[0023] The following further describes this application in detail in conjunction with the attached Figure 1-2 drawings.

[0024] An embodiment of this application discloses an automatic indoor wall grinding device. Refer to Figure 1 and Figure 2 , an automatic indoor wall grinding device includes a mobile vehicle 1 and a grinding assembly 2. The grinding assembly 2 includes an extension piece 21, a bracket 22 and a grinding piece 23. One end of the extension piece 21 is connected to the mobile vehicle 1 and the other end is connected to the bracket 22. A support plate 3 is arranged on the bracket 22, the grinding piece 23 is arranged on the support plate 3, a dust suction pipe 4 is arranged on the support plate 3, a guide ring 41 is coaxially connected to the dust suction pipe 4, and the guide ring 41 is inclined towards the axis direction of the dust suction pipe 4. And the dust suction pipe 4 covers the outside of the grinding piece 23, and a collection assembly 5 matching the dust suction pipe 4 is arranged on the mobile vehicle 1. After the mobile vehicle 1 moves the grinding assembly 2 to the set position, the grinding piece 23 can grind the wall. During the operation of the grinding piece 23, the guide ring 41 provides guidance for the dust, so that the dust enters the dust suction pipe 4 more stably, and the collection assembly 5 collects the dust, reducing the possibility of dust overflow. On the one hand, it provides convenience for the subsequent wall painting, and on the other hand, it improves the stability of the grinding device during use.

[0025] Refer to Figure 1 , the mobile vehicle 1 is set as an AGV cart in the embodiment of this application. The extension piece 21 includes a robotic arm. One end of the robotic arm is connected to the mobile vehicle 1 and the other end is connected to the bracket 22. The robotic arm can be set as a three-axis, four-axis, five-axis or six-axis robotic arm, and the specific model is determined according to the actual working conditions.

[0026] Refer to Figure 1 and Figure 2, the collection component 5 includes a fan 51 and a collection box 52. The fan 51 is fixed on the mobile vehicle 1. One end of the fan 51 is connected to the collection box 52 through a connecting pipe 511, and the other end is connected to a collection pipe 512. A plurality of dust removal pipes 42 are connected to the dust suction pipe 4, and one end of each dust removal pipe 42 away from the dust suction pipe 4 is connected to the collection pipe 512. And in order to reduce the possibility of dust affecting the grinding part 23, a plurality of dust falling holes 43 are provided on one side of the dust suction pipe 4 close to the grinding part 23.

[0027] During the operation of the grinding part 23, the fan 51 is started, so that dust enters the dust suction pipe 4, then enters the collection pipe 512 through each dust removal pipe 42, and then enters the collection box 52 through the connecting pipe 511, realizing the function of collecting dust in real time. At the same time, part of the dust falling between the dust suction pipe 4 and the grinding part 23 can re-enter the dust suction pipe 4 from the dust falling holes 43, thereby reducing the phenomenon of dust accumulation between the dust suction pipe 4 and the grinding part 23.

[0028] Refer to Figure 2 , the grinding part 23 includes a motor 231 and a grinding disc 232. The motor 231 is fixed on the support plate 3, the grinding disc 232 is coaxially fixed on the output end of the motor 231, and a sandpaper is bonded to one end of the grinding disc 232 away from the motor 231. And a dust-proof shell 6 is fixed on the support plate 3, and the dust-proof shell 6 covers the motor 231. The dust-proof shell 6 provides protection for the motor 231 and reduces the possibility of dust damaging the motor 231.

[0029] The support plate 3 is slidably connected to the bracket 22, and an electric push rod 221 is fixed on the bracket 22. The output end of the electric push rod 221 is fixed to the support plate 3. A guide plate 222 is fixed on the bracket 22, a guide groove 223 is provided on the guide plate 222, and a guide block 31 is fixed on the support plate 3. The guide block 31 is slidably connected in the guide groove 223. The cooperation between the guide block 31 and the guide groove 223 provides guidance for the movement of the support plate 3, thereby improving the stability of the grinding part 23 during movement.

[0030] After the mobile vehicle 1 moves to the set position, the robotic arm controls the bracket 22 to move to the set position, and the electric push rod 221 controls the support plate 3 to move to control the movement of the motor 231 and the grinding disc 232. After the grinding disc 232 abuts against the wall, the motor 231 is started and drives the grinding disc 232 to rotate, and the wall can be ground.

[0031] Refer to Figure 2, several balls 7 are embedded in the support bracket 22. When it is necessary to provide the grinding assembly 2 with grinding stability, the robotic arm controls the balls 7 on the support bracket 22 to abut against the wall, and then the moving vehicle 1 moves, so that the function of grinding the wall can be realized. At this time, the balls 7 on the support bracket 22 provide support for the grinding assembly 2 on the one hand and change the sliding friction between the support bracket 22 and the wall into rolling friction on the other hand, thereby improving the smoothness of the grinding assembly 2 during operation.

[0032] Referring to Figure 2 , a distance sensor 32 is provided on the support plate 3 to facilitate monitoring the distance between the grinding disc 232 and the wall.

[0033] The implementation principle of an indoor wall automatic grinding device according to an embodiment of the present application is as follows: the moving vehicle 1 controls the grinding assembly 2 to move to a set position, the grinding member 23 grinds the wall, and at the same time, the collection assembly 5 cooperates with the dust suction pipe 4 to collect dust in real time. And the guiding ring 41 guides the dust, so that the dust enters the dust suction pipe 4 more stably, reduces the possibility of dust overflow, and improves the stability of the collection assembly 5 in collecting dust, which provides convenience for the subsequent painting of the wall.

[0034] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
