10. A method for using the plate surface crack detection device for all-round detection according to claim 9, characterized in that: The following steps are involved:

1. The workpiece is placed on the conveying assembly (1) and is conveyed by the conveying assembly (1) to the bottom of the detection assembly (4); Second, the steering engine (51) drives the rotating plate (52) to rotate, and the rotating plate (52) drives the calibration block (53) to rotate. When the calibration block (53) rotates to the bottom of the circular box (41) and is located directly below the probe (45), the probe (45) is calibrated; 3. The first driving motor (26) drives the threaded rod (22) to rotate, and the threaded rod (22) drives the connecting frame (23) to move vertically to adjust the height under the limiting and guiding action of the first sliding block (24) and the first sliding rail (25), and the connecting frame (23) drives the circular box (41) to move vertically to adjust the height; when the circular box (41) moves downward, it drives the straight limiting plate (31) and the arc-shaped guide plate (32) to move downward, and when the arc-shaped guide plate (32) moves downward, it contacts the plate and guides the plate to move, and then the position of the plate is calibrated through the straight limiting plate (31); Fourth, the second drive motor (42) drives the second gear ring (419) to rotate, the second gear ring (419) drives the first gear ring (410) to rotate, the first gear ring (410) drives the rotating disk (43) to rotate, the rotating disk (43) drives the detection unit to rotate, and under the guidance of the vortex groove (418), the ball bearing (422) is driven to move along the vortex groove (418), and at the same time, the detection unit is driven to translate inward along the transverse groove (44), so that the detection unit can rotate and move inward at the same time, so as to perform all-round detection of the plate.
