Description

Method for Automation of Anti-corrosion Process and Anti-corrosion Solution Spraying Device The present embodiments relate to a method for automating a rust prevention process and a rust prevention liquid spraying device, and more specifically, to a method for automating a rust prevention process and a rust prevention liquid spraying device that automates the rust prevention process of a vehicle based on vehicle data and location information. In the automotive industry, metal parts can easily corrode due to environmental conditions, which negatively impacts vehicle performance and lifespan. In particular, vehicle exterior panels, underframes, chassis, and various engine components are highly susceptible to corrosion due to exposure to moisture, salt, and chemicals. Anti-corrosion processes are recognized as essential for preventing such corrosion and ensuring the durability and safety of vehicles, and anti-corrosion treatment aims to maximize the corrosion prevention effect by uniformly applying an anti-corrosion liquid to the metal surface. However, existing anti-corrosion processes generally rely on manual or semi-automatic methods. In particular, manual methods can result in variations in coating thickness or uniformity depending on the operator's skill level. Consequently, this can lead to reduced anti-corrosion effectiveness, quality issues caused by poor coating, and inefficiencies such as the excessive use of anti-corrosion liquid. In particular, there is a growing need to improve these traditional anti-corrosion processes to meet the high production speeds and quality standards of automobile manufacturing lines.

Preferred embodiments of the embodiments are described in detail, and examples thereof are shown in the accompanying drawings. The following detailed description, with reference to the accompanying drawings, is intended to describe preferred embodiments of the embodiments rather than merely embodiments that may be implemented according to the embodiments. The following detailed description includes details to provide a thorough understanding of the embodiments. However, it is obvious to those skilled in the art that the embodiments may be practiced without these details. Most terms used in the embodiments are selected from those commonly used in the field, but some terms are chosen at the applicant's discretion, and their meanings are described in detail in the following description as necessary. Accordingly, the embodiments should be understood based on the intended meaning of the terms, rather than their mere names or meanings. Figure 1 shows a flowchart of a method for automating a rust prevention process according to embodiments. Referring to FIG. 1, the rust prevention process automation method according to embodiments may include the steps of: stopping a vehicle (S1000); inputting vehicle information data (S1001); obtaining vehicle stopping position information based on a camera (S1002); adjusting the nozzle head to be positioned at an entry position based on the input information data and the obtained position information, and inserting the nozzle head into a rust prevention hole provided in the vehicle (S1003); and spraying a rust prevention liquid when the insertion of the nozzle head is completed (S1004). The anti-corrosion process involves applying various methods to prevent metal surfaces from corroding; it is an essential step to protect metals from corrosion caused by oxidation, moisture, or salt. In the context of automobiles, the anti-corrosion process refers to the application of an anti-corrosion solution to finished vehicles before shipment to prevent rust caused by seawater when exporting overseas. Vehicles that stop at the S1000 stage are vehicles subject to rust prevention and may correspond to finished automobiles. The information data input in step S1001 may include vehicle type information and information regarding the location/number of anti-corrosion holes provided in the vehicle. The position information obtained in step S1002 can be obtained based on a camera. More specifically, the camera may be equipped in a rust-preventing liquid spraying device.
