Abstract
Description
Technical Field
[0001] This invention belongs to the field of slip ring alignment technology, and more specifically, relates to a fully mechanical slip ring up-and-down alignment device and its usage method. Background Technology
[0002] In energy and signal transmission between rotating and fixed mechanisms, slip rings are key components for achieving 360-degree continuous rotation. With the development of industrial technology, traditional mechanical contact slip rings are no longer sufficient to meet the demands of high-volume, high-reliability transmission. Non-contact fiber optic slip rings or wireless optical transmission solutions based on spatial optical communication principles are gradually becoming mainstream. In this non-contact transmission, the vertical alignment of the slip ring is crucial: only when the optical signal transmitting and receiving units at both ends maintain precise coupling and alignment on the spatial axis can the signal transmission gain be maximized, the bit error rate reduced, and communication interruptions caused by rotation prevented.
[0003] In existing technologies, achieving vertical alignment of a slip ring typically relies on a complex electromechanical control system. Specifically, high-precision photoelectric encoders or angle sensors are placed at both ends of the slip ring to monitor their relative rotational positions in real time. Simultaneously, the system integrates a high-performance servo motor and an electronically controlled drive module. By collecting position feedback data from the sensors and using control algorithms such as PID controllers to drive the motor for fine-tuning, the system corrects the pointing of the optical elements in real time during dynamic rotation, striving to keep the emitted beam locked within the effective photosensitive area of the receiver.
[0004] However, the alignment methods in the aforementioned prior art have significant drawbacks. First, the system structure is overly complex. The introduction of motors, encoders, and multiple electronic control units significantly increases the size, weight, and hardware cost of the slip ring, making it difficult to meet the needs of miniaturized equipment. Second, the alignment process places extremely high demands on the accuracy and response speed of the sensors. Under conditions of ultra-high-speed rotation or severe vibration, the delay of the closed-loop control system often leads to dynamic alignment failure, resulting in a significant decrease in communication quality. Finally, the excessive number of electronic components reduces the system's mean time between failures (MTBF), resulting in high maintenance costs and difficulty in long-term stable operation in harsh environments. Summary of the Invention
[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a fully mechanical slip ring alignment device and its usage method. When the upper gear of the slip ring rotates, it drives the upper open gear to rotate synchronously via an upper transmission component, thereby causing the upper pointing component to rotate around the end connected to the outer cylinder of the slip ring. When the lower gear of the slip ring rotates, it drives the lower open gear to rotate synchronously via a lower transmission component, thereby causing the lower pointing component to rotate around the end connected to the inner cylinder of the slip ring. The rotation of the upper and lower gears of the slip ring is transmitted to the upper and lower pointing components. By monitoring the axial position of the upper and lower pointing components, it is determined whether the upper and lower gears of the slip ring are aligned, thus enabling targeted control of the alignment of the upper and lower ends of the slip ring. By using two transmission components to transmit the relative rotational motion of the slip ring into the rotational motion of one end of the two pointing components at the same angular velocity as the slip ring, the upper and lower pointing components of the slip ring are automatically aligned as the slip ring rotates, allowing for purely mechanical alignment of the slip ring with fewer components.

The first dual-axis rotating disk is sleeved on the upper shaft and slides along its axial direction. The first dual-axis rotating disk also has two degrees of freedom of rotation in two directions. The second dual-axis rotating disk is fixed on the upper shaft and also has two degrees of freedom of rotation in two directions, so that the upper shaft can rotate freely around the second dual-axis rotating disk.
[0009] Furthermore, the lower transmission component includes a third coaxial gear and a fourth coaxial gear, which are coaxially arranged and connected by a lower transmission shaft; The third coaxial gear meshes with the lower gear of the slip ring, and the fourth coaxial gear meshes with the lower open gear.
[0010] Furthermore, the lower pointing member includes a lower shaft, one end of which is provided with a third dual-axis rotating disk and the other end is provided with a fourth dual-axis rotating disk. The third dual-axis rotating disk is located inside the circular opening of the lower open gear, and the fourth dual-axis rotating disk is connected to the inner cylinder of the slip ring.

The fourth dual-axis rotating disk is fixed on the lower shaft and also has two degrees of freedom for rotation in two directions, so that the lower shaft can rotate freely around the fourth dual-axis rotating disk.
[0011] Furthermore, the first dual-axis rotating disk, the second dual-axis rotating disk, the third dual-axis rotating disk, and the fourth dual-axis rotating disk are dual-axis rotating structures or central sphere structures.
[0012] Furthermore, the upper and lower shafts need to rotate at the same angular velocity as the upper and lower ends of the slip ring.

Let be the pitch circle diameter of the first and third coaxial gears. The pitch circle diameters of the second and fourth coaxial gears are given. Let be the pitch circle diameter of the upper and lower open gears. The angular velocity of the upper or lower gear of the slip ring. From this, the relationship between the pitch circle diameters of each gear can be obtained: .
[0013] Furthermore, to achieve pointing alignment, the centers of the four dual-axis rotating disks must be aligned on a straight line when the slip ring rotates to any angle. Let the slip ring rotation angle be... When the four dual-axis rotating disks are located, their centers are in the following order: H, J, K, I. A spatial rectangular coordinate system is established with the center point of the lower gear of the slip ring as the origin. In the plane where the lower gear of the slip ring is located, the direction pointing downwards is the x-axis direction, and the direction pointing upwards is the z-axis direction. when At that time, the center coordinates of the four dual-axis rotary disks are ensured through assembly as follows: , when At that time, the center coordinates of the four dual-axis rotary disks are: , in, The distance between the central axis of the upper open gear and the lower open gear and the central axis of the slip ring. The distance from the central axis of the upper and lower open gears to the center of their circular openings. This is the distance between the centers of the upper and lower gears of the slip ring. This refers to the distance between the centers of the first and second coaxial gears, and the distance between the centers of the third and fourth coaxial gears. The distance between the centers of the first and second dual-axis rotary disks along the z-axis, and the distance between the centers of the third and fourth dual-axis rotary disks along the z-axis.
[0014] Furthermore, the following vector is obtained between the center coordinates of the four dual-axis rotating disks: , , , At this point, the four points being collinear is equivalent to... Proportional, therefore we obtain the following collinear proportion: , Since the slip ring design is determined, the corresponding and It has already been determined that, at this point, the design will be based on the specific spatial conditions. , or A parameter value is preset, and then the remaining two parameter values are determined using the above proportion. This ensures that the centers of the four dual-axis rotary disks are always on a straight line, thus achieving the desired rotation angle of the slip ring. Any pointer pointing down.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.
[0021] Example 1 like Figure 1-4As shown, this embodiment of the invention provides a fully mechanically aligned slip ring, including an upper slip ring gear 1 and a lower slip ring gear 2, an upper alignment component 3 that moves with the upper slip ring gear 1, and a lower alignment component 4 that moves with the lower slip ring gear 2. The upper slip ring gear 1 is located at the top of the inner cylinder of the slip ring, and the lower slip ring gear 2 is located at the bottom of the outer cylinder of the slip ring. The upper alignment component 3 includes an upper transmission member 31 and an upper open gear 32. The upper transmission member 31 is connected to the upper slip ring gear 1 and the upper open gear 32 respectively, transmitting the movement of the upper slip ring gear 1 to the upper open gear 32. The upper open gear 32 has a circular opening near its edge, and an upper pointing member 33 is provided inside the circular opening. One end of the upper pointing member 33 is rotatably connected to the outer cylinder of the slip ring, and the other end is rotatably connected to the circular opening of the upper open gear 32. The lower alignment assembly 4 includes a lower transmission member 41 and a lower open gear 42. The lower transmission member 41 is connected to the lower slip ring gear 2 and the lower open gear 42 respectively, transmitting the movement of the lower slip ring gear 2 to the lower open gear 42. The lower open gear 42 has a circular opening near its edge, and a lower pointing member 43 is provided inside the circular opening. One end of the lower pointing member 43 is rotatably connected to the inner cylinder of the slip ring, and the other end is rotatably connected to the circular opening of the lower open gear 42. When the upper slip ring gear 1 rotates, it drives the upper open gear 32 to rotate synchronously through the upper transmission member 31, thereby driving the upper pointing member 33 to rotate around the end connected to the outer cylinder of the slip ring. When the lower slip ring gear 2 rotates, it drives the lower open gear 42 to rotate synchronously through the lower transmission member 41, thereby driving the lower pointing member 43 to rotate around the end connected to the inner cylinder of the slip ring. The rotation of the upper gear 1 and lower gear 2 of the slip ring is transmitted to the upper pointing member 33 and lower pointing member 43. By monitoring the axial position of the upper pointing member 33 and lower pointing member 43, it is determined whether the upper gear 1 and lower gear 2 of the slip ring are aligned, thereby enabling targeted control of the alignment of the upper and lower ends of the slip ring. Two transmission components are used to transmit the relative rotational motion of the slip ring into the rotational motion of one end of each of the two pointing members at the same angular velocity as the slip ring. This achieves automatic alignment of the upper and lower pointing members as the slip ring rotates, allowing for purely mechanical alignment of the slip ring with fewer components.
[0022] The upper gear 1 and the lower gear 2 of the slip ring have circular holes with the same diameter as the slip ring at their centers, and a ring of external teeth is provided along their circumference.
[0023] like Figure 2As shown, the upper transmission component 31 includes a first coaxial gear 311 and a second coaxial gear 312, which are coaxially arranged and connected by an upper transmission shaft 313. The first coaxial gear 311 meshes with the upper gear 1 of the slip ring, and the second coaxial gear 312 meshes with the upper open gear 32. When the inner cylinder of the slip ring rotates, the upper gear 1 of the slip ring drives the first coaxial gear 311 to rotate, causing the second coaxial gear 312 to rotate coaxially with it, and then driving the upper open gear 32 to rotate around its central axis.
[0024] like Figure 4 As shown, the upward pointing member 33 includes an upper shaft 333. One end of the upper shaft 333 is provided with a first dual-axis rotating disk 331, and the other end is provided with a second dual-axis rotating disk 332. The first dual-axis rotating disk 331 is disposed in the circular opening of the upper open gear 32, and the second dual-axis rotating disk 332 is connected to the outer cylinder of the slip ring. The first dual-axis rotating disk 331 is sleeved on the upper shaft 333 and slides along its axial direction. The first dual-axis rotating disk 331 also has two degrees of freedom of rotation in two directions. The second dual-axis rotating disk 332 is fixed on the upper shaft 333 and also has two degrees of freedom of rotation in two directions, so that the upper shaft 333 can rotate freely around the second dual-axis rotating disk 332.
[0025] The lower transmission component 41 includes a third coaxial gear 411 and a fourth coaxial gear 412, which are coaxially arranged and connected by a lower transmission shaft 413. The third coaxial gear 411 meshes with the lower slip ring gear 2, and the fourth coaxial gear 412 meshes with the lower open gear 42. When the outer cylinder of the slip ring rotates, the lower slip ring gear 2 drives the third coaxial gear 411 to rotate, causing the fourth coaxial gear 412 to rotate coaxially with it, and then driving the lower open gear 42 to rotate around its central axis.
[0026] The lower pointing member 43 includes a lower shaft 433. One end of the lower shaft 433 is provided with a third dual-axis rotating disk 431, and the other end is provided with a fourth dual-axis rotating disk 432. The third dual-axis rotating disk 431 is disposed in the circular opening of the lower open gear 42, and the fourth dual-axis rotating disk 432 is connected to the inner cylinder of the slip ring. The third dual-axis rotating disk 431 is sleeved on the lower shaft 433 and slides along its axial direction. The third dual-axis rotating disk 431 also has two degrees of freedom of rotation in two directions. The fourth dual-axis rotating disk 432 is fixed on the lower shaft 433 and also has two degrees of freedom of rotation in two directions, so that the lower shaft 433 can rotate freely around the fourth dual-axis rotating disk 432.
[0027] Understandably, when the inner cylinder of the slip ring rotates, the upper slip ring gear 1 drives the upper open gear 32 to rotate, causing the circular opening of the upper open gear 32 to rotate around its central axis. At this time, the outer cylinder of the slip ring remains stationary, the position of the second double-axis rotating disk 332 is fixed, and the upper shaft 333 rotates around the second double-axis rotating disk 332 under the push of the upper open gear 32; similarly, the lower shaft 433 rotates around the fourth double-axis rotating disk 432 under the push of the lower open gear 42. When the axes of the upper shaft 333 and the lower shaft 433 are on the same straight line, it indicates that the upper and lower ends of the slip ring are aligned.
[0028] As a further preferred embodiment, the first dual-axis rotating disk 331, the second dual-axis rotating disk 332, the third dual-axis rotating disk 431, and the fourth dual-axis rotating disk 432 are dual-axis rotating structures or central spherical structures. The dual-axis rotating structure includes inner and outer sleeves, with the inner sleeve rotating coaxially with the outer sleeve. A rotating shaft is provided on the outer sleeve and is mounted on a mounting base, rotating around the mounting base. The mounting base is located within the circular openings of the upper open gear 32 and the lower open gear 42, as well as on the inner and outer cylinders of the slip ring. The rotating shaft is perpendicular to the upper shaft 333 or the lower shaft 433.
[0029] The upper shaft 333 and lower shaft 433 need to rotate at the same angular velocity as the upper and lower ends of the slip ring. First, it is necessary to ensure that the two side-opening gears rotate at the same angle as the slip ring, which requires satisfying the following formula: , in, Let be the pitch circle diameter of the upper slip ring gear 1 and the lower slip ring gear 2. The pitch circle diameters of the first coaxial gear 311 and the third coaxial gear 411 are... The pitch circle diameters of the second coaxial gear 312 and the fourth coaxial gear 412 are... The pitch circle diameters of the upper open gear 32 and the lower open gear 42 are... The angular velocity of the upper gear 1 or the lower gear 2 of the slip ring; From this, the relationship between the pitch circle diameters of each gear can be obtained: , To achieve directional alignment, the centers of the four dual-axis rotary disks must be aligned in a straight line when the slip ring rotates to any angle. Let the slip ring rotation angle be... When the four dual-axis rotating disks are positioned, their centers are located in the following order: H, J, K, I. A spatial rectangular coordinate system is established with the center point of the lower slip ring gear 2 as the origin. In the plane containing the lower slip ring gear 2, the direction pointing downwards towards the pointing component 43 is the x-axis, and the direction pointing towards the upper slip ring gear 1 is the z-axis. When... At that time, the center coordinates of the four dual-axis rotary disks are ensured through assembly as follows: , when At that time, the center coordinates of the four dual-axis rotary disks are: , in, The distance between the central axis of the upper open gear 32 and the lower open gear 42 and the central axis of the slip ring. The distance from the central axis of the upper open gear 32 and the lower open gear 42 to the center of their circular openings. The distance between the centers of the upper slip ring gear 1 and the lower slip ring gear 2. The distances between the centers of the first coaxial gear 311 and the second coaxial gear 312, and the distances between the centers of the third coaxial gear 411 and the fourth coaxial gear 412 are respectively. The distance between the centers of the first dual-axis rotary disk 331 and the second dual-axis rotary disk 332 in the z-axis direction, and the distance between the centers of the third dual-axis rotary disk 431 and the fourth dual-axis rotary disk 432 in the z-axis direction.
[0030] Then we can obtain the following vector formed by the center coordinates of the four dual-axis rotary disks: , , , At this point, the four points being collinear is equivalent to... Proportional, therefore we obtain the following collinear proportion: , Since the slip ring design is determined, the corresponding and It has already been determined that, at this point, the design will be based on the specific spatial conditions. , or A parameter value is preset, and then the remaining two parameter values are determined using the above proportion. This ensures that the centers of the four dual-axis rotary disks are always on a straight line, thus achieving the desired rotation angle of the slip ring. Any pointer pointing down.
[0031] As a further preferred embodiment, the upper transmission member 31, the upper open gear 32, the lower transmission member 41, and the lower open gear 42 are all connected to the support structure via rotating shafts to limit their movement, so that they can only rotate around their own central axis and cannot produce any movement other than rotation.
[0032] Example 2 like Figure 5 As shown, this embodiment of the invention provides a method for using a fully mechanically aligned slip ring, specifically including the following steps: S100. Based on the specific dimensions of the slip ring, determine the specific dimensions and spatial position to obtain... and Parameter values; S200, to , or One of the parameters is preset to a value, which is determined using the collinearity ratio formula. , or The values of the other two parameters; S300.

Design the dimensions of the upper alignment component 3 and the lower alignment component 4 according to the determined parameters, and achieve pointing alignment at any angle of slip ring rotation after assembly.
