The product is placed on the carrier table 2, the first lifting driving mechanism 31 drives the connecting plate 32 to move downwards with the pressing plate 34 and the second lifting driving mechanism 33, so that the carbon brush 100 of the product penetrates into the through hole 341 of the pressing plate 34, and the pressing plate 34 abuts against the base 101 of the product, then the second lifting driving mechanism 33 drives the top rod 35 to move downwards and penetrate into the through hole 341 of the pressing plate 34, the top rod 35 pushes the carbon brush 100 to move downwards, and stops when the second lifting driving mechanism 33 drives the top rod 35 to push the carbon brush 100 to move to the zero reference distance, then the second lifting driving mechanism 33 drives the top rod 35 to move upwards along the through hole 341 of the pressing plate 34 by 3mm, while the head of the carbon brush 100 rebounds to a position 3mm away from the base 101 under the force of the spring 102, then the spring force value of the carbon brush 100 at the distance of 3mm is detected by the pressure sensor 36, and whether the spring force value of the carbon brush 100 at the distance meets the requirements is detected.
