Description

Technical Field

[0001] The utility model belongs to the technical field of building paint spraying, and in particular relates to a spraying robot actuator with variable-width spraying. Background Art

[0002] When a traditional architectural paint spraying robot is in operation, the spraying trajectory is fan-shaped. Due to limitations such as its freedom of movement and motion trajectory planning, the architectural paint sprayed onto the wall or ceiling presents a fixed width on the wall. When the width of the wall or ceiling waiting to be sprayed is not an integer multiple of the spray width, the robot can only deal with it by increasing the overlap width or giving up spraying, and the spray width cannot be changed. This treatment method will result in uneven paint thickness on the wall and ceiling waiting to be sprayed, affecting the flatness. At the same time, if the wall width is less than the fixed spray width, the sprayed architectural paint will splash out of the spraying position and cause pollution to other finished surfaces. Therefore, we propose a spray robot actuator with variable width spraying to solve the above problems. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a spray robot actuator with variable width spraying, which solves the problem that the spray width cannot be changed.

[0004] The utility model is realized by the following scheme: a spraying robot actuator with variable width spraying, comprising:

[0005] Spraying assembly, the spraying track is fan-shaped, used for spraying paint on the surface to be sprayed;

[0006] a first adjusting assembly, the first adjusting assembly comprising a first motor, the spraying assembly being connected to a first output shaft of the first motor;

[0007] a second adjusting assembly, the second adjusting assembly comprising a second motor, the first adjusting assembly being connected to a second output shaft of the second motor, and the first output shaft and the second output shaft being perpendicular to each other;

[0008] a third adjusting assembly, wherein the third adjusting assembly includes a third motor connected to the spraying robot, the second adjusting assembly is connected to a third output shaft of the third motor, and the second output shaft and the third output shaft are perpendicular to each other;

[0009] The third adjustment component also includes a connecting plate fixed on the spraying robot and a roller connected to the third output shaft of the third motor. The third motor is fixed on the connecting plate, and the roller is rotatably connected to the connecting plate; the third output shaft is fixed to the roller through an external kit, and the second adjustment component is connected to the outside of the roller.

[0010] A further improvement of the variable width spraying spray robot actuator of the present utility model is that it also includes a connecting shaft arranged between the second adjusting component and the roller and used to support the second adjusting component at a certain basic distance from the roller. The first end of the connecting shaft is vertically fixed to the outer circumference of the roller, and the second end is connected to the second adjusting component.

[0011] A further improvement of the variable width spraying spray robot actuator of the present invention is that the second adjustment component also includes a transmission component, and the transmission component includes a driving wheel fixed to the second output shaft of the second motor, a driven wheel connected and fixed to the first adjustment component, and a transmission belt wrapped around the outer periphery of the driving wheel and the driven wheel.

[0012] A further improvement of the variable width spraying spray robot actuator of the present invention is that the transmission assembly further includes a tensioning wheel for adjusting the tension of the transmission belt.

[0013] A further improvement of the variable width spraying spray robot actuator of the present invention is that the second adjustment component further includes a shell connected and fixed to the second end of the connecting shaft, which is used to cover the second motor and the transmission component.

The entire adjustment process is convenient and fast, which is beneficial to construction and improves efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to solve the problem of being unable to change the spray width, the present invention provides a spray robot actuator for variable width spraying. The following is a further description of the spray robot actuator for variable width spraying using a specific embodiment in conjunction with the accompanying drawings.

[0025] See Figures 1 to 6 As shown, a spray robot actuator for variable width spraying includes:

[0026] A spraying assembly, the spraying track is fan-shaped, and is used to spray paint on the spraying surface 10;

[0027] A first adjustment component 5, the first adjustment component 5 includes a first motor, and the spraying component is connected to a first output shaft of the first motor;

[0028] The second adjustment component 4 includes a second motor 401, wherein the first adjustment component is connected to the second output shaft of the second motor, and the first output shaft and the second output shaft are perpendicular to each other;

[0029] The third adjustment component 3 includes a third motor 302 connected to the spraying robot 1, the second adjustment component is connected to the third output shaft of the third motor, and the second output shaft and the third output shaft are perpendicular to each other;

[0030] The third adjustment component 3 also includes a connecting plate 2 fixed on the spraying robot 1 and a roller 301 connected to the third output shaft of the third motor 302. The third motor 302 is fixed on the connecting plate 2, and the roller 301 is rotatably connected to the connecting plate 2; the third output shaft is fixedly connected to the roller 301 through an external kit, and the second adjustment component 4 is connected to the outside of the roller 301.

[0031] Specifically, the first adjustment component 5 also includes a shell that covers the first motor, which is used to shield the first motor to prevent it from being exposed, thereby achieving a beautifying effect. Through the adjustment of the spraying component by the first adjustment component 5, the second adjustment component 4 and the third adjustment component 3, when the spraying robot 1 encounters surfaces 10 to be sprayed with different widths, the coverage rate and spraying uniformity of the surface 10 to be sprayed can be improved, and the material waste rate and cross contamination during the construction process of the spraying robot 1 can be reduced; the first motor, the second motor 401 and the third motor 302 are all frameless torque motors.

[0032] Among them, see Figure 1 As shown, it also includes a connecting shaft 9 arranged between the second adjusting component 4 and the roller 301 and used to support the second adjusting component at a certain basic distance from the roller. The first end of the connecting shaft 9 is vertically fixed to the axial direction of the roller 301, and the second end is connected to the second adjusting component 4.

[0033] Through the setting of the connecting shaft 9, the second adjusting component 4 and the roller 301 can be connected and fixed and maintain a certain basic distance. When the roller 301 rotates, the second adjusting component 4 can be driven to rotate through the connecting shaft 9 to meet the distance adjustment between the spraying component and the surface to be sprayed 10.

[0034] Among them, see Figure 1-3 As shown, the second adjustment assembly 4 further includes a transmission assembly, which includes a driving wheel 403 fixed to the second output shaft of the second motor 401, a driven wheel 404 connected and fixed to the first adjustment assembly 5, and a transmission belt 405 wound around the outer circumference of the driving wheel 403 and the driven wheel 404;

[0035] The transmission assembly also includes a tensioning pulley 406 for adjusting the tension of the transmission belt 405;

[0036] The second adjustment component 4 also includes a shell 402 connected and fixed to the second end of the connecting shaft 9, which is used to cover the second motor 401 and the transmission component; specifically, the shell 402 is connected and fixed to the connecting shaft 9; the shell 402 adopts the above design to play a shielding role and has a beautifying effect.

[0037] Specifically, the tensioning wheel is fixed in the shell, and the tensioning force of the transmission belt 405 can be adjusted by setting the tensioning wheel 406. The structure of the tensioning wheel and how to achieve tensioning belong to the existing technology and will not be elaborated here. By starting the second motor 401, the driving wheel 403 can be driven to rotate, and then the driven wheel 404 is driven to rotate through the transmission belt 405, so as to drive the first adjustment component 5 to rotate and adjust the elevation angle of the spraying component.

[0038] Among them, see Figure 1 As shown, the spraying assembly includes a connecting seat 6 fixed on the first output shaft of the first motor, a spray gun 7 fixed on the connecting seat 6 and a nozzle 8 arranged on the spray gun 7.

[0039] By starting the first motor to drive the connecting seat 6 to rotate an angle, the spray gun 7 can drive the nozzle 8 to rotate an angle, which is easy to adjust and use.

[0040] When the spraying robot 1 is working, when the width of the surface 10 to be sprayed is greater than the fixed spray width, the fixed spray width is used for spraying operation, such as Figure 4 As shown, at this time, the angle of the nozzle 8 is horizontal, the distance between the nozzle 8 and the surface to be sprayed 10 is L1, and the spray width is W1;

[0041] The distance between the nozzle 8 and the surface to be sprayed 10 can be adjusted by the second adjustment component 4 and the third adjustment component 3, thereby changing the spray width of the nozzle 8. Figure 5 As shown, the distance between the nozzle 8 and the surface to be sprayed 10 is L2, and the spray width is W2;

[0042] When encountering a surface 10 to be sprayed or a blank area with a spray width smaller than the fixed spray width, the nozzle 8 is tilted to adjust the spray angle to an angle θ with the horizontal, such as Figure 6 As shown, the distance between the nozzle 8 and the surface to be sprayed 10 is L3, and the spray width at this time is the fixed spray width×cosθ, which is W3.
