When the follower 14 is pushed by the flat cam η, it can drive the punch upper seat 18 and the punch 24 to move downward at the same time. At this time, because the punch lower seat 20 is pressed against the slide upper plate 26 (Refer to Figure 丨). Therefore, the punch body 242 passes through the through hole 2101 of the lower seat 20 and the through hole 341 of the upper plate 26 to punch the flexible circuit board 40. hole. Referring to FIG. 5, the mandrel of the rotating device 10 continues to rotate. As the eccentric outer surface of the flat cam 12 adds the restoring force of the elastic body 22, the punch upper seat 18 and the follower 14 move upward. It moves, and because the second slot 182 in the punch upper seat 18 abuts against the clamping head 241 of the punch 24, when the punch upper seat 18 moves upward, the punch 24 moves upward. Then, the flexible circuit board 40 is moved, and when the mandrel of the rotating device 丨 0 is continuously rotated, the punching action shown in FIG. 4 and the restoring action shown in FIG. 5 can be performed again. The advantages of the present invention are as follows: 1. The use of a flat cam can reduce the lateral force generated by the punch, reduce the gap between the punch and the die, and improve the burr problem that may occur on the flexible circuit board. 2. The rotation speed of the flat cam can be improved by increasing the speed of the servo motor 'to shorten the processing time at a higher punching rate' to increase production capacity in the South. 3. By adjusting the center of gravity position of the flat cam, the dynamic performance of the system can be stabilized.
