Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] To address the issue of existing robotic spraying arms having difficulty adjusting the spraying angle at the end effector, thus affecting the actual spraying quality, please refer to [link to relevant documentation]. Figure 1 - Figure 4 This embodiment provides the following technical solution:

[0021] The end leveling device of the air compressor parts spraying robot arm includes a robot arm end 1, a connecting frame 2 is set below the robot arm end 1, the inside of the connecting frame 2 is rotatably connected to the spraying equipment housing 3 via a rotating shaft, a movable frame 302 is installed below the spraying equipment housing 3, a lifting block 305 is set on one side of the movable frame 302, and a threaded screw 203 passes through the inside of the lifting block 305. The threaded screw 203 is adjusted by a motor 202 and a speed regulator 204 installed inside the fixed seat 201 on one side of the connecting frame 2.

[0022] The fixed base 201 houses a motor 202, and a speed regulator 204 is installed at the lower end of the motor 202. The motor shaft of the motor 202 is connected to the threaded screw 203 through the speed regulator 204. The motor 202 drives the speed regulator 204 to adjust the threaded screw 203.

[0023] The movable frame 302 is fixedly connected to the outer shell 3 of the spraying equipment. An adjusting arm 304 is installed at the lower end of the movable frame 302, and a connecting rod 303 is installed in the middle of the movable frame 302. The upper end of the adjusting arm 304 is rotatably connected to the movable frame 302 through the connecting rod 303, and the lower end of the adjusting arm 304 is rotatably connected to the lifting block 305 through the rotating shaft. The outer shell 3 of the spraying equipment is limited by the rotating shaft to perform rotational leveling work, adapting to the optimal spraying angle to improve work quality. The structure is simple, the positional stability is good, and it is easy to operate.

[0024] The movable frame 302 has an integrally formed movable opening 308 on one side inside. The adjusting arm 304 passes through the movable opening 308 and is slidably connected to the movable frame 302. The threaded screw 203 passes through the lifting block 305 and is threadedly connected to the lifting block 305. When the threaded screw 203 rotates, it can drive the lifting block 305 to move up and down. After the lifting block 305 moves, one end drives the lower end of the adjusting arm 304 to move, thereby moving the movable frame 302 and the outer shell 3 of the spraying equipment.

[0025] Specifically, a motor 202 and a speed controller 204 are installed inside the fixed base 201 on one side of the connecting frame 2 to adjust the threaded screw 203. The rotation of the threaded screw 203 can drive the lifting block 305 to rise and fall. After the lifting block 305 moves, one end drives the lower end of the adjusting arm 304 to move, which in turn drives the movable frame 302 and the spraying equipment housing 3 to move. The spraying equipment housing 3 is limited by the rotating shaft and performs rotational leveling work to adapt to the optimal spraying angle, thereby improving the work quality. The structure is simple, the positional stability is good, and it is easy to operate.

[0026] To address the issues of inadequate nozzle position adjustment, complex and cumbersome structure, and other problems associated with the practical use of existing robotic spraying arms, please refer to [link to relevant documentation]. Figure 1 - Figure 4 This embodiment provides the following technical solution:

[0027] Fixed seats 201 are installed on both sides of the outer side of the connecting frame 2. The rotating shafts on both sides of the spraying equipment housing 3 are rotatably connected to the spraying equipment housing 3 and the fixed seats 201 respectively through bearings. The fixed seats 201 keep the position stable and limit the two ends of the spraying equipment housing 3.

[0028] A mounting plate 101 is installed at the lower end of the robotic arm end 1. A servo motor is installed at the upper end of the mounting plate 101, and the servo motor extends into the robotic arm end 1 and is fixedly connected to the robotic arm end 1. A rotating shaft 102 is installed at the lower end of the mounting plate 101. The rotating shaft 102 is fixedly connected to the connecting frame 2 through a coupling. The motor shaft of the servo motor is fixedly connected to the rotating shaft 102. The spraying structure is installed below the robotic arm end 1 through the connecting frame 2. The servo motor installed at the bottom of the robotic arm end 1 can drive the connecting frame 2 and the spraying equipment housing 3 to move and adjust the rotation angle of the spraying equipment housing 3 so as to perform spraying work on the air compressor parts.

[0029] The front end of the spraying equipment housing 3 is equipped with an atomizing nozzle 301, and the rear end of the spraying equipment housing 3 is equipped with a booster pump 306. The booster pump 306 is sealed to the atomizing nozzle 301. The rear end of the spraying equipment housing 3 is equipped with a paint inlet pipe 307, which is connected to the booster pump 306. Paint is introduced through the paint inlet pipe 307, and air is introduced through the booster pump 306. The paint inlet pipe 307 works with the atomizing nozzle 301 to perform atomization and spray the air compressor parts. The structure is compact, easy to operate, and has good adaptability.

[0030] Specifically, paint is introduced through the paint inlet pipe 307, and air is introduced through the booster pump 306. The atomizing nozzle 301 is used for atomization. The structure is compact, easy to operate, and has good adaptability. The spraying structure is installed below the end of the robotic arm 1 through the connecting frame 2. A servo motor is installed at the bottom of the end of the robotic arm 1, which can drive the connecting frame 2 and the spraying equipment housing 3 to move and adjust the rotation angle of the spraying equipment housing 3. The fixed seat 201 keeps the position stable and limits the two ends of the spraying equipment housing 3.

[0031] Working Principle: During use, the robotic arm is adjusted to change the position of its end 1. The spraying structure is mounted below the end 1 via a connecting frame 2. A servo motor mounted at the bottom of the end 1 drives the connecting frame 2 and the spraying equipment housing 3 to move, adjusting the rotation angle of the housing. The fixed base 201 maintains a stable position and limits the movement of both ends of the housing. Paint is introduced through the paint inlet pipe 307, and air is introduced through the booster pump 306. This air, combined with the atomizing nozzle 301, atomizes the air compressor components, resulting in a sprayed coating. The structure is compact, easy to operate, and highly adaptable. A motor 202 and a speed controller 204 are installed inside the fixed base 201 on one side of the connecting frame 2 to adjust the threaded screw 203. The rotation of the threaded screw 203 drives the lifting block 305 to rise and fall. After the lifting block 305 moves, one end drives the lower end of the adjusting arm 304 to move, which in turn drives the movable frame 302 and the spraying equipment housing 3 to move. The spraying equipment housing 3 is limited by the rotating shaft to perform rotational leveling work, adapting to the optimal spraying angle to improve work quality. The structure is simple, has good positional stability, and is easy to operate.
