[0025] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0027] Combine Figures 1 to 12As shown, a laser output device provided by an embodiment of the present disclosure includes a light guide arm 10 with an optical element installed therein, which is used to concentrate and guide light so that the light is transmitted 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 the signal of the optical element in the light guide arm 10 to the conductive slip ring 20, and the optical element is connected to the electronic connector 30 through a cable to transmit the signal; wherein the electronic connector 30 is provided 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.

[0028] In the laser output device provided by the embodiment of the present disclosure, the electronic connector 30 in the transmission assembly is provided at the junction of 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, so that the cable does not get tangled. In addition, the cooperation between the conductive slip ring 20 and the electronic connector 30 realizes the stable transmission of the optical element signal during the rotation of the light guide arm 10, avoiding the problem of poor or even interrupted signal transmission caused by cable entanglement during the rotation of the traditional light guide arm 10, ensuring the normal operation of the laser output device and improving the stability and reliability of the device.

[0029] In actual application scenarios, such as laser processing equipment, the light guide arm 10 needs to rotate frequently to adjust the output direction of the laser. If the traditional connection method is used, the cable is prone to wear and entanglement during frequent rotation, affecting the processing accuracy and efficiency of the equipment. The structural design in this embodiment can ensure that the signal of the optical element can still be stably transmitted under long-term, high-frequency rotation operations, thereby ensuring the accuracy and quality of laser processing. At the same time, this design is also suitable for medical laser equipment that has extremely high requirements for signal transmission stability, such as laser surgical instruments, and can provide strong guarantees for the safety and accuracy of surgery.

[0030] Optionally, it also includes a bearing seat 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; wherein 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.

[0031] The combination of bearing seat 40, bearing 50, and rotating shaft 60 provides a stable support structure for the rotation of light guide arm 10. The bearing ensures that light guide arm 10 can rotate smoothly along the set axis, reducing shaking and deviation during rotation. The bearing seat 40 fixes the bearing 50, improving the stability of the overall structure. The rotating shaft 60 connects the light guide arm 10 and the bearing 50, realizing the rotation of the light guide arm 10 and enabling the rotor 202 of the conductive slip ring 20 to rotate synchronously with the light guide arm 10, further ensuring the stability of signal transmission.

[0032] In this embodiment, the bearing seat 40 is a structural component used to house and secure the bearing 50. It can restrain the bearing 50 in a specified position and ensure the bearing's rotational accuracy. The bearing 50 is used to ensure the rotation of the light guide arm 10 along a predetermined axis. Preferably, the bearing is a Class 2 precision bearing to ensure that the degree of wobble during rotation meets the requirements for complete transmission of the laser / light through the light guide arm 10. Furthermore, a rotating shaft 60 connects the light guide arm 10 and the bearing 50, enabling the light guide arm 10 to rotate along the predetermined axis.

[0033] High-precision bearings (such as bearings with a precision grade of 2) can effectively reduce the impact of external vibrations and shocks on the rotation accuracy of the light guide arm 10, ensuring that the laser beam can be accurately transmitted to the target position.

[0034] Optionally, the conductive slip ring 20 includes a stator 201 and a rotor 202. The stator 201 is sleeved outside 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 lead-out cables, and the cables of the two are connected to realize signal transmission between the two.

[0035] The stator 201 and rotor 202 of the conductive slip ring 20 are designed to smoothly transmit signals between the fixed portion (stator 201) and the rotating portion (rotor 202) when the light guide arm 10 rotates. This structure prevents cable entanglement 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 that enables the light guide arm 10 to rotate without tangling.

[0036] This embodiment establishes the basic architecture of a laser output device, resolving the cable entanglement issue that typically occurs when the base of a conventional light guide arm 10 rotates. The conductive slip ring 20, in conjunction with the electronic connector 30, ensures stable signal transmission. During operation, this ensures reliable signal transmission between the optical components and external control equipment, improving the stability and reliability of the device.

[0037] Optionally, the cables of the stator 201 are connected to an external control board to transmit signals to the outside. The cables of the rotor 202 are connected to the electronic connector 30 to transmit the signals output by the electronic connector 30 to the stator 201 and the external control board in sequence.

[0038] This connection enables signal exchange between the optical components within light-guide arm 10 and an external control board. The control board can obtain real-time signals from the optical components, such as laser power and wavelength, to precisely control the laser output device, improving the device's intelligence and ease of operation.

[0039] In practical applications, users can monitor the operating status of the optical components within the light guide arm 10 in real time through the user interface on the control panel, adjusting laser parameters as needed. After receiving signals from the optical components, the control panel can quickly respond and adjust the laser's output power, frequency, and other parameters to achieve high-precision results. This connection method also facilitates remote monitoring and fault diagnosis of the equipment, improving maintenance efficiency.

[0040] Optionally, the external control panel may be a power panel or a control panel of a terminal appliance or device.

[0041] This clarifies the various possibilities for connecting an external control board, making the laser output device more adaptable and versatile. Depending on the application scenario and needs, the appropriate control board can be selected to implement different functions, such as providing power control for the device, interacting with terminal devices, or achieving overall device control.

[0042] In laser cosmetic devices, the external control board can serve as the device's control panel, allowing doctors to easily adjust laser parameters such as laser energy and pulse frequency to suit individual patients' skin treatment needs. Furthermore, the control board can work in conjunction with the power board to ensure the device operates within a safe voltage and power range, guaranteeing patient safety. In laser communication equipment, the external control board can serve as the control module for terminal appliances, enabling data transmission and interaction with other communication devices, expanding the application range of laser output devices.

[0043] Optionally, the electronic connector 30 includes: a male head component 301, which is sleeved on the end of the light guide arm 10 and includes a male pin 3012 connected to the cable of the optical element in the light guide arm 10; a female head component 304, which is provided at the end of the rotor 202 of the conductive slip ring 20 and includes 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 to the cable in the conductive slip ring 20 in sequence through the male pin 3012 and the female pin 3042, and then transmitted to the control board through the external cable.

[0044] The design of the male and female connectors 301 and 304 facilitates signal connection between the light guide arm 10 and the conductive slip ring 20. The male and female connectors 3012 and 3042 provide stable and reliable signal transmission, and are easy to install and remove, facilitating equipment maintenance and repair.

[0045] During equipment production and maintenance, male and female pins 3012 and 3042 are frequently plugged and unplugged. To improve their service life and connection stability, gold plating or other surface treatments can be used to reduce contact resistance and signal transmission loss. Furthermore, when designing the male and female pins 3012 and 3042, features can be incorporated to prevent mis-insertion, such as by employing special shapes or positioning mechanisms. This prevents mis-insertion during installation, improving equipment installation efficiency and reliability.

[0046] When the light guide arm 10 rotates, the electronic connector 30 and the rotor 202 of the conductive slip ring 20 rotate accordingly, thereby solving the problem of cable winding when the bottom of the traditional light guide arm 10 rotates.

[0047] Optionally, the male pin 3012 and the female pin 3042 are configured as a shaft-and-hole arrangement. This means that the male pin 3012 has a hole structure, while the female pin 3042 has a shaft structure. When the male pin 3012 and the female pin 3042 are plugged together, the shaft structure of the female pin 3042 fits into the hole structure of the male pin 3012. Of course, the male pin 3012 can also have a shaft structure, while the female pin 3042 has a hole structure. It should be noted that the male (or female) pin is a conductive pin used to connect to a signal transmission cable to transmit signals.

[0048] The pin design, which matches the shaft and hole, ensures good alignment and stability between the male 3012 and female 3042 pins during connection, further improving signal transmission reliability. This structural design is simple, easy to manufacture and assemble, and reduces equipment production costs.

[0049] In actual production, appropriate pin material and dimensions can be selected based on signal transmission requirements and the equipment's operating environment. For high-frequency signal transmission, materials with low dielectric constant and low loss should be used to minimize signal attenuation. Furthermore, rationally designing pin dimensions and tolerances to ensure precise shaft-hole fit ensures a tight connection and facilitates insertion and removal.

[0050] The male pins 3012 and female pins 3042 are used in pairs. The number of male and female pins 3012, 3042 depends on the number of pins on the optical component cables in the light guide arm 10. The pins of the optical component cables in the light guide arm 10 are electrically connected to the male pins 3012 to transmit signals. The signals then pass through the female pins 3042, the rotor 202 of the conductive slip ring 20, and the stator 201 of the conductive slip ring 20, before being transmitted to a control board external to the conductive slip ring 20.

[0051] The number of male 3012 and female 3042 pins is determined based on 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 component.

[0052] In some complex laser output devices, optical components may have numerous pins, transmitting a variety of signals, such as laser power control and temperature monitoring. Therefore, carefully planning the layout and connection of the male 3012 and female 3042 connectors is crucial. Layered or grouped layouts can be used to separate different signal types and reduce interference. During the connection process, ensure that each pin is securely and reliably connected to the male 3012 connector, and conduct rigorous electrical testing to ensure signal transmission quality.

[0053] The male and female components 301 and 304 of the electronic connector 30 are connected via male and female pins 3012 and 3042, which are mated to each other in a axially connected pair. The number of male and female pins 3012 and 3042 depends on the number of pins in the optical component cable in the light guide arm 10. The optical component cable signal is transmitted sequentially via male and female pins 3012 and 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, ensuring precise control of the device. In laser medical cosmetic equipment, stable signal transmission ensures that the device can accurately control laser output parameters according to different treatment needs, improving treatment effectiveness and safety.

[0054] 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 is circumferentially surrounded by a plurality of male pins 3012 .

[0055] The first base 3011 provides a fixing and support structure for the male pin 3012, enabling it to be stably installed on the light guide arm 10. The circumferential mounting method facilitates reasonable pin arrangement according to the layout of optical components and cables, improving space utilization and signal connection convenience.

[0056] The material choice for the first base 3011 also has a certain impact on the device's performance. In addition to commonly used insulating plastic materials, in applications requiring high electromagnetic shielding, materials with electromagnetic shielding properties can be used to construct the first base 3011, such as plastic composite materials with added metal fibers, to reduce the impact of external electromagnetic interference on signal transmission. Furthermore, when designing the first base 3011, heat dissipation structures, such as cooling fins, can be added to reduce the temperature of the pins during operation, thereby improving their reliability and service life.

[0057] Optionally, the first base 3011 is made of an insulating material, such as plastic. The first base 3011 has the functions of insulation and fixedly mounting the male pin 3012.

[0058] Using insulating material to make the first base 3011 effectively prevents short circuits between the male pins 3012, ensuring the safety and stability of signal transmission. Furthermore, insulating materials are lightweight and low-cost, helping to reduce the overall cost of the device.

[0059] When selecting insulating plastic materials, plastics with different properties can be chosen based on the device's operating environment and performance requirements. For example, laser output devices operating in high-temperature environments can use heat-resistant engineering plastics, such as polyetheretherketone (PEEK). Devices operating in humid environments can use plastics with good moisture resistance, such as polycarbonate. Furthermore, flame retardants can be added to the plastic material to improve the fire safety of the first base 3011.

[0060] Optionally, the male connector assembly 301 further includes a fixing ring 303 rigidly connected to the first base 3011, sleeved on the light guide arm 10, and having a clearance fit with the outer circumference of the light guide arm 10. The first base 3011 rotates on the light guide arm 10 along with the fixing ring 303 to adjust the insertion position of the male pin 3012 on the first base 3011.

[0061] Optionally, the fixing ring 303 is cylindrical 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 configured with multiple communication ports, so that the cables of the optical components in the light guide arm 10 can pass through the communication ports and connect to the male pins 3012.

[0062] The design of the fixing ring 303 enables the first base 3011 to rotate on the light guide arm 10, making it easy to adjust the position of the male pin 3012 during installation so that it can better mate with the female pin 3042, thereby improving the flexibility and convenience of installation.

[0063] 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. Furthermore, the retaining ring 303 can be designed with positioning marks or scales to facilitate accurate adjustment of the male pin 3012. 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.

[0064] Optionally, it further includes: a clamping ring 302 , which is covered on the first base 3011 and is used to fix the first base 3011 on the light guide arm 10 .

[0065] The clamping ring 302 can firmly fix the first base 3011 on the light guide arm 10 to prevent the first base 3011 from loosening during the operation of the device, thereby ensuring the connection stability between the male pin 3012 and the female pin 3042, and thus ensuring the reliability of signal transmission.

[0066] The design of the clamping ring 302 can add some anti-slip structures, such as setting anti-slip grooves 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, thereby preventing the clamping ring 302 from loosening. When installing the clamping ring 302, special tools such as a wrench or a screwdriver can be used to ensure that the clamping ring 302 can evenly press the first base 3011 to avoid poor contact or damage to the pins due to uneven compression. In addition, the material of the clamping ring 302 can be selected from a high-strength metal material, such as aluminum alloy or stainless steel, to ensure its reliability during long-term use.

[0067] Optionally, when the first base 3011 is connected to the fixing ring 303, the fixing ring 303 and the first base 3011 can be regarded as a whole, which is embedded in the clamping ring 302. At this time, the inner ring surface of the clamping ring 302 is in contact with the outer peripheral surface of the fixing ring 303.

[0068] Optionally, the outer circumference of the clamping ring 302 is corrugated to increase friction during tightening.

[0069] The corrugated outer surface design greatly increases the friction between the operator's hand and the clamping ring 302 when tightening the clamping ring 302, making the tightening operation more convenient and labor-saving. It also prevents the hand from slipping during the tightening process, thereby improving the safety of the operation.

[0070] In addition to the corrugated design, the outer surface of the clamping ring 302 can also be knurled to further increase friction. The shape and size of the knurling can be optimized based on actual usage requirements. For example, diamond knurling or straight knurling can be used. The knurling depth and spacing 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 rubber coating or anti-slip paint, can be applied to the corrugated or knurled surface to further enhance the anti-slip effect.

[0071] Optionally, the outer circumference of the clamping ring 302 is configured with a handle structure for rotational tightening.

[0072] The design of the handle structure provides the operator with a more convenient force application point, making the operation of tightening the clamping ring 302 easier and more efficient, further improving the convenience of equipment installation and maintenance.

[0073] The shape and size of the handle should conform to ergonomic principles to enhance operator comfort. For example, the handle can be designed with a curved or pistol-grip shape to fit the hand better. The handle should also be of moderate length and thickness. A handle that is too long or too thick can increase difficulty, while a handle that is too short or too thin can impair force application. Furthermore, the handle should be made of a material with a certain degree of elasticity and non-slip properties, such as rubber or silicone, to enhance grip stability.

[0074] 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 female pins 3042 are circumferentially arranged in the second base 3041 .

[0075] The second base 3041 provides a fixing and supporting structure for the female pin 3042, enabling it to be stably mounted on the rotating shaft 60. The circumferential layout of the female pin 3042 facilitates docking with the male pin 3012 of the male connector assembly 301, ensuring the accuracy and stability of signal transmission.

[0076] Similar to the first base 3011, the material selection for the second base 3041 is also crucial. In applications requiring high sealing performance, the second base 3041 can be constructed from a material with excellent sealing properties, such as rubber or silicone. This prevents dust, moisture, and other impurities from entering the connection between the female and male pins 3042, 3012, and potentially affecting signal transmission. Furthermore, the second base 3041 can incorporate positioning features, such as locating pins or slots, to mate with the first base 3011 of the male connector assembly 301, improving the accuracy and efficiency of the connection between the male and female pins 3012, 3042.

[0077] Optionally, the second base 3041 is made of an insulating material, such as plastic. The second base 3041 has the functions of insulation and fixedly mounting the pin mother 3042.

[0078] The second base 3041 is made of insulating material, which prevents short circuits between the female pins 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 device.

[0079] When selecting insulating plastic material for the second base 3041, its chemical resistance should be considered. In industrial applications where chemical reagents may be present, such as laser etching equipment, chemically resistant plastics, such as polytetrafluoroethylene, should be selected to prevent chemical corrosion on the second base 3041 and the female pin 3042, thereby extending the service life of the equipment. Furthermore, reinforcing materials, such as glass fiber, can be added to the insulating plastic to enhance the mechanical strength of the second base 3041.

[0080] Optionally, it further includes: a tightening ring 305 , which is covered on the second base 3041 and is used to fix the second base 3041 to the rotating shaft 60 and the conductive slip ring 20 .

[0081] Optionally, the tightening ring 305 is circumferentially configured with a plurality of first through holes, and the rotor 202 of the conductive slip ring 20 is configured with a plurality of second through holes 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 through holes and the second through holes in sequence, thereby fixing the second base 3041 to the conductive slip ring 20 and the rotating shaft 60.

[0082] 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 female pin 3042 and the male pin 3012, as well as the reliability of the entire signal transmission structure, and preventing loosening during equipment operation.

[0083] The tightening force of the tightening ring 305 should be moderate. Excessive tightening force may cause deformation of the second base 3041 or the rotating shaft 60, affecting device performance; while insufficient tightening force may not guarantee effective securing. The tightening ring 305 can be designed to facilitate tightening with tools, such as a hexagonal nut shape, making it easier for operators to install and remove using tools such as wrenches. Furthermore, to prevent the tightening ring 305 from loosening during long-term use, anti-loosening measures such as spring washers or thread lockers can be employed.

[0084] Optionally, the end of the clamping ring 302 is constructed with an internal thread and the tightening ring 305 is constructed with an external thread. In this way, when the installation and matching of the shaft and the light guide arm 10 are completed, and the male pin 3012 and the female pin 3042 are correctly inserted, the clamping ring 302 and the tightening ring 305 are connected through the internal and external threads, which can not only eliminate the gap in the installation and prevent the male (female) pin from loosening, but also achieve the purpose of further fixing and locking.

[0085] In practical applications, the tightening ring 305 is fixed to the rotor 202 of the conductive slip ring 20 . The tightening ring 302 is screwed together with the tightening ring 305 by rotating the tightening ring 302 to lock and fix the rotor 202 , thereby eliminating gaps during installation.

[0086] 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 through the tightening ring 305 .

[0087] Optionally, the outer circumference of the tightening ring 305 is corrugated or knurled to increase friction during tightening.

[0088] The corrugated outer peripheral surface increases the friction force when the operator tightens the tightening ring 305, making the tightening operation more convenient and labor-saving, avoiding hand slipping during the tightening process, and improving the safety and reliability of the operation.

[0089] Similar to the corrugated outer surface of the compression 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. Furthermore, applying an anti-slip coating, such as polyurethane anti-slip paint, to the corrugated surface further enhances friction. Furthermore, the outer surface of the tightening ring 305 can be designed with markings, such as tightening direction markings or scales, to facilitate accurate operation.

[0090] Optionally, the outer circumference of the tightening ring 305 is configured with a handle structure for rotational tightening.

[0091] Optionally, the rotating shaft 60 is a hollow structure, and the inner annular surface is constructed with an internal thread; the light guide arm 10 is inserted into the rotating shaft 60, and the outer peripheral surface is constructed with an external thread to adapt to the internal thread of the inner annular surface of the rotating shaft 60, so as to fix the rotating shaft 60 and the light guide arm 10 through a threaded connection.

[0092] The threaded connection provides a reliable and stable connection between the rotating shaft 60 and the light guide arm 10. During 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 ensuring that the laser beam is transmitted along a precise path, 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 on a specific location, avoiding processing errors caused by loose connections and ensuring processing quality.

[0093] The hollow structure of the shaft 60 ensures structural strength while effectively saving material and reducing the overall weight of the device. Furthermore, the hollow portion can be used for wiring. Cables for optical components and sensors within the light-guiding arm 10 can be routed within the shaft 60, making the internal layout of the device more compact and neat, reducing the tangled cables within the device, lowering the risk of signal interference caused by crossed cables, and improving the device's electromagnetic compatibility.

[0094] In different application scenarios, equipment may encounter various special environmental conditions. Laser output equipment operating in high-temperature environments can use high-temperature-resistant thread materials and lubricants to ensure that threaded connections maintain good performance even in high temperatures. In humid and corrosive environments, in addition to anti-corrosion treatment of the threads, sealing structures can also be used to seal the threaded connections to prevent the intrusion of moisture and corrosive substances, thereby maintaining the reliability of the threaded connections.

[0095] In this embodiment, the conductive slip ring 20 is mainly relied on. The conductive slip ring 20 has two parts, a rotor 202 and a stator 201. Corresponding wires are led out of the rotor 202 and the stator 201 respectively. The stator 201 is fixed and the rotor 202 rotates. During the rotation, the corresponding wires will not be entangled and the conductivity will not be disturbed. By utilizing this function of the conductive slip ring 20, the traditional light guide arm 10 is improved. When the rotor 202 and the stator 201 of the conductive slip ring 20 move relative to each other, the wobble degree cannot be guaranteed, which will affect the angle at which the laser beam enters the light guide arm 10, thereby causing the laser beam to be cut off after passing through the light guide arm 10. In order to avoid this problem, it is necessary to select a bearing with a high precision grade, that is, a bearing 50. A bearing with a precision grade of 2 is selected, which has a very small wobble degree and can well stabilize the light beam entering the light guide arm 10. The bearing seat 40 limits and fixes the bearing 50, and is rigidly connected to the stator 201 of the conductive slip ring 20. The wires led out of the stator 201 are externally connected to the control board. The rotating shaft 60 cooperates 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 led out of the rotor 202 is connected to the female pin 3042. The female pin 3042 is mounted 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 female pin 3042 and the second base 3041 may rotate or not. When the tightening ring 305 is screwed, the rotating shaft 60 also rotates.

[0096] The male pin 3012 is fixed on the first base 3011, the first base 3011 and the fixing ring 303 are transitionally matched, the fixing ring 303 and the light guide arm 10 are clearance-matched, and are hung on the light guide arm 10. When the light guide arm 10 is lifted, the fixing ring 303 connected to the first base 3011 and the male pin 3012 will be lifted together; the optical component such as the cable of the laser 80 is attached to the outer wall of the light guide arm 10 and connected to the male pin 3012.

[0097] During assembly, insert the light guide arm 10 into the rotating shaft 60. The rotating shaft 60 has an internal thread, and the light guide arm 10 has an external thread. Twist the tightening ring 305 to rotate the rotating shaft 60 so that its thread is fully fitted and tightened. At the same time, insert the male pin 3012 into the female pin 3042 along the guide structure, and the guide can be adjusted by rotating the fixing ring 303. After the insertion is completed, rotate the tightening ring 302 to make it threadedly connected with the tightening ring 305, so that the male pin 3012 and the female pin 3042 are fully fitted and tightened and will not fall off. At the same time, the external thread of the light guide arm 10 and the internal thread of the rotating shaft 60 are locked to prevent them from loosening.

[0098] After assembly is completed, rotating the light guide arm 10 will drive the rotor 202, shaft 60, bearing 50, tightening ring 305, first base 3011, female pin 3042, male pin 3012, second base 3041, fixing ring 303 and clamping ring 302 of the conductive slip ring 20 to rotate together, and all cables are now connected; there will be no flying wires or tangled wires when the light guide arm 10 moves in a circular motion.

[0099] Optionally, the light guide arm 10 includes multiple rotation joints; it also includes: a grating ruler 70, which is arranged at the rotation joint of the light guide arm 10 and is connected to the male pin 3012 through a cable; a control board, which is connected to the conductive slip ring 20 through an external cable to receive the signal transmitted by the female pin 3042; it is configured to detect the rotation posture of the light guide arm 10.

[0100] A grating ruler 70 is installed at the rotating joint of the light guide arm 10, providing real-time and accurate feedback on the rotation angle of the light guide arm 10. This information is transmitted to the control board via the male and female pins 3012 and 3042, as well as the conductive slip ring 20. The control board uses this information to monitor the rotation position of the light guide arm 10 in real time. For example, in laser cosmetic procedures, the light guide arm 10 rotates frequently, and the grating ruler 70 monitors its rotation angle in real time. Based on this data, the control board promptly adjusts laser emission parameters such as power and pulse frequency to ensure that the laser beam is always accurately focused at the set position.

[0101] If the multi-degree-of-freedom light guide arm 10's rotational position is abnormal, it could lead to uncontrolled laser output, potentially causing a safety hazard. A control panel monitors the rotational position of the light guide arm 10 and responds promptly if any abnormality occurs. For example, in laser cosmetic devices, if the light guide arm 10 rotates abnormally, the control panel immediately stops laser 80, preventing accidental laser exposure and effectively ensuring user safety.

[0102] The control panel captures information about the light guide arm's 10 rotational position, allowing it to assess and adjust the device's operating status. If even a slight deviation is detected, the control panel promptly issues instructions to fine-tune relevant components, restoring the arm's 10 to its normal rotational state. This reduces vibration and wear, extends the device's lifespan, and ensures long-term stable operation.

[0103] In this embodiment, the light guide arm 10 includes multiple optical elements such as lenses or reflectors, which can focus, reflect or refract incident light to transmit it to the desired location. A circular grating scale 70 is provided at the rotating joint of the light guide arm 10 to provide real-time feedback on the rotation angle.

[0104] In practical applications, optical components all transmit signals via cables, and the cables attached to the light guide arm 10 are all fixed by cable fixings to prevent the cables from being entangled with the light guide arm 10 .

[0105] Optionally, it also includes: a laser 80, which is provided on the light guide arm 10 and is configured to output laser, and the laser is output through the output port of the light guide arm 10; a control system, which is electrically connected to the laser 80 and the control board respectively; and is configured to receive signals from the control board and control the working state of the laser 80.

[0106] The control system receives signals from the control board regarding the rotational position of the light-guide arm 10 and other indicators, accurately controlling the operating 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 precisely adjusts parameters such as the laser 80's output power, pulse frequency, and beam duration, ensuring that the laser beam accurately reaches the target location.

[0107] Combined with the control board's monitoring of the light guide arm 10's posture, when the light guide arm 10's posture becomes abnormal (such as exceeding a 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, thereby preventing the laser from causing damage to the equipment, operators, or the surrounding environment, thereby greatly improving the safety of the laser output device.

[0108] The control system combines signals from the control board with the control of laser 80, enabling the laser output device to automatically adjust the operation of laser 80 based on the real-time status of light guide arm 10, reducing manual intervention. This precise control of the operating state of laser 80 prevents the laser 80 from operating under inappropriate conditions, reduces wear and tear, and reduces the probability of failure, extending the service life of laser 80 and improving the stability and reliability of the entire laser output device.

[0109] In this embodiment, a circular joint grating ruler 70 is provided at the rotating 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 rotation posture detection. The optional control board for posture detection is connected to the control system for the laser 80, and the control system of the laser 80 is connected to the laser 80. The control board for rotation posture detection is used to detect the rotation posture of the light guide arm 10 in real time, make a judgment and feedback 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.

[0110] In some embodiments, when the light guide arm 10 rotates normally, the control panel for detecting the rotational posture 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 panel for detecting the rotational posture alarms, the control system initiates emergency control, and the laser 80 stops laser output. This resolves the laser output safety issue caused by the excessive degree of freedom of the light guide arm 10.

[0111] For example, during laser freckle removal treatment, the patient lies on the treatment bed while the doctor activates the laser cosmetic device. The multiple rotating joints of the light guide arm 10 rotate flexibly, allowing the laser light emitted by the laser 80 to precisely target the freckles on the patient's face. At this point, the optical scale 70 located at the rotating joints monitors the rotation angle and posture changes of the light guide arm 10 in real time. This information is transmitted via a cable to the male pin 3012, which then transmits it to the control board via the female pin 3042. Based on the received signals, the control board accurately determines the position and motion of the light guide arm 10. When the control board detects that the light guide arm 10 is stably aligned with the freckle area, it 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. After being transmitted through the light guide arm 10, this laser beam acts on the freckle area, breaking down the pigment particles and achieving the freckle removal effect. During treatment, if the rotational 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 the predetermined position, the optical scale 70 quickly detects the change and transmits a signal to the control board. The control panel immediately sends a command to the control system, and the control system suspends the operation of the laser 80 to avoid the laser from accidentally irradiating normal skin tissue and ensure the safety of the treatment.

[0112] For example, during laser hair removal treatment, the area of the patient requiring hair removal is exposed. The doctor adjusts the parameters of the laser cosmetic device and activates it. The rotating joint of the light guide arm 10 begins to operate, driving the laser 80 to the appropriate position. The grating ruler 70 continuously monitors the rotational position of the light guide arm 10 and transmits the signal to the control board via the male pin 3012 and the female pin 3042. Based on the received signal, the control board adjusts the motion trajectory of the light guide arm 10 in real time to ensure that the laser beam emitted by the laser 80 closely adheres to the patient's skin surface and covers the area requiring hair removal. Once the control board confirms the correct position of the light guide arm 10, it sends a signal to the control system, which instructs 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 destroyed the hair follicle tissue, thereby achieving the desired hair removal effect. During the treatment process, if the rotation of the light guide arm 10 deviates, the control board will promptly detect and notify the control system to stop the output of the laser 80 to prevent uneven distribution of laser energy, which may cause skin burns or poor hair removal results.

[0113] For example, during laser skin tightening treatment, the patient cleanses their face and lies on the treatment bed. The laser cosmetic device is activated, and the rotating joint of the light guide arm 10 drives the laser 80 to move across the patient's face. The 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 a cable. Based on the position and posture information of the light guide arm 10, the control board controls the laser 80 to emit a laser beam with a specific energy and pulse width. These laser beams act on the deep layers of the skin, stimulating collagen proliferation and reorganization, achieving the effect of tightening the skin. During the treatment process, if the rotation speed or angle of the light guide arm 10 is abnormal, the control board will immediately transmit a signal to the control system. The control system responds quickly and adjusts the operating state of the laser 80 to avoid excessive concentration or uneven distribution of laser energy, thereby 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 suspends the light output to prevent excessive heat damage to the skin.

[0114] In some embodiments, an artificial intelligence algorithm is used, combined with a three-dimensional model of the patient's skin and treatment needs, to generate an adaptive motion path for the light guide arm 10. Before treatment, a skin scanning device is used to obtain detailed information about the patient's skin, including the distribution and depth of spots and wrinkles. Based on this information, the control system plans the optimal motion trajectory of the light guide arm 10 to ensure that the laser can accurately act on the target area. During the treatment process, the control panel monitors the rotation 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 to ensure the accuracy of the treatment.

[0115] In some embodiments, to further ensure patient safety during laser cosmetic treatments, multiple optical and contact sensors are positioned around the treatment area to monitor in real time the distance and angle between the patient's skin and the light guide arm 10, as well as changes in skin surface temperature. These sensors transmit data to a control panel, which performs a comprehensive analysis based on the rotational position of the light guide arm 10. Upon detecting unexpected skin movement, excessive proximity of the light guide arm 10 to the skin, or an abnormal increase in skin temperature, the control panel immediately sends a signal to the control system, which responds quickly, such as pausing or stopping the laser 80 output and activating a cooling device to cool the treatment area to prevent burns. Furthermore, an eye safety protection system can be installed. By monitoring the position and condition of the patient's eyes, it automatically stops laser output if it detects that the patient is not wearing protective gear or exhibiting abnormal eye movement, preventing laser damage and comprehensively ensuring patient safety.

[0116] In some embodiments, a skin temperature sensor is installed at the output end of the light-guiding arm 10 to monitor the skin temperature in the laser's active area in real time. The sensor transmits the temperature data to a control panel, which analyzes the data based on a preset safe temperature range, the rotational position of the light-guiding 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 suspends laser output based on the control panel's feedback. It also controls the speed and path of the light-guiding arm 10 to increase heat dissipation time and prevent skin damage from overheating.

[0117] In some embodiments, a distance sensor and collision detection device are installed on the light-guiding arm 10. When the light-guiding arm 10 approaches sensitive areas 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 uses this data to determine whether there is a collision risk. If a collision is detected, it immediately sends a signal to the control system, which pauses the movement of the light-guiding arm 10 or adjusts its direction to avoid collisions and ensure patient safety.
