Description

Technical Field

[0001] The invention relates to the technical field of automobile parts spraying, and in particular to a spraying device for surface treatment of automobile parts. Background Art

[0002] Spraying technology plays an important role in the field of automobile manufacturing and maintenance. It not only adds beauty to the car, but also protects the car body from external factors. Automobile spraying is a complex and precise process involving many processes and principles. One of the purposes of spraying auto parts is to provide auto parts with a protective coating to prevent the parts from being affected by corrosion and oxidation. The car encounters air resistance during driving, and the faster the speed, the greater the resistance. Auto parts shark fins can reduce the effect of air resistance on the vehicle. Even though many vehicles are now equipped with special spoilers, shark fins still play a good spoiler role.

[0003] After the shark fin is processed, its surface needs to be painted to improve the surface performance and aesthetic performance of the shark fin. The shark fin needs to be fixed during the spraying process. At the same time, in order to allow the paint to adhere well to the surface of the shark fin, the surface of the shark fin needs to be polished to make it smooth, thereby improving the quality of the shark fin after spraying. However, the spraying device on the current market cannot stably fix the shark fin during the spraying process, and cannot shield the bottom of the shark fin after fixation, causing the installation bottom of the shark fin to be sprayed with paint, resulting in the isolation of the paint during the subsequent installation process, affecting the shark fin glue on the car, reducing the spraying The quality of the shark fin is affected. At the same time, the current spraying adopts all-round large-area spraying, and the spraying area cannot be adaptively changed according to the shape of the shark fin, resulting in a part of the paint cannot be fully sprayed on the shark fin, causing some paint waste. At the same time, the spraying device before grinding cannot pre-grind the surface of the shark fin. The shark fin needs to be manually placed on the grinding mechanism for grinding, resulting in low spraying efficiency for the shark fin. At the same time, due to the curved outer surface of the shark fin, it is difficult to fully fit and grind the surface of the shark fin during the grinding process, resulting in poor grinding effect, which leads to poor subsequent spraying effect on the shark fin surface.

[0014] Beneficial effects of the present invention: (1) The shark fin of an automobile part is placed on a discharge frame, and then the shark fin is flexibly fixed by a loading and unloading machine on the discharge frame. After being fixed, the fixed shark fin is driven to rotate to a surface treatment mechanism for grinding its surface. After the treatment, it is sprayed by a spraying mechanism, and after spraying, its surface is dried, thereby realizing the integrated treatment of grinding, spraying and drying the shark fin surface, which greatly improves the spraying efficiency of the shark fin surface.

[0015] (2) The shark fin is placed on the discharge frame, and the flexible hydraulic fixing bag on the discharge frame is inserted into the shark fin. The shark fin is then flexibly fixed from the inside by the flexible hydraulic fixing bag, and the flexible hydraulic fixing bag is driven to move by the fixing tube to fix the shark fin on the discharge frame, so that the shark fin and the discharge frame are tightly fitted and fixed, so as to prevent the paint from entering the mounting surface at the bottom of the shark fin during the subsequent spraying process, causing the bottom mounting surface to be painted and affecting the subsequent installation of the shark fin.

[0016] (3) The shark fin is covered by the grinding frame, and then the flexible airbag in the grinding frame drives the elastic rubber transmission belt and the first grinding sandpaper to move, and the first grinding sandpaper is attached to the surface of the shark fin according to the shape of the shark fin. Then, the first grinding sandpaper is driven by the elastic rubber transmission belt to move and grind the surface of the shark fin, and the side of the shark fin is grinded in cooperation with the second grinding sandpaper, so that the surface of the shark is fully polished and smooth, which is convenient for the subsequent spraying of the shark fin surface and further improves the spraying effect of the shark fin surface.

[0017] (4) After the surface of the shark fin is polished, the polished shark fin is rotated to the spray mechanism position, and then the transmission tube, the spray tube and the spray head are driven downward by the seventh electric telescopic rod, so that the spray head on the spray tube sprays the shark fin evenly. At the same time, in the process of moving downward for spraying, the blocking column is driven to move by squeezing the transmission column, and the spraying of the spray head is controlled. When the spray tube moves downward for spraying, as the shark fin gradually becomes smaller, the spraying range of the spray tube is automatically reduced, thereby reducing the waste of spray paint and improving the energy saving and environmental protection of the spraying device.

During the spraying process, as the shark fin gradually becomes smaller, the spraying range of the spray tube 63 is automatically reduced, thereby reducing the waste of spray paint and improving the energy saving and environmental protection of the spraying device. After spraying is completed, the shark fin after spraying is driven to rotate to the drying position. At this time, the hot air blower 71 starts to work, and the hot air is transported to the drying tube 72 through the pipeline, and then the hot air is passed into the drying hood 73 through the drying tube 72. The drying hood 73 dries the surface of the shark fin after spraying, and then rotates to the bottom position for unloading.

[0033] The working principle of the present invention is as follows: by placing the shark fin on the unloading rack 3, and then flexibly fixing the shark fin on the unloading rack 3 through the loading clamping mechanism on the unloading rack 3, and then driving the installation shaft 2 to rotate through the driving mechanism, the installation shaft 2 drives the unloading rack 3 and the shark fin fixed on the unloading rack 3 to rotate to the surface treatment mechanism, and then the surface treatment mechanism performs a comprehensive grinding treatment on the surface of the shark fin. After the grinding treatment is completed, the driving mechanism drives the installation shaft 2 and the unloading rack 3 to rotate again, so that it is transferred to the spraying mechanism position, and the spraying mechanism performs a comprehensive spraying on the surface of the shark fin after the surface treatment, and after the spraying is completed, it is rotated to the position of the hot air blowing mechanism, and then the hot air blowing mechanism dries the surface of the shark fin after spraying, and then drives it to rotate to the bottom for unloading, thereby realizing the integrated treatment of grinding, spraying and drying the surface of the shark fin, and greatly improving the spraying efficiency of the shark fin surface.

[0034] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
