[0034] Working principle: During operation, the material rods 102 are placed in the placement box 101. When the material rods 102 need to be loaded, the limit block 113 is driven to move in the placement box 101.

The detection frame 304 drives the threaded shaft 306 to be sleeved on the U-bolt 209 and move on the U-bolt 209. According to the change of the torque sensor on the threaded shaft 306, it is judged whether the thread of the U-bolt 209 is qualified. If the threaded shaft 306 cannot move on the U-bolt 209 or the torque sensor value changes greatly, it means that the U-bolt 209 is not qualified. There is a problem with the thread of the bolt 209. The threaded shaft 306 drives the nozzle 305 to work while moving on the U-bolt 209. The nozzle 305 sprays lubricating oil on the U-bolt 209 to improve the detection accuracy of the thread of the U-bolt 209. After completing the detection of the thread of the U-bolt 209, the mounting plate 302 is driven to rotate on the mounting frame 301. The mounting plate 302 drives the wiping plate 303 to rotate.
