[0003] In the prior art, when an automatic spray robot is spraying, if there are impurities on the surface of the workpiece to be sprayed, it is easy to cause the problem of poor spraying effect on the workpiece surface. At the same time, when in use, the material stored inside the storage box is easy to solidify and cause blockage, which is not conducive to user use.

[0004] In order to overcome the above-mentioned shortcomings, the Chinese patent of the prior art (Announcement No. CN115007359A) discloses an automatic spraying robot, including a base, a spraying platform, a spraying device and a mechanical arm. The spraying platform is arranged on the base to support and fix the ornaments, so as to facilitate the painting operation. The spraying device is connected to the base through a mechanical arm. The automatic spraying robot carries the ornaments to be sprayed through the spraying platform; the mechanical arm drives the spraying device to move relative to the spraying platform, so that the spraying device sprays the ornaments. The automatic spraying robot has mechanized spraying operation and high automated production efficiency; the mechanized spraying operation has high precision, and the equipment can spray the ornaments in large quantities, which improves the finished product rate and good product rate of the ornaments. In addition, a dust cover is provided on the base, and an exhaust hood is connected to one side of the dust cover to avoid interference from dust and other impurities in the automatic painting operation of the ornaments, further improving the quality of the finished ornaments.

When the movable plate moves on the track, the rotating rod drives the rotation of the cam as power output, and cooperates with the interlocking mechanism, so that the stirring ring can reciprocate up and down in the storage barrel at the same time, and the stirring rod rotates in the storage barrel, and at the same time, horizontal force and vertical force are generated inside the storage barrel, so that the stirring of the paint inside the storage barrel is more sufficient and thorough, which is beneficial to the mixing of the paint inside the storage barrel, and at the same time, it can also effectively prevent the paint from solidifying or agglomerating inside the storage barrel.
