Description

Technical Field

[0001] The utility model relates to the field of automobile spraying, in particular to a paint adhesion prevention robot for automobile body spraying. Background Art

[0002] Car spray painting refers to applying a layer of paint on the surface of the car to protect the car. Car spray painting generally uses baking paint. In the car manufacturing plant, after the frame and shell are welded, the next process is spray painting. There are ordinary paint, metallic paint, pearlescent paint. Car spray painting process: scraping putty, grinding, spraying paint, etc.

[0003] However, the mechanical arm used by the spraying robot usually runs too fast, and the spray paint usually sprays out a mist of paint, which causes some of the still floating mist paint to adhere to the mechanical arm when the mechanical arm moves, causing the mechanical arm shell or joints to adhere to and accumulate paint, affecting the normal operation of the machine. Therefore, those skilled in the art provide a paint adhesion prevention robot for automobile body spraying to solve the problems raised in the above background technology. Utility Model Content

[0005] The inner sliding sleeve is equipped with a plurality of rotating rods, the rotating rods are equipped with fans, the rotating rods are fixedly connected with sliding groove rods, the sliding groove rods are slidably connected with sliding block rods, and the sliding block rods are fixedly connected with the outer sliding sleeve.

[0006] Preferably, the inner sliding sleeve is fixedly connected with an inner moving block, the outer sliding sleeve is fixedly connected with an outer moving block, and the nozzle and the inner sliding sleeve are both equipped with a driving screw.

[0007] Preferably, the inner moving block and the outer moving block are both threadedly connected to the driving screw.

[0008] Preferably, the rotating rod is fixedly connected with a fan cover.

[0009] Preferably, the rotating rod is hinged with a hinge seat, and the hinge seat is fixedly connected to the inner sliding sleeve.

[0010] Preferably, the slider rod is composed of a ball and a fixed rod.

[0011] Technical effects and advantages of the utility model:

[0012] When the robot arm drives the nozzle to spray paint, the fan runs at the same time, blowing air in the direction of the nozzle, so that the mist paint can be sprayed onto the car surface faster, avoiding the still floating mist paint adhering to the surface of the robot arm and the nozzle due to the robot arm running too fast, thereby avoiding the accumulation of paint adhering to the casing and joints of the mechanical equipment, ensuring the normal operation of the machine while keeping the mechanical equipment clean and tidy.
