The oxygen-free copper rod is placed in the middle of the mounting base 1. At the entrance of the inner groove, the conveying roller 3 at the conveying end starts to rotate driven by the driving motor 4. Thanks to the inner arc groove design on the conveying roller 3, the oxygen-free copper rod can be stably centered during the conveying process. When the oxygen-free copper rod enters the test area, the first test roller 5 and the second test roller 6 directly contact the surface of the copper rod to form the positive and negative contact points of the test circuit. The current passes through the oxygen-free copper rod, and the test circuit immediately measures the resistance value. The quality of the oxygen-free copper rod can be tested according to the change in the resistance value. After completing the resistance test of an oxygen-free copper rod, the driving motor 4 continues to work and sends the next copper rod into the test area for seamless and continuous detection.
