Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an integrated device for pretreatment and automatic loading and unloading of spraying. Background Art

[0002] The pretreatment system is a crucial link in the spraying process of automobile parts. It is mainly used to remove impurities such as oil stains, dust, and rust on the surface of workpieces, and provide a good foundation for the adhesion of subsequent coatings. Among them, the phosphating process is a surface treatment technology mainly used for the surface of automobile metal parts to improve their corrosion resistance and coating adhesion.

[0003] The phosphating process involves forming a layer of phosphate film on the metal surface. This layer of film can be amorphous or crystalline, depending on the phosphating agent and treatment conditions used. When phosphating automobile parts, it is often manual to sequentially place the workpieces to be phosphated into various soaking tanks for reaction or cleaning, resulting in a relatively high labor intensity for workers.

[0004] In view of the above problems, the utility model document proposes an integrated device for pretreatment and automatic loading and unloading of spraying. Summary of the Utility Model

Below the truss, there are successively arranged from front to back a placement rack for storing automobile parts to be phosphated, a plurality of soaking tanks for carrying out the phosphating process, and an electric conveyor belt for conveying the phosphated workpieces to the spraying chamber;

[0009] A loading and unloading component, arranged on the truss, for reducing the labor intensity of workers;

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] The working principle and usage process of this technical solution are as follows:

[0018] In use, the worker places the automotive parts to be phosphated on the placement rack and easily moves it to the front end of the equipment by using the universal wheels at the bottom of the placement rack. Start the loading and unloading component, the first driving motor drives the threaded rod to rotate, driving the sliding seat to move horizontally along the truss to the designated position. The electric push rod extends, lowering the pneumatic suction cup above the placement rack, and the high-definition camera assists in precisely aligning the workpiece to be taken. The pneumatic suction cup is activated, and after adsorbing the workpiece, the electric push rod contracts to lift the workpiece above the truss. The sliding seat continues to move above the soaking tank, and the electric push rod extends again to place the workpiece into the soaking tank in sequence for phosphating treatment (cleaning, first water wash, surface adjustment, phosphating, and second water wash). When the workpiece is in the soaking tank, a heating rod is used to maintain an appropriate temperature, and the temperature sensor monitors in real time and feeds back to the temperature controller for adjustment. The second driving motor drives the stirring blade to rotate, making the liquid in the tank mix evenly, improving the phosphating effect. The hollow protective cover protects the surface of the workpiece from being worn by the stirring blade;

[0019] After phosphating is completed, repeat the above steps to take out the workpiece from the soaking tank and move it to the center of the air-drying component. Two rows of eight-shaped inclined air-drying fans are activated to quickly air-dry the surface of the workpiece. Finally, the air-dried workpiece is placed on the electric conveyor belt and continues to be conveyed along the electric conveyor belt to the spraying chamber for the next treatment.

[0020] The utility model has the following beneficial effects:

[0021] Through the automated design of the loading and unloading component and the air-drying component, the utility model significantly reduces the labor intensity of workers, improves production efficiency, and uses a high-definition camera to assist in alignment to ensure accuracy during the loading and unloading process of workpieces, reducing errors and damage.

[0022] In the utility model, the combined use of the heating rod and the stirring blade keeps the liquid in the tank at an appropriate temperature and mixes evenly, improving the phosphating effect and quality.

[0023] Through the integrated design, the utility model realizes the automation and high efficiency of the phosphating treatment of automotive parts, significantly reduces the labor intensity of workers, and improves production efficiency and product quality. BRIEF DESCRIPTION OF THE DRAWINGS
