Description

Technical Field

[0001] This utility model relates to the field of spraying robots, specifically to a mobile spray gun structure for a building spraying robot. Background Technology

[0002] With socio-economic development and population growth, modern cities are seeing an increasing number of high-rise buildings. The appearance of building surfaces has become a key focus of public attention regarding the urban landscape. In recent years, the accelerated urbanization process and the development of the construction industry have led to a surge in demand for exterior wall coatings, making them an indispensable building material in areas such as urban infrastructure construction, real estate development, and renovation of old buildings. While existing building spraying robots can perform automated spraying, their stability and uniformity can only be controlled through horizontal and vertical displacement, resulting in poor uniformity and a long spraying time. Therefore, it is necessary to design a mobile spray gun structure for building spraying robots that can improve spray uniformity and reduce spraying time. Utility Model Content

[0003] The purpose of this utility model is to provide a mobile spray gun structure for a building spraying robot.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A mobile spray gun structure for a building spraying robot is provided, including a horizontal moving mechanism, a horizontal rotating mechanism, a vertical rotating mechanism, a spray gun, and a spray gun start / stop mechanism. The horizontal moving mechanism is fixedly installed on a suspended platform and is used to drive the spray gun to move horizontally. The horizontal rotating mechanism is fixedly installed on a displacement seat of the horizontal moving mechanism and is used to drive the spray gun to rotate horizontally to change its angle. The vertical rotating mechanism is fixedly installed on a rotating seat of the horizontal rotating mechanism and is used to drive the spray gun to rotate vertically to change its angle. The spray gun is fixedly installed on a rotating disc of the vertical rotating mechanism and is used to spray paint onto the exterior walls of buildings. The spray gun start / stop mechanism is fixedly installed on the vertical rotating mechanism and is used to push the start handle to spray paint along the spray gun.

[0006] Furthermore, the horizontal movement mechanism also includes a toothed belt, a pulley, a drive motor, two guide wheels, and two guide rails fixedly mounted on the suspended platform. The bottom of the displacement seat is fixedly provided with a guide seat that is slidably connected to the guide rail. The pulley is located between the two guide rails, and both ends of the pulley are fixedly connected to the suspended platform. The two guide wheels are located on both sides of the bottom of the pulley. The pulley is fixedly mounted on the output end of the drive motor. The drive motor is fixedly mounted on the displacement seat through a motor mount. The toothed surface of the pulley meshes with the pulley, and the smooth surface of the pulley contacts the two guide wheels.

[0007] Furthermore, the horizontal rotation mechanism also includes a harmonic reducer and a drive motor for driving the harmonic reducer to rotate. The output end of the harmonic reducer is fixedly connected to the displacement seat, and the rotation seat is fixedly connected to the housing of the harmonic reducer.

[0008] Furthermore, the vertical rotation mechanism also includes a second drive motor fixedly mounted on the rotating base, and the rotating disk is fixedly connected to the output end of the second drive motor.

[0009] Furthermore, a clamping block is fixedly installed on the side of the rotating disc, and the spray gun is fixedly connected to the clamping block. A clamping ring for fixing the spray gun barrel is also fixedly installed on the vertical rotating mechanism.

[0010] Furthermore, the spray gun start-stop mechanism includes a third drive motor, a gear, a rack, and a second guide seat. The third drive motor and the second guide seat are fixedly mounted on the rotating disk via a support frame. The rack is horizontally slidably connected to the second guide seat via a second guide rail. The gear is fixedly mounted on the output end of the third drive motor, and the gear meshes with the rack.

[0011] Furthermore, a pusher block is fixedly provided at the end of the rack.

[0012] The beneficial effects of this invention are as follows: This building spraying robot uses a mobile spray gun structure, which drives the spray gun to move horizontally via a toothed belt, achieving high precision in displacement.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0022] Reference Figures 1 to 5 The illustrated mobile spray gun structure for a building spraying robot includes a horizontal moving mechanism 1, a horizontal rotating mechanism 2, a vertical rotating mechanism 3, a spray gun 4, and a spray gun start / stop mechanism 5. The horizontal moving mechanism 1 is fixedly installed on a suspended platform 6 and is used to drive the spray gun 4 to move horizontally. The horizontal rotating mechanism 2 is fixedly installed on a displacement seat 1a of the horizontal moving mechanism 1 and is used to drive the spray gun 4 to rotate horizontally to change its angle. The vertical rotating mechanism 3 is fixedly installed on a rotating seat 2a of the horizontal rotating mechanism 2 and is used to drive the spray gun 4 to rotate vertically to change its angle. The spray gun 4 is fixedly installed on a rotating disc 3a of the vertical rotating mechanism 3 and is used to spray paint onto the exterior walls of buildings. The spray gun start / stop mechanism 5 is fixedly installed on the vertical rotating mechanism 3 and is used to push the start handle 4a to spray paint along the spray gun 4. When the suspended platform 6 is suspended above the building's exterior wall by steel cables, the spray gun start / stop mechanism 5 rotates the start handle 4a, causing paint to be sprayed from the spray gun 4. The suspended platform 6 drives the spray gun start / stop mechanism 5 to move horizontally, and combined with the vertical movement of the platform 6, ensures that the entire exterior wall of the building can be sprayed. After each descent a certain distance, the vertical rotation mechanism 3 operates simultaneously as the displacement seat 1a moves horizontally, increasing the spraying area of ​​the spray gun 4 and improving the uniformity of the spray. Furthermore, when spraying the corners of the building, the horizontal rotation mechanism 2 drives the spray gun 4 to rotate horizontally, ensuring that the corners are sprayed more evenly and avoiding noticeable seams.

[0023] The horizontal moving mechanism 1 also includes a toothed belt 1c, a pulley 1d, a drive motor 1e, two guide wheels 1f, and two guide rails 1b fixedly mounted on the suspended platform 6. A guide seat 1 is fixedly mounted at the bottom of the displacement seat 1a and slidably connected to the guide rails 1b. The pulley 1d is located between the two guide rails 1b, with both ends of the pulley 1d fixedly connected to the suspended platform 6. The two guide wheels 1f are located on both sides of the bottom of the pulley 1d. The pulley 1d is fixedly mounted on the output end of the drive motor 1e, which is fixedly mounted on the displacement seat 1a via a motor mount. The toothed surface of the pulley 1d meshes with the pulley 1d, and the smooth surface of the pulley 1d contacts the two guide wheels 1f. By controlling the drive motor 1e to operate, the pulley 1d can be driven to rotate. The pulley 1d, through meshing with the toothed belt 1c, can drive the displacement seat 1a to slide horizontally along the guide rails 1b. The guide wheels 1f press the toothed belt 1c tightly onto the pulley 1d.

[0024] The horizontal rotation mechanism 2 also includes a harmonic reducer 2b and a drive motor for driving the rotation of the harmonic reducer 2b. The output end of the harmonic reducer 2b is fixedly connected to the displacement seat 1a, and the rotating seat 2a is fixedly connected to the housing of the harmonic reducer 2b. This inverted structure shortens the distance between the rotating seat 2a and the displacement seat 1a, making it more stable. When the drive motor operates, it drives the output end of the harmonic reducer 2b to rotate, and the harmonic reducer 2b, through the rotation of its housing, drives the rotating seat 2a to rotate and change position.

[0025] The vertical rotation mechanism 3 also includes a second drive motor 3b fixedly mounted on the rotating base 2a, and the rotating disk 3a is fixedly connected to the output end of the second drive motor 3b. By controlling the second drive motor 3b to work, the second drive motor 3b can drive the rotating disk 3a to rotate.

[0026] A clamping block 3c is fixedly installed on the side of the rotating disk 3a. The spray gun 4 is fixedly connected to the clamping block 3c. A clamping ring for fixing the barrel of the spray gun 4 is also fixedly installed on the vertical rotating mechanism 3. The clamping ring is used to prevent the spray gun 4 from rotating on the clamping block 3c. Through the action of the clamping block 3c, the spray gun 4 can be fixedly installed on the rotating disk 3a.

[0027] The spray gun start / stop mechanism 5 includes a drive motor 5a, a gear 5b, a rack 5c, and a guide seat 5e. The drive motor 5a and guide seat 5e are fixedly mounted on the rotating disk 3a via a support frame. The rack 5c is horizontally slidably connected to the guide seat 5e via a guide rail 5d. The gear 5b is fixedly mounted on the output end of the drive motor 5a and meshes with the rack 5c. By controlling the drive motor 5a to operate, the drive motor 5a drives the gear 5b to rotate, which in turn causes the gear 5b to push the rack 5c to slide horizontally, thereby actuating the start handle 4a and opening the spray gun 4.

[0028] A pusher block 5f is fixedly installed at the end of the rack 5c. The pusher block 5f increases the contact area between the rack and the start handle 4a, ensuring that the spray gun 4 can be opened.

[0029] This building spraying robot uses a mobile spray gun structure, which drives the spray gun to move horizontally via a toothed belt, achieving high precision in displacement. Furthermore, through horizontal and vertical rotation mechanisms, the spray gun can rotate and oscillate up and down and left and right during the spraying process, resulting in a larger sprayed area, reduced spraying time, and improved uniformity.

[0030] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
