Description

Technical Field

[0001] The present invention relates to the field of decorative design or advertising, and in particular to a fully automatic wall painting robot. Background Art

[0002] Wall painting is a new technology that, according to relevant requirements, utilizes wall resources of various materials or specifications and sprays fixed shapes with the help of painting cloth or painting film. Compared with traditional hand-painted walls, wall painting has the advantages of low cost, high efficiency, and good visual communication effects, so it is increasingly favored by people and is more and more widely used in the advertising industry, interior decoration industry, etc. However, the existing wall painting machines on the market occupy a large space, not only require manual operation, but also are mainly used for mass production and are not suitable for small-batch personalized painting for individuals.

[0003] Based on this, we draw on the principle of "additive manufacturing" of 3D printing, combine the actual situation of wall painting, simplify three-dimensional positioning to two-dimensional positioning, and design and develop this "fully automatic wall painting robot", which realizes all-round and dead-angle-free painting and greatly liberates human labor. Summary of the Invention

[0004] The purpose of the present invention is to provide a fully automatic wall painting robot to realize the automation and simplification of wall painting. The technical solutions adopted are as follows:

[0005] 1. A fully automatic wall painting robot, characterized in that it includes a moving module, a painting module, and an adsorption module; the moving module includes a chassis frame (1), an omnidirectional wheel chassis (2), omnidirectional wheels (3), and a motor (4); the painting module includes a bottom cover (5), a paint box (6), an inkjet printer (7), a showerhead-type nozzle (8), a nozzle (9), and a paint tube (10); the adsorption module includes a high-pressure air suction pump (11), an air tube (12), and a semi-vacuum low-pressure chamber (13).

[0006] 2. Preferably, three omnidirectional wheels (3) are provided on each omnidirectional wheel chassis (2), and each omnidirectional wheel (3) is driven by an independent motor (4). The beneficial effect is that by controlling the rotation of each motor (4), horizontal and vertical movement is jointly achieved.

[0007] Preferably, four omnidirectional wheel chassis (2) are evenly distributed at the four corners of the chassis frame (1). The beneficial effect is that the stable movement of the entire robot is achieved through the vector combined movement of the four omnidirectional wheel chassis (2).

[0008] Preferably, the ink cartridge (6) is fixed on the bottom cover (5), the inkjet printer (7) is connected to the ink cartridge (6), and the inkjet printer (7) is fixed on the bottom cover (5). The beneficial effect is that during operation, the inkjet printer (7) extracts water-soluble ink from the ink cartridge (6) and uses two methods, namely, the change in the volume of the working chamber and the interaction between the gear blades and the ink, to achieve double pressurization and transport the ink to the showerhead (8).

[0009] Preferably, each of the nine nozzles (9) on the showerhead (8) is equipped with an independently driven solenoid valve. By separately controlling each solenoid valve through a controller, the spraying and non-spraying of the ink can be achieved, and the spraying of three colors is realized by three ink cartridges (6) and the nozzles (9) arranged in a 3×3 pattern, with one color of ink corresponding to three vertically arranged nozzles (9). The beneficial effect is that the nozzles (9) can achieve separate spraying, so that when the showerhead sweeps once, inks of three colors and three widths can be sprayed, increasing the efficiency and accuracy of spraying.

[0010] Preferably, a small gap is left between the bottom of the semi-vacuum low-pressure chamber (13) and the wall. The beneficial effect is that there is a margin for uneven places on the wall.

[0011] Preferably, there are narrow channels between the multiple diamond-shaped protrusions at the bottom of the semi-vacuum low-pressure chamber (13) and the edge retaining ribs. The beneficial effect is that the channels for air circulation are extended, the entry of air is slowed down, and a semi-vacuum state is formed jointly by the bottom surface of the low-pressure chamber and the hollow part of the low-pressure chamber.

[0012] Compared with the prior art, the full-automatic wall painting robot of the present invention has the following features and advantages:

[0013] 1. The present invention can paint patterns of any shape and any thickness on the wall, meeting people's different painting needs, realizing the function of painting various-shaped patterns on one product, and completing the "personalized customization" in the painting industry.

[0014] 2. The present invention organically combines the flexibility of a wall-climbing robot and the practicality of an ordinary large-scale painting machine, enabling the painting device to move freely on the wall surface, integrating flexibility, convenience, high efficiency and practicality.

[0015] 3. The three-legged universal wheels of the present invention can move in all directions along the wall under the drive of a motor, and the high-pressure suction pump can fix the painting robot on the wall surface for painting under the action of a pressure difference.

[0023] Among them, it includes a chassis frame (1), an omnidirectional wheel chassis (2), omnidirectional wheels (3), motors (4), a bottom cover (5), a paint box (6), an inkjet printer (7), a shower head type nozzle (8), nozzles (9), paint tubes (10), a high-pressure suction pump (11), air pipes (12), and a semi-vacuum low-pressure chamber (13). Specific implementation manners

[0024] As Figure 1 shown, the fully automatic wall painting robot includes a chassis frame (1), an omnidirectional wheel chassis (2), omnidirectional wheels (3), motors (4), a bottom cover (5), a paint box (6), an inkjet printer (7), a shower head type nozzle (8), nozzles (9), paint tubes (10), a high-pressure suction pump (11), air pipes (12), and a semi-vacuum low-pressure chamber (13).

[0025] Refer to Figure 1 , three omnidirectional wheels (3) are arranged on each omnidirectional wheel chassis (2), and each omnidirectional wheel (3) is driven by an independent motor (4). By controlling the rotation of each motor (4) respectively, the lateral and longitudinal movements are jointly achieved.

[0026] Refer to Figure 1 , four omnidirectional wheel chassis (2) are evenly distributed at the four corners of the chassis frame (1).

[0027] Refer to Figure 1The pigment box (6) is fixed on the bottom cover (5), the inkjet machine (7) is connected to the pigment box (6), and the inkjet machine (7) is fixed on the bottom cover (5). When working, the inkjet machine (7) extracts water-soluble pigment from the pigment box (6), and realizes double pressurization by using the change of the volume of the working chamber and the interaction between the gear blade and the pigment, so as to transport the pigment to the shower-type nozzle (8).

[0028] Reference Figure 1 The nine nozzles (9) on the shower-type nozzle (8) are each equipped with an independently driven electromagnetic valve. The controller controls each electromagnetic valve individually to realize spraying or not spraying the pigment. The three pigment boxes (6) and the nozzles (9) arranged in 3*3 are used to realize spraying of three colors. One pigment corresponds to three vertical nozzles (9). The nozzles (9) can realize independent spraying, so that the shower-type nozzle can spray three colors and three widths of pigments in one sweep, thereby increasing the efficiency and accuracy of spraying.

[0029] Reference Figure 3 , two high-pressure suction pumps (11) are fixed on the shell of the semi-vacuum low-pressure chamber (13), and the high-pressure suction pump (11) and the semi-vacuum low-pressure chamber (13) are connected through the air pipe (12). A small gap is left between the bottom of the semi-vacuum low-pressure chamber (13) and the wall, in order to leave a margin for the uneven places on the wall; the presence of multiple diamond-shaped protrusions and edge ribs at the bottom of the semi-vacuum low-pressure chamber (13) and the narrow and long channel in the middle of the semi-vacuum low-pressure chamber (13) prolongs the air circulation channel, slows down the entry of air, and makes the bottom surface and the hollow part form a semi-vacuum state together. The high-pressure suction pump (11) at the top of the semi-vacuum low-pressure chamber (13) draws out the air in the room and blows it out vertically, generating a certain reaction force on the robot. Therefore, the robot realizes the adsorption function by means of the pressure difference (mainly) inside and outside the semi-vacuum low-pressure chamber (13) and the reaction force of the jet (auxiliary).

[0030] A fully automatic wall painting robot, the operation process of which is as follows:

[0031] Step 1: The user first scans the spray painting pattern to the fully automatic wall spray painting robot through the USB interface;

[0032] Step 2: The user sets the corresponding spray painting thickness on the touch screen according to personal needs. Then, the fully automatic wall spray painting robot is placed at a suitable position on the wall. The power button is pressed, and the adsorption module fixes it on the wall under the action of pressure difference.

[0033] Step 3: The fully automatic wall painting robot moves according to the pre-set pattern with the help of universal wheels, moves to the corresponding position, and sprays the paint of the set thickness with the shower-type nozzle to complete the entire painting process;

[0034] Step 4: After the spraying is completed, the buzzer will give an automatic reminder, and the spraying work will officially end.

[0035] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
