Description

Technical Field

[0001] This utility model belongs to the field of slip ring technology, and in particular to a wireless slip ring mandrel. Background Technology

[0002] Slip ring mandrels are widely used in slip ring products such as security PTZ camera slip rings, gimbal slip rings, and drone slip rings. Existing cap-type slip ring mandrels use a structure where a copper ring is welded to a wire and then injection molded into a single piece. This structure makes the assembly process complex and cumbersome, inefficient, and requires a significant amount of time and labor; at the same time, it results in a high injection molding defect rate, is difficult to automate production, and has inconsistent quality. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a wireless slip ring mandrel is proposed, which eliminates the copper ring and wires on the traditional mandrel. It has a simple structure, can be automated, and is efficient, convenient, and produces products with good consistency.

[0004] A slip ring wireless mandrel includes a mandrel body, the surface of which is provided with a plurality of electroplated annular channels arranged closely together and surrounding the outer diameter of the mandrel body, and each electroplated annular channel is provided with an opening leading to the interior of the mandrel body;

[0005] One end face of the mandrel body is provided with countersunk holes of the same number as the openings. Each countersunk hole is covered with an electroplated layer and has an electroplated passage that communicates with one of the openings through the surface wall of the mandrel body.

[0006] Preferably, the main body of the mandrel is in the shape of a ring and is composed of a symmetrical left half and a right half.

[0007] Preferably, the left half and the right half are provided with corresponding matching positioning holes and positioning posts.

[0008] Preferably, the electroplating passage is disposed on the end face of the mandrel body and the inner side wall of the mandrel body.

[0009] Preferably, a first protrusion is provided between two adjacent electroplating rings, and the first protrusion is higher than the surface of the electroplating ring.

[0010] Preferably, a second boss is provided at each end of the electroplating ring, and the second boss is used to fix the bearing.

[0011] Preferably, the mandrel body is made of engineering plastic.

[0012] The wireless slip ring mandrel provided by this utility model has multiple electroplated ring channels on the mandrel body, serving as circuit lines to replace traditional copper rings. Simultaneously, countersunk holes serve as electrical connection ports, and electroplated pathways between the openings in the electroplated ring channels and the countersunk holes on the end face of the mandrel body serve as wires to replace traditional wires. That is, the countersunk holes, openings, electroplated ring channels, and electroplated pathways form a one-to-one connected circuit. Compared with existing technologies, this wireless slip ring mandrel is not only simple in structure, easy to assemble, and highly efficient, but also enables automated production and ensures consistent product quality.

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0020] Provide a wireless slip ring mandrel, such as Figures 1 to 4 As shown, it includes a mandrel body 1, and the surface of the mandrel body is provided with a plurality of electroplating annular channels 2 that are closely arranged together and form around the outer diameter of the mandrel body. Each electroplating annular channel is provided with an opening 3 leading to the interior of the mandrel body.

[0021] One end face of the mandrel body is provided with countersunk holes 4, the same number as the openings. Each countersunk hole is covered with an electroplating layer and is provided with an electroplating passage 5 that connects to an opening through the surface wall of the mandrel body.

[0022] The mandrel body, also known as the rotor, is preferably made of engineering plastic, but is not limited to this. Each electroplating ring on the mandrel body is a loop, and the opening on it serves as the interface end of the current electroplating ring. At the same time, the countersunk hole on the end face of the mandrel body serves as an electrical connection port, providing a circuit connection to the outside of the mandrel body. There is an electroplating passage between the countersunk hole and the opening on the electroplating ring, which is equivalent to a wire. Thus, each countersunk hole, electroplating passage, electroplating ring, and opening forms a one-to-one corresponding and sequentially connected circuit, replacing the copper ring and wire on the traditional mandrel.

[0023] Furthermore, the main body of the mandrel is circular in shape and is composed of symmetrical left and right halves; that is, the two-half structure facilitates laser scanning activation processing. Specifically, the left and right halves are first laser-activated, then the left and right halves are electroplated with rings, passages, openings, and countersunk holes according to a specified route, and finally the left and right halves are joined together by ultrasonic welding. Preferably, the left and right halves are provided with corresponding matching positioning holes 11 and positioning posts 12. The position and number of positioning holes and positioning posts can be flexibly set to facilitate alignment and positioning of the left and right halves and facilitate welding.

[0024] Furthermore, on the mandrel body of the annular structure, electroplating pathways are provided on the end face of the mandrel body and on the inner surface wall of the mandrel body, so that the wiring is not exposed on the surface of the mandrel body.

[0025] Furthermore, a first protrusion 6 is provided between two adjacent electroplating rings. The first protrusion is higher than the surface of the electroplating ring, so that the cross-section of each electroplating ring is a continuous V-shape or U-shape. This structure can prevent interference between adjacent electroplating rings and affect the accuracy of data transmission.

[0026] Furthermore, a second boss 7 is provided at each end of the electroplating ring. The second boss is used to fix the bearing. That is, when the bearing is assembled, the second boss isolates the bearing from the electroplating ring.

[0027] The above is a description of the wireless mandrel of the slip ring of this utility model, which is used to help understand this utility model; however, the implementation of this utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of this utility model shall be considered as equivalent substitutions and shall be included within the protection scope of this utility model.
