Description

Technical Field

[0001] The utility model belongs to the technical field of automobile part spraying equipment, and particularly relates to a spraying equipment for automobile parts. Background Art

[0002] Automobile part spraying equipment is a kind of equipment used for spraying and processing automobile parts. By spraying paint or protective coating on automobile parts, the aesthetics, corrosion resistance and other properties of automobiles are improved, which is an important step in the production process of automobile parts.

[0003] Automobile part spraying equipment can be divided into: manual spraying equipment, semi-automatic spraying equipment and fully automatic spraying equipment according to different automation levels. Among them, the spraying robot, as a kind of fully automatic spraying equipment, is applied in the production and processing field of automobile parts, and has the advantages of high spraying efficiency, high spraying freedom and high spraying accuracy. During the use of the spraying robot, a conveying assembly line is usually required to automatically convey automobile parts through the conveying assembly line, and the spraying robot sprays and processes the automobile parts conveyed on the conveying assembly line.

[0052] During specific use, the automotive part spraying fixture is fixedly assembled on the fixture loading plate 303. Subsequently, the automotive part is assembled on the spraying fixture. By controlling the operation of the conveying motor 308 to drive the driving roller 305 to rotate, the conveyor belt 301 drives multiple groups of supporting bases 302 to move, and by controlling the movement of the conveyor belt 301, the automotive part moves along with the movement of the conveyor belt 301.

[0053] When the automotive part moves below the spray gun 2, by controlling the operation of the servo motor 407 to drive the lifting screw rod 403 to rotate, the threaded slider 402 drives the assembly rod 401 to move downward under the action of the internal and external threads. The downward movement of the assembly rod 401 drives a pair of exhaust impurity removal pipes 404 to move to the outside of the automotive part. At the same time, compressed gas can be sprayed towards the automotive part along the exhaust impurity removal pipes 404 and the impurity removal nozzles 405 by connecting an external compressed gas source through the air inlet pipe 412, and the impurities adhering to the outside of the automotive part are cleaned by spraying compressed gas.

[0054] Meanwhile, the compressed gas can be sprayed towards the fixture loading plate 303 located below the conveyor belt 301 along the guiding air pipe 410 and the auxiliary impurity removal nozzles 411. The fixture loading plate 303 is assisted in cleaning by spraying compressed gas towards it, reducing the situation where impurities on the fixture loading plate 303 adhere to the automotive part. After cleaning, the automotive part can be spray - painted or coated by spraying paint or coating through the spray gun 2.
