[0079] The medium for low-acid pickling and high-acid pickling is hydrochloric acid. The low-acid pool is arranged in three groups, namely pickling pool 1 3, pickling pool 2 4 and pickling pool 3 5. The high-acid pool is arranged in three groups, namely pickling pool 4 6, pickling pool 5 7 and pickling pool 6 8. The pickling time of low-acid pickling and high-acid pickling is 3-4 minutes, and the temperature is 10-30°C.

[0080] The concentrations of hydrochloric acid in the pickling tank 1 3 , the pickling tank 2 4 , the pickling tank 3 5 , the pickling tank 4 6 , the pickling tank 5 7 and the pickling tank 6 8 are increased in sequence.

[0082] The water washing tanks are arranged in two groups, namely a first water washing tank 15 and a second water washing tank 16. The medium in the first water washing tank 15 is the recycled water of the second water washing tank 16, and the medium in the second water washing tank 16 is the treated recycled water.

[0083] The washing time is 2 minutes and the temperature is 10-30℃.

[0084] The phosphating medium is a phosphating solution, the temperature is 70-80° C., and the time is 3-5 minutes. When the present invention is implemented, two groups of phosphating pools 13 can be set up, and the phosphating work can be carried out twice.

[0085] The saponification medium is soap flakes, the temperature is 80-90°C, and the time is 2-3 minutes.

[0086] The time for immersion one and immersion two is 2 minutes, the temperature is 10-30℃, the flushing medium is condensed water or tap water, the time is 2 minutes, the temperature is 10-30℃, the medium of immersion one is the recycled water after flushing, and the medium of immersion two is the treated recycled water.

[0087] The pickling process is one of the core of the whole process. It mainly uses acidic solution to clean the wire to remove surface oxides and impurities, preparing for the subsequent phosphating treatment. The quality of this process directly affects the quality and performance of the final product.

[0088] The bulk material process is mainly to disperse the pickled wires for subsequent cleaning and processing. The purpose of this process is to prevent the wires from sticking to each other and ensure the smooth progress of subsequent processing.

[0089] The immersion cleaning process is to clean the wire with clean water or other solvents to remove the residues and other impurities left by the pickling process. The purpose of this process is to ensure the cleanliness of the wire surface, reduce the components of the pickling solution brought into the subsequent process, and prepare for other subsequent treatments.

[0090] The flushing process is to use high-pressure water to flush the wire to remove the residues and other impurities left in the immersion process. The purpose of this process is to further ensure the cleanliness of the wire surface and improve production efficiency.

[0091] The surface conditioning step is to treat the wire with a surface conditioning agent to improve the physical and chemical properties of the wire surface. The purpose of this step is to promote the phosphating process to form a fine and dense phosphating film and increase the phosphating speed.

[0092] Phosphating is to soak or spray the wire with phosphate solution to form a protective film on the wire surface. The purpose of this step is to improve the corrosion resistance and wear resistance of the wire.

[0093] The water washing step is to clean the wire with clean water to remove the residues and other impurities left by the phosphating step. The purpose of this step is to ensure the cleanliness and quality of the wire surface.

[0094] The saponification process is to treat the wire with a saponifier to form a lubricating film on the wire surface. The purpose of this process is to improve the lubricity and rust resistance of the wire.

[0095] The drying process is to remove moisture from the surface of the wire by natural or forced means to make the wire dry. The purpose of this process is to ensure the quality and performance of the wire in subsequent use or storage.

[0096] The quality control and testing phase is to ensure that the quality and performance of the final product meet the requirements by testing and controlling the quality of the wire. The purpose of this phase is to ensure that the products produced can meet customer needs and standard requirements.

[0097] When the present invention is implemented, the production line adopts multiple RGV vehicles to form a basic logistics system, which operates in a cyclic operation mode and is automatically controlled by a main control system. Each RGV vehicle runs along the track guidance direction and is automatically allocated to sequentially complete the process from material grabbing - pickling - water washing - phosphating - water washing - saponification - discharging.

[0098] Hook: It is lifted by the RGV and circulates between various processes of the production line. It is used to lift and fix the wires to ensure the stable operation of the wires on the production line. The number and configuration of the hooks can be adjusted according to the scale of the production line and the specifications of the wires.

[0099] Loading and unloading ground rail car: used to transport wires from the entrance of the production line to the designated location, or from the designated location to the exit of the production line, to achieve automatic loading and unloading of wires.

[0100] Flushing device: installed in the process tank of the flushing station of the production line, used to flush the wire and remove the residual pickling solution and phosphating solution, as well as other impurities on the surface of the wire. The flushing device is divided into internal flushing and external flushing, and can move along the predetermined track in the process tank. The internal flushing is used to flush the inside of the wire, and the external flushing is used to flush the outside of the wire. To ensure the flushing effect, a rotating roller is installed at the bottom of the flushing process tank, which can rotate the wire while flushing, so that the inside and outside of the wire are thoroughly cleaned.

[0101] Bulk material device: It is installed in the process tank of the bulk material station of the production line, and a rotating roller is installed at the bottom. RGV transfers the wire to the bulk material station, puts down the hook, and places the wire on the rotating roller. The rotating roller rotates synchronously to disperse the pickled wire, change the wire bonding surface, and ensure the removal of the oxide scale on the wire surface for subsequent cleaning and processing. The purpose is to prevent the wires from sticking to each other and ensure the smooth progress of subsequent processing.

[0102] When the present invention is implemented, it can be divided into regional control and a total of 6 vehicles. The time of each process stage is not fixed and can be adjusted as needed. It is suitable for workpieces with various process requirements. The RGV vehicles in steps S1 to S12 can be completed by 6 RGV vehicles. The first RGV vehicle is responsible for loading the material to the low-acid pickling process, the second RGV vehicle is responsible for low-acid pickling to high-acid pickling, and the third RGV vehicle is responsible for loading the material to the low-acid pickling process.
