Description

Technical Field

[0001] This invention relates to the field of building vibration isolation, and specifically to an automatic spraying robot for noise-reducing and damping coatings. Background Technology

[0002] Waterborne damping coatings are a new type of environmentally friendly coating with high damping performance, using waterborne resin as the main film-forming substance and inorganic or organic substances as fillers. They do not contain toxic solvents. Waterborne damping coatings can convert absorbed vibration energy into heat energy by utilizing the viscoelastic properties of polymer materials, thereby reducing noise and vibration. Because waterborne damping coatings also have advantages such as corrosion resistance, aging resistance, high adhesion, convenient storage, low cost, and safety and environmental friendliness, they have been widely used in automobiles, trains, ships, airplanes, engineering machinery, large-scale construction facilities, and interior decoration.

[0003] In building noise reduction and vibration reduction, in order to achieve good vibration reduction and noise reduction effects, it is necessary to spray water-based damping coatings, which have vibration reduction and noise reduction functions, on the inner side walls and inner ceiling walls of the building. Although there are many spraying equipment on the market, these spraying equipment only play an auxiliary role.

[0027] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0028] See Figures 1-7 The automatic spraying robot for noise-reducing damping coating of the present invention includes a mobile vehicle body 1, a storage device 2 for storing damping coating disposed on the mobile vehicle body 1, a spraying device, and a conveying device 3 for conveying the damping coating in the storage device 2 to the spraying device. The conveying device 3 is a conveying pump; the storage device 2 is a storage tank; the inlet of the conveying pump is connected to the outlet of the storage tank; and the outlet of the conveying pump is connected to the nozzle 5 through a conveying pipe.

[0029] See Figures 1-7 The spraying device includes a spraying mechanism and a spraying angle adjusting mechanism for adjusting the spraying angle of the spraying mechanism, wherein,

[0030] The spraying mechanism includes a bracket 6 and nozzles 5 mounted on the bracket 6. The bracket 6 includes a first rod 6-1 and a second rod 6-2 perpendicularly connected to the first rod. The spraying mechanism also includes a position adjustment mechanism for adjusting the position of the nozzles 5. The position adjustment mechanism includes a drive motor 7 mounted on the first rod 6-1 of the bracket 6 and a lead screw transmission mechanism 13. The lead screw transmission mechanism 13 includes a lead screw and a lead screw nut that cooperates with the lead screw. The lead screw is mounted on the first rod 6-1 of the bracket 6, and the nozzles 5 are mounted on the lead screw nut. The drive motor 7 is connected to the lead screw. The drive motor 7 drives the lead screw to rotate, thereby driving the lead screw nut to move linearly, thus adjusting the position of the nozzles 5, thereby enabling spraying of various locations on the ceiling, side walls, and floor of the building.

[0031] The spraying angle adjustment mechanism is used to drive the first rod 6-1 of the bracket 6 to move to a vertical or horizontal state, so as to spray the ceiling, side walls and floor of the house. The spraying angle adjustment mechanism includes a frame 4 mounted on the mobile vehicle body 1, a fixed rack guide rail mounted on the frame 4, a movable rack guide rail, and a transverse drive mechanism 12 for driving the movable rack guide rail to move laterally. The fixed rack guide rail includes a first linear rack guide rail 8 and a first arc rack guide rail 9. The first linear rack guide rail 8 is vertical. The first linear rack guide 8 is vertically positioned, with its lower end connected to the first arc rack guide 9. The movable rack guide includes a mounting plate 17, a second linear rack guide 11, and a second arc rack guide 10 mounted on the mounting plate 17. The second linear rack guide 11 is vertically positioned. The transverse drive mechanism 12 drives the mounting plate 17 to move, thereby enabling the second arc rack guide 10 to connect with the first arc rack guide 9, or the second linear rack guide 11 to connect with the first arc rack guide 9.

[0032] The second rod 6-2 of the bracket 6 is provided with a gear 14 and a rotary motor 15 for driving the gear 14 to rotate. There are two sets of gears 14, both sets of gears 14 are rotatably connected to the second rod 6-2 of the bracket 6, and both are engaged with the fixed rack guide or the movable rack guide. The distance between the two sets of gears 14 is equal to the diameter of the first arc rack guide 9 and the second arc rack guide 10.

[0033] In this embodiment, the first circular arc rack guide 9 and the second circular arc rack guide 10 have the same radius, wherein the arc of the first circular arc rack guide 9 is 180 degrees and the arc of the second circular arc rack guide 10 is 90 degrees.

[0034] The above settings offer the following advantages:

[0035] (1) When the two sets of gears 14 on the second rod 6-2 of the bracket 6 are located on the first linear rack guide rail 8 of the fixed rack guide rail, the spraying mechanism is in a horizontal state and the nozzle 5 is facing upward; thus, the interior ceiling wall of the house is sprayed. At the same time, the gears 14 are rotated by the rotary motor 15, so that the bracket 6 makes a linear lifting and lowering motion on the first linear rack guide rail 8, thereby adjusting the height of the spraying mechanism when spraying the interior ceiling wall of the house.

[0036] (2) During the process of the two sets of gears 14 on the second rod 6-2 of the bracket 6 moving from the first linear rack guide 8 to the first circular arc rack guide 9, since the distance between the two sets of gears 14 is equal to the diameter of the first circular arc rack guide 9 and the second circular arc rack guide 10, when the drive gear 14 (i.e. the gear 14 connected to the rotary motor 15) enters the first circular arc rack guide 9, it can move around the first circular arc rack guide 9. When the two sets of gears 14 are respectively located at the two ends of the first circular arc rack guide 9 (since the first circular arc rack guide 9 is 180 degrees), the spraying mechanism is in a vertical state, and the orientation of the nozzle 5 is the same as (or opposite to) the movement direction of the moving vehicle 1, and cooperates with the movement of the moving vehicle 1 to achieve spraying of the inner wall of the house. During the process of the first rod 6-1 of the aforementioned bracket 6 rotating from a horizontal state to a vertical state, it is equivalent to simultaneously rotating around the midpoint between the two sets of gears 14 in the second rod 6-2 of the bracket 6 and the center of the first arc rack guide rail 9. This allows the first rod 6-1 of the bracket 6, which is now in a vertical state, to extend beyond the edge of the moving vehicle 1. This places the first rod 6-1 of the bracket 6 between the wall of the building and the moving vehicle 1. By controlling the movement of the moving vehicle 1, the distance between the nozzle 5 on the first rod 6-1 of the bracket 6 and the wall can be controlled to meet the spraying distance requirements. Furthermore, since both sets of gears 14 are rotatably connected to the bracket 6 via rotating shafts, and the two sets of gears 14 are connected by a belt drive mechanism 16, in order to adjust the height of the spraying mechanism when spraying the inner wall of the house, the lateral drive mechanism 12 can drive the mounting plate 17 to move laterally, so that the second linear rack guide rail is connected to the first arc rack guide rail 9. Then, the rotary motor 15 drives the belt drive mechanism to move, thereby driving the two sets of gears 14 to rotate, thereby driving the two sets of gears 14 to move up and down on the first linear rack guide rail 8 and the second linear rack guide rail respectively, thus adjusting the height of the spraying mechanism when spraying the inner wall of the house. In the above process, since the spraying direction of the nozzle 5 is parallel to the movement direction of the moving vehicle 1 when spraying the inner wall of the house, the distance between the nozzle 5 and the inner wall of the house can be precisely adjusted by controlling the forward and backward movement distance of the moving vehicle 1.

[0037] (3) When the floor of the house needs to be sprayed, the horizontal drive mechanism 12 drives the mounting plate 17 to move, so that the second arc rack guide rail is connected to the first arc rack guide rail 9. The rotary motor 15 drives the two sets of gears 14 to move, so that the driving gear 14 moves to the end of the second arc rack guide rail, while the other set of gears 14 (i.e., the driven gear 14) moves to the middle position of the first arc rack guide rail 9. At this time, the spraying mechanism is in a horizontal state and the spraying direction is downward, thereby realizing the spraying of the floor of the house. By setting the height of the center position of the first arc rack guide rail 9 and the length of the second rod 6-2 of the bracket 6, when the first rod 6-1 of the bracket 6 is rotated to a horizontal state with the nozzle 5 facing downward, the distance between the nozzle 5 and the ground meets the requirements for spraying.

[0038] It can be seen that by setting the above-mentioned spraying angle adjustment mechanism, not only can the first rod 6-1 of the support 6 be flexibly switched between horizontal upward, vertical and horizontal downward postures, but also the height can be raised and lowered when in the horizontal upward (spraying the ceiling of the house) and vertical (spraying the walls of the house) postures to adapt to the height of the house and spraying at different height positions of the wall. The structure is compact and ingenious.

[0039] See Figures 1-7 The transverse drive mechanism 12 includes a cylinder mounted on the frame 4, and the telescopic rod of the cylinder is connected to the mounting plate 17; a transverse guide mechanism is provided between the mounting plate 17 and the frame 4, and the transverse guide mechanism adopts a structure of a combination of slider and slide rail.

[0040] 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.
