Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and more specifically to a tension-adjustable wire harness tape winding device. Background Technology

[0002] In wire harness processing, tape is typically wrapped around the wire harness to provide insulation, wear resistance, noise reduction, and wire harness tidying. Existing wire harness winding equipment often uses a method where the tape roller revolves with a rotating mechanism, and the wire harness is fed axially to achieve automatic winding. However, in practical applications, traditional equipment generally suffers from the following problems: First, the tape tension is difficult to control precisely, relying on operator experience, leading to inconsistent winding tightness, affecting insulation performance and appearance quality; second, it has poor adaptability to different tape materials and wire harnesses of different diameters, lacking dynamic adjustment capabilities; third, at the winding end, because the wire harness end position is fixed, the relative position between the tape roller's center of rotation and the wire harness end changes, easily resulting in incomplete winding, tape accumulation, or missed winding, affecting finished product yield; fourth, the coordination between various mechanisms is insufficient, making it difficult to achieve closed-loop control of the entire process of winding pitch, tension, and end treatment.

[0018] When using this invention, the coordinated operation of the rotating mechanism 3, the feeding mechanism 4, the tensioning mechanism 5, the fixing mechanism 6, and the adjusting mechanism 7 enables automated tape winding onto the surface of the wire harness, and the tape tension is monitored and dynamically adjusted in real time during the winding process; the specific working process is as follows: 1. Material loading and initial positioning The operator first unscrews the fixing bolt 4-8 and removes the moving rod 4-6 from the first mounting bracket 4-4; then inserts the front and rear ends of the wire harness tape roller 4-9 into the first through hole 4-51 at the inner end of the fixing rod 4-5 and the second through hole 4-61 at the inner end of the moving rod 4-6, respectively. Then, the moving rod 4-6 is reset so that the fixing bolt 4-8 passes through the moving rod 4-6 and is screwed and locked to the mounting block 4-7, thus completing the installation of the wire harness tape roller 4-9. Activate lifting cylinder 6-5. The movable end of lifting cylinder 6-5 extends, pushing mounting plate 6-4 and moving arc rod 6-3 upward, causing moving arc rod 6-3 to separate from fixed arc rod 6-2. The operator places the wire harness to be wound horizontally on the arc-shaped support surface of fixed arc rod 6-2. Then, lifting cylinder 6-5 resets, the movable end retracts, and moving arc rod 6-3 presses down on the wire harness, forming a stable clamping of the wire harness together with fixed arc rod 6-2. The operator manually pulls out the starting section of the wire harness tape and pre-wraps it around the surface of the wire harness 1 to 2 times to form the starting point of the wrapping, ensuring that the tape is not easy to come loose during the subsequent automatic wrapping process; 2. Tension preset and dynamic adjustment Activate tension cylinder 5-4, extending its movable end to push mounting bracket 5-5 and tension roller 5-6 towards the wire harness tape until tension roller 5-6 presses against the tape surface. Tension cylinder 5-4 has a built-in pressure sensor that monitors the cylinder's output pressure in real time and converts the pressure signal into a tension force value. The operator sets the target tension force range based on the tape material and winding process requirements. During subsequent winding, the pressure sensor provides continuous feedback, and the control system adjusts the air pressure output of tension cylinder 5-4 to maintain the pressure of tension roller 5-6 on the tape within the set range, achieving closed-loop control of the tape tension force. 3. Winding Main Motion: Coordination of Revolution and Axial Feed Start the drive motor 3-5. The output shaft of the drive motor 3-5 drives the drive gear 3-4 to rotate through the coupling. The drive gear 3-4 meshes with the bottom external teeth of the gear ring 3-1, driving the gear ring 3-1 to rotate around its central axis. The gear ring 3-1 achieves radial limiting and stable support through the first limit slide rail 3-2 and the first limit slider 3-3 on the left and right sides, ensuring that the gear ring 3-1 does not eccentrically swing during rotation. The gear ring 3-1 has an inner and outer gear ring structure, and its inner side meshes with the first gear 4-1 and the second gear 5-1 respectively. When the gear ring 3-1 rotates, the first gear 4-1 and the second gear 5-1 roll along the inner side of the gear ring 3-1 under the drive of the gear ring 3-1. The first gear 4-1 is screwed to the second limiting slider 4-3 through a shaft and bearing. The second limiting slider 4-3 is slidably set on the second limiting slide rail 4-2. Therefore, while the first gear 4-1 revolves with the gear ring 3-1, it drives the first mounting bracket 4-4 and the wire harness tape roller 4-9 to move horizontally along the second limiting slide rail 4-2. Similarly, gear 5-1 drives mounting bracket 5-3 and tensioning mechanism 5 to move synchronously, ensuring that tensioning roller 5-6 always follows the winding point and maintains continuous tension on the tape. At this time, the wire harness tape roller 4-9 revolves around the wire harness, and the tape is continuously pulled out and wound on the surface of the wire harness during the revolution. At the same time, the moving motor 6-7 is started, and the output shaft of the moving motor 6-7 drives roller 6-6 to rotate. Roller 6-6 is movably inserted into the fixed arc rod 6-2 and contacts the surface of the wire harness. Through friction, it drives the wire harness to move slowly along its axis. The axial movement of the wire harness and the revolution of the tape roller combine to form a spiral winding trajectory, so that the tape is evenly covered on the surface of the wire harness. 4. Final winding and position compensation When the winding process approaches the end of the wire harness, the relative position between the revolution center of the wire harness tape rollers 4-9 and the end of the wire harness changes because the end of the wire harness is fixed. This may result in incomplete winding at the end or tape accumulation. To solve this problem, the equipment is equipped with an adjustment mechanism 7. Start the adjusting motor 7-3, and the output shaft of the adjusting motor 7-3 drives the screw 7-5 to rotate; the screw 7-5 is screwed to the connecting plate 7-4 through the thread, and the connecting plate 7-4 is fixed between the two guide blocks 7-1 on the right side; the guide blocks 7-1 are slidably mounted on the guide rail 7-2 and are fixedly connected to the fourth mounting bracket 6-1; when the screw 7-5 rotates, the connecting plate 7-4 moves along the axial direction of the screw 7-5, driving the fourth mounting bracket 6-1 and the fixing mechanism 6 as a whole to move to the right along the guide rail 7-2; The overall displacement of the fixing mechanism 6 compensates for the position of the end of the wire harness relative to the center of rotation of the tape roller, ensuring that the tape can still complete the full number of turns at the end of the wire harness, and avoiding the occurrence of unwound sections or loose winding. 5. Full-process collaborative control Throughout the winding process, the drive motor 3-5, the moving motor 6-7, the adjusting motor 7-3, the tensioning cylinder 5-4, and the lifting cylinder 6-5 are all controlled in a unified and coordinated manner by the control system. The control system adjusts the speed, position, and output force of each actuator in real time according to the set parameters and sensor feedback signals to ensure uniform winding pitch, stable tension, and complete end processing. After winding is completed, each mechanism resets in sequence: tension cylinder 5-4 retracts, tension roller 5-6 disengages from the tape; drive motor 3-5 stops; moving motor 6-7 stops; lifting cylinder 6-5 raises moving arc rod 6-3 again, and the operator takes out the wound wire harness, and the next cycle can be started.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the coordinated operation of the rotating mechanism 3, the feeding mechanism 4, the tensioning mechanism 5, the fixing mechanism 6 and the adjusting mechanism 7, the fully automated operation of wrapping tape on the surface of the wire harness is realized, which significantly improves production efficiency and wrapping consistency. 2. The tensioning mechanism 5 has a built-in pressure sensing device that forms a closed-loop control with the control system. It can adjust the output pressure of the tensioning cylinder 5-4 in real time according to the material of the tape and the process requirements, so that the pressure of the tensioning roller 5-6 on the tape is always maintained within the set range, effectively avoiding the problem of winding too loosely or too tightly. 3. The meshing structure of the gear ring 3-1 with the first gear 4-1 and the second gear 5-1, combined with the second limiting slide rail 4-2, enables the wire harness tape roller 4-9 and the tensioning mechanism 5 to move horizontally synchronously during the revolution, ensuring that the tensioning roller 5-6 always follows the movement of the winding point, thus achieving the continuity and uniformity of the tensioning effect. 4. By adjusting the screw 7-5 driven by the motor 7-3 to drive the overall displacement of the fixing mechanism 6, the position of the end of the wire harness relative to the center of the belt roller is dynamically compensated to ensure that the end is completely and tightly wound, thus avoiding winding defects caused by position changes.
