[0017] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0018] Reference Figures 1 to 3 The application provides a servo rotating device for collecting 12mm wide flat cable in a performance place, comprising a bottom plate 1, two vertical plates 2 symmetrically arranged on the upper surface of the bottom plate 1, a winding drum assembly rotatably connected between the two vertical plates 2, the winding drum assembly comprising a winding drum shaft 3 and a winding drum body fixedly sleeved on the winding drum shaft 3, the width of the winding drum body being matched with the 12mm wide flat cable, a driving mechanism for driving the winding drum shaft 3 to rotate, the driving mechanism comprising a servo motor 4 and a speed reducer 5 connected with the output end of the servo motor 4, the output end of the speed reducer 5 being connected with one end of the winding drum shaft 3, a through-hole type conductive slip ring 6 arranged on the vertical plate 2, the through-hole type conductive slip ring 6 being sleeved on the winding drum shaft 3, and a plurality of support rib plates 7 arranged at the connection between the vertical plate 2 and the bottom plate 1. By integrating servo driving, a through-hole conductive slip ring and a reinforced support structure, a winding and unwinding system special for 12mm wide flat cable is constructed. The core beneficial effect is to realize high-precision speed synchronization, stable uninterrupted power supply / signal transmission and excellent structural rigidity, and fundamentally solve the three core problems of neatness, matching degree and stability in the winding and unwinding of mobile equipment cable in a performance place.

[0019] In some embodiments, the winding drum body comprises a drum body 8 and baffles 9 arranged on both sides of the drum body 8, the diameter of the baffles 9 is 1260mm, and the width of the drum body 8 is 168mm. In this embodiment, the diameter of the baffles 9 is set to 1260mm, which provides sufficient winding space for the cable and prevents interlayer extrusion; the width of the drum body 8 is accurately designed to be 168mm, which forms an optimal matching ratio with the width of the 12mm cable, effectively limits the axial movement range of the cable during winding from the physical space, and lays a structural foundation for the neat and compact arrangement of the cable.

[0020] In some embodiments, the winding drum shaft 3 is installed on the vertical plate 2 through a bearing seat 10, and a sleeve and a round nut for axial positioning are further sleeved on the winding drum shaft 3. In this embodiment, the winding drum shaft 3 is supported by the bearing seat 10, ensuring the rotation flexibility and coaxiality; the sleeve and the round nut are used for axial positioning and locking, effectively preventing the axial movement of the winding drum body under the high-speed start-stop or forward-reverse rotation working condition, improving the rigidity and running stability of the entire transmission system, and prolonging the service life of the bearing.

[0021] In some embodiments, the speed reducer 5 is a worm reducer. There are two major advantages of using a worm reducer: one is that it can achieve a large transmission ratio and self-locking function, effectively preventing the drum from rotating in the reverse direction due to the weight of the cable in the power-off state, thereby improving the safety of the equipment; the second is that the structure is compact, which is conducive to arranging a large reduction ratio transmission in a limited installation space.

[0022] In some embodiments, the through-hole conductive slip ring 6 is fixed to the vertical plate 2 by a conductive slip ring support. In this embodiment, the through-hole conductive slip ring 6 is stably installed on the vertical plate 2 by a separate conductive slip ring support, achieving modular separation installation of power transmission and signal / power transmission. This design not only facilitates individual installation, debugging, and maintenance, but also avoids direct transmission of vibrations from rotating parts to the conductive slip ring, thereby improving its working stability and service life.

[0023] In some embodiments, the base plate 1 and the vertical plate 2 are made of Q235 steel plates, the thickness of the base plate 1 is 8 mm, and the thickness of the vertical plate 2 is 8 mm and the height is 860 mm. In this embodiment, the base plate 1 and the vertical plate 2 are specified to be made of Q235 steel plates with a thickness of 8 mm, and the vertical plate 2 has a height of 860 mm. This calculated rigid structure provides an extremely stable support foundation for the drum with a diameter of 1260 mm, effectively resisting the large overturning moment generated during cable winding and unwinding, and ensuring that the entire device does not deform or shake under long-term heavy load.

[0024] In some embodiments, the support rib plate 7 is a triangular steel plate made of Q235 steel with a thickness of 10 mm, which is welded to the connection between the vertical plate 2 and the base plate 1. In this embodiment, a Q235 triangular steel plate with a thickness of 10 mm is used and welded to the connection between the vertical plate 2 and the base plate 1. The triangular structure achieves optimal force flow transmission, efficiently dispersing and transmitting the complex loads (radial force, axial force) generated by the drum work to the base plate 1, greatly enhancing the bending and torsional strength of the connection part, which is a key design to ensure the stability of the overall structure.

[0025] In some embodiments, a pressure roller mechanism 11 is also included, which includes a rubber roller for elastically holding and guiding the flat cable on the drum body, the rubber roller being rotatably connected between the two vertical plates 2; the rubber roller is made of nitrile rubber. The added pressure roller mechanism 11 in this embodiment has a nitrile rubber roller that can apply flexible elastic pressure to the cable. This design combines the functions of guiding and flattening: it can guide the cable to enter the corresponding position of the drum accurately, preventing deviation, and it can also flatten any possible cable wrinkles or bulges, ensuring that each layer of cable is flat and tight, which is a direct component for achieving high uniformity of winding.

[0026] The specific workflow of the application: after power on, the servo drive system and the upper control unit establish communication and enter the standby state; when the stage equipment starts to move, the upper control unit sends speed and direction instructions to the servo motor 4 in real time, the servo motor 4 adjusts the output accurately according to the instructions and the encoder feedback, and then drives the drum shaft 3 and the drum body to rotate synchronously through the worm reducer to increase torque and reduce speed, so as to realize the winding or unwinding of the flat cable, and ensure that the cable winding speed always matches the equipment moving speed; in this process, the through-hole conductive slip ring 6 continuously maintains stable transmission of power and signals in the rotating state, and the compression roller mechanism 11 ensures that the cable is wound flat and neatly on the drum by elastically holding and guiding the cable through the nitrile rubber roller; during the whole operation, the rigid support formed by the bottom plate 1, the vertical plate 2 and the triangular support rib plate 7 always bears and disperses various loads to ensure the stability and reliability of the device; when the equipment stops moving, the servo motor 4 is immediately braked, and the system returns to the standby state, completing a working cycle.

[0027] The patent introduces the dynamic torque balance theory, that is, given a certain torque (which can be set), the torque overcomes the weight of the cable to give a certain tension (such as 10 kg), and the cable is wound and unwound with the lifting device while maintaining tension. The constant torque ring and speed ring of the servo motor 4 are nested and operated. At the same time, the upper automatic control system is introduced to realize accurate control of multiple machines, constant torque and dynamic speed.

[0028] The application can effectively hold and guide the cable through the drum body precisely matched with the 12mm wide flat cable and the compression roller mechanism 11 composed of the rubber roller, fundamentally solving the problems of uneven winding and easy cable wear; the driving mechanism composed of the servo motor 4 and the reducer 5 can realize precise and rapid synchronization of the winding and unwinding speed with the equipment moving speed, effectively avoiding cable loosening or excessive tension; the application of the through-hole conductive slip ring 6 provides a stable and reliable rotating connection interface, ensuring the continuity of power and signal transmission; the reinforced structure design of the bottom plate 1, the vertical plate 2 and the triangular support rib plate 7 significantly improves the overall rigidity and stability of the device, prolonging the service life; the utility model significantly improves the reliability and automation level of cable winding management in performance venues.

[0029] Finally, it should be noted that: the above description is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features.
