[0027] In this device, the pressure roller bracket 5 is used to install and fix the pressure roller 6, and the pressure roller 6 can be raised and lowered in the gantry 2 under the drive of the cylinder 8. The base 1 is used to carry the gantry 2, the roller 3 and the pressure roller 6. The adjustment block 13 is used to support the rotating shaft 4 and the roller 3.

[0029] This device compresses steel pipes entering a machine vision inspection system, forcing them into a compressed state. This ensures more stable pipe transport and inspection, resulting in higher precision and accuracy in visual inspection. When a pipe is delivered to the rollers, a position sensor detects the incoming pipe and transmits a signal to a pneumatic cylinder. The cylinder, via a connecting rod, drives the roller support and rollers downward along the gantry until the pipe is compressed. The motor then turns, rotating the shaft and rollers. This rotation conveys the compressed pipe toward the machine vision inspection equipment. Because the pipe is gripped by the V-shaped grooves on the rollers and roller surfaces, and the rotation of the rollers provides the power for transport, the pipe maintains a straight, smooth path during transport, avoiding jitter or irregular movement, thereby ensuring that the machine vision inspection equipment obtains a good visual image. This device, with its simple structure, stable and reliable operation, and easy maintenance, ensures more stable pipe transport and inspection, significantly improving the accuracy of visual inspection for surface defects on pipes.
