring that the conductor tension is always maintained within a reasonable range, preventing problems such as wire breakage, loosening, and loose stranding due to abnormal tension, and adapting to the wire processing needs under different working conditions.

[0019] This equipment can directly connect to the rear-end insulating tube device. After the conductors are stranded, they can be seamlessly transferred using the traction structure, allowing the stranding process to be connected with subsequent processing steps, forming an integrated wire conveying and processing flow. This simplifies transfer operations and improves overall processing efficiency. The equipment has a high degree of integration, integrating multiple functions such as wire feeding, stranding, guiding, detection, and adjustment. It does not require many auxiliary devices, and the various actuators work in a highly coordinated manner. It can be matched with batch processing scenarios for wire harnesses and conductors, making it more widely applicable and significantly improving the convenience of actual use.

[0044] The operating principle of the present invention is described as follows:

[0045] In this invention, before the equipment is put into operation, the installation height of the support plate 3 is raised or lowered as a whole by relying on the extension and retraction drive of the first electric telescopic rod 2 fixed at the top of the multiple sets of base plates 1, so that the central axis of all processing components at the top of the support plate 3 is precisely aligned with the feeding and conveying station of the rear insulating tube device, ensuring the continuity and coaxiality of wire conveying, stranding and discharge, and laying the station foundation for subsequent wire conveying and processing.

[0046] After the workstation calibration is completed, the take-up drums carrying the wires to be processed are placed one by one inside the fixing blocks 46 on the side wall of the first fixing plate 45, so that the openings at both ends of the take-up drum are aligned with the positions of the second electric telescopic rods 48 inside the fixing blocks 46. Then, the first motor 49 on the side wall of the fixing block 46 is started. The output end of the first motor 49 drives the corresponding second electric telescopic rod 48 to complete the angle alignment adjustment, and then controls the second electric telescopic rod 48 to extend and retract outward, so that the support rod 410 connected to the telescopic end is fully inserted into the take-up drum. Further, multiple sets of third electric telescopic rods 411 on the rod wall of the support rod 410 are started. The telescopic ends of the third electric telescopic rods 411 drive the first clamping plate 412 to move synchronously. The first clamping plate 412 clamps and fixes the inside of the take-up drum, completing the limiting clamping of the wire roll to be processed, and preventing the problem of material roll deviation and shaking during wire conveying.

[0047] After the material roll is clamped, the wire ends on the outside of each winding drum are manually pulled and passed through the outside of the adjusting rod 55 of the tension adjusting component 6, the twisting hole 418 corresponding to the side wall of the second fixing plate 417, and the auxiliary hole 424 on the side wall of the connecting plate 423 in sequence, and finally extended to the inside of the fixing ring 429 on the side of the support plate 3. This completes the through-type guiding layout of multiple wires, so that all wires to be twisted are arranged along a unified conveying path. After the layout is completed, the fourth electric slide rail 426 inside the second groove 425 is activated, driving the fourth slide plate 427 to move horizontally, causing the side rod 428 and the top fixing ring 429 to adapt to the wire conveying position. Then, the fourth electric telescopic rod 430 inside the fixing ring 429 is activated, and the ends of multiple wires are clamped and fixed as a whole through the second clamping plate 431 connected to its telescopic end, locking the starting position of wire conveying and ensuring that the wire tension is uniform in the early stage of the twisting operation.

[0048] After wire clamping and end positioning are completed, the equipment enters the synchronous conveying and stranding mode. The first electric slide rail 43 inside the first mounting ring 42, the second electric slide rail 415 inside the second mounting ring 414, and the third electric slide rail 421 inside the third mounting ring 420 are started synchronously. These three sets of annular electric slide rails drive the corresponding first slide plate 44, second slide plate 416, and third slide plate 422 to rotate synchronously and in the same direction, thereby causing the first fixing plate 45, second fixing plate 417, and connecting plate 423 to rotate coaxially. The device rotates in a step-by-step manner. The first fixed plate 45 drives the fixed wire roll to revolve synchronously, and the first motor 49 continuously drives the second electric telescopic rod 48 and the roll to rotate, so as to achieve uniform and continuous unwinding and feeding of the wire. The twisting hole 418 of the second fixed plate 417 gathers and limits multiple wires, and completes the cross-twisting of the wires with the rotation. The auxiliary hole 424 of the connecting plate 423 guides and corrects the wires at the rear end during the twisting process, limits the radial displacement of the wires, and ensures that the twisting spacing of multiple wires is uniform and the forming is regular.

[0049] While the stranding operation is underway, the fourth electric slide rail 426 continuously drives the fourth slide plate 427 to slide at a constant speed toward the insulating tube device. The second clamping plate 431 clamps the end of the conductor and continuously pulls and feeds the conductor, so that the conductor can be continuously stranded during dynamic conveying. The linear traction conveying speed and the rotary stranding speed are precisely matched to avoid problems such as wire accumulation, pulling, and twisting. When the fourth slide plate 427 slides to the end of its stroke, the feeding mechanism of the rear insulating tube device connects and clamps the stranded end of the conductor. Then, the fourth electric telescopic rod 430 is controlled to reset, releasing the clamping limit of the second clamping plate 431 on the conductor. The insulating tube device continues to pull and convey the wire, realizing a seamless connection between the stranding process and the insulating tube processing process, and achieving continuous wire conveying and processing.

[0050] To ensure the stability of the entire wire conveying and stranding process, after the wire is in place and the end is fixed, the fifth electric telescopic rod 53 on the outside of the adjusting plate 52 is activated. The U-plate 54 at its telescopic end supports the displacement of the adjusting rod 55, so that the adjusting rod 55 fits against the outer wall of the wire, providing radial support and limiting for the conveying wire, and presets the standard conveying tension state of the wire.

[0051] During tension testing, the sixth electric telescopic rod 63 on the outer side of the testing disc 62 is activated, which drives the clamping block 64 and the overall testing structure to move towards the conductor. At the same time, the second motor 66 on the side wall of the clamping block 64 is activated. The second motor 66 drives the round rod 65 and the testing cylinder 67 to rotate as a whole, and finely adjusts the tilt angle of the limiting plate 616. The connecting spring 619 and the pressure sensor 620 in the mounting groove 618 at the bottom of the limiting plate 616 are in real time contact with the outer wall of the test conductor. Only when the two sets of pressure sensors 620 detect a uniform pressure signal at the same time is it determined that the tilt angle of the limiting plate 616 is completely matched with the tilt angle of the conductor conveying, ensuring that the tension testing benchmark is accurate.

[0052] After the baseline alignment is completed, the sixth electric telescopic rod 63 continues to advance, causing the limiting plate 616 and the inner guide rod 617 to fit against the outer wall of the wire. During the wire conveying process, the limiting plate 616 generates reverse resistance, squeezing the detection spring 68 inside the detection cylinder 67 to undergo elastic deformation, pushing the detection rod 69 to stably retract under the limiting guidance of the slide groove 610 and the slider 611. When the first conductive plate 612 on the rod wall of the detection rod 69 contacts the third conductive plate 614 inside the detection cylinder 67, the stroke of the sixth electric telescopic rod 63 is locked, and this position is used as the baseline detection position for the standard wire conveying tension.

[0053] During the continuous feeding and stranding process of the wire, the tension is dynamically adjusted in real time through the contact signal feedback of the conductive plate: If the wire is slack and the tension is too low during the feeding process, the first conductive plate 612 rebounds and moves upward with the detection rod 69 and contacts the second conductive plate 613. The equipment immediately triggers tension compensation, controls the fifth electric telescopic rod 53 to extend outward, drives the adjusting rod 55 to radially push the wire, increases the wire feeding tension, until the first conductive plate 612 resets and contacts the third conductive plate 614, and stops adjusting after maintaining the standard tension; If the wire is taut and the tension is too high, the first conductive plate 612 moves downward with the detection rod 69 and contacts the fourth conductive plate 615. The equipment triggers tension relief adjustment, controls the fifth electric telescopic rod 53 to retract inward, drives the adjusting rod 55 to relax the wire, reduces the wire feeding tension, until the first conductive plate 612 returns to the reference position;

[0054] After a single tension adjustment is completed, the equipment recalibrates the detection benchmark by finely adjusting the tilt angle of the limit plate 616 via the second motor 66 and the pressure sensor 620, ensuring that the guide rod 617 always fits the wire conveying trajectory after tension adjustment. It continuously monitors the tension status of the wire conveying. The entire process achieves synchronous coordination of wire conveying, rotational stranding, real-time tension detection, and dynamic closed-loop adjustment, ensuring constant tension, smooth conveying, and no deviation or pulling of multiple wires during continuous conveying and stranding, effectively improving the stranding quality of the wire harness and the efficiency of continuous processing.
