[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] Combination Figures 1 to 12 As shown in the figure, an embodiment of the present disclosure provides a laser output device, including a light guide arm 10 with built-in optical elements for concentrating and guiding light to transmit the light to a set position; it also includes a transmission component, including a conductive slip ring 20 and an electronic connector 30 connected to each other. The electronic connector 30 is configured to transmit signals from the optical elements in the light guide arm 10 to the conductive slip ring 20. The optical elements are connected to the electronic connector 30 via cables to transmit signals; wherein the electronic connector 30 is located at the junction of the light guide arm 10 and the conductive slip ring 20, and the electronic connector 30 rotates synchronously with the light guide arm 10.

[0040] In the laser output device provided in this embodiment, the electronic connector 30 in the transmission component is located at the interface between the light guide arm 10 and the conductive slip ring 20 and rotates synchronously with the light guide arm 10. The rotor 202 of the conductive slip ring 20 rotates synchronously with the rotating shaft 60. When the light guide arm 10 rotates, the electronic connector 30 and the rotor 202 of the conductive slip ring 20 rotate accordingly, preventing cable tangling. Furthermore, the cooperation between the conductive slip ring 20 and the electronic connector 30 ensures stable signal transmission of the optical components during the rotation of the light guide arm 10, avoiding the problem of poor signal transmission or even interruption caused by cable tangling during the rotation of the traditional light guide arm 10. This ensures the normal operation of the laser output device and improves its stability and reliability.

[0041] In practical applications, such as laser processing equipment, the light guide arm 10 needs to rotate frequently to adjust the laser output direction. If a traditional connection method is used, the cables are prone to wear and tangling during frequent rotation, affecting the processing accuracy and efficiency of the equipment. However, the structural design in this embodiment ensures that the signal of the optical components can still be transmitted stably under long-term, high-frequency rotation operations, thereby guaranteeing the accuracy and quality of laser processing. At the same time, this design is also suitable for medical laser equipment with extremely high requirements for signal transmission stability, such as laser surgical instruments, providing strong assurance for the safety and precision of surgery.

[0042] Optionally, it also includes a bearing housing 40, a bearing 50 and a rotating shaft 60 assembled in sequence. The rotating shaft 60 is rigidly connected to the light guide arm 10 and is coaxially arranged. The conductive slip ring 20 is sleeved on the rotating shaft 60, and the rotor 202 of the conductive slip ring 20 rotates synchronously with the rotating shaft 60.

[0043] The combination of bearing housing 40, bearing 50, and rotating shaft 60 provides a stable support structure for the rotation of the light guide arm 10. The bearing ensures that the light guide arm 10 can rotate smoothly along the set axis, reducing swaying and deviation during rotation; bearing housing 40 fixes bearing 50, improving the stability of the overall structure; rotating shaft 60 connects light guide arm 10 and bearing 50, realizing the rotational movement of light guide arm 10, and at the same time enabling the rotor 202 of conductive slip ring 20 to rotate synchronously with light guide arm 10, further ensuring the stability of signal transmission.

[0044] In this embodiment, the bearing seat 40 is a structural component used to place and fix the bearing 50, which can restrict the bearing 50 to a specified position and ensure the bearing rotation accuracy. The bearing 50 is used to ensure the rotation of the light guide arm 10 along a set axis. Preferably, the bearing is a bearing with a precision grade of 2 to ensure that the sway during rotation meets the requirement of complete transmission of laser / light rays through the light guide arm 10. In addition, the rotating shaft 60 is used to connect the light guide arm 10 and the bearing 50 to realize the rotation of the light guide arm 10 along the set axis.

[0045] High-precision bearings (such as bearings with a precision grade of 2) can effectively reduce the impact of external vibrations and impacts on the rotational accuracy of the light guide arm 10, ensuring that the laser beam can be accurately transmitted to the target position.

[0046] Optionally, the conductive slip ring 20 includes a stator 201 and a rotor 202. The stator 201 is sleeved on the outside of the rotor 202, and the rotor 202 can rotate relative to the stator 201. The stator 201 and the rotor 202 are respectively provided with cables and led out, and the cables of the two are connected to realize signal transmission between them.

[0047] The stator 201 and rotor 202 structure design of the conductive slip ring 20 enables smooth signal transmission between the fixed part (stator 201) and the rotating part (rotor 202) when the light guide arm 10 rotates. This structure avoids cable tangling caused by the rotation of the light guide arm 10, while ensuring the continuity and stability of signal transmission. It is one of the core components for achieving cable-free rotation of the light guide arm 10.

[0048] This embodiment constructs the basic architecture of the laser output device, solving the problem of cable tangling when the bottom of the traditional light guide arm 10 rotates. The conductive slip ring 20 cooperates with the electronic connector 30 to achieve stable signal transmission, ensuring reliable signal transmission between optical components and external control equipment during the operation of the laser output device, and improving the stability and reliability of the device operation.

[0049] Optionally, the stator 201's cables are connected to an external control board to transmit signals to the outside. The rotor 202's cables are connected to an electronic connector 30 to transmit the signals output by the electronic connector 30 sequentially to the stator 201 and the external control board.

[0050] This connection method enables signal interaction between the optical components inside the light guide arm 10 and the external control board. The control board can acquire signals from the optical components in real time, such as laser power and wavelength, thereby enabling precise control of the laser output device and improving the intelligence and ease of operation of the equipment.

[0051] In practical applications, users can monitor the working status of the optical components within the light guide arm 10 in real time through the operating interface on the control board, and adjust the laser parameters as needed. After receiving signals from the optical components, the control board can respond quickly, adjusting the laser output power, frequency, etc., to achieve high-precision results. Simultaneously, this connection method facilitates remote monitoring and fault diagnosis of the equipment, improving maintenance efficiency.

[0052] Optionally, the external control board may be a power board or a control panel for terminal electrical appliances or equipment.

[0053] This clarifies the various possibilities for external control boards, making the laser output device more adaptable and versatile. Different control boards can be selected to achieve different functions based on different application scenarios and needs, such as providing power control for the device, exchanging data with terminal electrical appliances, or achieving overall control of the device.

[0054] In laser cosmetic equipment, an external control board serves as the device's control panel, allowing doctors to easily set parameters such as laser energy and pulse frequency to suit the different skin treatment needs of various patients. Simultaneously, the control board can work in conjunction with the power supply board to ensure the equipment operates within safe voltage and power ranges, guaranteeing patient safety. In laser communication equipment, an external control board can function as the control module for terminal electrical appliances, enabling data transmission and interaction with other communication devices, thus expanding the application range of laser output devices.

[0055] Optionally, the electronic connector 30 includes: a male connector assembly 301, sleeved on the end of the light guide arm 10, and including a male pin 3012 connected to the cable of the optical element in the light guide arm 10; and a female connector assembly 304, disposed on the end of the rotor 202 of the conductive slip ring 20, and including a female pin 3042 connected to the cable in the rotor 202. When the male pin 3012 and the female pin 3042 are plugged in, the cable signal of the light guide arm 10 is transmitted sequentially through the male pin 3012 and the female pin 3042 to the cable in the conductive slip ring 20, and then transmitted to the control board through an external cable.

[0056] The design of the male connector 301 and female connector 304 facilitates the signal connection between the light guide arm 10 and the conductive slip ring 20. The insertion method of the male pin 3012 and female pin 3042 ensures stable and reliable signal transmission, and is easy to install and disassemble, facilitating equipment maintenance and repair.

[0057] During the production and maintenance of the equipment, the insertion and removal of male pin 3012 and female pin 3042 are frequent. To improve their service life and connection stability, processes such as gold plating can be used to treat the pin surface, reducing contact resistance and signal transmission loss. Simultaneously, when designing the structure of male pin 3012 and female pin 3042, anti-misinsertion designs can be added, such as using special shapes or positioning structures, to avoid incorrect insertion during installation, thereby improving the installation efficiency and reliability of the equipment.

[0058] When the light guide arm 10 rotates, the rotor 202 of the electronic connector 30 and the conductive slip ring 20 rotates accordingly, thus solving the problem of cable tangling when the bottom of the traditional light guide arm 10 rotates.

[0059] Optionally, the male pin 3012 and female pin 3042 are in a shaft-hole mating configuration. That is, the male pin 3012 has a hole structure, and the female pin 3042 has a shaft structure. When the male pin 3012 and female pin 3042 are connected, the shaft structure of the female pin 3042 is inserted into the hole structure of the male pin 3012. Of course, the male pin 3012 can also be a shaft structure, and the female pin 3042 a hole structure. It should be noted that the male (female) pin is a conductive pin used to connect signal transmission cables to transmit signals.

[0060] The pin design with a shaft-hole fit ensures good alignment and stability between the male pin 3012 and the female pin 3042 during connection, further improving the reliability of signal transmission. This structural design is simple, easy to manufacture and assemble, and reduces the production cost of the equipment.

[0061] In actual production, appropriate pin materials and sizes can be selected based on signal transmission requirements and the equipment's operating environment. For high-frequency signal transmission, pins made of materials with low dielectric constant and low loss should be used to reduce signal attenuation. Simultaneously, the dimensions and tolerances of the pins should be rationally designed to ensure the precision of the shaft-hole fit, guaranteeing both tight pin connections and ease of insertion and removal.

[0062] Male pin 3012 and female pin 3042 are used in pairs. The number of male pin 3012 and female pin 3042 depends on the number of pins on the cables of the optical elements in the light guide arm 10. The pins on the cables of the optical elements in the light guide arm 10 are electrically connected to the male pin 3012 to transmit signals. Then the signals pass sequentially through the female pin 3042, the rotor 202 of the conductive slip ring 20, and the stator 201 of the conductive slip ring 20, and finally the signals are transmitted to the control board connected to the conductive slip ring 20.

[0063] The number of male pins 3012 and female pins 3042 is determined by the number of pins on the optical component cable, ensuring the integrity and accuracy of signal transmission. This one-to-one connection method avoids signal confusion and loss, ensuring that the control board can accurately obtain various information from the optical components.

[0064] In some complex laser output devices, optical components may have numerous pins to transmit various types of signals, such as laser power control signals and temperature monitoring signals. Therefore, the proper planning of the layout and connection method of the male pins 3012 and female pins 3042 is crucial. A layered or grouped layout can be used to separate different types of signals for transmission, reducing interference. Simultaneously, during the connection process, it is essential to ensure a secure and reliable connection between each pin and the male pin 3012, and to conduct rigorous electrical testing to guarantee the quality of signal transmission.

[0065] The male connector 301 and female connector 304 of the electronic connector 30 are connected via male pin 3012 and female pin 3042. Male pin 3012 and female pin 3042 are axially aligned and used in pairs; their number depends on the number of pins on the optical element cables in the light guide arm 10. The cable signals from the optical elements are sequentially transmitted via male pin 3012 and female pin 3042 to the conductive slip ring 20, and then to the control board. This ensures stable signal transmission during the rotation of the light guide arm 10, providing a guarantee for precise control of the equipment. In laser medical aesthetic equipment, stable signal transmission ensures that the equipment can accurately control laser output parameters according to different treatment needs, improving treatment effectiveness and safety.

[0066] Optionally, the male connector assembly 301 further includes: a first base 3011, which is sleeved on the end of the light guide arm 10 and has a plurality of male pins 3012 inserted around it in the circumferential direction.

[0067] The first base 3011 provides a fixing and support structure for the male pin 3012, enabling it to be stably mounted on the light guide arm 10. The circumferential mounting method facilitates reasonable pin arrangement according to the layout of optical component cables, improving space utilization and signal connection convenience.

[0068] The material selection for the first base 3011 also has a certain impact on the performance of the equipment. Besides commonly used insulating plastic materials, in applications with high electromagnetic shielding requirements, materials with electromagnetic shielding capabilities can be used to make the first base 3011, such as plastic composite materials with added metal fibers, to reduce the impact of external electromagnetic interference on signal transmission. Simultaneously, when designing the structure of the first base 3011, heat dissipation structures, such as heat sinks, can be added to reduce the temperature of the pins during operation, thereby improving their reliability and service life.

[0069] Optionally, the first base 3011 is made of an insulating material, such as plastic. The first base 3011 serves to insulate and securely mount the male pin 3012.

[0070] The first base 3011 is made of insulating material, which effectively avoids short circuits between the male pins 3012, ensuring the safety and stability of signal transmission. At the same time, the insulating material also has advantages such as light weight and low cost, which helps to reduce the overall cost of the equipment.

[0071] When selecting insulating plastic materials, plastics with different properties can be chosen based on the operating environment and performance requirements of the equipment. For example, for laser output equipment operating in high-temperature environments, high-temperature resistant engineering plastics, such as polyetheretherketone (PEEK), can be selected; for equipment operating in humid environments, plastics with good moisture-proof properties, such as polycarbonate, can be selected. Furthermore, flame retardants can be added to the plastic material to improve the fire safety of the first base 3011.

[0072] Optionally, the male connector assembly 301 further includes a retaining ring 303, which is rigidly connected to the first base 3011, sleeved on the light guide arm 10, and has a clearance fit with the outer peripheral surface of the light guide arm 10. The first base 3011 rotates with the retaining ring 303 on the light guide arm 10 to adjust the insertion position of the male pin 3012 on the first base 3011.

[0073] Optionally, the fixing ring 303 is columnar and hollow inside, and the first base 3011 is embedded in the fixing ring 303 and rigidly connected to the fixing ring 303. Optionally, the bottom wall of the fixing ring 303 is constructed with multiple communication ports so that the cables of the optical elements in the light guide arm 10 can pass through the communication ports and connect to the male pin 3012.

[0074] The design of the retaining ring 303 allows the first base 3011 to rotate on the light guide arm 10, which facilitates the adjustment of the position of the male pin 3012 during installation, so that it can better align with the female pin 3042, thereby improving the flexibility and convenience of installation.

[0075] To ensure smoother rotation of the retaining ring 303 on the light guide arm 10, a lubricant, such as silicone oil, can be added to the contact surface between the retaining ring 303 and the light guide arm 10. Additionally, the structural design of the retaining ring 303 can incorporate positioning marks or graduations to facilitate accurate adjustment of the male pin 3012 by the operator. Furthermore, the retaining ring 303 can be made of a material with a certain degree of elasticity and wear resistance, such as rubber or nylon, to reduce wear on the surface of the light guide arm 10 while ensuring a tight connection between the retaining ring 303 and the light guide arm 10.

[0076] Optionally, it also includes: a clamping ring 302, which covers the first base 3011 and is used to fix the first base 3011 to the light guide arm 10.

[0077] The clamping ring 302 can firmly fix the first base 3011 on the light guide arm 10, prevent the first base 3011 from loosening during the operation of the device, ensure the connection stability of the male pin 3012 and the female pin 3042, and thus ensure the reliability of signal transmission.

[0078] The clamping ring 302 can be designed with additional anti-slip structures, such as anti-slip textures or rubber pads on its inner wall, to increase the friction between the clamping ring 302 and the first base 3011 and the light guide arm 10, preventing the clamping ring 302 from loosening. When installing the clamping ring 302, specialized tools, such as wrenches or screwdrivers, can be used to ensure that the clamping ring 302 can evenly clamp the first base 3011, avoiding poor contact or pin damage due to uneven clamping. Furthermore, the clamping ring 302 can be made of high-strength metal materials, such as aluminum alloy or stainless steel, to ensure its reliability during long-term use.

[0079] Optionally, when the first base 3011 is connected to the fixing ring 303, the fixing ring 303 and the first base 3011 can be considered as a whole, and are integrally embedded in the clamping ring 302. In this case, the inner ring surface of the clamping ring 302 abuts against the outer peripheral surface of the fixing ring 303.

[0080] Optionally, the outer peripheral surface of the clamping ring 302 is corrugated to increase friction when tightened.

[0081] The corrugated outer surface design greatly increases the friction between the operator's hand and the clamping ring 302 when tightening, making the tightening operation more convenient and labor-saving, while also preventing the hand from slipping during the tightening process and improving the safety of the operation.

[0082] In addition to the corrugated design, a knurling process can be applied to the outer circumference of the clamping ring 302 to further increase friction. The shape and size of the knurling can be optimized according to actual usage requirements, such as using diamond knurling or straight knurling. The depth and spacing of the knurling should be moderate to ensure sufficient friction without affecting the appearance and strength of the clamping ring 302. Furthermore, an anti-slip coating, such as a rubber coating or anti-slip paint, can be applied to the corrugated or knurled surface to further improve the anti-slip effect.

[0083] Optionally, the outer peripheral surface of the clamping ring 302 is provided with a handle structure for rotational tightening.

[0084] The handle design provides operators with a more convenient point of force application, making the tightening of the clamping ring 302 easier and more efficient, and further improving the convenience of equipment installation and maintenance.

[0085] The shape and size of the handle should conform to ergonomic principles to improve operator comfort. For example, the handle can be designed in an arc or pistol grip shape to better fit the hand. The length and thickness of the handle should also be moderate; too long or too thick will increase the difficulty of operation, while too short or too thin will affect the application of force. In addition, the handle material can be selected to have a certain degree of elasticity and anti-slip properties, such as rubber or silicone, to improve the operator's grip stability.

[0086] Optionally, the female connector assembly 304 further includes: a second base 3041, which is sleeved on the end of the rotating shaft 60 and abuts against the end of the conductive slip ring 20; wherein a plurality of pin nuts 3042 are arranged circumferentially around the second base 3041.

[0087] The second base 3041 provides a fixing and support structure for the pin nut 3042, enabling it to be stably mounted on the rotating shaft 60. The circumferential layout of the pin nut 3042 facilitates mating with the pin male 3012 of the male connector assembly 301, ensuring the accuracy and stability of signal transmission.

[0088] Similar to the first base 3011, the material selection for the second base 3041 is also crucial. In applications requiring high sealing performance, materials with excellent sealing properties, such as rubber or silicone, can be used to make the second base 3041 to prevent dust, moisture, and other impurities from entering the connection between the pin nut 3042 and the pin nut 3012, thus affecting signal transmission. Furthermore, the structural design of the second base 3041 can incorporate positioning structures, such as positioning pins or grooves, to cooperate with the first base 3011 of the male connector assembly 301, improving the accuracy and efficiency of the mating between the pin nut 3012 and the pin nut 3042.

[0089] Optionally, the second base 3041 is made of an insulating material, such as plastic. The second base 3041 serves to insulate and securely mount the pin nut 3042.

[0090] The second base 3041 is made of insulating material, which avoids short circuits between the pin nuts 3042 and ensures the safety and stability of signal transmission. At the same time, the use of insulating material can also reduce the overall weight and cost of the equipment.

[0091] When selecting the insulating plastic material for the second base 3041, its chemical resistance must be considered. In industrial applications where contact with chemical reagents is possible, such as laser etching equipment, plastics with chemical resistance, such as polytetrafluoroethylene (PTFE), should be selected to prevent corrosion of the second base 3041 and the pin nut 3042, thus extending the equipment's service life. Furthermore, reinforcing materials, such as glass fiber, can be added to the insulating plastic to improve the mechanical strength of the second base 3041.

[0092] Optionally, it also includes: a tightening ring 305, which covers the second base 3041 and is used to fix the second base 3041 to the rotating shaft 60 and the conductive slip ring 20.

[0093] Optionally, the tightening ring 305 has multiple first through holes in its circumferential direction, and the rotor 202 of the conductive slip ring 20 has multiple second through holes that are adapted to the first through holes. The tightening ring 305 and the rotor 202 of the conductive slip ring 20 are fixedly connected by fasteners passing through the first and second through holes in sequence, thereby fixing the second base 3041 to the conductive slip ring 20 and the rotating shaft 60.

[0094] The tightening ring 305 can firmly fix the second base 3041 on the rotating shaft 60 and the conductive slip ring 20, ensuring the stability of the connection between the pin female 3042 and the pin male 3012, as well as the reliability of the entire signal transmission structure, and preventing loosening during equipment operation.

[0095] The tightening force of the tightening ring 305 should be moderate. Excessive force may deform the second base 3041 or the rotating shaft 60, affecting the equipment's performance; insufficient force will not guarantee a secure hold. The tightening ring 305 can be designed for easy tightening with tools, such as a hexagonal nut shape, allowing operators to easily install and remove it using wrenches or other tools. Furthermore, to prevent the tightening ring 305 from loosening during long-term use, anti-loosening measures can be taken, such as using spring washers or thread-locking compound.

[0096] Optionally, the end of the clamping ring 302 is provided with an internal thread, and the tightening ring 305 is provided with an external thread. In this way, after the shaft and the light guide arm 10 are installed and fitted, and after the male pin 3012 and the female pin 3042 are correctly inserted, the clamping ring 302 and the tightening ring 305 are connected by the internal and external threads. This not only eliminates the gap in the installation fit and prevents the male (female) pin from loosening, but also achieves the purpose of further fixing and locking.

[0097] In practical applications, the tightening ring 305 is fixed to the rotor 202 of the conductive slip ring 20. By rotating the clamping ring 302, it is threadedly connected to the tightening ring 305 to lock and fix it, eliminating gaps during installation.

[0098] In this embodiment, the tightening ring 305 is rigidly connected to the rotor 202 of the conductive slip ring 20, and the rotor 202 is rigidly connected to the rotating shaft 60. The second base 3041 is directly or indirectly fixed to the rotating shaft 60 and the conductive slip ring 20 by the tightening ring 305.

[0099] Optionally, the outer peripheral surface of the tightening ring 305 may be corrugated or knurled to increase friction during tightening.

[0100] The corrugated outer surface increases the friction when the operator tightens the tightening ring 305, making the tightening operation more convenient and labor-saving, avoiding hand slippage during the tightening process, and improving the safety and reliability of the operation.

[0101] Similar to the corrugated outer surface of the pressure ring 302, the corrugated design of the tightening ring 305 can also be optimized. The shape, depth, and spacing of the corrugations can be adjusted according to actual usage to achieve optimal anti-slip performance. Simultaneously, applying an anti-slip coating, such as polyurethane anti-slip paint, to the corrugated surface further enhances friction. Furthermore, markings, such as tightening direction indicators or graduations, can be designed on the outer surface of the tightening ring 305 to facilitate accurate operation by the operator.

[0102] Optionally, the outer circumferential surface of the tightening ring 305 is provided with a handle structure for rotational tightening.

[0103] Optionally, the rotating shaft 60 has a hollow structure and an internal thread on its inner ring surface; the light guide arm 10 is inserted into the rotating shaft 60 and has an external thread on its outer circumferential surface to match the internal thread on the inner ring surface of the rotating shaft 60, so as to fix the rotating shaft 60 and the light guide arm 10 by threaded connection.

[0104] The threaded connection provides a reliable and stable connection between the rotating shaft 60 and the light guide arm 10. During the operation of the laser output device, the light guide arm 10 needs to rotate continuously. The friction and tightening force generated by the threaded connection effectively prevent relative displacement or loosening between the rotating shaft 60 and the light guide arm 10. This ensures that the light guide arm 10 maintains a stable posture during rotation, thereby guaranteeing that the laser beam is transmitted along a precise path and improving the stability and accuracy of the laser output. In high-precision laser output devices, a stable connection ensures that the laser beam is always focused at a specific position, avoiding processing errors caused by loose connections and ensuring processing quality.

[0105] The rotating shaft 60 adopts a hollow structure, which effectively saves materials and reduces the overall weight of the equipment while ensuring structural strength. In addition, the hollow part can also be used for wiring, arranging the cables of optical components and sensor cables inside the light guide arm 10 inside the rotating shaft 60, making the internal layout of the equipment more compact and neat, reducing the messy tangling of cables inside the equipment, reducing the risk of signal interference caused by cable crossings, and improving the electromagnetic compatibility of the equipment.

[0106] In different application scenarios, equipment may face various special environmental conditions. For laser output equipment operating in high-temperature environments, high-temperature resistant thread materials and lubricants can be used to ensure that the threaded connection maintains good performance even at high temperatures. In humid and corrosive environments, in addition to anti-corrosion treatment of the threads, a sealing structure can be used to seal the threaded connection, preventing the intrusion of moisture and corrosive substances and protecting the reliability of the threaded connection.

[0107] In this embodiment, the main component relies on a conductive slip ring 20, which consists of a rotor 202 and a stator 201. Corresponding wires are led out from the rotor 202 and stator 201 respectively. The stator 201 is fixed, while the rotor 202 rotates. During rotation, the corresponding wires do not become entangled, and the conductivity is not affected. This function of the conductive slip ring 20 improves upon the traditional light guide arm 10. When the rotor 202 and stator 201 of the conductive slip ring 20 move relative to each other, the degree of wobbling cannot be guaranteed, affecting the angle at which the laser beam enters the light guide arm 10, thus causing the laser beam to be cut off after passing through the light guide arm 10. To avoid this problem, a high-precision bearing, namely bearing 50, needs to be selected. A bearing with a precision grade of 2 is selected, which has very small wobbling and can effectively stabilize the laser beam. The bearing housing 40 limits and fixes the bearing 50, and is rigidly connected to the stator 201 of the conductive slip ring 20. The wires leading out from the stator 201 are connected to the external control board. The rotating shaft 60 is fitted with the shaft hole of the bearing 50, and is rigidly connected to the rotor 202 of the conductive slip ring 20. When the bearing 50 rotates, the rotating shaft 60 and the rotor 202 rotate together. The cable leading out from the rotor 202 is connected to the pin nut 3042. The pin nut 3042 is installed on the second base 3041. The second base 3041 and the tightening ring 305 are rigidly connected to the rotor 202 of the conductive slip ring 20. When the bearing 50 rotates, the rotating shaft 60, the rotor 202 of the conductive slip ring 20, and the tightening ring 305 rotate together, while the pin nut 3042 and the second base 3041 may or may not rotate. When the tightening ring 305 is tightened, the rotating shaft 60 will also rotate.

[0108] The male pin 3012 is fixed on the first base 3011. The first base 3011 is transitionally fitted with the fixing ring 303. The fixing ring 303 is clearance-fitted with the light guide arm 10 and is hung on the light guide arm 10. When the light guide arm 10 is lifted, the fixing ring 303, the first base 3011, and the male pin 3012 will be lifted together. The cable of the optical component, such as the laser 80, is attached to the outer wall of the light guide arm 10 and connected to the male pin 3012.

[0109] During assembly, insert the light guide arm 10 into the rotating shaft 60. The rotating shaft 60 has internal threads, and the light guide arm 10 has external threads. Tighten the tightening ring 305 to rotate the rotating shaft 60, ensuring that its threads are fully engaged and tight. At the same time, insert the male pin 3012 into the female pin 3042 along the guide structure. The guide can be adjusted by rotating the fixing ring 303. After insertion, rotate the clamping ring 302 to connect it with the threaded connection of the tightening ring 305, thereby ensuring that the male pin 3012 and the female pin 3042 are fully engaged and tight, preventing them from falling off. This also locks the engagement between the external threads of the light guide arm 10 and the internal threads of the rotating shaft 60, preventing them from loosening.

[0110] After assembly, rotating the light guide arm 10 will cause the rotor 202, shaft 60, bearing 50, tightening ring 305, first base 3011, pin 3042, pin 3012, second base 3041, fixing ring 303 and clamping ring 302 of the conductive slip ring 20 to rotate together, and the cables will be fully connected; there will be no flying wires or winding wires when the light guide arm 10 moves in a circular motion.

[0111] Optionally, the light guide arm 10 includes multiple rotation joints; it also includes: a grating ruler 70, located at the rotation joint of the light guide arm 10 and connected to the male pin 3012 via a cable; a control board, connected to the conductive slip ring 20 via an external cable to receive signals transmitted by the female pin 3042; and is configured to detect the rotational attitude of the light guide arm 10.

[0112] A grating ruler 70 is installed at the rotating joint of the light guide arm 10, which can provide real-time and accurate feedback on the rotation angle information of the light guide arm 10. This information is transmitted to the control board via the male pin 3012, the female pin 3042, and the conductive slip ring 20. The control board uses this information to monitor the rotation posture of the light guide arm 10 in real time. Taking laser beauty treatment as an example, the light guide arm 10 needs to rotate frequently. The grating ruler 70 can monitor its rotation angle in real time. The control board adjusts the laser emission parameters, such as power and pulse frequency, in a timely manner based on this data to ensure that the laser beam is always accurately focused at the set position.

[0113] If the rotational posture of the multi-degree-of-freedom light guide arm 10 is abnormal, it may lead to uncontrolled laser output direction and cause safety accidents. The control board detects the rotational posture of the light guide arm 10, and can react quickly if the posture becomes abnormal. For example, in laser beauty equipment, when the light guide arm 10 rotates abnormally, the control board immediately controls the laser 80 to stop outputting laser light, preventing accidental laser irradiation of the human body and effectively ensuring the user's safety.

[0114] The rotational attitude information of the light guide arm 10 acquired by the control board can be used to evaluate and adjust the equipment's operating status. If a slight deviation in the rotation of the light guide arm 10 is detected, the control board can promptly issue instructions to fine-tune the relevant components, restoring the light guide arm 10 to its normal rotational state, reducing equipment vibration and wear, extending the equipment's service life, and ensuring long-term stable operation of the equipment.

[0115] In this embodiment, the light guide arm 10 includes multiple optical elements such as lenses or mirrors, which can focus, reflect, or refract incident light to transmit the light to the desired location. A circular grating ruler 70 is provided at the rotation joint of the light guide arm 10 to provide real-time feedback on the rotation angle.

[0116] In practical applications, optical components transmit signals via cables. The cables attached to the light guide arm 10 are secured with cable fasteners to prevent them from getting tangled in the light guide arm 10.

[0117] Optionally, it also includes: a laser 80 disposed on the light guide arm 10 and configured to output laser light, the laser light being output through the output port of the light guide arm 10; and a control system electrically connected to the laser 80 and the control board respectively; configured to receive signals from the control board and control the working state of the laser 80.

[0118] The control system receives signals from the control board regarding the rotational attitude of the light guide arm 10, and can precisely control the working state of the laser 80 based on the actual state of the light guide arm 10. When the light guide arm 10 rotates to a specific position, the control system can accurately adjust parameters such as the output power, pulse frequency, and emission time of the laser 80, thereby ensuring that the laser can accurately act on the target position.

[0119] By combining the control board to monitor the posture of the light guide arm 10, when the posture of the light guide arm 10 becomes abnormal (such as exceeding the preset safety range), the control system can respond quickly, shut down the laser 80 in time or adjust its output power to a safe level, so as to avoid damage to the equipment, operators or the surrounding environment by the laser, and greatly improve the safety of laser output equipment.

[0120] The control system combines the signals from the control board with the control of the laser 80, enabling the laser output device to automatically adjust the operation of the laser 80 based on the real-time status of the light guide arm 10, reducing manual intervention. Precise control of the laser 80's operating status prevents it from operating under inappropriate conditions, reducing laser 80 wear and tear and the probability of malfunctions, extending its lifespan, and also contributing to improved stability and reliability of the entire laser output device.

[0121] In this embodiment, a circular joint grating ruler 70 is provided at the rotation joint of the light guide arm 10. The cable of the grating ruler 70 is attached to the outer wall of the light guide arm 10 and connected to the male pin 3012. The female pin 3042 is connected to the control board for rotational attitude detection. Optionally, the attitude detection control board is connected to the control system for the laser 80. The control system for the laser 80 is connected to the laser 80. The rotational attitude detection control board is used to detect the rotational attitude of the light guide arm 10 in real time, make a judgment, and feed back to the control system of the laser 80. The control system of the laser 80 controls the state of the laser 80 and controls whether the laser 80 outputs laser light.

[0122] In some embodiments, when the light guide arm 10 rotates normally, the control board used for rotation attitude detection does not alarm, the control system operates normally, and the laser 80 operates normally. In some embodiments, when the light guide arm 10 rotates abnormally, the control board used for rotation attitude detection alarms, the control system takes emergency action, and the laser 80 stops laser output. This solves the laser output safety problem caused by excessive freedom of the light guide arm 10.

[0123] For example, during laser freckle removal treatment, the patient lies on the treatment bed, and the doctor turns on the laser cosmetic equipment. Multiple rotating joints of the light guide arm 10 rotate flexibly, allowing the laser emitted by the laser 80 to be precisely aimed at the freckled areas on the patient's face. At this time, the grating ruler 70, located at the rotating joints, monitors the rotation angle and posture changes of the light guide arm 10 in real time and transmits this information via cable to the male pin 3012, and then via the female pin 3042 to the control board. Based on the received signals, the control board accurately determines the position and movement state of the light guide arm 10. When it detects that the light guide arm 10 is stably aligned with the freckled area, the control board sends a signal to the control system. The control system then controls the laser 80 to emit a laser beam with a specific wavelength, energy, and pulse frequency. These laser beams, after being transmitted through the light guide arm 10, act on the freckled area, breaking down pigment particles to achieve the freckle removal effect. During the treatment, if the rotation posture of the light guide arm 10 becomes abnormal, such as due to slight movement of the patient causing the light guide arm 10 to deviate from its predetermined position, the grating ruler 70 will quickly detect the change and transmit a signal to the control board. The control panel immediately sends a command to the control system, which then pauses the operation of laser 80 to prevent the laser from accidentally irradiating normal skin tissue and ensure the safety of the treatment.

[0124] For example, in laser hair removal treatment, the area where the patient needs hair removal is exposed. After the doctor adjusts the parameters of the laser beauty equipment, the device is started. The rotational joint of the light guide arm 10 begins to work, moving the laser 80 to the appropriate position. The grating ruler 70 continuously monitors the rotational posture of the light guide arm 10 and transmits the signal to the control board through the male pin 3012 and female pin 3042. Based on the received signal, the control board adjusts the movement trajectory of the light guide arm 10 in real time to ensure that the laser beam emitted by the laser 80 can closely adhere to the patient's skin surface and cover the area requiring hair removal. Once the control board confirms that the position of the light guide arm 10 is accurate, it sends a signal to the control system, which then controls the laser 80 to emit high-energy laser pulses. These laser pulses are absorbed by the melanin in the hair follicles, converted into heat energy, and destroy the hair follicle tissue, thereby achieving the purpose of hair removal. During the treatment, if the rotation of the light guide arm 10 deviates, the control board will detect it in time and notify the control system to stop the output of the laser 80 to prevent uneven distribution of laser energy from causing skin burns or poor hair removal results.

[0125] For example, during laser skin tightening treatment, the patient lies on the treatment bed after facial cleansing. The laser beauty device is activated, and the rotating joint of the light guide arm 10 moves the laser 80 across the patient's face. A grating ruler 70 monitors the rotational posture of the light guide arm 10 in real time and transmits the data to the control board via cable. Based on the position and posture information of the light guide arm 10, the control board controls the laser 80 to emit laser beams with specific energy and pulse width. These laser beams act on the deep layers of the skin, stimulating collagen proliferation and remodeling, achieving a skin tightening effect. During treatment, if the rotational speed or angle of the light guide arm 10 becomes abnormal, the control board immediately transmits a signal to the control system. The control system responds quickly, adjusting the working state of the laser 80 to avoid excessive concentration or uneven distribution of laser energy, ensuring the safety and effectiveness of the treatment. For example, if the light guide arm 10 stays in a certain area for too long, the control board detects the abnormality, and the control system automatically reduces the power of the laser 80 or pauses light emission to prevent excessive heat damage to the skin.

[0126] In some embodiments, artificial intelligence algorithms are used to generate an adaptive motion path for the light guide arm 10, combining a 3D model of the patient's skin and treatment needs. Before treatment, a skin scanning device is used to obtain detailed information about the patient's skin, including the distribution and depth of pigmentation and wrinkles. Based on this information, the control system plans the optimal motion trajectory of the light guide arm 10, ensuring that the laser can accurately target the area. During treatment, the control panel monitors the rotational posture of the light guide arm 10 in real time and feeds the data back to the control system. If the patient's body position moves slightly, the control system can automatically adjust the motion path of the light guide arm 10 based on the feedback information, ensuring the accuracy of the treatment.

[0127] In some embodiments, to further ensure patient safety during laser cosmetic treatment, multiple optical and contact sensors are installed around the treatment area to monitor the distance and angle between the patient's skin and the light guide arm 10, as well as changes in skin surface temperature in real time. These sensors transmit data to a control board, which performs comprehensive analysis based on the rotational posture information of the light guide arm 10. When unexpected movement of the patient's skin, excessive closeness between the light guide arm 10 and the skin, or abnormal increase in skin temperature is detected, the control board immediately sends a signal to the control system. The control system reacts rapidly, such as pausing or stopping the laser 80 output, and simultaneously activating a cooling device to cool the treatment area and prevent skin burns. Furthermore, an eye safety protection system can be equipped. By detecting the position and state of the patient's eyes, it automatically stops laser output when the patient's eyes are not properly protected or when there are abnormal eye movements, preventing laser damage to the eyes and comprehensively ensuring patient safety.

[0128] In some embodiments, a skin temperature sensor is installed at the output end of the light guide arm 10 to monitor the skin temperature in the laser-affected area in real time. The sensor transmits the temperature data to the control board, which analyzes the temperature data based on a preset safe temperature range, the rotational posture of the light guide arm 10, and the operating status of the laser 80. If the skin temperature exceeds the safe range, the control system automatically adjusts the output power of the laser 80 or pauses laser output based on feedback from the control board. Simultaneously, it controls the movement speed and path of the light guide arm 10 to increase heat dissipation time and prevent skin damage due to overheating.

[0129] In some embodiments, a distance sensor and a collision detection device are installed on the light guide arm 10. When the light guide arm 10 approaches a sensitive part of the patient's body or other obstacles during movement, the distance sensor monitors the distance in real time and transmits the data to the control board. The control board determines whether there is a collision risk based on this data. If a collision hazard is detected, it immediately sends a signal to the control system, which then pauses the movement of the light guide arm 10 or adjusts its direction of movement to avoid a collision and ensure the patient's safety.
