[0002] An exterior wall painting robot is a type of equipment used in the field of building automation for spraying exterior walls. It is tightly connected to the exterior wall through special attachment devices, which can be vacuum suction, mechanical clamps, or a combination of both, allowing it to stably climb or attach to the building's facade. The frame is typically made of high-strength metal, ensuring overall robustness while reducing its own weight for better adaptation to exterior wall operations. The frame is equipped with precision drive motors and transmission devices, enabling the robot to move up, down, left, and right along a preset route on the exterior wall surface to achieve the spraying process.

[0003] The existing technology, disclosed in CN216406052U, discloses a building exterior wall spraying robot, which includes a rooftop hoisting mechanism and a spraying robot body. The spraying robot body is suspended from the rooftop hoisting mechanism by a flexible rope and can move up and down along the flexible rope. The spraying robot body includes a robot housing, on which sliding wheels and a spraying module are installed. The spraying module includes a nozzle and a telescopic rod. The telescopic rod is fixed to the robot housing, and the nozzle is fixed to the telescopic rod. The above-mentioned patent cannot achieve multi-angle adjustment of the spraying nozzle, resulting in insufficient spraying range. Because the nozzle cannot change the spraying angle in a timely manner according to the actual situation, the paint cannot be evenly and completely adhered to the wall surface. This not only reduces construction efficiency but also causes the coating to be too thin or too thick in some areas, affecting the overall aesthetics and protective performance of the exterior wall. It cannot fully meet the diverse spraying needs of modern buildings and brings many inconveniences and challenges to exterior wall spraying operations. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0010] Both drive components include motors, with the front sides of the motors respectively mounted on the rear side of the fixed frame.

Rotating blocks are connected to the front sides of both drive shafts.

[0011] The application mechanism includes a collection frame, the rear side of which is connected to the front side of the outer frame.

[0012] As a preferred embodiment of the multi-angle spray head rotation structure of the exterior wall spraying robot of this utility model, each of the drive components is connected to a conical shaft on its front side, each of the conical shafts is connected to a mounting plate on its front side, each of the mounting plates is hinged to a universal ball on its front side, each of the universal balls is connected to a fixed plate on its front side, and each of the two fixed plates is connected to a connecting rod inside.

[0013] As a preferred embodiment of the multi-angle spray head rotation structure of the exterior wall spraying robot of this utility model, the rear side of the connecting rod is connected to the front side of the fixed frame, two rotating spray heads are connected to the front side of each of the two mounting plates, and two movable balls are connected to the rear side of each mounting plate.

[0014] As a preferred embodiment of the multi-angle spray head rotation structure of the exterior wall spraying robot of this utility model, a fixing block is hinged to the rear side of the fixing frame, and a guide component is provided on the outside of the fixing block. The guide component includes a guide rod, and the side of the guide rod near the cone axis is respectively connected to the outside of the fixing block. Two guide grooves are opened on the outside of the fixing frame, and the outside of the guide rod is slidably connected to the inside of the guide groove. A sliding rod is connected to the rear side of the fixing block, and the outside of the sliding rod is slidably connected to the inside of the fixing frame.

[0015] As a preferred embodiment of the multi-angle spray head rotation structure of the exterior wall spraying robot of this utility model, each sliding rod is fitted with a spring, one end of the spring is connected to the rear side of the fixing block, and the other end of the spring is connected to the inside of the fixing frame. Each sliding rod is connected to a limit plate.

[0016] As a preferred embodiment of the multi-angle spray head rotation structure of the exterior wall spraying robot of this utility model, the inside of the collection frame is connected to a sleeve, the inside of the collection frame is slidably connected to a sliding shaft, the outside of the sliding shaft is slidably connected to the inside of the outer frame, the outside of the sliding shaft is connected to a fixing ring, the outside of the fixing ring is slidably connected to the inside of the sleeve, and a spring is sleeved on the outside of the sliding shaft.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the multi-angle spray head rotation structure of the exterior wall spraying robot has a reasonable structural design;

[0019] 1. The motor drives the drive shaft to rotate, which in turn causes the rotating block, cone shaft, and mounting plate to work together, allowing the mounting plate to swing around the universal ball, thereby driving the rotating spray head to swing at multiple angles. Simultaneously, as the mounting plate swings, components such as the fixing block, guide rod, and springs cooperate to ensure the accuracy and stability of the mounting plate's movement. This allows the rotating spray head to continuously change its spraying angle during its movement, achieving omnidirectional and multi-angle spraying operations. This significantly increases the coverage area of ​​a single operation, effectively reduces the number of robot movements and operation time, and improves the efficiency of exterior wall spraying.

[0020] 2. When the robot is placed parallel to the exterior wall, the roller contacts the wall surface, the connecting frame moves backward, and the sliding shaft drives the fixing ring to compress and rebound the spring, keeping the roller in close contact with the wall. This ensures that after the paint is sprayed onto the exterior wall, the roller can spread the paint evenly, avoiding paint accumulation or uneven application, thus improving the quality and aesthetics of the coating. Simultaneously, the design of the collection frame and triangular blocks can collect dripping paint. The tilt angle of the triangular blocks guides the paint into the collection frame, preventing paint from dripping onto the exterior wall or ground, reducing environmental pollution and material waste, maintaining a clean construction environment, facilitating subsequent cleanup, and lowering construction costs and environmental impact.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] In this technical solution, the multi-angle rotating nozzle structure of the exterior wall spraying robot includes an outer frame 1, which serves as the main frame of the robot, supporting and fixing other components. A feeding mechanism is located on the rear inner side of the outer frame 1, including a storage bin 2, which is a container for storing spray paint. The storage bin 2 is externally and fixedly connected to the inside of the outer frame 1. Sprayers 3 are installed on both the left and right sides of the storage bin 2. The sprayers 3 are connected to the rotating nozzle 14 via a conveying pipe to transport the spray paint. The sprayers 3 are responsible for conveying the spray paint from the storage bin 2 to the rotating nozzle 14 at a certain pressure and flow rate, and then spraying it onto the exterior wall. Multiple connecting posts 4 are fixedly connected inside the outer frame 1. Two of the connecting posts 4 have angle adjustment mechanisms at their bottoms, serving to connect the outer frame 1 to these mechanisms. The tops of the other two connecting posts 4 are fixedly connected to the bottoms of the two angle adjustment mechanisms. A uniform coating mechanism is located on the front side of the outer frame 1. Two traction wheels 32 are fixedly connected to the top of the outer frame 1 and, through connection to the traction rope of the traction machine, enable the robot to move on the outer wall. Multiple walking wheels are located on the front side of the outer frame 1.

[0029] Reference Figures 1 to 3The angle adjustment mechanism includes two fixed frames 5, the tops of which are fixedly connected to the bottoms of two connecting columns 4. Each fixed frame 5 has a drive assembly for providing power at its rear. Each drive assembly includes a motor 6, which serves as the power source for the angle adjustment mechanism. The front of each motor 6 is mounted on the rear of the two fixed frames 5. The output ends of each motor 6 are fixedly connected to drive shafts 7, which are rotatably connected to the inside of the fixed frames 5. Rotating blocks 8 are fixedly connected to the front of each drive shaft 7, allowing the drive shafts 7 to rotate smoothly and transmit the rotational motion of the motors 6 to the rotating blocks 8. Conical shafts 9 are fixedly connected to the front of each drive assembly, and mounting plates 10 are fixedly connected to the front of each conical shaft 9. Universal balls 11 are hinged to the front of each mounting plate 10. When the rotating blocks 8 rotate, the conical shafts 9 rotate accordingly. Due to their special inclined fixing method, the mounting plates 10 can swing around the universal balls 11, thereby enabling multi-angle swinging of the rotating nozzle 14 and expanding the spraying range. Each of the two omnidirectional balls 11 has a fixed plate 12 fixedly connected to its front side. A connecting rod 13 is fixedly connected inside each of the two fixed plates 12. The connecting rod 13 strengthens the connection between the fixed plate 12 and the fixed frame 5, improving the overall rigidity and stability of the angle adjustment mechanism. The rear side of the connecting rod 13 is fixedly connected to the front side of the fixed frame 5. Each of the two mounting plates 10 has two fixedly connected rotating nozzles 14. The rotating nozzles 14 can evenly disperse and spray the paint from the sprayer 3 onto the exterior wall, forming a high-quality coating. The swinging and rotating action of the mounting plates 10 enables multi-angle, all-around spraying, greatly improving the spraying range and efficiency, ensuring uniform and complete coverage of the exterior wall surface.

[0030] Reference Figures 2 to 4Two movable balls 15 are fixedly connected to the rear sides of each of the two mounting plates 10. The movable balls 15 play an auxiliary support and guiding role during the movement of the mounting plates 10, ensuring the smoothness and flexibility of the movement of the mounting plates 10. Multiple fixing frames 5 are hinged to the rear sides of multiple fixing blocks 16. Multiple fixing blocks 16 are provided with guide components on their exteriors. Each guide component includes a guide rod 17. The guide rods 17 are fixedly connected to the exterior of the multiple fixing blocks 16 on the side near the conical shaft 9. Two guide grooves 18 are formed on the exterior of each of the two fixing frames 5. The exterior of the guide rods 17 is slidably connected to the interior of the guide grooves 18. During the movement of the mounting plates 10, the guide rods 17 slide along the guide grooves 18, providing precise guidance, limiting the movement direction of the mounting plates 10, and ensuring its accuracy and stability during angle adjustment. Each of the multiple fixed blocks 16 has a sliding rod 19 fixedly connected to its rear side. The sliding rod 19 is externally slidably connected to the inside of the fixed frame 5. During the movement of the mounting plate 10, the sliding rod 19 can slide freely within the fixed frame 5, providing auxiliary support and guidance, while ensuring the relative position stability between the fixed blocks 16 and the fixed frame 5. Each of the multiple sliding rods 19 is fitted with a spring 20. One end of the spring 20 is fixedly connected to the rear side of the fixed block 16, and the other end is fixedly connected to the inside of the fixed frame 5. When the mounting plate 10 rotates or shifts, the spring 20 will compress or rebound accordingly, using its elasticity to adapt to the movement changes of the mounting plate 10, ensuring that the connection between the fixed blocks 16 and the mounting plate 10 is always in a proper tension state. Each of the multiple sliding rods 19 has a limiting plate 21 fixedly connected to its rear side. The limiting plate 21 restricts the sliding stroke of the sliding rod 19 within the fixed frame 5, preventing excessive displacement of the sliding rod 19 that could lead to collisions or damage between components, and ensuring the safe operation of the angle adjustment mechanism.

[0031] Reference Figures 2 to 4The uniform coating mechanism includes a collection frame 22, whose rear side is fixedly connected to the front side of the outer frame 1. The collection frame 22 is used to collect the spray paint dripping during the spraying process, preventing the spray paint from dripping onto the exterior wall or ground, causing environmental pollution and material waste. A sleeve 23 is fixedly connected inside the collection frame 22, and a sliding shaft 24 is slidably connected inside the collection frame 22. The outside of the sliding shaft 24 is slidably connected to the inside of the outer frame 1, and a fixing ring 25 is fixedly connected to the outside of the sliding shaft 24. The outside of the fixing ring 25 is slidably connected to the inside of the sleeve 23. A spring 26 is sleeved on the outside of the sliding shaft 24. When the roller 30 contacts the wall and causes the connecting frame 28 to move rearward, the spring 26 is compressed, generating elastic force. This elastic force pushes the connecting frame 28 and the roller 30 forward, ensuring that the roller 30 remains in close contact with the wall, thereby ensuring that the spray paint is evenly spread after being sprayed onto the exterior wall. A limiting disk 27 is fixedly connected to the rear side of the sliding shaft 24, which limits the displacement stroke of the sliding shaft 24. A connecting frame 28 is fixedly connected to the front side of the sliding shaft 24, which supports the rotation of the roller 30. A fixed shaft 29 is fixedly connected inside the connecting frame 28, and the roller 30 is rotatably connected to the outside of the fixed shaft 29. The roller 30 is used to evenly spread the paint sprayed onto the exterior wall. A triangular block 31 is fixedly connected to the top of the connecting frame 28. The triangular block 31 has a certain tilt angle, which allows dripping paint to slide down its surface into the collection frame 22, reducing paint residue on the robot's surface and the possibility of dripping onto the ground.

[0032] Working Principle: When using this exterior wall spraying robot, first connect the traction rope of the traction machine to the outside of the traction wheel 32, enabling the robot to walk on the exterior wall. Then, place the robot parallel to the exterior wall, causing the roller 30 to contact the wall surface. This causes the connecting frame 28 to move backward, displacing the sliding shaft 24 and the fixed ring 25. This causes the spring 26 to compress and rebound, bringing the roller 30 into close contact with the wall until the walking wheel contacts the wall. This ensures that the paint is evenly applied after being sprayed onto the exterior wall. Simultaneously, the triangular block 31 and the collection frame 22 collect any dripping paint, preventing it from falling onto the exterior wall or ground. Then, start the traction machine to enable the robot to walk. During walking, start the motor 6 to drive the robot. When shaft 7 and rotating block 8 rotate, the conical shaft 9 rotates, which in turn drives the mounting plate 10 to rotate. Since the rear side of the conical shaft 9 is tilted and fixed inside the rotating block 8, the mounting plate 10 can swing around the universal ball 11. This causes the rotating nozzle 14 to swing, thereby expanding the spraying range of the rotating nozzle 14. As the mounting plate 10 swings, the fixing block 16 will shift, allowing the guide rod 17 to slide inside the guide groove 18. This causes the spring 20 to compress or rebound, and the elastic force of the spring 20 can adapt to the rotation and displacement of the mounting plate 10. At this time, the sprayer 3 can be started to transport the paint in the storage bin 2 through the conveying pipe to the inside of the rotating nozzle 14 for spraying. Thus, the rotatable characteristic of the rotating nozzle 14 can further increase the spraying range.
