10. A fully automatic dial pointer press-fitting method, using the fully automatic dial pointer press-fitting device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: When the dial pointer needs to be press-fitted, the positioning mold (104) is transported by the conveyor belt (103). When it is transported into the box (102), the dial is adsorbed by the pneumatic suction cup (108) of the first manipulator (107) and placed on the positioning mold (104) for positioning. Then, the second manipulator (109) drives the mounting plate (10) to move to the top of the first material tray (105). Then, the second manipulator (109) drives the mounting plate (10) to move downward so that the rectangular tube (1102) fits the pointer. At the same time, the solenoid valve (302) is opened and the external exhaust device is used to perform the exhaust operation, so that the exhaust hole (1104) can be used to exhaust air, thereby adsorbing the pointer. Then, the second manipulator (109) moves to the top of the dial and press-fits the three pointers in turn. S2: When the press-fitting is performed, the second manipulator (109) drives the mounting plate (10) and the pointer to move downward. When the pointer is pressed onto the pointer shaft, the second spring (203) can be gradually compressed, and the distance between the mounting plate (10) and the rectangular tube (1102) gradually decreases. At the same time, the change in the distance of the rectangular tube (1102) is detected by the distance sensor (204), and the compression amount of the second spring (203) can be determined, and then the extrusion force of the rectangular tube (1102) on the pointer during press-fitting can be determined, thereby ensuring the quality and efficiency of the press-fitting. Moreover, when the annular tube (1103) moves downward, the connecting plate (502) can be driven to move downward by the second L-shaped plate (501) and the connecting rod (505), and the moving block (503) and the V-shaped block (504) can be driven to move downward by the telescopic mechanism, so that the V-shaped block (504) can be aligned with the pointer shaft and located below the pointer body; S3: When the mounting plate (10) moves toward the direction approaching the rectangular tube (1102), it can drive the push plate (701) to move downward. When the inclined surface (702) abuts against the top of the moving block (503), the two moving blocks (503) can be pushed to move closer to each other. At the same time, the third spring (603) is compressed, and the V-shaped block (504) abuts against the side wall of the pointer shaft, thereby clamping and fixing the pointer shaft. Moreover, when the push plate (701) moves downward, it can drive the multiple triangular blocks (803) to move downward through the L-shaped frame (802) and the one-way rotation mechanism. When the triangular block (803) abuts against the end of the push rod (801), the triangular block (803) can rotate upward along the rotating shaft (902). At this time, it will not push the T-shaped guide rod (402) to move. S4: After the pressing is completed, the second manipulator (109) drives the mounting plate (10) to move upward. At this time, the second spring (203) gradually resets. At this time, the plurality of triangular blocks (803) can be driven to move upward by the push plate (701) and the L-shaped frame (802). When the triangular block (803) abuts against the end of the push rod (801), the stop block (904) can abut against the side wall of the limit block (905), so that the triangular block (803) cannot rotate downward. At this time, the T-shaped guide rod (402) can be pushed away. The push rod (801) moves in the direction away from the triangular block (803), and at the same time, the first spring (403) is compressed. When the end of the push rod (801) passes over the triangular block (803), the T-shaped guide rod (402) can move and reset under the action of the first spring (403). This reciprocating movement can make the T-shaped guide rod (402) move back and forth, and at the same time, drive the rubber rod (404) to move back and forth and can abut against the side wall of the pointer body. The visual sensor (405) is used to observe whether the pointer body rotates, so as to determine the tightness after press-fitting.
