Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spraying robots, in particular to a spraying robot and a spraying method. BACKGROUND

[0002] The spraying robots on the market are divided into two types: air spraying robots and airless spraying robots. The air spraying robot, also known as low-pressure air spraying, relies on low-pressure air to make the paint form an atomized air flow after being sprayed out of the gun nozzle and act on the surface of the object (wall surface or wooden surface). Air spraying has no brush marks compared with hand brushing, the plane is relatively uniform, the unit working time is short, and the construction period can be effectively shortened. However, air spraying has the phenomenon of splashing, resulting in paint waste, and when viewed at close range, very fine particles can be seen. Generally, air compressors commonly used in the decoration industry are used for air spraying, which is relatively multi-purpose and has low investment cost. There are also special machines such as air extraction type air spraying machines and self-falling type air spraying machines on the market.

[0003] However, the existing spraying robots have certain defects. The traditional spraying robot can only use one type of spraying liquid and share one paint bucket, which leads to mixing of the spraying liquids and reduces the spraying effect. At the same time, the traditional spraying usually uses ordinary spraying machines for spraying. The spraying liquid agent sprayed out has large particles, the atomized spraying liquid has a small dispersion range, and once sprayed out, it will quickly fall to the ground and cannot hover in the air for a long time. The spraying liquid agent has a short time limit, resulting in a short spraying time and an unsatisfactory spraying effect. Therefore, a spraying robot and a spraying method are needed to solve the problems in the background art. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a spraying robot and a spraying method, which have the advantages of good spraying effect and large spraying range.

[0008] Further, the steering mechanism comprises a motor mounted on the inner bottom wall of the top groove, the inner side wall of the top groove is provided with a speed reducer box matched with the motor, the output end of the speed reducer box is provided with a steering column, and the top end of the steering column is provided with a base plate.

[0009] Further, the steering column extends to the top of the stand column and is rotationally connected with the stand column, the base plate is a rectangular plate, and the top of the base plate is rotationally mounted with a rear movable seat connected with the air gun through a stand.

[0010] Further, the top of the base plate and located in the front of the rear movable seat is provided with a base groove, and a motorized telescopic rod rotationally mounted in the base groove and rotationally connected with the air gun is arranged.

[0011] Further, the walking part is a remote control intelligent robot, the bottom of the walking part is provided with a driving wheel, and the top of the walking part is provided with a receiving antenna.

[0012] Further, the top of the spraying liquid tank and located at the side of the gas collecting cylinder is fixedly mounted with a supplement pipe, the surface of the supplement pipe is threadedly mounted with a screw cap, the bottom end of the side, away from the walking part, of the spraying liquid tank is fixedly mounted with a discharge pipe, and the surface of the discharge pipe is provided with a valve.

[0013] Further, the atomizer is an ultrasonic ceramic atomizer, a limiting block is fixedly mounted on the top of the stand, a gas conveying pipe is threadedly mounted on the top of the gas collecting cylinder, and the other end of the gas conveying pipe is movably connected with the air gun.

[0014] Another problem to be solved by the present application is to provide a spraying method of the spraying robot, comprising the following steps:

[0015] A, first, different spraying agents are filled into the two spraying liquid tanks;

[0016] B, then, the walking track of the walking part is set through a background operation interface;

[0017] C, the walking part is started, and the forward route is monitored through a monitor, and obstacles are directly bypassed;

[0018] D, in the walking process, the spraying liquid agent is atomized by the atomizer, and the atomized spraying liquid is filled into the gas conveying pipe through the air blower;

[0019] E, the atomized spraying liquid is input into the air gun through the gas conveying pipe, the atomized spraying liquid is blown to the outside by the wind power of the air gun, so that the spraying is realized;

[0020] F, in the running process of the air gun, the angle of the air gun is changed by the motorized telescopic rod according to the operation of the operator, the direction of the air gun is changed by the motor, and then the atomized spraying liquid is blown out in a large area and 360 degrees without dead angle, so that the spraying is realized.

[0021] Compared with the prior art, the present application provides a spraying robot and a spraying method, which have the following

[0022] Advantages:

[0023] The spraying robot and the spraying method of the spraying robot use the ultrasonic ceramic atomizer to rapidly atomize the spraying liquid, and then further spread the atomized spraying liquid to the outside through the air cannon, so that the atomized spraying liquid is in the form of replacing the traditional spraying mechanism, which can make the spraying liquid stay in the air for a long time, increase the time of the spraying liquid, and effectively improve the spraying effect. The motor and the electric telescopic rod can make the air cannon rotate 360 degrees and the spraying angle change randomly, expand the coverage range of the atomized spraying liquid, and further expand the distribution range of the atomized spraying liquid by using the air cannon. Under the same spraying liquid, the spraying range is improved. Finally, different spraying liquids can be selected and put into different spraying liquid tanks, which avoids the problem that multiple spraying liquids share one spraying liquid tank, resulting in mixing of the spraying liquids and reducing the spraying effect. Moreover, by setting two air cannons and two atomizing mechanisms, spraying of the spraying liquid can be carried out through the two air cannons at the same time, which improves the spraying efficiency and ensures that the two kinds of spraying liquids are not mixed, thereby ensuring the spraying effect.
