b. placing a cover ring (13): then placing the cover ring (13) on the watchcase assembly (12), lowering the lifting mechanism (5) to a preset position, and clamping the cover ring (13) by the upper clamping structure (3);
c. the cover ring (13) is pre-rotated: the pre-rotation mechanism (8) rotates the cover ring (13) to the starting position of the buckle between the cover ring and the watchcase, at the moment, the resistance to the cover ring (13) is increased and is larger than the torque of the pre-rotation mechanism (8), the pre-rotation mechanism (8) stops rotating, and then the locking mechanism (9) is started to clamp the rotating mechanism (4);
d. the cover ring (13) is screwed tightly: the rotating mechanism (4) rotates to screw the cover ring (13) with the watchcase;
e. and (3) resetting the device: after the rotating mechanism (4) reaches a set rotating angle, the upper clamping structure (3) is loosened, the rotating mechanism (4) returns, and the lifting mechanism (5) rises to a starting state;
f. and (5) taking out the workpiece: the upper clamping structure (3) is opened to take out the workpiece.
10. A meter bezel mounting method employing the meter bezel mounting device of any one of claims 6 to 8, comprising the steps of:
a. the watch case assembly (12) is clamped: placing the watchcase assembly (12) on the lower clamping structure (2) and clamping the watchcase assembly (12) by the lower clamping structure (2);
b. placing a cover ring (13): then placing the cover ring (13) on the watchcase assembly (12), lowering the lifting mechanism (5) to a preset position, and clamping the cover ring (13) by the upper clamping structure (3);
d. the cover ring (13) is screwed tightly: the rotating mechanism (4) rotates to screw the cover ring (13) with the watchcase;
e. and (3) resetting the device: after the rotating mechanism (4) reaches a set rotating angle, the upper clamping structure (3) is loosened, the rotating mechanism (4) returns, and the lifting mechanism (5) rises to a starting state;
f. and (5) taking out the workpiece: the upper clamping structure (3) is opened to take out the workpiece.
