The control host determines the position of the carrier frame 10 according to its own algorithm and sends a stop command to the first control chip 75, so that the carrier frame 10 is located directly above the pickling tank 2. Then, a motion command is sent to the second control chip 82 to drive the carrier frame 10 to move downward to the pickling tank 2 for pickling.

[0028] Embodiment 4: A method for processing an anti-corrosion steel pipe, using the above-mentioned anti-corrosion steel pipe processing device to perform anti-corrosion treatment on the steel pipe, comprising the following steps: S1: placing the cut steel pipe into a carrying frame 10 and transferring it to a pickling tank 2 for pickling; S2: The pickled steel pipe is transferred between the pickling tank 2 and the passivation tank 3 for washing; S3: transferring the rinsed steel pipe to the passivation tank 3 for passivation treatment; S4: The steel pipe after passivation treatment is transferred to between the passivation tank 3 and the electroplating tank 4 for rinsing; S5: The steel pipe is transferred to the electroplating tank 4 for electroplating, then taken out and transferred to a drying device for drying.

[0029] During the anti-corrosion treatment of the steel pipe, the cut steel pipe is first inserted into the carrier frame 10 to ensure that each steel pipe is spaced apart to ensure the effect of subsequent pickling and electroplating. Then, the control host sends a control instruction to the first control chip 75 to move it to the top of the pickling tank 2. The method determines the position of the carrier frame 10 and sends a stop instruction to the first control chip 75 to make the carrier frame 10 located above the pickling tank 2. Then, a movement instruction is sent to the second control chip 82 to drive the carrier frame 10 to move downward to the pickling tank 2 for pickling. During pickling, in order to improve the pickling efficiency, the control host sends a control instruction to the first control chip 75 and the second control chip 82. The control chip 82 simultaneously sends motion instructions to make it move back and forth in a short distance, so that the supporting frame 10 moves slowly up, down, left and right in the pickling tank 2, thereby improving the pickling efficiency and the pickling effect; the control host also controls the pickling time through an algorithm, and after reaching the preset time, it sends a motion instruction to the second control chip 82 to make it rise, and then sends a motion instruction to the first control chip 75 to move it to the position of the spray head 9 for washing and then to the passivation tank 3 for passivation treatment. Finally, after being electroplated in the electroplating tank 4, the supporting frame 10 slides out of the discharge port of the processing warehouse 1 and descends to the working height, and the staff transfers the electroplated steel pipes to the drying equipment for drying.
