Description

Technical Field

[0001] This invention relates to intelligent construction devices, specifically to an intelligent construction device for indoor wall spraying. Background Technology

[0002] When decorating a building, it is often necessary to paint the interior walls. Most existing painting methods involve workers holding a spray gun and spraying the paint onto the wall. However, workers need to hold the spray gun for a long time during the painting process, which is very physically demanding. At the same time, workers move the spray gun based on their personal experience, and it is difficult to keep the movement speed consistent, which can easily lead to uneven paint thickness. This is not only time-consuming and labor-intensive, but also inefficient and makes it difficult to maintain a good painting effect.

[0003] With the advancement of science and technology and the development of the times, automated and intelligent spraying devices will gradually replace traditional manual spraying and become an important means of modern industrial intelligence, promoting the construction and decoration industry towards a greener and more efficient direction. For example, an automatic spraying machine is disclosed in the invention patent application with publication number CN118855194A.

[0004] The above-mentioned automatic spraying machine has the following problems: The aforementioned automatic spraying machine can only spray paint vertical walls and cannot spray paint ceilings. Its functions are insufficient and its use is limited, so it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide an intelligent construction device for indoor wall spraying. This intelligent construction device can not only spray and process vertical walls, but also spray and process ceilings. It has multiple functions and can cope with more usage scenarios.

[0006] The objective of this invention is achieved through the following technical solution: An intelligent construction device for indoor wall spraying includes a spraying trolley, a spraying unit, and a position control mechanism; The painting trolley includes a painting frame, painting wheels, and a vehicle-mounted lifting mechanism, which is used to drive the position control mechanism to lift and lower. The spraying unit is mounted on the spraying frame of the spraying trolley. The spraying unit includes a nozzle, a paint delivery pipe, and a paint tank. The paint delivery pipe is used to deliver paint from the paint tank to the nozzle. The paint tank is located inside the spraying frame. The position control mechanism is mounted on the vehicle-mounted lifting mechanism. This mechanism includes a multi-axis robotic arm, a vertical-vertical integrated power mechanism, and a horizontal movement mechanism. The nozzle is mounted on the multi-axis robotic arm. The horizontal movement mechanism drives the multi-axis robotic arm to move laterally, and its driving direction is parallel to the vertical wall. The vertical-vertical integrated power mechanism drives the multi-axis robotic arm to move vertically and longitudinally. This mechanism includes a vertical-vertical integrated frame, a vertical-vertical integrated movement module, and a vertical-vertical integrated guide structure. The guide structure includes a vertical-vertical integrated guide rod, which comprises a vertical section, a curved section, and a longitudinal section. The vertical section is connected to the bottom of the curved section, and the longitudinal section is connected to the top of the curved section. The vertical-vertical integrated movement module moves on the guide rod, enabling the multi-axis robotic arm to move vertically and longitudinally.

[0007] In a preferred embodiment of the present invention, the vehicle-mounted lifting mechanism is composed of a scissor lift mechanism. The bottom of the scissor lift mechanism is fixedly installed inside the painting vehicle frame, and the top of the scissor lift mechanism is provided with a lifting base plate. The position control mechanism is disposed on the lifting base plate. The top of the painting vehicle frame is provided with a lifting clearance hole for avoiding the lifting movement of the scissor lift mechanism. This structure enables smooth and relatively large-stroke lifting movements, facilitating the overall lifting of the position control mechanism to a suitable height, making it particularly suitable for painting operations on high-rise walls or ceilings. Simultaneously, its compact structure minimizes space requirements during storage, facilitating indoor movement and arrangement. The lifting base plate and the painting vehicle frame cooperate through the lifting clearance hole, ensuring smooth and interference-free lifting, thus improving the overall structural rationality and operational reliability of the device.

[0008] In a preferred embodiment of the present invention, the vertical and longitudinal integrated power mechanism is disposed on the horizontal moving power mechanism.

[0009] In a preferred embodiment of the present invention, the vertical and vertical integrated moving module includes a vertical and vertical integrated moving base, vertical and vertical integrated moving rollers, a vertical and vertical integrated power motor, and a vertical and vertical integrated transmission structure. The vertical and vertical integrated moving rollers are rotatably connected to the vertical and vertical integrated moving base. The vertical and vertical integrated moving rollers are provided in multiple sets, and each set includes two vertical and vertical integrated moving rollers arranged opposite each other. The vertical and vertical integrated guide rod is clamped between the two vertical and vertical integrated moving rollers in the same set. The vertical and vertical integrated power motor is fixedly mounted on the vertical and vertical integrated frame.

[0010] The vertical and vertical integrated transmission structure includes a vertical and vertical integrated belt and vertical and vertical integrated pulleys, with multiple vertical and vertical integrated pulleys. The vertical and vertical integrated moving seat is fixedly connected to the vertical and vertical integrated belt. Through the above structure, by using multiple sets of relatively arranged moving rollers to clamp the guide rod, the stability and guiding accuracy of the moving module during transitions in the vertical, curved, and longitudinal sections are ensured, effectively preventing swaying and deviation during climbing or turning.

[0011] Furthermore, the vertically integrated moving rollers are provided in four sets, with the axial directions of two sets of vertically integrated moving rollers perpendicular to the axial directions of the other two sets. This enhances adaptability and stability in curved sections, ensuring a continuous and smooth movement trajectory of the spray head when switching between walls and ceilings, and guaranteeing the uniformity and consistency of the spraying process.

[0012] Furthermore, the vertical and longitudinal integrated guide rods are provided in two parallel horizontally, with two sets of vertical and longitudinal integrated moving rollers clamped on one of the vertical and longitudinal integrated guide rods, and the other two sets of vertical and longitudinal integrated moving rollers clamped on the other vertical and longitudinal integrated guide rod.

[0013] In a preferred embodiment of the present invention, the lateral movement mechanism includes a lateral movement drive motor and a lateral transmission assembly; the lateral transmission assembly includes a lateral lead screw and a lateral lead screw nut, the lateral lead screw nut being fixedly connected to the vertical and longitudinal integrated frame.

[0014] Compared with the prior art, the present invention has the following advantages: 1. By replacing manual hand-held spraying with a spraying trolley, multi-axis robotic arm and automated drive mechanism, the manual spraying is avoided and the physical exertion is significantly reduced.

[0015] 2. The integrated vertical and vertical guide rod design (including vertical, curved, and longitudinal sections) allows the spray head to smoothly switch its movement trajectory between vertical walls and ceilings, expanding the applicable scenarios of the device and meeting the spraying needs of different building structures.

[0016] 3. The vehicle-mounted lifting mechanism is a fully adjustable lifting control mechanism, which makes it easy to adjust the working height according to the height of the wall or the position of the ceiling, adapting to different indoor space sizes and enhancing practicality and adaptability.

[0019] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0020] Combination Figures 1-2 This embodiment of the intelligent construction device for indoor wall spraying includes a spraying trolley, a spraying unit, and a position control mechanism. The spraying trolley includes a spraying frame 1, spraying wheels 2, and a vehicle-mounted lifting mechanism 3. The vehicle-mounted lifting mechanism 3 is used to drive the position control mechanism to lift and lower. The vehicle-mounted lifting mechanism 3 is composed of a scissor lift mechanism. The bottom of the scissor lift mechanism is fixedly installed inside the spraying frame 1, and the top of the scissor lift mechanism is provided with a lifting base plate 4. The position control mechanism is mounted on the lifting base plate 4. The top of the spraying frame 1 is provided with a lifting clearance hole to allow the scissor lift mechanism to move freely. This structure enables smooth and relatively large-stroke lifting movements, facilitating the overall lifting of the position control mechanism to a suitable height, making it particularly suitable for spraying high-rise walls or ceilings. Simultaneously, its compact structure minimizes space requirements during storage, making it easy to move and arrange indoors. The lifting base plate 4 and the spraying frame 1 cooperate through the lifting clearance hole to ensure smooth and interference-free lifting, improving the overall structural rationality and operational reliability of the device.

[0021] Combination Figures 1-2 The spraying unit is mounted on the spraying frame 1 of the spraying trolley. The spraying unit includes a nozzle 5, a paint delivery pipe (not shown in the figure), and a paint tank 6. The paint delivery pipe is used to deliver the paint from the paint tank 6 to the nozzle 5. The paint tank 6 is located inside the spraying frame 1.

[0022] Combination Figures 1-2 The position control mechanism is mounted on the vehicle-mounted lifting mechanism 3. This mechanism includes a multi-axis robotic arm 7, a vertical-vertical integrated power mechanism, and a horizontal movement mechanism. The nozzle 5 is mounted on the multi-axis robotic arm 7. The horizontal movement mechanism drives the multi-axis robotic arm 7 to move laterally, and its driving direction is parallel to the vertical wall. The vertical-vertical integrated power mechanism drives the multi-axis robotic arm 7 to move vertically and longitudinally. This mechanism includes a vertical-vertical integrated frame 8, a vertical-vertical integrated movement module, and a vertical-vertical integrated guide structure. The vertical-vertical integrated guide structure includes a vertical-vertical integrated guide rod 9, which comprises a vertical section, a curved section, and a longitudinal section. The vertical section is connected to the bottom of the curved section, and the longitudinal section is connected to the top of the curved section. The vertical-vertical integrated movement module moves on the vertical-vertical integrated guide rod 9, realizing the vertical and longitudinal movement of the multi-axis robotic arm 7.

[0023] Combination Figures 1-3The vertical and vertical integrated power mechanism is set on the horizontal moving power mechanism. The vertical and vertical integrated moving module includes a vertical and vertical integrated moving base 10, a vertical and vertical integrated moving roller 11, a vertical and vertical integrated power motor 12, and a vertical and vertical integrated transmission structure. The vertical and vertical integrated moving roller 11 is rotatably connected to the vertical and vertical integrated moving base 10. The vertical and vertical integrated moving roller 11 is provided in multiple sets, and each set includes two vertical and vertical integrated moving rollers 11 arranged opposite each other. The vertical and vertical integrated guide rod 9 is clamped between the two vertical and vertical integrated moving rollers 11 in the same set. The vertical and vertical integrated power motor 12 is fixedly set on the vertical and vertical integrated frame 8.

[0024] The vertical and vertical integrated transmission structure includes a vertical and vertical integrated belt 15 and multiple vertical and vertical integrated pulleys. The vertical and vertical integrated moving seat 10 is fixedly connected to the vertical and vertical integrated belt 15. Through the above structure, by using multiple sets of relatively arranged moving rollers to clamp the guide rod, the stability and guiding accuracy of the moving module during transitions in the vertical, curved, and longitudinal sections are ensured, effectively preventing swaying and deviation during climbing or turning.

[0025] Combination Figures 1-3 The vertically and vertically integrated moving rollers 11 are provided in four sets, of which the axial direction of two sets of vertically and vertically integrated moving rollers 11 is perpendicular to the axial direction of the other two sets of vertically and vertically integrated moving rollers 11. This enhances the adaptability and stability in curved sections, making the movement trajectory of the spray head 5 continuous and smooth when switching between the wall and the ceiling, and ensuring the uniformity and consistency of the spraying process.

[0026] Combination Figures 1-3 The vertical and vertical integrated guide rods 9 are provided in two parallel horizontally, with two sets of vertical and vertical integrated moving rollers 11 clamped on one of the vertical and vertical integrated guide rods 9, and the other two sets of vertical and vertical integrated moving rollers 11 clamped on the other vertical and vertical integrated guide rod 9.

[0027] Combination Figures 1-2 The lateral movement mechanism includes a lateral drive motor 13 and a lateral transmission assembly; the lateral transmission assembly includes a lateral lead screw 14 and a lateral lead screw nut, and the lateral lead screw nut is fixedly connected to the vertical and longitudinal integrated frame 8.

[0028] Combination Figures 1-3 The working principle of the above-mentioned intelligent construction device for indoor wall spraying is as follows: First, add sufficient paint to the paint tank 6 inside the spraying frame 1 to ensure reliable sealing between the paint delivery pipe and the nozzle 5 and paint tank 6, and avoid leakage during the spraying process. Then, use the spraying trolley to move the entire device to the indoor area to be sprayed, and complete the initial positioning according to the position of the surface to be sprayed (vertical wall or ceiling), laying the foundation for subsequent precise spraying.

[0029] Set the spraying parameters, such as the horizontal length and vertical height of the wall or the length and width of the ceiling, as well as the spraying flow rate and spraying speed, before starting the actual spraying operation.

[0030] When horizontal spraying is required, the multi-axis robotic arm 7 is driven by the horizontal movement force mechanism to move smoothly horizontally. The spraying unit starts simultaneously, and the paint in the paint tank 6 is stably delivered to the nozzle 5 through the paint delivery pipe under the action of the conveying power. The nozzle 5 atomizes the paint under the preset pressure and sprays it evenly. Through the preset movement stroke and speed, the horizontal area of ​​the vertical wall or ceiling is fully covered, avoiding spraying dead corners. At the same time, the multi-axis robotic arm 7 adjusts the posture of the nozzle 5 and the distance between it and the spraying surface in real time according to the flatness of the surface to be sprayed and the required spraying angle, ensuring that the nozzle 5 always sprays at the optimal angle and improves the uniformity of spraying.

[0031] When vertical spraying is required, the vertical and vertical integrated moving module smoothly rises or falls along the vertical section of the guide rod, driving the multi-axis robotic arm 7 and the nozzle 5 to move vertically, and cooperating with the horizontal movement to achieve full-area spraying of the wall. When it is necessary to switch to ceiling spraying, the vertical and vertical integrated moving module first rises to the top along the vertical section, and after a smooth transition through the curved section, it switches to the vertical section. At this time, the multi-axis robotic arm 7 drives the nozzle 5 to turn towards the ceiling, completing the seamless switch between vertical and vertical spraying directions.

[0032] Furthermore, when the spraying height is relatively high or when the ceiling needs to be sprayed, the vehicle-mounted lifting mechanism 3 inside the spraying vehicle frame 1 is activated, driving the entire position control mechanism to lift as a whole. When spraying vertical walls, the working height can be adjusted according to the wall height; when spraying ceilings, the position control mechanism is raised to a preset height close to the ceiling to ensure that the nozzle 5 can cover the entire height range of the area to be sprayed.

[0033] Once one area is finished being painted, the spraying wheel 2 can be used to move to the next area to be painted, and the height adjustment, position control and painting process described above can be repeated until the painting of all target areas in the room is completed. The entire process does not require manual handling of the spray nozzle 5, thus achieving automated and intelligent painting.

[0034] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
