Sichuan Shanyueliang Agricultural Technology has applied for a patent for a remote-controlled spray painting robot that incorporates path planning to prevent the outermost layer of paint from bouncing back onto other areas of the workpiece due to collisions.
According to information from the National Intellectual Property Administration, Sichuan Shanyueliang Agricultural Technology Co., Ltd. and Chengdu Qisui Environmental Technology Co., Ltd. have submitted a patent application titled “A Remote-Controlled Spray Painting Robot with Path Planning and a Spray Method“, published under CN121696055A, with an application date of February 2026. The patent abstract indicates that this invention relates to the field of spraying technology and includes a linear drive module. The positioning seat is equipped with an air intake adjustment component, and a telescopic movable part is installed on the outside of the suction pipe.
The invention utilizes an air intake adjustment component, which is driven by a second motor to rotate a distance-adjusting screw, allowing a slider to move along a limiting guide rail. This positioning enables the suction pipe to be located at the outermost side where the spray nozzle emits paint. When the spray nozzle releases paint, the first motor is activated, driving the rotation of the first gear to cause the rotating gear ring to turn. This allows the annular active chamber to rotate relative to the annular positioning chamber, facilitating the extraction of the paint around the emitted area. Additionally, the suction pipe rotates around the nozzle’s center, enabling it to create a circular suction around the emitted paint, thereby preventing the outermost paint from bouncing back onto other areas of the workpiece due to collisions.
Data from Tianyancha indicates that Sichuan Shanyueliang Agricultural Technology Co., Ltd. was established in 2023 in Chengdu and primarily engages in technology promotion and application services. The registered capital of the company is 2 million RMB. Analysis from Tianyancha shows that the company has three trademark records and five patent records, along with one administrative license.
Chengdu Qisui Environmental Technology Co., Ltd., established in 2022 in Chengdu, also focuses on technology promotion and application services, with a registered capital of 1 million RMB. Tianyancha’s data analysis shows that the company has one patent record and one administrative license.
