An intelligent bearing detection device according to claim 6, wherein the lower ends of the two elastic air bags (27) are fixedly connected with an annular pressure plate (32), the upper end of the second annular plate (30) is provided with a plurality of grooves (33), and pulleys (34) are mounted in the grooves (33).

9. The intelligent bearing detection device according to claim 1, wherein the detection probe comprises a first infrared probe (6) and a second infrared probe (7) which are mounted on the outer wall of the lower end of the central column (5) and the inner wall of the lower end of the circular cover (4).

10. A bearing detection method using the intelligent bearing detection device as claimed in any one of claims 1-9, characterized in that the operation steps are as follows:

step 1: the bearing to be detected is uniformly placed on the conveying belt (1), and the conveying belt (1) conveys the bearing to be detected;

step 2: when the bearing is positioned at the lower end of the circular cover (4), the conveying belt (1) stops and the driving motor (9) is started;

and step 3: the driving motor (9) can drive the circular cover cap (4) to cover on a bearing on the conveying belt (1) through the threaded rod (11);

and 4, step 4: when the circular cover (4) slides downwards, the elastic air bag (27) is extruded, and the two arc-shaped plates (19) clamp the bearing, so that the axis of the bearing is collinear with the axis of the circular cover (4);

and 5: then the driving motor (9) drives the rotating shaft (12) to rotate reversely and simultaneously the infrared distance meter (39) is turned on;

step 6: the rotating pipe (15) can drive the circular cover cap (4) to rotate, so that the first infrared probe (6) and the second infrared probe (7) are driven to sweep circumferentially;

and 7: judging whether the currently detected bearing is qualified or not according to the radius value scanned by the infrared distance meter (39);

and 8: when the rotating shaft (12) rotates reversely, the circular cover (4) can be automatically separated from the bearings, at the moment, one bearing is detected, and then the steps are repeated to detect the rest bearings.
