However, LED streetlights will experience light decay and damage during long-term use, requiring regular maintenance. Traditional maintenance methods for LED streetlights rely on manual climbing or the use of aerial work platforms, which are inefficient and pose safety hazards. To address this, a robotic arm for LED streetlight maintenance has been developed. Equipped with high-definition visual recognition devices and sensor groups, it can accurately capture the location of streetlight faults and determine the degree of damage. Then, it can simulate manual actions to complete delicate operations such as screw removal, light source replacement, and circuit testing, thereby improving maintenance efficiency and fault handling accuracy.

[0003] A search revealed Chinese patent publication number CN205773186U, which discloses an intelligent LED street light maintenance robotic arm.

The control device can control the movements of other components, and the identification device can identify various parts of the LED street light, enabling automated maintenance. This utility model has a reasonable and convenient structure, improving maintenance efficiency, reducing workload, and achieving automated maintenance. However, in practical use, although the end effector structure within the LED street light maintenance robotic arm has limitations, resulting in insufficient tool compatibility, and because street light maintenance involves multiple operations, the end effector's specialized design makes it impossible to quickly change tool heads, or the replacement process is cumbersome, reducing efficiency.

The elastic buckle is then slid into the slot to complete the initial fixation. The bolt is then passed through the through hole of the maintenance arm and screwed into the threaded grooves of the two guide blocks. Finally, a nut is tightened at the bottom to enhance the connection stability and achieve a stable connection between the maintenance arm and the connecting block, which facilitates subsequent operations.

[0016] The above technical solution involves using a servo motor to drive a fixed gear to rotate, and then utilizing the meshing connection between the two gears to make the bidirectional gear rotate.

[0017] As a further description of the above technical solution: The outer wall of the maintenance arm has two hidden grooves, and the left side of the inner wall of the movable groove has two elastic protective plates fixedly connected.

[0018] The above technical solution involves concealing the top of the bolt and the nut through a hidden groove, allowing the robotic arm to maintain surface lubrication, while the elastic protective plate prevents impurities from entering the moving groove.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 2 , Figure 4 and Figure 6 This utility model provides an embodiment of a robotic arm for LED street light maintenance, comprising a maintenance arm 1 and a connecting block 2. The maintenance arm 1 serves as the main component for calibration by the control device. A fixing mechanism 3 is provided at the left end of the maintenance arm 1, which is used to quickly fix the maintenance arm 1 and the connecting block 2. An execution connector 4 is fixedly connected to the left end of the connecting block 2, which is used to install a stepper for tool clamping. A moving groove 5 is provided at the left end of the execution connector 4, which provides moving space for the clamping component. A clamping mechanism 6 is provided on the inner wall of the moving groove 5, which clamps the workpiece. A turning mechanism 7 is provided at the left end of the connecting block 2, which is used to control the execution connector 4 to rotate around its own central axis. A temperature compensation mechanism 8 is provided on the outer wall of the maintenance arm 1, which is used to adjust the temperature of the maintenance arm 1 itself. The fixing mechanism 3 includes a rubber pad 301, which is used to reduce vibration. The left end of the rubber pad 301 is fixedly connected to the right end of the connecting block 2. Two slots 302 are opened on the right end of the outer wall of the connecting block 2. The inner walls of the two slots 302 are slidably connected with elastic buckles 303. The slots 302 and the elastic buckles 303 can be engaged and fixed. Guide blocks 304 are fixedly connected to the upper and lower sides of the right end of the connecting block 2. Two guide grooves 305 are opened on the left end of the maintenance arm 1. The guide blocks 304 can slide into the guide grooves 305. The outer walls of the two guide blocks 304 are provided with threaded grooves 306. The inner walls of the two threaded grooves 306 are threadedly connected with the same bolt 307. The bolt 307 passes through the threaded grooves 306 and through the left end of the outer wall of the maintenance arm 1. The bottom end of the outer wall of the bolt 307 is threadedly connected with a nut 308. A reinforcing component 309 is provided on the right end of the connecting block 2. The reinforcing component 309 is used to reinforce the connection. The reinforcement component 309 includes an electromagnetic chuck 3091. The left end of the electromagnetic chuck 3091 is fixedly connected to the middle of the right end of the connecting block 2. The middle of the left end of the maintenance arm 1 is provided with a mounting groove 3092. An iron fixing plate 3093 is fixedly connected to the inner wall of the mounting groove 3092. The electromagnetic chuck 3091 and the iron fixing plate 3093 can generate magnetic attraction. Specifically, align the two guide blocks 304 on the right end of the connecting block 2 with the two guide grooves 305 on the left end of the maintenance arm 1, and push the connecting block 2 horizontally along the guide grooves 305. The rubber pad 301 fits against the left end of the maintenance arm 1, and the elastic deformation of the rubber reduces vibration during subsequent operation. Then, insert the two elastic buckles 303 into the corresponding slots 302 to achieve initial engagement and fixation of the connecting block 2 and the maintenance arm 1, preventing the connecting block 2 from slipping axially. Finally, pass the bolt 307 through the pre-set through hole from the outer wall of the maintenance arm 1 and screw it into the threaded grooves 306 on the outer wall of the two guide blocks 304. The bolt 307 is tightened until it penetrates the maintenance arm 1 and extends to the bottom. Then, the nut 308 is tightened onto the protruding end of the bolt 307 to strengthen the fixation through threaded connection, preventing gaps between the connecting block 2 and the maintenance arm 1. Finally, the electromagnetic chuck 3091 and the iron fixing plate 3093 in the placement groove 3092 are activated to generate magnetic attraction, supplementing the axial fixation strength through magnetic force, ensuring that the connecting block 2 and the maintenance arm 1 do not have relative displacement during the maintenance process. The overall structure is simple and easy to replace. The corresponding workpiece carried by the connecting block 2 can be replaced according to different working conditions, improving maintenance efficiency.

[0027] Reference Figure 1 , Figure 3 and Figure 5 The clamping mechanism 6 includes a bidirectional lead screw 601, which controls the opposing movement of sliders 602. The outer wall of the bidirectional lead screw 601 is rotatably connected to the inner wall of the moving groove 5. Slider 602s are threadedly connected to both the front and rear ends of the outer wall of the bidirectional lead screw 601. The sliding of sliders 602s within the moving groove 5 causes the clamping bar 604 to rotate. Steering knuckles 603s are fixedly connected to the left sides of both sliders 602s, facilitating the rotation of the clamping bar 604. The left sides of the inner wall of the moving groove 5 are also connected to the sliders 602s. The actuator 4 is connected to a clamping bar 604, the right end of which is connected to the steering knuckle 603. Anti-slip pads 605 are fixedly connected to adjacent sides of the two clamping bars 604. The anti-slip pads 605 can prevent the clamping bars 604 from slipping when clamping the workpiece. Pressure sensors 606 are fixedly connected to adjacent sides of the two anti-slip pads 605. The pressure sensors 606 are used to detect the clamping pressure. A power assembly 607 is provided at the front end of the actuator 4. The power assembly 607 is used to provide power. The power assembly 607 includes a servo motor 6071, which serves as a power source. The rear of the servo motor 6071 is fixedly connected to the front end of the actuator 4. A fixed gear 6072 is fixedly connected to the output end of the servo motor 6071, and a moving gear 6073 is fixedly connected to the front end of the bidirectional lead screw 601. The fixed gear 6072 and the moving gear 6073 are used to transmit power. Specifically, when the device clamps the workpiece, the servo motor 6071 drives the fixed gear 6072 to rotate. The fixed gear 6072 meshes with the moving gear 6073, causing the bidirectional lead screw 601 to rotate synchronously on the inner wall of the moving groove 5. As the bidirectional lead screw 601 rotates, the two sliders 602 are driven by the threaded connection and slide towards each other along the moving groove 5. The sliders 602 drive the clamping bars 604 through the left steering knuckle 603, causing the two clamping bars 604 to rotate synchronously towards each other around the rotation point on the inner wall of the moving groove 5, gradually approaching the workpiece. During the clamping process... The anti-slip pad 605 first contacts the workpiece, preventing it from slipping due to surface friction. The pressure sensor 606 monitors the clamping pressure in real time to prevent excessive pressure from damaging the workpiece or insufficient pressure from causing it to fall off. When the pressure reaches the preset value, the servo motor 6071 stops running and locks the bidirectional lead screw 601, keeping the clamping bar 604 in a stable clamping state and completing the workpiece fixation. When the workpiece is released, the servo motor 6071 reverses, driving the slider 602 to slide in the opposite direction, and the clamping bar 604 opens accordingly, reducing operational errors and improving the stability and efficiency of tool clamping during street light maintenance.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The steering mechanism 7 includes a stepper motor 701, which provides power for the rotation of the actuator 4 around its axis. The right side of the stepper motor 701 is fixedly connected to the middle of the left end of the connecting block 2. Two steering bars 702 are fixedly connected to the right end of the actuator 4. An auxiliary groove 703 is provided on the left end of the connecting block 2, and the steering bars 702 slide within the auxiliary groove 703 to prevent unstable connection between the actuator 4 and the connecting block 2. The temperature compensation mechanism 8 includes multiple temperature detectors 801, which are used to detect the temperature of the maintenance arm 1. The rear ends of the multiple temperature detectors 801 are all fixedly connected to the outer wall of the maintenance arm 1. On the front side, multiple heating wires 802 are fixedly connected to the outer wall of the maintenance arm 1. The heating wires 802 heat up when the temperature is low. Two hidden grooves 9 are opened on the outer wall of the maintenance arm 1. The hidden grooves 9 are used to hide the bolts 307 and nuts 308. Two elastic protective plates 10 are fixedly connected to the left side of the inner wall of the moving groove 5. The elastic protective plates 10 can be penetrated by the clamping strip 604 to prevent impurities from falling into the moving groove 5. An infrared monitor 11 is fixedly connected to the middle of the left end of the actuator 4. The infrared monitor 11 is used to monitor the operating status of the device. An alarm 12 is fixedly connected to the top of the maintenance arm 1. The alarm 12 is used to issue an alarm. Specifically, when the actuator 4 needs to rotate to make the clamping structure more convenient for clamping the workpiece, the stepper motor 701 drives the actuator 4 to rotate around its own central axis. The steering bar 702 at the right end of the actuator 4 slides along the auxiliary groove 703 at the left end of the connecting block 2 to ensure stable connection without shaking during rotation, thus achieving precise adjustment of the rotation angle of the actuator 4. The temperature detector 801 monitors the temperature of the outer wall of the maintenance arm 1 in real time and automatically activates the heating wire 802 to generate heat when the temperature is low, maintaining the stable operating temperature of the robotic arm. The hidden groove 9 stores the bolts 307 and nuts 308 to prevent exposed parts from being corroded by the environment and enhances the smoothness of the device surface. The elastic protective plate 10 is penetrated by the clamping bar 604, which can block dust and impurities from entering the moving groove 5. The infrared monitor 11 monitors the operating status of the device in real time. When it detects that the parts are loose or the temperature exceeds the limit, the alarm 12 at the top of the maintenance arm 1 immediately sounds an alarm to remind the operator to deal with it in time and ensure maintenance safety.

[0029] Working principle: The precise fit between guide block 304 and guide groove 305 ensures the positioning accuracy of connecting block 2 and maintenance arm 1, avoiding installation deviations. Rubber pad 301 absorbs vibration through elastic deformation, reducing the impact of mechanical impact on the connection structure during operation. Then, the engagement of elastic buckle 303 and buckle groove 302 generates a tightening force, utilizing the elastic potential energy of the buckle to achieve initial fixation and prevent connecting block 2 from slipping. Finally, the threaded connection of bolt 307, threaded groove 306, and nut 308 forms a rigid mechanical lock, achieved through thread pre-tightening. The force eliminates the connection gap, enhances the strength of the fixed connection, and prevents relative shaking between the connecting block 2 and the maintenance arm 1. Finally, after the electromagnetic chuck 3091 is energized, it generates a magnetic attraction with the iron fixing plate 3093, which supplements the axial constraint force and further prevents the connecting block 2 from shifting. By using multiple fixing structures, the convenience of connection is ensured, and the stability of connection is improved through mechanical locking force and magnetic force, which meets the requirements of street light maintenance for connection reliability. At the same time, the connecting block 2 and the tools adapted on the connecting block 2 can be quickly replaced to adapt to different working scenarios. Furthermore, the servo motor 6071 drives the fixed gear 6072 to rotate, and the meshing connection between the gears transmits power to the moving gear 6073, driving the bidirectional lead screw 601 to rotate within the moving groove 5. The bidirectional lead screw 601 converts rotational motion into linear motion through a threaded connection, causing the sliders 602 at the front and rear ends of the outer wall to slide precisely towards each other along the moving groove 5. The sliders 602 drive the clamping bar 604 through the steering knuckle 603, and the rotational characteristics of the steering knuckle 603 cause the clamping bar 604 to rotate around the inner wall of the moving groove 5. The synchronous rotation of the points completes the clamping of the workpiece. During the clamping process, the anti-slip pad 605 prevents the workpiece from slipping through surface friction. The pressure sensor 606 monitors the clamping force in real time. When the pressure reaches the preset value, it controls the servo motor 6071 to stop and locks the bidirectional lead screw 601 to ensure stable clamping force. When the workpiece is released, the servo motor 6071 rotates in the opposite direction, thereby driving the slider 602 to slide in the opposite direction, so that the clamping bar 604 can flexibly release the workpiece, avoid damage, and improve the stability of tool clamping during street light maintenance.
